Description

Technical Field

[0001] This utility model relates to the field of vibration platform technology, specifically a vibration platform limiting structure. Background Technology

[0002] A vibrating platform, also known as a compaction table, is mainly used for compacting materials to reduce air and gaps within them. This equipment performs three-dimensional vibrations (lateral, longitudinal, and vertical) driven by a vibration mechanism, and the compaction of materials is achieved by adjusting the excitation force of the vibrating motor.

[0003] The existing Chinese utility model patent with publication number CN211190958U discloses a vibration platform, belonging to the field of vibration platform technology. It includes: a platform body, a vibration motor, a support structure, support rods, limiting rods, a first vibrating screen, a first through hole, an outlet pipe, a second vibrating screen, a second through hole, a third vibrating screen, a third through hole, a fourth vibrating screen, a fourth through hole, a collection tray, a fifth through hole, a force-bearing block, limiting holes, and springs. The vibration motor is fixedly connected to the bottom of the platform body, and four support structures are evenly fixedly connected to the outer wall of the platform body. This utility model, by setting up support rods, limiting rods, force-bearing blocks, and limiting holes, enables the vibration platform to screen objects. During screening, the vibration motor drives the platform body to vibrate, and the springs vibrate together with the platform body, generating resonance, which improves the vibration efficiency of the vibration motor and makes the vibration of the platform body more intense.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, a vibrating platform, also known as a compaction table, is a compaction device used for materials. It is mainly used to reduce air and gaps in the materials. When the vibrating platform is in use, the internal damping mechanism dampens the overall vibration. However, when the vibrating platform is in use, the damping mechanism resonates with the vibrating platform, causing the overall vibration amplitude of the vibrating platform to be too large. This can lead to the loosening of internal parts of the vibrating platform and the easy displacement of items placed on the top of the vibrating platform during vibration. All these problems affect the use of the device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a vibration platform limiting structure that effectively prevents resonance between the damping mechanism and the vibration platform during use, thus avoiding excessive overall vibration amplitude of the vibration platform and subsequent loosening of internal parts. This solves the aforementioned technical problems.

[0007] Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a vibration platform limiting structure, including a device structure component, wherein a vibration limiting component is installed at the upper end of the device structure component to buffer the vibration force of the overall structure and prevent the subsequent upper end of the device from having a large vibration force; and a position limiting component is installed at the upper end of the vibration limiting component to facilitate the placement of an object for vibration and to prevent the subsequent vibration force from being too large and moving the position of the object.

[0009] The vibration limiting component has a first rubber block installed at its upper end, a damping spring installed at its lower end, a second rubber block installed at its lower end, and a buffer spring installed at its lower end. The buffer spring is installed on both sides of the second rubber block to facilitate further buffering of the transmitted vibration force.

[0010] The position limiting component has a first mounting slot installed at its upper end, and a second mounting slot installed at the outer end of the first mounting slot. A first limiting plate is installed at the upper end of the second mounting slot, and a second limiting plate is installed at the upper end of the first limiting plate.

[0012] As a preferred embodiment of this utility model, a fixing plate is installed on the upper end of the vibration limiting component. The fixing plate is installed on the upper end of the buffer spring, which facilitates the subsequent fixing of the buffer spring.

[0013] As a preferred technical solution of this utility model, a platform structure is installed on the upper end of the position limiting component. The platform structure places the items that need to be vibrated and screened, which is convenient for subsequent use.

[0014] As a preferred embodiment of this utility model, the vibration limiting component is installed on the upper end of the bracket in the device structure component, and the position limiting component is installed on the upper end of the first rubber block in the vibration limiting component.

[0016] As a preferred embodiment of this utility model, the second rubber block is installed on the upper end of the bracket, the buffer spring and the fixing plate are installed above the bracket, and the number of buffer springs is two.

[0017] As a preferred embodiment of this utility model, the platform structure is installed on the upper end of the first rubber block, the first mounting groove connects the first limiting plate, the second mounting groove connects the second limiting plate, and the side length of the first mounting groove is smaller than that of the second mounting groove.

