A bridge inspection vehicle with self-removable frame

Abstract

The invention discloses a bridge inspection vehicle with a self-detachable and replaceable frame, which includes a bottom plate, a weight block and a support column. First hydraulic cylinders are respectively arranged at the four corners of the top of the bottom plate, and the four first hydraulic cylinders are all fixedly arranged. On the top surface of the bottom plate, four through holes are opened on the bottom plate below the four first hydraulic cylinders, and four first piston rods are arranged inside the four first hydraulic cylinders. The bottom ends of the four through holes protrude from the bottom of the bottom plate respectively. When the frame needs to be replaced, the first piston rod inside the first hydraulic cylinder moves to make the sliding block of the detection frame and the bottom of the bottom platform move. There is no force in the vertical direction between the slide rails, and the inspection vehicle is controlled to move forward, so that the slider of the inspection frame is separated from the slide rail, and the slider on the new inspection frame enters the slide rail to complete the disassembly of the inspection frame. It is easy to replace the new inspection frame when changing jobs, and it does not need to be fixed by bolts. The replacement is simple and the replacement efficiency is improved.

Description

technical field [0001] The invention relates to the field of bridge inspection equipment, in particular to a bridge inspection vehicle with a self-removable and replaceable frame. Background technique [0002] Bridge detection is related to people's own safety. Some bridges have different degrees of damage. The main manifestations are: irregular cracks in the structure, concrete spalling and exposed reinforcement, water erosion of beams and pier cap beams, etc. These factors have seriously affected bridges. The safety and durability of the bridge inspection vehicles currently used are complex in structure, high in cost, and difficult to repair. [0003] The Chinese patent with the publication number CN106835974B discloses a bridge inspection vehicle's overturn frame and bridge inspection vehicle, wherein the bridge inspection vehicle's overturn frame includes a longitudinal beam, an upper beam and a lower beam, and the upper beam and the lower beam are respectively connected...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a bridge inspection vehicle with a self-detachable and replaceable frame to solve the problem that the currently used bridge inspection vehicle is large in size. , the horizontal occupation area is large; when the bridge inspection vehicle is not used, the workers need to bind the rope to perform the inspection in a suspended manner, which is too dangerous and inconvenient to detect; the existing inspection vehicle is difficult to detect the inner side of the bridge bottom surface, and manual inspection cannot be carried out ; It is not easy to replace the existing bridge inspection vehicle with a new inspection frame. When the frame is damaged, it cannot be used, and new inspection equipment needs to be replaced, which is a problem of high cost.
