Description

Technical Field

[0001] This utility model belongs to the field of vibration damper technology, specifically relating to a novel spring vibration damper with transport protection. Background Technology

[0002] Spring vibration dampers are vibration damping devices used to isolate mechanical vibration and noise transmission. They are usually installed between the unit base and the foundation. They absorb vibration energy through highly elastic helical springs, significantly reducing vibration. They are commonly used in air conditioning units or other large equipment.

[0003] Currently, equipment is typically transported to the work site after the spring shock absorbers are installed. During transportation, the lateral inertial forces, side impact forces, and cumulative vibrations caused by vehicle acceleration / deceleration, turning, bumping, tilting, and loading / unloading vibrations act between the upper and lower connecting surfaces of the shock absorber springs, causing relative displacement between the upper and lower seats of the spring shock absorber and generating shear forces. These shear forces during transportation can cause the spring centerline to shift, making it prone to bending or torsion after installation, leading to spring clipping and posing a risk of plastic deformation or breakage during subsequent use.

[0004] Currently, our company uses studs on both sides to fix the upper and lower connecting surfaces of the spring, resisting shear forces during transportation and preventing the spring from dislodging or being damaged. The existing structure has the following drawbacks: 1. If the force is too great during transportation, the stud will come off the spring damper, causing the spring damper to lose its shear resistance. 2. The overall structure is assembled, which results in insufficient integrity and makes it easy for nuts to come loose at the joints, causing damage. 3. The bottom mounting structure is not stable enough. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies. The problem to be solved is that existing spring vibration dampers with transport protection are prone to the studs coming loose during transport and easily detaching at mechanical connections during operation, resulting in insufficient base stability. This invention proposes a novel spring vibration damper with transport protection, improving the connection structure between the base and the studs. Furthermore, it integrates the top connecting plate with the spring and base into a single unit, resulting in stronger overall structure and a longer service life.

[0006] The present invention adopts the following technical solution: a novel spring shock absorber with transport protection, comprising: The base includes a spring attachment seat and a mounting plate. There are two mounting plates located on either side of the spring attachment seat. The plane of the spring attachment seat is higher than the mounting plate. The mounting plate is provided with mounting holes for connecting the spring vibration damper to the equipment mounting foundation. The top connecting plate includes a central base plate and two symmetrical connecting pieces. The plane of the connecting pieces is lower than the plane of the central base plate. The central base plate is connected to the equipment. The connecting pieces are provided with stud connection holes.

[0007] A spring is located between the base and the top connecting plate, with its two ends welded to the base and the top connecting plate, respectively.

[0008] There are two sets of stud assemblies, symmetrically arranged on both sides of the spring, which can be detachably connected to the top connecting plate and the base. The stud assembly includes a stud and nuts at both ends of the stud. The upper end of the stud is locked in the stud connection hole of the top connecting plate, and the lower end is locked on the base.

[0009] According to another embodiment of the utility model or any of the foregoing embodiments, the base has a symmetrical structure in the shape of a "Z" and the spring attachment seat is connected to the mounting plates on both sides by vertical plates.

[0010] According to another embodiment of the utility model or any of the foregoing embodiments, the spring damper has two symmetrical opening slots on two sides of the base that are not connected to the mounting plate. The opening slots are elongated, and one end of the stud assembly is locked in the opening slot.

[0011] According to another embodiment of the utility model or any of the foregoing embodiments, the spring damper has a central seat plate of the top connecting plate with a device connection hole, and the device is locked to the top connecting plate by bolts or screws.

[0012] According to another embodiment of the utility model or any of the foregoing embodiments, the spring vibration damper includes two sets of first nuts, toothed washers, and second nuts. The first nuts and second nuts are respectively located on both sides of the connecting plate of the top connecting plate or the spring attachment seat of the base. The toothed washers are installed between the first nuts and the connecting plate or the spring attachment seat. The toothed washers increase friction and a small bit of engagement force by embedding their teeth into the contact surface, thereby preventing the nuts from loosening under vibration or impact conditions.

[0013] The beneficial effects of this utility model are: 1. This utility model discloses a novel spring shock absorber with transport protection. The spring, base, and top connecting plate are welded into a single structure, which can better withstand the impact, bumps, and lateral loads during transportation. There is no relative movement at the contact surfaces, reducing fatigue points and extending the service life. It can avoid transport protection failure caused by loosening after bumps, has greater structural strength, and is more cost-effective. 2. The opening slot of the top connecting plate has been improved to a hole structure to prevent the studs from loosening during transportation, thereby improving the transportation protection effect and service life of the spring shock absorber; 3. The base of this utility model is connected to studs and springs. Compared with traditional spring dampers of the same type, it has higher structural strength and the stud connection is less prone to stress concentration and deformation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , 3 As shown, a novel spring vibration damper with transport protection includes: a base 100, a top connecting plate 300, a spring 400, and a stud assembly 200.

