Description

The invention relates to conveyor engineering, namely to intermediate linear drives, and can be used on long-distance conveyor belts of increased length with increased traction capability of the intermediate drive ..

Known for the prototype is an intermediate linear drive of a conveyor belt, comprising a drive belt located under the load-bearing branch of the conveyor belt, the drive belt closed on the drive and tension drums, the upper branch of which is located under the load-bearing branch of the conveyor belt and rests on its roller bearings, and the lower branch is pressed against the roller idle branches of a conveyor belt (V.T. Polunin, G.M. Gulenko. Conveyors for mining enterprises. M: Nedra, pp. 235-236, Fig. 9.4b).

However, the disadvantages of the known linear drive design are the limited amount of traction reported by the load-bearing branch of the conveyor belt and traction reported by the idle branch of the conveyor belt, which necessitates an increase in the length of the linear drive and an increase in the number of pressure rollers placed above its lower branch, or requires an increase the number of intermediate drives, which increases the capital and operating costs of bulk conveyor transport.

The technical result of the invention is to increase the traction forces reported by a linear drive of the load-bearing and idle branches of the conveyor belt.

The technical result is achieved by the fact that in the intermediate linear drive of the conveyor belt containing the drive belt located under the load-bearing branch of the conveyor belt, the drive belt closed on the drive and tension drums, the upper branch of which is located under the load-bearing branch of the conveyor belt and rests on its grooved roller bearings, on the outer surface of the intermediate belt drive with a certain step equal to the spacing of the grooved roller bearings, transverse partitions of elastic or rigid material are fixed and a curved or rectangular transverse profile with rounded upper edges, consisting of three parts - the middle and two side, located with gaps relative to each other with the possibility of ensuring transverse bending of the tape when it is supported by the grooved roller bearings of the conveyor belt, while the lower branch of the belt of the intermediate drive is supported their partitions on the idle branch of the conveyor belt.

The intermediate linear actuator is presented in figure 1 is a longitudinal section, in figure 2 is a section aa in figure 1.

The intermediate linear drive of the conveyor belt contains located under the load-bearing branch of the conveyor belt 1, the drive belt 4 is closed on the drive 2 and tension 3 reels 4. The upper branch of the drive belt 4 is located under the load-bearing branch 1 of the conveyor belt and rests on its grooved roller bearings 5. On the outer surface of the belt 4 intermediate drive with a certain step equal to the spacing of the grooved roller bearings 5, fixed transverse partitions made of elastic or rigid material, curved or rectangular of the transverse profile, consisting of three parts - the middle 6 and two side 7 and 8, located with gaps 9 and 10 relative to each other with the possibility of ensuring transverse bending of the tape 4 when it is supported by the grooved roller bearings 5 of the conveyor belt. The lower branch of the belt 4 of the intermediate drive is supported by its partitions 6, 7, 8 on the idle branch of the conveyor belt 1. The spacing of the transverse partitions 6,7,8 on the belt 4 of the intermediate drive is taken equal to the spacing of the grooved roller bearings 5.

11 - the direction of movement of the load-bearing branch of the conveyor belt 1.

12 - transported cargo.

The intermediate linear drive of the conveyor belt operates as follows. When the drive drum 2 rotates, the traction force from the drive belt 4 is transmitted to the load-bearing branch 1 of the conveyor belt not only due to the friction force between them, caused by the weight of the load-bearing branch 1 of the tape with the transported load 12 placed on it, but also due to the persistent interaction of the belt 4 of the intermediate drive with a load-bearing branch of the conveyor belt 1 due to its deflection under the influence of its own weight and the weight of the transported cargo 12 placed on the belt 1 between the partitions 6, 7, 8 on the belt 4 of the intermediate drive, onto which onesuschaya branch tape 1 is permanently based. The choice of material from which the partitions 6, 7, 8 are made, and the shape of their cross section is taken depending on the physicomechanical properties of the transported cargo 12.

Distinctive features of the invention provide a significant increase in traction exerted by the linear drive of both the load-bearing and idle branches of the conveyor belt, which reduces the number of intermediate linear drives on the main belt conveyor or reduces their length, as well as reduces the number of pinch rollers on the lower branch of the drive belt, with a corresponding reduction in capital and operating costs.
