Description

TECHNICAL FIELD

[0001] The utility model relates to bridge construction engineering equipment technical field, concretely relates to a open-close mould mechanism. BACKGROUND

[0002] The bridge machine is also called as the bridge building machine, and is a kind of mechanical equipment specially used for bridge construction. It can complete multiple links in the overall construction of bridge, such as bridge pouring and the like. The use of the bridge machine can greatly improve the efficiency and quality of bridge construction, and reduce the input of manpower and material resources.

[0003] The main truss of the bridge machine suspends a formwork in front, and the formwork includes an inner formwork and an outer formwork. The pouring space of the box girder is formed after the inner formwork and the outer formwork are combined. After a section of the box girder is poured through the formwork, the formwork needs to be opened. The main truss carries the formwork and walks forward. After walking to the position, the formwork is combined to pour the next section of the box girder. The pouring of the entire box girder is completed through the above-mentioned reciprocating operation.

[0004] The slide beam is a beam body for bearing the outer formwork. When pouring concrete, the front end of the slide beam is anchored to the front cross beam through the fine rolled threaded steel, and the rear end of the slide beam is anchored to the built box girder through the fine rolled threaded steel. When the formwork needs to be opened and adjusted to walk forward, the fine rolled threaded steel connected with the slide beam is disconnected. The front end of the slide beam is connected to the front cross beam through the steel cable of the manual hoist, and the rear end of the slide beam is connected to the door curtain through the steel cable of the manual hoist. When the formwork is opened, the slide beam is lowered by the manual hoist, so that the top of the outer formwork is separated from the bottom of the flange of the box girder. When walking to the position and needing to combine the formwork, the slide beam is lifted by the manual hoist, so that the top of the outer formwork is flush with the bottom of the flange of the built box girder, and then the slide beam is anchored by the fine rolled threaded steel.

[0005] The existing technology adjusts the height of the slide beam through the steel cable of the manual hoist, and then completes the opening and closing of the outer formwork. The disadvantage is that the outer formwork cannot move horizontally when the formwork is opened. The vertical plate of the outer formwork still rubs and contacts the outer side of the box girder, which has large resistance when the formwork walks forward and easily scratches the outer side of the box girder. At the same time, since the steel cable is a soft material, the outer formwork is easy to shake during the forward movement of the formwork, which has safety hazards. UTILITY MODEL CONTENTS
