Background

The elevator belongs to special equipment, and the operation and maintenance personnel of the elevator need to hold special equipment operating personnel certificates.

Elevators are becoming more and more popular as an mechatronic device and are used more frequently, with the attendant occurrence of elevator faults more frequently. For the elevator without a machine room, because the traction main machine, the speed limiter and other components are arranged in the elevator shaft, when a fault occurs and emergency rescue is needed, the emergency rescue cannot be realized through turning a car due to the structural limitation, and the emergency rescue work can be finished only in a brake releasing mode. However, when the elevator without the machine room breaks down and stops in the non-door-opening area, and some more extreme working conditions occur, such as: (1) the weight of the car is equal to that of the counterweight or the speed governor and the safety gear are linked, so that the car cannot move when the brake is released; (2) the car falls down reversely after rushing to top, so that the safety tongs act, and the car can move with a small stroke after being released, so that the safety tongs cannot be reset; (3) under the conditions that the manual brake release device fails to release the brake and the like, common emergency rescue cannot be implemented, and the rescue difficulty is very high.

The utility model discloses a following scheme realizes: an elevator emergency rescue device comprises an upper clamping block, a lower clamping block and a lifting mechanism, wherein lifting lugs are arranged on the upper clamping block and the lower clamping block respectively, the upper clamping block is arranged at the upper end of a car steel wire rope, and the lower clamping block is arranged at the lower end of the car steel wire rope; the lifting mechanism upper end is provided with one and goes up the lifting hook, it colludes on the lug of last clamp splice to go up the lifting hook, be provided with the lifting hook down on the lug of clamp splice, the lifting hook passes through hoisting chain and is connected with lifting mechanism down, lifting mechanism is equipped with hand power chain, can drive hoisting chain and upwards promote through pulling hand power chain.

Furthermore, the upper clamping block and the lower clamping block have the same structure, the upper clamping block consists of an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are respectively provided with polygonal grooves which are matched with each other, the polygonal grooves are used for placing a car steel wire rope, the upper cover plate and the lower cover plate are respectively provided with through holes, and bolts penetrate through the through holes of the upper cover plate and the lower cover plate to fixedly clamp the upper cover plate and the lower cover plate on the car steel wire rope; the end part of the lower cover plate is provided with the lifting lug.

Furthermore, the lifting mechanism is a chain type chain block.

Furthermore, the lifting lug is a supporting plate, and a through hole is formed in the middle of the supporting plate.

Furthermore, the model of the chain type chain block is HS-C type chain block.

The beneficial effects of the utility model reside in that: the utility model discloses clamp splice is set up in car wire rope's upper end, car wire rope's lower extreme sets up down the clamp splice, go up the clamp splice and set up hoist mechanism down between the clamp splice, and be connected hoist mechanism with last clamp splice and lower clamp splice respectively through last lifting hook and lower lifting hook, when pulling hand power chain, lower lifting hook promotes down the clamp splice, make it produce relative motion with clamp splice down to go up the clamp splice, thereby promote the upward movement of car, the operation is very simple, like this under elevator emergency, can carry out emergency rescue, the efficiency of rescue is improved.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the elevator emergency rescue device of the present invention includes an upper clamping block 1, a lower clamping block 2 and a hoisting mechanism 3, wherein the upper clamping block 1 and the lower clamping block 2 are both provided with a lifting lug 11, the upper clamping block 1 is arranged at the upper end of a car steel wire rope 4, and the lower clamping block 2 is arranged at the lower end of the car steel wire rope 4; lifting mechanism 3 upper end is provided with one and goes up lifting hook 5, it colludes to go up lifting hook 5 go up on the lug 11 of clamp splice 1, be provided with lifting hook 6 down on the lug of clamp splice 1, lifting hook 6 is connected with lifting mechanism 3 through hoisting chain 7 down, lifting mechanism 3 is equipped with hand power chain 8, can drive hoisting chain 7 through pulling hand power chain 8 and up promote. And a hand-pulling chain and a hoisting chain are arranged on the lifting mechanism, and transmission is realized through multi-stage gear connection. Therefore, the lifting chain can be driven to lift upwards by pulling the hand-pulling chain. Because the upper lifting hook is connected with the upper clamping block, and the lower lifting hook is connected with the lower clamping block, when the hand-pulling chain is pulled, the lower lifting hook lifts the lower clamping block, so that the upper clamping block and the lower clamping block generate relative motion, the lift car moves upwards, and emergency rescue is realized.

As shown in fig. 3, the upper clamping block 1 and the lower clamping block 2 have the same structure, the upper clamping block 1 is composed of an upper cover plate 12 and a lower cover plate 13, the upper cover plate 12 and the lower cover plate 13 are respectively provided with polygonal grooves 14 which are matched with each other, the polygonal grooves 14 are used for placing the car steel wire ropes, and the polygonal grooves of the upper cover plate and the polygonal grooves of the lower cover plate are matched with each other so as to clamp the car steel wire ropes; the number of the polygonal grooves 14 is not limited, and generally 6-10 polygonal grooves are arranged according to actual conditions; the upper cover plate 12 and the lower cover plate 13 are respectively provided with through holes 15, wherein the number of the through holes 15 is not limited, and generally 8-10 through holes are arranged according to actual conditions; bolts 16 penetrate through holes 15 of the upper cover plate 12 and the lower cover plate 13 to fixedly clamp the upper cover plate 12 and the lower cover plate 13 on a car steel wire rope; the end part of the lower cover plate 13 is provided with the lifting lug 11.

The utility model discloses in, hoist mechanism 3 is chain type chain block. In practical application, the model of the chain type chain block is HS-C type chain block, and other models of chain blocks can be used; the lifting lug 11 is a supporting plate 111, and a through hole 112 is formed in the middle of the supporting plate. The upper hook 5 or the lower hook 6 is hooked on the through hole 112, and the support plate is fixed to the lower cover plate 13.

The utility model discloses a theory of operation does: after the elevator breaks down, modes such as wire rope are looked over through the urgent calling equipment inquiry or the computer lab in the elevator car, confirm the elevator concrete floor that stops that breaks down, professional arrives corresponding floor and opens the layer door and reach the sedan-chair top, and begin to implement the rescue), elevator car is located the below of flat zone layer this moment, then sets up clamp splice 1 in the upper end of car wire rope 4, clamp splice 2 sets up the lower extreme at car wire rope 4 down, goes up lifting hook 5 and colludes on the lug 11 of last clamp splice 1, lower lifting hook colludes on the lug of clamp splice down, can drive the jack-chain up through pulling hand chain and promote. Because the upper lifting hook is connected with the upper clamping block, and the lower lifting hook is connected with the lower clamping block, when the hand-pulling chain is pulled, the lower lifting hook lifts the lower clamping block, so that the upper clamping block and the lower clamping block generate relative motion, the lift car moves upwards, and emergency rescue is realized.
