Energy-storage concrete vibrator adopting variable cross-section channel for accelerating airflow

Abstract

The invention discloses an energy-storage concrete vibrator adopting a variable cross-section channel for accelerating airflow. The energy-storage concrete vibrator structurally comprises a driver anda rod, wherein a signal output end of the driver is electrically connected to the rod through a cable; the rod is of a cylindrical structure and comprises a rod casing, rolling sleeves, an exhaust disc, an air outlet, pistons, a spindle and a seal ring, the two rolling sleeves are vertically symmetrically suspended on the spindle, the seal ring is arranged in an inner chamber formed in the innersides of the rolling sleeves, and the vertically symmetrically distributed pistons are welded at the head end of the spindle and fixed on the inner wall of the rod casing. A prime mover of the conventional vibrator is improved, air source driving is adopted, the energy-storage concrete vibrator is small in inserting resistance besides explosive-proof and waterproof performance, downhole moving operation is facilitated, and through cooperation with an air inlet mechanism, energy consumption is reduced effectively and service life is prolonged greatly while accelerated high-frequency strong vibration is realized.

Description

technical field [0001] The invention relates to an energy-storage concrete vibrator which utilizes a variable cross-section flow channel to accelerate airflow, and belongs to the field of concrete vibrating machinery. Background technique [0002] At present, in the domestic wellbore construction, honeycomb pockmarks, local damage and water seepage on the well wall caused by poor concrete vibrating quality occur from time to time. There is a direct relationship between the vibration force and its ease of operation. In the use of existing vibrators, the prime mover is often used, which not only causes a large loss of energy consumption but also has a short service life, resulting in the vibrator being used for a long time. The vibrating frequency will gradually decrease under use, resulting in a significant decrease in the vibrating quality of the vibrator, which will indirectly affect the vibrating quality of the concrete. Contents of the invention [0003] In view of thi...
