Special construction hoist in the shaft

Abstract

The invention discloses a special construction hoist in a hoistway. The special construction hoist comprises a main track, a sub track, a main track bracket, a sub track bracket, a traction machine, traction ropes, a lift car and a counterweight block, wherein the main track and the sub track are adjustably mounted on the inner wall of the hoistway through the main track bracket and the sub track bracket separately; the lift car moves up and down along the main track and the sub track; a main spandrel girder is arranged at the upper part of the hoistway; a traction wheel and a guide wheel are arranged on the spandrel girder; the lift car and the counterweight block are connected at the two ends of the traction ropes separately; the traction ropes are driven by the traction machine; the size of the lift car depends on the size of the hoistway; and the lift car can freely extend and retract between 1700 mm to 2200 mm. According to the special construction hoist, mounting is convenient; during mounting, positions of the main track bracket and the sub track bracket can be adjusted according to the size of the hoistway, and clearances between the hoistway wall and the main track and between the hoistway wall and the sub track are adjusted; the smaller the clearances are, the larger the size of the adopted lift car can be, and the more the cargo transported at a time is; and the space of the hoistway is fully utilized, labor intensity of construction personnel is greatly reduced, project progress is quickened, and working efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a special construction lift in a hoistway. Background technique [0002] Construction elevator, also known as construction elevator, is a kind of construction machinery that adopts gear, rack meshing or wire rope lifting method to make the car move vertically or inclined to transport construction personnel, tools, equipment and materials. It is handed over to other The lifting mechanism is stable, safe and reliable, no need to set up another machine room or shaft, and has the advantages of convenient disassembly and assembly, strong handling flexibility, etc. It is widely used, especially in reducing the labor intensity of construction personnel, speeding up the project progress, and improving work efficiency. role. [0003] However, the shafts of existing construction elevators are of different sizes, and there is still a large gap between the car and the inner wall of the shaft....

AI Technical Summary

Problems solved by technology

[0003] However, the shafts of existing construction elevators are of different sizes, and there is still a large gap between the car and the inner wall of the shaft. The construction elevator relies on guide rails to guide when in use, and the guide rails are installed in the shaft through guide rail brackets. The components used to fix the guide rail are installed on the well wall or the beam. It fixes the spatial position of the guide rail and withstands various actions from the guide rail. The transmission guide rail bracket generally adopts welding ribs to ensure its strength and rigidity. During installation, the guide rail bracket and the guide rail are fixed by welding, which is not adjustable. For a fixed-sized hoistway, only the car of the corresponding size can be used, and the space of the hoistway cannot be fully utilized.
