TECHNICAL FIELD

[0001] The present application relates to the technical field of transportation, in particular to an intelligent torque coupling adaptive linkage opening and closing system and control method. BACKGROUND

[0002] In the mining operation, the hoisting system is one of the key links to ensure the normal operation of the mine production, and the cage rocker as an important part of the hoisting system plays a crucial role, which undertakes the safe and efficient transportation task of personnel, materials and the like between the shaft mouth and the underground, and its development and application are closely related to the efficiency and safety of mine production. With the continuous expansion of mining scale and the increase of mining depth, the requirement for the hoisting system is getting higher and higher, which needs to meet the transportation demand of large capacity and high speed, and ensure the safety and stability of operation in complex environment.

[0003] However, in the prior art, the operation of ordinary cage and rocker is generally partially associated automatic operation and partially independent manual operation. Specifically, after the cage is stopped and the rocker is lowered, the cage stopper on the internal track of the cage still needs to be operated independently by manual operation. Due to the narrow space after the mine car is parked in the cage, once the mine car is derailed during manual operation, it is easy to cause crushing accidents, and the safety risk is extremely high. At the same time, for the mine with heavy production task, the manual operation efficiency of the cage stopper is low, which seriously affects the production efficiency of the mine. Therefore, the present application proposes an intelligent torque coupling adaptive linkage opening and closing system and control method. SUMMARY

[0005] In a first aspect, the present application provides an intelligent torque coupling adaptive linkage opening and closing system, comprising a connecting frame and a cage for conveying mine cars, a rocker is rotatably connected to the top end of the connecting frame, and a gas cylinder is rotatably connected to the inside of the connecting frame, the output end of the gas cylinder is hingedly connected to the rocker, and further comprising: At least two groups of car stoppers are arranged on both sides of the cage, the outer side of the car stopper is rotatably connected with a connecting block, the inside of the connecting block is slidably penetrated by a guide plate, and both ends of the guide plate are fixedly connected with the outer side of the cage; An automatic opening and closing mechanism, comprising a trigger assembly and an execution assembly, wherein: The trigger assembly is used to control the execution assembly to operate when the rocker is closed, and the execution assembly is used to control the car stopper to swing so as to release the blocking of the mine car in the cage; A limiting mechanism is connected with the connecting block and is used to lock the connecting block on the outside of the guide plate.

[0006] Optionally, the triggering component includes a pressure transmission rod, a pressure transmission plate, and a guide square tube. The pressure transmission plate is fixed to the bottom end of the pressure transmission rod, and the guide square tube is fixed to the bottom end of the cage. The guide square tube slides through the pressure transmission plate.

[0007] Optionally, the execution component includes a straight groove plate, a main shaft, a cross tube, a torque transmission plate, two sets of connecting rods, a return counterweight, and two sets of support rings. The bottom end of the straight groove plate is attached to the pressure transmission plate. The main shaft is fixedly connected to the inside of the straight groove plate. The cross tube is fixedly connected to the outside of the main shaft. The torque transmission plate is slidably connected to the outside of the cross tube. The two sets of connecting rods are respectively hinged to both ends of the torque transmission plate. The end of the connecting rod away from the torque transmission plate is hinged to the vehicle stop block. The return counterweight is fixedly connected to the outside of the main shaft. Both sets of support rings are rotatably connected to the outside of the main shaft, and the top end of the support ring is fixedly connected to the bottom end of the cage.

[0008] Optionally, the limiting mechanism includes multiple sets of slots, rods, and side plates. The multiple sets of slots are all opened on the side of the guide plate near the vehicle stop block. The rods are slidably connected to the inside of the slots and fixed to the outside of the connecting block. The rods also slide through the side plates.

[0009] Optionally, a pull plate is fixedly connected to the end of the lever away from the slot, and a spring is fixedly connected between the pull plate and the side plate.

[0010] Optionally, wheel stops are provided on both sides of the cage.

[0011] Optionally, a rubber pad is fitted on the end of each of the two sets of vehicle stops away from the connecting rod.

[0012] Optionally, the diameter of the slot is adapted to the diameter of the lever.

[0013] Optionally, a support rod is fixedly connected to the bottom end of the cage, and a magnetic block is fixedly connected to the end of the support rod away from the cage.

