Description

Technical Field

[0001] The present invention relates to the technical field of mine engineering, and particularly relates to an anti - runaway system applicable to inclined - shaft suspension bridges. Background Art

[0002] An inclined - shaft runaway refers to an accident in which, when hoisting or lowering vehicles in an inclined shaft, the hoisting wire rope or the mine - car connection device breaks, and the mine car runs out of control and falls along the inclined shaft. When an inclined - shaft runaway occurs, the out - of - control vehicle endangers personal safety, may damage the support and cause roof fall and rib spalling, and may also damage facilities such as cables, air and water pipelines, railways, and hoisting containers laid in the inclined shaft, resulting in the suspension of mine production. If the mine air contains flammable gases or substances, the sparks generated by the impact of the runaway car hitting or damaging electrical facilities may cause an explosion, resulting in more serious losses.

[0003] Currently, the devices for protecting against inclined - shaft runaways all brake and buffer by hitting and driving obstacles after the mine car runs away. However, the mine car itself does not participate in braking, so that when the mine car hits the obstacle, a huge impact force will be generated, which easily damages both the mine car itself and the obstacle. Moreover, when the mine car stops braking, it is easy for the mine car to lose its center of gravity and overturn, resulting in the mine car derailing from the track, which has certain dangers and causes greater losses. Summary of the Invention

[0004] Aiming at the disadvantages in the prior art that the mine car itself does not participate in braking, only relies on hitting and driving obstacles to brake and buffer, and the mine car is easy to derail and overturn when braking, the purpose of the present invention is to provide an anti - runaway system applicable to inclined - shaft suspension bridges, which can more effectively brake the mine car, is not easy to derail from the railway track, and can more fully limit the position of the vehicle body, making the vehicle body not easy to overturn.

[0005] The technical solution is as follows: An anti - runaway system applicable to inclined - shaft suspension bridges includes a mounting plate, a housing, a blocking and protecting component, and a wheel friction component. There are two railway tracks on the ground, and a mine car is placed between the two railway tracks. Two mounting plates are installed on the ground, and the two mounting plates are symmetrically arranged. A housing is fixedly connected between the two mounting plates. The blocking and protecting component is arranged on the mounting plate, and the blocking and protecting component is used to intercept and buffer the mine car. The wheel friction component is arranged on the railway track, and the wheel friction component is used to brake the mine car.

[0006] As an improvement of the above solution, the barrier component includes a protective cover, a movable body, a first buffer spring, a steel wire rope, a guide strip, a movable column, a sliding strip, an electric push rod, a movable block and a guardrail. The protective covers are fixedly connected to both of the mounting plates. The movable body is slidably connected to each of the protective covers. A plurality of first buffer springs are connected between the protective cover and the movable body. The guide strips are fixedly connected to both of the mounting plates. The movable columns are slidably connected to both of the guide strips. A plurality of steel wire ropes are connected between the movable column and the movable body. Two electric push rods are fixedly connected to the inner top of the housing. The two electric push rods are symmetrically arranged. The bottom ends of the telescopic rods of the two electric push rods are fixedly connected to the movable blocks. The guardrail is fixedly connected between the two sliding strips. The guardrail is slidably connected to the two movable blocks.

[0007] As an improvement of the above solution, the wheel friction component includes an L-shaped column, a limiting plate, an inclined panel, an inclined strip, a mounting frame, a guide groove plate, a clamping frame, a connecting rod, a pushing block, a friction block and a second buffer spring. Two L-shaped columns are fixedly connected to the bottom of the guardrail. The two L-shaped columns are symmetrically arranged. The limiting plates are fixedly connected to both of the mounting plates. The inclined panel is slidably connected to one end of the limiting plate close to the railway track. The inclined panel contacts the L-shaped column. The inclined strip is fixedly connected to the inclined panel. Four mounting frames are fixedly connected to the ore car. The guide groove plates are slidably connected to the four mounting frames. The clamping frames are fixedly connected to the four mounting frames. Two connecting rods are slidably connected to each of the guide groove plates. Each of the clamping frames is slidably connected to the two connecting rods on the same guide groove plate. The pushing blocks are fixedly connected to the ends of the two connecting rods away from the guide groove plates. The clamping frame is slidably connected to the pushing block. Two friction blocks are slidably connected to the clamping frame. The second buffer spring is connected between the pushing block and the friction block.

