[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0027] The following is combined Figures 1-9 The present invention describes a rail drive device.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a rail-mounted drive device 1 for traveling along a track 2. The track 2 includes a toothed rail 21 and a support rail 22 arranged parallel to the toothed rail 21. The rail-mounted drive device 1 includes a vehicle body 11, a first frame 12, a second frame 13, and a drive device 14. The first frame 12 and the second frame 13 are rotatably mounted on the bottom of the vehicle body 11 about a vertical axis. The first frame 12 and the second frame 13 are arranged at intervals along the front-rear direction of the vehicle body 11 and are used to move along the support rail 22. The drive device 14 is disposed on the vehicle body 11 and is used to mesh with the toothed rail 21 and drive the vehicle body 11 to move along the track 2.

[0029] In this embodiment, the vehicle body 11 is the main structure of the rail-driven equipment 1, which can be used to transport personnel or goods along the track 2. The track 2 includes a rack rail 21 and a support rail 22 arranged side by side. The rack rail 21 is used to cooperate with the drive device 14 on the vehicle body 11 to provide power for the vehicle body 11 to travel along the track 2. The support rail 22 is used to cooperate with the first frame 12 and the second frame 13 at the bottom of the vehicle body 11 to provide support and guidance for the vehicle body 11.

[0030] In this embodiment, the first frame 12 and the second frame 13 are arranged at intervals along the front-rear direction of the vehicle body 11 at the bottom of the vehicle body 11, and the first frame 12 and the second frame 13 can rotate relative to the vehicle body 11 around the vertical axis respectively, so as to reduce the rotation angle of the vehicle body 11 when cornering, and make the entire rail drive equipment 1 have better passing performance when facing small radius curves.

[0031] Understandably, when a conventional rigid vehicle with four drive wheels passes through a curve with a large arc and small radius, it may get stuck or even derail because the two front wheels are in the middle of the curve while the two rear wheels are still on the straight and cannot turn with the front wheels.

[0032] In this embodiment, when the rail-driven equipment 1 passes through a curve, both the first frame 12 located at the front of the vehicle body 11 and the second frame 13 located at the rear of the vehicle body 11 can rotate flexibly relative to the vehicle body 11 around the vertical axis, which can effectively avoid the situation where the rigid vehicle cannot pass through a small radius curve smoothly.

[0033] The rail-mounted drive equipment 1 of the present invention, by providing a drive device 14 adapted to the toothed rail 21 on the car body 11, the drive device 14 can mesh with the toothed rail 21 to provide driving power to the car body 11, so that the rail-mounted drive equipment 1 can travel along the rail 2. At the same time, by providing a first frame 12 and a second frame 13 at the bottom of the car body 11 that can rotate relative to the car body 11 and are spaced apart along the front and rear direction of the car body 11, the first frame 12 and the second frame 13 can cooperate with the support rail 22 to provide support and guidance for the car body 11. When turning, the first frame 12 and the second frame 13 can rotate flexibly relative to the car body 11 to prevent the rail-mounted drive equipment 1 from getting stuck when passing through small radius curves, the passability of the rail-mounted drive equipment 1 when facing curves is effectively improved, and the problem of poor curve passing performance of existing rail vehicles and inability to adapt to the winding and narrow working environment in underground mines is solved.

[0034] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, there are two load-bearing rails 22, and a toothed rail 21 is located between the two load-bearing rails 22. The first frame 12 and the second frame 13 both include a rotating frame 121 and two roller assemblies 122. The rotating frame 121 is located at the bottom of the vehicle body 11 and is rotatably connected to the vehicle body 11 around a vertical axis. The two roller assemblies 122 are spaced apart on the rotating frame 121 and are arranged in a one-to-one correspondence with the two load-bearing rails 22. The roller assemblies 122 are adapted to make rolling contact with the load-bearing rails 22.

[0035] In this embodiment, the rotating frame 121 is rotatably disposed at the bottom of the vehicle body 11 so that the rotating frame 121 and the roller assembly 122 on the rotating frame 121 can rotate relative to the vehicle body 11 about a vertical axis. Exemplarily, the rotating frame 121 may include a bracket and a rotating shaft, wherein the rotating shaft extends vertically, its upper end can be connected to the vehicle body 11, and its lower end is inserted into the shaft hole of the bracket, allowing the bracket to rotate about the rotating shaft.

[0036] In addition, by setting two support rails 22 and setting two roller assemblies 122 on the rotating frame 121 that correspond one-to-one with the support rails 22, the two roller assemblies 122 can contact the corresponding support rails 22 and roll along the support rails 22. This arrangement makes the force on the vehicle body 11 more balanced and more stable and reliable during driving.

