Description

Technical Field

[0001] This utility model relates to the field of vibration isolator technology, and in particular to a compact motion load vibration isolator. Background Technology

[0002] In modern industrial equipment, precision instruments, and construction engineering, vibration isolators are key components for suppressing vibration transmission and ensuring stable equipment operation. Their performance and installation accuracy directly affect the equipment's working efficiency and service life. With the continuous improvement of equipment manufacturing precision and the increasing complexity of installation environments, higher requirements are placed on the installation and adjustment functions of vibration isolators.

[0003] Traditional vibration isolators mostly adopt a fixed installation structure. During installation, the correspondence between the equipment installation position and the vibration isolator needs to be precisely designed in advance. Once there is a slight deviation in the installation position, it is difficult to make effective adjustments. Often, it is necessary to disassemble, reposition, and reinstall, which not only consumes a lot of manpower and resources, but also significantly prolongs the construction period and affects the progress of the project. Utility Model Content

[0004] To overcome the shortcomings mentioned in the background art, the technical problem is to provide a compact motion load vibration isolator.

[0005] The technical solution is as follows: A compact motion load vibration isolator includes a connecting cylinder, a telescopic cylinder, a sliding frame, a damping spring, a damping device, a connecting plate, a locking rod, a torsion spring, and a drive assembly. The telescopic cylinder is slidably connected to the connecting cylinder, and the sliding frame is slidably connected inside the connecting cylinder. The top of the sliding frame is connected to the top of the telescopic cylinder. A damping spring is connected between the connecting cylinder and the telescopic cylinder, and the damping spring is coaxially sleeved on the outside of the sliding frame. A damping device is provided between the bottom of the sliding frame and the bottom of the connecting cylinder. A connecting plate is locked to the bottom of the connecting cylinder. Locking rods are rotatably connected to the front and rear sides of the connecting plate. The inner side of the locking rod is machined with a bevel. A locking groove adapted to the locking rod is opened at the bottom of the connecting cylinder, and the locking rod and the locking groove form a locking fit. A torsion spring is installed at the rotatable connection between the locking rod and the connecting plate. A drive assembly is provided on the connecting plate.

[0006] Furthermore, the shock-absorbing springs are made of piano wire and have a galvanized passivation treatment on the surface.

[0007] Furthermore, the drive assembly includes a first screw and a trapezoidal block. The first screw is rotatably connected to the middle of the connecting disk, and the trapezoidal block is threadedly connected to the middle of the first screw. The trapezoidal block is slidably connected to the bottom of the connecting disk, and the front and rear side walls of the trapezoidal block and the inner inclined surface of the clamping rod form a wedge-shaped transmission structure.

[0008] Furthermore, it also includes a fixed block, a sliding frame, a base, and an adjustment component. The fixed block is connected to the bottom of the connecting plate, the sliding frame is slidably connected to the outside of the fixed block, the base is slidably connected to the outside of the sliding frame, and the adjustment component is provided on the base.

[0009] Furthermore, the base is made of ductile iron, and the surface of the base is equipped with reinforcing ribs.

[0010] Furthermore, the adjustment assembly includes a second screw and a third screw. The second screw is threadedly connected to the right side of the base, and the second screw is rotatably connected to the sliding frame. The third screw is rotatably connected to the sliding frame, and the fixing block is threadedly connected to the third screw.

[0011] The beneficial effects are as follows: 1. The adjustment component adopts an independent drive design for the second and third screws: during horizontal adjustment, the second screw drives the sliding frame to move along the base through thread transmission; during vertical adjustment, the third screw drives the fixed block to move back and forth in the sliding frame, realizing bidirectional fine adjustment of the X / Y axis of the connecting cylinder and the telescopic cylinder, which significantly improves the equipment installation efficiency and reduces manual alignment errors.

[0012] 2. The design of the first screw, trapezoidal block and locking rod of the drive component enables quick disassembly and assembly without a base: rotating the first screw can push the locking rod outward through the inclined surface of the trapezoidal block, releasing the engagement with the connecting cylinder slot, and the upper component can be separated without disassembling the base, thus shortening maintenance time.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example: A compact vibration isolator for moving loads, such as Figures 1-3As shown, the assembly includes a connecting cylinder 1, a telescopic cylinder 2, a sliding frame 3, a damping spring 4, a damping device 5, a connecting disc 6, a locking rod 7, a torsion spring 8, and a drive assembly. The telescopic cylinder 2 is slidably connected to the connecting cylinder 1, and the sliding frame 3 is slidably connected inside the connecting cylinder 1. The top of the sliding frame 3 is connected to the top of the inner part of the telescopic cylinder 2. A damping spring 4 is connected between the connecting cylinder 1 and the telescopic cylinder 2. The damping spring 4 is coaxially sleeved on the outside of the sliding frame 3 to absorb vibration energy. A damping device 5 is provided between the bottom of the sliding frame 3 and the bottom of the inner part of the connecting cylinder 1 to dissipate vibration through viscous damping effect. The energy system includes a connecting cylinder 1 with a connecting plate 6 attached to its bottom. Connecting rods 7 are rotatably connected to the front and rear sides of the connecting plate 6. The inner side of the connecting rods 7 is machined with an inclined surface. A slot is provided at the bottom of the connecting cylinder 1 to fit the connecting rods 7. The connecting rods 7 and the slots engage to achieve rapid positioning and fixation of the connecting cylinder 1 and the connecting plate 6. A torsion spring 8 is installed at the rotatable connection between the connecting rods 7 and the connecting plate 6 to provide a reset torque for the connecting rods 7. A shock-absorbing spring 4 is made of piano wire and has a galvanized passivation treatment to ensure stable elastic performance. A drive assembly is provided on the connecting plate 6.

