Description

Technical Field

[0001] This invention relates to the field of anti-derailment technology for coal transport vehicles, specifically an anti-derailment buffer structure for automatically driven coal transport vehicles. Background Technology

[0002] Specialized vehicles for mine rail transport are designed to adapt to the narrow conditions of underground roadways. They are compact in size and include freight cars, personnel cars, and material cars. Mine cars are narrow-gauge railway transport vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches. Mine cars are classified into five main categories according to their structure and unloading method: fixed mine cars, tipper mine cars, single-sided curved rail side-discharge mine cars, bottom-discharge mine cars, and shuttle mine cars.

[0003] In the current use of coal transport vehicles, the tracks are often built on construction sites, which can lead to unevenness and problems such as falling rocks and protruding debris. This can cause severe vibrations during transport or cause the cargo to shift, altering the vehicle's center of gravity and leading to derailment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an anti-derailment buffer structure for autonomous coal transport vehicles. This structure solves the problem that, since tracks are often built on construction sites, they can be curved and uneven, and the track surface is prone to falling rocks and protruding debris. These issues can cause severe vibrations in the coal transport vehicle during transport, or the cargo shifts and changes the vehicle's center of gravity, leading to derailment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-derailment buffer structure for an automated coal transport vehicle, comprising: a side-discharge coal transport vehicle and a box-type carrier for fixing the coal transport vehicle, and a drive wheel for movement. The bottom of the box-type carrier is provided with a balancing mechanism, which includes a movable base. A drive motor is fixed to the outside of the movable base. An installation groove is provided inside the movable base. A threaded rod is rotatably installed in the installation groove, and the end of the threaded rod is fixedly connected to the output shaft of the drive motor. A counterweight is threadedly installed on the outer surface of the threaded rod, and the counterweight is slidably disposed in the installation groove.

[0006] The bottom of the movable base is provided with a buffer mechanism, which includes a sliding frame fixed to the bottom of the movable base. A wheel frame is fitted inside the sliding frame and is connected to the drive wheel. Multiple spring buffers are fixed inside the wheel frame. The other end of the spring buffer is fixedly installed on the movable base, and a sensor is fixed at the bottom of the movable base at the position of the wheel frame.

[0007] By adopting the above technical solution: the spring buffer buffers the wheel frame and drive wheel to prevent the impact of broken materials or protruding sections on the track on the coal car. During transportation, when the coal car tilts due to gravity, the moving base and sliding frame move downward under force, causing the wheel frame to contact the sensor. The sensor is electrically connected to the drive motor through an externally installed controller, which controls the drive motor to rotate the threaded rod. The rotation of the threaded rod drives the counterweight to move, adjusting the position of the counterweight to ensure the stability of the coal car itself.

[0008] Preferably, the housing carrier is provided with a cleaning mechanism, which includes a connecting roller, two forward guide rollers are rotatably mounted on the connecting roller, and pusher plates are fixedly mounted at both ends of the connecting roller. The pusher block is in contact with the side wall of the track and the side of the pusher block is provided with an inclined surface for guiding the material.

[0009] Preferably, the bottom of the housing base is provided with a locking assembly for locking and positioning the drive wheel. The locking assembly includes a locking plate, the outer surface of the drive wheel shaft is provided with a clamping element that cooperates with the locking plate, and the connecting roller is provided with a driving assembly for driving the locking plate to move.

[0010] Preferably, the clamping element includes a gear fixed to the surface of the axle of the drive wheel, and the clamping locking plate is provided with a groove for cooperating with the gear.

[0011] Preferably, the drive assembly includes multiple outer frames fixedly mounted on the connecting rollers, an inner rod slidably disposed within the outer frame, a limit guide rod fixedly disposed at the top of the inner rod, a support limit plate fixedly disposed at the bottom of the housing base, the limit guide rod slidably disposed on the support limit plate and the end of the limit guide rod being fixedly connected to the clamping locking plate.

[0012] Preferably, the outer surface of the limiting guide rod is fitted with an adaptive spring, and the two ends of the adaptive spring are respectively fixedly installed on the inner rod and the supporting limiting plate.

[0013] Preferably, the box carrier is provided with a track correction mechanism on both sides. The track correction mechanism includes a number of reset frames corresponding to the number of drive wheels. The reset frames are located on the side of the drive wheels and have guide ramps for guiding the drive wheels. A support rod is installed on the reset frame and a connecting block is fixed on the outer surface of the support rod. The same sliding rod is fixedly installed between two connecting blocks on the same side. Two inclined strip slides are opened on the box carrier, and the two sliding rods are slidably arranged in the two strip slides respectively.

