Technical Field
[0001] This invention belongs to the technical field of mine car blocking equipment, specifically a mine car blocking device. Background Technology
[0002] A mining area refers to a coalfield or a portion thereof that is planned and developed in a unified manner. It includes an area with several mine shafts or open-pit mines, possessing complete production processes, surface transportation, power supply, communication dispatching, production management, and living services. Its scope often depends on the size of the deposit. Gold mines refer to gold ore or gold deposits (mountains). Gold ore is a mineral aggregate containing sufficient gold content for industrial use. A gold mine is a place where gold is obtained through mining operations; it is a sizable accumulation of industrially usable gold ore formed through mineralization. In gold mining, mine cars are generally used to transport personnel and ore. These mine cars typically run on tracks that connect the mine to external access roads. Because the external environment is close to roads, mine cars are prone to collisions with pedestrians or vehicles after leaving the mine. Therefore, a mine car stop device is needed to prevent this.
[0003] Because mine cars transport ore or construction workers, their full load weight is considerable. Collisions between mine cars and pedestrians or vehicles as they exit the mine can lead to serious accidents. Current technology typically uses manually controlled barriers to stop the mine cars. When a mine car is about to enter the external road, the barrier drops to stop it. However, due to the significant weight of the mine cars, they continue to move forward a certain distance due to inertia even after stopping. Therefore, braking distance must be controlled to prevent collisions with the barrier. Otherwise, a collision can damage the barrier or, in severe cases, cause injury to personnel or cargo inside the mine car due to the impact force, posing a high risk and urgently requiring improvement.
[0004] When a mine car travels into the external environment and it is confirmed that there are no personnel or vehicles crossing the track, the safety of the travel route should be ensured. At this point, the barrier should be opened to allow the mine car to continue moving and fulfill the need for carrying people and goods. However, once the mine car has moved away from the barrier, in order to block subsequent mine cars, the barrier usually needs to be manually lowered by the construction personnel to continue blocking the cars. Obviously, the level of intelligence is low, and the subsequent blocking function often fails because the construction personnel forget to lower the barrier. The level of automation is also low. Summary of the Invention
[0005] The purpose of this invention is to provide a mine car blocking device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a mine car stopping device, comprising a base, a track laid in the middle of the top of the base, fixed seats installed on the left and right sides of the top of the base located on both sides of the track, a sliding groove opened at the relatively close end of each of the two fixed seats, a brake assembly movably engaged inside the sliding groove, a vertical rod fixedly installed at the end of the fixed seat away from the brake assembly, a stopping assembly provided at the right end of the vertical rod, an oil storage pipe provided at the right end of each of the two fixed seats, the oil storage pipe being connected to the base through a connecting seat, an output pipe fixedly connected at the end of the oil storage pipe away from the fixed seat, a temporary storage tank fixedly connected at the other end of the output pipe, the temporary storage tank being fixedly connected to the base through a connecting seat, a cleaning assembly provided between the stopping assembly and the temporary storage tank, and a movable rod located inside the sliding groove fixedly installed at the end of the brake assembly near the vertical rod.
[0007] As a further technical solution of the present invention, the end of the movable rod away from the brake assembly passes through one end of the fixed seat and one end of the oil reservoir and is located inside the oil reservoir. A piston plate located inside the oil reservoir is fixedly installed at the end of the movable rod away from the brake assembly, and the piston plate and the oil reservoir are movably connected.
[0008] As a further technical solution of the present invention, a second limiting spring is movably sleeved on the outer side of the movable rod, and the left and right ends of the second limiting spring are respectively fixedly connected to one end of the inner cavity of the slide groove and one end of the brake assembly.
[0009] Before using the device, the two sets of devices must be installed on the left and right sides of the base, i.e., on the left and right sides of the track. The brake assembly must be able to block the mine car according to the size of the mine car. At the same time, the oil storage pipe must be filled with hydraulic oil. A remote control device for controlling the brake assembly must be prepared to operate the device. This completes the preparation work before blocking the car.
