Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and more specifically to a rail-mounted trolley device. Background Technology

[0002] Mine rail-mounted pushers are commonly used transportation devices in coal mine operations. They are mainly used to dispatch mine cars, flatbed cars, material cars, and other transport vehicles and auxiliary materials at the mine entrance or bottom yard. The rail-mounted pusher is a car handling device used to push mine cars into or out of the cage. The transmission device of existing electric rail-mounted pushers is relatively complex. It transmits power to the drive rope pulley through a reducer, hydraulic coupling, brake mechanism, universal joint, and long drive shaft. The motor, drive wheel, and push claw are all rigidly connected. Once a mine car gets stuck, it will cause the pusher slide to crack or damage the internal parts of the pusher. If the mine car gets stuck, it may even damage the power unit of the electric rail-mounted pusher and burn out the power motor. Once the pusher is damaged, the long repair time will lead to direct economic losses. Summary of the Invention

[0003] This invention provides a rail-mounted trolley device to overcome the drawback that "the rail-mounted trolley will be damaged when the mine car gets stuck".

[0004] The technical solution of the present invention is as follows:

[0005] A rail-mounted trolley device includes a guide rail, within which are mirror-image and equidistantly distributed rollers. A trolley is rotatably connected between the mirror-image and equidistantly distributed rollers. A power box is provided on the guide rail, and a pin wheel is provided within the power box. Equidistantly distributed pin shafts that cooperate with the pin wheel are fixedly connected to the side of the trolley near the pin wheel. A first fixed frame is fixedly connected inside the trolley. A first sliding frame is slidably connected to the side of the first fixed frame away from the adjacent pin shaft. Mirror-image springs are provided between the first sliding frame and the trolley. A rotating shaft is rotatably connected to the side of the first sliding frame away from the first fixed frame. A push plate with a torsion spring is rotatably connected to the rotating shaft. A second sliding frame is slidably connected to the first fixed frame and has a limiting sliding cooperation with the first sliding frame. Mirror-image springs are provided between the second sliding frame and the trolley. A centrally symmetrically distributed first cylinder is fixedly connected inside the trolley. A piston rod that cooperates with the second sliding frame is slidably connected to the first cylinder. A disengagement mechanism is provided inside the first sliding frame.

[0006] Furthermore, a mirror-image and equidistantly distributed first fixed shell is fixedly connected to one side of the first sliding frame near the side of the mirror-image distributed push plate. A buffer block is slidably connected to the first fixed shell. A spring is provided between the first fixed shell and the adjacent buffer block. The buffer block cooperates with the adjacent push plate.

[0007] Furthermore, the disengagement mechanism includes a mirror-distributed third sliding frame, each of which is slidably connected within the first sliding frame. A spring is provided between the third sliding frame and the first sliding frame. A mirror-distributed first limiting block is fixedly connected to the first fixed frame, and the first limiting block engages with the adjacent third sliding frame. A mirror-distributed second limiting block is slidably connected to the second sliding frame, and a spring is provided between the second limiting block and the second sliding frame. The second limiting block engages with the first sliding frame and contacts the adjacent third sliding frame. A second fixed frame is fixedly connected to the side of the first sliding frame away from the first fixed frame. The second fixed frame is provided with mirror-distributed pressure monitors, each of which engages with the second sliding frame.

[0008] Furthermore, the force provided by the spring between the second sliding frame and the trolley is greater than the sliding friction force experienced by the mine car when it moves, in order to ensure the normal use of the trolley.

[0009] Furthermore, it also includes a booster mechanism, which is disposed on the first fixed frame. The booster mechanism includes centrally symmetrically distributed second cylinders, each of which is fixed to the side of the first fixed frame away from the first sliding frame. The second cylinders are connected to an air supply pipe. A centrally symmetrically distributed second fixed shell is fixedly disposed inside the trolley. A first sliding block is slidably connected inside the second fixed shell. The first sliding block cooperates with the guide rail. A spring is disposed between the first sliding block and the adjacent second fixed shell. A fourth sliding frame is fixedly disposed to the first sliding block. The fourth sliding frame is slidably connected to the trolley. A centrally symmetrically distributed fixed sleeve is fixedly disposed inside the trolley. The fixed sleeve is slidably connected to the adjacent fourth sliding frame. The air supply pipe is connected to the adjacent fixed sleeve. A mirror-distributed connecting pipe is connected to the side of the fixed sleeve away from the adjacent air supply pipe. The connecting pipe is connected to the adjacent first cylinder. The trolley is provided with a pressure boosting mechanism.