[0017] like Figure 3 , 5As shown, the base 100 includes a spring 400 attachment seat and mounting plates. Two mounting plates are located on either side of the spring 400 attachment seat, with the plane of the spring 400 attachment seat higher than the mounting plates. Mounting holes 101 are provided on the mounting plates for connecting the spring damper to the equipment mounting foundation. The base 100 has a Z-shaped symmetrical structure, with the spring 400 attachment seat connected to the mounting plates on both sides via vertical plates. Two symmetrical open slots 102 are provided on the two sides of the base 100 not connected to the mounting plates. The open slots 102 are elongated, and one end of the stud assembly 200 is locked within the open slot 102. The open slots 102 facilitate the installation and removal of the studs 204. Since the top connecting plate 300 of the spring damper is connected to the equipment, and the base 100 is relatively less affected by displacement, a design with an open bottom and a closed top is adopted to ensure ease of installation.

[0018] like Figure 2 , 3 As shown in Figures 5 and 6, the top connecting plate 300 includes a central base plate and two symmetrical connecting pieces. The plane of the connecting pieces is lower than the plane of the central base plate. The central base plate is connected to the equipment, and the connecting pieces are provided with stud connection holes 301. When the equipment is subjected to lateral inertial forces and lateral impact forces caused by vehicle acceleration and deceleration, turning, bumping, tilting, loading and unloading vibrations, the equipment is prone to movement, which can easily cause the upper part of the stud 204 to shift. The top connecting plate 300 is provided with stud connection holes 301 to prevent the upper part of the stud 204 from detaching. The central base plate of the top connecting plate 300 is provided with equipment connection holes 302, allowing the equipment to be locked onto the top connecting plate 300 using bolts or screws. When the bolts are directly tightened, the spring damper cannot adjust the height of the equipment. The equipment height can be easily adjusted using a double-ended screw and two nuts, facilitating leveling.

[0019] like Figure 1 , 2 As shown in Figures 3 and 5, spring 400 is located between base 100 and top connecting plate 300, with both ends of spring 400 welded to base 100 and top connecting plate 300 respectively. Welding improves the overall structure and stability, preventing spring 400 from shifting, loosening, or becoming eccentric under long-term vibration or transportation impact, ensuring a long-lasting and stable vibration reduction effect. Under ordinary embedding or clamping methods, the ends of spring 400 are prone to micro-displacement or rotation during long-term vibration, resulting in uneven force on spring 400 and axial misalignment; after welding, the upper and lower end faces are rigidly constrained, and spring 400 maintains a vertical working state, avoiding lateral forces. At the same time, welding forms a rigid whole, which can better withstand the impact, bumps, and lateral loads during transportation. Sliding or impact on the end face of spring 400 can cause local wear and stress concentration, shortening its lifespan. After welding, there is no relative movement of the contact surfaces, reducing fatigue points and extending the service life. A vibration-damping rubber pad (500) is fitted onto the center seat plate of the top connecting plate (300).

[0020] like Figure 1 , 4 As shown, there are two sets of stud assemblies 200, symmetrically arranged on both sides of the spring 400, detachably connecting the top connecting plate 300 and the base 100. The stud assembly 200 includes a stud 204 and nuts at both ends of the stud 204. The upper end of the stud 204 is locked in the stud connection hole 301 of the top connecting plate 300, and the lower end is locked on the base 100. The stud assembly 200 includes two sets of first nuts 201, toothed washers 202, and second nuts 203. The first nuts 201 and second nuts 203 are respectively located on both sides of the connecting plate of the top connecting plate 300 or the attachment seat of the spring 400 on the base 100. The toothed washers 202 are installed between the first nuts 201 and the connecting plate or the attachment seat of the spring 400. The toothed washers 202 increase friction and a small bit of engagement force by embedding their teeth into the contact surface, thereby preventing the nuts from loosening under vibration or impact conditions. Figure 5 As shown, the stud assembly 200 needs to be removed after the equipment is transported to the working environment and installed. At this time, the spring 400 plays a shock-absorbing role.

[0021] The working principle of this utility model: Traditional spring vibration dampers with transport protection suffer from insufficient stability of the base 100, with only two connection holes between it and the equipment's mounting foundation. This invention allows for four or more connection holes in the base 100. Furthermore, the spring 400, top connecting plate 300, and base 100 are welded together to form a rigid whole. In traditional clamping or pre-pressing installation methods, the ends of the spring 400 may slide or rotate, causing its working axis to shift. After welding, the spring 400, base 100, and connecting plate form a rigid whole, eliminating micro-displacement at the contact interface. Combined with the detachable limiting stud assembly 200, the upper and lower end faces of the spring 400 are rigidly constrained during transport, preventing lateral shearing and axial displacement. During operation, after removing the stud 204, the spring 400 can vibrate freely, achieving its vibration damping function. With the toothed washer 202 for anti-loosening and the reinforcing plate for deformation resistance, the entire unit possesses impact resistance, fatigue resistance, and deformation resistance.

[0022] To address the issue that the open slot 102 is prone to loosening due to bumps during transportation, a hole structure was modified at the connection between the equipment and the top connecting plate 300, which can effectively prevent the upper part of the stud 204 from loosening.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and characteristics of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
