Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbing equipment, and more specifically to a novel steel spring shock isolator. Background Art

[0002] In the fields of buildings, bridges, equipment, vehicles, etc., the vibration and impact caused by the external environment or during use often have an adverse effect on the safety, stability and service life of the structure and equipment. In order to effectively reduce and isolate these vibrations and impacts, seismic isolators are widely used as a vibration reduction device.

[0003] Traditional isolators include rubber isolators, metal spring isolators, etc. These isolators can reduce vibration to a certain extent, but with the continuous improvement of requirements, traditional isolators have certain limitations in performance. For example, the vibration reduction effect of rubber isolators will decrease under high-frequency vibration, and metal spring isolators are prone to fatigue damage after long-term use. Moreover, traditional isolators often lack sufficient adjustment capabilities when facing complex and changeable vibration environments, making it difficult to meet diverse vibration reduction needs.

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1-4 A new type of steel spring 8 seismic isolator includes a fixed seat 1 and a base 7. A movable seat 6 is provided above the base 7. A fixed seat 1 is provided above the movable seat 6. A spring 8 is installed between the fixed seat 1 and the movable seat 6. A height limiting member 5 is provided on both sides of the spring 8. A round table 4 is installed on the movable seat 6. The round table 4 and the height limiting member 5 are welded as a whole. A mounting plate 10 is connected between the fixed seat 1 and the spring 8. A hydraulic cylinder 9 is connected to the right side of the height limiting member 5. A hydraulic pump 11 is installed above the hydraulic cylinder 9.

[0029] In some embodiments, a liquid damper 2 is disposed inside the fixing seat 1, and a damping hole 3 is disposed at the bottom of the liquid damper 2. The spring 8 is a cylindrical helical spring 8, and the liquid damper 2 is filled with silicone oil.

[0030] In some embodiments, a regulating valve 501 is installed on the height limiting member 5, and the regulating valve 501 is used to adjust the height of the height limiting member 5, and the height limiting member 5 is retractable. A high-pressure oil pipe 12 is installed between the hydraulic cylinder 9 and the hydraulic pump 11, and a hydraulic valve 13 is installed on the high-pressure oil pipe 12.

[0031] When an external force acts on the fixed seat 1, the fixed seat 1 transmits the force to the movable seat 6 below it. The movable seat 6 absorbs and releases part of the external force through the spring 8 to achieve a shock-absorbing effect. The spring 8 is a cylindrical helical spring that can effectively absorb and buffer vibration.

[0032] The spring 8 is provided with height limiting parts 5 on both sides, which ensures that the spring does not exceed its designed working range during the force application process. The regulating valve 501 installed on the height limiting part 5 can adjust the height of the height limiting part, thereby controlling the compression stroke of the spring, providing additional limit and protection functions. The height limiting part 5 is a retractable structure, which can be adjusted in height and retracted as needed.

[0033] The right side of the height limiter 5 is connected to a hydraulic cylinder 9, which is connected to a hydraulic pump 11 through a high-pressure oil pipe 12, and the delivery and regulation of the hydraulic oil are controlled by a hydraulic valve 13. When the damping characteristics of the system need to be adjusted, the hydraulic pump 11 can provide pressure to the hydraulic cylinder 9 to make the hydraulic cylinder expand and contract, thereby changing the height and position of the height limiter 5. The design of this hydraulic system can provide more precise height and damping adjustment and improve the performance of the seismic isolator.

[0034] A liquid damper 2 is provided inside the fixing base 1, and the inside of the liquid damper 2 is filled with silicone oil. The liquid damper 2 adjusts the flow of liquid through the damping hole 3, thereby providing an additional damping effect. When the fixing base 1 is vibrated, the silicone oil in the liquid damper 2 flows through the damping hole 3, generating viscous resistance, further reducing the transmission of vibration.

[0035] This new steel spring isolator provides a multi-level, multi-mode vibration control and shock absorption solution through the combined action of springs, height limiters, hydraulic systems and liquid dampers. The springs are responsible for the main vibration buffering, the height limiters provide protection and adjustment functions, the hydraulic system allows precise control of vibration characteristics, and the liquid dampers further enhance the shock absorption effect of the system.

[0036] When in use: Place the base 7 on the base that needs to be isolated and ensure that it is stable. Install the movable seat 6 above the base 7, ensuring that the movable seat can move freely but does not deviate from the position of the base. Install the spring 8 between the movable seat 6 and the fixed seat 1, ensuring that the spring can provide sufficient elastic support and return to its original position. Install the height limiter 5 on both sides of the spring 8, and the height limiter should be fixed on the movable seat 6 and the round table 4. Connect the hydraulic cylinder 9 to the right side of the height limiter 5. Install the hydraulic pump 11 above the hydraulic cylinder 9, and connect the hydraulic cylinder and the hydraulic pump through the high-pressure oil pipe 12. Install the hydraulic valve 13 on the high-pressure oil pipe 12 to control the hydraulic flow. Install the liquid damper 2 inside the fixed seat 1, and ensure that the damping hole 3 is located at the bottom of the liquid damper. Ensure that the liquid damper is filled with enough silicone oil to achieve the damping effect. Use the regulating valve 501 on the height limiter 5 to adjust the height of the height limiter to ensure that the height limiter can be extended and retracted as needed to meet different isolation requirements.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be covered by the protection scope of the utility model.
