Problems solved by technology

However, with the increase of the hoisting span (such as hundreds of meters to thousands of meters) and the increase of hoisting weight (such as hundreds of tons or even hundreds of tons), its economy has dropped significantly, mainly as a wire rope for hoisting the main cable The number will increase greatly, resulting in a significant increase in economic investment

Abstract

The invention discloses a wheel-rail type loading and traveling cable crane. The cable crane comprises traveling systems (6), lifting systems (7), a control system (16) and a main truss structure (15) and is characterized in that the traveling systems (6) are movably mounted on traveling guide rails (1) on two sides, the main truss structure (15) is connected between the traveling systems (6), winches (8) of the lifting systems (7) are arranged in the main truss structure (15), lower parts of the winches (8) are connected with lifting tools (19), and the control system (16) and an engine (17) are mounted in the main truss structure (15); each traveling system (6) comprises a traveling mechanism body (4), a tractor assembly (2) and traveling roller trains (3), the tractor assembly (2) is mounted on one side surface of the traveling mechanism body (4), and the traveling roller trains (3) with gaps reserved are connected with two sides of the bottom of the traveling mechanism body (4). The cable crane is simple in structure, efficient, practical, safe, stable and good in economy.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a wheel-rail type load traveling cable-carried crane. Background technique [0002] The suspension bridge has a large spanning capacity, can adapt to various terrain conditions, and has a reasonable cost. It is the first choice for engineers to design long-span bridges, especially super-large and super-long-span bridges. Therefore, it also promotes the progress of long-span suspension bridge girder erection technology. And development. For long-span suspension bridges spanning large rivers, rivers, lakes, and seas, people often use cable-mounted cranes or cable cranes to lift the main bridge vertically at fixed points on ships because the main span ranges are all equipped with ship beam transport conditions to varying degrees. For girder installation, there are also methods of hoisting the main girder structure by using a bridge deck crane to assemble from the brid...
