Problems solved by technology
The original TD75 vertical roller self-aligning idler can only be used in one-way running belt conveyor, while the DTII and DTII(A) curved disc friction self-aligning idler cannot be adjusted due to friction. Once the side roller does not rotate, it is easy to Grinding through the rollers, damaging the conveyor belt
For the fixed friction or tapered self-aligning idlers, when the belt is large, when the heavy load deviates and causes the upper beam to tilt forward and deform or rotate inflexibly, not only the deviation cannot be corrected, but also the wear of the tape will be aggravated, and the use of the tape will be shortened. life

Embodiment Construction
[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0017] see figure 1 , the track friction self-aligning upper idler group shown in the figure includes the middle frame 100 of the belt conveyor and the rotating self-aligning idler group 200 .
[0018] The rotating self-aligning idler group 200 includes a rotating idler frame 210 , which is in a V-shaped structure, and an idler group is installed on the rotating idler frame 210 . The roller set includes a middle roller 211 and two side rollers 212, 213, the middle roller 211 is installed in the middle of the rotating roller frame 210 through the left and right middle pillars 214, 215, and the two side rollers 212, 213 are symmetrically installed on On the rotating idler frame 210 and on both sides of the middle roller 211, the side roller 212 i...

The invention discloses an upper automatically-aligning idler group using track friction. The group comprises tape machine intermediate frames and a rotating aligning idler group, wherein the rotating aligning idler group comprises a rotating idler frame and an idler group arranged on the rotating idler frame; the rotating idler frame is arranged on each tape machine intermediate frame through a rotating mechanism; the idler group comprises a middle roller and two side rollers; the middle roller is arranged at the middle of the rotating idler frame; two side rollers are arranged on the rotating idler frame symmetrically and are arranged at the two sides of the middle roller; the tape machine intermediate frames are respectively provided with an arc-shaped friction track at the two sides of the idler group; the roll shaft end of the end, far away from the middle roller of the side roller is slidably provided with an axially sliding friction vertical roll. By adopting the upper automatically-aligning idler group disclosed by the invention, the defect that the side roller shaft of the fixed forerake aligning idler has short service life and large running resistance is overcome, therefore, in the design of the long-distance tape machine, the forerake additional resistance is not considered and the investment and the energy are saved.
Description
technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a set of track friction self-aligning upper rollers used in belt conveyors. Background technique [0002] During the operation of the belt conveyor, due to many reasons such as manufacturing, installation and loading, it is inevitable that the belt running center will deviate from the center line of the conveyor. This kind of deviation, in serious cases, will cause material to be scattered on both sides of the conveyor, force the machine to stop or even tear the tape, causing significant economic losses to the user. But so far, the most effective way is to use self-aligning idlers. They all use the axis of the idler on the deviation side to tilt forward at a certain angle, so that the idler will generate lateral pushing force on the deviation belt during operation. , Straighten the tape step by step. The original TD75 vertical roller self-aligning idler can only be used ...
