Description

Technical Field

[0001] This invention relates to the field of nuclear industry material handling technology, specifically to a transfer and guiding device for precision containers. Background Technology

[0002] In the nuclear industry, to meet the requirements of specific processes, it is often necessary to use transfer equipment to efficiently and accurately transport container structures to the target workstation. These container structures are usually quite precise, and their posture stability and structural safety must be ensured during transportation to prevent tipping or falling. At the same time, since the containers are mostly rectangular or cubic in shape, their orientation must be maintained during transportation, and they must be accurately moved to the designated position according to process requirements to facilitate subsequent gripping and transfer operations.

[0003] Currently, common conveyor mechanisms used in this field include roller conveyors, belt conveyors, chain conveyors, and air cushion conveyors. Among them, roller conveyors are widely used due to their advantages such as high load-bearing capacity, stable operating speed, high reliability, and low failure rate. However, due to their structural characteristics, this type of mechanism still has several technical defects in the process of transporting containers, mainly manifested in insufficient transmission accuracy, poor cargo safety protection, poor guiding performance, and limited positioning accuracy.

[0004] With the increasing demands for high-quality transport of precision container structures in industries such as nuclear power, existing conveying mechanisms can no longer fully meet the actual needs of production in terms of precision, safety, and guidance control. Therefore, there is an urgent need to develop a transport and guidance mechanism that can achieve high-precision transport, reliable guidance, and accurate positioning of goods, in order to fill the gaps in existing technologies and improve the technological level and operational reliability of container transfer in nuclear industry production. Summary of the Invention

[0005] The purpose of this invention is to provide a transfer and guiding device for precision containers, which enables high-precision transfer, reliable guidance and accurate positioning of goods, thereby filling the shortcomings of the prior art and improving the process level and operational reliability of container transfer in nuclear industry production.

[0006] This invention is achieved through the following technical solution:

[0007] The transmission and guiding device for precision housings includes a frame, a drive wheel set, a driven wheel set, a clamping mechanism, protective rolling elements, and limiting elements; the drive wheel set and the driven wheel set are fixed at intervals along the Y direction at both ends of the frame, the drive wheel set is used to drive the housing, and together with the driven wheel set, they form a rolling support surface that carries the housing;

[0008] The clamping mechanism is configured in two sets and spaced apart along the Y direction to clamp the box located on the rolling support surface from the X direction; the protective rolling elements are multiple and are installed at intervals along the Y direction on both sides of the frame; the limiting members are configured in two sets and are respectively arranged at both ends of the frame along the Y direction.

[0009] In one possible design, the clamping mechanism includes a fixed clamp, a movable clamp, and a drive member. The movable clamp is movably connected to the fixed clamp. One end of the drive member is connected to the fixed clamp, and the other end is connected to the movable clamp to push the movable clamp closer to or away from the fixed clamp.

[0010] In one possible design, the movable clamp is movably connected to the fixed clamp via a sliding structure; the sliding structure includes a guide rail and a slider; the guide rail is fixedly arranged in a direction parallel to the X direction; the slider is slidably arranged on the guide rail and fixedly connected to the movable clamp; the driving member is used to drive the movable clamp to move along the guide rail via the slider.

[0011] In one possible design, the drive member is connected to the movable clamp via a transmission structure, the transmission structure including a drive wheel, a driven wheel, and a transmission belt. The drive wheel is connected to the output shaft of the drive member, and the driven wheel is disposed opposite to the drive wheel. The transmission belt is wound around the outer periphery of the drive wheel and the driven wheel, and the transmission belt is connected to the movable clamp.

[0012] In one possible design, the inner side of the transmission belt is provided with teeth, and the movable clamp is provided with a connecting block adapted to the transmission belt; the connecting block is provided with a guide groove, and the side wall of the guide groove is provided with a tooth groove that mates with the teeth; the transmission belt is embedded in the guide groove, and the teeth mate with the tooth groove.

