Description

Technical Field

[0001] This invention relates to the field of building testing technology, and more specifically to a horizontal static load testing device. Background Technology

[0002] Static load testing 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 pile top over time to determine the corresponding vertical compressive bearing capacity, vertical uplift bearing capacity, or horizontal bearing capacity of a single pile. When conducting horizontal static load tests with existing equipment, a large number of experimental instruments are required, including reaction devices, force measuring devices, load plates, and deformation measuring devices. Finally, statistical calculations are performed by a computer to record the horizontal static load test results.

[0003] In modern horizontal static load tests, jacks are required, and there are many experimental instruments and multiple sets of data cables nearby. In order to observe the connection of the experimental instruments and other conditions, adjustments need to be made during the test to make the experimental instruments face the observation position as much as possible. The adjustment needs to be done manually, that is, by manually installing and adjusting, and then various auxiliary tools are used to achieve the horizontal static load test.

[0004] However, in actual use, when adjustments are needed, people need to enter the horizontal static load test area to make adjustments. When entering, due to the large number of objects being pressed down and the limitations of the environment on site, each adjustment takes a lot of time, and the narrow space makes each adjustment very troublesome. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a horizontal static load detection device.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0007] This invention provides a horizontal static load testing device, including a jack, an outer shell provided on the outer wall of the jack, a guide groove provided on the outer shell, a buckle slidably engaged in the guide groove, a collar provided on the buckle, a hydraulic cylinder slidably engaged in the collar, the hydraulic cylinder and the jack are both connected to a hydraulic pump, and the buckle engagement testing device.

[0008] Furthermore, the bottom end of the outer shell is fixedly connected to the fixing plate, and the fixing plate is fixedly connected to the fixing plane; by setting the fixing plate, the outer shell is fixedly connected, and preferably the fixing plate cooperates with the jack.

[0009] Furthermore, the guide groove is provided with a first ball, and the buckle is provided with a slot that slides with the first ball; by providing the first ball and the slot, the guide groove and the buckle are matched. When the buckle is located in the guide groove, the buckle moves along the guide groove. The first ball reduces friction and wear when the buckle moves, thereby increasing the service life of the buckle and making the buckle move faster.

[0010] Furthermore, the buckle includes an engaging device and a moving rod. The engaging device engages with the detection device, and the moving rod cooperates with the first ball bearing. By setting the buckle structure, the buckle engages with the detection device and cooperates with the guide groove, thereby enabling the detection device to move along the guide groove. Thus, during adjustment, the experimental apparatus can be moved simply by moving the buckle, effectively improving the installation efficiency of horizontal static load testing.

[0011] Furthermore, the two ends of the slot are provided with second balls, which slide in contact with both the inner and outer walls of the outer casing. By providing the second balls, when the buckle moves in conjunction with the guide groove, the second balls make the buckle move more smoothly, thereby extending the buckle's service life.

[0012] Furthermore, the guide groove is spiral-shaped, and the starting point and the starting point of the guide groove are on the same plane. The thread inclination of the guide groove is greater than 45°. By setting the shape of the guide groove, when the buckle engages with the guide groove, the hydraulic cylinder moves upward, giving the buckle an upward force. The upward force is decomposed into an upward force and a horizontal force by the guide groove, thereby causing the buckle to move along the guide groove, thereby realizing the adjustment of the position of the detection device.

[0013] Furthermore, a retainer is provided at the bottom of the outer casing, which engages with the data cable. The height of the retainer is less than the height of the guide groove. By providing the retainer, the data cable can be engaged with the outer casing, so that the data cable will not obstruct the movement of the latch and the latch can move more quickly, thus enabling the detection device to move more quickly.

[0014] Furthermore, a limiting ring is fixedly connected to the upper end of the hydraulic cylinder. The limiting ring is sleeved on the outside of the jack, and the limiting ring and the collar slide together. By setting the limiting ring, when the hydraulic cylinder rises, the limiting ring rises accordingly. The collar that cooperates with the limiting ring exerts a vertical upward force, and the buckle is made to spiral up along the guide groove by the vertical upward force, thereby realizing the position adjustment of the detection device and effectively improving the installation efficiency of horizontal static load testing.

[0015] Furthermore, a connecting plate is fixedly connected to the outer wall of the housing, the connecting plate is fixedly connected to the hydraulic pump, and the connecting plate is fixedly connected to the mounting plane; by setting the connecting plate, the housing and the hydraulic pump are fixedly connected.

