Description

Technical Field

[0001] The present invention relates to the technical field of railway vehicle dumper unloading, and in particular, to a multi-functional double-arm car pusher, a multi-functional dumper unloading system, a traction dispatching method and an operation method. Background Art

[0002] The dumper unloading system is an automatic and efficient large-scale unloading device used to unload bulk materials such as coal, ore, and chemical raw materials loaded in railway gondolas. The car pusher is an auxiliary device used to tow and dispatch railway vehicles in the dumper unloading system.

[0003] Railway gondolas are divided into general gondolas and special gondolas. When the dumper unloading system operates, it is correspondingly divided into two operation modes: decoupling operation and non-decoupling operation. Due to the great differences between the two operation modes, usually, the dumper unloading system can only implement one of the operation modes. However, in many cases, the dumper unloading system needs to take into account both general gondolas and special gondolas and needs to have both operation modes in one system. For this reason, in the prior art, two car pushers are arranged in the dumper unloading system. One car pusher is used for the decoupling operation of general gondolas, and the other is used for the non-decoupling operation of special gondolas. In order to optimize the unloading process, two car pushers are configured for the railway gondola dispatching operation in the dumper. One car pusher is equipped with a telescopic hook boom for the traction dispatching operation when unloading non-decoupled special gondolas; the other car pusher is equipped with a pitching hook boom and can pass through the dumper for the traction dispatching operation when unloading decoupled general gondolas.

[0004] The pitching boom of the car pusher in the prior art can only perform the hook operation to tow and decouple the gondola, and the buckling operation of the non-decoupled gondola can only be achieved by the telescopic boom. The telescopic boom has a complex structure, is heavy, has a high cost, a high maintenance cost, and a high installation difficulty. Moreover, no pitching buckling boom is provided in the existing double-arm car pushers. For this reason, the present invention designs a multi-functional double-arm car pusher to realize the operation functions of the above two car pushers through one car pusher. Summary of the Invention

[0005] According to the above-mentioned technical problems, a multi-functional double-arm car pusher and a traction dispatching method are provided.

[0006] The technical means adopted by the present invention are as follows:

[0007] A multi-functional double-arm car pusher, comprising: a car body, a hook boom device, a hanger boom device and a traveling device mounted on the car body. The hook boom device includes a hook boom and a first driving device mounted on the car body. The hook boom adopts a folding structure. The first driving device is connected to the hook boom and is used to drive the hook boom to rotate reciprocally. The hanger boom device includes a hanger boom and a second driving device mounted on the car body. The second driving device is connected to the hanger boom and is used to drive the hanger boom to rotate reciprocally.

[0008] The hook boom and the hanger boom are arranged at intervals on the car body, and the hook boom and the hanger boom are mounted on the same side of the car pusher.

[0009] The end of the hook boom is provided with a hook head for realizing the hook traction operation of the car pusher; the end of the hanger boom is provided with a hanger head for realizing the hanger traction operation of the car pusher.

[0010] Further, the hook boom includes a first arm body and a second arm body. One end of the first arm body is hinged to the car body, and the other end is hinged to one end of the second arm body. The first driving device is connected to the first arm body and the second arm body. By driving of the first driving device, the first arm body rotates around the hinge point between the first arm body and the car body, and the second arm body rotates around the hinge point between the first arm body and the second arm body.

[0011] When the hook boom is operating, the first arm body is always in a horizontal state, and the second arm body completes the scheduling work of the railway car train through pitching motion; when the car pusher is not operating or when the car pusher is hooking or the car pusher needs to pass through the dumper, the first arm body is in a vertically lifted state.

[0012] Further, the first driving device includes a first pitching drive unit, a second pitching drive unit, a first link mechanism and a second link mechanism. The first pitching drive unit is fixed on the car body. The first arm body is connected to the first pitching drive unit through the first link mechanism. The first pitching drive unit drives the first arm body to rotate through the first link mechanism. The second pitching drive unit is fixed on the first arm body. The second arm body is connected to the second pitching drive unit through the second link mechanism. The second pitching drive unit drives the second arm body to rotate through the second link mechanism.

[0013] Further, the hook head is arranged at the other end of the second arm body, and the hook head is a U-shaped groove.

