Automatic multi-point expansion type efficient concrete vibrating rod

Abstract

The invention discloses an automatic multi-point expansion type efficient concrete vibrating rod, and belongs to the field of concrete vibrating rods. According to the automatic multi-point expansiontype efficient concrete vibrating rod, when the automatic multi-point expansion type efficient concrete vibrating rod is inserted into concrete, a dynamic sealing piece can be pushed to move upwards by utilizing the concrete, so that the gas pressure in a space formed by the dynamic sealing piece, a sleeve and a vibrating guide rod is gradually increased, gas enters an open strip-shaped bag to enable the open strip-shaped bag to expand, and then a limiting rod is pushed to move through the open strip-shaped bag; when the automatic multi-point expansion type efficient concrete vibrating rod enters the deep part of the concrete, the limiting rod is far away from a magnetic wrapping expansion rod, the limiting effect on the magnetic wrapping expansion rod is lost, the magnetic wrapping expansion rod is automatically opened outwards to different degrees under the action of magnetic force, and large-range vibration of the interior of the concrete is realized; and in addition, the closing process of the magnetic wrapping expansion rod can be automatically realized when the automatic multi-point expansion type efficient concrete vibrating rod is pulled out, redundant manual operation is not needed in the whole process, large-range vibration of the concrete is realized without affecting the normal use of the automatic multi-point expansion type efficient concrete vibrating rod, and thevibration efficiency of the concrete is effectively improved.

Description

technical field [0001] The invention relates to the field of concrete vibrating rods, in particular to an automatic multi-point expansion type high-efficiency concrete vibrating rod. Background technique [0002] When the concrete is poured with a concrete mixer, the air bubbles must be removed and tamped 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 above-mentioned process of eliminating air bubbles and tamping concrete is concrete vibration. According to the method of transmitting vibration: there are three types: internal vibrator, external vibrator and surface vibrator; according to the power source of the vibrator: there are three types: electric type, internal combustion type and pneumatic type, and electric type is used The most widely; classification according to the principle of vibrator vibration: there are two kinds of eccentric type and planet...

Problems solved by technology

[0003] In the prior art, in order to enable the vibrating rod to quickly pass through the buried steel support during the pouring process, the vibrating rod is generally in the shape of a vertical long rod, which greatly reduces the vibrating area and increases the vibrating frequency. Seriously reduces the efficiency of concrete vibrating
