Description

Tunnel ditch cleaning device

Technical field:

The invention relates to a road cleaning device, in particular to a tunnel road ditch cleaning device which can be used for cleaning roadside drainage ditches, and belongs to the field of municipal engineering.

Background technique:

Due to the special conditions of the tunnel, the drainage ditch of the internal road is set on both sides of the road surface and is in the form of an open ditch. For example, the drainage ditch of the slow lane in the Shanghai Dalian Road Tunnel is an open ditch with a depth of 85mm and a width of 150mm, and its cross-section is arc-shaped. structure. There is a certain height difference between the bottom of this open ditch type drainage ditch and the road surface, and ordinary sweepers cannot clean up the garbage in the ditch. Ordinary sweeping vehicles are equipped with a cleaning device on the left front, right front and left rear and right rear parts on both sides of the car body. There is a garbage suction port in the middle of the bottom of the car body. Gathered, then sucked into the suction port in the middle and sent into the body waste bin. Since the sweeping disc of the ordinary cleaning device cannot freely change its position and posture in a wide range of space, it can only be adapted to the cleaning of flat ground, but cannot complete the cleaning of the roadside drainage ditch in the tunnel.

In order to keep the above-mentioned Dalian Road Tunnel clean and tidy, the tunnel has been cleaned manually for many years and the road surface is cleaned mechanically. For each cleaning, two cleaners, a sweeper and an engineering vehicle must be arranged for protection. , It took more than 2 hours, so this method is not only labor-intensive and time-consuming, but also brings safety hazards to the cleaning personnel, and also affects the smooth traffic of the tunnel during the cleaning period.

Invention content:

The technical problem to be solved by the present invention is to overcome the deficiency that existing road cleaning devices can only clean flat road surfaces, and provide a tunnel road ditch cleaning device whose sweeping plate can freely sweep away the rubbish in the roadside drainage ditch by changing its position and posture , so that the sweeper can take care of the cleaning of the road surface and side ditches at the same time, thereby improving the cleaning efficiency, ensuring the safety of personnel and keeping the traffic smooth.

The technical scheme that the present invention solves the problems of the technologies described above is as follows:

Detailed ways:

The present invention will now be described in further detail in conjunction with the accompanying drawings and embodiments.

Please refer to Fig. 1 for the structural representation of the present invention, which shows that the tunnel road ditch cleaning device can be installed on a moving car body, and the car body is provided with a dust collection container, which includes a dust suction pipe 1, a rotating sweeping disc 2, a spray nozzle Water device 3, lighting lamp 4 and movable support 5. Referring again to the structural diagram of the dust suction pipe in Fig. 2, the dust suction pipe 1 is arranged on the car body, and it includes a dust suction nozzle 12 and a flexible pipe 11; The lumen of the tube is used to pass through the sucked up garbage and dust, and the upper end of the flexible tube 11 is connected to the dust collection container in the vehicle body. The flexible tube 11 can be stretched, thereby driving the dust suction nozzle 12 to approach or leave the rotary sweeping disc 2; The dust nozzle 12 is connected to the lower end of the flexible pipe 11 and is close to the ground for sucking the garbage on the ground; the flexible pipe 11 of the dust suction pipe 1 is also provided with a valve 6, which can cut off the pipeline of the flexible pipe 11. Referring to Fig. 1 again, the movable support 5 is cantilever-shaped and fixed on the car body, and each member of itself can be stretched and rotated, thereby changing the position of its outer end in space; the movable support 5 includes a rotating part 51. Cantilever part 52, elastic part 54 and hydraulic rod 53; the base of the rotating part 51 is fixed on the vehicle body, and its moving end can rotate left and right around its own axis; the cantilever part 52 is hinged on the rotating part 51 On the moving end of the hydraulic rod 53, it can swing up and down; the elastic member 54 can be a spring, one end of which is connected to the vehicle body, and the other end is connected to the cantilever member 52; And the suspension arm 52, which is driven by the hydraulic system in the vehicle body to promote the swing of the suspension arm 52. The rotary sweeper 2 is disc-shaped, and can rotate around its own axis to clean up the rubbish. Driven by the movable support 5, its relative position and posture relationship with the ground can be changed. Specifically, under the joint action of the hydraulic rod 53 and the elastic member 54 of the movable support 5, the cantilever member 52 can freely change its outer end. In the position of the space, this drives the rotating sweeping disc 2 on the outer end to change its relative position and posture with the ground or the drainage ditch, such as the angle between the rotating sweeping disc 2 and the ground, so as to adapt to cleaning The need for ground or open drains. The back of the dust suction nozzle 12 is provided with an anti-scratch device 7, please refer to the structural diagram of the anti-scratch device in Fig. Along the outer edge of the dust suction nozzle 12, it is used to prevent the dust suction nozzle 12 from being rubbed; It is between two steel plates 73 and can rotate around the axis. The two steel plates 73 are welded to the back of the dust suction nozzle 12. The outer edge of the round wheel of the anti-scratch member 71 protrudes from the outer edge of the dust suction nozzle 12 by about 20 mm. When the cleaning operation encounters an outer obstacle, such as a tunnel anti-collision wall, the anti-scratch member 71 first encounters the obstacle, which avoids the damage of the dust suction nozzle 12 due to direct friction while reminding the driver . Referring to Fig. 1 again, the water spout of described sprinkler device 3 can aim at the road ditch outside the vehicle body or other positions that need to be sprayed with water, so as to avoid dust in cleaning, and this spout is movable to adapt to different Spray direction needs. Described lighting lamp 4 is arranged on the vehicle body, can illuminate ground, gutter and whole tunnel road ditch cleaning device, and it is installed in the end similar to serpentine metal pipe so that adapt to the lighting needs of each position after bending. Referring to Fig. 4, the tunnel road ditch cleaning device of the present invention can be arranged on any movable vehicle, such as an ordinary sweeper, a special sweeper or even a trolley, etc., generally installed at the rear lower part of the car body as shown in the figure.

When starting to use the tunnel road ditch cleaning device, first park the cleaning vehicle at the tunnel crossing, close the original road surface suction pipe valve, open the valve 6 on the dust suction pipe 1, then put down the dust suction nozzle 12, and open the rotary sweeping disc 2 and the water spray device 3, the movable support 5 is driven by the hydraulic control system to adjust the position and angle posture of the rotary sweeping disc 2, and then adjust the dust suction nozzle 12, the water spray device 3 nozzle, the lighting lamp 4, etc. according to the actual situation. Then turn on the start switch and start the vehicle to drive into the tunnel. After entering the tunnel, it needs to drive close to the side ditch and clean at a speed of 15 km/h-20 km/h. When cleaning, it is necessary to control the tunnel road ditch cleaning device and gutter distance.

It has been proved by operation practice that the tunnel road ditch cleaning device of the present invention can suck the granular garbage with a plane density of less than 2g/ ^cm2 in the drainage open ditch, various garbage bags, cigarette butts, and canned boxes with a size of less than 150×80mm, etc. into the vehicle-mounted garbage. After cleaning, basically no garbage can be seen in the drainage ditch. At the same time, the silt and yellow sand deposited in the ditch are also effectively removed. The cleaning effect is significantly improved, and the cleaning cost is also greatly reduced. The annual maintenance cost can be saved by 40,000 to 50,000 yuan.

The greatest advantage of the present invention is that it can not only clean flat road surfaces, but also clean roadside drainage ditches. Therefore, the tunnel road ditch cleaning device is suitable for cleaning roads with roadside ditches, especially for cleaning roads in tunnels.