[0037] Specifically, in some embodiments, such as Figure 2 , Figure 6 and Figure 9 As shown, each roller assembly 122 includes: a wheel seat 1221, a first roller 1222, and a second roller 1223; the wheel seat 1221 is disposed at the bottom of the rotating frame 121; the first roller 1222 is rotatably disposed on the wheel seat 1221, the axis of the first roller 1222 extends in the horizontal direction, and the first roller 1222 is used to roll contact with the top surface of the support rail 22; the second roller 1223 is rotatably disposed on the wheel seat 1221, the axis of the second roller 1223 is set at an angle to the horizontal direction, and the second roller 1223 is used to roll contact with the side of the support rail 22.

[0038] In this embodiment, the wheel seat 1221 is fixedly connected to the rotating frame 121 and is used to mount the rollers. The first roller 1222 can roll along the top surface of the support rail 22 around a horizontal axis to support the wheel seat 1221, the rotating frame 121, and the vehicle body 11, and to enable the rail-clamping drive equipment 1 to move along the track 2. The axis of the second roller 1223 is angled to the horizontal direction; for example, it can be perpendicular to or inclined to the horizontal plane, so that the rim of the second roller 1223 can roll into contact with the side of the support rail 22. This limits and guides the relative position of the roller assembly 122 and the support rail 22 in the left-right direction when the first roller 1222 rolls along the top surface of the support rail 22, thereby guiding the movement direction of the rotating frame 121 and the entire rail-clamping drive equipment 1, so that the first frame 12 and the second frame 13 can move more smoothly along the support rail 22.

[0039] In some embodiments, such as Figure 2 and Figure 6 As shown, the support rail 22 includes a first part 221 and a second part 222, wherein the first part 221 extends in a vertical direction; the second part 222 extends in a horizontal direction and is perpendicularly connected to the first part 221; the first roller 1222 is used to roll contact with the top surface of the second part 222 of the corresponding support rail 22; the second roller 1223 is inclined relative to the horizontal direction so as to roll contact with the side of the first part 221 of the corresponding support rail 22 away from the toothed rail 21 and / or the bottom side of the second part 222.

[0040] In this embodiment, the support rail 22 is composed of a first part 221 and a second part 222 that are perpendicular to each other, so that the cross-section of the support rail 22 is approximately "T" shaped. The top of the "T" shaped rail (i.e., the top surface of the second part 222) can be used for the first roller 1222 to roll. In this embodiment, the second roller 1223 is located on the side of the support rail 22 opposite to the toothed rail 21, so that the two support rails 22 can be clamped between the second rollers 1223 of the two roller assemblies 122 on the same rotating frame 121. The two second rollers 1223 can guide and limit the first frame 12 and the second frame 13 and the support rail 22, so that the first frame 12 and the second frame 13 can move more smoothly along the support rail 22 and prevent the first frame 12 and the second frame 13 from separating from the support rail 22.

[0041] Meanwhile, since the second roller 1223 is tilted in this embodiment, the side of the second roller 1223 facing the corresponding bearing rail 22 can extend obliquely upward, so that the rim of the second roller 1223 can roll into contact with the side of the first part 221 and the bottom surface of the second part 222, so as to cooperate with the first roller 1222 to guide and limit the frame and the bearing rail 22 in the two vertical directions of the lateral and longitudinal directions.

[0042] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the drive device 14 includes a drive disk assembly 141 and a drive assembly 142. The drive disk assembly 141 is rotatably disposed on the vehicle body 11 and is adapted to mesh with the gear rail 21. The drive assembly 142 is disposed on the vehicle body 11 and is connected to the drive disk assembly 141 in a transmission manner to drive the drive disk assembly 141 to rotate relative to the vehicle body 11.

[0043] In this embodiment, the drive disk assembly 141 is generally disc-shaped and can rotate relative to the vehicle body 11. The edge of the drive disk assembly 141 is provided with a meshing mechanism that can engage with the toothed rail 21. During the rotation of the drive disk assembly 141, the edge structure of the drive disk assembly 141 can sequentially mesh with the toothed rail 21 to generate a thrust on the vehicle body 11, thereby causing the vehicle body 11 to move forward or backward along the track 2. The drive assembly 142 is used as a power source to drive the drive disk assembly 141 to move relative to the vehicle body 11. It can be understood that by controlling the rotation direction of the drive disk assembly 141, the movement direction of the vehicle body 11 relative to the track 2 can be controlled.

