Description

Technical Field

[0001] This utility model belongs to the field of ore processing technology, specifically, it relates to a tailings transport vehicle. Background Technology

[0002] During the mining process, a large amount of waste is generated after the ore is processed. This waste is usually called tailings. Tailings not only occupy a lot of land resources, but may also cause environmental pollution. A mine refers to an independent production and operation unit that extracts ore within a defined mining boundary. A mine mainly includes one or more mining workshops (also known as pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). During the mining process, transport vehicles are needed to transport the extracted ore within the mine. Existing transport vehicles have fully open tops for ease of use.

[0003] A document with publication number (CN112849172B) discloses an internal transport vehicle for mines, relating to the field of mining technology. This internal transport vehicle includes a truck bed, roller fixing rods, and rollers. The roller fixing rods are fixedly installed at the bottom of the truck bed, with both ends rotatably connected to the rollers. A protective device is fixed to the outer top of the truck bed, and a gravity drive mechanism is installed inside the protective device. The gravity drive mechanism is connected to the protective mechanism via a transmission mechanism, and the protective mechanism passes through a movable slot. When the transport vehicle passes through uneven terrain, the gravity drive mechanism, under the action of inertia, causes the protective mechanism to protect the ore inside the truck bed through the transmission mechanism, preventing the ore from spilling out. Furthermore, the swaying motion of the transport vehicle when passing through uneven terrain helps to contain the ore inside the truck bed, preventing it from injuring nearby workers and improving the safety of the transport vehicle.

[0004] The aforementioned device improves the opening defects of mining transport vehicles, but in actual use, when encountering pits and depressions, the mining transport vehicle is prone to tilting in the pits and depressions due to excessive internal load. Under the action of the full load, the center of gravity shifts, causing the mining transport vehicle to tip over, threatening the surrounding construction personnel and facilities, and causing the internal minerals to spill out, resulting in subsequent collection and processing problems.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problem of tilting in mining transport vehicles, the basic concept of the technical solution adopted by this utility model is as follows: A tailings transport vehicle includes a base, with symmetrically arranged movable wheels at the bottom of the base, the movable wheels being rotatably connected to the base, and a transport bucket being arranged on the base; an anti-tilting component is arranged between the base and the transport bucket, the anti-tilting component being used for self-adjustment of the tilt of the transport bucket, the anti-tilting component including a mounting seat, a limiting frame, a body, and a contact ring, the mounting seat being fixedly connected to the base, the limiting frame being arranged on the mounting seat, the body being movably arranged to the mounting seat, the body being fixedly connected to the bottom of the base, and the contact ring being arranged on the body.

[0007] In a preferred embodiment of this utility model, the corner of the transport bucket is provided with a screw rod, the screw rod is provided with a threaded groove, the screw rod is threadedly connected to the transport bucket through the threaded groove, and the corner of the transport bucket is provided with a hook, each hook being fixedly connected to the transport bucket.

[0008] In a preferred embodiment of this utility model, the interior of the mounting base is shaped like a ball socket, and the inner wall of the mounting base is surrounded by balls, each ball being connected to the mounting base through the ball socket structure.

[0009] In a preferred embodiment of this utility model, each ball is in close contact with the wall of the body, the limiting frame is fixedly connected to the mounting base, and a limiting ring is provided inside the limiting frame, with the limiting ring fixedly connected to the limiting frame.

[0010] In a preferred embodiment of this utility model, the contact ring is fixedly connected to the outer wall of the urn body, the contact ring and the limiting ring are arranged opposite to each other, and a dust cover is provided between the urn body and the mounting base.

[0011] In a preferred embodiment of this utility model, the interior space of the urn body is hollowed out, and a positioning module and a built-in power supply are respectively provided in the middle part of the urn body. The positioning module and the built-in power supply are both fixedly connected to the center position of the urn body.

[0012] In a preferred embodiment of this utility model, there is a gap between the positioning module, the built-in power supply and the inner wall of the urn, and the gap is filled with movable material.

[0013] In a preferred embodiment of this utility model, a signal receiving end is provided on the body of the urn, the signal receiving end is fixedly connected to the body of the urn, and the signal receiving end is electrically connected to the positioning module and the built-in power supply respectively.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This tailings transport vehicle, when affected by uneven terrain, causes one side of the device to tilt. The transport bucket is kept at its center of gravity by the movement of the hopper within the mounting base. This prevents the center of gravity of the transport bucket from shifting due to the tilt of the uneven area, which could cause it to tip over and spill minerals, threatening nearby construction personnel and equipment. It also avoids the space occupation and subsequent collection and cleanup problems caused by tipping over.