[0013] In one possible design, the clamping mechanism further includes two sets of pressure plates, which are respectively arranged on the opposite inner sides of the fixed clamp and the movable clamp, so as to jointly clamp the box body through the frictional force of the contact surfaces of the pressure plates.

[0014] In one possible design, the pressure plate is detachably connected to the fixed clamp and / or movable clamp by fasteners.

[0015] In one possible design, both the fixed clamp and the movable clamp include a positioning plate and an L-shaped working plate. The positioning plate is horizontally positioned and fixedly connected to the working plate. The working plate is connected to a pressure plate for pressing against the box body.

[0016] In one possible design, the work plate is provided with a reinforcing ridge; and / or, the work plate is provided with weight-reducing holes.

[0017] In one possible design, the drive wheel assembly includes a driver and a drive wheel, with the fixed end of the driver connected to the frame and its output end connected to the drive wheel; the drive wheel is rotatably connected to a drive wheel that is parallel to the driven wheel assembly.

[0018] In one possible design, the driven wheel assembly includes at least two parallel and spaced-apart rolling wheels.

[0019] In one possible design, the protective rolling element is configured as a roller, which is connected to the frame via a bearing housing;

[0020] The number of protective rolling elements is at least two sets, and they are evenly spaced along the Y direction.

[0021] The advantages of this invention over the prior art are as follows:

[0022] The working process of the transfer and guiding device used for precision housings is as follows:

[0023] The housing is placed on the first transfer platform, where the driving wheel assembly rotates, cooperating with the driven wheel assembly to drive the housing along the Y-axis toward the second transfer platform. When the housing is on either transfer platform, the corresponding clamping mechanism moves synchronously from both sides in the X-axis, gripping the housing and providing lateral limitation and posture correction. This process ensures that the housing's central axis remains aligned with the transfer direction. Throughout the housing's transfer from the first to the second transfer platform, multiple protective rolling elements, installed on both sides of the frame and spaced apart along the Y-axis, remain in contact with the housing's side walls, continuously guiding the housing along a preset path through rolling friction, limiting its lateral displacement, and providing anti-tipping protection. When the housing reaches the end of the frame, a limiting element at that location acts as a mechanical stop, precisely limiting the housing's final position in the Y-axis, ensuring it stops accurately at the predetermined workstation.

[0024] The above technical solution, by setting clamping mechanisms on two transmission platforms and combining them with limiting components at both ends, allows for joint positioning of the container in both the X and Y directions. The clamping mechanisms enable the container to move accurately along a preset direction, while the limiting components define its final position, thus solving the problem of insufficient positioning accuracy in traditional conveying mechanisms and meeting the stringent positional requirements of precision containers. Continuously arranged protective rolling elements along the entire transmission path provide lateral guidance and protection for the container throughout the process. Based on the rolling contact characteristics of the protective rolling elements, it effectively prevents the container from deviating from its designated path and reliably prevents it from tipping over or falling during high-speed transmission or under uneven stress through lateral constraint torque, thereby ensuring the safety of the precision container itself and its contents.

[0025] This device organically integrates drive transmission, attitude correction, lateral protection, and end-positioning functions onto a unified frame. The transmission platform is responsible for drive, the clamping mechanism for lateral attitude control, the protective rolling elements for full-process guidance and anti-tipping, and the limiting components for longitudinal positioning. All components work closely together in spatial layout and functional sequence to form a highly efficient and reliable precision box-type transmission and guidance system that operates smoothly and has strong overall integrity.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0035] According to a first aspect of this disclosure, a transfer guide device for a precision housing is provided. Figures 1 to 6 Specific embodiments thereof are shown.

