Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, specifically to a modular transmission structure that facilitates rapid maintenance. Background Technology

[0002] In screening equipment such as vibrating screens and linear screens, the transmission structure is the core working component, and its stability directly affects the operating efficiency and screening effect of the equipment. Traditional transmission structures are usually rigidly connected to or integrated into the screen body. When transmission components (such as bearings, shafts, and impellers) malfunction and require maintenance, it is necessary to first disassemble the outer shell of the screen body, connecting bolts, and other components, and sometimes even to hoist the entire screen body. This is not only cumbersome and time-consuming, but also may cause damage to the screen body or other components due to bumps and knocks during the disassembly process, seriously affecting the continuity of production.

[0003] To address the aforementioned issues, while existing technologies have attempted to employ modular transmission structures, most modular structures still suffer from problems such as unreasonable maintenance port design, poor module mobility, and insufficient positioning stability with the screen body, making it difficult to meet the core requirement of rapid maintenance without disassembling the screen body.

[0004] Therefore, there is an urgent need for a modular transmission structure that is compact, reliably positioned, and can be quickly removed for maintenance. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a modular transmission structure that allows for rapid maintenance of transmission components without disassembling the screen body, thereby improving equipment operation and maintenance efficiency and reducing maintenance costs.

[0006] The technical solution adopted by this utility model is as follows: a modular transmission structure that facilitates quick maintenance, characterized in that it includes a frame and a modular transmission box disposed on the frame; the modular transmission box includes a fixing frame, a front fixing plate and a rear fixing plate are provided on the fixing frame, sliding wheels are provided on both sides of the fixing frame, a maintenance and replacement port is provided on the fixing frame, a transmission shaft is provided in the middle of the fixing frame, and a swing block is provided on the transmission shaft; a guide rail is provided on the frame, and the modular transmission box can be pulled out from the frame through the sliding wheels and the guide rail.

[0007] Furthermore, a motor is provided on the front fixed plate, and the motor drives the swing block to rotate along the transmission shaft via a belt.

[0008] Furthermore, the front fixing plate is also provided with an inspection and replacement port.

[0009] Furthermore, there are at least two sliding wheels on each side, symmetrically arranged on both sides of the fixed frame.

[0010] Furthermore, the inspection and replacement port is provided in two or more locations on the upper and lower surfaces of the fixed frame, respectively.

[0011] Furthermore, the clamping device includes a fixed bracket, a sliding block, a placement frame, a clamping block, a screw positioning block, and a clamping screw. The fixed bracket connects the guide rail and the placement frame. The placement frame has an opening on the module side and contains a sliding block and a clamping block. The contact surfaces of the sliding block and the clamping block are inclined. The clamping screw passes through the front fixed plate and engages with the sliding block in a transmission manner. The placement frame is provided with limit screws at both the top and bottom. The limit screws are used to limit the sliding stroke of the sliding block and the clamping block, so that after the clamping screw rotates, it drives the sliding block to squeeze the clamping block and move it towards the module side.

[0012] Furthermore, the front fixing plate is provided with a screw positioning block, which can prevent the screw from retracting when it pushes the sliding block inward.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using the modular transmission box and guide rail, the transmission box can be directly pulled out to the maintenance position. The internal components can be operated through the maintenance and replacement port, which eliminates the tedious steps of disassembling the screen body, greatly shortens the maintenance time, and significantly improves the continuity of production.

[0015] 2. A clamping mechanism is used to fix the transmission box, ensuring that there is no relative displacement between the modular transmission box and the screen body during transmission; the cooperation between the support roller and the guide rail improves the sliding stability, and the overall structure meets the reliability requirements of vibration conditions.

[0016] 3. The clamping mechanism is driven by a screw, which can quickly clamp and release; the cooperation between the linear guide rail and the sliding wheel makes the transmission box easy to pull out, and it can be operated by a single person; it is suitable for various vibrating screens, linear screens and other equipment that require frequent maintenance of transmission components.

Detailed Implementation

[0023] To more clearly illustrate the technical solution of this utility model, the accompanying drawings used in the description will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort. To facilitate understanding of this utility model, a more detailed description of this utility model will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0024] This utility model discloses a modular transmission structure that facilitates rapid maintenance and is a key component of a symmetrical screening and impurity removal device. It includes a frame 200 and a modular transmission box 100 mounted on the frame 200. The modular transmission box 100 has a front fixed plate 101 and a rear fixed plate 102 on its fixing frame 103. Sliding wheels 104 are mounted on both sides of the fixing frame 103, and guide rails 201 are correspondingly provided on the frame 200. Through the cooperation of the sliding wheels 104 and the guide rails 201, the modular transmission box 100 can be smoothly pulled out from the frame 200, enabling maintenance of the transmission components without disassembling the screen body, significantly improving maintenance efficiency. The fixing frame 103 has a maintenance and replacement port 105, and a transmission shaft 107 is located in the middle. A swing block 106 is mounted on the transmission shaft 107. These components are integrated within the modular transmission box 100, forming an independent transmission module, facilitating integrated maintenance and replacement.

