Description

Technical Field

[0001] The present invention relates to the technical field of conveying mining vehicles, in particular to a hydraulic side-dumping mining vehicle. Background Art

[0002] In the field of mining transportation, the unloading process of traditional mine cars usually relies on one-way dumping or manual assisted operation, which has problems such as low unloading efficiency and insufficient flexibility. For example, most mine cars can only achieve one-way dumping. When unloading in different directions is required, the vehicle head must be turned or the ore must be manually transported, resulting in a cumbersome and time-consuming operation process. In addition, the wheel spacing of existing mine cars is mostly fixed, which makes it difficult to adapt to transportation scenarios with different track widths, and the equipment has poor versatility. Moreover, the side-over unloading of existing mine cars is mostly achieved by setting rollers to contact the sloped track, and performing one-way rollover as it moves. Its flexibility is poor, which further restricts the efficiency and economy of mine transportation. Summary of the Invention

[0009] Preferably, the driving structure includes a pair of first brackets, a second electric slide rail, a pair of second brackets, a slide, a movable seat, a toggle seat and a hydraulic cylinder; one end of a pair of the brackets are symmetrically arranged on the upper wall of the rear end of the frame, the second electric slide rail is fixedly arranged between the first brackets, and the second electric slide rail is located on the rear side of the force-bearing arm, one end of a pair of the second brackets are symmetrically arranged on the left and right ends of the frame and are located on the rear side of the vehicle plate, the slide is fixedly arranged between the other end of the second bracket, and the slide is located in front of the second electric slide rail, a movable groove is opened through the middle of the second bracket, the movable seat is movably embedded in the slide, the toggle seat is concave, the toggle seat is fixedly arranged on the movable seat, and the toggle seat is movably clamped on the force-bearing roller, one end of the hydraulic cylinder is movably arranged on the second electric slide rail, and the telescopic end of the hydraulic cylinder is movably connected to the movable seat, and the hydraulic cylinder can tilt left or right.

[0010] Preferably, the shifting seat moves left and right and applies force to the force-bearing roller.

[0011] Preferably, the vehicle plate is subjected to force flipping by limiting contact between a pulley and one end of the wheel rail.

[0012] Preferably, the length of the wheel track is greater than the distance between the pulleys.

[0013] The hydraulic side-dumping mining car proposed by the present invention, compared with the traditional side-dumping mining car that relies on rollers and sloped tracks, includes: a driving structure that can realize the turning power by driving the translation movement to contact the force-bearing roller through the hydraulic cylinder; a vehicle body structure that realizes the bidirectional turning of the vehicle plate by shielding the vehicle plate and pulleys through the wheel rail, and after the pulley on one side of the vehicle plate is shielded by one end of the wheel rail, it turns with the force of the force-bearing roller; a loading and unloading structure that automatically opens the side box plate for unloading and stores force through the spring during the side-dumping, and assists the side box plate in returning to close the cargo box through the spring. The beneficial effects are: 1. Combining hydraulic drive with mechanical transmission to achieve precise and controllable two-way flipping: This solution converts the horizontal hydraulic power into flipping power through the tilt drive of the hydraulic cylinder and the force applied to the toggle seat. It does not rely on the track slope and can complete unloading on a horizontal site, which is more flexible to adapt to different scenarios. The two-way dumping switch is flexible: the second electric slide rail in the drive structure adjusts the tilt direction of the hydraulic cylinder, and cooperates with the toggle seat to apply force to the left and right of the force roller to realize the dumping of the cargo box to any direction on the left or right. This solves the problem that traditional mine cars need to turn the head of the car for one-way unloading, and improves the efficiency of operations in narrow spaces.

[0014] 2. The interlocking locking mechanism of gravity drive and spring force storage realizes automatic unloading and resetting: the dumping component opens automatically: when the cargo box is turned over, the side box plates are automatically opened by the gravity of the ore. At the same time, the lower pressure seat of the reset component is compressed and forced by the tooth arm and gear transmission. No additional power source is required, and the unloading process is efficient and energy-saving; after unloading, the spring releases the stored force to push the lower pressure seat upward, and the tooth arm is reset through the engagement of the tooth rod and gear, so that the side box plates are automatically closed to cover the cargo box, forming a "dumping-force storage-reset" linkage closed loop, avoiding the problems of traditional manual reset or jamming due to rust, and improving the reliability of continuous operation.

