Detailed Description

The utility model is further described in detail below by means of the figures and examples. The features and advantages of the present utility model will become more apparent from the description. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model.

As shown in fig. 1-3, the embodiment of the utility model discloses a rope outlet cover structure for a gantry crane, which comprises a hanger rail 1 and a moving part 2 capable of moving along the hanger rail, wherein the moving part is provided with a rope threading hole 202-1 for a steel wire rope to pass through, two ends of the moving part are respectively provided with a telescopic protective cover 3, one end of the telescopic protective cover is fixedly connected with one end of the moving part, and the other end of the telescopic protective cover is fixedly connected with the tail end of the hanger rail. Specifically, the steel wire rope drives the moving part to move on the hanger rail, and the telescopic protective covers on two sides of the steel wire rope correspondingly stretch, so that the length of a working space required by the whole protective cover is kept unchanged and is only slightly larger than the length of a rope outlet at the top of a machine room. The telescopic protective cover is made of metal plates, the top surfaces of the left side and the right side of the movement direction of the protective cover body are provided with downward inclined angles, rainwater can be split to the two sides, the rainwater cannot be gathered on the protective cover, and the risk of water leakage of a machine room can be reduced.

Preferably, the telescopic protection cover 3 comprises a plurality of protection cover segments 301 which are sleeved in sequence, the size of each protection cover segment 301 is gradually reduced from the moving mechanism to the tail end direction of the hanging rail, so that the whole telescopic protection cover has an inclined downward angle from the moving part to the tail end direction of the hanging rail, rain water flows to the tail end of the hanging rail, and the risk of water leakage of a rope outlet at the top of a machine room is reduced.

Preferably, the moving part comprises a moving frame 201, a hanging wheel 203 for moving on a hanging rail is arranged at the bottom of the moving frame, and a rain shield 202 provided with a rope penetrating hole 202-1 is further arranged, and the rain shield 202 is movably arranged in the moving frame.
