Description

Technical Field

[0001] This invention relates to the field of rail transport vehicle technology, and in particular to a mining mobile vehicle and a mining mobile train set. Background Technology

[0002] Mining mobile carts are crucial transportation equipment in fully mechanized coal mining faces, characterized by heavy loads and low speeds. As coal mining progresses towards deeper and larger-scale operations, the amount of equipment on the working face increases, requiring frequent movement to keep pace with the face's advancement. The traditional "track laying + winch pulling" transportation method is insufficient to meet the demands for efficient transport and movement of large quantities of equipment, prompting the innovation and upgrading of mining mobile carts to meet the requirements of efficient coal mining.

[0003] Authorization announcement number CN206358142U discloses a small turning radius rail vehicle. The steering mechanism of the small turning radius rail vehicle includes a first support member, a second support member, and a rotating assembly. The first and second support members rotate freely via the rotating assembly. The first and second support members are respectively fixedly connected to the load-bearing platform and wheel set of the small turning radius rail vehicle.

[0004] When a rail vehicle with a small turning radius turns on the track, the angular velocities of the wheel sets on both sides are different, causing it to detach from the track. In practice, a differential mechanism is often required to solve this problem, which increases the structural complexity of the wheel set. Summary of the Invention

[0005] In view of this, and to address the above-mentioned shortcomings, it is necessary to propose a mobile mining vehicle.

[0006] It is also necessary to propose a mining mobile train set.

The rotation axis between the wheel assembly and the carrying platform is a second rotation axis. The top surface of the carrying platform is a carrying plane. The second rotation axis is perpendicular to the carrying plane. The wheel assembly includes an axle and a wheel body. The axle is mounted on the steering assembly. A wheel body is provided on each side of the axle. Each wheel body on either side is in rolling contact with a guide rail. The axle is rotatably connected to the steering assembly. The axle and the wheel body rotate synchronously. The guide rail has at least one arc segment. The wheel body includes a roller.

Detailed Implementation

[0024] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] See Figures 1 to 3 This invention provides a mining mobile vehicle 10, including a carrying platform 11, a steering assembly 13, and a wheel assembly 14. The wheel assembly 14 is rotatably connected to the carrying platform 11 through the steering assembly 13. The rotation axis between the wheel assembly 14 and the carrying platform 11 is a second rotation axis. The top surface of the carrying platform 11 is a carrying plane. The second rotation axis is perpendicular to the carrying plane. The wheel assembly 14 includes an axle 141 and a wheel body 142. The axle 141 is mounted on the steering assembly 13. A wheel body 142 is provided on each side of the axle 141. The wheel body 142 on either side is in rolling engagement with a guide rail 30. The axle 141 is rotatably connected to the steering assembly 13. The axle 141 and the wheel body 142 rotate synchronously. The guide rail 30 has at least one arc segment. The wheel body 142 includes a roller 1421. The annular wall of the roller 1421 is a first rolling surface, which is a conical surface.

[0026] Specifically, the steering assembly 13 is a slewing bearing with an outer diameter of φ732mm. Two wheel assemblies 14 are provided on the support platform 11, and the two wheel assemblies 14 are arranged one in front of the other along the length of the support platform 11.

[0027] Specifically, the axle 141 is fixed to the steering assembly 13 by a bearing in the prior art.

[0028] Specifically, the guide rail 30 and the wheel body 142 can be standard parts.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] The first rolling surface of the two rollers 1421 is designed as a conical surface. The diameter of the first rolling surface of the two rollers 1421 at the contact point with the corresponding guide rail 30 is continuously adjusted to make the angular velocity of the two rollers 1421 equal. The bearing platform 11 can be automatically adjusted to the center of the two guide rails 30 relative to the guide rail 30, thereby simplifying the structural complexity of the wheel assembly 14.

[0031] See Figures 1 to 3 Furthermore, the top surface of the guide rail 30 is a second rolling surface, and the width of the first rolling surface is greater than that of the second rolling surface.

