Description

Technical Field

[0001] This invention relates to the field of material conveying, and more specifically to a replacement support device for idler rollers of a mining conveyor belt. Background Technology

[0002] Belt conveyors are one of the main production equipment in coal mines, especially large-scale modern coal mines. A belt conveyor is a continuous conveying machine that uses flexible conveying as the material carrying and traction component. The conveyor belt rotates around a drive drum and a redirecting drum, with several idlers supporting the upper and lower branches between the two drums. In operation, material is placed on the conveyor belt, and the friction between the drive drum and the conveyor belt pulls the belt and the material along. During the use of a belt conveyor, idlers are consumable parts and need to be replaced regularly. When damage occurs, they must be replaced promptly to maintain the operation of the belt conveyor.

[0003] Currently, there are no special tools for replacing idlers on belt conveyors. When replacing idlers, a combination of tools such as jacks, hand hoists, and support beams is usually used, which requires a lot of manpower and is labor-intensive.

The support belt provided by rope 16 and roller 19 does not affect the use of the conveyor belt, but it does affect the removal of the idler rollers. When removing the idler rollers, the aforementioned mechanism can first rotate screw 26, which drives the rectangular column 28 and lifting seat 29 upwards until they abut against the idler roller frame. Then, rotate the screws 30 on both sides, which drive the column along the rectangular groove 2 until the two clamping plates 31 clamp the idler roller frame. Next, separate the idler roller frame from the conveyor frame, and then rotate screw 26... 6. This causes the lifting seat 29 and the idler frame to move downwards.
