The vehicle body 1 is provided with a hydraulic device, a front wheel 4 and a rear wheel 5; the hydraulic device connects the first and second rotation cylinders 17 and 18.
The invention relates to a crawler-type road roller, which comprises a road roller body and a road roller triangular crawler wheel. The triangular crawler wheel is connected with the road roller body through the connecting frame. When the road roller is mainly used for road surface construction, roughness is increased between a cement concrete layer and an asphalt layer, so that the effect of improving the strength of the road surface is achieved.
The road roller body comprises a cab assembly, a walking part and a hydraulic system. The walking part consists of a front wheel and a rear wheel, wherein the rear wheel provides driving force and steering for the road roller. Meanwhile, the front wheels can realize the lifting and descending functions through the control of a hydraulic system. When the road roller works, the front wheel is lifted, the self weight of the vehicle body is distributed on the triangular crawler belt and the rear wheel, and the compaction effect is enhanced.
The triangular crawler wheel of the road roller comprises a support, a vibration mechanism, a wheel core and a wheel surface body wrapped outside the wheel core, wherein the outer surface of the wheel surface body is provided with a plurality of grooves, and the grooves are transversely arranged on the crawler wheel surface body at equal intervals. Wherein the bracket is connected with the vehicle body and the triangular crawler wheels.
The wheel core is composed of a driving wheel, a tension wheel 1 and a tension wheel 2, wherein the driving wheel is provided with driving force by an oil motor and drives the triangular crawler wheel to rotate.
A row of vibration mechanisms are arranged in the grooves in the outer surface of the wheel surface body, and each vibration mechanism is composed of a plurality of cam structures and a plurality of compaction blocks. The cam driving shaft is coaxially driven along with the crawler driving wheel, and when the road roller works, a vibration force is formed in the groove to enhance the groove compaction effect.
The steering mechanism comprises a rotary oil cylinder 1, a rotary oil cylinder 2, a connecting shaft, a rotary support 1 and a rotary support 2. Wherein the rotary support is connected with the front end of the vehicle body, and the rotary support 2 is connected with the triangular crawler connecting frame. When the road roller is steered, the front wheel of the road roller descends and is grounded, the triangular crawler wheel longitudinally ascends through the rotary oil cylinder 1, and meanwhile, the rotary oil cylinder 2 is adjusted to achieve horizontal steering of the triangular crawler wheel.
The track is a rubber track, and the support surface of the rubber track is flexible and has buffering performance, so that local deformation can be generated, rolling cracks cannot be generated on the road surface, exposed small stones are not easy to roll and break, and the service performance of the mixture can be ensured. When the rubber crawler wheel body is pressed on a cement road surface, the cement road surface can be partially squeezed into the groove under the pressure of the wheel surface body, the road surface squeezed into the groove squeezes the rubber crawler to enable the convex part of the crawler to deform, and when the wheel surface body leaves the cement road surface, the convex part restores the shape and pushes cement residues squeezed into the groove out of the groove.
When the road roller is used for flattening a cement road surface, the road roller advances on the road surface, the front wheel of the vehicle body of the road roller is lifted, the triangular crawler belt forms a certain angle with the ground, and the acting force is concentrated on one line to operate on the cement road surface. When the lug boss on the triangular crawler belt is pressed on a road surface, the driving wheel rotates, the cam shaft inside and the driving wheel rotate together to drive the compaction block to move up and down according to a certain rule, and the groove pressed out by the lug boss is compacted again. The flexible force of rubber track can let the cement road surface squeeze into in the recess, compresses the rubber track simultaneously, rotates when the road roller, and recess on the rubber track leaves on the cement road surface on, just leaves one protruding line on the cement road surface, and the recess is released to debris in the recess to the resilience of rubber track, keeps clean in the recess, prevents to lead to protruding line unevenness on the cement road surface because of blockking up the object in the recess. When the road roller steers, the triangular crawler belt is rotated and lifted by the rotary oil cylinder 1, and then the rotary oil cylinder 2 is adjusted to steer the triangular crawler belt; when the road roller stops working, the front wheel of the vehicle body is put down, the rotary oil cylinder 1 is adjusted to enable the triangular crawler belt to be lifted upwards, the vehicle can normally run at the moment, and the problem that the road roller needs to be carried by other vehicles when working in a long distance is solved.
