[0001] The present application relates to the field of building construction, and in particular to a self-locking pile pulling device for a pipe pile. Background Art
[0002] In foundation engineering, prestressed pipe pile foundation is a widely used foundation form. In some construction sites, due to the presence of a large number of isolated rocks or concrete blocks, the pile position may shift when the first pile is hammered.

At this time, it is necessary to pull out the offset pile body to correct the pile position and ensure the construction quality.
[0003] However, in the traditional pile pulling process, the pile body is tied with steel wire ropes, and the prestressed pipe piles are pulled out of the soil under the action of the pulling force of the winch. When pulling the piles, the pile body is easy to slip under the restraint of the steel wire ropes, resulting in failure of pile pulling, affecting the construction progress, and there are problems such as low success rate of pile pulling and poor safety.

One end of the first connecting member 31 away from the sliding member 3 is hinged to the middle position of the second connecting member 41. One end of the second connecting member 41 away from the fixing member 4 is connected to an abutting member 5 for abutting against the inner wall of the pipe pile. The hinge point between the first connecting member 31 and the second connecting member 41 is located between the abutting member 5 and the fixing member 4. An acute triangle is formed between the first connecting member 31, the second connecting member 41 and the threaded rod 12.
[0034] When the pile is pulled out, one end of the wire rope 11 passes through the hole of the lifting ring 1 and is fixed to the lifting ring 1, the end of the wire rope 11 away from the lifting ring 1 is connected to the winch, and the adjusting member 2 is rotated to move the adjusting member 2 to the end of the threaded rod 12 close to the lifting ring 1, and the sliding member 3 is lifted to slide to the end of the threaded rod 12 close to the lifting ring 1, driving the end of the first connecting member 31 away from the sliding member 3 to rotate toward the direction close to the fixing member 4, the angle between the first connecting member 31 and the threaded rod 12 becomes smaller, and the first connecting member 31 is rotated to the direction close to the fixing member 4. The rotation of the connecting member 31 drives the second connecting member 41 to rotate toward the sliding member 3, the angle between the first connecting member 31 and the second connecting member 41 becomes larger, and the angle between the second connecting member 41 and the threaded rod 12 becomes smaller, so that the expansion range of the fastening member is contracted inward, the pile pulling device is inserted into the pile, the sliding member 3 is loosened, and the sliding member 3 slides toward the end of the threaded rod 12 close to the fixed member 4, driving the end of the first connecting member 31 away from the sliding member 3 to rotate toward the direction away from the fixed member 4, and the second connecting member 31 is rotated to the direction away from the fixed member 4.

When the adjusting member 2 abuts against the sliding member 3, the rotation continues. The adjusting member 2 and the abutting member 5 move and expand toward the inner wall of the pipe pile until they are pressed against the inner wall of the pipe pile. At this time, the adjusting member 2 and the sliding member 3 are pressed against each other, so that the pile pulling device is pressed against the pipe pile. The winch is started, and the winch drives the steel wire rope 11 to be wound up. The steel wire rope 11 pulls the pile pulling device to pull the pipe pile, thereby improving the stability of the connection between the pile pulling device and the pipe pile, making it less likely to loosen or fall off during pile pulling, thereby improving the success rate and safety of the pile pulling operation, and improving the efficiency and safety of the construction.
[0035] In order to improve the uniformity of the force on the pipe pile, the second connecting member 41 is arranged along the circumferential direction of the peripheral wall of the fixing member 4, and the abutting members 5 are distributed equidistantly along the circumferential direction of the peripheral wall of the threaded rod 12.
[0036] The peripheral wall of the sliding member 3 is fixedly connected with a first plate member 32, and the first plate member 32 is symmetrically arranged on both sides of the first connecting member 31. The first plate member 32 abuts against the first connecting member 31, and the first plate member 32 is provided with a first hinge assembly 33. The first hinge assembly 33 is inserted into the two first plate members 32, and the first connecting member 31 is rotatably connected with the first hinge assembly 33 to limit the rotation direction of the first connecting member 31, thereby reducing the possibility of unbalanced clamping force of the clamping member on the pipe pile due to directional deviation when the first connecting member 31 rotates, thereby improving the stability of the clamping of the clamping member 5 on the pipe pile.
[0037] The peripheral wall of the fixing member 4 is fixedly connected with a second plate member 42, and the second plate members 42 are symmetrically arranged on both sides of the second connecting member 41.

