Description

Technical Field

[0001] This invention relates to the field of mining truck technology, and more specifically to a mining truck designed to prevent material leakage. Background Technology

[0002] In coal and other mineral resource extraction operations, mine cars typically operate in train formations, and gaps of a certain size inevitably exist between adjacent cars. Related technologies use herringbone covers fixed to adjacent cars to conceal these gaps. However, as... Figure 1 As shown, when the mine car is loading in the curved area, the curvature of the track will also cause the relative position between the cars to change, resulting in a large deviation on both sides of the gap between adjacent cars. This herringbone cover is difficult to accurately fit the shape and position of the gap and cannot effectively achieve the shielding effect. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a leak-proof mining car that can adapt to changes in the gap between two carriages when the mining car travels on curves, effectively preventing ore leakage.

[0004] The leak-proof mining car provided by the present invention includes two adjacent car sections. Each car section is equipped with a shielding assembly, which includes a rotating shaft, a shielding plate, and multiple slide rails. The rotating shaft extends along the width direction of the car section and is rotatably connected to it. The multiple slide rails are spaced apart on the rotating shaft along its axial direction. Each shielding plate has a first end and a second end arranged opposite to each other. The first end is provided with multiple sliding rods, which are slidably mounted on the slide rails one-to-one. The second end is provided with pin holes. The shielding plates of adjacent car sections are connected by connecting rods passing through the pin holes.

[0005] In summary, the leak-proof mining car provided by the present invention, through the setting of sliding rods and sliding rails, enables the shielding plate to always maintain the best fit with the gap between the car body, which can adapt to the change in the gap between the two car bodies 10 when the mining car is traveling on a curve, and effectively prevent ore leakage.

[0006] In some embodiments, the slide rail includes a guide sleeve with a hollow cavity inside, the sliding rod is movably inserted through the hollow cavity, and an elastic element is provided between the sliding rod and the guide sleeve.

[0009] In some embodiments, the shielding assembly further includes a second driver disposed on the carriage, the output of the second driver being connected to the rotating shaft, and the second driver being used to drive the rotating shaft to rotate relative to the carriage.

[0010] In some embodiments, the shielding assembly further includes a magnetic attractor disposed at a pin hole in the shielding plate. When the shielding plates of two adjacent carriages come into contact, the magnetic attractors on the two shielding plates attract each other to achieve positioning.

[0011] In some embodiments, the shielding assembly further includes a shock-absorbing pad, the shielding plate having a first wall and a second wall disposed opposite to each other, the shock-absorbing pad being disposed on the first wall and the magnetic attractor being disposed on the second wall.

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention provides a leakage-proof mining car, which includes two adjacent car sections 10. Each car section 10 is equipped with a shielding assembly 20, which includes a rotating shaft 21, shielding plates 22, and multiple slide rails 25. The rotating shaft 21 extends along the width direction of the car section 10 and is rotatably connected to it. The multiple slide rails 25 are spaced apart along the axial direction of the rotating shaft 21. The shielding plate 22 has a first end 221 and a second end 222 oppositely disposed. The first end 221 is provided with multiple sliding rods 26, which are slidably disposed on the slide rails 25 one-to-one. The second end 222 is provided with pin holes 223. When the shielding plates 22 between two adjacent car sections 10 need to be connected, the shielding plates 22 of the two adjacent car sections 10 can be connected by connecting rods 23 passing through the pin holes 223.

[0024] Specifically, along the length of the carriage 10, the carriage 10 has a first side wall 11 and a second side wall 12 arranged opposite to each other, and both the first side wall 11 and the second side wall 12 are provided with shielding components 20. A plurality of slide rails 25 are spaced apart on the rotation shaft 21 along the axial direction of the rotation shaft 21, and the slide rails 25 extend along the radial direction of the rotation shaft 21, so that the shielding plate 22 can move relative to the rotation shaft 21 in the radial direction of the rotation shaft 21.

[0025] in, Figure 2 Arrow A indicates the direction in which the shielding plate 22 rotates and unfolds, while the opposite direction indicates the direction in which the shielding plate 22 rotates and retracts. During actual transportation, after the ore is loaded into the transport car, the operator can control the rotation of the rotating shaft 21 to slide the shielding plate 22 along the slide rail 25, causing the shielding plate 22 to gradually unfold and cover the gap between adjacent car sections 10. Once the shielding plates 22 of both adjacent car sections 10 are fully unfolded, the connecting rod 23 is inserted into the pin hole 223 of the adjacent shielding plates 22 to connect them, thus forming a complete leak-proof structure.