[0010] As a further technical solution of the present invention, the brake assembly includes a slider, which is movably engaged with a slide groove. A tactile switch located inside the slide groove is fixedly installed at the end of the slider away from the vertical rod, and a fixing frame is fixedly installed at the end of the slider near the track. The slider is made of cast iron.
[0011] As a further technical solution of the present invention, a limiting rod is movably sleeved inside the fixed frame. An electromagnet located inside the fixed frame is fixedly installed at one end of the limiting rod near the slider. A vehicle blocking block is fixedly installed at the other end of the limiting rod away from the fixed frame. A first limiting spring is movably sleeved on the outer side of the limiting rod. The left and right ends of the first limiting spring are respectively fixedly connected to one end of the fixed frame and one end of the vehicle blocking block.
[0012] When the mine car is about to approach the brake assembly, the electromagnet power is disconnected, the first limit spring is in its normal state, and the braking block protrudes from the track. As the mine car moves, the outer side of the mine car can contact the braking block. At this time, the mine car starts to brake. Due to inertia, the mine car continues to move and drives the brake assembly to continue to move forward. This causes the slider to move relative to the slide groove and moves the movable rod forward. At this time, the piston plate can move relative to the oil storage pipe, and the second limit spring is compressed. The hydraulic oil inside the oil storage pipe then enters the interior of the temporary storage tank through the output pipe to complete the hydraulic oil transfer and buffering process.
[0013] The braking system is designed to initially stop the mine car that needs to stop. It also utilizes the inertia of the mine car during braking to compress the second limit spring and dissipate its kinetic energy. At the same time, it moves the hydraulic oil located inside the oil storage pipe from the oil storage pipe to the storage tank, i.e., from a low position to a high position, to further buffer and absorb its braking kinetic energy and store energy for subsequent actions, thus completing the subsequent vehicle-stopping action.
[0014] As a further technical solution of the present invention, the end of the temporary storage tank near the vehicle blocking assembly is fixedly connected to a first connecting pipe, the end of the first connecting pipe away from the temporary storage tank is fixedly connected to a power tank, the bottom end of the power tank is connected to the outer side of the oil storage pipe, the end of the power tank away from the first connecting pipe is fixedly connected to a second connecting pipe, and the other end of the second connecting pipe is connected to the vehicle blocking assembly. Both the first connecting pipe and the second connecting pipe are rubber hoses.
[0015] The kinetic energy generated by braking causes the hydraulic oil inside the oil reservoir to flow further, pushing the hydraulic oil from the temporary storage tank into the first connecting pipe and then through the power tank before flowing into the car-stopping assembly through the second connecting pipe to complete the subsequent car-stopping action. All the power comes from the inertia generated when the mine car brakes.
[0016] As a further technical solution of the present invention, the vehicle blocking assembly includes a first movable seat, which is movably connected to the end of the vertical rod away from the fixed seat. A fixed tube is fixedly sleeved on the inner side of the first movable seat. A limit plug is movably sleeved inside the fixed tube. An extension rod located inside the fixed tube is fixedly installed at the top of the limit plug. The top of the extension rod passes through the top of the fixed tube and is fixedly installed with a second movable seat.
[0017] As a further technical solution of the present invention, the vehicle blocking assembly also includes a vehicle blocking frame located on the front of the vertical rod. The vehicle blocking frame has a rotating shaft at one end near the vertical rod. The vehicle blocking frame is rotatably connected to the vertical rod through the rotating shaft. The front of the vehicle blocking frame has a slot and is movably connected to a second movable seat through the slot. One end of the second movable seat can slide relative to the vehicle blocking frame.
[0018] As a further technical solution of the present invention, a third limiting spring is movably sleeved on the outer side of the extension rod. The upper and lower ends of the third limiting spring are respectively fixedly connected to the bottom end of the second movable seat and the top end of the fixed tube. An oil inlet located above the limiting plug is fixedly connected on the outer side of the fixed tube near the top end. The other end of the oil inlet is connected to the second connecting tube.
