Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a lifting device for rolling a large-diameter cylinder. Background Technology

[0002] Currently, when storing substances such as water, chemical raw materials, and oil, these substances have relatively low pressure requirements but require a large volume for storage. Typically, large storage tanks use thin-walled, large-diameter cylinders.

[0003] The equipment for rolling thin-walled large cylinders typically includes a lifting device and a plate rolling machine. During rolling, the lifting device is located above the plate rolling machine, which includes three rollers, with any one roller positioned above the other two and directly opposite the middle of the other two rollers. The lifting device supports and lifts the cylinder, which is positioned between the upper roller and the two lower rollers. As the rollers roll, they drive the cylinder to rotate along its own axis. The rollers and the lifting device work together to roll the cylinder into a standard shape. Traditional lifting devices typically use wire ropes or slings suspended from the top of the cylinder to lift it.

[0004] Regarding the aforementioned technologies, the contact area between the sling and the wire rope and the cylinder is relatively small, usually forming a straight line. As the roller rotates, the roller pulls on the cylinder, making it easy for deformation to occur at the contact point between the cylinder and the sling or wire rope, as well as in the surrounding area. This makes it difficult to roll the cylinder into the desired roundness, which is not conducive to improving the rolling effect of the device on the cylinder. Utility Model Content

[0005] To improve the rolling effect of the device, this application provides a lifting device for rolling large-diameter cylinders.

[0006] This application provides a lifting device for a rolled large-diameter cylinder, which adopts the following technical solution: A lifting device for rolling large-diameter cylinders includes two support rods and several connecting rods. The two support rods are arranged in parallel, and the connecting rods are located between the two support rods. The two ends of the connecting rods along the length direction are respectively connected to the two support rods. Several rollers for contacting the cylinder are provided on the support rods along the length direction. Support plates for supporting the rollers are provided on the support rods. The rollers are rotatably connected to the support plates. Limiting plates are provided at both ends of the support rods along the length direction. The limiting plates are connected to an external support device. The external support device suspends the device above the rolling machine, and the cylinder is located between the limiting plates on the same support rod.

[0007] By adopting the above technical solution, several connecting rods cooperate to connect and fix two support rods, improving the overall structural rigidity of the device. The support rods support the rollers through support plates, and the rollers cooperate with the winding plate to push the cylinder to roll, reducing the probability of wear caused by hard contact between the cylinder and the support rods. The limiting plate limits the displacement of the cylinder along the length of the support rods, reducing the probability of the cylinder shaking during the winding process. During the winding process, the external support equipment supports the cylinder through two support rods, dispersing the support force on the inner wall of the cylinder and reducing the stress at the supported position of the cylinder, thereby reducing the probability of deformation of the cylinder during the winding process and improving the winding effect of the device on the cylinder.

[0008] Optionally, the connecting rod includes an insertion plate and a receiving plate. One end of both the insertion plate and the receiving plate is fixedly connected to an adjacent support rod along the length direction. The receiving plate is hollow. The end of the insertion plate away from the support rod is inserted into the receiving plate and slidably connected to the inner wall of the receiving plate. The insertion plate is provided with fasteners for fixing the positions of the receiving plate and the insertion plate.

[0009] By adopting the above technical solution, the support rod supports and fixes the insertion plate and the receiving plate, and the receiving plate guides and limits the insertion plate. The operator can adjust the position of the insertion plate inserted into the receiving plate to adjust the distance between the two support rods to adapt to cylinders of different diameters, which helps to improve the applicability of the device.

[0010] Optionally, the support rod is provided with a fixing plate along its length. The fixing plate is perpendicular to the insertion plate. A double-acting screw is threaded between the fixing plates. A limit rod is slidably connected to the end of the fixing plate away from the double-acting screw. When the double-acting screw is rotated, the two fixing plates move closer or further away from each other along the limit rod. The two support rods move closer or further away from each other with the fixing plates. The insertion plate slides within the receiving plate with the fixing plates.

[0011] By adopting the above technical solution, the support rod supports and fixes the fixed plate, and the fixed plate supports and limits the bidirectional screw. When the operator rotates the bidirectional screw, the two fixed plates move closer or further apart along the bidirectional screw. The limiting rod guides and limits the two fixed plates, which makes it easier for the operator to adjust the relative position of the insertion plate and the receiving plate, and then adjust the position between the two support rods, which helps to improve the convenience of adjusting the distance between the support rods.

[0012] Optionally, the support rod has a guide groove along its length. The support plates on both sides of the same roller are fixedly connected to the same movable plate one on the side near the support rod. The movable plate one is located in the guide groove and moves along the length of the guide groove. The roller moves along the length of the guide groove with the movable plate one. The movable plate one is provided with a bolt one. The bottom of the wire groove has multiple threaded holes along its length. The bolt one passes through the movable plate one and is threadedly connected to the threaded holes.

