Description

Technical Field

[0001] This invention relates to the field of sheet pile positioning technology, and in particular to a positioning and guiding device for sheet piles. Background Technology

[0002] Sheet piles are a type of steel with interlocking joints, and are often used to make cofferdams.

[0003] For example, a mobile sheet pile positioning and guiding device was disclosed on September 16, 2022, with publication number CN217438929U. This device includes a mobile frame and a limiting structure. The mobile frame includes a base plate and a top plate connected to the base plate via connecting columns. The limiting structure is a limiting channel that runs through the top plate and the base plate. The shape of the limiting channel is adapted to the shape of the sheet pile. Moving blocks and fixed blocks are provided on both sides of the limiting channel. The moving blocks and fixed blocks are interlocked according to the shape of the sheet pile, and the gap between them forms the sheet pile limiting channel. This invention greatly improves the installation efficiency of sheet piles by pushing the mobile frame to install them sequentially. However, it can only position and guide one sheet pile at a time. Before driving the next sheet pile, the driving position needs to be positioned and guided again, resulting in low construction efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a positioning and guiding device for steel sheet piles to solve the problem of low construction efficiency.

[0005] To achieve the above objectives, the present invention provides a positioning and guiding device for sheet piles, comprising two fixed blocks connected by a first connecting plate. One fixed block is provided with a first bracket perpendicular to the first connecting plate, and the other fixed block is provided with a second bracket parallel to the first bracket. The second bracket is slidably connected to two sliders symmetrically arranged about the fixed blocks. The first bracket is provided with a second moving member, which is connected to two support blocks symmetrically arranged about the fixed blocks. The second moving member is used to control the two support blocks to move towards or away from each other. The support blocks are connected to a second connecting plate parallel to the first connecting plate. The other end of the second connecting plate is connected to the sliders. Each second connecting plate is provided with a forward and backward moving member, and the first connecting plate is provided with two forward and backward moving members. The forward and backward moving members are connected to clamping members, which are used to control the forward and backward movement of the clamping members. The two clamping members on the first connecting plate face opposite directions. The clamping members are used to clamp the sheet pile placed between the first and second connecting plates.

[0006] Optionally, the second moving part includes a second control component located on the first bracket. The second control component is connected to a second threaded rod. The second control component is used to control the rotation of the second threaded rod. The second threaded rod is provided with two second threaded segments with opposite thread directions. The two second threaded segments are located on both sides of the fixed block. The support block is sleeved on the second threaded segments. The first bracket is provided with a slide rail that is slidably connected to the support block.

[0007] Optionally, the fixing block has a through-hole extending vertically, and an anchor pile is installed in the through-hole. The lower end face of the fixing block has a groove located on both sides of the through-hole. A lifting cylinder is installed in the groove, and a roller is connected to the telescopic end of the lifting cylinder.

[0008] Optionally, a plurality of first guide wheels are provided on the side wall of the anchor hole.

[0009] Optionally, the clamping component includes a base, on which a hollow sleeve is connected. A movable rod passing through the sleeve is connected to the base via a telescopic drive component. A connecting frame is provided at the end of the sleeve away from the base. Two symmetrically arranged sector gears are rotatably connected to the connecting frame. The sector gears are rotatably connected to the connecting frame via a rotating shaft. A swing rod is connected to each of the two sector gears. The two swing rods are symmetrically arranged about the movable rod. An annular rack groove that meshes with the sector gear is provided on the outer wall of the movable rod. A pressure guide wheel is provided at the end of the swing rod away from the base and at the end of the movable rod away from the base.

[0010] Optionally, a plurality of second guide wheels are provided on the sidewalls of the first connecting plate and the second connecting plate.

[0011] Optionally, both the first connecting plate and the second connecting plate are long vertical plates.

[0012] Optionally, the first support is provided with a first movable component, which is connected to two sag detectors symmetrically arranged about the fixed block. The first movable component is used to control the two sag detectors to move towards or away from each other.

