[0024] A pipe hoisting device includes a horizontal frame 1, a hanging plate 2 is provided on the upper side of the horizontal frame 1, and the left and right sides of the bottom of the horizontal frame 1 are connected with clamping hooks 3 through rotating parts 4, and the two clamping hooks 3 are arranged opposite to each other, and a connecting rod 5 is connected between the two rotating parts 4, and the left end of the connecting rod 5 and the corresponding rotating part 4 are connected together by axial rotation, and the right end and the corresponding rotating part 4 are connected together by sliding along the length direction of the connecting rod 5. In this embodiment, in the initial state, the two clamping hooks 3 are arranged opposite to each other, that is, the hooks of the clamping hooks 3 are arranged perpendicular to the horizontal frame 1. When it is necessary to hoist the pipe, the device is lowered to the upper side of the pipe, and the two clamping hooks 3 are located at both sides of the pipe, and then the rotating part 4 at the left end is rotated. Under the action of the connecting rod 5, the rotating part 4 at the right end is rotated synchronously, that is, the two clamping hooks 3 are rotated from the opposite state to the opposite state, so that the hooks of the clamping hooks 3 are rotated to the inside of the pipe and hook the pipe.
[0025] The rotating member 4 includes a rotating shaft 401, a rotating block 402 and an inverted connecting block 403. Through holes are provided at the positions corresponding to the rotating member 4 on the horizontal frame 1. The rotating shaft 401 is arranged through the through holes, and the upper end of the rotating shaft 401 is fixedly connected to the rotating block 402 located on the upper side of the horizontal frame 1, and the lower end is fixedly connected to the connecting block 403. The connecting block 403 is fixedly connected to the upper part of the clamping hook 3 through a bolt and nut pair 9. In this embodiment, a first connecting hole is provided in the middle of the two side walls of the connecting block 403, and a second connecting hole is provided at the upper part of the clamping hook 3 corresponding to the connecting hole. The upper part of the clamping hook 3 is inserted between the two side walls of the connecting block 403, and is fixedly connected to the first connecting hole and the second connecting hole through the bolt and nut pair 9. In this embodiment, the rotating shaft 401, the rotating block 402 and the connecting block 403 are welded and fixed together. In this embodiment, the clamping hook 3 is fixedly connected to the connecting block 403 through the bolt and nut pair 9, which is also convenient for replacing the clamping hook 3 after bending and deformation in the later stage.
[0026] A rotating handle 404 is fixedly connected horizontally to the side wall of the rotating block 402, a U-shaped groove 501 is provided at one end of the connecting rod 5, and a strip hole 502 is provided horizontally at the other end, the rotating handle 404 of the rotating block 402 at the left end passes through the U-shaped groove 501, and is rotatably connected to the upper and lower side walls of the U-shaped groove 501 through a rotating shaft, and the rotating handle 404 of the rotating block 402 at the right end passes through the strip hole 502 and can move in the strip hole 502 along the length direction of the strip hole 502. In this embodiment, the upper and lower ends of the rotating shaft are interference-connected in the mounting holes on the upper and lower side walls of the U-shaped groove 501, and a through hole is provided on the rotating handle 404 at the left end corresponding to the rotating shaft, and the rotating shaft passes through the through hole and can rotate in the through hole.
[0027] The end of the rotating handle 404 of the left rotating member 4 is fixedly connected with an inverted L-shaped limit block 4041 upwards, and a steering column 6 is fixedly connected vertically on the upper side of the horizontal frame 1 at the left front of the rotating handle 404. A pull rope 7 is connected to the vertical section of the limit block 4041, and the other end of the pull rope 7 is freely set backwards around the front surface of the steering column 6. In this embodiment, when the clamping hook 3 needs to be rotated from the state where the hook part is perpendicular to the horizontal frame 1 to the state where the two hook parts are set facing each other, the operator can stand outside the pit and pull the pull rope 7 backwards to rotate the rotating member 4 at the left end to the left, and under the action of the connecting rod 5, the rotating member 4 at the right end rotates in the same direction, that is, the two clamping hooks 3 are rotated from opposite directions to opposite directions.
[0028] A torsion spring 8 is sleeved on the rotating shaft 401 of the right end rotating member 4, and a first stopper 4011 is fixedly connected to the rotating shaft 401 of the right end rotating member 4. A second stopper 101 is fixedly connected to the bottom of the horizontal frame 1. One end of the torsion spring 8 abuts against one side of the first stopper 4011, and the other end abuts against one side of the second stopper 101. In this embodiment, the pull rope 7 is pulled to drive the left end rotating member 4 to rotate to the left. Under the action of the connecting rod 5, the right end connecting member also rotates in the same direction, driving the two clamping hooks 3 to rotate to a state where the hooks are arranged facing each other. At this time, the torsion spring 8 is in a deformed and tightened state. When the pipeline is hoisted and needs to be removed, the pull rope 7 is released. Under the action of the torsion spring 8, the right end rotating member 4 rotates to the right to reset, and under the action of the connecting rod 5, the left end rotating member 4 rotates in the same direction, so that the two clamping hooks 3 are reset to a state where the hooks are perpendicular to the horizontal frame 1, that is, the hooks of the two clamping hooks 3 are removed from the pipeline. In this embodiment, the first stopper 4011 and the second stopper 101 are respectively located on the right side of the corresponding ends of the torsion spring 8 .
[0029] A rubber pad 301 is provided on the upper side of the hook of each clamp hook 3. When it is hung in the pipe, it not only plays an anti-slip role, but also can protect the edge of the inner wall of the pipe to prevent the edge of the inner wall of the pipe from being worn, especially for pipes with concrete structures, which can effectively prevent the edge of the inner wall from being chipped due to scratches.
[0030] The hanging plate 2 is welded to the middle of the upper side of the horizontal frame 1, and a hanging hole 201 is opened in the middle of the hanging plate 2 for hanging the hook of the lifting equipment.
[0031] The working process of this embodiment is as follows:
[0032] In the initial state, the two clamp hooks 3 are arranged opposite to each other, that is, the hooks of the clamp hooks 3 are arranged perpendicular to the horizontal frame 1. When it is necessary to hoist the pipeline, the hook of the lifting equipment is hooked in the hanging hole 201 on the hanging plate 2, and the device is lowered to the upper side of the pipeline, and the two clamp hooks 3 are located on both sides of the pipeline, and then the pull rope 7 is pulled backward to make the rotating part 4 at the left end rotate to the left, and under the action of the connecting rod 5, the rotating part 4 at the right end rotates in the same direction, that is, the two clamp hooks 3 are rotated from opposite directions to opposite directions, and finally the clamp hooks 3 are hooked on the inner wall of the pipeline. At this time, the pull rope 7 can be released, and the device is lifted by the lifting equipment to move the pipeline.
[0033] After being moved into position, the device is controlled to move downward by the lifting equipment, so that the hook parts of the two clamping hooks 3 are moved away from the inner wall of the pipeline. At this time, the torsion spring 8 is reset. Under the action of the torsion spring 8, the rotating member 4 at the right end rotates rightward to reset, and under the action of the connecting rod 5, the rotating member 4 at the left end rotates in the same direction accordingly, so that the two clamping hooks 3 are reset to a state where the hook parts are perpendicular to the cross frame 1, that is, the hook parts of the two clamping hooks 3 are moved out of the pipeline.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