[0008] As an improvement of the above solution, the friction block has a rectangular structure.

[0009] As an improvement of the above solution, it further includes a track friction component. The track friction component is arranged on the connecting rod. The track friction component includes a second friction plate and a first friction plate. The second friction plates are fixedly connected to the two connecting rods away from the ore car. The first friction plates are fixedly connected to the two connecting rods close to the ore car.

[0010] As an improvement to the above solution, it further includes a vehicle body fixing component. The vehicle body fixing component is arranged on the mounting plate. The vehicle body fixing component includes a driving long rod, a support column, a limiting frame, a movable plate, a guiding groove block, and a connecting spring. Driving long rods are fixedly connected to both of the L-shaped columns. Support columns are fixedly connected to both of the mounting plates. A limiting frame is slidably connected to the support column. A movable plate is slidably connected to the support column. The guiding groove block is fixedly connected to the top of the movable plate. A guiding groove is formed in the guiding groove block. The end of the driving long rod away from the L-shaped column is located in the guiding groove on the guiding groove block. Three connecting springs are connected between the guiding groove block and the limiting frame.

[0011] As an improvement to the above solution, it further includes a fixing plate and an arc-shaped block. Fixing plates are fixedly connected to both of the second friction plates. Two arc-shaped blocks are fixedly connected to the fixing plates.

[0012] As an improvement to the above solution, the top of the arc-shaped block is provided with an arc surface.

[0013] As an improvement to the above solution, it further includes a cover plate. Cover plates are fixedly connected to the tops of both of the limiting frames. Both of the cover plates are located above the mine car.

[0014] As an improvement to the above solution, the cover plate has a rectangular structure.

[0015] The beneficial effects of the present invention are as follows:

[0016] When a mine car runs away, the mine car contacts the guardrail. The mine car will push the guardrail to move. The movement of the guardrail will drive the movable body to move away from the guiding strip through the steel wire rope. The first buffer spring will be stretched. The movement of the guardrail will also drive both of the L-shaped columns to move away from the protective cover, so that the pushing block drives the two friction blocks in the same clamping frame to move towards each other. The two friction blocks contact the wheels of the mine car, and the second buffer spring will be compressed, so that the mine car is decelerated and braked. In this way, the guardrail buffers the mine car when it is impacted, so as to achieve the effect of decelerating and stopping the mine car. And the friction plates can fully frictionally limit the wheels of the mine car, so as to effectively decelerate and brake the mine car, and further greatly reduce the impact force of the mine car on the guardrail and extend the service life of the guardrail.

[0017] When the two connecting rods move towards each other, the connecting rods will drive the second friction plate and the first friction plate to move towards each other. The second friction plate, the first friction plate contact the railway track. In this way, the closer the second friction plate, the first friction plate contact the railway track, the greater the frictional force between the second friction plate, the first friction plate and the railway track, so that the mine car can be more fully frictionally limited, and further achieve the effect of braking the mine car.

[0018] When the protective fence moves and drives both L-shaped columns to move away from the protective cover, the L-shaped columns will drive the driving long rod to move along the guiding groove on the guiding groove block towards the direction close to the protective fence, so that the guiding groove block drives the limiting frame to move towards the direction close to the mine car through the connecting spring. The limiting frame contacts the body of the mine car. In this way, the limiting frame can be in close contact with the body of the mine car, so that the friction between the limiting frame and the mine car increases. Furthermore, the risk that the mine car breaks away from the railway track when decelerating and braking can be greatly reduced, making the mine car brake more smoothly.

[0019] When the connecting rod drives the friction plate II and the friction plate I to move towards each other, the friction plate II will drive the fixing plate to move towards the direction close to the friction plate I. The movement of the fixing plate drives the two arc-shaped blocks on the same fixing plate to move towards the direction close to the friction plate I. The two arc-shaped blocks contact the wheels of the mine car. In this way, the arc-shaped blocks can further increase the friction force on the wheels of the mine car, so as to further limit the mine car more fully and further make the mine car brake more smoothly.

