Description

Technical Field

[0001] This utility model relates to the field of vibration motor equipment technology, and specifically to a reinforcement mechanism for an explosion-proof vibration motor. Background Technology

[0002] In industrial production and many fields requiring vibration drive, vibratory motors are key drive devices, and their performance and safety directly affect the stability and safety of the entire production process. Existing vibratory motors, during operation, are prone to generating significant vibrational impact forces due to their continuous vibration and interaction with the machine body they are installed on. This impact force not only subjects the motor's components, such as the stator, rotor, and vibrating head, to considerable stress, leading to accelerated wear and shortened service life, but can also affect the stability of the connection between the vibratory motor and the machine body, causing loosening and displacement, thus affecting the normal operation of the entire vibration system. Furthermore, in certain industrial environments, such as those containing flammable and explosive gases or dust, sparks generated by the vibratory motor during operation due to internal faults or component friction can easily trigger explosions, posing a significant threat to production safety and the lives and property of personnel. Currently, some vibratory motors on the market lack sufficient explosion-proof performance and effective explosion-proof protection measures, failing to meet the safety requirements of these special environments. Therefore, developing a vibratory motor reinforcement mechanism with good reinforcement effects and explosion-proof functions is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a technical solution for a reinforcement mechanism of an explosion-proof vibratory motor, thereby addressing the shortcomings mentioned in the background art.

[0025] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principles of the embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific parts in particular drawings may be exaggerated to illustrate relevant details or structures of the embodiments of this disclosure. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0026] Example 1: In practical applications, the reinforcement mechanism of this explosion-proof vibration motor first involves the installation of the basic structure. The explosion-proof vibration motor 1 is placed in a suitable position on the machine body requiring vibration, and the installation reference is determined based on the structural characteristics of the machine body. For the explosion-proof vibration motor 1, the base 14, which is fixedly connected to the bottom surface of its stator 11, contacts the machine body. Bolts 15, which are inserted through the four corners of the base 14, are used to lock the base 14 to the machine body. Using tools such as wrenches, the operator sequentially passes the bolts 15 through the through holes at the four corners of the base 14 and the corresponding threaded holes on the machine body, and gradually tightens them, ensuring that the explosion-proof vibration motor 1 is securely installed on the machine body.

[0027] Next, the reinforcement structure 3 is installed, which is set at both ends of the explosion-proof vibration motor 1. The reinforcement cover 31 of the reinforcement structure 3 is annular and can cover both ends of the explosion-proof vibration motor 1. 8-10 rubber buffer sheets 34 are embedded in a circular array on the inner wall of the reinforcement cover 31. During the embedding process, the rubber buffer sheets 34 are first placed into the arc-shaped grooves 36 opened on the inner wall of the reinforcement cover 31. The arc-shaped grooves 36 are arranged in a circular array with the central axis of the reinforcement cover 31 as the base point to ensure accurate installation of the rubber buffer sheets 34. The inner end face of the rubber buffer sheet 34 protrudes 3mm-5mm from the inside of the arc-shaped groove 36. After installation, the inner end face of the rubber buffer sheet 34 contacts the outer surface of the vibration head 12, playing a role in buffering and shock absorption. Two connectors 35 are fixed on the front and rear side walls of the outer ring of the reinforcement cover 31. An L-shaped connecting rod 33 is connected to the bottom of each connector 35. During connection, one end of the L-shaped connecting rod 33 is mated with the connector 35. Both the connector 35 and the L-shaped connecting rod 33 have threaded holes at their mating positions. A screw 32 is screwed into the threaded holes to secure the connector 35 and the L-shaped connecting rod 33 together. The end of the L-shaped connecting rod 33 furthest from the connector 35 is then fixedly connected to the machine body that requires vibration. This can be achieved by pre-drilling holes in the machine body, inserting the end of the L-shaped connecting rod 33 into the holes, and then securing it with bolts or welding to ensure the reinforcing structure 3 is firmly connected to the machine body.

[0028] Finally, install the explosion-proof mesh 2. The left and right ends of the explosion-proof mesh 2 are secured to the top surface of the reinforcing cover 31 with screws. The operator covers the explosion-proof mesh 2 over the side of the explosion-proof vibration motor 1 and the reinforcing structure 3 away from the machine body that needs vibration. Screws are then passed through the through holes at the ends of the explosion-proof mesh 2 and the threaded holes on the top surface of the reinforcing cover 31, and tightened to ensure the explosion-proof mesh 2 completely covers the explosion-proof vibration motor 1 and the reinforcing structure 3, providing explosion protection.

