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 utility model relates to the field of tunnel engineering equipment, specifically to a 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] 1. When there are many driving vehicles, the overall length of the inclined shaft rail transport vehicle will increase, affecting the flexibility of its use; 2. The driving vehicle is connected to the carrying pallet through the traction rod. Due to its light weight, when the inclined shaft rail transport vehicle brakes suddenly downhill, the overturning moment generated by the inertia of the carrying pallet will cause wear on the friction wheel and the intermediate track.

[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. Utility Model Content

[0007] The purpose of this invention is to provide a drive mechanism and a rail transport vehicle for inclined shafts, which reduces wear on friction wheels and intermediate rails, facilitates turning, and is suitable for complex, small-radius turning tunnels.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a inclined shaft track transport drive mechanism, equipped with a load-bearing pallet, comprising:

[0009] Drive vehicle;

[0010] The axle is rotatably connected to the top of the drive vehicle to form a vertical slewing joint;

[0011] The drive vehicle is connected to the load-bearing pallet via the axle, and the axle is rotatably connected to the load-bearing pallet to form a horizontal slewing joint.

[0012] A power unit, which is mounted on a drive frame, includes a hydraulic motor.

[0013] A further technical solution also includes a rotary shaft, which is disposed at the bottom of the bearing plate and inserted into the center hole of the axle and locked in place. The top surface of the axle is in contact with the bottom surface of the bearing plate and can make horizontal circular motion around the rotary shaft to form a horizontal rotary pair.

[0014] A further technical solution is that the bottom surface of the axle is provided with multiple arc-shaped load-bearing beams, which cooperate with the arc-shaped support plate on the top of the drive vehicle and are fastened by guide limit blocks and bolts to form a vertical slewing pair.

[0015] In a further technical solution, the driving vehicle also includes a driving frame, and a traction seat is provided on one side of the driving frame. The traction seat is used to cooperate with the traction rod for installation.

[0016] In a further technical solution, the power assembly also includes two friction wheels arranged in parallel. Each of the two friction wheels is connected to an actuator by bolts. The actuator is the hydraulic motor. A clamping arm is connected to the actuator by bolts. One end of the two clamping arms is connected by a hinge plate, and the other end of the two clamping arms is connected by a clamping cylinder. The clamping cylinder is installed in an elongated hole on the drive frame.

[0017] In a further technical solution, a groove is provided on the drive frame, and the hinge plate is slidably connected in the groove.

[0018] In a further technical solution, the drive frame is also provided with a braking assembly, the braking assembly includes a brake, both ends of the brake are hinged to brake arms, the end of the brake arm away from the brake is hinged to a brake shaft, the end of the brake shaft away from the brake arm is connected to a brake block, and a brake connecting plate is connected to the brake arm by a pin, the brake connecting plate and the brake shaft are both connected to the drive frame.

[0019] In a further technical solution, load-bearing wheels are provided on both sides of the drive frame, and guide wheels are provided at the bottom of the drive frame.

[0020] This application also provides an inclined track transport vehicle, including the inclined track transport drive mechanism described above.

[0021] A further technical solution includes a power unit, a traction rod, and the carrying pallet. The inclined track transport drive mechanism is installed at the bottom of the carrying pallet, and the power unit is connected to the inclined track transport drive mechanism through the traction rod. The power unit is mounted on the carrying pallet.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. The drive vehicle is located at the bottom of the load-bearing pallet, which does not occupy the effective workpiece and facilitates the loading, unloading and transfer of goods in a low space.

[0024] 2. The drive vehicle and the load-bearing pallet are connected by two slewing pairs, enabling flexible rotation in both horizontal and vertical directions. The sliding connection between the articulated plate and the drive vehicle frame can compensate for the offset between the track centerline and the drive vehicle frame centerline when turning with a small radius of curvature, reducing the overturning moment and enabling the vehicle to take small-radius turns with stable operation.

[0025] 3. The guide wheel can prevent the vehicle from jumping and overturning during emergency stops and also protects the friction wheel. Attached Figure Description

[0043] like Figure 5 , Figure 6 and Figure 7 As shown, a inclined track transport drive mechanism, loaded with a support pallet 4, includes: a drive vehicle 2; an axle 5 rotatably connected to the top of the drive vehicle 2 to form a vertical slewing joint; the drive vehicle 2 and the support pallet 4 are connected via the axle 5, and the axle 5 and the support pallet 4 are rotatably connected to form a horizontal slewing joint; and a power assembly 23, which is mounted on the drive vehicle frame 21 and includes a hydraulic motor.

