Problems solved by technology

[0003] For the rigid luffing floating crane, because the force arm is relatively small during the luffing, when the jib is pulled to luff, the force on the rack is relatively large. If the rack breaks, the jib will fall and cause an accident.
In this way, the safety performance of the whole machine will be greatly reduced, and there are potential safety hazards.

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 and figure 2 As shown, the balance device for the floating crane in this embodiment includes a column 3, a boom 5 is hinged on one side of the column 3, a balance beam 2 is hinged on the top of the column 3, and a balance weight is provided at one end of the balance beam 2 Block 1, a balance tie rod 4 is connected between the other end of the balance beam 2 and the middle part of the boom 5 .

[0016] The middle part of the balance beam 2 is hinged on the top of the column 3 .

[0017] The present invention is based on the principle of balance, and when pulling the boom 5 to perform luffing action, the balance counterweight 1 also gives a corresponding force to the boom 5, thereby reducing the burden on the rack that pulls the boom 5 to work.

[0018] The above description is an explanation of the present invent...

Abstract

The invention relates to a floating crane balancing device. The device comprises a column, a lifting arm is hinged on one side of the column, a balancing beam is hinged on the top part of the column, one end of the balancing beam is provided with a balancing weight block, and the other end of the balancing beam is connected to the middle part of the lifting arm through a balancing pull rod. The floating crane balancing device has the advantages of compact structure, convenient installation, and low cost; a balancing beam is hinged on the top part of the column, a four-bar linkage mechanism is added at the same time, so the integral rigidness is high when the lifting arm is stressed, and the safety coefficient of the lifting arm is high.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a balancing device for a floating crane. Background technique [0002] A marine crane is a large deck machinery on a ship, and it is a device for loading and unloading cargo on a ship. [0003] For the rigid luffing floating crane, because the force arm is relatively small during luffing, the rack is subjected to a large force when pulling the jib to luff, and if the rack breaks, the jib will fall and cause an accident. The safety performance of the whole machine will be greatly reduced like this, and there is a potential safety hazard. Contents of the invention [0004] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a balancing device for a floating crane with a reasonable structure, thereby improving the overall rigidity of the crane and improving the safety factor. [0005] The technical scheme adopted in...
