Abstract
The utility model discloses an elevator safety tongs aggregate unit, it can be pressed by the hitch plate that fag end board arrives, fix the limit switch that can be pressed by the hitch plate and triggered when fag end board on elevator car presses on the hitch plate when the towline of elevator breaks including sliding the setting on elevator car, limit switch be connected with the control system of elevator. The safety gear linkage device with the structure can ensure that the traction machine can stop working in time when the traction rope is broken, thereby improving the safety and reliability of the elevator; the structure is simple and the installation is convenient; the structure comprises a testing device, so that the field debugging is convenient.
Description
Technical field
The utility model relates to a kind of safety tongs linkage of elevator, and it can be connected the rope hitch plate of elevator with safety tongs, belong to the elevator technology field.
Background technology
Generally speaking, the elevator that adopts hoist ropes to drive, when the unexpected fracture of hoist ropes, the safety tongs linkage drives the safety tongs action, and car is clipped on the guide rail.Yet this moment, the whole electric system of elevator may in time not disconnect, towing machine still works on, and causes the guide rail gross distortion.And existing safety tongs linkage structure is complicated, cost of manufacture is higher, and also has the problem of Installation and Debugging inconvenience.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of safe reliability that can improve elevator, the timely out-of-work safety tongs linkage of towing machine when guaranteeing the hoist ropes fracture.
The purpose of this utility model is achieved in that a kind of elevator safety gear linkage, it comprises the interlock plate that can be pressed onto by rope hitch plate that is slidingly arranged on the lift car when the fracture of the hoist ropes of elevator, be fixed on the limit switch that can be pressed onto and be triggered by the plate that links when rope hitch plate is pressed on the interlock plate on the lift car, and described limit switch is connected with the control system of elevator.
Be provided with the retracing spring that is in the state that makes that described interlock plate and described limit switch are separated between described interlock plate and the lift car.
Also be provided with the connection spring on the described interlock plate, described connection spring one end is connected with described interlock plate, the other end is connected with safety tongs.
The rope hitch plate place that is positioned at elevator on the described interlock plate also is provided with when fracture takes place the hoist ropes of elevator and can be re-packed by the switch that rope hitch plate is pressed onto.
Also be connected with the test rope on the described interlock plate.
Because the utilization of technique scheme the utlity model has following advantage: towing machine can in time quit work when the safety tongs linkage of this kind structure can be guaranteed the hoist ropes fracture, had improved the safe reliability of elevator; And its simple in structure, convenient installation; Comprise proving installation in the structure, make things convenient for field adjustable.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
A kind of elevator safety gear linkage, it comprises the interlock plate 2 that is slidingly arranged on the lift car, is fixed on the limit switch 7 on the lift car, and described limit switch 7 is connected with the control system of elevator.Be provided with retracing spring 3 between described interlock plate 2 and the lift car, described retracing spring 3 is in the state that makes that described interlock plate 2 and described limit switch 7 are separated.Referring to Fig. 1, described retracing spring 3 is in compressive state, makes described interlock plate 2 be separated with described limit switch 7.
Also be provided with connection spring 8 on the described interlock plate 2, described connection spring 8 one ends are connected with described interlock plate 2, the other end is connected with safety tongs 10.
Also be connected with test rope 12 on the described interlock plate 2.After the installation of safety tongs linkage, pulling test rope 12 detects the action sensitivity of safety tongs 10 and the reliability of The whole control system, guarantees the reliable operation of device and passenger's the security of the lives and property.