[0010] Furthermore, both the fourth sliding frame and the fixed sleeve are provided with mirror-distributed through holes, and the distance between adjacent through holes on the fourth sliding frame is smaller than the distance between adjacent through holes on the fixed sleeve.

[0011] Furthermore, in the mirror-distributed connecting pipes, the distance between the connecting pipe furthest from the adjacent air supply pipe and the adjacent end of the adjacent first cylinder is greater than the thickness of the sliding portion of the piston rod located in the adjacent first cylinder, in order to ensure normal depressurization of the first cylinder.

[0012] Furthermore, the boosting mechanism includes equidistantly distributed first sliding plates, each equidistantly distributed first sliding plate being slidably connected to the side of the trolley near the equidistantly distributed pins. Adjacent first sliding plates are fixedly connected to each other via mounting brackets. Equidistantly distributed second sliding plates are slidably connected to the side of the trolley near the equidistantly distributed pins, adjacent second sliding plates being fixedly connected to each other via mounting brackets. The equidistantly distributed first and second sliding plates are staggered. Springs are provided between each of the first and second sliding plates and the trolley. Equally spaced and centrally symmetrically distributed limiting frames are slidably connected to one side of the equally spaced pins. Among the equally spaced limiting frames, one limiting frame is fixedly connected to the adjacent first sliding plate, and the other limiting frame is fixedly connected to the adjacent second sliding plate. An equally spaced and centrally symmetrically distributed air pump is provided on one side of the first fixed frame near the equally spaced pins. The air pump is connected to the adjacent second cylinder through a pipe. A rotating rod is fixedly connected to the movable end of the air pump. The rotating rod is in a limiting engagement with the adjacent limiting frame. A pressure stabilizing valve is provided on the second cylinder.

[0013] Furthermore, it also includes a reversing mechanism, which is disposed on the second fixed frame. The reversing mechanism includes a throttle, which is rotatably connected to the side of the second fixed frame away from the first sliding frame. The second fixed frame is rotatably connected to a threaded rod via a mounting plate. The throttle and the threaded rod are driven by a bevel gear set. The second fixed frame is slidably connected to a second sliding block. A mirror-distributed spring is disposed between the second sliding block and the second fixed frame. A rack is disposed on the side of the second sliding block near the rotating shaft. The second sliding block is slidably connected to a fifth sliding frame. The threaded rod is threadedly engaged with the fifth sliding frame. A gear is fixedly connected to the rotating shaft. The gear meshes with the rack of the second sliding block.

[0014] Furthermore, a third fixed frame is fixedly connected to one side of the third sliding frame, the third fixed frame is slidably connected to the first sliding frame, and the side of the fifth sliding frame away from the threaded rod is slidably connected to the third fixed frame.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0016] This invention uses a first sliding frame and a second sliding frame to buffer the mine car, preventing a hard collision between the pusher and the mine car when the mine car gets stuck, thus ensuring the safety of the pusher. By adjusting the state of the first and second sliding frames, when the mine car gets stuck, the force between the pusher and the mine car is reduced immediately, thus preventing the power box from burning out due to the mine car getting stuck. By using a first sliding block and a fourth sliding frame to change the connection state between the second cylinder and the adjacent first cylinder, the pusher provides an instantaneous acceleration before pushing the mine car to the cage, ensuring the mine car enters the cage stably, eliminating the need for manual assistance and improving the practicality of the device. By using a third fixed frame and a fifth sliding frame, the pusher plate retracts after the mine car gets stuck, causing the pusher to lose its pushing force on the mine car, thus protecting the pusher and further ensuring the safety of the pusher during operation.

