Abstract
The utility model relates to a synchronous self-locking safety tongs, belonging to the field of steeplifting transportation device, in particular to safety device of material hoister in building industry. In recent years, the utility model solves the problem that material hoisters used in building industry have no synchronous emergency reaction safety devices. In the utility model, a safety gear comprises a main connecting rod, a connecting sloping block, a friction sloping block, a synchronous transmitting mechanism and a casing; the safety gear is characterized in that the main connecting rod is communicated with a sensor device with no safety factor external force; the synchronous transmitting mechanisms forms a synchronous drive by that the main connecting rod goes through a shaft, an eccentric wheel and transmission gears which respectively drive the connecting sloping block to have horizontal motion; the friction sloping block has vertical motion to pinch guide rails and to make a cage not generate downward displacement to stop immediately. The utility model has sensitive reaction, high rapidity, high safe reliability, easy installation and easy operation and provides higher equipment safeguard for implementation of building industry.
Description
Technical field
The synchronous self locking safety pincers of the utility model belong to vertical-lift transportation device field, particularly building industry material elevator.
Background technology
Material elevator for building is a kind of vertical transport equipment that generally is used in construction site, and this device ' plays crucial effects to personal safety as well as the property safety.Belong to the indoor elevator of vertical transport equipment and mine elevator etc. together, promptly relatively stable after be in place, adjusting track, rare dismounting.And material elevator for building makes its dismounting frequent because of its special operating environment and operating mode demand, thereby causes it to promote the track inaccuracy.With this understanding, as do not have particular security device, when material elevator during along the upper and lower operation of track, loading cage accidental falling takes place also just be difficult to avoid, not only cause any property loss, even more serious is to cause personal injury.Regrettably, up to the present, the material elevator that building industry is used does not still have the safety device of synchronous emergency reaction, and therefore, the synchronous safety device becomes the outer in the industry common eager problem of paying close attention to.
Summary of the invention
There is not the problem of synchronous self locking safety device in order to solve material elevator for building, particularly at the building operation material elevator because of frequent dismounting, cause gig track inaccuracy, and cause the problem of load-carrying cage accidental falling, the special synchronous self locking safety pincers of the utility model design plan that proposes.
1, the self locking safety pincers comprise main connecting rod (1) synchronously, accept skewback (2), friction skewback (3), synchronous drive mechanism (4) and housing (5), it is characterized in that main connecting rod (1) is communicated with non-safety factor external force sensing mechanism, synchronous drive mechanism (4) is formed synchrodrive by main connecting rod (1) by main shaft (6) and eccentric wheel (7) and transmission gear (8), eccentric wheel (7) with accept skewback (2) and be connected, transmission gear (8) is connected with friction skewback (3) by drive link (9), and housing (5) inner bottom surface has track (11).
2, synchronous self locking safety pincers of the present utility model, its feature drives eccentric wheel (7) rotation from the main connecting rod (1) that is synchronous drive mechanism (4) by main shaft (6), and promotes to accept skewback (2) along housing (5) track (11) horizontal motion.
3, synchronous self locking safety of the present utility model clamps, and it is characterized in that the main connecting rod (1) of synchronous drive mechanism (4) drives transmission gear (8) simultaneously by main shaft (6), drives friction skewback (3) perpendicular movement through drive link (9).
4, synchronous self locking safety pincers of the present utility model is characterized in that said friction skewback (3) surface is equipped with friction lining (9).

Specific embodiments
The synchronous self locking safety of the utility model pincers are installed on the loading cage, form an integral body with cage, and the guide rail of gig is inserted between the friction skewback 3 of two symmetries.In the normal operation working process of cage lifting, synchronous safety pincers and cage synchronized operation, when any safety hazard external force took place, the self-locking synchronously immediately of safety pincers stoped cage to glide.For example out of service in the somewhere of operation when cage, when material loading or discharging, must open the door of cage, just when opening the door, this external force is passed to the main connecting rod (1) of safety tongs by the external force sensing mechanism; For another example, when wire cable rupture or the downslide of cage hypervelocity took place in operational process cage, the external force sensing mechanism all can pass to this unidirectional force main connecting rod (1), and it is moved downward, and drove safety tongs and finished safety clamping function.Now further specify in conjunction with the accompanying drawings: when external force that main connecting rod (1) is accepted to be transmitted by the external force sensing mechanism, move downward immediately, by main shaft (6), drive eccentric wheel (7) rotation, promotion is accepted the track (11) of skewback (2) in the housing (5) to gig orbit (13) direction parallel motion, when above-mentioned main connecting rod (1) drives eccentric wheel (7) rotation by main shaft (6), transmission gear (8) turns round simultaneously, and the drive link (9) that drives the one end moves, thereby driving friction skewback (3) moves vertically upward, make rapid and guide rail (13) the generation friction of friction lining (10), as pliers, clamp guide rail, cage can not be produced to bottom offset promptly stop for thirty years of age.After the non-safety factor external force of main connecting rod to be acted on (1) disappeared, main connecting rod (1) was subjected to locating piece (12) restriction to be returned to original position, and safety tongs is returned to previous status.
These synchronous self locking safety pincers are not only applicable to the building industry material elevator, can be installed on elevator cab or the mine elevator bridge railway carriage or compartment yet, and itself and bridge railway carriage or compartment are connected as one, and promptly further provide safety on this type of accurate guide rail.
The utility model can be installed on the elevator of building operation, is inserted into respective track and cage one and moves up and down along guide rail, improves the safety performance of elevator greatly.
Example 1: for SS type building construction hoist, install guide rail additional, can use the safety pincers in its standard knot outside.
Example 2: for SSE type building construction hoist, the one side relative at its standard knot installs guide rail additional, can use the safety pincers.
Example 3: for SSF type building construction hoist, install guide rail additional, can use the safety pincers in the standard knot inboard.
