Embodiment 1

[0011] Such as figure 1 , the middle idler 2 and the side idler 3 are installed on the crossbeam 1, and are fixedly installed by respective idler brackets and ribs. Among them, the angle between the side idler and the beam is α, which is 65°, and the angle between the middle idler and the beam is β, which is 20°. Such as figure 2 , The distance L between the front and back of the middle idler and the side idler is 1.2 times the diameter of the idler.

Embodiment 2

[0013] Such as figure 1 , the middle idler 2 and the side idler 3 are installed on the crossbeam 1, and are fixedly installed by respective idler brackets and ribs. Among them, the angle between the side idler and the beam is α, which is 65°, and the angle between the middle idler and the beam is β, which is 25°. Such as figure 2 , The distance L between the front and back of the middle idler and the side idler is 1.5 times the diameter of the idler.

Embodiment 3

[0015] Such as figure 1 , the middle idler 2 and the side idler 3 are installed on the crossbeam 1, and are fixedly installed by respective idler brackets and ribs. Among them, the angle between the side idler and the beam is α, which is 65°, and the angle between the middle idler and the beam is β, which is 30°. Such as figure 2 , The distance L between the front and back of the middle idler and the side idler is 1.8 times the diameter of the idler.

Abstract

The invention relates to a carrier roller set, in particular to a deep groove carrier roller set. The deep groove carrier roller set solves the problems that the freight volume is reduced and a belt is bent and abraded easily due to the fact that a carrier roller set in the prior art is small in groove angle. The deep groove carrier roller set is large in groove angle, comprises a middle carrier roller and side carrier rollers installed on a cross beam, and is characterized in that the included angle between each side carrier roller and the cross beam is 65 degrees, and the included angle between the middle carrier roller and the cross beam is 20-30 degrees. According to the deep groove carrier roller set, the groove depth is further increased by increasing the groove angle of the side carrier rollers to 65 degrees, the clamping force and the frictional force of a conveying belt on materials are increased so that the conveying belt can operate safely and stably in a roadway with a large gradient, and meanwhile the freight volume is guaranteed. In the operating process, the middle carrier roller and the side carrier rollers can be arranged front and back, and the belt can be effectively prevented from being bent and damaged.

Description

technical field [0001] The invention relates to an idler roller set, in particular to a deep groove idler roller set. Background technique [0002] The deep groove roller set is widely used on the belt conveyor under the mine. Because of its large clamping force and large inclination angle on the material, it is suitable for the material transportation of the mine roadway. Currently commonly used deep groove idlers, side rollers have an inclination angle of 35°, 45° or 55°. These idler sets cannot guarantee normal transport volume when the inclination angle of the roadway is large, which affects production efficiency. If the intermediate rollers and side rollers are arranged in a straight line, it will cause a large bend to the belt, which will aggravate its damage. Contents of the invention [0003] Aiming at the problems in the prior art that the transportation volume is reduced due to the small groove angle and the belt is easy to bend and wear, the invention provides ...