[0036] See Figures 1 to 6 As shown, the transmission guide device for the precision housing 8 includes a frame 1, a drive wheel set 4, a driven wheel set 5, a clamping mechanism 3, protective rolling elements 6, and limiting elements 7. The drive wheel set 4 and the driven wheel set 5 are fixed at intervals along the Y direction at both ends of the frame 1. The drive wheel set 4 is used to drive the housing 8 and together with the driven wheel set 5, forms a rolling support surface that supports the housing 8. The clamping mechanism 3 is configured in two sets and is spaced apart along the Y direction to clamp the housing 8 located on the rolling support surface from the X direction. There are multiple protective rolling elements 6, which are spaced apart along the Y direction on both sides of the frame 1. The limiting elements 7 are configured in two sets and are respectively arranged at both ends of the frame 1 along the Y direction.

[0037] The operation of the transmission guide device for the precision case 8 is as follows: First, the case 8 is placed at one end (e.g., the receiving end) of the rolling support surface formed by the driving wheel set 4 and the driven wheel set 5. The driving wheel set 4 starts, driving the case 8 to move along the Y direction (transmission direction) through friction. During transmission, multiple protective rolling elements 6 installed on both sides of the frame 1 contact the sides of the case 8. These protective rolling elements 6, spaced apart along the Y direction, together form a continuous guide channel, which can effectively limit the displacement of the case 8 in the X direction (lateral direction), automatically correct the deviation of its running trajectory, and provide lateral support by relying on its vertical installation shape, preventing the case 8 from tipping over during high-speed or unstable transmission. When the case 8 moves to the position that requires precise positioning (e.g., reaching the receiving end), the two sets of clamping mechanisms 3 installed at this position start to work, and can move synchronously towards each other in the X direction, thereby clamping the case 8 from both sides, thus completing the precise positioning and attitude correction of the case 8 in the lateral direction, ensuring that it is in the preset ideal position. Finally, when the housing 8 reaches the end of the transmission path, the limiting member 7 set at the end of the frame 1 acts as a physical barrier to ensure that the housing 8 stops accurately at the target position in the Y direction, preventing it from falling off due to inertia or driving error.

[0038] Through the above technical solution, a triple-coordinated positioning and protection structure of "process-end-end" is formed by the continuous guidance of the protective rolling elements 6, the precise positioning of the end of the clamping mechanism 3, and the end stop of the limiting component 7. This solves the problems of deviation, inaccurate positioning, and side-tipping and falling that may occur in the housing 8 during the entire transmission process, greatly improving the accuracy and safety of transmission. The rolling support surface formed by the driving wheel group 4 and the driven wheel group 5 ensures smooth driving. The multiple sets of protective rolling elements 6 arranged at intervals along the Y direction form a continuous and flexible constraint on the long side of the housing 8, which can dynamically correct the orientation of the housing 8 and ensure that the housing 8 maintains a stable posture and preset directionality throughout the entire transmission path. By modularizing and integrating the guiding (protective rolling elements 6) and positioning (clamping mechanism 3, limiting component 7) functions onto the frame 1, the structural layout is reasonable and compact. The functions of each component are clearly defined and work together, avoiding complex external control structures, reducing the overall failure rate, and ensuring reliable operation.

[0039] It should be noted that directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the outline of the component; "inner" refers to the direction towards the component, and "outer" refers to the direction away from it. Furthermore, terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Also, in the accompanying drawings, the same reference numerals in different drawings represent the same element. It should be noted that "and / or" in the text refers to A and / or B, indicating that there are three possible scenarios: only A, only B, or both A and B. Conversely, " / and" in the text refers to A and B, indicating that there are two possible scenarios: only A and both A and B.

[0040] Additionally, the orientation can be referenced using a spatial rectangular coordinate system. In this disclosure, the dimensions of the frame 1 can be used as the orientation reference, where the width direction of the frame 1 is the X direction, the length direction of the frame 1 is the Y direction, and the height direction of the frame 1 is the Z direction.

[0041] In one embodiment provided in this disclosure, the clamping mechanism 3 includes a fixed clamp 31, a movable clamp 32, and a driving member 33. The movable clamp 32 is movably connected to the fixed clamp 31. One end of the driving member 33 is connected to the fixed clamp 31, and the other end is connected to the movable clamp 32, so as to push the movable clamp 32 closer to or away from the fixed clamp 31.

