These vibrations not only affect the normal operation of the equipment, but also pose a potential threat to the surrounding environment and the safety of operators. Especially in the power, chemical, petroleum and other industries, these equipment are often used for large-scale fluid transportation, and the solution to their vibration problems is particularly urgent.
[0003] Traditional vibration reduction methods, such as dynamic balancing, axis alignment, and clearance elimination, can reduce vibration to a certain extent, but often require a large range of changes or adjustments to the equipment. Changes and adjustments have certain limitations and are difficult to operate for large and important equipment. Therefore, in order to more effectively control vibration, vibration reduction devices such as tuned mass dampers and vibration isolators are widely used. These devices can effectively isolate or absorb vibration, reduce the impact of vibration, consume vibration energy, and thus protect equipment from the impact of vibration.

[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0036] See also Figures 1 to 6 The fixing device for a horizontal pump unit provided in an embodiment of the utility model includes a support assembly 10 and a fixing assembly 20. The support assembly 10 includes a support frame 11 and a support base 12, and the support base 12 is arranged on the support frame 11; the fixing assembly 20 is arranged on the support base 12, and the fixing assembly 20 includes a fixing clamp 21 and a plurality of clamping members 22, the fixing clamp 21 extends in an annular shape, and the horizontal pump unit 100 can be passed through and clamped in the fixing clamp 21, and the clamping member 22 is detachably connected to the fixing clamp 21, and the plurality of clamping members 22 are arranged at intervals along the circumference of the fixing clamp 21, one side of the clamping member 22 abuts against the inner wall of the fixing clamp 21, and the other side of the clamping member 22 abuts against the horizontal pump unit 100.
[0037] The horizontal pump unit 100 is an existing mechanical device in the art, and its specific structure is not described here. It is understandable that in other embodiments, the horizontal pump unit 100 can also be a pipe body of any equipment such as a motor and a pipeline, or a column, etc. The shape, size, material, etc. of the horizontal pump unit 100 are not limited here.
[0038] In this embodiment, the horizontal pump unit 100 is placed horizontally. For the convenience of description in conjunction with the drawings, the directions below are described in accordance with the directions shown in the drawings, but are not limited thereto.
[0039] The stability and strength of the entire device are ensured by the cooperation of the support frame 11 and the support base 12. The support base 12 is arranged on the support frame 11, which not only provides a support effect, but also improves the resistance of the device to vibration and impact. The annular extension of the fixing clamp 21 enables the horizontal pump group 100 to be inserted and clamped inside the fixing clamp 21, which not only simplifies the installation process, but also ensures that the horizontal pump group 100 can be tightly fixed, thereby reducing the displacement or damage caused by equipment vibration. The clamping member 22 is detachably connected to the fixing clamp 21, so that the number and position of the clamping member 22 can be adjusted as needed during actual operation, and it has high flexibility, so that the fixing device can adapt to horizontal pump groups 100 of different diameters and materials. Multiple clamping members 22 are arranged at intervals along the circumference of the fixing clamp 21, ensuring uniform pressure distribution, thereby avoiding excessive compression or deformation of the horizontal pump group 100. One side of the clamping member 22 abuts against the inner wall of the fixing clamp 21 , and the other side abuts against the horizontal pump unit 100 , thereby being able to better resist external vibrations and improving the stability and safety of the entire horizontal pump unit 100 .
[0040] In order to improve the fit between the fixed clamp 21 and the clamp 22, the inner wall of the fixed clamp 21 is formed with a first conical surface 211, and the clamp 22 is formed with a second conical surface 221, and the first conical surface 211 and the second conical surface 221 can fit each other and the two are slidably connected. By forming the first conical surface 211 and the second conical surface 221 on the inner wall of the fixed clamp 21 and the clamp 22 respectively, and making the two conical surfaces fit each other, more precise contact can be achieved, and the contact mode of the conical surface can better ensure the close fit between the contact surfaces than the traditional plane or simple curved surface contact, thereby having better stability. The conical surface can generate more concentrated force at the contact point, which helps to improve the anti-seismic and vibration reduction performance. When external vibration acts on the horizontal pump unit 100, the contact between the first conical surface 211 and the second conical surface 221 can effectively disperse the force generated by the vibration, thereby protecting the horizontal pump unit 100 from damage. The sliding connection design between the first conical surface 211 and the second conical surface 221 allows fine-tuning during the installation process, so that the clamping member 22 can slide freely inside the fixing clamp 21 to the optimal position, which not only simplifies the installation process, but also allows the fixing device to be adaptively adjusted to adapt to horizontal pump groups 100 of different sizes or shapes, thereby increasing the flexibility of installation.
[0041] Since the radius and size of the horizontal pump unit 100 in the actual field conditions are different, in order to be applicable to horizontal pump units 100 of different sizes, the fixed clamp 21 includes a plurality of arc hoops, which are connected end to end in sequence, and the adjacent two arc hoops are detachably connected. Thus, the operator can increase or decrease the number of arc hoops according to the size of the specific horizontal pump unit 100, ensuring that the fixed clamp 21 can fit tightly to any size of pipe. The detachable connection between the adjacent two arc hoops makes the installation and adjustment process simpler and faster. When the horizontal pump unit 100 needs to be maintained or replaced, the arc hoops can be disassembled or reconfigured without disassembling the entire fixture as a whole, reducing downtime and maintenance costs.
