Description

Technical Field

[0001] This invention relates to the field of mine car slewing technology, specifically to a mine shaft shunting hydraulic slewing linkage device. Background Technology

[0002] A mine shaft shunting hydraulic switch machine is a key electromechanical-hydraulic integrated device installed in the coal mine or mine shaft area. It uses hydraulic power to drive the switch points or pusher mechanism to achieve precise scheduling, alignment, and marshalling of mine cars on the track. Its widespread application stems from the high frequency, high precision, and high safety requirements of shaft shunting operations, as well as the challenges of operating in harsh environments. Existing mine cars have gradually shifted from wire rope-pulled winches to electrically driven mine cars. However, because the slope at the mine shaft is much steeper than that of the tunnels inside the mine, fully loaded electric mine cars often struggle to leave the mine due to their own weight. A wire rope traction system is used at the mine shaft to assist in traction of the electric mine cars, preventing wheel slippage or center of gravity shift, which could cause the mine cars to tip over and create unnecessary safety hazards.

[0003] The existing technology has the following problems:

[0004] 1. In the use of existing mine shaft head shunting linkage devices, due to the long distance required for track changing at the mine shaft head, not only is the initial laying cost high, but also the daily manual adjustment, inspection and maintenance of the track are required.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 15As shown in the embodiment of the present invention, the hydraulic shunting linkage device for mine shafts includes a shunting body 1 and hydraulic cylinders 2. The bottom of the shunting body 1 is fixedly connected to the output ends of multiple hydraulic cylinders 2 arranged side by side. Fixed components are provided at both ends of the inner cavity of the shunting body 1. Several load-bearing I-beams 3 are slidably connected to the bottom of the shunting body 1. One end of the load-bearing I-beam 3 is fixedly connected to the end of the hydraulic cylinder 2 away from the output end through a connecting rod. Guide rails 4 are installed at both ends of the top of the shunting body 1. Several load-bearing I-beams 3 are slidably connected to the top of the guide rails 4. The mine car 5 has a clamping assembly at its bottom. The fixing assembly includes a linkage box 6 fixedly connected to both ends of the inner cavity of the rotating body 1. A fixing frame 7 is fixedly connected to the center of the inner wall of the linkage box 6. A linkage plate 8 is rotatably connected to the center of the inner wall of the fixing frame 7. Arc-shaped rods 9 are rotatably connected to both ends of the inner wall of the linkage plate 8. A multi-section linkage frame 10 is rotatably connected to one end of each arc-shaped rod 9. A fixing plate 11 is fixedly connected to one end of each multi-section linkage frame 10. One side of the outer wall of the fixing plate 11 contacts the bottom of the outer wall of the mine car 5. The top of the linkage box 6 is fixedly connected to... A reset spring frame 12 is rotatably connected to the inner cavity of a fixed plate 11 at the center of its outer wall. A hydraulic telescopic rod 13 is fixedly connected to one end of the inner cavity of a linkage box 6. A push plate 14 is rotatably connected to the output end of the hydraulic telescopic rod 13. One end of the push plate 14 is rotatably connected to the end of the inner wall of a linkage plate 8 away from the arc-shaped rod 9. The clamping assembly includes clamping boxes 15 fixedly connected to both ends of the bottom of a mine car 5. A bonding plate 16 is fixedly connected to the inner wall of the clamping box 15. A clamping plate 17 is rotatably connected to the inner wall of the bonding plate 16. The bonding plate 16 and the clamping plate 17 are connected to each other. A steel wire rope 18 is clamped between 7. A push plate 19 is fixedly connected to one side of the outer wall of the clamping plate 17. A guide plate 20 is fixedly connected to the side of the outer wall of the clamping plate 17 away from the push plate 19. A limit post 21 is fixedly connected to one end of the inner cavity of the guide plate 20. A limit frame 22 is slidably connected to both ends of the outer wall of the limit post 21. One side of the outer wall of the limit frame 22 is fixedly connected to one side of the top of the inner wall of the clamping box 15. A first return spring 23 is fixedly connected to the center of the top side of the limit frame 22. One end of the first return spring 23 is fixedly connected to the center of the bottom of the guide plate 20.

