Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0022] In one embodiment, as Figures 1-5As shown in the figure, a building pile foundation detection device includes a fixed ring 1. A sleeve hole 2 is provided in the middle of the upper end face of the fixed ring 1. A toothed ring 3 is provided in the middle of the upper end face of the fixed ring 1. The teeth on the toothed ring 3 are arranged on the outside. A plurality of connecting shafts 4 are connected to the upper end face of the fixed ring 1 and away from the sleeve hole 2 by bearings. The plurality of connecting shafts 4 are arranged in a circular array with respect to the toothed ring 3. The upper end face of each connecting shaft 4 is fixedly connected with a connecting column 5. A gear 6 is fixedly sleeved in the middle of the surface of the connecting column 5. The gear 6 meshes with the toothed ring 3. The upper end face of each connecting column 5 and near the edge is fixedly connected with a traction rod 7. A connecting block 8 is provided on the upper end face of the connecting column 5. An activity groove 9 is opened inside the connecting block 8. The traction rod 7 is movably sleeved in the activity groove 9. The middle of the side of the connecting block 8 close to the sleeve hole 2 is fixedly connected with a connecting rod 10. The middle of the side of the connecting rod 10 close to the sleeve hole 2 is fixedly connected with a limiting clamping block 11. A plurality of first support rods 12 are fixedly connected to the edge of the upper end face of the fixed ring 1. The upper end faces of the plurality of first support rods 12 are jointly fixedly connected with a bearing plate 13.

[0023] In order to prevent the connecting block 8 from rotating and enable the connecting block 8 to only move linearly, a plurality of support blocks 14 are fixedly connected to the top surface of the fixed ring 1 and near the edge. Activity holes are opened at the tops of the plurality of support blocks 14. Guide rods 15 are fixedly connected to the middle of the sides of the plurality of connecting blocks 8 away from the sleeve hole 2. One end of the guide rod 15 away from the connecting block 8 is movably sleeved in the activity hole.

[0024] In order to facilitate driving the connecting column 5 to rotate, a first support plate 16 is fixedly connected to the rear side of the edge of the fixed ring 1. A support frame 17 is fixedly connected to the top surface of the first support plate 16. An electric push rod 18 is fixedly connected to the top surface of the support frame 17. The telescopic end of the electric push rod 18 is fixedly connected to the rear end face of the rear guide rod 15.

[0025] In order to support the toothed ring 3 and at the same time not affect the rotation of the toothed ring 3, a connecting sleeve 19 is fixedly sleeved inside the fixed ring 1. A connecting disk 20 is fixedly sleeved at the lower end of the surface of the connecting sleeve 19. A plurality of second support rods 21 are fixedly connected to the upper end face of the fixed ring 1 and near the sleeve hole 2. The upper end faces of the plurality of second support rods 21 are jointly fixedly connected with a support ring 22. A plug-in slot 23 is opened inside the support ring 22. The edge of the connecting disk 20 is movably sleeved in the plug-in slot 23. A plurality of installation holes are opened at the top and bottom of the plug-in slot 23. The plurality of installation holes are arranged in a circular array with respect to the axis. A ball 24 is movably sleeved in each installation hole. The surfaces of the upper and lower balls 24 are respectively in contact with the end faces of the upper and lower sides of the connecting disk 20 and near the edge. The ball 24 reduces the frictional resistance between the connecting disk 20 and the support ring 22, making the rotation of the connecting disk 20 smoother.

[0026] In order to balance the weights of the first support plate 16, the support frame 17, and the electric push rod 18 and prevent the device from tilting backward, second support plates 25 are fixedly connected to the front sides of the edges of the fixing ring 1. A balance weight 26 is fixedly connected to the top surface of each second support plate 25, and a spirit level 27 is fixedly connected to the front side of the top surface of the second support plate 25, which facilitates checking whether the device is tilted through the spirit level 27.

[0027] In order to increase the frictional resistance between the limit clamping block 11 and the pile foundation and make the clamping more stable, the inner side of the limit clamping block 11 is arc-shaped, and an anti-slip pad is fixedly connected to the inner side of the limit clamping block 11. The arc-shaped setting makes the inner side of the limit clamping block 11 more conform to the surface of the pile foundation.

[0028] Working principle: When the present utility model is in use, the top end of the pile foundation is sleeved into the sleeve hole 2, and the upper end of the pile foundation sequentially passes through the connecting sleeve 19 and the gear ring 3, so that the top of the pile foundation fits against the bottom surface of the bearing plate 13. Then, the electric push rod 18 is started, and the electric push rod 18 pushes the rear guide rod 15 forward. The rear guide rod 15 pushes the rear connecting block 8 forward. When the rear connecting block 8 moves forward, the rear traction rod 7 will rotate. The rear traction rod 7 drives the rear limit clamping block 11 to move towards the pile foundation. The rear traction rod 7 drives the rear connecting column 5 to rotate. The rear connecting column 5 drives the rear gear 6 to rotate. The rear gear 6 drives the gear ring 3 to rotate. The gear ring 3 drives the remaining gears 6 to rotate, so that the remaining limit clamping blocks 11 also move towards the pile foundation to clamp and fix the pile foundation and keep it stable on the pile foundation. In this way, all the limit clamping blocks 11 can move synchronously to clamp and fix the pile foundation, thus saving a large amount of operation time, making it relatively simple to clamp and fix the device on the pile foundation, improving the practicability of the device, and eliminating the need for manual operation to move the limit clamping block 11, making the operation easier and more labor-saving.

For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0030] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
