Description

Technical Field

[0001] The present invention belongs to the technical field of ore car unloading, and particularly relates to an auxiliary unloading device for a side-dumping ore car. Background Art

[0002] An ore car is a narrow-gauge railway handling vehicle for transporting bulk materials such as coal, ore, and waste rock in a mine, and generally needs to be towed by a locomotive or a winch. Ore cars are classified into five categories according to different structures and unloading methods: fixed ore cars (material cars, flat cars), dump ore cars, single-side curved rail side-dumping ore cars, bottom (side)-dumping ore cars, and shuttle ore cars.

[0003] After the existing ore cars are loaded with bulk ore materials such as coal, ore, and waste rock, on the one hand, the ore materials are mixed with water during the ore material mining process, and water is also sprinkled to prevent the spread of ore material dust during loading, resulting in the adhesion of ore materials in the ore car. On the other hand, the ore materials in the ore car are affected by the bumping vibration force during transportation, and the bottom materials are squeezed against each other, causing the ore materials to be compacted at the bottom. Therefore, when the ore car is unloading, the unloading is not clean, or the unloading cannot be carried out smoothly. Since the unloading process is that the guide wheels move along the curved rail to make the hopper turn over and the unloading port open, and the guide wheels move smoothly along the smooth curved rail, the hopper also turns over stably and gently. It is very difficult for the adhered ore materials to automatically slide down from the unloading port. Therefore, for ore cars with adhered ore materials, it is necessary to clean them manually when the ore car stops in order to unload the ore materials in the hopper cleanly. Summary of the Invention

[0004] The purpose of the present invention is to propose an auxiliary unloading device for a side-dumping ore car in order to solve the problems of unsmooth, incomplete, and unclean unloading of a single-side curved rail side-dumping ore car in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solution: An auxiliary discharging device for a side-dumping ore truck.

The guiding block is slidably arranged in the guiding groove.

[0008] As a further description of the above technical solution: A rotating sliding shaft is provided on the vertical side surface of the stop rod.

[0009] As a further description of the above technical solution: a telescopic component and a rotating component are provided in the fixed arm and the telescopic arm. The telescopic component enables the telescopic arm to slide along the fixed arm, and the rotating component is used to drive the material pushing member to rotate around the telescopic arm. The telescopic component includes a pull rod, a third spring, a steel wire rope, a reel, a first positioning block, and a second positioning block. The first positioning block is fixedly arranged in the telescopic arm, and the second positioning block is fixedly arranged in the fixed arm. One end of the pull rod is rotatably arranged in the first positioning block, and the other end of the pull rod slidably penetrates through the second positioning block.

The reel is rotatably arranged at one end of the fixed arm away from the telescopic arm. One end of the steel wire rope is wound on the reel, and the other end is connected to the pull rod.

[0010] As a further description of the above technical solution: the rotating component includes a universal joint, a first bevel gear, a second bevel gear, a connecting shaft, and a torsion spring. The connecting shaft is rotatably arranged at one end of the telescopic arm away from the fixed arm. The connecting shaft and the pull rod are connected through a universal joint.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0014] (1) The auxiliary unloading device of the present application can, under the action of the material pushing member, smoothly unload the ore materials adhered to the side-dumping ore truck. The auxiliary unloading device and the side-dumping ore truck move simultaneously, enabling the material pushing member to smoothly insert into the ore materials in the hopper without interfering with the hopper, and when the material pushing member is pulled out of the hopper, it stirs the adhered ore materials, causing the ore materials to be discharged from the hopper opening.

[0015] (2) The movement of the follow-up component along the track direction and the sliding of the follow-up rod along the mounting block cause the fixed arm, the telescopic arm 23, and the material pushing member to move simultaneously with the hopper. After moving to one end far from the semi-unloading section, the follow-up rod disengages from the unloading wheel and no longer receives the action of the unloading wheel, causing the fixed arm, the telescopic arm 23, and the material pushing member to return to the initial state under the action of the third spring, so as to assist in unloading the next side-dumping ore truck.

[0016] (3) The present application does not require an additional power source and can complete the unloading assistance for multiple side-dumping ore trucks connected in series. It can assist in unloading each side-dumping ore truck passing through the ore unloading curved rail to achieve complete unloading of the ore materials in the hopper. When the unloading ore trucks with different moving speeds pass through the complete unloading section, the material pushing member can stably and uniformly move with the side-dumping ore truck and assist in unloading. In extreme cases such as when the ore materials are tightly adhered, the device can also perform a secondary auxiliary unloading process to further stir the ore materials in the hopper, causing the ore materials to be discharged from the hopper.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1-8 , the present invention provides a technical solution for an auxiliary discharging device of a side-dumping ore truck.