[0019] Hydraulic oil enters through the inlet via the second connecting pipe and applies downward pressure to the limiting plug. At this time, the extension rod and the limiting plug move downward, and the third limiting spring is compressed. As hydraulic oil continues to enter and the stop frame is connected to the second movable seat, the second movable seat is subjected to downward pressure, forcing the stop frame to be subjected to downward deflection force. At this time, the second movable seat can move in an arc relative to the stop frame and apply an inward pulling force to the stop frame. At this time, the stop frame can rotate relative to the pivot, and the fixed pipe rotates relative to the vertical rod through the first movable seat. The fixed pipe becomes inclined, and the stop frame rotates 90 degrees and becomes vertical. The two stop frames can block the mine car and prevent it from moving further.
[0020] By utilizing the inertia of the mine car during braking, the device buffers its kinetic energy while simultaneously transferring hydraulic oil. The pressure provided by the flowing hydraulic oil forces the two stop frames from a vertical to a parallel position, thus blocking the mine car. The entire process requires no additional power source. After the mine car moves to the corresponding position, the device gradually reduces its kinetic energy, bringing it to a slow stop. It then uses its kinetic energy to automatically stop the car after braking, avoiding the problems of traditional car-stopping devices that require external energy and manual control, as well as the risk of collisions between the mine car and the stop device. This device not only effectively prevents collisions but also automatically completes the car-stopping action without the need for other energy sources. Furthermore, the car-stopping action is relatively smooth, making it suitable for installation and use in mining areas.
[0021] After the mine car stops, and the construction workers observe that there are no potential dangers ahead, they can directly control the electromagnet power supply via remote control. The electromagnet generates magnetic force to attract the slider, simultaneously moving the limit rod and the car-stopping block towards the fixed frame. At this point, the first limit spring is compressed, and the car-stopping block moves away from the track, no longer obstructing the mine car. The entire device is no longer subjected to the pushing force of the mine car. The second limit spring automatically resets, moving the movable rod and piston plate backward. This causes the entire braking assembly to move backward, creating negative pressure inside the oil reservoir. Simultaneously, the third limit spring returns to its original deformation, the extension rod and the limit plug automatically move upward, the fixed pipe returns to a vertical position, and the car-stopping frame returns to its vertical position. In the straight state, when the car stop is closed and the limit plug moves upward, the hydraulic oil between the limit plug and the fixed pipe can be discharged through the oil inlet and further flow back to the storage tank through the second connecting pipe, the power tank, and the first connecting pipe. At this time, the hydraulic oil is subjected to the dual effects of gravity and negative pressure, causing the hydraulic oil to flow back to the inside of the oil storage pipe, and causing the brake assembly to move backward quickly to return to its initial position. At this time, the hydraulic oil also returns to its initial state, and the mine car can continue to move forward. When the slider moves to the rear end of the chute, the tactile switch contacts the chute. The tactile switch is activated to directly control the electromagnet power to turn off. At this time, the first limit spring, the limit rod, and the car stop block automatically reset to their initial state, thus blocking the subsequent mine cars.
[0022] By utilizing the kinetic energy generated by the inertia during the braking process of the mine car, the kinetic energy is converted and temporarily stored during the braking process. When it is necessary to release the car, simply turning on the power to the electromagnet releases the stored energy, quickly completing the reverse motion and closing the car. At the same time, it can automatically enter the pre-blocking state when the slider returns to the initial position. The whole process is automated and requires no additional energy assistance. This avoids the problem of traditional car blocking devices requiring manual opening and closing of the car blocking device. The entire device has a high degree of automation and is suitable for mass production.
[0023] As a further technical solution of the present invention, a main shaft is movably connected to the middle of the inner cavity of the power tank, and an impeller located inside the power tank is fixedly sleeved on the outer side of the main shaft. The cleaning component includes a mounting bracket, which is fixedly connected to the side of the power tank. An extension shaft is movably connected to the middle of the inner cavity of the mounting bracket. One end of the extension shaft passes through the mounting bracket and is connected to the main shaft. A fan located inside the mounting bracket is fixedly sleeved on the outer side of the extension shaft. Through slots are provided at equal angles on the back of the mounting bracket.
