Abstract

A self-lifting gantry type bidirectional hoist comprises a crane fixed on a lifting tower; the crane comprises a gantry leg fixed on the lifting tower through a locking hoop; the upper end of the gantry leg is fixedly provided with a machine frame; a lifting and vertical movement system is mounted on the end surface of the lower side of the machine frame; fixed end fixing devices are further fixedto the two ends of the lower side of the machine frame; the lifting and vertical movement system comprises a fixed pulley mounted on an electric trolley; the electric pulley is mounted on the lower end surface of the machine frame; the lower end of the electric trolley is connected with a movable pulley; the lower end of the movable pulley is connected with a lifter; the lower end of the gantry leg is provided with a reverse hook; one end of the reverse hook is connected with the gantry leg, and the other end of the reverse hook is connected to a cross bar on the lifting tower through an electric guide chain; and the lifting tower is further provided with a plurality of limiting blocks. The hoist has the characteristics of novel structure, light weight and simple operation, and also has bidirectional lifting and self-climbing functions.

Description

Technical field [0001] The invention relates to a self-elevating gantry type two-way hoist. Background technique [0002] The lattice column tower or bracket is a commonly used structure in the bridge erection operation. The existing lattice column tower or bracket is usually installed with a tower crane. During construction, the hoisting height is limited by the height of the tower crane, and the structure of the tower crane is complicated, installation and transportation are inconvenient, and the rental cost is also high. Summary of the invention [0003] The purpose of the present invention is to provide a self-elevating mast type two-way hoist, which solves the problems that the hoisting height is limited by the height of the tower crane during the current construction, and the structure of the tower crane is complicated, installation and transportation are inconvenient, and the rental cost is also high. [0004] The technical solution adopted to achieve the above objective is ...
