It sets and is installed in 1 lower part of vehicle body with spare cleaning plant, apparatus for baking is mounted on 1 lower part front end of vehicle body, the apparatus for baking
It is made of heating tube 8 and reflector 9, reflector 9 is lower open, and heating tube 8 is mounted on inside reflector 9, and reflector 9 is used for will
All heats are reflected on roadmarking, improve the efficiency of baking roadmarking, while mounted heating tube 8 and road surface
Graticule is not directly contacted with, and prevents the graticule of baking after-tack to be attached in heating tube 8, the bottom of heating tube 8 is between graticule
Distance should be in 0.5cm between 5cm, to guarantee be unlikely to have too many heat loss in air；In cleaning roadmarking
When, apparatus for baking works at first, roadmarking is baked soft, and perching knife 10 is mounted on apparatus for baking rear portion, institute immediately following apparatus for baking
State that perching knife 10 is designed as arc shape and its width is wider than marking width, to guarantee all to scoop up roadmarking, 10 knot of perching knife
Structure is divided into two parts, and part 18 is made of metal on perching knife, and part 17 is also made of metal under perching knife but it is internally provided with electricity
Heated filament, heating wire are mainly used for heating the blade 19 of part 17 under perching knife, under perching knife 17 tangential of part in road surface, design
17 tangential of part is provided to preferably scoop up roadmarking in road surface under heating wire and perching knife.
After roadmarking is scooped up, part 18 on perching knife can be moved to and assembled, scrap wire collection device is mounted on perching knife 10
Two sides, as shown in Figures 2 to 5, the scrap wire collection device are made of hydraulic column 14, scrap wire plate 15 and collecting box 4, scrap wire plate 15
Side is fixedly mounted on hydraulic column 14, is installed along with vehicle across perching knife 10 between hydraulic column 14, scrap wire plate 15 and collecting box 4
1 lower part of body, 4 opened upper end of collecting box, that side installed against perching knife 10 is provided with a polygonal hole 16, described
15 its underpart of scrap wire plate is can be with the camber line that part 18 matches on perching knife, 16 its underpart of polygonal hole being arranged on collecting box 4
It also is similar camber line, scrap wire plate 15 can pass in and out the polygonal hole 16 on collecting box 4 under the action of hydraulic column 14, when on perching knife
When the roadmarking that part 18 is assembled is more, the work of hydraulic column 14 drives scrap wire plate 15 to move to collecting box 4, and scrap wire plate 15 pushes
Polygonal hole 16 of the scrap wire 20 on collecting box 4 on perching knife 10 moves, and scrap wire 20 is pushed into collecting box 4 by polygonal hole 16
In, 15 lower part of scrap wire plate closely installed on perching knife by part 18, and scrap wire plate 15 does not contact part 17 under perching knife, to guarantee scrap wire
Plate 15 does not interfere with the work of perching knife 10 during exercise, while can guarantee that perching knife 10 will not influence scrap wire plate when travelling forward yet
15 movements, so that scrap wire plate 15 can pass in and out collecting box 4 under the action of hydraulic column 14.
The spare cleaning plant is mounted on the rear end of 1 lower part of vehicle body, and in the case where apparatus for baking and perching knife 10 are acted on, there are also not
Clean roadmarking is cleared up by spare cleaning plant.The spare cleaning plant is by motor 2, reduction gearbox 3, circle
Disk wire brush 12 and color sensor 11 form, and motor 2 drives wire wheel brush 12 to rotate by reduction gearbox 3, inside reduction gearbox 3
It is driven by gear 13, color sensor 11 is used for information feedback, and motor 2 and reduction gearbox 3 are mounted on vehicle body 1, disk
Wire brush 12 and color sensor 11 are mounted on 1 lower part of vehicle body, and color sensor 11 is mounted on 12 front end of wire wheel brush, only
When detecting that roadmarking is not clean by color sensor 11, which just drives wire wheel brush 12 to rotate, to road
Marking lines are cleaned again, which can be reduced well to road using wire wheel brush 12 without the use of traditional mill
Abrasion, while roadmarking is after baking, the cleaning effect for the more traditional mill of effect for using wire brush to carry out subsequent cleaning
Fruit will get well.
1 lower part of vehicle body is symmetrically installed with wheel 6, and 1 lower part surrounding of vehicle body is provided with shield plate 7, in vehicle body 1
The shield plate 7 of lower part setting can block scrap wire 20 and sputter to come to a certain extent.
According to a kind of roadmarking shown in above-mentioned Fig. 1 to Fig. 5, is made except line vehicle, when in use, operator is only for the device
It is that apparatus for baking, scrap wire collection device and the power supply of spare cleaning plant, the device can work normally that battery 5, which need to be allowed, is operated
Personnel make to be aligned roadmarking to be treated except 1 middle of line vehicle vehicle body by wheel 6, and apparatus for baking work will be to needing to locate
The roadmarking of reason is toasted, and operator will slowly push forward except line vehicle, and when travelling forward except line vehicle, perching knife 10 can be incited somebody to action
The roadmarking just toasted scoops up, and when the graticule scooped up is more, the start-up operation of hydraulic column 14 makes scrap wire plate 15 push scrap wire
20 move to collecting box 4, and scrap wire 20 is pushed into collecting box 4, and after scrap wire 20 is pushed into collecting box 4, scrap wire plate 15, which is withdrawn, to be restored to
Origin-location, after roadmarking is by apparatus for baking and perching knife 10, if roadmarking is not clean, in color sensor
After 11 detect information, motor 2 will drive wire wheel brush 12 to rotate by reduction gearbox 3, will be clean to roadmarking,
In 1 lower part of vehicle body, the shield plate 7 of setting can block scrap wire 20 and sputter to come to a certain extent, clean out in roadmarking
Later, the scrap wire 20 collected in collecting box 4 is poured into dustbin.
Technology contents and technical characteristic of the invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and be this patent Shen
Please claim covered.
