Description

Technical Field

[0001] This utility model relates to the technical field of train pulling and moving devices, specifically a train pulling and moving device based on front and rear double-set support supports. Background Technology

[0002] In underground mining fields such as coal mines, cable trolleys are used for tunnel transportation. The normal operation of the cable trolleys relies on rails for movement, and electricity is used to power the trolley drive device. In actual operation, when the rail power supply system is not yet installed in the initial stage of newly built tunnels or during the maintenance of existing rail circuit failures, some rails cannot be energized. In addition, there are special areas in underground tunnels that require non-electrical operations, where the rails cannot be energized. In this case, auxiliary devices are needed to complete the cable trolley pulling operation. Existing auxiliary pulling devices require a lot of manual operation, resulting in low pulling efficiency and failing to meet the needs of rapid auxiliary passage of cable trolleys in non-electrical track scenarios.

[0003] Therefore, a train pulling device based on front and rear double-set support is proposed to solve the problems mentioned above. Utility Model Content

[0010] Preferably, the push rod is arranged along the track direction, and the telescopic ends of the first push cylinder and the second push cylinder are fixedly connected to the first slider. The first slider is slidably connected to the side of the base, and the surface of the push rod near the base is connected to the two first sliders respectively through connecting blocks.

[0011] Preferably, each of the two base sides is provided with a first sliding groove, and the push rod is slidably connected to the two base sides respectively through the first sliding groove, and the end of the push rod is connected to an anchor chain.

[0012] Preferably, the pulling assembly includes a first pulling cylinder, a second pulling cylinder, a pulling plate, a steel cable, a second inner clamping cylinder, a second outer clamping cylinder, and a first outer clamping cylinder.

[0015] Compared with the prior art, this utility model provides a train pulling device based on front and rear double-set support supports, which has the following beneficial effects: 1. By extending and retracting the support cylinder, after the top of the support cylinder contacts the top of the channel and presses it to tighten the tunnel roof, it works in conjunction with the pulling and moving components to realize the mechanized pulling and moving of the cable train in the scenario of no-electric track, thereby improving the pulling and moving efficiency and meeting the needs of cable train auxiliary passage in the scenario of no-electric track.

[0016] 2. The switching between support and sliding states is achieved through the sliding component. When the support cylinder is pressed against the top of the channel, the roller retracts into the housing, and the anti-slip bottom contacts the track. The anti-slip stripes enhance the friction between the base and the track. When the base needs to slide along the track, the double-headed hydraulic cylinder drives the lifting slider to move, so that the anti-slip bottom is removed from the track. The base contacts the track through the roller, reducing the sliding friction resistance and further improving the stability and efficiency of the cable trolley under the non-electric track.

[0017] 3. One set of mechanisms uses a support cylinder to press against the fixed base at the top of the channel, while the sliding component of another set of mechanisms raises the base so that the rollers contact the track to reduce resistance. The first or second push cylinder extends to drive the push rod and anchor chain to pull the cable train, while simultaneously driving the other set of mechanisms to move synchronously. Through the cyclical operation mode of one set of mechanisms supporting and pulling, and the other set of mechanisms following and sliding, the cable train can be continuously and quickly moved away from the working surface.

[0018] 4. By laying pull plates along the track, the pull assembly can be pulled along the direction of the pull plates, allowing the pull assembly to be used on non-linear tracks, thus expanding the applicability of the device and improving its practicality and versatility.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figure 1 - Figure 11 This embodiment of a train pulling device based on front and rear double-set support includes a first mechanism 1, a second mechanism 2, and a track 3. Both the first mechanism 1 and the second mechanism 2 include a base 4, a sliding component 5, and a support component 6. The lower surface of the base 4 is slidably connected to the track 3. The first mechanism 1 and the second mechanism 2 are arranged sequentially along the track 3. The first mechanism 1 and the second mechanism 2 form a double support structure through the base 4, the sliding component 5, and the support component 6. Combined with the pulling component 7, alternating displacement can be achieved. The sliding component 5 is located inside the base 4 and includes a roller 501, a lifting slider 502, a double-headed hydraulic cylinder 503, a swing arm 504, an auxiliary pulley 505, and a housing 506. The sliding component 5 is used to support the base 4.

