Description

[0001] This application claims priority to the invention patent application filed with the Chinese Patent Office on July 31, 2024, with application number 202411040400.5 and invention title "Incline Track Transport Vehicle". Technical Field

[0002] This application belongs to the field of tunnel engineering equipment technology, specifically relating to an inclined tunnel track transport drive mechanism and an inclined tunnel track transport vehicle. Background Technology

[0003] The existing inclined shaft rail transport vehicle consists of a drive vehicle, a power vehicle, a traction rod, and a load-bearing pallet. The drive vehicle provides driving force, the power vehicle provides power source, and the loaded goods are placed on the load-bearing pallet. All the above components are connected into a whole by the traction rod to realize the inclined shaft transport of goods or items.

[0004] like Figure 1 and Figure 2 The prior art shown in the first example uses multiple independent drive vehicles, which has the following shortcomings:

[0005] When there are many drive cars, the overall length of the inclined shaft rail transport vehicle will increase, affecting the flexibility of its use. Since the height of the drive car is higher than the height of the pallet, placing the pallet between two drive cars is not conducive to loading, unloading and transferring goods in low spaces. The drive car is connected to the pallet via a towing rod. Due to its light weight, when the inclined shaft rail transport vehicle brakes suddenly downhill, the friction wheel and the intermediate rail will wear out in order to resist the overturning moment generated by the inertia of the pallet.

[0006] For example Figure 3 and Figure 4 In the prior art shown in the second example, although the drive vehicle is arranged at the bottom of the support plate, reducing the overall length of the inclined roadway rail transport vehicle, the arrangement of the drive vehicle makes turning inconvenient and requires too large a radius of curvature, making it unsuitable for complex small-radius turning roadways in coal mines.

[0043] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0047] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0048] like Figures 5 to 7 As shown, the first aspect of this application provides a inclined track transport drive mechanism, which is loaded with a support pallet 4 and includes: a drive vehicle 2; an axle 5, which is rotatably connected to the top of the drive vehicle 2 to form a vertical slewing pair; the drive vehicle 2 and the support pallet 4 are connected by the axle 5, and the axle 5 and the support pallet 4 are rotatably connected to form a horizontal slewing pair; and a motor reducer, which is horizontally arranged on the drive vehicle 2.

[0049] By placing the drive vehicle 2 at the bottom of the carrying pallet 4, it does not occupy effective space, shortening the length of the inclined shaft rail transport drive mechanism and the inclined shaft rail transport vehicle, and also does not obstruct the loading, unloading, and transfer of goods in low-ceilinged spaces. The drive vehicle 2 is connected to the carrying pallet 4 via a slewing joint, enabling the inclined shaft rail transport vehicle to complete horizontal and vertical turns with small radii. Furthermore, the use of a motor-reducer drive system, with the motor-reducer positioned below the lower plane of the carrying pallet 4, is suitable for working conditions where there are restrictions or requirements on the upper plane of the carrying pallet 4, and is more conducive to loading and transferring goods in low and confined spaces.

[0050] In some embodiments of this application, a slewing shaft is provided at the bottom of the support plate 4. The slewing shaft is inserted into the center hole of the axle 5 and locked in place. The top surface of the axle 5 is in contact with the bottom surface of the support plate 4. The support plate 4 is adapted to make horizontal circular motion around the slewing shaft to form a horizontal slewing pair. When the inclined shaft rail transport vehicle makes a horizontal turn, the slewing pair allows the support plate 4 to rotate flexibly relative to the drive vehicle 2, thereby reducing the overturning moment caused by changes in track curvature. This design helps maintain the stability of the inclined shaft rail transport vehicle, especially in the case of sudden stops or downhill, preventing the inclined shaft rail transport vehicle from overturning or jumping. The introduction of the horizontal slewing pair makes the entire transport system more flexible, stable, and durable, thereby improving the overall performance of the inclined shaft rail transport vehicle and meeting more diverse transport needs.

[0051] like Figure 6 and 7 As shown, in some embodiments of this application, the bottom surface of the axle 5 is provided with a hinge lug 8, and the top surface of the drive vehicle 2 is provided with a hinge plate 9. The hinge lug 8 and the hinge plate 9 are connected by a pin to form a vertical rotary joint. The hinge lug 8 is located on the bottom surface of the axle 5 and is usually a pair of symmetrically arranged ear-shaped structures used to cooperate with the hinge plate 9 on the top surface of the drive vehicle 2. The hinge plate 9 is fixed to the top of the drive vehicle frame 21, and its shape matches the hinge lug 8. After being connected by a pin, it forms a stable rotating joint. The pin is used to connect the hinge lug 8 and the hinge plate 9, ensuring free relative rotation between the two while providing sufficient strength and stability.

[0052] Through the vertical swivel joint, the drive vehicle 2 can rotate relative to the supporting pallet 4 in the vertical plane, allowing the inclined shaft rail transport vehicle to better adapt to the undulations and gradient changes within the tunnel. Especially on inclined shafts or slopes, this design ensures that the drive vehicle 2 maintains good contact with the rail, improving stability and safety. When the inclined shaft rail transport vehicle is going uphill or downhill or encounters uneven surfaces, the vertical swivel joint allows the drive vehicle 2 to automatically adjust its angle according to the terrain, reducing overturning moments caused by load or terrain changes. This helps prevent the inclined shaft rail transport vehicle from overturning or jumping during sudden stops or downhill sections, improving overall safety. The vertical swivel joint allows the braking components to automatically adjust according to the inclined shaft rail transport vehicle's posture, ensuring that braking force is evenly distributed across each friction wheel 231. This helps improve braking performance, shortens braking distance, and further enhances the safety of the inclined shaft rail transport vehicle.

