Description

Technical Field

[0001] This application relates to the field of bulk material handling equipment technology, and more specifically, to a method for unloading a tippler system and a tippler system. Background Technology

[0002] A tippler is a large piece of equipment used for unloading bulk materials transported in open railway wagons. It is widely used in power plants, steel plants, ports, and coal storage bases. A complete tippler system usually includes the tippler body, a loaded wagon shunting machine, a transfer platform, and an empty wagon shunting machine. The equipment is interlocked and operates in cycles. Currently, in order to improve unloading capacity and reduce the risk of failure, the existing process layout usually adopts two tippler systems symmetrically arranged and serving as backups for each other to provide equipment redundancy. However, the overall unloading efficiency of the above-mentioned structural arrangement is limited by the operating cycle of the transfer platform. Since the carriages and wheels of railway open wagons are separate structures, the empty wagons have poor stability and are prone to shaking during the translation process. Therefore, the operating speed of the transfer platform can only be maintained at about 0.6 m / s, which is difficult to increase. At the same time, due to the limitations of the interlocking protection between various equipment, when the transfer platform is not aligned with the loaded wagon line, the loaded wagon shunting locomotive cannot push the empty wagons onto the platform. As a result, the tippler body has already been unloaded, but the transfer platform cannot return to align with the loaded wagon line in time. The loaded wagon shunting locomotive is in a waiting state for a long time, which seriously affects the overall unloading efficiency of the tippler system.

[0003] Therefore, how to improve the overall unloading efficiency of the tippler system under the condition of limited operating speed of the tippler platform is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method for unloading a car tipper system, so as to improve the overall unloading efficiency of the car tipper system under the condition that the operating speed of the car transfer platform is limited.

[0005] Another objective of this application is to provide a tipper system for unloading a vehicle using the aforementioned tipper system.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A method for unloading wagons using a tippler system, the tippler system comprising a first tippler system and a second tippler system, the first tippler system comprising a first loaded wagon shunting machine, a first tippler body, a first transfer platform, a first empty wagon shunting machine, a first loaded wagon line, and a first empty wagon line, the second tippler system comprising a second loaded wagon shunting machine, a second tippler body, a second transfer platform, a second empty wagon shunting machine, a second loaded wagon line, and a second empty wagon line, the first transfer platform and the second transfer platform being disposed in the same transfer platform pit, both of which can be moved horizontally to align with either the first loaded wagon line or the second loaded wagon line; when only one loaded wagon enters the first loaded wagon line, the method includes the following steps:

[0008] S1: The first heavy car shunting locomotive pulls the first heavy car into the first tippler body for unloading;

[0009] S2: After the first tippler body is unloaded, the first heavy car shunting machine pulls the second heavy car into the first tippler body, and at the same time, pushes the first empty car that has been unloaded onto the first transfer platform.

[0010] S3: The first transfer platform starts and moves the first empty car from the first loaded car line to the first empty car line. During the movement of the first transfer platform, the second transfer platform starts and aligns with the first loaded car line.

[0011] S4: The first empty car shunting machine pushes the first empty car to the first empty car line, and the first loaded car shunting machine pushes the unloaded second empty car onto the second transfer platform.

[0012] S5: The second transfer platform moves the second empty car body to the second empty car line, and the second empty car shunting machine pushes the second empty car body to the second empty car line; the first transfer platform returns to the position aligned with the first loaded car line;

[0013] S6: The first heavy car shunting locomotive pulls the subsequent heavy car cars into the first tippler body. After the first tippler body unloads the subsequent heavy car cars, the first heavy car shunting locomotive alternately pushes the unloaded empty car cars onto the first transfer platform and the second transfer platform until the entire train of heavy car cars is unloaded.

[0014] Optionally, in the unloading method of the above-mentioned tippler system, in step S2, after the first loaded car shunting machine pushes the first empty car onto the first transfer platform and places it in place, it moves back a preset safe distance and then returns to prepare to pull the next loaded car.

[0015] Optionally, in the unloading method of the above-mentioned tippler system, both the first transfer platform and the second transfer platform are equipped with wheel tensioners, which are used to tighten the wheels of the empty wagon.

