Description

Известно рабочее оборудование одноковшового экскаватора-драглайна, включаю Шее стрелу, ковш, поворотную опору с подвижной обоймой, т говьгй канат, верхние и нижние блокн., I Цель предлагаемого оборудовани  - уве личение долговечности каната. Достнгаетс  она тем, что верхние блоки оборудовани  установлены на общую с подвижной обоймой поворотную опору. На чертеже показано описываемое оборудование . Оно содержит нижние блоки 1, верхние блоки 2, т говые канаты3, поворотную опору 4, стрелу 5, подвеску 6 и подвижную обойму 7. Верхние блоки смонтированы на свободном конце опоры 4 соосно с подвижной обоймой 7 стрелового полиспаста 8, а неподвижна  обойма 9 - на надстройке Ю Угол наклона опоры 4 н ее высота выбираютс  из условий обеспечени  оптимальных нагрузок в подвеске и стреле, а также чтобы перпендикул рна  оси опоры 4 составл юща  т говых канатов 3 была меньше соответствующей составлгюшбй, передаваемой от стрелы 5 через часть подвески 6... . / Поэтому при работе йсскаватора попнспастна  часть подвески посто гано раст нута , но нагрузки в полиспасте 8 по ески при каждом отрыве ковша от в процессе копани  благодар  разгруж щему вли нию т говых канатов меньше, в известных конструкци х. и 3 о б р е т Формула е н и   Рабочее оборудование одноковшсшого экскаватора-драглайна, включающее стрелы, ковш, п жоротную опору с подвижной обоймой , т говый канат, верхние и нижние блоки , отличающеес  тем, что, с целью увеличени  долговечности каната, верхние блоки оборудсжани  установлены на общую с подвижной обоймой поворотную опору.The working equipment of a single-bucket dragline excavator is known, including a neck boom, a bucket, a rotary support with a movable yoke, a haul rope, upper and lower blocks, I the purpose of the proposed equipment is to increase the durability of the rope. It is achieved by the fact that the upper units of the equipment are mounted on a pivot bearing common with the movable yoke. The drawing shows the described equipment. It contains lower blocks 1, upper blocks 2, pull ropes 3, swivel support 4, boom 5, suspension 6 and movable holder 7. Upper blocks are mounted on the free end of support 4 coaxially with movable holder 7 boom polyspast 8, and the fixed holder 9 - on the superstructure Yu. The angle of inclination of the support 4 n is selected from the conditions for ensuring optimal loads in the suspension and boom, and also that perpendicular to the axis of support 4 the component of the pull ropes 3 is less than the corresponding component transmitted from the boom 5 through part of the suspension 6 .. . / Therefore, when working with an isscavator, the suspension part of the suspension is constantly stretched, but the load in the polyspast is 8%, with each detachment of the bucket from the digging process due to the unloading effect of the hauling ropes less, in known structures. and 3 of the formula. Formula and Working equipment of the same excavator dragline, including arrows, bucket, pivot bearing with a movable yoke, hauling rope, upper and lower blocks, characterized in that, in order to increase the durability of the rope, the upper equipment units are mounted on a pivot bearing common with the movable yoke.
