Exterior feature expands outwardly, so as to fit in the tunnel of different size section.
Top template in existing equipment, which only has, is swung up an action, and after side template is swung out, will be with top
Gap is produced between template, in actual use, linking template is laid by manual site to fill up this gap, but in reality
Because of the heavier-weight of linking template in operation, there is position and install the problem of difficult.
In view of the defects of above-mentioned existing top template is present, the present inventor is rich for many years based on such product engineering application is engaged in
Rich practical experience and professional knowledge, and coordinate the utilization of scientific principle, actively it is subject to research and innovation, adds to found a kind of can adjust
Wide section, it is set to have more practicality.
Utility model content
The utility model provides a kind of adjustable widened section, effectively reduces the difficulty of linking model sheetinstallat and positioning
Degree.
To achieve these goals, the utility model employs following technical scheme：
Adjustable widened section, applied to widening for lining trolley backform, including middle backform, side backform, fixed seat and liquid
Compressing cylinder；
Middle backform is fixedly connected with fixed seat, and cylinder body of hydraulic oil cylinder is fixedly connected with fixed seat, hydraulic cylinder piston rod
It is fixedly connected with side backform, hydraulic jack is used to adjust horizontal range of the side backform relative to middle backform.
Further, adjustable widened section is additionally provided with guider, the fortune for opposite side backform relative to middle backform
It is dynamic to be oriented to.
Further, guider is guide rod, and is positioned in the cavity inside side backform and/or middle backform.
Further, can adjust widened section also includes positioner, is filled for opposite side backform and/or middle backform with being oriented to
The relative position put is fixed.
Further, positioner includes the screwed hole being arranged on side backform and/or middle backform, and and screwed hole
The bolt of adaptation.
Further, at least two pillars, cylinder body of hydraulic oil cylinder is provided between middle backform and fixed seat to fix with pillar
Connection.
Further, pillar is I-steel.
The beneficial effects of the utility model are：
By backform and side backform among setting, and the relative position between the two can be adjusted by hydraulic jack,
It may be such that side backform is relatively easy to realize relative to the movement of middle backform, and the two can simultaneously play and linking template is determined
Position effect, so as to reduce the fixed and positioned difficulty of linking template.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
