Trolley-System für Schalung

Trolley System for Formwork

Hydraulic and mechanical can be used. After analysis and comparison, the hydraulic type frame has low rigidity requirements for the frame, flexible structure and light weight, processing requirements and high elevation requirements for laying tracks during construction are low. Tunnel Trolley is easy to use, but has high self-locking requirements for hydraulic cylinders. The hydraulic cylinders in the lining are not allowed to retract. The mechanical type is the opposite. Since one motor has to drive several screw drives, the requirement for coaxiality of each drive shaft is high, and the frame must have a large rigidity, the structure size is accurate, due to the heavy structure and high processing requirements. Moreover, because the lead screw is synchronous (not like hydraulic transmission, each hydraulic cylinder can be synchronized or can be operated separately). Therefore, when the track elevation error (each point is not at the same level) is large, it will directly affect the position of the template, thus affecting the quality of the lining. After the analysis and comparison, the hydraulic transmission scheme is adopted, and the hydraulic cylinder adopts hydraulic lock and balance valve to make the hydraulic cylinder self-locking. At the same time, the screw mechanism is used for mechanical locking, and the support of the template is strengthened to ensure that the template does not retract and has no deformation when lining. Practice has proved that it is reasonable to adopt hydraulic pressure type for lining trolley and is the development direction.
