Normal system, hydraulic cylinder and hydraulic control subsystem including applying load, provides the carrying wall of supporting point, provides component installation
The component installation frame of point, and the auxiliary frame of auxiliary positioning is carried out to component, wherein auxiliary frame is generally arranged at component
The side of installation frame limits non-vibration, the displacement on draw direction for assisting.Below by detailed introduction so that this hair
Bright architecture, use process and principle is described in detail.
It is well known that the general volume of bridge concrete component and self weight are larger, and usually between several tons to tens of tons, one
Kind of bridge beam member, focuses on tens of tons certainly, the system usually be arranged with the workshop that there is row to hang, in laboratory, hung using capable
Bridge member is promoted, still, row is hung as a kind of lifting means not within protection scope of the present invention.Namely
It says, in the specific implementation process of this system, it usually needs it is equipped with row and lifts up into row, but in the case where operating space allows, no
It excludes to carry out upward mobility using height hoisting tools such as crane, manual, electric cucurbits, as long as lifting member can be played
Purpose.Meanwhile after lifting in place, need to carry out secondary accurate adjusting, cannot achieve secondary precisely adjust it at present
Position.It finally needs to lock hydraulic cylinder both ends, to adapt to the needs for stretching, vibrating repeatedly.Certainly, the mesh of member lifts
Be building for system, it is that hoisting process has no effect on experiment as a result, only influence the time schedule in Preparatory work of experiment stage, but
It is that, as a kind of explanation, pedestal of the present invention in the design process, has comprehensively considered above-mentioned situation, and increase in pedestal design
Adjustable factors are added, so that hoisting process is more quickly, precisely.
With reference to Fig. 1, in order to carry out detailed explanation and illustration to this implementation process, this part uses following technology art
Language:
