Description

Technical Field

[0001] This invention relates to a shunting system and shunting method, specifically applicable to unloading operations of open wagons in railway transportation. Background Technology

[0002] The main function of a shunting and tipping system is to remove goods from open wagons and other railway vehicles. It is a crucial component of a complete tippler unloading line system. The system includes empty wagon tracks, loaded wagon tracks, tipplers, and shunting locomotives for traction. Railway shunting and tipping systems are characterized by high efficiency, speed, and safety, significantly improving unloading speed and efficiency while reducing manual labor. They are suitable for cargo loading and unloading operations in large railway freight stations or loading / unloading yards. Currently, shunting and tipping systems are widely used in bulk material conveying systems in large enterprises such as docks, power plants, steel mills, and coking plants.

[0003] In existing shunting and unloading systems, the existing empty car shunting locomotives typically use a fixed boom structure, and one empty car shunting locomotive can usually only push empty cars on one empty car line. When there are more than one empty car line in the system, an empty car shunting locomotive and empty car shunting locomotive track are required for each empty car line. Multiple sets of car shunting locomotives and empty car shunting locomotive tracks will result in a large layout space required for the shunting and unloading system equipment, which will increase the investment cost. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems existing in the prior art where existing empty car shunting locomotives typically employ a fixed boom structure and a single empty car shunting locomotive can usually only push empty cars on one empty car track. This invention provides a shunting system and method that uses only one empty car shunting locomotive track and one empty car shunting locomotive to handle pushing operations on two empty car tracks.

[0005] To achieve the above objectives, the technical solution of the present invention is: A shunting and unloading system includes a first empty car line, a second empty car line, and a loaded car line arranged in sequence. The first empty car line, the second empty car line, and the loaded car line are parallel to each other. The front end of the first empty car line, the front end of the second empty car line, and the front end of the loaded car line are all coordinated with a car transfer platform. An empty car shunting track parallel to the first empty car track and the second empty car track is provided between them. An empty car shunting machine is provided on the empty car shunting track. A tippler is provided on the loaded car track. A loaded car shunting track parallel to the loaded car track is provided on the side of the loaded car track. A loaded car shunting machine is provided on the loaded car shunting track.

[0006] The empty shunting locomotive includes an empty shunting locomotive body and a pushing device. The empty shunting locomotive body can move along the empty shunting locomotive track. The pushing device includes a main tilting arm and an auxiliary tilting arm. An empty car locking hook device is provided at the top of the main tilting arm. The empty car locking hook device located at the top of the main tilting arm cooperates with the empty open cars on the first empty car track. The middle part of the main tilting arm is hinged to one end of a connecting rod. The bottom of the main tilting arm is hinged to the side of the empty shunting locomotive body near the first empty car track. The side of the empty shunting locomotive body near the second empty car track is hinged to the bottom of the auxiliary tilting arm. The middle part of the auxiliary tilting arm is hinged to the other end of a connecting rod. An empty car locking hook device is provided at the top of the auxiliary tilting arm. The empty car locking hook device located at the top of the auxiliary tilting arm cooperates with the empty open cars on the second empty car track. The empty shunting locomotive is equipped with a first drive device, which is used to control the raising and lowering of the main tilting boom. The output shaft of the first drive device is driven by one end of the pull rod, and the other end of the pull rod is hinged to the middle of the main tilting boom.

[0007] The loaded shunting locomotive includes a loaded shunting locomotive body and a loaded shunting locomotive pitching arm. The loaded shunting locomotive body can move along the loaded shunting locomotive track. The loaded shunting locomotive body is hinged to the bottom of the loaded shunting locomotive pitching arm. The top of the loaded shunting locomotive pitching arm is equipped with a loaded car locking hook device, which cooperates with the open wagons on the loaded track. The shunting locomotive is equipped with a second drive device, which is used to control the raising and lowering of the shunting locomotive's tilting arm.