[0042] Specifically, two arc hoops are provided, and the arc hoops are semicircular, and the two ends of the two arc hoops are buckled and bolted respectively. The two semicircular arc hoops can surround the horizontal pump group 100 to form a complete circular fixed structure. The symmetrical arrangement of the two semicircular arc hoops helps to evenly distribute the pressure and reduce the uneven load on the horizontal pump group 100, thereby improving the stability and reliability of the fixation. In this embodiment, the fixing clamp 21 uses an integral annular clamp, so as to have higher strength and facilitate processing and production. In other embodiments, three, four, etc. arc hoops can also be provided, which is not limited here. In addition, the two adjacent arc hoops are buckled and bolted respectively, which is convenient for disassembly and assembly and has higher stability. In other embodiments, the two adjacent arc hoops can also be snap-connected, latched, etc., which is not limited here.
[0043] See also Figure 3 In the actual operation process, the fixing device provided by this embodiment also needs to be installed and coordinated with other devices on site. Therefore, in order to facilitate the installation of the fixing device, a plurality of mounting holes 213 are provided on the fixing clamp 21, so as to provide a variety of options and positions for the installation process, so that the fixing device can be more easily aligned with other equipment or supporting structures on site. So that the fixing device can be flexibly used in a variety of different installation environments, adapt to different installation requirements and conditions, and have high adaptability. It is understandable that the shape, size, and dimensions of the mounting hole 213 are not limited here, and can be adaptively set according to the actual needs of the site. In addition, in other embodiments, the mounting hole 213 can also be set as a mounting groove, a mounting protrusion, etc., which are not limited here.
[0044] See also Figure 2 and Figure 4 , the clamping piece 22 is used to clamp the horizontal pump unit 100 and the fixed clamp 21. Specifically, four clamping pieces 22 are provided, and the four clamping pieces 22 are evenly spaced and arranged, and the clamping piece 22 is bolted to the fixed clamp 21. The four evenly spaced clamping pieces 22 can evenly apply pressure around the horizontal pump unit 100 to avoid damage to the horizontal pump unit 100 due to concentrated pressure. Each clamping piece 22 is firmly connected to the fixed clamp 21 by bolts, which not only has high stability, but also is easy to adjust and maintain. During the installation process, the bolts can be fine-tuned to adjust the position of the clamping piece 22 so as to better cooperate with the fixed clamp 21 and the horizontal pump unit 100. In other embodiments, the clamping piece 22 can also be provided with three, five, etc., which are not limited here.
[0045] See also Figure 2 , Figure 5 and Figure 6 Regarding the support assembly 10, in this embodiment, the support base 12 includes a support plate 121 and a clamping plate 122. The support plate 121 is arranged on both sides of the clamping plate 122. The clamping plate 122 and the support plate 121 are welded and connected to form an integral body. A positioning slot 1222 is provided on the clamping plate 122. The positioning slot 1222 extends in an arc shape. The inner diameter of the positioning slot 1222 is equal to the outer diameter of the fixing clamp 21. The fixing clamp 21 can be clamped in the positioning slot 1222. The integral molding of the support plate 121 and the clamping plate 122 has higher structural strength, reduces the number of components, and reduces the weaknesses that may occur due to seams or connecting parts, thereby improving the durability and stability of the overall device. The fixing clamp 21 can be clamped in the positioning slot 1222, which is convenient for operation and improves the stability of the fixing clamp 21 after installation.
[0046] Specifically, a fixing hole 212 is provided on the fixing clamp 21, and a connecting hole 1221 is provided on the clamping plate 122 at a position corresponding to the fixing hole 212, and the fixing hole 212 and the connecting hole 1221 are connected by bolts. By providing a fixing hole 212 on the fixing clamp 21, and providing a connecting hole 1221 at a corresponding position on the clamping plate 122, and then firmly connecting the clamping plate 122 and the fixing clamp 21 by bolts, the stability and vibration resistance of the device are enhanced. In addition, the design of the bolt connection simplifies the installation process and facilitates the operator to disassemble and assemble the fixing clamp 21 and the clamping plate 122. In other embodiments, the fixing clamp 21 and the clamping plate 122 can also be set to a snap connection or a pin connection, etc., which is not limited here.
[0047] In addition, in order to improve the stability of the fixing device, a vibration isolator 30 is provided between the support frame 11 and the support base 12. The main function of the vibration isolator 30 is to absorb and isolate vibration, reduce the transmission of vibration generated by the horizontal pump group 100 during operation to the supporting structure and the surrounding environment, thereby protecting the equipment and structure from vibration damage. It is understandable that the vibration isolator 30 is a commonly used mechanical device in the field, and its operating principle and specific structure are not described in detail here.
[0048] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
