Problems solved by technology

[0003] The truss-type bridge inspection vehicle has a large horizontal detection range, high detection efficiency and good safety, but the vertical detection depth is small, the bridge adaptability is poor, and the detection ability of cable-stayed bridges, suspension bridges, combined steel structure bridges and large-depth piers is limited; The horizontal detection range and vertical detection depth of the folding bridge inspection vehicle are large, and the bridge adaptability is strong, but the detection efficiency and safety are low
Due to the limitation of the working arm structure of the existing bridge inspection vehicle, it is difficult to achieve the unity of comprehensive performance such as detection range, detection efficiency, bridge adaptability and safety.

Embodiment 1

[0025] Such as Figure 1-4 As shown, a bridge inspection vehicle with a mixed working arm includes a chassis 2 and a working arm. The lower front end of the chassis 2 is provided with a crawler-type auxiliary support 1. The working arm is composed of a box girder part and a truss part.

[0026] In the box beam part, the lower end of the slewing support arm 3 is connected to the chassis 2, the upper end of the slewing support arm 2 is hinged with one end of the main arm 5, the lower end of the side of the slewing support arm 2 is hinged with one end of the main arm hydraulic cylinder I4, and the main arm hydraulic cylinder I4 is hinged. The other end of the main arm is hinged with the main arm 5, the other end of the main arm 5 is hinged with the upper end of the rotary center 7, the two ends of the main arm hydraulic cylinder II6 are respectively hinged with the main arm 5 and the rotary center 7, the lower end of the rotary center 7 is connected with the The upper end of the ...

Embodiment 2

[0033] As another embodiment of the present invention such as figure 2 As shown, the vertical arm hydraulic cylinder II 11 drives the truss working platform 14 to lower, the fixing member 17 fixes the lifting guide rail 18 and the hanging basket 19, the lifting and leveling hydraulic cylinder 16 drives the hanging basket to rotate relative to the truss working platform 14, and the hanging basket 19 keeps level, which has met the requirements of large-depth detection operations on bridge piers, etc.

Abstract

The invention discloses a novel hybrid bridge detection vehicle. The novel hybrid bridge detection vehicle comprises a working arm, wherein the working arm comprises a box girder, a truss working platform and a swinging scaffold, wherein one end of the box girder is connected to the truss working platform through a lapping frame while the other end of the box girder is connected to a chassis; and one end of the truss working platform is connected to the box girder while the other end of the truss working platform is connected to the swing scaffold. By adopting the working arm in the new structural form, the comprehensive performances of the bridge detection vehicle are improved, and uniformity of detection amplitude, detection efficiency, bridge adaptability, safety and the like is realized.

Description

technical field [0001] The invention relates to a bridge inspection vehicle, in particular to a novel hybrid bridge inspection vehicle. Background technique [0002] The bridge inspection vehicle is used in conjunction with the inspection and maintenance of bridges. It can safely and efficiently send maintenance personnel to work below the bridge deck. It is expensive due to its large size and complex technology. The main performances of the evaluation bridge inspection vehicle include detection range, detection efficiency, bridge adaptability and safety. The working arm of the bridge inspection vehicle is the key component to ensure its performance. According to the different structural forms of the working arm, the bridge inspection vehicle can be divided into three types: truss type, folding type and hybrid type. [0003] The truss-type bridge inspection vehicle has a large horizontal detection range, high detection efficiency and good safety, but the vertical detection ...