[0008] The empty car hook locking device includes an empty car hook and an empty car hook box. The empty car hook is located at the rear end of the empty car hook box. The empty car hook box is fixedly connected to the top of the main pitch arm or the auxiliary pitch arm. The empty car hook box is equipped with a first hydraulic unhooking device for controlling the rotation of the hook tongue of the empty car hook. The loaded car hook-locking device includes a loaded car coupler and a loaded car coupler box. The front end and rear end of the loaded car coupler box are each provided with a loaded car coupler. The loaded car coupler box is fixedly connected to the top of the shunting boom of the loaded car. A second hydraulic uncoupling device for controlling the rotation of the hook tongue of the loaded car coupler is provided inside the loaded car coupler box.

[0009] An empty car shunting machine is installed on the empty car shunting machine track. When the main pitching arm of the empty car shunting machine is in a vertical position and the auxiliary pitching arm of the empty car shunting machine is in a horizontal position, the empty car coupler at the top of the auxiliary pitching arm of the empty car shunting machine is 880mm away from the track surface of the second empty car line; when the auxiliary pitching arm of the empty car shunting machine is in a vertical position and the main pitching arm of the empty car shunting machine is in a horizontal position, the empty car coupler at the top of the main pitching arm 1 of the empty car shunting machine is 880mm away from the track surface of the first empty car line. There are at least two shunting machines on the track. When the shunting machine's boom is in a horizontal position, the distance between the shunting machine's top coupler and the track surface is 880mm.

[0010] The first driving device and the second driving device are swing cylinders or motors with reducers.

[0011] The top of the empty shunting locomotive is equipped with a rotation limit device. The input shaft of the rotation limit device is fixedly connected to a second gear. The second gear meshes with a first gear. The first gear is fixedly connected to the output shaft of a first drive device.

[0012] The output shaft of the first drive device is connected to one end of the main shaft via a coupling, and the other end of the main shaft is perpendicularly connected to one end of the rocker arm. The other end of the rocker arm is hinged to the end of the pull rod. The bottom of the first drive device, the bottom of the rotation limiting device, and the top of the base are fixedly connected, and the bottom of the base is fixedly connected to the top of the empty shunting locomotive body.

[0013] The first empty car line is equipped with a first safety stop and a first anti-runaway device, with the first safety stop located between the car transfer platform and the first anti-runaway device. The second empty car line is equipped with a second safety stop and a second anti-runaway device, with the second safety stop positioned between the transfer platform and the second anti-runaway device. The loaded vehicle line is equipped with a third safety stop and a loaded vehicle wheel clamp. The third safety stop is located between the tipper and the transfer platform, and the loaded vehicle wheel clamp is located behind the tipper.

