[0002] In the fields of mining and heavy material transportation, traditional mining heavy trucks play a crucial role. They are responsible for transporting large quantities of goods such as ores, waste rocks, equipment, and personnel. However, with the continuous expansion of mine scale and the increase in mining depth, traditional heavy trucks face numerous challenges under certain specific working conditions (such as long-distance ramp transportation, crossing complex terrains, and specific rail transportation areas), including but not limited to high energy consumption, severe tire wear, rising maintenance costs, and limited transportation efficiency.

[0003] Currently, the frame design of traditional mining heavy trucks is mainly optimized for road driving. Tires, as the only components in contact with the ground, bear the weight and driving force of the entire vehicle. However, in mines, especially in specific areas equipped with rails, relying solely on tires for driving will not only increase tire wear but also increase energy consumption and reduce transportation efficiency due to frequent starting, braking, and steering operations. Summary of the Utility Model

Detailed implementation manners

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0022] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the present utility model provides a frame device for a mine heavy truck and a track vehicle, as Figures 1-5As shown in the figure, the frame device of the mining heavy truck and the rail two-purpose vehicle includes: a frame 1, on which axles 2 are symmetrically and rotatably installed; heavy truck wheels 3 assembled on the corresponding axles 2, and the heavy truck wheels 3 are used for walking on hardened roads; rail wheels 4 fixedly sleeved on the axles 2, and the rail wheels 4 are used for walking on rails; assembly plates 5 symmetrically arranged at the front end of the frame 1 and with adjustable spacing; mounting brackets 6 respectively fixedly installed on the corresponding assembly plates 5, a rotating shaft 7 is rotatably installed on the mounting bracket 6, and a guide wheel 8 is fixedly installed on the rotating shaft 7, and the guide wheel 8 is used to guide the rail wheel 4 onto the rail; an adjusting mechanism is arranged on the frame 1, and the adjusting mechanism is used to adjust the spacing of the corresponding assembly plates 5.

[0024] It should be noted that in a mining environment, the road surface is often rough, covered with stones, mud and other possible obstacles, and these conditions cause particularly serious wear to the tires. Compared with flat roads, mining roads cause greater impact and friction on the sidewalls, treads and shoulders of tires, resulting in a significant reduction in tire life. In addition, sharp rocks or metal fragments that may exist in mines may also cause punctures or cuts in the tires, further increasing the frequency and cost of tire repair and replacement; in mining areas with rails, if heavy trucks still rely on tires for driving, frequent starting, braking and steering operations are required to adapt to the track direction and slope changes. These operations not only increase the load on the engine, but also waste a large amount of energy due to frequent kinetic energy conversion (such as kinetic energy being converted into heat). At the same time, due to the low friction coefficient between the tires and the ground (especially in wet or muddy mining environments), the traction of the vehicle will be affected, thereby affecting the climbing ability and overall transportation efficiency. For specific areas with rails in mines, the frame design and driving method of traditional mining heavy trucks need to be optimized and improved accordingly to meet the special requirements of the mining environment, improve transportation efficiency, reduce operating costs, and ensure the safety of operators;

[0025] In this embodiment, the vehicle frame 1 serves as the basic support structure of the entire device. The vehicle frame 1 is designed to be strong and durable, capable of withstanding the weight of a mining heavy truck and the impacts under various complex working conditions. The axles 2 are symmetrically and rotatably mounted on the vehicle frame 1. They not only support the heavy truck wheels 3 and the track wheels 4 but also allow them to rotate flexibly according to the driving conditions. The heavy truck wheels 3 are assembled on the corresponding axles 2 and are specifically used for traveling on hardened roads (such as the main roads in mines or well-maintained areas). The track wheels 4 are fixedly sleeved on the axles 2. When the vehicle needs to enter a specific area with tracks, the track wheels 4 will play a role to ensure the stable driving of the vehicle on the tracks. The mounting plates 5 are symmetrically arranged at the front end of the vehicle frame 1 and the distance between them is adjustable. This design enables the guide wheels 8 to be flexibly adjusted according to the width of different tracks, ensuring that the guide wheels can accurately guide the track wheels 4 into the tracks. The mounting brackets 6 are fixedly installed on the corresponding mounting plates 5 to provide a stable support for the rotating shafts 7. The rotating shafts 7 are rotatably mounted on the mounting brackets 6, allowing the guide wheels 8 to rotate as necessary to adapt to the track direction. The guide wheels 8 are fixedly installed on the rotating shafts 7 and are used to guide the track wheels 4 into the tracks. The presence of the guide wheels 8 greatly simplifies the transition process of the vehicle from the ordinary road surface to the tracks, improving the convenience and safety of operation. The adjusting mechanism is used to control the distance between the corresponding mounting plates 5 so as to adapt to tracks of different widths. This flexibility enables the vehicle to travel smoothly on various mining tracks. By the division of labor between the heavy truck wheels 3 and the track wheels 4, the wear and replacement frequency of the tires in the harsh mining environment are reduced, thereby reducing the maintenance and replacement costs. At the same time, track driving also reduces fuel consumption and engine load. The design of the guide wheels 8 enables the vehicle to smoothly transition from the ordinary road surface to the tracks, reducing potential safety hazards caused by improper operation or uneven road surfaces. In addition, track driving itself has high stability, which helps to reduce the risk of accidents such as rollovers.

