Auxiliary rope arrangement side wall baffle structure of multi-layer winding drum

Abstract

The invention relates to a multi-layer winding drum auxiliary rope arrangement side wall baffle structure which comprises a drum side plate, a drum double-fold line rope groove and side wall baffles, and the side wall baffles are installed at steel wire rope secondary climbing sections on the two sides of the drum side plate and used in cooperation with the drum double-fold line rope groove. The triangular area of the climbing position of the two layers of steel wire ropes of the double-broken-line type winding drum is effectively filled, so that the arrangement gaps of the steel wire ropes in each layer are reduced, and the steel wire ropes are effectively prevented from being embedded due to no supporting layers; when the steel wire ropes are not tightly arranged on the middle layer and the outer layer of the winding drum, rope arrangement can be assisted at the layer changing position, and the steel wire ropes are helped to be wound to correct positions; the side wall baffles can prevent the steel wire ropes from changing layers in advance during layer changing, the steel wire ropes are regularly arranged from the bottom layer, and therefore the steel wire ropes of the whole reel are arranged in order.

Description

Technical Field

[0001] The invention relates to a multi-layer winding drum, in particular to a multi-layer winding drum auxiliary rope arrangement side wall baffle structure. Background Art

[0002] The drum is one of the important parts of the winch. The neat arrangement of wire ropes on the drum is the basis for ensuring the normal operation of the winch. For multi-layer wound drums, rope arrangement is one of the key issues that need to be addressed. Commonly used auxiliary rope arrangement measures include using double-fold rope grooves, adding rope arrangement devices to the winch to assist in rope arrangement, etc. During the process of changing the middle and outer layers of the drum using double-fold rope grooves, due to the gap between the wire rope and the drum side baffle, in some cases the wire rope will fall into the gap, resulting in uneven arrangement of the wire rope at the layer change location, which will cause the middle and outer layers of the wire rope to be tangled. In response to the above problems, it is necessary to develop a drum side plate baffle to assist in arranging the wire rope at the drum layer change location to achieve neat arrangement of the wire rope. Summary of the invention

[0003] The present invention provides a multi-layer winding drum auxiliary rope arrangement side wall baffle structure, which is mainly used for multi-layer winding winch drums, and cooperates with double-fold drum rope grooves to assist the arrangement of wire ropes to the correct position at the middle layer or outer wire rope layer change point.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a multi-layer winding drum auxiliary rope arrangement side wall baffle structure, including a drum side plate, a drum double-fold rope groove, a side wall baffle, and a side wall baffle installed at the secondary climbing section of the wire rope on both sides of the drum side plate, and the side wall baffle is used in conjunction with the drum double-fold rope groove.

[0005] Furthermore, the height of the side wall baffle covers the steel wire ropes from the third layer to the outermost layer of the drum to ensure that each layer of the steel wire ropes is arranged neatly.

[0006] Furthermore, the side wall baffles are symmetrically arranged on the side plates of the drum and are welded to the side plates of the drum in a circle by using fillet welds.

[0007] Furthermore, the maximum thickness H of the side wall baffle is determined by the maximum value of the gap at the intersection when the two layers of wire ropes are replaced, and is adjusted according to the actual gap between the wire rope and the side wall.

[0008] Furthermore, the edge radius r of the side wall baffle is made into an excessive radius according to the size of the side wall baffle.

[0009] Furthermore, the outer diameter Ra of the side wall baffle is 1 to 1.5 times the rope diameter larger than the outermost circle wire rope winding diameter; the inner diameter Rb of the side wall baffle is 0.5 times the rope diameter larger than the third layer winding diameter; the width B of the side wall baffle is the straight length of the single-sided climbing section angle of the double-fold rope groove at the innermost layer of wire rope.

[0010] The beneficial effects brought by the technical solution of the present invention are as follows:

[0011] 1. Effective filling is done in the triangular area where the two layers of wire ropes on the double-fold drum climb, so that the gap between each layer of wire ropes is reduced, effectively preventing the wire ropes from being embedded in the layer due to lack of support;

[0012] 2. When the wire rope is not arranged tightly in the middle and outer layers on the drum, auxiliary rope arrangement can be used at the layer change point to help the wire rope be wound to the correct position;

[0013] 3. The side wall baffle can prevent the wire rope from changing layers prematurely, ensuring the regular arrangement of the wire rope starting from the bottom layer, so that the wire rope of the entire drum is arranged neatly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 5 As shown, an embodiment of the present invention provides a multi-layer winding drum auxiliary rope arrangement side wall baffle structure, including a drum side plate 1, a drum double-fold rope groove 2, and a side wall baffle 3. The side wall baffle 3 is installed at the secondary climbing section G of the wire rope on both sides of the drum side plate 1, and the side wall baffle 3 is used in conjunction with the drum double-fold rope groove 2.

[0022] The height of the side wall baffle 3 covers the steel wire ropes from the third layer to the outermost layer of the drum to ensure that each layer of the steel wire ropes is arranged neatly.

[0023] The side wall baffles 3 are symmetrically arranged on the side wall of the drum and are welded to the side wall of the drum in a circle by fillet welds.

[0024] The external dimensions of the side wall baffle 3 are shown in the figure below: Figure 4 , as shown in 5, the maximum thickness H of the side wall baffle 3 is Figure 1 When the two layers of wire rope are replaced, the maximum value of the gap at the intersection in the top view is determined, and it can be adjusted according to the actual gap between the wire rope and the side wall; the edge fillet r is made into a transition fillet according to the size of the side wall baffle; the outer circle diameter Ra is 1 to 1.5 times the rope diameter larger than the outermost circle wire rope winding diameter; the inner circle diameter Rb is 0.5 times the rope diameter larger than the third layer winding diameter; the width B is the straight length of the angle of the single-side climbing section of the double-fold rope groove at the innermost layer of wire rope.

[0025] Key technical points of the present invention:

[0026] 1. The side wall baffle must be used in conjunction with the double-fold rope groove. To ensure that the side wall baffle plays the maximum role, the external dimensions should be determined according to the parameters of the double-fold rope groove of the drum;