[0014] The shunting method of the above-mentioned unloading and shunting system specifically includes: Step 1: Pulling the cart: The shunting locomotive is controlled to raise its tilt arm to a vertical position. The shunting locomotive is then controlled to travel along the shunting locomotive track and position its tilt arm in front of the open wagon to be tipped. The tilt arm is then lowered and the car coupler at the top of the tilt arm is hooked to the front end of the open wagon to be tipped. The shunting locomotive is then controlled to continue moving along the shunting locomotive track until the open wagon to be tipped enters the tipper. Step 2, unloading: After the open wagons are loaded into the tippler, the coupler of the loaded wagons is uncoupled from the open wagons to be unloaded. Then, the tilt arm of the loaded wagon shunting machine is raised and the loaded wagon shunting machine is moved along the loaded wagon shunting machine track to the rear of the open wagons to be unloaded. The tippler then performs the unloading operation. Step 3: Moving the vehicle: After the tipper unloads the cargo, the transfer platform connects with the loaded shunting machine track. The tilt arm of the loaded shunting machine is lowered, and the loaded car coupler at the top of the tilt arm is hooked with the rear end of the empty car. Then, the loaded shunting machine is moved along the loaded shunting machine track and the empty car is pushed onto the transfer platform. After the empty car is pushed onto the transfer platform, the loaded car coupler is uncoupled from the empty car. After the empty car is uncoupled from the loaded car coupler, the transfer platform moves according to the operator's settings and connects with the first empty car line or the second empty car line. If the transfer platform connects with the first empty car line, proceed to step four; if the transfer platform connects with the second empty car line, proceed to step five. Step 4: Pushing the cart along the first empty line: The pusher on the car transfer platform is controlled to push the empty car onto the first empty car track. The main tilt arm 1 of the empty car shunting machine is raised and the auxiliary tilt arm is lowered, and the machine moves forward along the empty car shunting machine track so that the main tilt arm is in front of the empty car. Then the main tilt arm of the empty car shunting machine is lowered and the auxiliary tilt arm is raised, and the empty car coupler at the top of the main tilt arm is hooked with the front end of the empty car. After the empty car coupler at the top of the main tilt arm is hooked with the front end of the empty car, the empty car shunting machine is controlled to reverse along the empty car shunting machine track and push the empty car to the designated position on the first empty car track to stop. Step 5: Pushing the cart on the second empty line: The pusher on the transfer platform is controlled to push the empty wagon to the second empty wagon track. The main tilt arm of the empty wagon shunting machine is lowered and the auxiliary tilt arm is raised, and the machine moves forward along the empty wagon shunting machine track until the auxiliary tilt arm is in front of the empty wagon. Then, the main tilt arm of the empty wagon shunting machine is raised and the auxiliary tilt arm is lowered, and the empty wagon coupler at the top of the auxiliary tilt arm is hooked with the front end of the empty wagon. After the empty wagon coupler at the top of the auxiliary tilt arm is hooked with the front end of the empty wagon, the empty wagon shunting machine is controlled to reverse along the empty wagon shunting machine track and push the empty wagon to the designated position on the second empty wagon track to stop.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention discloses a shunting and tipping system comprising two empty car lines (a first empty car line and a second empty car line) and one loaded car line. An empty car shunting machine track is provided between the first and second empty car lines, and an empty car shunting machine is installed on the empty car shunting machine track. A tipper for unloading is provided on the loaded car line, and a loaded car shunting machine track is provided on the side of the loaded car line, and a loaded car shunting machine is installed on the loaded car shunting machine track. The loaded car shunting machine pulls open wagons to the tipper for tipping and unloading. After unloading, the empty open wagons are pushed by the loaded car shunting machine to a transfer platform. The transfer platform, according to the operator's selection, transfers the empty open wagons... The cars are transferred to an empty car track, and then an empty car shunting locomotive pushes the empty cars to their designated positions on that track. Therefore, this shunting system has two empty car tracks, allowing for more empty cars to be parked, and the system structure is compact. Furthermore, the shunting locomotive between the two empty car tracks has a main tilting arm on one side for use with the empty cars on the first track and a secondary tilting arm on the other side for use with the empty cars on the second track. One empty car shunting locomotive track and one empty car shunting locomotive can handle the pushing operations for both tracks, resulting in a compact system with minimal space requirements and lower equipment costs. Therefore, this shunting system features two empty car tracks, allowing for more empty cars to be parked, and the double-tilting-arm empty car shunting locomotive can handle the pushing operations for both tracks. The system structure is compact, occupies little space, and has low equipment costs.

[0016] 2. The present invention discloses an empty car shunting machine in a shunting system, comprising an empty car shunting machine body and a pushing device. The empty car shunting machine body can move along the empty car shunting machine track. The pushing device includes a main tilting arm and an auxiliary tilting arm. An empty car locking hook device is provided at the top of the main tilting arm, which cooperates with an empty car on the first empty car track. The middle part of the main tilting arm is hinged to one end of a connecting rod, and the bottom of the main tilting arm is hinged to the side of the empty car shunting machine body near the first empty car track. The empty car shunting machine body is near the second... One side of the empty car track is hinged to the bottom of the auxiliary pitch arm, and the middle of the auxiliary pitch arm is hinged to the other end of the connecting rod. An empty car locking hook device is installed at the top of the auxiliary pitch arm, which cooperates with the empty cars on the second empty car track. Since the middle of the main pitch arm and the middle of the auxiliary pitch arm are connected by a connecting rod, the auxiliary pitch arm lowers synchronously when the main pitch arm rises, and vice versa. The main and auxiliary pitch arms act as counterweights to each other during pitching operations, reducing the load on the drive unit. Therefore, in this design, the main and auxiliary pitch arms on the empty car shunting locomotive act as counterweights to each other during pitching operations, reducing the load on the drive unit.

