Description

Technical Field

[0001] This utility model relates to the technical field of track gauge baffle processing and transfer device, and in particular to a V-shaped track gauge baffle mechanical structure. Background Technology

[0002] In railway track systems, gauge blocks, as key components, play a crucial role. They not only apply horizontal clamping force to the rails but also adjust the rail positions to ensure gauge stability, thus having a decisive impact on the safe and smooth operation of trains.

[0003] The manufacturing process of gauge blocks involves multiple positioning and processing technologies. Taking the labeling process as an example, this process aims to facilitate the later traceability of gauge blocks, ensuring product quality and accountability. To improve production efficiency, we generally use conveyor belt technology to transfer gauge blocks, ensuring that they can smoothly transition from one processing stage to the next, achieving seamless connection.

[0004] Currently, a typical gauge baffle transfer device usually consists of two support frames positioned at the front and rear, and multiple support rollers with horizontal central axes. The support rollers are rotatably connected to the support frames, and multiple support rollers are arranged side by side at equal intervals between the two support frames to provide a support plane for the gauge baffle, allowing it to be placed on it for transfer.

[0005] However, current conveyor belts have significant problems when transferring gauge blocks. Because the gauge blocks are not effectively positioned and secured on the conveyor belt, it is difficult to ensure they remain in their intended positions. This disrupts subsequent processing steps, such as labeling. To ensure processing accuracy and quality, the position of the gauge blocks must be individually adjusted in subsequent processes. This not only increases operational steps and time costs, reducing overall production efficiency, but also may lead to decreased processing accuracy due to errors caused by manual adjustments, ultimately affecting the quality of the gauge blocks.

[0006] In summary, current gauge baffle transfer devices are insufficient in ensuring the accuracy of gauge baffle positioning, failing to meet the demands of efficient and precise production. Therefore, there is an urgent need to develop a new type of gauge baffle transfer and support device to address the problems in existing technologies and improve positioning accuracy and production efficiency during gauge baffle production. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes a V-shaped gauge baffle mechanical structure. This design simplifies the operation process and eliminates the need for separate adjustments to the gauge baffle position later, effectively solving the problem of accurately controlling the gauge baffle position during transport in existing devices.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A V-shaped gauge baffle mechanical structure includes two support frames arranged front to back with an arc-shaped horizontal projection. The central axes of the two support frames coincide, and multiple support rollers are arranged between the two support frames, with the multiple support rollers arranged side by side at equal intervals between the two support frames. The structure is characterized by further including two positioning plates arranged front to back, located on the lower side of the support frames. One positioning plate is fixedly connected to an adjacent support frame, and the other positioning plate is slidably connected to an adjacent support frame. Each positioning plate is detachably connected with vertically axially limiting rods, which are inserted between two adjacent support rollers. The upper end face height of each limiting rod is greater than the upper end face height of the support roller. A driving mechanism is provided on one side of the positioning plate slidably connected to the support frame, and the positioning plate slidably connected to the support frame moves linearly back and forth through the driving mechanism.

[0010] Preferably, each positioning plate has a through hole, the limiting rod is inserted into the through hole, and the lower end of each limiting rod is screwed with two locking nuts by external threads, the near ends of the two locking nuts respectively abutting against the corresponding positioning plate.

[0011] Preferably, each of the limiting rods is coaxially fixedly connected to a bearing at its upper end, and a contact ring is sleeved on the outside of the bearing, and the contact ring is rotatably connected to the corresponding limiting rod through the bearing.

[0012] Preferably, the distance between the two positioning plates exhibits a U-shaped curve, with the distance between the two ends of the two positioning plates being greater than the distance between their middle sections.

[0013] Preferably, the driving mechanism includes a screw, which is rotatably connected to an adjacent support frame, and a follower block is screwed into the middle section of the screw, which is fixedly connected to a corresponding positioning plate.