[0032] Taking a bearing platform 11 with a length of 3890 mm, a width of 1300 mm, and a height of 376 mm as an example, the radius of the arc segment is 11 m, and the width of the first rolling surface is at least 3 mm wider than the width of the second rolling surface. The specific dimensions can be calculated conventionally and will not be described in detail.

[0033] See Figures 1 to 3 Furthermore, strip-shaped protrusions are provided on the first rolling surface.

[0034] See Figures 1 to 3 Furthermore, the wheel body 142 includes an inner wheel 1422, the inner sidewall of which is a conical surface.

[0035] Specifically, the distance between the inner walls of the two inner wheel 1422 of the same wheel assembly 14 is less than the distance between the inner sides of the two guide rails 30.

[0036] See Figures 1 to 3 Furthermore, the wheel body 142 includes an outer retaining wheel 1423, the inner sidewall of which is a conical surface.

[0037] Specifically, the distance between the inner walls of the two outer wheel 1423 of the same wheel assembly 14 is greater than the distance between the outer sides of the two guide rails 30.

[0038] Specifically, the inner wall of the inner retaining wheel 1422, the inner wall of the outer retaining wheel 1423, and the ring wall of the roller 1421 together form a concave groove.

[0039] See Figures 1 to 3 Furthermore, the mining mobile vehicle 10 includes a power mechanism 40, which is mounted on the steering assembly 13 and is used to drive the axle 141 to rotate.

[0040] In one specific embodiment, the power mechanism 40 includes a hydraulic motor 41, a planetary reducer 42, a pinion 43, and a gear 44. The output end of the hydraulic motor 41 is connected to the input end of the planetary reducer 42. The output end of the planetary reducer 42 is equipped with the pinion 43, which meshes with the gear 44. The gear 44 is mounted on the axle 141.

[0041] The hydraulic motor 41 and planetary reducer 42 are designed as a single unit and purchased externally. The combined design of the hydraulic motor 41 and planetary reducer 42 is suitable for heavy-duty power configurations.

[0042] In one specific embodiment, the large gear 44 is positioned off-center from the axle 141. Considering the underground coal mine, the ground at the center of the two guide rails 30 is higher than the sides, and the large gear 44, being positioned at the center of the axle 141, would experience more severe impact with the ground.

[0043] See Figure 1 , Figure 4This invention provides a mining mobile train set, including a connecting rod 20 and mining mobile vehicles 10. There are at least two vehicles 10, and a connecting rod 20 is provided between two adjacent vehicles 10. The connecting rod 20 is rotatably connected to the carrying platform 11.

[0044] In one embodiment, the axis of rotation between the connecting rod 20 and the bearing platform 11 is a first axis of rotation, which is perpendicular to the bearing plane. Taking a train consisting of two bicycles 10 as an example, when the first bicycle 10 begins to turn while the second bicycle 10 has not yet turned, the first bicycle 10 may overturn under the action of centrifugal force. Because the first and second bicycles 10 rotate around the first axis of rotation, the second bicycle 10 hinders the overturning of the first bicycle 10. In a train consisting of at least two bicycles 10, the bicycles 10 restrain each other during operation, which makes the train more stable and prevents the turning bicycle 10 from overturning.

[0045] See Figure 1 , Figure 2 Furthermore, the mining mobile vehicle 10 includes an adapter 12, which includes an adapter plate 121 and a pin 122. The adapter plate 121 is fixed on the bearing platform 11. The connecting rod 20 is provided with a first pin hole, and the adapter plate 121 is provided with a second pin hole. The pin 122 passes through the first pin hole and the second pin hole in sequence.

[0046] See Figure 1 , Figure 2 Furthermore, there are two adapter plates 121, and the two adapter plates 121 are parallel to each other.

[0047] Specifically, there are two adapter plates 121, which are arranged in parallel, one above the other, and the connecting rod 20 is clamped between the two adapter plates 121.

[0048] See Figure 1 , Figure 2 Furthermore, the adapter 12 includes baffles, with one baffle on each side of the adapter plate 121.

[0049] The modules or units in the device of this invention can be merged, divided, or deleted according to actual needs.

[0050] The steps in the method of this invention can be adjusted, combined, or deleted according to actual needs.

[0051] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
