Description

Technical Field

[0001] The invention relates to the field of cylinder support, in particular to an adjustable Pozidrivium support structure for a cylinder. Background Art

[0002] During the transportation of large cylinder structures, a support structure needs to be installed inside the cylinder. This support structure is a cross-shaped support structure. The traditional cross-shaped support of the cylinder is a simple steel pipe or steel section welded according to the inner diameter of the cylinder.

[0003] According to the different diameters of the cylinder, the corresponding welded Pozidrivium is made of different sizes. This Pozidrivium has two shortcomings: due to the large diameter of the cylinder section, the diameter of the Pozidrivium is also large, and the long legs of the existing Pozidrivium cannot be disassembled. There are problems with the transportation of large pieces during recycling, which often limits the recycling and reuse; the flange diameters of different projects are different, and the flange diameters of different cylinder sections in the same project are different. Since the length of the existing Pozidrivium cannot be adjusted, it is necessary to make a set of Pozidrivium for each project and each cylinder section, which leads to great waste. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides a 'Pozigzag' support structure which can be disassembled for easy transportation during recycling and can be adjusted in length to be applicable to cylinders of different diameters.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An adjustable Pozidriv support structure for a cylinder, comprising: a center plate, a connecting component and a switching component, a plurality of adjusting support pipes are arranged in the circumferential direction of the center plate, the adjusting support pipes comprising a fixed tube connected to the center plate, an extension tube with adjustable position connected inside the fixed tube, an arc-shaped abutment plate connected to the outer end of the extension tube; the connecting component is used to connect the fixed tube and the center plate, the connecting component comprises two limit plates fixed at the end of the fixed tube, the two limit plates are respectively in contact with the upper and lower surfaces of the center plate, the two side surfaces of the fixed tube are connected with connecting blocks abutting against the center side surfaces, the connecting blocks are provided with connecting holes, an elastic member for fixing the connecting block is connected to the center plate, the adjusting support pipe is disassembled through the connecting component, so as to facilitate transportation and reuse.

[0007] Preferably, an extension block extends from the side of the center plate, and the elastic member includes an elastic rod penetrating the extension block and inserted into the connecting hole, a spring is sleeved on the elastic rod, and two ends of the spring are respectively connected to the extension block and the elastic rod.

[0008] Preferably, the ends of the two elastic rods are connected with synchronization plates.

[0009] Preferably, a rotatably connected threaded rod is provided in the fixing tube, and the threaded rod is threadably connected to the extension tube.

[0010] Preferably, a rotating rod is provided on the fixed tube, and the rotating rod is connected to the end of the threaded rod through a bevel gear pair.

[0011] Preferably, the center plate is rotatably connected with gear one, a turning handle is fixed on the gear one, and a gear two meshing with gear one is fixed on the rotating rod.

[0012] Preferably, a switching member is provided on the limit plate, and the switching member includes a slider, and a sliding groove for the movement of the slider is opened on the limit plate, the slider is rotatably connected to the rotating rod, the top of the rotating rod is connected to a plate body, and an adjusting bolt is rotatably connected to the plate body, and a support block is fixed on the fixed tube, and the support block is threadedly connected to the adjusting bolt.

[0013] Preferably, the bevel gear pair includes two bevel gear bodies, one of which is fixedly connected to the rotating rod, and a synchronization rod is fixed on the other bevel gear body, and a synchronization bar is connected to the synchronization rod. A synchronization groove adapted to the synchronization rod and the synchronization bar is opened at the center of the threaded rod, and the synchronization rod and the threaded rod maintain synchronous rotation through the synchronization bar.

[0014] Preferably, a shielding plate is connected to the central plate, and a display slot is provided on the shielding plate, and the display slot can be used to observe whether gear one is meshing with gear two.

[0015] Preferably, guide plates are provided on both sides of the limiting plate, and the guide plates are fixed to the center plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The M-shaped support avoids the limitation of large-scale transportation during recycling and transportation. A M-shaped support structure is suitable for different projects and cylinder sections of different diameters. It is easy to operate and can be reused, which greatly reduces the production cost.

[0018] When the crisscross support structure is transported over a short distance, the extension tube can be received into the fixed tube by rotating the gear. At this time, the crisscross support structure occupies less space and is easy to move and carry. The connecting parts make the adjustable support tube detachable, which occupies less space and is convenient for long-distance transportation.