[0023] An anti-slip base 8 is fixedly connected to one side of the housing 506 near the track 3. Both the bottom surface of the housing 506 and the anti-slip base 8 have openings for telescopic rollers 501. The rollers 501 and auxiliary pulleys 505 are rotatably connected to both ends of the swing arm 504. The swing arm 504 is rotatably connected to the inner side of the housing 506 via a shaft. The bottom surface of the housing 506 and the anti-slip base 8 have openings for telescopic rollers 501. The anti-slip base 8 has anti-slip stripes. When the anti-slip base 8 contacts the track 3, the anti-slip stripes can increase the friction between the two and prevent the base 4 from sliding when supported. The openings provide a channel for the extension and retraction of the rollers 501. The rollers 501 and auxiliary pulleys 505 are rotatably connected to both ends of the swing arm 504. The swing arm 504 is rotatably connected to the inner side of the housing 506 via a shaft. The swing arm 504 can rotate around the shaft, thereby driving the rollers 501 and auxiliary pulleys 505 at both ends to achieve position linkage.

[0024] The fixed section of the double-headed hydraulic cylinder 503 is fixedly installed on the inner bottom surface of the housing 506. The two telescopic ends of the double-headed hydraulic cylinder 503 are respectively fixedly connected to a lifting slider 502. The side of the lifting slider 502 near the auxiliary pulley 505 is arc-shaped. The end of the lifting slider 502 near the auxiliary pulley 505 is inserted into the bottom of the auxiliary pulley 505. The double-headed hydraulic cylinder 503 can drive the two lifting sliders 502 to move at the same time. The arc-shaped surface design allows the lifting slider 502 to smoothly insert into the bottom of the auxiliary pulley 505 and complete the lifting action.

[0025] A support assembly 6 is located on the upper surface of the base 4. The support assembly 6 includes a support cylinder 601, a swing cylinder 602, a fixed support 603, a rotating support 604, and a support block 605. The support assembly 6 is used to fix mechanism 1 and mechanism 2. A pulling assembly 7 is provided on the side of the base 4 of both mechanism 1 and mechanism 2. The base 4 provides basic support for mechanism 1 and mechanism 2. The lower end of the fixed support 603 is fixedly connected to the base 4, and the upper end of the fixed support 603 is rotatably connected to the rotating support 604. The lower end of the support cylinder 601 is rotatably connected to the base 4 via the rotating support 604, and the upper end of the support cylinder 601 is rotatably connected to the support block 605. The bottom end of the swing cylinder 602 is rotatably connected to the upper surface of the base 4, and the telescopic end of the swing cylinder 602 is rotatably connected to the upper end of the rotating support 604. The rotating support 604 can drive the support... Cylinder 601 rotates around fixed support 603. After the support cylinder 601 rotates to the target angle, the mechanical protective pin is inserted between fixed support 603 and rotating support 604 to lock the position of support cylinder 601. Swing cylinder 602 is a hydraulic cylinder powered by long-distance fluid supply from the fully mechanized mining system. Swing cylinder 602 is used to drive support cylinder 601 to rotate. After rotating to the correct position, the mechanical protective pin is inserted, and then support cylinder 601 is activated to tighten the top surface of the channel. The surface of support block 605 near the top of the channel is arc-shaped. Support block 605 is made entirely of metal. Anti-slip rubber is bonded to the contact surface between support block 605 and the top of the channel to prevent relative sliding between support block 605 and the top of the channel. Support cylinder 601 can apply extrusion force to the top of the channel through extension and retraction to form stable support. The arc-shaped support block 605 adapts to the arc-shaped contour of the top of the channel, and the metal material ensures structural strength. Please see Figure 1 - Figure 4 as well as Figure 9 , 10 11, The pulling assembly 7 includes a first outer clamping cylinder 70711, a second pushing cylinder 7020, a pushing rod 7030, and an anchor chain 7040. The fixed end of the first outer clamping cylinder 70711 is fixedly connected to the side of the base 4 of the first mechanism 1. The second pushing cylinder 7020 is fixedly connected to the side of the base 4 of the second mechanism 2. The pushing rod 7030 is arranged along the direction of the track 3. The telescopic ends of the first outer clamping cylinder 70711 and the second pushing cylinder 7020 are both fixedly connected to a first slider 10. The first slider 10 is slidably connected to the side of the base 4. The surface of the pushing rod 7030 near the base 4 is connected to the two first sliders 10 respectively through the connecting block 11. The sides of the two bases 4 are provided with a first sliding groove 12. The pushing rod 7030 is slidably connected to the sides of the two bases 4 respectively through the first sliding groove 12. The end of the pushing rod 7030 is connected to the anchor chain 7040, and the other end of the anchor chain 7040 is connected to the cable trolley.