[0038] During operation, a load-bearing I-beam 3 is laid at the corner of the mine tunnel, and grease is applied to the top of the load-bearing I-beam 3. The rotating body 1 is placed on top of the load-bearing I-beam 3, and then the hydraulic cylinder 2 is placed on one side of the load-bearing I-beam 3. The output end of the hydraulic cylinder 2 is connected to the rotating body 1. At this time, the guide rail 4 is placed at both ends of the top of the rotating body 1, so that the guide rail 4 is aligned with the conveying rail. Then, two hydraulic lifting platforms 24 (here, the hydraulic lifting platform 24 is the prior art) equipped with the first adjusting box 26 are installed at both ends of the outermost load-bearing I-beam 3, and the two hydraulic lifting platforms 24 are respectively positioned between the conveying rail and the changing rail. One side of the outer wall of the hydraulic lifting platform 24 is in contact with the outermost load-bearing I-beam 3. Then, the load-bearing I-beam 3 at the end away from the hydraulic lifting platform 24 is... A blocking baffle 25 is installed on one side of beam 3. Then, the steel wire rope 18 is sequentially passed through the first push tooth plate 32 set on the inner wall of the first adjusting box 26, the second push tooth plate 53 set on the inner wall of the second adjusting box 34 in the inner cavity of the blocking baffle 25, the mounting box 35 set on the outer wall of the blocking baffle 25 away from the side of the load-bearing I-beam 3, and wound around the inner wall of the circular guide plate 39. After passing through the outer wall of the mounting box 35 away from the blocking baffle 25, it is wound around the surface of the winch 43 set at one end of the outer wall of the mounting box 35. Then, it passes through one end of the inner cavity of the mounting box 35 again and through one end of the inner cavity of the blocking baffle 25. Then, several mine cars 5 are placed on the conveying track, and the motor 42 is started so that the winch 43 drives the steel wire rope 18 wound on the surface to pull the several mine cars 5 towards the guide track 4.

[0039] It should be further explained that when the mine car 5 moves along the conveying track towards the guide track 4, the hydraulic lifting platform 24 is activated, and the height of the first adjusting box 26 at the output end is adjusted so that the first pushing tooth plate 32 on the inner wall of the first adjusting box 26 is parallel to the second pushing tooth plate 53 on the inner wall of the second adjusting box 34, and the steel wire rope 18 in its inner cavity is horizontal. Since clamping boxes 15 are provided at both ends of the bottom of the mine car 5, the inner wall of the clamping box 15 is provided with a fitting plate 16, and the outer wall of the fitting plate 16 is provided with a clamping plate 17, the fitting plate 16 and the clamping plate 17 clamp the outer wall of the steel wire rope 18. When the mine car 5 approaches the first adjusting box 26 with the traction of the steel wire rope 18, the fixed end of the first pushing tooth plate 32 protrudes from the first adjusting box 26. The top of the first pushing tooth plate 32 is streamlined and has a smooth surface. The mine car 5 travels to When guiding the surface of the track 4, the bottom of the bonding plate 16 and the clamping plate 17 are brought into contact with the extended end of the first push tooth plate 32. Since both ends of the outer wall of the bonding plate 16 and the clamping plate 17 have inward grooves, under the push of the inertia of the mine car 5, the inward grooves of the bonding plate 16 and the clamping plate 17 are brought into contact with the arc-shaped surface of the first push tooth plate 32, thereby opening the clamping plate 17 and allowing the bonding plate 16 and the opened clamping plate 17 to pass through the outer wall of the first push tooth plate 32 and continue to move on the surface of the guide track 4. When the first push tooth plate 32 is separated from the inner wall of the bonding plate 16 and the clamping plate 17, a limiting frame 22 is set on one side of the top of the inner wall of the clamping box 15, and the first return spring 23 set at the center of the top side of the limiting frame 22 is used to push the guide plate 20 set on one side of the outer wall of the clamping plate 17, so that the clamping plate 17 is reset and the wire rope 18 is clamped again.

