Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vibration reduction equipment technology, specifically to a vibration reduction structure for equipment in a steel structure factory building. Background Technology
[0002] Vibration reduction has always been a problem to be solved in industrial projects. Any equipment in use vibrates to some extent. In modern industrial production, various machines operate within factory buildings, and when the vibrations they generate are significant, resonance can easily occur, causing factory vibrations and leading to safety issues. This is especially true in steel-structured factory buildings, where resonance problems are more likely to arise. In recent years, with the development of new energy vehicles, the demand for ternary lithium-ion batteries has been increasing, placing higher demands on the production process of ternary cathode materials. Currently, with the development of intelligent technology, factory management is becoming increasingly intelligent, typically equipped with monitoring equipment to monitor the status of ternary cathode material production equipment and make corresponding adjustments. To further reduce the safety of equipment in steel-structured factories and ensure its effective use, research and development are urgently needed to reduce vibrations of equipment within steel-structured factory buildings. Therefore, we propose a vibration-damping structure suitable for ternary cathode material process equipment in steel-structured factory buildings. Utility Model Content
[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a vibration damping structure for equipment in a steel structure factory building, which can monitor the weight of the equipment and detect its vibration in real time. By coordinating the vibration damping structure with monitoring elements, the operational safety of the equipment is improved. This application provides the following technical solution:
[0004] It includes an upper connecting steel plate, a lower connecting steel plate, and a rubber shock absorber connected between the upper connecting steel plate and the lower connecting steel plate. The rubber shock absorber has a frame steel plate embedded at intervals. The upper connecting steel plate is provided with a weighing element, and the rubber shock absorber is provided with a vibration detection element.
[0005] The rubber shock absorber has an internal cavity to facilitate compression deformation and absorption of impact energy.
[0006] The steel frame plate has several holes. This reduces weight while maintaining rigidity, and during manufacturing, rubber can be flowed into the holes to form a physical interlock.
[0007] The outer edge of the frame steel plate is provided with reinforcing ribs to enhance its load-bearing capacity.
[0008] The rubber shock absorber includes a highly elastic rubber layer vulcanized and bonded to the frame steel plate, and a weather-resistant rubber layer covering the frame steel plate and the highly elastic rubber layer. The highly elastic rubber layer provides excellent shock absorption and energy absorption capabilities; the weather-resistant rubber layer allows it to withstand extreme environments such as high temperatures and corrosion.
[0009] The rubber shock absorber also includes a high-hardness rubber layer disposed above and / or below the high-elasticity rubber layer. The high-hardness rubber layer is used to disperse pressure, enhance load-bearing capacity, and prevent excessive deformation.
[0010] Both the upper connecting steel plate and the lower connecting steel plate are provided with grooves that match the rubber shock absorber, and the rubber shock absorber is installed into the grooves. This makes the connection between the rubber shock absorber and the upper connecting steel plate and the lower connecting steel plate more stable.
[0011] The rubber shock absorber is bonded to the upper connecting steel plate and the lower connecting steel plate by cold vulcanizing adhesive.
[0012] The weighing element is a pressure sensor, and the vibration detection element is an acceleration sensor.
[0013] The pressure sensor is fixed to the upper surface of the upper connecting steel plate, and the acceleration sensor is embedded in the outer wall of the rubber shock absorber.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] There are multiple ways to design the load-bearing capacity and vibration damping capacity of rubber shock absorbers, specifically including: the spacing of the skeleton steel plates, the thickness of the skeleton steel plates, the location, quantity, and shape of the holes in the skeleton steel plates, the thickness and width of the reinforcing ribs of the skeleton steel plates, the selection and distribution of the rubber material inside the rubber shock absorber, and the size and shape of the cavity inside the rubber shock absorber. By changing the above factors, the load-bearing capacity and vibration damping capacity of the rubber shock absorber can be designed in a diversified way. By setting up weighing elements and vibration detection elements, if the effect of the rubber shock absorber is found to be poor during use, the weight information and vibration information of the machine equipment can be collected. A damping structure with sufficient load-bearing capacity and vibration damping effect can be selected or designed in a targeted manner to avoid the resonance range or reduce the resonance effect of the vibration generated by the machine equipment.
[0016] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0024] Please refer to Figure 1-4 As shown, this utility model provides a vibration damping structure for equipment inside a steel structure factory building.
[0025] It includes an upper connecting steel plate 1, a lower connecting steel plate 2, and a rubber shock absorber 3 connected between the upper connecting steel plate 1 and the lower connecting steel plate 2. The rubber shock absorber 3 has a frame steel plate 31 embedded at intervals. The upper connecting steel plate 1 is equipped with a weighing element 4, and the rubber shock absorber 3 is equipped with a vibration detection element 5.
