(1) Compare traditional template mode of transporting to needs to accomplish with the help of lifting device, only need carry the case roof beam template through the dolly main part along the traction force with the help of the hoist in slipform track consignment, convenient operation is swift, effectively stops the template and takes place to collide with the problem that has the potential safety hazard in hoist and mount in-process.
(2) The slip form construction of a simply supported box girder is realized through the trolley main body, the bottom of the template support frame is provided with the bottom support screw rods along the bilateral symmetry of the trolley main body, the left gravity center and the right gravity center are placed on the trolley main body, the gravity center deviation can not occur, the template is inclined, the steel wire rope traction trolley main body of the winch moves forward at a constant speed, the stability in the transportation process is ensured, and the application prospect is very large.
To sum up, have convenient operation swift, transportation stability is strong, advantage such as security height.
Drawings
Fig. 1 is a schematic view of the application state of the present invention in lowering the mold.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
referring to fig. 1, a formwork transfer trolley for construction of a simply supported box Liang Huamo comprises a pair of left and right slip form rails 1 spaced in a right direction and a trolley body 2 sliding along the slip form rails 1.
The slip form track 1 adopts 10# channel steel, and the slip form track 1 is respectively and longitudinally laid on the Bailey beam bracket system under the simply supported box beam flange plates on two sides.
The trolley main body 2 consists of a supporting platform 21 for bearing the box girder template component 3 and pulleys positioned at four corners of the bottom of the supporting platform 21.
The supporting platform 21 is preferably made of square steel of 50 mm-70 mm x 50 mm-70 mm and is lapped into a square frame structure.