[0016] Optionally, in the unloading method of the above-mentioned tippler system, after the first transfer platform moves the first empty car body to the first empty car line, the first empty car shunting machine starts again after the wheel expander of the first transfer platform is released into place to push the first empty car body to the first empty car line; and the first transfer platform starts to return only after the first empty car body is completely pushed out of the first transfer platform.

[0017] Optionally, in the unloading method of the above-mentioned tippler system, after the first empty car arrives at the first transfer platform, the wheel tensioner on the first transfer platform tightens the wheels and the first loaded car shunting machine moves back a safe distance, the first transfer platform is then started to move toward the first empty car line.

[0018] Optionally, in the unloading method of the above-mentioned tippler system, during the execution of steps S1 to S6, only the first tippler body and the feeder, belt conveyor, ventilation equipment and dust removal equipment below it are started, while the second car transfer platform and the second empty car shunting machine are started at the same time, and the second tippler body and the feeder, belt conveyor, ventilation equipment and dust removal equipment below it remain in a stopped state.

[0019] Optionally, in the unloading method of the above-mentioned tippler system, when two heavy wagons enter the first heavy wagon line and the second heavy wagon line respectively, the first tippler system and the second tippler system operate independently and perform tipping operations simultaneously.

[0020] Optionally, in the unloading method of the above-mentioned tippler system, in step S4, when the first loaded car shunting machine pushes the second empty car onto the second transfer platform, the first transfer platform is in the process of moving towards the first empty car line, unloading the empty car, or returning.

[0021] A tippler unloading system includes a first tippler system and a second tippler system. The first tippler system includes a first loaded car shunting machine, a first tippler body, a first transfer platform, a first empty car shunting machine, a first loaded car line, and a first empty car line. The second tippler system includes a second loaded car shunting machine, a second tippler body, a second transfer platform, a second empty car shunting machine, a second loaded car line, and a second empty car line. The first transfer platform and the second transfer platform are arranged in the same transfer platform pit, and both the first transfer platform and the second transfer platform can be moved horizontally within the transfer platform pit to align with any one of the first loaded car line, the second loaded car line, the first empty car line, and the second empty car line.

[0022] The tippler unloading system also includes a controller configured to perform the unloading method of the tippler system as described in any of the preceding claims.

[0023] Optionally, in the above-mentioned tippler unloading system, the transfer platform pit has a clearance length along the translation direction of the first transfer platform and the second transfer platform, and the clearance length ensures that the first transfer platform and the second transfer platform do not interfere with each other when they translate within the same transfer platform pit.

[0024] The unloading method of the tippler system provided in this application, by setting the first and second tippler platforms in the same tippler pit, allows both tippler platforms to be moved horizontally to align with either of the two loaded car lines, breaking the limitation of the existing process layout where the two tippler platforms are independent and their operating ranges are not interconnected. Based on this, when only one loaded car is entering the first loaded car line, as the first tippler platform receives the empty car and moves horizontally towards the first empty car line, the second tippler platform starts to align with the first loaded car line. The first loaded car shunting machine does not need to wait for the first tippler platform to return; it can directly push the next empty car, after it has been tipped over, onto the second tippler platform. The two tippler platforms are then sequentially handed over. This system replaces the existing idle time spent by the shunting locomotive waiting for the transfer platform to move empty wagons, transforming it into continuous working time. Without increasing the operating speed of the transfer platform or altering the individual structure of each piece of equipment, it significantly shortens the unloading cycle of a single wagon and improves the overall unloading efficiency of the tippler system. At the same time, this operation only requires the addition of a second transfer platform and a second empty wagon shunting locomotive to the existing equipment. It does not require opening the second tippler itself and its supporting equipment, nor does it require manual disassembly and locomotive relocation of the entire train of loaded wagons. The additional equipment has low drive power, low energy consumption and maintenance costs, balancing unloading efficiency and operating costs.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] like Figure 1 and Figure 2 As shown, this application provides an unloading method for a tippler system, used to adjust the unloading process of the tippler system. Specifically, as... Figure 1As shown, the tippler system applicable to this unloading method mainly includes a first tippler system 10 and a second tippler system 20 arranged symmetrically. The first tippler system 10 includes a first loaded car shunting machine 110, a first tippler body 120, a first transfer platform 130, a first empty car shunting machine 140, a first loaded car line 150, and a first empty car line 160. The second tippler system 20 includes a second loaded car shunting machine 210, a second tippler body 220, a second transfer platform 230, a second empty car shunting machine 240, a second loaded car line 250, and a second empty car line 260. It should be noted that in the above structure, the loaded car shunting locomotive is used to traction loaded car 40 and push empty car 50. It can adopt a gear and rack drive or winch traction traveling structure and is equipped with frequency conversion speed regulation to achieve low speed and high torque in traction mode and high speed in return mode. The tippler body is used to clamp the car and flip it over for unloading. The transfer platform is a traveling trolley that carries the entire car and moves it horizontally in a direction perpendicular to the track. Its platform is laid with tracks that connect with the loaded car line and the empty car line. It moves horizontally along the tracks in the transfer platform pit 30 through traveling wheels and drive motor. The empty car shunting locomotive is used to push the empty car 50 out of the transfer platform. The above-mentioned structures are the same as or similar to the existing technology structures, and will not be described in detail here.