[0042] The drive unit 33 synchronously pushes the movable clamp 32 to move towards the fixed clamp 31, so that the clamping mechanism 3 can apply uniform clamping force from both sides of the box 8 in the X direction. This symmetrical clamping method can automatically correct and position the box 8 on the center line of the transmission channel, ensuring the accuracy of the box 8's posture, and effectively avoiding jamming, deflection or surface damage to the box 8 caused by uneven force. It is especially suitable for precision boxes 8 with extremely high requirements for surface protection and positional accuracy.

[0043] In one possible design, the movable clamp 32 is movably connected to the fixed clamp 31 via a sliding structure 37; the sliding structure 37 includes a guide rail 371 and a slider 372; the guide rail 371 is fixedly arranged in a direction parallel to the X direction; the slider 372 is slidably arranged on the guide rail 371 and fixedly connected to the movable clamp 32; the driving member 33 is used to drive the movable clamp 32 to move along the guide rail 371 via the slider 372.

[0044] When the drive unit 33 receives a control signal, it begins to operate, and the output driving force (ultimately a push or pull force in a linear direction) can be transmitted to the movable clamp 32 connected to the output end of the drive unit 33. Since the movable clamp 32 forms a sliding engagement with the fixed guide rail 371 through the slider 372, the power generated by the drive unit 33 is converted into precise linear motion of the slider 372 along the extension direction of the guide rail 371. Driven by the slider 372, the movable clamp 32 smoothly approaches or moves away from the fixed clamp 31 along a trajectory parallel to the X direction, thereby realizing the clamping or releasing operation of the housing.

[0045] The fixed guide rail 371 provides a precise and immovable reference path for the movement of the movable clamp 32, effectively constraining the movable clamp 32 so that it moves strictly along a straight track parallel to the X direction under the drive of the drive component 33. This effectively eliminates possible swaying, warping or twisting during the movement, thereby ensuring that the movable clamp 32 and the fixed clamp 31 remain precisely aligned throughout the entire stroke, achieving precise and symmetrical clamping of the housing 8, and avoiding uneven force, positioning errors or surface damage to the housing 8 caused by misalignment of the clamps.

[0046] In this disclosure, the guide rail 371 and slider 372 are made of high-rigidity materials, and their combination can withstand the forces and torques from the sides of the housing 8. When the drive member 33 pushes the movable clamp 32 to clamp the housing 8, the huge clamping force and the possible off-center load torque are evenly distributed and transmitted to the entire fixed guide rail 371 and its supporting structure through the slider 372, so that the entire clamping mechanism 3 has excellent anti-deformation ability and overall stability, can reliably clamp the heavy housing 8, and maintain its accuracy and reliability in long-term use.

[0047] Furthermore, the sliding structure 37 is configured in two sets and spaced apart along the Y direction. In this way, the two sets of sliding structures 37 can form a stable guide structure, thereby effectively resisting the deflection moment (i.e. torsional deformation) around the Z-axis (vertical axis) and the pitching moment around the X-axis that may be generated by uneven load or installation stress during the movement of the movable clamp 32, ensuring that the movable clamp 32 remains parallel to the fixed clamp 31 throughout the entire stroke.

[0048] In one possible design, the drive member 33 is connected to the movable clamp 32 via a transmission structure 38. The transmission structure 38 includes a drive wheel 381, a driven wheel 382, ​​and a transmission belt 383. The drive wheel 381 is connected to the output shaft of the drive member 33, and the driven wheel 382 is disposed opposite to the drive wheel 381. The transmission belt 383 is wound around the outer periphery of the drive wheel 381 and the driven wheel 382, ​​and is connected to the movable clamp 32.

