Background

The transfer of ore currently relies primarily on belt conveyors. In order to improve the stability of belt conveying, the belt needs to be supported by a carrier roller below the belt. The bearing roller is easy wearing and tearing after long-time the use, needs regularly to change.

When the belt carrier roller is replaced, the belt is lifted up manually to enable the belt to be separated from the carrier roller, then other operators detach the original carrier roller immediately, install a new carrier roller and finally put down the belt. For example, the sizes of the carrier rollers adopted by the belt conveyor at the ore loading station in the mining area are phi 159 x 465 and phi 159 x 1400, the width of the conveyor belt is 1200mm, at least three carriers are required to cooperate together when the upper carrier roller is replaced each time, four carriers are required when the lower carrier roller is replaced, and when the conveyor belt is lifted upwards, force cannot be applied due to the narrow space at one side of the belt corridor, so that the efficiency is very low. More importantly, in order to lift the conveyer belt, workers often carry on shoulder carrying by using a drill rod, and safety accidents are easy to happen.

Furthermore, two left and right sliding grooves 3 are formed in the upper supporting plate 2, and the sliding grooves 3 are in left and right directions. The connecting rods 5 are two groups, are vertically arranged and correspond to the two groups of sliding grooves 3 one to one. The upper end of connecting rod 5 passes fixedly connected with cross arm 4 behind the spout 3, and lower extreme fixedly connected with bears ring 6.

As shown in fig. 2, the cross arm 4 extends forward and backward, the length of the cross arm 4 in the forward and backward direction is smaller than the length of the sliding chute 3 in the leftward and rightward direction, and the width of the cross arm 4 in the leftward and rightward direction is smaller than the width of the sliding chute 3 in the forward and backward direction, so that the cross arm 4 can pass through the sliding chute 3 upward or can be supported above the upper support plate 2.

The two ends of the lower supporting tube 7 are respectively matched with the two bearing rings 6.

Preferably, the inner hole of the bearing ring 6 is provided with a rubber ring 14, and the rubber ring 14 is in contact with the lower support tube 7, so that the friction force is increased, and the lower support tube 7 is prevented from falling off.

Further, the width of the bearing ring 6 in the left-right direction is smaller than the width of the sliding groove 3 in the front-back direction, so that the bearing ring can conveniently penetrate through the sliding groove 3.

Referring to fig. 4, before replacing the idler, the two ends of the base 1 are placed on the frame 17 of the belt conveyor, and the base 1 is located between the upper belt 15 and the lower belt 16. The connecting rod 5 is then inserted into the chute 3. There are two insertion modes at this time: one is that the connecting rod 5 is rotated by 90 degrees to make the cross arm 4 parallel to the sliding chute 3, then the cross arm 4 is inserted into the sliding chute 3 from bottom to top, and then rotated by 90 degrees to make the cross arm 4 perpendicular to the sliding chute 3; the other method is that the connecting rod 5 is rotated by 90 degrees to enable the bearing ring 6 to be parallel to the sliding chute 3, then the cross arm 4 is inserted into the sliding chute 3 from top to bottom, and then the connecting rod is rotated by 90 degrees to enable the cross arm 4 to be vertical to the sliding chute 3. The staff can select any one installation mode according to the operation space. With the connecting rod 5 in place, the two carrier rings 6 are located below the lower belt 16 with their axes coinciding with each other, whereupon the lower support tube 7 is inserted into the two carrier rings 6.

The base 1 can be provided with a strip-shaped groove corresponding to the sliding groove 3 or other hollow structures are added according to requirements, so that the connecting rod 5 can normally pass through the groove.

When the carrier roller is replaced: the screw head 8 is rotated firstly to jack the jack, the upper supporting plate 2 is driven to ascend, the upper layer belt 15 is lifted, meanwhile, the lower supporting tube 7 is driven by the cross arm 4, the connecting rod 5 and the bearing ring 6 to ascend synchronously, the lower layer belt 16 is lifted, and at the moment, the operation of detaching, maintaining, replacing and the like of the carrier roller can be carried out by a worker.