[0025] A motor 300 is installed on the front fixed plate 101. The motor 300 drives the swing block 106 to rotate along the transmission shaft 107 via a belt. This transmission method is not only simple in structure, but also allows for maintenance of the motor or transmission components by simply disconnecting the belt connection during maintenance, thus improving the convenience of power transmission system maintenance.

[0026] The front fixed plate 101 is also provided with a maintenance and replacement port 105. This design allows maintenance personnel to perform maintenance operations on the transmission components from multiple angles, such as inspecting and maintaining the belt connection between the motor and the drive shaft. This increases the comprehensiveness and convenience of maintenance and avoids the problem of blind spots caused by a single maintenance angle.

[0027] There are at least two sliding wheels 104 on each side, and they are symmetrically arranged on both sides of the fixed frame 103. This symmetrical layout ensures that the modular transmission box 100 is subjected to uniform force when sliding along the guide rail 201, and the sliding process is smooth and without jamming. This not only ensures the smoothness of maintenance operations, but also enhances the structural stability of the modular transmission box 100 during operation, enabling it to better bear the weight and vibration load of the transmission box and extend the service life of the components.

[0028] The maintenance and replacement ports 105 are provided in two or more locations on the upper and lower surfaces of the fixed frame 103, respectively. The distribution of multiple maintenance ports allows maintenance personnel to select the operating entry point according to different maintenance needs. For example, the bearings on the upper part of the drive shaft and the transmission components on the lower part can be maintained from different maintenance ports, which improves the flexibility and efficiency of maintenance and completely solves the problem of limited operation caused by a single maintenance port.

[0029] like Figure 4 and Figure 5 As shown, a clamping device 400 is provided below the guide rail 201 to clamp the modular transmission box 100, preventing the modular transmission box 100 from shifting due to vibration and other factors during operation, thereby further improving the overall stability of the structure and the reliability of the transmission. The clamping device 400 includes a fixed bracket 401, a sliding block 402, a placement frame 403, a clamping block 404, a screw positioning block 405, and a clamping screw 406. The fixed bracket 401 connects the guide rail 201 and the placement frame 403. The placement frame 403 has a module-side opening and is equipped with a sliding block 402 and a clamping block 404 inside. The contact surfaces of the sliding block 402 and the clamping block 404 are inclined surfaces. The clamping screw 406 passes through the front fixed plate 101 and engages with the sliding block 402 in a transmission cooperation, so that when the clamping screw 406 rotates, it can drive the sliding block 402 to move relative to the clamping screw 406. The placement frame 403 is provided with limit screws 407 at both the top and bottom. The limit screws 407 are used to limit the sliding stroke of the sliding block 402 and the clamping block 404, so that after the clamping screw 406 rotates, it drives the sliding block 402 to squeeze the clamping block 404 to move towards the module side, thereby achieving clamping of the fixed frame 103. In addition, a screw positioning block 405 is provided on the front fixed plate 101. The screw positioning block 405 can prevent the clamping screw 406 from pushing the sliding block 402 inward, ensuring that the clamping of the transmission box 100 can be easily pulled out by loosening the clamping. This clamping device 400 achieves clamping through inclined plane transmission. It has a compact structure and stable clamping force, effectively preventing the modular transmission box 100 from loosening during operation and ensuring the reliability of transmission. At the same time, during maintenance, the modular transmission box 100 can be pulled out simply by loosening the clamping screw 406, without affecting the characteristic of quick maintenance. It achieves a perfect balance between stable clamping during operation and convenient operation during maintenance.

[0030] During actual maintenance, the operator can first loosen the clamping screw 406 to release the clamping device 400, and then pull the modular transmission box 100 so that it slides out of the frame 200 along the guide rail 201 via the sliding wheel 104. After that, the transmission components such as the transmission shaft 107, the throwing block 106, and the belt can be inspected, maintained, or replaced through the multiple maintenance and replacement ports 105 on the fixed frame 103 and the front fixed plate 101. The entire process does not require disassembling the screen body, and the operation is simple and efficient. It fully demonstrates the advantages of modular maintenance of this structure, effectively reduces maintenance costs, and reduces equipment downtime.