[0014] Preferably, a positioning block I is fixedly connected to the lower side of each positioning plate, and a positioning hole I is formed through the positioning block I. Furthermore, a positioning block II is fixedly connected to the lower side of each support frame, and a positioning hole II is formed through the positioning block II corresponding to the positioning hole I. A positioning rod is coaxially inserted into the interior of each positioning hole I and the corresponding positioning hole II. A limiting nut is screwed to each of the two axial ends of the positioning rod. Two locking nuts are located at the far ends of the positioning blocks I and II, respectively. A fixing nut is provided between the positioning blocks I and II of the fixedly connected positioning plates. A fixing nut is also provided on the inner side of the adjacent support frame of the slidably connected positioning plates. The fixing nut is screwed to the corresponding positioning rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features two positioning plates on the underside of the support frame. One plate is fixed to an adjacent support frame, while the other is slidably connected to it, providing structural adjustability and allowing for flexible adaptation to different working conditions. The positioning plates are detachably connected to upper and lower axial limiting rods, which are inserted between adjacent support rollers with their upper surfaces higher than the rollers. This effectively limits the gauge baffle, preventing it from sliding back and forth on the support rollers, significantly improving the stability and precision of the gauge baffle processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Please see Figure 1 This paper demonstrates a V-shaped gauge baffle mechanical structure, whose design is consistent with existing technology. The structure comprises two rear-mounted support frames 2 and several support rollers 1 with their central axes horizontal. The support rollers 1 are rotatably connected to the support frames 2, and these support rollers 1 are arranged side-by-side and equidistantly between the two support frames 2. The main function of the support rollers 1 is to provide a stable support surface for the gauge baffle, ensuring its smooth placement and facilitating subsequent processing operations.

[0027] It should be noted that this device addresses the variation in centrifugal force caused by differences in curvature of the conveyor belt at bends, which in turn leads to uneven horizontal thrust of the gauge baffle. This uneven thrust could potentially cause displacement of the gauge baffle, affecting subsequent processing accuracy. According to relevant research, bending resistance increases with increasing pressing force and belt speed, and decreases with increasing tension and roller diameter. Furthermore, force analysis at bends reveals complex stress conditions on the conveyor belt, including centripetal force, frictional resistance, and impact force. The combined effect of these factors can lead to instability of the gauge baffle.

[0028] Please see Figure 1 and Figure 2 Unlike existing technology devices, this device has a positioning plate 6 below the support frame 2, and there are two positioning plates 6, which correspond to the two support frames 2 respectively.

[0029] In addition, one positioning plate 6 is fixedly connected to the adjacent support frame 2, while the other is slidably connected to the support frame 2. This design gives the entire structure a certain degree of adjustability.

[0030] Meanwhile, each positioning plate 6 is detachably connected to a vertically axially limiting rod 3. The limiting rod 3 is inserted between two adjacent support rollers 1, and the height of its upper end face is greater than the height of the upper end face of the support roller 1. The function of the limiting rod 3 is to limit the gauge baffle and prevent it from sliding back and forth on the support roller 1.

[0031] Furthermore, such as Figure 3As shown, the device has a through hole 13 on the positioning plate 6 for the limiting rod 3. The lower end of the limiting rod 3 is screwed to two locking nuts 7 through external threads. This allows the limiting rod 3 to be inserted through the through hole 13 on the positioning plate 6 and fixed by the two locking nuts 7 at the lower end, ensuring the stability of the position of the limiting rod 3.

[0032] Furthermore, a bearing 4 is coaxially fixedly connected to the upper end of the limiting rod 3, and a contact ring 5 is sleeved on the outside of the bearing 4. The contact ring 5 is rotatably connected to the limiting rod 3 through the bearing 4. When the gauge baffle contacts the contact ring 5, the contact ring 5 can rotate flexibly, effectively reducing the frictional resistance between the two, thereby facilitating the smooth movement and precise adjustment of the gauge baffle.

[0033] It is worth noting that in practical applications, the limiting rod 3 is detachably connected to the positioning plate 6 via the locking nut 7. This allows the size of the contact ring 5 to be adjusted according to actual needs (axial length of the support roller 1), such as... Figure 6 As shown, this ensures that the diameter of the contact ring 5 matches the arrangement density of the support roller 1, thus guaranteeing that the device can effectively constrain the gauge baffle.

[0034] Furthermore, the distance between the two positioning plates 6 in this device is designed to present a U-shaped curve, that is, the distance between the two ends of the two positioning plates 6 is greater than the distance between the middle sections. This makes the constraint effect of the device on the gauge baffle through the limiting rod 3 present a linear change. In practice, the position of the gauge baffle can be gradually adjusted to ensure that the position of all gauge baffles on the upper side of the support roller 1 can be fully adjusted.

