Brief description of the drawings
Fig. 1 is Tunnel testing bassinet structure schematic diagram.
In figure, 1 is railcar unit, and 2 be insulation wheel, and 3 be located lateral wheel group.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in figure 1,
A kind of Tunnel testing car, including vehicle frame, located lateral wheel group 3, the vehicle frame include multiple railcar units 1, institute
The insulation wheel 2 stated on the multiple beading of railcar unit 1 connections, the multiple railcar unit 1 is integrated with grating encoder,
Characterized in that, the located lateral wheel group 3 is only installed on a track, the located lateral wheel group 3 is in a railcar
The installation group number of unit 1 is 2 groups, and the located lateral wheel group 3 is made up of 2 single-wheels, and 2 single-wheels are located at the two of a track respectively
The side of side, the single-wheel and track is in rolling contact, and the axle of the single-wheel is vertical with orbit plane, it is ensured that railcar unit 1 is transported
The contacts side surfaces of single-wheel all the time with track when dynamic, the insulation of railcar unit 1 number of wheel 2 is 2n or 2n+1, wherein, n is
The natural number being not zero, the tread of insulation wheel 2 of the railcar unit 1 is plane, and located lateral is carried out about without wheel rim
Beam, the accurate distance value of railcar traveling can be obtained by being multiplied by wheel circumference with the angle turned over.The located lateral wheel
Group 3 single-wheel section be " V " shape, it is ensured that when track side surfaces have greasy dirt and soil, located lateral wheel group 3 still with track
Side plane is in close contact.The located lateral wheel group 3 be separately mounted to the car body lower surface of a railcar unit 1 front portion and
Rear portion, if the insulation number of wheel 2 of railcar unit 1 is 2n, 2 groups of located lateral wheel groups 3 are separately mounted to the car of railcar unit 1
The left and right sides of body lower surface, if the insulation number of wheel 2 of railcar unit 1 is 2n+1,2 groups of located lateral wheel groups 3 install in-orbit
The car body lower surface of road car unit 1 has the side of n+1 insulation wheel 2.It is located in 2 single-wheels of the located lateral wheel group 3
Single-wheel support frame on the inside of track carries out rigidity in the vertical direction of direct of travel and direct of travel with railcar unit 1 and connected
Connect, it is firm in direct of travel with railcar unit 1 that the single-wheel on the outside of track is located in 2 single-wheels of the located lateral wheel group 3
Property connection, be elastic connection in the direction vertical with direct of travel, wherein, refer to the vehicle wheel of railcar unit 1 on the inside of the track
Edge side.If the insulation number of wheel 2 of railcar unit 1 is 2n+1, the car body lower surface of railcar unit 1 is not installed laterally fixed
The side of position wheel group 3 is not provided with the lateral confinement structure conflicted with located lateral wheel group 3.
During Tunnel testing car is advanced in tunnel, tunnel is obtained by the detection means on Tunnel testing car
Interior image information.The accurate distance value of railcar traveling, this hair can be obtained by being multiplied by wheel circumference with the angle turned over
The wheel tread that the Tunnel testing car of bright offer is used be plane, wheel circumference will not as taper tread or curved surface tread because
The perimeter change to be different from rail contact point, because wheel tread is the wheel of plane, no matter whether its track crawls, girth
It is always constant.As long as ensureing that vehicle wheel rotation angle is that can obtain a relatively accurate travel distance value.
During Tunnel testing garage enters, in horizontal position error essentially from the random serpentine path of Tunnel testing car
Change, therefore, the present invention eliminate snake with locating wheel group.Locating wheel group is to be rigidly connected with car body two-dimensional directional by one
Nearside wheel and one advance with car body along rail to being rigidly connected, outboard wheel that the transverse elasticity vertical with track is connected composition.
The elastic force for pointing to nearside wheel by outboard wheel makes inner side wheel tread be contacted all the time with rail medial surface.Nearside wheel and outboard wheel and steel
It is rolling friction contact between rail.The rotation of nearside wheel and outboard wheel itself passes through bearing arrangement.
Tunnel testing car neutralizes relative position horizontal with track when traveling stops due to the presence of locating wheel group advancing
With consistency, the complexity of the data in the tunnel image procossing in later stage is reduced.
