On-cable walking-type self-walking system

Abstract

The invention discloses an on-cable walking-type self-walking system which comprises a guide beam (100), a walking frame (300) which is arranged on the guide beam and can move on the guide beam, two supporting legs (200 and 400) which are arranged on two ends of the guide beam, a walking cylinder (500), a hydraulic system, and the like, wherein the front side and the back side of the lower part of the walking frame are provided with two sets of automatic cable clamping devices (310 and 320) which can form the support on a cable, the supporting legs are respectively provided with a lifting cylinder (310) which is vertically arranged, one end of each lifting cylinder is connected with a supporting leg outer sleeve (201) for fixing the guide beam, the other ends of the lifting cylinders are connected with supporting leg inner sleeves (204) for fixing automatic cable clamping devices (210 and 410), one end of the walking cylinder (500) is connected with the guide beam, and the other end of the walking cylinder (500) is connected with the walking frame. The on-cable walking-type self-walking system disclosed by the invention does not need to be additionally provided with drawing equipment, and accessories for mutually high-altitude disassembling, assembling and carrying cable-clamping hoops, and the like, and has the advantages of self-walking, high automation degree, quick walking speed, and high safety.

Description

Technical field [0001] The invention relates to a cable-walking self-propelled system, in particular to a walking system capable of self-propelling suspension bridge erection machines such as a cable-loaded crane, a cable tightening machine, and a wire wrapping machine on the main cable of the suspension bridge. Background technique [0002] With the rapid development of my country's national economy, the construction scale and speed of kilometer-level long-span suspension bridges continue to increase. put forward higher requirements. At present, the suspension bridge erection machinery cannot walk on the cable by itself. It needs additional traction equipment and auxiliary devices such as manual high-altitude dismantling, handling, and installation of cable clamping mechanisms to complete the walking on the main cable. Taking the special lifting equipment cable-mounted crane for the steel box girder of the suspension bridge as an example, there are mainly hoist-type and hyd...

AI Technical Summary

Problems solved by technology

Taking the special lifting equipment cable-mounted crane for the steel box girder of the suspension bridge as an example, there are mainly hoist-type and hydraulic-lift type cable-mounted cranes in my country, whether it is walking on the cable, whether it is walking on a wheel set or a fully hydraulic walking type. It needs the traction of hoist, traction jack and other equipment to move on the cable, and manually carry, dismantle and install auxiliary parts such as cable clamps and hoops repeatedly at high altitude to complete the fixation of the whole machine on the main cable, which will increase the cost and prolong the construction period. dangerous
