Description

Technical Field

[0001] This utility model relates to the field of natural gas compressor technology, and in particular to a vibration damping mounting assembly for electrical components of a natural gas compressor. Background Technology

[0002] As the core power equipment for natural gas transportation, refueling, and liquefaction, natural gas compressors generate continuous and intense broadband mechanical vibrations during operation. These vibrations mainly originate from the reciprocating motion of the piston, the opening and closing of the valves, and the rotation of the motor, with complex excitation directions covering multiple dimensions, including vertical and horizontal. Electrical components installed on the compressor, such as PLC controllers, monitoring sensors, and terminal boxes, contain delicate electronic circuits and brittle solder joints, making them extremely sensitive to vibration. Prolonged exposure to multi-directional vibration environments can easily lead to fatigue fracture of the pins of these electrical components, cracking of solder joints, poor contact of connectors, and false alarms, seriously threatening the stable operation of the compressor and production safety.

[0003] Currently, the industry commonly uses traditional rubber damping pads or simple metal bracket structures for vibration damping protection of electrical components in natural gas compressors. Over-reliance on easily aging materials like rubber results in low reliability and short service life under harsh operating conditions. Furthermore, simple metal brackets cannot simultaneously isolate multidimensional vibrations from both vertical and horizontal directions, providing incomplete protection for electrical components and making them susceptible to damage from multidimensional vibrations. Utility Model Content

[0004] Therefore, it is necessary to provide a vibration damping mounting assembly for natural gas compressor electrical components, which addresses the problem that existing vibration damping mounting assemblies cannot simultaneously isolate multidimensional vibrations from both vertical and horizontal directions, resulting in incomplete protection of electrical components and making compressor electrical components susceptible to damage due to multidimensional vibrations.

[0005] A vibration damping mounting assembly for electrical components of a natural gas compressor includes: a mounting module and an electrical component box, wherein the mounting module includes a mounting frame and a partition, and the partition is fixedly disposed inside the mounting frame; A shock-absorbing module, comprising a spring, a connecting column, a ball joint module, and a shock absorber; The spring is disposed on the upper surface of the partition plate, the spring is sleeved on the outer arc surface of the connecting column, the electrical component box is disposed on the upper surface of the connecting column, the ball joint module is disposed on the lower surface of the connecting column, and the shock absorber is disposed below the ball joint module.

[0006] In one embodiment, the reed is configured as a cross-shaped piece, and the end of the reed is bolted to the upper surface of the partition via an extension plate.

[0007] In one embodiment, a snap ring is fixedly disposed inside the spring, and a snap groove corresponding to the snap ring is formed on the outer arc surface of the connecting post.

[0008] In one embodiment, the ball joint module includes a ball head and a ball seat, the ball head being fixedly disposed on the lower surface of the connecting column and the ball head being rotatably disposed inside the ball seat.

[0009] In one embodiment, mounting plates are fixedly provided on both sides of the shock absorber, the ball seat is fixedly provided on the upper surface of a set of mounting plates, and the shock absorber is provided at the bottom of the mounting frame through another set of mounting plates.

[0010] In one embodiment, a shield is bolted to the front of the mounting frame, and the electrical component box does not contact the mounting frame or the shield.

[0011] In one embodiment, a movable groove is formed through the upper surface of the partition, and neither the ball joint module nor the shock absorber contacts the movable groove.

[0012] In one embodiment, the shock absorber includes a shock-absorbing spring and a shock-absorbing damper, with the shock-absorbing spring sleeved on the outer arc surface of the shock-absorbing damper.

[0013] Beneficial effects 1. The aforementioned vibration damping mounting assembly for the electrical components of the natural gas compressor uses a cross spring to absorb horizontal vibrations from the X and Y axes through the bending deformation of its arm. The combination of the ball joint module and the shock absorber jointly bears the vertical vibration of the Z axis. The ball joint module converts the vertical force into a multi-directional micro-oscillation motion, avoiding rigid impact, while the shock absorber provides core buffering and damping. By setting up a multi-dimensional composite vibration damping module consisting of a cross spring, connecting column, ball joint module, and shock absorber, the problem that a single vibration damping element cannot effectively isolate multi-dimensional vibrations at the same time is avoided. This provides multi-dimensional vibration damping for the electrical components inside the electrical component box and extends its service life.

[0014] 2. The above-mentioned vibration damping mounting assembly for electrical components of the natural gas compressor uses mechanical metal components such as cross springs, ball heads, and ball seats in conjunction with shock absorbers to provide multi-dimensional vibration damping for the electrical component box. The use of metal components has excellent characteristics such as high temperature resistance, oil resistance, aging resistance, and long fatigue life, enabling stable operation in the harsh environment of the natural gas compressor and overcoming the defects of traditional all-rubber vibration damping pads that are prone to aging and rapid performance degradation.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a vibration damping mounting assembly for electrical components of a natural gas compressor.

[0020] In one embodiment, a vibration damping mounting assembly for electrical components of a natural gas compressor includes: a mounting module 100 and an electrical component box 300. The mounting module 100 includes a mounting frame 101 and a partition 102. A baffle 103 is bolted to the front side of the mounting frame 101, and the electrical component box 300 does not contact the mounting frame 101 and the baffle 103. In this embodiment, the mounting frame 101 serves as the load-bearing foundation for the entire assembly and is securely fixed to the body of the natural gas compressor through its external mounting holes. The electrical component box 300 is connected to the compressor via a flexible connecting cable. The partition 102 divides the interior of the mounting frame 101 into upper and lower sections; the shield 103 provides dust protection, and the electrical component box 300 does not have rigid contact with the mounting frame 101 or the shield 103, forming a floating mounting system. This cuts off the path of vibration directly transmitted through the side wall of the box, ensuring a shock absorption effect.

