Fig. 1 is a schematic view of a belt conveyor idler replacement tool of the present utility model.

In the figure, 1, a supporting frame; 2. an upper roller frame; 3. an upper carrier roller; 4. a hoist; 5. a flexible hoisting structure; 51. a hook; 61. a jackscrew; 62. a sleeve; 63. a fixed pulley assembly; 7. a lower carrier roller; 8. a belt rack; 9. a belt.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and the following embodiments are used to illustrate the present utility model.

As shown in fig. 1, the utility model discloses a carrier roller replacing tool for a belt conveyor, and the following carrier roller replacing example is used for describing the embodiment: the tool comprises a horizontally arranged support frame 1, wherein both ends of the support frame 1 are respectively erected at the lap joint of an upper carrier roller frame 2 and an upper carrier roller, or are placed at the lap joint of an upper carrier roller 3 and a conveying belt (not shown in the figure).

The upper carrier roller frame 2 and the upper carrier roller 3 are arranged between; the movable guiding structure is sleeved on the supporting frame 1, and a winch 4 is also fixed on the supporting frame; a flexible hoisting structure 5 is arranged on the guide structure, one end of the hoisting structure is connected with the winch 4, and the other end of the hoisting structure penetrates through the guide structure and the belt frame 8 and is connected with the lower carrier roller 7; when the lifting device is used, the position of the guide structure is required to be adjusted to be positioned right above the lower carrier roller 7 and fixed, then one end of the lifting structure is bundled on the lower carrier roller 7, and then the winch 4 is rotated to separate the lower carrier roller 7 from the carrier roller frame. Since the belt 9 above the lower roller 7 is very heavy, this method is time-saving and labor-saving compared to the use of manual lifting of the lower roller.
