Embodiment Construction
[0050] The technical scheme of the present invention is further described below in conjunction with specific embodiment, but it is not limited thereto:
[0051] The fixed double suspension point cantilever rail type truss crane includes: outriggers, cantilever longitudinal beams, translational beams, lifting mechanisms, translational traction mechanisms, balance mechanisms, and spreaders. The four outriggers support two cantilever longitudinal beams respectively It is placed at the designed position on the top surface of two adjacent gate piers; the translation beam straddles the two cantilever longitudinal beams and contacts with the slideway of the cantilever longitudinal beam through its slider; the two sets of lifting mechanisms are respectively installed on the translation The two ends of the longitudinal beam lift the door machine track beam; the two sets of translational traction mechanisms pull the two ends of the translational beam to move horizontally on the slideway ...

The invention belongs to the field of water conservancy and hydroelectricity engineering, and provides a method for hoisting a gantry crane rail beam in gate dam type hydropower station engineering. The hoisting method mainly comprises five parts, namely translation of a rail beam foundation pit, installation of a fixed double-hoisting point cantilever trail type truss crane, hoisting of the railbeam, transfer of the fixed double-hoisting point cantilever trail type truss crane and translation of the gate pier top of the downstream gantry crane rail beam. The hoisting method provided by the invention has the following advantages: 1, the fixed double-hoisting point cantilever trail type truss crane has simple structure, low manufacturing cost, convenience for operation, strong construction field adaptability and high hoisting height; 2, the method is suitable for local conditions, and has simple construction process and low construction cost; 3, general tools and equipment are used, so the equipment investment is low; and 4, the construction period is shortened.
Description
technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to a hoisting method for a portal crane track beam in a gate dam type hydropower station project. Background technique [0002] For the construction of the dam-type hydropower station, it is inevitable to encounter the problem of hoisting the track beam of the dam crest portal crane. Of course, bridge erecting machine and crane schemes can be adopted, but for the dam-type hydropower station project, the track girder of the gate crane at the dam crest is very large in size and weight, and long-distance transportation is very difficult; the construction site is narrow and the roads are simple, and it is difficult to deploy large-scale equipment And there is a lot of construction interference. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a method for hoisting the track...