[0020] When the guiding groove block drives the limiting frame to move towards the direction close to the mine car through the connecting spring, the movement of the limiting frame will drive the cover plate to move towards the direction close to the mine car. The cover plate is located above the mine car. In this way, the cover plate can limit the mine car more fully, prevent the mine car from tipping over upwards when braking, and the cover plate can also prevent the items in the mine car from being easily thrown out during emergency braking, better protecting the items in the mine car.

[0042] Embodiment 1

[0043] An anti-runaway system applicable to inclined shaft suspension bridges, as Figures 1 - 19 shown, includes a mounting plate 111, a housing 112, a barrier component, and a wheel friction component. There are two railway tracks 102 provided on the ground 101, and a mine car 103 is placed between the two railway tracks 102. Two mounting plates 111 are bolted to the ground 101, and the two mounting plates 111 are symmetrically arranged. A housing 112 is bolted between the two mounting plates 111. The barrier component is arranged on the mounting plate 111 and is used to stop and buffer the mine car 103. It is arranged on the railway track 102, and the wheel friction component is used to frictionally limit the wheels of the mine car 103.

[0044] The barrier component includes a protective cover 21, a movable body 22, a first buffer spring 23, a steel wire rope 24, a guide bar 25, a movable column 26, a sliding bar 27, an electric push rod 201, a movable block 202, and a guardrail 203. Two protective covers 21 are bolted to the two mounting plates 111 respectively. Each protective cover 21 is slidably connected with a movable body 22. A number of first buffer springs 23 are connected between the protective cover 21 and the movable body 22 by hooks. Two guide bars 25 are riveted to the two mounting plates 111 respectively. A movable column 26 is slidably connected to each of the two guide bars 25. A number of steel wire ropes 24 are connected between the movable column 26 and the movable body 22. Two electric push rods 201 are bolted to the inner top of the housing 112, and the two electric push rods 201 are symmetrically arranged. The bottom ends of the telescopic rods of the two electric push rods 201 are bolted with a movable block 202. A guardrail 203 is riveted between the two sliding bars 27, and the guardrail 203 is slidably connected with the two movable blocks 202.

[0045] The wheel friction component includes an L-shaped column 31, a limiting plate 32, an inclined panel 33, an inclined strip 34, a mounting bracket 35, a guide groove plate 36, a clamping frame 37, a connecting rod 38, a pushing block 39, a friction block 310 and a second buffer spring. The bottom of the guardrail 203 is connected with two L-shaped columns 31 by rivets. The two L-shaped columns 31 are symmetrically arranged. The limiting plates 32 are connected to the two mounting plates 111 by bolts. One end of the limiting plate 32 close to the railway track 102 is slidably connected with the inclined panel 33. The inclined panel 33 contacts the L-shaped column 31. The inclined strip 34 is connected to the inclined panel 33 by rivets. Four mounting brackets 35 are connected to the ore car 103 by bolts. Four guide groove plates 36 are slidably connected to the four mounting brackets 35. Four clamping frames 37 are connected to the four mounting brackets 35 by bolts. Two connecting rods 38 are slidably connected to each guide groove plate 36. Each clamping frame 37 is slidably connected to the two connecting rods 38 on the same guide groove plate 36. One end of the two connecting rods 38 far from the guide groove plate 36 is connected with a pushing block 39 by rivets. The clamping frame 37 is slidably connected with the pushing block 39. Two friction blocks 310 are slidably connected in the clamping frame 37. The friction block 310 has a rectangular structure. A second buffer spring is connected between the pushing block 39 and the friction block 310 by a hook.

