The present invention is described in further detail below in conjunction with the accompanying drawings.
The present invention formula track that switches tracks automatically is removed obstacles and the overall structure of diagnostic device is as depicted in figs. 1 and 2, and the present invention is root
The new technical solution proposed according to the adverse circumstances that rail is runed for a long time.
The cigarette butt that passenger is thrown near platform, the house refuses such as packaging bag are innumerable, affect environment by bus and
Traffic safety, barrier clearing device then efficiently solve the problems, such as this, and part of removing obstacles is using the high-power air-flow conveying wind of front two rows
Machine carry out to without how near track rubbish cleaning, while increase bottom cleaning brush device, high-pressure and low-pressure flushing device is made into one
Step cleaning guarantees that the deposits such as house refuse, dregs and mud are by high-efficiency cleaning near track.
Rail diagnosis of partial controls track detection device using traversing and lifting hydraulic cylinder, and track detecting includes taking the photograph
As head captured in real-time system, inclination angle and displacement sensor system, track analysis on cracks detection system.
The not parking system that switches tracks is realized using the spacing of hydraulic cylinder control left and right rail wheel from broad gauge auto-changing to narrow
Rail.
1, automatic track exchanging device:
The not parking system that switches tracks is realized using the spacing of hydraulic cylinder control left and right rail wheel from broad gauge auto-changing to narrow
Rail.As shown in Figure 3.
As shown in Figure 3,4, automatic track exchanging device is mainly by rail wheel 10, mandrel 11, feather key 12, two sides telescopic hydraulic bar

At the area of gauge difference or state boundary, the device will carry out it is not parking switch tracks, due to track diagnostic device
Close to two sides rail, so must assure that the spacing of two siding track diagnostic devices is identical as the gauge after switching tracks.Two sides interorbital
Away from substantially there is 1500mm, traverse displacement unit uses two-way hydraulic cylinder, and control slider frame moves left and right；Using linear guide, main benefit
Movement is generated in linear guide with guide rail slide block, while guide rail slide block uses ball bearing type curtain rail sliding block, ball bearing type curtain rail sliding block
Slipping phenomenon will not be generated, it can be achieved that high accuracy positioning, coefficient of friction is minimum and manufacture and maintenance are easier；Using four
A small slide block works at the same time, and improves integral rigidity and load, while it is unbalance to avoid front and back to increase counterweight.Peace by traverse displacement unit
Equipped with locking mechanism, avoiding device have in the process of running it is biggish impact and cause to position it is unreliable.Vertical hydraulic cylinder is flexible
The up and down motion of entire track diagnostic device is driven, if not needing the section diagnosed to track, track detecting part can be made
It is detached from rail.
Track detecting includes camera captured in real-time system, inclination angle and displacement sensor system, the detection of track analysis on cracks
System.Camera captured in real-time system includes rear portion photographic device and LED illumination lamp, can captured in real-time orbit picture；Inclination angle and
Displacement sensor system includes obliquity sensor and displacement sensor, and obliquity sensor can the gradient of real-time monitoring rail, position
Displacement sensor can real-time monitoring rail spacing；Track analysis on cracks detection system includes monitoring ultrasonic instrument and display.Together
When, bottom steamboat generates minimum friction close to rail, avoids generating big impact on the way in operation.

Environment and traffic safety, barrier clearing device then efficiently solve the problems, such as this by bus.As shown in Figure 9.
As shown in figure 12, air-flow inhales sweeping device mainly by front two rows blower 22, motor 23, absorbs channel 24 and can be rotated
The composition such as plate 25.Motor 23 is connected by bolts on the shelf on 22 side of blower, and blower 22 is pacified in the form that bolt-connection couples
On the cavity of intermediate rotatable plate.Rotatable plate 25 is movably attached in cavity by central axis, when sucking garbage weight
Reaching a certain level will be flipped, and it is right that absorption channel 24 is mounted on corresponding blower 22 in the form of bolt-connection
Face, lower end extend between car body and guide rail.
As shown in figure 13, refuse compressor is mainly by dustbin 26, lifting cylinder 27, pressing plate 28, dustbin guide rail 29
It is formed with mechanical arm 30 Deng.27 top of lifting cylinder is mounted on car body upper surface, lower part and pressing plate 28 in the form of bolt-connection
Weld together, mechanical arm 30 is installed on the car body, and the track groove of dustbin 26 is mounted on dustbin guide rail 29, and dustbin is led
Rail 29 is by welding on the car body.
As shown in Figure 10 and Figure 11, the cleaning of railway is usually based on jetting type automation.It is equipped with and disturbs in water tank 38
Flowing plate 31, high-low pressure spray equipment are made of low pressure spray head 32, high-pressure nozzle 33, valve 34 and spoiler water tank 38.Valve 34 with it is low
Spray head 32, high-pressure nozzle 33 and spoiler water tank 38 is pressed to install in the form of bolt-connection respectively, low pressure spray head 32, high-pressure nozzle
33 by car body overhead notch through on vehicle bottom rail road.
As shown in Figure 10, bottom turns to brush and mainly be made of hairbrush 35, air motor 36.Hairbrush 35 and air motor 36 are installed
In on fixed frame 37.When work, air motor 36 is rotated 360 ° with electric brush 35.
Remove obstacles part using the high-power air-flow conveying fan of front two rows carry out to without how near track rubbish cleaning, rubbish
Rubbish enters rotatable plate by pipeline due to the sucking action of larger air-flow.When debris accumulation to a certain extent when, rubbish due to
Self weight, causes rotatable plate to rotate, falls into dustbin.If the rubbish in dustbin is excessive, dress is compressed in the lifting on top
The area occupied of rubbish can be reduced by the lifting compressed garbage of hydraulic cylinder by setting.If the rubbish in dustbin has been expired, bottom
Four big hydraulic lifts whole device can be lifted, be adjusted at height identical as platform plane, manipulator can be by rubbish
Cabinet pushes platform to, and platform cleanup crew only needs in time to clear up garbage box, at the same be also convenient for device maintenance and its
He effectively acts on.Rail obstacle clearing device is further equipped with bottom cleaning brush device and high-pressure and low-pressure flushing device, guarantees that track is attached
The deposits such as nearly house refuse, dregs and mud are by high-efficiency cleaning；Water tank is equipped with spoiler, since whole device is being come sometimes
It returns that the speed transported on the way is larger, then water tank will fully consider the percussion of water flow, is equipped with spoiler inside water tank to subtract
Inertia impact of the water to cabinet in few water tank.
In conclusion the present invention relates to a kind of high-speed railway without how track remove obstacles and diagnostic techniques, while it is poor in gauge
At different area or state boundary, which may be implemented the function that switches tracks automatically.Diagnostic device is located at rear portion, if necessary can be with
The diagnosis to rail is carried out by traversing, the lifting of hydraulic device, plays the purpose of real-time monitoring rail；During barrier clearing device is located at
Portion, can be carried out if necessary by high-power air-flow conveying fan to without how near track rubbish cleaning.The present invention is not to
Closed subway is without how track is removed obstacles and diagnosed and is equally applicable.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention.It is all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
