Description
Известны шевровые подъемники дл монтажа , например, мостовых кранов, включающие ригель с шарнирными онорными стойками и грузовым полиспастом.Known hoist lifts for mounting, for example, bridge cranes, including a bolt with articulated axle struts and a cargo polyspast.
Предлагаемый шевровый подъемник отличаетс тем, что, с целью исключени действи горизонтальных сил на опорные конструкции, основани опорных стоек попарно соединены т гами, в средней части которых закреплена траверса, соединенна посредством троса с ригелем опорных стоек.The proposed elevator is distinguished by the fact that, in order to exclude the effect of horizontal forces on the supporting structures, the bases of the supporting posts are pairwise connected by means of treads, in the middle part of which a yoke is fixed, connected by means of a cable to the deadbolt of supporting posts.
Па фиг. 1 и 2 изображен предлагаемый подъемник.Pa figs. 1 and 2 shows the proposed lift.
Шевровый подъемник содержит онорные стойки 1 и грузоподъемный полиспаст 2. Башмаки 3 и 4 двух шарнирно соединенных оголовками стоек 1 установлены на монтажных опорах 5, жестко закрепленных на строительных конструкци х 6, и попарно св заны т гами 7, подвешепными тросом 8 через траверсу 9 к ригелю 10, образу замкнутые треугольные системы с внутренним распределением сил.The chevre elevator contains the on-pillars 1 and the hoisting polyspast 2. The shoes 3 and 4 of the two pivotally connected heads of the racks 1 are mounted on the mounting supports 5 rigidly fixed on the building structures 6 and connected in pairs 7 by means of a yoke 9 bolt 10, to form a closed triangular system with an internal distribution of forces.
при работе шеврового подъемника строительные конструкции будут воспринимать только вертикальные нагрузки, так как т ги 7 снимают со строительных конструкций горизонтальные нагрузки. Башмаками 3 одного из шевров снимают горизонтальные усили с опор при удлинении т г 7.when the chevreva hoist is in operation, building structures will perceive only vertical loads, as the cables 7 remove horizontal loads from building structures. Slippers 3 one of the chevres relieve horizontal forces from the supports when lengthening t g 7.
