Description
Technical field
The utility model relates to technical field of diesel locomotive, particularly a kind of combustion engine car weight connection towing gear.
Background technology
Diesel locomotive two-shipper necessarily requires all multi-locomotives to work the tractive force of competence exertion two locomotives simultaneously when heavily joining traction.When multi-locomotive is in low-speed heave-load running under power state, rate request is not high, but tractive force requires comparatively large, therefore, must work by two locomotives simultaneously.Cause two diesel engine of locomotive to be all operated in the relatively high low rotation speed area of fuel oil consumption like this, greatly reduce the operation efficiency of car load, add operation cost.
For realizing low-speed heave-load traction, usually take following two kinds of measures with contact:
1, Locomotive Axle Load is increased, exploitation macro-axis heavy-duty machine car.
2, the locomotive number of axle is increased, exploitation unit eight axle locomotive.
1st kind of measure also exists two shortcomings:
(1) again must build circuit, improve its carrying capacity, but this just needs to drop into substantial contribution.
(2) need to develop the macro-axis heavy-duty machine car being applicable to heavy traction.Up to the present, domestic still do not have actual product, only that preliminary exploration has been done with reference to companies such as the U.S. GE, EMD by some institutes and indivedual enterprise, need to restudy and development of new locomotive, particularly the parts such as the wheel of locomotive running gear part, axletree, bearing, pendulum spring, draw gear and high pulling torque traction electric machine.
2nd kind of measure also exists two shortcomings:
(1) locomotive running gear part-structure is complicated, and maintenance cost is high.
(2) locomotive oad is comparatively large, cannot meet domestic vehicle gauge of the locomotive, more cannot meet state's vehicle gauge of the locomotive such as Africa, South America, Australia.
Therefore, our company have developed a kind of combustion engine car weight connection towing gear again.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of combustion engine car weight to join towing gear.
The technical solution adopted in the utility model is such:
A kind of combustion engine car weight connection towing gear, comprise two cover locomotive main driving systems, often overlap locomotive main driving system and comprise driving engine, pulling electric generator, distillation plant, traction convertor, rheostatic brake current transformer, AuCT, traction electric machine, rheostatic brake device, isolating transformer, filter, auxiliary consumer, described electrical generator, pulling electric generator, rectifying device, first DC contactor connects successively, locomotive double heading DC bus and locomotive DC bus two branch roads are divided into after first DC contactor, described locomotive DC bus there are three branch roads, article one, be connected with traction electric machine by traction convertor, article one, pass through AuCT successively, isolating transformer, filter is connected with auxiliary consumer, article one, be connected with rheostatic brake device by rheostatic brake current transformer, the locomotive double heading DC bus of described two cover locomotive main driving systems, cross connection between locomotive DC bus.
As preferably, often overlapping in locomotive main driving system, described locomotive double heading DC bus is provided with the second DC contactor.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, on existing line, utilize the locomotive of the parts manufacture of the existing maturation of locomotive to realize heavy traction, substantial contribution need not be dropped into and build heavy-haul line, also do not need again development of new locomotive component and mechanical development novel load-carrying hauling engine.
2, according to actual traction requirements, the mode of operation of multi-locomotive can be selected arbitrarily, improve the operation grade of whole train, reduce user's operation cost.
3, when multi-locomotive needs low-speed heave-load to draw, only can select an engine operation, all the other driving engines do not work; When multi-locomotive needs high-speed overload to draw, two driving engines can be selected all to devote oneself to work, improve the carrying capacity of whole train.No matter be low-speed heave-load traction or high-speed overload traction, driving engine is all operated in economical operation section.

Mark in figure: DE is driving engine, M-G is pulling electric generator, KM is main switch, RU is rectifying device, and KMDC1 is the first DC contactor, and KMDC2 is the second DC contactor, DC-M locomotive double heading DC bus, DC-C is locomotive DC bus, and MU1 first heavily joins tractor, and MU2 second heavily joins tractor, M-INV is traction convertor, TM is traction electric machine, and P-INV is rheostatic brake current transformer, and RB is rheostatic brake device, A-INV is AuCT, TU is isolating transformer, and FU is filter, and AM is auxiliary consumer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment:
As shown in Figure 1, a kind of combustion engine car weight connection towing gear, comprises two cover locomotive main driving systems, often overlaps locomotive main driving system and comprise driving engine DE, pulling electric generator M-G, distillation plant RU, traction convertor M-INV, rheostatic brake current transformer P-INV, AuCT A-INV, traction electric machine TM, rheostatic brake device RB, isolating transformer TU, filter FU, auxiliary consumer AM, described electrical generator DE, pulling electric generator M-G, rectifying device RU, first DC contactor KMDC1 connects successively, locomotive double heading DC bus DC-M and locomotive DC bus DC-C two branch roads are divided into after first DC contactor KMDC1, described locomotive DC bus DC-C there are three branch roads, article one, be connected with traction electric machine TM by traction convertor M-INV, one successively by AuCT A-INV, isolating transformer TU, filter FU is connected with auxiliary consumer AM, and one is connected with rheostatic brake device RB by rheostatic brake current transformer P-INV, the locomotive double heading DC bus DC-M of described two cover locomotive main driving systems, cross connection between locomotive DC bus DC-C, often overlapping in locomotive main driving system, described locomotive double heading DC bus DC-M is provided with the second DC contactor KMDC2.
Driving engine DE drives pulling electric generator M-G to produce three plase alternating current, provides stable intermediate dc power supply by elements such as the rectifier diode of rectifying device RU and high-voltage capacitances.Then, locomotive DC bus is provided the three plase alternating current of variable-frequency variable-voltage to traction electric machine TM by traction invertor M-INV, by AuCT A-INV for auxiliary consumer AM various on locomotive provides power supply.When locomotive brake, traction electric machine TM is powered to locomotive DC bus DC-C by traction invertor M-INV, can be used for auxiliary consumer AM, and unnecessary power consumption is on rheostatic brake device RB.
When multi-locomotive low-speed heave-load draws, disconnect the first DC contactor KMDC1 of other locomotive main driving systems and excise driving engine DE, only retaining the driving engine DE of a set of locomotive main driving system.And powered to all the other multi-locomotive traction convertor M-INV and traction electric machine TM and relevant auxiliary consumer AM by DC bus DC-M, the DC contactor KMDC2, adaptor union MUL etc. of locomotive double heading.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
