Embodiment Construction

[0040] refer to Figure 1-23 , a construction method for dismantling a large-span cable hoist adjacent to a railway business line according to the present invention will be described in detail.

[0041] A large-span cable crane demolition construction method adjacent to the railway business line is characterized in that it comprises the following steps:

[0042] Step 1: First remove the hoisting rope 1. Before removing the hoisting rope 1, move the cable hook 2 and the crane 3 to the inspection platform on the top of the near-end tower 4, and first connect the hoisting rope 1 to the near-end tower. The frame 4 is connected with a steel wire rope to prevent slipping, and the pulley block 6 matched with the hoisting rope 1 is removed, and then the hoisting rope 1 is connected with the hoisting rope of the first hoist at the top of the near-end tower frame 4, and the first hoist is a 5T hoist , to disconnect the hoisting rope 1 and the near-end tower 4 is to untie the steel wire...

Abstract

The present invention relates to a construction method for dismantling a cable crane, specifically a construction method for dismantling a large-span cable crane adjacent to a railway business line, which solves the technical problems in the background technology. The working rope 10 is dismantled step by step, and then the part above 100m of the super high-rise tower is dismantled by the shaking head 14; The whole floor is demolished. The present invention is specially aimed at dismantling large-span cable cranes on railway business lines with tight construction schedule and poor working environment. The super high-rise tower system is divided into three parts for dismantling. The demolition of parts is gradually adjusted to the demolition of the whole floor, which improves work efficiency and transfers a large number of high-altitude operations to the ground, which minimizes safety risks, reduces railway blockade points, and ensures the safety of railway operation lines.

Description

technical field [0001] The invention relates to a construction method for dismantling a cable crane, in particular to a construction method for dismantling a large-span cable crane adjacent to a railway business line. Background technique [0002] With the development of the economy and the improvement of environmental protection requirements, long-span steel pipe arch bridges have been used more and more when crossing large rivers, rivers, and deep valleys. The main construction of the steel pipe arch mainly relies on cable hoisting. [0003] The large-span cable crane for railway business lines mainly includes hoisting rope 1, traction rope, load-bearing rope 9 (main rope), crane 3, cable crane hook 2 and super high-rise tower system, such as figure 1 As shown, the super high-rise tower system includes a near-end tower 4 and a far-end tower 5; (its height exceeds 100m, which belongs to a super high-rise building), and the hoisting rope 1 is provided with a hook for adjusti...