[0026] In a further preferred embodiment of the present utility model, the adjusting mechanism includes: bearing seats 9 symmetrically and fixedly installed on the vehicle frame 1; a bidirectional screw rod 10 rotatably mounted on the bearing seats 9, and the bidirectional screw rod 10 threadedly penetrates through the corresponding mounting plate 5; a guide rod 11 fixed on the bearing seats 9, and the guide rod 11 penetrates through the corresponding mounting plate 5; a motor 12 assembled on the vehicle frame 1, and the output shaft of the motor 12 is fixedly connected to the bidirectional screw rod 10 through a coupling 13.

[0027] In this embodiment, the bearing blocks 9 are symmetrically and fixedly mounted on the vehicle frame 1, providing a stable support and a rotation center for the bidirectional screw 10. The design of the bearing blocks 9 ensures the stability and accuracy of the bidirectional screw 10 during rotation; the bidirectional screw 10 is rotatably mounted on the bearing blocks 9 and threadedly penetrates the corresponding assembly plates 5. The special feature of the bidirectional screw 10 is that the thread directions on both sides are opposite. When the bidirectional screw 10 rotates, it will simultaneously drive the two assembly plates 5 to move in opposite directions, thereby adjusting the distance between them; the guide rods 11 are fixed on the bearing blocks 9 and penetrate the corresponding assembly plates 5. The function of the guide rods 11 is to guide the movement of the assembly plates 5, ensuring that the assembly plates 5 can maintain linear motion when adjusting the distance, and avoiding deviation or shaking; the motor 12 is assembled on the vehicle frame 1 and serves as a power source to drive the bidirectional screw 10 to rotate. As the distance between the assembly plates 5 changes, the distance between the guide wheels 8 also changes accordingly, enabling the guide wheels 8 to fit the track and playing a stable guiding role.

[0028] In a further preferred embodiment of the present utility model, a bracket 14 is fixed on one side of the mounting frame 6, a water pipe 15 is assembled on the bracket 14, and a spray head 16 is fixedly connected and communicated at the water outlet end of the water pipe 15. The spray head 16 is used to sprinkle water on the guide wheel 8.

[0029] In this embodiment, by adding a combination of the bracket 14, the water pipe 15 and the spray head 16 on the mounting frame 6, a function of sprinkling water for cooling and cleaning the guide wheel 8 is provided; the bracket 14 is fixedly mounted on one side of the mounting frame 6, providing a stable support for the water pipe 15; the water pipe 15 is assembled on the bracket 14 and is used to convey water source to the spray head 16; the spray head 16 is fixedly connected and communicated at the water outlet end of the water pipe 15 and is used to evenly spray the water flow onto the guide wheel 8. In a mine environment, a large amount of heat will be generated after the guide wheel 8 rubs against the track for a long time. If the temperature is not reduced in time, it may cause accelerated tire aging, performance degradation or even damage. By sprinkling water on the guide wheel 8 through the spray head 16, the surface temperature can be effectively reduced, the service life can be prolonged, and the driving safety can be improved.

[0030] In a further preferred embodiment of the present utility model, limit blocks are symmetrically and fixedly sleeved on the bidirectional screw 10, and the limit blocks are used to separate the corresponding assembly plates 5.

