Description

Technical Field

[0001] The utility model relates to a belt conveyor bearing roller frame which is convenient for replacing rollers and belongs to the technical field of belt conveyor equipment. Background Art

[0002] Belt conveyor is a kind of equipment that uses a continuously running conveyor belt to transport materials efficiently. It is widely used in coal unloading ports. General belt conveyors are mainly composed of conveyor belts, drive mechanisms, redirecting rollers, load-bearing roller groups and return roller groups. The load-bearing roller group includes a roller frame and three rollers, which are basically arranged in a group at an interval of one meter to support the smooth operation of the conveyor belt and coal. A belt conveyor is equipped with about thousands of load-bearing roller groups, resulting in a large number of rollers. Therefore, roller damage is the most common and most likely to occur. After the roller is damaged, it must be repaired and replaced in time to ensure the continuous and trouble-free operation of the belt conveyor and the coal unloading volume of the port.

[0003] At present, the columns of the roller frame that carries the roller group are made of channel steel. A slot for installing the roller is opened vertically in the middle part of the channel steel. The two columns are connected by angle steel. Two brackets are welded on the angle steel, and roller installation slots are opened respectively. The rollers can be installed in the corresponding slots from top to bottom. Three rollers form a groove, so that the conveyor belt is grooved to ensure a large and stable coal transportation volume. However, once the roller is damaged, the conveyor belt pressed on the roller needs to be stretched to replace the roller. In order to ensure that the conveyor belt runs stably and does not slip under heavy load, the tension of the conveyor belt is relatively large. Generally, two maintenance workers are required to support the belt together or tools such as cranes are required to assist. If the space for the conveyor belt to be stretched is limited in the guide trough or the discharge port, the roller frame needs to be dismantled and laid down, and then the damaged rollers need to be replaced. There are problems such as long roller replacement time, high labor consumption, and great impact on production.

[0004] In order to reduce the difficulty and workload of replacing rollers and improve work efficiency, it is very necessary to improve the existing belt conveyor bearing roller frame. Utility Model Content
