Description

Cradle safety lock

The utility model belongs to the construction equipment field, particularly a kind of safety lock.

At present, aerial work basket adopts mechanical centrifugal trigger-type safety lock, is the centrifugal speed-limit device of a kind of machinery, and it can only exceed the speed limit to workplatform and descendingly play the safety guard-safeguard effect, and do not possess prevent from, manual lock rope function.

In view of the foregoing, the purpose of this utility model is to provide a kind of good looking appearance, compact conformation, and assembling, easy to maintenance, rigidity is stable, possesses the cradle safety lock of safety precautions such as preventing from, prevent disconnected rope and manual lock rope function.

The purpose of this utility model is achieved in that it is by backplate, cylinder, thru-bolt, roller, bearing, eccentric bushing, roller shaft, the hole back-up ring, shaft block ring, power plate, lock rope clamp piece, side plate, rope sling, reseting handle, extension spring, copper packing, clamp, pin, lock rope handle, rotating shaft, caging bolt, regulate bearing pin, fixed cover, central layer, stage clip, bearing pin, the axis of guide, skeleton, fulcrum, tilt lock rope rocker is formed, on the left side plate top rope sling is set, on its inside, be respectively by four power plates down, two lock rope clamp pieces, the parallelogram sturcutre that skeleton and bearing pin are formed, four power plates are fixed on the skeleton both sides with bearing pin and fulcrum respectively in pairs, fix with shaft block ring; Central layer is through between the stage clip, and an end is fixed in the circular hole of power plate, and an end is fixed in the U-lag of skeleton, and central layer can move in U-lag, and making the stage clip energy storage or release can; Two lock rope clamp pieces are fixed between the power plate with three rotating shafts and an axis of guide respectively, and two ends are fixed with shaft block ring; Top fulcrum one end and reseting handle are fixed with pin; Clamp and copper packing are fixed between the left side plate, and clamp one end links to each other with lock rope handle, and fixes with pin; Extension spring one end links to each other with clamp, and the other end links to each other with screw, works the effect of automatically reseting; Top is divided into the manual lock rope section; The bottom is divided into the tilt lock rope section; Safe steel wire penetrating rope sling, manual lock rope section lock rope clamp piece and tilt lock rope section lock rope clamp piece; Two tilt lock rope rockers place the left side plate both sides respectively, link to each other with fulcrum, the axis of guide, and the fulcrum two ends are fixed tilt lock rope rocker with nut; Tilt lock rope rocker one end is being fixed caging bolt and is being regulated bearing pin; The other end is made up of the targeting part of load cable; The load cable targeting part is fixed on roller shaft between the roller by bearing, and fixes with back-up ring with the hole; Backplate one end is fixed with nut and cylinder, thru-bolt, and the other end links to each other with roller shaft; The roller shaft two ends are supported with eccentric bushing, the tension force of scalable load cable pair roller.

Under the normal condition, stage clip is under the effect of tilt lock rope rocker, and energy storage finishes, and caging bolt withstands side plate, and safe steel rope is unimpeded in lock rope clamp piece inside, normally lifting of workplatform; The workplatform degree of dip reaches under the lock rope angle state; stage clip is under the effect of tilt lock rope rocker; release energy; because parallelogram connection-rod effect; the gap dwindles between the lock rope clamp piece, pins safe steel rope rapidly, and workplatform is reliably stopped; can not play the safety guard-safeguard effect from horizontal reset after the locking.

Under the normal condition, when workplatform arrives a certain position and need pin safe steel rope, conter clockwise turn lock rope handle, stage clip releases energy, and pins safe steel rope; Elder generation's rising one segment distance before workplatform rises or descends, cw turn reseting handle, clamp blocks power plate, the stage clip energy storage, safe steel rope is unimpeded in lock rope clamp piece inside, the normally lifting of back workplatform of unblanking.

The utility model mainly comprises manual lock rope and tilt lock rope two parts, and all by four power plates, two parallelogram sturcutres that lock rope clamp piece, skeleton and bearing pin are formed, the manual lock rope section connects lock rope handle and reseting handle.Good looking appearance, compact conformation, assembling, easy to maintenance, rigidity is stable, possesses safety precautions and manual lock rope functions such as preventing from, prevent disconnected rope, is applicable to the steel rope machine security protection of the aerial work basket and the similar high-rise working that are working rope.
