Description

(54) ГРУЗОЗАХВАТНОЕ УСТРОЙСТВО(54) CARGO HANDLING DEVICE

Изобретение относитс к подъемнотранспортному машиностроению, в частности к грузозахватным устройствам дл кранов.The invention relates to a lifting transport machinery, in particular to lifting devices for cranes.

Известно грузозахватное устройство , содержащее несущую балку, установленные На ней с возможностью перемещени распределительные блоки, снабженные грузозахватными органами, и грузовой канат, огибающий блоки и снабженный регул тором нат жени A load gripping device is known, comprising a carrier beam mounted on it with the possibility of moving distribution blocks, equipped with load gripping bodies, and a load rope, which goes around the blocks and is equipped with a tension regulator

Однако это устройство не имеет возможности регулировани рассто ни между захватными органами в различных направлени х.However, this device does not have the ability to adjust the distance between the gripping bodies in different directions.

Наиболее близким к изобретению по технической сущности вл етс грузозахватное устройство, содержащее траверсу, снабженную скобами дл наве йивани ее на крюк крана, установленные на траверсе с возможностью перемещени вдоль нее захватные органы и приводной механизм регулировани рассто ни между захватными органами С23 .Closest to the invention by technical essence is a load gripping device comprising a traverse equipped with brackets for directing it onto a crane hook, mounted on the traverse with the possibility of moving along it the gripping bodies and the drive mechanism for adjusting the distance between the gripping bodies C23.

Однако это устройство характеризуетс невозможностью изменени рассто ни между захватными органами в поперечном направлении, что сужает .сферу его применени .However, this device is characterized by the impossibility of changing the distance between the gripping bodies in the transverse direction, which narrows its scope.

Цель изобретени - расширение эксплуатационных возможностей.The purpose of the invention is the expansion of operational capabilities.

Поставленна цель достигаетс тем, что в грузозахватном устройстве траверса выполнена в виде параллелограмма , противоположные стороны которого попарно соединены группой перекрещивающихс планок с прорез ми, The goal is achieved by the fact that in the load gripping device the traverse is made in the form of a parallelogram, the opposite sides of which are connected in pairs by a group of intersecting slats with slots

10 в которых установлены захватные органы , а на каждой стороне параллелограмма выполнен паз, в котором установлен ползун, соединенный посредством т ги с крайней планкой, причем соседние планки соединены между со15 бой промежуточными т гами и на каждой стороне параллелограмма установлен механизм регулировани рассто ни между захватными органами, включающий в себ зубчатое колесо и рей20 ку.10 in which the gripping bodies are installed, and on each side of the parallelogram there is a groove in which a slider is installed, connected by means of a pull to the extreme bar, and the adjacent strips are connected between so-called intermediate links and on each side of the parallelogram there is a mechanism for adjusting the distance between the gripping bodies, including a gear wheel and rei20 ku.

На фиг.1 изображено устройство, вид спереди; на фиг.2 - разрез А-А на фиг.1 на фиг.З - разрез Б-Б на фиг.2.Figure 1 shows the device, front view; figure 2 - section aa in figure 1 in fig.Z - section bb in figure 2.

25 Устройство содержит скобы 1 дл подвески к крану, закрепленные на параллелограммной траверсе 2, стороны которой вл ютс направл ющими дл перемещени по ним соединенных25 The device contains brackets 1 for hanging up to a crane, mounted on a parallelogram traverse 2, the sides of which are guides for moving along them connected

Claims

30 with each other additional tami 3 crossing planks 4, having grooves 5, in which the gripping bodies are installed. B. On the traverse, there is a mechanism for adjusting the suspension pitch of the gripping organs, having half shafts 7 moving the markers 8 along the guiding tongs 9 traverses by means of 10 gears 11 fixed in them on the axes, which engage with the rails 12 of the traverse connected by straps 13 with proximal strips, with the distant strips attached to the traverse with screws 14 The device operates as follows. Traverse 2 is attached by brackets 1 to the crane. After that, the gripping bodies b pick up the cargo and transport it to the place of unloading, where the suspension step of the gripping bodies is changed and the cargo is loaded for further technological operation. The change in pitch is due to the rotation of the gears 11 by the flywheels 8. The gears cause a constant movement of 13 and 13, which, depending on the direction of rotation of the gears of the 11, reduce or separate the crossing bars 4. From 13 the movement is transmitted through the bars 4 to the gripping organs b. When breeding strips 4, each of them moves the gripping organs along its grooves 5 until it reaches the desired step. During the reverse rotation of the gears 11, the gripping bodies b converge between themselves under the action of moving the slats 4. The invention allows to expand the operating capabilities of the gripping device due to the additional movement of the gripping bodies across the crosshead, thereby combining several lifting devices into one, simplifying ease of maintenance, and increase labor productivity 2.3 times. Claim device containing a traverse, provided with brackets for hanging it on a crane hook, mounted on the traverse with the possibility of moving along it the gripping bodies and the driving mechanism for adjusting the distance between the gripping bodies, characterized in that in order to enhance operational capabilities, the traverse is made in the form of a parallelogram, the opposite sides of which are pairwise connected by a group of intersecting slats with slots in which the gripping bodies are installed, and Each side of the parallelogram has a groove in which a slider is mounted, connected by means of a pull to an extreme bar, with the folding bars interconnected by intermediate straps and on each side of the parallelogram there is a mechanism for adjusting the distance between the gripping bodies, including a gear wheel and a rail.
