A combined cable hoisting and laying auxiliary device

Abstract

The invention discloses a combined cable hoisting and laying auxiliary device, which comprises a horizontal fixing component, a side fixing component, a steel cable fixing cross arm and an anti-sway fixing bracket, wherein the horizontal fixing component and the side fixing component are assembled into a trapezoidal structural frame; the anti-sway fixing bracket is fixed to the upper part of the trapezoidal structural frame and is located at one side of the side fixing component for fixing and hoisting a fixed pulley; the steel cable fixing cross arm is fixed to the top of the trapezoidal structural frame and located above the anti-sway fixing bracket for hoisting a steel cable. The combined cable hoisting and laying auxiliary device does not need the help of a ceiling structure as a fixing point, and eliminates the damage influence on a building. The hoisting frame is stable and reliable in design, can avoid hidden dangers such as collapse and the like, is not restricted by the sites,is fixed by a lateral fixing part, and is suitable for all installation sites. Regardless of a narrow cable well or an equipment-intensive equipment room, the hoisting frame is detachable and reusable, thereby reducing construction and installation cost. The combined cable hoisting and laying auxiliary device can be widely used.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, in particular to a combined cable hoisting and laying auxiliary device. Background technique [0002] In the prior art of high-rise power supply systems, cables are generally laid through cable shafts to meet the power supply requirements of high-rise buildings. Generally, expansion bolts and fixed hooks are implanted in the ceiling floor of the equipment room on the roof layer, and the vertical power cable is hoisted and laid by hoisting the steel wire rope through the fixed pulley. [0003] The prior art has at least the following disadvantages: [0004] 1. When the ceiling structure plate of the equipment room has high waterproof requirements, the behavior of implanting expansion bolts on the ceiling structure plate may damage the waterproof layer or even damage the floor, which will cause water seepage in the machine room, which will affect the equipment and make fu...

AI Technical Summary

Problems solved by technology

[0004] 1. When the ceiling structure plate of the equipment room has high waterproof requirements, the behavior of implanting expansion bolts on the ceiling structure plate may damage the waterproof layer or even damage the floor, which will cause water seepage in the machine room, which will affect the equipment and make future maintenance difficult. Increased costs

[0005] 2. When there are many pipelines crossing and covering the ceiling in some equipment rooms, it is impossible to lift and lay cables by fixing pulleys on the ceiling

[0006] 3. If the hoisting fixed points are not set in a standardized manner, there will be hidden dangers such as collapse during the hoisting of super high-rise buildings
