Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling mill technology, and in particular to an adjustable rolling mill hanger. Background Technology
[0002] A rolling mill roll is a pair of rolls rotating in opposite directions, with a slit or hole of a certain shape between them. A steel billet passes through the slit or hole and is rolled into steel. It is a tool that causes plastic deformation of metal and is an important consumable component that determines the efficiency of the rolling mill and the quality of the rolled product. There are many types of rolling mill rolls, the most common being cast steel rolls, cast iron rolls, and forged rolls.
[0003] Roll lifting devices are needed during the handling of rolls. A lifting device is a tool for clamping and moving rolls. However, traditional roll lifting devices have some problems in use. Although traditional roll lifting devices can lift rolls, different length roll lifting devices need to be changed when moving rolls of different lengths, which makes it more troublesome to move rolls. Therefore, an adjustable roll lifting device is needed to solve the above problems. Utility Model Content

[0008] Preferably, the outer side of the bidirectional threaded rod is provided with an external thread, and the inner side of the threaded sleeve is provided with an internal thread, forming a threaded connection between the bidirectional threaded rod and the threaded sleeve.
[0009] With the above structure, the threaded connection makes it more convenient to adjust the position of the connecting bracket during use.
[0010] Preferably, the threaded sleeves are provided in two sets, and the two sets of threaded sleeves are symmetrically distributed on the outside of the bidirectional threaded rod.
[0011] Preferably, the clamping structure includes a connecting block, a clamping seat, a cylinder, a fixing frame, a fixing seat, a slider, and a sliding groove. The sliding groove is formed inside the connecting frame, and a slider is installed inside the sliding groove. A fixing seat is fixed to one side of the slider. The cylinder is fixed to one side of the connecting frame, and a fixing frame is fixed at the connection between the cylinder and the connecting frame. One end of the cylinder is fixed to one side of the fixing seat. The bottom end of the slider is fixed to the connecting block, and a clamping seat is fixed to one side of the connecting block.
[0012] The above structure allows the rolls to be clamped during use, preventing them from moving erratically.
[0013] Preferably, the clamping seats are provided in two sets, and the two sets of clamping seats are symmetrically distributed at the bottom end of the connecting frame.
[0014] Preferably, the slider is inserted into the interior of the slide groove, and the slide groove and the slider form a sliding connection.
[0015] Compared with the prior art, the beneficial effects of this utility model are: when using this adjustable roll hanger, the position of the connecting frame can be adjusted according to the length of the roll by adjusting the structure, so that rolls of different lengths can be moved. Furthermore, the clamping structure can clamp the roll, so that the roll will not move randomly during the movement.
[0016] 1. With an adjustable structure, when the roll is moved, the worm and worm wheel work together to drive the double-threaded rod to rotate. As the double-threaded rod works with the threaded sleeve, the position of the connecting frame is adjusted so that it can clamp rolls of different lengths, thus completing the adjustment work.
[0017] 2. By setting up a clamping structure, during use, the connecting block is pushed to one side by the cylinder, thereby indirectly clamping the outer side of one end of the roll with the two sets of connecting blocks, making the roll more stable during the movement, thus completing the clamping work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model embodiment provides an adjustable roll hanger, such as Figures 1-5 As shown, it includes a lifting device body 1 and a hook sleeve 2; the top of the lifting device body 1 is welded with a hook sleeve 2, a mounting box 4 is installed on one side of the lifting device body 1, an adjustment structure 3 is provided inside the lifting device body 1, guide grooves 7 are opened on both sides inside the lifting device body 1, and guide blocks 8 are installed inside the guide grooves 7; the bottom end of the guide block 8 is fixed to the connecting frame 5, and a clamping structure 6 is provided inside the connecting frame 5.
[0026] In a further preferred embodiment of this utility model, such as Figures 1-5As shown: The adjustment structure 3 includes a handle 301, a worm gear 302, a worm wheel 303, a double-threaded rod 304, and a threaded sleeve 305. The double-threaded rod 304 is installed inside the lifting device body 1. The threaded sleeve 305 is installed on the outer side of the double-threaded rod 304. The bottom end of the threaded sleeve 305 is connected to the top end of the connecting frame 5. The worm wheel 303 is installed inside the mounting box 4 on one side of the double-threaded rod 304. The worm gear 302 is installed on one side of the worm wheel 303. The handle 301 is fixed to the top end of the worm gear 302. The outer side of the double-threaded rod 304 is provided with external threads, and the inner side of the threaded sleeve 305 is provided with internal threads. The double-threaded rod 304 and the threaded sleeve 305 form a threaded connection. There are two sets of threaded sleeves 305, and the two sets of threaded sleeves 305 are symmetrically distributed on the outer side of the double-threaded rod 304.
[0027] Specifically, when hoisting the rolls, the position of the connecting frame 5 is first adjusted according to the length of the rolls. During adjustment, the handle 301 is rotated, which drives the worm 302 to rotate. When the worm 302 rotates, it drives the bidirectional threaded rod 304 to rotate through the cooperation with the worm wheel 303. With the cooperation between the bidirectional threaded rod 304 and the threaded sleeve 305, the two sets of connecting frames 5 are adjusted in position, so that rolls of different lengths can be hoisted and the adjustment work is completed.
[0028] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The clamping structure 6 includes a connecting block 601, a clamping seat 602, a cylinder 603, a fixing frame 604, a fixing seat 605, a slider 606, and a sliding groove 607. The sliding groove 607 is opened inside the connecting frame 5, and the slider 606 is installed inside the sliding groove 607. The fixing seat 605 is fixed to one side of the slider 606. The cylinder 603 is fixed to one side of the connecting frame 5. The fixing frame 604 is fixed at the connection between the cylinder 603 and the connecting frame 5. One end of the cylinder 603 is fixed to one side of the fixing seat 605. The connecting block 601 is fixed to the bottom end of the slider 606. The clamping seat 602 is fixed to one side of the connecting block 601. Two sets of clamping seats 602 are provided. The two sets of clamping seats 602 are symmetrically distributed at the bottom end of the connecting frame 5. The slider 606 is inserted into the sliding groove 607, and a sliding connection is formed between the sliding groove 607 and the slider 606.
[0029] Specifically, after the position of the connecting frame 5 is adjusted, the cylinder 603 is started. After the cylinder 603 is started, it will push the slider 606 on one side of the fixed seat 605 to move inside the slide groove 607. When the slider 606 moves, it will drive the clamping seat 602 on one side of the bottom connecting block 601 to move. Thus, by using the two sets of clamping seats 602, the roll is clamped, so that the roll will not easily shake during the hoisting process, thereby completing the clamping work.