[0014] Preferably, the tops of the two support rods on the same side are fixed with the same connecting plate, and the two sides of the housing base are fixed with support plates. Multiple elastic expansion joints are installed on the support plates, and the connecting plate is fixedly connected to the output end of the elastic connector on the same side.

[0015] Preferably, a sliding block is fixed to the surface of the movable base, and the sliding block is slidably disposed in a sliding groove opened at the bottom of the box carrier.

[0016] Preferably, the sliding block is configured as an inverted trapezoid, and the sliding groove is configured as an inverted trapezoidal groove that cooperates with the sliding block.

[0017] This invention provides an anti-derailment buffer structure for an automated coal transport vehicle. It has the following beneficial effects:

[0018] 1. This invention comprises a movable base, a drive motor, a threaded rod, a counterweight, a sliding frame, a wheel frame, a spring buffer, and a sensor. The spring buffer cushions the wheel frame and drive wheels, preventing the coal car from tilting and swaying due to impacts from debris or protruding sections on the track, which could lead to derailment of the drive wheels. Simultaneously, during transport, when the coal car tilts due to gravity, the movable base and sliding frame move downwards, causing the wheel frame to contact the sensor. The sensor, electrically connected to the drive motor via an externally mounted controller, activates the drive motor, causing the threaded rod to rotate. This rotation of the threaded rod moves the counterweight, adjusting its position to ensure the stability of the coal car.

[0019] 2. This invention, by setting up a locking plate, a locking component, and a drive assembly, addresses the issue of the forward guide roller jamming when a problem occurs with the track. The drive assembly drives the locking plate to move along with the locking component, bringing the locking plate closer to and into contact with it, thereby locking the locking component and locking the drive wheel. This forcibly stops the drive wheel from moving, facilitating on-site handling by personnel.

[0020] 3. This invention features an outer frame, an inner rod, a limiting guide rod, and a supporting limiting plate. The supporting limiting plate also includes a switch for controlling the drive mechanism of the drive wheel. When the locking plate engages with the gear, the inner rod moves to contact the switch, shutting down the drive mechanism that powers the drive wheel. The supporting limiting plate guides the limiting guide rod. When the forward guide roller is jammed, the outer frame and inner rod drive the limiting guide rod towards the drive wheel, causing the locking plate to move synchronously. This allows the locking plate to engage with the gear, achieving a locking and clamping operation and preventing the drive wheel from continuing to move and causing the coal car to overturn.

[0021] 4. This invention, by setting up a reset frame, support rod, connecting block, and sliding rod, allows the drive block to fall onto the reset frame when the drive wheel derails, driving the reset frame downwards until it contacts the ground. During the downward movement of the reset frame, the support rod moves downwards synchronously, and the support rod, through the connecting block, drives the sliding rod downwards. The sliding rod slides within the strip track, causing it to move towards the drive wheel and move in the opposite direction to the drive wheel. Simultaneously, under the action of the guide slope on the surface of the reset frame, the drive wheel will move back onto the track, automatically correcting the derailment and achieving reset.

[0031] The technical solution of the present invention will now be clearly and completely described 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.

[0032] Example 1

[0033] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 7 and attached Figure 8 This invention provides an anti-derailment buffer structure for an automated coal transport vehicle, comprising: a side-discharge coal transport vehicle 1 and a box-type carrier 2 for fixing the coal transport vehicle 1, and a drive wheel 4 for movement. The bottom of the box-type carrier 2 is provided with a balancing mechanism 3, which includes a movable base 301. A drive motor 305 is fixed to the outside of the movable base 301. An installation groove is provided inside the movable base 301. A threaded rod 304 is rotatably installed in the installation groove, and the end of the threaded rod 304 is fixedly connected to the output shaft of the drive motor 305. A counterweight 303 is threadedly installed on the outer surface of the threaded rod 304, and the counterweight 303 is slidably disposed in the installation groove.

[0034] The bottom of the movable base 301 is provided with a buffer mechanism 7. The buffer mechanism 7 includes a sliding frame 704 fixed to the bottom of the movable base 301. A wheel frame 701 is fitted inside the sliding frame 704 and is connected to the drive wheel 4. Multiple spring buffers 703 are fixed inside the wheel frame 701. The other end of the spring buffer 703 is fixedly installed on the movable base 301. A sensor 702 is fixed at the bottom of the movable base 301 at the position of the wheel frame 701.

[0035] By configuring a movable base 301, a drive motor 305, a threaded rod 304, a counterweight 303, a sliding frame 704, a wheel frame 701, a spring buffer 703, and a sensor 702, the spring buffer 703 can buffer the wheel frame 701 and the drive wheel 4, preventing the coal car 1 from tilting and swaying due to the impact of debris or protruding sections on the track, thus preventing the drive wheel 4 from derailing. Simultaneously, during transportation, when the coal car 1 tilts due to gravity, the movable base 301 and the sliding frame 704 move downwards under force, causing the wheel frame 701 to contact the sensor 702. The sensor 702 is electrically connected to the drive motor 305 via an externally installed controller, controlling the drive motor 305 to rotate the threaded rod 304. The rotation of the threaded rod 304 drives the counterweight 303 to move, adjusting its position to ensure the stability of the coal car.

