Automatic walking and transverse displacement hydraulic template trolley for secondary lining of highway tunnel

Abstract

The utility model provides an automatic walking and transverse displacement hydraulic template trolley for secondary lining of a highway tunnel, relates to the technical field of tunnel trolleys, and solves the problems that the template trolley needs to support a template after being positioned, but the supporting position of a supporting mechanism of a common template trolley is generally designed in a fixed manner, so that the template trolley is inconvenient to operate. Therefore, the problem that tunnel construction is affected due to the fact that a formwork trolley supporting formwork can only be supported after being adjusted for many times is solved, and more time is needed for operation. The utility model discloses an automatic walking and transverse displacement hydraulic formwork trolley for secondary lining of a highway tunnel. The automatic walking and transverse displacement hydraulic formwork trolley is characterized in that a portal frame of a trapezoidal structure is slidably arranged at the top of a trolley bottom plate; through the arrangement of the portal frame and the adjusting joint, the supporting position of the trolley can be changed, so that the supporting position of the trolley is changed, the supporting position can be properly adjusted when the supporting position is improper, the overall adjustment operation of the trolley is omitted, and only the supporting position needs to be adjusted.
