Description

Technical Field

[0001] This utility model belongs to the technical field of bogie transport devices, and relates to a bogie transport device, specifically a bogie roller transport mechanism. Background Technology

[0002] In bogie maintenance, especially when performing automated maintenance, it is often necessary to transport the bogies to facilitate automated operation of the entire equipment.

[0003] Currently, most depots rely on manual pushing of bogies, with limit blocks for positioning. The disadvantages are: extremely high labor intensity, as bogies are moved one after another along the production line, increasing the risk of collisions and even injuries to workers.

[0004] Currently, few depots utilize automated transport bogies. Transport methods include integral lifting and transport, and lever-driven wheel axle transport. In integral lifting, the bogie is lifted off the existing track and its horizontal movement to the designated position is controlled by a servo system. This method requires sophisticated equipment with high power and inertia, leading to numerous problems. Lever-driven wheel axle transport involves raising the lever and dragging the entire bogie forward from the axle's position. This method can only move the bogie towards the track direction, lacks timely stopping capabilities, and cannot achieve precise positioning.

[0005] In summary, the existing methods for transport bogies have the following problems:

[0006] (1) High labor intensity: Manual pushing of bogies is a high-intensity physical labor that can easily cause fatigue.

[0007] (2) Poor safety: When manually pushing, due to its large mass (the bogie weighs more than 6 tons), coupled with the busy work on the production line, personnel need to shuttle through the track work area, which can easily cause uncontrollable accidents.

[0008] (3) High power: The overall lifting and transport method will result in a large load and high power consumption.

[0009] (4) Poor positioning accuracy: Most of them cannot achieve high-precision rapid stop positioning and cannot meet the positioning accuracy requirements.

[0010] (5) Large inertial impact: The bogie has a large mass and the inertia has a large impact on the equipment, which can easily cause unnecessary impact damage to the transport equipment and transported objects. Summary of the Invention

[0011] The purpose of this utility model is to provide a bogie roller transport mechanism to address the thorny problems in existing bogie transportation.

[0012] First, the rigid requirements for later automated precise positioning should be met;

[0013] Secondly, consider the issue of mobile transportation:

[0014] For bogies weighing over 6 tons, if the entire bogie is lifted and transported, the structural stability requirements are relatively high, and the transport mechanism itself will inevitably be bulky, which can easily lead to obvious disadvantages such as high power consumption, large footprint, and increased design requirements.

[0015] This invention prioritizes servo-driven transport based on automation requirements. Secondly, it employs on-rail transport (not off-rail). Then, considering the characteristics of various bogie structures (rail spacing of 1435mm, wheel diameters of 840mm and 915mm are common specifications, including some wheel diameters involving wheel manufacturing processes; given their relatively standardized dimensions, controllable deviations, and easier access to a towing mechanism compared to other locations), the four wheels are the preferred towing position. Considering structural volume, this invention uses a towing mechanism that pulls one of the four wheels for traction. This invention avoids the problem of a bulky and heavy structure in overall lifting transport, while also avoiding unnecessary power consumption and the need for lifting mechanisms under large loads, and ensuring high positioning accuracy.

[0016] The technical solution adopted by this utility model to solve its technical problem is:

[0017] A bogie roller transport mechanism is disclosed, wherein the bogie is mounted on an overhead track. The bogie roller transport mechanism includes a servo slide and a roller structure mounted on the servo slide. The servo slide drives the roller structure to move below the bogie via servo transmission. The roller structure includes a rotating wheel, a rotating arm, a limiting end cap, a rotating platform, a guide rail, a cylinder, a bracket, and a sliding plate. The guide rail is mounted on the bracket along the track direction, and the sliding plate is vertically connected to the guide rail. The two sliding plates are respectively connected to the rotating platform by two rotating arms through the limiting end cap. The lower part of the rotating platform is connected to the cylinder. A rotating wheel is provided at the outer end of the sliding plate. The two rotating wheels move towards each other to clamp and lift one wheel of the bogie.

[0018] Furthermore, the servo slide includes a slide base, a first rack, a first servo geared motor, and a first slide plate; the slide base is fixed below the overhead track, and the first rack is arranged on the slide base along the track direction. The first rack is connected to the first servo geared motor, and the first servo geared motor is mounted on the first slide plate, driving the first rack to drive the first slide plate to move along the track direction.

[0019] Furthermore, a first ball linear guide is installed on the slide base along the track direction, and the first slide plate is fixedly connected above the first ball linear guide.

[0020] Furthermore, the servo slide also includes a second rack, a second slide plate, and a second servo geared motor; the second rack is arranged on the first slide plate and perpendicular to the track direction, the second rack is connected to the second servo geared motor, the second servo geared motor is mounted on the second slide plate, and drives the second rack to drive the second slide plate to move perpendicular to the track direction.

[0021] Furthermore, a second ball linear guide is installed on the first slide plate and perpendicular to the track direction, and the second slide plate is fixedly connected above the second ball linear guide.

[0022] Furthermore, the bottom of the support roller structure is fixedly connected to the second slide plate.

[0023] Furthermore, the middle part of the cylinder connecting rod is connected below the rotary table, and the two ends of the cylinder connecting rod are respectively connected to cylinders.

[0024] Furthermore, an adjustable adapter plate is installed on the outer end of the skateboard, which can be easily adjusted in terms of the extended length through a multi-hole structure, and the wheel is installed on the adjustable adapter plate.

[0025] Furthermore, when the wheel clamps the bogie wheel, the wheel rotates to avoid sliding friction.

[0026] Furthermore, the upper part of the rotary table is configured in a "Z" shape.

[0027] The advantages of this utility model are as follows:

[0028] (1) The bogie support roller transport mechanism of this utility model reduces labor intensity: it replaces manual pushing of the bogie, liberates labor force, and completely releases manpower.