[0017] 3. In a shunting and tipping system of the present invention, a pusher is installed on the transfer platform. The pusher can push empty open wagons on the transfer platform to the empty wagon line. At the same time, the empty wagon shunting machine only needs to hook the empty open wagons with the empty wagon coupler and push the open wagons on the empty wagon line to the designated position for parking. The pusher on the transfer platform and the empty wagon shunting machine work together, and the empty wagon shunting machine has high pushing efficiency. Meanwhile, at least two loaded wagon shunting machines are set up on the loaded wagon line. During the shunting and tipping operation, while the first loaded wagon shunting machine pushes the empty open wagons that have completed the tipping operation out of the tipper and into the transfer platform, the second loaded wagon shunting machine pulls the remaining open wagons waiting to be tipped into the tipper. The cooperation of multiple loaded wagon shunting machines improves the efficiency of tipping and tipping. Therefore, in this design, a car pusher is installed on the car transfer platform, and an empty car shunting machine that can handle the pushing operations of two empty car lines is installed on the empty car shunting machine track. At least two loaded car shunting machines are installed on the loaded car lines. The loaded car shunting machines can perform pushing and pulling operations, and the unloading and shunting system is highly efficient. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1 to 13 A shunting and unloading system includes a first empty car line 10, a second empty car line 20, and a loaded car line 30 arranged sequentially. The first empty car line 10, the second empty car line 20, and the loaded car line 30 are parallel to each other. The front end of the first empty car line 10, the front end of the second empty car line 20, and the front end of the loaded car line 30 are all coordinated with a transfer platform 60. An empty car shunting machine track 40, parallel to the first empty car track 10 and the second empty car track 20, is provided between the first empty car track 10 and the second empty car track 20. An empty car shunting machine 80 is provided on the empty car shunting machine track 40. A tipper 70 is provided on the loaded car track 30. A loaded car shunting machine track 50, parallel to the loaded car track 30, is provided on the side of the loaded car track 30. A loaded car shunting machine 90 is provided on the loaded car shunting machine track 50.

[0035] The first empty car line 10 is equipped with a first safety stop 101 and a first anti-runaway device 102. The first safety stop 101 is located between the transfer platform 60 and the first anti-runaway device 102. Figure 1 As shown, the first safety stop 101 is located at the front end of the first empty car line 10. The first safety stop 101 is used to prevent an empty car on the first empty car line 10 from sliding forward out of the first empty car line 10; the first anti-rollover device 102 is used to prevent an empty car on the first empty car line 10 from rolling away.

[0036] The second empty car line 20 is equipped with a second safety stop 201 and a second anti-runaway device 202. The second safety stop 201 is located between the transfer platform 60 and the second anti-runaway device 202. Figure 1 As shown, the second safety stop 201 is located at the front end of the second empty car line 20. The second safety stop 201 is used to prevent an empty car on the second empty car line 20 from sliding forward off the second empty car line 20; the second anti-rollover device 202 is used to prevent an empty car on the second empty car line 20 from rolling away.

[0037] The loaded vehicle track 30 is equipped with a third safety stop 301 and a loaded vehicle wheel clamp 302, such as Figure 1 As shown, the third safety stop 301 is located at the front end of the loaded wagon line 30 near the transfer platform, and the loaded wagon wheel clamp 302 is located behind the tippler 70. The loaded wagon wheel clamp 302 is used to clamp the front wheels of the first open wagon in the open wagon group to be unloaded that is parked behind the tippler 70, so as to fix the open wagon to be unloaded and thus safely carry out the uncoupling operation, separating the open wagon group to be unloaded that is parked behind the tippler 70 from the open wagons sent into the tippler 70; the third safety stop 301 is used to prevent the open wagons from sliding forward out of the loaded wagon line 30 after the unloading operation is completed.

[0038] like Figure 3 As shown, the empty shunting locomotive 80 includes an empty shunting locomotive body 3 and a pushing device. The empty shunting locomotive body 3 can move along the empty shunting locomotive track 40. The pushing device includes a symmetrically arranged main tilting arm 1 and a secondary tilting arm 2. An empty car locking hook device 7 is provided at the top of the main tilting arm 1. The empty car locking hook device 7 located at the top of the main tilting arm 1 cooperates with the empty cars on the first empty car line 10. The middle part of the main tilting arm 1 is connected to the connecting rod 4. One end of the main tilting arm 1 is hinged, the bottom of the main tilting arm 1 is hinged to the side of the empty car shunting locomotive body 3 near the first empty car line 10, the side of the empty car shunting locomotive body 3 near the second empty car line 20 is hinged to the bottom of the auxiliary tilting arm 2, the middle part of the auxiliary tilting arm 2 is hinged to the other end of the connecting rod 4, and an empty car locking hook device 7 is provided at the top of the auxiliary tilting arm 2. The empty car locking hook device 7 located at the top of the auxiliary tilting arm 2 cooperates with the empty cars on the second empty car line 20.

