Description

Technical Field

[0001] This utility model relates to the field of testing equipment support technology, and in particular to a pile foundation testing equipment support that is easy to disassemble and assemble. Background Technology

[0002] The core function of pile foundations is to effectively transfer the load of a building to the more stable strata below, thereby providing solid support for the building and ensuring its overall stability. During pile driving, controlling the verticality of the pile foundation is crucial: if the pile foundation deviates from its vertical position, the pile body is prone to bending deformation, which directly weakens the bearing capacity of the pile foundation and thus threatens the stability and safety of the building.

[0003] A search revealed a Chinese utility model patent with patent number CN223469990U, which discloses a support for a pile foundation testing equipment that is easy to disassemble and assemble. Compared with the prior art, this utility model patent with Chinese patent number CN223469990U uses a telescopic rod that is slidably locked in a device groove inside a rocker arm. This allows workers to adjust the position of the telescopic rod in the device groove inside the rocker arm according to the unevenness of the ground, ensuring that the placement plate is in a horizontal state.

[0004] However, in actual use, the above-mentioned device only achieves horizontal adjustment of the placement plate through the cooperation of the telescopic rod and the rocker device groove. But when actually testing pile foundations of different diameters or different points of the pile foundation, it is necessary to disassemble the support fixing structure and reposition it. This is not only cumbersome to operate, but also difficult to guarantee the accuracy of the alignment of the test points on the same plane. Therefore, it is necessary to propose a pile foundation testing equipment support that is easy to disassemble and assemble. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which requires disassembling the support structure for repositioning when actually testing pile foundations of different diameters or different points of the pile foundation. This is not only cumbersome to operate, but also makes it difficult to ensure the accuracy of the test point alignment. Therefore, this utility model proposes a pile foundation testing equipment support that is easy to disassemble and assemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support frame for a pile foundation testing device that is easy to disassemble and assemble includes a placement plate, a T-shaped sliding block, and an arc-shaped worm gear, wherein the placement plate and the T-shaped sliding block are slidably connected.

[0008] A servo motor is fixedly installed on the upper part of the T-shaped sliding block, and a worm gear is fixedly connected to the output shaft of the servo motor.

[0009] The worm meshes with the bow-shaped worm wheel, and a limit rod is slidably connected to the inner side of the bow-shaped worm wheel;

[0010] An inverted plate is fixedly connected to the inner side of the bow-shaped worm gear. The inverted plate is rotatably connected to a rotating shaft. A scale is fixedly connected to the rotating shaft coaxially. A T-shaped abutment is fixedly connected to the outer side of the rotating shaft. The rotation of the worm gear drives the bow-shaped worm gear and the T-shaped abutment to rotate synchronously. The T-shaped abutment abuts against the pile foundation and drives the scale to rotate synchronously.

[0011] The above technical solution further includes:

[0012] Specifically, the bottom of the placement plate is fixedly connected to multiple sets of rotating rods, and the outside of each rotating rod is hinged with a telescopic rod, which is an adjustable telescopic rod.

[0013] Specifically, a sliding groove is provided on the upper part of the placement plate, and a lead screw is rotatably connected to the sliding groove. The lead screw is threadedly engaged with the T-shaped sliding block.

[0014] Specifically, the dial surface is provided with evenly distributed angle scale markings.

[0015] Specifically, a connecting pipe is fixedly connected to the side of the bow-shaped worm gear away from the servo motor, and the side of the connecting pipe away from the bow-shaped worm gear is fixedly connected to the C-shaped plate. A bow-shaped sliding groove is provided on the inner side of the bow-shaped worm gear, and the bow-shaped sliding groove is slidably connected to the limiting rod.

