Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology, and in particular to a vibration reduction device. Background Technology

[0002] Steam pipelines are a type of thermal pipeline, suitable for insulation projects of various cold and hot water pipelines at high and low temperatures. Steam pipelines possess excellent mechanical and thermal insulation properties, typically withstanding temperatures up to 120℃. Through modification or combination with other insulation materials, they can withstand temperatures up to 180℃. When steam flows within the pipeline, changes in steam pressure and flow velocity, as well as the pipeline's layout, can cause vibrations. Prolonged vibration can lead to weld cracking, flange loosening, and even pipeline rupture. Using vibration dampers can effectively absorb and reduce vibration energy, minimizing damage to the pipeline system and extending its service life.

[0003] However, during the disassembly and assembly of pipeline vibration dampers, various tools are often required for bolting or welding, especially for the disassembly and assembly of the suspension hooks and frames, which is quite cumbersome. Therefore, there is an urgent need for a pipeline vibration damper that can be quickly disassembled and assembled without tools. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0024] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0025] To achieve tool-free, quick assembly and disassembly of shock absorbers, this utility model proposes a shock absorber that can be used as a shock absorber for pipelines or other lifting components, such as... Figure 1 As shown, the shock absorber structure of this utility model includes:

[0026] The connecting frame 100 includes at least a top structure 110 and a bottom structure 120 disposed opposite to each other, and a frame body 130 for connecting the bottom structure and the top structure; the damping structure 200 includes a damping body 210 and a connecting rod 220, the damping body 210 is disposed inside the connecting frame 130 and elastically abuts against the bottom structure 120 of the connecting frame 100, the connecting rod 220 passes through the damping body 210 and one end is connected to the non-abutting end of the damping body 210, and the other end protrudes from the bottom structure 120 for connecting a pipe fixing device; the suspension structure 300 is installed on the top of the connecting frame 100 and is detachably plugged into the top structure 110.

[0027] In this embodiment, the shock absorber consists of three parts, with a relatively simple structure. It can be assembled by abutting the shock-absorbing structure 200 with the connecting frame 100 and by inserting the suspension structure 300 with the connecting frame 100. The assembly process is simple and does not require tools, which greatly improves the efficiency of the shock absorber's assembly and disassembly.

[0028] In an optional embodiment, the connecting frame 100 includes a frame body 130 pre-welded with angle steel, the frame body 130 having a rectangular hexahedral structure, and pre-treated steel plates welded to the top and bottom of the rectangular hexahedron to form the aforementioned top structure 110 and bottom structure 120. During the assembly of the shock absorber, the shock-absorbing structure 200 and the suspension structure 300 are respectively inserted into the interior of the frame body 130 from the side and exit through the bottom structure 110 and the top structure 120 respectively, thereby quickly completing the assembly of the shock absorber.

[0029] In one implementation, such as Figure 2 As shown, the top structure 110 of the connecting frame 100 includes: a mounting opening 111, which is rectangular and located in the middle of the top structure 110; and a pair of positioning openings 112, which are respectively located on both sides of a pair of long sides of the mounting opening 11. In this embodiment, the mounting opening 111 is used to pass through the suspension part of the suspension structure, while the positioning openings 112 are used to pass through the positioning part of the suspension structure to prevent it from rotating.

[0030] In an alternative implementation, the size of the positioning port 112 is smaller than the size of the mounting port to reduce the opening area of ​​the top structure, thereby increasing the strength of the top structure.

[0031] In one embodiment, please see [link to previous article]. Figure 2 The suspension structure 300 includes: a baffle plate 310, the shape and size of which match the shape and size of the mounting opening 111; an extension rod 320, one end of which is connected to the baffle plate 310 and is vertically disposed in the middle of the baffle plate 310; a hook 330, which is connected to the other end of the extension rod 320; and a positioning block 340, which is vertically disposed at both ends of the baffle plate 310 and located on both sides of the extension rod 320, the cross-sectional shape and size of which match the shape and size of the positioning opening 112.

[0032] In this embodiment, the shape and size of the mounting port 111 are designed to match the baffle plate 310, and both are rectangular. Therefore, the baffle plate 310 can be inserted from the outside of the frame body 130, and the baffle plate 310 can be engaged with the top structure 110 by rotating 90 degrees so that the baffle plate 310 can bear the main weight load. The cross-sectional shape and size of the positioning block 340 are designed to match the shape and size of the positioning port 112 to ensure that the positioning block can be inserted smoothly and reduce the shaking after insertion.

[0033] In an alternative embodiment, the baffle plate and the mounting port can also be designed to be circular, and the size of the mounting port is smaller than that of the baffle plate. In this case, when the two are inserted, they can only be inserted from the inside to the outside through the frame body, but no gap will be left after insertion, so as to achieve a sealing and dustproof effect when combined with subsequent embodiments.

[0034] In one embodiment, the positioning block 340 has a locking hole 341 on its side. For a corresponding embodiment, please refer to [link / reference needed]. Figure 3 The shock absorption device of this utility model further includes: a locking structure 400 for locking the suspension structure. The locking structure 400 includes: an L-shaped plate 410, which is arranged in pairs on the top of the connecting frame 100 and on both sides of the top surface structure 110, and a threaded hole 411 is provided near its free end. The threaded hole 411 is aligned with the positioning port 112 of the top surface structure 110; a threaded rod 420, which is threadedly connected to the L-shaped plate 410 through the threaded hole 411. A nut 421 is provided at one end of the threaded rod 420 away from the positioning port 112, and a locking block 422 is provided at the other end of the threaded rod 420 near the positioning port 112. The two are rotatably connected. The shape and size of the locking block 422 match the cross-sectional shape and size of the locking hole 341.