[0031] In this embodiment, the limit blocks are symmetrically fixed on the bidirectional screw 10, and their positions are set according to the maximum and minimum distance requirements of the assembly plates 5. The main function of the limit blocks is to separate the corresponding assembly plates 5 to prevent them from colliding with each other or exceeding the predetermined moving range during the adjustment process.

[0032] In a further preferred embodiment of the present utility model, threaded holes and sliding holes are formed in the assembly plates 5. The threaded holes are adapted to the bidirectional screw 10, and the sliding holes are adapted to the guide rods 11.

[0033] In this embodiment, the threaded holes are formed in the mounting plate 5, and their sizes and pitches are matched with the threads of the bidirectional screw 10. When the bidirectional screw 10 rotates, the mounting plate 5 can move along the direction of the threaded holes, thereby realizing the adjustment of the spacing; the sliding holes are formed side by side with the threaded holes in the mounting plate 5, and their sizes are slightly larger than the diameter of the guide rod 11 to ensure that the guide rod can smoothly pass through the sliding holes without excessive friction.

[0034] In a further preferred embodiment of the present utility model, a joint is provided at the water inlet end of the water pipe 15, and the joint is used to connect the water supply pipe. A reinforcing rod is fixedly installed on the bracket 14, and one end of the reinforcing rod is fixedly connected to the mounting bracket 6.

[0035] In this embodiment, the joint at the water inlet end of the water pipe 15 is designed such that the sprinkler system can be conveniently connected to an external water supply pipe to provide stable water flow for the nozzles. The reinforcing rod fixedly installed on the bracket 14 effectively enhances the connection strength between the bracket and the mounting bracket 6.

[0036] In a further preferred embodiment of the present utility model, a support is provided on the vehicle frame 1, and the support is fixedly connected to the motor 12. A bolt for limiting is provided on the support, and the bolt is threadedly connected to the vehicle frame 1.

[0037] In this embodiment, the support is installed on the vehicle frame 1, and its main function is to serve as a fixed support point for the motor 12. A bolt for limiting is provided on the support and is threadedly connected to the vehicle frame 1. The main function of the bolt is to limit the position of the support.

[0038] In a further preferred embodiment of the present utility model, the water pipe 15 is made of stainless steel, the water outlet end of the nozzle 16 faces the corresponding guide wheel 8, and a pipe clamp adapted to the water pipe 15 is provided on the bracket 14.

[0039] In this embodiment, the water pipe 15 is made of stainless steel. Stainless steel has excellent corrosion resistance and durability, and can resist common corrosive substances and harsh weather conditions in the mine environment, ensuring the long-term stable operation of the water pipe, reducing leakage and replacement frequency caused by corrosion; the water outlet end of the nozzle 16 faces the corresponding guide wheel 8. This design ensures that the effects of sprinkler cooling and cleaning can directly act on the guide wheel 8, effectively reducing its surface temperature and removing dust and impurities attached to the surface, extending its service life; the function of the pipe clamp is to firmly fix the water pipe 15 on the bracket 14 to prevent it from loosening or falling off due to vibration during vehicle driving, ensuring the stability and reliability of the sprinkler system.

[0040] In summary, by adjusting the bidirectional screw 10 and the guide rod 11 in the adjustment mechanism, the spacing of the assembly plate 5 can be flexibly adjusted, so as to drive the guide wheel 8 to adapt to the track width, ensuring that the vehicle can drive smoothly on various mine tracks; the division of labor between the heavy truck wheels 3 and the track wheels 4, as well as the design of the guide wheel 8, enable the vehicle to smoothly transition from the ordinary road surface to the track, reducing potential safety hazards caused by improper operation or uneven road surfaces. The track driving itself also has high stability, which helps to reduce the risk of accidents such as rollovers; the division of labor between the heavy truck wheels 3 and the track wheels 4 reduces the wear and replacement frequency of the tires in the harsh mine environment, reducing the maintenance and replacement costs; through the combination of the bracket 14, the water pipe 15 and the nozzle 16 on the mounting frame 6, the guide wheel 8 is provided with the functions of sprinkler cooling and cleaning, effectively reducing the surface temperature of the guide wheel after long-term operation, extending the service life and improving the driving safety.
