Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and specifically to a bogie stopping device, and more particularly to a thinner bogie stopping device. Background Technology

[0002] When bogies are circulating on the production line, they travel on I-beam tracks, and workers typically stop them by pushing them forward (workers need to place a stopper in advance in the direction the bogie is moving). This results in extremely high labor intensity for workers. Moreover, bogies often circulate one after another on the production line, requiring workers to anticipate when a bogie is about to stop and manually place a stopper on the track in front of it. When the bogie needs to continue circulating, the stopper must be manually removed immediately. This places high demands on the workers' timeliness, keeps them under high stress for extended periods, and increases the risk of errors under heavy workloads, potentially leading to serious collisions or injuries.

[0003] Stoppers are made of various materials: metal stoppers, commonly known as "iron shoes," are often used to prevent bogies from moving when stationary; rubber stoppers are the most commonly used, and are more often used on bogies that rotate frequently, providing better cushioning and anti-collision effects.

[0004] On some existing equipment, V-type limit mechanisms (V-type positioning blocks) are often used to stop bogies. However, V-type limit mechanisms are expensive and require pits to be made on both sides or under the track to install the corresponding large structure, which further increases the cost of civil engineering and occupies a certain amount of space. They are not very friendly to equipment or manual intervention operations.

[0005] In summary, the existing bogie stopping issues are summarized as follows: (1) Fatigue: Workers need to respond in a timely manner, which leads to high concentration and fatigue. (2) Poor safety: During manual operation, the production line is busy, and there may be situations such as the stop device not being placed in time or the bogie tilting after impact, which can easily cause accidents. The bottom power supply device is prone to contact with water, resulting in safety hazards such as leakage. (3) Poor positioning accuracy: When the stop device is placed manually, the placement position is relatively random, which makes it difficult to ensure repeatability and positioning accuracy, and is not suitable for equipment use; (4) High price: Some automated V-type limit mechanisms have relatively complex structures and require a lot of civil engineering work, resulting in higher overall costs; (5) Large space usage: Some equipment uses V-shaped positioning and limiting mechanisms, which have complex structures and need to be sunk into the pit, which takes up a lot of space and is not conducive to equipment and manual intervention. (6) Damage to the track: Some equipment uses positioning and limiting mechanisms that sometimes require cutting the track to avoid or install it, resulting in additional destructive construction. Summary of the Invention

[0006] In view of the shortcomings and defects of the existing technology, the purpose of this utility model is to provide a thinner bogie stopping device.

[0007] To achieve the above or other objectives, the technical solution of this utility model is as follows: A thin bogie stopping device is provided, located on the side of the bogie's forward track. The device includes a fixed base and a cover plate, forming a hollow cavity between them. A notch is provided on the side of the cover plate facing the track. The hollow cavity contains a fixed plate, a first ball bearing guide rail, a first cylinder, a second cylinder, a third ball bearing guide rail, a slide plate, a sliding slide plate, and a stop block. The fixed base has a fixed plate on it, with the first cylinder and the first ball bearing guide rail fixed perpendicular to the track direction. The top of the first ball bearing guide rail and the extended end of the first cylinder are fixedly connected to the slide plate. The slide plate has a second cylinder and the third ball bearing guide rail arranged along the track direction. The top of the third ball bearing guide rail and the extended end of the second cylinder are fixedly connected to the sliding slide plate. A stop block is provided inside the sliding slide plate to stop the bogie's wheelsets.

[0008] Furthermore, the height of the device is 50-70mm.

[0009] Furthermore, the stop is made of rubber.

[0010] Furthermore, the stop block is detachably installed in the slot of the sliding plate.

[0011] Furthermore, the slot of the fixing plate also fixes the cylinder limiting component to prevent the protruding end of the first cylinder from extending out of the track.

[0012] Furthermore, a first cable chain fixing plate is fixed in the designated groove on the lower side of the fixing plate by screws, and a second cable chain fixing plate is fixed in the groove of the slide plate. A cable chain is connected between the first cable chain fixing plate and the second cable chain fixing plate.

[0013] Furthermore, two parallel ball bearing guides are fixed to the fixed plate by screws, which together support the slide plate.

