Description

Technical Field

[0001] This utility model belongs to the field of industrial variable frequency fan technology, specifically relating to an installation and assembly structure for an industrial variable frequency fan. Background Technology

[0002] Industrial variable frequency fans, with their flexible speed adjustment and energy-efficient characteristics, have become core equipment in industrial scenarios such as workshop ventilation, equipment heat dissipation, and warehouse cooling. As a key component connecting the fan body to the mounting base (wall, ceiling, etc.), its installation and mating structure directly determines the equipment's operational stability, service life, and ease of maintenance. Therefore, it is necessary to design an industrial variable frequency fan installation and mating structure.

[0003] Traditional industrial fan installations often use rigid connection methods (such as direct welding of brackets or bolt fixing) without an effective buffer structure. The high-frequency vibration generated by the variable frequency motor during operation is directly transmitted to the wall or ceiling through the installation structure, causing resonance of the mounting base and resulting in noise pollution. Furthermore, the continuous transmission of vibration can lead to loose mounting bolts, fatigue deformation of the bracket, and in severe cases, even the risk of the fan falling. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed installation and assembly structure for industrial variable frequency fans in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An industrial variable frequency fan mounting structure includes a power mechanism, a fan blade fixedly mounted on the output end at the bottom of the power mechanism, a mounting rod threadedly fixed to the top of the power mechanism, a connecting component fixed to the top of the mounting rod, a buffer component placed above the top of the connecting component, and mounting components slidably connected to both sides of the buffer component, with the two mounting components cooperating.

[0007] As a further optimization of this utility model, the connecting assembly includes a fixing plate welded to the top of the mounting rod, and chains are fixed at the four corners of the top of the fixing plate.

[0008] As a further optimization of this utility model, the buffer assembly includes a connecting plate placed above the top of the fixed plate and fixedly connected to the chain. A limiting rod that slides through the connecting plate is fixedly installed at the middle position of the top of the fixed plate. A spring is fixedly sleeved on the top of the outer side of the limiting rod.

[0009] As a further optimization of this utility model, both sides inside the connecting plate are slidably fitted with U-shaped buffer blocks that fit against the outside of the limiting rod, and the U-shaped buffer blocks are placed below and fit against the spring one. The top and bottom of the two U-shaped buffer blocks on the opposite side are slidably fitted with guide rod one that is fixedly connected to the connecting plate, and the opposite sides of the two guide rods one on the same side are fitted with spring two that is fixed to the U-shaped buffer blocks.

[0010] As a further optimization of this utility model, the installation assembly includes two guide rods two fixedly installed on both sides of the connecting plate. An L-shaped fixing rod placed above the connecting plate is slidably fitted on the outside of each of the two guide rods two. A C-shaped mounting block is fixedly installed on the side of the top of each of the two L-shaped fixing rods that is close to each other, and the two C-shaped mounting blocks cooperate with each other.

[0011] As a further optimization of this utility model, a through-hole that cooperates with the limiting rod is provided in the middle position inside the connecting plate. Both sides inside the through-hole are fitted with U-shaped buffer blocks that fit against the outside of the limiting rod. Guide grooves that cooperate with the U-shaped buffer blocks are symmetrically provided in the middle positions of the top and bottom of the connecting plate.

[0012] The beneficial effects of this utility model are as follows: Through the structural design of the buffer component, this utility model can achieve multi-level buffering function, significantly reducing vibration and noise. Through this structural design, it can achieve longitudinal and lateral buffering functions, effectively avoiding vibration generated on the mounting base when the industrial variable frequency fan is working, and effectively avoiding wall cracking or ceiling loosening caused by long-term vibration. At the same time, in conjunction with the structural design of the mounting component, it can achieve flexible installation and adjustment function, adapting to the installation needs of multiple scenarios. By adjusting the lateral spacing, it can adapt to mounting bases of different widths. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 , Figure 2 As shown, an industrial variable frequency fan mounting structure includes a power mechanism 1, fan blades 2, mounting rod 3, buffer assembly 4, mounting assembly 5, and connecting assembly 6. The power mechanism 1 drives the fan blades 2 to rotate and generate airflow. The fan blades 2 are connected to the connecting assembly 6 via the mounting rod 3. The connecting assembly 6 transfers the load of the power mechanism to the buffer assembly 4. The buffer assembly 4 dampens vibration through an elastic structure. The mounting assemblies 5 on both sides of the buffer assembly 4 are fixed to the wall or ceiling to form a complete mounting support system. The power mechanism 1 includes a mounting housing and an industrial variable frequency motor. The industrial variable frequency motor is fixedly installed inside the mounting housing. The bottom output shaft of the motor is fixedly mounted to the fan blades 2 via a flat key. The top of the mounting housing has four threaded mounting holes. The mounting rod 3 is a seamless steel pipe. The bottom of the motor is fixedly threaded to the top of the power mechanism 1 via bolts, and the top is fixedly connected to the connecting assembly 6 to form a vertical load-bearing structure.