[0031] A rail-mounted trolley device, please refer to Figures 1-5The system includes a guide rail 1, with four mirror-image and equidistantly distributed rollers 2 on the inner side of the guide rail 1. A trolley 3 for pushing a mine car is rotatably connected between the four rollers 2. A power box 4 is located below the guide rail 1, with pin wheels 5 on the inner side of the power box 4. Pin shafts 6, equidistantly distributed in the left-right direction, are fixedly connected to the lower side of the trolley 3. The pin wheels 5 cooperate with the equidistantly distributed pin shafts 6 to drive the trolley 3 to move. A first fixed frame 7 is fixedly connected to the inner side of the trolley 3. The vertical section of the first fixed frame 7 is H-shaped. A first sliding frame 8, with a horizontal section of the first sliding frame 8, is slidably connected to the upper side of the first fixed frame 7. Springs are installed on both sides of the first sliding frame 8 between it and the trolley 3. A rotating shaft 801 is rotatably connected to the upper side of the first sliding frame 8. Push plates 9 are rotatably connected to both sides of the rotating shaft 801. The push plates 9 are right-angled triangular blocks with protrusions at two acute angles. Torsion springs are installed between the rotating shaft 801 and the two push plates 9. A second sliding frame 10 is slidably connected to the upper side of the first fixed frame 7. The vertical section of the second sliding frame 10 is U-shaped. Springs are installed on both sides of the second sliding frame 10 between it and the trolley 3. Both the first sliding frame 8 and the second sliding frame 10 are located inside the trolley 3. The trolley 3 is fitted with a limiting sliding engagement with the second sliding frame 10. A centrally symmetrically distributed first cylinder 11 is fixedly connected to the inner side of the trolley 3. The first cylinder 11 provides cushioning for the trolley 3. A piston rod 12 is slidably connected to the first cylinder 11. The piston rod 12 engages with the second sliding frame 10. When the second sliding frame 10 moves to the right, it presses the right piston rod 12 to the right. When the second sliding frame 10 moves to the left, it presses the left piston rod 12 to the left. Four mirror-image and equidistantly distributed first fixed shells 13 are fixedly connected to the upper side of the first sliding frame 8. The inner side of the first fixed shell 13 slides... The device is dynamically connected with buffer blocks 14. The two front buffer blocks 14 are on the same vertical plane as the front push plate 9, and the two rear buffer blocks 14 are on the same vertical plane as the rear push plate 9. A spring is provided between the first fixed shell 13 and the adjacent buffer block 14 to provide buffering for the adjacent push plate 9. The buffer block 14 cooperates with the adjacent push plate 9. When the push plate 9 rotates, the lower side of the push plate 9 contacts the adjacent buffer block 14 and squeezes the spring between the buffer block 14 and the adjacent first fixed shell 13. The inner side of the first sliding frame 8 is provided with a disengagement mechanism 15 for controlling the cooperation relationship between the first sliding frame 8 and the second sliding frame 10.

[0032] Please see Figure 5The disengagement mechanism 15 includes two third sliding frames 1501 arranged in a mirror image. Each third sliding frame 1501 is a U-shaped frame with a protrusion in the middle. Both third sliding frames 1501 are slidably connected to the inner side of the first sliding frame 8. A spring is provided between the third sliding frame 1501 and the first sliding frame 8. A mirror image first limiting block 1502 is fixedly connected to the upper side of the first fixed frame 7. The cross-section of the first limiting block 1502 is a right trapezoid. The protrusion in the middle of the first limiting block 1502 is in a limiting engagement with the adjacent third sliding frame 1501. Second limiting blocks 1503 are slidably connected to the left and right sides of the second sliding frame 10, arranged in a mirror image. A spring is provided between the second limiting block 1503 and the second sliding frame 10. The cross-section of the second limiting block 1503 is a right trapezoid. The second limiting block 1503 is in a limiting engagement with the first sliding frame 8. The second limiting block 1503 contacts and engages with the adjacent third sliding frame 1501. When the third sliding frame 1501 moves toward the second sliding frame 10, the third sliding frame 1501 presses the adjacent second limiting block 1503 into the second sliding frame 10 until the second limiting block 1503 loses its limiting engagement with the first sliding frame 8. A second fixed frame 1504 is fixedly connected to the upper side of the first sliding frame 8. Pressure monitors 1505 for monitoring pressure changes are provided on both the left and right sides of the second fixed frame 1504. The mirror-distributed pressure monitors 1505 engage with the second sliding frame 10. The force provided by the spring between the second sliding frame 10 and the pusher 3 is greater than the sliding friction force experienced when the mine car moves. This ensures that when the pusher 3 pushes the mine car to move normally, the protrusion in the middle of the third sliding frame 1501 will not contact the first limiting block 1502, thus ensuring the normal use of the pusher 3.