[0044] Specifically, by placing the drive vehicle 2 at the bottom of the support pallet 4, it does not occupy effective space, shortens the length of the inclined shaft rail transport drive mechanism and the inclined shaft rail transport vehicle, and does not hinder the loading of goods in low space. The axle 5 is rotatably connected to the support pallet 4, forming a horizontal slewing pair, which enables the inclined shaft rail transport vehicle to complete a small radius of horizontal turning. The axle 5 is rotatably connected to the top of the drive vehicle 2, forming a vertical slewing pair, which enables vertical turning and improves the applicability.

[0045] Hydraulic motors are generally not sensitive to oil contamination and have the advantages of impact resistance and low inertia, making them suitable for the working environment of coal mine roadways.

[0046] In one or more embodiments, the rotary shaft 6 is disposed at the bottom of the bearing plate 4. The rotary shaft 6 is generally integral with the bearing plate 4. The rotary shaft 6 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 bearing plate 4 and can make horizontal circular motion around the rotary shaft 6 to form a horizontal rotary pair.

[0047] In one or more embodiments, the bottom surface of the axle 5 is provided with multiple arc-shaped bearing beams, which cooperate with the arc-shaped support plate on the top of the drive vehicle 2 and are fastened by guide limit blocks 7 and bolts to form a vertical slewing pair.

[0048] Specifically, the design of the two slewing joints allows the drive vehicle 2 to rotate horizontally and vertically relative to the load-bearing pallet 4. When turning, the drive vehicle 2 can rotate flexibly relative to the load-bearing pallet 4, thereby reducing the overturning moment caused by the change in track curvature when the transport vehicle makes a small-radius turn, thus ensuring the stability of transportation.

[0049] Reference Figures 6 to 10 In one or more embodiments, the drive vehicle 2 further includes a drive frame 21, and a traction seat 22 is provided on one side of the drive frame 21. The traction seat 22 is used to cooperate with the traction rod 3 for installation.

[0050] In one or more embodiments, the power assembly 23 further includes two parallel friction wheels 231, each of which is bolted to an actuator 232, which is the hydraulic motor. Each actuator 232 is bolted to a clamping arm 233, one end of which is connected to a hinge plate 234, and the other end of which is connected to a clamping cylinder 235. The clamping cylinder 235 is installed in an elongated hole on the drive frame 21 and is used to apply a preload to clamp the track.

[0051] In one or more embodiments, the drive frame 21 is provided with a sliding groove, the hinge plate 234 is slidably connected in the sliding groove, and the drive frame 21 is provided with a square hole 29. The square hole 29 is used to prevent the friction wheel 231 from causing interference between the hydraulic motor and the drive frame 21 due to the sliding of the hinge plate 234. By setting the sliding connection between the hinge plate 234 and the drive frame 21, it is beneficial to compensate for the offset between the center line of the track and the center line of the drive frame 21 when turning with a small radius of curvature, reduce the overturning moment, and make the transport vehicle more stable when turning.

[0052] In one or more embodiments, the drive frame 21 is further provided with a braking assembly 26. The braking assembly 26 is symmetrically arranged on both sides of the power assembly 23 at a 45° angle, which makes the braking force distribution uniform and also reduces the height of the whole machine. The braking assembly 26 includes a brake 261. The two ends of the brake 261 are hinged to brake arms 262. The end of the brake arm 262 away from the brake 261 is hinged to a brake shaft 263. The end of the brake shaft 263 away from the brake arm 262 is connected to a brake block 264. A brake connecting plate 265 is connected to the brake arm 262 through a pin 10. Both the brake connecting plate 265 and the brake shaft 263 are connected to the drive frame 21.

[0053] In one or more embodiments, the drive frame 21 is provided with load-bearing wheels 27 on both sides. The shaft section of the load-bearing wheel 27 is inserted into the drive frame 21. The shaft section is threaded and tightened onto the drive frame 21 with a nut. The bottom of the drive frame 21 is provided with guide wheels 28. The guide wheels 28 are located on both sides of the friction wheel 231. The guide wheels 28 can prevent the drive vehicle 2 from jumping and overturning under emergency stop conditions and provide a certain degree of protection for the friction wheel 231.

[0054] In one or more embodiments, the present invention also provides an inclined track transport vehicle, including the inclined track transport drive mechanism in any of the above embodiments.

[0055] In one or more embodiments, the inclined shaft rail transport vehicle further includes a power unit 1, a traction rod 3, and the bearing pallet 4. The inclined shaft rail transport drive mechanism is installed at the bottom of the bearing pallet 4. The power unit 1 is connected to the inclined shaft rail transport drive mechanism through the traction rod 3. The power unit 1 is set on the bearing pallet 4. Two sets of drive vehicles 2 are provided. The wheelbase of the drive vehicles 2 is much smaller than the wheelbase of the bearing 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. The power unit 1 is connected to the traction seat 22 of one set of drive vehicles 2 through the traction rod 3. The power unit 1 is a power compartment.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
