Description
( НАТЯЖНОЕ УСТРОЙСТВО ТЯГОООГО ОРГАНА (TENSIONAL DEVICE OF THE BODY OF THE BODY
1one
Изобретение относитс к оборудованию дл механизации подземной выемки угл .The invention relates to equipment for the mechanization of underground coal excavation.
Известны устройства дл нат жени т гового органа механизма подачи выемочной машины, включающие два гидродомкрата, штоки которых св заны с т говым органом, а штоковые полости св заны с напорной линией посредством гидрозамков f1J .There are known devices for tensioning the traction body of the excavation feed mechanism, including two hydraulic jacks, the rods of which are connected to the traction body, and the rod cavities are connected to the pressure line by means of hydraulic locks f1J.
Heдocтaткotл данного устройства вл етс то, что pacnoj.omeHHe гидродомкратов на выемочной машине не обеспечивает снижение динамических нагрузок.The poorness of this device is that the pacnoj.omeHHe of the hydraulic jacks on the excavation machine does not reduce the dynamic loads.
Наиболее близким по технической сущности вл етс нат жное устройство , включающее два гидродомкрата,. расположенные на концах базы дл перемещени выемочной майданы, штоки, которых св заны с т говым органом, а штоковые полости- св заны с гидроаккумул торами , гидроаппаратуру с / ВИЕМОЧНОЙ МАШИНЫThe closest in technical essence is a tensioning device including two hydraulic jacks. located at the ends of the base for moving the excavation Maidan, the rods, which are connected with the traction organ, and the rod cavities are connected with the hydraulic accumulators, the hydraulic equipment with the TEMPORARY MACHINE
манометром, напорную и сливную линии 2J .pressure gauge, pressure and discharge lines 2J.
Недостатком указанного устройства вл етс то, что наличие обводных звезд не обеспечивает защиту от пиковых нагрузок и снижает надежность.The disadvantage of this device is that the presence of bypass stars does not provide protection against peak loads and reduces reliability.
Цель изобретени - снижение динамических нагрузок и повышение надежности .The purpose of the invention is to reduce dynamic loads and increase reliability.
Указанна цель достигаетс тем, что нат жное устройство т гового органа выемочной машины, включающее два гидродомкрата, расположенные на концах базы дл перемещени выемочной This goal is achieved by the fact that the tension device of the traction body of the excavation machine, including two hydraulic jacks, is located at the ends of the base to move the excavation machine.
ts машины, штоки которых св заны с т говым органом, а штоковые полости св заны с гидроаккумул торами, гидроаппарат/ру с контактным манометром, напорную и сливную линии, снабжено ts machines, the rods of which are connected to the traction organ, and the rod cavities are connected to the hydroaccumulators, the hydroapparatus / py with the contact manometer, the pressure and discharge lines, are equipped with