[0037] Based on the above structure, the tippler system in this application eliminates the isolation area between the two transfer platform pits 30 in the existing arrangement, so that the first transfer platform 130 and the second transfer platform 230 are set in the same transfer platform pit 30, and the tracks in the pit are arranged in a continuous manner. Correspondingly, the translational stroke of the first transfer platform 130 and the second transfer platform 230 both cover the first loaded car line 150 and the second loaded car line 250, so that both can be translated to align with either of the two loaded car lines. Furthermore, both can also be aligned with the first empty car line 160 and the second empty car line 260. Limit switches, encoders or position sensors can be set at the alignment positions of each line to detect whether the transfer platform is aligned with the corresponding line.

[0038] Furthermore, based on the aforementioned tippler system, such as Figure 2 As shown, when only one loaded wagon 40 enters the first loaded wagon line 150, the unloading method provided in this application includes at least the following steps:

[0039] S1: Unloading of heavy car cars. The first heavy car shunting locomotive 110 pulls the first heavy car car into the first tipper body 120. The first tipper body 120 clamps and flips the first heavy car car and completes the unloading.

[0040] S2: As the empty wagon moves forward, after the first loaded wagon is unloaded, the first loaded wagon shunting locomotive 110 pulls the second loaded wagon into the first tipper body 120. At the same time, the first empty wagon, which has been unloaded, is pushed onto the first transfer platform 130 by the pushing action of the traction action.

[0041] S3: The first transfer platform starts, moving the first empty car from the first loaded car line 150 to the first empty car line 160. During the movement of the first transfer platform 130, the second transfer platform 230 starts and aligns with the first loaded car line 150, waiting to receive the next empty car 50.

[0042] S4: Empty car is pushed out. The first empty car shunting locomotive 140 pushes the first empty car to the first empty car line 160. At the same time, the first loaded car shunting locomotive 110 pushes the unloaded second empty car onto the second transfer platform 230, which is already in place.

[0043] S5: The first transfer platform resets, the second transfer platform 230 moves the second empty car to the second empty car line 260, the second empty car shunting machine 240 pushes the second empty car to the second empty car line 260, and the first transfer platform 130 returns to the position aligned with the first loaded car line 150.

[0044] S6: The first transfer platform continues to operate. The first heavy car shunting locomotive 110 pulls the subsequent heavy car 40 into the first tippler body 120. After the first tippler body 120 unloads the subsequent heavy car 40, the first heavy car shunting locomotive 110 alternately pushes the unloaded empty car 50 onto the first transfer platform 130 and the second transfer platform 230.

[0045] The tipper system operates in a cycle as described in steps S1-S6 above, until the entire train of 40 heavy-duty wagons is tipped over.

