In order to achieve the above purpose, the technical solution adopted by the utility model is: a crane anti-swing device, its innovative point is: including a hoisting motor, a reducer, a double drum, a hoisting wire rope, a vehicle frame and a telescopic boom frame, the The lifting motor, the reducer and the double drum are sequentially connected by transmission. The upper end of the telescopic boom is fixedly connected to the crane beam. The telescopic boom includes four-section telescopic steel pipes, and rolling bearings and balancer The rolling bearing and the balancing weight are respectively fixedly connected to the telescopic steel pipes, and the adjacent telescopic steel pipes are flexibly connected through the rolling bearings and the balancing weights.

Further, a safety brake is also included, and the safety brake is arranged on the hoisting wire rope.

Further, an electric control system is also included, and the electric control system is electrically connected with the hoisting motor.

Further, the electric control system is electrically connected with an overload limiter, and the overload limiter is arranged on the vehicle frame.

Further, a wire rope regulator is provided at the position where the hoisting wire rope is in contact with the vehicle frame.

After adopting the above structure, the beneficial effects of the utility model are as follows:

(1) The utility model is provided with a telescopic arm frame, which can be raised and lowered together with the hoisting wire rope in the process of hoisting and lifting, and utilizes the stability of rigid pipe fittings to reduce the shaking of the vehicle frame, thereby increasing safety and stability.

(2) The utility model controls the hoisting weight of the spreader by setting an overload limiter, which is connected to a display screen, so that the lifting operator can see the lifting weight in real time, prevent overloading, and play a role in safe production.

(3) The utility model sets the tension angle of the hoisting wire rope through the wire rope adjuster, and the wire rope adjuster can adjust the angle of the wire rope when the wire rope is lifted and lowered, so as to achieve the smooth effect of the spreader.

Description of drawings

Fig. 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present utility model, and are not intended to limit the present utility model.

Referring to Fig. 1, this specific embodiment discloses a crane anti-swing device, including a hoisting motor 1, a reducer 2, a double drum 3, a hoisting wire rope 9, a vehicle frame 10 and a telescopic boom 7, the hoisting The motor 1, the reducer 2 and the duplex reel 3 are sequentially connected by transmission. The upper end of the telescopic boom 7 is fixedly connected with the crane beam through bolts. The telescopic boom 7 includes four telescopic steel pipes 71, and the telescopic steel pipe 71 Rolling bearings 72 and balance weights 73 are arranged inside, and the rolling bearings 72 and balance weights 73 are fixedly connected with telescopic steel pipes 71 by bolts respectively, and adjacent telescopic steel pipes 71 are flexibly connected by rolling bearings 72 and balance weights 73 .

Feasibly, the hoisting wire rope 9 is provided with a safety brake 4, which can adopt the same specifications as the brake of the wire rope in the prior art. When the spreader is descending, the safety brake 4 is opened, and the four-section telescopic steel pipe 71 of the telescopic boom 7 is opened by the gravity of the spreader. The wire rope goes up and down together, and the stability of the rigid pipe is used to reduce the shaking of the frame, thereby increasing safety and stability. The hoisting wire rope 9 drives the sling and the inner rolling bearing 72 of the telescopic jib 7 to achieve a lifting effect.

One end of the hoisting wire rope 9 is connected to the double drum 3 to transmit power, and one end is installed on the lower part of the wire rope regulator 8. The tension angle between the two ropes of the hoisting wire rope 9 should be ≥ 20°. When the wire rope is lifted and lowered, the wire rope regulator 8 Automatically adjust the angle of the wire rope to achieve the smooth effect of the spreader.

Feasibly, the whole device can also be provided with an electric control system 5 which is electrically connected with the hoisting motor 1 . The electronic control system 5 is electrically connected with an overload limiter 6 , and the overload limiter 6 is arranged on the vehicle frame 10 . The hoisting weight of the spreader is controlled by the overload limiter 6, and the overload limiter is connected to the display screen, so that the hoisting operator can see the lifting weight in real time to prevent overloading and play a role in safe production.

The above is only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model , should be covered in the scope of the claims of the present utility model.