[0013] Optionally, the first moving part includes a first control component located on the first bracket. The first control component is connected to a first threaded rod. The first control component is used to control the rotation of the first threaded rod. The first threaded rod is provided with two first threaded segments with opposite thread directions. The two first threaded segments are located on both sides of the fixed block. The sag detector is sleeved on the first threaded segments. The first bracket is provided with a slide rail that is slidably connected to the sag detector.

[0014] The beneficial effects of the present invention: The present invention provides a positioning and guiding device for sheet piles. Two fixed blocks 1 are moved between the two layers of sheet pile cofferdam to be constructed. Based on the dimensions of the sheet piles, a second moving component 13 controls the movement of a support block, such that the distance between the support block and the fixed block 1 is the width of a single-layer sheet pile cofferdam, which is the width of two adjacent interlocking sheet piles. Based on the length of the sheet piles, a forward and backward moving component 15 controls the forward and backward movement of a clamping component 16, so that the clamping component 16 moves to one side of the concave inner wall of the sheet pile to be placed. Then, two [sheet piles] are placed on either side of the first connecting plate 8. Two sheet piles are placed symmetrically on the same side of the first connecting plate 8, with the convex outer walls of the two sheet piles abutting against the side walls of the first connecting plate 8 and the second connecting plate 27, respectively. The locking joints of the two symmetrical sheet piles cooperate with each other, and the inner wall of the sheet pile is pressed and positioned by the clamping member 16. The clamping member 16 and the side wall of the first connecting plate 8 or the side wall of the second connecting plate 27 facilitate the guidance and restriction of the sheet pile, which facilitates the vertical driving of the sheet pile into the ground. It can prevent the sheet pile from deviating when it is inserted into the foundation pit, and can position and guide multiple sheet piles, thus improving construction efficiency.

[0024] like Figures 1 to 5As shown, a positioning and guiding device for sheet piles includes two fixing blocks 1 connected by a first connecting plate 8. One fixing block 1 has a first bracket 10 perpendicular to the first connecting plate 8, and the other fixing block 1 has a second bracket 25 parallel to the first bracket 10. The first bracket 10 and the second bracket 25 are on the same horizontal plane. The second bracket 25 has two sliders 26 slidably connected about the fixing block 1. The first bracket 10 has a second moving member 13 connected to two support blocks 14 symmetrically arranged about the fixing block 1. The movable component 13 is used to control the two support blocks 14 to move towards or away from each other. The support block 14 is connected to a second connecting plate 27 parallel to the first connecting plate 8. The other end of the second connecting plate 27 is connected to the slider 26. Each second connecting plate 27 is provided with a front-to-back movable component 15. The first connecting plate 8 is provided with two front-to-back movable components 15. The front-to-back movable components 15 are connected to a clamping component 16. The front-to-back movable components 15 are used to control the clamping component 16 to move back and forth. The two clamping components 16 located on the first connecting plate 8 are oriented in opposite directions. The clamping component 16 is used to clamp the steel sheet pile placed between the first connecting plate 8 and the second connecting plate 27.

[0025] The two fixed blocks 1 are moved between the two layers of sheet pile cofferdam to be constructed. Based on the dimensions of the sheet piles, the second moving component 13 controls the movement of the support block 14, ensuring that the distance between the support block 14 and the fixed blocks 1 is equal to the width of the single-layer sheet pile cofferdam, which is the overall width of two adjacent interlocking sheet piles. Based on the length of the sheet piles, the forward and backward moving component 15 controls the forward and backward movement of the clamping component 16, moving it to one side of the concave inner wall of the sheet pile to be placed. Then, two sheet piles are placed on each side of the first connecting plate 8, located on the first connecting plate 8. Two sheet piles on the same side are placed symmetrically, and the convex outer walls of the two sheet piles abut against the side walls of the first connecting plate 8 and the second connecting plate 27, respectively. The locking joints of the two symmetrical sheet piles cooperate with each other. The clamping member 16 presses and positions the concave inner wall of the sheet pile. The clamping member 16 and the side wall of the first connecting plate 8 or the side wall of the second connecting plate 27 facilitate the guidance and restriction of the sheet pile, which facilitates the vertical driving of the sheet pile into the ground. It can prevent the sheet pile from deviating when it is inserted into the foundation pit. Multiple sheet piles can be positioned and guided, which improves the construction efficiency.

