Abstract

A folding arm hydraulic crane comprises a base; the base is provided with a swing mechanism for controlling the rotation of the crane; the upper part of the base is connected with a tower body through fasteners; the top of the tower body is hinged with a luffing lazy arm; the head of the luffing lazy arm is hinged to a folding arm; the folding lazy arm is provided with a hinge seat; the hinge seat is fixed with a lifting winch; and the lifting winch is connected with a hook through a wire rope. The folding arm hydraulic crane also includes a luffing oil cylinder; the luffing lazy arm is provided inside with a hinge support; one end of the luffing oil cylinder is connected with the tower body, and the other end of the luffing oil cylinder is connected with the hinge support; and a folding oil cylinder is located between the hinge support and the hinge seat. The folding lazy arm occupies small space, and is flexible and reliable for usage. During working, the folding lazy arm is expanded to lift distant goods; and the folding lazy arm is folded when the working stops, so as to greatly reduce the ship space needed by the crane.

Description

Folding arm hydraulic lift

Technical field

The present invention relates to weight-lifting equipment technical field, especially a kind of folding arm hydraulic lift.

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.

Towboat on market of ship, fishing boat, because boats and ships self are not very large, when common deck crane is installed, can take the very most of space of hull, and some towboat, fishing boat just cannot be installed common deck crane because of space constraint at all.

Summary of the invention

The applicant, for the shortcoming in above-mentioned existing production technology, provide a kind of folding arm hydraulic lift rational in infrastructure, thereby it is little that it is taken up room, and structure is light and handy, and installation and use is convenient.

The technical solution adopted in the present invention is as follows:

A kind of folding arm hydraulic lift, comprise base, the swing type mechanism of controlling its rotation is installed on described base, the top of described base is connected with tower body by fastener, the top of described tower body is hinged with luffing arm, and the head of described luffing arm is hinged with folded boom arm, in described folded boom arm, hinge seat is installed, on described hinge seat, be fixed with hoister winch, described hoister winch is by steel rope connecting shackle; Also comprise amplitude oil cylinder, in described luffing arm, be provided with rocker bar bearing, one end of described amplitude oil cylinder is connected with tower body, and the other end of described amplitude oil cylinder is connected with rocker bar bearing; Folding oil cylinder is installed between rocker bar bearing and hinge seat.

Further improvement as technique scheme:

One end of described steel rope is connected with hoister winch, and the other end of described steel rope is walked around assembly pulley successively, the stop gear that hoists, balance block, shackle are connected with suspension hook;

The circular tube structure of described base;

Described tower body becomes body structure;

Described luffing arm adopts steel plate splicing to become box body shape structure;

Described folded boom arm adopts steel plate splicing to become box body shape structure.

Beneficial effect of the present invention is as follows:

Compact conformation of the present invention, rationally, makes with easy for installation, adopts folded boom arm, takes up room little, uses flexibility and reliability, and the boats and ships such as efficient solution towboat, fishing boat cannot be installed a common deck crane difficult problem because of self dimensional problem; It launches folded boom arm in work, and the goods of lifting farther place is folding out-of-run time, has reduced so greatly the required boats and ships space of hoisting crane.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Wherein: 1, base; 2, tower body; 3, luffing arm; 4, swing type mechanism; 5, folded boom arm; 6, rocker bar bearing; 7, hinge seat; 8, the stop gear that hoists; 9, balance block; 10, hoister winch; 11, steel rope; 12, shackle; 13, suspension hook; 14, amplitude oil cylinder; 15, folding oil cylinder.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, the folding arm hydraulic lift of the present embodiment, comprise base 1, the swing type mechanism 4 of controlling its rotation is installed on base 1, and the top of base 1 is connected with tower body 2 by fastener, and the top of tower body 2 is hinged with luffing arm 3, the head of luffing arm 3 is hinged with folded boom arm 5, hinge seat 7 is installed in folded boom arm 5, is fixed with hoister winch 10 on hinge seat 7, hoister winch 10 is by steel rope 11 connecting shackles 13; Also comprise amplitude oil cylinder 14, be provided with rocker bar bearing 6 in luffing arm 3, one end of amplitude oil cylinder 14 is connected with tower body 2, and the other end of amplitude oil cylinder 14 is connected with rocker bar bearing 6; Folding oil cylinder 15 is installed between rocker bar bearing 6 and hinge seat 7.

One end of steel rope 11 is connected with hoister winch 10, and the other end of steel rope 11 is walked around assembly pulley successively, the stop gear 8 that hoists, balance block 9, shackle 12 are connected with suspension hook 13.

The stop gear 8 that hoists is mainly used for limiting goods safety distance between goods and folded boom arm 5 under the state of hoisting, and prevents that goods from colliding folded boom arm 5.

The round plate that balance block 9 is constant weight, is mainly used in suspension hook 13 when not lifting goods, because deadweight problem steel rope 11 is difficult to the problem of below.

The circular tube structure of base 1.

2 one-tenth body structures of tower body.

Luffing arm 3 adopts steel plate splicing to become box body shape structure.

Folded boom arm 5 adopts steel plate splicing to become box body shape structure.

In actual use procedure, by amplitude oil cylinder 14, control the action of luffing arm 3, by folding oil cylinder 15, control the work of folded boom arm 5.In the time of need to working, folded boom arm 5 is stretched out work, and while not needing work, folded boom arm 5 is folding, saves space.

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.