[0033] When the user needs to use this device to push the mine car (e.g.) Figure 1 As shown), the user controls the pin wheel 5 to rotate through the power box 4. The pin wheel 5 cooperates with the pin shafts 6 that are equidistantly distributed on the lower side of the trolley 3 and drives the trolley 3 to move to the left. The trolley 3 drives the first sliding frame 8 to move to the left synchronously through the spring between the first sliding frame 8 and the trolley 3. The first sliding frame 8 drives the two push plates 9 to move to the left through the rotating shaft 801 until both push plates 9 contact the right side of the mine car.

[0034] After both push plates 9 come into contact with the right side of the mine car, the pin wheel 5 continues to drive the push car 3 and the two push plates 9 to move to the left through the pin shaft 6. The push plates 9 are subjected to the reaction force of the mine car and swing to the right, squeezing the two buffer blocks 14 on the right side to move downward. The buffer blocks 14 squeeze the spring between themselves and the adjacent first fixed shell 13 and buffer the push plates 9.

[0035] During the buffering process of the buffer block 14 on the adjacent push plate 9, the mine car drives the first sliding frame 8 to move to the right through the two push plates 9 and the rotating shaft 801, squeezing the spring between the right side of the first sliding frame 8 and the push car 3, and stretching the spring between the left side of the first sliding frame 8 and the push car 3. The first sliding frame 8 drives the second sliding frame 10 to move to the right synchronously through the four second limit blocks 1503, squeezing the spring between the right side of the second sliding frame 10 and the push car 3, and stretching the spring between the left side of the second sliding frame 10 and the push car 3. Through the springs between the first sliding frame 8 and the second sliding frame 10 and the push car 3, the mine car is positioned relative to the push plate 9 and the push car 3. The force of contact is buffered, and the second sliding frame 10 drives the piston rod 12 on the right to move to the right and squeeze the air between the right end of the piston rod 12 and the first cylinder 11, which buffers the second sliding frame 10 again until the sum of the elastic forces of the springs between the first sliding frame 8, the second sliding frame 10 and the pusher 3 is equal to the sliding friction force of the mine car on the track. At this time, the relative positions of the first sliding frame 8, the second sliding frame 10 and the pusher 3 remain unchanged. Then the user controls the pusher 3 to push the mine car until the mine car is pushed into the cage. The user controls the pusher 3 to reset through the power box 4 and the pin wheel 5. At this time, the work is completed.

[0036] During the process of the pusher 3 pushing the mine car to move, the pusher 3 drives the first sliding frame 8 and the second sliding frame 10 to move to the left. If the mine car gets stuck, the resistance to the leftward movement of the mine car increases. At this time, the reaction force of the mine car on the pusher 3 increases. The mine car drives the first sliding frame 8 and the second sliding frame 10 to move to the right through the pusher plate 9. At the same time, it squeezes the spring between the right side of the first sliding frame 8 and the second sliding frame 10 and the pusher 3. The second sliding frame 10 drives the piston rod 12 on the right side to move to the right and squeezes the air in the first cylinder 11 on the right side located to the right of the piston rod 12. This buffers the increased reaction force of the mine car and prevents damage caused by hard collisions between the parts inside the pusher 3.

[0037] During the process of the pusher 3 pushing the mine car to move, the pusher 3 drives the first sliding frame 8 and the second sliding frame 10 to move to the left. If the mine car gets stuck, it cannot continue to move to the left. At this time, the reaction force of the mine car on the pusher 3 increases instantaneously. The mine car drives the first sliding frame 8 and the second sliding frame 10 to move to the right through the push plate 9. The first sliding frame 8 drives the third sliding frame 1501 to move to the right at the same time, and squeezes the spring between the first sliding frame 8, the second sliding frame 10 and the right side of the pusher 3. The second sliding frame 10 drives the piston rod 12 on the right side to move to the right and squeezes the air in the first cylinder 11 on the right side located to the right of the piston rod 12, which buffers the instantaneous increase in reaction force of the mine car until the protrusion on the front side of the middle of the third sliding frame 1501 contacts the inclined surface of the first limit block 1502 on the right side.