[0019] The position of the arc plate can be adjusted by rotating the threaded rod, and it also has the function of radial fine-tuning of the cylinder. During the placement of the cylinder, when micro-deformation occurs, the gear 2 at that position is meshed with the gear 1, and the remaining gears 2 are separated from the gear 1. At this time, rotating the gear 1 can adjust the radial support length of the micro-deformation position, thereby realizing the rounding function. The Pozigzag support structure can prevent the deformation (ovalization) of the cylinder for supporting large-diameter cylinders;

[0020] When installing the M-shaped support structure, the four adjustment support pipes can be removed first in the order of interval disassembly, so that the four adjustment support pipes and the arc-shaped abutment plate are maintained on the center plate. At this time, the structure is lighter and easier to move into the cylinder. The lighter structure makes it easier to take and maintain its longitudinal state. In conjunction with rotating gear one, multiple arc-shaped abutment plates can be moved together, so that the arc-shaped abutment plates can quickly abut against the inner wall of the cylinder. After the arc-shaped abutment plates abut against the inner wall of the cylinder, the four gears two and one are separated by rotating the adjusting bolt, and then the remaining adjustment support pipes are installed on the center plate. At this time, the adjusting bolt is rotated in the opposite direction, and the adjusting bolt moves in the opposite direction with the rotating mechanism connected thereto, so that gear two is meshed with gear one. Similarly, gear one is rotated so that the other half of the arc-shaped abutment plate abuts against the inner wall of the cylinder together. The operation is convenient and quick.

[0034] See also Figure 1-Figure 7, an adjustable Pozidriv support structure for a cylinder, comprising: a center plate 1, a connecting component 2 and a switching component 3. A plurality of adjustable support pipes 4 are arranged in the circumferential direction of the center plate 1. Eight adjustable support pipes 4 are arranged in the present application. The adjustable support pipes 4 include a fixed pipe 41 connected to the center plate 1, an extension pipe 42 with adjustable position is connected inside the fixed pipe 41, an arc-shaped abutment plate 43 is connected to the outer end of the extension pipe 42, and the diameter of the Pozidriv support structure can be adjusted by moving the extension pipe 42. The adjustable support pipe 4 is disassembled through the connecting component 2 for easy transportation and reuse.

[0035] The connecting component 2 is used to connect the fixed tube 41 and the center plate 1. The connecting component 2 includes two limit plates 21 fixed at the ends of the fixed tube 41. The limit plates 21 are distributed up and down. The two limit plates 21 are respectively in contact with the upper and lower surfaces of the center plate 1 to prevent the adjustment support pipe 4 from moving up and down. The two side surfaces of the fixed tube 41 are connected with connecting blocks 22 abutting against the central side surfaces. The connecting blocks 22 are provided with connecting holes. The center plate 1 is connected with an elastic member 23 for fixing the connecting block 22. The side surface of the center plate 1 is extended with an extension block 11. The elastic member 23 includes an elastic rod 231 that penetrates the extension block 11 and is inserted into the connecting hole. A spring 232 is sleeved on the elastic rod 231. The two ends of the spring 232 are respectively connected to the extension block 11 and the elastic rod 231. The ends of the two elastic rods 231 are connected with a synchronous plate 233. Guide plates 234 are provided on both sides of the limit plate 21. The guide plates 234 are fixed to the center plate 1. The two guide plates 234 limit the limit plate 21.

[0036] A rotatably connected threaded rod 5 is provided in the fixed tube 41, and the threaded rod 5 is threadedly connected to the extension tube 42. A rotating rod 6 is provided on the fixed tube 41, and the rotating rod 6 is connected to the end of the threaded rod 5 through a bevel gear pair 7. When the rotating rod 6 rotates, the threaded rod 5 is rotated through the bevel gear pair 7. The rotation of the threaded rod 5 causes the extension tube 42 to move, thereby causing the arc-shaped abutment plate 43 to abut against the inner wall of the cylinder.

[0037] A gear 18 is rotatably connected to the center plate 1, a turning handle is fixed on the gear 18, and a gear 29 meshing with the gear 18 is fixed on the rotating rod 6. By rotating the gear 18, all the gears 29 are rotated together, thereby moving all the extension tubes 42. The extension tubes 42 abut against the inner wall of the cylinder with the arc-shaped abutment plate 43. The arc-shaped abutment plate 43 moves together for easy and quick adjustment, and the adjustment distance is the same, which is conducive to accurately maintaining the shape of the cylinder. In addition, when the extension tubes 42 are received in the fixed tube 41 together, the cross-shaped support structure occupies little space and is convenient for movement and transportation.

