Description

Technical Field

[0001] This invention relates to the field of underground mining technology, specifically to an explosion-proof lithium battery trackless mining vehicle for non-coal underground mines. Background Technology

[0002] Non-coal underground mines are an important part of my country's mineral resource supply system. With the increasing mining depth and continuous expansion of mining scale, the underground transportation system, as the main artery of mine production, is directly related to mine capacity and economic benefits in terms of its operating efficiency and safety. Trackless mining vehicles, with their characteristics of mobility, flexibility and strong adaptability, have become the main transportation equipment for non-coal underground mines. For example, the patent with announcement number CN120716561A discloses a trackless rubber-tired ore unloading device for mining. Two fixed frames are symmetrically fixedly installed on both sides of the ore transport vehicle. Multiple parallel unloading structures are connected in the middle of the two fixed frames. The unloading structures are slidably installed in the middle of the ore transport vehicle. Connecting components are provided at both ends of the unloading structures. Two adjacent unloading structures are connected by the connecting components. A support mechanism and a discharge mechanism are fixedly installed at the tail end of the fixed frames. This allows the multiple unloading structures to separate the ore inside the ore transport vehicle, disperse the pressure of the ore on the car body, and allow the multiple unloading structures to discharge the ore in batches during unloading, ensuring the stability of the ore and the ore transport vehicle during unloading. For example, the patent with announcement number CN202358166U describes an underground mining vehicle. The drive shaft transmits power to the front and rear drive axles, driving the underground mining vehicle and the working mechanism. It adopts four-wheel drive with four forward gears and four reverse gears. Its average transport distance is 1.6 to 3.2 km. The vehicle can travel back and forth without turning around. The driver's seat is arranged laterally, so the driver has the same field of vision whether moving forward or backward. The underground mining vehicle adopts a low body, a central articulated frame, and a rear-mounted carriage, which is suitable for trackless transportation operations in underground metal mines and tunnel projects. For example, the patent with publication number CN213799262U describes an underground trackless mining truck. The underground mining truck has a centrally articulated body. The front frame is mounted on the front drive axle. The engine system is mounted at the front of the front frame. A hydraulic torque converter is installed at the flywheel output end of the engine system. A double gear pump is installed at the power take-off port of the hydraulic torque converter. The gearbox is mounted at the rear of the front frame. The hydraulic torque converter and the gearbox, and the gearbox and the front drive axle are connected by a universal joint drive shaft. The cab is mounted on the left front end of the front frame, and the rear frame is mounted on the rear drive axle. Most of the existing technologies mentioned above improve the overall structure. However, existing lithium battery trackless mining vehicles face problems such as dust, large temperature changes, and strong impact loads in the complex environment of non-coal underground mines. As a high-energy object, lithium-ion batteries can cause unimaginable consequences if they experience thermal runaway in the confined space underground, thus posing certain safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide an explosion-proof lithium battery trackless mining vehicle for non-coal underground mines, in order to solve the problems mentioned in the background art, such as the complex environment of non-coal underground mines, the presence of dust, large temperature changes, and strong impact loads, and the fact that lithium-ion batteries, as high-energy materials, could suffer unimaginable consequences if thermal runaway occurs in the confined space underground, thus posing certain safety hazards.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof lithium battery trackless mining vehicle for non-coal underground mines, comprising a mining vehicle base, a lithium battery component installed on the inner side of the mining vehicle base, and a transmission wheel component provided on the outer side of the mining vehicle base, wherein the lithium battery component supplies power to drive the transmission wheel component; a liquid storage pre-reservoir component is provided on the outer side of the mining vehicle base, and a docking eccentric wheel is provided at the shaft end of the transmission wheel component, wherein the outer side of the docking eccentric wheel corresponds to the outer side of the liquid storage pre-reservoir component; an explosion-proof pressure relief structure is provided between the mining vehicle base and the liquid storage pre-reservoir component, and the safety status of the lithium battery component is controlled by guiding the explosion-proof pressure relief structure.

[0005] Furthermore, the explosion-proof pressure relief structure is provided with a fitting piston component, which is nested and connected to the inner side of the liquid storage pre-reserved component. The outer side of the fitting piston component is fixedly connected with a contacting nesting component, and the outer side of the contacting nesting component corresponds to the outer side of the docking eccentric wheel. The outer side of the fitting piston component is fixedly connected with a return spring, and the return spring is connected to the inner side of the liquid storage pre-reserved component.

[0006] Furthermore, a supply spray pipe component is provided through the outer side of the liquid storage pre-reservation component, and the outer side of the supply spray pipe component extends to the lower end of the ore transport vehicle base. A flexible material bonding pre-reservation layer is symmetrically provided on the inner wall of the supply spray pipe component. A sponge isolation layer is provided between the lower end of the lithium battery component and the ore transport vehicle base. The abutting nesting component drives the bonding piston component to apply lateral pressure along the inner side of the liquid storage pre-reservation component. The liquid storage pre-reservation component with internal negative pressure will supply atomized liquid to the outer side of the sponge isolation layer at the lower end of the lithium battery component through the supply spray pipe component.

