(54) РЕШТАЧНЫЙ СТАВ КОНВЕЙЕРА А. Г. БОЙКО(54) RESTRICTABLE CONTAINER A. G. BOIKO

Изобретение относитс к горным машинам, в частности к безразборным забойным скребковым конвейерам.The invention relates to mining machines, in particular to the non-bottomhole scraper conveyors.

Известен решгачный став скребкового конвейера , включающий соедаиенные между собой пикейные рештаки, образующие межреипачные поперечные стыки, и скребковую цепь с поперечными скребками 1 . Рештаки става в плане выполнены пр моугольной формы, образу между собой стыки под углом 90° к оси става так же, как и скребки. Таким образом, оси каждого скребка и линии каждого межрештачдаго стыка совпадают.The grill stand of the scraper conveyor is known, which includes pike lattices connected to each other, which form inter-riped transverse joints, and a scraper chain with transverse scrapers 1. The planner pans in the plan are rectangular in shape, forming between the joints at an angle of 90 ° to the pivot axis in the same way as the scrapers. Thus, the axes of each scraper and the lines of each inter-rash joint coincide.

Однако вьшопнеиие межрештавдых стыков 1ЮД углом 90° отрицательно вли ет на взаимо действие их с жесткими узлами скребковой цепи: соедиюггельное звено - скребок - соедииителыюе звено, которые тоже расположены под углом 90° к той же оси.However, the overhanging of interstitial 1UD joints with an angle of 90 ° negatively affects their interaction with rigid nodes of the scraper chain: a connecting link — a scraper — is a connection between the link, which is also located at an angle of 90 ° to the same axis.

Во врем работы конвейера указанный скреб ковый узел-одномоментно всеми своими соотавл юшймй элементами, переход через мез рештачный став, частично или полностью заклиниваетс в нем. Заклинивание происходит, как установлено на стенде и в натуре, во-первых, During the operation of the conveyor, the indicated scraper unit is simultaneously all its corresponding elements, the transition through the lattice stand, partially or completely wedged in it. Jamming occurs, as set on the stand and in kind, firstly,

вследствие того, «гго иа стыках рештачного става во врем его зксплзатации возникают пороги (осевые сдвиги). Их практически иево можно удерживать гладким,, т.е. без порогов, так как на став непрерьшно циклично воздействутот передвижвдки и перемещающийс выемочный механизм - комбайн или струг; вовторых , вследствие больших габаритов зтого узла, чем габариты т говых цепей за счет выступающих опорных приливов на ооединителных звень х. В результате данный узел работает в более стесненных услови х, чем т говые цепи.due to the fact that when joining the pivotal stand, thresholds (axial shifts) occur during its opening. They can practically be kept smooth, i.e. without thresholds, since by becoming continuously cyclically affected by the movement and the moving excavation mechanism — a combine or plow; secondly, due to the large dimensions of this site, than the dimensions of the traction chains due to the protruding supporting tides at the unified links x. As a result, this unit operates under more constrained conditions than the traction chains.

Все зто обусловливает частичные или полные заклинивани рештачных Iстыков, образу в т говом органе динамические надбавки, причетл таких заклиниваний по длине става может быть несколько. Этим объ сн етс высока частота заклиниваний и порьшов скребковых цепей, а также преждевременный изиос торцовых элементов реплаков.All this causes partial or full seizures of the pan-taps, forming dynamic surcharges in the body, there may be several such seizures along the length of the rod. This explains the high frequency of jamming and pigtails of the scraper chains, as well as the premature izios of the end elements of the replaces.

Claims

The closest of the known solutions is a pan-turn conveyor, which is interconnected by means of pan locks, the ends of which form transverse inter-lattice joints. However, this implementation does not provide a sufficient increase in reliability and durability. The purpose of the invention is to improve the reliability and durability of work. For this end, the ends of the pan are made inclined in the horizontal plane relative to the axis of the crosshead. Such an implementation of a conveyor belt provides more favorable conditions for the interaction of inter-lattice joints with the scraper of the COBO chain. The successive transition of chain elements through oblique junctions with intervals in space and space, even in cases of their violation, eliminates dangerous rigid seals of the scraper chains. The figure shows the proposed conveyor belt. Becoming a scraper conveyor consists of reshs such as 1, made in the plan in the form of a parallelogram joined with each other by means of centering locks 2, a scraper chain including a node: a connecting link scraper; 4 - connecting link 5, and the traction chains 6, Line 7 of the intershatter joint about the axis 8 of the scraper 4 in the e-plane are turned by an angle. The sidewalls of 9 rei.1tak are made with rectangular ends. The bottom of the 10 pan is also a kind of parallelogram. Such a bottom and sidewalls form a parallelogram pan. The angle a of the relative displacement of the junction line of the pantowers and the scraper axis is determined from the condition of providing a successive successive entry and exit of the connecting links 3 and 5 from the inter-row junction and is determined by the leg size and triangle ABC, which must be at least one step t of the link chain . . The simplicity of the design of the proposed pan and conveyor belt as a whole provides the possibility of making them both at the firm's machine-building plants of the mining machine-building industry and at the repair plants of Shnugleprom without any changes in technology and materials. Due to the displacement angle} of the inter-grid joint with respect to the scraper, during the operation of the scraper chain (conveyor), the connecting chain links alternate one after the other and this prevents their jamming, reduces wear of the ends of the pan and connecting links from the dynamic (shock) loads , it allows to increase the labor productivity of workers of the clearing slab by almost 25-30% due to the decrease in the labor intensity of maintenance service, lowering the accident rate from scrapers x chains and wear of the end elements of the pan / Formula of the invention: Bending of the conveyor, including interconnected with the help of padlocks, the ends of which form transverse inter-lattice joints, which distinguish ui-i-ys because, in order to improve reliability and durability, The ends of the pan are inclined in the horizontal plane relative to the axis of the pan-on stand.