[0044] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the drive disk assembly 141 includes: two disk bodies 1411 and a plurality of connecting shafts 1412; the disk bodies 1411 are rotatably disposed on the vehicle body 11, and the two disk bodies 1411 are disposed opposite to each other; the drive assembly 142 is drivenly connected to at least one of the disk bodies 1411; the plurality of connecting shafts 1412 are disposed between the two disk bodies 1411 and are respectively connected to the two disk bodies 1411; the plurality of connecting shafts 1412 are arranged at circumferential intervals along the two disk bodies 1411 for meshing with the gear rail 21.

[0045] In this embodiment, both disks 1411 are disc-shaped and are spaced apart from each other. The two disks 1411 are connected by connecting shafts 1412 arranged around their edges to form a single integrated structure. The drive assembly 142 is connected to either disk 1411 or both disks simultaneously to drive the drive disk assembly 141 to rotate. During the rotation of the disks 1411, the multiple connecting shafts 1412 between the disks 1411 can rotate sequentially into the tooth grooves of the gear rail 21, thereby connecting with the gear rail 21. 1. The two discs mesh with each other, and the contact between the connecting shaft 1412 and the toothed rail 21 generates a thrust on the vehicle body 11. At the same time, it can be understood that since the two discs 1411 are spaced apart, there is a certain space near each connecting shaft 1412. This structure allows the connecting shaft 1412 to move sequentially into the tooth groove of the toothed rail 21 when the drive disc assembly 141 enters the turning section of the toothed rail 21, and guides the drive disc assembly 141 and the vehicle body 11 to gradually turn along the turning section of the toothed rail 21, preventing the drive disc assembly 141 from jamming or disengaging from the toothed rail 21 when turning.

[0046] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, there are two drive components 142, which are connected to the two discs 1411 in a one-to-one transmission manner. In this embodiment, by providing two drive components 142, the two drive components 142 can provide power to the two discs 1411 respectively, making the force on the drive disc assembly 141 more balanced and the movement more stable and reliable.

[0047] In one specific embodiment, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the two drive components 142 and the drive disk assembly 141 (two disk bodies 1411 and connecting shaft 1412) are all arranged symmetrically about the central axis of the vehicle body 11.

[0048] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the drive assembly 142 includes a traction motor 1421 and a gearbox 1422. The output end of the traction motor 1421 is connected to the input end of the gearbox 1422, and the output end of the gearbox 1422 is connected to the drive disk assembly 141.

[0049] In this embodiment, the traction motor 1421 is used to input power to the gearbox 1422, drive the gear set inside the gearbox 1422 to rotate, and adjust the speed and torque of the drive disc assembly 141 through the transmission between multiple gear sets. This can convert the high speed and low torque of the traction motor 1421 into the low speed and high torque required by the drive disc assembly 141, so that the drive disc assembly 141 can have a certain climbing ability.

[0050] In one specific embodiment, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the gearbox 1422 is bolted to the vehicle body 11. The traction motor 1421 is bolted to the flange of the gearbox 1422. The motor shaft of the traction motor 1421 is connected to a coupling inside the gearbox 1422 via a key. The output shaft of the gearbox 1422, along with the coupling, is rigidly connected to the disc body 1411 via bolts. Multiple connecting shafts 1412 are mounted in bushings on the edge of the disc body 1411 with clearance fit.

[0051] In some embodiments, such as Figure 2 and Figure 4 As shown, the rail drive equipment 1 also includes a braking device 15, which is disposed on the vehicle body 11 and is used to lock or release the drive disc assembly 141.

[0052] In this embodiment, by providing a braking device 15 on the vehicle body 11, the braking device 15 can be used to lock the drive disc assembly 141, so that the drive disc assembly 141 is fixed relative to the vehicle body 11 (cannot rotate), thereby allowing the rail-clamping drive equipment 1 to stop on the rail 2 and prevent the vehicle from slipping.

[0053] Specifically, in some embodiments, the braking device 15 includes a brake caliper for clamping or releasing the drive disc assembly 141. In this embodiment, the brake caliper can clamp the drive disc assembly 141 to generate frictional braking force, causing the drive disc assembly 141 to decelerate smoothly until it stops rotating, thereby achieving parking.

[0054] In practical applications, when the rail-mounted drive equipment 1 is going downhill or needs to stop, the traction motor 1421 can be started first to make the drive disc assembly 141 flip for electric braking. If the electric braking torque is insufficient, the brake caliper is controlled to clamp the disc body 1411 to generate friction braking force, so that the rail-mounted drive equipment 1 can decelerate smoothly and park reliably to prevent the car from slipping.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