[0007] Furthermore, the transmission wheel component drives the docking eccentric wheel to rotate in a circular motion, and when the outer side of the docking eccentric wheel moves to contact the outer end of the abutting nest, the pressed abutting nest drives the fitting piston component to fit along the inner side of the liquid storage pre-reserved component.

[0008] Furthermore, the liquid storage pre-reservation component forms an elastic support structure between the reset spring and the fitting piston component, and the liquid storage pre-reservation component with internal negative pressure is supplied to the outside of the sponge isolation layer through the supply spray pipe component to form an atomization supply.

[0009] Furthermore, the front end of the ore-carrying vehicle base is provided with a guiding and protective structure, which controls the forward movement of the ore-carrying vehicle base. The guiding and protective structure is provided with a transverse corrugated liquid bladder component, which is located on the outside of the contact nesting component. The other side of the transverse corrugated liquid bladder component is connected to the outside of the liquid storage pre-reservation component. A supply hose is provided on the outside of the transverse corrugated liquid bladder component, and the supply hose runs through and connects to the inside of the ore-carrying vehicle base.

[0010] Furthermore, a nested docking component is nested at the front end of the ore transport vehicle base, and an isolation movable component is fixedly connected to the outside of the nested docking component. A spherical liquid-bearing bladder component is docked to the inside of the isolation movable component, and the outside of the spherical liquid-bearing bladder component is docked with the front end of the ore transport vehicle base. The spherical liquid-bearing bladder component is also docked with the end of the supply hose.

[0011] Furthermore, as the abutting nesting member moves along the inner side of the liquid storage pre-reserved member, the transverse corrugated liquid bladder component that docks with it will be under negative pressure, and the transverse corrugated liquid bladder component will supply the liquid to the inside of the spherical bearing liquid bladder component through the supply hose.

[0012] Furthermore, during the expansion of the spherical liquid-bearing bladder component, the outer isolation movable component is pushed to move under force, and the isolation movable component is moved outward along the outer side of the ore-carrying vehicle base through the nested docking component, which clears obstacles in its operation and avoids excessive vibration contact from affecting the safety of the lithium battery component.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This explosion-proof lithium battery trackless ore transport vehicle for non-coal underground mines is equipped with an explosion-proof pressure relief structure. By guiding the explosion-proof pressure relief structure, the safety status of the lithium battery components is controlled. As the transmission wheel component drives the ore transport vehicle base to move in the mine tunnel, the docking eccentric wheel connected to its axle end will reciprocate and apply pressure to the contacting nested component. The contact nested component drives the fitting piston component to apply lateral pressure along the inner side of the liquid storage pre-reservation component. The liquid storage pre-reservation component with internal negative pressure will supply atomized liquid to the outer side of the sponge isolation layer at the lower end of the lithium battery component through the supply spray pipe component. This ensures that the temperature at the lower end of the lithium battery component is constant and avoids excessive drying. It solves the problems of complex underground mining environment, such as dust, large temperature changes, and strong impact loads. It prevents the lithium battery component, as a high-energy object, from thermal runaway in the confined space underground and ensures its overall safety. Furthermore, in conjunction with the continuous supply of spray pipe components, dust suppression operations are simultaneously achieved to prevent dust from affecting the operating status of the equipment. Through the design of a high-safety explosion-proof battery system, the chassis and power system of the vehicle are integrated to achieve zero-emission, high-safety, and high-efficiency operation of underground transportation. Furthermore, a guiding and protective structure is provided to control the forward movement of the ore-carrying vehicle base. As the contact force of the mating eccentric wheel causes the nested component to reciprocate along the inner side of the liquid storage pre-reserved component, the transverse corrugated liquid bladder component that is mated with its outer side will be under negative pressure. This allows the transverse corrugated liquid bladder component to supply liquid into the spherical bearing liquid bladder component through the supply hose. The reciprocating supply and deformation of the spherical bearing liquid bladder component will push the outer isolation movable component to bear force, causing the isolation movable component to reciprocate outward along the outer side of the ore-carrying vehicle base through the nested docking component. This clears obstacles during the operation and avoids excessive vibration from affecting the safety of the lithium battery components. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-9 This invention provides the following technical solution: an explosion-proof lithium battery trackless mining vehicle for non-coal underground mines. To address the problems of complex environments in non-coal underground mines, such as pervasive dust, large temperature variations, and intense impact loads, and the potential for disastrous consequences and safety hazards if lithium-ion batteries, as high-energy materials, experience thermal runaway in confined underground spaces, the invention discloses the following: a lithium battery component 2 is installed on the inner side of the mining vehicle base 1, and a transmission wheel component 3 is installed on the outer side of the mining vehicle base 1, supplying power to the transmission wheel component 3 via the lithium battery component 2; a liquid storage pre-reservoir component 5 is installed on the outer side of the mining vehicle base 1, and a docking eccentric wheel 4 is installed at the shaft end of the transmission wheel component 3, with the outer side of the docking eccentric wheel 4 corresponding to the outer side of the liquid storage pre-reservoir component 5; an explosion-proof pressure relief structure is provided between the mining vehicle base 1 and the liquid storage pre-reservoir component 5, and the safety status of the lithium battery component 2 is controlled by guiding the explosion-proof pressure relief structure.

