Structure completes being automatically stopped for elevator, avoids elevator damage and casualties, and when object is interfered in discharge, elevator is then
It can restore normal operation, improve the safety of equipment operation.
To realize that the demand, the utility model are achieved through the following technical solutions above-mentioned purpose：On a kind of elevator
Lower operation collision prevention device, including doorframe, guardrail, square tube, steel wire rope, idler wheel, counterweight and electric limiting switch；The doorframe is
The single open-door doorframe of building hoist, is provided with guardrail at the top of the doorframe, and the square tube is arranged in the both sides of doorframe, respectively edge
The side extended line of doorframe extends certain distance, the steel wire rope setting, one end side of passing through of steel wire rope inside square tube
Pipe is fixed with doorframe lower-left end, and the other end passes through the circle roller being mounted in doorframe bottom righthand side square tube, is passed through right doorframe square tube, is arrived
Up to the square tube idler wheel of guardrail right end, then be parallel to the crossbeam of doorframe and span at the square tube on the left of guardrail, steel cord ends with match
Heavy phase connects；Entire steel wire rope C-shaped structure under the support of square tube and idler wheel；
Electric limiting switch is provided with above the counterweight, switch triggering site is arranged on the channel that counterweight rises.
Further, a kind of elevator runs collision prevention device up and down, and the guardrail welds for hollow tube, guardrail shape
For rectangular frame structure, the height of the guardrail is less than across the steel wire rope and the distance between doorframe at the top of doorframe.
Further, a kind of elevator runs collision prevention device up and down, and the electric limiting switch is fixed at shield
Below column, the electric limiting switch is lead limit switch.
Further, a kind of elevator runs collision prevention device up and down, and the counterweight is metal derby.
Further, a kind of elevator runs collision prevention device up and down, and there are four the idler wheel settings, is separately positioned on
The end of square tube.
A kind of elevator provided by the utility model runs collision prevention device up and down, and in use, elevator is upper
Lower operation, when there are foreign objects to stretch out floor, stops that it runs channel, overhanging object can make the path locus of steel wire rope occur
Variation, that is, when stretching or compressing steel wire rope, free end steel wire rope can pull counterweight up to move, and to touch electric limiting, make
It is acted, and elevator is out of service.When relieving foreign object compression or stretching steel wire rope, under the weight condition of counterweight so that
Steel wire rope restores original path, while counterweight leaves electric limiting position, and elevator restores normal.
The beneficial effects of the utility model are：The device can carry out the interferences within the scope of lift trunk advance
Detection completes being automatically stopped for elevator, avoids liter when there is interferences to stop elevator by the buffer structure of the device
Drop machine damages and casualties, and when object is interfered in discharge, elevator can then restore normal operation, improves equipment operation
Safety.
