Description

Technical Field

[0001] The invention relates to the technical field of subway inclined shaft slag discharge, in particular to a subway inclined shaft continuous slag discharge device. Background Art

[0002] Inclined shafts are inclined tunnels that are directly connected to the ground, and their functions are the same as those of vertical shafts and horizontal tunnels. Inclined shafts that are not directly connected to the ground are called blind inclined shafts or blind inclined shafts, and their functions are the same as those of blind vertical shafts. There are two methods for constructing subway stations: underground excavation and open excavation, while there are three methods for constructing subway tunnels: open excavation, underground excavation, and shield tunneling. Whether it is underground excavation of stations or underground excavation or shield tunneling of tunnels, a vertical shaft or inclined shaft must be excavated first to facilitate the up and down transportation of construction materials. In addition, subway station entrances and exits must be built in the later stages of the main construction of the subway station, generally in the form of straight stairs and escalators. When the construction of subway stations and tunnels enters the equipment installation stage, civil engineering often only completes the entrances and exits, while the vertical shafts and inclined shafts are occupied by civil construction operations.

[0003] In existing subway inclined shafts, such as those described in Chinese patent application CN113236350A, when the steel strands pull on a movable plate to move a railcar up or down the track, the two ends of the movable plate squeeze two brake levers, causing them to open and stretch the tension springs. This prevents the second baffle from contacting the first baffle during the railcar's movement. If the traction winch fails, causing the steel strands to uncontrollably release and fail to pull the railcar, or if the strands break, the movable plate cannot open the two brake levers. Instead, the tension of the tension springs causes the two brake levers to retract, blocking the second baffle with the first baffle. This stops the railcar and achieves a braking effect, solving the problem of heavy material transportation in the later stages of subway construction.

[0004] However, there are still the following problems: inclined shaft transportation is mostly single-track or double-track, with mine cars or transport vehicles repeatedly traveling on the tracks for transportation, and the transportation efficiency is slow. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a continuous slag discharge device for a subway inclined shaft, which has the advantages of being able to continuously discharge and transport slag, and improving the working efficiency of the slag discharge device.

[0015] Compared with the prior art, the present invention provides a continuous slag discharging device for a subway inclined shaft, which has the following

[0016] Advantages:

[0017] 1. For this continuous slag discharging device for a subway inclined shaft, the ore car uses the jacking frame to discharge slag on the discharge track, uses the limiting frame to roll the ore car onto the inlet track, and then uses the reset frame to reset and roll the ore car onto the discharge track, so that the ore car forms a continuous slag discharging treatment path, improving the working efficiency of the slag discharging device.

[0018] 2. For this continuous slag discharging device for a subway inclined shaft, the motor is set as a servo motor, and the operation mode of the motor is intermittent operation to ensure that the ore car has enough time for treatment when discharging slag on the slope. And the auxiliary roller is set as a double-layer roller structure, and the upper and lower layers of the toothed groove chain respectively pass through the upper and lower layers of the auxiliary roller, so that the auxiliary roller restricts the running path of the toothed groove chain to ensure the stability of the running of the toothed groove chain.

[0029] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a continuous mucking device for a subway inclined shaft.

[0031] In a typical embodiment of the present application, as Figures 1-8 shown, a continuous mucking device for a subway inclined shaft includes an inclined shaft ground 1, a mucking mechanism 2 provided on the inclined shaft ground 1, and a return mechanism 3 provided on the inclined shaft ground 1. The mucking mechanism 2 includes an outgoing track 21 and a mine car 28. The outgoing track 21 is fixedly installed on the inclined shaft ground 1. One end of the outgoing track 21 is located at the top plane of the inclined shaft ground 1, and the other end of the outgoing track 21 is located on the bottom slope of the inclined shaft ground 1. A mine car 28 is provided on the outgoing track 21, and the mine car 28 moves on the outgoing track 21;

[0032] The return mechanism 3 includes an incoming track 31, a pushing frame 32, a limit frame 35, and a return frame 313. The incoming track 31 is fixedly installed on the inclined shaft ground 1. The incoming track 31 is adjacent to the outgoing track 21. One end of the incoming track 31 is located at the top plane of the inclined shaft ground 1. The length of the incoming track 31 on the top plane of the inclined shaft ground 1 is less than the length of the outgoing track 21 on the top plane of the inclined shaft ground 1. The other end of the incoming track 31 is located on the bottom slope of the inclined shaft ground 1. A pushing frame 32 is fixedly installed on the top plane of the inclined shaft ground 1. The pushing frame 32 is adjacent to the outgoing track 21. A limit frame 35 is fixedly installed on the top plane of the inclined shaft ground 1. The limit frame 35 is adjacent to the incoming track 31. A return frame 313 is fixedly installed on the bottom slope of the inclined shaft ground 1. The return frame 313 is adjacent to the incoming track 31.

