Description

Изобретение относитс к промышпенному транспорту, в частности к телескопическим захватам стеллажных кранов - штабелеров.The invention relates to industrial transport, in particular, to telescopic grips of rack cranes.

Известен телескопический захват, содержащий основание и смонтированные на нем подвижные среднюю и верхнюю грузонесущую секцщ, направл ющие , расположенные на средней секции, и контактирующие с ними катки, за:крепленные на основании и верхней секции.A telescopic gripper is known, comprising a base and movable middle and upper load carrying section mounted on it, guides located on the middle section, and rollers in contact with them, behind: mounted on the base and top section.

В известном захвате средн и верхн секции перемещаютс по каткам , установленным на запрессованных в металлоконструкций секций консольных ос х 1 .In the known grip, the middle and upper sections are moved along rollers mounted on cantilever axles 1 pressed into the metal structures of the sections.

Недостатке известного устройства вл етс то, что нагрузки от веса при выдвинутом захвате воспринимаютс в основном двум Крайними катками , что снижает их надежность и долговечность и увеличивает износ как наМравл ющих,так и самих катков.The disadvantage of the known device is that the loads from the weight with the extended grip are perceived mainly by two Extreme rollers, which reduces their reliability and durability and increases the wear of both the Impact rollers and the rollers themselves.

Цель изобретени - повышение надежности и долговечности катков.The purpose of the invention is to increase the reliability and durability of the rollers.

Поставленна цель достигаетс тем, что телескопический захват снаб-: жен щарнирно прикрепленньми к основанию и верхней секции балансирами, при этом одни концы осей каждой пары прикреплены к каждому балансиру, а в основании и в верхней секции выполнены отверсти дл размещени в The goal is achieved by the fact that the telescopic grip is equipped with: hingedly attached to the base and upper section by balancers, with one ends of the axes of each pair attached to each balancer, and at the base and in the upper section holes are made for

10 них с зазором других концов упом нутых осей.10 of them with a gap of the other ends of the mentioned axes.

Claims

20 forklift crane stacker not shown). On axis 2, fixed in base 1, and fixed on top section 3 of axis 4, hinge3-9, two-shaft balancers 5 and 6 are mounted, in which rollers 11-14 are mounted on axis X7-10 on bearing X. Moreover, the axis 7-10 are made elongated. The rollers 13 and 14 move along the middle section 15, and that, in turn, moves along the rollers 11 and 12. The free ends of the axes 7 and 8 enter with a gap in the holes 16 and 17 of the base I, and the free ends of the axes 9 and 10 enter with a gap in the holes 18 and 19 of the upper load-carrying section 3, the size of the gap allows you to adjust the angle of rotation of the balancers 5 and 6. The double-wing balancers 5 and 6 from horizontal movement on axes 2 and 4 are held by pins 20, which axis 2 and 4 are supplied with rings th irochku. Axes 7-10 are kept from horizontal movement by washers 21. The telescopic gripping movement is carried out by a drive (not shown) which is connected via a coupling to shaft 22. Gear 23 is mounted on shaft 22, which interacts with gears 24 and 25, which,. in turn, interact with the rail 26 mounted on the middle section 15. On the middle section 15 ycTaHOBj na gear 27, interconnecting with sixteen wheels 28 and 29, which are also mounted on the secondary section 15, Gears 28 and 29 interact with the rails 30 fixed on bases x 1 and 31 are set When the grip is extended, the cantilever loads from the load are perceived uniformly by the rollers 11, 12 and 13, 14, since when the axes of the sliding sections deviate from the horizontal axis, the rollers 11-14 copy the surface of the guide center section, thus ensuring constant contact of the rollers P-14 with the guides and, as a result, uniform load distribution. The grip works as follows. When the drive is switched on (not shown using rack-and-pinion gear, sections 3 and 15 are pushed inside the rack (not shown) and when lifting the forklift of the stacker crane with the catch, the upper section removes the load from the rack, after which the sections are moved to the original position with load. When the upper section 3 and the middle section 15 return to their initial position, the rollers 11-14 freely enter the guides of the middle section 15, since the rotation of the double fork balances 5 and 6 is limited by the gaps between axes 7-10 and 16-19. Use of the invention provides an increase in the reliability and durability of the rollers and a decrease in the wear of the guides. The economic effect in the national economy of a single automatic racking crane g / p 1, i.e., which uses the proposed grip, is 20,000 rubles. Formula of the invention. A telescopic grip containing a base and movable middle and upper load-carrying sections mounted on it, guides located on the middle section, and rollers in contact with them fixed on The upper section is also characterized in that, in order to increase reliability and durability, it is equipped with balancers hinged to the base and upper section, with one ends, axes of each pair of rollers attached to each balancer, and at the base and in the upper section holes are made to accommodate the other ends of said axes with a gap.
