Description

Technical Field

[0001] This utility model relates to the field of static load testing technology, specifically to a large-tonnage horizontal thrust testing device. Background Technology

[0002] Static load test refers to the test method of applying vertical pressure, vertical uplift force or horizontal thrust to the top of the pile in stages, and observing the settlement, uplift displacement or horizontal displacement of the top of the pile over time, in order to determine the corresponding vertical compressive bearing capacity, vertical uplift bearing capacity or horizontal bearing capacity of a single pile.

[0003] Static load tests are generally conducted using jacks. During the test, the jacks are suspended in the air, which makes them prone to tilting or even falling off, affecting the efficiency of the horizontal thrust test and reducing the effectiveness of the device.

[0004] Therefore, we proposed a large-tonnage horizontal thrust test device to solve the problems mentioned above. Utility Model Content

A column is fixedly installed on one side of the top of the test platform, and a support block is provided on the other side of the top of the test platform. The jack body is located on top of the support block. A connecting block is fixedly installed at one end of the jack body. A groove is provided on the top of the connecting block, and a disassembly component is provided in the inner cavity of the groove. A slot is provided on one side of the connecting block, and a plug is movably inserted into the inner cavity of the slot. Slots are provided on both the front and rear sides of the plug. An arc-shaped block is fixedly installed on one side of the plug. A rectangular plate is fixedly installed on the top of the test platform near the other side, and a limit component is provided on one side of the rectangular plate.

[0007] The limiting component includes a rectangular block fixedly installed on one side of the rectangular plate near the front and rear sides, and a threaded rod rotatably connected to the rectangular block located on the rear side. The front end of the threaded rod moves through the adjacent rectangular block and is fixedly installed with a knob. Threaded sleeves are threadedly connected to the outer periphery of the threaded rod near the front and rear ends. Connecting rods are fixedly installed on the top of the threaded sleeves near the two sides. Clamping plates are fixedly installed at the ends of two adjacent connecting rods.

[0008] Preferably, a limiting block is fixedly installed on the other side of the threaded sleeve, and a limiting rod is provided through the limiting blocks. The front and rear ends of the limiting rod are fixedly connected to the adjacent rectangular blocks respectively.

[0009] Preferably, a pull rod is movably inserted through the front side of the knob near the top, and several limiting holes are provided on the rectangular block on the front side. The rear end of the pull rod is movably inserted into the inner cavity of the limiting hole. A return spring is movably sleeved on the outer periphery of the pull rod near the front end, and the front and rear ends of the return spring are respectively fixedly connected to the pull rod and the knob.

[0010] Preferably, the plurality of the limiting holes are arranged in a circular array with the center of the rear side of the knob as the center.

[0011] Preferably, the disassembly assembly includes a support rod rotatably connected to the middle position of the bottom of the groove cavity and a rotating gear fixedly installed on the top of the support rod. Both sides of the rotating gear are meshed with rack plates, and a toggle plate is fixedly installed on the top of the rack plate on the other side. Bent rod A and bent rod B are fixedly installed on the bottom of the rack plate respectively.

[0013] Preferably, each of the rack plates has a compression telescopic rod fixedly installed on its opposite end, and the opposite end of the compression telescopic rod is fixedly connected to the inner wall of the adjacent groove cavity, and a compression spring is movably sleeved on the outer periphery of each compression telescopic rod, and the two ends of the compression spring are fixedly connected to the adjacent rack plate and the inner wall of the groove cavity, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When using the jack body for horizontal thrust testing, with the cooperation of the limiting component, the threaded connection between the threaded sleeve and the connecting rod on the outer circumference of the threaded rod can cause the two clamping plates to move to opposite sides under the rotation of the threaded rod. This can limit the jack body and prevent it from tilting or even falling off during the test, thereby improving the efficiency of subsequent horizontal thrust testing of the jack body.

[0016] 2. When the arc block needs to be replaced, with the cooperation of the disassembly components, when the adjacent rack plate moves backward, the other rack plate can be moved forward under the transmission of the rotating gear. With the connection of the adjacent bent rods A and B, the two locking blocks can be moved to the side away from each other, thereby moving away from the inner cavity of the adjacent locking slot, which facilitates the replacement of the arc block. This makes the jack body suitable for testing cylindrical objects of different sizes, thus improving the range of applications of the device. Attached Figure Description

[0024] Example 1

[0025] Please see Figure 1-5A large-tonnage horizontal thrust testing device includes a test platform 1 and a jack body 5 located near the middle of the top of the test platform 1. A column 2 is fixedly installed on one side of the top of the test platform 1, and a support block 4 is set on the other side of the top of the test platform 1. The jack body 5 is located on top of the support block 4. A connecting block 6 is fixedly installed on one end of the jack body 5. A groove is formed on the top of the connecting block 6, and a disassembly component 8 is set in the inner cavity of the groove. A slot is formed on one side of the connecting block 6, and an insert block 10 is movably inserted into the inner cavity of the slot. Slots are formed on both the front and rear sides of the insert block 10. An arc-shaped block 7 is fixedly installed on one side of the insert block 10. The top of the test platform 1 near the other side... A rectangular plate 3 is fixedly installed on the side, and a limit component 9 is provided on one side of the rectangular plate 3. The limit component 9 includes a rectangular block 91 fixedly installed on one side of the rectangular plate 3 near the front and rear sides, and a threaded rod 92 rotatably connected to the rectangular block 91 located on the rear side. (The outer periphery of the threaded rod 92 has opposite external threads near the front and rear ends, and the thread precision is the same.) The front end of the threaded rod 92 moves through the adjacent rectangular block 91 and is fixedly installed with a knob 93. The outer periphery of the threaded rod 92 is threadedly connected to the front and rear ends with threaded sleeves 94. The top of the threaded sleeves 94 is fixedly installed with connecting rods 95 near both sides. The ends of two adjacent connecting rods 95 are fixedly installed with clamping plates 96.