[0029] (2) The safety of personnel is improved by using the bogie support roller transport mechanism of this utility model: due to the use of machine operation, the safety is greatly improved.

[0030] (3) The bogie support roller transport mechanism of this utility model has low energy consumption: it adopts a non-derailment method, avoids the overall lifting and transport method, and only provides forward kinetic energy consumption. The energy consumption is reasonable, the utilization rate is high, and the energy consumption is relatively low.

[0031] (4) The bogie support roller transport mechanism of this utility model can ensure high precision. The use of dedicated servo transmission can ensure relatively high precision and meet most automation requirements.

[0032] (5) The bogie support roller transport mechanism of this utility model reduces inertial damage: Since the transport is carried out by lifting a single wheel from the bottom, the servo can be selected to accelerate or decelerate as needed to meet the requirements of stopping and starting immediately, thus avoiding large impact forces. At the same time, even in the event of an emergency, due to the working characteristics of the bottom of the support roller, the center of gravity of the wheel is higher than the limit position of the support roller. After its forward direction is blocked, the impact force will be guided upward, which has excellent unloading ability and outstanding safety protection function. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] The bogie support roller transport mechanism of this embodiment includes a servo slide 6 and a support roller structure 2. The support roller structure 2 is installed on the servo slide 6. The servo slide 6 drives the support roller structure 2 to run to a designated position. The support roller structure 2 clamps and lifts one of the wheels of the bogie 1 and moves it to the required position.

[0040] Among them, such as Figure 2As shown, the servo slide 6 includes a slide base 7, a first rack 8, a first ball linear guide 9, a first servo geared motor 12, and a first slide plate 13. The slide base 7 is fixed below the first track 3 and the second track 4. The first rack 8 is arranged on the slide base 7 and along the track direction. The first rack 8 is connected to the first servo geared motor 12 (the first servo geared motor 12 is mounted on the first slide plate 13), which drives the first rack 8 to drive the first slide plate 13 to move along the track direction.

[0041] To facilitate smoother movement, a first ball linear guide 9 is installed on the slide base 7 along the track direction, and a first slide plate 13 is fixedly connected above the first ball linear guide 9.

[0042] Preferably, the servo slide 6 further includes a second rack 10, a second slide plate 14, and a second servo geared motor 15; the second rack 10 is arranged on the first slide plate 13 and perpendicular to the track direction, the second rack 10 is connected to the second servo geared motor 15 (the second servo geared motor 15 is mounted on the second slide plate 14), driving the second rack 10 to drive the second slide plate 14 to move perpendicular to the track direction.

[0043] To facilitate smoother movement, a second ball linear guide 11 is installed on the first slide plate 13 and perpendicular to the track direction, and a second slide plate 14 is fixedly connected above the second ball linear guide 11.

[0044] The roller support structure 2 is mounted on the second slide plate 14. The servo slide 6 drives the roller support structure 2 to a designated position, clamps and lifts one wheel of the bogie 1, and moves it to the required position.

[0045] Among them, such as Figure 3 and Figure 4 As shown, the roller structure 2 includes a rotating wheel 16, a rotating arm 17, a limiting end cover 18, a rotating table 19, a third ball linear guide rail 21, a cylinder 22, a bracket 23, and a sliding plate 25.

[0046] A third ball linear guide 21 is set on the bracket 23 along the track direction. A slide plate 25 is vertically connected to the third ball linear guide 21. The two slide plates 25 are respectively connected to the rotary table 19 by two rotating arms 17 through the limiting end cap 18. The lower part of the rotary table 19 is placed in the hole of the bracket 23 and connected to the cylinder 22. A rotating wheel 16 is installed on the outer end of the slide plate 25. The two rotating wheels 16 clamp one wheel of the bogie 1 at the same time.

[0047] Preferably, when the wheel 16 clamps the wheel of the bogie 1, the wheel 16 and the wheel rim of the bogie 1 are in contact, and the wheel 16 rotates to avoid sliding friction.

[0048] Preferably, the middle part of the cylinder connecting rod 24 is connected below the rotary table 19, and the two ends of the cylinder connecting rod 24 are respectively connected to the cylinder 22.

[0049] Preferably, an adjustable adapter plate 20 is installed on the outer end of the skateboard 25. The extended length is easily adjusted through a multi-hole connection. A wheel 16 is installed on the adjustable adapter plate 20.

[0050] The bogie roller transport mechanism in this embodiment is mainly used in elevated track operation, in conjunction with the servo slide 6. The roller transport process is as follows:

[0051] First, the first slide plate 13 of the servo slide 6 drives the roller support structure 2 to move to the position directly below the wheel of the bogie 1;

[0052] Then, the second slide plate 14 on the servo slide 6 drags the roller structure 2 to move the position of the gap below the wheel;

[0053] Finally, the roller support structure 2 tightens the rotating arm 17, and the wheel is clamped and raised into the air. At this time, the servo slide 6 can drag the bogie 1 to a designated position as needed.

[0054] Specifically, the process of using the support roller structure 2 to lift one wheel of the bogie 1 is as follows:

[0055] When cylinder 22 retracts, cylinder 22 drives cylinder connecting rod 24, causing rotary table 19 to rotate, which in turn drives upper rotating arm 17. The two rotating arms 17 drive two slide plates 25 to run symmetrically towards each other on the third ball linear guide rail 21. The adjustable connecting plate 20 and rotating wheel 16 on the two slide plates 25 also run symmetrically towards each other. The distance between the two rotating wheels 16 decreases, and one wheel of bogie 1 will be lifted as a result, which plays a supporting role. Conversely, the wheel of bogie 1 will be lowered.

[0056] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the claims of the present utility model.
