Description

Technical Field

[0002] Currently, when producing coal underground, it is necessary to transport the mined coal and the materials needed for coal mining. Therefore, battery-powered locomotives are used for transportation underground. Battery-powered locomotives are a type of traction equipment for mining rail vehicles. They use the friction between the wheels and the rail surface to make the locomotive run on the track. Traditionally, battery-powered locomotives are operated manually to control them in case of emergencies. However, due to the limitations of the underground mining environment and the fatigue of manual operation, driverless battery-powered locomotives have been adopted, which greatly improves the automation level of ore transportation.

[0003] The existing unmanned driving assistance system for coal mine battery locomotives faces the following challenges: Due to the harsh underground environment and the tendency for ore to fall onto the track surface during transport, the ore causes friction on the locomotive wheels, hindering its movement. Current solutions involve regular manual cleaning, which increases labor intensity. Secondly, the track surface is prone to accumulating impurities in the mine environment. Over time, these impurities, when exposed to water, can form hard deposits on the track surface, causing wear on the wheels and reducing the locomotive's speed. Summary of the Invention

[0014] The beneficial effects of this invention are: (1) Due to the harsh environment in the mine and the fact that the ore on the battery locomotive is prone to fall onto the rail surface during transportation, the ore on the rail surface will cause friction on the wheels of the battery locomotive, which will hinder the movement of the coal mine battery locomotive. The present invention uses a brush assembly to generate friction between the first gear and the side of the rail during the movement of the locomotive, thereby transferring the kinetic energy of the friction to the pulley rod and the limit rod, and then indirectly to the brush rod. The brush on the brush rod is used to automatically clean the coal fragments on the rail surface, improve the degree of mechanical automation, and have a strong cleaning effect.

[0015] (2) In the mine environment, many impurities are likely to appear on the ground rail. Over a long period of time, these impurities will easily form hard materials on the rail surface when they come into contact with water. This invention uses the kinetic energy of the electric locomotive to move the inclined plate on the rail surface so as to push it when it encounters hard materials. Moreover, the inclined plate designed in this invention is inclined so that the pushed hard materials can quickly separate from both sides, thereby increasing the speed of the electric locomotive.

[0016] (3) The present invention designs a first drive assembly to drive the connecting gear to move the front and rear rack plates in opposite directions, thereby indirectly driving the brush discs on both sides to move in opposite directions. The present invention designs a spring limit rod and a sliding limit rod, which is beneficial to provide sufficient shock absorption when the pulley ball encounters a fault, and can also drive normally on curved ground rails, thereby improving the mechanization of the present invention. The present invention designs a second drive assembly, which uses the kinetic energy of the drive motor to transmit the total gear and the slide rail plate, thereby realizing the synchronous movement of the first drive assembly and the cleaning assembly, thereby improving the mechanization of the present invention.

[0017] (4) The present invention is designed with a reset spring, a limit rod, a cross groove seat, a cross protrusion seat, a brush rod, a pressing block, a connecting piece and a disassembly screw to realize the quick installation and disassembly of the brush disc. The present invention, by designing a spring rod, a pressing block seat, a first ball and a second ball, realizes the balancing and stabilizing effect of the brush disc during rotation, thereby improving the cleaning effect of the invention.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figures 1 to 3This invention provides an unmanned assisted driving system for a coal mine battery-powered locomotive: it includes a locomotive 1, a battery 2 installed on the top of the rear end of the locomotive 1, a sliding seat 3 connected to the front end of the locomotive 1 via a slide rail connection, a groove opened at the front end of the locomotive 1, and an electric push rod 4 for driving the sliding seat 3 to move up and down is installed in the groove, two fixed seats 31 are installed at the front end of the sliding seat 3, and a cleaning component 7 for cleaning hardware materials on the rail surface is installed at the front end of the two fixed seats 31.

[0023] As one embodiment of the present invention, such as Figure 3 and Figure 5 As shown, a brush assembly 5 for cleaning ore on the rail surface is installed at the front end of the two fixed seats 31. The brush assembly 5 includes a horizontal block 51, which is located on the left end of the fixed seat 31. A pair of vertical blocks 52 are provided at the bottom of the horizontal block 51 and the right end of the fixed seat 31. A concave block 53 is installed between the middle of the pair of vertical blocks 52. A pulley seat 54 is installed at the lower end of the lower vertical block 52. A pulley ball 55 is rotatably connected to the inner side of the pulley seat 54. A sleeve 56 is installed at the top of the pulley seat 54. A brush rod 57 is provided inside the sleeve 56. A brush disc 58 is installed in the middle of the brush rod 57 inside the concave block 53. The brush at the bottom of the brush disc 58 is a hard brush. A pressing block 59 is provided on the upper vertical block 52, and the pressing block 59 is sleeved on the top of the brush rod 57.

