Moving beam trolley and method for horizontally and vertically moving beams using same

Abstract

The invention discloses a moving beam trolley and a method for horizontally and vertically moving beams using the same. The moving beam trolley is characterized in that the moving beam trolley adopts a lifting device to lift a beam support disk on a trolley; and in the reversing process of the moving beam trolley, the beam support disk on the trolley is fixed, and only the trolley body rotates. In the method of the moving beam trolley to horizontally and vertically move beams, four moving beam trolleys are fixed as a whole, the horizontal and vertical reversing processes can be realized by that each trolley body rotates successively and the beam support disk does not rotate in the rotation process. For the transportation and transition process of large-tonnage box beams, the invention can better adapt to various roadbed road conditions, reduces field area requirements on beam transportation fields, and can be used for the field of transition and transportation of large-tonnage box beams.

Description

technical field [0001] The invention relates to the field of transfer and transportation of box girders, in particular to a method for vertically and horizontally moving a beam using a beam-moving trolley. Background technique [0002] In the beam field construction, the transfer and transportation of long-span and large-tonnage box girders are generally combined with beam transport trolleys and gantry cranes. Since beam transport trolleys can only run in one direction, beam field transfer transport can only be stored or equipped in a narrow and long range. Multiple beam transport trolleys are needed to solve the problem, which restricts the site selection of the beam yard, or the investment is too large. The previous box girder transportation also used a tire-type beam transport trolley, which can realize in-situ steering, so that the box girder can be transferred vertically and horizontally. In this way, the beam and the vehicle rotate together. In addition, this The stee...

[0002] In the beam field construction, the transfer and transportation of long-span and large-tonnage box girders are generally combined with beam transport trolleys and gantry cranes. Since beam transport trolleys can only run in one direction, beam field transfer transport can only be stored or equipped in a narrow and long range. Multiple beam transport trolleys are used to solve the problem, which restricts the site selection of the beam yard, or the investment is too large

The previous box girder transportation also used a tire-type beam transport trolley, which can realize in-situ steering, so that the box girder can be transferred vertically and horizontally. In this way, the beam and the vehicle rotate together. In addition, this The steering of this type of trolley also requires good foundation treatment and better beam transport lines, which is not convenient for popularization and application
