Abstract
The utility model relates to a rope sleeve type rotation preventing device used for preventing the steel cable of a hoister and goods from rotating. The rope sleeve type rotation preventing device is characterized in that a rope sleeve whose inner hole is trumpet-shaped is connected with a rotating shaft. The end hole opening of the rope sleeve is provided with a screw thread whose tail end is provided with a ditch trough and a leak hole. The trumpet-shaped surface of the inner hole is provided with convex ribs or concave troughs or netted irregularities, which is convenient to be fused with the tin base alloy with a low melting point at the tail end of the steel cable of the hoister. The joint strength is improved. The utility model is directly connected with the steel cable, the utility model does not need to be provided with an intermediate junction piece, the extra abrasion caused by the intermediate junction piece can be avoided, the junction length is shortened, and the effective lifting height of the hoister is enhanced.
Description
The utility model relates to a kind of rope sling type anti-rotation device that prevents crane rope and goods rotation, and belong to and be used for hoisting crane, capstan engine, the load of winch or coaster tangles part or device.
In known technology, prevent that the anti-rotation device of crane rope and goods rotation from being by anti-pivoted housing, hold-doun nut, bearing, hollow plug screw and anti-rotating shaft are formed.Its purpose is to place the end of hoist rope, the top of goods, overcomes the unrelieved stress of steel rope in the twisting process, steel rope and goods rotation when preventing that steel rope is stressed.Its weak point is that cable wire end must be made eye splice or with aluminum alloy sleeve compacting, and then connects with unloading gram or coupling link, and hook spare is many like this, has increased extra unnecessary wearing and tearing, and connection length is big, has lost effective hoisting depth of hoisting crane.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of and various model steel ropes and anti-rotation device direct connection can be in the same place, and reduces attaching parts, improves the rope sling type anti-rotation device of the effective hoisting depth of hoisting crane.
The purpose of this utility model can reach by following measure:
Endoporus is the poroid rope sling of loudspeaker, and its stomidium mouth has screw thread to be connected with rotating shaft, and bearing is passed through in rotating shaft, hold-doun nut, and hollow plug screw and anti-rotation cover fuse.
The stomidium mouth screw thread tail end of rope sling has groove, and aperture is arranged on the groove.
The inside trumpet face of rope sling is netted uneven.
The profile of rope sling top ends is square or hexagon.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the rope sling type anti-rotation device that the utility model proposes.
Fig. 2 is crane rope and the rope sling that the utility model proposes and the connection diagram of steel rope.
Fig. 3 is the section-drawing that the inside trumpet face of the rope sling that the utility model proposes has convex tendon (a) or groove (b).
Fig. 4 is that the rope sling inside trumpet face that the utility model proposes is netted section-drawing.
Describe in detail according to the concrete device that the utility model proposes below in conjunction with legend:
Earlier clean is carried out in the inside trumpet hole (7) of rope sling (6) during installation, the inside trumpet hole (7) of crane rope (12) end being passed rope sling (6) is the chrysanthemum shape in the non-preformed wire rope end again, the tin alloy (13) of ladling out the dedust slag after will melting then slowly injects in the chamber, inside trumpet hole (7), until filling up groove (9), unnecessary tin alloy solution flows out from the leak (10) on the groove (9).
There are convex tendon (11) or groove (12) in the surface in the inside trumpet hole (7) of Fig. 3 and rope sling (6) shown in Figure 4 or are netted uneven surface (13) all is in order to increase the affixed area of steel rope (14) end low melting point tin antimony alloy (15) and rope sling (6), improve its Joint strenght, prevent loosening sliding phenomenon.
One end of rotating shaft (15) installs hollow plug screw (14) earlier, bearing (2) and hold-doun nut (2) again with hollow plug screw (4) and anti-pivoted housing (1) by being threaded togather.
Rope sling (6) outer end portion (16) is square or hexagon, and available in view of the above wrench links into an integrated entity rope sling (6) and rotating shaft (5) by screw thread (8).
The utility model is compared with original technology has following advantage: crane rope directly and anti-rotation device join, the additional wear of having saved intermediate connector and having caused, and greatly reduced connecting length has improved effective hoisting depth of crane.
Claims (5)
1, a kind of rope sling type anti-rotation device that prevents crane rope and goods rotation, has anti-pivoted housing (1), hold-doun nut (2), bearing (3), hollow plug screw (4), rotating shaft (5) is characterized in that: endoporus is the rope sling (6) of horn-like (7), and its stomidium mouth has screw thread (8) to be connected with rotating shaft (5).
2, rope sling type anti-rotation device according to claim 1 is characterized in that the tail end of described rope sling (6) stomidium mouth screw thread (8) has groove (9), and leak (10) is arranged on the groove.
3, rope sling type anti-rotation device according to claim 1 and 2, the endoporus that it is characterized in that described rope sling (6) are on the surface of horn-like (7) some convex tendons (11) or groove (12)
4, rope sling type anti-rotation device according to claim 1 and 2, the surface that the endoporus that it is characterized in that described rope sling (6) is horn-like (7) is netted uneven (13).
5, rope sling type anti-rotation device according to claim 1 and 2 is characterized in that the outer end portion (16) of described rope sling (6) is square or hexagon.