[0014] Furthermore, two sets of parallel third ball bearing guides are fixed to the slide plate with screws to jointly support the sliding slide plate.

[0015] Furthermore, the fixed base is bolted or pre-embedded in a cement foundation on the side of the bogie's forward track.

[0016] The technical ideas in the design process of this utility model device include the following: Based on the existing bogie stopping requirements, this utility model first considers the frequent need for mobile stopping operations of bogies on maintenance lines, and selects rubber material with good buffering performance as the stopping contact material; secondly, for bogies weighing more than 6 tons, if rubber is used, its lifespan will be slightly shorter, so the quick replacement of rubber should be fully considered. Specifically, in this utility model, the stop block should be easy to replace.

[0017] Similarly, priority should be given to minimizing or eliminating civil engineering work to reduce unnecessary expenses and construction time. At the same time, given the limited space under the bogie, the impact of the device's height should be fully considered. While ensuring performance, the height of this utility model device should be reduced to the greatest extent possible, minimizing the ground footprint and reducing the impact on manual intervention operations.

[0018] Since the bogie's forward direction is unsuitable for placing a mechanism, the stopping mechanism can only be placed on the side of the track. (When the bogie impacts the stopper, the conventional practice is to promptly place another stopper behind the bogie wheelset to effectively prevent the bogie from moving forward or backward, thus creating a stable positioning. However, in actual operation, due to the bogie's large mass and kinetic energy, it may return after impacting the front stopper. Workers may place the rear stopper at an uncertain time, resulting in inaccurate positioning and situations where the bogie wheelset tread and the stopper's inclined surface are tightly fitted. In such cases, if the stopper is automatically moved away from the side, significant resistance may occur.) This invention ensures the reliability of the action by first disengaging from the tread and then moving laterally (specifically, the rubber stopper first leaves the wheelset tread along the bogie's forward direction and then retracts into the device perpendicular to the track direction).

[0019] Considering the ground contact device, this utility model should fully take into account the impact of water, ash and other equipment on stability and safety, and should give priority to using pneumatic components as the power source.

[0020] Considering factors such as cost, this utility model should avoid unnecessary cost inputs as much as possible, such as civil engineering, cutting tracks and other additional cost items.

[0021] Specifically, compared with the prior art, the thinner bogie stopping device of this utility model has the following advantages: (1) Reduce personnel fatigue: This utility model device replaces manual stopping operations, frees up labor, avoids constantly paying attention to the bogie status, and avoids maintaining a high level of tension at all times, thus greatly reducing fatigue intensity.

[0022] (2) Improved personnel safety: This utility model device replaces manual stopping operations and uses an air source as the power source for the ground-attached device, eliminating the safety hazards of water leakage and electric shock, thus greatly improving safety.

[0023] (3) Stable positioning and high precision: Due to the use of automated operation, the stability of this utility model device is much higher than that of the manual stop device, and it is not easy to make mistakes (it uses a fixed position limit, which is not as large as the deviation of manual placement, and the relative precision is relatively high).

[0024] (4) Extremely low cost: This utility model does not require the space under the track, does not require a separate civil engineering pit, and has a simple structure and low cost.

[0025] (5) Small space occupation: This utility model adopts a thin design with a height of 50-70mm, and does not occupy underground space, etc. The structure is small and the overall space occupation is small.

[0026] (6) It does not affect other facilities: This utility model does not require damage to existing facilities such as tracks; it can be used directly by simply installing this device.

[0027] (7) Simple installation: This utility model can be installed on the side of the track, and can be installed by chemical bolts or simply pre-embedded in the cement foundation. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 As shown, the bogie 3 is on the I-shaped track 2. In this embodiment, the stopping device 1 is placed on the front side of the bogie 3 in the forward direction. During operation, the stopping device 1 extends the rubber block 5 to the front of the front wheel of the bogie 3. At this time, the wheel tread 4 of the bogie 3 contacts the rubber block 5, which produces a blocking and buffering effect.

[0031] Reference Figures 3 to 5 As shown, the stopping device 1 in this embodiment includes a fixed base 6, a fixed plate 7, a first ball bearing guide rail 9, a first cylinder 12, a second cylinder 15, a second ball bearing guide rail 18, a third ball bearing guide rail 21, a slide plate 22, a sliding slide plate 23, and a cover plate 25.

