Description

[0001] The invention relates to the field of shock absorbing devices, in particular to a method for shock absorbing and limiting large equipment. Background Art

[0002] In many areas of modern industry and life, the importance of shock absorption equipment is becoming increasingly prominent. With the rapid development of science and technology, various types of mechanical equipment, transportation vehicles and building structures are constantly evolving towards large-scale, high-speed and complex. In industry, large precision machine tools, high-speed motor equipment and automated production lines, etc., the vibrations they generate during operation will not only affect their own working accuracy and stability, but may also accelerate the wear of equipment parts, shorten the service life of equipment, and even cause failures that lead to production interruptions, causing huge economic losses.

[0003] At present, large equipment will generate vibrations during operation. If these vibrations are not controlled, they may cause damage to the equipment itself and its surrounding structures. Therefore, shock absorbers are usually installed at the bottom of the refrigeration unit to reduce the transmission of vibrations. However, existing shock absorbers can often only provide shock absorption effects in a single direction and cannot limit the displacement of large equipment, which to a certain extent affects the stability and safety of equipment operation.

[0013] By adopting the above technical solution, the energy generated by the vibration during the operation of large equipment can be dispersed and absorbed.

[0014] Furthermore, the connecting frame as a whole is composed of two groups of L-shaped plates and a group of cross plates.

The cross plates are installed at the bottom of the two groups of L-shaped plates, and the cross plates are connected to the bottom angle plates.

[0015] By adopting the above technical solution, the shock absorber is not placed directly at the bottom of the large equipment, but is placed on both sides of the large equipment, ensuring that the shock absorber has the ability to horizontally limit the large equipment.

[0016] Furthermore, the distance from the top of the connecting frame to the bottom thereof is greater than half of the distance between the top of the fixed base and the base of the shock absorbing device.

[0017] By adopting the above technical solution, the center of gravity of large equipment can be effectively lowered, and the stability of the horizontal position of large equipment can be further improved.

[0018] Furthermore, the shock absorbers are symmetrically installed in multiple groups on the top of the shock absorbing equipment base, and the setting positions and numbers of the shock absorbers correspond to the bottom angle plates of the large equipment.

[0019] By adopting the above technical solution, it is ensured that when large equipment is installed, there will be corresponding shock absorbers to restrict the large equipment.

[0029] S5: Connect the connecting frame to the bottom angle plate by bolts to ensure the stability of the connecting frame after being connected to the bottom angle plate.

[0030] In summary, the present invention mainly has the following beneficial effects:

[0031] 1. The present invention can effectively absorb and disperse the vibration energy generated by the operation of large equipment through the coordinated work of the shock-absorbing spring and the rubber shock-absorbing pad in the adjustable shock-absorbing unit. The shock-absorbing spring converts the vibration into elastic potential energy through elastic deformation, and the rubber shock-absorbing pad further buffers and dissipates the vibration by using its material properties. The combination of the two greatly reduces the impact of vibration on the equipment and the surrounding environment. For example, in industrial production, for high-precision processing equipment, effective shock absorption can improve the processing accuracy and reduce the defective rate of products caused by vibration; for large ventilation equipment in buildings, shock absorption can reduce the damage to the building structure caused by vibration and extend the service life of the building.

[0032] 2. The present invention realizes effective limitation of large equipment by providing a connection between the connecting frame and the bottom angle plate and a structural design on the fixed base (such as an adjustment groove and a rubber pad, etc.). During the operation of the equipment, the equipment is prevented from excessively displacing in the horizontal or vertical direction due to vibration or other external forces, thereby ensuring that the equipment is always in a safe and stable operating position. This is especially important for some equipment with high requirements for position accuracy, and can avoid production failures and safety accidents caused by equipment displacement. At the same time, the shock absorber is not placed directly at the bottom of the large equipment, but on both sides of the large equipment, and is connected to the bottom angle plate of the large equipment through the connecting frame, thereby reducing the distance between the large equipment and the top of the base of the shock-absorbing equipment, effectively lowering the center of gravity of the large equipment, and further improving the stability of the horizontal position of the large equipment.

