Description

Technical Field

[0001] The invention relates to vehicle dispatching equipment, in particular to a mining rail vehicle pusher system. Background Art

[0002] At present, rail trains are commonly used transportation equipment in coal mines and metallurgical mines. Vehicle dispatching is mainly based on electric locomotives and shunting locomotives, among which rope-type shunting locomotives are the most common. Rope-type shunting locomotives are mainly dispatched by shunting locomotives or slow winches. The existing dispatching methods have the following technical defects: 1. The disadvantage of mine cars falling off the track is easy to cause during shunting. At the same time, there are safety hazards of shunting injuries and equipment damage when electric locomotives are used, and electric locomotives occupy the road for a long time. 2. The wire rope of the rope-type shunting locomotive is easy to slip. 3. The dispatching process is cumbersome, time-consuming and labor-intensive. 4. Mine cars are easily damaged when shunting with a slow winch. The overall operation is difficult and the maintenance workload is large. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a mining rail vehicle pusher system, which has a reasonable design, is easy to operate, has a high safety factor, has a strong shunting capability, is easy to maintain, can effectively reduce the difficulty of shunting, and improves operating efficiency.

[0004] The present invention discloses a mining rail vehicle pusher system, comprising a pusher and a pusher track. The pusher track is arranged inside the train track, that is, between two steel rails of the train track. The pusher is arranged on the pusher track, and comprises a power supply box, a pusher part, a control device and a driving mechanism. The two ends of the pusher are pusher parts, and at least one driving mechanism, a control device and a power supply box are connected in sequence between the two pusher parts through a connecting carriage. The pusher part cooperates with the bumper of the train, and can contact with the bumper or be separated from the bumper.

[0005] The overall height of the pusher is lower than the chassis height of the mining rail vehicle, and it can pass under the train. It is set on the pusher track by connecting the sports car and the limiting device on the driving mechanism, so that the pusher can be stabilized on the pusher track as a whole. The driving mechanism of the pusher provides power to enable the pusher to run on the pusher track, and the pusher part contacts the train's bumper to push the train to move.

[0006] Advantages of the present invention: 1. It can smoothly push and shunt the car, overcoming the drawbacks of the previous rope-type train pusher for shunting or using a slow winch for shunting, which are prone to derailing of mine cars. At the same time, it avoids the safety hazards of using a battery locomotive for shunting, such as injuring people and damaging equipment, and avoids the phenomenon of the battery locomotive occupying the road for a long time. It effectively saves the battery locomotive and improves work efficiency. 2. It has strong shunting ability. Due to the use of forced transmission, it overcomes the drawback of the wire rope slipping of the previous rope-type train pusher. 3. It adopts a combined pushing and pulling shunting method, and the mine car does not need to be hooked, saving manpower, time, etc. 4. The pushing part is the axle of the mine car. When the pusher advances, the pushing claw automatically lifts. When the pusher retreats and is in a stationary state, the pushing claw is in the falling position. The pushing claw can automatically lift and fall, avoiding the occurrence of damage to the mine car when using a slow winch for shunting in the past. 5. The connection structure between the various components of the pusher is a flexible joint self-balancing structure. 6. The power part is driven by an explosion-proof servo motor through a reducer to output power. The equipment runs smoothly, the speed is adjustable, and the positioning accuracy is high. 7. The operation is simple and convenient, and the maintenance workload is small. 8. The energy part is a mine-use explosion-proof lithium-ion power supply, which has a built-in charging function and supports fast charging. 9. The control device uses a high-performance PLC in cooperation with a servo motor to drive the operation of the pusher. It has functions such as fault diagnosis, position feedback, real-time monitoring of the working state, and access to wired or wireless networks to achieve networking functions. 10. The pusher body can pass through curves or turnouts during the pushing process. 11. The pushing stroke can be designed and manufactured according to the needs of the site.

DETAILED DESCRIPTION

[0019] Now refer to Figure 1 , combined with a specific embodiment, it is described as follows: A mining rail vehicle pusher system described in the present invention includes a pusher and a pusher track. The pusher track is arranged inside the train track 11, that is, between the two rails of the train track 11. The pusher is arranged on the pusher track, and the pusher includes a power box 1, a pusher part 3, a control device 4 and a drive mechanism 5. The two ends of the pusher are pusher parts 3, and at least one drive mechanism 5, a control device 4 and a power box 1 are connected in sequence between the two pusher parts 3 through a connecting sports car 2. The pusher part 3 cooperates with the bumper of the train (the train can be a mine car, an electric locomotive, etc.), and can be in contact with the bumper or separated from the bumper.

[0020] The overall height of the pusher is lower than the chassis height of the mining rail vehicle, and it can pass under the train. It is set on the pusher track by connecting the sports car 2 and the limiting device on the driving mechanism 5, so that the pusher can be stabilized on the pusher track as a whole. The driving mechanism 5 of the pusher provides power to enable the pusher to run on the pusher track, and the pusher part 3 contacts the train's bumper to push the train to move.

[0021] Further, refer to Figure 7 and Figure 8, the trolley track includes a straight track 6, a turning track 7 and a track-changing mechanism. The straight track 6 and the turning track 7 are arranged between the two rails of the train track 11 and on both sides below the rail track-changing mechanism 12. A disconnection area is provided on the straight track 6, and the track-changing mechanism is arranged inside the disconnection area. The track-changing unit includes a transfer track 8, a telescopic cylinder 9 and a support base 10. The support base 10 is arranged at the disconnection area. The transfer track 8 is placed on the support base 10. One end of the transfer track 8 is hinged to a disconnection end of the straight track 6. The telescopic cylinder 9 is arranged on one side of the support base 10, and its piston rod is hinged to the other end of the transfer track 8. The telescopic cylinder 9 can drive the transfer track 8 to swing through the extension and retraction of the piston rod, so that it can be respectively docked with the straight track 6 and the turning track 7.