[0038] When the protrusion on the front side of the middle part of the third sliding frame 1501 contacts the inclined surface of the first limiting block 1502 on the right side, taking the front side as an example, as the first sliding frame 8 continues to drive the third sliding frame 1501 to move to the right, the first limiting block 1502 on the right side squeezes the third sliding frame 1501 to move backward. The third sliding frame 1501 squeezes the front second limiting block 1503 backward and squeezes the spring between the front second limiting block 1503 and the second sliding frame 10 until all the second limiting blocks 1503 have moved into the second sliding frame 10. At this time, the second limiting blocks 1503 lose their limiting effect on the first sliding frame 8.

[0039] When the second limiting block 1503 loses its limiting effect on the first sliding frame 8, the first sliding frame 8 changes from a state of joint movement to a state of free sliding. The first cylinder 11 on the right drives the second sliding frame 10 to move to the left and reset. The two second limiting blocks 1503 on the left lose their limiting effect on the first sliding frame 8 and are driven outward by the spring between the second limiting block 1503 and the second sliding frame 10. Meanwhile, the two second limiting blocks 1503 on the right are still limited by the first sliding frame 8. At this time, the pushing force of the push plate 9 on the mine car is only provided by the spring between the first sliding frame 8 and the push car 3. The push plate 9 drives the first sliding frame 8 to continue moving to the right and compresses the spring between the right side of the first sliding frame 8 and the push car 3. While buffering the push car 3 and the mine car, the magnitude of the buffering force is reduced immediately. As the first sliding frame 8 continues to move to the right... The second sliding frame 10 moves to the right and resets to the left. The second sliding frame 10 contacts and presses against the pressure monitor 1505 on the right side. The pressure monitor 1505 detects a sudden increase in pressure and controls the power box 4 to cut off the power of the pin wheel 5 while simultaneously issuing an alarm. The pin wheel 5 stops driving the pusher 3, thus preventing the power box 4 from burning out due to the mine car jamming. Subsequently, the user notifies maintenance personnel to come and inspect and repair the vehicle. The first sliding frame 8 and the second sliding frame 10 work together to buffer the mine car, preventing a hard collision between the pusher 3 and the mine car when the mine car jams, thus ensuring the safety of the pusher 3. By adjusting the state of the first sliding frame 8 and the second sliding frame 10, the force between the pusher 3 and the mine car is reduced immediately when the mine car jams, thus preventing the power box 4 from burning out due to the mine car jamming.

[0040] After maintenance, the maintenance personnel removed the mine car. The spring between the first sliding frame 8 and the pusher 3 caused the first sliding frame 8 and the push plate 9 to move to the left and reset. During the leftward movement of the first sliding frame 8, the two second limit blocks 1503 on the left side contacted the inclined surface on the left side of the first sliding frame 8 and squeezed the second limit blocks 1503 to move towards the second sliding frame 10, compressing the spring between the second limit blocks 1503 and the second sliding frame 10 until the second sliding frame 10 and the first sliding frame 8 were reset. At this time, the four second limit blocks 1503 simultaneously extended outward and embedded in the first sliding frame 8, locking the relative position of the first sliding frame 8 and the second sliding frame 10. The reset was then complete, and the user continued to control the pusher 3 to work. Example

