Abstract

The invention discloses a hoistway elevator for construction. The hoistway elevator comprises a building hoistway, a sky beam, a traction medium, a traction machine, a cage and a counterweight; the sky beam is connected to the top end of the building hoistway, and the traction machine is connected to the lower portion of the building hoistway; and the sky beam is fixedly connected with a friction wheel and is rotatably connected with a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel, one end of the traction medium is connected to one end of the sky beam, and the traction medium sequentially bypasses the friction wheel, the cage, the second guide wheel, the third guide wheel, a driving wheel of the traction machine, the fourth guide wheel, the fifth guide wheel and the counterweight from the end until the other end of the traction medium is connected to the bottom face of the other end of the sky beam. According to the hoistway elevator for construction, the plurality of guide wheels and the traction medium are adopted to enable the cage to be located at a movable pulley, so that the traction capacity of the traction machine is doubled, the traction efficiency is improved, and the operation safety of the elevator is improved.

Description

technical field

[0001] The invention relates to the field of construction elevators, in particular to a hoistway elevator for construction. 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. 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 traction capacity of the existing traction machine can only double lift the car, and the lifting efficiency is low. In addition, the car often shakes and runs unstable du...
