Abstract
The utility model relates to a roller of a road rolling machine, which is characterized in that the radial periphery of the roller is uniformly distributed with three identical arching parts. The roller of a road rolling machine can generate the bigger working pressure on the road surface when driven by the external force to roll (the quicker of the running speed of the roller is, the bigger of the generated impact pressure is). The utility model has the advantages of high compaction capacity, and good quality.
Description
The utility model relates to a kind of pressure road cylinder of road roller
The pressure road cylinder of the existing a kind of road roller of China is cylindric, and the gravity of cylinder will pass to the road surface by the arc-shaped surface of cylinder, thereby realizes the purpose on compacting road surface.But the ability on this roller compaction road surface will be subjected to the restriction of its deadweight, thereby be difficult to bring into play bigger effect.
The purpose of this utility model is the pressure road cylinder that a kind of road roller will be provided, and can road pavement produce bigger operating pressure when it rolls under the traction of external force.
The main feature of the utility model structure is that the radial outer periphery of this cylinder is spared three the arching portions that are furnished with.
The utility model rolls forward under external force traction, and when cylinder transfers (as Fig. 4) when being contacted with ground by another arching portion to by an arching portion of periphery, along with the whereabouts of center of gravity, cylinder will be to the bigger surge of ground generation.In addition, when cylinder is contacted with ground by the protruding end of arching portion (as Fig. 3), because contact surface is less, so with respect to the cylindric cylinder with weight same with it, also can be to the bigger pressure of ground generation.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the organigram of embodiment
Fig. 2 is the right view of Fig. 1
Fig. 3 is the schematic diagram of embodiment duty one
Fig. 4 is the schematic diagram of embodiment duty two
With reference to accompanying drawing, the construction features of the pressure road cylinder of road roller of the present utility model are: 1) this cylinder radial outer periphery surface is made up of three identical arched surfaces 1, and the head and the tail two ends line 2 of each ogive curve can form an equilateral triangle on the cylinder end face.2) arch portion encircles partially towards the reverse direction of cylinder.
The pressure road cylinder of the road roller of present embodiment is running forward under the effect of tractive force F, presses tread surface by an arching portion 3 before this, ground is implemented the pressure (as Fig. 3) that strengthens gradually; When cylinder transfers (as Fig. 4) when being contacted with ground by another arching portion to by an arching portion of periphery, because the cylinder center of gravity falls, impel cylinder that ground is produced a bigger surge (speed of cylinder operation is fast more, and the surge of generation is just big more) again, so go round and begin again.
The utility model simple structure, reasonable in design.It can not only produce bigger operating pressure to ground, and compaction quality is good.Therefore has bigger application value.
Claims (3)
1, a kind of pressure road cylinder of road roller is characterized in that this cylinder radial outer periphery is even to be furnished with three arching portions.
