Sleeve rail type electric attachment lifting scaffold

Abstract

The invention discloses a sleeve rail type electric attachment lifting scaffold which is characterized in that: the structure of an electric lifting mechanism is as follows: a frame body lifting sliding sleeve groove is sleeved on a vertical guide rail frame and takes the vertical guide rail frame as a guide column; a frame body is fixedly connected with a frame body vertical main framework through a third connecting piece; the frame body vertical main framework is fixedly connected with the frame body lifting sliding sleeve groove through a first connecting piece; the vertical guide rail frame is fixedly connected with a building body beam by a first wall-through bolt through an attachment support structure; a toothed column or rack which is vertically arranged is mounted in a middle groove in front of the vertical guide rail frame; a frame body lifting drive device is mounted on the bottom structure of the frame body; and an output shaft of the frame body lifting drive device is meshed with the toothed column through a first gear on a first transmission shaft to form gear and toothed-column meshing transmission. In the whole using period from the time when the scaffold disclosed by the invention is put into use to the time when the construction is finished and the scaffold is dismantled, the fixation and connection of the frame body lifting drive device do not need to be changed, the using process is convenient, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a scaffold used in high-rise building construction engineering, in particular to a rail-mounted electric attachment lifting scaffold. Background technique [0002] In the prior art, the scaffolding used in the construction of high-rise buildings is a traditional double-row scaffolding built with steel pipes and fasteners. There are a lot of materials used, and it takes a lot of labor to erect and dismantle it. It takes a long time to transport the tower crane. The cost is high; the other is the attached lifting scaffold that has been put into use in recent years. The lifting power of the attached lifting scaffold is an electric chain hoist, and the hook of the electric chain hoist is hooked on the horizontal beam hanging structure of the frame. The electric chain hoist itself is hooked on the attached support structure. The dynamic and static parts of this type of attached lifting scaffold are fixedly connected. In use, the han...

[0002] In the prior art, the scaffolding used in the construction of high-rise buildings is a traditional double-row scaffolding built with steel pipes and fasteners. There are a lot of materials used, and it takes a lot of labor to erect and dismantle it. It takes a long time to transport the tower crane. The cost is high; the other is the attached lifting scaffold that has been put into use in recent years. The lifting power of the attached lifting scaffold is an electric chain hoist, and the hook of the electric chain hoist is hooked on the horizontal beam hanging structure of the frame. The electric chain hoist itself is hooked on the attached support structure. The dynamic and static parts of this type of attached lifting scaffold are fixedly connected. In use, the hanging point of the electric hoist hook must be replaced every time the frame is lifted. , that is, remove the electric hoist and replace the hooking point again to prepare for the next lifting of the frame body, and the electric hoist is still a hanging hoist in essence, which is prone to chain overturning and twisting, and is extremely inconvenient to use; this type of attachment Some of the vertical main frames used for anti-tilting and anti-falling of lifting frame scaffolding are made of single channel steel, and some are made of angle steel or I-beam. Due to their insufficient strength and rigidity, the functions of anti-tilting and anti-falling are not complete. After each lifting and lowering of the frame, the entire frame and the building must be re-anchored with steel wire ropes and steel pipes to prevent the frame from falling and toppling. Before the next lifting of the frame, the hook of the electric chain hoist After hanging, it is necessary to remove all the anchors made to the whole frame and the building. Although the attached lifting scaffold in the prior art has a simple structure, it has poor safety and is time-consuming and laborious to use. Convenient, but not easy to automate