[0046] It should be noted that the unloading method of the tippler system provided in this application, by setting the first transfer platform 130 and the second transfer platform 230 in the same transfer platform pit 30, allows both transfer platforms to be moved horizontally to align with either of the two loaded car lines, thus breaking the limitation of the existing process layout where the two transfer platforms are independent and their operating ranges are not interconnected. Based on this, through the cyclical operation of steps S1-S6, the second tippler system 20, which is intended as a backup in case of failure, is made available for routine use, thus enabling the first transfer platform 130 to receive empty wagons 50 and move them horizontally to the first empty car line 160. During the process, the second transfer platform 230 starts and aligns with the first loaded car line 150. The first loaded car shunting locomotive 110 does not need to wait for the first transfer platform 130 to return, and can directly push the next empty car after unloading onto the second transfer platform 230. The two transfer platforms take turns receiving and transferring the empty car 50, thereby transforming the idle time of the loaded car shunting locomotive waiting for the transfer platforms to go back and forth in the existing operation into continuous working time. It can significantly shorten the unloading cycle of a single car without increasing the operating speed of the transfer platforms or changing the individual structure of each piece of equipment, and improve the overall unloading efficiency of the tippler system.

[0047] It should also be noted that during the above-mentioned operation, only the second car transfer platform 230 and the second empty car shunting machine 240 need to be added on the basis of the continuously operating first tippler system 10, without opening the second tippler body 220 and its supporting equipment, and without manually disassembling the entire train of loaded cars 40 and transferring locomotives, which can meet the operational requirements of the tippler system unloading method of this application. The additional equipment has low drive power, low energy consumption and maintenance costs, and takes into account both unloading efficiency and operating costs.

[0048] Furthermore, in the unloading method of the tippler system provided in this application embodiment, in step S2, after the first loaded car shunting machine 110 pushes the first empty car onto the first transfer platform 130, it moves back a preset safety distance before returning to prepare to pull the next loaded car 40. It should be noted that when the transfer platform starts to move while carrying the empty car 50, if the loaded car shunting machine is still near the boundary of the transfer platform, there is a risk of motion interference between the two, and the operator cannot confirm that the car has completely left the pushing range of the shunting machine. Therefore, a safety distance is set to reduce the risk of interference. The value of the safety distance is based on the first loaded car... The shunting locomotive 110 and the first transfer platform 130 and the empty wagons 50 on it shall not interfere with each other's movement. It can be calibrated on site according to the equipment's external dimensions, travel margin and interlocking requirements. In some embodiments, position detection elements, such as proximity switches, encoders or radio frequency identification (RFID) position tags, can be set on the running track of the first loaded shunting locomotive 110. When the first loaded shunting locomotive 110 is detected to have moved backward past the calibrated safe position, the detection element sends a position signal. This signal is connected to the system interlocking circuit as one of the prerequisites for allowing the first transfer platform 130 to start.

[0049] After the first heavy car shunting locomotive 110 retreats to a safe distance, it can return at high speed to the waiting position of the first heavy car line 150 to prepare to pull the next heavy car 40. Its return process and the translation process of the first car transfer platform 130 are carried out in parallel without taking up time for each other, thus further compressing the operation cycle.

[0050] Furthermore, such as Figure 5 and Figure 6 As shown, the open railway wagon's carriage 70 and wheels 80 are separate structures. The carriage 70 sits on the bogie of the wheels 80, and the two are not rigidly connected. This results in poor overall stability of the empty wagon 50, posing a certain risk of tilting and overturning during translation. Therefore, as... Figure 3 and Figure 4 As shown, in some embodiments of this application, both the first transfer platform 130 and the second transfer platform 230 are equipped with wheel tensioners 60 for tensioning the wheels 80 of the empty wagon 50. Specifically, the wheel tensioners 60 are arranged in pairs on both sides of the track on the transfer platform, corresponding to the positions of the wheels 80 of the wagon, and as shown... Figure 3As shown, the wheel expander 60 can include a support 610, a tensioning arm 620, and a drive cylinder 630. The support 610 is fixed to the platform of the transfer platform, the tensioning arm 620 is hinged to the support 610, and the drive cylinder 630 can be a hydraulic cylinder or a pneumatic cylinder. When the drive cylinder 630 extends, it pushes the tensioning arm 620 to swing, causing the tensioning block at the end of the tensioning arm 620 to open to both sides and press against the rim or tread side of the wheel 80. The pair of wheel expanders 60 press against the wheel 80 from the inside of the wheel 80 to both sides, thereby holding the wheel 80 tightly and fixing it on the track of the transfer platform. This can suppress the movement and tilting of the empty car 50 relative to the transfer platform during the translation process, and provide structural protection for the smooth transfer of the empty car 50 on the transfer platform.

