Four-shaft united excitation vibration power device

Abstract

The invention discloses a four-shaft united excitation vibration power device. The four-shaft united excitation vibration power device comprises a box body; a first main shaft, a first driven shaft, asecond driven shaft and a second main shaft are sequentially installed in the box body side by side; a first driving gear and a second driving gear are installed on the first main shaft and the second main shaft correspondingly; a first driven gear engaged with the first driving gear and a second driven gear engaged with the second driving gear are installed on the first driven shaft and the second driven shaft correspondingly; the first main shaft and the second main shaft penetrate through the box body and are connected with a driving device; first eccentric blocks are installed on the first main shaft; and second eccentric blocks are installed on the second main shaft. According to the four-shaft united excitation vibration power device, the driving device drives the first eccentric blocks and the second eccentric blocks installed at the two ends of the first main shaft and the second main shaft to rotate to generate vibration; due to the fact that the first main shaft, the secondmain shaft, the first driven shaft and the second driven shaft are installed side by side, the contact area with a vibration table is increased, the needed vibration time is shortened, the amplitude is reduced, and the needed excitation vibration force is convenient to adjust due to the design of the eccentric blocks at the two ends.

Description

Technical field: [0001] The invention relates to the technical field of vibrators, in particular to a four-axis joint excitation force device. Background technique: [0002] At present, the common vibrator on the market is a rod-shaped hollow cylinder with an eccentric vibrator inside. Driven by the motor, it rotates at a high speed to generate high-frequency and small-amplitude vibration. The vibration frequency can reach 12000-15000 times / min. The vibrating effect is good, the structure is simple, and the service life is long. It is suitable for vibrating beams, columns, walls and other components and mass concrete. [0003] When mixing concrete components with a concrete mixer, it is necessary to remove the air bubbles and tamp them to make the concrete compact and eliminate the honeycomb surface of the concrete, so as to improve its strength and ensure the quality of the concrete components. The concrete vibrator is a kind of equipment that uses power to generate frequ...