[0026] To facilitate the synchronous or opposite movement of the two support blocks 14 and to adjust the distance between the support blocks 14 and the fixed block 1 to accommodate sheet piles of different sizes, the second moving component 13 includes a second control component located on the first bracket 10. The second control component is connected to a second threaded rod and is used to control the rotation of the second threaded rod. The second control component can be a control motor or a rotating handle. The second threaded rod has two second threaded sections with opposite thread directions, located on both sides of the fixed block 1. The support blocks 14 are sleeved on the second threaded sections. The first bracket 10 is provided with a slide rail that is slidably connected to the support blocks 14. When the second control component controls the rotation of the second threaded rod, it drives the two support blocks 14 to move in opposite directions, thereby adjusting the distance between the support blocks 14 and the fixed block 1 to accommodate sheet piles of different sizes.

[0027] The second movable component 13 described above is replaceable. The second movable component 13 may include two second telescopic rods disposed on the first bracket 10. The two second telescopic rods are symmetrically arranged about the fixed block 1. The telescopic ends of the two second telescopic rods are respectively connected to the two support blocks 14. The extension and retraction of the two second telescopic rods are used to control the movement of the two support blocks 14.

[0028] To facilitate control of the back-and-forth movement of the clamping member 16, the back-and-forth moving member 15 can be a front-and-back telescopic rod. The telescopic ends of the front-and-back telescopic rod are connected to the clamping member 16. The extension and retraction of the front-and-back telescopic rod is used to control the back-and-forth movement of the clamping member 16, so as to move the clamping member 16 to one side of the concave inner wall of the corresponding sheet pile, which facilitates the subsequent restraint of the sheet pile by the clamping member 16.

[0029] Extension telescopic rods are provided between the first connecting plate 8 and the second bracket 25, and between the second connecting plate 27 and the second bracket 25. The extension telescopic rods can be extended to adjust the distance between the first bracket 10 and the second bracket 25, so as to adapt to steel sheet piles of different sizes in the length direction of the steel sheet pile.

[0030] The fixing block 1 has vertically penetrating anchor holes 5, and anchor piles 7 are installed in the anchor holes 5. The lower end face of the fixing block 1 has lower grooves 2 located on both sides of the anchor holes 5. A lifting cylinder 3 is installed in the lower grooves 2. The extension end of the lifting cylinder 3 is connected to a roller 4. The anchor piles 7 are driven into the ground through the anchor holes 5. The anchor holes 5 restrict the driving of the anchor piles 7 to prevent displacement. When it is necessary to control the fixing block 1 to move to other locations where anchor piles 7 need to be driven in, the lifting cylinder 3 extends and starts, extending the roller 4 out of the lower groove 2 to contact the ground. Then the lifting cylinder 3 continues to extend and lift the fixing block 1, causing the anchor piles 7 to disengage from the anchor holes 5. Then the fixing block 1 can be moved to other locations where anchor piles 7 need to be driven in. The lifting cylinder 3 retracts, and then the other anchor piles 7 are driven into the ground through the anchor holes 5, which facilitates fixing the positioning and guiding device to the ground and facilitates the subsequent driving of sheet piles.

[0031] Multiple first guide wheels 6 are provided on the side wall of the anchor hole 5 to facilitate the alignment and driving of the anchor pile 7 into the designated position, making it easier to drive the anchor pile 7 in smoothly.

