Abstract
The utility model belongs to the technical field of a crane or a winch, and particularly relates to an anti-swing device for a resistance pulley suitable for a gantry crane. The anti-swing device comprises a pulley and a steel wire rope, wherein the two ends of the steel wire rope bypass the pulley and are fixed on a hanging bracket; the pulley is provided with a brake; the brake comprises at least two brake cylinders arranged on the pulley; the two brake cylinders are respectively arranged at the two sides of the pulley and are used for clamping the pulley; the brake cylinders are used for clamping the pulley by hydraulic or mechanical springs; friction plates are respectively arranged between the brake cylinders with the hydraulic or mechanical springs and the pulley. The anti-swing device can realize the function of preventing the pulley from swinging by adopting the brake cylinders with hydraulic or mechanical spring structures; compared with the existing anti-swing device, the anti-swing device provided by the utility model is simpler in structure, and adopts a brake cylinder structure so as to enable the swinging pulley to be motionless within a short time, thus avoiding the potential safety hazard caused by a weight which is hung under the pulley and swings for a long time.
Description
Technical field
The utility model belongs to hoisting crane or winch technical field, specifically a kind of resistance pulley anti roll device that is applicable to overhead and gantry cranes.
Background technology
At present, hoisting crane all drives the sling liftings such as suspension hook or freight container and realizes loading and unloading operation by the wire rope pulley lifting both at home and abroad, and wire rope pulley adopts roller bearings, and almost few of friction drag, improve mechanical efficiency with this.But, because steel rope does not have resistance, can swing arbitrarily, thereby can't avoid the suspenders such as suspension hook or freight container to rock in the swing of horizontal surface direction, easily collide etc., reduced on the contrary the accuracy of contraposition and the safety of operation.
Existing patent has also been made corresponding patent to wire rope pulley; as number of patent application is 201020175227.7; open day is 2010-12-22; the utility model patent that patent name is " automatically adjusting the equalizer pulley of angle "; its technical scheme is: the utility model relates to a kind of equalizer pulley of automatic adjustment angle, it is characterized in that: comprise equalizer pulley rotating shaft, anti-shake device, equalizer pulley, reel, fixed pulley group, running block; Steel rope passes, finally is suspended on equalizer pulley from reel, running block, fixed pulley group, and equalizer pulley rotating shaft, anti-shake device are set on equalizer pulley, and the anti-shake device is set in the equalizer pulley rotating shaft.
The equalizer pulley of above-mentioned patent just is provided with a kind of pulley that can swing, but this equalizer pulley can only reduce the amplitude of pulley swing to a certain extent, can not make pulley stop swinging immediately, its anti-effect bad of shaking.
Summary of the invention
Thereby realize in order to solve the pulley resistance that can't effectively increase that existing wire rope pulley exists the problem that pulley is stopped swinging immediately, a kind of resistance pulley anti roll device under the prerequisite of the existing special safety that proposes a kind of accuracy that can guarantee contraposition and operation.
For realizing above-mentioned technique effect, the technical solution of the utility model is:
A kind of resistance pulley anti roll device, comprise pulley and steel rope, the two ends of described steel rope are walked around pulley and are fixed on suspension bracket, it is characterized in that: on described pulley, be provided with drg, described drg comprises at least two brake cylinders that are arranged on pulley, and two brake cylinders lay respectively at the both sides of pulley, and clamps pulley, described brake cylinder clamps pulley by hydraulic pressure or mechanical spring, between the brake cylinder of described hydraulic pressure or mechanical spring and pulley, is provided with friction lining.
The distance at described steel rope two ends is identical with diameter of pulley.
The distance at described steel rope two ends is greater than the diameter of pulley.
Described pulley center is provided with for hanging the suspender of weight.
The utility model advantage is:
1, the utility model has adopted the rocking-prevention function of being realized pulley by the brake cylinder of hydraulic pressure or mechanical spring structure, with respect to existing anti roll device, the application's structure is more simplified, and adopted the brake cylinder structure can make at short notice the pulley that waves static, the weight of having avoided the pulley below to hang waves for a long time and produces potential safety hazard.
2, the distance at the utility model steel rope two ends is identical with diameter of pulley, can save like this steel rope taking up room on suspension bracket.
3, the distance at the utility model steel rope two ends is greater than diameter of pulley, although it is larger that it takes up room on suspension bracket, but this structural reinforcing the relative stability of steel rope and pulley, can realize braking at shorter time at the cooperation lower sheave of brake cylinder, the anti-better effects if of shaking.
Figure of description

The structural representation that Fig. 2 is the utility model embodiment 2.
In accompanying drawing: pulley 1, steel rope 2, suspension bracket 3, drg 4, suspender 5.
The specific embodiment
Embodiment 1
A kind of resistance pulley anti roll device comprises pulley 1 and steel rope 2, the two ends of described steel rope 2 are walked around pulley 1 and are fixed on suspension bracket 3, be provided with drg 4 on described pulley 1, described drg 4 comprises at least two brake cylinders that are arranged on pulley 1, two brake cylinders lay respectively at the both sides of pulley 1, and clamping pulley 1, described brake cylinder clamps pulley 1 by hydraulic pressure or mechanical spring, be provided with friction lining between the brake cylinder of described hydraulic pressure or mechanical spring and pulley 1, the distance at steel rope 2 two ends is identical with pulley 1 diameter.When pulley 1 waves, two brake cylinders clamp pulley 1, and 1, the friction lining on brake cylinder and pulley produce friction force, and restriction steel rope 2 moves freely, and produce and prevent shaking resistance, and pulley 1 is remained static fast.The utility model has adopted the rocking-prevention function of being realized pulley 1 by the brake cylinder of hydraulic pressure or mechanical spring structure, with respect to existing anti roll device, the application's structure is more simplified, and adopted the brake cylinder structure can make at short notice the pulley 1 that waves static, the weight of having avoided pulley 1 below to hang waves for a long time and produces potential safety hazard.The distance at steel rope 2 two ends is identical with pulley 1 diameter, can save steel rope 2 taking up room on suspension bracket 3 like this.
Embodiment 2
A kind of resistance pulley anti roll device, comprise pulley 1 and steel rope 2, the two ends of described steel rope 2 are walked around pulley 1 and are fixed on suspension bracket 3, it is characterized in that: on described pulley 1, be provided with drg 4, described drg 4 comprises at least two brake cylinders that are arranged on pulley 1, and two brake cylinders lay respectively at the both sides of pulley 1, and clamps pulley 1, described brake cylinder clamps pulley 1 by hydraulic pressure or mechanical spring, between the brake cylinder of described hydraulic pressure or mechanical spring and pulley 1, is provided with friction lining.The distance at steel rope 2 two ends is greater than the diameter of pulley 1.Described pulley 1 center is provided with the suspender 5 for hanging weight.
