Heavy air pipe elevator

Abstract

The invention discloses a heavy air pipe elevator which comprises a base (1), a vertical rod (2) installed on the base (1), a driving motor (4) installed on the vertical rod (2), a platform (3) capable of sliding up and down along the vertical rod (2), a fixed pulley fixed to the upper portion of the vertical rod (2), a pulley block fixed to the platform (3), and a steel wire rope, one end of the steel wire rope is fixed on a rotating shaft of the driving motor (4), the other end of the steel wire rope penetrates through the fixed pulley and the pulley block and is fixed on the platform (3), and the driving motor (4) is a forward and reverse rotation motor and is provided with a forward rotation button, a reverse rotation button and a stop button. According to the heavy air pipe elevator, the safety of air pipe installation is improved, and the air pipe is horizontally lifted, so that the air pipe installation is more convenient, and the air pipe is more controllable.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a heavy air duct hoist. Background technique [0002] In modern buildings, the proportion of large buildings and super high-rise buildings is gradually increasing, and the fire ventilation system of vertical ducts is more and more used in buildings. However, the installation of vertical air ducts in construction still fails to form an efficient and safe construction process. [0003] In the prior art, during the construction process of inspecting the air duct, some workers first lift the air duct onto the scaffolding, and then lift two people on the scaffolding to fix the height. It is difficult to install the air duct by the third or fourth person, especially the lifting of the air duct is difficult, inconvenient to install, and requires more personnel. At least four people are required for construction, or it is higher than the position required for the hoisti...

AI Technical Summary

Problems solved by technology

The third or fourth person to install, the air duct installation is more difficult, especially the air duct is more difficult to lift, it is not convenient to install, there are more personnel requirements, at least four people are required for construction, or it is higher than the position required for the installation of the air duct hoisting Workers make large adjustments, and many people are required to adjust the air ducts higher than the hoisting. Although part of the manpower is converted into electricity, it has not completely liberated all the manpower required for the air ducts before installation.

[0004] Even if mechanical lifting is used, such as chain-down hoisting, the hoisting speed is slow and safety issues cannot be guaranteed; or hoists are hoisted, but the hoist has no non-return device during hoisting, the safety factor is poor, and there is a greater safety hazard. risk
