Description

Technical Field

[0001] The utility model relates to the field of lifting, in particular to a device for preventing a winch wire rope from being separated from a drum. Background Art

[0002] Cranes, in the past, due to operational reasons, the wire rope on the drum group sometimes detached from the two sides of the drum, and was wound between the drum group and the drum tile seat, or the wire rope was wound between the drum group and the speed reduction mechanism. The wire rope on the existing crane drum group will not detach from the drum under normal operation. However, in the case of misoperation, illegal operation, unskilled operation, side pulling and other lifting objects, the wire rope will detach from the drum. If it is not discovered in time, it will cause the wire rope to break; the speed reduction will be scrapped; or the drum tile seat will be scrapped. Accidents will occur. Not only will it affect the smooth progress of production, but it will also damage the equipment, thereby increasing equipment costs, reducing the economic benefits of the enterprise, and having a great impact on the entire production. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a device to prevent the steel wire rope of a hoisting machine from being separated from a drum, so as to solve the problem that the steel wire rope hoisted by a crane is separated from both sides of the drum.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for preventing a winch wire rope from detaching from a drum, wherein a rope passage opening is arranged on a frame below the drum, and limiting rollers are respectively arranged on both sides of the rope passage opening, the axes of the limiting rollers are perpendicular to the axis of the drum, and the limiting rollers are connected to the frame through a supporting seat.

[0006] The limiting roller comprises a round tube, a roller shaft is sleeved in the round tube, two ends of the roller shaft are connected to the round tube through bearings, and the two ends of the roller shaft are connected to the support seat.

[0007] The outer edge of the limiting roller is less than 30 mm away from the edge of the reel.

[0008] The diameter of the limiting roller is 60-100 mm.

[0009] The support seat is connected with the frame by bolts.

[0010] The frame is provided with a long hole connected to the supporting seat.

[0011] The elongated hole is parallel to the axis of the reel.

[0012] Compared with the existing technology, the beneficial effects of the utility model are:

[0013] The utility model limits the position of the wire rope, and the wire rope will not fall between the drum and the speed reduction mechanism or between the drum and the tile seat, thereby playing a protective role. The wire rope is prevented from being separated from both sides of the drum, thereby avoiding the occurrence of accidents. BRIEF DESCRIPTION OF THE DRAWINGS