[0026] The No. 1 outer clamping cylinder 70711, the No. 2 pushing cylinder 7020, and the support cylinder 601 are all hydraulic cylinders. A long-distance hydraulic supply pipeline is installed within the fully mechanized mining face. This long-distance hydraulic supply serves as the power source for the self-moving mechanism. In the supported state, when the support cylinder 601 is pressed against the top of the channel, the roller 501 retracts inside the housing 506. At this time, the anti-slip base 8 is in direct contact with the track 3. The anti-slip stripes enhance friction, ensuring the stability of the base 4. When the base 4 needs to slide along the track 3, the double-headed hydraulic cylinder is activated. The pressure cylinder 503, a double-headed hydraulic cylinder 503, extends, driving the arc-shaped surface of the lifting slider 502 to insert into the bottom of the auxiliary pulley 505 and lift the auxiliary pulley 505. When the auxiliary pulley 505 rises, it drives the swing arm 504 to rotate along the axis, thereby causing the roller 501 to move downward. At the same time, it lifts the base 4 by a small distance, so that the protective base does not contact the upper surface of the track 3. The base 4 contacts the upper surface of the base 4 through the roller 501. The contact between the roller 501 and the track 3 can greatly reduce the sliding friction resistance.

[0027] The swing cylinder 602 drives the rotating support 604 to rotate via telescopic drive, which in turn drives the support cylinder 601 to adjust its angle. When not in use, the mechanical protective pin is removed, and then the swing cylinder 602 drives the support cylinder 601 to rotate downwards, reducing the overall height of the equipment and allowing it to pass smoothly through narrow tunnel spaces. This reduces space restrictions during transport and improves the equipment's practicality in tunnel operations. When mechanized pulling of the cable trolley under the non-electric track 3 is required, the support cylinder 601 is activated first. When the top of the support cylinder 601 contacts the top of the tunnel and is pressurized to over 25MPa, the top of the support cylinder 601 presses firmly against the tunnel roof. The support cylinder 601 forms a stable support with the top of the channel through the support block 605 and squeezes the base 4, increasing the friction between the base 4 and the track 3 to prevent the base 4 from shifting during the pulling process. Then, the first outer clamping cylinder 70711 is activated. The first outer clamping cylinder 70711 extends and drives the push rod 7030 to move along the track 3 through the first slider 10. The end of the push rod 7030 is connected to the anchor chain 7040, and the other end of the anchor chain 7040 is connected to the cable trolley. When the push rod 7030 moves, it will drive the cable trolley to move synchronously along the track 3 through the anchor chain 7040, thereby realizing the mechanized pulling of the cable trolley in the scenario of no-electric track 3. Furthermore, the two support mechanisms cooperate to pull the cable trolley along the track 3 in the tunnel. When the first mechanism 1 pulls the cable trolley, the sliding component 5 of the second mechanism 2 lifts the base 4 of the second mechanism 2 by a small distance, so that the base 4 contacts the upper surface of the track 3 through the roller 501, thereby greatly reducing the sliding friction resistance. The telescopic end of the second push cylinder 7020 is fixedly connected to the push rod 7030. When the second push cylinder 7020 is locked, the push rod 7030 pulls the second mechanism 2 and the trolley to move synchronously through the second push cylinder 7020.

[0028] The specific alternating displacement process is as follows: Mechanism 1 provides support and drives Mechanism 2 to move forward: The top of the support cylinder 601 of Mechanism 1 is pressed against the top of the roadway. The roller 501 of Mechanism 1 is located inside the base 4. The base 4 of Mechanism 1 is in contact with the track 3 through the anti-slip bottom 8. At this time, the support cylinder 601 of Mechanism 2 is in a shortened state. Mechanism 2 is in contact with the track 3 through the roller 501. After the support cylinder 601 of Mechanism 1 is pressed, the outer clamping cylinder 70711 is activated, which drives the push rod 7030 to move. The push rod 7030 drives the base 4 of Mechanism 2 to slide along the track 3. At the same time, the end of the push rod 7030 is connected to the train car through the anchor chain 7040. When the push rod 7030 moves, it drives the train car to move.