[0046] When the mine car 103 runs away, the mine car 103 contacts the guardrail 203. The mine car 103 will push the guardrail 203 to move. The movement of the guardrail 203 will drive the movable body 22 to move in the direction close to the guide strip 25 through the steel wire rope 24. The first buffer spring 23 will be stretched. The guardrail 203 will be disengaged from both electric push rods 201. The mine car 103 will be stopped by the guardrail 203. The first buffer spring 23 will reset. The reset of the first buffer spring 23 will drive the movable body 22 to reset in the direction away from the guide strip 25. The reset of the movable body 22 will drive the guardrail 203 to move and reset in the direction close to the protective cover 21 through the steel wire rope 24. The electric push rod 201 will contact the guardrail 203 again. The movement of the guardrail 203 will also drive both L-shaped columns 31 to move in the direction away from the protective cover 21. The L-shaped column 31 contacts the inclined surface strip 34. The movement of the L-shaped column 31 will drive the inclined surface strip 34 to move upward. The upward movement of the inclined surface strip 34 will drive the inclined panel 33 to move upward. The inclined panel 33 will contact the guide groove plate 36, so that the inclined panel 33 drives the guide groove plate 36 to move upward. The upward movement of the guide groove plate 36 will drive the two connecting rods 38 on the same guide groove plate 36 to move closer to each other. The connecting rod 38 will drive the two pushing blocks 39 in the same clamping frame 37 to move closer to each other, so that the pushing block 39 drives the two friction blocks 310 in the same clamping frame 37 to move closer to each other through the second buffer spring. The two friction blocks 310 contact the wheels of the mine car 103. The second buffer spring will be compressed. The closer the contact between the friction block 310 and the wheels of the mine car 103 is, the greater the friction force between the friction block 310 and the wheels of the mine car 103 will be, so that the mine car 103 decelerates and stops. After the mine car 103 stops, the reset of the guardrail 203 will drive both L-shaped columns 31 to move and reset in the direction close to the protective cover 21. The L-shaped column 31 is disengaged from the inclined surface strip 34. The inclined surface strip 34, the inclined panel 33 and the guide groove plate 36 move downward and reset under the action of gravity. The downward movement and reset of the guide groove plate 36 will drive the two connecting rods 38 on the same guide groove plate 36 to move away from each other. The reset of the connecting rod 38 will drive the two pushing blocks 39 in the same clamping frame 37 to reset in the direction away from each other. The second buffer spring will reset. The reset of the pushing block 39 drives the two friction blocks 310 in the same clamping frame 37 to reset in the direction away from each other. The friction block 310 is disengaged from the wheels of the mine car 103. Then the staff starts the electric push rod 201, so that the telescopic rod of the electric push rod 201 contracts. The contraction of the telescopic rod of the electric push rod 201 will drive the movable block 202 to move upward. The upward movement of the movable block 202 will drive the guardrail 203 to move upward. The upward movement of the guardrail 203 will drive the sliding strip 27 to move upward. Then the staff pushes the mine car 103 away. Finally, the staff adjusts the electric push rod 201, and the telescopic rod of the electric push rod 201 extends, so that the guardrail 203 moves downward and resets.In this way, the guardrail 203 buffers the mine car 103 when it is impacted, so as to slow down and stop the mine car 103. Moreover, the friction plate can fully frictionally limit the wheels of the mine car 103, so as to effectively decelerate and brake the mine car 103, thereby greatly reducing the impact force of the mine car 103 on the guardrail 203 and prolonging the service life of the guardrail 203.

[0047] Embodiment 2

[0048] Based on Embodiment 1, as Figures 12 - 13 shown, it further includes a track friction component. The track friction component is arranged on the connecting rod 38. The track friction component includes a second friction plate and a first friction plate 42. The second friction plates are connected to the two connecting rods 38 far from the mine car 103 by rivets, and the first friction plates 42 are connected to the two connecting rods 38 close to the mine car 103 by rivets.

[0049] When the two connecting rods 38 move towards each other, the movement of the connecting rods 38 will drive the second friction plate and the first friction plate 42 to move towards each other. The second friction plate, the first friction plate 42 contact the rail 102. After the mine car 103 stops braking, the connecting rods 38 will drive the second friction plate and the first friction plate 42 to move away from each other and reset, and the second friction plate, the first friction plate 42 are separated from the rail 102. In this way, the closer the second friction plate, the first friction plate 42 contact the rail 102, the greater the friction force between the second friction plate, the first friction plate 42 and the rail 102, so that the mine car 103 can be more fully frictionally limited, and thus the mine car 103 can be better braked.