[0040] It needs to be reiterated that when several mine cars 5 are stationary on the guide rail 4, linkage boxes 6 are installed at both ends of the inner cavity of the main body 1. Activating the hydraulic telescopic rod 13 at one end of the inner cavity of the linkage box 6 pushes the pusher plate 14 at its output end, causing the pusher plate 14 to push one end of the inner wall of the linkage plate 8. Since a fixed frame 7 is installed at the center of the inner wall of the linkage box 6, and the center of the inner wall of the fixed frame 7 supports the center of the linkage plate 8, the linkage plate 8 rotates around the fixed frame 7 under the push of the pusher plate 14. Since arc-shaped rods 9 are installed on both sides of the inner wall of the linkage plate 8, and one end of each arc-shaped rod 9 has multiple linkage frames 10, when the linkage plate 8 rotates, the arc-shaped rods 9 push the multiple linkage frames 10, causing the multiple linkage frames to rotate. The moving frame 10 pushes the fixed plate 11 and rotates around the reset spring frame 12 set at both ends of the top of the linkage box 6, fixing the mine car 5 placed on the guide rail 4. After the mine car 5 travels out of the mine, it needs to change tracks and move to the designated position to unload ore. At this time, the hydraulic cylinder 2 is activated, and the hydraulic cylinder 2 drives the rotating body 1, the guide rail 4 and the mine car 5 placed on it to shift laterally, so that the guide rail 4 moves away from the conveying rail and fits with the changing track, thereby completing the turning of the mine car 5. This further solves the problem that the traditional mine shaft shunting rotating linkage device requires a long track changing distance at the mine shaft, resulting in a large initial laying cost, and requires daily manual adjustment, inspection and maintenance of the track.

[0041] At the bottom of the main body 1, the outermost two load-bearing I-beams 3 are respectively attached to the outer walls of two hydraulic lifting platforms 24 and sealing baffles 25.

The two sides of the outer wall of the second transmission gear 52 are rotatably connected to the inner wall of the second adjusting box 34. A second push tooth plate 53 is engaged on the side of the outer wall of the second transmission gear 52 away from the second moving block 49. The side of the outer wall of the second push tooth plate 53 away from the second transmission gear 52 is slidably connected to the inner wall of the second adjusting box 34. The top of the inner cavity of the second push tooth plate 53 is... The second pusher plate 53 is slidably connected to the outer wall of the wire rope 18. The bottom of the second pusher plate 53 is fixedly connected to the third return spring 54. The bottom of the third return spring 54 is fixedly connected to the inner wall of the second adjustment box 34 at the end away from the second electric telescopic rod 48. The outer wall of the sealing baffle 25 is fixedly connected to the side away from the load-bearing I-beam 3. The center of the bottom of the inner wall of the installation box 35 is fixedly connected to the limit box 36. The center of the inner wall of the limit box 36 is fixedly connected to the partition 37. The two ends of the inner wall of the limit box 36 at the outer wall of the partition 37 are fixedly connected to the bidirectional electric telescopic rod 38.

The inner wall of the circular guide plate 39 is located between the sealing rod 40 and the rotating shaft 41 and is slidably connected to the wire rope 18. One end of the outer wall of the wire rope 18 passes through one end of the inner cavity of the sealing baffle 25. Motors 42 are fixedly connected to both ends of the outer wall of the mounting box 35 on the side away from the sealing baffle 25. The output ends of the motors 42 are fixedly connected to winches 43. The outer wall of the winches 43 is connected to the outer wall of the mounting box 35.

