Description

The method of installing the lower suspended steel structure by pulling the hanging basket by the winch

technical field

The invention relates to the field of high-altitude steel structure construction, in particular to a method for installing a lower suspended steel structure by pulling a hoisting basket through a hoist.

Background technique

As one of the most common working platforms for high-altitude steel structures, the working basket/hanging cage has the characteristics of simple production, easy operation and strong practicability. However, when the position of the hanging basket needs to be adjusted during the installation of the steel structure, the horizontal and vertical adjustment at height is usually performed by manpower. In addition, the installation work of the lower suspended steel structure, especially the high-altitude corridor structure, the cantilever structure and the hanging structure of the lower part of the main structure of the large-span workshop, involves a lot of high-altitude operations. In such cases, the use of a gondola is the only but high-risk method.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the above-mentioned defects, and to propose a method for carrying out the construction work of the suspended steel structure through the hanging basket, which is convenient and safe to operate.

In order to achieve the above object, the present invention is achieved in this way:

A method for installing and operating a lower suspended steel structure by pulling a hanging basket by a hoist, comprising a hanging basket, a hoisting device, a pulley block, a traction wire rope, a limit steel bar for the hanging basket, and a spare hanging rope; it also includes the following steps:

Step 1. Connect the pulley block to the completed structure stably and firmly. The hoisting equipment is equipped with a special person to operate the synchronous switch, and the gondola and the traction wire rope are limited by the gondola limit steel bars;

Step 2. A spare sling is also set on the hanging basket, and both ends of the spare sling are firmly tied to both ends of the completed structure;

Step 3. Adjust the length of the spare sling. When the traction wire rope is working normally, the spare sling will not be stressed. When the traction wire rope is broken due to external force or damage, the backup sling will be protected by force to prevent the basket from falling;

Step 4. A lifeline should be set on the main structure above the gondola, and safety ropes must be hung when personnel work in the gondola to form double protection;

Step 5. Connect the hanging baskets in series through the hoisting equipment, the pulley block, and the traction wire rope, so as to form a form of movement of the hanging basket driven by the hoisting equipment, the pulley block transmission, and the traction wire rope, so as to achieve the purpose of operating the lower suspended steel structure.

The invention proposes an operation mode of the hanging basket for high-altitude work, which consists of the traditional hanging basket, the hoisting equipment and the directional pulley block as a whole, and the tractive action of the hoisting equipment is used to complete the aerial movement of the operating hanging basket, thereby reducing the high-altitude operation of the operator. Move risks, improve work efficiency at heights, and save temporary measures such as construction walkways.

Detailed ways

The present invention is further illustrated by specific examples below.

As shown in Figures 1 and 2, a method for installing a lower suspended steel structure by pulling a hanging basket by a hoist includes a hanging basket 1, a hoisting device 2, a pulley block 3, a traction wire rope 4, and a hanging basket limit steel bar 5 , the spare hanging rope 6; also includes the following steps:

Step 1. Connect the pulley block 3 to the completed structure stably and firmly. The hoisting equipment 2 is equipped with a special person to operate the synchronous switch, and the gondola 1 and the traction wire rope 4 are limited by the gondola limit steel bar 5;

Step 2. A spare hanging rope 6 is also set on the hanging basket 1, and both ends of the spare hanging rope 6 are firmly tied to the two ends of the completed structure;

Step 3. Adjust the length of the spare sling. When the traction wire rope is working normally, the spare sling will not be stressed. When the traction wire rope is broken due to external force or damage, the backup sling will be protected by force to prevent the gondola 1 from falling;

Step 4. The upper main structure of the gondola 1 should be provided with a lifeline, and personnel must hang a safety rope when entering the gondola 1 to work to form double protection;

Step 5. Connect the gondolas 1 in series through the hoisting equipment 2, the pulley block 3 and the traction wire rope 4, so as to form a moving form of the gondola 1 driven by the hoisting equipment 2, driven by the pulley block 3, and pulled by the traction wire rope 4, so as to realize the downward movement. The purpose of working on suspended steel structures.

The invention proposes an operation mode of the hanging basket for high-altitude work, which consists of the traditional hanging basket, the hoisting equipment and the directional pulley block as a whole, and the tractive action of the hoisting equipment is used to complete the aerial movement of the operating hanging basket, thereby reducing the high-altitude operation of the operator. Move risks, improve work efficiency at heights, and save temporary measures such as construction walkways.