[0016] Furthermore, a mating plate is provided at the bottom of the jack, and the mating plate is fixedly connected to the hydraulic cylinder. Both the hydraulic cylinder and the jack are controlled by a PLC. By setting the mating plate, the linkage between the jack and the hydraulic cylinder can be realized. The hydraulic pressure of different hydraulic devices can be controlled by the PLC, thereby realizing the horizontal static load test and adjustment of the detection device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This device, through its outer casing and spiral guide groove, applies a vertically upward force to the latch. This upward force causes the latch to spiral upward along the guide groove, thus eliminating the need for manual close-range adjustment tools during horizontal static load testing. This reduces the installation time for horizontal static load testing and effectively improves the installation efficiency. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] This invention provides a horizontal static load detection device, with reference to Figure 1-6 It includes a jack 1, an outer shell 2 on the outer wall of the jack 1, a guide groove 3 on the outer shell 2, a buckle 4 slidingly fitted inside the guide groove 3, a collar 5 on the buckle 4, a hydraulic cylinder 6 slidingly fitted to the collar 5, the hydraulic cylinder 6 and the jack 1 are both connected to a hydraulic pump 7, and the buckle 4 engages the testing device.

[0032] The bottom end of the outer shell 2 is fixedly connected to the fixing plate 8, and the fixing plate 8 is fixedly connected to the fixing plane. By setting the fixing plate 8, the outer shell 2 is fixedly connected, and preferably the fixing plate 8 is matched with the jack 1.

[0033] The guide groove 3 is provided with a first ball bearing 9, and the buckle 4 is provided with a groove 10 that slides with the first ball bearing 9. By setting the first ball bearing 9 and the groove 10, the guide groove 3 and the buckle 4 are matched. When the buckle 4 is located in the guide groove 3, the buckle 4 moves along the guide groove 3. The first ball bearing 9 reduces friction and wear when the buckle 4 moves, thereby increasing the service life of the buckle 4 and making the buckle 4 move faster.

[0034] The buckle 4 includes a locking device 11 and a moving rod 12. The locking device 11 engages with the detection device, and the moving rod 12 cooperates with the first ball bearing 9. By setting the structure of the buckle 4, the buckle 4 can engage with the detection device and cooperate with the guide groove 3, thereby enabling the detection device to move along the guide groove 3. Thus, during adjustment, the experimental apparatus can be moved simply by moving the buckle 4, effectively improving the installation efficiency of the horizontal static load test.

[0035] The slot 10 has a second ball bearing 13 at both ends. The second ball bearing 13 slides in contact with both the inner wall and the outer wall of the outer shell 2. By setting the second ball bearing 13, when the buckle 4 moves in conjunction with the guide groove 3, the second ball bearing 13 makes the buckle 4 move more smoothly, thereby increasing the service life of the buckle 4.

[0036] The guide groove 3 is spiral-shaped, and the starting point and the starting point of the guide groove 3 are on the same plane. The inclination of the thread of the guide groove 3 is greater than 45°. By setting the shape of the guide groove 3, when the buckle 4 is engaged with the guide groove 3, the hydraulic cylinder 6 moves upward, giving the buckle 4 a vertical upward force. The vertical upward force causes the buckle 4 to move along the guide groove 3, thereby realizing the adjustment of the position of the detection device.

[0037] The bottom of the outer casing 2 is provided with a retainer 14, which is engaged with the data cable. The height of the retainer 14 is less than the height of the guide groove 3. By setting the retainer 14, the data cable is engaged with the outer casing 2, so that the data cable will not obstruct the movement of the latch 4, and the latch 4 moves more quickly, thus making the detection device move more quickly.

[0038] The upper end of the hydraulic cylinder 6 is fixedly connected to a limiting ring 15, which is sleeved on the outside of the jack 1. The limiting ring 15 and the collar 5 are in sliding fit. By setting the limiting ring 15, when the hydraulic cylinder 6 rises, the limiting ring 15 rises accordingly. The collar 5, which is in fit with the limiting ring 15, exerts an upward force. The buckle 4 decomposes the upward force into an upward force and a horizontal force, thereby realizing the buckle 4 spiraling up along the guide groove 3, and then realizing the position adjustment of the detection device, which effectively improves the installation efficiency of the horizontal static load test.

[0039] The outer wall of the outer shell 2 is fixedly connected to a connecting plate 16, which is fixedly connected to the hydraulic pump 7 and to the mounting plane. By setting the connecting plate 16, the outer shell 2 and the hydraulic pump 7 are fixedly connected.

[0040] The bottom end of the jack 1 is provided with a mating plate 17, which is fixedly connected to the hydraulic cylinder 6. Both the hydraulic cylinder 6 and the jack 1 are controlled by a PLC. By setting the mating plate 17, the linkage between the jack 1 and the hydraulic cylinder 6 can be realized. The hydraulic pressure of different hydraulic devices can be controlled by the PLC, thereby realizing the horizontal static load test and adjustment of the detection device.

[0041] Working principle: This device uses a housing 2 and a spiral guide groove 3 to apply an upward force to the buckle 4. The upward force is decomposed into an upward force and a horizontal force by the guide groove 3, which causes the buckle 4 to move along the guide groove 3, thereby adjusting the position of the detection device. The upward force can also be raised by the hydraulic cylinder 6, which raises the limiting ring 15 accordingly. The collar 5, which cooperates with the limiting ring 15, exerts an upward force, and the buckle 4 decomposes the upward force into an upward force and a horizontal force, thus enabling the buckle 4 to spiral up along the guide groove 3, thereby effectively improving the installation efficiency of horizontal static load testing.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