[0024] During the blocking process, hydraulic oil can enter the blocking assembly from the temporary storage tank through the power tank. At this time, the hydraulic oil flows from the first connecting pipe through the power tank into the second connecting pipe and impacts the impeller, causing the impeller to rotate. This drives the main shaft to rotate and further drives the fan to rotate. At this time, the reverse rotation generates negative pressure, which sucks out the dust near the track. Conversely, when the blocking is closed, the hydraulic oil flows back from the blocking assembly through the power tank to the temporary storage tank. That is, the hydraulic oil flows from the second connecting pipe through the power tank into the first connecting pipe. At this time, the impeller rotates in the forward direction, which further drives the fan to rotate in the forward direction, generating positive pressure and air force to clear debris near the track and prevent interference with the movement of the mine car.
[0025] By utilizing the inertia of the mine car during braking, hydraulic oil can be transported. During the braking and contact phases, the release of braking kinetic energy and stored energy causes the hydraulic oil to move in different directions, thereby achieving the reverse and forward rotation of the impeller, and ultimately the rotation of the fan. This generates corresponding negative and positive pressures to gently remove dust and foreign objects near the track, enhancing driving safety. The entire process requires no additional power assistance, reducing the number of inspections required by track safety personnel and improving safety, making it suitable for widespread use.
[0026] The beneficial effects of this invention are as follows:
[0027] 1. This invention utilizes the inertia of a mine car during braking to buffer its kinetic energy while simultaneously transferring hydraulic oil. The pressure provided by the flowing hydraulic oil forces two car-stopping frames to change from a vertical to a parallel state, thereby blocking the mine car. The entire process requires no additional power source. After the mine car moves to the corresponding position, the device gradually reduces its kinetic energy, bringing it to a slow stop. The device then uses its kinetic energy to automatically stop the car after braking. This avoids the problems of traditional car-stopping devices that require external energy and manual control, as well as the risk of collisions between the mine car and the car-stopping device. It not only effectively prevents collisions but also automatically completes the car-stopping action without the need for other energy sources. Furthermore, the car-stopping action is relatively smooth, making it suitable for installation and use in mining areas.
[0028] 2. This invention utilizes the kinetic energy generated by the inertia during the braking process of the mine car to convert and temporarily store the kinetic energy during the braking process. When it is necessary to release the car, simply turning on the power to the electromagnet releases the stored energy, quickly completing the reverse motion and closing the car. At the same time, it can automatically enter the pre-blocking state when the slider returns to the initial position. The entire process is automated and requires no additional energy assistance. It avoids the problem of traditional car blocking devices requiring manual opening and closing of the car blocking device. The entire device has a high degree of automation and is suitable for mass production.
[0029] 3. This invention utilizes the inertia of the mine car during braking to transport hydraulic oil. During vehicle braking and contact formation, the release of braking kinetic energy and stored energy causes the hydraulic oil to move in different directions, thereby achieving the reverse and forward rotation of the impeller, and ultimately the rotation of the fan. This generates corresponding negative and positive pressures to gently remove dust and foreign objects near the track, enhancing driving safety. The entire process requires no additional power assistance, reducing the number of inspections required by track safety personnel and improving safety, making it suitable for widespread use.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] like Figures 1 to 6 As shown in the embodiment of the present invention, a mine car blocking device includes a base 1, a track 2 laid at the center of the top of the base 1, and fixed seats 3 installed on the left and right sides of the top of the base 1 on both sides of the track 2. Each of the two fixed seats 3 has a sliding groove 4 at its relatively close end, and a brake assembly 5 is movably engaged inside the sliding groove 4. A vertical rod 6 is fixedly installed at the end of the fixed seat 3 away from the brake assembly 5, and a blocking assembly 19 is provided at the right end of the vertical rod 6. Each of the two fixed seats 3 has an oil storage pipe 9 at its right end, which is connected to the base 1 via a connecting seat. An output pipe 10 is fixedly connected to the end of the oil storage pipe 9 away from the fixed seat 3, and a temporary storage tank 11 is fixedly connected to the other end of the output pipe 10. 11 is fixedly connected to the base 1 via a connecting seat. A cleaning component 17 is provided between the brake assembly 19 and the temporary storage tank 11. A movable rod 7 located inside the slide groove 4 is fixedly installed at the end of the brake assembly 5 near the vertical rod 6. The end of the movable rod 7 away from the brake assembly 5 passes through one end of the fixed seat 3 and one end of the oil storage pipe 9 and is located inside the oil storage pipe 9. A piston plate 8 located inside the oil storage pipe 9 is fixedly installed at the end of the movable rod 7 away from the brake assembly 5. The piston plate 8 and the oil storage pipe 9 are movably sleeved together. A second limiting spring 18 is movably sleeved on the outer side of the movable rod 7. The left and right ends of the second limiting spring 18 are fixedly connected to one end of the inner cavity of the slide groove 4 and one end of the brake assembly 5, respectively.