[0015] 2. This tailings transport vehicle, through the internal ball socket structure of the mounting base, provides a support point for the body at any center of gravity position, providing a sufficient foundation for the range of changes in the center of gravity of the device. Moreover, when the body moves during the change of center of gravity after the base is tilted, it abuts against the corresponding ball bearings. The ball bearings reduce the frictional force on the movement of the body by rotating, thereby reducing the friction generated during the adjustment of the center of gravity and improving the service life of the internal components.

[0016] 3. In this tailings transport vehicle, the rope connection between the hook and the base, as well as the limiting frame, limiting ring, and limiting body, are used to limit the range of tilt, so as to avoid exceeding the self-adjustment range, which would not only make the device not have the ability to adjust tilt, but also aggravate the tilt effect.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] Please see Figure 1-5 A tailings transport vehicle includes a base 1, with symmetrically arranged movable wheels 11 at the bottom of the base 1, the movable wheels 11 being rotatably connected to the base 1, and a transport bucket 2 being provided on the base 1. An anti-tilting component is disposed between the base 1 and the transport hopper 2. The anti-tilting component is used to self-adjust the tilt of the transport hopper 2. The anti-tilting component includes a mounting base 3, a limiting frame 32, a humping body 4 and a contact ring 41. The mounting base 3 is fixedly connected to the base 1. The limiting frame 32 is disposed on the mounting base 3. The humping body 4 is movably disposed on the mounting base 3. The humping body 4 is fixedly connected to the bottom of the base 1. The contact ring 41 is disposed on the humping body 4. During use, the transport bucket 2 is kept stable during loading and unloading to load and unload the minerals. Then, the transport bucket 2 is transported via the base 1 and the moving wheels 11. When the device is tilted to one side due to the influence of uneven terrain, the center of gravity of the transport bucket 2 is maintained by the movement of the body 4 within the mounting base 3. This prevents the center of gravity of the transport bucket 2 from shifting due to the tilt of the uneven area, which could cause it to tip over and spill minerals, posing a threat to the surrounding construction personnel and equipment. It also avoids the space occupation and subsequent collection and cleaning problems caused by tipping over.

[0022] The transport bucket 2 is provided with screws 12 at its corners, and threaded grooves 13 are provided on the screws 12. The screws 12 are threadedly connected to the transport bucket 2 through the threaded grooves 13. Hooks 21 are provided at the corners of the transport bucket 2, and each hook 21 is fixedly connected to the transport bucket 2. During the loading operation of minerals, first screw 12 at the bottom is screwed out to abut against the wall of base 1 to support the corners of transport bucket 2 and restrict the position of transport bucket 2, ensuring that transport bucket 2 is in a stable state during loading. After loading, screw 12 is loosened to the constricted part in the inner wall space of transport bucket 2, and a corresponding rope is tied between hook 21 and the corresponding base 1. However, the length of the rope must be sufficient to give transport bucket 2 a certain amount of room to move relative to base 1. During the unloading of minerals, the ropes are untied, and then one end of the transport bucket 2 is tilted to the other end to pour out the minerals at the top. Then, the remaining minerals at the bottom can be shoveled out with the help of tools.

[0023] The interior of the mounting base 3 is shaped like a ball socket, and the inner wall of the mounting base 3 is surrounded by balls 31, each ball 31 being connected to the mounting base 3 through the ball socket structure. Through the internal ball socket structure of the mounting base 3, the body 4 has a support point at any center of gravity position, providing a sufficient foundation for the range of center of gravity changes of the device. When the center of gravity changes after the base 1 is tilted, the body 4 moves and abuts against the corresponding ball bearing 31. The ball bearing 31 reduces the friction of the body 4 by rotating, reducing the friction generated during center of gravity adjustment and improving the service life of internal components.

[0024] Each ball bearing 31 is in close contact with the wall of the body 4. The limiting frame 32 is fixedly connected to the mounting base 3. A limiting ring 33 is provided inside the limiting frame 32. The limiting ring 33 is fixedly connected to the limiting frame 32. The contact ring 41 is fixedly connected to the outer wall of the body 4. The contact ring 41 and the limiting ring 33 are arranged opposite to each other. A dust cover is provided between the body 4 and the mounting base 3. The setting of the limiting frame 32 and the limiting ring 33 restricts the position of the contact ring 41 on the body 4 when the body 4 is tilted. The setting of the limiting ring 33 buffers the force generated by the impact, so as to avoid the impact force being too large and the change of the position of the mineral in the transport bucket 2 being too large, causing the center of gravity to shift seriously, and tilting after resetting, which will affect the use of the device. Because the weight of the transport bucket 2 increases after being filled with minerals, the weight at the top becomes too large. Therefore, the rope connection between the hook 21 and the base 1, as well as the limiting frame 32, the limiting ring 33 and the limiting body 4, are used to limit the tilt range to prevent it from exceeding the self-adjustment range, which would not only make the device unable to adjust the tilt but also aggravate the tilt effect.