[0038] A switching member 3 is provided on the limit plate 21, and the switching member 3 includes a slider 31. A sliding groove 32 for the slider 31 to move is opened on the limit plate 21. The slider 31 is rotatably connected to the rotating rod 6. The top end of the rotating rod 6 is connected to a plate body 33. The top end of the rotating rod 6 is rotatably connected to the plate body 33. An adjusting bolt 34 is rotatably connected to the plate body 33. A polygonal turning handle is fixed on the adjusting bolt 34 to facilitate the rotation of the adjusting bolt 34. A supporting block 35 is fixed on the fixing tube 41, and the supporting block 35 is threadedly connected to the adjusting bolt 34.

[0039] The bevel gear pair 7 includes two bevel gear bodies, one of which is fixedly connected to the rotating rod 6, and a synchronization rod 36 is fixed on the other bevel gear body, and a synchronization bar 37 is connected to the synchronization rod 36. A synchronization groove 38 adapted to the synchronization rod 36 and the synchronization bar 37 is opened at the center of the threaded rod 5. The synchronization bar enables the synchronization rod 36 to rotate synchronously with the threaded rod 5, and the synchronization rod 36 and the synchronization bar 37 are moved and inserted into the synchronization groove 38. A baffle plate 12 is connected to the center plate 1, and a display groove 121 is opened on the baffle plate 12. The display groove 121 can be used to observe whether gear 1 8 is meshing with gear 2 9.

[0040] When installing the adjusting support pipe 4, first press the synchronous plate 233 so that the upper end of the elastic rod 231 drops into the extension block 11, then place the limit plate 21 between the two guide plates 234, and then move toward the center line of the center plate 1. When the connecting block 22 contacts the side of the center plate 1, it stops. At this time, release the synchronous plate 233, and the elastic rod 231 is inserted into the connecting hole under the action of the spring 232, thereby fixing the adjusting support pipe 4. When disassembling, press the synchronous plate 233, and then move out the adjusting support pipe 4. The connection and disassembly are convenient and quick.

[0041] The center plate 1 has a hole in the center, and the two ends of the cylinder are connected by screws through the center hole to enhance the stability of the Pozi support in the longitudinal direction. The position of the arc plate can be adjusted by the threaded rod 5, which also has the function of fine-tuning the radial direction of the cylinder. During the placement of the cylinder, when a slight deformation occurs, the gear 2 9 at that position is meshed with the gear 1 8, and the other gears 2 9 are separated from the gear 1 8. At this time, rotating the gear 1 8 can adjust the slight deformation position.

[0042] The radial support length can realize the roundness correction function. The cross-shaped support structure can prevent the cylinder from deforming and becoming oval when supporting the large-diameter cylinder.

[0043] When installing the cross-shaped support structure, the four adjustable support pipes 4 can be removed first in the order of interval disassembly, so that the four adjustable support pipes 4 and the arc-shaped abutment plate 43 are maintained on the center plate 1. At this time, the weight is lighter, which is convenient for moving into the cylinder. The lighter structure makes it easier to take and maintain its longitudinal state. In combination with the rotating gear 8, multiple arc-shaped abutment plates 43 can be moved together, so that the arc-shaped abutment plates 43 can quickly abut against the inner wall of the cylinder, and the operation is convenient and quick. After the arc-shaped abutment plate 43 abuts against the inner wall of the cylinder, the adjusting bolt 34 is then rotated, the adjusting bolt 34 moves with the plate body 33, the plate body 33 moves with the rotating rod 6, the rotating rod 6 moves with the slider 31, the bevel gear pair 7, the gear 2 9, the synchronization rod 36 and the synchronization bar 37 move together, so that the gear 2 9 is separated from the gear 1 8, and the operation is performed in sequence, so that the four gears 2 9 are separated from the gear 1 8, and then the remaining adjustment support pipe fittings 4 are installed on the center plate 1, and the adjusting bolt 34 is rotated in the opposite direction at this time, and the adjusting bolt 34 moves in the opposite direction with the rotating mechanism connected thereto, so that the gear 2 9 is meshed with the gear 1 8, and the gear 1 8 is rotated in the same way, and the gear 1 8 causes the four newly meshed gears 2 9 to rotate, and the four gears 2 9 rotate to cause the other half of the arc-shaped abutment plate 43 to abut against the inner wall of the cylinder together.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be changed or modified without departing from the principles.