[0022] like Figure 2 , Figure 4 As shown, the connecting component 6 serves as a transition structure between the power mechanism and the buffer component. It includes a fixed plate 600 that is fixedly connected to the top of the mounting rod 3. Four through holes are evenly distributed at the four corners of the fixed plate 600. A chain 601 (stainless steel chain) is fixedly installed inside the four through holes. The other end is bolted to the bottom of the connecting plate 400 of the buffer component 4 to form a flexible auxiliary load-bearing structure, thereby preventing the mounting rod 3 from being overloaded by a single point of force.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the buffer assembly 4 is the core component for reducing fan vibration. It includes a connecting plate 400, a U-shaped buffer block 401, a first spring 402, a limiting rod 403, a first guide rod 404, and a second spring 405. The connecting plate 400 is positioned above the fixed plate 600 and its bottom is fixed to the chain 601. An opening is provided in the center of the connecting plate 400, with arc-shaped wear-resistant rubber pads fixedly installed at both ends inside the opening to buffer the vibration force in the forward and backward directions. The bottom of the limiting rod 403 is vertically welded to the center of the top of the fixed plate 600, and its top slides through the opening of the connecting plate 400, providing longitudinal guidance. The opening is connected to... The limiting rod 403 has a certain gap to facilitate the buffering function when the limiting rod shakes later. A limiting block is fixedly installed on the top of the limiting rod 403. Spring 402 is a cylindrical compression spring, which is fixedly sleeved on the top of the outer side of the limiting rod 403 through a shoulder and fixedly connected to the limiting block. Sliding grooves are opened on the top of both sides of the limiting rod 403. A slider is slidably installed in the bottom of the inner side of each of the two sliding grooves. A collar sleeved on the outside of the limiting rod 403 and fixedly connected to the bottom of spring 402 is installed on the side of the two sliders that are far apart from each other. The U-shaped buffer block 401 consists of two wear-resistant rubber blocks with the opening facing the connecting plate 400 and the inner side connected to the limiting rod. The outer wall of the positioning rod 403 is fitted, and the U-shaped buffer block 401 is placed inside the opening and slides and engages with the connecting plate 400. There is a certain gap between the inner side of the opening of the connecting plate 400 and the U-shaped buffer block 401 to facilitate the movement of the U-shaped buffer block 401 for buffering. Guide grooves are provided on both the top and bottom sides of the connecting plate 400. Guide sliders fixed to the U-shaped buffer block 401 are slidably installed inside the two guide grooves on the same side to limit the displacement direction of the U-shaped buffer block 401. The top of the U-shaped buffer block 401 abuts against the bottom of the spring 402 to absorb longitudinal vibration. The kinetic energy is generated by two groups of guide rods 404 symmetrically fixed on the top and bottom sides of the connecting plate 400, with each group distributed vertically in parallel. The U-shaped buffer block 401 has a sliding hole on the far side, which slides and engages with the guide rod 404. There are four springs 405, which are respectively fitted on the far outer ends of the two guide rods 404 on the same side. One end is fixed to the side of the U-shaped buffer block 401, and the other end is fixed to the top of the connecting plate 400. They absorb lateral vibration through elastic deformation. Fixing blocks are fixedly installed on the edges of the top and bottom sides of the connecting plate 400. The fixing blocks are fixedly connected to the guide rod 404 and the spring 405.

[0024] like Figure 3 , Figure 4As shown, the installation component 5 connects the equipment to the installation base, including an L-shaped fixing rod 500, a C-shaped mounting block 501, and a second guide rod 502. The second guide rod 502 is horizontally welded to both sides of the connecting plate 400, with its axis parallel to the long side of the connecting plate. The L-shaped fixing rod 500 has two vertical sections with sliding holes, which slide and fit with the second guide rod 502, allowing for horizontal adjustment of its position along the guide rod. The top of the inner side of both guide rods 502 is welded with inclined reinforcing rods to improve the load-bearing capacity of the L-shaped fixing rod 500. The C-shaped mounting block 501 consists of two bent steel plates welded and fixed to the top of the two L-shaped fixing rods 500 on the side where they are close to each other. The opening has a waist-shaped mounting hole. The two C-shaped mounting blocks fit symmetrically and are fixed to the wall or ceiling joists by expansion bolts.

[0025] It should be noted that in the installation and assembly structure of this industrial variable frequency fan, the fan blade 2 is first fixed to the output end of the power mechanism 1. The bottom of the mounting rod 3 is threadedly connected to the top of the power mechanism. The fixing plate 600 is welded to the top of the mounting rod 3. The two ends of the chain 601 are respectively connected to the fixing plate 600 and the connecting plate 400. The limiting rod 403 passes through the opening of the connecting plate 400. The first spring 402 is fitted onto the top of the limiting rod. The U-shaped buffer block 401, the first guide rod 404, and the second spring 405 are assembled into the inside of the connecting plate 400 according to their positions. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, guide rod 502 is welded to both sides of connecting plate 400, and L-shaped fixing rod 500 is fitted together to fix C-shaped mounting block 501, completing the overall assembly;

[0026] Longitudinal vibration attenuation: The longitudinal vibration of the fan during operation is transmitted to the limit rod 403 through the mounting rod 3, which pushes the connecting plate 400 to move up and down. The spring 402 is compressed or extended, converting kinetic energy into elastic potential energy and reducing the transmission of vibration to the mounting base. Lateral vibration attenuation: Lateral vibration causes the limit rod 403 to squeeze the U-shaped buffer blocks 401 on both sides. The buffer blocks slide along the guide groove and compress the spring 405. The lateral energy is absorbed by the combined action of rubber deformation and spring elasticity, reducing the risk of resonance.

[0027] By sliding the L-shaped fixing rod 500 along the guide rod 502, the distance between the two C-shaped mounting blocks 501 can be adjusted to accommodate mounting bases of different widths. The slotted hole of the C-shaped mounting block 501 allows for installation position deviation compensation of ±10mm, reducing the requirements for installation point accuracy.

[0028] This embodiment significantly reduces fan vibration and noise through a multi-dimensional buffer structure, while also providing adjustable installation position. It solves the problems of poor installation adaptability and significant vibration transmission of traditional industrial fans, thereby improving equipment operation stability and service life.

[0029] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