[0051] Based on the above embodiments, in order to improve the safety of the transfer process of empty car 50 to the empty car line and reduce the risk that the empty car 50 may not be completely transferred to the empty car line due to abnormal operation of the transfer platform, after the first transfer platform 130 moves the first empty car to the first empty car line 160, as follows: Figure 4 As shown, the first empty car shunting machine 140 can only start after the wheel tensioner 60 of the first transfer platform 130 has been fully released to push the first empty car to the first empty car line 160. Furthermore, the first transfer platform 130 only starts to return after the first empty car has been completely pushed out, thus enhancing the safety of the transfer process through interlocking protection. It should be noted that a limit switch or pressure detection element can be installed on the drive cylinder 630 of the wheel tensioner 60. When the tensioning arm 620 is fully returned to its original position and the pressure in the rodless chamber of the drive cylinder 630 drops to the released state, the limit switch or pressure relay sends a release signal. The alignment signal of the first transfer platform 130 with the first empty car line 160, together with this release signal, constitutes the starting permission condition for the first empty car shunting machine 140. Both are indispensable, thereby preventing forced pushing of the car while the wheels 80 are still in a tensioned state, and preventing damage to the wheel tensioner 60, wheels 80, and pushing mechanism due to stress.

[0052] Correspondingly, a wheel detection sensor or photoelectric switch can be installed at the exit end of the upper track of the first transfer platform 130 to detect whether the tail of the empty car 50 has completely passed the boundary of the transfer platform. Only when the empty car 50 is detected to have been completely pushed out will the system allow the first transfer platform 130 to start returning, preventing the tail of the car from scraping against the transfer platform during translation. The aforementioned interlocking chain on the lower platform side ensures the safety and reliability of the process of transferring the empty car 50 from the transfer platform to the empty car line.

[0053] Furthermore, in some embodiments of this application, in order to ensure that the empty car 50 can smoothly reach the transfer platform and that the movement of the transfer platform will not interfere with other equipment, the interlocking sequence on the platform side of the empty car 50 is further limited. Specifically, after the first empty car 50 arrives at the first transfer platform 130, the wheel tensioner 60 on the first transfer platform 130 needs to tighten the wheels 80, and the first loaded car shunting locomotive 110 needs to retreat to a safe distance before the first transfer platform 130 starts moving towards the first empty car line 160. Specifically, after the empty car 50 is pushed onto the first transfer platform 130 and is in place, the arrival detection on the platform... When the component sends a car body arrival signal, the system controls the drive cylinder 630 of the wheel tensioner 60 to actuate, and the tensioning arm 620 presses against the wheel 80. When the pressure of the drive cylinder 630 rises to the set value or the tensioning arm 620 reaches the tensioning stroke, the pressure relay or limit switch sends a tensioning confirmation signal. At the same time, as in the aforementioned embodiment, after the first loaded car shunting machine 110 retreats to a safe distance, the position detection element sends a safe position signal. The aforementioned car body arrival signal, tensioning confirmation signal, and safe position signal are connected to the controller. Only after all three conditions are met can the drive motor of the first transfer platform 130 be energized and started. The interlocking logic in this embodiment makes the transfer process safer and more stable, avoiding interference problems caused by the operation of two empty car lines. Among them, the tensioning confirmation ensures that the split-structure car body is reliably anchored before translation, preventing the empty car body 50 from shaking or even overturning during translation acceleration and deceleration; the safe position confirmation ensures that the loaded car shunting machine has moved out of the movement range of the transfer platform, avoiding equipment interference.

