Special watering and rolling vehicle for road construction
The invention discloses a special watering and rolling vehicle for road construction, the special watering and rolling vehicle structurally comprises wheels, a cab, a waterproof baffle and a rolling structure, the wheels are mounted at the bottom of the cab, the waterproof baffle is welded to one side of the cab, and the rolling structure is arranged at the bottom of the waterproof baffle. The gravity impact force of the iron ball is greater than the limited extrusion force between the iron ball and the jacking bag, the in-place iron balls cause downward traction to the telescopic pockets, thesituation that the gravity center of the grinding roller in the middle deviates, consequently, the grinding roller has the'heaviness and lightness' lost rotation phenomenon, and smooth road construction is affected is avoided, the contact area with the road surface can be increased through the structure of the beveling plate, and friction force between the cutting edge and the road surface and friction force between the guide sliding way and the road surface are increased in an auxiliary mode. The road holding device can be effectively contacted with dry and fluffy sandy soil so as to increase road holding force, and the problem that the construction quality cannot be effectively controlled when the dry and fluffy sandy soil on a road surface is rolled is avoided.
本发明公开了一种道路施工专用洒水碾压车,其结构包括车轮、驾驶室、防水挡板、碾压结构，车轮安装在驾驶室底部，驾驶室一侧焊接连接有防水挡板，防水挡板底部设有碾压结构，本发明通过铁球的重力冲击力大于与顶位囊之间限制挤压力，到位后的铁球对伸缩兜造成向下坠的牵引，避免其中部碾压辊轮的重心发生偏离，导致碾压辊轮有“头重脚轻”的丢转现象，影响道路施工的顺利进行，采用斜切板的结构可以增加与路面的接触面积，辅助增加刃口和导向滑道与路面的摩擦力，可以有效和沙土较干并且蓬松相接触以加大抓地力，避免在路面的沙土较干并且蓬松进行碾压时，无法达到施工质量有效控制的基本目标。
