Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of plate load testing equipment, and more specifically, to a conveniently adjustable plate load testing equipment for road design. Background Technology

[0002] The plate load tester is a core piece of equipment in the field of civil engineering used to determine the bearing capacity of foundation soil, pavement materials, etc. It can be used to test the subgrade coefficient of coarse soil, fine soil and compacted soil subgrade, base course, etc., and is one of the most commonly used testing equipment.

[0003] In existing technologies, traditional plate load testers typically consist of a load plate, a spirit level, a jack, and dial indicators. The general workflow involves placing the load plate on the ground to be tested, positioning the spirit level on one side of the load plate via a support column, ensuring the spirit level is horizontal, adjusting the dial indicator brackets so that each dial indicator's measuring head is in contact with the upper surface of the spirit level, zeroing the dial indicators, and finally, pressing a manual oil pump to pressurize the jack. When the pressure displayed by the manual oil pump reaches the predetermined pressure, the operator records the dial indicator reading. However, due to varying application locations, the load plate may tilt due to uneven ground, and the support column may also be tilted, making it difficult to keep the spirit level. In such cases, the operator may try laying and compacting soil under the load plate and support column, but this requires multiple attempts, has low accuracy, and is inefficient. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a conveniently adjustable plate load testing instrument for road design, which solves the technical problem in the prior art that adjusting the level of the load plate and spirit level requires multiple attempts, and has low accuracy and low efficiency, when laying and compacting soil layers under the load plate and support columns.

[0005] According to one aspect, at least one embodiment of this disclosure provides a road design plate load testing apparatus that is easy to adjust, including an apparatus body. The apparatus body includes a load plate and a level. A jack is detachably mounted on the top of the load plate. The level is mounted on one side of the jack and above the load plate. The apparatus also includes a fixing component and four support adjustment components. The fixing component is mounted on the level and is used to detachably fix the level to the outer wall of the jack. The four support adjustment components are all mounted on the outer wall of the load plate via quick-release components and are used to support and adjust the height of the four corners of the load plate.

[0006] Preferably, in order to allow the level to be detachably fixed to the outer wall of the jack for easy measurement of whether the load plate is level and for subsequent adjustment, the fixing assembly includes a connecting plate, two first rotating shafts, two rotating plates, two clamping plates, and a first bolt. One end of the connecting plate is fixedly connected to one end of the level. Two slots are provided on the connecting plate. The two ends of the first rotating shafts are fixedly connected to the inner top wall and inner bottom wall of the slots, respectively. One end of the rotating plate is sleeved on the first rotating shaft and is rotatably connected to the first rotating shaft. One end of the clamping plate is fixedly connected to the other end of the rotating plate. The two clamping plates are detachably connected by the first bolt.

[0007] Furthermore, in order to make the four support adjustment components detachably connected to the four corners of the load plate for easy transportation and space saving, the quick-release component includes a fixing plate and a second bolt. The load plate has a slot that mates with the fixing plate. One end of the fixing plate slides into the slot. One end of the second bolt passes through the load plate and the fixing plate in sequence. Both the load plate and the fixing plate are threadedly connected to the first bolt.

[0008] Furthermore, in order to adjust the height of the fixed plate, the support adjustment assembly includes a threaded cylinder and a support plate. The threaded cylinder is disposed on one side of the load plate, and a threaded groove is formed on the inner side wall of the threaded cylinder. One end of the support plate is hinged to the other end of the fixed plate through a hinge member. A sliding groove is formed on the threaded cylinder to cooperate with the support plate. The support plate slides in cooperation with the sliding groove through a driving member.

[0009] As a further aspect of this application, in order to prevent obstruction and deformation of the fixed plates when the load plate is tilted and the support plate moves up and down after the load plate is connected by the four fixed plates, the hinge includes a connecting seat and a second rotating shaft. One end of the connecting seat is fixedly connected to one end of the support plate, and the other end of the connecting seat is provided with a through groove. The two ends of the second rotating shaft are respectively fixedly connected to the two inner side walls of the through groove, and the other end of the fixed plate is rotatably connected to the second rotating shaft.