[0033] When using the present invention:

[0034] After the ore car 28 is filled with slag, start the slag discharging mechanism 2, move the ore car 28 upward from the bottom slope of the inclined shaft ground 1 on the out track 21. When the ore car 28 moves to the top plane of the inclined shaft ground 1, the ore car 28 is restricted by the top moving frame 32 and tilts. After the ore car 28 tilts, the limit frame 35 will resist the ore car 28 to make the ore car 28 unable to continue tilting after generating an inclination angle. Then the ore car 28 stops moving, opens the ore car 28 and discharges the slag under the influence of gravity. Then, the power connection between the ore car 28 and the slag discharging mechanism 2 is released, so that the ore car 28 moves by its own gravity. As the ore car 28 moves and tilts under the influence of its own gravity, the ore car 28 moves along the limit frame 35 and maintains the tilting trend, so as to tilt the ore car 28 onto the in track 31, and make the ore car 28 move from the top plane of the inclined shaft ground 1 to the bottom slope on the in track 31. Then, when the ore car 28 moves to the bottom slope of the inclined shaft ground 1 on the in track 31, the ore car 28 touches the return frame 313, so that the return frame 313 restricts the ore car 28 from tilting onto the out track 21, thereby moving the ore car 28 back onto the out track 21 to reload the slag again, so that the ore car 28 forms a process of one loop, and multiple ore cars 28 can be added during the process to form a continuous slag discharging process;

[0035] The ore car 28 discharges slag on the out track 21 by using the top moving frame 32, rolls the ore car 28 onto the in track 31 by using the limit frame 35, and then rolls the ore car 28 back to the out track 21 by using the return frame 313, so that the ore car 28 forms a continuous slag discharging path, improving the working efficiency of the slag discharging device.

[0036] Further, the slag discharging mechanism 2 further includes a motor 22. The motor 22 is fixedly installed on the top plane of the inclined shaft ground 1. A traction wheel 23 is rotatably fitted on the top plane of the inclined shaft ground 1. The traction wheel 23 faces the out track 21. The traction wheel 23 is power-connected to the motor 22. An auxiliary roller 24 is rotatably fitted at the connection between the top plane and the bottom slope of the inclined shaft ground 1. The auxiliary roller 24 is located between the out tracks 21. A linkage roller 25 is rotatably fitted on the bottom slope of the inclined shaft ground 1. The linkage roller 25 is located between the out tracks 21. A toothed groove chain 26 is tensioned on the traction wheel 23 and the linkage roller 25. The toothed groove chain 26 passes through the auxiliary roller 24.

[0037] Further, the motor 22 is a servo motor, and the operation mode of the motor 22 is intermittent operation to ensure that the ore car 28 has enough time for processing when tilting for slag discharging.

[0038] Further, the auxiliary roller 24 is a double-layer roller structure, and the upper and lower layers of the toothed groove chain 26 respectively pass through the upper and lower layers of the auxiliary roller 24, so that the auxiliary roller 24 restricts the running path of the toothed groove chain 26 and ensures the stability of the running of the toothed groove chain 26.

[0039] Further, a slag discharge chute 27 is provided on the top plane of the inclined shaft ground 1. The slag discharge chute 27 is adjacent to the exit track 21 and one end of the entrance track 31. The width of the slag discharge chute 27 is greater than the length of the mine car 28.

[0040] Further, a main wheel 29 is provided at the bottom end of the mine car 28. The main wheel 29 is adapted to the exit track 21. A pulling hook 210 is rotatably fitted on the mine car 28. One end of the pulling hook 210 is provided with a hook-shaped structure. One end of the pulling hook 210 is adapted to the notch on the toothed groove chain 26, so that the pulling hook 210 is buckled on the toothed groove chain 26 and moves with the rotation of the toothed groove chain 26. A slag discharge door 211 is rotatably fitted on one side surface of the mine car 28. The slag discharge door 211 is used to discharge the ore slag in the mine car 28. The slag discharge door 211 is adjacent to the entrance track 31. A bolt 212 is slidably fitted under the slag discharge door 211. A limit ring 213 is fixedly installed on the mine car 28. The limit ring 213 faces the bolt 212, so that the bolt 212 is inserted into the limit ring 213 to fix the slag discharge door 211. A spring 214 is sleeved on the bolt 212. One end of the spring 214 is connected to the bolt 212, and the other end of the spring 214 is connected to the slag discharge door 211.

