Embodiment Construction
[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0011] The working principle of the medium and high-speed cable machine system of the present invention is the same as that of the prior art, and reference can be made to the prior art, so it will not be described again. The difference between the present invention and the prior art is that the layout structure of the medium and high-speed cable machine system is different, which will be described in detail below:
[0012] Such as figure 1 , 2 Shown, the arrangement structure of the high-speed cable crane system of the narrow valley high steep abutment concrete dam of the present invention, the medium-speed cable crane system includes the cross-river cable 1 of the running crane, and the abutment 9 on one side is used for fixing the cross-river cable The fixed end 2 of the cable machine at one end, the mobile end 12 of the cable machine locate...

The invention discloses an arrangement form for a medium / high-speed cable crane system in a narrow valley high-steep dam abutment concrete dam. The medium / high-speed cable crane system comprises a river-cross cable for operating a crane, a cable crane fixing end which is positioned on the dam abutment on one side and is used for fixing one end of the river-cross cable, a cable crane moving end positioned on the dam abutment on the other side, and a host machine room equipped with host traction equipment, wherein the cable crane fixing end is fixed on the outer side of a short flat hole which is formed in the upper part of the dam abutment in an excavating manner; the host machine room is arranged under the ground through a guide silo which is arranged below the cable crane fixing end; and the host traction equipment is connected with a guide system fixed at the cable crane fixing end through the guide silo, so that the cable crane is operated. The overall arrangement is simple, the influence on the overall stability of a high-steep dam abutment is small, and the influence on the environment is small. The technical problems of high slope stabilization, excavation, support, environment friendliness and the like are solved, the engineering quantity is greatly reduced, and the engineering investment is saved.
Description
technical field [0001] The present invention relates to the arrangement structure of the medium and high speed cable crane system, specifically, it is suitable for the river sections of high mountains and canyons, and it is not suitable for large-scale excavation or excavation to form super high slopes, which will bring stability of high slopes and large engineering quantity. Arrangement structure of medium and high speed cable crane system for high and steep abutment concrete dam in narrow valley and other technical problems. Background technique [0002] At present, in domestic and foreign hydropower projects, medium and high-speed cable cranes are generally arranged in a translational or radial arrangement. According to the mechanical characteristics and operation requirements of the high-speed traction system, the radial cable machine room is generally arranged on the ground directly below the fixed end, and a certain width of the layout site between the barrage and the ...