[0015] 3. Adjustable wheelbase to adapt to different tracks: The first electric slide in the car body structure drives the wheel frame to move, which can automatically adjust the wheel spacing according to the track width, solving the pain point that the fixed wheelbase of traditional mining cars cannot adapt to different tracks and reducing equipment replacement costs.

[0016] 4. The linkage mechanism replaces manual operation: the dumping and resetting processes are completed by mechanical transmission, gravity and hydraulic pressure. There is no need for manual assistance to open and close the side box panels or adjust the flipping direction, which reduces labor intensity.

[0017] 5. Double improvement in safety and efficiency: Two-way dumping avoids secondary handling: Unloading can be done at any position on both sides of the mine tunnel, reducing the ore transfer process and shortening the transportation cycle; the spring force storage of the reset component engages with the gear to form a mechanical lock, ensuring that the cargo box will not automatically open due to bumps during driving, thereby improving transportation safety.

[0023] More specifically, when the distance between the wheelsets 16 of the mine car needs to be adjusted, the first electric slide 14 drives the first slide to move left and right, driving the wheel frame 15 to move synchronously, thereby changing the lateral distance between the two pairs of wheelsets 16, so that the mine car can travel on tracks with different gauges, significantly improving the environmental adaptability of the equipment; when the toggle seat 36 of the driving structure 3 pushes the force roller 10, the force arm 19 drives the car plate 17 to flip with the end contact point of the pulley 18 and the wheel rail 12 as the fulcrum, realizing the side unloading action of the cargo box 21, wherein the arc-shaped end of the wheel rail 12 plays a limiting role on the pulley 18, ensuring that the flipping process is stable and controllable.

[0024] See also Figure 4 and Figure 5 As shown, as a preferred embodiment, further, the loading and unloading structure 2 includes a cargo box 21, a pair of tipping components 22 and a pair of reset components 23; the cargo box 21 is a box body without an upper wall and left and right side walls, the cargo box 21 is fixedly arranged on the upper wall of the vehicle plate 17, a pair of tipping components 22 are symmetrically arranged on the left and right sides of the cargo box 21, a pair of reset components 23 are symmetrically arranged on the front side walls of the cargo box 21, and the reset components 23 are symmetrical with the tipping components 22; the loading and unloading components are automatically started by gravity after the cargo box 21 is turned over, and the reset component 23 is driven to accumulate force by the start of the tipping component 22, and the tipping component 22 can be effectively reset by the reset component 23.

[0025] More specifically, when the vehicle plate 17 is flipped to the left by the driving structure 3, the gravity of the ore in the cargo box 21 pushes the left side box plate 222 to rotate outward around the flip claw 221, and the side box plate 222 pulls the tooth arm 225 to flip around the limit frame 224; the tooth arm 225 remains engaged with the gear 223, driving the gear 223 to rotate, and the gear rod 235 at the front end of the gear 223 moves downward by the driving force of the gear 223, pushing the lower pressure seat 233 to compress the spring 234 along the slide rod 232, so that the reset assembly 23 accumulates force.

[0026] See also Figure 4 and Figure 5 As shown, as a preferred embodiment, further, the dumping assembly 22 includes a pair of flip claws 221, side box plates 222, gears 223, limit frames 224 and tooth arms 225; one end of the pair of flip claws 221 is symmetrically arranged on the upper wall of the left end of the cargo box 21, the side box plates 222 are movably arranged between the other ends of the flip claws 221, and the side plates block the left side of the cargo box 21, the gear 223 is movably arranged on the front side wall of the cargo box 21 and close to the bottom end of the side box plates 222, the limit frame 224 is movably arranged on the front side of the cargo box 21 and is located above the gear 223, and one end of the tooth arm 225 movably passes through the limit frame 224, and The tooth arm 225 is meshed with the rear end of the gear 223, and the other end of the tooth arm 225 is tilted and movably connected to the front side wall of the side box plate 222. The tooth arm 225 can be flipped to a certain angle through the limit frame 224, and the tooth arm 225 is continuously meshed with the gear 223; the tooth arm 225 is connected to the side box plate 222, and with the help of the force of the gear 223 and the reset component 23, the side box plate 222 is driven to close and block the cargo box 21. When the cargo box 21 is flipped, the side box plate 222 is forced to open and pull the tooth arm 225. The tooth arm 225 flips and moves with the help of the limit frame 224, driving the gear 223 to rotate to realize the power storage of the reset component 23.