[0014] Secondly, the present invention provides a control method for intelligent torque coupling adaptive linkage opening and closing, applied to an intelligent torque coupling adaptive linkage opening and closing system described in the first aspect, the method comprising the following steps: S1, Triggering and transmission: When the rocking table falls and closes, its pressure acts on the pressure transmission rod, pushing the pressure transmission plate to move downward; S2. Unlocking action: The pressure transmission plate presses down on the straight groove plate, driving the main shaft to rotate. This rotation is converted into a pulling force on the two sets of connecting rods through the cross tube and torque transmission plate, thereby pulling the car stop blocks on both sides to swing open and release the obstruction to the mine car. S3. Adaptive adjustment: The lateral position of the car stop block can be adjusted by moving the connecting block laterally according to the position of the mine car, and locked by the engagement of the lever and the slot.

The magnetic block ensures that the return counterweight block stops quickly after resetting.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses a trigger component to sense the rocking platform's movement, which drives the execution component to control the automatic opening and closing of the car's stop blocks, replacing manual entry into the cage and fundamentally eliminating crushing accidents, thus significantly improving operational safety. At the same time, fully automatic operation greatly shortens loading and unloading time and improves the overall efficiency of the hoisting system. The device has a simple and reliable structure, requires no external power, has low manufacturing costs, and is easy to promote in mine shaft cage hoisting systems.

[0016] Furthermore, through the design of the magnetic block, the return counterweight can be magnetically attracted and quickly come to rest when it is reset. This structure effectively eliminates the continuous shaking of the return counterweight caused by inertia, ensuring the accuracy and timeliness of the reset of the transmission components, and improving the stability and reliability of the entire linkage system.

Detailed Implementation

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes an intelligent torque-coupled adaptive linkage opening and closing system, including a connecting frame 1 and a cage 4 for conveying mine cars. A rocking platform 2 is rotatably connected to the top of the connecting frame 1, and a cylinder 3 is rotatably connected inside the connecting frame 1. Both the rocking platform 2 and the cylinder 3 are existing technologies and are mature. The output end of the cylinder 3 is hinged to the rocking platform 2. When the cylinder 3 operates, its output end can drive the rocking platform 2 to swing, so that the rocking platform 2 and the bottom end of the cage 4 are on the same plane. The opening and closing system also includes at least two sets of car stop blocks 5 arranged on both sides of the cage 4. A connecting block 6 is rotatably connected to the side, and the car stop 5 can swing along the inside of the connecting block 6. A guide plate 7 slides through the inside of the connecting block 6, and the connecting block 6 can move laterally along the outside of the guide plate 7. Both ends of the guide plate 7 are fixed to the outside of the cage 4. The cage 4 plays a role in fixing the position of the guide plate 7. When the cage 4 moves up and down, the cage 4 can drive the connecting block 6 to move synchronously through the guide plate 7, so that the car stop 5 can move with the cage 4. It should be noted that the car stop 5 in this embodiment is a cage stopper used to restrict the movement of the mine car.

[0021] As one implementation method, such as Figure 3 - Figure 6 As shown, the opening and closing system also includes an automatic opening and closing mechanism, which includes a trigger component and an execution component. The trigger component controls the execution component to operate when the rocking platform 2 is closed, and when the rocking platform 2 is in a parallel state (e.g., ...). Figure 1 When the rocking platform 2 is in the indicated state, it controls the triggering component to operate. The execution component controls the swing of the car stop 5, causing the car stop 5 to release its obstruction of the mine car inside the cage 4. When the triggering component is running, it drives the execution component to operate, which in turn causes the car stop 5 to swing, thereby releasing its obstruction of the mine car. At this time, the mine car can smoothly enter and exit the cage 4 without the need for personnel to enter the cage 4 for manual operation, thus improving the safety of the device during use. Conversely, when the rocking platform 2 is open (e.g., Figure 4As shown, when the control of the triggering component by the rocking platform 2 is released, the execution component will automatically reset. When the execution component resets, it will drive the car stop 5 to swing in the opposite direction, so that the car stop 5 blocks the mine car. Through the above structural design, the cage 4, the rocking platform 2 and the mine car can be used in a coordinated and synchronous manner. It can form an operation state where the car stop 5 automatically opens after the cage 4 stops and the rocking platform 2 falls, and the car stop 5 automatically falls after the rocking platform 2 is raised. It effectively solves the problem of high safety risks and low production efficiency when manual entry into the cage 4. The use of this device greatly ensures the personal safety of the operators, improves production efficiency and has low processing and manufacturing costs. It is suitable for widespread promotion in the cage 4 hoisting system of various mine shafts.

