Abstract
The utility model relates to a balancing device for a floating crane. The balancing device for the floating crane comprises a stand column, wherein a lifting arm is hinged with one side of the stand column; a balancing beam is hinged with the top of the stand column; a balancing weight block is arranged at one end of the balancing beam; a balancing pull rod is connected between the other end of the balancing beam and the middle of the lifting arm. The balancing device for the floating crane has the advantages of compact structure, convenience in mounting and low cost; the top of the stand column is hinged with the balancing beam, so that high entire rigidity and high safety coefficient of the lifting arm can be realized through a four-linkage mechanism when the lifting arm is stressed.
Description
Technical field
The utility model 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.
Utility model content
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 scheme that the utility model adopts 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.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, 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 utility model.
Fig. 2 is working state figure of the present utility model.
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 utility model 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 utility model 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 to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, 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).
