Embodiment Construction

[0016] refer to figure 2 , Fig. 3, an oil cylinder (5) is installed on the vibrating shaft (4), and two pistons (6) and (7) up and down in the oil cylinder (5) pass through oil pipes (8), (9) and hydraulic locks (11) respectively ) connection, through the hydraulic lock to control the movement position of the oil cylinder (5), the inner piston (6), (7) so as to control the oil volume in the upper and lower oil chambers to realize the amplitude modulation of the device. In the present embodiment, two holes are drilled on the vibrating shaft (4), directly used as oil pipes, and directly connected with the hydraulic lock (11). A rotary joint (10) is also installed on the vibrating shaft, and the hydraulic lock device is on one end face of the rotary joint (10). Refer to figure 1 1. The amplitude modulation device (2) is installed in the oil chamber A of the vibrating wheel body, which is filled with lubricating oil. With reference to Fig. 4 and Fig. 5, in order to reduce the oi...

Abstract

The invention discloses a stepless amplitude modulation device of the mechanical vibration wheel of the vibrating compactor. The amplitude modulation device has an axis of vibration and there is an oil cylinder on the axis of vibration. The upper and lower oil pockets beyond the upper and lower pistons in the oil cylinder are connected together through the fuel tube and the hydraulic lock. The hydraulic lock controls the oil mass in the upper and the lower oil pockets to realize the stepless amplitude modulation. There are two triangular plates used to reduce the resistance of the lubricating oil on the outside of the cylinder body of the oil cylinder. The hydraulic lock is fixed on the swivel joint of the vibrating shaft. Because the locations of the upper and the lower pistons can be adjusted at will, we can realize the stepless amplitude modulation from zero swing to high swing and do not produce the impact force.

Description

Technical field [0001] The invention belongs to the technical field of road construction machinery. Background technique [0002] Compaction machinery is a construction machinery mainly used to increase the compactness of the working medium (earth filling and road pavement mixture), and is one of the main construction equipment for road and engineering structure foundations, embankments and road pavement projects. . Vibratory compaction is to make the soil particles in a state of high-frequency vibration by the vibration load issued by the machine, the internal friction force between the particles is lost, and the compressive stress and shear stress generated by the gravity of the machine itself force these particles to line up and be compacted. The traditional vibratory compaction is to compact the ground layer through the combined action of the vibrating wheel's action force and static force. The structure of the vibrating wheel consists of three main parts: the wheel bo...
