The technical problem to be solved by the utility model is how to fill the blank in the prior art, and a supporting device for online replacement of a carrier roller of a belt conveyor is provided.
In order to solve the technical problems, the supporting device for online replacement of the carrier roller of the belt conveyor comprises a screw rod sleeve, an upper supporting rod, a lower supporting rod and a ratchet wrench; the screw rod sleeve is characterized in that two ends of the screw rod sleeve are respectively provided with internal threads with opposite spiral directions, the upper support rod and the lower support rod are respectively provided with corresponding external threads, the corresponding external threads are respectively screwed in the two ends of the screw rod sleeve, a ratchet wheel is arranged in the middle section of the screw rod sleeve, the ratchet wheel wrench sleeve is arranged on the screw rod sleeve and can rotate around the axis of the ratchet wheel shaft, a pawl matched with the ratchet wheel is arranged on the ratchet wheel wrench, the ratchet wheel and the pawl form the ratchet wheel locking device, and the root of the lower support rod is fixed on the bottom clamping seat, so that the screw rod sleeve is characterized in that: the upper carrier roller comprises a carrier roller and two rollers, the middle section of the carrier roller is hinged to the top end of the upper supporting rod through a horizontal shaft, the two rollers are respectively sleeved on two sides of the carrier roller, a bearing is arranged between each roller and the carrier roller, the two rollers can rotate around the axial lead of the carrier roller, the bottom clamping seat comprises an upper plate, a side plate and a lower plate, the upper plate and the lower plate are respectively connected onto the upper edge and the lower edge of the side plate to form a clamping groove, the cross section of the clamping groove is 匚 -shaped, the root of the lower supporting rod is welded to the upper plate, a threaded through hole is formed in the lower plate, and a fastening screw is arranged in the threaded through hole in an internal rotation mode.
When a worker finds that a certain carrier roller of the matched belt conveyor fails, namely, a roller cannot rotate or rotates smoothly or excessively rises temperature mainly due to bearing damage, the supporting device for online replacement of the carrier roller of the belt conveyor is taken out, and a clamping groove of a clamping seat at the bottom is clamped on a cross beam of a saddle frame of the matched belt conveyor beside the carrier roller to be replaced, as shown in fig. 1. Then, the ratchet wheel spanner drives the ratchet wheel and the screw rod sleeve to rotate, so that the upper supporting rod and an upper supporting roller at the top of the upper supporting rod are lifted, finally, the upper supporting roller supports an upper layer belt of the matched belt conveyor, and the upper layer belt is separated from the supporting roller to be replaced, so that the corresponding supporting roller can be replaced.
When the upper carrier roller supports the upper layer belt of the belt conveyor, the upper carrier roller rotates along with the upper layer belt, and the corresponding carrier roller can be replaced without stopping the belt conveyor. The middle section of the supporting rod is hinged to the top end of the upper supporting rod through a horizontal shaft, so that the upper supporting roller can automatically adapt to an inclined upper layer belt and is driven to rotate by the running upper layer belt.
As optimization, the lower end of the fastening screw is connected in the middle of a cross rod, and the whole fastening screw is T-shaped. So designed, it is convenient for manual adjustment.
The supporting device for online replacement of the carrier roller of the belt conveyor has a simple structure, is convenient to carry, can replace a fault carrier roller without online shutdown, and is particularly suitable for being matched with the underground belt conveyor of a coal mine.
