Abstract

The invention discloses a continuous variable cross-section tunnel lining formwork trolley. An upright column (7) and an upright supporter (9) are respectively connected to the two ends of a portal moving cylinder (3); a side formwork positioning bracket (5) is connected to the outer side of the upright column (7); a lateral moving wheel (6) is arranged on a lower beam (13); in a cross section of the trolley, the upright columns (7) on two sides are connected through a portal cross beam (2) and a portal middle cross beam (4); in a vertical section of the trolley, the upright columns (7) on two sides are connected through an upper beam (11), a middle beam (12) and a lower beam (13); a crossing brace (14) is arranged between adjacent upright columns (7); a walking system (15) is respectively connected to the upright columns (7) and the lower beam (13); the portal cross beam (2) comprises an inner portal cross beam and an outer portal cross beam; the inner portal cross beam is arranged in the outer portal cross beam; the portal middle cross beam (4) comprises an inner portal middle cross beam and an outer portal middle cross beam; and the inner portal middle cross beam is arranged in the outer portal middle cross beam.

Description

technical field [0001] The invention relates to a tunnel lining formwork trolley. Background technique [0002] Tunnel lining formwork trolley is a kind of mechanical equipment used for secondary lining in tunnel construction, and is widely used in railway, highway and water conservancy and hydropower engineering construction. Using this equipment can improve the quality of concrete lining, speed up the construction progress and improve efficiency. In the tunnel construction design, due to the different types of geological surrounding rocks and the difference in the turning radius of the tunnel, the section size of each tunnel is different, and even the section size of each section of the same tunnel often changes. If a formwork trolley is manufactured for each section, it will obviously increase the construction cost, so the formwork trolley must be designed as a variable section trolley to meet the construction needs of different sections.