[0041] Among them, during the slag discharge process, the motor 22 is started. The motor 22 drives the traction wheel 23 to rotate. The traction wheel 23 drives the toothed groove chain 26 to rotate on the auxiliary roller 24 and the linkage roller 25. The worker picks up the pulling hook 210 and buckles the pulling hook 210 into the groove on the toothed groove chain 26, so that the mine car 28 is driven by the rotation of the toothed groove chain 26 to drive the main wheel 29 to drive the mine car 28 to move on the exit track 21.

[0042] Further, the return mechanism 3 further includes a lifting wheel 33. The lifting wheel 33 is rotatably fitted on the other side surface of the mine car 28. The lifting wheel 33 and the jacking frame 32 are in the same plane. The lifting wheel 33 is adapted to the jacking frame 32. A secondary wheel 34 is provided on one side surface of the mine car 28. The secondary wheels 34 are distributed on both sides of the slag discharge door 211. The secondary wheels 34 are adapted to the entrance track 31. When the mine car 28 moves to the top plane of the inclined shaft ground 1, the lifting wheel 33 and the jacking frame 32 cooperate to tilt the mine car 28, and when the mine car 28 is tilted, the secondary wheels 34 abut against the limit frame 35.

[0043] Among them, as the ore car 28 moves to the top plane of the inclined shaft ground 1, the ore car 28 drives the lifting wheel 33 to touch the top moving frame 32. When the ore car 28 continues to move, the lifting wheel 33 moves along the track of the top moving frame 32, so that the lifting wheel 33 drives the ore car 28 to tilt. As the ore car 28 tilts, the auxiliary wheel 34 touches the limit frame 35, so that the ore car 28 maintains a tilted posture. Then the motor 22 enters intermittent stop, and the worker pulls the bolt 212 to pull the bolt 212 out of the limit ring 213. Under the influence of gravity, the slag discharge door 211 opens, and the ore slag is discharged into the slag discharge trough 27.

[0044] Furthermore, an offset guide rail 36 is fixedly installed on the inclined shaft ground 1. The offset guide rail 36 is located between the exit track 21 and the entrance track 31. The offset guide rail 36 faces the limit frame 35. When the ore car 28 moves from the exit track 21 to the entrance track 31, the offset guide rail 36 assists the auxiliary wheel 34 to align with the entrance track 31.

[0045] Furthermore, a detection controller 37 is fixedly installed on the inclined shaft ground 1. A telescopic rod 38 is fixedly arranged on the detection controller 37. A detection pressure plate 39 is fixedly installed on the extending rod of the telescopic rod 38. The detection pressure plate 39 is signal-connected to the detection controller 37. The detection pressure plate 39 is adjacent to the limit frame 35. When the ore car 28 moves towards the entrance track 31, the auxiliary wheel 34 presses the detection pressure plate 39 on the limit frame 35. An electric control push rod 310 is fixedly installed on the inclined shaft ground 1. The electric control push rod 310 is signal-connected to the detection controller 37. A push plate 311 is fixedly installed on the push rod of the electric control push rod 310. The push plate 311 is used to push the opened slag discharge door 211 back to close it.

[0046] Among them, after the ore slag is discharged, the worker releases the hook between the pulling hook 210 and the toothed groove chain 26. The ore car 28 moves towards the bottom end of the inclined shaft ground 1 under the influence of gravity. At the same time, the ore car 28 moves along the track of the limit frame 35 under the influence of gravity. At the same time, as the ore car 28 moves, the auxiliary wheel 34 touches the offset guide rail 36, so as to roll the ore car 28 onto the entrance track 31, making the auxiliary wheel 34 abut against the entrance track 31. When the ore car 28 rolls, the auxiliary wheel 34 presses the detection pressure plate 39, and the detection pressure plate 39 pushes the telescopic rod 38 to contract, so that the detection controller 37 detects the passing of the ore car 28. The detection controller 37 controls the electric control push rod 310 to start, and the electric control push rod 310 drives the push plate 311 to move, so that the push plate 311 pushes the slag discharge door 211, making the slag discharge door 211 lean against the ore car 28. After the slag discharge door 211 leans against the ore car 28, the elastic force of the spring 214 makes the bolt 212 snap back into the limit ring 213, so as to re-close the slag discharge door 211.

[0047] Further, a friction deceleration strip 312 is fixedly installed on the inlet track 31. The friction deceleration strip 312 is parallel to the inclined end of the inlet track 31 and is used to decelerate the ore car 28 when the ore car 28 moves on the inclined plane at the bottom end of the inclined shaft ground 1.

[0048] Among them, affected by gravity, the ore car 28 uses the auxiliary wheel 34 to move downward on the inlet track 31 towards the bottom end of the inclined shaft ground 1. When on the inclined plane of the inclined shaft ground 1, the auxiliary wheel 34 is affected by the friction deceleration strip 312 to keep the speed of the ore car 28 moving downward not high. Then, the auxiliary wheel 34 touches the return frame 313, and the return frame 313 rolls the ore car 28 back onto the outlet track 21 again, making the main wheel 29 abut against the outlet track 21 again, so that the ore car 28 completes a slag discharging process and can be reloaded with ore slag, effectively improving the working efficiency of the slag discharging device.

