The technical scheme of the utility model is as follows:
a shaft coupling and transmission shaft protective cover for a crane comprises a protective cover body, wherein two ends of the top of the protective cover body are respectively provided with a slideway hole, and a dustproof cover is movably arranged on the slideway hole; the side of protection casing body below sets up support piece mounting hole, installs support piece on the protection casing body through the bolt, and support piece fixed mounting is on the hoist.
The dustproof cover is of a bent groove-shaped structure, two round holes are formed in the upper surface of the dustproof cover and used for mounting the flat-head rivet nut, and the flat-head rivet nut is matched with the butterfly screw to mount the dustproof cover on the protective cover body.
Both ends and the middle of the side surface of the protective cover body are provided with mounting holes for supporting pieces.
The supporting piece is a strip U-shaped structure formed by bending a thin plate, and a vertical row of bolt holes with equal intervals are arranged on the surface of the supporting piece.
The lower end part of the supporting piece is connected to the rectangular pipe through a fastening screw, and the lower surface of the rectangular pipe is welded and fixed on the crane.
Compared with the prior art, the utility model has the following technical effects: firstly, the observation window grid holes are additionally arranged on the protective cover, so that the use conditions of the coupler, such as the rotating operation condition of the coupler, the bolt connection condition and the like, can be conveniently checked at regular intervals, and the personnel injury caused by the flying of rotating materials can be prevented; secondly, increase the shield, can realize covering and opening the observation pane through the push-and-pull, also can prevent that the grease that the shaft coupling "got rid of oil" caused from splashing when the mechanism moves. Thirdly, the function of installing and supporting the middle of the protective cover is added, the protective cover is provided with mounting holes of the supporting piece at two end parts, and the mounting hole of the supporting piece is also arranged in the middle of the protective cover, so that when the end part of the protective cover cannot be installed and supported when the space is limited, the protective cover can be installed and supported in the middle of the protective cover; fourthly: the disassembly and assembly are convenient to adjust, and the installation, disassembly and height adjustment of the supporting legs of the protective cover can be realized by adjusting the fastening screws.

Detailed Description
The present invention is not limited by the following examples, and specific embodiments may be determined according to the technical solutions and practical situations of the present invention.
As shown in fig. 1, 2 and 3, a shaft coupling and transmission shaft protective cover for a crane comprises a protective cover body 2, wherein the protective cover body 2 is used for protecting the shaft coupling and a floating shaft from being damaged by external force and preventing rotating materials from flying out to hurt people. The upper surfaces of the two end parts of the protective cover body 2 are provided with observation panes 9 for observing the use condition of the coupler. The two ends of the top of the protective cover body 2 are respectively provided with a slideway hole, and the slideway hole is provided with a dustproof cover 1 through a flat-head rivet nut 4 and a butterfly screw 3 for installing and moving the dustproof cover 1. The dustproof cover is in a bent groove-shaped structure as shown in figure 2, two round holes are formed in the upper surface of the dustproof cover and used for installing flat-head rivet nuts 4, the flat-head rivet nuts 4 are matched with the butterfly screws 3 to install the dustproof cover 1 on the protective cover body 2, when the butterfly screws 3 are screwed down, the dustproof cover 1 can be fixed on the protective cover body 2, the butterfly screws 3 are loosened, and the protective cover body 2 is pushed and pulled along the slideway holes, so that the observation window panes 9 can be covered and opened. When the working condition of the coupler needs to be checked, the observation pane 9 is opened by the movable dustproof cover 1, the observation pane 9 is covered by the movable dustproof cover 1 after the checking is finished, and grease splashing caused by oil throwing of the coupler during the operation of the mechanism can be prevented.
