Abstract
The invention relates to a method for installing a lower suspended steel structure by pulling a hanging basket through a winch; comprises a hanging basket (1), a hoisting device (2), a pulley block (3), a traction steel wire rope (4) and hanging basket limiting steel bars (5); the method is characterized by further comprising the following steps: the pulley block (3) is stably and firmly connected with the finished structure, and the hanging basket (1) and the traction steel wire rope (4) are limited through hanging basket limiting steel bars (5); the hanging basket (1) driven by the hoisting equipment (2), driven by the pulley block (3) and pulled by the traction steel wire rope (4) moves, so that the purpose of operating the suspended steel structure is realized. The invention provides an operation mode of an aerial work hanging basket, which utilizes the traction effect of a hoisting device to finish the aerial movement of the aerial work hanging basket, reduces the aerial movement risk of operating personnel, improves the work efficiency of aerial work, saves temporary measures such as construction walkways and the like.
Description
Technical Field
The invention relates to the field of construction of high-altitude steel structures, in particular to a method for installing a lower suspended steel structure by pulling a hanging basket through a winch.
Background
The operation hanging basket/cage is one of the most common operation platforms in steel structure high altitude, and has the characteristics of simple manufacture, convenient operation, strong practicability and the like. But when needing to adjust the hanging flower basket position among the steel construction installation, carry out high altitude level and vertical adjustment through the human action usually, such mode is wasted time and energy and there is the big problem of high altitude construction safety risk. In addition, the installation work of the lower suspended steel structure, in particular to the overhead corridor structure, the cantilever structure and the hanging structure at the lower part of the main structure of the large-span factory building, relates to a large amount of overhead work. In such cases, the use of baskets is the only but high-risk method.
Disclosure of Invention
The invention aims to overcome the defects and provides a method for performing suspended steel structure construction operation through a hanging basket, which is convenient and safe to operate.
In order to achieve the above object, the present invention is realized by:
a method for installing a lower suspended steel structure by pulling a hanging basket through a winch comprises the hanging basket, a winch device, a pulley block, a pulling steel wire rope, hanging basket limiting steel bars and a standby lifting rope; also comprises the following steps:
step 1, stably and firmly connecting a pulley block with a finished structure, arranging a special person for synchronous switch operation on a hoisting device, and limiting a hanging basket and a traction steel wire rope through hanging basket limiting steel bars;
step 2, arranging a spare lifting rope at the same time of the hanging basket, and firmly binding two ends of the spare lifting rope at two ends of the finished structure;
step 3, adjusting the length of the standby lifting rope, wherein the standby lifting rope is not stressed when the traction steel wire rope works normally, and the standby lifting rope is stressed to play a protective role when the traction steel wire rope is broken due to external force or damage, so that the hanging basket is prevented from falling;
step 4, arranging a life line on the main structure above the hanging basket, and hanging a safety rope when personnel enter the hanging basket for operation so as to form double protection;
and 5, serially connecting the hanging baskets through the hoisting equipment, the pulley block and the traction steel wire rope to form a hanging basket moving mode driven by the hoisting equipment, driven by the pulley block and pulled by the traction steel wire rope, so that the aim of operating the lower suspended steel structure is fulfilled.
The invention provides an operation mode of an aerial work hanging basket, which is characterized in that the traditional hanging basket, a hoisting device and a directional pulley block form a whole, the aerial movement of the work hanging basket is completed by utilizing the traction effect of the hoisting device, the aerial movement risk of operators is reduced, the aerial work efficiency is improved, and temporary measures such as construction walkways and the like are saved.
