Bridge detection device

Abstract

The invention discloses a bridge detection device. The device comprises a bridge main body; a movable frame is arranged on one side above the bridge main body; idler wheels are arranged below the corners of the movable frame; a row of sliding rails are arranged on the two sides below the movable frame at equal intervals; a connecting frame is clamped at the bottom between two adjacent sliding rails; a connecting plate is fixedly connected to the top of one side of the movable frame; connecting rods are connected to the two sides of one side of the bottom end of the connecting plate; a bearingplate is connected to the bottom ends of the two connecting rods; a working platform is arranged above the bearing plate; stand columns are slidably connected into inner cavities of the sliding grooves in a penetrating and inserting mode; and a net bag is arranged between two adjacent stand columns. By means of the arrangement mode that the idler wheels and the sliding rails are matched, the working platform is driven by the connecting rods to move, so that the relative position of the working platform and a bridge is adjusted and changed in one dimension, and workers on the escalator are protected to a certain degree through matching of the net bag and the stand columns.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a bridge detection device. Background technique [0002] With the development of transportation, the development of bridge construction, which is an important part of transportation, is advancing by leaps and bounds. In order to ensure the safety of traffic participants, after the bridge is completed and put into use, regular inspections must be carried out regularly. Routine inspection of bridges includes the inspection of the substructure of bridges. Periodic inspections of bridges are the conditions for assessing the health status of bridges, understanding and controlling the occurrence and development of bridge diseases, formulating reasonable maintenance plans, prolonging the service life of bridges and ensuring the safety of bridges in service. . The impact of bridge inspection vehicles on the safety of bridge inspection personnel, project cycle and traffic plays a decisi...

AI Technical Summary

Problems solved by technology

[0004] 1. The general shelf is fixed on the bridge, which makes the relative position of the platform and the bridge fixed, which makes the position of the platform unable to move in position. When it is necessary to measure other positions of the bridge, it is necessary to measure the shelf. Dismantling and then re-fixing the frame will bring a lot of trouble to the multi-directional inspection of the bridge:

[0005] 2. If the shelf is fixed on a crane or a testing vehicle, although the crane or testing vehicle can drive the platform to move, the stability of this moving method is low, and it is difficult to move in a straight line, so it will make the platform move Poor mobile stability;

[0006] 3. When inspecting bridges, the shape and thickness of various bridges are different, which makes the staff have to step on the ladder to inspect the bridge, but the height of the general platform is fixed , unable to protect the staff on the ladder, which will directly threaten the safety of the staff
