In order to solve the technical problem, the utility model provides a technical scheme does: the box girder external mold lifting appliance comprises L-shaped frames which are symmetrically arranged, wherein the bottom ends of the two L-shaped frames are connected through a positioning plate, the top ends of the two L-shaped frames are connected through a cross beam, the corners of the two L-shaped frames are connected through a reinforcing beam, the reinforcing beam and the upper portion of the cross beam are connected through a hanging beam, one side of the bottom end of each L-shaped frame is connected with an L-shaped bearing frame, a positioning block is connected with the same side of the L-shaped bearing frame on the positioning plate, and a positioning groove is formed in the positioning block.
Furthermore, the cross section of the reinforcing beam is of an L-shaped structure with an arc-shaped inner side corner.
Furthermore, one end of the hanging beam close to the reinforcing beam is provided with a main hanging hole, and the other end of the hanging beam is provided with a plurality of auxiliary hanging holes.
Further, the positioning groove extends to the middle of the positioning plate.
Furthermore, the side surfaces of the positioning plate and the L-shaped frame, which are far away from the positioning groove, are jointly connected with a reinforcing plate.
Compared with the prior art, the utility model the advantage lie in:
the L-shaped bearing frame is arranged to stably limit and place the outer box girder mold, so that in order to avoid shaking in the hoisting process, positioning grooves are arranged corresponding to the vertical steel on the outer side of the outer box girder mold, and the vertical steel is positioned and placed by the positioning grooves, so that the outer box girder mold can be better attached to the bearing box girder mold;
the reinforcing beam is arranged to enhance the stability of the top of the structure, the hanging beam is connected and arranged above the reinforcing beam and is connected through the main hanging hole, and the auxiliary hanging hole is used for adjusting the gravity center, so that the external mold of the box girder can be hoisted better;
the fixed plate is arranged, the L-shaped frame and the positioning plate are further connected in a reinforced mode, and the overall structural stability of the lifting appliance is better.
