Description

Technical Field

[0001] The utility model belongs to the technical field of pipe pile lifting, in particular to a pipe pile lifting device. Background Art

[0002] In the fields of construction engineering, infrastructure construction, port terminals, etc., pipe piles are important structural support materials. When using pipe piles, they need to be hoisted, and pipe pile hoisting equipment is needed.

[0003] At present, traditional pipe pile lifting equipment drives the lifting equipment to lift the hook, so that it can smoothly and accurately lift the hook to the same height as the pipe pile to be lifted, and then make the hook slowly and steadily approach the pipe pile until the central axes of the two roughly coincide to achieve precise docking, and then drive the hook to move relative to each other, so that it enters the interior of the pipe pile and forms a stable connection with it. However, in actual operation, there is a certain gap between the hook and the pipe pile, and the hook is not equipped with a fixing mechanism. Therefore, in the dynamic lifting process, especially when encountering external adverse factors such as wind changes or the inertia force of the lifting machinery itself, the relative shaking between the pipe pile and the hook becomes a problem that cannot be ignored. The occurrence of shaking not only aggravates the instability during the lifting process and increases safety risks, but may also cause scratches or damage to the surface of the pipe pile, affecting its service life and overall structural strength.

[0023] The pushing mechanism is arranged at the top of the connecting plate 1 6. The pushing mechanism includes a cylinder 7, which is fixedly connected to the top of the connecting plate 1 6. The output end of the cylinder 7 extends to the inside of the connecting plate 1 6 and is fixedly installed with a connecting shell 8. The bottom end of the connecting shell 8 is fixedly installed with a hook 20. The top of the inside of the connecting shell 8 is fixedly installed with a spring 9. The bottom end of the spring 9 is fixedly installed with a square plate 2 10. The bottom end of the square plate 2 10 is fixedly installed with a connecting plate 2 11. The connecting plate 2 11 extends downward to the inside of the hook 20 and is fixedly installed with a splint 12. The top of the inside of the connecting shell 8 is fixedly installed. A square shell 13 is installed on the side opposite to the spring 9, and a screw rod 14 is slidably connected to the inside of the square shell 13. The bottom end of the square shell 13 is rotatably connected to a limit ring 15 located on the surface of the screw rod 14. The bottom end of the limit ring 15 is fixedly installed with a gear 16 located on the surface of the screw rod 14. The screw rod 14, the limit ring 15 and the gear 16 are all threadedly connected. A motor 17 is fixedly installed on one side of the interior of the connecting shell 8, and a gear 2 18 meshing with the gear 16 is fixedly installed on the output end of the motor 17. The bottom end of the screw rod 14 is fixedly installed with a push block 19 located at the bottom end of the gear 16.

[0024] The above scheme is adopted: the operator drives the sliding plate 2 to move, and then the sliding plate 2 will drive the lifting equipment 3 and the fixed shell 4 to move, and then the fixed shell 4 will drive the moving plate 5 and the connecting plate 6 to move, and then the hook 20 will be at the same horizontal line with the pipe pile, and then the cylinder 7 can be driven, and then the output shaft of the cylinder 7 will push the connecting shell 8 and the hook 20 to drop or rise, and then align the bottom end of the hook 20 with the pipe pile, and then drive the moving plate 5 to move relative to each other, and then the moving plate 5 will pull the connecting plate 6 to move, and then the connecting plate 6 will drive the hook 20 to enter the interior of the pipe pile. At the same time that the bottom end of the hook 20 enters the interior of both ends of the pipe pile, the motor 17 can be driven to rotate gear 2 18, because gear 2 18 is engaged with gear 1 16, and then gear 2 18 will drive gear 1 16 to rotate, and while gear 16 rotates, gear 16 will drive The limiting ring 15 rotates, and since the limiting ring 15 and gear 16 are threadedly connected to the screw rod 14, when the limiting ring 15 and gear 16 rotate, the screw rod 14 will drop, and then the screw rod 14 will push the pushing block 19 to drop, and then the bottom end of the pushing block 19 will contact the top of the square plate 2 10, and then the pushing block 19 will push the square plate 2 10 to drop. When the square plate 2 10 moves, the spring 9 will be stretched, and then the square plate 2 10 will drive the connecting plate 2 11 and the splint 12 to drop, and then the bottom end of the splint 12 will contact the outer surface of the pipe pile, and the pipe pile can be clamped and fixed through the cooperation of the hook 20 and the splint 12. After the fixation is completed, the lifting equipment 3 can be driven, and then the lifting equipment 3 will drive the fixed shell 4, the movable plate 5 and the hook 20 to move, and at the same time, the sliding plate 2 can be driven to move, so that the pipe pile moves to the preset position.