[0053] Furthermore, the combination of vertical and horizontal slewing joints enables the inclined shaft rail transport vehicle to complete complex turning maneuvers within a limited space. This design significantly improves the turning capability and enhances the adaptability of inclined shaft rail transport vehicles, particularly in small-radius turning tunnels common in environments such as coal mines.

[0054] like Figure 6 As shown, in some embodiments of this application, the drive vehicle 2 includes a drive frame 21, and a hinged lug 9 is formed on the drive frame 21; the end of the drive frame 21 is provided with a traction seat 22 suitable for connecting a traction rod 3. The traction seat 22 can be connected to a fixing plate on the drive frame 21 by bolts, and the traction seat 22 cooperates with the traction rod 3, which can be connected to the power unit 1.

[0055] like Figure 6 As shown in some embodiments of this application, the drive frame 21 is further provided with a hinge plate 234 and a power assembly. The power assembly includes two parallel friction wheels 231, each connected to an actuator 232. Clamping arms 233 are connected to the actuators 232, with one end of each clamping arm 233 connected via the hinge plate 234. The hinge plate 234 is slidably or fixedly connected to a groove on the drive frame 21. The other end of each clamping arm 233 is connected via a clamping cylinder, which is installed in an elongated hole 25 on the drive frame 21. The actuator 232 includes a motor reducer. By providing a sliding connection between the hinge plate 234 and the drive frame 21, it is beneficial to compensate for the offset between the track centerline and the drive frame 21 centerline during small radius of curvature turns, eliminating or reducing overturning moments. The clamping cylinder is used to apply preload to clamp the track.

[0056] The hinge plate 234 on the drive frame 21 can be either a freely sliding double hinge plate or a slidingly connected single hinge plate.

[0057] like Figure 6 As shown in some embodiments of this application, a braking assembly is also provided on the drive frame 21. The braking assembly includes a brake 261, with brake arms 262 hinged to both ends of the brake 261. A brake shaft is hinged to the end of the brake arm 262 away from the brake 261, and a brake block is connected to the end of the brake shaft away from the brake arm 262. The brake arm 262 is connected to a brake connecting plate via a pin. Both the brake connecting plate and the brake shaft are connected to the drive frame 21. The braking assembly is symmetrically arranged on both sides of the power assembly at a 45° angle, which makes the braking force distribution uniform and also reduces the overall height of the machine.

[0058] In addition to the above structural arrangement, the number of braking components can be set to one, and the braking components are vertically mounted on the drive frame 21. The total height of the drive vehicle 2 can be kept unchanged by shortening the length of the brake arm 262 in the braking components.

[0059] like Figure 6As shown, in some embodiments of this application, the drive frame 21 is provided with load-bearing wheels 27 on both sides and guide wheels at the bottom. The load-bearing wheels 27 are connected to the drive frame 21 by nuts, and the guide wheels are located on both sides of the friction wheel 231. The guide wheels can prevent the drive vehicle 2 from jumping and overturning during emergency stops and provide a certain degree of protection for the friction wheel 231.

[0060] like Figure 5 As shown, some embodiments of the second aspect of this application provide a sloping track transport vehicle, including the sloping track transport drive mechanism in any of the embodiments of the first aspect described above.

[0061] like Figure 5 As shown, in some embodiments of this application, the inclined shaft rail transport vehicle further includes a power unit 1, a traction rod 3, and a bearing plate 4; the bearing plate 4 is connected to the inclined shaft rail transport drive mechanism and is suitable for realizing rotation in both horizontal and vertical directions; the power unit 1 is connected to the inclined shaft rail transport drive mechanism through the traction rod 3.

[0062] Two sets of drive vehicles 2 can be installed at the bottom of the support pallet 4. By installing two sets of drive vehicles 2 at the bottom of the support pallet 4, and the wheelbase of the drive vehicles 2 is much smaller than that of the support pallet 4, the friction wheel 231 is located between the two wheels of the drive vehicle 2 with a smaller wheelbase, and its turning radius is smaller, which is suitable for small-radius turning tunnels. Both sets of drive vehicles 2 are connected to the support pallet 4 through a slewing pair, which enables the inclined tunnel rail transport vehicle to complete turns in both horizontal and vertical directions with a smaller radius. The power unit 1 is connected to one of the drive vehicles 2 through the traction rod 3. The power unit 1 is a power compartment, and two sets of drive vehicles 2 are installed at the bottom of the power compartment.

[0063] In some embodiments of this application, the inclined shaft rail transport vehicle further includes a power unit 1 and a support plate 4; the support plate 4 is connected to the inclined shaft rail transport drive mechanism and is suitable for rotation in both horizontal and vertical directions, and the power unit 1 is disposed on the support plate 4.

[0064] Two sets of drive cars 2 can be installed at the bottom of the support pallet 4. By installing two sets of drive cars 2 at the bottom of the support pallet 4, and the wheelbase of the drive cars 2 is much smaller than the wheelbase of the support pallet 4, the friction wheel 231 is located between the two wheels of the drive car 2 with a small wheelbase, and its turning radius is smaller, which is suitable for small-radius turning tunnels. Both sets of drive cars 2 are connected to the support pallet 4 through a slewing pair, which enables the inclined tunnel rail transport vehicle to complete turns in both horizontal and vertical directions with a small radius. Since the weight of the power car or the load car is pressed down on the upper part, the overturning moment is eliminated or reduced.

[0065] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0066] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0067] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
