[0023] The utility model provides a device for replacing rollers of a mining belt conveyor.
[0024] Example 1:
[0025] like Figures 1-4 As shown, it includes a positioning frame 1, which is U-shaped and inverted, so that it can be easily put on the longitudinal beam surface of the belt conveyor bracket. One side and the top of the positioning frame 1 are fixedly connected with an inclined sleeve 11, and the two sleeves 11 are internally slidably connected with support rods 2. The ends of the two support rods 2 are fixedly connected with a U-shaped frame 21, and the interior of the U-shaped frame 21 is rotatably connected with a support roller 22. One side of the positioning frame 1 is fixedly connected with a first screw 12, and the outer surface of the first screw 12 is threadedly connected with a threaded barrel 3. One side of the U-shaped frame 21 is fixedly connected with a second screw 24, and the second screw 24 is threadedly connected Inside the threaded barrel 3, by rotating the threaded barrel 3, the first screw 12 and the second screw 24 are extended from the threaded barrel 3 at the same time, and the distance between the support roller 22 and the positioning frame 1 can be adjusted, and the outer surface of the threaded barrel 3 is fixedly connected with a handle 31, which is convenient for rotating the threaded barrel 3. The outer surface of the U-shaped frame 21 is slidably connected with a baffle 4, and both sides of the U-shaped frame 21 are fixedly connected with a slide 23. A notch 41 is opened on one side of the baffle 4, and the baffle 4 is slidably connected to the slide 23 through the notch 41.
