Description
本发明属于城市清洁环保设备技术领域，具体涉及马路隔离栏地面清扫装置。The invention belongs to the technical field of urban clean and environmental protection equipment, and particularly relates to a road cleaning device for a road isolation fence.
起初在城市环卫工作中，马路隔离栏清冼多采用人工擦洗方式，劳动强度大且存在安全隐患，给环卫工人增添了很多负担。近几年来，马路隔离栏清洗机很好的解决了这一问题，但马路隔离栏清洗机工作时留下的泥水也同时流到隔离栏的下方马路上，在隔离栏的正下方路面上总是残留有泥水，无法一次性收集清理干净，致使此区域需要二次清扫，因此，这一区域成为无法采用现有的马路隔离栏清洗机清扫的“死角”。通常这一区域的二次清扫是通过人工或高压水清洗，其中，人工清扫不仅工作强度大，而且也增加了清扫者的人身安全风险；而高压水清洗将该区域时，灰尘都被冲到马路中间位置附近，使得另一车道的吸扫车无法实时进行收集，致使该区域部分的水分蒸发后，各种灰尘依旧随车而起，造成二次污染环境，无法达到高效清洁的目的。At the beginning of the urban sanitation work, the road separation fence was mostly cleaned by manual scrubbing, which was labor intensive and had potential safety hazards, which added a lot of burden to the sanitation workers. In recent years, the road barrier cleaning machine has solved this problem very well, but the mud water left by the road barrier cleaning machine also flows to the road below the barrier, on the road directly below the barrier. There is muddy water remaining, which cannot be collected and cleaned at one time, so that this area needs to be cleaned twice. Therefore, this area becomes a “dead corner” that cannot be cleaned by the existing road isolation column cleaning machine. Usually, the secondary cleaning in this area is cleaned by manual or high-pressure water. Among them, manual cleaning not only increases the work intensity, but also increases the personal safety risk of the sweeper. When the high-pressure water washes the area, the dust is washed away. Near the middle of the road, the suction truck of the other lane cannot be collected in real time, so that after the water in the area is evaporated, various dusts still follow the car, causing secondary pollution and failing to achieve efficient cleaning.

如图4所示，三组所述盘刷1呈放射状沿圆周均匀分布，且相互之间无干涉，当马路隔离栏地面清扫装置开始作业时，其将被调整至合适的工作位置，即盘刷的刷毛伸过马路隔离栏，覆盖马路隔离栏正下方的路面，且不影响盘刷和连接支架总成的正常运转，马达4启动后，马达4驱动主动直齿轮5顺时针旋转，连接支架中心大直齿轮6逆时针旋转，连接支架中心大圆锥齿轮8也将逆时针旋转，此时，盘刷连接支架总成3在连接支架中心大圆锥齿轮8的带动下逆时针旋转，进而带动三组盘刷1逆时针联动旋转；连接支架中心大圆锥齿轮8进一步驱动水平轴12首端的水平传动圆锥齿轮9旋转，并通过水平轴12的传递，带动水平轴12末端的水平传动圆锥齿轮9旋转，进而带动盘刷驱动圆锥齿轮11顺时针旋转， 此时，在盘刷驱动圆锥齿轮11的驱动下，每一组盘刷1将顺时针自转。如图4所示方向，清扫车向前行进，每一组盘刷1顺时针自转，盘刷连接支架总成3逆时针旋转，二者反向旋转的设计，保证了该清扫装置在清扫行进作业过程中，盘刷连接支架总成3和盘刷1顺利越障，当盘刷连接支架总成与马路隔离栏立柱底端在瞬间将要接触时，通过清扫车向前行进和盘刷连接支架总成的旋向将有效地越过隔离栏的支撑立柱，保证清扫作业顺利进行。As shown in FIG. 4, the three sets of the disc brushes 1 are evenly distributed along the circumference in a radial direction without mutual interference. When the road cleaning device of the road barrier starts to work, it will be adjusted to a suitable working position, that is, a disc. The brushed bristles extend across the road barrier to cover the road surface directly below the road isolation fence, and do not affect the normal operation of the disk brush and the connection bracket assembly. After the motor 4 is started, the motor 4 drives the driving spur gear 5 to rotate clockwise, and the bracket is connected. The center large spur gear 6 rotates counterclockwise, and the large bevel gear 8 of the connecting bracket center also rotates counterclockwise. At this time, the disc brush connecting bracket assembly 3 rotates counterclockwise under the driving of the large bevel gear 8 at the center of the connecting bracket, thereby driving three The set disc brush 1 rotates counterclockwise; the connecting bracket center large bevel gear 8 further drives the horizontal drive bevel gear 9 at the head end of the horizontal shaft 12 to rotate, and transmits the horizontal drive bevel gear 9 at the end of the horizontal shaft 12 through the transmission of the horizontal shaft 12. Then, the disk brush driving bevel gear 11 is rotated clockwise. At this time, under the driving of the disk brush driving bevel gear 11, each group of disk brushes 1 will rotate clockwise. In the direction shown in Figure 4, the sweeping car travels forward, each set of disc brush 1 rotates clockwise, and the disc brush connection bracket assembly 3 rotates counterclockwise, and the reverse rotation design ensures that the cleaning device is cleaning. During the operation, the disc brush connection bracket assembly 3 and the disc brush 1 smoothly pass the obstacle. When the disc brush connection bracket assembly and the bottom end of the road isolation column are in contact at an instant, the vehicle is moved forward by the sweeping vehicle and the brush is connected to the bracket. The assembly's direction of rotation will effectively pass over the support column of the barrier to ensure smooth cleaning operations.