[0054] It should be noted that the interlocking sequence of the second transfer platform 230 side is the same as that of the first transfer platform 130 side mentioned above, and will not be repeated here.

[0055] Furthermore, in the unloading method of the tippler system provided in this application embodiment, in order to reduce equipment operating costs, during the execution of steps S1 to S6, only the first tippler body 120 and the feeder, belt conveyor, ventilation equipment, and dust removal equipment below it are started, while the second transfer platform 230 and the second empty car shunting machine 240 are started simultaneously. The second tippler body 220 and the feeder, belt conveyor, ventilation equipment, and dust removal equipment below it remain shut down. Specifically, the feeder below the tippler body is used to receive and unload materials, the belt conveyor is used to transport materials outwards, and the ventilation equipment and dust removal equipment are used to suppress dust generated during tipping. This auxiliary equipment has high installed power, high energy consumption during continuous operation, and the workload for starting, stopping, and maintenance increases significantly with operating time. In the operating mode of this embodiment, the entire unloading task of the train car is undertaken by the first tipper body 120. Therefore, only the second transfer platform 230 and the second empty shunting machine 240 of the second tipper system 20 participate in the operation. The driving power of the second transfer platform 230 and the second empty shunting machine 240 is much smaller than that of the tipper body and its auxiliary equipment. Therefore, while realizing the alternating relay of the two transfer platforms and eliminating waiting time, the additional energy consumption and maintenance are very small. Compared with the scheme of manually dividing the entire loaded train car into two parts and simultaneously operating two tipper systems at full load, this embodiment also saves the time of the locomotive transferring the second half of the train car to another loaded track and the workload of manually disconnecting and connecting the brake air pipes between the cars, thus achieving a better balance between efficiency and operating cost.

[0056] Furthermore, in the unloading method of the tippler system provided in this application embodiment, when two trains of loaded wagons 40 enter the first loaded wagon line 150 and the second loaded wagon line 250 respectively, the first tippler system 10 and the second tippler system 20 operate independently and perform unloading operations simultaneously. Under this condition, the first loaded wagon shunting machine 110, the first tippler body 120, the first transfer platform 130 and the first empty wagon shunting machine 140 form the first operating line, which undertakes the unloading of the entire wagon on the first loaded wagon line 150; while the second loaded wagon shunting machine 210, the second tippler body 220, the second transfer platform 230 and the second empty wagon shunting machine 240 form the second operating line, which undertakes the unloading of the entire wagon on the second loaded wagon line 250. The two operating lines proceed in parallel and do not affect each other.

[0057] Correspondingly, the operation mode of the tippler system can be divided into single-row relay mode and double-row independent mode, which can be switched by the operator through the operation interface or by issuing instructions through the scheduling system according to the arrival plan. That is, when a single-row arrival occurs, the alternating relay process described in the above embodiment is executed. When a double-row arrival occurs, the two tippler platforms only travel back and forth between the loaded and empty lines of the system, that is, they revert to the existing conventional operation mode. Since the first tippler platform 130 and the second tippler platform 230 are located in the same tippler pit 30, the control system can divide and manage the activity areas of the two tippler platforms in the double-row independent mode, so that the two platforms can move horizontally within the corresponding sections in the pit. Therefore, the layout modification of this application improves the efficiency of single-row operation while fully retaining the original ability of dual-machine parallel operation, thus having stronger process adaptability.

