In order to realize the rotation of the roller 15, a crank is arranged at the right end part of the roller 15.
The cross section of hollow tube 1, standpipe 2, montant 3, polished rod 8, first sleeve 9 and second sleeve 24 is the rectangle, is connected with high-pressure water source on the shower nozzle 13, and there is the fender dish at the upper end of polished rod 8, and the power cord of electro-magnet 10 passes in the polished rod 8.
The specific working process of the invention is as follows: when the device is used, the device is pushed into the position right above a guardrail along the length direction of the guardrail, before the device is pushed, an electric telescopic rod 23 is driven to extend to realize the integral lifting of a cleaning device, the electric telescopic rod 23 is connected to a mobile power supply, the lower end of a second sleeve 24 is arranged above the upper ends of vertical pipes 2, a herringbone support 22 enables two second sleeves 24 to respectively correspond to two vertical pipes 2 of a group of guardrails, the electric telescopic rod 23 is driven to enable the herringbone support 22 to descend and enable the two sleeves to be sleeved at the upper ends of the two vertical pipes 2, a rotating rod 27 is rotated to enable the rotating rod 27 to keep a vertical shape and be clamped in a C-shaped groove 28, a polished rod 8 keeps a vertical shape at the moment, a roller 15 is rotated to enable a first rope 16 to be wound, the plurality of polished rods 8 to move downwards and enable intervals to exist between the first sleeves 9 with fixed lower end parts and the upper ends of the vertical pipes 3, and a blocking rod is inserted, the opening 5 is not corresponding to the clamping groove 6, and the vertical rod 3 is clamped in the hollow tube 1 under the blocking effect of the two baffles 4.
When cleaning is needed, the crank is loosened to enable the plurality of polish rods 8 to move downwards under the reset action of the first pressure spring 17, the first sleeve 9 fixed at the lower ends of the plurality of polish rods 8 is buckled at the upper end of the corresponding vertical rod 3, the through pipe presses the main switch 29 to enable the plurality of electromagnets 10 to be electrified and to be adsorbed to the plurality of vertical rods 3, so that the polish rods 8 are rigidly connected with the corresponding vertical rods 3, the L-shaped rod 25 is pressed after connection is completed, the lower end of the L-shaped rod 25 extrudes the compression rod 19 and the compression rod 19 moves downwards, in the process, the second pressure spring 20 is compressed and has a rebound tendency and elastic potential energy, when the compression rod 19 moves downwards, the two second ropes 21 are driven to tighten, at the moment, the second ropes 21 tighten the baffle 4 to pull rightwards, the baffle 4 moves rightwards, in the process, the tension spring 18 is stretched and has a rebound tendency and elastic potential energy, and simultaneously, the notches 5 on the baffle 4 correspond to the clamping grooves 6 on the vertical rods 3, baffle 4 can no longer tie montant 3 this moment, realizes through rotating the crank that first rope 16 tightens up, and this tightening process pulls out hollow tube 1 with montant 3 through polished rod 8, rotates bull stick 27 for the lower extreme of a plurality of montants 3 inclines to the outside, loosens L shape pole 25 this moment and under the effect of second pressure spring 20 and extension spring 18, baffle 4 and depression bar 19 reset.
At the moment, a worker firstly cleans the frame structure formed by the hollow pipe 1 and the vertical pipe 2 by using cleaning cloth, after the cleaning is finished, the driving motor of the first gear 26 is turned on, the two first gears 26 rotate in opposite directions and drive the two brush rollers 12 to rotate in opposite directions, meanwhile, the spray head 13 is opened to spray water, at the moment, a worker holds the drill rod with one hand to enable the lower end of the vertical rod 3 to keep an outward inclined state, the other hand rotates the crank in a reciprocating manner, so that the first rope 16 is repeatedly wound and loosened on the roller 15, the compression and reset rebound driving polished rod 8 which drives the first pressure spring 17 is matched to drive the vertical rod 3 to reciprocate up and down, in the process, the vertical rod 3 reciprocates between the two rotating brush rollers 12, and the spray head 13 sprays water to quickly clean dust on the surface of the vertical rod 3, due to the inclination of the lower end of the vertical rod 3, the water sprayed by the spray head 13 will run along the vertical rod 3 and flow away from the lower end thereof.
After the vertical rod 3 is cleaned, the roller 15 is rotated and the first rope 16 is tightened, the lower end of the vertical rod 3 is higher than the position of the upper hollow tube 1, the rotating rod 27 is rotated to enable the rotating rod 27 to rotate to be vertical, the vertical rod 3 is rotated to be vertical, the roller 15 is loosened to enable the rope to move downwards under the reset action of the first pressure spring 17, the L-shaped rod 25 is pressed to enable the L-shaped rod 25 to extrude the pressure rod 19, the baffle 4 is rightwards passed again, the position of the notch 5 of the baffle is opposite to the through hole of the hollow tube 1 for installing the vertical rod 3, the roller 15 is continuously loosened to enable the vertical rod 3 to reset into the two hollow tubes 1, the L-shaped rod 25 is loosened to enable the baffle 4 to be clamped in the clamping grooves 6 of the plurality of vertical rods 3 again under the reset action of the second pressure spring 20 and the tension spring 18 to achieve the fixation of the vertical rods 3, the main switch 29 is closed, polished rod 8 breaks away from with montant 3, accomplishes above action after, drive electric telescopic handle 23 with chevron shape support 22 rebound for two sleeves break away from two standpipe 2, and remove this device forward, realize this device cunning and shift to behind the next group guardrail directly over, wash next group guardrail.
Compared with the traditional equipment, the device has the following advantages:
1. this device is when wasing the guardrail, extracts a plurality of montants 3 from the frame of guardrail, and the clean dead angle that originally disappears after montant 3 extracts, and the manual work is through quick carrying out standpipe 2 and 1 outer fringe face of hollow tube can realize the washing to the guardrail frame as far as to a plurality of montants 3 that will extract carry out reciprocal cleaning through pivoted brush roller 12 and shower nozzle 13, and the cleaning speed is fast and the cleaning performance is clean not to leave the washing dead angle.
2. Rotating shaft 7 after extracting montant 3 for the west section of montant 3 shifts to the outside, spout the water of montant 3 through shower nozzle 13 this moment again and brush the back through brush roller 12, sewage can be along montant 3 from its lower tip drippage, hollow tube 1 and standpipe 2 are kept away from to the lower tip of montant 3 this moment, consequently, sewage after the washing can not secondary pollution wash good standpipe 2 and hollow tube 1, has stopped remaining the problem of water stain, makes and washs more thoroughly.
3. This device removes through baffle 4 and realizes 3 chucking of montant, removes and installs the back at belt cleaning device, can relax demolish montant 3 alone, and demolish back standpipe 2 and belt cleaning device and adopt the rigid connection mode, resets after accomplishing the washing more accurately can not cause the condition that montant 3 can't insert to original position for this device has more the hommization when using.
The guardrail cleaning device is novel in concept, ingenious in structure and high in practicability, and effectively solves the problems that four corners of the existing guardrail are inconvenient to clean in the cleaning process and water stains are easy to remain after the four corners of the existing guardrail are cleaned.