[0041] Based on Example 1, please refer to Figure 3 , Figure 6 and Figure 7It also includes a booster mechanism 16 for pushing the mine car. The booster mechanism 16 is located on the lower side of the first fixed frame 7. The booster mechanism 16 includes two second cylinders 1601 that are centrally symmetrically distributed. Both second cylinders 1601 are used to provide boosting force. Both second cylinders 1601 are fixed to the first fixed frame 7. Air supply pipes 1602 are connected to the opposite sides of the two second cylinders 1601. Two second fixed shells 1603 that are centrally symmetrically distributed are fixed to the inner side of the pusher 3. A first sliding block 1 is slidably connected to the inner side of each of the two second fixed shells 1603. 604, the first sliding block 1604 cooperates with the guide rail 1. When the trolley 3 moves to the end of the guide rail 1, the guide rail 1 contacts and presses the adjacent first sliding block 1604 to move into the trolley 3. A spring is provided between the first sliding block 1604 and the adjacent second fixed shell 1603, and the spring between the first sliding block 1604 and the adjacent second fixed shell 1603 is located inside the second fixed shell 1603. A fourth sliding frame 1605 is fixedly connected to one end of the first sliding block 1604 located inside the adjacent second fixed shell 1603. The fourth sliding frame 1605 is slidably connected to the trolley 3. Next, the fourth sliding frame 1605 consists of an L-shaped rod and a straight plate. A centrally symmetrically distributed fixed sleeve 1606 is fixedly connected to the inner side of the trolley 3. The fixed sleeve 1606 is a rectangular sleeve and is slidably connected to the straight plate portion of the adjacent fourth sliding frame 1605. The opposite ends of the two air supply pipes 1602 are respectively connected to the adjacent fixed sleeve 1606. Two mirror-distributed connecting pipes 1607 are connected to the upper side of the fixed sleeve 1606. The connecting pipes 1607 are connected to the adjacent first cylinder 11. The trolley 3 is equipped with a device for supplying air to the second… The cylinder 1601 provides a pressure boosting mechanism 17. The straight plate portion of the fourth sliding frame 1605 and the fixed sleeve 1606 are both provided with two through holes distributed in a mirror image. The distance between adjacent through holes on the fourth sliding frame 1605 is less than the distance between adjacent through holes on the fixed sleeve 1606. The distance between the connecting pipe 1607, which is far from the adjacent air supply pipe 1602, and the adjacent end of the adjacent first cylinder 11 is greater than the thickness of the sliding portion of the piston rod 12 located in the adjacent first cylinder 11, in order to ensure that the first cylinder 11 can depressurize normally.

[0042] Please see Figure 3 and Figure 8The boosting mechanism 17 includes first sliding plates 1701 equidistantly distributed in the left-right direction. Each of the equidistant first sliding plates 1701 is slidably connected to the lower side of the trolley 3. Adjacent first sliding plates 1701 are fixedly connected by mounting brackets. Second sliding plates 1702 equidistantly distributed in the left-right direction are slidably connected to the lower side of the trolley 3. Adjacent second sliding plates 1702 are fixedly connected by mounting brackets. The equidistant first sliding plates 1701 and equidistant second sliding plates 1702 are staggered in the left-right direction. Springs are provided between the first sliding plates 1701 and second sliding plates 1702 and the trolley 3. Equidistant and centrally symmetrically distributed limiting brackets 1703 are slidably connected to the lower side of the trolley 3. The limiting brackets 1703 are provided with inclined sliding grooves in the same left-right direction. Of the two limiting frames 1703, one limiting frame 1703 is fixedly connected to the adjacent first sliding plate 1701, and the other limiting frame 1703 is fixedly connected to the adjacent second sliding plate 1702. Four air pumps 1704 are equidistantly and centrally symmetrically distributed on the lower side of the first fixed frame 7. The air pumps 1704 are existing technology and will not be described in detail here. Two air pumps 1704 in the same left-right direction are respectively connected to the second cylinder 1601 in the same left-right direction through pipes. The movable end of the air pump 1704 is fixedly connected to a rotating rod 1705. The rotating rod 1705 is limited and engaged with the inclined sliding groove on the adjacent limiting frame 1703. The second cylinder 1601 is equipped with a pressure regulating valve 1706. The pressure regulating valve 1706 is existing technology and will not be described in detail here.

