Description

Technical Field

[0001] The utility model relates to the technical field of crane machinery, in particular to a disassembly-free hook head pushable device for a crane lying rod or a lifting rod. Background Art

[0002] Crawler cranes are a type of heavy lifting equipment widely used in construction, shipbuilding, petrochemicals, electric power, marine engineering and other fields. The installation, maintenance and disassembly of super-large equipment and modular structures place higher demands on lifting capacity and working range. Tower-type operations are frequently required in the later stages of the project. When performing tower-type operations, the crane needs to perform boom lifting or boom lowering operations for daily maintenance and typhoon prevention during typhoon season. Daily boom lowering maintenance and typhoon prevention operations are very time-sensitive. Traditional boom lifting or boom lowering operations usually require disassembly of the hook, recovery and threading of the wire rope, which not only increases the complexity and time cost of the operation, but also may bring safety risks.

[0003] The tower-type working condition lowering boom operation process: 1. Make preparations for adding super-lifting counterweight, etc.; 2. Operate the control handle and lower the jib head close to the ground under the command of the commander; 3. Remove the eagle's beak and small hook; 4. Remove the rope stop rod, limiter, and belt rope head connector of the large hook pulley group; 5. Pull out the auxiliary winch wire rope and connect it to the large hook wire rope head, operate the auxiliary winch and the large hook winch synchronously, and retract the steel wire passed through the large hook pulley group; 6. Place the jib head on the lowering boom trolley, and operate the handle to lower the boom to the ground pad. The tower-type working condition raising boom operation process is opposite to the lowering boom operation sequence. The crawler crane tower working condition raising boom operation is complicated and inefficient, and may also bring safety risks to equipment and personnel. The whole process is time-consuming and labor-intensive. For this reason, we propose a movable device for crane lowering boom or raising boom without removing the hook head. Utility Model Content