[0014] Further, the front width a of the second arm body is less than the distance A between two open cars, and the maximum contour turning radius r of the second arm body is less than the distance R from the accessories of the railway open car to the turning center of the second arm body.

[0015] Further, the first pitching drive unit and the second pitching drive unit adopt a three-in-one motor drive form or a rack and cylinder drive form.

[0016] Further, the traveling device includes traveling wheels and a traveling drive unit. The traveling wheels are installed on both sides of the lower part of the vehicle body, and the traveling drive unit is fixed on the vehicle body.

[0017] The present invention also provides a traction scheduling method for a multi-functional double-arm car pusher, including the following steps:

[0018] S1. Uncoupling and tipping of general gondola cars:

[0019] S11. The hook boom is lifted. The first arm body and the second arm body of the hook boom are in a straight line and are both in a vertically lifted state, so that the car pusher can pass through the dumper. At this time, the hook boom does not participate in the operation.

[0020] S12. The hooking boom realizes the hooking traction scheduling operation of the railway car train and the gondola car through pitching movement.

[0021] S2. Non-uncoupling and tipping of special gondola cars:

[0022] S21. During normal cyclic operation, the hooking boom is lifted to the vertical and remains in the lifted state all the time. At this time, the hooking boom does not participate in the operation.

[0023] S22. The first arm body of the hook boom descends to the horizontal position and remains stationary.

[0024] S23. The second arm body of the hook boom realizes the hook traction scheduling operation of the railway car train through pitching movement.

[0025] S24. When only the last car of the railway car train remains to be tipped, the hook boom is lifted. The first arm body and the second arm body of the hook boom are in a straight line and are both in a vertically lifted state. The hooking boom descends to the horizontal position to hook the last car, and pushes the railway car train to complete the scheduling operation.

[0026] The present invention also provides a multi-functional dumper unloading system, including: a dumper and the above-mentioned car pusher. The dumper is a C-shaped dumper, and the rotation center of the dumper coincides with the rotation center of the railway coupler.

[0027] The present invention also provides a method of operating a multi-functional dumper unloading system, including the operation of uncoupling general gondola cars and the operation of non-uncoupling special gondola cars;

[0028] When the dumper unloading system is not operating, the car pusher is in its original position, and both the hook boom and the hooking boom are in a vertically lifted state;

[0033] Step 14: The car puller returns to the operation position, the hooking arm is reset and waits for the next operation of towing the railway gondola car; Repeat steps 11 to 14 until the unloading operation of the entire car body is completed;

[0034] The non - decoupling operation of the special gondola car includes the following steps:

[0035] Step 21: During the non - decoupling operation of the special gondola car, the hook arm of the car puller hooks at the operation position and towes the railway car body forward;

[0036] Step 22: After the hook arm of the car puller tows the railway car body forward by the distance of one gondola car, the railway gondola car is positioned and unloaded in the dumper;

[0037] Step 23: The car puller returns to the operation position, and the hook arm waits for hooking. At this time, arm one is in a horizontal state and arm two is in a vertical state; Repeat steps 21 to 23 until only the last gondola car of the entire car body remains to be unloaded;

[0038] Step 241: When only the last gondola car of the entire car body remains to be unloaded, the car puller returns to the operation position and the hook arm is reset;

[0039] Step 242: When only the last gondola car of the entire car body remains to be unloaded, the hooking arm is connected to the tail end of the last gondola car of the car body and pushes the last gondola car forward; The hooking arm of the car puller pushes the last gondola car of the car body into the dumper for positioning and unloading, and pushes the emptied railway gondola car out of the dumper; The car puller returns to the operation position, and the hook arm and the hooking arm are reset and wait for the next operation of towing the railway gondola car.

[0072] Embodiment 1

[0073] The present invention provides a more economical and concise multi-functional double-arm car pusher, which simultaneously realizes the functions of hook traction and latch hook traction on one car pusher, and respectively realizes the decoupling scheduling operation of general railway open wagons and the non-decoupling scheduling operation of special railway open wagons, thereby reducing the equipment cost of the dumper system and increasing the gross profit margin of the dumper product.

