Technical Field
[0001] This utility model relates to the field of mine transportation technology, and in particular to a 3-ton articulated transport vehicle for mines. Background Technology
[0002] A mine tunnel is a man-made underground passage, usually located within rock strata or ore bodies. Its geological structure stability is greatly affected by the surrounding geological conditions. The geological structure and rock properties of different ore deposits determine the direction, slope, and cross-sectional shape of the mine tunnel. The 3-ton articulated transport vehicle for mine tunnels is a specially designed articulated transport vehicle with a rated load capacity of 3 tons for underground mine roadway transportation operations. It can operate stably in complex mine environments, such as narrow, rugged, humid, and dusty conditions, and undertakes the important task of transporting mined ore, coal, and other materials from the working face to designated locations. It is a key link in the mine production process.
[0003] In existing technologies, some mine roadways are characterized by being low and narrow, with extremely limited turning radii. In such roadway environments, transport vehicles with a rated load capacity of 3 tons are unable to maneuver and maneuver flexibly due to their large size and insufficient steering flexibility. They are often restricted by the narrow space and may even get stuck in the roadway. This not only leads to the interruption of transport tasks but also causes delays in a series of subsequent production processes, seriously affecting overall production efficiency and causing many inconveniences and losses to mine production. Therefore, it is necessary to improve the 3-ton articulated transport vehicle for mine roadways to solve the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please see Figure 1 - Figure 7This utility model provides an embodiment of a 3-ton articulated transport vehicle for mining tunnels, including a transport vehicle head 1, a mounting frame 21 fixedly connected to the transport vehicle head 1, a rotating shaft 22 rotatably connected inside the mounting frame 21, a support frame 23 fixedly connected to the rotating shaft 22, a transport carriage 27 fixedly connected to the inner side of the support frame 23, a loading and unloading assembly disposed on the transport carriage 27 for loading and unloading goods inside the transport carriage 27, a rotating frame 24 rotatably connected inside the support frame 23, a tire 25 rotatably connected to the rotating frame 24, a first movable rod 26 rotatably connected to the rotating frame 24, and a fixed frame 28 fixedly connected to the rotating shaft 22. The second movable rod 29 is rotatably connected to the fixed frame 28. The end of the first movable rod 26 away from the rotating frame 24 is rotatably connected to the mounting frame 21. It rotates through the support frame 23, and then the first movable rod 26 and the second movable rod 29 are used to synchronously control the steering of the four sets of rotating frames 24, so as to facilitate the control of the direction of the four sets of tires 25, improve flexibility, improve the stability of shuttle, improve the overall conveying efficiency, and improve the practicality of the conveyor. The loading and unloading component makes it easy to open and close the door panel 32, so as to facilitate the loading and unloading of goods inside the conveyor compartment 27, improve the loading and unloading efficiency, and improve the conveying stability of the conveyor compartment 27.
[0026] Please see Figure 2 - Figure 4In this embodiment, two sets of fixed frames 28 are provided, symmetrically distributed on the rotating shafts 22 on both sides. Both ends of the second movable rod 29 are rotatably connected to the interior of the two sets of fixed frames 28, allowing the rotating frames 24 on both sides to rotate synchronously. This facilitates control of the direction of the four sets of tires 25 and improves the stability of the conveying process. Four sets of first movable rods 26 are provided, symmetrically distributed in pairs on the rotating frames 24 and mounting frame 21 on both sides, maintaining the synchronous turning of the rotating frames 24 on both sides and improving stability. A first U-shaped seat 210 is fixedly connected to the mounting frame 21, and a second U-shaped seat 211 is fixedly connected to the support frame 23. A first rotating block 212 is rotatably connected inside the second U-shaped seat 211, and a second rotating block 214 is rotatably connected inside the first U-shaped seat 210. A telescopic connection is fixedly connected between the second rotating block 214 and the first rotating block 212. The hydraulic telescopic rod 213 extends and retracts, causing the support frame 23 to rotate. The first movable rod 26 and the second movable rod 29 then synchronously control the steering of the four sets of rotating frames 24, facilitating the control of the direction of the four sets of tires 25, improving flexibility, shuttle stability, overall conveying efficiency, and the practicality of the conveyor vehicle. The first U-shaped seat 210 has a matching groove at the corresponding position of the second rotating block 214, allowing the second rotating block 214 to rotate within the groove. Similarly, the second U-shaped seat 211 has a matching groove at the corresponding position of the first rotating block 212, allowing the first rotating block 212 to rotate within the groove of the second U-shaped seat 211. This ensures that when the hydraulic telescopic rod 213 extends and retracts, the first U-shaped seat 210 and the second U-shaped seat 211 do not limit the movement of the second rotating block 214 and the first rotating block 212, thus improving stability.
