Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pile foundation bearing capacity detector. Background Art

[0002] The current pile bearing capacity detection device usually uses a reaction beam and a hydraulic cylinder. One method is the loading method, which is to load a counterweight on the reaction beam after the reaction beam is erected on the pile. The hydraulic cylinder is located between the reaction beam and the pile to apply pressure to the pile.

[0003] At present, the existing pile foundation detection (such as patent number: CN216586704U) discloses a pile foundation vertical bearing capacity detection device for construction engineering. The positioning rod and the positioning groove cooperate to keep the installed jack and the test pile coaxial, so that the test pile is evenly stressed, thereby improving the detection accuracy of the pile foundation vertical bearing capacity.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the pile foundation is positioned by assembling multiple pallets, but the pallets are arc-shaped in design, and the pile foundations have different shapes such as square and circular. The shape of the pallets cannot be adjusted. During use, the positioned pile foundation needs to be disassembled and replaced. Utility Model Content

DETAILED DESCRIPTION

[0021] The embodiment of the present application provides a pile foundation bearing capacity tester, which effectively solves the problem of positioning the pile foundation by assembling multiple clamping plates. However, the clamping plates are of arc-shaped design, and the pile foundations have different shapes such as square and round. The shape of the clamping plates cannot be adjusted. During use, the positioned pile foundation needs to be disassembled, assembled and replaced, and the limiting plate is pushed to slide downward at the bottom end of the second slide plate. The top end of the limiting plate applies a pulling force to the first return spring, allowing the first return spring to expand and contract to a certain extent. At the same time, one end of the limiting plate leaves the bottom ends of the multiple clamping plates, and the top end of the limiting plate leaves the clamping groove at the bottom end of the clamping plate, releasing the fixation of the clamping plate. At this time, under the reverse action force of the second return spring, the top end of the second return spring pushes the second connecting block, allowing the second connecting block to slide outward from one side of the second slide plate, pushing the clamping plates to move synchronously, and by pushing the top ends of the multiple clamping plates, the multiple clamping plates are adjusted to a stepped shape, or the clamping plates are adjusted to a horizontal shape, so as to squeeze and fix the circular or square pile foundation.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem of positioning the pile foundation by assembling multiple pallets, but the pallet is designed in an arc shape, and the pile foundation has different shapes such as square and round. The shape of the pallet cannot be adjusted. In use, the technical problem that the positioned pile foundation needs to be disassembled and replaced is solved. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a pile foundation bearing capacity tester, which includes a fixed plate 1, a first slide plate 11 is slidably installed on the top of the fixed plate 1, and second slide plates 12 are slidably installed on the two side ends of the first slide plate 11, and a placement groove is provided on the top of the fixed plate 1, which is located between the two first slide plates 11, and at least two clamping plates 22 are slidably installed on the side ends of each second slide plate 12, and two guide plates 17 are fixedly installed on the top of the fixed plate 1, and a driving rod 13 is fixedly installed on the inner side of each guide plate 17. By driving the driving rod 13, the driving rod 13 applies a thrust to the first slide plate 11, and the first slide plate 11 drives the bottom plate 16 to slide along the top of the guide plate 17, so that the two second slide plates 12 apply compression to the pile foundation to ensure the stability of the pile foundation sinking downward.

[0025] A hydraulic rod 14 is fixedly installed on the top of each second slide plate 12, and the same push plate 15 is fixedly installed on the top of the two hydraulic rods 14. The push plate 15 is of V-shaped design and is connected to the hydraulic rod 14 at both ends. A bottom plate 16 is fixedly installed on the bottom end of each first slide plate 11, and a rotating rod 18 is rotatably installed on the top of each first slide plate 11. Threaded rods 19 are rotatably installed on the two side ends of each first slide plate 11. The threaded rods 19 rotate on the side ends of the first slide plate 11, and the surface of the threaded rods 19 fits with the inner side of the first connecting block 21, applying a thrust to the first connecting block 21 to allow the second slide plate 12 to slide on the two side ends of the first slide plate 11, and adjust the spacing between the two second slide plates 12. The surface of each threaded rod 19 is slidably installed with the first connecting block 21.

[0026] A second connecting block 26 is fixedly installed on the side end of each splint 22, and a second return spring 27 is fixedly installed on the side end of each second connecting block 26. A mounting plate 23 is fixedly installed on the side end of each second slide plate 12, and a first return spring 24 is fixedly installed on the bottom end of each mounting plate 23. A limiting plate 25 is fixedly installed on the end of each first return spring 24. By pushing the limiting plate 25, the limiting plate 25 slides downward at the bottom end of the second slide plate 12, and the top end of the limiting plate 25 applies a pulling force to the first return spring 24, allowing the first return spring 24 to expand and contract to a certain extent. At the same time, one end of the limiting plate 25 leaves the bottom end of the multiple splints 22, and the top end of the limiting plate 25 leaves the slot at the bottom end of the splint 22, thereby releasing the fixation of the splint 22.

[0027] Working principle:

[0028] The first step is to push the limit plate 25 to allow the limit plate 25 to slide downward at the bottom end of the second slide plate 12. The top end of the limit plate 25 applies a pulling force to the first return spring 24, allowing the first return spring 24 to expand and contract to a certain extent. At the same time, one end of the limit plate 25 leaves the bottom ends of the plurality of clamping plates 22, and the top end of the limit plate 25 leaves the slot at the bottom end of the clamping plate 22, releasing the fixation of the clamping plate 22. At this time, under the reverse force of the second return spring 27, the top end of the second return spring 27 pushes the second connecting block 26, allowing the second connecting block 26 to slide outward from one side of the second slide plate 12, pushing the clamping plates 22 to move synchronously, and by pushing the top ends of the plurality of clamping plates 22 At the end, multiple clamps 22 are adjusted to a stepped shape, or the clamps 22 are adjusted to be horizontal, and the circular or square pile foundation is squeezed and fixed. Through the different sliding distances of multiple clamps 22, the top of the clamp 22 is close to the surface of the pile foundation. At the same time, under the pulling force of the first return spring 24, the limit plate 25 slides toward the second slide plate 12, and one end of the limit plate 25 is stuck into the bottom end of the clamp 22 to fix the clamp 22. Then, by driving the driving rod 13, the driving rod 13 applies a thrust to the first slide plate 11, and the first slide plate 11 drives the bottom plate 16 to slide along the top of the guide plate 17, so that the two second slide plates 12 squeeze the pile foundation to ensure the stability of the pile foundation sinking downward.

[0029] In the second step, the push plate 15 is driven by the hydraulic rod 14 to slide downward, and pressure is applied to the top of the pile foundation. The pile foundation slides downward inside the fixed plate 1. Due to the support of the two second slide plates 12, the pile foundation sinks vertically downward. At the same time, the rotating rod 18 is rotated to drive the bevel gear at the end to rotate, so that the two threaded rods 19 are rotated on the inner side of the first slide plate 11. At the same time, the threaded rod 19 rotates at the side end of the first slide plate 11, and the surface of the threaded rod 19 fits with the inner side of the first connecting block 21, applying a thrust to the first connecting block 21, so that the second slide plate 12 slides on the two side ends of the first slide plate 11. The spacing between the two second slide plates 12 can be adjusted to position pile foundations of different sizes, thereby increasing the versatility of use.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