[0028] The side-dumping ore truck 1 includes a frame 2, a discharging wheel 3, and a hopper 4. The side-dumping ore truck 1 moves along the track. A discharging area is provided on one side of the track, and an ore-discharging curved rail 5 is provided on the other side of the track. The ore-discharging curved rail 5 corresponds to the discharging area. The ore-discharging curved rail 5 is composed of a semi-discharging section 6, a full-discharging section 7, and a closing section 8. The semi-discharging section 6, the full-discharging section 7, and the closing section 8 form a trapezoidal track. Among them, the full-discharging section 7 is horizontally arranged, the semi-discharging section 6 and the closing section 8 are inclined, and the semi-discharging section 6 and the closing section 8 are symmetric about the full-discharging section 7. When the side-dumping ore truck 1 moves to the discharging area, the discharging wheel 3 causes the hopper 4 to discharge under the action of the ore-discharging curved rail 5. When the side-dumping ore truck 1 moves to the position where the discharging wheel 3 corresponds to the semi-discharging section 6 and slides along it, the discharging port of the hopper 4 gradually opens and discharges. When the discharging wheel 3 moves along the semi-discharging section 6 of the ore-discharging curved rail 5 to correspond to the full-discharging section 7, the discharging port of the hopper 4 fully opens for discharging. When the side-dumping ore truck 1 moves to the position where the discharging wheel 3 corresponds to the closing section, the discharging is completed, and the discharging port of the hopper 4 gradually closes.

[0029] When the hopper 4 is in the complete unloading section 7, the auxiliary unloading device performs a complete unloading operation. The auxiliary unloading device includes a traveling assembly 13 that reciprocates along the complete unloading section 7. A reciprocating mounting block 9 is provided on the unloading curved track 5. The traveling assembly 13 is provided on the mounting block 9. A guide rod 10 is provided between the semi-unloading section 6 and the closing section 8. The guide rod 10 is parallel to the complete unloading section 7 and is located directly below the complete unloading section 7. The mounting block 9 is slidably mounted on the guide rod 10. A first spring 11 and a second spring 12 are mounted on the guide rod 10. The first spring 11 is located between the semi-unloading section 6 and the mounting block 9. One end of the first spring 11 is fixedly connected to the semi-unloading section 6, and the other end is fixedly connected to the mounting block 9. The second spring 12 is located between the mounting block 9 and the closing section 8. One end of the second spring 12 is fixedly connected to the mounting block 9, and the other end is fixedly connected to the closing section 8.

[0030] The accompanying assembly 13 includes a transverse guide rail 14 and a accompanying rod 16. The transverse guide rail 14 is arranged between the complete unloading section 7 and the mounting block 9. A guide groove 15 is provided on the transverse guide rail 14. The accompanying rod 16 is composed of a stop rod 17, a connecting rod 19, and a sliding rod 20. The stop rod 17 is located above the complete unloading section 7. A rotating slide shaft 18 is provided on the vertical side of the stop rod 17. The stop rod 17 corresponds to the unloading wheel 3. A limit block is provided on the mounting block 9. The limit block is located between the transverse guide rail 14 and the mounting block 9. The sliding rod 20 is slidably set in the limit block. The sliding direction of the sliding rod 20 is perpendicular to the extension direction of the track. The connecting rod 19 is vertically arranged. One end of the connecting rod 19 is connected to the stop rod 17, and the other end is connected to the sliding rod 20. The end of the sliding rod 20 away from the connecting rod 19 is provided with a guide block 21, and the guide block 21 is slidably set in the guide groove 15.

[0031] like Figure 1 As shown, in the initial state, the accompanying assembly 13 is located at the transition position between the semi-discharging section 6 and the complete discharging section 7. At this time, the first spring 11 and the second spring 12 are in a natural state. When the discharging wheel 3 moves to contact the stop rod 17, as the discharging wheel 3 continues to move along the complete discharging section 7, the discharging wheel 3 drives the stop rod 17 to move together, and the accompanying rod 16 drives the mounting block 9 to move, wherein the first spring 11 is stretched and the second spring 12 is compressed. While the accompanying rod 16 moves under the action of the discharging wheel 3, the sliding rod 20 of the accompanying rod 16 slides along the limit block on the mounting block 9 under the action of the guide groove 15 and the guide block 21, so that the accompanying rod 16 also moves away from the hopper 4. When the accompanying assembly 13 moves along the complete discharging section 7 to the transition position between the complete discharging section 7 and the closing section 8, as shown in FIG. Figure 2 As shown, the blocking rod 17 is then disconnected from the discharge wheel 3 , and under the action of the first spring 11 and the second spring 12 , the accompanying assembly 13 and the concealed block return to their initial states.

