Problems solved by technology

At present, the traditional inspection methods for bridges mainly include scaffolding, hanging baskets and bridge inspection vehicles. The operation efficiency of bridge crack detection by building scaffolding is low. There are potential safety hazards, and the bridge inspection vehicle will occupy the lane during operation and hinder traffic. Therefore, it is an urgent problem to invent a crack detection vehicle that can realize remote control.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] Such as figure 1 As shown, the bridge crack detection device of the present invention includes a cable special vehicle 5 and a crack detection trolley 6. The cable special vehicle 5 is installed on both sides of the bridge, and the railing 4 of the bridge is used as a moving track, and the load-bearing cables 1 and 3 are simultaneously drawn out as cracks. The motion track of the inspection trolley 6 is drawn, and the traction cable 2 is drawn to provide power for the crack detection trolley.

[0025] Such as Figure 2-5 As shown, the cable car 5 includes a cable car frame 5-2, a support 5-1, a support lifting mechanism, a support telescopic mechanism, a load-bearing cable contraction device, and a traction cable moving device. The rear end of the support 5-1 is connected to the support telescopic mechanism, and the support telescopic mechanism is connected to ...

Abstract

The present invention relates to a bridge crack detection device. The device comprises cable special vehicles and a crack detection dolly, the cable special vehicles are installed at two sides of a bridge, a handrail of the bridge is taken as a movement track, is connected with the crack detection dolly through two bearing cables to take as the movement track of the crack detection dolly, and is connected with the crack detection dolly through a traction cable to supply power to the crack detection dolly; the crack detection dolly comprises a dolly rack, an industrial control machine, a data collection device, a workbench moving mechanism, a ladder stand wheel and a bearing cable clamping device. The dolly rack is provided with the data collection device to achieve data collection of the bridge and storage the data in the industrial control machine and transmit the data to a data processing center through a RS485 network so as to achieve automatic collection and analysis of the cracks.The bridge crack detection device is simple, efficient and low in cost, and has no influence on bridge traffic.

Description

technical field [0001] The invention relates to a bridge crack detection device. Specifically, a CMOS camera is used to collect data on bridge cracks, and an auxiliary mechanical mechanism transmits the collected data to a data processing center through an RS485 network, belonging to a mechanical detection device. Background technique [0002] Regular inspection of bridges is helpful to understand the service status of bridges, and it is helpful to ensure the safety of bridges during their service period by formulating reasonable maintenance plans. At present, the traditional inspection methods for bridges mainly include scaffolding, hanging baskets and bridge inspection vehicles. The operation efficiency of bridge crack detection by building scaffolding is low. There are potential safety hazards, and the bridge inspection vehicle will occupy the lane during operation and hinder traffic. Therefore, it is an urgent problem to invent a crack detection vehicle that can realize ...
