Description

Technical Field

[0001] This utility model belongs to the field of vibration damping equipment technology, and in particular relates to an elastic damping vibration damper that is easy to assemble and disassemble. Background Technology

[0002] Elastic damping vibration isolators are one type of vibration isolator. They are vibration damping devices that combine elastic and damping elements. They are mainly used to suppress vibration, absorb impact energy, and accelerate vibration decay. Their core function is to convert mechanical vibration energy into heat energy or other dissipable energy forms through the damping effect, thereby reducing vibration amplitude, reducing noise, and improving system stability. Therefore, elastic damping vibration isolators are widely used in industrial, construction, and equipment fields due to their structural characteristics.

[0003] When performing maintenance on traditional elastic damping shock absorbers, workers cannot easily push the shock absorber housing out of the base to access the internal components. This causes the base to interfere with the maintenance work, making it inconvenient and reducing maintenance efficiency to some extent. Utility Model Content

[0006] Preferably, the lifting assembly includes a sealing cylinder connected to the inner wall of the base bottom, and the top of the inner cavity of the sealing cylinder is filled with gas. Two air guide holes are opened on one side of the sealing cylinder, and the inner cavities of the two air guide holes are connected to a common air guide pipe. A large piston is movably connected to the bottom of the inner cavity of the sealing cylinder.

Connection holes are opened on both sides of the bottom of the sealing cylinder, and suction cylinders are movably connected to the inner cavities of the two connection holes. Small pistons are movably connected to one side of the inner cavities of the two suction cylinders. Through holes are opened on one side of the two suction cylinders, and the two small pistons are movably connected to adjacent through holes near one end. Air inlets are opened on one side of the top of the two suction cylinders and on both sides of the top of the sealing cylinder, and the inner cavities of adjacent air inlets are connected to a common air intake pipe.

[0007] Preferably, each of the two small pistons is connected to a connecting plate at one end, each of the two connecting plates is provided with an electric telescopic rod on one side, and one end of each of the two electric telescopic rods is connected to the center of one side of the adjacent connecting plate. Each of the two connecting plates is connected to a support rod at one end, and one end of each of the two support rods is connected to the bottom of one side of the adjacent air intake pipe.

[0008] Preferably, the air guide tube and the two air intake tubes are each equipped with a one-way valve, and several of the one-way valves are connected to the top of the adjacent air guide tubes and the two air intake tubes.

[0009] Preferably, both of the locking components include a plurality of guide rollers connected to the inner walls on both sides of the base, and pull ropes are wound around the adjacent plurality of guide rollers.

[0012] Compared with the prior art, the embodiments of this application have the following main advantages:

[0013] 1. This utility model drives two small pistons to move to both sides inside two air intake cylinders, drawing gas from the top of the sealed cylinder cavity to the bottom of the sealed cylinder cavity. The gas drawn into the bottom of the sealed cylinder cavity can then drive the large piston to move upward, pushing the shock absorber housing out of the base for maintenance of the internal components. This achieves the purpose of conveniently pushing the shock absorber housing out of the base, thus exposing the shock absorber housing to the operator's view, facilitating quick maintenance of the internal components and avoiding interference from the base, which would otherwise cause inconvenience to the operator. This, in turn, improves the operator's maintenance efficiency to a certain extent.

