旋挖桩机导杆式抓斗

Dig grab bucket of quick -witted guide arm formula of stake soon

Abstract

The utility model discloses a dig grab bucket of quick -witted guide arm formula of stake soon relates to the dig grab bucket of quick -witted guide arm formula of stake soon that a connecting rod forced synchronization excavated. It solves in the present diaphragm wall construction grab bucket of lifting rope formula to meet and excavate the hard soft intensity contrast in layer and do not can't rectify and pressor problem during great or hard formation. The utility model discloses the telescopic drill rod that digs the stake machine soon passes through clutch movable sleeve and the fixed cover swing joint of the clutch on the frame body top, be equipped with the hydro -cylinder respectively in the upper portion of frame body bisymmetry side, lower tip at the frame body do not is connected with two grab buckets through the pivot symmetry, the fill of two grab buckets top is connected through the connecting axle and the piston rod of frame body both sides hydro -cylinder respectively, tip at this connecting axle do not is connected with the connecting rod, the other end of two connecting rods is connected on synchronizing shaft's tip, synchronizing shaft establishes the central inslot at the frame body. The utility model discloses a grab bucket guidance quality is good, and the grooving perpendicularity is high, grab tu lida through hydraulic loading, be suitable for the construction of pan soil layer and husky ovum layer.
本实用新型的名称是旋挖桩机导杆式抓斗,涉及一种连杆强制同步挖掘的旋挖桩机导杆式抓斗。它主要是解决目前连续墙施工中吊绳式抓斗遇到挖掘层硬软强度差别较大或硬层时无法纠偏和加压的问题。本实用新型旋挖桩机的伸缩钻杆通过离合器活动套与框架体顶端上的离合器固定套活动连接,在框架体的上部两对称侧分别设有油缸,在框架体的下端部分别通过转轴对称与两个抓斗连接,两个抓斗的斗顶分别通过连接轴与框架体两侧油缸的活塞杆连接,在该连接轴的端部分别连接有连杆,两个连杆的另一端连接在同步轴的端部上,同步轴设在框架体的中心槽内。本实用新型的抓斗导向性好,成槽垂直度高;通过液压加压抓土力大,适合于硬土层及沙卵层施工。
