Description

Medium-and low-speed maglev engineering working vehicle

Technical field

This utility model relates to rail vehicle technical field, especially for the working truck that medium-and low-speed maglev Rail Transit System is overhauled。

Background technology

In medium-and low-speed maglev traffic system, consider from reasons such as construction cost, technology requirements, the major part system such as track, conductor rail is all mounted on elevated bridge, and the equipment such as track, conductor rail is all belonging to, and volume is relatively big, the equipment of heavier-weight, break down when needing repairing when elevated bridge insufficient space, it is all not thing very easily, is now accomplished by being equipped with engineering working vehicle and has assisted the work being correlated with。

On the other hand owing to circuit whole process is overhead, when winter snowy weather occurring, accumulated snow is had above track, even ice condition occurs, and the suspension of medium-and low-speed maglev vehicle and to walk provisional capital be that the reactive aluminum plate with the F type rail on track and F type track surface is associated, if track will affect the normal operation of medium-and low-speed maglev vehicle with thick accumulated snow or when having ice to occur。Furthermore, thick accumulated snow occurs in the middle of sleeper, can not get clearing up timely, the process that maglev vehicle runs can be rolled into underbody, add microthermal climate and can freeze all kinds of big parts of underbody, vehicle being caused damage, also directly influences the operation of maglev vehicle, this is also that medium-and low-speed maglev system needs engineering truck to assist the reason of operation。

Middle low speed magnetic suspension track traffic upkeep operation car (hereinafter referred to as: Operation Van), it is independently travel on the upkeep operation car on magnetic-levitation, during this car operation, the power supply on track circuit is not powered, and its power resources are Diesel engines。

Detailed description of the invention

In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail。

Refer to Fig. 1, Fig. 2, Fig. 1 is the structural representation of a kind of detailed description of the invention of this utility model provided medium-and low-speed maglev engineering working vehicle；Fig. 2 is the partial schematic diagram of guiding mechanism shown in Fig. 1。

As shown in the figure, in a kind of detailed description of the invention, this utility model provided medium-and low-speed maglev engineering working vehicle bogie, with reference to railway operation vehicle, uses aluminum alloy wheel to realizing traveling, it is considered to F type track material is Q235B, the physical property of track material is extremely common, the load of car load carrying steel wheel is calculated, it is determined that car load with six single-axle bogies 1, each turns to that to set up one group of wheel right from complete vehicle weight analyzing, i.e. two driving wheels 2, car load amounts to 12 driving wheels 2。

, draw bar etc. is made up of by each single-axle bogie 1 framework, suspension, axle box, side bearing, road wheel, adopts single shaft six bogie, it is possible to achieve the turning in the only small situation of radius, solves the problem that magnetic flotation line road turning radius is little。

It is F rail two siding track shank position owing to this Operation Van can run track, consider the traveling particularity that track exists, be available for running track width and be only 120mm, therefore travelling wheel width specification is relatively special, the factors such as curved crossed by the installation and the vehicle that consider actual regulation, and actual wheel width is designed as 100mm。Owing to tool car car load rate request is not high, it is only about 30km/h the most at a high speed, much smaller than the railway universal machine speed of service, corresponding contents with reference to TBT1010-2005 " rail truck is taken turns pattern and basic size ", preliminary selected Type B wheel is to steel wheel as Selection and Design basis, and it takes turns external diameter is 840mm (see Fig. 5)。

12 aluminum alloy wheels being provided with wheel-side motor in this Operation Van are traction drive wheel; boss material is 6082-T651 alloy aluminum; for ensureing the protection to rail, it is considered to other material softer than Q235B with rail contact ring edge, as: H62, DT9 and the composite that some are special。

Each single-axle bogie 1 is respectively equipped with guiding mechanism, and guiding mechanism includes the directive wheel 3 and the spring 4 that are symmetrically arranged a pair, under the elastic force effect of spring 4, directive wheel 3 is pressed on the lateral surface of F rail two siding track shank position, during design, this spring 4 adopts greater stiffness, to guarantee that guiding is accurately。

Guiding mechanism is provided with the support 5 downwardly extended from single-axle bogie 1 both sides, directive wheel 3 is installed on support 5 by upper cantilever 6 and lower cantalever 7, being respectively equipped with on upper cantilever 6 and lower cantalever 7 in oblong directive wheel axis hole 8, directive wheel 3 can move along Operation Van's width。

Specifically, the spring 4 of each directive wheel 3 includes upper spring and the lower spring of lateral arrangement, upper spring and lower spring are separately mounted between support 5 and directive wheel rotating shaft in telescopic throwout sleeve 11, from the rotating shaft top and bottom of directive wheel 3, directive wheel is supported, directive wheel 3 in inverse-T-shaped, be divided into road wheel face portion and be positioned at the card rim portion of bottom on longitudinal section。

Arranging two groups of guiding mechanisms in single leading truck mechanism, i.e. four directive wheels 3, each two of left and right, to guarantee the guide function of the positive reverse driving of vehicle。

During tool car straight-line travelling, the lateral force that directive wheel 3 produces with F type track is relatively small, and directive wheel 3 is close to rail spigot surface under the effect of preloading spring 4, and then leads reliably；Operating mode when vehicle is crossed curved, now, produces bigger side force outside outside directive wheel 3 and track, and inner side directive wheel compresses preloading spring 4 under this active force, and outside directive wheel 3 now discharges spring 4 pretightning force, and then also can realize good guide effect。

Refer to Fig. 3, Fig. 4, Fig. 3 is the curved schematic diagram of the mistake of bogie shown in Fig. 1；Fig. 4 is the curved shifting amount schematic diagram of the mistake of bogie shown in Fig. 1。

As shown in the figure, six single-axle bogies 1 are combined by TRUCK, realize the traction to car body, support, damping and prevent rollover function, the spacing of bogie is designed as 1.2m, count from front to back, compartment 9 is provided with and the first single-axle bogie, 3rd single-axle bogie, the towing pin of the 4th single-axle bogie and the 6th single-axle bogie slides laterally the horizontal concrete chute 10 of connection, that is, cross curved time first, three, four, six single-axle bogies can slide laterally, crossed curved shifting amount schematic diagram from six bogies to analyze: when crossing curved, bogie is 57.463mm relative to the maximum slippage of car body。

In actual use, traction drive wheel can adopt the pattern that rubber wheel and aluminum alloy wheel exchange, and when rainy day or snow sky, rubber wheel changes into aluminum alloy wheel, generally uses rubber wheel, it is possible to achieve the protection to track F rail。

Refer to Fig. 6, Fig. 7, Fig. 6 is the structural representation of a kind of detailed description of the invention of snow removing deicing device；Fig. 7 is the top view of snow removing deicing device shown in Fig. 6。

As it can be seen, the medium-and low-speed maglev engineering working vehicle with snow removing ice-melt function provided by the utility model, being provided with snow removing deicing device 20, it is divided into following three parts:
