Description

Marine crane with fixing device

Technical Field

The utility model relates to the field of mechanical equipment, especially, relate to a take fixing device's marine crane.

Background

Marine cranes are used to lift heavy objects on deck. The ship crane in the prior art is basically the same as various cranes used on land and comprises a rotating platform, a crane boom, a steel rope and a hook, wherein the rotating platform controls the crane boom to rotate, the steel rope is wound on a fixed pulley at the tail end of the crane boom, two ends of the steel rope are respectively connected with the hook and a winding drum, and the steel rope is continuously wound after the winding drum rotates, so that the function of taking off and landing the hook is achieved. Because the hull floats on the water, the rocking of the water surface can cause the hull and the marine crane to rock synchronously, so that the marine crane in the prior art can cause the goods to rock more easily in comparison with a land crane during working.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a take fixing device's marine crane utilizes the displacement of montant restriction couple in the horizontal plane, reduces rocking of goods.

In order to solve the technical problem, the utility model discloses a technical scheme does: a marine crane with a fixing device comprises a rotating platform, a crane boom, a sleeve, a vertical rod, a first rope, a lifting frame, a second rope and a hook;

the lifting frame is arranged on the rotating platform, two sides of the tail end of the lifting frame are respectively hinged with a sleeve, a vertical rod penetrates into each sleeve, the vertical rods can freely penetrate into the sleeves, the tail end of each vertical rod is fixedly connected with the lifting frame, and the lifting frame is connected with the lifting frame and the winding drum through a first rope;

the hook is connected with the lifting frame through a second rope, and the length of the second rope is far smaller than that of the first rope.

When the marine crane works, the lifting frame is driven by the winding drum to move up and down, and the vertical rod moves up and down synchronously along with the lifting frame; compared with the traditional crane hook which can freely swing in a horizontal plane, the crane of the utility model can only swing with a small degree in a single direction along with the sleeve because the crane is clamped by the vertical rod, thereby greatly reducing the swing freedom of the crane; correspondingly, the swinging freedom degree of the hook connected with the lifting frame is reduced, and the swinging amplitude of goods lifted on the hook is effectively reduced.

Generally, when the marine elevator is used, the position of the hook and the position of goods are difficult to align accurately; therefore, the utility model discloses with crane and couple separation, utilize the second rope to connect crane and couple for the couple has certain swing ability, makes things convenient for the workman to be connected couple and goods.

Furthermore, a plurality of rollers are arranged in the sleeve, and the vertical rod is positioned between the rollers; the roller is used for avoiding the montant and sleeve pipe to produce sliding friction.

Further, the rollers are evenly distributed around the central axis of the sleeve.

Further, the marine crane also comprises a cross rod, and two ends of the cross rod are respectively connected with the tops of the two vertical rods; the horizontal pole can be spacing to two montants, avoids montant downward displacement too big and leads to montant and sleeve pipe to break away from.

Furthermore, the tail end of the crane boom is provided with a limiting column which is positioned at two sides of the sleeve; because the sleeve pipe is articulated with the jib loading boom, consequently the sleeve pipe can freely swing, and spacing post is used for the angle of restriction sleeve pipe free swing.

Furthermore, the both sides of crane respectively set up the connecting rod of an L shape, and the end of connecting rod inserts the end of montant, and the montant end is provided with radial fixing bolt, and fixing bolt fastens montant and connecting rod.

Has the advantages that: (1) the utility model discloses a take fixing device's marine crane respectively fixes a montant in the both sides of crane, utilizes the sleeve pipe to entangle the montant to the realization is injectd the position of crane, very big reduction the swing ability of crane in the horizontal plane, thereby reach the function that reduces couple and goods and rock. (2) The utility model discloses a take fixing device's marine crane separates crane and couple, utilizes the second rope to connect crane and couple for the couple has certain swing ability, makes things convenient for the workman to be connected couple and goods. (3) The utility model discloses a take fixing device's marine crane sets up a plurality of gyro wheels at the sleeve pipe, with the montant centre gripping between the gyro wheel, avoids montant and sleeve pipe to produce sliding friction, reduces the wearing and tearing of montant in the course of the work, improves marine crane's life. (4) The utility model discloses a take fixing device's marine crane sets up spacing post at the end of jib loading boom, further limits the swing ability of montant in the restriction sheathed tube, reaches the function that reduces couple and goods and rock.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1 to 5, the marine crane with a fixing device of the present embodiment includes a rotating platform 1, a boom 2, a sleeve 3, a vertical rod 4, a first rope 5, a crane 6, a second rope 7, a hook 8 and a cross rod 9;

the crane boom is characterized in that the crane boom 2 is arranged on the rotating platform 1, two sides of the tail end of the crane boom 2 are respectively hinged with a sleeve 3, a vertical rod 4 penetrates into each sleeve 3, the vertical rods 4 can freely penetrate into the sleeves 3, a plurality of rollers 10 are arranged in the sleeves 3, the rollers 10 are uniformly distributed around the central axis of the sleeves 3, and the vertical rods 4 are positioned between the rollers 10; the tail end of the crane boom 2 is provided with a limiting column 11, and the limiting columns 11 are positioned at two sides of the sleeve 3;

the two ends of the cross rod 9 are respectively connected with the tops of the two vertical rods 4;

the crane 6 is connected with the crane arm 2 and the winding drum through a first rope 5, the two sides of the crane 6 are respectively provided with an L-shaped connecting rod 12, the tail end of the connecting rod 12 is inserted into the tail end of the vertical rod 4, the tail end of the vertical rod 4 is provided with a radial fixing bolt 13, and the fixing bolt 13 fastens the vertical rod 4 and the connecting rod 12;

the hook 8 is connected with the lifting frame 6 through a second rope 7, and the length of the second rope 7 is far smaller than that of the first rope 5;