[0026] Furthermore, when the transport car enters the curve, because the rotating shaft 21 is rotatably connected to the car body 10, and the shielding plate 22 is connected to the slide rail 25 via the sliding rod 26, the shielding plate 22 can automatically slide according to the changes in the posture of the car body 10 and the size of the gap. On the outside of the curve, the gap between the cars 10 will increase. At this time, the outer side of the shielding plate 22 can slide through the corresponding slide rail 25 and sliding rod 26 to extend the shielding length and fill the increased gap. On the inside of the curve, the gap between the two cars 10 will decrease. The shielding plate 22 can slide through the corresponding slide rail 25 and sliding rod 26 to adapt to the changes in the gap. That is, the shielding plate 22 can always maintain an optimal fit with the gap between the cars 10, effectively preventing ore from leaking out of the gap no matter how the transport car travels on the curve.

[0027] In summary, the leak-proof mining car provided by the present invention, through the setting of sliding rod 26 and slide rail 25, enables the shielding plate 22 to always maintain the best fit with the gap between the car body 10, which can adapt to the change of gap between the two car bodies 10 when the mining car is traveling on a curve, and effectively prevent ore leakage.

[0028] like Figure 4 As shown, in some embodiments, the slide rail 25 includes a guide sleeve 251, a hollow cavity 252 is provided inside the guide sleeve 251, a sliding rod 26 is movably inserted into the hollow cavity 252, an elastic element is provided between the sliding rod 26 and the guide sleeve 251, and the sliding rod 26 can be connected to the shielding plate 22 by welding, bolting or snap-fit ​​connection.

[0029] Specifically, the guide sleeve 251 limits the sliding direction of the sliding rod 26, effectively preventing the sliding rod 26 from wobbling or deviating during sliding, thus ensuring the stability and accuracy of the movement of the shielding plate 22. Furthermore, during the movement of the transport mine car, the sliding rod 26 will experience a certain degree of wobbling within the hollow cavity 252. At this time, the elastic element can absorb and disperse some of the external force through its own elastic deformation, reducing the impact force between the sliding rod 26 and the guide sleeve 251, thereby protecting the sliding rod 26 and the guide sleeve 251 from damage and extending their service life.

[0030] Furthermore, after the transport mine car completes its curve, the gaps between the car bodies 10 return to normal. The shielding plate 22 can automatically adjust its position under the action of the elastic element to ensure a tight fit with the gaps between the car bodies 10. This allows the shielding component 20 to quickly adapt to different working conditions, improving the operating efficiency of the transport mine car and the stability of the anti-leakage effect.

[0031] Furthermore, the elastic element can be set as a spring, which has good elasticity, toughness and fatigue strength.

[0032] Furthermore, the carriage 10 is equipped with a support rod 24, which extends along the length of the carriage 10 and is connected to the rotating shaft 21. The support rod 24 can increase the distance between the rotating shaft 21 and the inner wall of the carriage 10, so that the shielding plate 22 has a larger rotation angle during rotation, so as to connect with the shielding plate 22 on another carriage 10.

[0033] Optionally, the support rod 24 can be a telescopic rod. When the shielding assembly 20 is operating normally, the telescopic rod is in an extended state. At this time, the operator can adjust the length of the telescopic rod according to actual needs, thereby changing the distance between the rotating shaft 21 and the inner wall of the carriage 10. Since the change in the distance between the rotating shaft 21 and the inner wall of the carriage 10 directly affects the movement trajectory and spatial range of the shielding plate 22 during rotation, the maximum rotation angle of the shielding plate 22 can be flexibly adjusted. For example, when the distance between two adjacent carriages 10 is large, the telescopic rod can be extended to increase the distance between the rotating shaft 21 and the inner wall of the carriage 10, allowing the shielding plate 22 to rotate to a larger angle, thus connecting the two shielding plates 22; conversely, when the distance between two adjacent carriages 10 is small, the length of the telescopic rod can be appropriately shortened to reduce the distance between the rotating shaft 21 and the inner wall of the carriage 10, allowing the shielding plate 22 to rotate at a smaller angle, achieving precise shielding.

[0034] When the shielding assembly 20 is idle, i.e., when shielding is not required, the telescopic rod will be retracted. In this state, the telescopic rod will shorten its length to the minimum possible, thereby driving the rotating shaft 21 to move closer to the inner wall of the carriage 10. This allows the rotating shaft 21 and the shielding plate 22 to fit as close as possible to the inner wall of the carriage 10, reducing the space occupied by the shielding assembly 20 when idle.

[0035] In some embodiments, the shielding assembly 20 further includes a plurality of first actuators, each corresponding to a slide rail 25. The output end of the first actuator is connected to a sliding rod 26 or a shielding plate 22. The first actuator is used to drive the shielding plate 22 to slide relative to the rotation axis 21. When the gap between two adjacent carriages 10 changes, the first actuator can drive the shielding plate 22 to move, thereby achieving precise coverage of the gap.

