Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine winch equipment, in particular to a ground roller and a guiding device for a mine winch wire rope. Background Art
[0002] When the wire rope for mine winch is used to drag the equipment, a ground roller device is usually installed between the sleepers on both sides to allow the wire rope to pass through the ground roller, thereby preventing the wire rope from cutting the sleepers. Common ground roller devices include ground rollers and I-beam support frames located at both ends of the ground rollers for supporting the ground rollers. Since the wire rope will exert great pressure on the ground rollers when dragging the equipment, the huge cutting force generated will continuously cut the metal ground rollers, causing the ground rollers to be damaged and the entire ground roller needs to be replaced; especially in places where the slope changes, due to the concentrated force, the service life of the ground rollers will become shorter and the replacement frequency will increase. However, when the ground roller is damaged, not all positions will be severely worn. Usually only some positions are heavily worn. At this time, it is a waste to replace the ground rollers as a whole. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as the prior art known or should be known to those skilled in the art, such as the specific structure, model and working principle of the winch 1, how the wire rope 102 is wound around the winch 1, etc.
[0021] Example 1
[0022] A ground roller for a mine winch wire rope, such as Figure 1 and Figure 3 As shown, it includes a support shaft 3 and multiple bearing sleeves 5, and the bearing sleeves 5 can be set to three. A rotating drum 4 is rotatably sleeved on the support shaft 3, and a dovetail groove 401 is opened on the outer wall of the rotating drum 4 along its axial direction. A retaining ring 301 is fixedly sleeved on one end of the support shaft 3, and a limiting assembly is detachably provided on the other end. The inner walls of all the bearing sleeves 5 are fixedly connected with guide bars 501 along their axial direction, and the guide bars 501 cooperate with the dovetail groove 401. The guide bars 501 can be set as dovetail bars. The dovetail groove 401 specifically has an opening spacing that is smaller than the width of the bottom wall of the dovetail groove 401, which can prevent the bearing sleeve 5 from falling off radially from the rotating drum 4 during rotation. After the guide bar 501 of the bearing sleeve 5 slides into the dovetail groove 401, the inner wall of the bearing sleeve 5 fits with the outer wall of the rotating drum 4, and the retaining ring 301 and the limiting assembly can prevent the guide bar 501 from falling out of the dovetail groove 401. Once the surface of one of the bearing sleeves 5 is severely worn after long-term use, the limiting assembly can be directly removed, and then the damaged bearing sleeve 5 is slid out of the dovetail groove 401, and then a new bearing sleeve 5 is installed, and finally the limiting assembly is installed.
