[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a bridge pile foundation displacement detection device, including a base plate 1, which can be fixed to the ground by bolts and other existing technologies, so as to support and fix a detection machine 5. A lifting mechanism 2 is provided on the top outer wall of the base plate 1, and the height of the detection machine 5 can be adjusted by the lifting mechanism 2 to adapt to bridge pile foundations of different heights.

[0032] Reference Figure 2 The lifting mechanism 2 includes a rotating block 201. The outer wall of the bottom end of the rotating block 201 is rotatably connected to the outer wall of the top end of the bottom plate 1. The inner wall of the bottom end of the rotating block 201 is rotatably connected to a threaded rod 202. When the height needs to be adjusted, the rotating block 201 can be rotated and the threaded rod 202 can be driven to rotate synchronously. The inner wall of the rotating block 201 is slidably connected to a moving rod 203. The moving rod 203 can move up and down in the inner wall of the rotating block 201 to adjust the height of the detection machine 5. The threaded rod 202 is threadedly connected to the inner wall of the bottom end of the moving rod 203. When the rotating block 201 drives the threaded rod 202 to rotate, the moving rod 203 can be driven to move. The outer wall of the moving rod 203 is provided with multiple groups of slots 207. The setting of multiple groups of slots 207 can adjust the detection machine 5 to multiple heights and fix it, which has higher adaptability.

[0033] Reference Figure 2 The inner wall of the moving rod 203 is slidably connected with an inner rod 206, and the inner wall of the inner rod 206 is provided with a limit assembly. The inner rod 206 is clamped with the moving rod 203 through the limit assembly, and the inner rod 206 can be moved up and down in the inner wall of the moving rod 203 through the limit assembly to roughly adjust the height of the detection machine 5. The outer wall of the moving rod 203 is fixedly connected with a slider 205, and the top outer wall of the bottom plate 1 is fixedly connected with a guide rod 204. The slider 205 is slidably connected to the outer wall of the guide rod 204. When the rotating block 201 rotates, the threaded rod 202 rotates and drives the moving rod 203 to move, and drives the slider 205 to move synchronously. Since the slider 205 is slidably connected to the guide rod 204, it can play a guiding role, so that the slider 205 and the moving rod 203 maintain a vertical moving state, so that the height of the inner rod 206 and the detection machine 5 can be accurately adjusted, so that the detection machine 5 contacts the top of the bridge pile foundation for detection.

[0034] Reference Figure 2 The top outer wall of the inner rod 206 is provided with an adjusting mechanism 3, through which the distance of the detection machine 5 in the horizontal position can be adjusted, and the operator does not need to hold the detection machine 5 for detection. The outer wall of the inner rod 206 is rotatably connected to the support rod 4, and the top of the support rod 4 can be clamped with the bottom outer wall of the rotating rod 301 to support the rotating rod 301. This is a prior art. The outer wall of the adjusting mechanism 3 is provided with a detection machine 5, which is the main body of the bridge pile foundation displacement detection equipment, and can be easily and quickly disassembled and installed on the adjusting rod 302. It is a prior art well known to professionals in this field and will not be repeated here.

[0035] Reference Figure 2 The limit assembly includes a wedge 602, which keeps the arc surface upward. When the inner rod 206 is pulled upward, it can be easily pulled. The outer wall of the wedge 602 is elastically connected to the inner wall of the inner rod 206 through a spring A601. When the inner rod 206 is pulled upward, the arc surface of the wedge 602 is squeezed by the inner wall of the slot 207 and moves inward along the inner wall of the inner rod 206, so that the inner rod 206 can be pulled upward. One end of the spring A601 is fixedly connected to the inner wall of the inner rod 206, and the other end of the spring A601 is fixedly connected to the outer wall of the wedge 602. When it is pulled to a suitable position When the inner rod 206 is moved downward, the wedge block 602 is pressed inward to disengage the wedge block 602 from the slot 207, and the inner rod 206 is moved downward to the position of the inner rod 206.