[0013] By adopting the above technical solution, the guide groove guides and limits the displacement of the support plates along the length of the guide groove by the moving plate, thereby allowing the operator to adjust the position of the roller along the length of the guide groove. This facilitates the concentrated support of cylinders of different widths by the roller. The bottom of the guide groove is fixed with bolts through threaded holes, thereby fixing the moving plate and fixing the position of the roller through the support plate. This helps to improve the stability and applicability of the device.

[0014] Optionally, a fixing groove is provided at the bottom of the guide groove along the axial direction, and a moving rod is slidably connected in the fixing groove along the length direction. The moving rod is set perpendicular to the guide groove. A fixing component is provided on the moving rod for fixing the position of the moving rod. An elastic component is provided on the moving rod. One end of the elastic component is fixedly connected to the moving plate and the other end is fixedly connected to the fixing component. In its natural state, the elastic component has a tendency to push the moving plate away from the guide groove.

[0015] By adopting the above technical solution, the fixed groove guides and limits the displacement of the moving rod along the length of the support rod and the radial displacement along the support rod. The fixing member fixes the position of the moving rod along the length of the support rod. When the cylinder collides with the roller, the roller pushes the moving plate along the support rod, so that the moving plate pushes the moving rod along the support rod. The elastic member provides a buffer space for the moving rod, reducing the probability of the moving rod making hard contact with the inner wall of the fixed groove, thereby reducing the probability of damage to the cylinder caused by hard contact between the roller and the cylinder.

[0016] Optionally, the fixing component one includes a movable plate two and a bolt two. The movable plate two is sleeved on the lower end of the movable rod and is slidably connected with the guide groove. The bolt two passes through the movable plate two and is inserted into the threaded hole and threadedly connected to the threaded hole. The bolt head abuts against the movable plate two. One end of the movable rod that passes through the movable plate is connected to an abutment plate.

[0017] By adopting the above technical solution, the guide groove fixes the bolt two through the threaded hole, thereby fixing the moving plate two. This allows the moving plate two to limit the displacement of the moving rod along the length of the fixed groove. The moving plate also controls the radial displacement of the moving rod along the support rod through the abutment plate, reducing the probability of the moving rod detaching from the fixed groove.

[0018] Optionally, the limiting plate is slidably connected along the length of the support rod, and a fixing member 2 for fixing the position of the limiting plate is provided between the limiting plate and the support rod.

[0019] By adopting the above technical solution, the operator can change the distance between the two limiting plates on the same support rod by moving the position of the limiting plate, thereby limiting the cylinders of different widths. The second fixing component fixes the position of the limiting plate, which helps to improve the stability and applicability of the device.

[0020] Optionally, the second fixing component includes a locking sleeve, several annular grooves, and several bolts. The annular grooves are opened along the circumference of the support rod, and the several annular grooves are arranged along the length of the support rod. The locking sleeve is located in the annular groove, and the bolts pass through the limiting plate and are fixedly connected to the locking sleeve. The locking sleeve is made of deformable material and fits against the limiting groove in its natural state.

[0021] By adopting the above technical solution, when the operator tightens bolt three, the locking sleeve fits against the inner wall of the annular groove. The support rod fixes the locking sleeve through the annular groove, thereby fixing the locking sleeve to the limiting plate through bolt three. When the operator loosens bolt three, the locking sleeve deforms, causing it to disengage from the annular groove. The operator can then slide the limiting plate laterally along the support rod to adjust its position to accommodate cylinders of different widths, which improves the convenience of adjusting the position of the limiting plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Several connecting rods work together to connect and fix two support rods, improving the overall structural rigidity of the device. The support rods support the rollers through support plates. The rollers and the rolling plate work together to push the cylinder to roll, reducing the probability of wear caused by hard contact between the cylinder and the support rods. The limiting plate limits the displacement of the cylinder along the length of the support rods, reducing the probability of the cylinder shaking during the rolling process. During the rolling process, the external support equipment supports the cylinder through two support rods, dispersing the support force on the inner wall of the cylinder and reducing the stress at the support position of the cylinder, thereby reducing the probability of deformation of the cylinder during the rolling process and improving the rolling effect of the device on the cylinder. 2. The struts support and fix the insertion plate and the receiving plate, and the receiving plate guides and limits the insertion plate. The operator can adjust the position of the insertion plate inserted into the receiving plate to adjust the distance between the two struts to accommodate cylinders of different diameters, which helps to improve the applicability of the device. 3. The support rod supports and fixes the fixed plate, and the fixed plate supports and limits the double-acting screw. When the operator rotates the double-acting screw, the two fixed plates move closer or further apart along the double-acting screw. The limiting rod guides and limits the two fixed plates, which makes it easier for the operator to adjust the relative position of the insertion plate and the receiving plate, and then adjust the position between the two support rods, which helps to improve the convenience of adjusting the distance between the support rods.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses a lifting device for rolling a large-diameter cylinder.

