Problems solved by technology
According to foreign surveys and relevant data, the box-shaped track beams of the current suspended monorail transportation system are mainly inspected by manual inspection. It is difficult to detect
At the same time, it is difficult to confirm the specific mileage position of the internal disease point when testing the inside of the box track beam
For the detection of cracks on the inner wall of box-type track beams, corrosion detection, boundary inspection and flatness of running surfaces, it is difficult to meet the detection of the operational safety and reliability of box-type track beams in suspended monorail systems by relying solely on manual visual inspection.

Embodiment Construction
[0019] see figure 2 .
[0020] The inspection device of the present invention includes a mobile platform (trolley), which can move in a specific environment inside the box-shaped track beam, thereby completing the detection of the track beam of the whole line.
[0021] A camera module, a red line laser module, a system control unit, a data acquisition storage unit, a data processing unit, a communication module, a radio frequency identification module and a power supply module are installed on the mobile platform.
[0022] The camera module is mainly composed of a camera and a light source. There are 5 cameras in total, which are used to take pictures of the internal structure of the box-shaped track beam and then store them through the data storage module of the data acquisition and storage unit. Considering that the light inside the box-shaped track beam is dark, a light source is needed to supplement it.
[0023] The red line laser module is composed of one-line lasers (...

The invention relates to a suspension monorail case-type beam inspection tour apparatus, which belongs to the technical of traffic engineering. The beam inspection tour apparatus comprises a moving platform and the following functional units arranged on the moving platform, five optical detection units which respectively correspond to five positions of a left track, a right track, an end face of a case-type track beam inner wall and two side surfaces; a system control unit, a system memory unit, a data processing unit, a communication unit and a radio frequency identification unit; wherein the radio frequency identification unit, the optical detection unit, the system memory unit, the data processing unit and the communication unit are respectively connected with the system control unit, and the system memory unit is connected with the data processing unit. The suspension monorail case-type beam inspection tour apparatus can help even substitute artificial inspection tour for crack detection, corrosion detection, gauge inspection and moving surface flatness detection.
Description
technical field [0001] The present invention relates to traffic engineering technology. Background technique [0002] At present, the suspended monorail transportation system is gradually rising in our country. As a new type of transportation system, the suspended monorail transportation system has the characteristics of less investment, short construction period, mature technology, safety and reliability, energy saving, environmental protection and no noise. It is a low-investment solution to urban Effective solution to traffic congestion and pollution problems. [0003] The track girder of the suspended monorail system generally adopts a simply supported steel box girder structure. It is supported in an open steel box; power and communication systems are installed inside the steel box. The cross-section of the box track beam is shown as figure 1 . [0004] As the main structure of the suspended monorail system, the box-shaped track beam needs to be regularly maintained...
