Technical field
The present invention relates to the component on road roller, is road roller drum assembly specifically.
Background technology
Road roller belongs to the category of road furniture in engineering machinery, the embankment compacting operation that is widely used in the Larger Engineering Projects such as high-grade highway, railway, airfield runway, dam, stadium, can roll sand, half viscosity and clayed soil, subgrade stability soil and asphalt concrete pavement layer.
Road roller rolls soil, road surface critical piece is cylinder, cylinder when assembling panel and cylinder between retain certain gap to ensure good rotation, 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 to slide on axis body, the inclination of cylinder simultaneously also may be damaged panel by pressure.
Summary of the invention
The technical problem to be solved in the present invention is to provide and prevents the drum assembly that slides axially or tilt.
For addressing the above problem, the invention provides a kind of new 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 panels that are fixedly connected with described road roller body, it is characterized in that, described in two, between panel and the two ends of described cylinder, be connected with respectively a balance clamp device, described balance clamp device comprises its axis and the described cylinder end face parallel roller of Radius of taking up an official post, and the periphery of described roller and the end face of described cylinder are tangent.
As a further improvement on the present invention, described balancing fixture device also comprises for regulating the distance adjusting mechanism of each described roller to 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, is provided with at least partly external screw thread on described adjusting rod, and it is connected with an adjusting nut through described panel.
As a further improvement on the present invention, described fastening devices comprises interior ring and outer shroud, between described interior ring and outer shroud, be connected by some connecting rods, described roller is rotatably connected on described connecting rod, described interior ring is through described axis body and can on described axis body, slide, 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 about the center of circle symmetry of described outer shroud.
Beneficial effect of the present invention is, is provided with the roller tangent with it in the both ends of the surface of cylinder,, has because be connected for linear between cylinder and roller rotary drum clamping by roller, therefore, can't hamper the rolling of cylinder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of fastening devices in Fig. 1;
Wherein: 2-cylinder; 4-distance adjusting mechanism; 6-roller; 8-adjusting nut; 10-adjusting rod; 12-panel; 14-axis body; 16-fastening devices; 18-connecting rod; Ring in 20-; 22-outer shroud.
The specific embodiment
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 panels 12 that are fixedly connected with road roller body, between the two ends of two panels 12 and cylinder 2, be connected with respectively a balance clamp device, balance clamp device comprises its axis and the cylinder 2 end faces parallel roller 6 of Radius of taking up an official post, and the end face of the periphery of roller 6 and cylinder 2 is tangent.
In the both ends of the surface of cylinder 2, be provided with the roller tangent with it 6, by roller 6, cylinder 2 clamped because between cylinder 2 and roller 6 for line contacts, 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 faces, otherwise roller 6 two ends will produce a pair of couple, cause roller 6 to rotate around its mid point.
As a further improvement on the present invention, balancing fixture device also comprises for regulating the distance adjusting mechanism 4 of each roller 6 to cylinder 2 end face distances.
Be provided with distance adjusting mechanism 4, for the distance between roller 6 and cylinder 2 is regulated.
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, is provided with at least partly external screw thread on adjusting rod 10, and it is connected with an adjusting nut 8 through panel 12.
The adjusting of distance realizes by screw thread pair, in the time that adjusting nut 8 positions are fixing, rotates adjusting nut 8, will realize the horizontal movement of adjusting rod 10, thereby reaches the distance adjustment between cylinder 2 and roller 6.
As a further improvement on the present invention, fastening devices 16 comprises interior ring 20 and outer shroud 22, between interior ring 20 and outer shroud 22, is connected by some connecting rods, and roller 6 is rotatably connected on connecting rod, interior ring 20 passes axis body 14 and can on axis body 14, slide, and adjusting rod 10 is vertically fixed on outer shroud 22.
This structure, can place multiple rollers 6 as required, and, as long as guarantee that interior ring 20 is concentric with axis body 14, just can guarantee that the axis of roller 6 is parallel, easy to operate with the radius of cylinder 2 end faces, 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 about the center of circle symmetry of outer shroud 22.
Adopt two adjusting rods 10, one, can guarantee has enough bonding strengths with panel 12, and the 2nd, can facilitate adjustable range.
Above-described embodiment is preferably embodiment of the present invention; but embodiments of the present invention are not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present invention and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