[0032] The auxiliary discharging device further includes a fixed arm 22, a telescopic arm 23, and a material pushing member 24. The fixed arm 22 is connected to the mounting block 9 through a connecting column. One end of the connecting column is fixedly connected to the lower surface of the mounting block 9, and the other end is fixedly connected to the fixed arm 22. The telescopic arm 23 is slidably sleeved on one end of the fixed arm 22 away from the mounting block 9. The material pushing member 24 is rotatably arranged at one end of the telescopic arm 23 away from the fixed arm 22. The material pushing member 24 is located directly above the track and is used to push the ore in the hopper 4. The material pushing member 24 is a steel fork or a steel shovel.

[0033] Both the fixed arm 22 and the telescopic arm 23 are tubular structures. The fixed arm 22 consists of a first inclined portion and a vertical portion. The telescopic arm 23 consists of a second inclined portion and a horizontal portion. One end of the vertical portion of the fixed arm 22 is fixedly connected to the connecting column. The second inclined portion of the telescopic arm 23 is slidably sleeved on the first inclined portion of the fixed portion. The material pushing member 24 is rotatably arranged on the horizontal portion of the telescopic arm 23.

[0034] A telescopic component 25 and a rotating component 42 are arranged inside the fixed arm 22 and the telescopic arm 23. The telescopic component 25 enables the telescopic arm 23 to slide along the fixed arm 22. The rotating component 42 is used to drive the material pushing member 24 to rotate around the telescopic arm 23. The telescopic component 25 includes a pull rod 26, a third spring 27, a steel wire rope 28, a reel 29, a first positioning block 30, and a second positioning block 31. The first positioning block 30 is fixedly arranged inside the second inclined portion of the telescopic arm 23. The second positioning block 31 is fixedly arranged inside the first inclined portion of the fixed arm 22. One end of the pull rod 26 is rotatably arranged inside the first positioning block 30. The other end of the pull rod 26 slidably penetrates through the second positioning block 31. The third spring 27 is sleeved on the pull rod 26 and is located between the first positioning block 30 and the second positioning block 31. The reel 29 is rotatably arranged at one end of the fixed arm 22 away from the telescopic arm 23. One end of the steel wire rope 28 is wound around the reel 29, and the other end is connected to the pull rod 26.

[0035] The rotating assembly 42 includes a universal joint 43, a first bevel gear 44, a second bevel gear 45, a connecting shaft 46, and a torsion spring 47. The connecting shaft 46 is rotatably arranged at one end of the telescopic arm 23 away from the fixed arm 22. The connecting shaft 46 is arranged inside the horizontal part of the telescopic arm 23. The connecting shaft 46 and the pull rod 26 are connected by the universal joint 43. A rotating shaft is rotatably arranged at one end of the telescopic arm 23 away from the fixed arm 22. The rotating shaft is fixed to the material deflecting member 24. The first bevel gear 44 is coaxially fixed on the rotating shaft. The second bevel gear 45 is coaxially fixed on the connecting shaft 46. The first bevel gear 44 and the second bevel gear 45 mesh with each other. The torsion spring 47 is sleeved on the rotating shaft. A track groove 33 is formed on the side wall of the pull rod 26. The track groove 33 is composed of a vertical groove 34, a spiral groove 35, and an arc groove 36. The vertical groove 34, the spiral groove 35, and the arc groove 36 are connected end to end in sequence. At the connection of the vertical groove 34 and the spiral groove 35, the depth of the spiral groove 35 is greater. An elastic guiding head 32 is arranged on the second positioning block 31. The elastic guiding head 32 is slidably arranged in the track groove 33.

[0036] A rack 37 is arranged between the semi-unloading section 6 and the closing section 8. The rack 37 is arranged along the track direction. The part of the rack 37 close to the semi-unloading section 6 has teeth, and the part of the rack 37 close to the closing section 8 has no teeth. A gear 38 is coaxially arranged on the reel 29. The gear 38 corresponds to the rack 37. A ratchet and pawl assembly is arranged between the reel 29 and the gear 38. The ratchet and pawl assembly includes a collar 40 and a pawl 41. An internal engaging tooth 39 is formed on the end face of the gear 38. The collar 40 is coaxially fixed on the reel 29. The pawl 41 is arranged on the periphery of the collar 40. The pawl 41 corresponds to the engaging tooth.

