Alignment adjusting device for tunnel lining formwork trolley and control method

The invention discloses an alignment adjusting device for a tunnel lining formwork trolley and a control method. Mainly, ultrasonic range finders symmetrically installed on the two sides of a formwork adjusting beam are used for measuring the distances between the ultrasonic range finders and a suspension heavy plate suspended at the center point of a tunnel opening, the distances are input in a controller, after analytical judgment is carried out, the controller adjusts the working position of a three-position four-way electromagnetic directional valve, a piston rod of a hydraulic oil cylinder is controlled to stretch or shrink, the transverse position of a tunnel lining formwork is adjusted through the formwork adjusting beam, and alignment adjustment is completed. The adjusting device is simple in structure, convenient to operate and high in adjusting precision, the safety of construction staff is guaranteed, and the construction quality is improved. 本发明公开了种用于隧道衬砌模板台车的对中调节装置及控制方法，主要是通过对称安装于模板调节梁两侧上的超声波测距仪测
