Problems solved by technology

In the past, there were similar equipment in foreign countries, but due to the high price and incomplete functions, the developers made up their minds to develop domestic equipment. The wire machine and its winding method have been successfully applied to the construction of many large suspension bridges in China

Embodiment Construction

[0051] Referring to Figure 1a, b, the main wire winding machine is composed of four parts: the main machine, the front and rear clamping frames, and the guide beam.

[0052] The functions and principles of each institution are described as follows:

[0053] (1) Main engine: The frame 1 of the main engine is a door-shaped lower opening frame, which is formed by tailor-welding of section steel and steel plate. On its crossbeam and front column, large ring gear rollers are installed; four sets of clamping mechanisms 7 are installed on its side columns; In order to reduce the center of gravity, a hydraulic pump station 5 and a tool box are installed below the frame both sides.

[0054] There is a tie rod under the column of the corresponding clamping point at the opening of the frame. When you want to clamp the main engine, you should install the tie bar first and then clamp the main engine on the main cable 11. After loosening the main engine clamping mechanism, you should remov...

Abstract

A main cable wire wrapping machine and a wrapping method thereof relate to a device which can densely wrap galvanized mild steel wires on the main cables of a suspension bridge and a winding method thereof. The main cable wire wrapping machine is composed of a main machine, front and rear clamping holders and a guide girder. In the wrapping method, the wire wrapping of the main cable is first carried out on the end of a cable clip, then the internode wire wrapping is carried out, the wire wrapping of the main cable is carried out on the end of a terminal cable clip, a gear ring passes the cable clip, and finally the wire wrapping of the end of a second internode initiating terminal is prepared. The main machine of the present invention and the clamping holders can alternately travel on the main cable; the rotary speed and travelling speed of the main machine can be stepless regulated, matching is accurate and the main machine can carry out dense wire wrapping; the rotary gear ring is provided with a mobile gate, the cable clips and a suspension cable for convenient passing, and travelling wheels can automatically span the cable clips; applicable under different working conditions, the main cable wire wrapping machine has the advantages of stable and adjustable wire wrapping tension, convenient regulation, high wire wrapping efficiency and quality, easy operation, safety and reliability. The present invention is mainly used for forming a permanent protecting layer on the main cable by densely wrapping the galvanized mild steel wire on the main cable after the main cable is treated by antisepsis process at the last stage of the construction of the suspension bridge, so that the service life of the main cables is prolonged.

Description

technical field [0001] The invention relates to a device for densely winding galvanized soft steel wire on a main cable of a suspension bridge and a wire winding method thereof. Background technique [0002] Suspension bridges are in line with the development direction of modern bridges with large spans, heavy loads, and beautiful appearance. Since the main cable is the main structure of the suspension bridge, its protection is particularly important. The traditional method of main cable protection is to apply non-drying anti-corrosion paste first, and then wrap the wire in dense turns , and finally paint. Therefore, the main cable winding machine is the main special equipment for the installation and construction of the suspension bridge. In the past, there were similar equipment in foreign countries, but due to the high price and incomplete functions, the developers made up their minds to develop domestic equipment. The wire machine and its winding method have been succe...