[0074] A multi-functional double-arm car pusher of the present invention includes walking wheels 1, a car body 3, a walking drive unit 4, a hook large arm device, and a hanger large arm device. The walking wheels 1 are installed on both sides of the lower part of the car body 3. The walking drive unit 4 is fixed on the car body 3. The walking drive unit 4 can be connected to the walking wheels 1 through an existing gear mechanism. The walking wheels 1 are driven by the walking drive unit 4 and the gear mechanism to drive the entire car pusher to move. The hook large arm device includes a hook large arm 5 and a first drive device installed on the car body 3. The output end of the first drive device is connected to the hook large arm 5 and is used to drive the hook large arm 5 to rotate reciprocally. The hanger large arm device includes a hanger large arm 2 and a second drive device installed on the car body 3. The output end of the second drive device is connected to the hanger large arm 2 and is used to drive the hanger large arm 2 to rotate reciprocally. In this embodiment, the hanger large arm device can adopt an existing structural form. The hook large arm 5 and the hanger large arm 2 are installed on the same side of the car pusher. In this embodiment, the hanger large arm 2 and the hook large arm 5 can be respectively arranged at the front end and the rear end of the car body 3, that is, in the front and the rear in the traveling direction. The end of the hook large arm 5 is provided with a hook head for realizing the hook traction operation of the car pusher. The end of the hanger large arm 2 is provided with a hanger hook head for realizing the hanger traction operation of the car pusher. Among them, the hanger hook head of the hanger large arm 2 adopts a railway coupler.

[0075] The hook large arm 5 adopts a folding structure and includes an arm body one 51 and an arm body two 52. The first drive device includes a pitch drive unit one 53, a pitch drive unit two 54, a link mechanism one 55, and a link mechanism two 56. One end of the arm body one 51 is hinged to the car body 3. The pitch drive unit one 53 is fixed on the car body 3. The arm body one 51 is connected to the pitch drive unit one 53 through the link mechanism one 55. The pitch drive unit one 53 enables the arm body one 51 to rotate around the hinge point between the arm body one 51 and the car body 3 through the link mechanism one 55.

[0076] The other end of the arm body one 51 is hinged to one end of the arm body two 52. The pitch drive unit two 54 is fixed on the arm body one 51. The arm body two 52 is connected to the pitch drive unit two 54 through the link mechanism two 56. The pitch drive unit two 54 enables the arm body two 52 to rotate around the hinge point between the arm body one 51 and the arm body two 52 through the link mechanism two 56.

[0077] The hook head is a U-shaped groove arranged at the end of the other end of the arm body two 52 for realizing the hook traction operation of the car pusher. The U-shaped groove is adapted to the railway coupler. Among them, the front width a of the arm body two 52 is less than the distance A between two open cars, as Figure 6 shown. At the same time, when the arm body two 52 pitches, the arm body two 52 shall not interfere with the accessories of the railway open car, that is, by reasonably selecting the position of the rotary hinge point of the arm body two 52, the maximum contour rotary radius r of the arm body two 52 is less than the distance R from the accessories of the railway open car to the rotary center of the arm body two 52, as Figure 3 shown.

[0078] It should be noted that when the hook boom 5 is operating, the first boom body 51 is always in a horizontal state, and the second boom body 52 completes the dispatching work of the railway car train through pitching motion. Only when the car puller is not operating, or when the car puller is hooking up, or when the car puller needs to pass through the dumper, the first boom body 51 needs to be in a vertically lifted state.

[0079] Since the dumper needs to accommodate both general gondola cars and special gondola cars, the center of rotation of the dumper needs to coincide with the center of the railway coupler. Therefore, the cross-sectional radius of the dumper is very large, resulting in a particularly long boom for the car puller. The pitching hook of the boom interferes with the accessories of the railway gondola car. Therefore, the hook boom 5 of the present invention is designed as a folding boom to avoid interference.

[0080] In this embodiment, the first pitching drive unit 53 and the second pitching drive unit 54 can adopt a three-in-one motor drive form or a rack and cylinder drive form.

[0081] The present invention also provides a traction dispatching method for a multi-functional double-boom car puller, including the following steps:

[0082] 1. Uncoupling and dumping of general gondola cars:

[0083] 1) The hook boom 5 is lifted, and the first boom body 51 and the second boom body 52 are in a straight line and both are in a vertically lifted state, so that the car puller can pass through the dumper. At this time, the hook boom 5 does not participate in the operation.

[0084] 2) The hooking boom 2 realizes the hooking traction dispatching operation of the railway car train and the gondola car through pitching motion.

