Referring to Fig. 2, Fig. 4 and Fig. 6, guard rail cleaning machine structure 5 includes braced frame 42 is rotationally connected with by bearing several
Rotating roller 51 and the conveyer belt 52 on the outside of rotating roller 51, the lateral wall of braced frame 42 have been bolted for driving
The driving motor 54 that dynamic rotating roller 51 rotates；And cleaning layer is provided with by velcro fastener 6 along its length on conveyer belt 52
53, velcro fastener 6 includes the nylon hook band 61 cemented on conveyer belt 52 and cements in the nylon velvet band 62 on cleaning layer 53, is led to
Adhering to each other for nylon hook band 61 and nylon velvet band 62 is crossed, so that cleaning layer 53 is fixed on conveyer belt 52；And braced frame
42 upper end is fixed with high-pressure nozzle 422 by screw, and high-pressure nozzle 422 is connected by pipeline with water storage tank 2；In cleaning guardrail
When, two braced frames 42 are located at the two sides of guardrail, and driving motor 54 starts, and drive rotating roller 51 to rotate, rotating roller 51
Transmission belt is driven to rotate in the vertical direction, so that cleaning layer 53 is driven to rotate, meanwhile, the water in water storage tank 2 is in high-pressure hydraulic pump
Under the action of, it is ejected on guardrail and cleaning layer 53 through pipeline from high-pressure nozzle 422, in this way, cleaning layer 53 brushes guardrail
It washes.
Referring to Fig. 4 and Fig. 6, cleaning layer 53 includes bottom cloth layer 531 and several hairs uniformly distributed along the length direction of bottom cloth layer 531
Brush layer 532, bottom cloth layer 531 are made of cotton, can effectively remove the dust on guardrail, and hairbrush layer 532 glues on guardrail for clearing up
Attached stain.
Referring to Fig. 7, the both ends of braced frame 42 are provided with extension board 423, are turned between two extension boards 423 by bearing
Dynamic to be connected with rotation axis 4231, the lateral wall of rotation axis 4231 is enclosed with water-absorbing sponge, water-absorbing sponge as water absorption layer 4232, when
After the completion of cleaning layer 53 cleans guardrail, water-absorbing sponge rolls on the lateral wall of guardrail, so that remaining moisture absorption be fallen.
Referring to Fig.1 and Fig. 8, the inner sidewall of holding chamber 11 has been screwed several blow-dry devices 9, blow-dry device 9 by
Fan frame and fan composition, and rotated by motor-driven fan, to accelerate air in holding chamber 11 to blowing in holding chamber 11
Flowing, when descending mechanism 3, supporting mechanism 4 and guard rail cleaning machine structure 5 are located at holding chamber 11, to accelerate residual in said mechanism
The moisture stayed distributes.
Working principle is as follows:
When that need to clear up guardrail, firstly, pedestal 31 is pulled out out of holding chamber 11, when hydraulic cylinder 32 is fully located at placement
When 11 outside of room, start hydraulic cylinder 32, hydraulic cylinder 32 drives crossbeam 411 to move up, and crossbeam 411 drives support rod 41 to moving up
Dynamic, support rod 41 drives braced frame 42 to move up, at this time moving body 1 so that braced frame 42 be located at guardrail just on
Then side drives braced frame 42 to move down, so that two groups of braced frames 42 are located at the two of guardrail by hydraulic cylinder 32
Side；Then start cylinder 412, cylinder 412 drives sliding sleeve 421 mobile, and sliding sleeve 421 drives braced frame 42 mobile, works as support frame
When frame 42 is mobile with driven triggering device 7, making leaf spring 72 abuts to guardrail, and deformation occurs for making leaf spring 72, and contact-making switch 71 detects
Pressure signal, and cylinder 412 is transmitted a signal to, cylinder 412 stops immediately, at this point, the guard rail cleaning machine in braced frame 42
Structure 5 touches guardrail；Then, start driving motor 54, driving drives rotating roller 51 to rotate, and rotating roller 51 drives transmission belt perpendicular
Histogram is rotated up, so that cleaning layer 53 is driven to rotate, meanwhile, the water in water storage tank 2 is under the action of high-pressure hydraulic pump, through pipeline
It is ejected on guardrail and cleaning layer 53 from high-pressure nozzle 422, in this way, cleaning layer 53 scrubs guardrail, then, moving body
1, into normal operation.
When operation completion, guard rail cleaning machine structure 5, supporting mechanism 4 and elevating mechanism 3 need to be recovered in holding chamber 11, by
In withdrawal operation with the operation of releasing said mechanism just on the contrary, therefore be not specifically addressed herein；After withdrawal, pass through fan
To blowing in holding chamber 11, accelerate the circulation of air in holding chamber 11, so that remaining moisture is rapidly losing in said mechanism.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