[0025] like Figure 3 and Figure 5 As shown, slide grooves 21 are provided on both sides of the interior of the connecting shell 8, and pulleys 22 located inside the slide grooves 21 are rotatably connected on both sides of the connecting plate 2 11, and the surface of the pulley 22 fits with the inner wall of the slide groove 21. There are six hooks 20, and each group of three hooks 20 is located at both ends of the fixed shell 4, and the bottom ends of the hooks 20 close to the movable plate 5 are chamfered.

[0026] The above solution is adopted: through the design of the slide groove 21 and the pulley 22, when the connecting plate 21 moves, the pulley 22 will be driven to move. Since the surface of the pulley 22 fits the inner wall of the slide groove 21, the friction between the pulley 22 and the slide groove 21 will cause the pulley 22 to rotate, and then the connecting plate 21 and the splint 12 can be made to move more smoothly. Through the design of the hook 20, since the hooks 20 are grouped into three, the equipment can lift multiple pipe piles at one time, and the opposite side of the bottom end of the hook 20 is chamfered, which makes it easier for the hook 20 to be inserted into the interior of the pipe pile.

[0027] like Figure 2As shown, a protective shell 23 is fixedly installed on the top of the connecting plate 6, and a door panel 24 is provided on the opposite side of the protective shell 23. The protective shell 23 and the door panel 24 are hinged by a hinge chain 25. Heat dissipation holes 26 are opened on both sides of the surface of the protective shell 23, and the heat dissipation holes 26 are designed to be longitudinally symmetrical about the center of the protective shell 23.

[0028] The above-mentioned scheme is adopted: through the design of the protective shell 23, the door panel 24 and the hinge chain 25, since the door panel 24 is arranged on the surface of the cylinder 7, the cylinder 7 can be protected, and the protective shell 23 and the door panel 24 are hinged by the hinge chain 25, so that the door panel 24 can be rotated, and then the protective shell 23 can be opened, and then the operator can maintain the components inside the protective shell 23. Through the design of the heat dissipation hole 26, when the cylinder 7 is working, the air outside the equipment can enter the interior of the protective shell 23 from the heat dissipation hole 26, and then the cylinder 7 can be cooled. The heat dissipation hole 26 is symmetrically designed, which can increase the heat dissipation effect of the cylinder 7.

[0029] like Figure 2 and Figure 4 As shown, a fixing rod 27 is fixedly installed at the bottom end of the fixed shell 4, and the fixing rod 27 is designed to be symmetrical about the center of the fixed shell 4. A telescopic rod is provided inside the spring 9, and both ends of the telescopic rod are fixedly connected to the top of the square plate 2 10 and the top inside the connecting shell 8.

[0030] The above solution is adopted: through the design of the fixing rod 27, when the fixed shell 4 descends, the fixing rod 27 will also descend, and then the surface of the fixing rod 27 will contact the surface of the pipe pile, thereby fixing the pipe pile, avoiding the position of the pipe pile from shifting before the hook 20 enters the pipe pile. Through the design of the spring 9, since a telescopic rod is provided inside the spring 9, when the spring 9 is stretched, the telescopic rod will also shrink, and then the spring 9 can be limited to avoid deformation of the spring 9.

[0031] The working principle and use process of this utility model:

[0032] First, the operator drives the sliding plate 2 to move, and then the fixed shell 4 will drive the moving plate 5 and the connecting plate 1 6 to move, and the hook 20 will be in the same horizontal line with the pipe pile. Then the cylinder 7 can be driven so that its output shaft will push the connecting shell 8 and the hook 20 to drop or rise, and then align the bottom end of the hook 20 with the pipe pile, and then drive the moving plate 5 to move relative to each other, and then the hook 20 enters the interior of the pipe pile. At the same time as the bottom end of the hook 20 enters the interior of both ends of the pipe pile, the motor 17 can be driven to rotate the gear 2 18, and then the gear 2 18 will drive the gear 1 16 to rotate, and the gear 16 will Drive the limit ring 15 to rotate, and when the limit ring 15 and gear 1 16 rotate, the screw rod 14 will drop, and then the screw rod 14 will push the pushing block 19 to drop, and then the pushing block 19 will push the square plate 2 10 to drop. When the square plate 2 10 moves, the spring 9 will be stretched, and then the square plate 2 10 will drive the connecting plate 2 11 and the splint 12 to drop, and then the bottom end of the splint 12 will contact the outer surface of the pipe pile, and then the pipe pile can be clamped and fixed. After the fixation is completed, the sliding plate 2 and the lifting equipment 3 can be driven to move the pipe pile to the preset position, and finally the operation process is completed.
