Hanger articulated bridge inspection vehicle

Abstract

The invention discloses a hanger articulated bridge inspection vehicle, belonging to bridge maintenance and construction equipment. The hanger articulated bridge inspection vehicle comprises a frame chassis (21), a suspension arm is a C-type hanger (25), the frame chassis (21) is articulated with the lower end of a pillar (23) by a longitudinal axis hinge (22) and a longitudinal axis, the upper end of the pillar (23) is articulated with the protruded end of an upper cross beam of the C-type hanger (25) by a transverse axis hinge (24) and a transverse axis, or the frame chassis (21) is articulated with the protruded end of the upper cross beam of the C-type hanger (25) by the longitudinal axis hinge (22) and the longitudinal axis, and the protruded end of a lower cross beam of the C-type hanger (25) is at least provided with a fixed point of a lifting rope (26) or a lifting rope extending-retracting device. According to the invention, the pulling force of the lifting rope (26) on an inspection platform (5) can be directly transferred to a bridge floor (2), therefore, the vehicle disclosed by the invention is small in overturning moment, light in structure and convenient to assemble and use, and can be erected on sidewalks on both sides of a bridge, so that the vehicle is especially suitable to be applied to the bottom detection and maintenance engineering of heavy traffic bridges.

Description

technical field [0001] The invention relates to a construction equipment for bridge detection and maintenance, in particular to a hanger articulated bridge maintenance vehicle which is erected on sidewalks on both sides of a bridge and can provide lifting points for a working platform for detection and maintenance on the bottom of the bridge. Background technique [0002] At present, a large number of bridge structures built in my country have entered a period of mass maintenance and maintenance. In order to have a comprehensive and objective understanding and evaluation of the current status of bridge use, structural testing is generally carried out first. If problems are found, the problematic parts need to be repaired. Carry out maintenance work. Because the bottom of the bridge is an air-facing surface, it is difficult for the staff to be in place. For the convenience of the structural inspection of the bottom of the bridge, there are special bridge inspection vehicles in...
