Problems solved by technology
In the process of traditional prestressed tensioning construction, simple lifting tools such as steel wire ropes or nylon ropes are used to lift jacks. During the process of jacks being in place, problems of swaying and turning often occur, which makes the installation of jacks in place during the tensioning operation process difficult. At the same time, if the prestressed tonnage is large, the weight of the jack will increase accordingly, and the construction operation of the jack in place at the tensioning place requires two operators to cooperate, which poses a great safety hazard

The invention discloses jack lifting equipment and a lifting method thereof. The jack lifting equipment comprises a walking bracket system (1), a translation system (2) mounted on the outer side of the walking bracket system, and a lifting system (3) connected with the translation system, wherein the walking support system comprises a supporting frame (11), four vertical rods (12) and universal wheels (13), wherein the supporting frame (11) is formed by welding metal components and is in a three-dimensional rectangular shape, the four vertical rods (12) are welded in the four corners of a bearing frame, and the universal wheels (13) are installed at the bottom ends of the vertical rods. The translation system comprises a rectangular rail frame (21) arranged on the outer side of the supporting frame and a translation trolley (22) which is installed in the rectangular rail frame and can reciprocate along the upper rail and the lower rail. The problems that in the bridge superstructure prestress tensioning construction process, an aerial work jack is inconvenient to position accurately and difficult to operate are effectively solved, the structure is stable, operation is easy and convenient, and construction is safe.
Description
technical field [0001] The invention relates to the technical field of highway engineering construction, in particular to a novel jack lifting device and a lifting method suitable for prestressed tensioning construction of bridge superstructures. Background technique [0002] With the continuous increase of bridge span, the use of prestress in bridge structure is more and more extensive. In the process of traditional prestressed tensioning construction, simple lifting tools such as steel wire ropes or nylon ropes are used to lift jacks. During the process of jacks being in place, problems of swaying and turning often occur, which makes the installation of jacks in place during the tensioning operation process difficult. At the same time, if the prestressed tonnage is large, the weight of the jack will increase accordingly, and the construction operation of the jack in place at the tensioning place will require two operators to cooperate, which will pose a greater safety haza...
