Abstract

FIELD: machine building.

SUBSTANCE: in disclosed here apron conveyer links of leaf chains of intermediate drives are arranged opposite to one another along width of pull member. These links are interconnected with "П"-shaped beams, on upper cross bars of which there are secured straps out of elastic material interacting with external surface of a deck of the leaf chain. The leaf chains of an upper branch of the pull member are arranged in spans between a driven sprocket and tightener; they interact with supports of sliding or with rollers. Also, cases of bearings of the driven sprocket and tightener and the said supports of the intermediate drive are mounted on the frame; the frame is secured to poles of the conveyer and can be set off in vertical plane relative to them.

EFFECT: increased reliability of operation of apron conveyer of extended length.

Description

The invention relates to continuous mine transport, in particular to main plate conveyors.

Known plate conveyors containing a plate tape consisting of a deck attached to two traction chains with road rollers with the possibility of their movement along the rails mounted on the racks of the frame (Shahmeister L.G., Zarman L.N. Main underground conveyors. M .: Subsoil, pp. 93-96, Fig. 36c, 1968).

However, a disadvantage of the known conveyors is the limited length.

The intermediate drive of a plate conveyor is known, which contains a traction unit that is endlessly mounted on the drive and tension sprockets and mounted on the frame, including plate chains with their fists fixed on them, with the possibility of fists interacting with the conveyor traction chains (Ibid., P.99-100, Fig. 39 and 40).

The disadvantages of the known intermediate drive of the plate conveyor are the design complexity, the possibility of dynamic loads when the fists of the intermediate drives interact with the conveyor traction chains, the difficulty of synchronizing the operation of the intermediate drives when several intermediate drives are sequentially installed on the conveyor, which reduces the reliability of the plate conveyor with its extended length.

The technical result of the invention is to increase the reliability of the plate conveyor of increased length, equipped with intermediate drives.

The technical result is achieved due to the fact that in a plate conveyor containing a plate belt consisting of a deck attached to two traction chains with track rollers with the possibility of their movement along rails mounted on racks, intermediate drives, each of which consists of an endlessly closed on drive and tension sprockets of the traction body, including plate chains, with the possibility of interaction of the traction body with a plate ribbon, according to the invention placed against each other the width of the traction body, the links of the plate chains are interconnected by U-shaped beams with removable overlays made of elastic material fixed to their upper crossbars with the possibility of their interaction with the outer surface of the plate strip flooring, and the plate chains of the upper branch of the traction body in the spans between the drive and tension sprockets with the possibility of their interaction with bearings, while the bearing housing of the drive and tension sprockets and the said bearings of the intermediate drive are mounted on p Ame with the possibility of its displacement in a vertical plane relative to the racks of the conveyor and fixing on them using screw mechanisms. U-shaped beams with overlays made of elastic material can be placed on each pair of links of plate chains or at a distance from each other that is a multiple of the pitch of the links of the traction chains along the length of the intermediate drive circuit. As supports for the lamellar chains of the intermediate drive, sliding bearings or rollers can be adopted.

The plate conveyor is shown in FIG. 1 — a side view of the load-bearing branch of the plate belt and with sliding bearings for the plate chains of the intermediate drive and overlays for their continuous placement, in FIG. 2 - the same, with supports in the form of rollers and overlays for their intermittent placement relative to each other, figure 3 is a section aa in figure 1.

The plate conveyor contains a plate belt, consisting of a deck 1, attached to two traction chains 2 and 3 with track rollers 4 and 5 with the possibility of their movement along rails 6 and 7, mounted on racks 8 and 9. On frames installed on racks 8 and 9 10, intermediate drives are placed under the load-bearing branch of the strip tape. Each intermediate drive consists of lamellar chains 13 and 14 of the traction body that are endlessly closed on the drive 11 and tension 12 sprockets. At the same time, the links of the plate chains 13 and 14 located opposite each other across the width of the traction body are interconnected by U-shaped beams 15 with removable overlays 16 made of elastic material fixed to their upper crossbars with the possibility of their interaction with the outer surface of the deck 1 of the plate tape.

Lamellar chains 13 and 14 of the upper branch of the traction body of the intermediate drive in the spans between the drive 11 and the tension 12 sprockets are placed with the possibility of their interaction with the supports. As supports for the lamellar chains 13 and 14 of the intermediate drive, sliding bearings 17 of antifriction material (FIG. 1) or rollers 18 (FIG. 2) can be adopted. In this case, the housing 19 and 20 of the bearings of the drive 11 and the tension 12 of the sprockets and the said supports 17 or 18 of the intermediate drive are mounted on the frame 10 with the possibility of displacement of the frame 10 in a vertical plane relative to the struts 8 and 9 of the conveyor and fixing on them using screw mechanisms 21. P -shaped beams 15 with overlays 16 of elastic material can be placed on each pair of links of the plate chains 13, 14 (Fig. 1) or at a distance l from each other, a multiple of step S of the arrangement of links of the traction chains 13, 14 along the length of the intermediate drive circuit (FIG .2). The shaft of the drive sprocket 11 is kinematically connected to the intermediate drive motor (not shown).

The plate conveyor operates as follows. The traction force of the plate tape is transmitted along with the head drive (not shown) also by the intermediate drives. From each intermediate drive, the traction force of the plate tape is transmitted due to friction between the plates 16 of elastic material and the deck 1. In this case, the necessary pressing force of the plates 16 of elastic material to the deck 1 is ensured by the appropriate placement of the frame 10 with the intermediate drive in a vertical plane relative to struts 8 and 9 of the conveyor using screw mechanisms 21, which ensures the necessary lifting of the plate chains 13 and 14 with the lining 16 attached to them and their pressing with the necessary perpetuate violence from the bottom to the deck 1. Due to the friction transmission belt traction plate eliminates the need for strict synchronization of all intermediate drives. This provides the necessary total traction required for the movement of the plate tape.

Distinctive features of the invention provide increased reliability of the plate conveyor of increased length, equipped with intermediate drives.
