Description

(54) TELESCOPIC BELT CONVEYOR

one

The invention relates to the field of lifting and transport machinery, in particular to telescopic belt conveyors used to transport various materials during tunneling or mine workings.

A telescopic belt conveyor is known, which comprises a belt supported on rollers supported on a lever system 1.

However, the design of the conveyor is difficult and when extending the sections the roller supports do not provide a stable position of the belt.

Also known is a telescopic belt conveyor containing a load carrying tape, an envelope of the drive and tension drums and located on the upper and lower roller supports mounted on axles fixed to the sliding hinge-lever mechanism mounted on a stand having a fixed and sliding section 2.

The disadvantage of such a conveyor is the unstable position of the movable section when changing the length of the conveyor, the bulkiness of the structure, and the impossibility of maintaining the perpendicular position of the roller carriages relative to the longitudinal axis of the belt during its reverse movement.

The pawn of the present invention is to provide a stable position of the sliding section, as well as a stable position of the roller bearing in the reverse movement of the load-carrying tape.

To achieve this goal, the axes of the axles of the upper and lower roller supports are equipped with road rollers, and the fixed and extendable sections are telescopic, parallelly arranged, guides in which the roller wheels are installed, while the telescopic guides for the upper roller bearings are mounted on sections that can be moved their height.

FIG. 1 shows a telescopic belt conveyor, general view; in fig. 2 — telescopic extension section in a compressed state; in fig. 3 - the same in the extended state; in fig. 4 - section aa on figZ. A telescopic belt conveyor includes a load-carrying tape 1, which bends around the end drum 2, fixed on the shield 3, and the drive drums 4, 5, mounted on the frame 6 and higher in the haulage or shaft shaft. On the lower branch of the conveyor there are drums 7 and 8, with the help of which a loop is formed, ensuring its elongation when extending the conveyor. The positioning of the conveyor includes a stationary section and a sliding section consisting of st. Amps 9 and pivotally connected levers 10, forming a system of the Nurenberg scissors type. In the places where the hinged joints of the levers 10 are installed, there are roller-supports 11 for supporting the upper working branch of the belt and roller-bearings 12 for supporting the lower empty branch. At the ends of the axles of the roller-bearings 11 and 12, additional running rollers 13 are fixed, located in the horizontal telescopic guides of the upper 14, 15 and low 16, .17. The rails 15 are secured with retainers 18, which are inserted into the vertical grooves of the pillars 9. To prevent the transport cargoes from passing through the rails 14 and 15, the sides 19 and 20 are fixed on top. The conveyor is operated as follows. Before installing the conveyor, first of all, a shield passes through the shield, which makes it possible to install the frame 6 and fixedly and slidably, then store the tape (Fig. 1). Before the start of operation, the telescopic system with levers 10 is in a compressed state (Fig. 2) and the guides 14, 15 are in a lateral position. So, as the drum 2, the guides 14, 16 and the end lever 10 are fastened to. shield 3 (Fig. 3), then with the forward movement of the shield is moving apart the levers 10, the movement of the drum 7 and increase the length of the conveyor. In this case, the latches 18, together with the guides 14 and 15, under the action of the rollers 13 move down in the slots of the pillars 9. When the loop loop is completely selected, the blade loops the tape, inserts the x: X / 4VV / x strip and forms a new loop, after which continues to increase the length of the conveyor as described above. With the full release of the levers 10, the latch 18 rests on the lowest position of the vertical groove of the post 9, after which it is necessary to compress the propulsion system and introduce additional sections. In the proposed conveyor, a stable fixed position of the movable section of the conveyor is provided, as well as maintaining the perpendicular position of the roller carriages relative to the longitudinal axis of the belt when reversing the conveyor to deliver the fastening materials to the bottom. Claims of the invention. A telescopic belt conveyor containing a load carrying tape, an envelope of drive and tension drums and located on the upper and lower roller supports mounted on axles fixed on a sliding hinged-lever mechanism mounted on a stand with a fixed and sliding section, with a separate hinge mechanism. that, in order to ensure a stable position of the sliding section, as well as a stable position of the roller, when reversing the movement of the research institute of the load-carrying tape, the ends of the axes of the upper and lower rollers provide the traveling rollers, and the fixed and extending sections are telescopic, parallelly arranged, guides in which the running rollers are installed, while the telescopic guides for the upper roller supports are mounted on the sections with the possibility of movement along their height.