[0024] During operation, the two pulley balls 55 are pressed against the sides of the rail surface, and the brushes on the two brush discs 58 are pressed against the rail surface. When the locomotive 1 starts, the two pulley balls 55 and the sides of the ground rail generate friction, which causes the two pulley balls 55 to rotate. During the rotation of the pulley balls 55, the brush rods 57 and the brush discs 58 rotate synchronously. In this way, the brushes pressed against the rail surface rotate. The kinetic energy of the locomotive 1 is transferred to the pulley balls 55, and then the kinetic energy of the pulley balls 55 is transferred to the brush discs 58, thereby automatically cleaning the coal fragments on the rail surface and improving the level of mechanization.

[0025] As one embodiment of the present invention, such as Figure 5 , Figure 7 and Figure 8As shown, a vertical groove is provided on the opposite side of the upper concave block 53 and on the side corresponding to the pressing block 59. A connector 511, which is fixedly connected to the pressing block 59, is slidably provided in the vertical groove. A disassembly screw 512, which is threadedly connected to the connector 511, is rotatably connected to the top of the concave block 53. The top of the disassembly screw 512 is fixedly connected to the upper vertical block 52 through a connecting seat. A torsion cap is installed on the top of the connecting seat through the top of the disassembly screw 512. The middle part of the pulley ball 55 rotatably passes through the top of the pulley seat 54 and is equipped with a pulley rod 513. A limit groove is provided in the middle of the pulley rod 513, and a limit rod 514 is slidably provided in the limit groove. A cross groove seat 516 is installed on the top of the pulley rod 513, and a return spring 515 is sleeved on the outside of the pulley rod 513. The top of the cross groove seat 516 is closely attached to the cross protrusion 517. The top surface of the cross protrusion 517 is installed on the bottom of the brush rod 57. The sleeve 56 has disassembly grooves 518 on opposite sides. The protruding part of the cross protrusion 517 and the inner side of the cross groove seat 516 are both set to be inclined so that the cross protrusion 517 and the cross groove seat 516 can be quickly limited. Rubber pads are installed on the outer sides of the cross protrusion 517 and the cross groove seat 516 to improve the friction between the cross protrusion 517 and the cross groove seat 516, which makes the pulley ball 55 rotate stably.

[0026] When the brush disc 58 needs to be replaced, the rotation of the disassembly screw 512 is driven by the twisting of the torsion cap, thereby realizing the lifting and lowering movement of the connector 511 and the pressing block 59. This allows the brush disc 58 to be released from the restraint of the pressing block 59. Then, when the return spring 515 releases its elastic potential energy, the brush rod 57 is pushed upward. The brush disc 58 can then be bent and removed manually. At this time, the brush rod 57 disengages from the disassembly groove 518, thus achieving quick disassembly of the brush disc 58. When the brush disc 58 needs to be installed quickly, the cross-shaped protrusion 517 of the brush rod 57 is manually inserted into the disassembly groove 518. During the rotation of the brush rod 57, the cross-shaped protrusion 517 and the cross-shaped groove seat 516 enter a limited state. Then, the brush rod 57 on the top surface of the brush disc 58 is fitted into the pressing block 59. Finally, the pressing block 59 is moved downward by manually twisting the torsion cap, thus achieving quick installation of the brush disc 58 and improving the efficiency of disassembly and installation of the brush disc 58.

[0027] As one embodiment of the present invention, such as Figure 5 and Figure 6 As shown, a spring rod 521 is slidably connected to the middle of the opposite side of the concave block 53, a pressure block seat 522 is installed on the opposite side of the spring rod 521, a first ball bearing 523 is rotatably connected to the opposite side of the pressure block seat 522, a rotating groove adapted to the first ball bearing 523 is opened on the outer side of the brush disk 58, a second ball bearing 524 is rotatably connected to the top of the concave block 53, and a clearance groove adapted to the second ball bearing 524 is opened on the top of the brush disk 58.

[0028] During operation, as the brush disc 58 rotates, the first ball 523 and the second ball 524 roll and squeeze within the rotation groove and clearance groove on the brush disc 58, respectively. This improves the balance and rotational stability of the brush disc 58. The invention also facilitates the quick disassembly and installation of the brush disc 58 by designing a spring rod 521.

