Propelled hydraulic cable carrying crane

Abstract

The invention discloses a propelled hydraulic cable carrying crane which comprises a power system, a control system and a mechanical executing mechanism, wherein the mechanical executing mechanism mainly comprises a main truss (100), walking type propelling systems (210 and 220) installed at both ends of the main truss, two sets of hydraulic lifting systems (310 and 320) installed on the main truss and a shoulder pole beam (400); the main truss and the shoulder pole beam both adopt length changeable structures; and the hydraulic lifting systems (310 and 320) comprise synchronous stepping continuous lifting jacks and continuous lifting steel strands (510 and 520). The whole crane realizes walking type propelling on a cable by controlling actions of a walking frame and a sliding end beam so as to alternately bear and alternately walk without additional traction equipment and manual disassembly, assembly and conveying of accessories at high altitude, such as clamping cables, hoops, and the like, and the invention has the advantages of high walking speed, high sliding resistance and high safety.

Description

technical field [0001] The invention relates to a cable-carried crane for mechanized construction equipment of a suspension bridge, in particular to a cable-carried crane capable of self-propelling on the main cable of a suspension bridge. Background technique [0002] With the rapid development of my country's national economy, the construction scale and speed of kilometer-level long-span suspension bridges continue to increase. As a special equipment for suspension bridge girder hoisting, the overall performance of the cable-mounted crane, especially the way of walking on the cable, needs to be improved urgently. . The existing walking systems of hoist type and hydraulic lift type cable-mounted cranes in our country mainly use the wheel group type of walking or the full hydraulic walking type of walking to realize self-walking on the cable, and both require the traction ability of hoist, traction jack and other equipment. Moving on the cable and manually carrying, dismantl...

Problems solved by technology

The existing walking systems of hoist type and hydraulic lift type cable-mounted cranes in our country mainly use the wheel group type of walking or the full hydraulic walking type of walking to realize self-walking on the cable, and both require the traction ability of hoist, traction jack and other equipment. Moving on the cable and manually carrying, dismantling, and installing accessories such as cable clamps and hoops at high altitudes to complete the fixing of the whole machine on the main cable, which will increase the cost and prolong the construction period and be extremely dangerous
