The invention relates to mine the transport of continuous action, namely to the main plate conveyors of increased length.

Known plate conveyors, plate containing a tape consisting of flooring, attached to the two traction chains with the traction rollers with the possibility of movement along the guides attached to the frame (Sagmeister L.G., Sarman LN. Main underground conveyors. M., Nedra, pp.93-96, 36, 1968).

However, a disadvantage of the known conveyors is limited in length, limited traction possibility of the end of the drive.

Known plate conveyor, a plate containing a tape consisting of flooring, attached to the two traction chains with the traction rollers with the possibility of movement along the guides attached to the frame, the intermediate actuators, each of which consists of the set on the frame indefinitely closed on the drive and tension sprocket traction unit including a plate chain attached to them fists interoperable with fists traction chain conveyor (ibid, s-100, 39 and 40).

The disadvantages of the known plate-type conveyor with intermediate drives are the complexity of the construction, the possibility of dynamic loads when interacting cool the Cove intermediate drives the traction chain conveyor, the difficulty of ensuring synchronization of the intermediate actuators for sequential installation on the conveyor intermediate drives, which reduces the reliability of the plate conveyor with increased length.

Famous adopted for the prototype plate conveyor, a plate containing a tape consisting of flooring, attached to the two traction chains with the traction rollers with the possibility of movement along the guide rails fixed on the racks, smart actuators, each of which consists of infinitely closed on the drive and tension sprocket traction unit including a plate circuit, interoperable traction unit with plate tape placed against each other across the width of the traction unit parts of the plate circuits connected between a U-shaped beams attached to their upper rungs removable pads of elastic material with the possibility of their interaction with external the surface of the deck plate of the tape, and the plate circuit of the upper branches of the traction unit in the spans between the drive and idler sprockets placed with the possibility of their interaction with the supports, with the bearing housing of the drive and idler sprockets and said support intermediate actuator mounted on the frame, with the possibility of displacement of an upright plane relative to the rack conveyor and fixing them by means of screw mechanisms, in the gaps between the traction chain plate belt and plate circuits of the traction unit of the intermediate drive and with minimum clearances relative to the deck plate of the tape in the span between the drive and idler sprockets of the intermediate drive brackets rack conveyor fixed magnets. U-shaped beam with a lining of elastic material can be placed on each pair of link plate chains or at a distance from each other by a multiple step arrangement of the links of the traction chain length of the intermediate circuit of the drive. As supports for the plate circuits of the intermediate actuator accepted sliding bearing or rollers (RF Application No. 2009146670 from 15.12.2009,, IPC E21F 13/08, B65G 19/26).

However, in the construction of the intermediate drive known plate-type conveyor is not fully used its capabilities towards improving implemented them traction.

The technical result of the invention is to increase the tractive effort implemented by an intermediate drive.

This frame may be spring-loaded in its lower or upper parts with the appropriate placement of the brackets for the springs.

Plate conveyor is presented in figure 1 is a longitudinal section through the carrying branches plate tape with spacer slides for the plate circuits of the intermediate drive and overlays with their solid placement along the length of the traction circuit, figure 2 - section a-a of figure 1.

Plate conveyor plate contains a tape consisting of deck 1, attached to the two traction circuits 2 and 3 with the driving rollers 4 and 5 with the possibility of movement along the guides 6 and 7, secured to the uprights 8 and 9. On installed on the racks 8 and 9 frames 10 under load-carrying branch plate tape placed intermediate drives. Each intermediate is rived consists of infinitely closed on the drive 11 and tensioning the 12 stars of the plate circuits 13 and 14 of the traction unit. Placed against each other across the width of the traction unit parts of the plate circuits 13 and 14 are interconnected U-shaped beams 15 attached to the upper rungs of replacement pads 16 of elastic material with the possibility of their interaction with the external surface of the deck plate 1 tape. Plate chain 13 and 14 of the upper branches of the traction unit of the intermediate actuator spans between the drive 11 and the tension 12 posted by asterisks, with the possibility of their interaction with the supports slide 17 of the antifriction material or rollers (not shown). The frame 10 has mounted on it the chain traction body 2, 3 is posted with the possibility of displacement in a vertical plane relative to the fixed guides 18 and 19, secured to the uprights 8 and 9 of the conveyor, and is spring-loaded to them by means of helical compression springs 20 and 21 based fixed on the rails 18 and 19 of the brackets 22 and 23. The brackets 22 and 23 mounted on the uprights 8 and 9 can be offset relative to them in the vertical plane and fixation using screw mechanisms 24 and 25. In the space between the traction chains 2 and 3, the plate of the tape and plate circuits 13 and 14, the top branches of the traction unit of the intermediate drive and with minimum clearances relative to the deck plate 1 tape in the span between the drive 11 and the tension 12 star is AMI intermediate drive posted by magnets 26 and 27, secured to the brackets 28 and 29 of the frame 10. When the rigidity of the springs 20 and 21 adopted from the condition that their total work effort, the value of which is equal to the sum of the weight of the deck plate 1 tape of appropriate length with traction ropes 2, 3 and driving rollers 4, 5 and total effort generated by the magnets 26 and 27. Depending on the geometric parameters of the pipeline and conditions accommodate intermediate drives their frames 10 may be spring-loaded (20, 21) in its lower part (figure 1) or in the upper part (2) with the appropriate placement of the brackets 22 and 23 for springs 20, 21 on the guides 18 and 19.

The shaft drive sprocket 11 is kinematically connected to the engine of the intermediate actuator (not shown). 30 - transported cargo.

Plate conveyor operates in the following manner. Traction plate tape is passed along with the head actuator (not shown) intermediate drives. From each intermediate drive traction plate tape is transmitted through friction between the pads 16 of elastic material and flooring . Preliminary contact force plates 16 of elastic material to the Board 1 is provided by a corresponding displacement of the frame 10 with the intermediate actuator in a vertical plane relative to the racks 8, 9 of the conveyor by means of screw mechanisms 24 and 25, which provides the necessary lifting plate circuits 13 and 14 attached to them by the plates 16 and provided with the necessary force from the bottom to the deck 1. Additional contact force deck 1 to the pads 16 of the traction unit is achieved through the interaction of ferromagnetic material flooring 1 with magnets 26 and 27, and also due to the cumulative efforts of the compression springs 20 and 21. Therefore, the total force of the pressing plates 16 to the deck 1 and passed the plate to the belt traction force increase substantially. Thus due to the mounting of the magnets 26, 27 by means of brackets 28, 29 on the frame 10, the magnetic efficiency of the pressing plates 16 to the deck plate 1 tape increases due to the constant minimum clearance between the magnets 26, 27 and cover plate 1 of the tape at any location in the vertical plane. The presence of compression springs 20 and 21 at the recommended choice of their rigidity in combination with the magnets 26 and 27 provides the intermediate transfer drive traction, the value of which is more than twice the traction force, Elisheva prototype.
