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
The present invention relates to weight-lifting equipment technical field, especially a kind of floating crane balancing device.
Background technology
Deck crane, is a kind of large deck machinery on ship, and it is a kind of equipment of ship loading and unloading goods.
The floating crane of rigidity luffing, when luffing, because the arm of force is smaller, when pulling suspension arm variable-amplitude, the power that tooth bar is subject to is larger, if tooth bar fracture can cause arm to drop, causes the accident.The safety performance of entire machine will decline greatly like this, and has potential safety hazard.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of floating crane balancing device rational in infrastructure, thereby improves hoisting crane integral rigidity intensity, improves safety factor.
The technical solution adopted in the present invention is as follows:
A kind of floating crane balancing device, comprise column, a side of described column is hinged with arm, and the top that is positioned at column is hinged with equalizing bar, one end of described equalizing bar is provided with equilibrate counterweight, between the other end of described equalizing bar and arm middle part, is connected with balancing pull rod.
Further improvement as technique scheme:
The middle part of described equalizing bar is articulated with the top of column.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, easy for installation, cost is low, and by the hinged balance beam action in the top at column, and by the effect of four-bar linkage, while making arm stressed, integral rigidity is high, and the safety factor of arm is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is working state figure of the present invention.
Wherein: 1, equilibrate counterweight; 2, equalizing bar; 3, column; 4, balancing pull rod; 5, arm.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the floating crane balancing device of the present embodiment, comprise column 3, one side of column 3 is hinged with arm 5, the top that is positioned at column 3 is hinged with equalizing bar 2, one end of equalizing bar 2 is provided with equilibrate counterweight 1, between the other end of equalizing bar 2 and arm 5 middle parts, is connected with balancing pull rod 4.
The middle part of equalizing bar 2 is articulated with the top of column 3.
The present invention is according to the principle of balance, and when pulling arm 5 to do luffing action, equilibrate counterweight 1 is also given the corresponding power of arm 5, thereby has alleviated the burden of the tooth bar that pulls arm 5 work.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
Claims (2)
1. a floating crane balancing device, it is characterized in that: comprise column (3), one side of described column (3) is hinged with arm (5), the top that is positioned at column (3) is hinged with equalizing bar (2), one end of described equalizing bar (2) is provided with equilibrate counterweight (1), between the other end of described equalizing bar (2) and arm (5) middle part, is connected with balancing pull rod (4).