[0029] Mechanism 2 provides support, and Mechanism 2 drives Mechanism 1 to move forward: The support cylinder 601 of Mechanism 2 is pressed against the top of the roadway, and the roller 501 is retracted into the base 4. After Mechanism 2 is pressed, the support cylinder 601 of Mechanism 1 retracts, and the roller 501 is pushed out of the base 4 by the double-headed hydraulic cylinder 503, so that the base 4 of Mechanism 1 contacts the track 3 through the roller 501. Then the first outer clamping cylinder 70711 retracts. After the first outer clamping cylinder 70711 of Mechanism 1 retracts, the second pushing cylinder 7020 of Mechanism 2 is activated, which drives the pushing rod 7030 to move. The pushing rod 7030 drives the cable car and Mechanism 1 to move. Through multiple cycles, the cable car is taken away from the working surface. Through the synergistic effect of the sliding component 5 and the double support mechanism, the stability and efficiency of the cable car pulling under the non-electric track 3 are improved. The working principle of the above embodiment is as follows: In the sliding assembly 5, the double-headed hydraulic cylinder 503 can simultaneously drive the two lifting sliders 502 to move. The arc surface of the lifting slider 502 is inserted into the bottom of the auxiliary pulley 505 and lifts the auxiliary pulley 505, which drives the swing arm 504 to rotate around the axis, thereby driving the rollers 501 at both ends to achieve position linkage with the auxiliary pulley 505, so that the base 4 contacts the track 3 through the anti-slip bottom 8 in the support state, and the friction is enhanced by the anti-slip stripes. In the sliding state, the rollers 501 contact the track 3. The contact between the rollers 501 and the track 3 can greatly reduce the sliding friction resistance. In the support assembly 6, the swing cylinder 602 is a hydraulic cylinder powered by the long-distance hydraulic supply from the fully mechanized mining system. The swing cylinder 602 is used to drive the support cylinder 601 to rotate, which in turn drives the rotating support 604 to rotate around the fixed support 603, thereby adjusting the angle of the support cylinder 601. The mechanical protection pin is inserted between the fixed support 603 and the rotating support 604 after the support cylinder 601 rotates to the target angle, locking the position of the support cylinder 601. The extension and retraction of the support cylinder 601 causes the support block 605 to contact the top of the channel. The anti-slip rubber is used to prevent relative sliding between the support block 605 and the top of the channel, and is pressurized to more than 25MPa to form a stable support. The pull-and-shift assembly 7 works alternately with mechanism 1 and mechanism 2. One set of mechanisms fixes the base 4 through the support assembly 6, while the other set of mechanisms reduces frictional resistance by making the roller 501 contact the track 3 through the sliding assembly 5. The pull-and-shift assembly 7 drives the cable trolley and the other set of mechanisms to move along the track 3 to achieve alternating displacement. Example

[0030] Please see Figure 5 - Figure 8 as well as Figure 9 , 10 11, The pulling assembly 7 includes a first pulling cylinder 7011, a second pulling cylinder 7021, a pulling plate 7031, a steel cable 7041, a second inner clamping cylinder 7051, a second outer clamping cylinder 7061, and a first outer clamping cylinder 7071. The fixed end of the first pulling cylinder 7011 is fixedly connected to the side of the base 4 of the first mechanism 1. The fixed end of the second pulling cylinder 7021 is fixedly connected to the side of the base 4 of the second mechanism 2. Second sliders 13 are slidably connected to the sides of the bases 4 of both the first mechanism 1 and the second mechanism 2. The first pulling cylinder 7011 and the second pulling cylinder 7021 are slidably connected to their corresponding second sliders 13. The second inner clamping cylinder 7051, the second outer clamping cylinder 7061, and the first outer clamping cylinder 7071 are all located inside the second slider 13. The first outer clamping cylinder 7071... The fixed end of 1 is fixedly connected to the inner top surface of the second slider 13 of the first mechanism 1. The second inner clamping cylinder 7051 and the second outer clamping cylinder 7061 are fixedly connected to the inner top surface of the second slider 13 of the second mechanism 2. The telescopic ends of the second inner clamping cylinder 7051, the second outer clamping cylinder 7061 and the first outer clamping cylinder 7071 are all fixedly connected to clamping plates 14. The side of the base 4 is fixedly connected to a wire tube 15. The two ends of the base 4 are provided with guide wheels 16. One end of the steel cable 7041 is inserted into the first mechanism 1 and fixedly connected to the second slider 13. The pull plate 7031 is set along the direction of the track 3. The pull rod is fixedly connected to the track 3. The steel cable 7041 passes through the bottom of the second inner clamping cylinder 7051 and passes through the guide tube and the guide wheel 16. The other end of the steel cable 7041 is connected to the cable trolley.