[0026] The weighing element 4 and vibration detection element 5 can be glued or embedded on the upper connecting plate 1 and the rubber shock absorber 3. Both the weighing element 4 and the vibration detection element 5 are connected to the corresponding external monitoring system. The monitoring system can display the measured parameters. In this embodiment, the weighing element 4 is a pressure sensor used to monitor the weight of the equipment, and the vibration detection element 5 is an acceleration sensor used to detect the vibration of the equipment. The pressure sensor is fixed on the upper surface of the upper connecting steel plate 1, and the acceleration sensor is embedded in the outer wall of the rubber shock absorber 3. The material of the frame steel plate 31 can be 304 / 316 stainless steel or spring steel.
[0027] The rubber shock absorber 3 has a cavity 32 inside.
[0028] The frame steel plate 31 has several holes. The holes on the frame steel plate 31 can be designed as a grid or honeycomb pattern, and the forms of the holes include, but are not limited to, through holes, semi-through holes, grooves, and threaded holes.
[0029] The outer edge of the frame steel plate 31 is provided with reinforcing ribs 311.
[0030] The rubber shock absorber 3 includes a highly elastic rubber layer 33 that is vulcanized and bonded to the frame steel plate 31, and a weather-resistant rubber layer 34 that covers the frame steel plate 31 and the highly elastic rubber layer 33.
[0031] The rubber shock absorber 3 also includes a high-hardness rubber layer 35 disposed on the upper and / or lower part of the high-elasticity rubber layer 33.
[0032] The high-elasticity rubber layer 33 can be made of natural rubber, styrene-butadiene rubber, or polyurethane; the weather-resistant rubber layer 34 can be made of silicone or fluororubber; and the high-hardness rubber layer 35 can be made of chloroprene rubber or nitrile rubber, generally requiring a Shore hardness of 70A or higher.
[0033] The manufacturing method can be as follows: first, the stainless steel skeleton plate 31 is pre-formed; then the skeleton plate 31 is placed into the mold, and rubber compound is injected in stages to form the above-mentioned layered structure.
[0034] High-temperature and high-pressure vulcanization tightly bonds the rubber to the stainless steel.
[0035] Both the upper connecting steel plate 1 and the lower connecting steel plate 2 are provided with grooves that match the rubber shock absorber 3, and the rubber shock absorber 3 is installed into the grooves.
[0036] The rubber shock absorber 3 is bonded to the upper connecting steel plate 1 and the lower connecting steel plate 2 using cold vulcanizing adhesive. A layer of metallic primer is applied to the surfaces of the upper connecting steel plate 1 and the lower connecting steel plate 2. The mixed cold vulcanizing adhesive is then applied to the bonding surfaces of the upper connecting steel plate 1 and the lower connecting steel plate 2. After drying, another layer is applied. The bonding surfaces of the rubber are also coated with a layer of cold vulcanizing adhesive. The surfaces are then compacted using a rubber mallet or a compaction roller.
[0037] Furthermore, the upper connecting steel plate 1 and the lower connecting steel plate 2 are provided with bolt holes for connection with machinery and equipment, and are connected by bolts. After selecting a vibration damping structure that meets the vibration damping requirements, it can also be welded to the machinery and equipment.
[0038] Weighing element 4 is a pressure sensor, and vibration detection element 5 is an acceleration sensor.
[0039] The pressure sensor is fixed to the upper surface of the upper connecting steel plate 1, and the acceleration sensor is embedded in the outer wall of the rubber shock absorber 3.
[0040] The weighing element 4 and the vibration detection element 5 are connected to an external monitoring system via signal lines to transmit equipment weight and vibration data in real time.
[0041] In practice, the monitoring system uses the data from the weighing element 4 and the vibration detection element 5 to judge the equipment's operating status in real time and issue alarm signals. At the same time, it can also design various vibration damping structures first, and then conduct parameter tests on the vibration damping structures through experiments and / or finite element analysis to obtain various vibration damping structures with different load-bearing capacity parameters and shock absorption capacity parameters. These structures are then numbered and selected for installation according to actual needs.
[0042] The experiments include: static testing: measuring the maximum load-bearing capacity (such as compressive strength and shear strength).
[0043] Dynamic testing: Vibration table test: Simulates the frequency response (such as transmissibility curve) under actual working conditions.
[0044] Fatigue testing: Cyclic loading to verify lifespan (e.g., performance degradation after 10^6 cycles).
[0045] Environmental testing: Durability under high and low temperature (-40℃~120℃), humidity, salt spray and other conditions.
[0046] In actual use, the upper connecting steel plate 1 is fixedly connected to the machine equipment, and the lower connecting steel plate 2 is fixedly connected to the base or ground to be fixed. When the machine equipment vibrates, the vibration is transmitted to the rubber shock absorber 3 through the upper connecting steel plate 1. The elastic damping effect of the rubber shock absorber 3 can effectively absorb and reduce the vibration. At the same time, the vibration detection element 5 and the weighing element 4 will detect and collect vibration information and machine equipment weight information. Based on the vibration information and machine weight, a vibration structure that can effectively reduce the vibration of the machine equipment, meets the load-bearing requirements, and has a sufficient service life is selected. Through the synergistic effect of the weighing element 4 and the vibration detection element 5, the weight and vibration of the equipment can be monitored in real time, abnormalities of the equipment can be detected in time, and operational safety can be improved.
[0047] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
