Abstract
Description
Technical Field
[0001] The present application relates to the technical field of slings, and in particular to a hoisting device for rollers. Background Art
[0002] Currently, roller hoists mainly include several forms such as slings, chains or wire ropes. The common advantages of the above hoists are low requirements for the working environment, the hoisting force position can be changed at will, and the hoisting specifications range is wide.
[0003] However, when hoisting the roller, since there are no suitable hoisting positions at both ends of the roller, the lifting rope is very likely to slide relative to the roller during the hoisting operation, causing the roller to fall during the hoisting process, resulting in casualties or damage to equipment. Summary of the Invention
[0004] The purpose of this application is to provide a hoisting device for a roller, which is used to reduce the risk of falling off between the hoisting rope and the roller.
[0005] The present application provides a roller hoisting device that adopts the following technical solution:
[0006] A hoisting device for a rolling mill roller comprises a hoisting machine body. Both ends of the hoisting machine body are respectively provided with lifting ropes that can be raised and lowered. Anti-slip pads are provided between the lifting ropes and the rolling mill roller.
[0007] By adopting the above technical solution, when the rolling roller needs to be lifted, the crane is controlled to drive the lifting machine body to move to the rolling roller, and then the lifting machine body is controlled to drive the lifting rope to be sleeved on the end of the rolling roller. At this time, the anti-slip pad is located between the rolling roller and the lifting rope. When the lifting machine body drives the lifting rope to move upward, the lifting rope will drive the anti-slip pad to stick to the side wall of the rolling roller, thereby increasing the friction between the roller and the lifting rope, and reducing the risk of the rolling roller falling during the lifting process.
[0008] Optionally, a pressing component for pressing the anti-slip pad is provided between the sling and the anti-slip pad. A pressing component for pressing the anti-slip pad is provided between the sling and the anti-slip pad.
[0009] By adopting the above technical solution, the pressing component can increase the contact area between the anti-slip pad and the roller, and further improve the friction between the roller and the anti-slip pad.
[0010] Optionally, the pressing assembly includes a base plate with an arc-shaped longitudinal cross-section, and a plurality of compression springs arranged between the base plate and the anti-slip pad;
[0011] One end of the compression spring is fixedly connected to the base plate, the other end of the compression spring is movably connected to the anti-slip pad, and the base plate is fixedly connected to the hanging rope.
[0012] By adopting the above technical solution, when the lifting rope is lifting the roller, the anti-slip pad is placed on the lower side of the roller, and then the lifting rope is controlled to rise. At this time, the lifting rope drives the base plate to compress the compression spring. After the compression spring is compressed, it will squeeze the anti-slip pad, so that the anti-slip pad is tightly attached to the side wall of the roller.
[0013] Optionally, the compression spring is fixedly connected to a second connecting plate at one end close to the anti-slip pad, the second connecting plate is fixedly connected to a sphere at one side close to the anti-slip pad, and a groove for the sphere to be hinged is provided at a position corresponding to the sphere on the anti-slip pad.
[0014] By adopting the above technical solution, when the compression spring squeezes the anti-slip pad, the ball on the second connecting plate rotates in the groove of the anti-slip pad, which is conducive to the anti-slip pad better fitting on the side wall of the roller.
[0015] Optionally, a clamping assembly for pressing the end face of the roller is further provided on the base plate.
[0016] By adopting the above technical solution, when the roller is hoisted, the two end faces of the roller are clamped by the clamping assembly, thereby further improving the stability during the hoisting process.
[0017] Optionally, the clamping assembly includes a cylinder fixedly connected to the base plate, and the end of the cylinder is fixedly connected to the clamping plate.
[0018] By adopting the above technical solution, after the anti-slip pad is placed on the lower side of the roller, the control cylinder drives the clamping plate to abut against the end face of the roller, thereby clamping the two ends of the roller.
[0019] Optionally, a mounting block is fixedly connected to a side of the upper surface of the base plate away from the cylinder, and a guide rod fixedly connected to the clamping plate is provided through the mounting block.
[0020] By adopting the above technical solution, the stability of the clamping plate during movement is improved.
[0021] Optionally, a plurality of anti-slip bumps are provided on the upper surface of the anti-slip pad.
[0022] By adopting the above technical solution, the friction between the anti-slip pad and the roller is further increased.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When the roller needs to be hoisted, the crane is controlled to drive the hoisting machine body to move to the roller, and then the hoisting machine body is controlled to drive the lifting rope to be connected to the end of the roller. At this time, the anti-slip pad is located between the roller and the lifting rope. When the hoisting machine body drives the lifting rope to move upward, the lifting rope will drive the anti-slip pad to cling to the side wall of the roller, thereby increasing the friction between the roller and the lifting rope, reducing the risk of the roller falling during the lifting process;
[0025] 2. After placing the anti-slip pad under the roller, control the cylinder to drive the clamping plate to abut against the end face of the roller, thereby clamping both ends of the roller and further improving the stability of the roller during lifting;
[0026] 3. By providing anti-slip bumps on the upper surface of the anti-slip pad, the friction between the anti-slip pad and the roller can be further increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.