[0026] Specifically, during the horizontal thrust test using the jack body 5, with the cooperation of the limiting component 9, the threaded sleeve 94 and the connecting rod 95 connected to the threaded rod 92 can move the two clamping plates 96 to the opposite side under the rotation of the threaded rod 92, thereby limiting the jack body 5 and preventing the jack body 5 from tilting or even falling off during the test, thus improving the efficiency of the subsequent horizontal thrust test of the jack body 5.

[0027] Limiting blocks 941 are fixedly installed on the other side of the threaded sleeve 94, and limiting rods 942 are provided through the limiting blocks 941. The front and rear ends of the limiting rods 942 are fixedly connected to the adjacent rectangular blocks 91 respectively.

[0028] Specifically, by setting the limit block 941 and the limit rod 942, the movement of the threaded sleeve 94 can be limited, thereby improving the stability of the threaded sleeve 94 during movement.

[0029] A pull rod 931 is movably inserted through the front side of the knob 93 near the top. Several limiting holes 932 are provided on the rectangular block 91 on the front side. The limiting holes 932 are arranged in a circular array with the rear center of the knob 93 as the center. The rear end of the pull rod 931 is movably inserted into the inner cavity of the limiting hole 932. A return spring 933 is movably sleeved on the outer periphery of the pull rod 931 near the front end. The front and rear ends of the return spring 933 are fixedly connected to the pull rod 931 and the knob 93, respectively.

[0030] Specifically, by setting the pull rod 931 to be inserted into the inner cavity of the adjacent limiting hole 932, the rotation position of the knob 93 can be limited to prevent it from rotating accidentally. Furthermore, by setting the return spring 933, the end of the pull rod 931 can be stably inserted into the inner cavity of the adjacent limiting hole 932, thereby improving the limiting effect on the knob 93.

[0031] Example 2

[0032] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 3 and Figure 5 The disassembly assembly 8 includes a support rod 81 rotatably connected to the middle position of the bottom of the groove cavity and a rotating gear 82 fixedly installed on the top of the support rod 81. Both sides of the rotating gear 82 are meshed with rack plates 83. A toggle plate 87 is fixedly installed on the top of the rack plate 83 on the other side. Bent rods A84 and B85 are fixedly installed on the bottom of the rack plate 83 respectively. Rectangular slots are opened on both the front and rear sides of the inner cavity of the slot. The ends of the bent rods A84 and B85 respectively movably penetrate the inner cavity of the adjacent rectangular slots and are fixedly installed with locking blocks 86. The opposite side of the locking blocks 86 is movably inserted into the inner cavity of the adjacent locking slots.

[0033] Specifically, when the arc block 7 needs to be replaced, with the cooperation of the disassembly assembly 8, when the adjacent rack plate 83 moves backward, the other rack plate 83 can move forward under the transmission of the rotating gear 82. With the connection of the adjacent bent rods A84 and B85, the two locking blocks 86 can move to the side away from each other, and thus move away from the inner cavity of the adjacent locking slot, which facilitates the replacement of the arc block 7. This makes the jack body 5 suitable for testing cylindrical objects of different sizes, and improves the range of use of the device.

[0034] Limiting telescopic rods 861 are fixedly installed on the opposite side of the locking block 86, and the opposite end of the limiting telescopic rods 861 is fixedly connected to the inner cavity of the adjacent rectangular groove.

[0035] Specifically, the limit telescopic rod 861 can support the locking block 86.

[0036] Each rack plate 83 has a compression telescopic rod 831 fixedly installed on the opposite end, and the opposite end of the compression telescopic rod 831 is fixedly connected to the inner wall of the adjacent groove cavity. Each compression telescopic rod 831 is movably sleeved with a compression spring 832, and the two ends of the compression spring 832 are fixedly connected to the adjacent rack plate 83 and the inner wall of the groove cavity, respectively.

[0037] Specifically, by setting up a compression telescopic rod 831 and a compression spring 832, the locking block 86 can be stably inserted into the inner cavity of the slot.

[0038] Working Principle: When using this invention, to test the horizontal thrust of the jack body 5, the jack body 5 is placed on the support block 4. Pulling the pull rod 931 forward moves the end of the pull rod 931 away from the inner cavity of the adjacent limiting hole 932. Rotating the knob 93 rotates the threaded rod 92 fixed to the knob 93. The threaded rod 92 has opposite external threads near its front and rear ends, with the same thread precision. During the rotation of the threaded rod 92, the threaded sleeve 94, threaded to the outer circumference of the threaded rod 92, moves to the opposite side under the limitation of the limiting block 941 and the limiting rod 942. Furthermore, with the connection of two adjacent connecting rods 95, the two clamping plates 96 move towards each other, thereby enabling the jack body to... 5. Limiting is implemented to prevent the jack body 5 from tilting or even falling off during the test, thereby improving the efficiency of subsequent horizontal thrust tests of the jack body 5. Different arc blocks 7 can be selected according to the size of the column. When replacing the arc block 7, the actuating plate 87 can be pushed backward to move the adjacent rack plate 83 fixed at the bottom of the actuating plate 87 backward. This allows the rotating gear 82 meshing with the adjacent rack plate 83 to rotate, thereby allowing the other rack plate 83 to move forward. With the connection of the adjacent bent rods A84 and B85, the two locking blocks 86 can move to the side away from each other, thereby moving away from the inner cavity of the adjacent locking slot, facilitating the replacement of the arc block 7. This allows the jack body 5 to be used for tests on columnar objects of different sizes, improving the range of applications of the device.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