[0042] Before using the device, the two sets of devices must be installed on the left and right sides of the base 1, that is, on the left and right sides of the track 2. The brake assembly 5 must be able to block the mine car according to the size of the mine car. At the same time, the oil storage pipe 9 must be filled with hydraulic oil. A remote control device for controlling the brake assembly 5 must be prepared to operate the device. This completes the preparation work before blocking the car.
[0043] like Figure 3 and Figure 4 as well as Figure 8 As shown, the brake assembly 5 includes a slider 501, which is movably engaged with the slide groove 4. A tactile switch 502 located inside the slide groove 4 is fixedly installed at the end of the slider 501 away from the vertical rod 6. A fixing frame 503 is fixedly installed at the end of the slider 501 near the track 2. The slider 501 is made of cast iron. A limit rod 505 is movably sleeved inside the fixing frame 503. An electromagnet 504 located inside the fixing frame 503 is fixedly installed at the end of the limit rod 505 near the slider 501. A vehicle stop block 506 is fixedly installed at the end of the limit rod 505 away from the fixing frame 503. A first limit spring 507 is movably sleeved on the outer side of the limit rod 505. The left and right ends of the first limit spring 507 are fixedly connected to one end of the fixing frame 503 and one end of the vehicle stop block 506, respectively.
[0044] When the mine car is about to approach the brake assembly 5, the power supply to the electromagnet 504 is disconnected, and the first limit spring 507 is in its normal state. At this time, the blocking block 506 protrudes from the track 2. As the mine car moves, the outer side of the mine car can contact the blocking block 506. At this time, the mine car starts to brake. Due to inertia, the mine car continues to move and drives the brake assembly 5 to continue to move forward. This will drive the slider 501 to move relative to the slide groove 4 and drive the movable rod 7 to move forward. At this time, the piston plate 8 can move relative to the oil storage pipe 9, and the second limit spring 18 is compressed. The hydraulic oil inside the oil storage pipe 9 then enters the interior of the temporary storage tank 11 through the output pipe 10 to complete the transfer and buffering process of the hydraulic oil.
[0045] The braking assembly 5 is used to initially block the mine car that needs to stop. The inertia of the mine car during braking is used to compress the second limit spring 18 to consume its kinetic energy. At the same time, the hydraulic oil located inside the oil storage pipe 9 is transported from the oil storage pipe 9 to the temporary storage tank 11, that is, from a low place to a high place, to further buffer and absorb its braking kinetic energy, store energy for subsequent actions, and complete the subsequent vehicle blocking action.
[0046] like Figure 3 and Figure 7As shown, the end of the temporary storage tank 11 near the barrier assembly 19 is fixedly connected to a first connecting pipe 12, and the end of the first connecting pipe 12 away from the temporary storage tank 11 is fixedly connected to a power tank 14. The bottom end of the power tank 14 is connected to the outer side of the oil storage pipe 9, and the end of the power tank 14 away from the first connecting pipe 12 is fixedly connected to a second connecting pipe 13. The other end of the second connecting pipe 13 is connected to the barrier assembly 19. Both the first connecting pipe 12 and the second connecting pipe 13 are rubber hoses.
[0047] The kinetic energy generated by braking causes the hydraulic oil inside the oil storage pipe 9 to flow further, pushing the hydraulic oil from the temporary storage tank 11 into the first connecting pipe 12 and then through the power tank 14 before flowing into the car blocking assembly 19 through the second connecting pipe 13 to complete the subsequent car blocking action. All the power comes from the inertia generated when the mine car brakes.
