Abstract

The invention belongs to the technical field of water conservancy and hydropower engineering and provides a fixed double-suspending point cantilever track type purlin suspender mainly comprising support legs, cantilever longitudinal beams, a translational transverse beam, a lifting mechanism, a translational traction mechanism, a balancing mechanism and a suspending appliance, wherein the support legs for supporting the two cantilever longitudinal beams are arranged on a gate pier, and the translational transverse beam is spanned on the two cantilever longitudinal beams and is connected with slideways of the cantilever longitudinal beams through slide blocks arranged on the translational transverse beam; the lifting mechanism is installed at both ends of the translational transverse beam; the translational traction mechanism is respectively connected with both ends of the translational transverse beam; and the balancing mechanism is installed at the tails of the cantilever longitudinal beams and is connected with a ground anchor of the gate pier. The fixed double-suspending point cantilever track type purlin suspender is especially suitable for the hoisting construction of dam-crest gantry crane track beams of large-tonnage gate dam type hydropower stations with narrow fields, simple roads, high hoisting height and difficult construction of large-scale hoisting equipment and has the advantages of simple structure, low fabricating cost, convenient operation, strong adaptability to construction sites, high hoisting height and low investment due to the adoption of universal appliances and equipment.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, in particular to a cantilever track-type truss crane with fixed double suspension points. 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. At present, bridge erecting machine and crane schemes are usually adopted, but for dam-type hydropower station projects, the volume and weight of the track girder of the gate crane at the top of the dam are very large, and long-distance transportation is very difficult; the construction site is narrow, the road is simple, and large-scale equipment It is difficult to display and the construction interference is large. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a cantilever track-type truss crane with fixed do...
