Efficient press wheel assembly for road roller

Abstract

The invention provides an efficient press wheel assembly for a road roller and belongs to the field of engineering machinery. Problems that the construction effect of the existing road roller is poorand the existing road roller cannot adapt to multiple road surfaces are solved. The efficient press wheel assembly for the road roller comprises a frame and a press wheel; an axle hole is formed in the press wheel; a wheel axle is fixed on the frame; the wheel axle penetrates into the axle hole; a plurality of rod grooves are formed in the outer wall of the wheel axle; a plurality of rod holes areformed in the press wheel; the efficient press wheel assembly for the road roller further comprises air outlet rods penetrating into the rod holes; main sliding grooves and sub sliding grooves are formed in the walls of the rod grooves; the main sliding grooves and the sub sliding grooves are arc structures; the diameters of the sub sliding grooves are larger than those of the main sliding grooves; the main sliding grooves and the sub sliding grooves are connected with each other through arc transition; sliding blocks, which are positioned in the main sliding grooves in a sliding manner, arefixed at the rear ends of the air outlet rods; the front ends of the air outlet rods are aligned with the outer wall of the press wheel and can rotate the press wheel around the wheel axle so that thesliding blocks slide to the sub sliding grooves from the main sliding grooves; and the front ends of the air outlet rods extend out of the outer walls of the press wheel and are embedded into the ground in front of the advancing direction of the press wheel. The efficient press wheel assembly for the road roller has the advantages that the construction quality can be improved and the efficient press wheel assembly for the road roller is suitable for various road surfaces.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and relates to a high-efficiency road roller pressing wheel assembly. Background technique [0002] As construction machinery, road rollers can roll sandy, semi-cohesive and cohesive soils, subgrade stabilized soils, and asphalt concrete road surfaces, and are widely used in filling and compacting operations for large-scale engineering projects such as roads, railways, airport runways, dams, and stadiums. . [0003] Existing road rollers can only use rollers to compact the surface of the land. Due to the limited extrusion force, the air inside the land cannot be fully squeezed out, and the compaction effect is poor. The existing application number is "201610319604.1", and the invention name is "a high-efficiency exhaust road bridge roller roller assembly". Cooperate with the magnetic block on the air outlet rod to repel each other to form air outlet holes on the soil to discharge t...

AI Technical Summary

Problems solved by technology

[0004] 1. The skateboard is always located vertically below the action of gravity, so the contact surface between the pressure roller and the road surface is the lowest surface of the pressure roller in the vertical direction, so the pressure roller assembly is only suitable for horizontal road surfaces. If it encounters a slope structure road surface, due to The contact surface between the slope road surface and the pressure roller is not the vertically lower surface of the pressure roller, so the air outlet rod at the position of the pressure roller in contact with the slope road surface will protrude from the outer wall of the pressure roller, which cannot compact the ground, but will affect the flatness of the ground instead. Under certain circumstances, the air outlet rod protruding from the outer wall of the pressure roller may not necessarily penetrate into the soil, so the intended effect cannot be achieved.

[0005] 2. Magnetic block 2 cooperates with magnetic block 1 to repel each other, so that the air outlet rod extends out of the outer wall of the pressure wheel. Therefore, the structure of the extended air outlet rod is unstable, and it is easy to retract under force during the process of entering the soil, which cannot achieve a good performance. Effect

[0007] 4. The air outlet rod is damaged and cannot be disassembled and replaced, and the maintenance cost is high