[0032] like Figure 2 As shown, the clamping member 16 includes a base, on which a hollow sleeve 18 is connected. A moving rod 21, penetrating the sleeve 18, is connected to the base via a telescopic drive member 17. A connecting frame 20 is provided at the end of the sleeve 18 away from the base. Two symmetrically arranged sector gears 19 are rotatably connected to the connecting frame 20. The sector gears 19 are rotatably connected to the connecting frame 20 via a rotating shaft. Each of the two sector gears 19 is connected to a swing rod 23. The two swing rods 23 are symmetrically arranged about the moving rod 21. The outer wall of the moving rod 21 is provided with a groove for connecting the sector gears 19. The annular rack groove 22 is meshed with the gear 19. The end of the swing rod 23 away from the base and the end of the moving rod 21 away from the base are both provided with abutting guide wheels 24. The outer wall of the steel sheet pile abuts against the side wall of the first connecting plate 8 or the second connecting plate 27. The extension of the telescopic drive member 17 causes the moving rod 21 to extend and causes the two swing rods 23 to swing in opposite directions, so that the end of the moving rod 21 with the abutting guide wheel 24 abuts against the bottom wall of the inner wall of the steel sheet pile, and the end of the swing rod 23 with the abutting guide wheel 24 abuts against the inclined wall of the inner wall of the steel sheet pile, which is used to restrict the steel sheet pile.

[0033] The clamping member 16 is replaceable. The clamping member 16 may include a clamping telescopic rod. The telescopic end of the clamping telescopic rod is connected to a clamping plate. When the clamping telescopic rod extends, it causes the clamping plate to come into contact with and press against the inner wall of the steel sheet pile.

[0034] Multiple second guide wheels 9 are provided on the side walls of the first connecting plate 8 and the second connecting plate 27, which facilitates the guidance of the steel sheet pile after it has been positioned and restricted, so that the steel sheet pile can be driven into the ground more smoothly.

[0035] Both the first connecting plate 8 and the second connecting plate 27 are long vertical plates. The long vertical plates facilitate the vertical setting of the sheet pile when they abut against the side wall of the sheet pile, reducing the occurrence of displacement during the subsequent driving of the sheet pile.

[0036] The first support 10 is provided with a first movable component 11, which is connected to two sag detectors 12 symmetrically arranged about the fixed block 1. Each sag detector 12 is provided with a locking hook that cooperates with the locking jaw at the end of the sheet pile. The first movable component 11 is used to control the two sag detectors 12 to move towards or away from each other. The first movable component 11 controls the sag detectors 12 to move to the axial position where the locking jaws of the two cooperating sheet piles are engaged. The locking hooks cooperate with the locking jaws, which facilitates the engagement of the locking jaws at one end of the sheet pile and facilitates the positioning and restriction of the sheet pile.

[0037] The first moving part 11 includes a first control component located on the first bracket 10. The first control component is connected to a first threaded rod and is used to control the rotation of the first threaded rod. The first control component can be a control motor or a rotating handle. The first threaded rod is provided with two first threaded segments with opposite thread directions. The two first threaded segments are located on both sides of the fixed block 1. The sag detector 12 is sleeved on the first threaded segments. The first bracket 10 is provided with a slide rail that is slidably connected to the sag detector 12. When the first control component controls the rotation of the first threaded rod, it drives the two sag detectors 12 to move in opposite directions to adjust the distance between the sag detectors 12 and the fixed block 1 to adapt to steel sheet piles of different sizes. In addition, the sag detector 12 can perform sag detection.

[0038] The first movable component 11 described above is replaceable. The first movable component 11 may include two first telescopic rods disposed on the first bracket 10. The two first telescopic rods are symmetrically arranged about the fixed block 1. The telescopic ends of the two first telescopic rods are respectively connected to the two sag detectors 12. The telescopic extension and retraction of the two first telescopic rods are used to control the movement of the two sag detectors 12. The sag detectors 12 can be controlled to move to the axial position where the interlocking joints of the two steel sheet piles are engaged.
