Description

Technical Field

[0001] This utility model relates to the field of sheet pile testing technology, and in particular to a sheet pile torsion testing device. Background Technology

[0002] Sheet piles are steel structures with interlocking devices on their edges, which can be freely combined to form a continuous and tight retaining wall or water-retaining wall. The structure of a sheet pile generally consists of a web, two inclined side plates at both ends of the web, and a locking mechanism at one end of each side plate. When sheet piles are inserted into the soil for retaining, the stress conditions are complex, and the sheet piles may twist under soil compression. Therefore, to test the torsional force that sheet piles can withstand and the number of times they can be used under torsional conditions, a torsion test needs to be performed before the sheet piles leave the factory. However, because the cross-sectional shape of sheet piles is irregular, there are no special clamps to hold them, making it impossible to perform a torsion test on sheet piles. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a steel sheet pile torsion testing device.

[0016] 1. In this utility model, the two ends of the steel sheet pile are respectively fixed and clamped between the first clamping block and the second clamping block, and the first clamping block and the second clamping block are locked and fixed. Then, the gear ring is sleeved on the outside of the first clamping block and the second clamping block.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 As shown, a sheet pile torsion testing device includes a support 1. Clamping components are rotatably mounted on both the upper and lower ends of the support 1. A gear ring 2 is fitted on the clamping components. The gear ring 2 is detachably and fixedly connected to the clamping components. The outer circumference of the gear ring 2 is provided with teeth. A motor 3 is fixedly mounted on the support 1. At least two motors 3 are provided. Multiple motors 3 are evenly distributed on the upper and lower ends of the support 1. The motors 3 located at the upper and lower ends of the support 1 rotate in opposite directions. A gear 4 is fixedly mounted on the output shaft of the motor 3. The motor 3 can drive the gear 4 to rotate. The gear 4 meshes with the gear ring 2. In this invention, the upper and lower ends of the sheet pile are respectively fixed to clamping assemblies at the upper and lower ends of the support 1. The clamping assemblies clamp and fix the sheet pile. Then, the motor 3 is started to rotate the gear 4, and the gear ring 2 meshing with the gear 4 rotates synchronously, thereby enabling the clamping assembly and the sheet pile fixed on the clamping assembly to rotate. Since the upper and lower ends of the support 1 are both equipped with motors 3 and rotate in opposite directions, the upper and lower ends of the sheet pile can be twisted in opposite directions, thereby causing the sheet pile to twist. Then, a torsion test is performed on the sheet pile. During the test, the torsion angle of the sheet pile can be controlled by controlling the rotation angle of the output shaft of the motor 3, and multiple torsion angle tests are performed on the sheet pile.

[0029] Furthermore, such as Figure 1 As shown, the support 1 includes a base plate 5 and a top plate 6, which are arranged in parallel. Multiple first guide rods 7 are fixedly installed on the edge of the base plate 5. The first guide rods 7 are vertically arranged, and the top plate 6 is slidably installed on the first guide rods 7. The outer wall of the first guide rods 7 is marked with a scale along the length direction to mark the height of the top plate 6. A lead screw 8 is rotatably installed on the base plate 5, and a lead screw nut is installed on the top plate 6. The lead screw nut on the top plate 6 is threadedly connected to the lead screw 8. The top plate 6 can be raised or lowered by rotating the lead screw 8, thereby adjusting the distance between the base plate 5 and the top plate 6 to accommodate steel sheet piles of different lengths. Clamping assemblies are rotatably installed on the base plate 5 and the top plate 6 respectively. Similarly, a motor 3 is fixedly installed on the base plate 5 and the top plate 6 to drive the clamping assemblies to rotate on the base plate 5 and the top plate 6, causing the steel sheet pile to twist.

