Technical field
The present invention relates to the component on road roller, specifically road roller drum assembly.
Background technology
Road roller belongs to the category of road furniture in engineering machinery, be widely used in the embankment compacting operation of the Larger Engineering Projects such as high-grade highway, railway, airfield runway, dam, stadium, sand, half viscosity and clayed soil, subgrade stability soil and asphalt concrete pavement layer can be rolled.
Road roller rolls soil, road surface critical piece is cylinder, cylinder retains certain gap to ensure good rotation when assembling between panel and cylinder, but in cylinder rotation process, the imbalance on road surface can make cylinder produce axial force, cause it to move axially or tilt, cause cylinder on axis body on slide, the simultaneously inclination of cylinder also may damage panel by pressure.
Summary of the invention
The technical problem to be solved in the present invention is to provide the drum assembly preventing from sliding axially or tilting.
For solving the problem, the invention provides a kind of road roller drum assembly, comprise cylinder and axially run through the axis body of described cylinder, described cylinder can rotate around described axis body, the two ends of described axis body are separately fixed on two pieces of panels being fixedly connected with described road roller body, it is characterized in that, a balance clamp device is connected with respectively between the two ends of panel described in two and described cylinder, described balance clamp device comprises its axis and described cylinder end face and to take up an official post the parallel roller of Radius, the periphery of described roller and the end face of described cylinder tangent.
As a further improvement on the present invention, described balancing fixture device also comprises for regulating each described roller to the distance adjusting mechanism of described cylinder end face distance.
As a further improvement on the present invention, described distance adjusting mechanism comprises fastening devices and perpendicular adjusting rod, described roller is rotatably connected in described fastening devices, and described adjusting rod is provided with external screw thread at least partly, and it is connected with an adjusting nut through described panel.
As a further improvement on the present invention, described fastening devices comprises inner ring and outer shroud, described inner ring is connected by some connecting rods with between outer shroud, described roller is rotatably connected on described connecting rod, described inner ring is passed described axis body and can be slided on described axis body, and described adjusting rod is vertically fixed on described outer shroud.
As a further improvement on the present invention, each described fastening devices is equipped with two described adjusting rods, and described adjusting rod is symmetrical about the center of circle of described outer shroud.
Beneficial effect of the present invention is, the both ends of the surface of cylinder are provided with the roller tangent with it, by roller by rotary drum clamping, has because be linearly connected between cylinder and roller, therefore, can't hamper the rolling of cylinder.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As depicted in figs. 1 and 2, the present invention includes cylinder 2 and axially run through the axis body 14 of cylinder 2, cylinder 2 can rotate around axis body 14, the two ends of axis body 14 are separately fixed on two pieces of panels 12 being fixedly connected with road roller body, a balance clamp device is connected with respectively between the two ends of two panels 12 and cylinder 2, balance clamp device comprises its axis and cylinder 2 end face and to take up an official post the parallel roller 6 of Radius, the periphery of roller 6 and the end face of cylinder 2 tangent.
The both ends of the surface of cylinder 2 are provided with the roller 6 tangent with it, are clamped by cylinder 2 by roller 6, because between cylinder 2 and roller 6 be linear contact lay, therefore, roller 6 can't hamper the rolling of cylinder 2.But it should be noted the placement direction of roller 6, it must be parallel with the radius of cylinder 2 end face, otherwise roller 6 two ends will produce a pair couple, causes roller 6 to rotate around its mid point.
As a further improvement on the present invention, balancing fixture device also comprises for regulating each roller 6 to the distance adjusting mechanism 4 of cylinder 2 end face distance.
Be provided with distance adjusting mechanism 4, for regulating the distance between roller 6 and cylinder 2.
As a further improvement on the present invention, distance adjusting mechanism 4 comprises fastening devices 16 and perpendicular adjusting rod 10, roller 6 is rotatably connected in fastening devices 16, and adjusting rod 10 is provided with external screw thread at least partly, and it is connected with an adjusting nut 8 through panel 12.
The adjustment of distance is realized by screw thread pair, when adjusting nut 8 position is fixed, rotates adjusting nut 8, will realize the horizontal movement of adjusting rod 10, thus reach the distance adjustment between cylinder 2 and roller 6.
As a further improvement on the present invention, fastening devices 16 comprises inner ring 20 and outer shroud 22, is connected between inner ring 20 with outer shroud 22 by some connecting rods, and roller 6 is rotatably connected on connecting rod, inner ring 20 is passed axis body 14 and can slide on axis body 14, and adjusting rod 10 is vertically fixed on outer shroud 22.
This structure, can place multiple roller 6 as required, and as long as guarantee that inner ring 20 is concentric with axis body 14, just can ensure that the axis of roller 6 is parallel, easy to operate with the radius of cylinder 2 end face, feasibility is high.
As a further improvement on the present invention, each fastening devices 16 is equipped with two adjusting rods 10, and adjusting rod 10 is symmetrical about the center of circle of outer shroud 22.
Adopt two adjusting rods 10, to be to ensure there are enough bonding strengths with panel 12, two is to facilitate adjustable range.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not limited by the examples; the change done under other any does not deviate from Spirit Essence of the present invention and principle, modification, substitute, combine, simplify the substitute mode that all should be equivalence, be included within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