[0036] The transport vehicle also includes a controller that can collect and analyze various operational data of the vehicle in real time, including speed, position, and direction of travel, especially information such as the status of curves the vehicle is about to or is currently passing. Based on this information, the controller can determine the changing trend of the gap between adjacent carriages 10 and send real-time adjustment commands to the first drive unit to adapt to the changes in the gap. This ensures that the shielding component 20 can always effectively cover the gap, guaranteeing smooth transport regardless of the vehicle's complex driving conditions.

[0037] Furthermore, the plurality of slide rails 25 includes at least a first slide rail 25 and a second slide rail 25, which are disposed opposite each other at both ends of the rotating shaft 21. When the transport mine car passes through a curve, the first slide rail 25 is located on the inner side of the transport mine car, and the second slide rail 25 is located on the outer side of the transport mine car. When the gap between two adjacent car sections 10 changes, the first actuators corresponding to the first and second slide rails 25 will operate synchronously to adjust the shielding plate 22.

[0038] Furthermore, the shielding assembly 20 also includes a second driver, which is mounted on the carriage 10. The output of the second driver is connected to the rotating shaft 21, and the second driver is used to drive the rotating shaft 21 to rotate relative to the carriage 10. The second driver can be electrically connected to a controller to enable the automatic unfolding or retraction of the shielding panel 22.

[0039] In some embodiments, the shielding assembly 20 further includes a magnetic attractor 27, which is disposed at the pin hole 223 of the shielding plate 22. When the shielding plates 22 between two adjacent carriages 10 come into contact, the magnetic attractors 27 on the two shielding plates 22 attract each other to achieve positioning, thereby facilitating the operator to insert the connecting rod 23 into the pin hole 223.

[0040] Furthermore, the shielding assembly 20 also includes a shock-absorbing pad 28. The shielding panel 22 has a first wall surface 224 and a second wall surface 225 disposed opposite to each other. The shock-absorbing pad 28 is disposed on the first wall surface 224, and the magnetic attractor 27 is disposed on the second wall surface 225. During the retraction of the shielding panel 22, the shielding panel 22 may collide with the side wall of the carriage 10. The shock-absorbing pad 28 can absorb and disperse the impact force, reducing the risk of damage to the shielding panel 22 due to strong impact.

[0041] Optionally, the thickness of the shock-absorbing pad 28 is set to 5-15mm, such as 5mm, 8mm, 10mm or 15mm.

[0042] Furthermore, the first wall surface 224 of the shielding plate 22 is provided with a wear-resistant coating, which can effectively resist the friction and scratching of hard objects such as ores and extend the service life of the first wall surface 224 of the shielding plate 22.

[0043] In some embodiments, the shielding assembly 20 further includes a vibration motor disposed on the shielding plate 22. The controller is electrically connected to the vibration motor and is used to regulate the vibration frequency of the vibration motor, thereby ensuring that the ore can pass through the shielding plate 22 continuously and smoothly, and preventing the ore from accumulating on the shielding plate 22.

[0044] Furthermore, the vibratory motor has at least two vibratory output shafts, the axial directions of which intersect in a straight line, and the vibration frequency of each output shaft is independently adjustable. When the mine car encounters uneven accumulation of ore on the shielding plate 22 during transportation, the intersecting vibratory output shafts can simultaneously apply vibration to the accumulated ore from different directions. For example, vibration in one direction can cause the ore to move horizontally, while vibration in another direction can cause it to bounce vertically. The combined effect of these two actions allows for faster and more thorough dispersion and discharge of the accumulated ore, significantly improving unloading efficiency.

[0045] Optionally, the vibration frequency of the vibration output shaft is set to 10-120Hz, such as 10Hz, 50Hz, or 120Hz. This range was determined through repeated testing and optimization. Within this frequency range, the vibratory motor can provide sufficient energy to effectively process various ores without causing excessive negative effects due to excessively high frequencies. For example, frequencies below 10Hz have an insignificant vibration effect and cannot effectively solve the problem of ore accumulation; while frequencies above 120Hz, although increasing vibration energy, lead to a sharp increase in energy consumption and accelerate the wear of internal parts of the vibratory motor, shortening the service life of the equipment.

[0046] During the operation of the leak-proof mining car provided in this embodiment of the invention, the operator can first rotate the slide rail 25 and the shielding plate 22 on the rotating shaft 21. At the same time, the rotating shaft 21 on the adjacent car 10 will also rotate the slide rail 25 and the shielding plate 22 on it. Simultaneously, the first driver will also drive the shielding plate 22 to slide relative to the slide rail 25 until the two shielding plates 22 contact each other. The connection can be achieved through the magnetic suction member 27 and the connecting rod 23. Furthermore, when the gap between two adjacent car 10 changes, each first driver will activate to move the shielding plate 22 to adapt to the change in gap. After the mining car has finished loading, the operator can remove the connecting rod 23 and adjust the rotating shaft 21 to rotate the shielding plate 22. At the same time, the first driver will also drive the shielding plate 22 to return to its original position until the shielding plate 22 is housed inside the car 10.
