Abstract

The invention provides a cable unwinding reel for a suspension bridge. The cable unwinding reel for the suspension bridge aims to solve the problems that a main-cable installation cable reel of the prior art is low in speed, high in transportation cost, high in installation cost, long in installation time and low in working efficiency. The cable unwinding reel comprises a base, an outer sleeve, an inner sleeve, a first polygonal frame body and a plurality of reinforcing plates. The inner sleeve is inserted into the outer sleeve. The first polygonal frame body is sleeved on the outer sleeve. The reinforcing plates are arranged between the inner side wall of the first polygonal frame body and the outer side wall of the outer sleeve, wherein one end of each reinforcing plate is arranged on the inner side wall of the first polygonal frame body, and the other end of the reinforcing plate is arranged on the outer side wall of the outer sleeve. The inner sleeve is fixed on the base. The cable unwinding reel for the suspension bridge is used for construction of the suspension bridge.

Description

technical field [0001] The invention relates to a cable spreader for a suspension bridge. Background technique [0002] At present, the main cable of the suspension bridge is installed with a special cable reel. The unit strands of the main cable are coiled in the cable reel, and each unit strand is equipped with a customized cable reel. The cable reel needs to be erected on the vertical bracket during installation. , and the anchor head is pulled by the traction rope for erection. The disadvantages of this method are as follows: 1. Each unit cable strand needs to be equipped with a separate cable tray. Due to the large number of cable trays, each cable tray needs to be installed once during construction, and the installation progress is slow. 2. Since each unit cable strand is equipped with a cable tray, the transportation cost increases, the installation cost increases, and the construction cost increases. 3. Long installation time and low work efficiency. Contents of ...
