Procedure and apparatus for inserting articles such as railway sole plates into concrete slabs uses machine with top and bottom plates and six power cylinders

摘要

#CMT# #/CMT# The apparatus, mounted on a transport vehicle, has an insertion arm for the sole plates (4) with a positioning mechanism comprising an upper plate (56) fixed to the vehicle, a lower mobile plate (54) to which the insertion arm is attached, and six or more power cylinders (58 to 63) that allow the mobile plate to be adjusted relative to the fixed plate with six degrees of liberty. The power cylinders are fixed directly to the upper plate and connected to the mobile plate by couplings (66) with three degrees of liberty in rotation, and have non-colinear elongation directions. During operation the power cylinders are positioned to move the insertion arm into a predetermined reference position set by a radiocontrolled laser measuring unit. #CMT#USE : #/CMT# Inserting articles such as railway track sole plates into a supporting surface. #CMT#ADVANTAGE : #/CMT# The apparatus and measuring system provide greater precision for positioning the inserted articles. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the sole plate insertion apparatus. 4 : Sole plates 50 : Sole plate insertion cylinders 54 : Lower plate 56 : Upper plate 58 - 63 : Power cylinders 66 : Couplings.
