[0025] As Figures 1-4 shown, the present utility model provides a technical solution: a metal pipe traction mechanism, including an upright column 1, a set of symmetric side columns 2 are fixedly connected to the bottom end of the upright column 1, a set of symmetric sliders 3 are movably connected to the outside of the side columns 2, mechanical claws 4 are fixedly connected to the bottom ends of the sliders 3, a distance adjustment mechanism 5 is arranged outside the upright column 1, and the bottom end of the distance adjustment mechanism 5 is movably connected to the top end of the slider 3, the bottom end of the upright column 1 is movably connected to a protection mechanism 6, both ends of the protection mechanism 6 are fixedly connected to the slider 3 respectively, and a set of symmetric limit strips 7 are fixedly connected to the bottom end of the protection mechanism 6.
[0026] First, install the column 1 at the bottom end of the lifting mechanism, control the movement of the column 1 through the lifting mechanism, and use the distance adjustment mechanism 5 to adjust the distance between the mechanical claws 4 according to the length of the metal pipe. At the same time, trigger the protection mechanism 6, and use the limit bar 7 to resist the top of the pipe to reduce the shaking of the pipe during movement.
[0027] like Figure 1 and Figure 2 As shown, the distance adjustment mechanism 5 includes a connecting rod 501, a movable block 502 and a screw 503, the column 1 passes through the movable block 502, and the column 1 is movably connected to the movable block 502, the screw 503 passes through the movable block 502, and the screw 503 is threadedly connected to the movable block 502, the connecting rod 501 is symmetrically arranged, the bottom ends of the connecting rods 501 are movably connected to the top ends of the sliders 3 through the rotating shafts, and the top ends of the connecting rods 501 are movably connected to the outside of the movable block 502 through the rotating shafts, the distance adjustment mechanism 5 also includes a servo motor 504, the servo motor 504 is fixedly connected to the inside of the column 1, the screw 503 is movably connected to the inside of the column 1 through the bearing, and the output end of the servo motor 504 is fixedly connected to the top end of the screw 503, the outer sides of the side columns 2 are movably connected with buffer blocks 8, the outer sides of the side columns 2 are sleeved with return springs 9, one end of the return spring 9 is fixedly connected to the end of the side column 2, and the other end of the return spring 9 is fixedly connected to the buffer block 8.
[0028] The column 1 is installed at the bottom end of the lifting mechanism, and the movement of the column 1 is controlled by the lifting mechanism. Then, the spacing of the mechanical claws 4 is adjusted according to the length of the metal pipe. By starting the servo motor 504, the screw 503 is driven to rotate inside the column 1. Since the screw 503 is threadedly connected with the movable block 502, the movable block 502 is controlled to move longitudinally along the column 1. Under the action of the connecting rod 501, the slider 3 is pushed to move along the side column 2. The distance between the mechanical claws 4 is adjusted, which helps to improve the stability of the movement of the pipe. In this way, the mechanical claws 4 are used to grab the pipe, and when the slider 3 moves to the end of the side column 2, the slider 3 contacts the buffer block 8, causing the return spring 9 to be compressed and shortened.
[0029] like Figure 1 , Figure 3 and Figure 4As shown, the protection mechanism 6 includes a compression spring 601, a buffer column 602, and a cross column 603. The compression spring 601 is fixedly connected to the inner bottom end of the column 1. The top end of the buffer column 602 is movably connected to the inner bottom end of the column 1, and the bottom end of the compression spring 601 is fixedly connected to the top end of the buffer column 602. The bottom end of the buffer column 602 is fixedly connected to the outer side of the cross column 603. The protection mechanism 6 further includes a buffer spring 604 and a moving block 605. The buffer spring 604 and the moving block 605 are both symmetrically arranged. The buffer spring 604 is fixedly connected to the inside of the cross column 603.

The towing rope 606 passes through the fixing blocks 607, and the towing rope 606 is movably connected to the fixing blocks 607.
[0030] When the slider 3 moves, it pulls the towing rope 606, causing the moving blocks 605 to move away from each other inside the cross column 603, so that the buffer spring 604 is compressed and shortened. When the mechanical gripper grips the pipe, the limiting strip 7 abuts against the top end of the pipe, causing the cross column 603 and the buffer column 602 to move upward, so that the compression spring 601 is shortened, thereby reducing the shaking of the pipe during movement.
[0031] Working principle: When in use, first, install the column 1 at the bottom end of the hoisting mechanism, control the movement of the column 1 through the hoisting mechanism, and then adjust the distance between the mechanical claws 4 according to the length of the metal pipe. By starting the servo motor 504, drive the screw rod 503 to rotate inside the column 1. Since the screw rod 503 is threadedly connected to the movable block 502, the movable block 502 is controlled to move longitudinally along the column 1. Under the action of the connecting rod 501, the slider 3 is pushed to move along the side column 2 to adjust the distance between the mechanical claws 4, so as to grab the pipe with the mechanical claws 4. When the slider 3 moves to the end of the side column 2, the slider 3 abuts against the buffer block 8, causing the return spring 9 to be compressed and shortened; when the slider 3 moves, it pulls the towing rope 606, causing the moving blocks 605 to move away from each other inside the cross column 603, so that the buffer spring 604 is compressed and shortened. When the mechanical gripper grips the pipe, the limiting strip 7 abuts against the top end of the pipe, causing the cross column 603 and the buffer column 602 to move upward, so that the compression spring 601 is shortened, thereby reducing the shaking of the pipe during movement.
