(54) СЕКЦИЯ УГЛОВОГО СКРЕБКОВОГО КОНВЕЙЕРА(54) SECTION OF ANGULAR SCRAPER CONVEYOR

1one

Изобретение относитс к шахтному конвейерному транспорту и может быть использовано в конструкци х угловых скребковых конвейеров, предназначенных дл транспортировани груза с разворотом под пр мым углом, исключающим перегрузку, в частности к забойным конвейерам при отработке угольных пластов.The invention relates to mine conveyor transport and can be used in the construction of angular scraper conveyors intended for transporting cargo with a turn at a right angle, excluding overload, in particular to bottomhole conveyors when mining coal seams.

Известен скребковый конвейер дл транспортировани угл вдоль очистного забо и по выемочному штреку, один конец которого состоит из нескольких поворотных секций рештаков, переход щих по радиусу закруглени в выемочный штрек, в котором расположена приводна головка 1.A scraper conveyor is known for transporting coal along the clearing intake and along the excavation drift, one end of which consists of several rotary sections of the pan that pass along the radius of curvature into the excavation drift in which the drive head 1 is located.

Недостатком данной конструкции конвейера . вл етс возникновение при его работе больших сил трени между концами скребков и направл ющими конвейерного става, расположенными с внутренней стороны закруглени , что приводит к перекосу, поломке скребков и выворачиванию их из направл ющих .The disadvantage of this design of the conveyor. is the occurrence during its operation of large friction forces between the ends of the scrapers and the guides of the conveyor rod, located on the inner side of the rounding, which leads to a distortion, breakage of the scrapers and their turning out of the guides.

Известен также скребковый конвейер.секци которого имеет желоб с днищем, пологий утюг дл холостой ветви и поворотныйAlso known is a scraper conveyor. A section of which has a gutter with a bottom, a gentle iron for an idle branch and a swivel

обводной диск дл грузовой ветви конвейера 2.bypass disk for cargo branch conveyor 2.

При работе конвейеров концы скребков, опира сь на диски, привод т их во вращательное движение и перемещаютс вместе с ними. Силы трени концов скребков об обводные диски в этой конструкции сведены до минимума, но перекос, выворачивание из направл ющих и поломка скребков при этом не устран етс .When the conveyors operate, the ends of the scrapers, resting on the discs, bring them into rotational motion and move with them. The forces of friction of the ends of the scrapers to the circumferential discs in this design are minimized, but skewing, turning out of the guides and breaking the scrapers is not eliminated.

При работающем конвейере в круглозвенной цепи при огибании ею обводных висков, With a running conveyor in a round link chain, when it bends around bypass temples,

10 возникают значительные по величине центростремительные силы, которые передаютс на обводные диски через скребки, перекашивают , ломают скребки и выворачивают их из направл ющих. Все это ухудщает работу углового скребкового конвейера, снижает его надежность и резко повышает нагрузки на электропривод.10, significant centripetal forces are generated, which are transmitted to the bypass discs through the scrapers, warp, break the scrapers and turn them out of the guides. All this worsens the work of the angular scraper conveyor, reduces its reliability and dramatically increases the load on the electric drive.

Claims

The purpose of the invention is to improve the reliability of the angular scraper conveyor, reducing the loads on the electric drive by eliminating the transmission of centripetal forces to the bypass discs through the scrapers. This goal is achieved in that in the corner scraper conveyor, the section of which has a chute with a bottom, a gentle iron for the idle branch and a swiveling bypass disk for the cargo branch of the conveyor, the swiveling bypass disk is located at the bottom of the cargo branch and is made with supporting cams for interacting with the chain , with the supporting cams mounted along the edges of its upper plane and protruding above it. In addition, the installation step of the support cams may be equal to the installation step of the scrapers on the conveyor chain. FIG. 1 shows the proposed section of the angular scraper conveyor, general view; in fig. 2 shows section A-A in FIG. 1. The corner section includes a chute 1 with a bottom flat iron 2 for an idle branch and a bypass disk 3 for a cargo branch of the conveyor with fists 4 protruding along its edge, on which the round link chain rests 5. Fists 4 have slots 6 that include chain link 5. The bypass disk rotates freely on the bearings 7, mounted on the axis 8, which is mounted in the housing 1 of the corner section. The bypass disk occupies a portion of the working section of the cargo trough 9 and is its bottom. The rotation of the bypass disk occurs by engaging the fists with 4 links of the moving chain 5. During operation of the angular conveyor, the round-link chain 5 bends around the bypass disk 3 and directly rests on the raised fists 4. Scrapers 10 pass freely between the fists, which eliminates the possibility of rolling and breaking their, improves the work of the angular conveyor and reduces the load on the electric drive and, in addition, eliminates breakage scrapers. Claim 1. A section of an angular scraper conveyor comprising a traction chain with scrapers, a chute with a bottom, a gentle iron for the idle branch of the conveyor and a rotary bypass disk for the cargo branch of the conveyor, characterized by the fact that The bypass disk is located at the bottom of the cargo branch and is made with supporting cams for interacting with the chain, with the supporting cams mounted and protruding along the edges of the upper plane of the rotary bypass disk. 2. The section of claim 1, wherein THAT the step of installing the support cams is equal to the step of installing the scrapers on the conveyor chain.
