Description

Technical Field

[0001] This invention belongs to the field of underground mining vehicle manufacturing technology, specifically an underground mining vehicle with independent suspension shock absorption. Background Technology

[0002] Underground transport vehicles are key equipment used for material transportation in mining operations, primarily responsible for transporting ore, waste rock, equipment, and personnel underground. Depending on the type of mine (e.g., coal mine, metal mine), mining method, and working environment, the types and designs of underground transport vehicles vary considerably. To improve safety underground, short-distance transport vehicles are often manually operated. However, current underground transport vehicles have several problems: 1. The underground surface environment is complex, requiring wheel cushioning to improve vehicle stability. However, current wheel cushioning methods often involve two wheels sharing a single shock absorber, resulting in poor shock absorption. 2. When transporting ore via hoppers, bucket covers are needed to prevent dust generation. However, the excessive weight of the bucket covers increases the overall weight of the vehicle, leading to increased labor intensity. 3. Hoppers are typically limited by simple pins, which can easily detach during vehicle movement, causing hopper instability. Therefore, it is necessary to design an underground transport vehicle with independent suspension and shock absorption. Summary of the Invention

[0003] The purpose of this invention is to provide a mine transport vehicle with independent suspension and shock absorption to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, this invention provides a technical solution for an underground mining transport vehicle employing independent suspension and shock absorption: A mining transport vehicle with independent suspension and shock absorption includes a base plate. A hopper is hinged to the upper end of the base plate, and a dust-prevention mechanism is provided on the hopper. A locking mechanism is provided on the base plate. Multiple evenly distributed support frames are fixedly connected to the lower end of the base plate. Two symmetrically distributed hinge columns are hinged inside each support frame. A wheel frame is hinged to the outer side of the two hinge columns. A wheel is installed inside the wheel frame through a bearing. A support bar is fixedly connected to the upper end of the wheel frame. A guide rod pin is fixedly connected to the upper end of the support bar. Four evenly distributed fixing plates are welded to the upper end of the base plate. A hydraulic damping rod is fixedly connected to the upper end of the fixing plates. A spring is provided on the outer side of the guide rod pin.

[0005] Preferably, one end of the spring is fixedly connected to the support bar, and the other end of the spring is fixedly connected to the fixing plate. The spring can support the support bar through its elastic force.

[0006] Preferably, the output rod of the hydraulic damping rod is fixedly connected to the support bar, and the guide rod pin is slidably connected to the fixing plate, so that the guide rod pin can guide the movement of the support bar.

[0007] Preferably, the dust-proof mechanism includes a storage box, which is fixedly connected to the outside of the hopper. A winding roller is installed inside the storage box via bearings. Nylon cloth is wound around the outside of the winding roller. A protective cover is fixedly connected to the front of the storage box. A spring is installed inside the protective cover. A connecting strip is fixedly connected to the end of the nylon cloth away from the storage box. Two symmetrically distributed limiting seats are fixedly connected to the outside of the hopper. The storage box, winding roller, and protective cover are made of plastic, which can effectively reduce weight.

[0008] Preferably, one end of the spring is fixedly connected to the connecting shaft of the take-up roller, and the other end of the spring is fixedly connected to the rod on the outside of the storage box. The limiting seat is slidably connected to the connecting strip, and the nylon cloth is in contact with the hopper. The spring can drive the take-up roller to rotate by power.

[0009] Preferably, the locking mechanism includes locking ears. Two symmetrically distributed locking ears are fixedly connected to the outer side of the hopper. Two symmetrically distributed fixed seats are fixedly connected to the upper end of the base plate. A locking pin is slidably connected inside the fixed seat. A pull rod is fixedly connected to the outer side of the locking pin. A hinge bar is hinged to the outer side of the pull rod. A pedal is hinged between the two hinge bars. Two symmetrically distributed guide rods are fixedly connected to the upper end of the base plate. A second spring is provided on the outer side of the pull rod. When the pedal is stepped on, the pedal causes the hinge bar to deflect. During the deflection, the hinge bar causes the pull rod to move. During the movement, the pull rod can cause the locking pin to move and compress the second spring. When the locking pin disengages from the locking ears, the hopper can be released from its limit. Then, the hopper can be flipped over to complete the unloading.

[0010] Preferably, the guide rod is slidably connected to the pedal, the pull rod is slidably connected to the fixed seat, and the locking pin is slidably connected to the locking lug. The locking pin can limit the hopper through the locking lug.

[0011] Preferably, one end of the second spring is fixedly connected to the fixed base, and the other end of the second spring is fixedly connected to the locking post. The second spring can support the locking post through its elastic force.

[0012] The beneficial effects of this invention are: First, by adding structures such as hinge columns, hydraulic damping rods and fixed plates to the base plate, the wheels can be supported individually by the hinge columns, wheel frames and support frames. When a single wheel of the vehicle is impacted, the hydraulic damping rod can buffer the impact on that single wheel, thereby effectively improving the stability of the vehicle. Secondly, by adding structures such as nylon cloth, storage box and limiting seat to the hopper, the hopper can be covered by the nylon cloth during use, and can be stored in the storage box. Thus, the nylon cloth can replace the hopper cover, which can effectively reduce the overall weight of the hopper. Secondly, by adding a fixed seat, locking pin, and pedal to the base plate, the locking pin can be driven by the elastic force of spring two to slide into the locking ear to position the hopper, thereby making the hopper more stable in its position. When it is necessary to release the limit, simply step on the pedal to release the limit, making unloading more convenient. Attached Figure Description