[0050] Embodiment 3

[0051] Based on Embodiment 2, as Figures 3 - 16 shown, it further includes a vehicle body fixing component. The vehicle body fixing component is arranged on the mounting plate 111. The vehicle body fixing component includes a driving long rod 51, a support column 52, a limiting frame 53, a movable plate 54, a guide groove block 55 and a connecting spring 56. The driving long rods 51 are connected to the two L-shaped columns 31 by rivets, the support columns 52 are connected to the two mounting plates 111 by bolts. The limiting frame 53 is slidably connected to the support column 52, the movable plate 54 is slidably connected to the support column 52. The guide groove block 55 is connected to the top of the movable plate 54 by bolts. A guide groove is formed in the guide groove block 55. One end of the driving long rod 51 far from the L-shaped column 31 is located in the guide groove on the guide groove block 55. Three connecting springs 56 are connected between the guide groove block 55 and the limiting frame 53 by hooks.

[0052] When the movement of the guardrail 203 drives both L-shaped columns 31 to move away from the protective cover 21, the movement of the L-shaped columns 31 will drive the driving long rod 51 to move along the guiding groove on the guiding groove block 55 towards the protective cover 21. The movement of the driving long rod 51 will drive the guiding groove block 55 to move towards the ore car 103. The movement of the guiding groove block 55 will drive the movable plate 54 to move towards the ore car 103. The movement of the movable plate 54 will drive the guiding groove block 55 to move towards the ore car 103. The guiding groove block 55 drives the limiting frame 53 to move towards the ore car 103 through the connecting spring 56. The limiting frame 53 contacts the body of the ore car 103, and the connecting spring 56 will be compressed. After the ore car 103 is braked and stopped, the L-shaped column 31 will drive the driving long rod 51 to move along the guiding groove on the guiding groove block 55 away from the guardrail 203 for resetting. The connecting spring 56 resets, and the reset of the connecting spring 56 drives the limiting frame 53 to reset. The limiting frame 53 is disengaged from the body of the ore car 103. In this way, the limiting frame 53 can be in close contact with the body of the ore car 103, so that the friction force between the limiting frame 53 and the ore car 103 is increased. Furthermore, the risk that the ore car 103 breaks away from the railway track 102 when decelerating and braking can be greatly reduced, making the ore car 103 brake more smoothly.

[0053] Embodiment 4

[0054] On the basis of Embodiment 3, as Figures 12 - 13 shown, it further includes a fixing plate 61 and an arc-shaped block 62. The fixing plate 61 is connected to both of the second friction plates by bolts. Two arc-shaped blocks 62 are connected to the fixing plate 61 by rivets. The top of the arc-shaped block 62 is provided with an arc surface.

[0055] When the connecting rod 38 drives the second friction plate and the first friction plate 42 to move towards each other, the movement of the second friction plate will drive the fixing plate 61 to move towards the first friction plate 42. The movement of the fixing plate 61 drives the two arc-shaped blocks 62 on the same fixing plate 61 to move towards the first friction plate 42. The two arc-shaped blocks 62 contact the bottom of the wheels of the ore car 103. After the ore car 103 is braked and stopped, when the second friction plate resets, it will drive the fixing plate 61 to move away from the first friction plate 42. The movement of the fixing plate 61 drives the two arc-shaped blocks 62 on the same fixing plate 61 to move away from the first friction plate 42. The two arc-shaped blocks 62 are disengaged from the bottom of the wheels of the ore car 103. In this way, the friction force between the arc-shaped blocks 62 and the wheels of the ore car 103 can be further increased, so that the arc-shaped blocks 62 can more fully restrict the wheels of the ore car 103, and further make the ore car 103 brake more smoothly.

[0056] Embodiment 5

[0057] On the basis of Embodiment 4, as Figure 4 and Figure 15As shown, it further includes a cover plate 7. The tops of the two limiting frames 53 are both connected to the cover plate 7 by rivets. The two cover plates 7 are both located above the ore car 103, and the cover plate 7 has a rectangular structure.

[0058] When the guiding groove block 55 drives the limiting frame 53 to move towards the ore car 103 through the connecting spring 56, the movement of the limiting frame 53 will drive the cover plate 7 to move towards the ore car 103. Since the cover plate 7 is located above the ore car 103, after the ore car 103 stops braking, the limiting frame 53 will drive the cover plate 7 to move away from the ore car 103. In this way, the cover plate 7 can more fully limit the ore car 103, preventing the ore car 103 from tipping over upwards when braking, and the cover plate 7 can also prevent the items in the ore car 103 from being easily thrown out during sudden braking, better protecting the items in the ore car 103.