[0035] During use, after the connection frame 100 and the suspension structure 300 are connected, and the positioning block 340 of the suspension structure 300 extends out of the positioning port 112 on the top surface structure 110 of the connection frame 100, the threaded rod 420 can be rotated by the nut 421 to drive the locking block 422 to move horizontally and connect with the locking hole 341 on the positioning block 340, thereby achieving a rigid connection between the frame 100 and the suspension structure 300.

[0036] In one embodiment, the locking structure 400 further includes a positioning rod 430, which is arranged parallel to the threaded rod 420 and slidably connected to the L-shaped plate 410. One end of the positioning rod 430 is fixedly connected to the locking block 422. Specifically, the function of the positioning rod 430 is to prevent the locking block 422 from rotating when the threaded rod 420 rotates, thus eliminating the need to manually adjust the angle of the locking block 422 before it is inserted into the locking hole 341.

[0037] In one embodiment, the bottom structure 120 of the connecting frame 100 includes: a connecting rod hole (not shown), located in the middle of the bottom structure 120 for the connecting rod 220 of the damping structure 200 to pass through; and a limiting sleeve 121, axially vertically disposed in the middle of the bottom structure 120 and surrounding the connecting rod hole, for the damping body 210 to be embedded therein. Specifically, the limiting sleeve 121 is used to prevent the damping body 210 from sliding laterally during compression and rebound, so that the damping body 210 always maintains an upright and effective damping state.

[0038] In one embodiment, the damping structure 200 further includes a bowl-shaped baffle 230, which is connected to one end of the connecting rod 220 and is inverted and fastened to the non-abutting end of the damping body 210 to achieve a suspension connection between the connecting rod 220 and the damping body 210. The bowl-shaped baffle 230 can cooperate with the arcuate edge of the damping body 210 to ensure that the connecting rod 220 is always suspended at the center of the damping body 210, preventing friction between the two.

[0039] In one embodiment, see Figure 4 The shock absorption device of this utility model also includes a dustproof plate 500. The dustproof plate 500 is disposed around the connecting frame 100 and abuts against the top structure 110 and the bottom structure 120 to achieve a seal. The dustproof plate 500 includes: a fixed dustproof plate 510, which is disposed opposite to the connecting frame 100 and fixedly connected; and a movable dustproof plate 520, which is disposed opposite to the fixed dustproof plate 510 and detachably connected to the fixed dustproof plate 510.

[0040] In an optional embodiment, the connection between the fixed dustproof plate 510 and the movable dustproof plate 520 includes setting the width of the fixed dustproof plate 510 to be greater than the width of the frame body 130, and providing slots on both sides of the fixed dustproof plate 510 so that the movable dustproof plate 520 can be inserted into the slots to achieve a detachable connection between the two.

[0041] In one embodiment, the shock-absorbing device of this invention further includes a spring pin structure 600, which is disposed on the side attachment of the fixed dustproof plate 510 and detachably connected to the movable dustproof plate 520. The spring pin structure 600 can further limit the sliding of the movable dustproof plate 520, thereby forming a two-dimensional lock on the movable dustproof plate 520 with the slot of 510.

[0042] In an optional embodiment, please refer to Figure 5The spring pin structure 600 includes: a fixing block 610, which is fixed to the surface of the fixed dustproof plate 510; a sliding rod 620, which is parallel to the surface of the dustproof plate 510 and passes through the fixing block 610, with its two ends pointing towards the insertion slots on both sides of the fixed dustproof plate 510; a limiting plate 630, which is located near the insertion slots of the fixed dustproof plate 510 and cooperates with the fixing block 610 to limit the position of the sliding rod 620; and springs 640, which are respectively sleeved on... On the sliding rods 620 exposed on both sides of the fixed block 610, one end of which elastically abuts against the fixed block 610; the operating plate 650 is respectively sleeved on the sliding rods 620 exposed on both sides of the fixed block 610 and elastically abuts against the other end of the spring 640. In the natural state, the operating plate 650 is elastically abutted against the limiting plate 630 by the corresponding spring 640; the insertion rod 660 is vertically fixed to the other end of the operating plate 650 and is used to elastically insert into the insertion hole set near the side of the movable dustproof plate 520.

[0043] In this embodiment, the gaps on both sides of the fixed dustproof plate 510 can be made by squeezing the operating plate 650, so that the movable dustproof plate 520 can be inserted into the gap. Then, the insertion rod 660 is aligned with the insertion hole on the edge of the movable dustproof plate 520 and released, so that the insertion rod 660 is inserted into the insertion hole to fix the dustproof plate.

[0044] In an alternative embodiment, the spring pin structure 600 is disposed on the fixed dustproof plate 510 on one or both sides of the frame body 130.

[0045] In one optional embodiment, the complete structure of the shock absorber of this invention is as follows: Figure 6 As shown.
