The basic arm is internally provided with a slide way, and the sliding arm and the telescopic arm of the straight arm crane respectively slide relative to the basic arm through the slide way.

The end of each claw is provided with a self-adaptive clamping piece, and the self-adaptive clamping pieces are hinged with the claws through pin shafts.

The straight arm crane is installed on a base through a slewing support, and the base is an automobile chassis, a deck of a ship or a base provided with supporting legs.

Advantageous effects of the utility model

According to the utility model, the clamping mechanism is added on the basis of the existing straight arm crane, in the process of hoisting a heavy object by the straight arm crane through the steel wire rope, the sliding arm stretches in the basic arm to control the position of the folding arm, then the heavy object is clamped by the actions of the clamping jaw seat, the clamping jaw and the self-adaptive clamping piece, and the self-adaptive clamping piece automatically rotates and adjusts according to the appearance of the heavy object, so that the clamping of the heavy object is ensured. Under the cooperation of the straight arm crane and the clamping mechanism, the stability and the reliability of the hoisting process are improved, and the heavy objects can not shake in the moving process.

Detailed Description

As shown in fig. 1 and 2: the crane with the anti-shake function comprises a base 3, a straight arm crane 2 and a clamping mechanism 1. The straight arm crane 2 comprises a slewing bearing 26, a winch 25, a slewing bearing 24, an amplitude-variable oil cylinder 23, a basic arm 22, a telescopic arm 21, a telescopic arm oil cylinder 29 and a guide wheel 27, wherein the slewing bearing 26 is arranged on a base 3, and the base 3 is an automobile chassis, a deck of a ship or a base provided with supporting legs. The clamping mechanism 1 comprises a plurality of driving oil cylinders, and a sliding arm 18, a folding arm 11, a jaw seat 13 and a jaw 14 which are connected in sequence in a rotating mode. The slewing bearing 24 is mounted on the slewing bearing 26, and the slewing bearing 26 drives the slewing bearing 24 mounted thereon to rotate through gear transmission under the action of a driving member of the slewing bearing. The basic arm 22 is rotatably connected with the slewing bearing 24 through a pin shaft, two ends of the amplitude-variable oil cylinder 23 are respectively hinged with the slewing bearing 24 and the basic arm 22, the basic arm 22 is driven to rotate relative to the slewing bearing 24, a slideway is arranged in the basic arm 22, and the telescopic arm 21 and the sliding arm 18 are respectively in sliding fit with the basic arm 22 through the slideway. The cylinder barrel of the telescopic arm cylinder 29 is connected in the telescopic arm 21 through a middle ear plate, and the cylinder rod of the telescopic arm cylinder 29 is connected on the basic arm 22 through a single ear plate, so that the telescopic arm cylinder 29 and the basic arm 22 are driven to slide relatively. The cylinder barrel of the sliding arm cylinder 18 is connected to the basic arm 22 through a middle ear plate, and the cylinder rod of the sliding arm cylinder 19 is connected to the sliding arm 18 through a single ear plate to drive the sliding arm 18 to slide relative to the basic arm 22. The two ends of the folding arm cylinder 17 are respectively connected to the folding arm 11 and the sliding arm 18 through pin shafts, and drive the folding arm 11 and the sliding arm 18 to rotate relatively. The jaw seat 13 is connected to the folding arm 11 through a pin shaft, and two ends of the jaw seat cylinder 12 are respectively hinged to the folding arm 11 and the jaw seat 13 to drive the folding arm 11 and the jaw seat 13 to rotate relatively; the clamping jaw 14 is connected to the clamping jaw seat 13 through a pin shaft, and two ends of the clamping cylinder 16 are hinged to the clamping jaw 14 and the clamping jaw seat 13 through pin shafts, so that the clamping position of the weight 4 is controlled. The self-adaptive clamping piece 15 is arranged on the clamping jaw 14 through a pin shaft, and automatically adjusts the rotating angle according to the shape of the weight, so that the self-adaptive clamping piece is suitable for the requirement of clamping the weight 4, and the clamping stability is ensured. The windlass 25 is arranged on the slewing bearing 24, and a steel wire rope 28 extending out of the windlass 25 passes through three groups of guide wheels 27 to the front end of the telescopic arm 21 for hoisting the weight 4.

As shown in fig. 3: after the steel wire rope 28 is connected with the weight 4, the clamping mechanism 1 acts, the clamping claw 14 clamps the weight 4 through the self-adaptive clamping piece 15, the straight arm crane 2 lifts the weight 4, and after the shake-free horizontal movement is completed, the weight 4 is placed at a required position. Since the clamping mechanism 1 clamps the weight 4 firmly in the whole lifting process, the weight 4 does not shake in the moving process.

As shown in fig. 4: the basic arm 22, the folding arm 11 and the clamping jaw 14 are all in a horizontal state, and the appearance of the folded novel box is similar to that of a box body, so that the novel box is convenient to transport and store.