[0014] 2. This utility model applies tension to two pull ropes by moving two connecting plates to both sides, thereby enabling the two pull ropes to move two T-shaped clamps to both sides and move them out of the two clamp holes on the shock absorber housing. This releases the restriction on the shock absorber housing, allowing workers to remove the shock absorber housing from the chassis for component maintenance or to replace the shock absorber springs with different elastic coefficients to adjust the damping.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides an elastic damping shock absorber that is easy to assemble and disassemble, such as... Figures 1-4 As shown, the device includes a base 1, with a base 2 connected to the top of the base 1. A chassis 8 is located at the top of the inner cavity of the base 2, and a lifting assembly 6 is located at the bottom of the chassis 8. The top of a large piston 610 inside the lifting assembly 6 is connected to the bottom of the chassis 8. By drawing gas from the top of the inner cavity of the sealing cylinder 61 into the inner cavity of the sealing cylinder 61, the gas entering the bottom of the inner cavity of the sealing cylinder 61 pushes the large piston 610 upward. When the large piston 610 moves upward, it pushes the shock absorber housing 3 out of the base 2 for maintenance. A groove is provided on the chassis 8, and the shock absorber housing 3 is located inside the groove. A round hole is provided at the top of the base 2, and the shock absorber housing 3 is movably connected to the round hole near the bottom. A locking assembly 7 is provided on both sides of the shock absorber housing 3, and a locking hole is provided at the bottom of both sides of the shock absorber housing 3. The T-shaped locking assemblies 7 on the two locking assemblies 7 are also provided. The narrower end of the T-shaped clamp 73 is engaged with the clamping hole on the vibration damper housing 3. When the vibration damper housing 3 moves upward, it applies tension to the two pull ropes 72. When the two pull ropes 72 are pulled, they pull the two T-shaped clamps 73 out of the two clamping holes on the vibration damper housing 3, releasing the restriction on the vibration damper housing 3. This makes it easier to remove the vibration damper housing 3 from the chassis 8 and replace it with vibration damping springs 9 with different elastic coefficients to adjust the damping. A stop post 4 is movably connected to the top of the inner cavity of the vibration damper housing 3. An opening is opened at the center of the top of the vibration damper housing 3. The top of the stop post 4 passes through the inner cavity of the opening and is connected to the support platform 5. The stop post 4 moves up and down inside the opening on the vibration damper housing 3 to compress or pull the vibration damping springs 9, thereby reducing the vibration generated during equipment operation.

[0023] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, the lifting assembly 6 includes a sealing cylinder 61 connected to the inner wall of the bottom of the base 2. The top of the inner cavity of the sealing cylinder 61 is filled with gas. Two air guide holes are opened on one side of the sealing cylinder 61, and the inner cavities of the two air guide holes are connected to an air guide pipe 62. A large piston 610 is movably connected to the bottom of the inner cavity of the sealing cylinder 61. A movable hole is opened at the center of the top of the sealing cylinder 61, and the large piston 610 is movably connected to the movable hole near the top. Connection holes are opened on both sides of the bottom of the sealing cylinder 61, and suction cylinders 64 are movably connected to the inner cavities of both connection holes. Small pistons 69 are movably connected to one side of the inner cavities of the two suction cylinders 64. Each side has a through hole, and the two small pistons 69 are movably connected to the adjacent through holes near one end. The top of the two air intake cylinders 64 and the top of the sealing cylinder 61 are provided with air inlets, and the inner cavities of the two adjacent air inlets are connected to the air intake pipe 63. By driving the two small pistons 69 to move to both sides inside the two air intake cylinders 64, the gas at the top of the inner cavity of the sealing cylinder 61 is drawn into the inner cavity of the sealing cylinder 61. The gas drawn into the bottom of the sealing cylinder 61 then pushes the large piston 610 upward, which facilitates the large piston 610 to push the chassis 8 and the shock absorber housing 3 out of the base 2 for maintenance.