[0043] When the user controls the trolley 3 to move the mine car via the push plate 9, the pin wheel 5 gradually engages with the equally spaced pin shafts 6 and alternately presses against the first sliding plate 1701 and the second sliding plate 1702 (to...). Figure 7 (Taking the middle group as an example), when the pin wheel 5 presses the first sliding plate 1701 to move upward, the first sliding plate 1701 drives the equally distributed first sliding plates 1701 to move upward simultaneously through the mounting rod, and presses the spring between the first sliding plate 1701 and the trolley 3. The first sliding plate 1701 drives the right limit frame 1703 to move upward. The right rotating rod 1705, due to the limitation of the adjacent limit frame 1703, drives the movable end of the right air pump 1704 to move to the left, and fills the second cylinder 1601 on the left. Air is introduced, and then the pin wheel 5 presses the second sliding plate 1702 upward. At this time, the spring between the first sliding plate 1701 and the trolley 3 drives the first sliding plate 1701 and the movable end of the left limit frame 1703, the rotating rod 1705 and the air pump 1704 to reset. When the pin wheel 5 presses the second sliding plate 1702 upward, similarly, the second sliding plate 1702 is filled with air into the left second cylinder 1601 through the right limit frame 1703, the right rotating rod 1705 and the right air pump 1704.

[0044] During the process of continuously filling the second cylinder 1601 with air, the air pressure in the second cylinder 1601 continuously increases. When the air pressure in the second cylinder 1601 increases to the set value of the pressure regulating valve 1706, the pressure regulating valve 1706 discharges the gas in the second cylinder 1601 to the outside, so that the air pressure in the second cylinder 1601 is maintained at a constant value.

[0045] When the trolley 3 pushes the mine car to move into the cage (i.e., when the trolley 3 is about to move to the end of the guide rail 1, taking the first sliding block 1604 on the left as an example), as the trolley 3 continues to move to the left, the trolley 3 causes the first sliding block 1604 on the right to contact and press against the left end of the guide rail 1. The first sliding block 1604 is pressed to the right by the guide rail 1 and presses the spring between the first sliding block 1604 and the second fixed shell 1603. The first sliding block 1604 causes the adjacent fourth sliding frame 1605 to move to the right until the through hole on the right side of the fourth sliding frame 1605 is aligned with the through hole on the right side of the fixed shell 1606. At this time, the through hole on the left side of the fourth sliding frame 1605 and the through hole on the left side of the adjacent fixed shell 1606 are no longer connected. The second cylinder 1601 on the right side is connected to the adjacent air supply pipe 1602, the fourth sliding frame 1605, the fixed shell 1606 and the right side. The connecting pipe 1607 is connected to the first cylinder 11 on the right. The high-pressure air in the second cylinder 1601 on the right enters the first cylinder 11 on the right through the air supply pipe 1602, the fourth sliding frame 1605, the fixed sleeve 1606 and the connecting pipe 1607 on the right. The air pressure in the first cylinder 11 suddenly increases and squeezes the right piston rod 12 to move to the left. The right piston rod 12 drives the push plate 9 to move to the left through the second sliding frame 10 and the first sliding frame 8 and pushes the mine car to the left, providing instantaneous acceleration for the mine car and enabling the mine car to enter the cage smoothly. By cooperating with the first sliding block 1604 and the fourth sliding frame 1605, the connection state between the second cylinder 1601 and the adjacent first cylinder 11 is changed, so that the pusher 3 provides instantaneous acceleration before pushing the mine car to the cage, ensuring that the mine car enters the cage stably, reducing the manual assistance link and improving the practicality of the device.

[0046] After the pusher plate 9 pushes the mine car to the left, the user controls the pusher 3 to move to the right through the power box 4 and the pin wheel 5. The spring between the second fixed shell 1603 and the first sliding block 1604 drives the first sliding block 1604 and the fourth sliding frame 1605 to move to the left and reset. After the fourth sliding frame 1605 resets, it re-isolates the second cylinder 1601 on the right side from the first cylinder 11 on the right side. At the same time, the connecting pipe 1607 on the left side connects the first cylinder 11 to the outside. Then, the high-pressure gas in the first cylinder 11 is discharged to the outside through the connecting pipe 1607 on the left side. The spring between the second sliding frame 10 and the pusher 3 drives the second sliding frame 10 and the right piston rod 12 to move to the right and reset until the right piston rod 12 is reset. At this time, the right piston rod 12 blocks the left connecting pipe 1607, and the air pressure in the first cylinder 11 returns to normal pressure. The reset is then complete, and the user continues to control the pusher 3 to work. Example