[0021] like Figure 2 and Figure 3 As shown, the partition 102 is fixedly installed inside the mounting frame 101; the shock absorption module 200 includes a spring 201, a connecting column 202, a ball joint module, and a shock absorber 206; the spring 201 is disposed on the upper surface of the partition 102 and sleeved on the outer arc surface of the connecting column 202; the electrical component box 300 is disposed on the upper surface of the connecting column 202; the ball joint module is disposed on the lower surface of the connecting column 202; and the shock absorber 206 is disposed below the ball joint module. In this embodiment, the weight of the electrical component box 300 and its internal components is transmitted through the connecting column 202. Horizontal vibrations are first absorbed and isolated by the bending deformation of the cross spring 201, preventing them from being transmitted upwards. Vertical vibrations are transmitted downwards through the connecting column 202 and guided to the shock absorber 206 via the ball joint module, where the shock absorber 206 provides the main buffering and energy dissipation. This hierarchical processing ensures that the device can efficiently cope with the complex combined vibrations of the compressor.

[0022] like Figure 3 and Figure 5 As shown, the spring 201 is configured as a cross-shaped piece, and the end of the spring 201 is bolted to the upper surface of the partition 102 through the extension plate 208; a snap ring 209 is fixedly provided inside the spring 201, and a snap groove 210 corresponding to the snap ring 209 is opened on the outer arc surface of the connecting post 202. In this embodiment, the extension plate 208 provides a stable and reliable mounting point for the spring 201; the cross-shaped spring 201 provides isotropic stiffness on the horizontal plane, which can uniformly resist horizontal vibrations from different directions. The engagement of the snap ring 209 and the snap groove 210 ensures that the spring 201 and the connecting post 202 move synchronously in the horizontal direction, while allowing the connecting post 202 a certain degree of freedom of movement in the vertical direction.

[0023] like Figure 3As shown, the ball joint module includes a ball head 203 and a ball seat 204. The ball head 203 is fixedly installed on the lower surface of the connecting column 202 and is rotatably installed inside the ball seat 204. A movable groove 207 is provided through the upper surface of the partition plate 102. Neither the ball joint module nor the shock absorber 206 contacts the movable groove 207. In this embodiment, the ball joint 203 and the ball seat 204 form a spherical joint, allowing the vertical force from the connecting column 202 to be transmitted to the shock absorber 206 in a universal manner, avoiding the formation of harmful bending moments and protecting the shock absorber 206 and the connecting column 202. When subjected to non-purely vertical vibrations or impacts, the ball joint module allows the connecting column 202 to produce slight multi-angle yaw. This yaw action will cause a slight warping deformation of the upper cross spring 201, thereby further dissipating vibration energy and forming a secondary buffer. The movable groove 207 provides the necessary space for the movement of the connecting column 202 and the ball joint module, ensuring that the entire assembly will not interfere with the partition 102 during dynamic processes, guaranteeing smooth movement and the reliability of the device.

[0024] like Figure 3 As shown, mounting plates 205 are fixedly installed on both sides of the shock absorber 206, and ball seat 204 is fixedly installed on the upper surface of a set of mounting plates 205. The shock absorber 206 is installed at the bottom of the mounting frame 101 through another set of mounting plates 205. The shock absorber 206 includes a shock-absorbing spring and a shock-absorbing damper, and the shock-absorbing spring is sleeved on the outer arc surface of the shock-absorbing damper. In this embodiment, the mounting plate 205 provides an interface to facilitate the connection and installation between the ball joint module and the shock absorber 206, as well as between the shock absorber 206 and the mounting frame 101. The shock absorber 206 adopts an integrated structure of shock-absorbing spring and shock-absorbing damper to provide vertical shock absorption for the electrical component box 300. The shock-absorbing spring mainly provides elastic support and absorbs vibration energy, while the shock-absorbing damper is used to quickly suppress the reciprocating oscillation of the spring, converting mechanical energy into heat energy for dissipation, preventing the electrical component box 300 from continuously shaking after shock absorption, thereby quickly restoring stability.

[0025] The vibration damping module 200 will not have any adverse effect on the normal operation of the electrical components inside the electrical component box 300. Its multi-dimensional vibration damping characteristics solve the problem of compressor vibration damaging components.

[0026] Working Principle: When the compressor is running, the multidimensional vibrations it generates are transmitted to the mounting frame 101. For horizontal vibrations, the movement of the mounting frame 101 attempts to drive the end of the cross spring 201 through the partition 102 and the extension plate 208. The center of the spring 201 is fixed to the connecting post 202 through the snap ring 209. Therefore, the arm of the spring 201 will bend and deform, thereby absorbing and isolating the horizontal vibrations and preventing them from being transmitted upward to the electrical component box 300. For vertical vibrations, they are transmitted downward through the connecting post 202. First, the ball head 203 is driven to move slightly within the ball seat 204, directing the force to the shock absorber 206. The spring of the shock absorber 206 is compressed or stretched, absorbing the main energy, while the internal damper suppresses rebound oscillations. During this process, the movement of the ball joint module will cause the connecting post 202 to deflect slightly, which in turn causes the cross spring 201 to warp, as a supplementary mechanism for vertical vibration damping. Most of the vibration energy is effectively isolated and dissipated by the vibration damping module 200, thus providing a stable operating environment for the electrical component box 300.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
