Description

Technical Field

[0001] The utility model belongs to the technical field of roller hangers, in particular to a support roller hanger. Background Art

[0002] In the manufacturing process of large backup rollers, the quenching process is a key step, which directly affects the performance and service life of the backup rollers. Currently, the quenching process for large backup rollers generally adopts the vertical quenching method. This method requires the backup roller to be hoisted from a horizontal position to a vertical position for quenching. After quenching is completed, the backup roller is returned from the vertical position to the horizontal position. Therefore, the loading and unloading hoisting equipment has become an indispensable part of the quenching process.

[0003] The existing support roller sling usually adopts an integrally formed annular structure adapted to the end of the support roller. It is fastened and assembled on the support roller by multiple radial screws arranged circumferentially and cooperates with the sling of the lifting device to complete the lifting work. Although it can lift the support roller, there is a risk of screw cutting in the process of tightening multiple screws one by one, which may cause the sling to fall off and cause a safety accident. At the same time, since the screws need to be tightened or removed one by one to complete the installation and disassembly of the sling, the difficulty of loading and unloading is also high, and the labor intensity of the operator is high. Not only does it reduce production efficiency, but it also increases safety, equipment and quality risks during operation, and it is easy to cause the screws to be not tightened in place, affecting the stability and safety of the lifting process.

[0004] Therefore, there is a need for a support roller sling that is safe, efficient, easy to load and unload, and can ensure the stability of the lifting process. Utility Model Content

[0005] The purpose of the utility model is to provide a support roller hoist that is easy to load and unload, can effectively improve production efficiency, effectively reduce the labor intensity of operators and can achieve stable lifting, while also being able to improve safety during the lifting process over the support roller.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] A support roller sling includes a split clamping ring adapted to the end of the support roller; the split clamping ring includes two semicircular clamping rings symmetrically arranged and detachably connected, lifting ears radially symmetrically arranged on the outer ring walls of the two semicircular clamping rings and adapted to the lifting device, and bosses circumferentially arranged along the inner ring walls of the two semicircular clamping rings, wherein the bosses on the two semicircular clamping rings are adapted to the grooves circumferentially opened on the outer side wall of the end of the support roller.

[0008] A further improvement of the technical solution of the present invention is that the thickness of the boss decreases from the middle to both ends, and the end faces of both ends of the boss are inclined surfaces.

[0009] A further improvement of the technical solution of the present utility model is that the lifting ear is a cylindrical structure, one end of which is connected to the outer ring wall of the semicircular clamping ring, and the other end is provided with a circular protective plate, and the circular protective plate is provided with an anti-slip baffle.

[0010] A further improvement of the technical solution of the present utility model is that the anti-slip baffle is a long strip plate structure, which is detachably arranged on the circular protective plate, and the length of the anti-slip baffle is greater than the diameter of the circular protective plate.

[0011] A further improvement of the technical solution of the present invention is that when the two semicircular clamping rings are clamped on the ends of the support roller, the anti-slip baffles on the two circular protective plates are perpendicular to the length direction of the support roller.

[0012] A further improvement of the technical solution of the present invention is that the width of the anti-slip baffle decreases gradually along its length direction, a slot adapted for the anti-slip baffle is provided on the circular protective plate, and the width of the slot is smaller than the maximum width of the anti-slip baffle, and the anti-slip baffle can be inserted into the slot of the circular protective plate.

[0013] A further improvement of the technical solution of the present utility model is that: the lifting ear is arranged in the middle of the outer ring wall of the semicircular clamping ring, and the two ends of the semicircular clamping ring extend outward in the horizontal direction to form ears, and mounting holes are provided on the ears. When the two semicircular clamping rings are assembled on the end of the support roller, the ears at both ends are connected by a locking bolt passing through their mounting holes.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0015] The support roller lifting device of the utility model is convenient for loading and unloading, can effectively improve production efficiency, effectively reduce the labor intensity of operators and can achieve stable lifting, and at the same time can improve the safety during the lifting of the support roller. Due to the split structure, it is easier to maintain.

[0016] The utility model adopts a split-type clasp adapted to the end of the support roller; the split-type clasp includes two semicircular clasps arranged symmetrically and detachably connected, lifting ears radially symmetrically arranged on the outer ring walls of the two semicircular clasps and adapted to the lifting device, and bosses arranged circumferentially on the inner ring walls of the two semicircular clasps, wherein the bosses on the two semicircular clasps are adapted to the grooves circumferentially opened on the outer wall of the end of the support roller. The engagement of the bosses of the semicircular clasps with the grooves of the support roller ensures that the semicircular clasps are accurately engaged with the end of the support roller, avoiding unstable operation of the equipment due to improper installation position. The bosses of the semicircular clasps provide strong connection stability, reducing displacement of the support roller during lifting, effectively reducing the labor intensity of the operator and achieving stable lifting, while improving safety during the lifting of the support roller. The split design of the two semicircular clasps allows the semicircular clasps to be easily installed on the end of the support roller without complicated assembly process, and also facilitates future inspection and maintenance.

[0017] The thickness of the boss adopted in the present invention decreases gradually from the middle to the two ends, and the end faces of the boss are inclined surfaces, so that when the two semicircular clamping rings are combined, the two bosses can form an approximate elliptical shape, which is suitable for support rollers of different diameters. When the diameter of the support roller is small, the middle part of the boss of the two semicircular clamping rings can be relied on to provide clamping force for the support roller, that is, the short diameter of the approximate elliptical shape formed by the two bosses is used to clamp the support roller. When the diameter of the support roller is large, the two ends of the boss of the two semicircular clamping rings can be relied on to provide clamping force for the support roller, that is, the long diameter of the approximate elliptical shape formed by the two bosses is used to clamp the support roller.

