Abstract

A short-distance moving vehicle is composed of a direct-current motor, a speed change mechanism, a gear, a rack, wheels, rolling bearings, pressure bearings, a storage battery, a charger control system and a controller. The short-distance moving vehicle has the functions of moving forwards, moving backwards, turning left, turning right and stopping; oil purification equipment of a transformer substation can be permanently placed on the short-distance moving vehicle and move in the transformer substation along with the vehicle; and an operator who follows the vehicle and is located beside the vehicle uses a wireless controller or control keys on the vehicle for carrying out moving operation with multiple motions, and therefore the labor intensity of a worker is greatly reduced.

Description

Short-distance movement car

Art

The present invention is applicable to the short-distance movement of transformer oil cleaning equipment of power plant, transformer station, is in order to avoid people many when mobile oil purification equipment (equipment is generally at 2-4 ton) carries out.Mobile in the field that this short-distance movement car is also applicable to other factories and miness equipment or weight.

Background technology

At present known in power plant, transformer station want regularly purify the transformer oil oil purification equipment in transformer, because oil purification equipment does not use at ordinary times, equipment need be shifted onto transformer place from storehouse during every use, the weight of next oil purification equipment of normal conditions is at 2-4 ton, many people are needed to carry out (general transformer station, power plant are not equipped with lifting appliance) time mobile, the castor of conventional oil purification equipment is less, runs into turning situation and moves very difficult.For solving an above difficult problem, we provide a kind of short-distance movement car conveniently making oil purification equipment moving put in place.The similar vehicle of the present invention, it is the load-carrying mobile device that an energy wireless controller is advanced synchronous with people.Oil purification equipment is placed on locomotive do not affect and carries out oil purification work to transformer, conveniently starts, meets the expectation of on-the-spot first-line staff.

Summary of the invention

The present invention is made up of direct current generator, gear, rack-and-pinion, universal wheel, rolling bearing, pressure bearing, storage battery, charger, control system, wireless controller etc.

Component function

To advance driver element: this unit is powered to direct current generator by storage battery, through gear reduction of speed, gear driven main axis.

Turn to driver element: this unit is powered to direct current generator by storage battery, through gear reduction of speed, tooth bar drags and turns to swing arm to move.Control unit 1: this unit is made up of electric-control system and Digiplex, completes the functions such as advance, retrogressing, left-hand rotation, right-hand rotation, parking.

Control unit 2: this unit is made up of collision avoidance system, mechanical, electrical security system.

Technical scheme

The present invention is the convenient concept of movement of oil purification equipment and the approach of electric-mechanic control system mainly.Its scheme key link is that storage battery drives low gait of march and can carry weight two links.By 220V alternating current, the storage battery on short-distance movement car is charged.Low rate request velocity of rotation of advancing is low, and the rotating speed of motor is all very high.Loads is advanced and is required that axle moment is very large, and the rotating torque of direct current generator is all very little, these two key problems both can make velocity of rotation reduce by a gear, met slow-speed of revolution requirement, rotating torque can be made again to improve simultaneously, meet the requirement that weight is driven.So one turns gear and makes two problems be resolved simultaneously.Load the height of oil purification equipment region between 200mm to 600mm, by different model, its translational speed is equipped with anticollision at 2 ms/min to 50 ms/min respectively and automatically stops stopping means and manual emergency stop device, ensures safety traffic.

Detailed description of the invention:

In Fig. 1 example, mobile short distance car sends by wireless controller advance key 2, back spacer 3 and advances or retreat instruction.Send or right-hand rotation instruction by left-hand rotation key 4, right-hand rotation key 5.By on & off switch 1, stop key 6 transmit button or halt instruction.

In Fig. 2 example, when the wireless receiver on mobile short distance car after wireless controller sends instruction receives corresponding operating instruction, control to advance electrical motor gearshift mechanism 12 or steer motor gear 18 action.Also each operational order is realized to control by vehicle-mounted key device advance motor and steer motor.When mobile short distance car is when advancing or run into barrier in turning process, crashproof urgency is endured switch and is automatically stopped, and warning lamp is reported to the police.

In Fig. 3 example, install directional wheel 9 by main shaft 10 both ends of the surface, directional wheel 9 is connected with rolling bearing 8, and rolling bearing is arranged on bearing block 7.By advancing, electrical motor gearshift mechanism 12 is connected with gear 11, drives main axis to complete advance, the fallback function of directional wheel 9.

In Fig. 4 example, steer motor gear 18 is connected with gear 19, and gear 19 engages with tooth bar 17, punches in tooth bar 17 both ends; Swing arm 15 is connected by rolling pressure bearing 13 with universal wheel 14, and tooth bar 17 punching place is inserted in the punching of swing arm 15 one end, and rotating shaft 16 penetrates this hole and swing arm 15 is connected with tooth bar 17.

In Fig. 5 example, Fig. 3 is advanced and drives transmission and diagram 4 to turn to driving transmission to be connected with chassis 26, to fix.Charging plug 20 is connected with 220V AC power, can charge to low-voltage direct storage battery 22 and low-voltage direct storage battery 24.When pressing wireless controller advance key 2 or back spacer 3 sends advance or retreats instruction, low-voltage direct storage battery 22 is to powered by direct current electric machine rotation of advancing, pot motor drives gear, the slow-speed of revolution of its gear, high torque (HT) driving shaft, main shaft 10 is driven by gear 11, main shaft 10 drives directional wheel 9 to rotate, and locomotive is run at a low speed forward or backward.When wireless controller sends left-hand rotation 4 or right-hand rotation 5 instruction, low-voltage direct storage battery 24 is powered to the direct current generator rotated, electric machine rotation pot motor drives gear, the slow-speed of revolution of its gear, the driving shaft of high torque (HT) drive tooth bar 17 left or right to move by gear 19, tooth bar 17 and swing arm 15 one, so swing arm 15 drives universal wheel to rotate, the time that Digiplex steering order sends is long, then take turns to corner large, steering order transmitting time is short, and the corner of taking turns is little, and the angular speed change of wheel is ordered about locomotive and changed direct of travel.