[0010] As a further embodiment of this application, in order to drive the support plate to move up and down along the inner wall of the slide groove, the driving component includes a stud, a connecting shaft, a rotating rod, and a knob. The stud is disposed inside the threaded cylinder and threadedly connected to the threaded cylinder. The top end of the connecting shaft is rotatably connected to the stud on the same axis. The outer side wall of the connecting shaft is fixedly connected to the other end of the support plate. One end of the rotating rod is fixedly connected to one end of the stud on the same axis. One end of the knob is fixedly connected to the other end of the rotating rod on the same axis.

[0011] Based on the aforementioned scheme, in order to stably clamp and wrap the outer wall of the jack with the two clamping plates, an arc-shaped groove is provided on the outer wall of the clamping plate, and the inner sidewall of the two arc-shaped grooves is in contact with the outer wall of the jack.

[0012] Furthermore, to avoid collisions and friction between the connecting shaft and the threaded groove, the cross-sectional area of ​​the threaded groove is larger than the cross-sectional area of ​​the connecting shaft.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] 1. In this disclosure, by setting a fixing component, moving one end of the two clamping plates causes the clamping plates to rotate around the axis of the first rotating shaft. The outer wall of the jack is clamped by the arc groove in the two clamping plates. At this time, the two clamping plates "overlap". The two clamping plates are threadedly fixed by the first bolt. In this way, the level is fixed above the load plate while maintaining "parallel" to the load plate. Accurate data can be provided while adjusting the angle of the load plate.

[0015] 2. In this disclosure, by providing a support adjustment component, the load plate and the fixing plate are fixed by the second bolt through threads. This allows multiple support adjustment components to be removed from or installed on the load plate, facilitating subsequent transportation and transfer.

[0016] The testing instrument is placed on a non-flat test surface, causing the load plate and the level fixed above the load plate to be tilted. The fixed plate, under the weight of the load plate, partially tilts and rotates around a second pivot to accommodate the tilted load plate. By observing the tilt and offset angles of the load plate, the corresponding knobs are turned to drive the support plate downwards along the inner wall of the chute. The data on the level indicates whether the load plate and level are level. Subsequent testing is then performed by laying and compacting soil under the load plate and support column to adjust the level of the load plate and level. This method offers high accuracy and efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on this disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-6 As shown, it illustrates a road design plate load tester that is easy to adjust according to an embodiment of the present disclosure. The tester includes a tester body, which includes a load plate 2 and a level 3. A jack 4 is detachably provided on the top of the load plate 2. The jack 4 is vertically provided on the top of the load plate 2. The level 3 is provided on one side of the jack 4 and above the load plate 2. The tester also includes a fixing component and four support and adjustment components.

[0032] like Figure 3 and Figure 5As shown, the fixing assembly is set on the level ruler 3, used to detachably fix the level ruler 3 to the outer wall of the jack 4. In order to detachably fix the level ruler 3 to the outer wall of the jack 4 horizontally, to facilitate the measurement of whether the load plate 2 is horizontal, and to facilitate subsequent adjustment, the fixing assembly includes a connecting plate 5, two first rotating shafts, two rotating plates 8, two clamping plates 9, and a first bolt 10. One end of the connecting plate 5 is fixedly connected to one end of the level ruler 3. Two slots 7 are opened on the connecting plate 5. The two ends of the first rotating shafts are fixedly connected to the inner top wall and inner bottom wall of the slots 7, respectively. One end of the rotating plate 8 is sleeved on the first rotating shaft, and the rotating plate 8 is rotatably connected to the first rotating shaft. One end of the clamping plate 9 is fixedly connected to the other end of the rotating plate 8. In order to stably clamp and wrap the outer wall of the jack 4 with the two clamping plates 9, the clamping plates 9... An arc-shaped groove 24 is provided on the outer side wall of the jack 4. The inner side walls of the two arc-shaped grooves 24 are in contact with the outer side wall of the jack 4. The two clamping plates 9 are detachably connected by the first bolt 10. By holding the level ruler 3 and moving the connecting plate 5, the connecting plate 5 moves the rotating plate 8, the clamping plate 9 and the first rotating shaft, moving the two clamping plates 9 to the outer side wall of the jack 4 and making the two clamping plates 9 "encircle" the jack 4. By rotating one end of the two clamping plates 9, the clamping plates 9 rotate around the axis of the first rotating shaft. The outer side wall of the jack 4 is clamped by the arc-shaped grooves 24 in the two clamping plates 9. At this time, the two clamping plates 9 "overlap". The two clamping plates 9 are threadedly fixed by the first bolt 10. In this way, the level ruler 3 is fixed above the load plate 2 while maintaining "parallel" to the load plate 2.

