Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer wrapping pressure vessels, in particular to a layer wrapping pliers. Background Art

[0002] The multi-layer wrapped pressure vessel is formed by wrapping layers on the inner cylinder layer by layer. During production, the single layer of layer is first covered and fastened on the inner cylinder, and then the layer is welded. When covering and fastening the layer, it is necessary to first wrap the wire rope around the layer and cross it, and then put the two ends of the wire rope on the hook of the pre-tensioning mechanism, such as Figure 6 As shown, after tightening the layer plates with the steel wire rope, the splicing joints or the holes on both sides of the layer plates are clamped by the clamping mechanism. Since the outer rings of the layer plates are tightened all at once when the steel wire rope is tightened, there is a gap between the layer plates and the inner rings. Therefore, every time the steel wire rope is tightened, workers need to knock on the layer plates, and the tightening process is relatively cumbersome. Utility Model Content

[0049] See Figures 2 to 6This embodiment provides a layer board binding clamp, which is used to bundle the layer boards 10 and sleeve them on the outside of the inner tube 20. The layer boards 10 are symmetrically provided with splicing joints or matching holes on both sides. The layer board binding clamp includes a bracket 1, a pre-tightening mechanism 2, a first driving mechanism 3, a clamping mechanism 4 and a second driving mechanism 5.

[0050] The pre-tightening mechanism 2 includes two telescopic arms 21 , which are arranged on both sides of the layer board 10 . One end of the telescopic arm 21 is rotatably connected to the bracket 1 to form a rotating end 211 , and the other end forms a telescopic end 212 , on which a hook 213 is provided.

[0051] The first driving mechanism 3 is connected to the telescopic arm 21 and is used to drive the telescopic arm 21 to extend or swing.

[0052] The clamping mechanism 4 is connected to the bracket 1 and includes a clamp 41 and an abutment block 42 . The clamp 41 is used to clamp the spliced joint or the butt hole, and the abutment block 42 is used to abut the layer 10 or the inner tube 20 .

[0053] The second driving mechanism 5 is connected to the clamping mechanism 4 .

[0054] Among them, when it is necessary to tie the layer 10 to the inner cylinder 20, the steel wire can be first looped through the bottom of the layer and then hung on the corresponding hook 213. The first driving mechanism 3 can control the two telescopic arms 21 to shorten. At this time, the hook 213 pulls the steel wire rope. Since the abutment block 42 abuts against the layer 10 or the inner cylinder 20 (that is, the abutment block 42 abuts against the layer 10 or the top of the inner cylinder 20, and the steel wire rope surrounds the bottom of the layer 10), the steel wire rope is driven by the telescopic arm 21 to be tied upward, which will make the layer 10 close to the inner cylinder 20. When the steel wire rope is tied tightly to the lower part of the layer, the first driving mechanism 3 drives the two rotating ends 211 to swing in a direction close to each other, so that the two telescopic arms 21 are staggered with each other during the swing. Figure 4 At this time, the steel wire rope surrounds the entire layer 10, and the first driving mechanism 3 drives the telescopic arm 21 to extend. At this time, the two hooks 213 pull the steel wire rope to tighten the upper part of the layer 10. The second driving mechanism 5 controls the abutment block 42 to loosen the layer 10 or the inner tube 20, and makes the clamping clamp 41 clamp the splicing joints or holes on both sides of the layer 10.

[0055] The present embodiment provides a layer board binding clamp, which designs the pre-tightening mechanism 2 as two swingable telescopic arms 21, sets a hook 213 at the top of the telescopic arm 21, and connects an abutment block 42 to the clamping clamp 41 so that the abutment block 42 can abut the layer board 10 or the top of the inner tube 20, so that when the two telescopic arms 21 pull the wire rope, the lower part of the layer board 10 can be tightened first and then the upper part of the layer board 10 can be tightened, thereby reducing the gap between the layer board 10 and the inner tube 20, and eliminating the need for workers to constantly knock on the layer board during bundling, thereby solving the problems in the background technology.

[0056] Further, see Figure 3 The first driving mechanism 3 includes a first telescopic rod 31 and a second telescopic rod 32 .

[0057] The first telescopic rod 31 has two ends respectively connected to the rotating end 211 and the telescopic end 212. The first telescopic rod 31 is used to drive the telescopic arm 21 to extend and retract.

[0058] The two ends of the second telescopic rod 32 are respectively rotatably connected to the two rotating ends 211. The second telescopic rod 32 is used to drive the two telescopic arms 21 to swing.

[0059] For further information, please see Figure 3 The pre-tightening mechanism 2 further includes a linkage assembly 22 connected between the two rotating ends 211 to force the two rotating ends 211 to have the same angular velocity. Specifically, the linkage assembly 22 enables the two telescopic arms 21 to swing at the same angle.

[0060] Further, see Figure 5 The linkage assembly 22 includes a swing gear 221, a rack 222 and a central gear 223.

[0061] The swing gear 221 is connected to the rotating end 211 and can rotate coaxially with the rotating end 211 .

[0062] The rack 222 is slidably disposed on the bracket 1 and meshes with the swing gear 221 .

