Description

A device for detecting cracks on the bottom surface of a bridge

technical field

The utility model relates to the field of bridge detection, in particular to a crack detection device on the bottom surface of a bridge.

Background technique

As a building erected on rivers, lakes and seas for vehicles and pedestrians to pass smoothly, the health of the bridge structure is extremely important to the safety of passing vehicles and pedestrians. The damage of bridges, especially the damage of concrete bridges, is at least 90% caused by cracks, so the detection of bridge cracks is very necessary. At present, the detection methods for bridge cracks at home and abroad are mainly manual detection. Manual detection requires a lot of manpower and material resources, and there will be subjective interference factors in the detection process. Due to fatigue and other reasons, certain negligence occurs, and the accuracy and efficiency are low; In addition, when detecting cracks on the bottom of the bridge, the staff need to go down to the bottom of the bridge in person, which is very dangerous. Therefore, it is very necessary to provide a device with simple structure, convenient operation, high detection accuracy and no need for workers to go down to the bottom surface of the bridge to detect cracks.

Utility model content

The purpose of this utility model is to solve the above-mentioned problems in the prior art, and provide a bridge bottom surface crack detection device with simple structure, high integration, strong stability, convenient operation, simple installation and maintenance, and comprehensive photography of the bridge bottom surface.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A device for detecting cracks on the bottom surface of a bridge, including a trolley and a display terminal, and a turntable arranged above the trolley, an "L"-shaped horizontal telescopic rod arranged in the middle of the turntable, one end of which is connected to the end of the horizontal telescopic rod and can be wound around A vertical telescopic rod that rotates on its central axis, a detection telescopic rod that is connected to the other end of the vertical telescopic rod and can rotate longitudinally around its own end, and a collection unit arranged at the end of the detection telescopic rod; the collection unit and the display The terminal is wirelessly connected, and the collection unit includes a camera, which is connected with the camera, a memory for storing the camera shooting information, and a wireless transmitter connected with the camera, and used for sending the camera shooting information back to the display terminal immediately.

Preferably, the horizontal telescopic rod is composed of at least three segments of telescopic rods.

Preferably, the camera is a dome camera.

Compared with the prior art, the utility model has the beneficial effects that: the utility model integrates the entire bridge bottom surface crack detection device into a trolley, which has a high degree of integration, a small footprint, simple operation and reusability, saving Manpower and material resources; the utility model uses each telescopic rod and its autobiography or longitudinal rotation, even if the bottom surface of the bridge is uneven or has a large range, the hemispherical camera can still fully capture the situation on the bottom surface of the bridge, and store and wirelessly Transmission, so that the ground staff can obtain the required data without personally observing the bottom of the bridge, on the one hand, it ensures the safety of the staff; exact situation. The device has strong stability, wide detection range, convenient operation, simple installation and maintenance, and is suitable for popularization and application.

detailed description

The utility model will be further described below in conjunction with the description of the drawings and the embodiments, and the mode of the utility model includes but not limited to the following embodiments.

The purpose of this embodiment is to provide a device for detecting cracks on the bottom surface of bridges. As shown in Figures 1 and 2, the device includes a trolley 1, and a trolley roller 6 is provided below the trolley 1 to facilitate pushing the trolley; the device also includes a set The turntable 2 above the trolley 1 and fixedly connected with it, one end is arranged in the middle of the turntable, and is an "L"-shaped horizontal telescopic rod 3, and one end is connected to the other end of the horizontal telescopic rod 3, and can rotate around its own central axis Vertical telescopic rod 4, connected with the other end of vertical telescopic rod 4, and the detection telescopic rod 5 that can rotate longitudinally around its end, and the collection unit that is arranged on detection telescopic rod 5 ends; Described vertical telescopic rod 4 When it rotates, it will drive the detection telescopic rod connected to its lower end to rotate horizontally around the 4 axes of the vertical telescopic rod;

The crack detection device on the bottom surface of the bridge also includes a display terminal wirelessly connected to the acquisition unit, for displaying the information transmitted back by the acquisition unit immediately; the acquisition unit includes a camera 8, and a memory and a wireless transmitter connected to the camera 8 respectively, The memory is used to store the information captured by the camera 8 as a backup for subsequent inquiries, and the wireless transmitter is used to send the information captured by the camera 8 back to the display terminal in real time, so that the staff can check the information in time, and deal with it accordingly.

Wherein, the horizontal telescopic rod 3 is composed of at least three telescopic rods; the camera 8 is a dome camera.

As shown in Figure 1, when the device of this embodiment is not working, its horizontal telescopic rod 3, vertical telescopic rod 4 and detection telescopic rod 5 are all in a contracted state, and the detection telescopic rod 4 rotates upwards and leans against the vertical telescopic rod 4 sides. This kind of setting can facilitate the installation, disassembly and maintenance of the device, and it can be placed somewhere when not in use, and the floor space is also small. When in use, the trolley 1 can be pushed to move to the desired position under the trolley roller 6, and transport and use are very convenient.

As shown in Figure 2, when using the device of this embodiment, the horizontal telescopic rod 3, the vertical telescopic rod 4 and the detection telescopic rod 5 can be stretched as required. If the bottom surface of the bridge 7 is flat, then only the detection telescopic rod 5 needs to be adjusted. To the horizontal position, expand the detection range by adjusting the expansion and contraction of the detection telescopic rod 5 and rotating the vertical telescopic rod 4; to the desired position.

This device can effectively avoid the time-consuming, omission or inaccurate inspection by the staff directly, and it can also effectively avoid the danger of the staff personally reaching the bottom of the bridge for inspection, and has strong stability, wide detection range and convenient operation , easy installation and maintenance, suitable for popularization and application.

The above-mentioned embodiment is only one of the preferred embodiments of the present utility model, and should not be used to limit the protection scope of the present utility model, but any modification or embellishment without substantive meaning made on the main design idea and spirit of the present utility model, If the technical problems it solves are still consistent with the utility model, they should all be included in the protection scope of the utility model.
