The principle of operation of the present invention will now be described as follows: the electric vehicle body 1 is moved to a cement road section to be maintained, a corresponding warning sign is set on a road surface at a proper position, then the electric vehicle body 1 is controlled by personnel to start moving from one side of the road section, and in the moving process, the air pump 10 is started;
when the air pump 10 works, the air pump 10 can convey air into the cavity 9, the air is discharged through each hollow rod 7 and the air groove 6, on a normal road surface, because no gap exists on the road surface, the air can only be discharged from the gap between the bottom of each arc block 114 and the ground, the air can not be discharged, the air pressure in the cavity 9 can be increased, the insulating piston 122 can be pushed to move at the moment, the copper rod 127 can be driven to move and be inserted into the copper ring 129 at the moment, and then the copper rod 127 is contacted with the copper ring 129, the connection loop between the electromagnetic switch 125 and the external power supply is connected, then the power-off delay relay 126 and the buzzer 14 are started, the moving contact of the electromagnetic switch 125 can be attracted due to the magnetic attraction generated by energizing the electromagnetic switch 125, so that the connection loop between the power-off delay relay 126 and the buzzer 14 can be disconnected, the buzzer 14 can not work, in the moving process, if gaps exist on the road surface, the air discharged by each hollow rod 7 can be discharged not only through the gaps between the arc-shaped block 114 and the road surface, but also can be rapidly discharged through the gaps, so that the air pressure in the space-time cavity 9 is rapidly reduced, the insulating piston 122 can be rapidly moved back under the action of the third spring 124, the insulating piston 122 can drive the copper rod 127 to be separated from the copper ring 129, the connection loop of the electromagnetic switch 125 can be disconnected, at the moment, the magnetic attraction of the electromagnetic switch 125 is vanished, under the action of the self elastic element, the movable contact of the electromagnetic switch 125 can rebound, so that a connecting loop of the outage delay relay 126 and the buzzer 14 can be connected, and the buzzer 14 can delay the outage of the buzzer 14 and continuously perform the ringing alarm work even if the trapezoid cover 4 is staggered with a gap due to the movement of the electric vehicle body 1 under the action of the outage delay relay 126, after hearing the ringing of the buzzer 14, an operator can stop the movement of the electric vehicle body 1, then confirm whether a gap exists at the position, continuously start the electric vehicle body 1 to move if the gap does not exist, and change the direction of the electric vehicle body 1 by 90 degrees if the gap exists, namely the vehicle head of the electric vehicle body 1 faces the cross section direction of a cement pavement;
then, the normally closed electromagnetic valve 152 in the inclined spray pipe 151 and the normally open electromagnetic valve 153 in the air tank 6 are electrified, at the moment, the normally closed electromagnetic valve 152 can open the inclined spray pipe 151, the normally open electromagnetic valve 153 can close the air tank 6, at the moment, air conveyed by the air pump 10 during working is sprayed out through the cavity 9, the hollow rod 7 and the inclined spray pipe 151, most of air sprayed obliquely is discharged through a gap under the blocking action of the trapezoid cover 4 and the arc block 114, at the moment, when the air flow passes through the gap, dust and scraps reserved in the gap can be blown out, the electric vehicle body 1 can be controlled to move towards the general direction of the gap, the gap can be subjected to ash cleaning treatment firstly, and after the electric vehicle body 1 moves from one end of the gap to the other end, the vehicle body is turned around 180 degrees again;
then, the electric push rod 17 is controlled to move downwards, the guide steel rod 20 is inserted into the gap by rotating the insulating rotating plate 21, after the lower end of the grouting hard pipe 26 descends to about 1 cm above the ground, the electric push rod 17 is stopped, at this time, the electric vehicle body 1 is controlled to slowly move, during moving, the guide steel rod 20 moves along the gap, at the turning position of the gap, the guide steel rod 20 drives the insulating rotating plate 21 to rotate along with the gap, so that the electric conductive deflection rod 234 can rotate through the insulating elastic pad 233, the conductive deflection rod 234 can be contacted with one arc-shaped conductive plate 232, at this time, the electric deflection rod 234 and the contacted arc-shaped conductive plate 232 can be connected with corresponding indicator lamps 25 to be lightened, at this time, an operator controls the vehicle head of the electric vehicle body 1 to rotate towards the side direction, and controls the deflection angle according to the position of the lightened indicator lamps 25, namely, when the indicator lamps 25 close to the central axis of the electric vehicle body 1 are lightened, the corresponding deflection angle is smaller, otherwise, the corresponding deflection angle is larger, until the indicator lamps 25 are turned off, and after the indicator lamps 25 are turned off, the electric vehicle body 1 is stopped from one end;
in the initial stage of the second movement of the electric vehicle body 1, the grouting pump 281 is synchronously started, the grouting pump 281 can pump out the slurry in the repairing slurry storage tank 27 and inject the slurry into the gap through the grouting hose 282 and the grouting hard pipe 26, so that the repairing along the gap can be completed, and the repairing effect is good;
simultaneously, when the grouting pump 281 starts to work, the motor pump 292 is synchronously started, at this time, the motor pump 292 can pump out the marking liquid in the marking liquid storage tank 291, and the marking liquid is sprayed at the gap position through the connecting pipe 293 and the spray head 295, so that the gap position can be conveniently and rapidly positioned by subsequent personnel, the subsequent inspection and repair effect can be conveniently realized, and the important inspection and maintenance can be carried out on the road section at the position.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