[0016] Specifically, there are two sets of limiting rods, and the lower part of the limiting rods is detachably connected to the placement plate.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, after the limiting rod is disassembled, the lead screw can drive the T-shaped sliding block to adjust the horizontal position of the detection component, adapting to the detection point requirements of different pile foundations. After the limiting rod is installed, it cooperates with the bow-shaped sliding groove to stably constrain the rotation trajectory of the bow-shaped worm gear. With the worm gear transmission driven by the servo motor, it can drive the T-shaped stop block to rotate at multiple angles. At the same time, the scale provides real-time feedback of angle data, which not only ensures the detection accuracy but also simplifies the disassembly and assembly process. It can ensure the accuracy of the alignment of detection points on the same plane and greatly improve the adaptability to pile foundations of different sizes and with different detection requirements.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-4 As shown, the present invention proposes a pile foundation testing equipment support that is easy to disassemble and assemble, including a placement plate 1, a T-shaped sliding block 4 and an arc-shaped worm gear 6, wherein the placement plate 1 and the T-shaped sliding block 4 are slidably connected.

[0027] A servo motor 5 is fixedly installed on the upper part of the T-shaped sliding block 4, and a worm gear 501 is fixedly connected to the output shaft of the servo motor 5.

[0028] The worm 501 meshes with the bow-shaped worm wheel 6, and the inner side of the bow-shaped worm wheel 6 is slidably connected to the limit rod 7;

[0029] An incline plate 9 is fixedly connected to the inner side of the bow-shaped worm gear 6. An incline plate 9 is rotatably connected to a rotating shaft 901. A dial 902 is fixedly connected to the rotating shaft 901 on the same axis. A T-shaped abutment 10 is fixedly connected to the outer side of the rotating shaft 901. The rotation of the worm 501 drives the bow-shaped worm gear 6 and the T-shaped abutment 10 to rotate synchronously. The T-shaped abutment 10 abuts against the pile foundation and drives the dial 902 to rotate synchronously.

[0030] Furthermore, the placement plate 1 provides the overall installation base. After the T-shaped sliding block 4, with the servo motor 5 fixed on it, slides to the target position, the servo motor 5 starts to drive the worm gear 501 connected to the output shaft to rotate. The worm gear 501 drives the meshing bow-shaped worm wheel 6 to rotate. The limiting rod 7 slidably connected to the inner side of the bow-shaped worm wheel 6 guides and limits its rotation trajectory. It is worth noting that the limiting rod 7 is detachably connected to the placement plate 1. The bow-shaped worm wheel 6 drives the inner fixed C-shaped plate 9 to rotate synchronously, causing the rotating shaft 901 rotatably connected to the C-shaped plate 9 to rotate accordingly. The T-shaped abutment 10 fixed to the outer side of the rotating shaft 901 rotates synchronously. When the T-shaped abutment 10 abuts against the pile foundation, the reaction force of the pile foundation on the T-shaped abutment 10 causes the rotating shaft 901 to drive the coaxial fixed dial 902 to rotate synchronously, thereby providing feedback on the detection angle.

[0031] The bottom of the placement plate 1 is fixedly connected to multiple sets of rotating rods 101. The outer side of the rotating rods 101 is hinged to a telescopic rod 2, which is a telescopic rod with adjustable length.

[0032] Furthermore, the placement plate 1 serves as the load-bearing foundation of the entire support. Multiple sets of rotating rods 101 fixed at its bottom can rotate around themselves, driving the telescopic rods 2 hinged on the outside to adjust their opening angle to adapt to the support range requirements of different pile foundation testing scenarios. Then, by adjusting the telescopic rods 2, which are adjustable in length, the placement plate 1 is adjusted to a horizontal height that meets the testing requirements, ultimately providing support for the entire support system.

[0033] The upper part of the placement plate 1 is provided with a sliding groove 3, and the sliding groove 3 is rotatably connected to a lead screw 301, which is threadedly engaged with the T-shaped sliding block 4.

[0034] Furthermore, the sliding groove 3 on the upper part of the placement plate 1 provides a guide trajectory for the movement of the T-shaped sliding block 4. When the lead screw 301, which is rotatably connected to the sliding groove 3, is rotated, the rotational motion of the lead screw 301 is converted into the linear movement of the T-shaped sliding block 4 along the sliding groove 3 due to the threaded engagement between the lead screw 301 and the T-shaped sliding block 4. This, in turn, drives the components on the T-shaped sliding block 4 to adjust to the horizontal position required for pile foundation testing.

[0035] The dial 902 has evenly distributed angle scale markings on its surface.

