Problems solved by technology
Since the V-belt and the pulley are closely matched, it is necessary to hold the V-belt with your hands and pull it obliquely outward to disengage the V-belt. It is easy to squeeze your hands, which is dangerous and laborious.
At this time, if the pulley is turned while pulling outward, the pulley is very labor-saving, but due to the structure, it is impossible to make the pulley drive.

Embodiment Construction
[0010] The implementation of the present invention will be further described below with reference to the accompanying drawings.
[0011] Such as figure 1 As shown, the structure of the present invention is: it comprises a wrench body 2, and one end of the wrench 2 is provided with an inner hexagonal head 1 matched with the pulley fastening nut, and the other end of the wrench body 2 is provided with a moving rod 3.
[0012] Such as figure 2 As shown, when in use, first set the inner hexagonal head 1 of the sleeve wrench body 2 on the fastening nut of the pulley, turn the moving lever 3, and make the pulley rotate synchronously, and at the same time, turn the V-belt outward along the rotation direction of the pulley Pull, and the V-belt will easily fall off from the pulley.

The invention discloses a simple and easy tool for dismounting a triangular belt of a scraper conveyor as well as a using method thereof. The tool is in a structure of a sleeve wrench which is characterized in that an inner allen head matched with a fastening nut of a belt wheel is arranged at one end of a wrench body, and a moving rod is arranged at the other end of the wrench body. When the tool is in use, the allen head of the sleeve wrench body is sleeved on the fastening nut of the belt wheel, the moving rod is rotated, so that the belt wheel rotates synchronously; and meanwhile, the triangular belt is pulled outwards along a rotating direction of the belt wheel, so that the triangular belt is easily released from the belt wheel. Although the tool provided by the invention is simple, the big problem that the triangular belt is difficult to dismount can be solved, so that the maintenance time is saved; the labor intensity of staff is reduced; the workers are prevented from being hurt at work; and the humanization is realized.
Description
technical field [0001] The present invention relates to removal tools. Background technique [0002] At present, some scraper conveyors used in coal mines use V-belts to realize the transmission of the motor and the reduction box. After a long period of continuous operation, the V-belts will be seriously worn and should be replaced in time. Since the V-belt and the pulley are closely matched, it is necessary to grasp the V-belt and pull it outwards obliquely when replacing it, so that the V-belt can be disengaged. This is easy to squeeze your hands, which is dangerous and laborious. At this time, if the pulley is rotated outwards, the belt pulley is very labor-saving, but due to the structure, there is no way to start, and the belt pulley cannot be driven. Contents of the invention [0003] The purpose of the invention is to design a simple tool for dismounting the V-belt, and at the same time provide a method for dismounting it. [0004] In order to achieve the above pu...