[0018] The anti-slip baffle adopted by the utility model can effectively prevent the lifting rope of the lifting device from accidentally slipping off on the lifting lug, thereby increasing the safety of the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described in detail below with reference to the embodiments:

[0025] like Figure 1 As shown, the utility model provides a support roller sling, including a split clasp, and the split clasp is adapted to the end of the support roller 6. Specifically, the split clasp includes two semicircular clasps 1, which are symmetrically arranged and detachably connected. The outer ring walls of the two semicircular clasps 1 are radially symmetrically provided with lifting ears 2, which are adapted to the lifting device. At the same time, the two semicircular clasps 1 are respectively provided with bosses 3 along the circumference of their inner ring walls. The bosses 3 on the two semicircular clasps 1 are adapted to the grooves circumferentially opened on the outer wall of the end of the support roller 6. During assembly, the two split semicircular clasps 1 can be assembled to the end of the horizontally placed support roller 6, so that the bosses 3 on the two semicircular clasps 1 are engaged with the grooves circumferentially opened on the outer wall of the end of the support roller 6 and the two semicircular clasps 1 are connected. Then, the lifting ears 2 on the two semicircular clasps 1 are hung on two slings of the lifting device, so that the lifting device lifts the support roller into a vertical state. Among them, the semicircular clamping ring 1 can ensure that the semicircular clamping ring 1 is clamped in the accurate position of the end of the support roller 6 through the engagement of its boss 3 with the groove of the support roller 6, avoiding unstable equipment operation due to improper installation position, and the boss 3 of the semicircular clamping ring 1 can provide strong connection stability, reduce the displacement of the support roller 6 during the lifting process, effectively reduce the labor intensity of the operator and achieve stable lifting, and at the same time improve the safety during the lifting of the support roller 6, and the two semicircular clamping rings 1 adopt a split design, which can make the semicircular clamping ring 1 conveniently installed at the end of the support roller 6, without the need for a complicated assembly process, and also facilitate future inspection and maintenance.

[0026] In order to be suitable for support rollers 6 of different diameters, the thickness of the boss 3 decreases gradually from the middle to the two ends, and the end faces of the boss 3 are inclined surfaces, so that when the two semicircular retaining rings 1 are combined, the two bosses 3 can form an approximate elliptical shape, thereby being suitable for support rollers 6 of different diameters. That is, when the diameter of the support roller 6 is small, the middle part of the boss 3 of the two semicircular retaining rings 1 can be used to provide clamping force for the support roller 6, that is, the short diameter of the approximate ellipse formed by the two bosses 3 is used to clamp the support roller 6. When the diameter of the support roller 6 is large, the two ends of the boss 3 of the two semicircular retaining rings 1 can be used to provide clamping force for the support roller 6, that is, the long diameter of the approximate ellipse formed by the two bosses 3 is used to clamp the support roller 6.

[0027] In order to facilitate hoisting, the lifting ear 2 is a cylindrical structure, which is adapted to the lifting rope on the lifting device. One end of the lifting ear is connected to the outer ring wall of the semicircular clamping ring 1, and the other end is provided with a circular protective plate 2-1. Figure 2-Figure 4As shown, an anti-slip baffle 4 is provided on the circular protective plate 2-1. The design of the anti-slip baffle 4 can prevent the lifting rope of the lifting device from accidentally slipping on the lifting ear 2, thereby increasing the safety of the lifting process.

[0028] Among them, the anti-slip baffle 4 is a long strip-shaped plate-like structure, which is detachably arranged on the circular protective plate 2-1, and the length dimension of the anti-slip baffle 4 is greater than the diameter dimension of the circular protective plate 2-1. Preferably, when the two semicircular snap rings 1 are engaged with the ends of the support roller 6, the anti-slip baffles 4 on the circular protective plate 2-1 are perpendicular to the length direction of the support roller 6, thereby more effectively preventing the sling from accidentally slipping on the lifting lug 2 when lifting the support roller 6. Specifically, the width of the anti-slip baffle 4 decreases along its length direction, and a slot 2-2 adapted for the anti-slip baffle 4 is provided on the circular protective plate 2-1, and the width dimension of the slot 2-2 is less than the maximum width dimension of the anti-slip baffle 4. The anti-slip baffle 4 can be inserted into the slot 2-2 of the circular protective plate 2-1. Before lifting, put the lifting device's sling on the lifting ear 2 of the semicircular clamp 1, and then insert the anti-slip baffle 4 into the slot 2-2 of the lifting ear 2 to prevent the lifting device from accidentally slipping off the lifting ear 2 during lifting. After lifting is completed, pull out the anti-slip baffle 4 from the slot 2-2 of the lifting ear 2 and remove the lifting device's sling from the lifting ear 2, ensuring safe lifting and convenient operation.

[0029] To ensure balanced lifting, a lifting lug 2 is positioned in the middle of the outer ring wall of the semicircular snap ring 1. This helps maintain the balance of the support roller 6 during lifting, reducing rotation or swinging caused by a shift in the center of gravity, thereby improving the stability and safety of the lifting process. Each end of the semicircular snap ring 1 extends horizontally outward to form an ear, each with a mounting hole. When the two semicircular snap rings 1 are assembled on the ends of the support roller 6, the ears at both ends are connected by a locking bolt 5 extending through their mounting holes.
