A large-slope climbing walking mechanism of a winding inspection vehicle

Abstract

The invention relates to a large-slope climbing travelling mechanism for a top chord inspection vehicle. The large-slope climbing travelling mechanism for the top chord inspection vehicle comprises a travelling wheel assembly and a pin rack, the travelling wheel assembly comprises two front wheels, two rear wheels, a support frame, a drive shaft, a drive system and a pin gear, the two rear wheels are connected through the drive shaft, the drive system is installed at one end of the drive shaft, the pin gear is installed on the drive shaft, a converse hook wheel is installed downwards on each of the two sides of the middle part of the support frame, the pin rack comprises a plurality of pins and two vertical plates, the two vertical plates are vertically arranged in parallel and are both installed on a top chord cover plate of an arc bridge, the pins are horizontally installed between the two vertical plates at equal intervals, the pins are meshed with the pin gear, a flange part is arranged at the upper part of each of the two vertical plates, the two flange parts correspond to the two converse hook wheels respectively, the converse hook wheel is partially located on the lower side of the flange part. The large-slope climbing travelling mechanism for the top chord inspection vehicle fulfills the purposes of reducing the number of the top chord inspection vehicles and storing the inspection vehicles in a warehouse, and is favorable for solving the problem of maintenance of the inspection vehicle.

Description

technical field [0001] The invention relates to a traveling mechanism, in particular to a large-slope climbing traveling mechanism of a winding inspection vehicle. Background technique [0002] At present, the climbing and walking mechanisms used for the upper chord inspection vehicle of the steel truss arch bridge mainly include: one is to use the hydraulic cylinder to push the walking type, which has a strong climbing ability, but the walking speed is slow and the efficiency of the walking mechanism is extremely low; One is a multi-rubber wheel walking method based on a four-bar linkage mechanism, which can realize continuous walking, but its climbing ability is limited. Simultaneously, no matter adopting the inspection car of which of the above-mentioned running mechanisms, it will not be disassembled once it is installed without special circumstances. Because the working environment of the inspection car is relatively poor, the maintenance of the inspection car itself is...
