Abstract
The invention discloses a pressing wheel of roller, comprising pressing wheel, transmission shaft, chain wheel and spoke supporting said pressing wheel. Joint spokes are set on inner walls of two ends of said pressing wheel. The other end of said spoke is fixed with the outer side wall of bearing sleeve. Bearings are embedded into said bearing sleeve and there are covers at two ends of bearing sleeve. Two ends of said transmission shaft are embedded into the bearing. One end of said transmission shaft is fixed with the chain wheel. There is rotating hammer in said pressing wheel and said rotating hammer is fixed with the transmission shaft. The invention adjusts the pressure to ground by pressing wheel by adjusting the rotating speed of transmission shaft. It not only lessens the weight of roller greatly but also saves fuel. It has higher use value and popularization value.
Description
Technical field
The present invention relates to a kind of building machinery, specifically, relate 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 object of the present invention is 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 solution adopted in the present invention is: a kind of 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 solution of the present invention:
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 present invention 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 present invention is simple in structure, easy to use, can regulate pinch roller pressure, has higher use value and promotional value.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention front view;
Accompanying drawing 2 is an embodiment of the invention 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.