[0085] 2. Dumping of special gondola cars without uncoupling:

[0086] 1) During normal cyclic operation, the hooking boom 2 is lifted to the vertical and remains in the lifted state all the time. At this time, the hooking boom 2 does not participate in the operation.

[0087] 2) The first boom body 51 of the hook boom 5 descends to the horizontal position and remains stationary.

[0088] 3) The second boom body 52 of the hook boom 5 realizes the hook traction dispatching operation of the railway car train through pitching motion.

[0089] 4) When only the last car of the railway car train remains to be dumped, the hook boom 5 is lifted, and the first boom body 51 and the second boom body 52 are in a straight line and both are in a vertically lifted state. The hooking boom 2 descends to the horizontal position to hook up with the last car, and pushes the railway car train to complete the dispatching operation.

[0090] Working principle:

[0091] When the general gondola car is uncoupled and dumped, the car dumper needs to pass through the dumper. The hook boom 2 realizes the hook traction dispatching operation of the railway car train and the gondola car through the pitching action, while the latch hook boom 5 does not participate in the work. At this time, the latch hook boom 5 is in the vertical raised state, and the boom body one 51 and the boom body two 52 are in a straight line, as shown in the figure.

[0092] When the special gondola car is not uncoupled and dumped, during the normal cyclic operation, the latch hook boom 5 completes the latch hook traction dispatching operation of the railway car train and the gondola car, and the hook boom 2 does not participate in the operation and remains in the vertical raised state. When only the last car of the entire car train remains undumped, the hook boom 2 descends to the horizontal position to hook the last gondola car and pushes the railway car train to complete the dispatching operation.

[0093] The innovation point of the present invention lies in: realizing the hook traction operation and the latch hook traction operation functions on a single car dumper, respectively realizing the uncoupling dispatching operation of the general railway gondola car and the non-uncoupling dispatching operation of the special railway gondola car. Among them, the latch hook boom adopts the design idea of a folding boom, so that the boom will not interfere with the accessories of the railway gondola car during the pitching process, solving the problem in the prior art that the pitching boom cannot realize the latch hook operation due to interference with the accessories of the railway gondola car.

[0094] After the implementation of the present invention, it can be applied to the dumper projects on the Daqin Line or other ports at home and abroad. It can enable the multi-functional dumper system to save one car dumper, reduce the floor area and investment cost of the dumper system, and improve the gross profit margin of the dumper system.

[0095] The pitching boom of the car dumper in the prior art can only realize the hook operation and tow and uncouple the gondola car, while the latch hook operation of the non-uncoupled gondola car can only be realized by the telescopic boom, and no pitching latch hook boom is provided in the existing double-boom car dumpers. The car dumper of the present invention is provided with a folding pitching latch hook boom, which can simultaneously realize the hook traction and the latch hook traction functions on a single car dumper, and can respectively realize the uncoupling dispatching operation of the general railway gondola car and the non-uncoupling dispatching operation of the special railway gondola car.

[0096] Embodiment 2

[0097] The present invention also provides a more economical and concise multi-functional dumper unloading system and method, which uses a single car dumper to simultaneously realize the uncoupling dispatching operation of the general railway gondola car and the non-uncoupling dispatching operation of the special railway gondola car, thereby reducing the equipment cost of the dumper unloading system and improving the gross profit margin of the dumper product.

[0098] The multi-functional dumper unloading system of the present invention includes a dumper and the above-mentioned car dumper. The dumper is a C-shaped dumper, and the rotation center of the dumper coincides with the rotation center of the railway coupler.

[0099] The present invention also provides a method for operating a multi-functional dumper unloading system, including:

[0100] Step 1: When the dumper car unloading system is not operating, the car pusher 200 is in its original position, and both the hook boom 5 and the hooking boom 2 are in the vertically raised state, as Figure 8 shown;

[0101] Step 2: When performing the decoupling operation on a general gondola car, the hook boom 5 of the car pusher 200 is in the vertically raised state, the hooking boom 2 of the car pusher 200 hooks onto the railway gondola car and pulls the train forward, as Figure 9 shown;

[0102] Step 3: When performing the decoupling operation on a general gondola car, the hooking boom 2 of the car pusher 200 pulls the railway gondola car to be positioned and dumped inside the dumper 100, and pushes the emptied railway car out of the dumper 100, as Figure 10 shown;