[0033] like Figure 2 , Figure 4 and Figure 6 As shown, four support adjustment components are all mounted on the outer wall of the load plate 2 via quick-release components. They are used to support and adjust the height of the four corners of the load plate 2. In order to make the four support adjustment components detachably connected to the four corners of the load plate 2, it is convenient for transportation and saves space. The quick-release components include a fixing plate 11 and a second bolt 13. The load plate 2 has a slot 12 that mates with the fixing plate 11. One end of the fixing plate 11 slides into the slot 12. One end of the second bolt 13 passes through the load plate 2 and the fixing plate 11 in sequence. The load plate 2 and the fixing plate 11 are both threadedly connected to the first bolt 10. By moving the support adjustment components and inserting one end of the fixing plate 11 into the slot 12, and then fixing the load plate 2 and the fixing plate 11 with the second bolt 13, multiple support adjustment components can be removed or installed from the load plate 2, which is convenient for subsequent transportation and transfer.

[0034] To adjust the height of the fixed plate 11, the support adjustment assembly includes a threaded cylinder 14 and a support plate 16. The threaded cylinder 14 is located on one side of the load plate 2, and a base is provided at the bottom end of the threaded cylinder 14. A threaded groove 15 is formed on the inner side wall of the threaded cylinder 14. One end of the support plate 16 is hinged to the other end of the fixed plate 11 via a hinge. A sliding groove 17 is formed on the threaded cylinder 14 to cooperate with the support plate 16. The support plate 16 slides in cooperation with the sliding groove 17 via a driving member. To prevent obstruction and deformation of the fixed plate 11 when the load plate 2 is connected by four fixed plates 11 and when the load plate 2 tilts or the support plate 16 moves up and down, the hinge includes a connecting seat 18 and a second rotating... Shaft 19, one end of connecting seat 18 is fixedly connected to one end of support plate 16, the other end of connecting seat 18 is provided with through groove, the two ends of second rotating shaft 19 are respectively fixedly connected to the two inner side walls of through groove, the other end of fixing plate 11 is rotatably connected to second rotating shaft 19. After multiple threaded cylinders 14 are placed on the ground to be measured, the ground may not be flat, which may cause the bottom ends of multiple threaded cylinders 14 to not be on the same horizontal line, so that load plate 2 and level 3 fixed above load plate 2 are tilted. Then the fixing plate 11 is subjected to the gravity of load plate 2, causing part of the fixing plate 11 to tilt and rotate with second rotating shaft 19 as the center, so as to adapt to the tilted state of load plate 2.

