Description

Technical Field

[0001] The utility model relates to the technical field of high-speed railway engineering construction devices, in particular to a multifunctional frame for disassembling, assembling and storing a high-speed railway box girder end template. Background Art

[0002] In the prefabrication process of high-speed railway box girders, the installation of the box girder end formwork is a crucial and highly technical link. As a support and shaping tool for the internal structure of the box girder, the box girder end formwork needs to be pulled in and out before and after construction to ensure the dimensional accuracy and overall quality of the box girder.

[0003] Currently, there are two common ways to pull in and out the box girder end formwork in the market. First, a traditional way is to set up a transition frame between the construction platform and the box girder end formwork storage rack. This transition frame acts as a bridge, allowing the box girder end formwork to move smoothly between the two positions. In order to achieve the movement of the box girder end formwork, a gantry crane is usually used as a power source, and the box girder end formwork is pulled by a hand winch. Although this method is simple and direct, it requires manual operation of the gantry crane and hand winch during the operation, and the control accuracy and speed depend on the experience and skills of the operator.

[0004] In recent years, with the advancement of technology and the improvement of automation level, a new type of motor-driven inverted frame has also appeared on the market. This inverted frame uses a motor as a power source and realizes the automatic pulling in and out of the box girder end template through a control system. Compared with the traditional winch method, the motor-driven inverted frame has a higher degree of automation and more stable power output. However, this new inverted frame also has some shortcomings. First, in a construction environment with uneven road surface, the motor-driven inverted frame may tilt due to the instability of the foundation. This tilt not only affects the stability of the inverted frame itself, but more importantly, it will cause the box girder end template pulled in and out by the inverted frame to tilt. Once the template tilts, it is difficult for the installer to adjust it accurately, so that the horizontality of the template cannot be guaranteed, which brings great difficulties to the subsequent installation work. Secondly, the operational flexibility is poor. The motor-driven inverted frame can usually only move the box girder end template according to the preset trajectory and speed, which is difficult to meet the flexible needs in complex construction scenarios.