[0027] Please see Figure 5 - Figure 7In this embodiment, the loading and unloading assembly includes a rotating rod 31 rotatably connected inside the conveyor carriage 27, a door panel 32 fixedly connected to the rotating rod 31, a fixed bracket 33 fixedly connected to the outside of the conveyor carriage 27, a locking pin 34 movably connected inside the fixed bracket 33, a lever 35 fixedly connected to the locking pin 34, a rotating disk 36 rotatably connected to the locking pin 34, a spring 37 fixedly connected between the rotating disk 36 and the fixed bracket 33, a limiting disk 38 fixedly connected to the locking pin 34, and a limiting frame 39 fixedly connected to the outside of the conveyor carriage 27. The locking pin 34 penetrates the conveyor carriage 27 and engages inside the door panel 32. The lever 35 is disposed inside the limiting frame 39. The loading and unloading assembly facilitates... The door panel 32 is opened and closed to facilitate loading and unloading of goods inside the conveyor carriage 27, improving loading and unloading efficiency and conveying stability. The limiting frame 39 has a matching groove at the corresponding position of the lever 35. The lever 35 is set in the groove of the limiting frame 39 so that when the tire 25 is stuck in the groove of the limiting frame 39, it limits the locking pin 34 and releases the limiting of the door panel 32, thereby facilitating the opening and closing of the door panel 32 and improving the convenience of loading and unloading goods. The door panel 32 has a matching round hole at the corresponding position of the locking pin 34. The locking pin 34 is engaged in the round hole of the door panel 32 to fix and release the door panel 32, thereby improving the conveying stability.
[0028] During operation, by moving the levers 35 on both sides, the latches 34 on both sides are moved outward, compressing the spring 37. Then, by rotating the levers 35, they are positioned in the corresponding position of the slot in the limit bracket 39. At this time, the compressed spring 37 returns to its original position, locking the lever 35 in the slot of the limit bracket 39, thus releasing the restriction on the door panel 32. The door panel 32 is then rotated to facilitate loading and unloading, improving loading and unloading efficiency. After loading and unloading, the door panel 32 is rotated to position the round hole of the door panel 32 in the corresponding position of the latch 34. Then, the lever 35 is pulled out of the slot in the limit bracket 39. Rotating the lever 35 causes the compressed spring 37 to reset the latch 34, locking it inside the round hole of the door panel 32. This design allows the door panel 32 to cover the conveyor carriage 27, improving its practicality. The driver enters the transport head 1 and controls it, moving the conveyor carriage 27 to facilitate the transport of goods. During transport, the hydraulic telescopic rod 213 extends and retracts, causing the support frame 23 to rotate and connect to the mounting frame 21 via the rotating shaft 22, thus rotating the conveyor carriage 27. At this time, the first movable rods 26 on both sides synchronously adjust the angle of the rotating frames 24 on both sides, and the second movable rod 29 synchronously adjusts the angle of the tires 25 on the support frames 23 on both sides, facilitating flexible steering during the transport of goods and improving transport efficiency.
[0029] Through the above steps, the support frame 23 is rotated, and the first movable rod 26 and the second movable rod 29 are used to synchronously control the steering of the four sets of rotating frames 24, making it easier to control the direction of the four sets of tires 25, improving flexibility, improving the stability of shuttle, and improving the overall conveying efficiency. This solves the problem that transport vehicles with a rated load capacity of 3 tons are unable to flexibly turn and shuttle in the alley due to their large body size and insufficient steering flexibility.