[0024] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, each of the two small pistons 69 is connected to a connecting plate 66 at one end. Each of the two connecting plates 66 is provided with an electric telescopic rod 65 on one side, and one end of each electric telescopic rod 65 is connected to the center of one side of the adjacent connecting plate 66. Each of the two connecting plates 66 is connected to a support rod 67 at one end, and one end of each support rod 67 is connected to the bottom of one side of the adjacent suction pipe 63. By energizing the two electric telescopic rods 65, the two connecting plates 66 are moved to the sides or closed, thereby causing the two small pistons 69 to move to the sides inside the two suction cylinders 64 to achieve the suction operation, or causing the two small pistons 69 to close inside the two suction cylinders 64 to achieve the pushing operation.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3As shown, one-way valves 68 are provided on the gas guide pipe 62 and the two suction pipes 63, and several one-way valves 68 are connected to the top of the adjacent gas guide pipe 62 and the two suction pipes 63. The one-way valves 68 on the gas guide pipe 62 and the two suction pipes 63 are used to achieve the one-way nature of the gas. That is, the one-way valve 68 on the gas guide pipe 62 can only introduce the gas at the bottom of the inner cavity of the sealing cylinder 61 into the top of the inner cavity of the sealing cylinder 61 through the gas guide pipe 62, and the one-way valves 68 on the two suction pipes 63 can only draw the gas at the top of the inner cavity of the sealing cylinder 61 into the bottom of the inner cavity of the sealing cylinder 61 through the two suction pipes 63.

[0026] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, both locking components 7 include several guide rollers 71 connected to the inner walls on both sides of the base 2, and pull ropes 72 are wound around the adjacent guide rollers 71. The bottom end of each pull rope 72 is connected to the top of one side of the adjacent connecting plate 66, and the top end of each pull rope 72 is connected to a T-shaped locking rod 73. A support plate 74 is sleeved on the wider end of each T-shaped locking rod 73 near the T-shaped structure, and the top of each support plate 74 is connected to the top inner wall of the base 2. By moving the two connecting plates 66 to both sides, a pulling force is applied to the two pull ropes 72, thereby pulling the two T-shaped locking rods 73 out of the two locking holes on the shock absorber housing 3 and releasing the restriction on the shock absorber housing 3.

[0027] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a return spring 75 is fitted on each of the two T-shaped clamps 73 near the wider end of the T-shaped structure. One side of each return spring 75 is connected to the wider end of the T-shaped structure of the adjacent T-shaped clamp 73, and the other side of each return spring 75 is connected to the bottom of the adjacent support plate 74. Through the elastic action of the two return springs 75, when the tension on the two pull ropes 72 disappears, the two return springs 75 can push the two T-shaped clamps 73 back into the clamping holes on the shock absorber housing 3, thereby limiting the position of the shock absorber housing 3 and thus reassembling and fixing the shock absorber housing 3 and the chassis 8 together for use.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, both the top of the chassis 8 and the bottom of the support column 4 are provided with placement slots, and the two placement slots are equipped with a damping spring 9. The vibration generated by the equipment placed on the support platform 5 during operation is reduced by the cooperation of the support column 4 and the damping spring 9.

[0029] In this embodiment, when the elastic damper is in use, the operator places it under the equipment via the base 1, ensuring that the support platform 5 is in contact with the bottom of the equipment. This allows the vibration generated during equipment operation to be reduced through the combined action of the abutment column 4 and the damping spring 9. When the operator needs to push the damper housing 3 out of the base 2 to perform maintenance on the internal components of the damper housing 3, the operator activates the two electric telescopic rods 65 via an external power source and then activates them via a handheld controller. When energized, the two electric telescopic rods 65 can drive two small movable rods via two connecting plates 66. The plug 69 moves to both sides inside the two suction cylinders 64, thereby drawing the gas from the top of the inner cavity of the sealing cylinder 61 to the bottom of the inner cavity of the sealing cylinder 61, which drives the large piston 610 to move upward, pushing the shock absorber housing 3 out of the base 2 to perform maintenance work on the components inside the shock absorber housing 3. At the same time, when the connecting plate 66 moves to both sides, it can apply tension to the two pull ropes 72, which can then drive the two T-shaped locking rods 73 to move to both sides and move out from the two locking holes on the shock absorber housing 3, thereby releasing the restriction on the shock absorber housing 3, making it easier for the staff to remove the shock absorber housing 3 from the chassis 8 for component maintenance work.
