Description

Known slope of the math-like driveway, mainly for logging.

It consists of a carrying rope and a carriage moving along it, moved by a combined t-gogo-lifting rope. The carriage has a device for locking with a control locking support fork, which is under the influence of a cargo hook with a tapered head. The carriage stops only when interacting with the support fixed on the supporting cable. Such a device does not allow the carriage to be locked in an arbitrarily specified position on the support cable.

The proposed inclined overhead cableway is characterized in that the carriage stop device is mounted longitudinally-movably in the carriage itself. The device blocking the carriage is made in the form of wedges compressing the unsaturated rope, while the carriage body reverses. The control wedge latch with latch interacts with the load hook through a lever spring-loaded system, including gear ratchet wheels. This design solution provides a carriage stop at any given portion of the carrying rope.

All control of the operation of the carriage, including raising and lowering the load, is carried out by a winch, which carries it out with a winch drum cable. The cable from the winch to the carriage is both pull and lifting.

FIG. 1 shows a carriage device, side view; in fig. 2 - trolley, in two projections; in fig. 3 - carriage body with a trolley, top view; in fig. 4 - brake, side view and section along A-A.

The carriage body 1 consists of two cheeks, made of sheet steel. One of the cheeks has a longitudinal hole for the passage of the carriage through the support brackets holding the supporting cable 2. In the upper part of the cheeks four rails 3 are welded along the edges, resting on the support rollers 4 of the carriage. These slats allow the carriage to be rolled relative to the cart by 100 mm. Four strips 5 are welded to the carriage body's cheeks No. 132558-2, which in the assembled carriage body form between them a slot for the racks of the support cable brackets and do not allow the carriage to come off. Each carriage cheek has a cavity for placing a wider brake housing 6 therein, taking into account the possibility of movement of the brake along the carriage housing by 100 mm. The carriage carriage is a separate unit and consists of a frame 7 of two cheeks, fastened along the edges with strips 8, two riding rollers 10 mounted on axles 9, and four support rollers 4, on which the carriage body rails 3 are supported. When the carriage is in operation, the cart is supported on the carrying cable by 2 driving rollers 10, and the carriage body is supported by the rails 3 on the support rollers 4 of the trolley. Thus, the carriage can move along the carrying cable and at the same time with its body move relative to the cart in that other direction. The brake body 6, located between the carriage body cheeks, is a frame with transverse steel bars, on the edges of which four rollers 1} of a hemispherical shape are vertically mounted. The rollers when moving the brake housing to the left clamp the wedge J2 on the suspension cable. The wedge 12 is connected to the frame of the cart on the finger with the help of planol / and is made in the form of long plates installed along the carrying cable. On the cable side, the wedges have a longitudinal hemispherical undercut, and on the other hand, two paconic protrusions into which the rollers 11 move. The strips holding the wedge are constantly unfolded by a spring, in order to eliminate their friction against the supporting cable. To close the brake casing 6 in the extreme position (during braking) on the rear wall of the carriage housing, the brake shutter assembly is attached. The shutter 14 with the latch 15 under the action of the spring 16, at the moment when the brake housing moves to the right, closes the brake housing, and the latch 15 under the action of the spring 17 enters the longitudinal gear on one of the brake wedges. The lever 18 serves to release the carrying cable. The mechanism that ensures the capture of the logs and their unloading is fixed on one of the carriage cheeks. It includes a support roller 19, mounted on one palp 20 with asterisks 21 and 22 on ball bearings. On both sides of the support roller are symmetrically arranged sprockets with a versatile orientation of the teeth: teeth-like 21 (2 pcs.), Adjacent to the walls of the support roller, and three-toothed 22 (2 cm.), Adjacent to the walls of the carriage. In addition, the asterisks behind the oyorpym roller (in Fig. They are not visible), made teams. The three-tooth sprocket can, with respect to the tooth-tooth, rotate 30 ° to the left and return back with a spring. The spring-loaded sprocket interacts with the lever 18, and the ne-podgruul inenna interacts with the lever 23, welded to the support fork 24. Through the support roller, re-traction cable 25, passing through the fork 26, with two ends covering the support roller 19 and interacting with two six-pointed asterisks . When the cable is tensioned, the cone 27, which is at its end, rests against the plug with its head. Having overcome the resistance of the spring 28, the cone will lift the fork, and it will turn the six-pointed asterisks by 60 °. At the same time, the fork also rotates three-tooth sprockets: one by 60 °, and the other (rear) by 30 ° (the remaining 30 ° do not have a spring after removing the load of lever 18 from the asterisk). The fork 26 returns to its initial position against the stop 29 by force of the springs 28. The latch of small stars 30 is made in the form of a fork and interacts with two six-tooth asterisks. Its purpose is to prevent the asterisks from turning back when the plug 26 returns to its original position, and also to keep the plug 24 in the open position.