[0029] As one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 9 As shown, a first driving component 6 for driving the brush assembly 5 to move in opposite directions is installed on the top of the fixed base 31. The first driving component 6 includes a connecting gear 61. A gear groove is opened in the middle of the fixed base 31, and the connecting gear 61 is rotatably connected in the gear groove. The fixed base 31 has symmetrical sliding grooves at both ends of the connecting gear 61 that communicate with the gear groove. A rack plate 62 is connected in the sliding groove by a slide rail connection. A storage groove is opened on the inner side of the fixed base 31 at the opposite end of the rack plate 62 so that the rack plates 62 can move sufficiently in a limited manner during the rotation of the connecting gear 61. The opposite surfaces of the rack plates 62 mesh with the connecting gear 61 through gear teeth. A spring limiting rod 63 is installed on the opposite side of the rack plates 62. The spring limiting rod 63 designed in this invention is beneficial for preventing... When the anti-slip ball 55 encounters a fault on the rail surface, the two side pulley balls 55 can play a shock absorption role, thereby protecting the pulley ball 55. Sliding limit rods 64 are installed on both the left and right sides of the rear end of the fixed seat 31. The rear end of the horizontal block 51 is slidably connected to the sliding limit rod 64 on the left side, and the top of the vertical block 52 on the right side is slidably connected to the sliding limit rod 64. The front end of the right sliding seat 3 is equipped with a transmission seat 65. The top of the connecting gear 61 passes through the inner side of the transmission seat 65 through the connecting rod and is equipped with a first gear 66. The outer side of the first gear 66 is connected to a transmission belt 67, and the middle of the transmission belt 67 is meshed with a second gear 68. The top of the second gear 68 passes through the top of the transmission seat 65 through the connecting rod and is equipped with a main gear 69.

[0030] During operation, the main drive gear 69 rotates, causing the second gear 68 inside the transmission seat 65 to rotate. Then, under the action of the transmission belt 67, the first gears 66 on both sides rotate. At the same time, the connecting gear 61 rotates through the transmission of the connecting rod, thereby realizing that the two rack plates 62 move towards each other, so that the pulley balls 55 at both ends are in close contact with the side of the ground rail, improving the mechanization of the invention.

[0031] As one embodiment of the present invention, such as Figure 3As shown, the cleaning component 7 includes a ramp 71, the rear end of which is rotatably connected to the front end of the fixed base 31. A spring telescopic rod 72 is installed in the middle of the ramp 71, and a ramp 73 is installed on the front end of the ramp 71. The ramp 73 is triangular in shape, and both its left and right sides are inclined. By designing the ramp 73 with an inclined shape, the present invention allows the hardware material to be pushed onto the rail surface of the ramp 73 by the electric vehicle. After the hardware material is separated from the rail surface, it is detached from the two sides of the ramp 73, thereby improving the cleaning effect on the ground bend.

[0032] As one embodiment of the present invention, such as Figure 8 , Figure 9 and Figure 10 As shown, a second drive assembly 8 is mounted on the top of the fixed base 31 to drive the brush assembly 5 and the cleaning assembly 7 to move simultaneously. The second drive assembly 8 includes an L-shaped base 81. The vertical end of the L-shaped base 81 is mounted on the front end of the sliding base 3. A drive motor 82 is mounted on the horizontal end of the L-shaped base 81 via a motor mount. The output end of the drive motor 82 is connected to a drive screw 83. The rear end of the drive screw 83 is rotatably connected to a transmission base 65. A first gear plate 84 is mounted on the rear end of the drive screw 83. The top of the main gear 69 is equipped with a second gear plate 85 that meshes with the first gear plate 84. The front end of the drive screw 83 is threadedly connected to a connecting block 86. The bottom of the transmission seat 65 is equipped with a slide rail seat 87. The bottom end of the connecting block 86 is horizontally equipped with a slide rail plate 88 that is slidably connected to the slide rail seat 87. The middle part of the fixed seat 31 is fixedly connected to a torsion rod 89 by a wedge block 71. The middle part of the torsion rod 89 is equipped with a dangling gear 810. The outer side of the dangling gear 810 meshes with the gear teeth at the bottom of the slide rail plate 88.

[0033] During operation, the drive motor 82 drives the drive screw 83 to rotate, which in turn drives the first gear plate 84 connected to it to rotate. Subsequently, the second gear plate 85 drives the main gear 69 connected to it to rotate. At the same time, the drive screw 83 rotates, causing the connecting block 86 to move back and forth. Then, when the connecting block 86 moves back and forth, it causes the slide rail plate 88 connected to it to slide along the slide rail seat 87. Then, the gear teeth on the slide rail plate 88 drive the vertical gear 810 and the torsion rod 89 to rotate, thereby realizing the adjustment of the inclined blocks 71 on both sides to different angles. The design of this invention is conducive to the cooperation between the inclined plate 73 and the pulley ball 55, improving the cleaning effect of this invention.