[0031] The pull plate 7031 is laid along the track 3. It can be pulled along the track 3 at the arc track 3. The pull plate 7031 needs to be laid in advance. The distance between the two pull plates 7031 is greater than the width of the trolley. In the supported state, the support cylinder 601 is pressed against the top of the channel, and the roller 501 is retracted inside the housing 506. At this time, the anti-slip bottom 8 is in direct contact with the track 3. The anti-slip stripes enhance the friction and ensure the stability of the base 4. When the base 4 needs to slide along the track 3, the double-headed hydraulic cylinder 503 is activated so that the protective bottom does not contact the upper surface of the track 3. The base 4 contacts the upper surface of the base 4 through the roller 501. The contact between the roller 501 and the track 3 can greatly reduce the sliding friction resistance. When the first outer clamping cylinder 7071 is pressed down, the first outer clamping cylinder 7071 clamps the inner bottom surface of the second slider 13 to the pull plate 7031. When the first pull cylinder 7011 retracts, it drives the first mechanism 1 to move forward. When the second outer clamping cylinder 7061 is pressed down, the second outer clamping cylinder 7061 clamps the inner bottom surface of the second slider 13 to the pull plate 7031. At this time, the second inner clamping cylinder 7051 is in the rising position. When the second pull cylinder 7021 retracts, it drives the second mechanism 2 to move forward. Mechanism 1 drives the cable trolley and Mechanism 2 to move. The specific implementation method is as follows: The top of the support cylinder 601 of mechanism 1 is pressed against the top of the roadway. The roller 501 of mechanism 1 is located inside the base 4. The base 4 of mechanism 1 is in contact with the track 3 through the anti-slip bottom 8. At this time, the support cylinder 601 of mechanism 2 is in the shortened state. Mechanism 2 is in contact with the track 3 through the roller 501. After the support cylinder 601 of mechanism 1 is pressed, the first pulling cylinder 7011 is activated. The first pulling cylinder 7011 drives the second slider 13 to move. The second slider 13 is fixedly connected to the steel cable 7041. The other end of the steel cable 7041 is connected to the cable trolley. When the second slider 13 moves, it pulls the cable trolley to move through the steel cable 7041, realizing the mechanized pulling of the cable trolley under the non-electric track 3. At the same time, the pulling plate 7031 is laid along the track 3, which can be used for pulling at the arc track 3, expanding the applicable range of the device. When mechanism 1 pulls the cable trolley, the inner clamping cylinder 7051 connected to mechanism 2 drives the clamping plate 14 to press down. The inner bottom surface of slider 13 and the lower surface of clamping plate 14 are rough surfaces. Clamping plate 14 and inner bottom surface of slider 13 clamp the steel cable 7041. At the same time, the sliding component 5 of mechanism 2 lifts the base 4 of mechanism 2 by a small distance, so that the base 4 contacts the upper surface of track 3 through roller 501, thereby greatly reducing sliding friction resistance. While mechanism 1 pulls the cable trolley, it drives mechanism 2 to move forward. After mechanism 1 drives the cable trolley and mechanism 2 to move, mechanism 2 provides support. Mechanism 2 drives the cable trolley to move. The specific implementation method is as follows: The support cylinder 601 of mechanism 2 is pressed against the top of the roadway and the roller 501 is retracted into the base 4. After mechanism 2 is pressed, the support cylinder 601 of mechanism 1 retracts and the roller 501 is pushed out of the base 4 by the double-headed hydraulic cylinder 503, so that the base 4 of mechanism 1 contacts the track 3 through the roller 501. Then, the outer clamping cylinder 7071 of mechanism 1 clamps the inner bottom surface of the sliding plate 7031 of slider 13 of mechanism 2. When the sliding cylinder 7011 of mechanism 1 retracts, it drives mechanism 1 of mechanism 1 to move forward. Then, the sliding cylinder 7021 of mechanism 2 extends and pulls the steel cable 7041, and the steel cable 7041 pulls the trolley forward.

[0032] Then, mechanism 1 moves forward via the pull plate 7031. Specifically, the outer clamping cylinder 7071 rises, then the pull cylinder 7011 extends. After the pull rod extends, the outer clamping cylinder 7071 presses down. The outer clamping cylinder 7071 clamps the inner bottom surface of the slider 13 with the pull plate 7031. When the pull cylinder 7011 retracts, it drives mechanism 1 to move forward. Then, mechanism 1 continues to drive the cable trolley and mechanism 2 to move. Through multiple cycles, the cable trolley is taken away from the working surface.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