[0030] In one embodiment, such as Figure 2and Figure 3 As shown, the clamping assembly includes a first clamping block 9 and a second clamping block 10. Both the first clamping block 9 and the second clamping block 10 have a semi-circular structure. The first clamping block 9 is provided with a locking block 11. The two side walls of the locking block 11 are inclined and adapted to the inclination angle of the two side plates of the steel sheet pile. The second clamping block 10 is provided with a locking groove 12. The two side walls of the locking groove 12 are inclined and adapted to the inclination angle of the two side plates of the steel sheet pile. When the first clamping block 9 and the second clamping block 10 are closed, the locking block 11 is locked in the locking groove 12 to clamp the steel sheet pile. The toothed ring 2 is sleeved on the first clamping block 9 and the second clamping block 10. In this embodiment, the end of the sheet pile is positioned between the first clamping block 9 and the second clamping block 10. As the first clamping block 9 and the second clamping block 10 close, the sheet pile is clamped in the slot 12. The side wall of the slot 12 is in contact with the sheet pile. At the same time, when the clamping block 11 is clamped in the slot 12, it can clamp and fix the sheet pile. When the first clamping block 9 and the second clamping block 10 close, they form a circular structure. Then, the gear ring 2 is sleeved on the outside of the first clamping block 9 and the second clamping block 10. The gear ring 2 meshes with the gear 4. As the gear 4 drives the gear ring 2 to rotate, the end of the sheet pile rotates, thereby performing a torsion test on the sheet pile.

[0031] Furthermore, a first clearance groove 26 is provided at one end of the slot 12 near the first clamping block 9, and a second clearance groove 27 is provided at the bottom end of the slot 11. When the first clamping block 9 and the second clamping block 10 are closed, the first clearance groove 26 and the second clearance groove 27 are connected. The locking port on the sheet pile is located inside the first clearance groove and the second clearance groove to prevent the locking port from interfering with the first locking block 9 and the second locking block 10.

[0032] Furthermore, the thickness of the first clamping block 9 and the second clamping block 10 is greater than the thickness of the toothed ring 2. When the toothed ring 2 is fitted onto the first clamping block 9 and the second clamping block 10, the toothed ring 2 is located on the upper part of the first clamping block 9 and the second clamping block 10. Rotation holes are provided on the bottom plate 5 and the top plate 6. The lower parts of the first clamping block 9 and the second clamping block 10 are rotatably set in the rotation holes. At this time, the toothed ring 2 can also prevent the first clamping block 9 and the second clamping block 10 from falling out of the rotation holes.

[0033] Furthermore, multiple limiting grooves 13 are evenly provided on the outer circular surfaces of the first clamping block 9 and the second clamping block 10, and multiple limiting blocks 14 are provided on the inner ring of the gear ring 2. The limiting blocks 14 are locked in the limiting grooves 13, which can prevent relative rotation between the gear ring 2 and the first clamping block 9 and the second clamping block 10.

[0034] Furthermore, the first clamping block 9 and the second clamping block 10 are fixedly connected by multiple connecting plates 15. Specifically, threaded holes are provided on the upper end faces of both the first clamping block 9 and the second clamping block 10, and two bolts are rotatably provided on the connecting plate 15. One bolt on the connecting plate 15 is threadedly connected to the threaded hole on the first clamping block 9, and the other bolt is threadedly connected to the threaded hole on the second clamping block 10, thereby fixing the first clamping block 9 and the second clamping block 10 together.

[0035] In another embodiment, such as Figure 4 and Figure 5 As shown, the clamping assembly includes a clamping plate 16, which is circular in structure and rotatably mounted on the bracket 1. A toothed ring 2 is fitted onto the outer circular surface of the clamping plate 16. A clamping groove 17 is formed in the middle of the clamping plate 16. An outer clamping block 18, a web clamping block 19, and an inner clamping block 20 are provided in the clamping groove 17. The outer clamping blocks 18 are horizontally slidably disposed in the clamping groove 17. There are two outer clamping blocks 18, which are symmetrically arranged along the vertical center plane of the clamping plate 16. The two outer clamping blocks 18 can slide towards each other or away from each other. The sides of the sheet pile are inclined and close to each other, which is adapted to the two side walls of the sheet pile. The web clamping block 19 is horizontally slidably disposed between the two outer clamping blocks 18. The sliding direction of the web clamping block 19 is perpendicular to the sliding direction of the outer clamping block 18. The inner clamping block 20 is horizontally slidably disposed on the web clamping block 19. There are two inner clamping blocks 20, which are symmetrically disposed along the vertical center plane of the clamping plate 16. The two inner clamping blocks 20 can slide in a direction that is close to or far away from each other. The sides of the two inner clamping blocks 20 close to the outer clamping blocks 18 are inclined and adapted to the two side walls of the sheet pile.

