For Highway bridge engineering

Tunnel Lining Trolley Steady Flexible

Available in hydraulic and mechanical versions. Compared with the hydraulic type of the frame, the rigidity request is low, the structure type is sensitive, the weight is light, the request for the processing request and the laying trajectory in the construction is low, and the use is convenient, but the hydraulic cylinder has high self-locking request, and the hydraulic cylinder in the lining is not Allow retraction. The mechanical type is the opposite. Because one motor drives several screw drives, the coaxiality of each drive shaft is high, and the frame must have a large rigidity and accurate structure. Due to the heavy structure and high processing requirements, Moreover, since the lead screw is synchronized, when the track elevation error is large, it will directly affect the orientation of the template, and then affect the quality of the lining. After the analysis and comparison, the hydraulic transmission plan is adopted, and the hydraulic cylinder adopts hydraulic lock and balance valve to make the hydraulic cylinder self-locking; the supporting screw structure is used for mechanical determination, and the support of the template is strengthened to ensure that the template does not return when lining Shrink, no deformation. Practice has proved that the lining trolley is hydraulically reasonable and is the development direction.
