Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present utility model provides a technical solution: a lifting scaffold for elevator hoistway overhaul comprises a bearing bottom plate 1, a driving mechanism and a reinforced retainer 14.
The lower surface of the bearing bottom plate 1 is provided with buffer supporting legs 5; the bearing bottom plate 1 is made of stainless steel materials, and the buffer supporting legs 5 are made of rubber or foaming plastic. The left side of the bearing bottom plate 1 is provided with an overhaul channel 2, and a fence 3 is arranged around the overhaul channel 2 and on the upper side of the bearing bottom plate 1. The side at loading floor 1 is offered to passageway 2, when reaching the destination position, in the elevator shaft is gone into from passageway 2, conveniently overhauls in the elevator shaft, and rail 3 encloses passageway 2, plays the effect of maintaining to the maintainer, avoids the maintainer to drop from passageway 2, when maintainer gets off from loading floor 1, stride across rail 3 can. The outer wall of the buffer supporting leg 5 is provided with a plurality of buffer folding concave grooves 6 in a circumferential direction. The buffer folding concave groove 6 is formed in the outer wall of the buffer supporting leg 5, so that the outer wall of the buffer folding concave groove 6 is thinner, when the upper side of the buffer supporting leg 5 is pressed down, the buffer folding concave groove 6 is tightened inwards, and accordingly the buffer supporting leg 5 is integrally lowered to buffer the bearing bottom plate 1 on the upper side. The middle part of the buffering supporting leg 5 is concaved and extends to the inner lower side of the buffering supporting leg 5 to form a hollow part 7, and an air outlet small hole 8 communicated with the hollow part 7 is formed in the lower side of the side wall of the buffering supporting leg 5. When the buffer supporting leg 5 bottoms out, the bearing bottom plate 1 continues to descend and presses down the buffer supporting leg 5, the buffer supporting leg 5 contracts, so that the space of the hollow part 7 is compressed, gas in the hollow part 7 is in a high-pressure state, high-pressure gas in the hollow part 7 leaks outwards from the air outlet small hole 8, and the air outlet is slower due to the small hole diameter of the air outlet small hole 8, so that a certain energy absorption effect can be achieved on the descent of the bearing bottom plate 1. Elastic protection lifting ropes 4 are arranged on two sides of the upper surface of the bearing bottom plate 1. Through the setting of elasticity protection lifting rope 4 for the upper end of elasticity protection lifting rope 4 hangs in the upside of elevator shaft, prevents that load floor 1 from accidentally falling, plays the effect of insurance.
The driving mechanism comprises a track groove 9 formed in the right side wall of the bearing bottom plate 1 and a driving motor 12 positioned on the right side of the lower surface of the bearing bottom plate 1, driving idler wheels 11 are rotatably connected to the two sides in the track groove 9 through rotating shafts 10, belt wheels 13 are connected to the output shaft of the driving motor 12 and the end part of one rotating shaft 10, and the two belt wheels 13 are connected through a belt; a rail pre-installed in the elevator shaft, on which rail the rail groove 9 can slide longitudinally. The driving motor 12 is a worm and gear type self-locking driving motor. The worm and gear type self-locking driving motor adopts the prior art, such as a worm and gear type three-phase asynchronous motor under MINPEAR brand, and the rotor of the driving motor 12 can not rotate automatically due to the characteristics of the worm and gear when the operation is stopped through the cooperation of the worm and gear at the output end, so that the self-locking effect is achieved.
One end of the reinforcing retainer 14 is connected to the upper surface of the load-bearing bottom plate 1, and the other end is connected to a slider 15. The slide 15 also has a corresponding rail in the elevator hoistway, on which rail the slide 15 can slide longitudinally. The sliding block 15 is rotationally connected with a supporting roller 16. The support roller 16 is provided to reduce friction between the slider 15 and the rail.
In operation, the slider 15 and the rail groove 9 are respectively connected with corresponding rails installed in the elevator shaft in advance. The upper end of the elastic protection lifting rope 4 is connected with the upper end of the elevator shaft (or the entrance and exit of the elevator shaft), so as to play a role in suspending the bearing bottom plate 1 and increase the installability.
When the maintenance personnel stand on the bearing bottom plate 1 and need to ascend or descend the bearing bottom plate 1, the driving motor 12 drives the rotating shaft 10 and the driving roller 11 to rotate through the transmission of the belt wheel 13, the friction action between the driving roller 11 and the rail drives the whole body to ascend or descend on the rail, in order to prevent the driving roller 11 from sliding between the driving roller 11 and the corresponding rail, the driving roller 11 can be designed into a gear, the outer wall of the corresponding rail is designed into a rack, and the driving roller 11 and the rail cannot slide down due to insufficient friction force through the cooperation of the gear and the rack.
When the bearing bottom plate 1 falls carelessly, the elastic protection lifting rope 4 is used for traction, the buffer supporting legs 5 are used for buffering at the lower side, and safety is guaranteed.
To sum up, this lift scaffold for elevator well overhauls, through actuating mechanism to the drive operation of loading board 1, make loading board 1 can rise and descend in the elevator shaft, alleviateed the manual work in the elevator shaft because of the intensity of labour that the climbing caused, through strengthening the cooperation effect of holder 14 and slider 15, whole to drawing to the loading board 1 from the upside, play the effect of steady support to loading board 1, set up in the elevator shaft be used for with track groove 9, slider 15 matched with slide rail, make loading board 1 can install.