[0022] The principle of the trolley track changing: The telescopic cylinder 9 drives the transfer track 8 to swing to realize the conversion between the straight track 6 and the turning track 7. Now refer to Figure 9 , when going straight, the piston rod of the telescopic cylinder 9 extends, so that the transfer track 8 connects the two disconnected parts of the straight track into a whole, that is, in the form of a complete straight track. The trolley moves straight on the straight track to push the train to move straight. Now refer to Figure 10 , when turning, the piston rod of the telescopic cylinder 9 retracts, so that the transfer track 8 connects the turning track 7 and a part of the straight track 6 into a whole, that is, in the form of a complete turning track. The trolley can turn through the turning track to push the train to turn.

[0023] Furthermore, now refer to Figure 6 , the driving mechanism 5 includes a housing 501, a servo motor 502, a reducer 503 and a driving gear 504. The housing 501 is placed on the trolley track, and the servo motor 502 and the reducer 503 are arranged inside it. The output shaft of the servo motor 502 is connected to the reducer 503. The output shaft of the reducer 503 passes through the bottom of the housing 501 and is connected to the driving gear 504. One side surface of the web of the trolley track has a tooth surface 13 structure, and the tooth surface 13 meshes with the driving gear 504. When the servo motor 502 rotates, it can drive the trolley to pass on the trolley track through the meshing structure of the driving gear 504 and the tooth surface 13. At the same time, the meshing structure of the driving gear 504 and the tooth surface 13 can also play a limiting role, equivalent to a limiting device.

[0024] Preferably, the servo motor 502 is slidably connected to the inner bottom surface of the housing 501 through the first guide rail 505, and the reducer 503 is slidably connected to the inner end surface of one end of the housing 501 through the second guide rail 506. The servo motor 502 and the reducer 503 form a whole, and the whole has a certain sliding stroke through the first and second guide rails, that is, the driving gear 504 has a certain sliding stroke, so that the driving mechanism 5 can cope with the situation where the turning radius is too small. In actual operation, the above sliding stroke should not be too large to ensure that the driving gear 504 is always in mesh with the tooth surface 13 on the side of the rail waist of the cart track.

[0025] Preferably, a limiting mechanism 507 is provided on the bottom surface of the housing 501, that is, on one side of the driving gear 504, and the limiting mechanism 507 includes a roller and a fixing frame, and the roller is located on one side of the driving gear 504 and is provided on the bottom surface of the housing 501 through the fixing frame. The rail waist of the trolley track is located between the driving gear 504 and the roller, and the driving gear 504 is meshed with the tooth surface 13 on one side of the rail waist, and the roller can contact the other side of the rail waist.

[0026] Further, the trolley part 3 includes a base 301, a trolley arm 302 and an electric push rod 303. The base 301 is placed on the trolley track, and the trolley arm 302 is arranged on the top surface thereof, the top end of the trolley arm 302 cooperates with the bumper, and the bottom end thereof is hinged to the base 301, and one end of the base 301, that is, one side of the trolley arm 302 is provided with an electric push rod 303, the cylinder body of the electric push rod 303 is hinged to the base 301, and the piston rod thereof is hinged to the trolley arm 302, and the electric push rod 303 can be extended to rotate the trolley arm 302 to achieve contact and separation between the trolley arm 302 and the bumper.

[0027] Furthermore, a mounting groove is provided at the top end of the cart arm 302, and a roller 304 is provided in the mounting groove.

[0028] Further, refer to Figure 3, the described connecting car 2 includes a support plate (201), positioning wheels 202 and guide wheels 203. On the bottom surface of the support plate 201, a number of guide wheels 203 are arranged on both sides respectively. The guide wheels 203 are close to the side of the rail head of the trolley track. Between every two guide wheels 203 on one side of the support plate 201, positioning wheels 202 are arranged through fixing parts. The positioning wheels 202 are arranged in the track groove of the trolley track. On the top surface of the support plate 201, a rotatable tongue plate 204 is connected through a pin shaft. The tongue plate 204 is fixedly connected with the end fixing parts of each part of the pusher. The connecting car 2 can play the role of connecting each part of the pusher. At the same time, under the action of the positioning wheels 202, the position of the pusher can be fixed, ensuring that the pusher travels stably on the trolley track, which is equivalent to a limiting device.

[0029] Working principle of the pusher: The power supply box 1 can provide electric energy for electric components such as the servo motor 502 and the electric push rod 303. The control device 4 can control the operation of electric components such as the servo motor 502 and the electric push rod 303. For the two pusher parts 3 of the pusher, one is used to push the train forward, and the other is used to push the train backward. When the train moves forward, the staff starts the electric push rod 303 of one pusher part 3 through the control device 4. The electric push rod 303 drives the pusher arm 302 to rotate. When the pusher arm 302 touches the bumper in front of the train, the electric push rod 303 stops running. At this time, the pusher arm 302 of the other pusher part 3 is in a folded state, that is, the pusher arm 302 does not contact the bumper behind the train. Then the staff starts the servo motor 502 through the control device 4. The servo motor 502 rotates forward to make the pusher push the train forward. When the train moves backward, the above operations are adopted to retract the pusher arm 302 used for the train to move forward, that is, the pusher arm 302 is in a folded state. At the same time, the pusher arm 302 of the other pusher part 3 is made to contact the bumper behind the train. The staff starts the servo motor 502, and the servo motor 502 rotates reversely to make the pusher push the train backward.