[0036] For details, please refer to the appendix. Figure 1 -Appendix Figure 4 and attached Figure 6 The housing carrier 2 is equipped with a cleaning mechanism 5, which includes a connecting roller 510. Two forward guide rollers 506 are rotatably mounted on the connecting roller 510, and pusher plates 508 are fixedly mounted on both ends of the connecting roller 510. The pusher blocks are in contact with the side wall of the track, and the sides of the pusher blocks are provided with inclined surfaces for guiding materials. By setting up the connecting roller 510, forward guide rollers 506 and pusher plates 508, the forward guide rollers 506 move on the track to detect whether there are problems such as collapse or breakage of the track. The pusher blocks are used to break up and clean up the garbage on both sides of the track. When the connecting roller 510 drives the pusher plates 508 to move synchronously, the inclined surfaces on the pusher blocks enable the garbage fragments to move automatically to both sides to avoid affecting the subsequent work.

[0037] For details, please refer to the appendix. Figure 3 -Appendix Figure 6 The bottom of the housing base 2 is provided with a locking assembly for locking and positioning the drive wheel 4. The locking assembly includes a clamping plate 503. The outer surface of the drive wheel 4 shaft is provided with a clamping part that cooperates with the clamping plate 503. The connecting roller 510 is provided with a drive assembly for driving the clamping plate 503 to move.

[0038] By setting up a locking plate 503, a locking component, and a drive assembly, when a problem occurs with the track, the forward guide roller 506 may jam. The drive assembly drives the locking plate 503 to move along with it, causing the locking plate 503 to move closer to the locking component and make contact with it, thereby locking the locking component and locking the drive wheel 4. This forcibly stops the drive wheel 4 from moving, making it easier for staff to go to the site for handling.

[0039] For details, please refer to the appendix. Figure 4 and attached Figure 6 The clamping component includes a gear 509 fixed to the surface of the axle of the drive wheel 4, and the clamping locking plate 503 is provided with a groove that cooperates with the gear 509.

[0040] By setting gear 509, the slot on the locking plate 503 meshes with gear 509, which can effectively lock gear 509 and drive wheel 4, effectively avoid slippage and improve the locking effect.

[0041] For details, please refer to the appendix. Figure 3 -Appendix Figure 6The drive assembly includes multiple outer frames 505 fixedly mounted on the connecting rollers 510. An inner rod 507 is slidably provided inside the outer frame 505. A limit guide rod 502 is fixedly fixed at the top of the inner rod 507. A support limit plate 501 is fixedly fixed at the bottom of the box carrier 2. The limit guide rod 502 is slidably disposed on the support limit plate 501 and the end of the limit guide rod 502 is fixedly connected to the locking plate 503.

[0042] By setting up an outer frame 505, an inner rod 507, a limiting guide rod 502, and a supporting limiting plate 501, and with a switch on the supporting limiting plate 501 for controlling the drive device of the drive wheel 4, when the locking plate 503 engages with the gear 509, the inner rod 507 moves to contact the switch, controlling the drive device that drives the drive wheel 4 to close. The supporting limiting plate 501 guides the limiting guide rod 502. When the forward guide roller 506 is jammed, the forward guide roller 506 drives the limiting guide rod 502 to move closer to the drive wheel 4 through the outer frame 505 and the inner rod 507. The limiting guide rod 502 drives the locking plate 503 to move synchronously, thereby driving the locking plate 503 to engage with the gear 509, realizing the locking and locking operation, and preventing the drive wheel 4 from continuing to move and causing the coal car 1 to overturn.

[0043] For details, please refer to the appendix. Figure 4 and attached Figure 6 An adaptive spring 504 is sleeved on the outer surface of the limiting guide rod 502. The two ends of the adaptive spring 504 are fixedly installed on the inner rod 507 and the supporting limiting plate 501, respectively. By setting the adaptive spring 504, the adaptive spring 504 is used to drive the locking plate 503 and the forward guide roller 506 to automatically return to their original positions. At the same time, it can apply a forward force to the forward guide roller 506 to prevent the forward guide roller 506 from getting stuck when it encounters broken material or small protrusions, thus ensuring the normal transportation operation of the coal car 1.

