As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the present invention discloses a ground cleaning device under a road guardrail. The cleaning device is installed in front of the vehicle, and is composed of a fixed frame 1, a swing frame 2, a limit frame 3 , Connecting rod 4, lifting cylinder 5, lifting guide 6, lifting slide 7, lifting steel chain 8, swing cylinder 9, spring guide 10, spring slide 11, moving pulley 12, fixed pulley 13, wire rope 14, spring 15, cylinder 16. Cylinder head 17, roller 18, positioning wheel adjusting mechanism 19, positioning wheel 20, working mechanism bracket 21, swing lever 22, tension spring 23, stroke switch 24, disc brush 25, probe rod 26, and oil motor 27.

The fixed frame 1 is fixedly installed at the front of the vehicle in a horizontal direction, and the swing frame 2 is composed of a connecting rod frame and a supporting rod frame, wherein one end of the connecting rod frame of the swing frame 2 is hinged on the fixed frame 1 and advances along the vehicle In the direction, the support rod frame of the swing frame 2 is located on the right side of the connection rod frame and is vertically fixed to the other end of the connection rod frame. The cylinder end and the piston rod end of the swing cylinder 9 are hinged to the fixed frame 1 and the swing, respectively. On the connecting rod frame of the frame 2, during operation, under the action of the swing cylinder 9, the swing frame 2 can swing 90 degrees to the left side of the vehicle, so that the connecting rod frame of the swing frame 2 and the fixed frame 1 are parallel to each other. The limit frame 3 is fixed on the fixed frame 1 on the left side of the swing frame 2. When the swing frame 2 swings 90 degrees to the left by the swing cylinder 9, the connecting rod frame of the swing frame 2 and the limit frame 3 Interference occurs, so that the swinging limit of the swinging frame 2 is limited by the limit frame 3.

There are three connecting rods 4, the three connecting rods 4 are equal in length and are arranged in parallel with each other. One end of the connecting rod 4 is vertically hinged on the connecting rod frame of the swinging frame 2. The other end of the connecting rod 4 is vertically hinged on the work. Mechanism support 21, the working mechanism support 21 is arranged in parallel with the swing frame 2. The connecting rod frame of the swing frame 2 and the working mechanism support 21 swing relatively up and down in parallel. When the link 4 is in a horizontal position, the work mechanism support 21 rises to the extreme position relative to the swing frame 2, and as the connecting rod 4 swings downward, the working mechanism bracket 21 gradually descends to the working position.

The lifting rail 6 is welded on the right side of the supporting rod frame of the swinging frame 2 along the direction of the supporting rod frame of the swinging frame 2. The lifting rail 6 is a rectangular steel pipe, There are two symmetrical long holes processed in the length direction of the steel pipe. The lifting slide frame 7 is slidably installed in a long hole of the lifting rail 6. The lifting oil cylinder 5 is arranged on a support rod frame of the swing frame 2 on the left side of the lifting rail 6, and the cylinder end and the piston rod end of the lifting oil cylinder 5 are hinged to the support rod frame and the lower sliding frame 7 of the swing frame 2, respectively. One end of the lifting steel chain 8 is hinged on the lowering slide frame 7, and the other end of the lifting steel chain 8 is hinged on the working mechanism support 21. When the piston rod of the lifting cylinder 5 contracts inward, the lifting slide frame 7 moves along the long hole of the lifting guide rail 6 toward the lifting cylinder 5 along with the piston rod of the lifting cylinder 5 and tightens the lifting steel chain 8, The working mechanism support 21 is gradually moved upward by the lifting steel chain 8. When the piston rod of the lifting cylinder 5 is retracted to the extreme position, the working mechanism support 21 will be driven to the highest point, and the cleaning device is in a non-working state at this time. When the piston rod of the lifting cylinder moves outward, the lifting slide frame 7 moves along the long hole of the lifting guide rail 6 away from the lifting cylinder 5 along with the piston rod of the lifting cylinder 5 and releases the lifting steel chain 8. The steel chain 8 drives the working mechanism bracket 21 to gradually move downwards until the working mechanism bracket 21 is lowered to the working position to start the working mode. Here, the working mechanism bracket 21 will drive the swing cleaning rod 22 and the end cleaning actuators such as the disk brush 25 to move together. .