[0036] Reference Figure 3 The adjusting mechanism 3 includes a rotating rod 301, which is rotatably connected to the outer wall of the top end of the inner rod 206. The rotating rod 301 can be flipped downward and folded up to save space and is easy to carry. The inner wall of the rotating rod 301 is slidably connected with an adjusting rod 302. The detection machine 5 is fixedly connected to the outer wall of the adjusting rod 302. The adjusting rod 302 can move laterally in the inner wall of the rotating rod 301, so as to adjust the distance between the detection machine 5 and the base plate 1, so as to detect the bridge pile foundation, and there is no need to support the detection machine 5 by hand for detection. The inner wall of the adjusting rod 302 is elastically connected with a block 305 through a spring B304. The block 305 is square and can limit the adjusting rod 302. After the length of the adjusting rod 302 is adjusted, it is fixed.

[0037] Reference Figure 3One end of the spring B304 is fixedly connected to the outer wall of the block 305, and the other end of the spring B304 is fixedly connected to the inner wall of the adjusting rod 302. When not affected by external force, the spring B304 drives the block 305 to pop up due to its own elastic force and engages with the groove 303, so that the length between the adjusting rod 302 and the rotating rod 301 can be fixed. The outer wall of the block 305 is slidably connected to the inner wall of the adjusting rod 302, and the top outer wall of the rotating rod 301 is provided with multiple groups of grooves 303, and the block 305 is engaged with the groove 303. When the adjusting rod 302 needs to be pulled out or retracted into the rotating rod 301, the block 305 can be pressed downward to disengage from the groove 303, so that the adjusting rod 302 can be moved and fixed conveniently and quickly, and there is no need to fix it by turning the bolts multiple times, which is more time-saving and labor-saving.

[0038] Working principle: When in use, the operator can first pull the inner rod 206 upwards, so that the wedge block 602 is continuously squeezed by the inner wall of the slot 207 and moves inward toward the inner wall of the inner rod 206, and the inner rod 206 can be pulled upwards. When the inner rod 206 moves upwards to a rough height, the wedge block 602 pops outwards due to the elastic force of the spring A601 itself and engages with the slot 207, thereby fixing the height of the inner rod 206. Then, the rotating rod 301 is flipped upwards, and the support rod 4 is connected to the bottom end of the rotating rod 301 to support the rotating rod 301 and keep the rotating rod 301 in a horizontal state. Then, the detection machine 5 is installed on the adjusting rod 302. Then, according to the height of the bridge pile foundation, the height of the detection machine 5 can be accurately adjusted so that the detection machine 5 contacts the top of the bridge pile foundation.

[0039] At this time, the operator can rotate the rotating block 201 to drive the threaded rod 202 to rotate, so that the moving rod 203 moves. The moving rod 203 and the slider 205 are guided by the guide rod 204 to maintain a vertical moving state. Therefore, after roughly adjusting the height of the inner rod 206 through the wedge block 602, the height of the detection machine 5 can be adjusted more accurately to adapt to bridge pile foundations of different heights. The operation is simpler and the adaptability is higher.

[0040] The operator can then press the block 305 downward to disengage the block 305 from the groove 303, and then pull the adjusting rod 302 outward. When the adjusting rod 302 moves to the point where the detection machine 5 is completely placed on the bridge pile foundation, the operator can stop pulling the adjusting rod 302, so that the block 305 pops up due to the elastic force of the spring B304 itself and engages with the groove 303. This allows the operator to quickly and conveniently fix the length between the adjusting rod 302 and the rotating rod 301. The lateral distance of the detection machine 5 can be adjusted and fixed without having to turn the bolts multiple times. The bridge pile foundation can also be inspected for displacement without the operator having to hold the detection machine 5. Furthermore, by setting multiple sets of grooves 303, the distance between the base plate 1 and the detection machine 5 can be moved to adapt to different detection scenarios.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