[0039] The empty car hook device 7 includes an empty car hook 71 and an empty car hook box 72. The empty car hook box 72 is a long cylindrical hollow box. The empty car hook 71 is located at the rear end of the empty car hook box 72. The empty car hook box 72 is fixedly connected to the top of the main pitch arm 1 or the auxiliary pitch arm 2. The empty car hook box 72 is equipped with a first hydraulic unhooking device 73 for controlling the rotation of the hook tongue of the empty car hook 71.

[0040] The empty shunting locomotive body 3 is equipped with a first drive device 5, which is used to control the raising and lowering of the main pitch boom. The output shaft of the first drive device 5 is connected to one end of the pull rod 6, and the other end of the pull rod 6 is hinged to the middle of the main pitch boom 1.

[0041] The main tilting arm 1 and the auxiliary tilting arm 2 of the empty car shunting locomotive 80 are respectively coordinated with empty cars on two empty car lines. The main tilting arm 1 is used to push empty cars on the first empty car line 10, and the auxiliary tilting arm 2 is used to push empty cars on the second empty car line 20. At the same time, the main tilting arm 1 and the auxiliary tilting arm 2 are connected by a tie rod 6. When the main tilting arm 1 rises, the auxiliary tilting arm 2 falls synchronously. At this time, the auxiliary tilting arm 2 acts as a counterweight to the main tilting arm 1, reducing the load on the first drive unit 5. Similarly, when the main tilting arm 1 falls, the auxiliary tilting arm 2 rises synchronously. At this time, the main tilting arm 1 acts as a counterweight to the auxiliary tilting arm 2, reducing the load on the first drive unit 5.

[0042] like Figure 5 As shown, the main pitch arm 1 and the auxiliary pitch arm 2 are connected by a connecting rod 4. When the main pitch arm 1 rotates to a horizontal position, the auxiliary pitch arm 2 is in a vertical position. At this time, the empty car coupler 71 at the top of the main pitch arm 1 is 880mm away from the track surface of the first empty car line 10. The empty car coupler 71 at the top of the main pitch arm 1 can be aligned with the coupler of the empty car on the first empty car line 10, making it convenient for the empty car coupler 71 at the top of the main pitch arm 1 to hook up with the coupler of the empty car. Figure 7 As shown, when the main pitch arm 1 rotates to the vertical position, the auxiliary pitch arm 2 is in the horizontal position. At this time, the empty car coupler 71 at the top of the auxiliary pitch arm 2 is 880mm away from the track surface of the second empty car line 20. The empty car coupler 71 at the top of the auxiliary pitch arm 2 can be aligned with the coupler of the empty car on the second empty car line 20, so that the empty car coupler 71 at the top of the auxiliary pitch arm 2 can be hooked with the coupler of the empty car on the second empty car line 20.

[0043] like Figure 4 As shown, the loaded shunting locomotive 90 includes a loaded shunting locomotive body 91 and a loaded shunting locomotive pitching arm 92. The loaded shunting locomotive body 91 can move along the loaded shunting locomotive track 50. The side of the loaded shunting locomotive body 91 closest to the loaded car line 30 is hinged to the bottom of the loaded shunting locomotive pitching arm 92. The top of the loaded shunting locomotive pitching arm 92 is provided with a loaded car locking hook device 93, which cooperates with the loaded open wagons on the loaded car line 30.

[0044] The loaded car hook locking device 93 includes a loaded car coupler 931 and a loaded car coupler box 932. The loaded car coupler box 932 is a long cylindrical hollow box. A loaded car coupler 931 is provided at the front end and the rear end of the loaded car coupler box 932. The loaded car coupler box 932 is fixedly connected to the top of the loading arm 92 of the loaded car shunting machine. A second hydraulic unhooking device 933 is provided inside the loaded car coupler box 932 for controlling the rotation of the hook tongue of the loaded car coupler 931.