[0048] like Figure 1 and Figure 2 as well as Figure 3 and Figure 5 As shown, the barrier assembly 19 includes a first movable seat 191, which is movably connected to the end of the vertical rod 6 away from the fixed seat 3. A fixed tube 192 is fixedly sleeved on the inner side of the first movable seat 191. A limit plug 193 is movably sleeved inside the fixed tube 192. An extension rod 194 located inside the fixed tube 192 is fixedly installed at the top of the limit plug 193. The top of the extension rod 194 passes through the top of the fixed tube 192 and is fixedly installed with a second movable seat 196. The barrier assembly 19 also includes a barrier frame 198 located on the front of the vertical rod 6. A rotating shaft 197 is provided at the end of the barrier frame 198 near the vertical rod 6. 98 is rotatably connected to the vertical rod 6 via the pivot 197. The front of the stop frame 198 has a slot and is movably connected to the second movable seat 196 via the slot. One end of the second movable seat 196 can slide relative to the stop frame 198. The outer side of the extension rod 194 is movably sleeved with a third limiting spring 195. The upper and lower ends of the third limiting spring 195 are fixedly connected to the bottom end of the second movable seat 196 and the top end of the fixed tube 192, respectively. The outer side of the fixed tube 192 is fixedly connected to an oil inlet 199 located above the limiting plug 193 at a position near the top. The other end of the oil inlet 199 is connected to the second connecting tube 13.
[0049] First embodiment:
[0050] Hydraulic oil can enter through the second connecting pipe 13 from the oil inlet 199 and apply downward pressure to the limiting plug 193. At this time, the extension rod 194 and the limiting plug 193 move downward, and the third limiting spring 195 is compressed. As hydraulic oil continues to enter and the stop frame 198 is connected to the second movable seat 196, the second movable seat 196 is subjected to downward pressure, which forces the stop frame 198 to be subjected to downward deflection force. At this time, the second movable seat 196 can move in an arc relative to the stop frame 198 and apply an inward pulling force to the stop frame 198. At this time, the stop frame 198 can rotate relative to the rotating shaft 197. At the same time, the fixed pipe 192 rotates relative to the vertical rod 6 through the first movable seat 191. The fixed pipe 192 changes to an inclined state, while the stop frame 198 rotates ninety degrees and changes to a vertical state. The two stop frames 198 can block the mine car and prevent the mine car from moving further.
[0051] By utilizing the inertia of the mine car during braking, the hydraulic oil is transported while buffering its kinetic energy. The pressure provided by the flowing hydraulic oil forces the two stop frames 198 from a vertical to a parallel state, thereby blocking the mine car. The entire process requires no additional power source. After the mine car moves to the corresponding position, the device gradually reduces its kinetic energy, bringing it to a slow stop. The device then uses its kinetic energy to automatically stop the car after braking. This avoids the problems of traditional car-stopping devices that require external energy and manual control, as well as the problem of collisions between the mine car and the car-stopping device. It not only effectively prevents collisions but also automatically completes the car-stopping action without other energy sources. The car-stopping action is also relatively smooth, making it suitable for installation and use in mining areas.
