Abstract
A lifting machine steel wire rope breakage-proof protection device is installed on cross beams of a lifting machine, the cross beams of the lifting machine are installed between a front column and a rear column in a sliding mode, a vehicle carrying plate of the lifting machine is installed between the two cross beams and used for driving steel wire ropes lifted by the cross beams to be installed in the cross beams. When the steel wire ropes break or drop, the lifting machine steel wire rope breakage-proof protection device can trigger guide wheels to break away from the steel wire ropes to enable a reset spring to pull a trigger rod, the trigger rod breaks away from a trigger device of a limiting switch, accordingly the limiting switch is triggered, a controller connected with the limiting switch controls the lifting machine to stop working, and dangers including device inclination, oil cylinder piston rod breakage, fall of vehicles on the vehicle carrying plate, lifting machine collapse and the like are prevented under the situation that the steel wire ropes break or drop. When the steel wire rope guide wheels enable the lifting machine to lift, the steel wire ropes move stably, the breakage-proof protection device is prevented from being triggered when the lifting machine works normally, and accordingly normal work of the lifting machine is prevented from being influenced.
Description
Technical field
The present invention relates to a kind of protective device, specifically, is a kind of steel wire rope fracture prevention protective device for lifting machine.
Background technology
Four current post lifting machines carry out lifting, all draw by oil cylinder the lifting that four wire rope carry out vehicle-containing, when vehicle-containing is elevated, if there is fracture or come off in wire rope, and operating personnel still carry out descending operation when not discovering, easily cause vehicle-containing deflection, cause device inclined, oil cylinder lateral force is excessive, causes cylinder piston rod to rupture, and the danger that vehicle drops, lifting machine collapses on vehicle-containing even occurs.
Summary of the invention
The danger that the present invention is directed to above-mentioned lifting machine wire cable rupture or easily cause after coming off, devises a kind of lifting machine steel wire rope fracture prevention protective device.
Lifting machine steel wire rope fracture prevention protective device of the present invention, be arranged on the crossbeam of lifting machine, the crossbeam of lifting machine is slidably mounted between former and later two columns, the vehicle-containing of lifting machine is arranged between adjacent two crossbeams, be arranged in crossbeam for driving the wire rope of beam lifting, described break-proof protecting device comprises the limit switch be arranged on crossbeam, frizzen, wire rope guide wheel, be coupling in the middle part of frizzen on crossbeam, the front end of frizzen is provided with triggering guide wheel, wire rope guide wheel is arranged on the rear of frizzen, wire rope is positioned at the race triggering guide wheel and wire rope guide wheel, between frizzen rear end and crossbeam, back-moving spring is installed, when break-proof protecting device is positioned at original state, back-moving spring is in the state be stretched, frizzen is also provided with the trigger board on the trigger being close to limit switch setting, limit switch is connected with the controller of lifting machine.
The invention has the beneficial effects as follows: lifting machine steel wire rope fracture prevention protective device can when wire rope fracture occurs or comes off; trigger the constraint that guide wheel departs from wire rope; back-moving spring is made to pull frizzen; trigger board is made to depart from the trigger of limit switch; thus triggering limit switch; make the controller be connected with limit switch control lifting machine to quit work; when preventing at wire cable rupture or come off, lifting machine work on cause device inclined, cylinder piston rod fracture, danger such as vehicle drops, lifting machine collapses on vehicle-containing.When wire rope guide wheel makes lifting machine be elevated, wire rope stable movement, triggers break-proof protecting device when avoiding lifting machine normally to work, affects the normal work of lifting machine.
Accompanying drawing explanation
Accompanying drawing 1 is the structure chart of lifting machine steel wire rope fracture prevention protective device.
Detailed description of the invention
Lifting machine steel wire rope fracture prevention protective device of the present invention, as shown in Figure 1, be arranged on the crossbeam 1 of lifting machine, the crossbeam 1 of lifting machine is slidably mounted between former and later two columns 2, the vehicle-containing 3 of lifting machine is arranged between adjacent two crossbeams 1, the wire rope 4 be elevated for driving crossbeam 1 is arranged in crossbeam 1, described break-proof protecting device comprises the limit switch 5 be arranged on crossbeam 1, frizzen 6, wire rope guide wheel 7, be coupling in the middle part of frizzen 6 on crossbeam 1, the front end of frizzen 6 is provided with triggers guide wheel 8, wire rope guide wheel 7 is arranged on the rear of frizzen 6, wire rope 4 is positioned at the race triggering guide wheel 8 and wire rope guide wheel 7, back-moving spring 9 is installed between frizzen 6 rear end and crossbeam 1, when break-proof protecting device is positioned at original state, back-moving spring 9 is in the state be stretched, frizzen 6 is also provided with the trigger board 11 on the trigger 10 being close to limit switch 5 setting, limit switch 5 is connected with the controller of lifting machine.
When wire rope 4 generation fracture or when coming off, trigger the constraint that guide wheel 8 departs from wire rope 4, the back-moving spring 9 be stretched reclaims, pull the rear end of frizzen 6, make the trigger board 11 be arranged on frizzen 6 depart from trigger 10, trigger limit switch 5, limit switch 5 is by the controller of coupled lifting machine, control lifting machine quits work, and prevents dangerous generation.