[0058] Furthermore, it should be noted that in the unloading method of the tippler system provided in this application embodiment, in step S4, when the first loaded car shunting machine 110 pushes the second empty car onto the second transfer platform 230, the first transfer platform 130 is in the process of moving towards the first empty car line 160, unloading the empty car 50, or returning. That is, at the moment when the first loaded car shunting machine 110 performs the pushing action, the first transfer platform 130 has not yet returned to align with the first loaded car line 150. It is in any intermediate state of a single work cycle process, that is, the complete work cycle of "transfer-unloading-return". The task has been taken over by the second transfer platform 230, which has been aligned and positioned in advance. It should also be noted that in the existing wagon tipper system, after the existing shunting locomotive pushes the Nth empty wagon 50 onto the platform, it must wait in place for the transfer platform to complete the three consecutive stages of translation, unloading, and return before pushing the N+1th empty wagon 50. The waiting time is almost equal to the complete round-trip cycle of the transfer platform. In this embodiment, the above three stages of the first transfer platform 130 and the receiving and transferring stages of the second transfer platform 230 are carried out in parallel on the time axis. The pushing rhythm of the shunting locomotive depends only on the unloading rhythm of the tipper body. The round-trip cycle of the transfer platform is shared by the two devices. As a result, the original bottleneck of the transfer platform is removed from the critical path of the operation cycle, and the unloading cycle of a single wagon is significantly shortened. Moreover, this effect does not depend on the increase of the operating speed of the transfer platform, thus avoiding the limitation of translation speed on the split wagon structure 70.

[0059] Furthermore, another aspect of this application provides a tippler unloading system. Specifically, the tippler unloading system includes a first tippler system 10 and a second tippler system 20 arranged symmetrically. The first tippler system 10 includes a first loaded car shunting machine 110, a first tippler body 120, a first transfer platform 130, a first empty car shunting machine 140, a first loaded car line 150, and a first empty car line 160. The second tippler system 20 includes a second loaded car shunting machine 210, a second tippler body 220, a second transfer platform 230, and a second empty car shunting machine 240. 40. The second loaded car line 250 and the second empty car line 260. It should be noted that, unlike the existing arrangement, in this embodiment of the application, the first transfer platform 130 and the second transfer platform 230 are set in the same transfer platform pit 30. The tracks for the transfer platforms to travel in the pit are arranged in a continuous manner. The first transfer platform 130 and the second transfer platform 230 can be moved horizontally within the transfer platform pit 30 to a position aligned with any one of the first loaded car line 150, the second loaded car line 250, the first empty car line 160 and the second empty car line 260. That is, the horizontal movement of each transfer platform covers the alignment position of the four lines.

[0060] Based on this, the tippler unloading system also includes a controller, which can be a programmable logic controller (PLC) or an industrial computer. It is electrically connected to the drive units of each loaded shunting machine, tippler body, transfer platform, and empty shunting machine, as well as the position detection elements, arrival detection elements, and tension detection elements arranged at each alignment position, transfer platform surface, and shunting machine running track. It should be further noted that the controller is configured to execute the unloading method provided in any of the above embodiments. Based on the signals fed back by each detection element, the controller outputs start, stop, speed adjustment, and interlocking commands for each device according to a preset program, realizing the automatic operation and switching of two working modes: single-row relay and double-row independent, ensuring the timing accuracy and operational safety of the alternating relay process.

[0061] Furthermore, in the tipper unloading system provided in this application embodiment, the transfer platform pit 30 has a clearance length along the translational direction of the first transfer platform 130 and the second transfer platform 230. This clearance length ensures that the first transfer platform 130 and the second transfer platform 230 do not interfere with each other when they translate within the same transfer platform pit 30. Specifically, when adapting the existing structure, the isolation area between the original two transfer platform pits 30 can be opened up to form a connected integral pit, and the two ends of the pit in the translational direction are respectively A certain distance beyond the outermost track forms a buffer zone for temporary parking of the transfer stations. Based on this, when one transfer station is receiving or unloading a car at the alignment position on a certain track, the other transfer station can park at the buffer zone or be on its way to another alignment position, and the motion envelopes of the two do not overlap. In the single-line relay mode, the first transfer station 130 and the second transfer station 230 can also use the buffer zone to achieve staggered parking and staggered passage, ensuring smooth connection of the alternating alignment with the first heavy car line 150.

[0062] It should be further explained that the specific value of the avoidance length can be determined according to the external length, braking distance and safety margin of the transfer platform. Moreover, this structure only involves the civil engineering modification of the transfer platform pit 30, without the need to modify the individual structure of the transfer platform and other equipment. The modification cost is low, and it provides the basic space conditions for the two transfer platforms to work together in the same pit.