[0033] 3. The present invention provides an elastic adjustment stud so that the shock absorber can be adjusted according to the weight, vibration frequency and other characteristics of different large-scale equipment. The supporting force of the elastic adjustment stud on the pressure plate is changed by adjusting the nut, thereby optimizing the working state of the shock-absorbing spring and the rubber shock-absorbing pad to adapt to various complex working conditions. For example, for refrigeration units of different models and specifications, the shock absorber can be adjusted according to their actual operating parameters to achieve the best shock absorption and limiting effect, thereby improving the versatility and practicality of the method on different equipment.

DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The present invention aims to provide a method for effectively reducing shock and limiting position of large equipment, so as to solve the problems of single shock absorbing direction and inability to limit displacement existing in the application of existing shock absorbers in large equipment, and ensure the stability and safety of large equipment operation.

[0042] The following describes an embodiment of the present invention based on its overall structure.

[0043] This embodiment provides a method for shock absorption and position limiting of large equipment, such as Figure 1 - Figure 5 As shown, the method mainly involves a shock absorbing device base 1, a large device 2 and a shock absorber 3.

[0044] Among them, a bottom angle plate 21 is installed at the bottom of the large equipment 2, and the bottom angle plate 21 is connected to the shock absorber 3, so that the large equipment 2 is installed on the shock absorbing equipment base 1 through the shock absorber 3. The shock absorber 3 includes a fixed base 31, a pressure plate 36, a connecting frame 37 and an adjustable shock absorbing unit. The pressure plate 36 is installed on the top of the fixed base 31. The connecting frame 37 on the top of the pressure plate 36 is connected to the bottom angle plate 21 and has an L-shaped cross-section. The bottom angle plate 21 is located at the bottom of the outer end of the connecting frame 37. This structural design enables the weight and vibration of the large equipment 2 to be transmitted to the pressure plate 36 through the connecting frame 37, and then further transmitted to the adjustable shock absorbing unit for shock absorption.

[0045] The adjustable shock absorbing unit in this embodiment is installed inside the fixed base 31, and its top is connected to the bottom of the pressure plate 36. It includes components such as an elastic force adjustment stud 32, a shock absorbing spring 33 and a rubber shock absorbing pad 35. The elastic force adjustment stud 32 is fixedly installed in the fixed base 31, and its top is slidably connected to the pressure plate 36 and is equipped with a nut that is in contact with the top of the pressure plate 36. The shock absorbing spring 33 is fixedly installed in the bottom of the fixed base 31, and its top is connected to an upper fixed plate 34 slidably installed on the elastic force adjustment stud 32. The rubber shock absorbing pad 35 is slidably installed on the outer wall of the elastic force adjustment stud 32 and is in contact with the top of the upper fixed plate 34 and the bottom of the fixed base 31. When vibration is generated during equipment operation, the shock absorbing spring 33 absorbs vibration energy through its own elastic deformation, and the rubber shock absorbing pad 35 further disperses and offsets the vibration. The elastic force adjustment stud 32 can change the supporting force on the pressure plate 36 by adjusting the nut, thereby realizing the adjustment of the shock absorbing effect to meet the needs of different equipment and working conditions.

[0046] The connecting frame 37 in the present embodiment is composed of two groups of L-shaped plates and a group of cross plates. The two groups of L-shaped plates are connected to the top of the pressure plate 36 and the ends located on the outside of the fixed base 31 are longitudinally arranged plates. The cross plate is installed at the bottom of the two groups of L-shaped plates and connected to the bottom angle plate 21. This structure enables the connecting frame 37 to stably connect the large equipment 2 and the shock absorber 3, and can effectively transmit force and displacement during the shock absorption process. The distance from the top to the bottom of the connecting frame 37 is greater than half of the distance between the top of the fixed base 31 and the shock absorption device base 1, which ensures the reliability and stability of the connection, and also provides a reasonable spatial layout for shock absorption and limiting. At the same time, the shock absorber 3 is not placed directly at the bottom of the large equipment 2, but on both sides of the large equipment 2, and is connected to the bottom angle plate 21 of the large equipment 2 through the connecting frame 37, thereby reducing the distance between the large equipment 2 and the top of the shock absorption device base 1, effectively reducing the center of gravity of the large equipment 2, and further improving the stability of the horizontal position of the large equipment 2.