[0037] Working principle: After the side-dumping ore truck 1 is loaded with ore, it moves along the track to the unloading area for unloading under the traction of a tractor. When the unloading wheel 3 of the side-dumping ore truck 1 corresponds to the semi-unloading section 6 of the unloading curved rail 5 and slides along it, the unloading opening of the hopper 4 is gradually opened for unloading. When the unloading wheel 3 moves along the semi-unloading section 6 of the unloading curved rail 5 to correspond to the full-unloading section 7, the unloading opening of the hopper 4 is fully opened for unloading. At this time, the material deflecting member 24 is completely located above the hopper 4. Subsequently, the hopper 4 moves along the full-unloading section 7 in a fully opened state. At this time, the unloading wheel 3 drives the accompanying assembly 13 and the mounting block 9 to move, and also drives the fixed arm 22, the telescopic arm 23, and the material deflecting member 24 to move simultaneously. When moving, the gear 38 moves along the rack 37. At this time, the internal engaging tooth 39 is engaged with the pawl 41. The gear 38 drives the reel 29 to rotate. The steel wire rope 28 winds around the reel 29. During the process of winding the steel wire rope 28, the pull rod 26 is pulled into the fixed arm 22, causing the telescopic arm 23 to move towards the fixed arm 22. The telescopic arm 23 drives the material deflecting member 24 to insert into the hopper 4. During the above process, the third spring 27 is compressed. The elastic guiding head 32 moves from one end of the vertical groove 34 to the other end and enters the spiral groove 35.

[0038] When the gear 38 moves along the rack 37 to the toothless part on the rack 37, the rack 37 does not mesh with the gear 38. Under the action of the third spring 27, the telescopic arm 23 moves away from the fixed arm 22. Since the elastic guide head 32 moves along the spiral groove 35, the pull rod 26 rotates. While the pull rod 26 rotates, the connecting shaft 46 is driven to rotate through the universal joint 43. Under the transmission action of the first bevel gear 44 and the second bevel gear 45, the rotating shaft drives the material-dipping member 24 to rotate, thereby digging the ore in the hopper 4 during the unloading process, so that the ore bonded in the hopper 4 can flow out smoothly. When the telescopic arm 23 returns to its initial state, the elastic guide head 32 enters the arc groove 36. At this time, under the action of the torsion spring 47, the rotating shaft rotates to drive the connecting shaft 46, the universal joint 43 and the pull rod 26 to rotate, so that the material-dipping member 24 and the telescopic arm 23 return to their initial state, and the elastic guide head 32 enters the vertical groove 34.

[0039] The above unloading process can complete the auxiliary unloading of relatively loose mineral materials and mineral materials that are not tightly bonded. When encountering extreme situations, such as when the mineral materials are tightly bonded, after the material-dispensing member 24 is inserted into the hopper 4, under the action of the third spring 27, the material-dispensing member 24 cannot rotate to realize material dispensing. At this time, the unloading wheel 3 and the hopper 4 will drive the accompanying assembly 13, the material-dispensing member 24, the fixed arm 22, and the telescopic arm 23 to move, but the material-dispensing member 24 cannot rotate, and the telescopic arm 23 cannot slide along the fixed arm 22. Therefore, after moving to the transition position between the complete unloading section 7 and the closing section 8 in this state, the unloading wheel 3 no longer generates a driving force on the accompanying rod 16, so the material-dispensing member 24, the telescopic arm 23 and the fixed arm 22 are all There is a tendency to slide away from the closing section 8, and the hopper 4 continues to slide along the closing section 8, and the hopper 4 is also slowly closed. Therefore, there is a relative movement between the material-dispensing member 24 and the hopper 4. The relative movement in this state is also a material-dispensing state. Further dispensing of the tightly bonded mineral materials will result in a secondary material-dispensing process. Through the secondary material-dispensing action, it can be further ensured that the mineral materials in the hopper 4 are cleaned up. After the secondary material-dispensing process is completed, under the action of the first spring 11, the second spring 12, and the third spring 27, the auxiliary unloading device returns to its initial state and performs auxiliary unloading on the next hopper 4.

[0040] When the installation block 9 is Figure 2 Status restored to Figure 1 During the state, when the gear 38 is engaged with the rack 37 , the pawl 41 is not engaged with the inner teeth 39 , so the reel 29 does not rotate.

[0041] The above description is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and all of these should be covered by the protection scope of the present invention.
