TECHNICAL FIELD

[0001] The utility model relates to a kind of multi-layer winding reel, especially a kind of multi-layer winding reel auxiliary rope arranging side wall baffle structure. BACKGROUND

[0002] Reel is one of important components of winch, and steel wire rope is arranged neatly on reel, which is the basis for ensuring normal operation of winch. For multi-layer winding reel, arranging rope is one of the key problems to be solved. Commonly used measures for assisting in arranging rope mainly include using double-fold line type rope groove and winch increasing rope arranging device to assist in arranging rope. For reel using double-fold line type rope groove, in the process of changing layer in middle layer and outer layer, gap exists between steel wire rope and reel side baffle, which may cause steel wire rope to sink into gap in some cases, resulting in uneven arrangement of steel wire rope at changing layer, and thus causing disorder of steel wire rope in middle layer and outer layer. In view of the above problems, it is necessary to develop a reel side baffle to assist in arranging steel wire rope at changing layer of reel, so as to realize neat arrangement of steel wire rope.

[0003] The utility model provides a kind of multi-layer winding reel auxiliary rope arranging side wall baffle structure, mainly applied to multi-layer winding winch reel, cooperates double-fold line reel rope groove, and assists in arranging steel wire rope to correct position at changing layer of middle layer or outer side steel wire rope.

[0004] To achieve the above object, the utility model adopts the technical scheme of a kind of multi-layer winding reel auxiliary rope arranging side wall baffle structure, including reel side plate, reel double-fold line rope groove, side wall baffle, side wall baffle is installed at the second time climbing section of steel wire rope at both sides of reel side plate, and side wall baffle cooperates with reel double-fold line type rope groove.

[0005] Further, the height of side wall baffle covers the 3rd layer to the outermost layer of steel wire rope of reel, to ensure that the arrangement of steel wire rope is neat in each layer.

[0006] Further, side wall baffle is arranged symmetrically on reel side plate, and is welded on reel side plate by using fillet weld.

[0007] Further, the maximum thickness H of side wall baffle is determined by the maximum gap at the intersection when two layers of steel wire rope change, and is adjusted according to the actual gap between steel wire rope and side wall.

[0008] Further, the edge fillet r of side wall baffle is made a fillet according to the size of side wall baffle.

[0009] Further, the outer diameter Ra of side wall baffle is 1 to 1.5 times the diameter of the outermost layer of steel wire rope; the inner diameter Rb of side wall baffle is 0.5 times the diameter of the 3rd layer of steel wire rope; and the width B of side wall baffle is the linear length of the innermost layer of steel wire rope at the climbing section angle of double-fold line rope groove on one side.

[0010] The beneficial effects brought by the technical scheme of the utility model are as follows:

[0011] 1. The triangular area at the two-layer steel wire rope climbing position of the double-fold line type winding drum is effectively filled, so that the gap of each layer of steel wire rope arrangement is reduced, and the steel wire rope is effectively prevented from being embedded without support;

[0012] 2. When the steel wire rope is not closely arranged in the middle layer and the outer layer on the winding drum, the auxiliary rope arrangement can assist the steel wire rope to be wound to the correct position at the layer changing position;

[0013] 3. The side wall baffle can prevent the steel wire rope from being changed to the next layer in advance, and ensure the steel wire rope arrangement to be regular from the bottom layer, so that the steel wire rope arrangement on the whole winding drum is neat. BRIEF DESCRIPTION OF DRAWINGS
