DETAILED DESCRIPTION

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, an embodiment of the utility model provides an auxiliary device for detecting bearing capacity of a bridge, comprising a guide rail 1, a slider 4 is movably provided on the guide rail 1, a first mounting mechanism 2 is fixedly installed on the slider 4, an ultrasonic detector body 5 is fixedly installed in the first mounting mechanism 2, the ultrasonic detector body 5 is connected to an ultrasonic detection probe 6 through a wire, a second mounting mechanism 3 is provided on one side of the slider 4, and the ultrasonic detection probe 6 is provided on the second mounting mechanism 3.

[0026] Furthermore, the guide rail 1 is composed of a plurality of splicing units 101 , both sides of the splicing units 101 are provided with limit grooves 102 , and both sides of the lower end of the slider 4 are rotatably mounted with rollers 401 , which are respectively rollingly connected in the limit grooves 102 on both sides.

[0027] In the present application, the guide rail 1 is installed on the surface of the bridge, and the slider 4 can be moved on the guide rail 1 through the roller 401, so that the ultrasonic detector body 5 can move along the track of the guide rail 1. The slider 4 drives the second mounting mechanism 3 to move synchronously, thereby driving the ultrasonic detection probe 6 to move. The ultrasonic detection probe 6 is in contact with the surface of the bridge under the action of the second mounting mechanism 3, and can detect the inside of the bridge during the movement.

[0028] Furthermore, the first mounting mechanism 2 includes a mounting frame 201 and a pressure block 202. The mounting frame 201 is fixedly mounted on the upper surface of the slider 4. The ultrasonic detector body 5 is mounted in the mounting frame 201, and one side is against the side wall of the mounting frame 201. The pressure block 202 is against the other side of the ultrasonic detector body 5. The two ends of the pressure block 202 away from the side of the ultrasonic detector body 5 are respectively provided with a guide rod 205 and a threaded rod 203. The guide rod 205 is fixedly connected to the pressure block 202 and slides through one side of the mounting frame 201. The threaded rod 203 is rotatably connected to the pressure block 202, and a threaded sleeve 204 is threadedly sleeved on the rod body, and the threaded sleeve 204 is fixedly mounted inside one side of the mounting frame 201.

[0029] In the present application, the first mounting mechanism 2 is used to mount the ultrasonic detector body 5 on the slider 4. During installation, the ultrasonic detector body 5 is placed inside the mounting frame 201 so that one side of the ultrasonic detector body 5 is in contact with the side wall of the mounting frame 201 away from the pressure block 202. Then, the threaded rod 203 is rotated. Through the threaded cooperation between the threaded rod 203 and the screw sleeve 204, the threaded rod 203 drives the pressure block 202 to move in the direction close to the ultrasonic detector body 5 until the ultrasonic detector body 5 is pressed tightly between the pressure block 202 and the side wall of the mounting frame 201, thereby completing the fixation of the ultrasonic detector body 5. Otherwise, the ultrasonic detector body 5 can be removed. Through this setting, ultrasonic detector bodies 5 of different specifications can also be installed and fixed, and the application range is wide. By setting the guide rod 205, it can guide and limit the pressure block 202 during its movement, thereby ensuring that the pressure block 202 moves smoothly and improving the tightness of the pressure block 202 and the side of the ultrasonic detector body 5.

[0030] Furthermore, a fixing frame 7 is fixedly mounted on the upper surface of the mounting frame 201 , and a handle 8 is fixedly mounted on the upper end of the fixing frame 7 .

[0031] In the specific setting, the fixing frame 7 is in an inverted U-shape and spans the outside of the ultrasonic detector body 5 , which can facilitate the staff to push the equipment to move on the one hand, and can also play a certain anti-collision role on the ultrasonic detector body 5 on the other hand.

[0032] Furthermore, the second mounting mechanism 3 includes a connecting plate 301 and a movable plate 302. The connecting plate 301 is fixedly connected to one side of the slider 4. The four corners of the upper surface of the movable plate 302 are fixedly connected to limiting rods 303. The upper end of the limiting rod 303 slides through the connecting plate 301. A spring 304 is sleeved on the body of the limiting rod 303. The two ends of the spring 304 are respectively fixedly connected to the connecting plate 301 and the movable plate 302. The ultrasonic detection probe 6 is fixedly installed in the middle of the movable plate 302. The upper end of the ultrasonic detection probe 6 slides through the connecting plate 301.

[0033] In the present application, the second mounting mechanism 3 is used to fix the ultrasonic detection probe 6, reducing the burden of manual detection. The ultrasonic detection probe 6 is installed on the movable plate 302, and the bottom of the ultrasonic detection probe 6 is placed against the bridge surface through the limiting rod 303, which can ensure the contact between the ultrasonic detection probe 6 and the bridge surface, thereby realizing automatic fitting detection during the movement of the ultrasonic detector body 5.

[0034] The working principle of this utility model:

[0035] The present application uses an ultrasonic detector body 5 and an ultrasonic detection probe 6 to assist in detecting whether there are cracks, fatigue damage and other problems in the bridge structure, so as to determine the bearing capacity of the bridge. During the detection, the handle 8 is held to push the ultrasonic detector body 5 and the ultrasonic detection probe 6 to move. The detection end of the ultrasonic detection probe 6 is pressed against the bridge surface through the limit rod 303, and the detection can be performed during the movement, thereby improving the detection efficiency and reducing the burden on the staff. After the detection is completed, the ultrasonic detector body 5 and the guide rail 1 can be disassembled for easy carrying and transportation. During disassembly, the threaded rod 203 is rotated to move the pressure block 202 outward to release the restriction on the ultrasonic detector body 5, and then the wire can be pulled out to disassemble the ultrasonic detector body 5.

[0036] To sum up: this kind of bearing capacity detection auxiliary device for bridges uses an ultrasonic detector body 5 and an ultrasonic detection probe 6 to assist in detecting whether there are cracks, fatigue damage and other problems in the bridge structure, thereby determining the bearing capacity of the bridge. By splicing a plurality of splicing units 101 into a guide rail 1, the volume of the device can be reduced for easy transportation. By setting a roller 401 to roll along the inner wall of the limiting groove 102, the ultrasonic detector body 5 and the ultrasonic detection probe 6 can be conveniently moved to achieve mobile detection. By setting a first mounting mechanism 2, ultrasonic detector bodies 5 of different specifications can be easily installed and fixed, thereby improving the convenience of operation. By setting a second mounting mechanism 3, it can be ensured that the detection end of the ultrasonic detection probe 6 is in contact with the bridge surface, thereby improving the reliability of detection.
