A crawler-type self-propelled main cable inspection vehicle

Abstract

The invention discloses a crawler-type self-traveling main cable inspection vehicle. The crawler-type self-traveling main cable inspection vehicle comprises a main stander, a traveling drive mechanism, a compression wheel pressure-maintaining system, overturning straining mechanisms, a basket lifting system, working platforms and a control system, wherein the main stander is of an n-shaped structure and arranged on a main cable, a plurality of overturning straining mechanisms are longitudinally arranged between bottom two sides of the main stander to form a temporary folding lower passage, and the compression wheel pressure-maintaining system is mounted on the main stander and pushes against the bottom of the main cable, so that sufficient pressure is maintained between the main stander and the main cable; the traveling drive mechanism is mounted on the main stander and drives the main stander to travel by traveling on the main cable; the basket lifting system is mounted below the main stander, the working platforms are respectively mounted at two outer sides of the main stander, and the control system is respectively connected with the traveling drive mechanism, the compression wheel pressure-maintaining system, the overturning straining mechanisms and the basket lifting system. By adopting the crawler-type self-propelling main cable inspection vehicle, an auxiliary suspension cable can be effectively bypassed, barrier-free continuous climbing can be realized, and safety and reliability can be realized.

Description

technical field [0001] The invention relates to a crawler-type self-propelled main cable inspection vehicle, in particular to a safe and reliable main cable inspection vehicle that automatically passes over a sling, and belongs to the technical field of inspection vehicles. Background technique [0002] In recent years, my country has carried out large-scale construction of suspension bridges and cable-stayed bridges, making my country the country with the largest number of suspension bridges and cable-stayed bridges, the largest span, and the largest investment in the world. [0003] Cables are the load-bearing components of suspension bridges and cable-stayed bridges, and they are the guarantee for the safety and reliability of bridges. At present, the inspection and maintenance of cables in our country are still done manually by operators at an altitude of hundreds of meters. . Working at heights increases the safety hazards and labor intensity of operators, and at the s...