[0029] Example 2: In some special application scenarios, higher requirements are placed on the vibration damping performance of the explosion-proof vibration motor. The number and size of the rubber buffer sheets 34 can be adjusted according to the actual situation. If enhanced vibration damping is required, the number of rubber buffer sheets 34 can be increased to 10. During installation, following the method in Example 1, the 10 rubber buffer sheets 34 are respectively placed into the 10 arc-shaped grooves 36 opened on the inner wall of the reinforced cover 31. At this time, due to the increase in the number of rubber buffer sheets 34, the size of the rubber buffer sheets 34 can be appropriately adjusted so that their inner end faces protrude 4mm-5mm from the inside of the arc-shaped grooves 36, thereby increasing the contact area and buffering force with the outer surface of the vibrating head 12. Conversely, if the application scenario has strict space requirements and the volume of the reinforced structure needs to be reduced, the number of rubber buffer sheets 34 can be reduced to 8. During installation, the 8 rubber buffer sheets 34 are placed into the corresponding arc-shaped grooves 36, with the inner end faces of the rubber buffer sheets 34 protruding 3mm-4mm from the inside of the arc-shaped grooves 36, ensuring a certain vibration damping performance while meeting space requirements. The installation steps for the remaining reinforcement structure 3, such as the connection between the reinforcement cover 31 and the connector 35 and the L-shaped connecting rod 33, and the installation of the explosion-proof mesh 2, are the same as in Embodiment 1.

[0030] Example 3: In some special machine body structures, the connection method between the reinforcing structure 3 and the machine body needs to be adjusted accordingly. When the side space of the machine body is limited and it is not possible to directly use bolts to fix the end of the L-shaped connecting rod 33 away from the joint 35, welding can be used for fixing. After completing the installation of other components of the reinforcing structure 3, adjust the end of the L-shaped connecting rod 33 away from the joint 35 to a suitable welding position with the side of the machine body, and use electric welding equipment to weld the end of the L-shaped connecting rod 33 firmly to the side of the machine body to ensure that the reinforcing structure 3 is stably connected to the machine body. If the machine body has a special slot structure, the end of the L-shaped connecting rod 33 away from the joint 35 can be designed to match the shape of the slot. During installation, insert the end of the L-shaped connecting rod 33 directly into the slot on the machine body, and then use buckles or other fixing devices to fix the end of the L-shaped connecting rod 33 in the slot to prevent it from loosening. After the reinforcement structure 3 is fixed to the machine body, the explosion-proof mesh 2 is installed according to the method in Example 1 to complete the installation of the reinforcement mechanism of the entire explosion-proof vibrating motor.

[0031] The workflow of this technical solution is described in detail below:

[0032] First, prepare for the overall installation of the reinforcement mechanism of the explosion-proof vibration motor. Move the explosion-proof vibration motor 1 to a suitable position on the machine body that needs vibration. Determine the installation reference based on the machine body's structure and installation requirements. Place the base 14, which is fixedly connected to the bottom surface of the stator 11 of the explosion-proof vibration motor 1, onto the machine body. Bolts 15, which are installed at the four corners of the base 14, pass through the through holes at the four corners of the base 14 and the corresponding threaded holes on the machine body. Operators use wrenches and other tools to gradually tighten the bolts 15, ensuring the explosion-proof vibration motor... The machine 1 is securely installed on the machine body; then the reinforcing structure 3 is installed, and the reinforcing structure 3 is placed at the left and right ends of the explosion-proof vibration motor 1 respectively. The reinforcing cover 31 of the reinforcing structure 3 covers the left and right ends of the explosion-proof vibration motor 1. When installing the rubber buffer sheets 34 embedded in the circular array on the inner cavity side wall of the reinforcing cover 31, first place the rubber buffer sheets 34 into the arc-shaped grooves 36 opened on the inner cavity side wall of the reinforcing cover 31. The arc-shaped grooves 36 are arranged in a circular array with the central axis of the reinforcing cover 31 as the base point. The inner end face of the rubber buffer sheet 34 The rubber buffer sheet 34 protrudes 3mm-5mm from the inside of the arc-shaped groove 36. After installation, the inner end face of the rubber buffer sheet 34 contacts the outer surface of the vibrating head 12. The two connectors 35 fixed on the front and rear side walls of the outer ring of the reinforcing cover 31 are connected to L-shaped connecting rods 33 at their bottoms. When connecting, one end of the L-shaped connecting rod 33 is mated with the connector 35. The threaded holes at the mating positions of the connector 35 and the L-shaped connecting rod 33 are aligned. The screw 32 is screwed into the threaded hole to fix the connector 35 and the L-shaped connecting rod 33. The L-shaped connecting rod 33 is away from the connector. One end of the 35 is fixedly connected to the machine body that needs to be vibrated. This can be done by pre-drilling holes in the machine body, inserting the end of the L-shaped connecting rod 33 into the holes, and then fixing it with bolts or welding. Finally, the explosion-proof mesh 2 is installed, covering the side of the explosion-proof vibration motor 1 and the reinforcement structure 3 away from the machine body that needs to be vibrated. Screws are then passed through the through holes at the end of the explosion-proof mesh 2 and the threaded holes on the top surface of the reinforcement cover 31, and the screws are tightened so that the explosion-proof mesh 2 covers the explosion-proof vibration motor 1 and the reinforcement structure 3.

[0033] When the explosion-proof vibratory motor starts working, the rotor in the inner cavity of the stator 11 rotates, and the vibrators located inside the vibrating head 12 connected to the left and right ends of the rotor rotate accordingly, generating vibration. The vibration is transmitted to the entire explosion-proof vibratory motor 1 through the vibrating head 12, thereby driving the machine body that needs to be vibrated to vibrate. During the vibration process, the rubber buffer sheet 34 of the reinforcing structure 3 plays a role in buffering and shock absorption. The inner end face of the rubber buffer sheet 34 contacts the outer surface of the vibrating head 12, which can absorb and disperse some of the vibration energy, reducing the impact of vibration on the explosion-proof vibratory motor 1 itself and the connection part with the machine body. At the same time, the reinforcing cover 31 is fixedly connected to the machine body through the L-shaped connecting rod 33, which enhances the stability of the connection between the explosion-proof vibratory motor 1 and the machine body, and prevents the explosion-proof vibratory motor 1 from loosening or shifting during the vibration process. The explosion-proof mesh 2 plays a role in explosion protection, preventing the explosion-proof vibratory motor 1 from generating sparks or other hazards during the vibration process due to internal faults or other reasons, and limiting the potential danger to the area covered by the explosion-proof mesh 2.

[0034] If, during operation, the rubber buffer sheet 34 wears down due to prolonged vibration or changes in the working environment, resulting in a decrease in its cushioning and shock absorption effect, the operation of the explosion-proof vibration motor 1 should be stopped first. Then, the explosion-proof mesh 2 should be disassembled by unscrewing the screws locking the ends of the mesh 2 and removing it. Next, the reinforcement structure 3 should be disassembled by unscrewing the screws 32 securing the connector 35 and the L-shaped connecting rod 33, separating the connector 35 and the L-shaped connecting rod 33. Depending on the actual situation, if the rubber buffer sheet 34 is severely worn, the worn rubber buffer sheet 34 can be removed from the arc-shaped groove 36 on the inner wall of the reinforcement cover 31 and replaced with a new rubber buffer sheet 34. The new rubber buffer sheet 34 is placed in the arc-shaped groove 36, ensuring that the inner end face of the rubber buffer sheet 34 protrudes 3mm-5mm from the inside of the arc-shaped groove 36 and contacts the outer surface of the vibrating head 12; the reinforcing structure 3 is reinstalled, the L-shaped connecting rod 33 is connected to the joint 35 and fixed with screws 32, and then the end of the L-shaped connecting rod 33 away from the joint 35 is fixedly connected to the machine body; finally, the explosion-proof mesh 2 is reinstalled, and the end of the explosion-proof mesh 2 is locked and connected to the top surface of the reinforcing cover 31 with screws, so that the explosion-proof mesh 2 covers the explosion-proof vibration motor 1 and the reinforcing structure 3 again. After the maintenance is completed, the explosion-proof vibration motor 1 can be started again for operation.