[0016] like Figure 1-10 As shown, the specific implementation adopts the following technical solution: Example

[0017] A mine transport vehicle with independent suspension and shock absorption includes a base plate 1. A hopper 2 is hinged to the upper end of the base plate 1. A dust prevention mechanism 3 is installed on the hopper 2. A locking mechanism 4 is installed on the base plate 1. Multiple evenly distributed support frames 5 are fixedly connected to the lower end of the base plate 1. Two symmetrically distributed hinged columns 6 are hinged inside each support frame 5. A wheel frame 7 is hinged to the outer side of the two hinged columns 6. A wheel 8 is installed inside the wheel frame 7 through bearings. A support bar 9 is fixedly connected to the upper end of the wheel frame 7. A guide rod nail 11 is fixedly connected to the upper end of the support bar 9. Four evenly distributed fixing plates 10 are welded to the upper end of the base plate 1. A hydraulic damping rod 12 is fixedly connected to the upper end of the fixing plate 10. A spring 13 is provided on the outer side of the guide rod nail 11. One end of the spring 13 is fixedly connected to the support bar 9, and the other end of the spring 13 is fixedly connected to the fixing plate 10. The spring 13 can support the support bar 9 with its elastic force. The output rod of the hydraulic damping rod 12 is fixedly connected to the support bar 9. The guide rod nail 11 is slidably connected to the fixing plate 10. The guide rod nail 11 can guide the movement of the support bar 9.

[0018] The dust-proof mechanism 3 includes a storage box 31, which is fixedly connected to the outside of the hopper 2. A winding roller 32 is installed inside the storage box 31 via bearings. Nylon cloth 33 is wound around the outside of the winding roller 32. A protective cover 34 is fixedly connected to the front of the storage box 31. A spring 35 is provided inside the protective cover 34. A connecting strip 36 is fixedly connected to the end of the nylon cloth 33 away from the storage box 31. Two symmetrically distributed limiting seats 37 are fixedly connected to the outside of the hopper 2. The storage box 31, winding roller 32, and protective cover 34 are made of plastic, which can effectively reduce weight. One end of the spring 35 is fixedly connected to the connecting shaft of the winding roller 32, and the other end of the spring 35 is fixedly connected to a rod on the outside of the storage box 31. The limiting seat 37 is slidably connected to the connecting strip 36. The nylon cloth 33 is in contact with the hopper 2. The spring 35 can drive the winding roller 32 to rotate through power.

[0019] The locking mechanism 4 includes locking ears 41. Two symmetrically distributed locking ears 41 are fixedly connected to the outer side of the hopper 2. Two symmetrically distributed fixed seats 42 are fixedly connected to the upper end of the base plate 1. A locking pin 43 is slidably connected inside the fixed seat 42. A pull rod 44 is fixedly connected to the outer side of the locking pin 43. A hinge bar 45 is hinged to the outer side of the pull rod 44. A pedal 46 is hinged between the two hinge bars 45. Two symmetrically distributed guide rods 47 are fixedly connected to the upper end of the base plate 1. A spring 48 is provided on the outer side of the pull rod 44. When the pedal 46 is stepped on, the pedal 46 drives the hinge bar 45 to deflect. During the deflection process, the hinge bar 45 drives the pull rod. The lever 44 moves, and during the movement, the locking pin 43 moves and compresses the second spring 48. When the locking pin 43 disengages from the locking ear 41, the limiting of the hopper 2 can be released, and then the hopper 2 can be flipped to complete the unloading. The guide rod 47 is slidably connected to the pedal 46, the lever 44 is slidably connected to the fixed seat 42, and the locking pin 43 is slidably connected to the locking ear 41. The locking pin 43 can limit the hopper 2 through the locking ear 41. One end of the second spring 48 is fixedly connected to the fixed seat 42, and the other end of the second spring 48 is fixedly connected to the locking pin 43. The second spring 48 can support the locking pin 43 through its elasticity.

[0020] The usage state of this invention is as follows: When in use, after the hopper 2 is filled, the connecting strip 36 is pulled. The connecting strip 36 drives the nylon cloth 33 to move. During the movement of the nylon cloth 33, the winding roller 32 can rotate. During the rotation of the winding roller 32, the spring 35 can store energy. When the connecting strip 36 moves above the limiting seat 37, the connecting strip 36 is sleeved on the outside of the limiting seat 37, which can shield the hopper 2, thereby avoiding dust and reducing the overall weight of the hopper 2. Pushing the hopper 2, the vehicle moves through the wheels 8. During the movement of the vehicle, when a single wheel 8 comes into contact with a foreign object, the wheel 8 moves upward. As the wheel plate 8 moves upward, it can push the output rod of the hydraulic damping rod 12 into the interior of the hydraulic damping rod 12. The damping force moves the support bar 9, and the support bar 9 compresses the spring 13, which can buffer the single wheel 8, thereby improving the stability of the vehicle movement. When unloading is required, the winding roller 32 is rotated by the elastic force of the spring 35. During the rotation, the winding roller 32 can retract the nylon cloth 33. After the nylon cloth 33 is retracted, the foot pedal 46 is stepped on. The pedal 46 drives the hinge bar 45 to deflect. During the deflection, the hinge bar 45 drives the pull rod 44 to move. During the movement, the pull rod 44 can drive the locking pin 43 to move and compress the spring 48. When the locking pin 43 disengages from the locking ear 41, the limit on the hopper 2 can be released. Then, the hopper 2 can be flipped over to complete the unloading.