[0103] Step 4: When performing the decoupling operation on a general gondola car, the hooking boom 2 of the car pusher 200 pushes the emptied railway car into place, as Figure 11 shown;

[0105] Step 6: When not performing the decoupling operation on a special gondola car, the hook boom 5 of the car pusher 200 hooks at the operating position and pulls the railway train forward, as Figure 13 shown;

[0106] Step 7: When not performing the decoupling operation on a special gondola car, after the hook boom 5 of the car pusher 200 pulls the railway train forward by the distance of one gondola car, it positions and dumps the railway gondola car inside the dumper 100, as Figure 14 shown;

[0107] Step 8: When not performing the decoupling operation on a special gondola car, the car pusher 200 returns to the operating position, and the hook boom 5 waits for hooking. At this time, the first arm body 51 is in the horizontal state and the second arm body 52 is in the vertical state, as Figure 15 shown; repeat steps 6 to 8 until only the last gondola car of the entire train remains undumped;

[0108] Step 9: When only the last gondola car of the entire train remains undumped, the car pusher 200 returns to the operating position and the hook boom 5 resets;

[0109] Step 10: When not performing the decoupling operation on a special gondola car and only the last gondola car of the entire train remains undumped, the hooking boom 2 couples to the last gondola car of the train and pushes the last gondola car forward, as Figure 16As shown; the hook boom 2 of the car puller 200 pushes the last gondola car of the train into the dumper 100 for positioning and dumping, and pushes the emptied railway car out of the dumper 100, as Figure 17 shown; the car puller 200 returns to the working position, the hook engaging boom 5 and the hook boom 2 are reset and wait for the next operation of pulling the railway gondola car.

[0110] Working principle:

[0111] When the general gondola car is decoupled and dumped, the car puller needs to pass through the dumper (the cross-sectional view of the car puller hook operation passing through the dumper is as Figure 18 shown), the hook boom realizes the hook traction dispatching operation of the railway train and the gondola car through the pitching action, while the hook engaging boom does not participate in the work. At this time, the hook engaging boom is in the vertically raised state, and the first arm body and the second arm body are in a straight line.

[0112] When the special gondola car is not decoupled and dumped, during normal cyclic operation, the hook engaging boom is used to complete the hook traction dispatching operation of the railway train, and the hook boom does not participate in the operation and remains in the vertically raised state. When only the last car of the whole train remains undumped, the hook boom descends to the horizontal position to hook the last gondola car and pushes the railway train to complete the dispatching operation.

[0113] It should be noted that when the hook engaging boom is operating, the first arm body is always in the horizontal state, and the second arm body completes the dispatching work of the railway train through the pitching action. Only when the car puller is not operating or the car puller hook is operating and the car puller needs to pass through the dumper, the first arm body needs to be in the vertically raised state.

[0114] Since the dumper needs to take into account both general gondola cars and special gondola cars at the same time, the center of rotation of the dumper needs to coincide with the center of the railway coupler, so the cross-sectional radius of the dumper is very large, resulting in a very long boom of the car puller. The pitching and hooking of the boom interfere with the accessories of the railway gondola car. Therefore, the hook engaging boom is made into a folding boom to avoid interference.

[0115] The innovation of the present invention lies in: through a double-arm car puller with multiple functions, one car puller completes the functions of two car pullers, and respectively realizes the decoupling dispatching operation of general railway gondola cars and the non-decoupling dispatching operation of special railway gondola cars.

[0116] The dumper system of the present invention includes a multi-functional double-arm shunting machine, and only one car puller is required to realize the decoupling operation of general railway gondola cars and the non-decoupling operation of special gondola cars.

[0117] In the prior art, two car pullers are configured for the car dumper unloading system that takes into account both special gondolas and general gondolas at the same time. However, the car dumper unloading system of the present invention only includes one double-arm car puller with a folding pitching hook boom, which realizes the hook traction and hook traction operations on one car puller at the same time, and realizes the decoupling scheduling operation of general railway gondolas and the non-decoupling scheduling operation of special railway gondolas respectively.

[0118] After the implementation of the present invention, it can be applied to the car dumper projects on the Datong-Qinhuangdao line or other ports at home and abroad, reducing the floor area and investment cost of the car dumper system and increasing the gross profit margin of the car dumper system.