[0042] During operation, a blocking baffle 25 is installed on the outermost load-bearing I-beam 3 at the bottom of the main body 1, and a second adjusting box 34 is installed at both ends of the inner cavity of the blocking baffle 25. Two hydraulic lifting platforms 24 are respectively installed on the outer wall of the load-bearing I-beam 3 on the side of the bottom of the main body 1 away from the blocking baffle 25, so that the two hydraulic lifting platforms 24 are respectively positioned between the conveying track and the changing track. When the mine car 5 moves towards the guide track 4 on the conveying track under the traction of the wire rope 18, the first... The first push tooth plate 32, which is set on the inner wall of the adjustment box 26, drives the wire rope 18 and extends out of the first adjustment box 26, and collides with the bonding plate 16 and clamping plate 17 set at the bottom of the mine car 5. Since the bonding plate 16 and clamping plate 17 are provided with inward grooves on both sides of the outer wall, the extended end of the first push tooth plate 32 is streamlined and has a smooth surface, so that the first push tooth plate 32 opens the clamping plate 17 and slides in the inner wall of the clamping plate 17 and the bonding plate 16.When the mine car 5 moves onto the guide rail 4, several extension plates 44 are provided at one end of the top of the rotor body 1. Each extension plate 44 has a groove 45 on its top. An extension rod 46 is placed on the inner wall of the groove 45, and slots 47 are provided at both ends of the outer wall of the extension rod 46. This simultaneously activates the first electric telescopic rod 27 and the second electric telescopic rod 48 located at one end of the inner cavity of the first adjustment box 26 and the second adjustment box 34. Their output ends drive the first moving block 28 and the second moving block 49 respectively in the first adjustment box 26 and the second adjustment box 34. As the first moving block 28 and the second moving block 49 move upwards within the adjustment box 34, the outer walls of both the first moving block 28 and the second moving block 49 are provided with first tooth marks 30 and second tooth marks 51, and the inner walls of both the first adjustment box 26 and the second adjustment box 34 are provided with first transmission gears 31 and second transmission gears 52. Thus, as the first moving block 28 and the second moving block 49 move continuously, the first transmission gears 31 and 52 respectively drive the first pusher plate 32 and the second pusher plate 53, located on the side away from the first tooth marks 30 and second tooth marks 51, in the adjustment box 26. 6. The first moving block 28 and the second moving block 49 move downwards into the second adjusting box 34. At the same time, since the top of the outer wall of the first moving block 28 and the second moving block 49 are respectively provided with the first push rod 29 and the second push rod 50, as the first moving block 28 and the second moving block 49 move upwards, one end of the outer wall of the first push rod 29 and the second push rod 50 are pushed into the slots 47 provided at both ends of the outer wall of the extension rod 46, and the extension rod 46 is driven to disengage from the groove 45. Since the side of the outer wall of the clamping plate 17 away from the guide plate 20 is provided with the push plate 19, the extension rod 46 disengages from the groove 45. The rod 46 moves upward continuously, pushing one end of the bottom of the push plate 19 upward, causing the push plate 19 to drive the clamping plate 17 and the guide plate 20 to rotate. Since a limit post 21 is provided at one end of the inner cavity of the guide plate 20, the rotating guide plate 20 moves within the groove of the limit frame 22 using the limit post 21, thereby causing the wire rope 18 to disengage from the clamping plate 17 and the contact plate 16. Simultaneously, the first push tooth plate 32 and the second push tooth plate 53 move downward within the first adjustment box 26 and the second adjustment box 34 respectively, causing the wire rope 18 to fall onto the rotating body 1.

