Description
Technical field
The utility model relates to lifting technical field, particularly a kind of anti-sway device for hoisting crane.
Background technology
Current hoisting crane is all adopt steel rope to walk around pulley, drives suspension hook or sling lifting to realize lifting operation by pulley lifting.In hoisting process, particularly when suspension hook or suspender are positioned at bottom, because the length of steel rope release is longer, when being subject to External Force Acting by hoisting object: when being such as subject to wind or collision, by the swing that hoisting object easily occurs by a relatively large margin; Or when too fast by the horizontal direction moving velocity of hoisting object, under effect of inertia, by the swing that hoisting object also easily occurs by a relatively large margin, cause by hoisting object in hoisting process easily and other equipment or object collide, cause whole hoisting process and dangerous, too increase contraposition difficulty simultaneously, increase position aligning time, reduce lifting efficiency.
So, need badly a kind of for hoisting crane at present, can effectively prevent from being waved by lifting object the device rocked.
Summary of the invention
The purpose of this utility model is for current crane structure above shortcomings, provides a kind of for hoisting crane, can effectively prevent from being waved by lifting object the device rocked.
To achieve these goals, the technical solution adopted in the utility model is:
For an anti-sway device for hoisting crane, include the pulley base of pulley and the described pulley of support, described pulley base is arranged on the suspender of hoisting crane, described pulley base is provided with the brake equipment for braking pulley.In studying for a long period of time, contriver finds, the pulley structure of current hoisting crane, the brake gear braked pulley is not set, in hoisting process, self inertia effect is subject to by hoisting object, or during External Force Acting, swung by hoisting object, now pulley rolls on a steel cord with the swing by hoisting object, and owing to being friction of rolling between pulley and steel rope, its friction force produced is less, enough large resistance can not be produced to pulley, and then can not reduce by the amplitude of fluctuation of hoisting object by actv., in the utility model, brake equipment is set, when being had swing by a relatively large margin by hoisting object, start brake equipment to brake pulley, now, friction of rolling between pulley and steel rope becomes cliding friction, directly increase the friction force between steel rope and pulley, make, pulley can only slide on a steel cord with by the swing of hoisting object, original friction of rolling is become cliding friction, improve the friction force between pulley and steel rope greatly, and then larger resistance is produced to the slip of pulley, reach the object reduced gradually by hoisting object amplitude of fluctuation, and then effectively prevent and rocked by waving of hoisting object, improve the safety in hoisting process, and reduce the difficulty of suspender contraposition, improve lifting efficiency.
As preferably, described brake equipment includes bracing frame and brake disc, support frame as described above is arranged on described pulley base, described brake disc matches with described pulley, be provided with retractor device between support frame as described above and described brake disc, described retractor device controls described brake disc and compresses or depart from described pulley.Control being adjacent to and being separated of brake disc and pulley by retractor device, realize the braking of brake disc to pulley.
As preferably, described brake disc is positioned at the top of described pulley, and described brake disc matches with the circular arc rim of described pulley the first half, and described retractor device is along the radial expansion of described pulley.Compressed by retractor device promotion brake disc and pulley or departed from, realizing the braking to pulley, owing to fitting in the edge of brake disc and pulley, comparatively other positions, can produce maximum braking force, improve braking effect, ensure reliability during braking.
As preferably, described pulley base is also provided with holding device, described holding device includes the holding part for clamped wire rope, and drives the actuating device of described holding part folding, and described holding part is normally open.Although brake disc can brake sheave, but pulley still can slide with the swing by hoisting object on a steel cord, so pass through holding device, when placing by hoisting object in translation or contraposition, holding part clamping is driven on a steel cord by actuating device, relative position between pulley base and steel rope is fixed, the relative position between pulley and steel rope is directly made to be fixed, further reduction is by the amplitude of fluctuation of hoisting object, and can make to be returned to quiescence by hoisting object fast speed in swing, further effectively prevent from being rocked by waving of hoisting object, improve the safety in hoisting process, reduce contraposition difficulty, improve lifting efficiency.
As preferably, described holding device is two, one of them holding device is corresponding with the steel rope of described pulley side, and another holding device is corresponding with the steel rope of described pulley opposite side, and two described holding devices match with each self-corresponding steel rope respectively.Arrange two holding devices, after steel rope walks around pulley, a steel rope corresponding holding device all separately of pulley both sides, when needs brake sheave, two holding devices start together with brake equipment, directly make the relative position between pulley and steel rope be fixed, and by two gripping means grips steel ropes, ensure that its fixing stability.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Brake equipment is set, when being had swing by a relatively large margin by hoisting object, start brake equipment and pulley is braked, effectively prevent and rocked by waving of hoisting object, improve the safety in hoisting process, reduce contraposition difficulty, improve lifting efficiency.