[0033] Example: A hoisting device for a roller, referring to Figure 1, including a crane body 1 installed on a traveling crane and a lifting rope 2 connected to the crane body 1. There are two lifting ropes 2, which are installed at both ends of the crane body 1 respectively. The lifting ropes 2 are used to lift the rollers. When the rollers need to be transported, the traveling crane is controlled to drive the crane body 1 to move to the position of the rollers, and then the lifting ropes 2 are driven down by controlling the crane body 1. The two lifting ropes 2 are respectively put on the two ends of the rollers, and then the crane body 1 is controlled to drive the lifting ropes 2 to rise. At this time, the lifting ropes 2 can lift the rollers, thereby transporting the rollers. In this embodiment, both ends of each lifting rope 2 are connected to the crane body 1, and the side of the lifting rope 2 away from the crane body 1 naturally droops to form a closed loop. The crane body 1 controls the two ends of the lifting rope 2 to rise and fall synchronously.
[0034] Reference Figure 1 and Figure 2 On the side of the lifting rope 2 that contacts the roller, an anti-slip pad 3 is provided. The anti-slip pad 3 is made of rubber and has an arc-shaped longitudinal cross-section. A clamping assembly 4 is also provided between the anti-slip pad 3 and the lifting rope 2. When the lifting rope 2 is lifting the roller, the lifting rope 2 uses the clamping assembly 4 to press the anti-slip pad 3 against the roller surface, which can increase the contact area between the anti-slip pad 3 and the roller, thereby increasing the friction between the anti-slip pad 3 and the roller, and thus reducing the risk of the lifting rope 2 falling off the roller.
[0035] Reference Figure 3 and Figure 4 The clamping assembly 4 includes a base plate 41 with an arc-shaped longitudinal cross-section and a plurality of compression springs 42 disposed between the base plate 41 and the anti-slip pad 3. The base plate 41 is fixedly connected to the inner side of the suspension rope 2. A first connecting plate 43 is fixedly connected to the side of each compression spring 42 near the base plate 41, and a second connecting plate 44 is fixedly connected to the side of each compression spring 42 near the anti-slip pad 3. The first connecting plate 43 is fixedly connected to the base plate 41 via bolts, and a ball 441 is fixedly connected to the side of the second connecting plate 44 near the anti-slip pad 3. A groove 31 is provided on the anti-slip pad 3 at a position corresponding to the ball 441. The ball 441 is inserted into the groove 31, forming a spherical hinge connection between the second connecting plate 44 and the anti-slip pad 3. When the roller is placed on the anti-slip pad 3, the anti-slip pad 3 deforms with the shape of the roller. At this time, the ball 441 on the second connecting plate 44 rotates within the groove 31 of the anti-slip pad 3, allowing relative movement between the second connecting plate 44 and the anti-slip pad 3. The ball hinge connection between the second connecting plate 44 and the anti-skid pad 3 enables the anti-skid pad 3 to fit the roller to the greatest extent, making the roller more stable during the lifting process.
[0036] A plurality of anti-skid bumps 32 are also provided on the surface of the anti-skid pad 3 in contact with the roller. The anti-skid bumps 32 can increase the friction between the anti-skid pad 3 and the roller, thereby reducing the possibility of relative movement between the roller and the anti-skid pad 3.
[0037] Reference Figure 3 A clamping assembly 5 is provided on the base plate 41 to clamp the ends of the rolls. The clamping assembly 5 includes a cylinder 51 fixedly mounted on the upper surface of the base plate 41. A clamping plate 52 is fixedly connected to the front end of the cylinder 51. The clamping plate 52 is located on the side of the anti-slip pad 3 away from the rolls. Two mounting blocks 6 are fixedly connected to the upper surface of the base plate 41 away from the cylinder 51. A guide rod 7 is provided through the two mounting blocks 6 and is fixedly connected to the clamping plate 52. The guide rod 7 is slidably connected to the two mounting blocks 6. A limit block 71 is fixedly connected to the end of the guide rod 7 away from the clamping plate 52. The longitudinal cross-section of the limit block 71 is larger than that of the guide rod 7. The provision of the limit block 71 prevents the guide rod 7 from disengaging from the mounting block 6. When the roll is placed on the anti-slip pad 3, the cylinder 51 is controlled to drive the clamping plate 52 to move to a position abutting the end face of the roll, thereby clamping the roll and further improving the roll's stability during the lifting process.
[0038] The implementation principle of the embodiment of the present application is: when lifting the rolling roller, start the crane to drive the lifting machine body 1 to move to the position of the rolling roller, and then place the anti-slip pad 3 on the lower side of the rolling roller. At this time, the base plate 41 and the compression spring 42 are both located on the lower side of the anti-slip pad 3; then control the cylinder 51 to drive the clamping plate 52 to abut against the end of the rolling roller. After ensuring that the clamping plate 52 is tightly against the rolling roller, control the lifting machine body 1 to drive the lifting rope 2 to rise. During the rising process of the lifting rope 2, the base plate 41 drives the compression spring 42 to squeeze the anti-slip pad 3. At this time, the compression spring 42 can drive the anti-slip pad 3 to completely fit on the side wall of the rolling roller. When the compression amount of the compression spring 42 reaches the maximum value, the lifting rope 2 can lift the rolling roller.