[0047] Based on Example 2, please refer to Figure 5 and Figures 9-11 It also includes a reversing mechanism 18 for changing the rotation angle of the push plate 9. The reversing mechanism 18 is disposed on the second fixed frame 1504. The reversing mechanism 18 includes a handle 1801, which is rotatably connected to the upper side of the second fixed frame 1504. The second fixed frame 1504 is rotatably connected to a threaded rod 1802 via a mounting plate. The lower end of the handle 1801 and the right end of the threaded rod 1802 are driven by a bevel gear set. A straight slide groove is provided in the middle of the second fixed frame 1504. A second sliding block 1803 is slidably connected in the straight slide groove of the second fixed frame 1504. Springs are provided on both the left and right sides of the second sliding block 1803 and the second fixed frame 1504. The second sliding block 1803 and the second fixed frame The spring constant between 1504 is greater than the spring constant between the first sliding frame 8 and the trolley 3. A rack is provided on the lower side of the second sliding block 1803. The inner side of the second sliding block 1803 is slidably connected to the fifth sliding frame 1804, which is threadedly engaged with the threaded rod 1802. A gear 1805 is fixedly connected to the middle of the rotating shaft 801. The gear 1805 meshes with the rack of the second sliding block 1803. A third fixed frame 1806 is fixedly connected to the middle of the third sliding frame 1501 on the front side. The third fixed frame 1806 is slidably connected to the first sliding frame 8. The third fixed frame 1806 consists of two L-shaped rods and a rectangular frame. The front side of the fifth sliding frame 1804 is slidably connected to the rectangular frame part of the third fixed frame 1806.

[0048] When the user needs to reverse the direction of the mine car, the user first turns the throttle 1801. The throttle 1801 drives the threaded rod 1802 to rotate through the bevel gear set. The rotation of the threaded rod 1802 drives the second sliding block 1803 to move to the left through the fifth sliding frame 1804. The lower teeth of the second sliding block 1803 mesh with the gear 1805 and drive the gear 1805 and the rotating shaft 801 to rotate. The rotating shaft 801 drives the push plate 9 to rotate through the torsion spring until the second sliding block 1803 moves to the middle of the fifth sliding frame 1804. At this time, the fifth sliding frame 1804 and the push plate 9 rotate. The springs on both sides of the second sliding block 1803 are in normal condition, and the upper side of the push plate 9 is parallel to the horizontal plane. As the second sliding block 1803 continues to move to the left, the second sliding block 1803 compresses the spring between the left side of the second sliding block 1803 and the second fixed frame 1504, and stretches the spring between the right side of the second sliding block 1803 and the second fixed frame 1504, until the second sliding block 1803 moves to the left to its limit position. At this time, the push plate 9 rotates 90 degrees, and the reversal is completed. Then the user controls the trolley 3 to continue working.

[0049] When the mine car jams and the third sliding frame 1501 moves towards the second sliding frame 10 due to the limitation of the adjacent first limiting block 1502, the front third sliding frame 1501 drives the third fixed frame 1806 to move backward. The third fixed frame 1806 drives the fifth sliding frame 1804 to move backward. At this time, the fifth sliding frame 1804 loses its threaded engagement with the threaded rod 1802. The spring between the second sliding block 1803 and the second fixed frame 1504 drives the second sliding block 1803 to move to the right until the second sliding block 1803 moves to the middle of the second fixed frame 1504. During this process, the lower teeth of the second sliding block 1803 mesh with the gear 1805 and drive the rotating shaft 801 to rotate. The rotating shaft 801 drives the push through the torsion spring. The push plate 9 rotates, causing its inclined surface to coincide with the horizontal plane. Because the elastic coefficient of the spring between the second sliding block 1803 and the second fixed frame 1504 is greater than that between the first sliding frame 8 and the push car 3, during the rotation of the push plate 9, the push plate 9 drives the first sliding frame 8 to move to the right and compresses the spring between the right side of the first sliding frame 8 and the push car 3 until the inclined surface of the push plate 9 coincides with the horizontal plane. At this time, the push plate 9 loses contact with the mine car, eliminating the force between the mine car and the push car 3. Through the cooperation of the third fixed frame 1806 and the fifth sliding frame 1804, the push plate 9 is retracted after the mine car jams, causing the push car 3 to lose its pushing force on the mine car, thereby protecting the push car 3 and further ensuring the safety of the push car 3 during operation.