[0022] Furthermore, such as Figure 4 and Figure 5 As shown, the opening and closing system also includes a limiting mechanism, which is connected to the connecting block 6 and used to lock the connecting block 6 on the outside of the guide plate 7. When the car stop block 5 is moved laterally to adapt to different positions of the mine car, the position of the connecting block 6 can be locked by the limiting mechanism after the connecting block 6 moves along the outside of the guide plate 7. At this time, the lateral position of the connecting block 6 will be restricted, thereby playing a fixing role and ensuring that the position of the car stop block 5 will not shake after adjustment.

[0023] As one implementation method, such as Figure 4 and Figure 6 As shown, the triggering assembly includes a pressure transmission rod 8, a pressure transmission plate 9, and a guide square tube 10. The triggering assembly is described in detail below: The pressure transmission plate 9 is fixed to the bottom end of the pressure transmission rod 8. When the rocking platform 2 falls, it will apply pressure to the pressure transmission rod 8. The guide square tube 10 is fixed to the bottom end of the cage 4. The guide square tube 10 slides through the pressure transmission plate 9. When the pressure transmission rod 8 is under force, it will drive the pressure transmission plate 9 to move down synchronously along the outside of the guide square tube 10.

[0024] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the actuation assembly includes a straight groove plate 11, a main shaft 12, a cross tube 13, a torque transmission plate 14, two sets of connecting rods 15, a return counterweight 16, and two sets of support rings 17. The actuation assembly is described in detail below: The straight groove plate 11 is attached to the bottom end of the pressure transmission plate 9. When the pressure transmission plate 9 moves downward, it applies pressure to the straight groove plate 11. The main shaft 12 is fixedly connected to the inside of the straight groove plate 11, and the force on the straight groove plate 11 will drive the main shaft 12 to rotate. The cross tube 13 is fixedly connected to the outside of the main shaft 12. The rotation of the main shaft 12 will synchronously drive the cross tube 13 to rotate. The torque transmission plate 14 is slidably connected to the outside of the cross tube 13. The rotation of the cross tube 13 will drive the torque transmission plate 14 to rotate. The two sets of connecting rods 15 are respectively hinged to both ends of the torque transmission plate 14. Finally, when the torque transmission plate 14 rotates, it will pull the two sets of connecting rods 15 simultaneously. The end of the connecting rod 15 away from the torque transmission plate 14 is hinged to the vehicle stop block 5. The force on the connecting rod 15 will pull the vehicle stop block. 5. The car stop 5 swings, releasing its obstruction of the mine car, allowing it to move smoothly out of the cage 4. The return counterweight 16 is fixed to the outside of the main shaft 12, and when the main shaft 12 rotates, it also drives the return counterweight 16 to swing. Both sets of support rings 17 are rotatably connected to the outside of the main shaft 12, and the top of the support rings 17 is fixed to the bottom of the cage 4. The two sets of support rings 17 support the main shaft 12, keeping it suspended. When the rocking platform 2 is lifted to release the pressure on the pressure transmission rod 8, the return counterweight 16 will swing back to its original position under the action of gravity. The reverse swing of the return counterweight 16 will drive the main shaft 12 to rotate in the opposite direction, ultimately causing the car stop 5 to swing back to its original position and block the mine car.

[0025] Furthermore, such as Figure 4 and Figure 5 As shown, the limiting mechanism includes multiple sets of slots 18, levers 19, and side plates 20. The limiting mechanism is described in detail below: Multiple sets of slots 18 are provided on the side of the guide plate 7 near the vehicle stop block 5. The locking rod 19 is slidably connected to the inside of the slot 18. In the initial state, the locking rod 19 is located inside the slot 18 and is fixed to the outside of the connecting block 6. The locking rod 19 slides through the side plate 20. Since the side plate 20 is fixed to the locking rod 19, the slot 18 limits the lateral movement of the locking rod 19, thereby fixing the position of the connecting block 6 and limiting the vehicle stop block 5. When it is necessary to move the connecting block 6, that is, change the lateral position of the vehicle stop block 5, the locking rod 19 can be disengaged from the inside of the slot 18. At this time, the limitation of the slot 18 on the locking rod 19 is released, and the connecting block 6 can be moved. It should be noted that the diameter of the slot 18 is matched with the diameter of the locking rod 19. Therefore, when the locking rod 19 is located inside the slot 18, there will be no shaking, which improves the stability of the device during use.

