Description
Изобретение представл ет собой усовершенствованно механизма изменени вылета в кранах с шарннрно-сочлененными стрелами.The invention provides an improved mechanism for varying overhang in cranes with articulated booms.
Известны уже нодобного рода механизмы , заключающне в себе два нриводных соосных зубчатых сектора-кривошипа, св занных т гами со стрелой и рычагом противовеса крана. Ввиду неравномерного распределени нагрузки между т гами, имеет место перегрузка приводного вала механизма.Known mechanisms of the same kind are already known, consisting of two coaxial axle gears, which are connected by means of a boom and a crane counterweight lever. Due to the uneven distribution of the load between the rods, there is an overload of the drive shaft of the mechanism.
Отличительной особенностью механизма изменени , вылета крана с шарнирносочлененной стрело11 но изобретению в .г етс то, что т ги присоединены к рычагу противовеса цри иомощи балансиров.A distinctive feature of the mechanism of change, the crane's departure from the articulated arrow of the invention is the fact that the rods are attached to the lever of the counterweight to the help of balancers.
Применение балансирного соединени между exaнизмoм изменени вылета стрелы и соедин емыми с ним стрелой и иротивовесом обесиечивает равномерное расиределенно нагрузок между секторамикривошипами п надежность действи механизма и в том числе его приводного вала.The use of a balance joint between the boom lift change and the boom and the counterweight connected to it ensures a uniform distribution of loads between the sectors of the crank and the reliability of the mechanism, including its drive shaft.
На чертеже изображена обща схема механизма.The drawing shows a general scheme of the mechanism.
Зубчатые секторы-кривошины (1) механизма изменени вылета стрелы св заны т гами (2) с балансиром (3) стрелы и т гами (20 с балансиром (3) противовеса (4).The gear sectors of the crankshaft (1) of the mechanism for changing the boom reach are connected by t-rods (2) to the balance bar (3) of the boom and drags (20 to the balancing bar (3) of the counterweight (4).
Иредмет изобретени Iredmet invention
Механизм изменени вылета в кранах с Бирнирно-сочлененной стрелой, заключающий в себе два ириводных соосных зубчатых сектора-кривошипа, св занных т гами со стрелой и рычагом противовеса крана, о т л и ч а ю щ и и с тем, что, с целью равномерного расиределени нагрузки между секторами-кривошипами, т ги присоединены к стреле и рычагу противовеса нри иомощи балансиров.The mechanism for changing the overhang in cranes with a Birnier-articulated boom, comprising two coaxial irivial coaxial toothed crank sectors, connected with the boom and the counterweight lever of the crane, so that equal load distribution between crank sectors, ti gi are attached to the boom and the counterweight lever on balance balances.