[0034] As one embodiment of the present invention, such as Figure 1 , Figure 3 , Figure 10 and Figure 11As shown, a rotating circular part 691 is rotatably connected to the top of the transmission seat 65 and the right end of the main gear 69. A retaining seat 693 is rotatably connected to the top of the transmission seat 65 near the rotating circular part 691. A compression spring 692 is connected between the rotating circular part 691 and the retaining seat 693. A retaining block 694 is installed on the side of the retaining seat 693 near the main gear 69 and is engaged with the teeth of the main gear 69. A manual lever 695 is installed on the side of the retaining seat 693 away from the main gear 69. A moving groove is provided through the top of the L-shaped seat 81 and the side corresponding to the manual lever 695 to facilitate the rotation of the manual lever 695.

[0035] When the locomotive 1 travels rapidly on the ground rail, the pulley balls 55 on both sides will vibrate, which will cause the rack plate 62 and the connecting gear 61 to twist. The present invention limits the main gear 69 by setting the locking block 694 on the locking seat 693 and the pulling force of the rotating round part 691 and the compression spring 692 on the locking seat 693, thereby preventing the main gear 69 from slipping and improving the transmission stability and limiting effect of the present invention.

[0036] Working principle: This is used in an unmanned assisted driving system for a coal mine battery-powered locomotive. When in use: First: During the rotation of the drive screw 83 driven by the drive motor 82, the first gear plate 84 connected to it rotates. Then, the second gear plate 85 drives the total gear 69 connected to it to rotate. At the same time, during the rotation of the drive screw 83, the connecting block 86 moves back and forth. Then, when the connecting block 86 moves back and forth, the slide rail plate 88 connected to it slides along the slide rail seat 87. Then, the gear teeth on the slide rail plate 88 drive the vertical gear 810 and the torsion rod 89 to rotate, thereby realizing the adjustment of the inclined blocks 71 on both sides at different angles.

[0037] Second: The rotation of the main drive gear 69 drives the rotation of the second gear 68 inside the transmission seat 65. Then, under the action of the transmission belt 67, it drives the rotation of the first gears 66 on both sides. At the same time, the connecting gear 61 is driven to rotate through the transmission of the connecting rod, so that the two rack plates 62 move towards each other. When the pulley ball 55 abuts against the side of the ground rail, the brushes on the brush discs 58 on both sides abut against the rail surface. When the locomotive 1 starts, the pulley ball 55 on both sides and the sides of the rail surface generate friction, so that the pulley ball 55 on both sides rotates. During the rotation of the pulley ball 55, it drives the brush rod 57 and the brush disc 58 to rotate synchronously. In this way, the brushes abutting against the rail surface rotate. The kinetic energy of the locomotive 1 is transferred to the pulley ball 55, and then the kinetic energy of the pulley ball 55 is transferred to the brush disc 58, thereby automatically cleaning the coal fragments on the rail surface.

[0038] Third: During the rotation of the drive screw 83, the connecting block 86 moves back and forth. Then, when the connecting block 86 moves back and forth, it drives the slide rail plate 88 connected to it to slide along the slide rail seat 87. Then, the gear teeth on the slide rail plate 88 drive the vertical gear 810 and the torsion rod 89 to rotate, thereby realizing the adjustment of different angles of the inclined blocks 71 on both sides.

[0039] Fourth: When the brush disc 58 needs to be replaced, the rotation of the disassembly screw 512 is driven by the twisting of the torsion cap, thereby realizing the lifting and lowering movement of the connector 511 and the pressing block 59, so that the brush disc 58 is freed from the restraint of the pressing block 59. Then, when the return spring 515 releases its elastic potential energy, the brush rod 57 is pushed upward. Then, the brush disc 58 is bent and removed manually. At this time, the brush rod 57 is disengaged through the disassembly groove 518, thereby realizing the quick disassembly of the brush disc 58. When the brush disc 58 needs to be installed quickly, the cross convex seat 517 of the brush rod 57 is manually inserted into the disassembly groove 518. Then, during the rotation of the brush rod 57, the cross convex seat 517 and the cross groove seat 516 enter the limit state. Then, the brush rod 57 on the top surface of the brush disc 58 is placed in the pressing block 59. Then, the pressing block 59 is moved downward by manually twisting the torsion cap, thereby realizing the quick installation of the brush disc 58.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