[0035] To drive the support plate 16 to move up and down along the inner wall of the slide groove 17, a telescopic mesh cover 25 is provided on the bottom end of the support plate 16 and the inner bottom wall of the slide groove 17. The driving components include a stud 20, a connecting shaft 21, a rotating rod 22, and a knob 23. The stud 20 is disposed inside the threaded cylinder 14 and threadedly connected to the threaded cylinder 14. The top end of the connecting shaft 21 is coaxially and rotatably connected to the stud 20. The outer side wall of the connecting shaft 21 is fixedly connected to the other end of the support plate 16. To avoid collision and friction between the connecting shaft 21 and the threaded groove 15, the threaded groove 15... The cross-sectional area is larger than that of the connecting shaft 21. One end of the rotating rod 22 is coaxially and fixedly connected to one end of the stud 20. One end of the knob 23 is coaxially and fixedly connected to the other end of the rotating rod 22. Before the fixing plate 11 is fixed to the load plate 2, the stud 20 is always threadedly connected to the threaded cylinder 14. When the load plate 2 and the level 3 above it are tilted, the multiple studs 20 remain stable while the load plate 2 drives part of the fixing plate 11 to rotate and tilt around the second rotating shaft 19. This can be observed by looking at the load plate 2. The tilt angle and offset angle are adjusted by rotating the corresponding knob 23. Rotating the knob 23 causes the rotating rod 22 to rotate, which in turn causes the stud 20 to rotate. During rotation, the stud 20 moves downward along the threaded groove 15. The downward movement of the stud 20 causes the connecting shaft 21 to move downward. Since a support plate 16 is fixedly connected to the outer wall of the connecting shaft 21, the connecting shaft 21 causes the support plate 16 to move downward along the inner wall of the slide groove 17. The cooperation between the support plate 16 and the slide groove 17 can play a guiding role and prevent the connecting shaft 21 from rotating. During the rotation of the knob 23, the load plate 2 and the level 3 shift at an angle. By observing the data on the level 3, it can be shown whether the load plate 2 and the level 3 are in a horizontal state. Depending on the real-time situation, the corresponding stud 20 of the fixed plate 11 at the higher position can be adjusted to move downward, or the fixed plate 11 at the lower position can be adjusted to move upward toward the corresponding stud 20. By driving the support plate 16 to move until the load plate 2 and the level 3 are in a horizontal state, the subsequent work of the testing instrument body can be carried out.

[0036] Working principle: Before using this easily adjustable road design plate load tester, hold the level 3 and move the connecting plate 5. The connecting plate 5 moves the rotating plate 8, clamping plate 9 and the first rotating shaft. Move the two clamping plates 9 to the outer wall of the jack 4 and make the two clamping plates 9 "encircle" the jack 4. By rotating one end of the two clamping plates 9, the clamping plates 9 rotate around the axis of the first rotating shaft. The outer wall of the jack 4 is clamped by the arc groove 24 in the two clamping plates 9. At this time, the two clamping plates 9 "overlap". The two clamping plates 9 are threaded and fixed by the first bolt 10. In this way, the level 3 is fixed above the load plate 2 while keeping it "parallel" to the load plate 2. Then, the load plate 2 and the fixing plate 11 are threaded and fixed by the second bolt 13. This allows multiple support adjustment components to be removed or installed from the load plate 2, which is convenient for subsequent transportation and transfer.

[0037] After assembly, the easily adjustable road design plate load tester is placed on the ground to be tested. The ground may not be flat, causing the load plate 2 and the level 3 fixed above the load plate 2 to be tilted. The fixed plate 11, under the weight of the load plate 2, partially tilts and rotates around the second pivot 19 to accommodate the tilted state of the load plate 2. While the multiple studs 20 remain stable, the load plate 2 drives part of the fixed plate 11 to rotate and tilt around the second pivot 19. The corresponding knob 23 can be rotated based on the observed tilt and offset angles of the load plate 2. Rotating the knob 23 causes the rotating rod 22 to rotate, which in turn drives the studs 20 to rotate. During rotation, the studs 20 move downwards along the threaded groove 15, causing the connecting shaft 21 to move downwards. Due to the outer wall of the connecting shaft 21... A support plate 16 is fixedly connected, and the connecting shaft 21 drives the support plate 16 to move downward along the inner wall of the slide groove 17. The cooperation between the support plate 16 and the slide groove 17 can play a guiding role and prevent the connecting shaft 21 from rotating. During the rotation of the knob 23, the load plate 2 and the level 3 will shift at an angle. By observing the data on the level 3, it can be shown whether the load plate 2 and the level 3 are in a horizontal state. Depending on the real-time situation, the corresponding stud 20 of the fixed plate 11 at the higher position can be adjusted to move downward, or the fixed plate 11 at the lower position can be adjusted to move upward toward the corresponding stud 20. By driving the support plate 16 to move until the load plate 2 and the level 3 are in a horizontal state, the subsequent work of the testing instrument body can be carried out. By comparing the adjustment of the horizontal state of the load plate 2 and the level 3 by laying and compacting the soil layer under the load plate 2 and the support column, the accuracy is high and the efficiency is high.
