In addition, the abutment rod can be opened and abutted against the inside of the pipe pile near the end of the pipe pile, which can increase the friction when the plug-in part is pulled outward, prevent the plug-in part from detaching from the pipe pile, and improve stability.

[0017] 3. The end of the abutment rod abuts against the inner wall of the pipe pile through a rubber gasket. The rubber gasket can not only prevent the rigid contact between the abutment rod and the pipe pile from scratching the pipe pile, but also increase the friction between the abutment rod and the pipe pile to improve stability.

[0018] 4. When the second screw is rotated by turning the handle, under the limiting action of the telescopic limiting rod, the second screw can drive the pressing block downward to press against the outer wall of the pipe pile, thereby further pressing and fixing the pipe pile, significantly improving the connection stability between the hanger and the pipe pile.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-2 As shown, the utility model proposes a precast concrete pipe pile hoist, including a cable and two hangers, which are symmetrically installed at the ports on both sides of the pipe pile 1. The hanger includes an inverted L-shaped base plate 2 and a plug-in portion 3 inserted into the port of the pipe pile 1. A lifting ring is installed above the horizontal portion of the base plate 2, the end of the cable is fixedly connected to the lifting ring, and the middle portion of the cable is connected to the crane. The plug-in portion 3 includes an insertion rod 31, a first screw rod 32, a plurality of connecting rods 33 and an abutment rod 34. The insertion rod 31 is arranged below the horizontal portion of the base plate 2 and is vertically fixedly connected to the vertical portion of the base plate 2. The first screw rod 32 is coaxially installed in the middle cavity of the insertion rod 31, and is connected to a rotating drive member through the outside. The rotating drive member includes a hand wheel 322, which is installed on the end of the first screw rod 32 that extends outward through the vertical portion of the base plate 2, and the first screw rod 32 can be driven to rotate synchronously through the hand wheel 322.

[0023] A plurality of grooves 311 are evenly spaced on the outer wall of the plug rod 31. The end of the abutment rod 34 away from the vertical part of the base plate 2 is rotatably installed in the corresponding groove 311, and the other end abuts against the inner wall of the pipe pile 1. The movable opening 312 is provided at the bottom of the groove 311. When the abutment rod 34 is abutted and fixed with the pipe pile 1, it can be rotated and extended from the groove 311, and when it is not locked, it can be effectively retracted in the groove 311, thereby preventing the plug-in part 3 from plugging into the inner wall of the pipe pile 1, making it more convenient to use. In addition, the abutment rod 34 can be opened and abutted against the inside of the pipe pile 1 near the end of the pipe pile 1, which can increase the friction when the plug-in part 3 is pulled outward, prevent the plug-in part 3 from detaching from the pipe pile 1, and improve stability.

[0024] A moving block 321 is threadedly sleeved on the first screw rod 32, one end of the connecting rod 33 is rotatably connected to the moving block 321, and the other end passes through the movable opening 312 and is rotatably connected to the middle of the abutting rod 34. When the first screw rod 32 is driven to rotate by the hand wheel 322, the moving block 321 can be driven to slide left and right on the first screw rod 32, so that the abutting rod 34 is pushed outward through the connecting rod 33, so that the abutting rod 34 rotates outwardly toward the groove 311 with the rotating connection as the center until it abuts against the inner wall of the pipe pile 1, thereby realizing a stable fixed connection between the plug-in part 3 and the pipe pile 1, so that the device can be used to lift pipe piles 1 of different specifications.

[0025] The end of the abutment rod 34 abuts against the inner wall of the pipe pile 1 through a rubber gasket 341. The rubber gasket 341 can prevent the abutment rod 34 from rigidly contacting the pipe pile 1 and causing scratches on the pipe pile 1, and can also increase the friction between the abutment rod 34 and the pipe pile 1 to improve stability.

[0026] The horizontal part of the base plate 2 is vertically downwardly provided with a clamping piece that is pressed against the outer wall of the pipe pile 1. The clamping piece includes a second screw rod 41, a telescopic limit rod 43 and a pressure block 44. The second screw rod 41 is threaded vertically downward through the horizontal part of the base plate 2. The lower end of the second screw rod 41 is rotatably connected with the pressure block 44, and the pressure block 44 abuts against the outer wall of the pipe pile 1. The two ends of the telescopic limit rod 43 are respectively fixedly connected with the pressure block 44 and the horizontal part of the base plate 2, and a rotating handle 42 is installed at the upper end of the second screw rod 41. And a notch that matches the arc surface of the outer wall of the pipe pile 1 is provided below the pressure block 44, and the notch can effectively fit with the outer wall of the pipe pile 1, and the crimping is more firm. Among them, the telescopic limit rod 43 includes a sleeve 431 and a slide rod 432. The end of the sleeve 431 is fixedly connected below the horizontal part of the base plate 2, and the slide rod 432 is movably sleeved in the sleeve 431. The end of the slide rod 432 is fixedly connected with the pressure block 44. When the second screw 41 is rotated by turning the handle 42, under the limiting action of the telescopic limiting rod 43, the second screw 41 can drive the pressing block 44 to press downward on the outer wall of the pipe pile 1, thereby further pressing and fixing the pipe pile 1, significantly improving the connection stability between the hanger and the pipe pile 1.

[0027] When using the utility model, the plug-in parts 3 of the two hangers are inserted into the ports at both ends of the pipe pile 1, and the abutment rod 34 on the insertion rod 31 is effectively pressed and fixed against the inner wall of the pipe pile 1 by shaking the hand wheel 322, and then the second screw rod 41 is driven to extend downward by rotating the handle, and the pipe pile 1 is further pressed and fixed by the pressing block 44, which significantly improves the connection stability between the hanger and the pipe pile 1. After that, the crane can lift and move the pipe pile 1 through the cable connected between the two hangers.