[0049] When the drive unit 33 is activated, its output shaft drives the transmission wheel 381 connected to it to rotate. Power is transmitted to the driven wheel 382 via the transmission belt 383 wrapped around the outer circumference of the transmission wheel 381 and the driven wheel 382, ​​causing the entire transmission belt 383 to form a closed-loop motion. Since a portion of the transmission belt 383 is fixedly connected to the movable clamp 32, the linear motion of the transmission belt 383 is directly converted into the linear displacement of the movable clamp 32. By controlling the direction of the drive unit 33, the transmission belt 383 can smoothly move the movable clamp 32 along a trajectory parallel to the X-direction towards or away from the fixed clamp 31, thereby completing the clamping or releasing operation of the housing.

[0050] Based on the structural features of the transmission belt 383, its inherent elasticity can effectively absorb the impact and vibration generated when the drive component 33 starts, stops, or undergoes sudden speed changes. This flexible transmission characteristic makes the movement of the movable clamp 32 more stable and smooth, and reduces operating noise.

[0051] In this disclosure, see Figure 2 , Figure 3 and Figure 5 As shown, the inner side of the transmission belt 383 is provided with teeth 384, and the movable clamp is provided with a connecting block 39 adapted to the transmission belt 383. The connecting block 39 is provided with a guide groove 391, and the side wall of the guide groove 391 is provided with a toothed groove 392 that mates with the teeth. The transmission belt 383 is embedded in the guide groove 391, and the teeth 384 mate with the toothed groove 392. When the transmission belt 383 moves, it can drive the slider 372 to move relative to it.

[0052] Specifically, the connecting block is connected to the positioning plate of the movable clamp via a slider. In one design, the connecting block can be detachably connected to the movable clamp. In another design, the connecting block can be fixedly connected to the movable clamp.

[0053] In this disclosure, the drive unit 33 is fixedly mounted on the frame 1 or any other suitable location.

[0054] Specifically, the drive component is a motor. This motor is connected to a reducer (or gear assembly), which allows for the adjustment and integration of the output force, thereby reducing speed and increasing torque, and enabling power to be efficiently transmitted to the transmission wheel.

[0055] In this application, both the drive wheel 381 and the driven wheel 382 are configured as gears. Furthermore, the drive wheel 381 and the driven wheel 382 are configured as spur gears. The teeth on the inner side of the transmission belt 383 are formed to mesh with the spur gears, thereby efficiently and smoothly transmitting power under the drive of the drive wheel.

[0056] In one possible design, the clamping mechanism 3 also includes a pressure plate 34, which is configured in two sets and respectively located on the inner sides of the fixed clamp 31 and the movable clamp 32, so as to jointly clamp the box body 8 by the friction of the contact surfaces of the pressure plates 34.

[0057] As a component that directly contacts the surface of the housing 8, the pressure plate 34 can be made of or treated with a material with a high coefficient of friction (such as rubber, polyurethane, etc.) to increase clamping friction and ensure that the housing 8 will not slip due to inertia or vibration during transportation. At the same time, compared with direct contact from metal claws, the flexible or non-metallic pressure plate 34 can effectively avoid scratches or indentations on the surface of the precision housing 8, ensuring the safety and practicality of the housing 8 during handling.

[0058] Furthermore, the pressure plate 34 is detachably connected to the fixed clamp 31 and / or the movable clamp 32 via fasteners. This fastener connection (such as bolts) makes replacing the pressure plate 34 extremely simple and quick. Maintenance personnel do not need to disassemble the complex clamping mechanism 3; they only need to remove a few fasteners to complete the replacement, shortening maintenance time, lowering the technical threshold and labor costs, thereby reducing downtime caused by routine maintenance and effectively improving equipment production efficiency and utilization.

[0059] Based on actual production needs, various pressure plates 34 made of different materials (such as rubber, polyurethane, nylon), with different surface patterns (such as smooth or patterned), or with different hardness can be prepared in advance. When the material of the conveying box 8 changes, the surface finish requirements are different, or the clamping friction needs to be adjusted in the process, the operator can quickly replace the matching pressure plate 34, enabling the same equipment to flexibly adapt to diverse production tasks and enhancing the flexibility of the production line.

