Up-down floating type concrete acoustic vibrator

Abstract

The invention discloses an up-down floating type concrete acoustic vibrator and belongs to the technical field of concrete vibration. A plurality of vibrating bodies can do up-down reciprocating movement on the outer sides of vibrating rods by matching a magnetic shielding body, a magnetic body, a magnetic block and strong tensile springs, so that the vertical vibrating positions of the pluralityof vibrating bodies in the vibrating process can be changed, and floating type vibration can be realized without an external mechanical driving force; the vibrating bodies consist of main acoustic vibrating balls, main elastic envelops and other structures; vibrating particles fill parts between the main acoustic vibrating balls and the main elastic envelops; vibration sound waves produced by an acoustic generator are imported into the main acoustic vibrating balls through inner acoustic holes and outer acoustic holes and then a plurality of vibrating particles are pushed to resonate, so thatacoustic vibration transmitted from the main elastic envelops to the outside is effectively enhanced; and the vibration sound waves are matched with a plurality of auxiliary vibrating bodies distributed on the outer sides of the main elastic envelops, so that the vibrating effect of concrete is enhanced and the vibrating range is also widened.

Description

technical field [0001] The invention relates to the technical field of concrete vibrating, and more specifically relates to an up and down floating concrete acoustic vibrator. Background technique [0002] In the process of concrete pouring, it is usually necessary to use a concrete vibrator to vibrate the poured concrete to improve the uniformity of each part of the pouring body, eliminate internal air bubbles, and prevent hollowing. [0003] After searching, the Chinese patent authorization number is CN104746880B, which discloses "Electronic Universal Concrete Vibrator", which includes a spherical shell, the surface of which is covered with through holes, and a spherical cavity is formed inside; the spherical shell is wrapped with a A layer of elastic film, which seals each through hole of the spherical shell; a rigid rod is fixedly connected above the spherical shell; the rigid rod has a channel extending along the axis, and the channel communicates with the spherical cav...

Problems solved by technology

However, there are still the following disadvantages: the vibrator can only vibrate at a certain depth when vibrating. If you want to change the vibrating position in the vertical direction, you need to adjust the vertical position of the vibrator up and down. location, the vibrating operation is a bit cumbersome, and it is difficult to perform vibrating operations in the vibrating range more easily by repeatedly floating up and down, and the operating range is also limited
