By the lifting of the frictional force drives car between steel wire rope and traction sheave grooving；The effect of wherein counterweight is the weight for balancing car
Amount, reduces the load of traction machine, realizes the energy-conservation of elevator, and its weight is equal to the half that car is conducted oneself with dignity plus elevator nominal load,
When having remarkable space below the elevator hoistways, one and Elevator weight sensor fall, it would be possible to cause casualties.
Safety tongs device is a kind of safety device that current Elevator weight sensor is generally used, when hypervelocity, disconnected rope etc. occurs in counterweight
During failure, elevator governor drives safety tongs action, and counterweight is clamped on guide rail, while safety switch cutting-off controlling system
Safety return circuit, it is to avoid the generation of accident.The safety tongs and safety switch of the counterweight of existing elevator are triggered by different modes, machinery
Coordination is poor, it is impossible to give full play to the safeguard function of counterweight safety device.
Utility model content
In view of this, the purpose of this utility model is to provide one kind and can improved while trigger safety tongs and safety switch
Both coordinations, give full play to a kind of elevator safety linkage of the safeguard function of counterweight safety device.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of elevator safety linkage, including：
- safety interaction base, it includes left base and right base；
- movable rotation-shaft, it transfers with safety interaction base activity, including left rotary shaft and right spindle, the left rotary shaft
Correspondence is through the forward and backward side plate of the left base, forward and backward side plate of the right spindle correspondence through the right base；
- gangbar, the one end of its two ends respectively with the left rotary shaft and the right spindle is movably hinged, the left rotary shaft and
The other end of the right spindle has been respectively fixedly connected with feeler lever, is fixedly connected with the side plate of the left base and the right base
With the corresponding safety switch of feeler lever difference；
- handle rod, it is connected with the right spindle, and the handle rod is connected with elevator speed limit rope；
- safety tongs, it includes the left safety tongs and right safety tongs that correspondence is connected with the left base and the right base,
The voussoir correspondence of the left safety tongs is connected with the left rotary shaft, and voussoir correspondence and the right spindle of the right safety tongs connect
Connect.
Preferably, above-mentioned a kind of elevator safety linkage, wherein the left rotary shaft and the right spindle respectively with institute
State and be rotatably connected to left contiguous block and right contiguous block at gangbar opposite ends link position respectively, the two ends point of the gangbar
Dui Ying not be pivotally connected with the left contiguous block and the right contiguous block.
Preferably, above-mentioned a kind of elevator safety linkage, wherein being fixedly connected with the front side board of the right base
Limiting plate, the limiting plate is provided with spacing hole, and the gangbar passes through the spacing hole.
Compared with prior art, the utility model advantageous effects are mainly reflected in：When elevator runs speed in the technical scheme
There is abnormal, elevator governor action in degree, and handle rod is pulled up by elevator speed limit rope, and handle rod drives right spindle to rotate,
Drive gangbar to rotate, and then drive left rotary shaft to rotate, so as to disconnect safety switch with movable feeler lever, so that cutting-off controlling system
Safety return circuit, meanwhile, movable rotation-shaft, which is rotated, rapidly lifts the voussoir of safety tongs, and counterweight is clamped on guide rail, stops elevator
Only run.
Brief description of the drawings