on the plug 24 of the cone 27 serves to hold the cone in the carriage. This fork covers the plug 26 with its cheeks. It is fastened to the carriage body with threaded fingers screwed on both sides into the cheeks of the carriage body. The cone 27 is a thick-walled tube, at one end of which there is a conical head with a notch for the nozzle and socket of the plug 24, and at the other end is a device for hanging the chokers.

The carriage works as follows (for the variant, when the wood is moving down the slope of the cutting area). The carriage, with the end of the traction cable attached to it with chokers, with the help of a winch, rises upwards along the carrying cable. The total resistance to movement of the carriage up with a slope of 20 ° will be approximately 40-50 kg. Therefore, the spring 25 must be adjusted to the initial resistance of 60-70 kg. The carriage cart along with the wedges that are illuminated to it. The brakes are shifted to the far left. The brake is open and does not hinder upward movement. The bolt lock 14 with the latch / 5 and the lever 18 are deflected downward. One of the teeth of the three-tooth sprockets is in the vertical position, and also two teeth of small tooth-like sprockets are standing.

When the winch stops and the rope 25 is weakened, the carriage will move back under the weight of its weight. Driving rollers / (. Are constantly braked by rollers 32 having an outer rim of rubber. Pressing rollers 32 to the driving rollers is adjusted so that the car itself without the carriage on the supporting cable does not roll down on a slope of 20 °, but assembled with the carriage rolled down freely. With this adjustment, when the cable is loosened, the carriage body will first move downward relative to the carriage and then the carriage, together with the wedges 12 and the brake body 6, will be in the extreme right position.The shutter 14 will rise up under the action of the spring 16 and close the building from the brake and the carriage will stop.

T gsvy cable by means of a cone 27, breaking the resistance of a spore 28, will lift the plug 26. This fork will turn the toothy stars by 60 ° with its ends. The three-tooth sprocket 22 will come into contact with the lever 23 with its tooth and deflect the support fork 24 to the right, and the three-tooth sprocket on the other side of the support roller 19 will fit the tooth close to the lever 18. The latch 15 reliably holds the carriage on the brake. In this polishing, the cable is mounted behind the load. After attaching the load and lifting it, when the cone 27 enters and stops in the fork 26, it reverts the sprockets by 60 °. At the same time, at the very beginning of the turn, the lever 23, which is supported by the tooth of the sprocket, will jump off of it and the support fork of the cone 24 will be deflected by the spring 31 to the left, i.e. the landing seat will rise under the cone head. When a cone enters the carriage, it is released and gets a movement in the direction of the winch, i.e. upwards.

The winch turns off the winch and starts the carriage down by self-starting, slightly decelerating the drum with a brake.

When the carriage approaches the place of unloading, according to the signal, the windrower reduces the speed of the carriage movement and, at the second signal, turns on the winding cable until it is tensioned. The carriage is braked again and opens the exit to the cone. With the drum off. on the brake, the winch lowers the load.
