Description

FIELD OF THE INVENTION The invention relates to a hoisting-and-transport machine building, in particular to steeply inclined belt conveyors used to transport bulk materials.

A steeply inclined belt conveyor is known, comprising a belt, an envelope of a driving and tension drum. The cargo branch of the belt is located on the roller, and the lower branch sags freely.

A prerequisite for the use of such conveyors in underground conditions is the lack of contact of the sagging lower branch of the belt with the working soil or metalwork of the gallery, which must be ensured by corresponding tension of the belt on the lower branch 1D.

The disadvantage of this conveyor is the use of rigid tensioning devices, which are not. in the process of work, they allow to compensate the elastic stretching of the tape and the change in its linear weight due to sticking of the transported cargo.

. The closest to the invention in terms of technical essence and effect achieved is a steeply inclined belt conveyor containing a belt with a load-carrying branch located on roller supports mounted on the frame and a loose sag idling branch, a tension drum fixed on the support with the base. The tension drum of the conveyor is fixed on the tension trolley, and the trolley itself is connected with the tension device, 1 which can

0 be performed, for example, in the form of a tensioner

The disadvantage of the known conveyor is cumbersome, large sizes, which requires additional mining operations associated with the device chambers, wells and maintaining them in working condition, error in the work because of losses on

20 friction in a chain hoist when moving a load, difficulty in adjusting the tension, low reliability of operation due to the possibility of wedging of cables in the system of blocks and fitting

25 wells to move the tension load. All this reduces the efficiency of the conveyor.

The aim of the invention is to increase the efficiency of the conveyor.

30 by using the weight of its frame to provide a constant belt tension. This goal is achieved by the fact that in a steeply inclined belt conveyor containing a belt with a load-carrying branch located on a roller-mounted carriage mounted on a frame and a free-hanging idle branch, a tension carriage mounted on a support by the base of the drive drum, the frame is made of sections mounted on a support by means of rollers with the possibility of attaching sections to a tension trolley or to the base of a driving drum. FIG. 1 shows a steeply inclined conveyor belt, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - tensioned trolley with sections. The steeply inclined belt conveyor consists of belt 1 with partitions mi 2, envelope drive 3 and tension 4 drums. The drive drum 3 is fixedly fixed with the base 5 on the support, and the tension drum is mounted on the tension trolley b with the traveling wheels mounted on the support 7 of the conveyor. The load-carrying branch of tape 1 is located on roller 8, and its idle branch slackens. Roller supports 8 are mounted on a frame that is formed by sections 9 with rollers 10 mounted on support 7 and can be moved along it. The support 7 is a guide beam 11 which is suspended from the arch support 12 by means of extensions 13. Sections 9 can be interconnected with each other by means of a bolted joint 14, and also with a tension carriage 6 or The conveyor works as follows. When moving, the tape 1 with partitions 2 bends around the drive 3 and tension 4 drums, sagging on the lower branch between them in a parabola. The constant tension of the belt 1 with partitions 2 and the stabilization of the sag in various modes of operation of the conveyor is ensured by moving the tension drum 4 on the carriage b and the sections 9 associated with it on the rollers 10 along the guide beams 11 due to the horizontal composition the weight of the roller 8 with sections 9 and the tension drum 4 with the cart 6. The tension of the left 1 is adjusted by changing the number of sections 9 connected to the tension drum 4 and by changing the number of sections 9 attached to the base 5 of the drum 2 by means of bolted joints 14. The proposed construction of the conveyor makes it possible to simplify the design of the tensioning device and increase the efficiency of the conveyor by providing a constant boom of the slack idler branch of the belt and creating a direct connection between the tension drum of the conveyor and the movable sections of its frame , reduce the metal intensity of the conveyor by using the pc1m sections and roller support not only to maintain the belt on the load-carrying branch, but also to create additional tension using Their weight. . The invention is a steeply inclined belt conveyor comprising a belt with a load-carrying branch located on the roller carriages mounted on the frame and a loose sagging idle branch, a tension trolley and a drive drum fixed on the support, characterized in that in order to increase the efficiency of the conveyor by using the weight of the frame to ensure constant tension of the belt, pai4a is made of sections mounted on the support by means of rollers with the possibility of connecting sections to the tension trolley or Warping of the drive drum.
