Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0022] The present invention is a kind of single-drum road roller that can change the compaction quality, such as figure 1 As shown, it includes a steel wheel 1, a front frame 2, a rear frame 11 and tires 9; the front frame 2 and the rear frame 11 are articulated through hinge pins 3, and the counterweight adjustment mechanism includes a main arm hydraulic cylinder 4 and an auxiliary arm Hydraulic cylinder 6, one end of the main arm hydraulic cylinder 4 is hinged on the rear frame 11, the other end is welded with a hook 12, one end of the auxiliary hydraulic cylinder 6 is hinged on the rear frame 11, and the other end is hinged on the main arm hydraulic cylinder 4 cylinder body There are 5 hinge points of the main and auxiliary hydraulic cylinders; the counterweight in this preferred example ...

The invention provides a single-steel-wheel road roller with a compaction mass changing function. The mass distribution of the road roller can be subjected to optimal adjustment under different working conditions, and the single-steel-wheel road roller is simple in structure, reasonable in design and convenient to use. The single-steel-wheel road roller comprises a front roller frame, a rear roller frame, a steel wheel, tyres, a balance weight and a balance weight adjusting mechanism, wherein the front roller frame and the rear roller frame are connected in a hinged mode, the steel wheel is arranged on the front roller frame and used for compaction, the tyres are arranged on the rear roller frame and used for driving, the balance weight can be arranged on the front roller frame or the rear roller frame, and the balance weight adjusting mechanism is used for changing the arrangement position of the balance weight. The balance weight arranged on the road roller is adjusted through the mechanical structure, the mass of the road roller is distributed, and thus compaction quality and transfer efficiency are improved; during road compaction, the balance weight is moved forwards through cooperation of a connecting rod mechanism formed by a main arm hydraulic cylinder and an auxiliary arm hydraulic cylinder, and the weight of the steel wheel is increased, so that the compaction effect is greatly improved; and during transfer, the balance weight is moved backwards through cooperation of the connecting rod mechanism formed by the main arm hydraulic cylinder and the auxiliary arm hydraulic cylinder, the weight of the rear roller frame is increased, the attachment force of the rear roller frame is increased, and driving force is increased.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a single steel wheel road roller capable of changing compaction quality. Background technique [0002] Single-drum road rollers have been widely used in road construction. As we all know, the overall quality of the road roller is fixed, and the front and rear distribution quality is also fixed. The greater the distribution quality of the front vehicle, the better the compaction quality, and the larger the distribution quality of the rear vehicle, the stronger the driving ability of the whole vehicle. The proportion of full hydraulic single drum vibrating wheel is more than 60% of the weight of the whole machine, and the proportion of the vibrating wheel of mechanically driven road roller is about 50% of the weight of the whole machine. Studies have shown that the greater the mass of the vibrating wheel, the better and more obvious the compaction effect. Similarly, the greate...