[0060] Manufacturing the pressure plate 34 separately from the gripper body and assembling them with fasteners simplifies the structure and machining of each individual component. During manufacturing, this reduces the cost and scrap rate of machining large, complex components as a whole. During operation, since only low-cost spare parts for the pressure plate 34 need to be stocked and replaced, instead of replacing the expensive entire gripper assembly, the long-term operating and spare parts management costs of the equipment are effectively controlled.

[0061] In one embodiment provided in this disclosure, both the fixed clamp 31 and the movable clamp 32 include a positioning plate 301 and an L-shaped working plate 302. The positioning plate 301 is horizontally arranged and fixedly connected to the working plate 302; the working plate 302 is connected to a pressure plate 34 for pressing against the box body. The L-shaped working plate 302 and the horizontally arranged positioning plate 301 together form a rigid frame with excellent bending and torsional resistance. When the pressure plate 34 clamps the box body 8, the lateral force acting on the pressure plate 34 is effectively transmitted and distributed to the entire positioning plate 301 and support base by the L-shaped working plate 302, enhancing the overall rigidity and stability of the clamp body, preventing structural deformation or vibration that may occur when subjected to huge clamping forces, thereby providing a reliable mechanical basis for the precise positioning of the box body.

[0062] The L-shaped configuration provides ample installation and operational space for the working plate 302 in both the vertical and horizontal directions. The vertical section provides a stable mounting base for the pressure plate 34 and can be adapted to the height of the housing 8; the horizontal section's positioning plate 301 facilitates flexible layout and fixation on the frame 1. This structure effectively avoids the moving parts of the lower transmission platform, achieving compact space utilization and ensuring that the clamping and transmission functions do not interfere with each other and work together.

[0063] Specifically, the working plate 302 is provided with a reinforcing ridge 35. The reinforcing ridge 35 effectively improves the bending and torsional stiffness of the working plate 302 by increasing the moment of inertia of the material section along critical stress paths. Specifically, in this disclosure, the reinforcing ridge 35 is located on the centerline of the working plate 302. The working plate 302 is provided with weight-reducing holes 36. The weight-reducing holes 36 are located in areas that do not primarily bear loads. By removing excess material, the overall structure of the working plate 302 is made lighter. Thus, the working plate 302 achieves the maximum specific stiffness (stiffness to weight ratio) while maintaining the lowest possible weight, simultaneously achieving the dual goals of structural lightweighting and high rigidity.

[0064] In one embodiment provided in this disclosure, the drive wheel assembly 4 includes a driver 41 and a drive wheel 42. The fixed end of the driver 41 is connected to the frame 1, and its output end is drivenly connected to the drive wheel 42. The drive wheel 42 is rotatably connected to a drive wheel assembly 5 that is parallel to the driven wheel assembly 5.

[0065] When the device is started, the driver 41 (such as a motor) is energized and operates. Since the fixed end of the driver 41 is securely connected to the frame 1, its stability during operation is ensured. The output end of the driver 41 transmits power to the drive wheel 42, which is connected to it, causing the drive wheel 42 to rotate around its axis. The drive wheel 42 and the driven wheel set 5 are arranged parallel to each other, forming a flat rolling support surface. The rotating drive wheel 42 drives the housing 8 to move smoothly and continuously along the predetermined Y-axis (transmission direction) through the friction between its surface and the bottom surface of the housing 8.

[0066] By adopting a direct drive connection between the driver 41 and a single drive wheel 42, a simple and efficient point-to-point drive mode is constructed, which reduces intermediate transmission links, reduces energy loss during power transmission, and realizes independent and precise control of each drive unit. This allows the drive wheel group 4 to easily achieve start-stop buffering, speed adjustment, and even synchronous control, thereby improving the smoothness and positioning accuracy of the transmission of the housing 8.

