Description
Technical Field
The utility model relates to the field of bridge construction, in particular to a lifting beam portal frame.
Background
In actual engineering, the steel box girder is put on the bridge, the forward movement is transported, and the construction process of transferring to the transport beam dolly is transferred, and traditional technical scheme uses gantry crane and crane. However, due to the limitation of construction sites and the consideration of safety factors, the requirements on construction precision and the like and the disadvantages of the traditional technical scheme are very obvious. In response to these problems, the development of "GGB-200 type lifting beam door frame" is of great significance.
The use of traditional gantry crane in the work progress is very convenient, but its requirement to the place is stricter, and its installation and the process of transporting the case roof beam need consume quite a long time, also consumes a large amount of manpower and materials. The gantry crane requires a professional installer for installation and operation since it is a special equipment itself, and also requires acceptance by a quality inspection department, which is a considerably long period from a plan to a construction implementation. Aiming at the current tense construction period of each item, the gantry crane is not cost-effective to use.
Therefore, the development of the lifting beam portal frame becomes a problem to be solved urgently in the whole society.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that the gantry crane in the prior art needs professional installation personnel to install and operate due to the fact that the gantry crane is special equipment, and needs to pass the acceptance of a quality inspection department, so that the period from a scheme to construction implementation is quite long, and the like.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a lifting beam portal frame comprises steel pipe columns, transverse connection systems are arranged among the steel pipe columns, a left steel pipe column device and a right steel pipe column device are formed by the steel pipe building main and the transverse connection systems, a left fixing device is arranged on the side face of the left steel pipe column device, a right fixing device is arranged on the right steel pipe column device, a concrete main beam is arranged on the right fixing device, a plurality of supporting columns are arranged on the concrete main beam, cross beams are arranged on the supporting columns, and a beam transporting trolley is arranged on the cross beams.
Furthermore, the top of the steel tube upright post is provided with a longitudinal and transverse distribution beam.
Furthermore, the left side fixing device comprises a first bearing platform and an attached wall, and the steel pipe upright is fixed on the first bearing platform.
Further, the right fixing device comprises a second bearing platform.
Furthermore, one end of the concrete main beam is fixed in the second bearing platform.
Furthermore, a fixed connecting piece is arranged on the supporting upright post.
Compared with the prior art, the method has the advantages that: by adopting the structure, the construction safety risk can be effectively reduced, the construction efficiency is improved, and the economic feasibility is realized. Due to the fact that the installation conditions and the structure are simple, corresponding adjustment can be conducted according to site construction conditions, the application range is wider, construction risks are reduced, and construction efficiency is improved. The structure setting of support post, concrete girder and steel pipe stand supports more firmly.
