[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] As shown in the figure, the utility model discloses a tool for replacing belt rollers, including a push rod 1 and a supporting slot 2, two parallel supporting ear plates 3 are installed at the lower end of the push rod 1, a supporting ear plate 2 is provided between the two parallel supporting ear plates 1 3, the supporting ear plate 1 3 is connected to the supporting ear plate 2 by a pin shaft 4, the supporting ear plate 2 is installed on the top of a threaded shaft 5, the supporting slot 2 is installed at the bottom of another threaded shaft 5, the two threaded shafts 5 are threadedly connected to the shaft sleeve 6, and two symmetrical handles 7 are welded on the shaft sleeve 6.

[0024] When in use, the utility model and the new belt roller are transported to the belt line position where the roller needs to be replaced, the top rod 1 is located below the belt 10, the supporting slot 2 is placed on the channel steel bracket 9 of the belt conveyor, and the shaft sleeve 6 is driven to rotate by rotating the handle 7, so that the distance between the two threaded shafts 5 is increased, and finally the length between the top rod 1 and the lower slot 2 is increased, so as to increase the gap between the belt 10 and the roller 11 until the belt 10 and the roller 11 are out of contact, and the old roller is taken out and replaced with a new roller;

[0025] Then rotate the handle 7 in the opposite direction to make the top rod 1 drop, and there is no force between the top rod 1 and the belt 10, then take out the utility model, and the roller replacement operation is completed;

[0026] The utility model is used to carry out roller changing operation, which is very convenient and quick and is worthy of popularization and use.