[0063] The two sides of the central gear 223 are respectively engaged with the two racks 222.

[0064] Among them, the neutral gear 223 is arranged in the middle of the bracket 1, and the rotating shaft is vertical. There are two groups of swing gears 221 and racks 222. The two groups of racks 222 are respectively engaged with the two sides of the neutral gear 223. The two swing gears 221 are respectively engaged with the two racks 222, and the two swing gears 221 are respectively connected to the two rotating ends 211. When the telescopic arm 21 swings, the gear rack structure makes the two telescopic arms 21 have the same swing angle.

[0065] Furthermore, the bottom of the rack 222 adjacent to the swing gear 221 is meshed with the swing gear 221, and the side of the rack 222 adjacent to the center gear 223 is meshed with the center gear 223. The rack 222 can be guided by providing a guide groove on the rack 222 and providing a guide rod on the bracket 1, and the guide groove is matched with the guide rod to achieve the guidance of the rack 222.

[0066] Further, see Figure 6 , in the examples provided in this embodiment:

[0067] The clamping pliers 41 include two clamping blocks, with a driving end 411 and a clamping end 412 formed at both ends of the clamping blocks respectively. A rotating portion 413 is formed between the driving end 411 and the clamping end 412 , and the two rotating portions 413 are rotatably connected.

[0068] The second driving mechanism 5 includes a third telescopic rod 51 and a fourth telescopic rod 52 . The third telescopic rod 51 is rotatably connected between the two driving ends 411 , and the fourth telescopic rod 52 is connected between the driving end 411 and the bracket 1 .

[0069] The clamping block can be a "T"-shaped structure, with the top two ends of the "T"-shaped structure forming a driving end 411 and a clamping end 412 respectively. The bottoms of the two "T"-shaped structures are rotatably connected. When the third telescopic rod 51 is extended or retracted, the two driving ends 411 move away from each other, and the two clamping ends 412 are driven toward each other, thereby clamping the spliced joints or holes on both sides of the layer 10. The fourth telescopic rod 52 can drive the clamping pliers 41 to move up and down as a whole. The abutment block 42 can be one side of the bottom of the clamping end 412, or it can be a metal block integrally connected to the clamping pliers 41. When the wire rope is tightened, the fourth telescopic rod 52 can be controlled to make the abutment block 42 abut against the layer 10 or the inner tube 20, thereby facilitating the wire rope to bundle the layer 10.

[0070] Furthermore, in the examples provided in this embodiment:

[0071] The abutment block 42 is connected to at least one clamping block. When the fourth telescopic rod 52 drives the clamping clamp 41 to move up and down, the abutment block 42 can be driven to abut or separate the layer plate 10 .

[0072] The clamping end 412 is rotatably connected to the rotating portion 413. When the clamping jaws 41 move downward and the abutment block 42 abuts the layer plate 10 or the inner cylinder 20, the clamping end 412 bends inward after contacting the layer plate 10, without affecting the abutment block 42. A return spring can be provided in the rotating portion of the clamping end 412. When the clamping jaws 41 move upward, the clamping end 412 returns to its original position, and when the rotating portion 413 rotates, the two clamping ends 412 can approach each other and clamp together.

[0073] Furthermore, the first telescopic rod 31 , the second telescopic rod 32 , the third telescopic rod 51 and the fourth telescopic rod 52 are hydraulic rods to increase torque.

[0074] Furthermore, there are multiple pre-tightening mechanisms 2 and clamping mechanisms 4 , and the multiple pre-tightening mechanisms 2 and clamping mechanisms 4 are staggered along the length direction of the bracket 1 .

[0075] Exemplarily, there may be three pre-tightening mechanisms 2 and two clamping mechanisms 4 , with one clamping mechanism 4 being provided between every two pre-tightening mechanisms 2 so as to fully clamp the layer plate 10 .

[0076] Working principle:

[0077] When it is necessary to tie the layer 10 to the inner cylinder 20, the steel wire can be first looped through the bottom of the layer and then hung on the corresponding hook 213. The first driving mechanism 3 can control the two telescopic arms 21 to shorten. At this time, the hook 213 pulls the steel wire rope. Since the abutment block 42 abuts against the layer 10 or the inner cylinder 20 (that is, the abutment block 42 abuts against the layer 10 or the top of the inner cylinder 20, and the steel wire rope surrounds the bottom of the layer 10), the steel wire rope is driven upward by the telescopic arm 21 to be tied tightly, which will make the layer 10 close to the inner cylinder 20. When the steel wire rope is tied tightly to the lower part of the layer, the first driving mechanism 3 drives the two rotating ends 211 to swing in the direction of approaching each other, and the two telescopic arms 21 are staggered during the swing. Figure 4 At this time, the steel wire rope surrounds the entire layer 10, and the first driving mechanism 3 drives the telescopic arm 21 to extend. At this time, the two hooks 213 pull the steel wire rope to tighten the upper part of the layer 10. The second driving mechanism 5 controls the abutment block 42 to loosen the layer 10 or the inner tube 20, and makes the clamping clamp 41 clamp the splicing joints or holes on both sides of the layer 10.