The second plate member 42 is provided with a second hinge assembly 43, and the second hinge assembly 43 is inserted into the two second plate members 42. The second connecting member 41 is rotatably connected with the second hinge assembly 43, and the rotation direction of the second connecting member 41 is limited, thereby further improving the stability of the abutment member 5 against the pipe pile.
[0038] Specifically, in this embodiment, the second connecting member 41 is composed of two steel plates, the first connecting member 31 is located between the two steel plates, and two ends of the steel plates are respectively fixed to the fixing member 4 and the abutting member 5 .
[0039] Reference Figure 2 and Figure 3 The inner wall of the second connecting member 41 is against the outer wall of the first connecting member 31, and the second connecting member 41 is inserted with the third hinge assembly 6. The third hinge assembly 6 is composed of a rod 61 and a locking member 62. The rod 61 is inserted into the first connecting member 31 and the second connecting member 41.

The structure of the first hinge assembly 33 and the structure of the first hinge assembly 33 are not described in detail here.
[0040] When adjusting the abutting member, the locking member 62 is loosened to make the first connecting member 31 and the second connecting member 41 in a relaxed state, which is convenient for adjusting the first connecting member 31 and the second connecting member 41 and improves the smoothness of adjustment. When the position of the abutting member is determined, the locking member 62 is tightened to fix the position of the first connecting member 31 and the second connecting member 41 and improve the efficiency and safety of pile pulling.
[0041] In order to improve the applicability of the self-locking pile pulling device for pipe piles and reduce the possibility of unstable tightness of the abutment member 5 due to limited expansion range, the fixing member 4 is provided with a threaded opening, the threaded rod 12 is inserted into the threaded opening, and the fixing member 4 is threadedly connected with the threaded rod 12.

[0043] The outer wall of the adjusting member 2 is fixedly connected with a rotating handle 8 , which is radially arranged on the outer wall of the adjusting member 2 . When the adjusting member 2 is rotated, the adjusting member 2 is rotated by holding the rotating handle 8 , thereby improving the convenience of rotating the adjusting member 2 .
[0044] An elastic gasket 9 is connected to the side of the abutment 5 away from the second connection member 41 . The elastic gasket 9 is fixed to the abutment 5 by rivets. The elastic gasket 9 is used to abut against the inner wall of the pipe pile. In this embodiment, the elastic gasket 9 is a rubber sheet.
[0045] When the pile pulling device is pressed against the inner wall of the pipe pile, the elastic gasket 9 is pressed against the inner wall of the pipe pile. The elastic gasket 9 can adapt to the shape of the clamping surface, improve the pressing stability, absorb the energy caused by external impact or vibration, reduce the influence of these factors on the clamping structure, and thus improve the overall stability.
[0046] The implementation principle of a self-locking pile pulling device for pipe piles in the embodiment of the present application is as follows: when pile pulling operation is required, the pile pulling device is inserted into the pipe pile, the fastening member expands outward, the elastic gasket 9 abuts against the inner wall of the pipe pile, the adjusting member 2 is rotated, the sliding member 3 moves toward the direction of the fixing member 4, the adjusting member 2 presses the position of the sliding member 3 in the pipe pile, the first connecting member 31 pushes the second connecting member 41 to rotate, so that the second connecting member 41 expands outward, and the elastic gasket 9 moves toward the inner wall of the pipe pile until it abuts against the inner wall of the pipe pile, so that the pile pulling device abuts against the pipe pile, and when the winch pulls the lifting ring 1 through the wire rope 11, the possibility of loosening or falling off of the wire rope 11 and the pipe pile during pile pulling, resulting in pile pulling failure or personal injury, is reduced, thereby improving the efficiency and safety of construction.