[0026] As one implementation method, such as Figure 5As shown, a pull plate 21 is fixedly connected to the end of the locking rod 19 away from the slot 18. The pull plate 21 facilitates the movement of the locking rod 19. A spring 22 is fixedly connected between the pull plate 21 and the side plate 20. When the pull plate 21 moves, it will also pull the spring 22, causing the spring 22 to deform and generate elastic potential energy. After the connecting block 6 is moved to the appropriate position, the pull plate 21 only needs to be released, and the spring 22 will release its elastic potential energy, pulling the pull plate 21 back to its original position. The resetting of the pull plate 21 will cause the locking rod 19 to be inserted into the slot 18, fixing the position of the connecting block 6. The elastic potential energy of the spring 22 itself can also stabilize the locking rod 19, preventing the locking rod 19 from coming out of the slot 18 under vibration conditions.

[0027] Furthermore, such as Figure 5 and Figure 7 As shown, the cage 4 is provided with wheel stop grooves 23 on both sides. The wheel stop grooves 23 provide space for the swing of the wheel stop block 5, thus avoiding the wheel stop block 5 from "getting stuck" during swing.

[0028] Furthermore, such as Figure 5 As shown, the ends of both sets of car stop blocks 5 away from the connecting rod 15 are fitted with rubber pads 24. The rubber pads 24 can increase the friction when the car stop blocks 5 come into contact with the mine car.

[0029] Among them, such as Figure 7 As shown, a support rod 25 is fixedly connected to the bottom end of the cage 4. A magnetic block 26 is fixedly connected to the end of the support rod 25 away from the cage 4. The support rod 25 supports the magnetic block 26. When the return counterweight 16 is reset, the return counterweight 16 will be attracted by the magnetic block 26, thus sticking together with the magnetic block 26. This avoids the return counterweight 16 from being constantly shaking due to inertia when it is reset. The setting of the magnetic block 26 can make the return counterweight 16 quickly come to a stationary state when it is reset.

[0030] A control method for intelligent torque coupling adaptive linkage opening and closing, the method comprising the following steps: S1. Triggering and transmission: When the rocking table 2 falls and closes, its pressure acts on the pressure transmission rod 8, pushing the pressure transmission plate 9 to move downward; S2. Unlocking action: The pressure transmission plate 9 presses down on the straight groove plate 11, driving the main shaft 12 to rotate. This rotation is converted into a pulling force on the two sets of connecting rods 15 through the cross tube 13 and the torque transmission plate 14, thereby pulling the car stop blocks 5 on both sides to swing open and release the obstruction to the mine car. S3. Adaptive adjustment: The horizontal position of the car stop block 5 can be adjusted by moving the connecting block 6 laterally according to the position of the mine car, and locked by the engagement of the locking rod 19 and the locking slot 18. S4. Reset and lock: When the rocking platform 2 is lifted, the pressure is released, and the return counterweight 16 swings in the opposite direction under the action of gravity, driving the main shaft 12 to move in the opposite direction, so that the car stop 5 automatically swings back to the vertical position and blocks the mine car again. The magnetic block 26 ensures that the return counterweight 16 quickly stops after resetting.

[0031] In this embodiment, when the rocking platform 2 falls and closes under the drive of the cylinder 3, it applies pressure to the pressure transmission rod 8, causing the pressure transmission plate 9 to move downward along the guide square tube 10. The downward pressure of the pressure transmission plate 9 acts on the straight groove plate 11 that is attached to its bottom end, thereby driving the main shaft 12 to rotate. The rotation of the main shaft 12 synchronously drives the cross tube 13 and the return counterweight 16 fixed on it to rotate. The cross tube 13 then drives the torque transmission plate 14 that is slidably connected to its outer side to rotate. The rotation of the torque transmission plate 14 transmits tension through two sets of connecting rods 15 that are hinged to it, causing the car stop block 5 to swing, thereby releasing the obstruction of the mine car in the cage 4 and allowing the mine car to enter and exit smoothly. At this time, the connecting rods 15 are connected to the main shaft 12. The connecting block 6 can move laterally along the guide plate 7 and engage with different slots 18 through the locking rod 19. The limiting mechanism fixes and adapts the lateral position of the car stop block 5. When the work is completed, that is, when the rocking platform 2 is lifted, the pressure on the pressure transmission rod 8 is released. The return counterweight block 16 swings in the opposite direction under the action of gravity, driving the main shaft 12 to rotate in the opposite direction. Then, through the above-mentioned transmission chain, the car stop block 5 swings in the opposite direction to reset and block the mine car again. During the reset process of the return counterweight block 16, the magnetic block 26 can attract and stabilize the return counterweight block 16 to prevent it from affecting the reset accuracy due to shaking. Thus, the system completes an automatic opening and closing cycle and realizes the linkage of the cage 4, the rocking platform 2 and the car stop block 5.

[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
