Description

Technical Field

[0001] This utility model relates to the field of pipe pile shoe technology, specifically a static pressure pipe pile shoe. Background Technology

[0002] Pipe pile shoe is a steel plate component installed at the pile end during the construction of prestressed concrete pipe pile foundation. Its diameter is usually larger than that of the pipe pile. It is shaped like a "shoe" and wraps around the pile end. Its main functions are to protect the pile end, guide the pile driving, distribute the load, and prevent damage to the bearing layer. Pipe pile shoe is made of steel plate, which has high strength and durability and can withstand the impact and friction during the pile driving process.

[0003] However, existing pile shoes have poor pull-out resistance in actual use and often move up and down with the pipe pile when inserting or pulling it out, resulting in poor stability during use. To address this problem, a static pressure pipe pile shoe is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a static pressure pipe pile shoe to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a static pressure pipe pile shoe, comprising a pipe pile, with fixing components provided on both sides of the outer wall of the pipe pile, and frames provided on both the front and rear sides of the outer wall of the pipe pile. A driving component is provided in the inner cavity of each of the two frames, and a movable plate is provided on the side of each of the two driving components that is far apart from each other. Multiple fixing cones are provided on the side of each of the two movable plates that is far apart from each other, and multiple telescopic components are provided between the movable plate and the outer wall of the pipe pile.

[0005] Preferably, the fixing assembly includes a fixing cylinder, a screw, a clamping plate, and a guide rod. The fixing cylinder is fixedly inserted into the pipe pile, the screw is screwed into the inner cavity of the fixing cylinder, the clamping plate is rotatably connected to one end of the screw extending into the inner cavity of the pipe pile via a bearing, and the guide rod is slidably inserted into the pipe pile and fixedly connected to the clamping plate.

[0006] Preferably, the end of the screw located outside the pipe pile is provided with a handle.

[0007] Preferably, the drive assembly includes a lead screw, a knob, sliders, a fixed base, connecting rods, and a limiting assembly. One end of the lead screw is rotatably connected to the bottom of the inner cavity of the frame via a bearing, and the other end of the lead screw extends to the top of the frame and is fixedly connected to the knob. The two sliders are respectively screwed to the upper and lower sides of the outer wall of the lead screw. The fixed base is located on the side of the moving plate near the pipe pile. One end of each of the two connecting rods is hinged to the middle of the fixed base, and the other end of each connecting rod is respectively hinged to the two sliders. The limiting assembly is located on the outer wall of the pipe pile and is fixedly connected to the sliders.

[0008] Preferably, the limiting component includes a limiting groove and limiting blocks. The limiting groove is formed on one side of the outer wall of the pipe pile. The two limiting blocks are slidably embedded in the inner cavity of the limiting groove and are respectively fixedly connected to two sliders. The inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0009] Preferably, the threads on the upper and lower sides of the outer wall of the lead screw are arranged opposite to each other.

[0010] Preferably, the telescopic assembly includes a telescopic cylinder, a telescopic rod, a connecting groove, and a connecting block. The telescopic cylinder is disposed on one side of the outer wall of the pipe pile. The telescopic rod is slidably inserted into the inner cavity of the telescopic cylinder and fixedly connected to the moving plate. The connecting groove is formed on the inner wall of the telescopic cylinder. The connecting block is slidably embedded in the inner cavity of the connecting groove and fixedly connected to the outer wall of the telescopic rod. The inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Rotate the knob to drive the lead screw to rotate, which in turn generates a relative thread rotation force on the upper and lower threads on the outer wall of the lead screw. Under the limiting action of the limiting groove and the limiting block, the two sliders slide towards the middle of the lead screw at the same time. The two connecting rods push the fixed seat, the moving plate and the fixed cone to slide along a straight line towards the inner wall of the foundation pit under the limiting action of the telescopic rod and the telescopic cylinder. The fixed cone is inserted into the inner wall of the foundation pit, thereby fixing the pipe pile. This solves the problem that the existing pile shoe has poor pull-out resistance in actual use and often moves up and down with the pipe pile when inserting and pulling the pipe pile, resulting in poor stability during use. 2. Rotate the handle to make the screw rotate. Since the screw is screwed into the inner cavity of the fixed cylinder, when the screw rotates, the clamping plate can slide into the middle of the inner cavity of the pipe pile under the limiting action of the guide rod, thereby clamping the pipe pile with the two clamping plates. This allows the pipe pile to be clamped and fixed after it is inserted to the appropriate position. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4 This utility model provides a technical solution: a static pressure pipe pile shoe, including a pipe pile 1. Fixing components are provided on both sides of the outer wall of the pipe pile 1. A frame 2 is provided on both the front and rear sides of the outer wall of the pipe pile 1. A driving component is provided in the inner cavity of each of the two frames 2. A moving plate 3 is provided on the side of each of the two driving components that is far apart from each other. Multiple fixing cones 4 are provided on the side of each of the two moving plates 3 that is far apart from each other. Multiple telescopic components are provided between the moving plate 3 and the outer wall of the pipe pile 1. Through the driving components, the moving plate 3 and the fixing cones 4 can slide along a straight line towards the inner wall of the pit under the limiting action of the telescopic components, allowing the fixing cones 4 to insert into the inner wall of the pit, thereby fixing the pipe pile 1. This solves the problem that existing pile shoes have poor pull-out resistance in actual use, often moving up and down with the pipe pile 1 during insertion and extraction, resulting in poor stability during use. Through the fixing components, the pipe pile 1 can be clamped and fixed after it has been inserted to the appropriate position.