[0032] The fixed base 6 is equipped with a cover plate 25, forming a hollow cavity between the cover plate 25 and the fixed base 6. This cavity is used to house structures such as the first cylinder 12 and the second cylinder 15. A first warning sign 13 and a second warning sign 24 are affixed to the upper surface of the cover plate 25. A notch is provided on the side of the cover plate 2 facing the I-shaped track 2 to facilitate the extension of the rubber stop block 5.

[0033] A fixing plate 7 is fixed to the fixed base 6 by screws.

[0034] A first cylinder 12 is fixed to one side of the fixed plate 7 (the first cylinder 12 is on the fixed plate 7). The first cylinder 12 is set in a direction perpendicular to the forward direction of the bogie 3. The extended end of the first cylinder 12 is fixedly connected to the slide plate 22 through the angle connector 8. Quick connectors 11 are installed at the two air ports of the first cylinder 12.

[0035] Preferably, the slot of the fixing plate 7 also fixes the cylinder limiting member 10 to prevent the extended end of the first cylinder 12 from extending out of the I-shaped track 2.

[0036] The first ball bearing guide 9 and the second ball bearing guide 18 are fixed on the fixed plate 7. The first ball bearing guide 9 and the second ball bearing guide 18 are parallel to each other and their setting direction is perpendicular to the forward direction of the bogie 3. The first ball bearing guide 9 and the second ball bearing guide 18 are mounted on the slide plate 22 by screws.

[0037] A first drag chain fixing plate 17 is fixed in the designated groove on the lower side of the fixing plate 7 by screws, and a second drag chain fixing plate 20 is fixed in the groove of the slide plate 22. One end of the drag chain 19 is connected to the first drag chain fixing plate 17, and the other end of the drag chain 19 is connected to the second drag chain fixing plate 20.

[0038] The tail end of the second cylinder fixing plate 14 is fixed to the slide plate 22 by screws. The second cylinder 15 is fixed to the lower end of the other end of the second cylinder fixing plate 14 by screws. The setting direction of the second cylinder 15 is consistent with the forward or backward direction of the bogie 3. The protruding end of the second cylinder 15 is connected to the sliding slide plate 23. A rubber stop 5 is detachably installed in the slot on the sliding slide plate 23. When it is necessary to replace the rubber stop 5, simply remove the tightening screw on the side of the sliding slide plate 23 to lift the rubber stop 5 out of the slot of the sliding slide plate 23 (e.g., Figure 4 and Figure 5 The images show the rubber stop 5 and the sliding plate 23 in their disassembled and installed states, respectively. A second cylinder connector 16 is installed at each of the two air ports of the second cylinder 15.

[0039] Two sets of parallel third ball bearing guides 21 are fixed on the slide plate 22 by screws. The direction of the third ball bearing guides 21 is consistent with the forward or backward direction of the bogie 3. A sliding plate 23 is fixed above the third ball bearing guides 21 by screws.

[0040] The movement process of the stopping device 1 in this embodiment is as follows: When a limit instruction is given: The telescopic end of the first cylinder 12 extends, pushing the slide plate 22 to move in the telescopic direction of the first cylinder 12 (perpendicular to the forward direction of the bogie 3). The sliding slide 23 moves with the slide plate 22 and drives the rubber stop 5 to extend out from the cover plate 25. Then, the telescopic end of the second cylinder 15 extends, pushing the sliding slide 23 to move in the telescopic direction of the second cylinder 15 (the backward direction of the bogie 3). The rubber stop 5 moves along the I-shaped track 2 outside the cover plate 25, waiting for material. Finally, the rubber stop 5 contacts the wheel tread surface 4 of the bogie 3, producing a blocking and buffering effect.

[0041] After giving the exit command: The second cylinder 15 drives the sliding slide 23 and its rubber stop 5 to retract; then the first cylinder 12 retracts, driving the slide plate 22 and its sliding slide 23 and its rubber stop 5 to retract into the cover plate 25, completing the exit action.

[0042] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model. Technologies not covered by this utility model can be implemented by existing technologies.
