Problems solved by technology
[0002] The existing cable-loaded cranes are all fixed-point hoists to erect steel beams, that is, the steel beams must be transported directly below the cable-loaded cranes before they can be hoisted, and the cable-loaded cranes cannot move after lifting the steel beams
With the construction of long-span suspension bridges in my country, especially in coastal, mountainous, canyon and other areas with poor geographical conditions, affected by geographical conditions, steel girders may not be directly transported to the bottom of the cable-loaded crane, and steel girders cannot be erected construction

Embodiment
[0013] When hoisting and walking, first clamp the cable clamping device with the main cable, and push the traveling cylinder to make the traveling frame move forward on the sliding traveling system. After the cylinder is pushed in place, the stopper and the slideway are connected and fixed by a pin. To prevent the traveling frame from sliding down, untie the connection between the traveling cylinder support and the slideway, retract the traveling cylinder and connect it with the slideway through a pin to complete a traveling action. This kind of cyclic action realizes the walking type walking of the crane. When the walking frame crosses a section of slideway, use the crane on the main truss to transfer the rear slideway to the front for installation. When the cable-carried crane travels through the cable clamp, the position of the cable clamp device is adjusted so that the slideway avoids the cable clamp.

The invention discloses a hydraulic travelling-pedrail type cable crane capable of travelling with load. The cable crane comprises a main truss, a hydraulic lifting system and a travelling-pedrail type travelling system, wherein the travelling-pedrail type travelling system consists of a multiple-section slide way, a travelling cylinder, a travelling frame, a stopper and a cable clamping device; the upper part of the travelling frame is hinged with the main truss; the lower part of the travelling frame slides on the slide way; the lower part of the slide way is supported on a main cable through the cable clamping device and can be clamped with the main cable; the travelling frame is connected with the slide way through the travelling cylinder and can slide on the slide way; and the top parts of the two ends of the main truss are respectively provided with a miniature crane which can be used for transferring cargoes in front of and behind the slide way. The cable crane can be used for realizing the function of travelling on the main cable of a suspension bridge after craning a steel beam; and the cable crane can automatically move to a steel beam erecting position in a travelling-pedrail type travelling way without external traction after taking a beam on the shore.
Description
Technical field [0001] The invention relates to a cable-carrying crane for mechanized construction equipment of a suspension bridge, in particular to a cable-carrying crane capable of running on the main cable of the suspension bridge. Background technique [0002] The existing cable cranes are all fixed-point hoisting and erecting steel beams, that is, the steel beams must be transported directly below the cable crane to be lifted, and the cable crane cannot move after the steel beam is lifted. With the construction of long and long-span suspension bridges in my country, especially those in areas with poor geographic conditions such as coastal, mountainous, canyons, etc., due to geographical conditions, steel beams may not be transported directly under the cable crane, and steel beam erection cannot be carried out. construction. Summary of the invention [0003] The purpose of the present invention is to provide a hydraulic walking type cable crane with load, which realizes t...
