DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] As attached Figure 1-6A highway bridge steel structure detection device is shown, and a switching mechanism is provided on the highway bridge steel structure detection device. The setting of the switching mechanism can quickly switch different gap detection rulers 3 for rapid gap detection, greatly improving the detection efficiency. The specific structural setting of the switching mechanism is as follows.

[0025] In this technical solution, as shown in the attached Figure 1-3 As shown, the switching mechanism includes a rotating rod 4 fixedly mounted on the inner wall of the sleeve shaft 2, and a rotating cap 5 is fixedly connected to the top of the rotating rod 4, a rotating ring 6 is fixedly mounted on the outer wall of the rotating cap 5, and an extrusion screw 7 is threadedly connected to the inner wall of the rotating ring 6 and at a position on one side of the rotating cap 5; a connecting column 8 is fixedly connected to the upper surface of the sleeve strip 1, and a supporting ring 9 is fixedly mounted on the top of the connecting column 8, and a reinforcement ring 10 is fixedly connected to the top of the supporting ring 9, the extrusion screw 7 and the reinforcement ring 10 are squeezed between them, and the outer wall of the rotating ring 6 is rotatably connected to the sleeve strip 1, and the cross-sectional shape of the rotating cap 5 is polygonal.

[0026] In this technical solution, as shown in the attached Figure 2-3 As shown, a rotating cap 11 is fixedly installed on the top of the extrusion screw 7. The rotating cap 11 and the extrusion screw 7 are both made of stainless steel. By rotating the rotating cap 11 forward, the rotating cap 11 drives the extrusion screw 7 to rotate, thereby achieving stable rotation of the extrusion screw 7. The upper surface of the gap detection ruler 3 is engraved with a scale mark 12. Multiple gap detection rulers 3 are arranged from top to bottom so that the scale mark 12 can display the thickness of the gap detection ruler 3. Gap detection rulers 3 of different thicknesses can be selected according to actual detection needs to achieve different thickness gap detection of highway bridge steel structures. The outer wall of the rotating rod 4 is fixedly connected to the lower surface of the sleeve strip 1 with a limit collar 13. The limit collar 13 is rotatably connected to the sleeve strip 1 so that the rotation of the gap detection ruler 3 will drive the limit collar 13 to rotate synchronously, thereby stably achieving the rotation operation of the limit collar 13 on the sleeve strip 1.

[0027] When the highway bridge steel structure detection device of this technical solution is in use, the rotating cap 11 is rotated forward, and the rotating cap 11 drives the extrusion screw 7 to rotate. The extrusion screw 7 rotates on the internal thread of the rotating ring 6, and the extrusion screw 7 moves upward from the reinforcement ring 10, so that the extrusion screw 7 is separated from the reinforcement ring 10, and the connecting column 8 is supported by the sleeve strip 1. The connecting column 8 provides support force for the support ring 9, and the support ring 9 provides support force for the reinforcement ring 10. In this way, the rotating cap 5 is rotated, and the rotating cap 5 drives the rotating ring 6 to rotate. At the same time, the rotating cap 5 drives the rotating rod 4 to rotate, and the rotating rod 4 rotates inside the sleeve strip 1, and the rotating rod 4 drives the sleeve shaft 2 to rotate.

[0028] At the same time, the sleeve shaft 2 drives multiple gap detection rulers 3 to rotate, so that the scale marks 12 on the multiple gap detection rulers 3 rotate the gap thickness, causing the multiple gap detection rulers 3 to rotate. After selecting the corresponding gap detection ruler 3, the rotating cap 11 is reversed, and the rotating cap 11 drives the extrusion screw 7 to rotate. The extrusion screw 7 and the swivel 6 are squeezed on the reinforcement ring 10 under the action of the thread, so that the swivel 6 can be fixed. In this way, the gap detection ruler 3 of corresponding thickness is selected, and the sleeve strip 1 is moved. The sleeve strip 1 drives the sleeve shaft 2 to move the gap detection ruler 3. The gap detection ruler 3 is inserted into the detection gap of the steel structure of the highway bridge to realize the detection operation to check whether it meets the specified gap.

[0029] Example 2:

[0030] In this technical solution, as shown in the attached Figure 4-6 As shown, an adjustment assembly is provided on one side of the sleeve strip 1; the adjustment assembly includes a slide frame 14 arranged on one side of the sleeve strip 1, and the inner wall of the slide frame 14 is rotatably connected to an adjusting screw 15; the outer wall of the adjusting screw 15 is threadedly connected to a sleeve block 16, one side of the sleeve block 16 is fixedly connected to a linkage strip 17, and one side of the linkage strip 17 is welded with a connecting block 18, the connecting block 18 is fixedly connected to the sleeve strip 1, one end of the adjusting screw 15 is fixedly connected to a linkage cap 19, and a handle 20 is welded to one side of the outer wall of the slide frame 14; the cross-sectional shape of the handle 20 is concave.

[0031] When the present technical solution is in use, the extended use can be achieved by rotating the linkage cap 19, which drives the adjusting screw 15 to rotate, while the other hand is held on the handle 20, and the handle 20 supports the slide frame 14. The adjusting screw 15 drives the sleeve block 16 to move left under the action of the thread transmission force, and the sleeve block 16 drives the linkage bar 17 to move left, and the linkage bar 17 drives the connecting block 18 to move left. The connecting block 18 causes the sleeve strip 1 to move left, and the sleeve strip 1 drives the sleeve shaft 2 to move multiple gap detection rulers 3 to the left. The gap detection ruler 3 can be adjusted to extend the distance.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
