Description

Technical Field

[0001] The present invention belongs to the technical field of mine transportation, and in particular relates to a mine transport vehicle and a mine rail transport system. Background Art

[0002] In the mining industry, efficient and safe transportation of materials has always been one of the key factors in improving production efficiency. With the continuous increase in the depth of mining, traditional ground transportation methods have gradually exposed problems such as long transportation distance, high cost, and low efficiency. Therefore, underground transportation has become an effective way to solve these problems. In underground transportation systems, rail transportation is widely used due to its high transportation capacity and low cost. However, when carrying out rail transportation in closed or semi-closed circular pipes, due to space limitations and special working environments, traditional rail transportation systems face problems such as slow speed and poor stability, especially when climbing and turning. These problems not only affect transportation efficiency, but also pose a threat to the safety of mining operations.

[0003] In the existing rail transportation system, the design of the track has a crucial impact on the speed and stability of the vehicle. The traditional mine rail transportation system usually only lays a single track or double tracks on the ground, and mainly relies on gravity and simple mechanical structures to maintain the stability of the vehicle. However, in the face of complex terrain changes, especially long climbing sections, such a design often cannot provide sufficient power and support, resulting in a reduction in vehicle speed and even safety hazards.

[0004] The currently widely accepted improvement idea is to use enhanced power and optimized track design to improve the vehicle's operating performance in complex terrain. For example, some mine transportation systems use more powerful electric motors or diesel engines to provide greater traction and ensure that the vehicle can maintain a certain speed when climbing. In addition, in order to improve the stability of the vehicle when turning, some systems add additional lateral support devices on the original basis.

[0005] However, these solutions still have obvious limitations. First, although simply increasing the power can increase the speed of the vehicle to a certain extent, in a closed or semi-closed circular pipe, due to space limitations, excessive power output may cause the vehicle to lose control and increase the risk of accidents. Secondly, although the lateral support device can provide a certain degree of stability, the lateral support force it provides is limited when turning at high speeds, and it cannot completely eliminate the possibility of rollover. The specific reason is that there is not enough space in the mine, so the turning radius at the turn is usually small, so a larger lateral centripetal force is required when driving at high speeds, which can easily cause damage to the wall or the guide wheel structure of the vehicle body.

[0006] In summary, there is still a lack of a solution that can ensure both high-speed operation and stability.

[0007] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

Unless otherwise specified, the numbering of each method step is only for the purpose of identifying each method step, and does not limit the order of arrangement of each method or limit the scope of implementation of the present invention. The change or adjustment of the relative relationship thereof can also be regarded as the scope of implementation of the present invention without substantial changes in the technical content.

[0030] The sources of the raw materials and instruments used in the examples are not particularly limited and can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0031] like Figures 1 to 4 As shown, a mine rail transport system according to a preferred embodiment of the present invention includes a transport vehicle 1 and a driving channel.

[0032] The driving channel is a closed or semi-closed pipeline, and its structure includes at least a ground 81 and two side walls 82. The first track 31 and the second track 32 are respectively arranged on the ground 81 and the two side grounds 81. Two first tracks 31 are arranged on the ground 81, and one second track 32 is arranged on the two side walls 82. Based on the requirements of laying tracks, it is also necessary to lay sleepers to ensure that sufficient support can be provided. Figure 1 The first track 31 and the second track 32 are only schematically represented.

[0033] Three arms 4 are respectively arranged on both sides of the transport vehicle 1. The proximal end of the arm 4 is fixedly connected to the body of the transport vehicle 1. The distal end of the arm 4 is connected to the mounting seat 6, and the mounting seat 6 is rotatably connected to the lateral power wheel 22. The specific structure is: the mounting seat 6 includes a base plate 61, a positioning rod 62 and a spring 63. The base plate 61 includes a plate body 611 and a protrusion 612. At least two positioning rods 62 need to be arranged, and in this embodiment, four are arranged and arranged parallel to each other. The axial direction of the positioning rod 62 is consistent with the width direction of the transport vehicle 1. One end of the positioning rod 62 is fixedly connected to the support, and the positioning rod 62 penetrates the plate body 611 to achieve a sliding connection with the base plate 61. There are also four springs 63 and they are sleeved on each positioning rod 62, and the spring 63 is located between the base plate 61 and the arm 4. When the spring 63 is compressed, it can generate a force on the base plate 61 to make it away from the arm 4, and the positioning rod 62 plays a role in constraining the moving direction of the base plate 61. The protrusion 612 is rotatably connected to a rotating shaft, and the rotating shaft is coaxially fixedly connected to the lateral power wheel 22.

[0034] The bottom of the transport vehicle 1 is provided with a main power wheel 21. For the purpose of driving, at least two sets of the main power wheel 21 are required. The main power wheel 21 and the lateral power wheel 22 are respectively arranged on the first track 31 and the second track 32.

[0035] The transport vehicle 1 is provided with a power assembly 7. The power assembly 7 includes a power module 71, a first motor 72, and a second motor 73. The power module 71 is used to supply power to the first motor 72 and the second motor 73. The first motor 72 is used to drive the main power wheel 21 to rotate, and the second motor 73 is used to drive the lateral power wheel 22 to rotate. Specifically, the first motor 72 is fixed inside the transport vehicle 1 and is arranged in accordance with the structural form of the prior art, and can directly drive the main power wheel 21. Figure 1-2 The first motor 72 is not shown. The important second motor 73 is fixedly connected to the plate body 611, and the output shaft of the second motor 73 is coaxially fixedly connected to the rotating shaft to achieve the driving of the lateral power wheel 22.

[0036] The outer contour of the transport vehicle 1 is streamlined to reduce wind resistance during operation. The transport vehicle 1 is provided with a plurality of protective covers 5 for covering the support arm 4, the mounting seat 6 and the second motor 73, but the lateral power wheel 22 is exposed from the protective cover 5.

[0037] When the transport vehicle 1 is traveling, the second track 32 contacts the lateral power wheel 22 and forces the spring 63 to deform. The spring 63 will generate sufficient force to make the lateral power wheel 22 close to the second track 32, ensuring that the lateral power wheel 22 can generate driving force for the transport vehicle 1 when it actively rotates.

[0038] When “fixed connection” is mentioned in this solution, unless otherwise specified, a connection solution in the prior art, such as welding, threaded connection or fastener connection, should be adaptively selected.

[0039] This solution includes at least the following features: First, the addition of the second motor 73 increases the total output power, thereby increasing the travel speed of the transport vehicle 1; second, by arranging the second track 32 in the travel channel, it is possible to provide the transport vehicle 1 with more stable lateral support, thereby improving the form stability.

[0040] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the claims and their equivalents.
