Belt conveyor buffering device and manufacturing method thereof

Abstract

The invention discloses a belt conveyor buffering device and a manufacturing method thereof. The belt conveyor buffering device comprises a buffer bed B and macromolecule roller type bottom roller sets; the number of the macromolecule roller type bottom roller sets is five, each macromolecule roller type bottom roller set is installed at the front end and the rear end of the buffer bed B and the gap of a middle bottom plate, the two ends of the buffer bed B are fixedly connected to a belt conveyor support through connecting bolts B, and a buffer spring B used for relieving material impact is additionally arranged in the middle of the belt conveyor support. The adjustable macromolecule roller type bottom roller sets are arranged to be matched with the buffer bed B, so that the buffer requirement during normal production is met, and the loss of friction kinetic energy is reduced; and particularly, under the conditions that the belt is pressed to stop and the heavy load cannot be started, the macromolecule roller type bottom roller sets are adjusted and lifted through adjusting screws, the friction form of the belt and the supporting surface is changed, friction force is greatly reduced, safe operation of the heavy load is guaranteed, and the overall structural design is safe, reliable, simple and effective.

Description

technical field [0001] The invention relates to the technical field of heavy-duty belt conveyors for mine transportation, in particular to a belt conveyor buffer device and a manufacturing method thereof. Background technique [0002] In mine transportation, a large number of belt conveyors are used for the transportation and transportation of ore and waste rock. During the transfer process of the conveyor, in order to slow down the impact of the material on the conveyor belt, a buffer device will be installed at the point where the material falls. [0003] At present, most of the buffer devices commonly used in belt conveyors are buffer idlers 3 or buffer beds A4, such as figure 1 , figure 2 shown. The buffer roller group 3 is arranged between the tail part 1 of the belt conveyor and the belt conveyor head part 2. The buffer roller group 3 absorbs the impact force weakly and has poor buffering capacity. Under the condition of gravity impact, the roller will fall out of ...

Problems solved by technology

[0005] The object of the present invention is to provide a belt conveyor buffer device and its manufacturing method. By setting the adjustable polymer material buffer bottom roller, it not only meets the buffer requirements during normal production, but also reduces the loss of frictional kinetic energy; especially when the belt is pressed to stop , When the heavy load cannot be started, use the adjusting screw to adjust and raise the bottom roller group, change the friction form between the belt and the support surface, greatly reduce the friction force, ensure the safety of heavy loads, avoid manual cleaning, and eliminate potential safety hazards to solve the problem. There are problems such as poor buffering capacity caused by insufficient buffering devices of belt conveyors, easy to get stuck when running off-track, large frictional resistance, and difficult to start with heavy loads
