Bridge inspection and maintenance device

Abstract

The invention relates to a bridge inspection and maintenance device comprising a walking guidance beam (1) which is arranged along the extension direction of a bridge, an inspection channel (2) which is used for supporting maintenance personnel and equipment, a channel walking mechanism (3) which is used for driving the inspection channel (2) to move along the walking guidance beam (1), a channel rotating mechanism (4) which is used for rotating the inspection channel (2) from a position vertically extending with respect to the walking guidance beam (1) to a position being parallel to the walking guidance beam (1), a series of separated hanging mechanisms that are alternately arranged on corresponding beams of the bridge, and at least three supporting walking units (6). The distance between the farthest two hanging mechanisms among any three adjacent hanging mechanisms is less than the length of the walking guidance beam (1); each of the supporting walking units (6) is provided with a unit walking mechanism that is arranged on the walking guidance beam (1) in a walking manner, and is hung on the walking guidance beam (1). Comparing with the prior art, the bridge inspection and maintenance device reduces the building cost of bridges, and the bridge inspection and maintenance device is convenient to be popularized.

Description

technical field [0001] The invention relates to a bridge inspection and maintenance device, in particular to a continuous-span bridge inspection and maintenance device. Background technique [0002] Up to now, my country's high-speed rail has nearly 10,000 kilometers of operating mileage. Calculated according to the proportion of bridges accounting for 52% of the line, my country's high-speed rail bridges are about 5,000 kilometers long. As the substructure of the track, the bridge must have high ride comfort, high stability and high reliability in order to ensure the safety, stability and ride comfort requirements of high-speed operating conditions. Therefore, the inspection and maintenance of bridges is very important. [0003] The high-speed rail bridge inspection vehicle is a professional vehicle that can provide bridge inspection personnel with operating platforms and equipment for mobile inspection and maintenance. It has the characteristics of flexibility, fastness an...

Problems solved by technology

[0012] For this reason, the technical problem to be solved by the present invention lies in the problem that the trailer-type truss high-speed railway bridge inspection and maintenance vehicle cannot be installed and used without installing a special track, and thus proposes a bridge inspection and maintenance device that does not need to install a special track
