Problems solved by technology
At present, steel wire rope luffing is mostly used. The steel wire rope luffing fixed hoist is light in weight, has no rigid luffing related hinge points, and the jib is easy to install, but the operating efficiency is low.
Rigid luffing fixed cranes such as rack luffing and oil cylinder luffing are more efficient than wire rope luffing fixed cranes, but they are limited to rigid luffing drive mechanisms. The height is high, and if it is used for on-board operations, the stability of the ship is poor, especially in transportation or storm conditions, there is a great safety hazard
The installation of the boom and related hinge points takes a lot of time. If you want to disassemble the boom, you need to use special lifting equipment for disassembly; when you use it, you also need special lifting equipment for installation, which costs a lot

The invention discloses a single-arm frame fixing hanger and an arm frame hinge point installing method. The single-arm frame fixing hanger solves the problems that in the prior art, a single-arm fixing hanger is complex to assemble and disassemble and has the beneficial effects of being convenient to install and free of restriction of auxiliary operation conditions. According to the scheme, the single-arm frame fixing hanger comprises a stand column serving as a rack. The side portion of the stand column is provided with an arm frame. The top of the stand column is provided with a balancing beam connected with the stand column in a hinged manner. The end of the balancing beam and the arm frame are connected through a small pulling rod. The stand column, the balancing arm, the arm frame and the small pulling rod form a balancing system four-rod mechanism. A rotating pair of the balancing system four-rod mechanism comprises a hinge point of the balancing beam and the stand column, the hinge point of the small pulling rod and the balancing beam, the hinge point of the small pulling rod and the arm frame, and the hinge point of the arm frame and the stand column. The stand column is provided with a rack amplitude change mechanism which comprises an amplitude change rack. The amplitude change rack has one amplitude change rack hinge point. The stand column is provided with a portal frame used when the arm frame hinge point is installed, and the amplitude change rack is detachably connected with the portal frame.
Description
technical field [0001] The invention relates to the field of cranes, in particular to a single jib fixed crane and a method for installing a jib hinge point. Background technique [0002] At present, conventional fixed cranes include wire rope luffing, rack luffing, oil cylinder luffing and other forms. At present, steel wire rope luffing is mostly used. The steel wire rope luffing fixed hoist is light in weight, has no rigid luffing related hinge points, and the boom is easy to install, but the operating efficiency is low. Rigid luffing fixed cranes such as rack luffing and oil cylinder luffing are more efficient than wire rope luffing fixed cranes, but they are limited to rigid luffing drive mechanisms. The height is high, and if it is used for onboard operations, the stability of the ship is poor, especially in transportation or storm conditions, there is a great potential safety hazard. The installation of the jib and related hinge points takes a lot of time. If you wa...