[0043] It should be further explained that at this time, the first electric telescopic rod 27 and the second electric telescopic rod 48 provided on the inner walls of the first adjusting box 26 and the second adjusting box 34 are retracted, and the internal parts of the first adjusting box 26 and the second adjusting box 34 are operated in the opposite way. This causes the first push tooth plate 32 and the second push tooth plate 53 to drive the wire rope 18 to rise again, and causes the first push rod 29 and the second push rod 50 to drive the extension rod 46 to move downward and release the restriction on the push plate 19. Since the first return spring 23 is provided at the center of one side of the top of the limit frame 22, the first return spring is used to... 23. Push the guide plate 20 to reset the clamping plate 17 and the push plate 19. At this time, start the hydraulic lifting platform 24 to lower the first adjustment box 26 as a whole. A height difference is generated between the first adjustment box 26 and the second adjustment box 34, so that the wire rope 18 cannot return to the bonding plate 16 and the clamping plate 17. The continuously descending first push rod 29 and second push rod 50 drive the extension rod 46 back into the groove 45 set at the top of the extension plate 44, and make the first push rod 29 and second push rod 50 disengage from the slots 47 set at both ends of the outer wall of the extension rod 46, thus completing the reset of the extension rod 46.

[0044] It needs to be reiterated that an installation box 35 is installed on the side of the outer wall of the sealing baffle 25 away from the load-bearing I-beam 3, and a limiting box 36 is installed on the inner wall of the installation box 35. A partition 37 is installed at the center of the inner wall of the limiting box 36. Bidirectional electric telescopic rods 38 (which are existing technologies) are installed at both the upper and lower ends of the outer wall of the partition 37. Since one end of the wire rope 18 is located in the inner wall of the circular guide plate 39, and a pivot 41 is installed at the center of the inner wall of the circular guide plate 39, while a sealing rod 40 is installed at the end away from the pivot 41, the wire rope 18 is restricted between the sealing rod 40 and the pivot 41. When the bidirectional electric telescopic rod 38 drives the circular guide plate 39 to slide within the partition 37 and the installation box 35, the installation box 35 is in the installation position. The wire rope 18 inside box 35 becomes loose due to the loss of support from the circular guide plate 39. At the same time, the hydraulic cylinder 2 is activated, driving the rotating body 1, guide rail 4, and mine car 5 to move on the load-bearing I-beam 3. As the guide rail 4 moves, the wire rope 18 comes into contact with one side of the inner wall of the guide rail 4. Simultaneously, the first adjusting box 26 and the second adjusting box 34 located on the side of the track changer are activated (the internal structure of the first adjusting box 26 and the second adjusting box 34 located on the side of the track changer is exactly the same as that of the first adjusting box 26 and the second adjusting box 34 located on the side of the conveying track). The above operation is repeated, causing the first pushing tooth plate 32 and the second pushing tooth plate 53 to push another wire rope 18 towards the bottom of the contact plate 16 and the clamping plate 17. During this period, the hydraulic lifting platform 24 located on one side of the track changer is activated, keeping the wire rope 18 between the first adjusting box 26 and the second adjusting box 34 horizontal. Simultaneously, the bidirectional electric telescopic rod 38 inside the mounting box 35, near the track changer, uses a circular guide plate 39 to push the wire rope 18, taut it to generate rigidity. Due to the inclined angle at the notch at the bottom of the bonding plate 16 and the clamping plate 17, the wire rope 18, pushed by the first pushing tooth plate 32 and the second pushing tooth plate 53, is squeezed between the bonding plate 16 and the clamping plate 17. By setting a second return spring 33 and a third return spring 54 at the bottom of the first pushing tooth plate 32 and the second pushing tooth plate 53, the first pushing tooth plate 32 and the second pushing tooth plate 53 rise. The rigid force is transformed into elastic force, avoiding excessive resistance to the first push tooth plate 32 and the second push tooth plate 53 during the upward movement, which would cause wear on the tooth marks between the first push tooth plate 32 and the second push tooth plate 53 and the first transmission gear 31 and the second transmission gear 52. If the wire rope 18 still cannot squeeze between the bonding plate 16 and the clamping plate 17, the motor 42 on the outer wall of the mounting box 35 near the side of the track changer is started. The motor 42 drives the corresponding winch 43 to move the wire rope 18 slowly, reducing the static friction between the wire rope 18, the bonding plate 16 and the clamping plate 17, and continuously changing the force point of the wire rope 18, so that the wire rope 18 can smoothly enter between the bonding plate 16 and the clamping plate 17, thereby completing the track change of the mine car 5.