[0018] Compared with the prior art, the present invention provides a vibration platform limiting structure with the following advantages:

[0019] 1. This utility model, through the design of the overall device, includes a vibration limiting component with a first rubber block and a second rubber block installed. The rubber blocks buffer the vibration force generated by the upper platform. Damping springs are installed between the rubber blocks to effectively buffer the vibration of the overall structure. Buffer springs are installed on both sides of the second rubber block to buffer the vibration force on both sides of the rubber block, preventing excessive vibration of the overall structure. A platform is installed at the upper end of the position limiting component, with a first mounting groove and a second mounting groove installed at the upper end of the platform. A first limiting plate is connected and placed through the first mounting groove, and a second limiting plate is connected and placed through the second mounting groove. The limiting plates intercept the vibration position of items placed on the upper end of the platform, preventing items from falling. This effectively prevents the vibration platform from resonating with the internal shock absorption mechanism during use, which could cause excessive vibration amplitude, leading to loosening of internal parts and easy displacement of items placed on the upper end during vibration.

[0029] With the above structure, the device structure component 1 facilitates the installation of the upper components and the subsequent use of the overall device; the vibration limiting component 2 helps to buffer the vibration force of the overall structure and prevents the upper part of the device from vibrating too much; and the position limiting component 3 facilitates the placement of items for vibration and prevents the subsequent vibration force from moving the position of the items due to excessive vibration.

[0030] Please see Figure 1 - Figure 4 The vibration limiting component 2 is installed on the upper end of the bracket 101 in the device structure component 1, the position limiting component 3 is installed on the upper end of the first rubber block 201 in the vibration limiting component 2, the bracket 101 has a U-shaped structure, and the structural plate 102 is installed on the lower end of the platform structure 301.

[0031] The above structure allows for the connection of the upper vibration limiting component 2 by installing the bracket 101, facilitating subsequent use. The structural plate 102 is installed on the upper end of the bracket 101, facilitating the subsequent installation of the vibration structure 103. The vibration structure 103 is installed on both sides of the structural plate 102, facilitating the subsequent vibration of the upper end of the platform structure 301.

[0032] Please see Figure 1 - Figure 4 The upper end of the vibration limiting component 2 is equipped with a fixing plate 205, the second rubber block 203 is installed on the upper end of the bracket 101, and the buffer spring 204 and the fixing plate 205 are installed above the bracket 101. There are two buffer springs 204.

[0033] With the above structure: the vibration transmitted by the upper platform structure 301 is buffered by installing the first rubber block 201; the damping spring 202 is installed at the lower end of the first rubber block 201, so that the upper platform structure 301 can be driven in the future while buffering the overall vibration; the second rubber block 203 is installed at the lower end of the damping spring 202, so that the buffer springs 204 on both sides can be connected in the future; the buffer springs 204 are installed on both sides of the second rubber block 203, so that the transmitted vibration force can be buffered again in the future; the fixing plate 205 is installed at the upper end of the buffer spring 204, so that the buffer spring 204 can be fixed in the future.

[0034] Please see Figure 1 - Figure 4 The platform structure 301 is installed on the upper end of the first rubber block 201. The first mounting groove 302 connects the first limiting plate 304, and the second mounting groove 303 connects the second limiting plate 305. The side length of the first mounting groove 302 is smaller than that of the second mounting groove 303.

[0035] With the above structure: by installing the platform structure 301, the items that need to be vibrated and screened are placed for subsequent use.

The first limiting plate 304 and the second limiting plate 305 are used together to facilitate the subsequent position restriction of items of different sizes.

[0036] In use, firstly, the material to be vibrated and screened is placed on the upper end of the platform structure 301. The vibrating structure 103 on the upper end of the structure plate 102 is then started by a motor, causing the upper end of the platform structure 301 to vibrate. To prevent the material from falling off during subsequent vibrations, a first mounting groove 302 and a second mounting groove 303 are installed on the upper end of the platform structure 301. The limiting plates are positioned according to the size of the material. When the material is small, the first limiting plate 304 is installed inside the first mounting groove 302; when the material is large, the second limiting plate 305 is installed inside the second mounting groove 303. When 301 vibrates, the vibration force at the upper end is transmitted to the interior of the first rubber block 201 at the lower end. The first rubber block 201 is made of rubber material, which has good elasticity and absorption properties, and can absorb the impact energy of vibration, reducing structural deformation and damage. A damping spring 202 is installed at the lower end of the first rubber block 201 to buffer the vibration force. A second rubber block 203 is installed at the lower end of the damping spring 202. The second rubber block 203 has the same structure as the first rubber block 201. Buffer springs 204 are installed on both sides of the second rubber block 203 to effectively buffer the remaining vibration force.