[0067] The drive unit 41 is fixed to the frame 1, while the drive wheel 42 and the driven wheel set 5 are arranged in parallel. This layout allows the drive unit to be installed in a distributed manner as a modular component. Depending on the weight and length of the housing 8, multiple sets of such drive wheel sets 4 can be flexibly arranged at different positions on the frame 1 to share the load, thereby improving the load-bearing capacity of the entire device. It is suitable for transporting heavy or light precision housings 8 of different specifications.

[0068] The rigid connection between the fixed end of the drive unit 41 and the frame 1 ensures the stability of the drive source during operation. Meanwhile, the parallel arrangement of the drive wheel 42 and the driven wheel set 5 ensures that the housing 8 is subjected to uniform force during transmission, preventing deviation or jamming due to drive force direction bias. This helps reduce the failure rate of the mechanism and ensures long-term reliable operation of the equipment in harsh industrial environments.

[0069] In this disclosure, the drive wheel 42 is connected to the frame 1 via a positioning seat, which facilitates the installation and layout of the drive wheel 42.

[0070] Specifically, the driven wheel assembly 5 includes at least two parallel and spaced-apart rolling wheels, which together form a distributed support surface. This evenly distributes the weight of the precision housing 8, effectively preventing localized stress concentration or deformation at the bottom of the housing 8 due to insufficient support points or uneven support surfaces. Compared to a plate structure with large-area continuous support, the spaced-apart rolling wheels transform the sliding friction between the housing 8 and the support surface into rolling friction, significantly reducing frictional resistance.

[0071] The gaps between the rollers provide space for dust, debris, and other foreign objects to fall off, preventing accumulation and jamming, and improving the equipment's adaptability in complex industrial environments. At the same time, this modular shaft structure facilitates the inspection, replacement, and maintenance of individual components, thereby enhancing the equipment's maintainability and lifespan.

[0072] Furthermore, the rollers are also connected to the frame 1 via positioning seats. The rollers can be located on one side of the drive wheel 42 or distributed on both sides of the drive wheel 42. Those skilled in the art can flexibly configure them according to actual needs.

[0073] In one embodiment provided in this disclosure, the protective rolling element 6 is configured as a roller, which is connected to the frame 1 via a bearing housing. Using a roller as the contact component transforms the lateral sliding friction of the housing 8 into rolling friction, thereby reducing the motion resistance between them. This effectively constrains its lateral displacement and prevents deviation, while ensuring smooth passage of the housing 8 in the transmission direction. It avoids jamming, vibration, or unstable transmission of the housing 8 due to excessive frictional resistance, helping to ensure the accurate turnover of the housing 8 to its destination.

[0074] The roller is connected to the frame 1 through a dedicated bearing housing. The bearing housing not only provides precise positioning and firm clamping for the roller shaft, ensuring the concentricity and stability of the roller during rotation, but also the rolling bearing installed inside ensures that the roller can rotate freely and easily. This allows the protective rolling element 6 to withstand continuous lateral loads and impacts, resulting in good mechanical durability and operational reliability.

[0075] In one embodiment provided in this disclosure, the number of protective rolling elements 6 is at least two sets, arranged at intervals along the Y direction, thereby creating an uninterrupted continuous lateral constraint channel for the housing 8. In this way, regardless of whether the housing 8 is at the beginning, middle, or end of the transmission, its lateral direction can be guided and supported in a timely and effective manner, which can effectively reduce the risk of the housing 8 deviating, getting stuck, or even overturning due to local lack of guidance during long-distance transmission.

[0076] In this disclosure, every two pairs of protective rolling elements form a group.

[0077] Furthermore, the protective rolling elements 6 are configured as four groups spaced apart along the length direction.

[0078] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0079] Finally, it should be noted that this invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention, which should be determined by the claims, and the specification can be used to interpret the claims.