[0018] The explosion-proof pressure relief structure is equipped with a fitting piston 6, which is nested and connected to the inner side of the liquid storage pre-reserved part 5. A contact nesting part 7 is fixedly connected to the outer side of the fitting piston 6, and the outer side of the contact nesting part 7 corresponds to the outer side of the docking eccentric wheel 4. A return spring 8 is fixedly connected to the outer side of the fitting piston 6, and the return spring 8 is connected to the inner side of the liquid storage pre-reserved part 5. A supply spray pipe component 9 is provided through the outer side of the liquid storage pre-reserved part 5, and the outer side of the supply spray pipe component 9 extends to the base of the ore transport vehicle. At the lower end of body 1, and on the inner wall of the spray pipe component 9, a flexible material bonding layer 10 is symmetrically provided. A sponge isolation layer 16 is provided between the lower end of the lithium battery component 2 and the ore transport vehicle base 1. The transmission wheel component 3 drives the docking eccentric wheel 4 to rotate in a circular motion. When the outer side of the docking eccentric wheel 4 moves to contact the outer end of the contacting nest 7, the pressed contacting nest 7 drives the bonding piston 6 to move along the inner side of the liquid storage pre-reserved component 5. The liquid storage pre-reserved component 5 forms a bond with the bonding piston 6 through the return spring 8. The liquid storage pre-reservation component 5, which forms an elastic support structure and has internal negative pressure, is supplied to the outside of the sponge isolation layer 16 through the supply spray pipe component 9 to form an atomized supply. The transmission wheel component 3 drives the ore car base 1 to move in the mine tunnel. The docking eccentric wheel 4, which is connected to its shaft end, will reciprocate and press against the contacting nested component 7. The contacting nested component 7 will drive the fitting piston component 6 to apply lateral pressure along the inner side of the liquid storage pre-reservation component 5. The liquid storage pre-reservation component 5 with internal negative pressure will supply to the lithium battery component 2 through the supply spray pipe component 9. The outer side of the sponge isolation layer 16 at the end forms an atomized liquid supply, thereby ensuring a constant temperature at the lower end of the lithium battery component 2 and avoiding excessive drying. This solves the problems of complex underground mining environments, such as dust, large temperature changes, and strong impact loads. It also prevents the lithium battery component 2, as a high-energy object, from experiencing thermal runaway in the confined space underground. Through the design of a high-safety explosion-proof battery system, the entire vehicle chassis and power system are integrated to achieve zero-emission, high-safety, and high-efficiency operation in underground transportation.

[0019] Example 2: Based on Example 1, a guide protection structure is also disclosed, the specific structure of which is as follows: The front end of the ore transport vehicle base 1 is provided with a guide and protection structure, which controls the forward movement of the ore transport vehicle base 1. The guiding and protective structure is equipped with a transverse corrugated liquid bladder component 11, which is located on the outside of the contact nesting member 7. The other side of the transverse corrugated liquid bladder component 11 is connected to the outside of the liquid storage pre-reservation member 5. A supply hose 12 is provided on the outside of the transverse corrugated liquid bladder component 11, and the supply hose 12 passes through and connects along the inner side of the ore car base 1. A nested docking member 15 is nested at the front end of the ore car base 1, and an isolation movable member 14 is fixedly connected to the outside of the nested docking member 15. A spherical bearing liquid bladder component 13 is connected to the inner side of the isolation movable member 14, and the outer side of the spherical bearing liquid bladder component 13 is connected to the front end of the ore car base 1. The spherical bearing liquid bladder component 13 is also connected to the end of the supply hose 12. As the contact nesting member 7 moves along the inner side of the liquid storage pre-reservation member 5, the transverse corrugated liquid bladder component 11 connected to it will be under negative pressure, and the transverse corrugated liquid bladder component 11 will be supplied with liquid. The hose 12 supplies liquid to the spherical liquid-bearing bladder component 13. During the expansion of the spherical liquid-bearing bladder component 13, the outer isolating movable component 14 is pushed and moved by force. The isolating movable component 14 moves outward along the outer side of the mining car base 1 through the nested docking component 15. The contact force of the mating eccentric wheel 4 on the mating nesting component 7 moves back and forth along the inner side of the liquid storage reserved component 5. The transverse corrugated liquid bladder component 11 connected to its outer side will be negatively pressured, so that the transverse corrugated liquid bladder component 11 supplies liquid to the spherical liquid-bearing bladder component 13 through the supply hose 12. The reciprocating supply of the deformed spherical liquid-bearing bladder component 13 will push the outer isolating movable component 14 to be pushed outward along the outer side of the mining car base 1 through the nested docking component 15. This clears obstacles in the process of operation and avoids excessive vibration from affecting the safety of the lithium battery component 2.
