[0003] Marine crane beams are often used in port loading and unloading. Most of the existing marine crane beams are truss-supported marine crane beams. It can be used as a hanging beam very well, but the traditional hanging beam is a hanging beam specially designed for a certain object. The opening is not variable and the size is fixed. When there are objects with larger or smaller lengths At the same time, the mooring cable is difficult to adapt to objects of various sizes, and the scope of adaptation is small, which causes waste to users; at the same time, due to the truss structure, the truss components are bulky, and it is relatively difficult to manufacture and maintain

Embodiment Construction
[0014] In the following, with reference to the accompanying drawings and specific implementation methods, the open crotch variable marine suspension beam of the present invention will be further described in detail.
[0015] As shown in the figure, the open crotch variable marine suspension beam of the present invention includes more than two open crotch stays 1 that can be connected and disassembled with each other. The cross section can be polygonal or circular, and the length of each standard section is The size can be the same or different, and the design can be optimized according to the user's various objects; thus, the open crotch support rod 1 can be a variable open crotch structure, which can be combined in any way to form a hanging beam with different openings to adapt to hanging objects of different sizes Fortunately, the outer ends of the two crotch-opening stays 1 on the left and right sides are respectively provided with upper and lower shackles 2 and 3, so that t...

The invention discloses a jackstay crotch-variable marine hanging beam which comprises more than two crotch jackstays which can be connected to each other and can be disassembled. An upper shackle and a lower shackle are respectively arranged at left and right outmost sides of the two crotch jackstays. The upper shackles at left and right upper ends are respectively connected with hoisting equipment through a steel wire rope. The lower shackles at left and right lower ends are connected with a fastening rope. By the adoption of the above structure, jackstay crotch is variable, and multiple jackstays can be combined at random so as to form hanging beams with different crotches to fit with objects of different sizes for hoisting. According to the invention, present hanging beam structures are simplified; the volume of the hanging beam is minimized; and it is very convenient to manufacture, install and maintain the hanging beam. The hanging beam has a simple structure and requires low cost. By the adoption of the hanging beam, the problem that a large-scale marine hanging beam has a small application range of object sizes is solved. The hanging beam provided by the invention has strong adaptability to objects of different sizes and is especially suitable for hoisting of large-scale marine equipment, such as big-sized and heavy objects (for instance, an offshore wind power tower barrel and a base, etc.).
Description
[0001] technical field [0002] The invention relates to an accessory for lifting equipment, in particular to a variable open crotch type marine suspension beam. Background technique [0003] Marine crane beams are often used in port loading and unloading. Most of the existing marine crane beams are truss-supported marine crane beams. It can be used as a hanging beam very well, but the traditional hanging beam is a hanging beam specially designed for a certain object. The opening is not variable and the size is fixed. When there are objects with larger or smaller lengths At the same time, the mooring cable is difficult to adapt to objects of various sizes, and the scope of adaptation is small, which causes waste to users; at the same time, due to the truss structure, the truss components are bulky, and it is relatively difficult to manufacture and maintain. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a v...