[0030] Example 1 Reference Figure 1 A lifting device for rolling a large-diameter cylinder includes two support rods 1 and multiple connecting rods 2. The two support rods 1 are arranged in parallel, and the multiple connecting rods 2 are located between the two support rods 1. All connecting rods 2 are parallel to each other. The two ends of the connecting rods 2 along the length direction are welded and fixed to the two support rods 1 respectively. The two support rods 1 are connected by the connecting rods 2, which helps to improve the connection stability between the support rods 1.

[0031] Reference Figure 1 The support rod 1 has multiple support plates 51 welded along its length. Rollers 5 are rotatably connected between adjacent support plates 51. The support rod 1 supports the rollers 5 through the support plates 51, thereby enabling the rollers 5 to support the cylinder. During the rolling process, the cylinder rolls with the rollers 5, reducing the probability of friction damage to the cylinder caused by hard contact between the cylinder and the support rod 1, which is beneficial to improving the rolling effect of the cylinder.

[0032] Reference Figure 1Limiting plates 3 are welded to both ends of the support rod 1 along its length. A lifting ring passes through the upper end of each limiting plate 3. External support equipment lifts the limiting plates 3 via the lifting rings, thereby lifting the entire device to support the cylinder. During cylinder rolling, the cylinder is positioned between the two limiting plates 3 on the same support rod 1. The limiting plates 3 limit the displacement of the cylinder along the length of the support rod 1, reducing the probability of swaying during rolling and improving stability. During cylinder rolling, the two support rods 1 support different positions of the cylinder, reducing the supporting stress on the supported parts and lowering the probability of deformation or tearing at contact points due to excessive force per unit area, thus improving the rolling effect and safety.

[0033] The implementation principle of the lifting device for rolling a large-diameter cylinder according to an embodiment of this application is as follows: the external support equipment lifts the limiting plate 3 through the lifting ring, and then lifts the entire device to support the cylinder. The limiting plate 3 limits the displacement of the cylinder along the length direction of the support rod 1, reducing the probability of the cylinder swaying. The connecting rod 2 connects and fixes the two support rods 1, and improves the structural rigidity between the two support rods 1, so that the two support rods 1 support different positions of the cylinder, reducing the stress borne by the cylinder per unit area, thereby reducing the probability of the cylinder deforming or tearing and falling off due to excessive force per unit area during the rolling process, which is beneficial to improving the safety of the device during operation and the rolling effect of the cylinder.

[0034] Example 2 The difference between this embodiment and embodiment 1 is that a fixing plate 11 is welded inside the support rod 1, and the fixing plate 11 is arranged along the length direction of the support rod 1.

[0035] Reference Figure 2 The connecting rod 2 includes a receiving plate 21 and an insertion plate 22. One end of the receiving plate 21 and the insertion plate 22 along their length is fixedly welded to two support rods 1, respectively. The end of the insertion plate 22 away from the support rod 1 is inserted into the receiving plate 21 and slides along the length of the receiving plate 21. The receiving plate 21 supports and guides the movement of the insertion plate 22. A through hole is provided at the upper end of the receiving plate 21 along its length. The insertion plate 22 is provided with a fastener 23, which can be a screw. The screw passes through the through hole and the insertion plate 22 in sequence and is threadedly connected to the insertion plate 22. The receiving plate 21 is fixed to the insertion plate 22 by the screw, thereby fixing the position of the insertion plate 22 in the receiving plate 21. This allows the operator to adjust the distance between the two support rods 1 to accommodate cylinders of different diameters, which helps improve the applicability of the device.

[0036] Reference Figure 2Two fixed plates 11 are threaded to one end along their length with the same bidirectional lead screw 12, and the end of the fixed plate 11 away from the bidirectional lead screw 12 is slidably connected to the same limiting rod 13. After the operator loosens and removes the fastener 23, the bidirectional lead screw 12 is rotated to move the fixed plate 11 along the length of the limiting rod 13. The limiting rod 13 limits and guides the movement of the fixed plate 11, thereby causing the fixed plate 11 to drive the two support rods 1 to move closer or further away from each other along the length of the limiting rod 13, thus adjusting the distance between the two support rods 1, which helps to improve the convenience of position adjustment between the support rods 1.

