Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated box girder construction, in particular to a prefabricated box girder transverse movement device. Background Art

[0002] The prefabricated beams are usually placed on the prefabricated bridge piers by means of a bridge erecting machine. The bridge erecting machine belongs to the category of cranes, and its main function is to lift the beams, transport them to the location, and then lower them. The requirements of the bridge erecting machine on the construction site are stringent, and sufficient space is required for installation and operation. The site is greatly restricted, and the equipment operation cost is high. That is, when the prefabricated box beam is moved horizontally, it is not economical to use the bridge erecting machine, and the construction site is narrow, and the use of a truck crane cannot smoothly drop the beam into place. In order to solve these problems, a corresponding transverse movement device is usually designed to replace the bridge erecting machine to move the prefabricated box beam.

[0003] For example, the Chinese patent application publication number CN112591692A discloses a prefabricated box beam transverse movement device, including two sets of parallel transverse movement mechanisms, the prefabricated box beam crosses the two sets of transverse movement mechanisms, each set of transverse movement mechanisms includes a guide rail, a bearing slide that can move along the guide rail, and a driving member for driving the bearing slide to move, and the two ends of the bearing slide are respectively installed with limiting side supports located on both sides of the prefabricated box beam, and the top of the limiting side support is equipped with a top support body for supporting the intersection of the inclined web and flange of the prefabricated box beam. The device can limit the side position of the prefabricated box beam by setting left and right limiting side supports on the bearing slide, so as to avoid the beam body from shifting, shaking or even becoming unstable on the slide during the transverse movement of the beam body. The above device is not limited by the site and has a wide range of applications.

[0004] When the above device is used, the driving cylinder is started, the horizontal push bearing slide is pushed forward, and then the cylinder fixing seat is moved forward, the position of the driving cylinder on the guide rail is adjusted, and the horizontal push bearing slide is pushed forward again, and this step is repeated until the prefabricated box beam is moved horizontally into place. However, such repeated adjustment of the position of the driving cylinder on the guide rail to achieve the horizontal movement of the prefabricated box beam greatly reduces the work efficiency of the horizontal movement of the prefabricated box beam and affects the construction progress.

The motor drive is connected to the moving wheel, and the rotation of the motor drive is converted into the rolling of the moving wheel along the side wall of the guide rail, and then the rolling of the moving wheel drives the bearing slide to move along the guide rail, so as to realize the transverse movement of the prefabricated box beam, and at the same time, it is not necessary to repeatedly adjust the position of the driving cylinder on the guide rail, which greatly improves the transverse movement efficiency of the prefabricated box beam.

On the one hand, the friction force between the moving wheel 4 and the side wall of the guide base rail 1 is increased, which is conducive to ensuring the speed of the moving wheel 4 moving along the side wall of the guide base rail 1 and avoiding slipping. On the other hand, the bearing slide 2 is restricted on the guide base rail 1 to avoid the bearing slide 2 from deviating along the guide base rail 1.
