Slipform paver concrete compaction vibrator

Abstract

The invention relates to a cement concrete compaction external vibrator, especially to a slipform paver external vibrator for compulsive compaction of cement concrete during continuous pouring of kerbs, side ditches and other structures. The concrete compaction vibrator comprises a box body. A longitudinally arranged high speed shaft is disposed at a central position inside the box body. A low speed shaft and a drive shaft are arranged on two sides of the high speed shaft symmetrically. The middle parts of the low speed shaft and the drive shaft are respectively in fixed connection with a first eccentric block. The middle part of the high speed shaft is in fixed connection with a second eccentric block. The low speed shaft, the high speed shaft and the drive shaft are provided with transmission gears. One side of the box body is equipped with a driving hydraulic motor that drives the drive shaft to rotate. With a stable structure, the slipform paver concrete compaction vibrator provided in the invention can remove the concrete adhered to a template lower surface so as to ensure a smooth surface of a concrete structure.

Description

technical field [0001] The invention relates to an external vibrator for cement concrete compaction, in particular to an external vibrator used for forced compaction of cement concrete by a slip form paver in the process of continuously pouring curb stones, side ditches and other structures. Background technique [0002] Most of the existing slip-form pavers use plug-in vibrating rods for dense molding. The required concrete slump must be stable within a reasonable range. If the slump is too high, the paved structure will collapse. Falling deformation; the slump is too low, the workability of the concrete is poor, it is difficult for the vibrating rod to compact it evenly, and the structure is not full, internal potholes and other defects. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a concrete compacting vibrator for a slipform paver that can force compact cement concrete during continuous pouring of st...
