Description

Wire rope shock absorber

technical field

The utility model relates to a steel wire rope damping device, in particular to a steel wire rope damping device in the field of hoisting equipment.

Background technique

At present, in industrial production, the use of lifting equipment can be seen everywhere, such as grab cranes, hoist cranes, bridge cranes, etc. These equipment are lifted by wire ropes, so the use of wire ropes is very important for the use of cranes. How to protect the wire rope has become the top priority for the safe use of cranes. When the lifting equipment is working, the steel wire rope passes through the drum and a series of pulleys continuously, and is subjected to bending force and extrusion force repeatedly, so that the wire rope will be fatigued and broken. Especially on the grab lifting equipment, due to the large size of the grab, there will be a swing phenomenon under the action of the wind, which will cause the steel wire rope to shake accordingly. The rigid friction of the steel plate on the surface of the bucket is intensified, which reduces the service life of the steel wire rope. For this reason, a kind of anti-shock device for steel wire rope appears on the market, and the anti-shock device is fixed on the grab bucket. After the steel wire rope passes through the anti-shock device, it can effectively reduce the shaking when the steel wire rope enters the inside of the grab bucket, thereby reducing the friction between the steel wire rope and the steel plate on the surface of the grab bucket. , effectively protecting the wire rope. But although the limit piece of this shock absorbing device can effectively prevent the front and rear rocking of the steel wire rope, due to the irregularity of the steel wire rope shaking, it often jumps out of the protection range of the limit piece and rubs against the limit plate. It is symmetrically set, and its friction point is located at the butt joint of the limit plate. Because there is a gap at this friction point, the strength is low, and grooves are prone to appear after friction with the wire rope, and the wire rope is clamped, so that the wire rope cannot work normally. , easy to damage the wire rope.

Further, both sides of the support plate are also provided with triangular reinforcing ribs perpendicular to the support plate.

The beneficial effects of the utility model are: the wire rope damping device of the present application passes the wire rope through the rectangular frame surrounded by the front baffle, the rear baffle, the left wing and the right wing, and the wire rope is , Tailgate, left wing and right wing, the range of vibration is limited to the rectangular frame, thereby reducing the friction between the wire rope and the steel plate on the surface of the grab bucket, effectively protecting the wire rope. In addition, due to the limit pieces on the front and rear baffles, the swing of the steel wire rope in the rectangular frame is also restricted by the limit pieces. Due to the blocking of the limit pieces, the chances of collision and friction between the steel wire rope and the left and right wing plates during the swing process are greatly increased. Therefore, the steel wire rope damping device of the present application can effectively prevent the friction between the steel wire rope and the spreader when it enters the spreader, and at the same time prevent the steel wire rope from rubbing against the limit plate in the shock absorber to produce grooves to clamp the steel wire rope, so that the steel wire rope cannot Under normal working conditions, the service life of the wire rope is improved, the maintenance cost is reduced, and the work efficiency is improved.

The wire rope damping device of the present application passes the wire rope from the rectangular frame surrounded by the front fender 1, the rear fender 2, the left wing 3 and the right fender 4. The plate 2, the left wing plate 3 and the right wing plate 4 are restricted, and the vibration range is restricted within the rectangular frame, thereby reducing the friction between the steel wire rope and the steel plate on the surface of the grab bucket, and effectively protecting the steel wire rope. In addition, since the front and rear baffles 2 are provided with limit pieces, the swing of the steel wire rope in the rectangular frame is also constrained by the limit pieces. Due to the blocking of the limit pieces, the steel rope collides and rubs against the left and right wing plates 4 during the swing process. The chance is greatly reduced, so the steel wire rope damping device of the present application can effectively prevent the friction between the steel wire rope and the spreader when it enters the spreader, and at the same time prevent the steel wire rope from rubbing against the limit plate in the shock absorber to produce grooves to clamp the steel wire rope.
