Description

Известно рабочее оборудование экскаватора - пр ма  лопата, включающее стрелу со стойками и головные блоки с осью.The excavator’s working equipment is known — a shovel including a boom with stands and head units with an axle.

Цель предлагаемого изобретени  - уменьшение нагрузок па стрелу. Дл  этого свободные концы стоек соединены носредством сферических шарниров с осью головных блоков, к средней части которой шарнирно прикреплены гибкие т ги.The purpose of the present invention is to reduce the loads on the boom. For this, the free ends of the posts are connected by means of spherical hinges with the axis of the head blocks, to the middle part of which flexible rods are hinged.

На чертеже представлено рабочее оборудование .The drawing shows the working equipment.

Рабочее оборудование содержит стрелу 1 со стойками 2, головиые блоки 3 с осью 4, сферические шарниры 5, гибкие т ги 6 и канатиую подвеску 7. Свободные концы стоек 2 посредством шарниров 5 соединены с осью 4; к средней части этой оси шарнирно нрикреплены т ги 6.The working equipment contains an arrow 1 with uprights 2, head blocks 3 with an axis 4, spherical hinges 5, flexible rods 6 and a rope suspension 7. The free ends of the uprights 2 are connected by means of hinges 5 to the axis 4; To the middle part of this axis are the hinges 6.

Благодар  тому, что стойки 2 стрелы непосредственно не соединены друг с другом, а ось 4 головных блоков установлена в сферических шарнирах, стойки могут перемеш,атьс  из плоскости стрелы независимо одна от другой , вследствие чего в подвеске и стреле неDue to the fact that the pillars 2 of the boom are not directly connected to each other, and the axis of the 4 head blocks is installed in spherical hinges, the pillars can be stirred, moving out of the plane of the boom independently of one another, as a result of which the suspension and the boom are not

будет перегрузок, св занных с различием в длинах ветвей подвески. Система стала статически определимой. При этом благодар  гибким иредварительно нат нутым элементам,there will be overloads associated with a difference in the lengths of the arms of the suspension. The system has become statically determinable. At the same time, thanks to flexible and pre-tensioned elements,

соедин ющим среднюю часть оси головных блоков с нижней частью стоек, создаетс  устойчивость и исключаетс  изгиб стоек в плоскости стрелы от боковых нагрузок. Изгибающий момент на оси в процессе копани  от гибких элементов не превышает 15% момента от подъемных канатов.connecting the middle part of the axis of the head blocks with the bottom of the uprights creates stability and eliminates the bending of the uprights in the plane of the boom from lateral loads. The bending moment on the axis in the process of digging from flexible elements does not exceed 15% of the moment from the hoisting ropes.