[0025] The interior of the body 4 is hollowed out. A positioning module 43 and a built-in power supply 44 are respectively set in the middle part of the body 4. The positioning module 43 and the built-in power supply 44 are fixedly connected to the center of the body 4. There are gaps between the positioning module 43, the built-in power supply 44 and the inner wall of the body 4. The gaps are filled with movable material. A signal receiving end 42 is set on the body 4. The signal receiving end 42 is fixedly connected to the body 4 and is electrically connected to the positioning module 43 and the built-in power supply 44 respectively. The weight of the body 4 is ensured by the positioning module 43 and the built-in power supply 44, and the movable material filling the gap between the positioning module 43, the built-in power supply 44 and the body 4, while providing the body 4 with the ability to adjust the center of gravity due to the movement of the internal material. Furthermore, the signal receiver 42 is used to send and receive signals, and the positioning module 43 is used to transmit the location of the device in real time, so that in special circumstances, the personnel can quickly find the location of the device. The built-in power supply 44 supplies power to the signal receiver 42 and the positioning module 43. Special circumstances include production safety, personnel safety, and emergencies. It is worth noting that the positioning module 43 includes the following steps: receiving location information sent by the underground miners through a signal transmitting device; converting the location information into a power line carrier communication signal and transmitting it into the power cable underground; receiving the power line carrier communication signal from the power cable and determining the location of the underground miners based on the power line carrier communication signal. The above invention reduces the cost required for underground miners to perform positioning and improves the versatility of existing equipment. The positioning module 43 has been fully disclosed in the prior art CN103696808B Underground Mine Personnel Positioning System and Method, and will not be described again here.

[0026] Working Principle: During operation, the transport bucket 2 is kept stable during loading and unloading. Minerals are loaded and unloaded, and then transported via the base 1 and casters 11. When the device tilts to one side due to uneven terrain, the transport bucket 2 maintains its center of gravity due to the movement of the body 4 within the mounting base 3. This prevents the center of gravity from shifting due to the tilt of the uneven area, which could cause the bucket to tip over and spill minerals, posing a threat to nearby workers and equipment. It also avoids the space occupation and subsequent collection and cleanup problems caused by tipping. During the filling operation, the bottom screw 12 is first screwed out to abut against the wall of the base 1, supporting the corners of the transport bucket 2 and restricting its position. To ensure the transport hopper 2 remains stable during loading, after loading, loosen the screw 12 towards the inner wall space of the transport hopper 2, and tie the corresponding rope between the hook 21 and the corresponding base 1. The rope length must be sufficient to allow the transport hopper 2 some room to move relative to the base 1. To unload the minerals, untie the ropes and tilt one end of the transport hopper 2 to the other to directly pour out the top minerals. Then, use a tool to shovel out any remaining minerals at the bottom. The internal ball-and-socket structure of the mounting base 3 provides support points for the urn body 4 at any center of gravity position, providing a sufficient foundation for the range of changes in the device's center of gravity. Furthermore, the urn body 4 moves as the center of gravity changes after the base 1 is tilted, interacting with the corresponding ball bearings 3. The contact ball 31, through rotation, reduces friction on the moving body 4, decreasing friction during center-of-gravity adjustment and improving the service life of internal components. The limiting frame 32 and limiting ring 33 restrict the position of the contact ring 41 on the body 4 during tilting. The limiting ring 33 also buffers the impact force, preventing excessive impact that could cause significant changes in the mineral position within the transport hopper 2, leading to a severe shift in the center of gravity and tilting after resetting, thus affecting the device's usability. Because the weight of the transport hopper 2 increases after filling with minerals, resulting in excessive weight at the top, the rope connection between the hook 21 and base 1, as well as the limiting frame 32, limiting ring 33, and the body 4's positioning, are used to limit the tilt range. To prevent the device from exceeding its self-adjustment range, which would not only render it incapable of tilt adjustment but also exacerbate the tilting effect, the weight of the body 4 is ensured by the positioning module 43 and the built-in power supply 44, with movable material filling the gap between the positioning module 43, the built-in power supply 44 and the body 4. This provides the body 4 with the ability to adjust its center of gravity due to the movement of internal materials. The signal receiver 42 is used to transmit and receive signals, and the positioning module 43 is used to transmit the device's position in real time. This allows personnel to quickly locate the device in special circumstances. The built-in power supply 44 provides power to the signal receiver 42 and the positioning module 43. Special circumstances include production safety, personnel safety, and emergencies.