[0036] In this embodiment, the end of the sheet pile is placed in the clamping groove 17, and two outer clamping blocks 18 are located on both sides of the sheet pile. As the two outer clamping blocks 18 slide towards each other, the two sides of the sheet pile can be clamped. At the same time, the web clamping block 19 slides towards the side of the sheet pile to clamp the inner web of the sheet pile, while the two inner clamping blocks 20 slide away from each other to clamp and fix the two side walls of the sheet pile. With the combined action of the outer clamping blocks 18, the web clamping blocks 19 and the inner clamping blocks 20, the end of the sheet pile is clamped and fixed.

[0037] Furthermore, clearance grooves are provided on the sides of the outer clamping blocks 18 that are close to each other, and the locking jaws of the sheet piles are locked in the clearance grooves to prevent the locking jaws from interfering with the outer clamping blocks 18.

[0038] Furthermore, the thickness of the clamping plate 16 is greater than the thickness of the toothed ring 2. After the toothed ring 2 is fitted onto the clamping plate 16, the toothed ring 2 is located on the upper part of the clamping plate 16. Rotation holes are provided on the bottom plate 5 and the top plate 6. The lower part of the clamping plate 16 is rotatably set in the rotation hole. The toothed ring 2 can prevent the clamping plate 16 from falling out of the rotation hole.

[0039] Furthermore, multiple limiting grooves 13 are evenly provided on the outer circular surface of the clamping plate 16 along the circumferential direction, and multiple limiting blocks 14 are evenly provided on the inner circular surface of the gear ring 2 along the circumferential direction. When the gear ring 2 is fitted onto the clamping plate 16, the limiting blocks 14 are locked in the limiting grooves 13 to prevent relative rotation between the gear ring 2 and the clamping plate 16.

[0040] Furthermore, a first threaded post 21 and a second threaded post 22 are rotatably disposed on the clamping plate 16. Both the first threaded post 21 and the second threaded post 22 are horizontally disposed within the clamping groove 17, and their length directions are perpendicular. The first threaded post 21 is threadedly connected to the outer clamping block 18, and the outer clamping block 18 slides within the clamping groove 17 by rotating the first threaded post 21. The second threaded post 22 is threadedly connected to the web clamping block 19, and the web clamping block 19 slides within the clamping groove 17 by rotating the second threaded post 22. A third threaded post 23 is disposed between the two inner clamping blocks 20. The third threaded post 23 has bidirectional threads and is threadedly connected to the two inner clamping blocks 20 respectively. Therefore, when the third threaded post 23 is rotated, the two inner clamping blocks 20 can slide in a direction that moves closer to each other or further away from each other.

[0041] Furthermore, fixing blocks 28 are fixedly installed on the first threaded post 21, the second threaded post 22, and the third threaded post 23. The fixing blocks 28 have a hexagonal structure, which facilitates clamping with a wrench. By clamping the fixing blocks 28 with a wrench, the first threaded post 21, the second threaded post 22, and the third threaded post 23 can be rotated. The fixing block 28 on the third threaded post 23 is located in the middle of the third threaded post 23. In addition, locking nuts 29 are threadedly connected to the first threaded post 21, the second threaded post 22, and the third threaded post 23. Two locking nuts 29 are symmetrically provided on the third threaded post 23. After the positions of the outer clamping block 18, the web clamping block 19, and the inner clamping block 20 are adjusted, the locking nuts 29 can be rotated to lock and fix the outer clamping block 18, the web clamping block 19, and the inner clamping block 20.

[0042] Furthermore, such as Figure 5 As shown, a slide bar 24 is provided on the web clamping block 19, and a slide groove 25 is provided on the inner clamping block 20. The slide bar 24 is located in the slide groove 25 and is limited when the inner clamping block 20 slides along the upper end face of the web clamping block 19, so that the inner clamping block 20 can only slide along the length direction of the slide bar 24.

[0043] Furthermore, a second guide rod 30 and a third guide rod 31 are fixedly installed in the clamping groove 17. The second guide rod 30 is arranged parallel to the first threaded post 21, and the outer clamping block 18 is slidably disposed on the second guide rod 30. The third guide rod 31 is arranged parallel to the second threaded post 22, and the web clamping block 19 is slidably disposed on the third guide rod 31, which can prevent the outer clamping block 18 and the web clamping block 19 from rotating in the clamping groove 17.

[0044] Furthermore, the thickness of the web clamping block 19 is less than the thickness of the outer clamping block 18.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