[0052] Second embodiment:
[0053] After the mine car stops, and the construction personnel observe that there are no potential dangers ahead, the power to the electromagnet 504 can be directly turned on via remote control. The electromagnet 504 generates magnetic force to attract the slider 501, simultaneously moving the limit rod 505 and the car-stopping block 506 towards the fixed frame 503. At this time, the first limit spring 507 is compressed, and the car-stopping block 506 moves away from the track 2, no longer obstructing the mine car. The entire device is no longer subjected to the pushing force of the mine car. The second limit spring 18 automatically resets, causing the movable rod 7 and piston plate 8 to move backward. The brake assembly 5 moves backward, creating negative pressure inside the oil reservoir 9. Simultaneously, the third limit spring 195 restores its deformation extension rod 194 and the limit plug 193 automatically move upward, the fixed pipe 192 returns to its vertical position, and the car-stopping frame 198 returns to its normal position. When the car is in the vertical position and the car stop is closed, the hydraulic oil between the limit plug 193 and the fixed pipe 192 can be discharged through the oil inlet 199 when the limit plug 193 moves upward. It can then flow back to the storage tank 11 through the second connecting pipe 13, the power tank 14, and the first connecting pipe 12. At this time, the hydraulic oil is subjected to the dual effects of gravity and negative pressure, causing the hydraulic oil to flow back to the oil storage pipe 9. This causes the brake assembly 5 to move backward quickly and return to its initial position. The hydraulic oil also returns to its initial state, and the mine car can continue to move forward. When the slider 501 moves to the rear end of the chute 4, the tactile switch 502 contacts the chute 4. The tactile switch 502 activates and directly controls the electromagnet 504 to turn off the power. At this time, the first limit spring 507, the limit rod 505, and the car stop block 506 automatically reset to their initial state, thus blocking the subsequent mine cars.
[0054] By utilizing the kinetic energy generated by the inertia during the braking process of the mine car, the kinetic energy is converted and temporarily stored during the braking process. When it is necessary to release the car, simply turning on the power to the electromagnet 504 releases the stored energy, quickly completing the reverse motion and closing the car. At the same time, it can automatically enter the pre-blocking state when the slider 501 returns to the initial position. The whole process is automated and does not require additional energy assistance. This avoids the problem of traditional car blocking devices requiring manual opening and closing of the car blocking device. The entire device has a high degree of automation and is suitable for mass production.
[0055] like Figure 3 and Figure 7 as well as Figure 9As shown, a main shaft 16 is movably connected to the center of the inner cavity of the power tank 14. An impeller 15 located inside the power tank 14 is fixedly sleeved on the outer side of the main shaft 16. The cleaning component 17 includes a mounting bracket 171, which is fixedly connected to the side of the power tank 14. An extension shaft 174 is movably connected to the center of the inner cavity of the mounting bracket 171. One end of the extension shaft 174 passes through the mounting bracket 171 and is connected to the main shaft 16. A fan 173 located inside the mounting bracket 171 is fixedly sleeved on the outer side of the extension shaft 174. A through groove 172 is provided at equal angles on the back of the mounting bracket 171.
[0056] Third embodiment:
[0057] During the blocking process, hydraulic oil can enter the blocking assembly 19 from the temporary storage tank 11 through the power tank 14. At this time, the hydraulic oil flows from the first connecting pipe 12 through the power tank 14 into the second connecting pipe 13 and impacts the impeller 15, causing the impeller 15 to rotate. At the same time, it drives the main shaft 16 to rotate and further drives the fan 173 to rotate. At this time, its reverse rotation generates negative pressure to suck out the dust located near the track 2. Conversely, when the blocking is closed, the hydraulic oil flows back from the blocking assembly 19 through the power tank 14 to the temporary storage tank 11. That is, the hydraulic oil flows from the second connecting pipe 13 through the power tank 14 into the first connecting pipe 12. At this time, the impeller 15 rotates in the forward direction, further driving the fan 173 to rotate in the forward direction to generate positive pressure and wind force to clear the debris near the track 2 and prevent interference with the movement of the mine car.
[0058] By utilizing the inertia of the mine car during braking, the hydraulic oil can be transported. During the braking and contact phases, the release of braking kinetic energy and stored energy causes the hydraulic oil to move in different directions, thereby achieving the reverse and forward rotation of the impeller 15, and ultimately the rotation of the fan 173. This generates corresponding negative and positive pressures to gently remove dust and foreign objects near the track 2, enhancing driving safety. The entire process requires no additional power assistance, reducing the number of inspections by track safety personnel and improving safety, making it suitable for widespread use.
