Abstract
The utility model discloses a pressing wheel for road rollers, which comprises a pressing wheel, a transmission shaft, a chain wheel and a spoke supporting the pressing wheel; wherein a connective spoke is arranged on the inner wall at each end of the pressing wheel; the other end of the spoke is connected with the outer side wall of a bearing sleeve; a bearing is embedded inside the bearing sleeve; caps are arranged at both ends of the bearing sleeve; the two ends of the transmission shaft are embedded into the bearing; the chain wheel is connected with one end of the transmission shaft; a rotary hammer is arranged inside the pressing wheel; the rotary hammer is connected with the transmission shaft. The utility model adjusts has the advantages of adjusting the pressure of the pressing wheel upon the ground by adjusting speed of the transmission shaft, reducing weight of a road roller largely and saves fuel as well as high use value and promoting value.
Description
Technical field
The utility model relates to a kind of building machinery, specifically, relates to a kind of pressure roller of road roller.
Background technology
Along with rapid economic development, China continues to increase the input to infrastructure construction, and building roads and bridges is very important building project, in the construction of engineering, need use a lot of engineering mechanical devices, wherein road roller one of the equipment that is absolutely necessary.The present road roller that uses, the wheel body inside of pinch roller is solid, and wheel body is steel wheel, and weight is very big, and no matter whether road roller is in running order, is constant all the time to the pressure on ground.So on the building site of construction, road roller is implemented compacting operation, but on other ground, the damage of starting road pavement of road roller is very big, adding wheel body is rigidity, often with the ground pressure break.Because the road roller own wt is big, also be not easy to use other vehicle transport, and traditional road roller starts, the power that needs are very big both wasted energy, and also increased construction cost.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, can regulate pinch roller pressure and energy-conservation pressure roller of road roller.
For achieving the above object, the technical scheme that the utility model adopted is: pressure roller of road roller, the spoke that comprises pinch roller, power transmission shaft, sprocket wheel and support pinch roller, all be fixed with the connection spoke on the inside wall at described pinch roller two ends, the other end of described spoke and the lateral wall of bearing holder (housing, cover) are fixedly connected, described bearing holder (housing, cover) is embedded with bearing, the two ends of bearing holder (housing, cover) have end cap, the two ends of described power transmission shaft embed in the bearing, one end and the sprocket wheel of described power transmission shaft are fixedly connected, the inside of described pinch roller has the hammer of commentaries on classics, and described commentaries on classics hammer is fixedly connected on the power transmission shaft.
Below be the improvement of technical solutions of the utility model:
Being welding between the inside wall at described spoke pinch roller two ends, being welding between the other end of described spoke and the lateral wall of bearing holder (housing, cover), for welding, is key connecting between described power transmission shaft and the sprocket wheel between described commentaries on classics hammer and the power transmission shaft.
Described commentaries on classics hammer has through hole for the weight of center of gravity away from power transmission shaft in the position near power transmission shaft.
Described pinch roller inside has some groups changes hammer, has angle between every group of commentaries on classics hammer.
Beneficial effect: the utility model adopts said structure, has the following advantages:
(1) regulate the pressure of pinch roller to ground by the rotating speed of regulating power transmission shaft, a road roller can be according to the pavement grade requirement, and each soil layer of road pavement carries out compacting.
(2) because pinch roller inside be hollow, greatly alleviate the weight of road roller, stop operating, just can make as common vehicle, can road pavement not cause damage at road traveling as long as commentaries on classics is hammered into shape.
(3) because not only light and flexible is started in the weight saving of road roller, and fuel saving, use cost greatly reduced.
The utility model is simple in structure, easy to use, can regulate pinch roller pressure, has higher use value and promotional value.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the utility model embodiment front view;
Accompanying drawing 2 is the utility model embodiment lateral view.
The specific embodiment
Embodiment, as shown in Figure 1, pressure roller of road roller, comprise pinch roller 1, power transmission shaft 2, the spoke 4 of sprocket wheel 3 and support pinch roller 1, all be welded with spoke 4 on the inside wall at described pinch roller 1 two ends, the lateral wall welding of the other end of described spoke 4 and bearing holder (housing, cover) 5, described bearing holder (housing, cover) 5 is embedded with bearing 7, the two ends of bearing holder (housing, cover) 5 have end cap 6, the two ends of described power transmission shaft 2 embed in the bearing 7, and an end of described power transmission shaft 2 and sprocket wheel 3 are by key connecting, and sprocket wheel 3 is driven by chain by the diesel engine on the road roller, the inside of described pinch roller 1 has the hammer of commentaries on classics 8, and described commentaries on classics hammer 8 is fixedly connected on the power transmission shaft 2.
As shown in Figure 2, on the power transmission shaft 2 of pinch roller 1 inside, install two groups and change hammer 8, angle is 45 ° between two groups of commentaries on classics hammer 8 center lines, change hammer 8 and have through hole 9 in position near power transmission shaft 2, so just make the center of gravity of changeing hammer 8 away from power transmission shaft 2, when changeing hammer 8 rotations, can produce bigger centrifugal force with less quality.