[0035] Please see Figure 4 and Figure 5 To achieve a fixed connection between one positioning plate 6 and the support frame 2, and a sliding connection between the other positioning plate 6 and the support frame 2, this device provides a positioning block I 12 on the underside of each positioning plate 6, with a through positioning hole I on the positioning block I 12. Simultaneously, a positioning block II 10 is provided on the underside of each support frame 2, with a through positioning hole II on the positioning block II 10 corresponding to the positioning hole I. The positioning rod 9 is inserted into each corresponding positioning block I 12 and positioning block II 10, and then the limiting nuts 11 are tightened at both ends of the positioning rod 9.

[0036] Therefore, in this device, a fixing nut 14 is provided between the positioning block I 12 and the positioning block II 10 corresponding to the positioning plate 6 which is fixedly connected to the support frame 2. By constraining the fixing nut 14 to be screwed to the corresponding positioning rod 9, the position of the positioning plate 6 is fixed by the clamping action between the fixing nut 14 and the locking nut 7.

[0037] Accordingly, to achieve a sliding connection between the other positioning plate 6 and the support frame 2, this device only provides a fixing nut 14 on the inner side of the support frame 2 adjacent to the positioning plate 6 that is slidably connected to the support frame 2. At this time, by cooperating with the fixing nut 14 and the locking nut 7, the sliding connection between the positioning plate 6 and the support frame 2 can be easily achieved by simply fixing the position of the positioning rod 9.

[0038] It is worth noting that, in practical applications, the cooperation between the positioning rod 9 and the fixing nut 14 and the limiting nut 11 not only enables the positioning plate 6 and the support frame 2 to be detachably connected, but also ensures the consistency between the curvature of the positioning plate 6 and the curvature of the support frame 2, thereby accurately controlling the distance between the two ends of the positioning plates 6. Moreover, by adjusting the axial length of the positioning rod 9, the initial position of the positioning plate 6 and its sliding distance can be adjusted.

[0039] Please see Figure 4 and Figure 5 To ensure effective control of the distance between the two positioning plates 6 and to ensure that the position of the gauge baffle adjusted by the limit rod 3 meets expectations, this device is equipped with a drive mechanism 8 on one side of the positioning plate 6 that is slidably connected to the support frame 2.

[0040] The drive mechanism 8 includes a screw, which is rotatably connected to the adjacent support frame 2. A follower block 801 is screwed onto the middle section of the screw, and the follower block 801 is fixedly connected to the corresponding positioning plate 6. When the screw is rotated, the follower block 801 travels linearly along the screw, driving the fixedly connected positioning plate 6 to move linearly back and forth. In this way, the relative position between the two positioning plates 6 can be adjusted, thereby changing the position of the limit rod 3 to accommodate track gauge baffles of different track gauges.

[0041] In practical applications, this utility model is as follows:

[0042] Support base: Two arc-shaped support frames 2 with their central axes coincident are used, and support rollers 1 arranged at equal intervals on them provide a support plane for the track gauge baffle.

[0043] Positioning and Limiting: Two positioning plates 6 are located on the lower side of the support frame 2, one fixed and one sliding, with a U-shaped curve between them to accommodate different baffles. A limiting rod 3 is detachably connected to the positioning plate 6, inserted between the support rollers 1 and higher than the roller surface, and fixed to the locking nut 7 through the through hole 13. The contact ring 5 at the upper end of the limiting rod 3 can rotate by the bearing 4 to reduce friction with the baffle.

[0044] Drive adjustment: The drive mechanism 8 located on one side of the sliding positioning plate 6 drives the follower block 801 through the rotation of the screw, thereby driving the positioning plate 6 to move linearly, realizing the adjustment of the position of the limit rod 3 to adapt to diverse track gauge requirements.

[0045] Auxiliary positioning: The positioning plate 6 and the positioning block under the support frame 2 are further fixed by the positioning rod 9, the limit nut 11 and the fixing nut 14 to ensure structural stability.

[0046] During operation, the baffle is placed on the support roller 1, and the positioning plate 6 is adjusted according to its size by the drive mechanism 8 to limit the position of the limit rod 3, thus completing the support and positioning.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