The spring guide rail 10 is welded and fixed to the working mechanism support 21 in the direction of the connecting rod 4. The structure of the spring guide rail 10 is similar to that of the lifting guide rail 6. The spring guide rail 10 is also a rectangular steel pipe and extends along the length of the rectangular steel pipe. Machined with symmetrical long holes. The spring slide frame 11 is slidably installed in the long hole of the spring guide rail 10 and slides left and right along the long hole of the spring guide rail 10. The movable pulley 12 is installed on the spring slide frame 11. The fixed pulley 13 is fixed on the working mechanism bracket 21 on the right side of the spring guide rail 10. The cylinder 16 is a two-way piston rod cylinder. The cylinder body of the cylinder 16 is fixed on the working mechanism bracket 21. The end of the piston rod on one side of the cylinder 16 is hinged with the spring sliding frame 11. The end of the piston rod on the other side of the cylinder 16 The part is hinged with the cylinder head 17. A roller 18 is mounted on an end of the cylinder head 17. One end of the wire rope 14 is connected to the working mechanism bracket 21, and the other end bypasses the fixed pulley 13 and the movable pulley 12 and is connected to one end of the spring 15, and the other end of the spring 15 is connected to the rear end of the swing lever 22. A roller 18 provided at an end of the cylinder head 17 abuts the inner side of the swing lever 22.

When the piston rod of the cylinder 16 protrudes in the direction of the swing lever 22, since the cylinder 16 is a two-way piston rod cylinder, the spring slide frame 11 also drives the movable pulley 12 on the spring slide frame 11 to the swing lever under the action of the cylinder 16 piston rod. Sliding in the 22 direction. According to the principle of the relationship between the moving pulley and the fixed pulley, the stroke of the end of the wire rope 14 is twice the stroke of the moving pulley 12. Therefore, when the piston rod of the cylinder 16 is extended toward the swing rod 22, the spring carriage 11 is also driven The movable pulley 12 slides to the limit position in the direction of the swing lever 22, and at this time, the pulling force of the spring 15 is the smallest, which is convenient for overcoming obstacles, as shown in FIG. 6. When the piston rod of the cylinder 16 protrudes away from the swing lever 22, the spring carriage 11 will drive the pulley 12 to the limit position away from the swing lever 22. At this time, the tensile force of the spring 15 is the largest, which is convenient for normal routine operations such as Figure 5 shows.

The swing rod 22 is an arc-shaped rod bent and arranged in a direction toward the swing frame 2, and a middle portion of the swing rod 22 is hinged to the working mechanism bracket 21 through a rotating shaft. The oil motor 27 is vertically installed at the end of the head end of the swing lever 22, and the lower part of the motor 27 is drivingly connected to the disc brush 25.

Driven by the connection of the swing bar 22, the disc brush 25 extends below the road rail and is driven by the oil motor 27. Since the road rail has a column every few meters, a 300 mm square is under the column When the disc brush 25 is swept to the base, the disc brush 25 should be withdrawn to the outside of the base, and then returned to the original position for cleaning. Therefore, a probe 26 is provided. When the disc brush 25 approaches the railing base, the probe 26 First, when it hits the base of the railing, the probe rod 26 swings. The end of the probe rod 26 leaves the stroke switch 24. The stroke switch 24 outputs a signal to the outside. Through the PLC control, the piston rod of the cylinder 16 extends in the direction of the swing rod 22. The roller 18 on the head 17 abuts on the swing lever 22, and as the piston rod of the cylinder 16 projects outward, the cylinder head 17 connected to the end thereof drives the roller 18 to roll along the swing lever 22 and pushes the swing lever 22 to swing The disk brush 25 at the end of the swing lever 22 quickly leaves the base, but at this time, the bristles of the edge of the disk brush 25 are still in contact with the base. After the disk brush 25 passes the base, the piston rod of the cylinder 16 will quickly retract, and the swing lever 22 is in the spring. 15 make the brush quick Return to the initial normal working position, and at the same time, the probe 26 is also returned to the initial position under the action of the tension spring 23.