[0027] More specifically, the dumping assembly 22 realizes the automatic drive of the unloading process through the linkage design of "side box plate 222 gravity opening - tooth arm 225 gear 223 transmission - reset assembly 23 force storage", without the need for additional hydraulic or electric control; the cooperation between the tooth arm 225 and the limit frame 224 ensures the accuracy of the transmission trajectory, and the meshing structure of the gear 223 makes the force storage process of the reset assembly 23 smooth and controllable, providing a power basis for the subsequent automatic reset of the side box plate 222, effectively solving the problem of manual reset of traditional mine cars after unloading, and improving loading and unloading efficiency and equipment reliability.

[0028] See also Figure 4 and Figure 5As shown, as a preferred solution, further, the reset assembly 23 includes a bracket 231, a slide bar 232, a lower pressure seat 233, a spring 234 and a gear rod 235; the bracket 231 is fixedly arranged on the front side of the cargo box 21 and close to the gear 223, a pair of slide bars 232 are symmetrically arranged on the bracket 231, the lower pressure seat 233 is movably sleeved on the slide bar 232, the spring 234 is fixedly arranged between the lower pressure seat 233 and the bracket 231, one end of the insertion rod is fixedly arranged on the middle of the upper wall of the lower pressure seat 233, and the insertion rod is meshed with the front end of the gear 223, and the gear rod 235 is located on the front side of the gear arm 225; the gear 223 is rotated to drive the gear rod 235 to be forced to descend, and the lower pressure seat 233 is lowered at the upper limit of the slide bar 232 to compress the spring 234 to store force.

[0029] More specifically, the reset assembly 23 converts the kinetic energy of the dumping assembly 22 during the unloading process into the elastic potential energy of the spring 234 through a closed-loop design of "gear 223 transmission - spring 234 storage - energy release and reset." This allows the side box plate 222 to be automatically reset without the need for an additional power source. The limiting structure of the slide bar 232 and the lower pressure seat 233 ensures a smooth and precise reset process, avoiding the jamming problem caused by shaking during the reset of the traditional spring 234 and improving the reliability of the continuous operation of the mine car. In addition, the meshing transmission between the gear rod 235 and the gear 223 can amplify the reset torque of the spring 234, forming a mechanical lock when the side box plate 222 is closed, preventing accidental opening during driving and enhancing transportation safety.

[0030] See also Figure 6 and Figure 7As shown, as a preferred embodiment, further, the driving structure 3 includes a pair of first brackets 31, a second electric slide rail 32, a pair of second brackets 33, a slide 34, a movable seat 35, a toggle seat 36 and a hydraulic cylinder 37; one end of a pair of brackets are symmetrically arranged on the upper wall of the rear end of the frame 11, the second electric slide rail 32 is fixedly arranged between the first brackets 31, and the second electric slide rail 32 is located on the rear side of the force arm 19, one end of a pair of second brackets 33 are symmetrically arranged on the left and right ends of the frame 11 and on the rear side of the vehicle plate 17, the slide 34 is fixedly arranged between the other ends of the second brackets 33, and the slide 34 is located in front of the second electric slide rail 32, a movable groove is opened through the middle of the second bracket 33, and the movable seat 35 is movably embedded In the slide 34, the toggle seat 36 is concave, and the toggle seat 36 is fixedly set on the moving seat 35, and the toggle seat 36 is movably clamped on the force roller 10. One end of the hydraulic cylinder 37 is movably set on the second electric slide 32, and the telescopic end of the hydraulic cylinder 37 is movably connected to the moving seat 35. The hydraulic cylinder 37 can tilt to the left or right; the second electric slide 32 drives one end of the hydraulic cylinder 37 to move left and right, and the tilt direction of the hydraulic cylinder 37 is adjusted to change the moving direction of the moving seat 35 in the slide 34. The toggle seat 36 is driven by the moving seat 35 to move to apply force to the force roller 10, and with the help of the rotation of the force roller 10, the force arm 19 drives one end of the car plate 17 to be forced to flip in the wheel rail 12 through the pulley 18.

