Embodiment 1

[0019] Such as Figure 1-2 As shown, a center of gravity lifting type crane anti-sway device includes a support frame 1, a lifting mechanism 2, a running trolley 3 and a sling 4, an anti-sway frame 5 is provided under the running trolley 3, and the upper end of the sling 4 is connected to the anti-sway The inner top surface of the rocking frame body 5 is fixedly connected, and the lower end of the running trolley 3 is fixedly connected with two L-shaped connecting rods 6, and a fixed wheel 7 is fixedly installed between the two L-shaped connecting rods 6, and the fixed wheel 7 is located at the In the rocking frame body 5 and parallel to the anti-rolling frame body 5, a rotating ring 8 is connected to the outer ring side wall of the fixed wheel disc 7, and balls are arranged between the fixed wheel disc 7 and the rotating ring 8, so that the sliding friction becomes Rolling friction reduces friction consumption and prolongs its service life. The lower end of the rotating ring ...

Embodiment 2

[0023] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the rotating ring 8 is composed of two semi-circular rings 11, the semi-circular ring 11 located below is made of magnetic material, and the inner top surface of the anti-rolling frame 5 A permanent magnet block 12 is fixedly installed, and the same polarity repels each other between the permanent magnet block 12 and the semi-circular ring 11 .

[0024] In this embodiment, when the sling 4 and the heavy object are not swinging, the permanent magnet block 12 is far away from the magnetic semi-circular ring 11, and when the heavy object drives the sling 4 to swing, it drives the rotating ring 8 to rotate, The magnetic semi-circular ring 11 located at the bottom rotates to a higher position and approaches the direction of the permanent magnet block 12, that is, when the sling 4 swings, it needs to overcome the repulsive force between the permanent magnetic block 12 and the semi-circu...

Abstract

The invention belongs to the field of crane accessories, and particularly relates to a gravity center lifting crane anti-sway device. The gravity center lifting crane anti-sway device includes a support frame, a lifting mechanism, a running trolley and a sling; an anti-sway frame is arranged under the running trolley; the upper end of the sling is fixedly connected to the inner top surface of theanti-sway frame; two L-shaped connecting rods are fixedly connected to the lower end of the running trolley; a fixed wheel disc is fixedly installed between the two L-shaped connecting rods; the fixedwheel disc is located in the anti-sway frame and arranged in parallel with the anti-sway frame; a rotating ring is rotatably connected to the side wall of the outer ring of the fixed wheel disc; thelower end of the rotating ring is provided with a segment of tooth groove; a rack is fixedly connected to the outside of the sling; the rack meshes with the lower end of the rotating ring; and both sides of the rotating ring are provided with ratchet teeth. The gravity center lifting crane anti-sway device can convert the kinetic energy and inertial potential energy of a weight swinging upward dueto inertia and wind into gravitational potential energy, so that the swinging energy is quickly converted and consumed, and a good anti-sway effect is realized.

Description

technical field [0001] The invention belongs to the field of crane accessories, in particular to a center-of-gravity lifting type crane anti-sway device. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. The working characteristics of lifting equipment are intermittent movements, that is, the actions of taking, moving, and unloading in a working cycle. The corresponding mechanisms work alternately, and the development and use of cranes in the market are becoming more and more extensive. [0003] When the existing crane lifts heavy objects, the heavy objects will swing back and forth in the plumb plane due to the inertial force and horizontal wind load. If the heavy object swings too much, the suspension may not be firm, and there is a greater safety hazard. Hidden dangers; at the same time, the swinging heavy objects are not easy to land, and when the heavy ...