[0045] The shunting locomotive body 91 is equipped with a second drive device 94, which is used to control the raising and lowering of the shunting locomotive's tilting boom 92. Figure 4 The second drive device 94 is a swing cylinder. The output shaft of the second drive device 94 is provided with a rocker arm and a pull rod. When the output shaft of the second drive device 94 rotates, it drives the tilt arm of the shunting locomotive to rise or fall through the rocker arm and the pull rod.

[0046] like Figure 3 , Figure 4 As shown, the transfer platform 60 is equipped with a pusher, which is used to push empty cars off the transfer platform 60 to the first empty car line 10 or the second empty car line 20. Therefore, only one rear hook is provided on the top of the tilting arm of the empty car shunting locomotive 80. The pusher on the transfer platform 60 works in conjunction with the empty car shunting locomotive 80. The empty car shunting locomotive 80 only needs to push the empty cars pushed to the end of the empty car line near the transfer platform 60 away from the transfer platform 60 to the designated position on the empty car line. There is no need to use the empty car shunting locomotive 80 to pull the empty cars from the transfer platform 60 to the empty car line, reducing the number of times the empty car shunting locomotive 80 moves back and forth along the empty car shunting locomotive track 40, and further improving the efficiency of dispatching operations.

[0047] like Figure 1 , Figure 3 As shown, a heavy car coupler box 932 is installed on the top of the tilting arm 92 of the loaded car shunting machine. A heavy car coupler 931 is installed at each end of the box. The heavy car coupler 931 at the rear end of the box connects to the coupler at the front end of the open wagon to be unloaded, and pulls the open wagon into the tippler 70. The heavy car coupler 931 at the front end of the box connects to the coupler at the rear end of the empty open wagon after unloading, pushing the empty open wagon away from the tippler 70 and onto the transfer platform 60. Using an empty car shunting machine 80 with a double tilting arm structure to assist in pushing operations on two empty wagon lines, while simultaneously using a single-arm loaded car shunting machine 90 to complete pulling and pushing operations on a single loaded wagon line, effectively improves the efficiency of unloading and shunting operations.

[0048] Since only one loaded car line 30 is designed in the unloading shunting system, the loaded car shunting locomotive 90 in this design is also equipped with only one tilting boom for pushing and pulling open cars. Two tilting booms that act as counterweights can also be installed on the loaded car shunting locomotive 90 to reduce the load on the second drive unit 94.

[0049] The first drive device 5 and the second drive device 94 are swing cylinders or motors with reducers. like Figure 13 , Figure 14 As shown, the output shaft of the first drive device 5 is connected to one end of the main shaft 52 via a coupling 59, and the other end of the main shaft 52 is perpendicularly connected to one end of the rocker arm 53. The other end of the rocker arm 53 is hinged to the end of the pull rod 6. The bottom of the first drive device 5 is fixedly connected to the top of the empty shunting locomotive body 3 via a base 51, and the top of the base 51 is fixedly connected to the bottom of the rotation limiting device 8.

[0050] The empty shunting locomotive body 3 is fixedly connected to the rotation limiting device 8. The input shaft of the rotation limiting device 8 is fixedly connected to the second gear 82. The second gear 82 meshes with the first gear 81. The first gear 81 is fixedly connected to the output shaft of the first drive device 5. The rotation limiting device 8 is used to control the rotation angle of the main pitch arm 1 and the auxiliary pitch arm 2 of the empty shunting locomotive body 3.