[0016] In this embodiment, the fixing assembly includes a fixing cylinder 5, a screw 6, a clamping plate 7, and a guide rod 8. The fixing cylinder 5 is fixedly inserted into the pipe pile 1, the screw 6 is screwed into the inner cavity of the fixing cylinder 5, the clamping plate 7 is rotatably connected to one end of the screw 6 extending into the inner cavity of the pipe pile 1 via a bearing, and the guide rod 8 is slidably inserted into the pipe pile 1 and fixedly connected to the clamping plate 7, so that the handle drives the screw 6 to rotate. Since the screw 6 is screwed into the inner cavity of the fixing cylinder 5, when the screw 6 rotates, the clamping plate 7 can slide towards the middle of the inner cavity of the pipe pile 1 under the limiting action of the guide rod 8, thereby clamping the pipe pile 1 with the two clamping plates 7, so that the pipe pile 1 can be clamped and fixed after it is inserted to the appropriate position.

[0017] In this embodiment, a handle is provided at one end of the screw 6 outside the pipe pile 1, and the screw 6 can be rotated by rotating the handle.

[0018] In this embodiment, the driving assembly includes a lead screw 9, a knob 10, sliders 11, a fixed base 12, connecting rods 13, and a limiting assembly. One end of the lead screw 9 is rotatably connected to the bottom of the inner cavity of the frame 2 via a bearing, and the other end of the lead screw 9 extends to the top of the frame 2 and is fixedly connected to the knob 10. Two sliders 11 are respectively screwed onto the upper and lower sides of the outer wall of the lead screw 9. The fixed base 12 is located on the side of the moving plate 3 near the pipe pile 1. One end of each of the two connecting rods 13 is hinged to the middle of the fixed base 12, and the other end of each connecting rod 13 is respectively hinged to the two sliders 11. The limiting assembly is located on the outer wall of the pipe pile 1 and is fixedly connected to the sliders 11, so that the knob 10... The rotating screw 9 generates a relative thread rotation force on the upper and lower threads on the outer wall of the screw 9. This causes the two sliders 11 to slide simultaneously toward the middle of the screw 9 under the limiting action of the limiting groove 14 and the limiting block 15. This causes the two connecting rods 13 to push the fixed seat 12, the moving plate 3, and the fixed cone 4 to slide along a straight line toward the inner wall of the pit under the limiting action of the telescopic rod 17 and the telescopic cylinder 16. This allows the fixed cone 4 to insert into the inner wall of the pit, thereby fixing the pipe pile 1. This solves the problem that the existing pile shoe has poor pull-out resistance in actual use and often moves up and down with the pipe pile 1 when inserting or pulling it out, resulting in poor stability during use.

[0019] In this embodiment, the limiting component includes a limiting groove 14 and limiting blocks 15. The limiting groove 14 is formed on one side of the outer wall of the pipe pile 1. Both limiting blocks 15 are slidably embedded in the inner cavity of the limiting groove 14 and are fixedly connected to two sliders 11 respectively. Under the joint action of the limiting groove 14 and the limiting blocks 15, the sliders 11 can be prevented from rotating with the lead screw 9 when the lead screw 9 rotates, which improves the stability of the drive component during use. The inner cavity of the limiting groove 14 and the outer wall of the limiting block 15 are adapted to each other and are both in the shape of "T", which can keep one end of the limiting block 15 embedded in the inner cavity of the limiting groove 14, which improves the stability of the limiting component during use.

[0020] In this embodiment, the threads on the upper and lower sides of the outer wall of the lead screw 9 are arranged opposite to each other, so that when the lead screw 9 rotates, the upper and lower sides of its outer wall generate relative thread rotational forces, causing the two sliders 11 to slide relative to each other simultaneously.

[0021] In this embodiment, the telescopic assembly includes a telescopic cylinder 16, a telescopic rod 17, a connecting groove 18, and a connecting block 19. The telescopic cylinder 16 is disposed on one side of the outer wall of the pipe pile 1. The telescopic rod 17 is slidably inserted into the inner cavity of the telescopic cylinder 16 and fixedly connected to the moving plate 3. The connecting groove 18 is opened in the inner wall of the telescopic cylinder 16. The connecting block 19 is slidably embedded in the inner cavity of the connecting groove 18 and fixedly connected to the outer wall of the telescopic rod 17. The inner cavity of the connecting groove 18 and the outer wall of the connecting block 19 are adapted to each other and are both dovetail-shaped. Under the combined action of the telescopic rod 17 and the telescopic cylinder 16, the moving plate 3 can always slide along a straight line. Under the combined action of the connecting block 19 and the connecting groove 18, one end of the telescopic rod 17 can always remain inserted into the inner cavity of the telescopic cylinder 16.
