Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a corrugated sidewall belt conveyor and a lower idler device thereof. Background Art

[0002] The conveying angle of the corrugated sidewall belt conveyor can reach up to 90°, which is an ideal device for large-angle conveying and vertical conveying. It saves floor space, equipment investment and civil engineering costs, and the corrugated sidewall belt conveyor is widely used in various fields. The corrugated sidewall belt 6 of the corrugated sidewall belt conveyor is composed of a base belt, corrugated sidewalls 62 and partitions 63.

[0003] The lower idlers of the corrugated sidewall belt conveyor in the prior art are divided into two types: single idlers and double idlers. As shown in Figure 1 When the belt width B of the corrugated sidewall belt 6 is ≤ 800 mm, single idlers are used. A lifting frame one 31 and a lifting frame two 32 are installed on the frame. The lifting frame one 31 and the lifting frame two 32 are arranged oppositely, and the main idler 1 is installed on both the lifting frame one 31 and the lifting frame two 32 at the same time. The main idler 1 supports the corrugated sidewalls 62 and the partitions 63.

[0004] As shown in Figure 2 and Figure 3 jointly, when the belt width B of the corrugated sidewall belt 6 is ≥ 800 mm, double idlers are used. In addition to the main idler 1 installed on the lifting frame one 31 and the lifting frame two 32, an auxiliary idler one 21 and an auxiliary idler two 22 are also included. The auxiliary idler one 21 is connected to the lifting frame one 31 through a connecting piece one, and the auxiliary idler two 22 is connected to the lifting frame two 32 through a connecting piece two. The auxiliary idler one 21 supports the first side 611 of the base belt of the base belt, and the auxiliary idler two 22 supports the second side 612 of the base belt of the base belt.

[0005] Whether it is a single idler or a double idler, it will cause wear to the corrugated sidewalls 62 and the partitions 63 of the corrugated sidewall belt 6, affecting the service life of the corrugated sidewall belt 6. The main idler 1 is arranged below the corrugated sidewall 6, and there will be a situation where the main idler 1 is too close to the ground, and coal lumps and coal ash cannot be cleaned, and even the coal lumps may affect the normal operation of the idler.

[0006] In addition, a lower deviation correcting idler one 41 and a lower deviation correcting idler two 42 are also arranged on the intermediate frame fixedly connected to the frame. The lower deviation correcting idler one 41 and the lower deviation correcting idler two 42 are both arranged downward. Due to the increase in the diameters of the head and tail drums, the torques of the lower deviation correcting idler one 41 and the lower deviation correcting idler two 42 are too large, resulting in deformation of the idler shafts of the lower deviation correcting idler one 41 and the lower deviation correcting idler two 42, thus affecting the normal operation of the lower deviation correcting idler one 41 and the lower deviation correcting idler two 42, and there may also be a situation where the transition section cannot block the corrugated sidewall belt 6.