[0044] Example 2

[0045] For details, please refer to the appendix. Figure 1 Appendix Figure 3 -Appendix Figure 5 Unlike Embodiment 1, this embodiment is used to achieve automatic correction after the drive wheel 4 deviates from the track. Both sides of the housing base 2 are provided with a deviation correction mechanism 6. The deviation correction mechanism 6 includes a number of reset frames 607 corresponding to the number of drive wheels 4. The reset frames 607 are located on the side of the drive wheel 4 and have a guide slope for guiding the drive wheel 4. A support rod 604 is installed on the reset frame 607 and a connecting block 605 is fixed on the outer surface of the support rod 604. The same sliding rod 606 is fixedly installed between two connecting blocks 605 on the same side. Two inclined strip slides are opened on the housing base 2, and the two sliding rods 606 are slidably arranged in the two strip slides respectively.

[0046] By setting up a reset frame 607, a support rod 604, a connecting block 605, and a sliding rod 606, when the drive wheel 4 derails, the drive block falls onto the reset frame 607, driving the reset frame 607 downwards until it contacts the ground. During the downward movement of the reset frame 607, the support rod 604 moves downwards synchronously. The support rod 604 drives the sliding rod 606 downwards through the connecting block 605. The sliding rod 606 slides in the strip track, causing it to move towards the drive wheel 4 and move in the opposite direction to the drive wheel 4. At the same time, under the action of the guide slope on the surface of the reset frame 607, the drive wheel 4 will move back onto the track, automatically correcting the deviation and achieving reset.

[0047] For details, please refer to the appendix. Figure 1 Appendix Figure 3 -Appendix Figure 5 The top of the two support rods 604 on the left and right sides is fixed with the same connecting plate 601. Both sides of the housing base 2 are fixed with support plates 602. Multiple elastic expansion joints 603 are installed on the support plates 602. The connecting plate 601 is fixedly connected to the output end of the elastic connector on the same side.

[0048] By setting up the elastic expansion joint 603, the support plate 602 and the connecting plate 601, the support plate 602 supports and fixes the spring expansion joint. After the drive wheel 4 completes the correction and reset work, under the action of the spring expansion joint, the connecting plate 601 will drive the support rod 604 downward, and the support rod 604 will drive the reset frame 607 upward in sync, so that the reset frame 607 returns to its original position, which is convenient for the next work.

[0049] For details, please refer to the appendix. Figure 3 and attached Figure 4 A sliding block 302 is fixed on the surface of the movable base 301, and the sliding block 302 is slidably disposed in the sliding groove opened at the bottom of the box carrier 2;

[0050] By setting up the sliding block 302, the sliding block 302 guides the moving base 301. At the same time, when the drive wheel 4 derails, the drive wheel 4 will only cause the moving base 301 to shift, without affecting the position of the coal car 1 itself, thus preventing the coal car 1 from shaking and ensuring that the deviation correction mechanism 6 can be used normally.

[0051] For details, please refer to the appendix. Figure 3 and attached Figure 6 The sliding block 302 is configured as an inverted trapezoid, and the sliding groove is configured as an inverted trapezoidal groove that cooperates with the sliding block 302;

[0052] By setting the sliding block 302 as an inverted trapezoid and cooperating with the inverted trapezoidal groove, the problem of the sliding block 302 falling off the housing carrier 2 is effectively avoided.

[0053] Working principle:

[0054] During the transportation operation of the coal transport vehicle 1, the spring buffer 703 can buffer the wheel frame 701 and the drive wheel 4. When the transport vehicle tilts due to gravity, the movable base 301 and the sliding frame 704 move downward under force, causing the wheel frame 701 to contact the sensor 702. The sensor 702 is electrically connected to the drive motor 305 through an externally installed controller, which controls the drive motor 305 to drive the threaded rod 304 to rotate. The rotation of the threaded rod 304 drives the counterweight 303 to move, adjusting the position of the counterweight 303 and automatically adjusting the center of gravity of the transport vehicle itself.

[0055] When there is a problem with the track, the forward guide roller 506 will get stuck. When there is a problem with the track, the forward guide roller 506 will get stuck. The drive assembly will drive the locking plate 503 to move along with it, so that the locking plate 503 moves closer to the locking part and locks the drive wheel 4 in contact with the locking part. This will forcibly stop the drive wheel 4 from moving and wait for the staff to inspect and handle it.

[0056] When drive wheel 4 derails, the drive block falls onto reset frame 607, causing reset frame 607 to move downwards until it contacts the ground. During the downward movement of reset frame 607, support rod 604 moves downwards synchronously. Support rod 604 drives sliding rod 606 downwards through connecting block 605. Sliding rod 606 slides in the strip track, causing sliding rod 606 to move towards drive wheel 4 and move in the opposite direction to drive wheel 4. At the same time, under the action of the guide slope on the surface of reset frame 607, drive wheel 4 will move back onto the track, automatically correcting the deviation and achieving reset.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
