Abstract

An efficient multifunctional reciprocating-type car dumper unloading system comprises a loaded car line and an empty car line. The efficient multifunctional reciprocating-type car dumper unloading system is characterized in that a car stop is arranged in front of a car dumper; the distance between a wheel clamping device and the car dumper is larger than the sum of the length of one section of a loaded car and the lifting length of a big arm of a car puller. A working method of the system comprises the steps that when the car puller pulls the whole column of loaded cars to move forwards, the loaded cars can be directly pulled to the front of the car dumper for column splitting on the condition that the specific locations of the car dumper and a car transfer platform are not considered; when the car dumper is at the original location, and the car transfer platform returns back to the loaded car line, the car puller pulls the loaded cars subjected to column splitting and empty cars, the empty cars are sent to the car transfer platform to be located, and then the loaded cars are sent into the car dumper to be located, so that the car transfer platform acts in advance, the time for waiting for the car transfer platform is shortened, and the unloading efficiency of the car dumper system is improved by 22%.

Description

High-efficiency multi-function unloading system of circular type tipper and method of work thereof
Technical field the invention relates to railway loose unpacked material transportation loading and unloading equipment.
In the current car dumper system technique of background technology, railway loaded vehicle is first located in tippler, then willEmpty wagons is delivered on transfer platform and is located, and causes whole system all waiting for after transfer platform returns loaded vehicle line just enteringThe next circulation of row. The multi-functional formula rigid vehicle tipper dumping system of turning back, treats that tippler and transfer platform existWhen original position, car puller just draws permutation loaded vehicle and advances, and distance travelled long having had a strong impact on of car puller isThe efficiency of unloading of system.
Summary of the invention is the defect that overcomes prior art, and the present invention proposes following technical scheme: oneHigh-efficiency multi-function unloading system of circular type tipper, comprises loaded vehicle line and empty wagons line. Loaded vehicle line and empty wagonsOne side of line is installed transfer platform. Loaded vehicle line one side is provided with tippler, car puller, clip wheel device and car lug.Empty wagons line one side is provided with car puller. Be characterized in: before tippler, place car lug. Clip wheel device with turn overDistance between car machine is greater than the length sum of a joint loaded vehicle and the large arm lifting of car puller. Use this heightImitating multi-functional method of work of turning back formula tipper unloading system is: car puller traction permutation loaded vehicle advancesTime do not consider that tippler and transfer platform particular location can directly draw loaded vehicle to before tippler and separateRow. When tippler returns after loaded vehicle line with transfer platform in position, loaded vehicle and sky after car puller traction off-the-lineCar, first delivers to empty wagons on transfer platform and locates. Again loaded vehicle is delivered in tippler and located.
High-efficiency multi-function unloading system of circular type tipper of the present invention and method of work thereof, owing to turning overIncrease car lug before car machine, the distance between clip wheel device and tippler be greater than a joint loaded vehicle and car puller largeThe length sum of arm lifting, so in the time that car puller traction permutation loaded vehicle advances, can not consider tipplerAnd transfer platform specific works position and directly draw loaded vehicle to before tippler and off-the-line. When tippler is formerPosition and transfer platform return after loaded vehicle line, and loaded vehicle and empty wagons after car puller traction off-the-line, first deliver to empty wagonsOn transfer platform, locate, then loaded vehicle is delivered in tippler and located, transfer platform is moved in advance, reducedWait for the transfer platform time, thereby by car dumper system unload efficiency improve 22%.

In figure: 1, general can decoupling device open-top car row,, 1 ', special not decoupling device open-top car row, 2, clip wheel device,3, decoupling device point i, 3 ', decoupling device point ii, 4, car puller, 5, loaded vehicle line, 6, tippler,7, empty wagons line, 8, transfer platform, 9 car pullers, 10, car lug, 11,1# empty wagons, 12,2Empty wagons, 13,3# loaded vehicle, 14,4# loaded vehicle, 15,5# loaded vehicle, 16,3# empty wagons, 17,4# is heavyCar, 18,5# loaded vehicle, 19,6# loaded vehicle
This high-efficiency multi-function unloading system of circular type tipper of detailed description of the invention, comprises loaded vehicle line5 and empty wagons line 7. One side of loaded vehicle line 5 and empty wagons line 7 is installed transfer platform 8. Loaded vehicle line 5 one sides are establishedThere are tippler 6, car puller 4, clip wheel device 2 and car lug 10. Empty wagons line 7 one sides are provided with car puller 9.It is characterized in that: at the front placement car lug 10 of tippler 6. Distance between clip wheel device 2 and tippler 6From the length sum that is greater than a joint loaded vehicle and car puller 4 large arm liftings. This high-efficiency multi-function Zigzag typeThe method of work of tipper unloading system is: when car puller traction permutation loaded vehicle advances, do not consider tippler6 and transfer platform 8 particular locations, can directly draw loaded vehicle before tippler 6 and carry out off-the-line. WhenTippler 6 in position with 8 times loaded vehicle lines 5 of transfer platform after, car puller 4 draw loaded vehicle after off-the-line andEmpty wagons, directly delivers to empty wagons location on transfer platform 8. Again loaded vehicle is delivered to the interior location of tippler 6.
In technical scheme of the present invention, between clip wheel device 2 and tippler 6, need to meet placement one joint loaded vehicleAnd the required distance of car puller 4 large arm liftings, simultaneously at the front placement car lug 10 of tippler 6, work as gearCar device 10 stops that car puller 4 cannot pass through, and allows car puller in the time that car lug 10 puts down while erecting4 pass through smoothly. Tippler 6 zero-bit and transfer platform 8 during at loaded vehicle line 5 car lug 10 put down and dial carMachine 4 passes through, tippler 6 not zero-bit or transfer platform 8 during not at loaded vehicle line 5 car lug 10 lift resistanceOnly car puller 4 passes through. What, dial no matter under working condition to ensure tippler 6 and transfer platform 8Car machine 4 can directly draw loaded vehicle and be listed as pedestrian's work decoupling device of going forward side by side before tippler 6, saves car puller4 tractions are rearranged and the artificial decoupling device time. When tippler 6 in position with 8 times loaded vehicle lines 5 of transfer platform after,The loaded vehicle that car puller 4 draws after off-the-line is even hung the interior empty wagons of tippler 6, directly empty wagons is delivered to transfer platformLocation on 8, then by the anti-loaded vehicle interior location of tippler 6 of shifting onto, transfer platform 8 is moved in advance, reduceWait for time of transfer platform 8, thereby the car dumper system efficiency of unloading is improved to 22%.