[0031] More specifically, the drive structure 3 breaks through the limitation of traditional mine cars relying on sloped tracks through the design of "electric slides adjusting the tilt direction of the hydraulic cylinder 37 and converting the hydraulic thrust into a turning torque", and can realize two-way turning and unloading; the coordinated control of the electric slides and the hydraulic cylinder 37 realizes stepless switching of the turning direction, adapting to the multi-directional unloading needs of narrow mine tunnels; the mechanical transmission chain is simple and efficient, reducing the complex piping layout of the hydraulic system, reducing maintenance costs, and at the same time improving the reliability and safety of equipment operation.

[0032] As a preferred solution, further, the shifting seat 36 moves left and right and applies force to the force-bearing roller 10 .

[0033] As a preferred solution, further, the vehicle plate 17 is forced to flip over by limiting contact with one end of the wheel rail 12 through the pulley 18.

[0034] As a preferred solution, further, the length of the wheel rail 12 is greater than the spacing between the pulleys 18, so as to enable the vehicle plate 17 to be flipped and exchanged left and right.

[0035] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0036] S1. First, the equipment is staggered by the adapter 13 on both sides of the frame 11, which can be connected through relative activities for multiple mine cars to move on the track; S2 body structure 1 of the wheelset 16, the wheel frame 15 is driven by the first electric slide 14 to adjust the spacing to achieve the spacing adjustment of the wheelset 16, prompting the wheelset 16 to be used for rails of different widths; the frame 11 moves on the track through the wheel rail 12; S3. When the frame 11 moves to the corresponding position, the hydraulic cylinder 37 in the control drive structure 3 is extended. Through the extension of the hydraulic cylinder 37 and the movable connection, the movable seat 35 is driven to slide and translate within the carriage 34 between the second brackets 33. The translation of the movable seat 35 drives the toggle seat 36 to move and apply force to the load roller 10; S4. When the force-bearing roller 10 is subjected to force, the force is transmitted to the force-bearing arm 19 and drives the vehicle plate 17 to move with the help of the pulley 18, prompting the pulley 18 to move to the limit position at one end of the wheel rail 12. Then, as the force-bearing roller 10 moves, when the vehicle plate 17 cannot move horizontally, the force-bearing roller 10 is forced to rotate in the toggle seat 36, and with the help of the force-bearing arm 19, the vehicle plate 17 is forced to be limited to one end of the wheel rail 12 and flip around the middle of the pulley 18. When the force-bearing roller 10 rotates, as the toggle seat 36 moves horizontally and the vehicle plate 17 flips, the force-bearing arm 19 also flips relatively and drives the force-bearing roller 10 to descend in the toggle seat 36. S5. By flipping the car plate 17, the loading and unloading structure 2 is turned over and dumped; that is, when the cargo box 21 is flipped and tilted, the gravity of the cargo and the side box plate 222 in the dumping assembly 22 is automatically measured between the flip claws 221 and the cargo box 21 is flipped outward to open, and unloading can be achieved; S6. When the side box panel 222 is flipped open, the flipping of the side box panel 222 drives the tooth arm 225 to move within the limit frame 224 and flip around the gear 223 with the help of the limit frame 224. The movement of the tooth arm 225 drives the gear 223 to rotate. Since the gear 223 is in contact with the reset assembly 23, the rotation of the gear 223 drives the gear rod 235 to be forced downward, that is, the lower pressure seat 233 is driven to descend under the limit of the two slide bars 232 on the bracket 231, and the compression spring 234 is compressed to store force. When the side box panel 222 is flipped and reset as the cargo box 21 is flipped and reset, the side box panel 222 is reset and closed with the help of the stored force of the spring 234. S7. Since the vehicle plate 17 is located between the wheel rails 12 and the spacing between the pulleys 18 is smaller than the length of the wheel rails 12, the direction of one end of the hydraulic cylinder 37 can be adjusted by driving the second electric slide rail 32 on the first bracket 31. By changing the tilt direction of the hydraulic cylinder 37, the moving seat 35 can drive the toggle seat 36 to change its moving direction, thereby changing the direction in which the toggle seat 36 applies force to the force roller 10, and finally changing the flipping direction of the vehicle plate 17 in the wheel rails 12 and changing the rollover direction of the cargo box 21, thereby achieving unloading in different directions.