[0047] Specifically, the shock absorbers 3 in this embodiment are symmetrically installed in multiple groups on the top of the shock absorbing equipment base 1, and their setting positions and numbers correspond to the bottom angle plates 21 of the large equipment 2. This layout ensures that the vibration of the large equipment 2 in all directions can be effectively suppressed, and the evenly distributed shock absorbers 3 can better withstand the weight of the equipment and vibration impact. There are multiple groups of elastic adjustment studs 32 installed at equal intervals in the fixed base 31, and a group of shock absorbing springs 33 are sleeved on the outer wall of each group and staggered with the connecting frame 37. This design makes the shock absorbing force distribution more uniform, avoids local uneven force, and improves the overall shock absorption effect. Adjustment grooves 38 corresponding to the connecting frame 37 are opened on the outer walls on both sides of the fixed base 31, and rubber pads 39 are installed on the inner wall. The adjustment grooves 38 facilitate the installation and adjustment of the connecting frame 37, and the rubber pads 39 play a buffering and protective role to prevent the connecting frame 37 from directly colliding with the fixed base 31 to produce wear and noise.

[0048] The present invention provides a method for shock absorption and position limiting of large equipment, the process of which includes the following steps:

[0049] First, prepare for equipment installation; select appropriate specifications and quantities of shock absorbers 3 and corresponding shock absorbing equipment bases 1 according to the size and weight of the large equipment 2; ensure that the shock absorbing equipment bases 1 are installed on a solid and flat foundation to provide stable support;

[0050] Next, use the lifting equipment to slowly transport the large equipment 2 to the installation position on the top of the shock-absorbing equipment base 1 to ensure that the equipment is accurately positioned; then, install and preliminarily adjust the shock absorber; install the shock absorber 3 on the top of the shock-absorbing equipment base 1 according to the design requirements; determine the installation position of the shock absorber 3 according to the position of the bottom angle plate 21 of the large equipment 2 to ensure that the two correspond; during the installation process, check whether the connection between the fixed base 31 and the shock-absorbing equipment base 1 is firm, whether the adjustment groove 38 is unobstructed, and whether the rubber pad 39 is installed in place; after the installation is completed, preliminarily adjust the nut on the elastic adjustment stud 32 to make the pressure plate 36 in an appropriate initial position to prepare for the subsequent connection of the large equipment 2;

[0051] Then, the large equipment 2 is lifted upwards so that the top surface of the bottom angle plate 21 is in contact with the bottom of the connecting frame 37 of the shock absorber 3; the connecting frame 37 is firmly connected to the bottom angle plate 21 by bolts to ensure the reliability and stability of the connection; during the connection process, the fit between the connecting frame 37 and the bottom angle plate 21 is checked to ensure that the force can be effectively transmitted;

[0052] Then, the shock absorption effect is finally adjusted; after the equipment is connected, the shock absorber 3 is finally adjusted according to the actual operation of the large equipment 2; the nut on the elastic force adjustment stud 32 is turned by a tool to accurately adjust the position of the pressure plate 36, thereby changing the compression degree of the shock absorbing spring 33 and the stress state of the rubber shock absorbing pad 35 to achieve the best shock absorption effect; during the adjustment process, a vibration test instrument can be used to detect the vibration of the equipment, and fine-tuning can be performed according to parameters such as vibration amplitude and frequency until the stability and comfort requirements of the equipment operation are met;

[0053] Finally, after the large equipment 2 is officially put into operation, the operating status and shock absorption effect of the equipment are continuously monitored; the working conditions of the various components of the shock absorber 3 are regularly checked, including whether the shock absorbing spring 33 is deformed or damaged, whether the rubber shock absorbing pad 35 is aged, whether the connection between the connecting frame 37 and the bottom angle plate 21 is loose, etc.; at the same time, pay attention to the vibration of the equipment. If abnormal vibration increases or abnormal noise occurs, stop the equipment in time for inspection and adjust or repair the shock absorber 3.

[0054] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
