Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Example (b): as shown in fig. 1-3, a tensioning device, installed at a bend section of a belt conveyor, includes a mounting frame 1, a tensioning roller 2 having a mounting shaft 201 and installed on the mounting frame 1, a pair of adjusting mechanisms 4 for adjusting the position of the tensioning roller 2 on the mounting frame 1, and a guiding mechanism 5 for guiding when the position of the tensioning roller 2 is adjusted.

The applicant finds that when the existing long belt is adjusted, the tensioning devices are required to be installed on the plurality of driving devices to tension the belt, the tensioning degrees cannot be unified generally in actual operation, the working efficiency is low, the adjustment degrees at multiple positions are different, so that stress at multiple positions on the belt is uneven, the damage to the belt is accelerated, and the production efficiency is reduced when the belt is replaced subsequently. The belt tensioning work is carried out through setting up overspeed device tensioner on a drive arrangement to the realization, promotes tensioning work efficiency, eliminates the tensioning degree of regulation and differs to bring the damage to the belt, promotes production efficiency.

In the present embodiment, the guide mechanism 5 includes an upper guide plane 501 and a lower guide plane 502 provided at the end of the mounting shaft 201, and a guide long groove 503 provided in the mounting frame 1. The upper guide plane 501, the lower guide plane 502 and the guide long groove 503 are in a pairwise parallel relationship, so that the accuracy of guiding the tensioning roller 2 by the guide long groove 503 is maintained.

In this embodiment, a limit connecting end 6 is provided at an end of the mounting shaft 201, and the limit connecting end 6 includes an upper limit surface 61 and a lower limit surface 62 which are in contact with the guide long groove 503. The upper limit surface 61 and the lower limit surface 62 respectively contact the guide slot 503, so that the stability of the connection between the mounting shaft 201 and the guide slot 503 is ensured.

In the present embodiment, the length of the guide mechanism 5 is longer than the length of the upper limit surface 61 or the lower limit surface 62. The mounting shaft 201 is ensured to move in the guiding long groove 503, so that the adjusting function is provided, and the mounting shaft can be used for redirection sections with different specifications.

In this embodiment, the adjusting mechanism 4 includes a tensioning bolt 41, the tensioning bolt 41 penetrates through the limit connection end 6, and adjusting compression nuts 42 are respectively disposed at an inlet and an outlet of the tensioning bolt 41 and the limit connection end 6.

Further, the installation frame 1 is equipped with the installation riser 11 at tensioning bolt 41 both ends, tensioning bolt 41 through the mounting nut with the installation riser 11 is connected.

In the present embodiment, the distance between the two mounting risers 11 is longer than the length of the guide mechanism 5.

In the present embodiment, the upper guide plane 501 and the lower guide plane 502 are provided with mounting holes 12 at intervals.
