Abstract
The invention discloses a wire rope anti-bouncing device. The device comprises: a pulley shaft, a first support and a second support arranged on the two ends of the pulley shaft, a bearing arranged between the two supports, a bearing seat arranged on the bearing, and a first pulley arranged on the bearing seat. The first pulley is provided with a rope groove used for arranging a wire rope. The wire rope is arranged in the rope groove. The upper parts of the first support and the second support are connected through a connection bar. Blocking grooves are provided on the two ends of the pulleys. The outer sides of the first support and the second support are provided with blocking plates blocked in the blocking grooves. A second pulley is arranged on the connection bar at the position above the first pulley. When in use, rolling friction is formed between the wire rope and the second pulley, such that the abrasion of the wire rope can be reduced, and the service life of the wire rope can be prolonged.
Description
Technical field
The present invention relates to the hoisting crane industry, relate in particular to a kind of steel rope anti-bouncing device.
Background technology
In the hoisting crane industry, all be the up-down of controlling suspender through steel rope generally, yet steel rope is beated in the process that the control suspender goes up and down easily; Therefore steel rope might break away from pulley, needs a kind of steel rope anti-bouncing device of design to prevent that steel rope from beating, and sees also Fig. 1; Steel rope anti-bouncing device of the prior art comprises: sheave shaft, first support that is installed on the sheave shaft two ends and second support, be installed on bearing between the two stands, be installed on the bearing seat on the bearing and be installed on the pulley on the bearing seat, said pulley is provided with the grooving that steel rope is installed, and said steel rope is installed in this grooving; Said first support is connected through pipe link with the top of second support, thereby forms an osed top framework, can prevent that steel rope from jumping out outside the framework; Yet; The defective of this kind steel rope anti-bouncing device is: in use, form cliding friction between said steel rope and the pipe link, the wearing and tearing of steel rope are comparatively serious; Therefore, often need more change steel rope.
Therefore, be necessary to provide a kind of steel rope anti-bouncing device that solves the problems of the technologies described above.
Summary of the invention
Technical matters to be solved by this invention is: a kind of steel rope anti-bouncing device that reduces steel rope abrasion is provided.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of steel rope anti-bouncing device; It comprises: sheave shaft, first support that is installed on the sheave shaft two ends and second support, be installed on bearing between the two stands, be installed on the bearing seat on the bearing and be installed on first pulley on the bearing seat; Said first pulley is provided with the grooving that steel rope is installed; Said steel rope is installed in this grooving, and said first support is connected through pipe link with the top of second support, and the two ends of said sheave shaft are provided with draw-in groove; The outside of said first, second support is provided with the baffle plate that is snapped in this draw-in groove, and said pipe link also is equipped with second pulley above first pulley.
The invention has the beneficial effects as follows: second pulley is installed above first pulley through said pipe link.In use, form friction of rolling between the said steel rope and second pulley, thereby can alleviate the wearing and tearing of steel rope, improve the service life of steel rope.