[0036] Furthermore, when the T-shaped abutment block 10 abuts against the pile foundation and drives the rotating shaft 901 to rotate synchronously, the scale 902 rotates together with the rotating shaft 901. The evenly distributed angle scale markings on its surface can clearly and intuitively present the real-time rotation angle, making it convenient for operators to quickly read the angle data corresponding to the pile foundation detection, and providing an intuitive reference for the accuracy of the detection results.

[0037] A connecting pipe 8 is fixedly connected to the side of the bow-shaped worm gear 6 away from the servo motor 5. The side of the connecting pipe 8 away from the bow-shaped worm gear 6 is fixedly connected to the inverted plate 9. A bow-shaped sliding groove 601 is opened on the inner side of the bow-shaped worm gear 6. The bow-shaped sliding groove 601 is slidably connected to the limiting rod 7.

[0038] Furthermore, when the servo motor 5 drives the worm gear 501 to rotate, the worm gear 501 drives the bow-shaped worm wheel 6 to rotate. The bow-shaped sliding groove 601 on the inner side of the bow-shaped worm wheel 6 slides along the limit rod 7, providing guidance and trajectory constraint for the rotation of the bow-shaped worm wheel 6. At the same time, the bow-shaped worm wheel 6 transmits the rotation to the connected convex plate 9 through the connecting pipe 8 on the side away from the servo motor 5, so that the convex plate 9 moves synchronously with the bow-shaped worm wheel 6, providing power transmission and installation support for the angle adjustment of subsequent components such as the rotating shaft 901 and the T-shaped abutment 10.

[0039] There are two sets of limit rods 7, and the lower part of the limit rod 7 is detachably connected to the placement plate 1.

[0040] Furthermore, after disassembling the two sets of limiting rods 7, their connection with the placement plate 1 is released, and the bow-shaped worm gear 6 is no longer constrained. At this time, rotate the lead screw 301 in the sliding groove 3. The lead screw 301 drives the T-shaped sliding block 4 to move along the sliding groove 3 through threaded engagement. The T-shaped sliding block 4 synchronously drives the servo motor 5 and the worm gear 501 connected to the output shaft on it to move. After moving to the position suitable for pile foundation testing, thread the lower part of the two sets of limiting rods 7 to the placement plate 1. The limiting rods 7 pass through the bow-shaped sliding groove 601 of the bow-shaped worm gear 6 to limit the position of the bow-shaped worm gear 6. Start the servo motor 5 to drive the worm gear 501 to rotate. The worm gear 501 drives the bow-shaped worm gear 6 to rotate stably and synchronously along the limiting rods 7 through meshing.

[0041] In this embodiment, the specific implementation is as follows: First, the opening angle of the outer hinged telescopic rod 2 is adjusted by multiple sets of rotating rods 101 fixed at the bottom of the placement plate 1. Then, the telescopic rod 2 is adjusted to adjust the placement plate 1 to a horizontal detection height to provide stable support. Subsequently, the two sets of limiting rods 7 are removed to release the constraint on the bow-shaped worm gear 6. The lead screw 301 in the sliding groove 3 is rotated, and its thread engagement with the T-shaped sliding block 4 drives the T-shaped sliding block 4 and the servo motor 5 fixed at the top, and the worm gear 501 connected to the output shaft of the servo motor 5 to move along the sliding groove 3 to the appropriate position. Then, the lower part of the two sets of limiting rods 7 is threadedly connected to the placement plate 1, so that the limiting rods 7 pass through... The bow-shaped sliding groove 601 inside the bow-shaped worm gear 6 defines its position. The servo motor 5 is started to drive the worm 501 to rotate. The worm 501 drives the meshing bow-shaped worm gear 6 to rotate stably along the limit rod 7. The bow-shaped worm gear 6 transmits the rotation to the C-shaped plate 9 through the connecting pipe 8 on the side away from the servo motor 5, so that the rotating shaft 901 connected to the C-shaped plate 9 and the T-shaped abutment 10 fixed on the outside rotate synchronously. When the T-shaped abutment 10 abuts against the pile foundation, the reaction force of the pile foundation causes the rotating shaft 901 to drive the coaxially fixed dial 902 to rotate synchronously. The operator reads the detection angle data through the angle scale markings evenly distributed on the surface of the dial 902.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
