Cable laying equipment for urban rail transit

Abstract

The invention discloses cable laying equipment for urban rail transit. The equipment includes a tractor, the tractor is provided with a driving device used for driving the tractor to move, a supporting device used for supporting a cable reel, a pay-off device used for driving the cable reel to rotate and a guide device used for guiding the direction of a cable. Wherein the guide device comprises afirst-stage guide mechanism and a second-stage guide mechanism which are sequentially arranged, and a cable sequentially penetrates through the first-stage guide mechanism and the second-stage guidemechanism and then extends out of the side portion of the tractor in the process that the pay-off device drives the cable reel to rotate. According to the cable laying equipment for urban rail transit, automatic paying-off can be achieved, the paying-off speed is higher, and a large amount of manpower is not needed.

Description

technical field [0001] The invention relates to the technical field of rail transit construction, in particular to cable laying equipment for urban rail transit. Background technique [0002] Urban rail transit is the backbone of urban public transportation. It has the characteristics of energy saving, land saving, large transportation capacity, all-weather, no pollution (or less pollution) and safety. It is a green and environmentally friendly transportation system, especially suitable for large and medium-sized cities. Existing urban rail transit mainly includes subway system, light rail system, monorail system, tram, maglev system, automatic guided rail system and urban rapid rail system, among which the subway system saves surface space, has low noise and is not harmful to other transportation facilities. Small impact and other characteristics have gradually become the main force of urban rail transit and an important goal of urban construction and development. The subw...

AI Technical Summary

Problems solved by technology

Most of the existing subway cables are packaged and transported in cable reels, because the cable size is relatively large, so the weight of a single cable reel is usually about 6-7 tons, which makes it difficult to install the cables on the hanger. Most of them adopt the method of manual installation. Each section of cable needs at least 20 workers to line up one by one and lift them up at the same time to be able to install it smoothly. The speed is extremely slow and the consumption of human resources is serious.