[0045] Working principle:

[0046] like Figures 1-15As shown, a load-bearing I-beam 3 is laid at the corner of the mine tunnel, and grease is applied to the load-bearing I-beam 3. Then, the main body 1 of the slewing machine is placed on the load-bearing I-beam 3, and then the hydraulic cylinder 2 is placed on one side of the load-bearing I-beam 3, so that the end of one side of the load-bearing I-beam 3 is fixedly connected to the end of the hydraulic cylinder 2 away from the output end by a connecting rod. At the same time, the output end of the hydraulic cylinder 2 is connected to the main body 1 of the slewing machine. At this time, the guide rail 4 is placed at both ends of the top of the main body 1 of the slewing machine, so that the guide rail 4 is aligned with the conveying rail. Then, two hydraulic lifting platforms 24, each equipped with a first adjusting box 26, are respectively installed at both ends of the outermost load-bearing I-beam 3, so that the two hydraulic lifting platforms 24 are respectively positioned between the conveying rail and the changing rail, and one side of the outer wall of the hydraulic lifting platform 24 is connected to the outermost load-bearing I-beam 3. After the I-beam 3 is fitted together, a sealing baffle 25 is installed on the side of the load-bearing I-beam 3 away from the hydraulic lifting platform 24. The wire rope 18 is then passed sequentially through the first push tooth plate 32 on the inner wall of the first adjusting box 26, the second push tooth plate 53 on the inner wall of the second adjusting box 34 in the cavity of the sealing baffle 25, the mounting box 35 on the outer wall of the sealing baffle 25 away from the load-bearing I-beam 3, and wound around the inner wall of the circular guide plate 39. After passing through the outer wall of the mounting box 35 away from the sealing baffle 25, it is wound around the surface of the winch 43 at one end of the outer wall of the mounting box 35. Then, it passes through one end of the cavity of the mounting box 35 again and through one end of the cavity of the sealing baffle 25. Finally, the mine car 5 is placed on the conveying track, and the motor 42 is started to drive the winch 43. The steel wire rope 18 wound on the surface pulls the mine car 5, moving it towards the guide rail 4. Linkage boxes 6 are installed at both ends of the inner cavity of the rotating body 1. A hydraulic telescopic rod 13 installed at one end of the inner cavity of the linkage box 6 is activated. The hydraulic telescopic rod 13 pushes a pusher plate 14 at its output end, causing the pusher plate 14 to push one end of the inner wall of the linkage plate 8. Since a fixed frame 7 is installed at the center of the inner wall of the linkage box 6, and the center of the inner wall of the fixed frame 7 supports the center of the linkage plate 8, the linkage plate 8 rotates around the fixed frame 7 under the push of the pusher plate 14. Arc-shaped rods 9 are installed on both sides of the inner wall of the linkage plate 8, and multiple linkage frames 10 are installed at one end of each arc-shaped rod 9. When the linkage plate 8 rotates, the arc-shaped rods 9 push the multiple linkage frames 10, resulting in multi-section linkage. The frame 10 pushes the fixed plate 11 and rotates around the reset spring frame 12 set at both ends of the top of the linkage box 6, fixing the mine car 5 placed on the guide rail 4. After the mine car 5 travels out of the mine, it needs to change tracks and move to the designated position to unload the ore. At this time, the hydraulic cylinder 2 is activated, and the hydraulic cylinder 2 drives the main body 1 of the slewing mechanism, the guide rail 4 and the mine car 5 placed on its surface to shift laterally, so that the guide rail 4 moves away from the conveying rail and fits with the changing track, thereby completing the turning of the mine car 5. This further solves the problem that in the process of using the traditional mine shaft slewing linkage device, the distance required for track changing at the mine shaft is long, which not only leads to a large initial laying cost, but also requires daily manual adjustment of the track, as well as inspection and maintenance of the track.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
