    • 专利摘要:
    A single chain scraper conveyor comprises a trough having first and second straight sections disposed at angles to each other and an intermediate curved section between and joining the first and second straight sections. The intermediate section has an inner curved edge and an outer curved edge, and the trough has an opening along the inner curved edge. An endless chain is centered in and movable along the trough, and it carries a plurality of flights which extend across the chain at spaced locations along its length. Each flight has an inner end which moves around the inner curved edge of the intermediate curved section during operation. A deflector wheel is rotatably mounted adjacent the intermediate section, and it includes a periphery that is parallel to the inner edge, on which a plurality of heads are pivotally mounted at spaced circumferential locations. The heads include surfaces having V-shaped grooves or receiving recesses into which the inner end of each flight may engage. When engaged, the flight is guided by the head in its pivotal connection to the guide wheel around the inner edge of the intermediate curved section.

    专利说明:

    The invention relates to mine conveyor transport, namely to single-chain scraper conveyors having a bend in the horizontal plane.
    The angular groove of a single-chain scraper conveyor is known, which includes semicircular sections in which the scrapers fixed on the upper and lower branches of the chain are placed, interacting with the ends with rotating wheels mounted on the vertical axis C].
    With this implementation, significant loads are created on the elements of the conveyor, which reduces its durability. ten
    Another angular groove of one chain scraper conveyor is known, including sections curved in the form of a round segment, in which scrappers fixed on the upper and lower branches of the chain are placed, the middle part of the scrapers, 20 which rest inside the curve with the ends passing on the segments of the circle of the swivel wheel mounted on the axis in the plane segments of sections and having on po2.
    • the surface of the end part of the groove to accommodate the ends of the scrapers [21.
    However, there occurs a tilting forward of the free ends of the scrapers located outside the curve at an angle defined by the difference of the path between the free ends of the scrapers and the adjacent ends of the scrapers. The free ends of the scrapers when passing through the curve should make a longer way than the adjacent ends of the scrapers. The same applies to the scraper chain and thus to the middle of the scraper. Taking into account the fact that the scrapers fit exactly radially into the zone of the curve, it is necessary to compensate for the tilting of the free ends of the scrapers. This is done by suddenly moving the adjacent ends of the scrapers forward to compensate for the difference in path between the free and adjacent ends of the scrapers. The sudden forward movement of the adjacent ends of the scrapers is carried out when passing through a curve zone when the thrust forces acting on the chain and the resulting reaction force of the adjacent end of the scraper 3 1 755191
    become so large that they lose the friction between the corresponding end of the scraper and the recess. This leads to periodic pauses of the chain with an increase in the force of thrust and 5 twisting forces, followed by sudden loading. Because of this, and also because of the fact that the chain in front of and behind the grips in the curve area runs at a different angle to compensate for the difference in the path, the service life of the truss is reduced. In addition, a sudden movement of the adjacent ends of the scrapers leads to increased wear and may cause a rock shaft.
    The aim of the invention is to improve the long-evechnosti 15 'of the conveyor.
    This goal is achieved by the fact that the end part of the swivel wheel is made of turning heads located on a distance equal to the pitch of the adjacent ends of the scrapers 2 θ s and installed with the possibility of rotation around axes parallel to the axis of the turning wheel. In this case, the surface of the recess, and which the ends of the scrapers rest on, is wavy. In addition, the corner corner is equipped with an element for returning the swiveling tin, made in the form of a cleaning rod: and or a spring leaf.
    FIG. 1 shows a corner chute of a single chain scraper conveyor, top view; on 3 θ {) ig. 2 - section A — A of FIG. one.
    Scrapers 1 are attached to an endless chain I and are located in channel 3 with sections 4 formed from a circular segment, with the scrapers 1 of the upper or lower branches of the chain in the circular segment of sections 4 resting in the radial position by the ends 5 located inside the curve th passing through the hole 6 of the side wall 7 into the chute 40 3 a portion of a circle located in its plane of movement of the swivel wheel 8. The swivel wheel 8 has circumferentially spaced at a distance equal to step T the adjacent ends of the scrapers 5 and ustanovlen- nye 45 rotatably extending parallel to the wheel axis 9 pivot axis 10 of the head 11c is disposed on the recesses 12 circumferentially disposed to the inner side of the ends of the scrapers 5. The rotation angle a of the swivel heads 11 is equal to or more than 50 than the predetermined angle of rotation value of the path difference Δ5 between the free ends of the 13 scrapers located outside the curve and the ends of the 5 scrapers adjacent inside the curve. The swivel heads are made in the form of partial segments of the grooved profile, and their notch 12 is made wavy, as a result of which a better contact is provided by the notches located inside the curve with the ends of 5 scrapers. The swivel heads can be attached around the circumference of the swivel wheel 8 with the possibility of replacement and made of wear-resistant material, such as, for example, bleached cast iron, cast steel, etc. The swivel heads 11 between the exit and inlet portions of the scrapers 1 at the swivel wheel interact with the element 14 for returning the swivel heads made of a cleaning brush or spring sheet.
    The scrapers entering the zone of the curve, with the ends located inside the curve, run over the swivel heads and at the same time are centered in the circumferentially spaced grooves in the radial position. With the passage of the curve area, the swivel heads are stacked in accordance with the path difference to be compensated between the free ends of the scrapers and the adjacent ends of the scrapers, so that a uniform passage of the curve zone is ensured and therefore the scrapers are held in this zone in the radial position. Sudden movement of the scrapers forward is eliminated. This ensures uniform load on the circuit. The fasteners, through which the scrapers are connected to the chain, are also significantly unloaded. The wear between the adjacent ends of the scrapers and the swivel wheel is greatly reduced.