[0051] like Figure 14 As shown, the first gear 81 is coaxially fixed on the output shaft of the first drive device 5. When the output shaft of the first drive device 5 rotates, it drives the main pitch arm 1 and the auxiliary pitch arm 2 to rotate simultaneously through the rocker arm 4 and the pull rod 6, thereby completing the lifting and lowering action. During the lifting and lowering action of the main pitch arm 1 and the auxiliary pitch arm 2 driven by the rotation of the output shaft of the first drive device 5, the lifting and lowering angle of the main pitch arm 1 and the auxiliary pitch arm 2 is converted into the rotation angle of the output shaft of the first drive device 5. The rotation angle of the output shaft of the first drive device 5 is fed back to the rotation limit device 8 through the first gear 81 and the second gear 82. The rotation limit device 8 is equipped with a cam switch. When the main pitch arm 1 and the auxiliary pitch arm 2 are lifted to the corresponding angle, the cam switch sends a signal and feeds it back to the electrical control system. The electrical control system controls the first drive device 5 according to the signal sent by the cam switch, thereby controlling the lifting and lowering height and lifting and lowering speed of the main pitch arm 1 and the auxiliary pitch arm 2.

[0052] After the entire train of fully loaded open wagons enters the factory, they reach the operating range of the shunting locomotive 90. At this point, the wheel clamp 302, located at the rear of the tippler 70, clamps the front wheels of the first open wagon in the train, and then the unloading and shunting operation begins. The shunting method specifically includes: Step 1: Pulling the cart: After the wheel clamp 302 clamps the front wheels of the first open wagon in the train of open wagons, the shunting boom 92 of the shunting boom 90 is raised to a vertical position. The shunting boom 90 is then moved along the shunting boom track 50 and the shunting boom 92 is positioned in front of the open wagons to be unloaded. The shunting boom 92 is then lowered and the car coupler 931 at the top rear of the shunting boom 92 is hooked to the front end of the train of open wagons to be unloaded. The wheel clamp 302 is then released, and the shunting boom 90 continues to move along the shunting boom track 50 until the first two open wagons of the train enter the tippler 70. The wheel clamp 302 clamps the front wheels of the first open wagon in the train of open wagons that have not entered the tippler 70. The two open wagons that have entered the tippler 70 are then uncoupled from the train of open wagons that have not entered the tippler 70.

[0053] Step 2, unloading: After the open wagons to be unloaded enter the tippler 70, the shunting locomotive 90 pulls the two open wagons to be unloaded forward and accurately stops them in the working area of ​​the tippler 70. The two open wagons to be unloaded are uncoupled from the car coupler 931, the shunting locomotive's tilting arm 92 rises, and then the shunting locomotive 90 retreats along the shunting locomotive track 50 to the rear of the open wagons to be unloaded. The car pressing device of the tippler 70 presses down on the two open wagons to be unloaded, and the car approaching device approaches the side of the open wagon's upright. The tippler rotates 160 degrees to unload the material. After the material is unloaded, the tippler rotates back to the zero-degree starting position, the car pressing device releases pressure, and the car approaching device releases its approach, completing the unloading operation of the two open wagons. After the unloading operation is completed, the open wagons become empty open wagons.

[0054] At least two shunting locomotives 90 are installed on the shunting locomotive track 50. When the tippler 70 is performing tipping and unloading operations, while the shunting locomotive 90 at the front of the shunting locomotive track 50 moves backward along the shunting locomotive track 50 to the rear of the open wagon to be tipped, the other shunting locomotives 90 can pull the remaining open wagon trains that have not been tipped close to the tippler 70 to improve the efficiency of the tipping operation.

[0055] Step 3: Moving the vehicle: After the tipper 70 finishes tipping and unloading, the transfer platform 60 connects with the loaded shunting machine track 50. The tilting arm 92 of the loaded shunting machine is lowered, and the loaded car coupler 931 at the top of the tilting arm 92 is hooked with the rear end of the empty car. The loaded shunting machine 90 moves forward along the loaded shunting machine track 50 and pushes the empty car onto the transfer platform 60. Then, the loaded car coupler 931 is uncoupled from the empty car. After the loaded car coupler 931 is uncoupled from the empty car, the transfer platform 60 moves according to the operator's settings and connects with the first empty car line 10 or the second empty car line 20. If the transfer platform 60 connects with the first empty car line 10, the process proceeds to step four. If the transfer platform 60 connects with the second empty car line 20, the process proceeds to step five.

[0056] The operator controls the movement of the transfer platform 60 based on the parking status of open wagons on the two empty wagon lines, and then selects... After the current group of empty open wagons that have completed the unloading operation are pushed away from the tippler 70 by the shunting locomotive 90 and arrive at the transfer platform 60, the shunting locomotive 90 repeats the operation in step one to pull a group of open wagons parked behind the tippler 70 into the tippler 70 for unloading operation, until the entire train of open wagons has completed the unloading operation.