[0020] like Figure 3 As shown, the drive assembly includes a first screw 9 and a trapezoidal block 10. The first screw 9 is rotatably connected to the middle of the connecting disk 6, and the trapezoidal block 10 is threadedly connected to the middle of the first screw 9. The trapezoidal block 10 is slidably connected to the bottom of the connecting disk 6. The front and rear side walls of the trapezoidal block 10 and the inner inclined surface of the clamping rod 7 form a wedge-shaped transmission structure. By rotating the first screw 9, the trapezoidal block 10 is driven to move, thereby controlling the opening and closing action of the clamping rod 7.

[0021] like Figure 1 and Figure 4 As shown, it also includes a fixing block 11, a second screw 12, a sliding frame 13, a third screw 14, and a base 15. The fixing block 11 is welded to the bottom of the connecting plate 6. The sliding frame 13 is slidably connected to the outside of the fixing block 11. The base 15 is slidably connected to the outside of the sliding frame 13. The base 15 is made of ductile iron and has a reinforcing rib structure on its surface to improve the structural strength and deformation resistance of the base 15. The second screw 12 is threadedly connected to the right side of the base 15. The second screw 12 is rotatably connected to the sliding frame 13 and can drive the sliding frame 13 to move laterally along the base 15. The third screw 14 is rotatably connected to the sliding frame 13. The fixing block 11 is threadedly connected to the third screw 14, which can realize the longitudinal adjustment of the fixing block 11 along the sliding frame 13.

[0022] First, the vibration isolator base 15 is rigidly fixed to the foundation structure using high-strength bolts or welding to form a stable support system. The telescopic cylinder 2, as the equipment connection end, needs to be precisely aligned with the equipment installation surface. When fixing the telescopic cylinder 2, it is necessary to ensure that the telescopic cylinder 2 is precisely aligned with the equipment fixing area. For ease of installation, the area above the connecting plate 6 can be slightly adjusted individually. When performing lateral position calibration, the second screw 12 is rotated clockwise or counterclockwise to make the sliding frame 13 move horizontally along the base 15, simultaneously driving the fixing block 11, connecting plate 6, connecting cylinder 1, and telescopic cylinder 2 to complete the lateral adjustment. If longitudinal positioning is required, the third screw 14 is operated to drive the fixing block 11 to move back and forth within the sliding frame 13, thereby achieving longitudinal fine adjustment of components such as the connecting cylinder 1 and telescopic cylinder 2. By independently adjusting the X / Y axes, the millimeter-level positioning accuracy between the telescopic cylinder 2 and the equipment installation interface is ensured. When the equipment vibrates during operation, the excitation force is transmitted to the internal vibration damping structure through the telescopic cylinder 2. The sliding frame 3 acts as the force transmission center, synchronously transmitting the vibration energy to the damping spring 4 and the damping device 5. The damping spring 4 absorbs the vibration kinetic energy through elastic deformation, converting mechanical energy into elastic potential energy. At the same time, the damping device 5 utilizes the energy dissipation characteristics of viscous fluid or elastic damping material to convert vibration energy into heat energy dissipation. The two work together to form a composite vibration damping mechanism, effectively attenuating the transmission of equipment vibration and ensuring the stability of the foundation structure and the surrounding environment. During equipment maintenance, operators can disassemble the non-base 15 using the drive assembly. By rotating the first screw 9 clockwise, the trapezoidal block 10 is driven to move radially to the right using the self-locking transmission characteristic of the trapezoidal thread. The inclined surface of the trapezoidal block 10 interacts with the wedge-shaped structure inside the locking rod 7, forcing the locking rod 7 to overcome the preload of the torsion spring 8 and rotate outward, releasing the engagement with the slot of the connecting cylinder 1. This allows for the rapid separation of the connecting cylinder 1 and the telescopic cylinder 2. During reinstallation, the connecting cylinder 1 is re-engaged with the connecting plate 6, and then the first screw 9 is rotated in the opposite direction to return the trapezoidal block 10 to its original position, releasing the constraint on the locking rod 7. The torsion spring 8 quickly drives the locking rod 7 to reset and accurately embed into the slot of the connecting cylinder 1. The self-locking characteristic of the first screw 9 ensures the structural reliability of the vibration isolator during equipment operation.