[0037] Reference Figure 2 and Figure 3 The support rod 1 has a guide groove 14 along its length. A movable plate 52 is welded to the side of the support plates 51 on both sides of the same roller 5, near the axis of the support rod 1. The movable plate 52 is located within the guide groove 14 and is slidably connected to the bottom of the guide groove 14 along its length. The guide groove 14 guides and limits the movement of the movable plate 52, thereby guiding and limiting the movement of the support plate 51. The support plate 51 drives the roller 5 to move along the length of the guide groove 14, allowing the roller 5 to provide concentrated support for cylinders of different widths to accommodate them. Bolts 53 are installed on the movable plate 52. Multiple threaded holes 16 are formed along the length of the guide groove 14. The bolts 53 pass through the movable plate 52 and the threaded holes 16 in sequence and are threadedly connected to the threaded holes 16. The threaded holes 16 are fixed to the movable plate 52 by the bolts 53, thereby fixing the position of the support plate 51 and ultimately fixing the position of the roller 5, which helps improve the stability of the roller 5 during rolling.

[0038] Reference Figure 2 and Figure 4 The limiting plate 3 is slidably connected to the support rod 1 along its length. A fixing component 4 is installed on the support rod 1. The fixing component 4 includes a locking sleeve 41, multiple limiting grooves 43, and multiple bolts 42. The limiting grooves 43 are all formed on the support plate 51. The locking sleeve 41 is located within the limiting groove 43. The bolts 42 pass through the limiting plate 3 and are rotatably connected to the locking sleeve 41. The locking sleeve 41 is made of a deformable material, which can be metal. The operator tightens the bolts 42 to make the locking sleeve 41 fit against the inner wall of the annular groove. The inner wall of the annular groove, through the locking sleeve 41 and the bolts 42, fixes the displacement of the limiting plate 3 along the length of the support rod 1. A rubber pad is fitted on the bolts 42. When the bolts 42 are tightened, the rubber pad abuts against the limiting plate 3, thereby increasing the friction between the bolts 42 and the limiting plate 3, improving the installation stability of the bolts 42, and thus improving the overall installation stability of the limiting plate 3.

[0039] Reference Figure 2 and Figure 4When the operator loosens bolt 3 42, bolt 3 42 moves the locking sleeve 41 closer to the limiting plate 3, causing the locking sleeve 41 to deform and disengage from the limiting groove 43. This allows the operator to change the position of the limiting plate 3 along the length of the support rod 1, thereby changing the position between the two limiting plates 3 on the same support rod 1. This limits the width of the cylinder, reducing the probability of the cylinder shaking during the rolling process and improving the applicability of the device.

[0040] Example 3 The difference between this embodiment and embodiment 2 is that a fixing groove 15 is provided at the bottom of the guide groove 14 along the length direction.

[0041] Reference Figure 5 A movable rod 55 is slidably connected within the fixed groove 15 along its own length. The fixed groove 15 limits the displacement of the movable rod 55 along its length and its radial displacement along the support rod 1. A fixing component 6 is provided on the movable rod 55, comprising a movable plate 61 and a bolt 62. The movable plate 61 is sleeved on the outside of the movable rod 55 and slidably connected to the inner wall of the guide groove 14. The guide groove 14 guides and positions the displacement of the movable plate 61. The bolt 62 passes through the movable plate 61 and the threaded hole 16 and is threadedly connected to the threaded hole 16. The guide groove 14 is fixed to the movable plate 61 by the bolt 62, thereby fixing the movable rod 55 along its position within the guide groove 14. One end of the movable rod 55 passing through the movable plate 61 is connected to an abutment plate 56, reducing the probability of the movable rod 55 detaching from the fixed groove 15 and improving the installation stability of the movable rod 55.

[0042] Reference Figure 5 An elastic element 54, which can be a spring, is installed between the first movable plate 52 and the second movable plate 61. The spring is sleeved on the outside of the movable rod 55. One end of the spring along its length is fixedly connected to the first movable plate 52, and the other end is connected to the second movable plate 61. The spring contracts or expands along the movable rod 55, and the movable rod 55 guides and limits the spring. When the cylinder collides with the roller 5, the roller 5 drives the support plate 51 to move towards the guide groove 14. The support plate 51 drives the movable rod 55 to slide into the guide groove 14 through the first movable plate 52. The spring provides a buffer space for the movement of the movable rod 55, reducing the probability of the movable rod 55 being damaged due to hard contact with the bottom of the fixed groove 15. This, in turn, reduces the probability of the roller 5 being damaged by friction on the inner wall of the cylinder due to hard contact with the cylinder, which is beneficial to improving the stability of the device and the rolling effect of the cylinder.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
