DETAILED DESCRIPTION

[0035] like Figures 1 to 5 As shown, an embodiment of the utility model provides a clamp for quickly fixing and transferring high-temperature metal bars, including a clamping mechanism, which is divided into two groups. The two groups of clamping mechanisms are connected for relative rotation through a rotating shaft 2. The clamping mechanism includes two parallel hooks 1, a connecting shaft 3 rotatably connected between the two hooks 1, and a lifting ring 4 movably arranged at the center of the connecting shaft 3. The two hooks 1 on the same side of the two groups of clamping mechanisms are respectively provided with a relatively arranged moving rod 8 and a rotating rod 18, a connecting rod 7, a first end of which is rotatably connected to the rotating rod 18, and a second end of the connecting rod 7 is sleeved on the moving rod 8. A moving groove 10 for the moving rod 8 to move is penetrated on the connecting rod 7. A sleeve 9 is sleeved and slidably provided on the moving rod 8. A plurality of limit grooves 11 are relatively arranged along the length direction of the connecting rod 7, and a tightening device 6 for limiting the limit grooves 11 is provided on the sleeve 9.

[0036] Specifically, the hook of the lifting tool is directly hung on the lifting ring 4 through a hook chain, etc., and the hook claw 1 wraps the metal bar 5. In the process of driving the lifting ring 4 to move upward by the crane hook, the hook claw 1 automatically clamps the metal bar 5, and at the same time makes the moving rod 8 slide in the moving groove 10. After clamping, it is made to slide on the moving rod 8 through the sliding sleeve 9, and then the limiting groove 11 is limited by the tightening device 6 to fix the clamp as a whole, and finally it is transported to the tooling table / rack corresponding to the next process for deep processing of the next process. Compared with traditional handling methods such as locks and slings, this device does not require personnel to directly contact the high-temperature metal bars, thereby avoiding high-temperature injuries to personnel. At the same time, it automatically clamps during the lifting process, and personnel only need to fix and lock it. The operation is simple, which ensures the continuity between processes and improves the overall production efficiency. It solves the problem that the existing high-temperature metal bars are difficult to transport due to their physical properties at high temperatures, and are easy to cause injuries to personnel, thereby reducing the experience.

[0037] like Figures 3 to 5As shown, in the present embodiment, the movable rod 8 comprises an upper rod body 81 and a lower rod body 82, the lower rod body 82 is fixedly connected to the connecting rod 7, the upper rod body 81 is fixedly connected to the top of the lower rod body 82, the diameter of the upper rod body 81 is smaller than the diameter of the lower rod body 82, the sleeve 9 is sleeved on the upper rod body 81 and limited at the lower rod body 82, the height of the lower rod body 82 is lower than the height of the movable groove 10, a through hole 13 is penetrated by the sleeve 9, and sliders 17 are relatively fixedly connected to the sleeve 9 on both sides of the through hole 13, and a slide groove 12 is provided on the upper rod body 81 for the slider 17 to slide. Specifically, the setting of the slider 17 and the slide groove 12 can ensure the stability of the ring on the upper rod body 81, and at the same time improve the accuracy of the fastening device 6 in limiting the limiting groove 11.

[0038] like Figure 3 As shown, in this embodiment, the tightening device 6 includes a movable plate 63, which is movably arranged in the sleeve 9, and a movable groove 66 is provided in the sleeve 9 for the movable plate 63 to move. A movable block 62 is fixedly connected to the movable plate 63, and the movable block 62 is movably connected to the sleeve 9. A limiting plate 61 is movably arranged in the sleeve 9, and a movable groove 14 is provided in the sleeve 9 for the limiting plate 61 to move. The limiting plate 61 is fixedly connected to the side of the movable block 62 away from the movable plate 63, and the end of the limiting plate 61 away from the movable block 62 is fixedly connected to the limiting block 68, and the limiting block 68 is arranged relative to the limiting groove 11. A movable rod 64 is fixedly connected to the end of the movable plate 63 away from the movable block 62, and a spring 65 is sleeved on the movable rod 64. The spring 65 is located in the movable groove 14, and the pulling machine Structure 67, which is arranged on the sleeve 9 and is configured to pull the movable rod 64 to move, the pulling mechanism 67 includes a fixed plate 675, which is fixed on the sleeve 9, and a rotating plate 672, which is rotatably arranged on the fixed plate 675 through a rotating shaft 673, and the two ends of the rotating plate 672 are rotatably connected with a pull rod 671 and a driving rod 674 respectively, and the end of the driving rod 674 away from the rotating plate 672 is hinged to the end of the movable rod 64 away from the movable plate 63, and a connecting block 15 is fixedly connected between the movable block 62 and the limit plate 61, and the width of the connecting block 15 is smaller than the width of the limit plate 61, and a movable groove four 19 is provided on the sleeve 9 for the connection block 15 to move, and the movable groove four 19 is connected to the movable groove one 14, and a movable groove three 66 is provided on the sleeve 9 for the drive rod 674 and the movable rod 64 to move.

[0039] Specifically, when the limit groove 11 needs to be limited, the sleeve 9 is pressed down so that the limit block 68 squeezes the edge of the sleeve 9, thereby driving the movable plate 63 to squeeze the spring 65, and the limit block 68 slides into the movable groove 10. Since the limit block 68 is a wedge-shaped structure, the sleeve 9 can tighten the movable rod 8 and the connecting rod 7, thereby improving the stability of the clamping mechanism on the metal bar 5. When the sleeve 9 is to be released, the rotating plate 672 is pulled by the pull rod 671 to move, so that the rotating plate 672 drives the two driving rods 674 to move relative to each other, thereby driving the movable rod 64 to move, and the movable rod 64 drives the limit block 68 to disengage from the movable groove, at which time the sleeve 9 can be disassembled. It should be noted that when the limit block 68 does not limit the limit groove 11, the limit block 68 and the sleeve 9 are at the top of the connecting rod 7, and the limit block 68 will not slide into the movable groove 10 due to the movement of the movable rod 8. Only under the push of external force can the limit block 68 be pressed down into the movable groove 10.

[0040] Working principle:

[0041] The hook of the lifting tool is directly hung on the lifting ring 4 through a hook chain, etc., and the hook claw 1 wraps the metal bar 5. In the process of driving the lifting ring 4 to move upward by the crane hook, the hook claw 1 automatically clamps the metal bar 5, and at the same time makes the moving rod 8 slide in the moving groove 10. After clamping, it is made to slide on the moving rod 8 through the sliding sleeve 9, and then the limiting groove 11 is limited by the tightening device 6 to fix the clamp as a whole, and finally it is transported to the tooling table / rack corresponding to the next process for deep processing of the next process. Compared with traditional handling methods such as locks and slings, this device does not require personnel to directly contact the high-temperature metal bars, thereby avoiding high-temperature injuries to personnel. At the same time, it automatically clamps during the lifting process, and personnel only need to fix and lock it. The operation is simple, which ensures the continuity between the processes and improves the overall production efficiency. It solves the problem that the existing high-temperature metal bars are difficult to transport due to their physical properties at high temperatures, and are easy to cause injuries to personnel, thereby reducing the experience.
