Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5, the utility model provides a technical solution: the utility model provides a novel belt conveyor overspeed device tensioner, including frame 1, 120 type worm wheel reel 2 is installed to one side of frame 1, frame 1's front and back all are provided with track 3, the position department of keeping away from 120 type worm wheel reel 2 in track 3's top installs bend pulley 4, track 3's inside is provided with slider 5, slider 5 rotates with tensioning pulley 6's tip to be connected, one side that slider 5 is close to 120 type worm wheel reel 2 is provided with eyebolt 7, be provided with wire rope 8 between eyebolt 7 and the 120 type worm wheel reel 2, bend pulley 4 and tensioning pulley 6's surface winding has belt 9.

As a technical optimization scheme of the utility model, the position department that belt 9 corresponds bend drum 4 and tensioning roller 6 is the S-shaped, and the stroke that increases belt 9 makes belt 9' S the whole direction of delivery unchangeable, can reach the effect of tensioning simultaneously, and the tensioning stroke is big, improves the suitability.
