Extensible steel form jumbo capable of moving in all directions

Abstract

The invention discloses an extensible steel form jumbo capable of moving in all directions. The extensible steel form jumbo comprises a portal system which is connected with a formwork system througha connecting system, and the lower end of the portal system is connected with a walking system through direction adjusting mechanisms; the portal system comprises a frame part, a plurality of stand columns and a jacking part, the formwork system comprises a top formwork, a left side formwork, a right side formwork, a left bottom formwork and a right bottom formwork, and all the formworks are connected through hinging parts; the connecting system comprises hydraulic jacks and screw jacks, wherein the hydraulic jacks are arranged between the left side formwork and the frame part, between the left side formwork and the left bottom formwork, between the right side formwork and the frame part and between the right side formwork and the right bottom formwork, and the screw jacks are arranged between the left bottom formwork and the frame part and between the right bottom formwork and the frame part. The extensible steel form jumbo can go up and down in a large amplitude, can pass in tunnelswith different sections, can rotate in all directions and can smoothly pass multiple parallel tunnels, and thus the number of jumbos is greatly reduced, disassembling and assembling of the jumbos arereduced, the cost and manpower are saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a telescopic and universally movable steel mold trolley. Background technique [0002] Tunnel lining steel formwork trolleys are more and more widely used in the prior art. Generally, multiple tunnels are constructed in parallel in hydraulic tunnels, and construction branch tunnels are set between the parallel tunnels. When the tunnel length is short, one steel formwork trolley can be used in multiple tunnels. However, because traditional steel formwork trolleys cannot pass through the branch holes, it is often necessary to equip each tunnel with one trolley, or After the trolley is dismantled, it is transferred to another tunnel by means of transportation and then assembled again for construction. The cost of equipment is greatly increased, and the installation and removal of the trolley requires more manpower, which prolongs the overall construction period. [000...

AI Technical Summary

Problems solved by technology

When the tunnel length is short, one steel formwork trolley can be used in multiple tunnels, but because the traditional steel formwork trolley cannot pass through the branch holes, it is often necessary to equip each tunnel with one trolley, or After dismantling the trolley, it will be transported to another tunnel by means of transportation and then assembled again for construction. The cost of equipment will increase greatly, and the installation and removal of the trolley will require more manpower, prolonging the overall construction period.
