Abstract
The utility model discloses a safety net hanging device which comprises three groups of supporting components which are matched for use, wherein each supporting component comprises two vertically arranged supporting columns, an upper roof truss chord and a lower roof truss chord which are used for connecting the two supporting columns are respectively and horizontally arranged between the tops of the two supporting columns, pulley blocks are arranged on the tops of the supporting columns of two groups of adjacent supporting components, a traction mechanism is arranged on the lower roof truss chord of the other group of supporting components, the pulley blocks are connected with the traction mechanism through steel wire ropes, and the steel wire ropes extend downwards along the pulley blocks and are connected with a safety net. Compared with the traditional installation method, the method has the advantages of simple operation and fast construction progress; the tightness of the safety net is controlled by the winch, so that constructors do not need to go up high altitude repeatedly, the safety is high, and accidents are not easy to happen; the winch replaces manual pulling of the pulley, so that the cost is reduced; after the safety net is pulled up, the travelling crane can still freely pass below the safety net.
Description
Technical Field
The utility model belongs to the field of safety protection, and particularly relates to a safety net hanging device.
Background
In the construction of metallurgical industry plants, roofing structures are installed to erect safety nets in order to prevent workers from falling down tools or various building materials and workers themselves from falling down without attention or for other reasons during work. The safety net can guarantee worker's safety, also can reduce the danger of worker and pedestrian on the building site simultaneously, is important safety device in the factory building construction. The safety net is usually hung on a roof beam, and when the safety net is to be erected and dismantled, the safety net is hung on the roof beam, so that the safety net is complex in hanging operation, labor waste and low in working efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a safety net hanging device which is simple to operate and quick in construction progress compared with a traditional installation method.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a safety net is hung and is established device, includes the supporting component that three groups cooperation were used, and the supporting component includes the support column of two vertical settings, is provided with the roof truss upper chord and the roof truss lower chord of connecting two support columns between two support column tops respectively horizontally, and wherein the support column top of two sets of adjacent supporting components is equipped with the assembly pulley, is equipped with the traction mechanism on another group's support component's the roof truss lower chord, and the assembly pulley passes through wire rope with the traction mechanism to be connected, and wire rope is connected with the safety net along assembly pulley downwardly extending.
A plurality of connecting columns are arranged between the upper chord and the lower chord of the roof truss at equal intervals, the top of each connecting column of the two groups of supporting components provided with the pulley blocks is connected with an additional pulley block, the additional pulley block is connected with a traction mechanism through a steel wire rope, and the steel wire rope extends downwards along the additional pulley block and is connected with a safety net.
The traction device is a winch.
Compared with the prior art, the utility model has the beneficial effects that:
1. compared with the traditional installation method, the method is simple to operate and fast in construction progress.
2. The safety net is controlled to be loose and tight through the winch, so that constructors do not need to go up high altitude repeatedly, safety is high, and accidents are not easy to happen.
3. And the winch replaces manpower to pull the pulley, so that the cost is reduced.
4. After the safety net is pulled up, the travelling crane can still freely pass below the safety net.

A plurality of connecting columns are arranged between the upper string 3 and the lower string 4 of the roof truss at equal intervals, the tops of the connecting columns of the two groups of supporting components provided with the pulley blocks 5 are connected with the added pulley blocks 5, the added pulley blocks 5 are connected with the traction mechanism through steel wire ropes, and the steel wire ropes extend downwards along the added pulley blocks 5 and are connected with the safety net 1.
The installation method comprises the following steps:
step 1, placing a safety net 1 on the ground under a roof truss in advance.
And 2, climbing the upper chord 3 of the roof truss by a worker through a crawling ladder welded on the supporting column.
And 3, hanging 8 groups of pulley blocks 5 at the upper chord of a constructor, and arranging two coaxial winch drums 2 at the lower chord of the other span roof truss, wherein the two coaxial winch drums are divided into 4 areas for hanging 4 groups of pulleys.
And 4, connecting one ends of the steel wire ropes of all the pulley blocks 5 to the safety net 1, and connecting the other ends of the steel wire ropes to the winding drum 2 of the winch.
And 5, stopping the winch when the safety net 1 is lifted to a distance lower chord.
And 6, completing installation, starting the winch again after the construction is finished, and putting down the safety net 1.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is needless to say that the scope of the present invention is not limited by the above disclosure.