[0059] Working principle and usage process:
[0060] When the mine car is about to approach the brake assembly 5, the power supply to the electromagnet 504 is disconnected, the first limit spring 507 is in normal state, and the blocking block 506 protrudes from the track 2. As the mine car moves, the outer side of the mine car can contact the blocking block 506. At this time, the mine car starts to brake. Due to inertia, the mine car continues to move and drives the brake assembly 5 to continue to move forward. At this time, the slider 501 can move relative to the slide groove 4 and drive the movable rod 7 to move forward. At this time, the piston plate 8 can move relative to the oil storage pipe 9, and the second limit spring 18 is compressed. The hydraulic oil inside the oil storage pipe 9 then enters the interior of the temporary storage tank 11 through the output pipe 10 to complete the transfer and buffering process of the hydraulic oil.
[0061] Hydraulic oil can enter from the inlet 199 through the second connecting pipe 13 and apply downward pressure to the limiting plug 193. At this time, the extension rod 194 and the limiting plug 193 move down accordingly, and the third limiting spring 195 is compressed. As the hydraulic oil continues to enter and the stop frame 198 is connected to the second movable seat 196, the second movable seat 196 is subjected to downward pressure, which forces the stop frame 198 to be subjected to downward deflection force. At this time, the second movable seat 196 can move in an arc relative to the stop frame 198 and apply an inward pulling force to the stop frame 198. At this time, the stop frame 198 can rotate relative to the rotating shaft 197. At the same time, the fixed pipe 192 rotates relative to the vertical rod 6 through the first movable seat 191. The fixed pipe 192 changes to an inclined state, while the stop frame 198 rotates ninety degrees and changes to a vertical state. The two stop frames 198 can block the mine car and prevent the mine car from moving further.
[0062] After the mine car stops, and the construction personnel observe that there are no potential dangers ahead, the power to the electromagnet 504 can be directly turned on via remote control. The electromagnet 504 generates magnetic force to attract the slider 501, simultaneously moving the limit rod 505 and the car-stopping block 506 towards the fixed frame 503. At this time, the first limit spring 507 is compressed, and the car-stopping block 506 moves away from the track 2, no longer obstructing the mine car. The entire device is no longer subjected to the pushing force of the mine car. The second limit spring 18 automatically resets, causing the movable rod 7 and piston plate 8 to move backward. The brake assembly 5 moves backward, creating negative pressure inside the oil reservoir 9. Simultaneously, the third limit spring 195 restores its deformation extension rod 194 and the limit plug 193 automatically move upward, the fixed pipe 192 returns to its vertical position, and the car-stopping frame 198 returns to its normal position. When the car is in the vertical position and the car stop is closed, the hydraulic oil between the limit plug 193 and the fixed pipe 192 can be discharged through the oil inlet 199 when the limit plug 193 moves upward. It can then flow back to the storage tank 11 through the second connecting pipe 13, the power tank 14 and the first connecting pipe 12. At this time, the hydraulic oil is subjected to the dual effects of gravity and negative pressure, causing the hydraulic oil to flow back to the oil storage pipe 9. This causes the brake assembly 5 to move backward quickly and return to its initial position. At this time, the hydraulic oil also returns to its initial state, and the mine car can continue to move forward. When the slider 501 moves to the rear end of the chute 4, the tactile switch 502 contacts the chute 4. The tactile switch 502 is activated to directly control the electromagnet 504 to turn off the power. At this time, the first limit spring 507, the limit rod 505 and the car stop block 506 automatically reset to their initial state, thus blocking the subsequent mine cars.
[0063] During the blocking process, hydraulic oil can enter the blocking assembly 19 from the temporary storage tank 11 through the power tank 14. At this time, the hydraulic oil flows from the first connecting pipe 12 through the power tank 14 into the second connecting pipe 13 and impacts the impeller 15, causing the impeller 15 to rotate. At the same time, it drives the main shaft 16 to rotate and further drives the fan 173 to rotate. At this time, its reverse rotation generates negative pressure to suck out the dust located near the track 2. Conversely, when the blocking is closed, the hydraulic oil flows back from the blocking assembly 19 through the power tank 14 to the temporary storage tank 11. That is, the hydraulic oil flows from the second connecting pipe 13 through the power tank 14 into the first connecting pipe 12. At this time, the impeller 15 rotates in the forward direction, further driving the fan 173 to rotate in the forward direction to generate positive pressure and wind force to clear the debris near the track 2 and prevent interference with the movement of the mine car.