[0049] Working principle:

[0050] After the ore car 28 is filled with ore slag, start the slag discharging mechanism 2 to move the ore car 28 upward on the outlet track 21 from the inclined plane at the bottom end of the inclined shaft ground 1. When the ore car 28 moves to the top plane of the inclined shaft ground 1, the ore car 28 is restricted by the pushing frame 32 and tilts. After the ore car 28 tilts, the limiting frame 35 will resist the ore car 28 to make the ore car 28 unable to continue tilting after generating an inclination angle. Then, the ore car 28 stops moving, the ore car 28 is opened and the ore slag is discharged under the influence of gravity. Then, the power connection between the ore car 28 and the slag discharging mechanism 2 is released, and the ore car 28 moves by its own gravity. As the ore car 28 moves and tilts under the influence of its own gravity, the ore car 28 moves along the limiting frame 35 and maintains an inclined trend, so as to tilt the ore car 28 onto the inlet track 31, and make the ore car 28 move from the top plane of the inclined shaft ground 1 to the bottom inclined plane on the inlet track 31. Then, when the ore car 28 moves to the bottom inclined plane of the inclined shaft ground 1 on the inlet track 31, the ore car 28 touches the return frame 313, so that the return frame 313 restricts the ore car 28 from tilting onto the outlet track 21, so as to move the ore car 28 back onto the outlet track 21 to reload the ore slag again, so that the ore car 28 forms a loop processing process, and multiple ore cars 28 can be added during the processing process to form a continuous slag discharging process;

[0051] Among them, during the slag discharging process, start the motor 22. The motor 22 drives the traction wheel 23 to rotate. The traction wheel 23 drives the toothed groove chain 26 to rotate on the auxiliary roller 24 and the linkage roller 25. Manually pick up the pulling hook 210 and buckle the pulling hook 210 into the groove on the toothed groove chain 26, so that the ore car 28 is driven by the rotation of the toothed groove chain 26 to drive the main wheel 29 to drive the ore car 28 to move on the outlet track 21;

[0052] When the ore car 28 moves to the top plane of the inclined shaft ground 1, the ore car 28 drives the lifting wheel 33 to contact the pushing frame 32. When the ore car 28 continues to move, the lifting wheel 33 moves along the track of the pushing frame 32, so that the lifting wheel 33 drives the ore car 28 to tilt. As the ore car 28 tilts, the auxiliary wheel 34 contacts the limiting frame 35, so that the ore car 28 maintains a tilted posture. Then the motor 22 enters intermittent stop, and the worker pulls the bolt 212 to pull the bolt 212 out of the limiting ring 213. Affected by gravity, the slag discharge door 211 opens, and the ore slag is discharged into the slag discharge chute 27;

[0053] After the ore slag is discharged, the worker releases the hook between the pulling hook 210 and the toothed groove chain 26. Affected by gravity, the ore car 28 moves towards the bottom end of the inclined shaft ground 1. At the same time, affected by gravity, the ore car 28 moves along the track of the limiting frame 35. At the same time, as the ore car 28 moves, the auxiliary wheel 34 contacts the offset guide rail 36, so as to roll the ore car 28 onto the inlet track 31, make the auxiliary wheel 34 abut against the inlet track 31, and when the ore car 28 rolls, the auxiliary wheel 34 presses the detection pressure plate 39, and the detection pressure plate 39 pushes the telescopic rod 38 to contract, so that the detection controller 37 detects the passing of the ore car 28. The detection controller 37 controls the electric control push rod 310 to start, and the electric control push rod 310 drives the push plate 311 to move, so that the push plate 311 pushes the slag discharge door 211, making the slag discharge door 211 lean against the ore car 28. After the slag discharge door 211 leans against the ore car 28, the elastic force of the spring 214 makes the bolt 212 snap back into the limiting ring 213, so as to close the slag discharge door 211 again;

[0054] Affected by gravity, the ore car 28 uses the auxiliary wheel 34 to move towards the bottom end of the inclined shaft ground 1 on the inlet track 31. When on the inclined plane of the inclined shaft ground 1, the auxiliary wheel 34 is affected by the friction deceleration belt 312 to keep the speed of the ore car 28 moving downward not high. Then the auxiliary wheel 34 contacts the return frame 313, and the return frame 313 rolls the ore car 28 onto the outlet track 21 again, making the main wheel 29 abut against the outlet track 21 again, so that the ore car 28 completes a slag discharge process and can be reloaded with ore slag.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