[0057] Step 4: Pushing the cart along the first empty line: The pusher on the car transfer platform 60 pushes the empty car onto the first empty car line 10. It controls the main tilt arm 1 of the empty car shunting locomotive 80 to rise and the auxiliary tilt arm 2 to fall, and moves forward along the empty car shunting locomotive track 40 so that the main tilt arm 1 is in front of the empty car. Then, it controls the main tilt arm 1 of the empty car shunting locomotive 80 to fall and the auxiliary tilt arm 2 to rise, and controls the empty car coupler 71 at the top of the main tilt arm 1 to hook with the front end of the empty car. After the empty car coupler 71 hooks with the front end of the empty car, it controls the empty car shunting locomotive 80 to move backward along the empty car shunting locomotive track 40 and push the empty car to the designated position on the first empty car line 10 and stop.

[0058] Step 5: Pushing the cart on the second empty line: The pusher on the car transfer platform 60 pushes the empty car onto the second empty car line 20. The main tilt arm 1 of the empty car shunting locomotive 80 lowers and the auxiliary tilt arm 2 rises and moves forward along the empty car shunting locomotive track 40 so that the auxiliary tilt arm 2 is in front of the empty car. Then the main tilt arm 1 of the empty car shunting locomotive 80 rises and the auxiliary tilt arm 2 lowers, and controls the empty car coupler 71 at the top of the auxiliary tilt arm 2 to hook with the front end of the empty car. The empty car shunting locomotive 80 moves backward along the empty car shunting locomotive track 40 and pushes the empty car to the designated position on the second empty car line 20 and stops.

[0059] The principle of this invention is explained as follows: The tipping and shunting system is applicable to coal car unloading operations. When the tipping and shunting system is in operation, the loaded car shunting locomotive 90 pulls the open car loaded with coal to the tipper 70 for tipping and unloading. After unloading, the empty open car is pushed by the loaded car shunting locomotive 90 to the transfer platform 60. The transfer platform 60 carrying the empty open car moves to the empty car line and docks with the first empty car line 10 or the second empty car line 20 according to the operator's choice. After docking, the pusher on the transfer platform 60 pushes the empty open car away from the transfer platform 60 and into the corresponding empty car line. Since the empty car shunting machine track 40 is located between the first empty car line 10 and the second empty car line 20, and the empty car shunting machine 80 on the empty car shunting machine track 40 is provided with a main tilting arm 1 that cooperates with the empty cars on the first empty car line 10 and an auxiliary tilting arm 2 that cooperates with the empty cars on the second empty car line 20 respectively, after the empty cars are transported to an empty car line, the corresponding tilting arm on the empty car shunting machine 80 performs the operation to push the empty cars to the designated position on the empty car line for parking.

Then the main tilt arm (1) of the empty car shunting machine (80) is lowered and the auxiliary tilt arm (2) is raised and the empty car coupler (71) at the top of the main tilt arm (1) is hooked to the front end of the empty car. After the empty car coupler (71) at the top of the main tilt arm (1) is hooked to the front end of the empty car, the empty car shunting machine (80) is controlled to move backward along the empty car shunting machine track (40) and push the empty car to the designated position on the first empty car line (10) to stop. Step 5: Pushing the cart on the second empty line: The pusher on the car transfer platform (60) is controlled to push the empty car to the second empty car line (20). The main pitch arm (1) of the empty car shunting machine (80) is lowered and the auxiliary pitch arm (2) is raised and moved forward along the empty car shunting machine track (40) so that the auxiliary pitch arm (2) is in front of the empty car. Then the main pitch arm (1) of the empty car shunting machine (80) is raised and the auxiliary pitch arm (2) is lowered so that the empty car coupler (71) at the top of the auxiliary pitch arm (2) is hooked with the front end of the empty car. After the empty car coupler (71) at the top of the auxiliary pitch arm (2) is hooked with the front end of the empty car, the empty car shunting machine (80) is controlled to move backward along the empty car shunting machine track (40) and push the empty car to the designated position on the second empty car line (20) and stop.
