Transfer machine for box girder side form

Abstract

The invention discloses a transfer machine for a box girder side form. The transfer machine for the box girder side form is characterized in that two tracks are arranged on a supporting platform in parallel under the box girder side form and in the transferring direction of the box girder side form; running steel wheels on two sides of a steel frame cart are supported on the tracks in the corresponding positions and can roll along the tracks; rollers are arranged on a cross beam of the steel frame cart in rows, the axes of the rollers are parallel to the tracks, and each roller can roll around a fixed axis; the falling box girder side form can be supported on the rollers by means of a lower joint plate of the box girder side form, is moved outwards on the steel frame cart overall by means of the rollers by a distance and then is transferred on the tracks along with the steel frame cart. The box girder side form directly falls onto the steel frame cart and is transferred on site, so that the box girder side form can be transferred safely and rapidly, and the construction progress is guaranteed.

Description

technical field [0001] The invention relates to a trolley for transporting box girder side forms, more specifically a transport tool for quickly reversing box girder side forms in a narrow space where hoisting and hoisting equipment cannot be used. Background technique [0002] In the existing technology, the dismantling of the side formwork of the box girder is usually performed by a crane first, then transported to the next site by a car, and then installed by a crane again. [0003] However, for the complex environment in a narrow space, the lifting equipment cannot support it, and there is a great safety risk during hoisting and transshipment. At the same time, the transshipment speed is slow and the transshipment cost is high. For example, the Guangzhou Metro Line 21 construction bid 19, the Xiangzhong viaduct section adopts multi-connected continuous rigid structures. The viaduct of this project is located on the Guangshan Highway from Guangzhou to Zengcheng. The const...

[0003] However, for complex environments with narrow spaces, the lifting equipment cannot support it, and there is a great safety risk during hoisting and transshipment. At the same time, the transshipment speed is slow and the transshipment cost is high

For example, the Guangzhou Metro Line 21 construction bid 19, the Xiangzhong viaduct section adopts multi-connected continuous rigid structures. The viaduct of this project is located on the Guangshan Highway from Guangzhou to Zengcheng. The construction space is very narrow, and the distance between the structural side of the beam body and the retaining wall About 1.35m, and the other side of the structure is about 7.35m away from the fence wall. There are two-way four-lane roads outside the fence, and the space inside the fence is narrow. All formwork is steel formwork, which cannot be hoisted by automobile cranes and other machinery, and steel bars are hoisted , Formwork hoisting and dismantling are difficult to complete. The total length of the bridge is 2500m, with a total of 26 continuous rigid structures, the longest of which is 172m, the beam width is 24.9m, and the pier height is about 15m. The way and speed of formwork inversion also affect the construction progress and A key factor in cost
