(54) ЗАХВАТНОЕ УСТРОЙСТВО ДЛЯ ГРУЗОВ С ОТВЕРСТИЕМ(54) CAPTURE DEVICE FOR CARGOES WITH OPENING

1one

Изобретение относитс к грузозахват ным устройствам, предназначенным, в частности , дл перегрузок грузов, снабженных специальными отверсти ми с буртиком.The invention relates to load gripping devices intended, in particular, for transshipment of goods, provided with special openings with a collar.

Известно захватное устройство дл грузов с отверстием, содержащее корпус, установленные на нем кулачки с рифленой поверхностью и распорное приспособление дл кулачков 1.Known gripping device for goods with a hole, containing the body, mounted on it cams with a corrugated surface and spacer device for cams 1.

Однако это устройство не обеспечивает безопасного выполнени операций, так как сцепление с грузом обеспечиваетс лишь за счет трени .However, this device does not provide safe performance of operations, as the coupling with the load is provided only by friction.

Наиболее близким к изобретению по технической сущности вл етс захватное устройство дл грузов с отверстием, содержащее корпус, шарнирно закрепленные на нем захватные рычаги с опорными поверхност ми на их верхних концах, и приспособление дл фиксации положени рычагов 2. Closest to the invention, in technical terms, is a gripping device for loads with a hole, comprising a housing, gripping levers hinged on it with supporting surfaces at their upper ends, and a device for fixing the position of the levers 2.

Недостатком этого устройства вл етс сложность конструкции из-за наличи механизма фиксации, содержащего систему рычагов и подпружиненных защелок.A disadvantage of this device is the complexity of the design due to the presence of a locking mechanism containing a system of levers and spring loaded latches.

Целью изобретени вл етс упрощение конструкции.The aim of the invention is to simplify the design.

Поставленна цель достигаетс тем, что корпус выполнен конусной формы с углублением в основании и пазами в боковой поверхности, в которых расположены рычаги , а приспособление дл фиксации положени рычагов выполнено в виде магнитных защелок.The goal is achieved by the fact that the body is made conical with a recess at the base and grooves in the side surface in which the levers are located, and the device for fixing the position of the levers is made in the form of magnetic latches.

При этом приспособление дл фиксации положени рычагов может быть выполнено в виде закрепленных на корпусе пластинчатых пружин.In this case, the device for fixing the position of the levers can be made in the form of plate springs attached to the housing.

На фиг. 1 показано устройство, разto рез; на фиг. 2 - выполнение приспособлени дл фиксации положени рычагов в виде пластинчатых пружин.FIG. 1 shows the device, the cut; in fig. 2 shows a device for fixing the position of the levers in the form of plate springs.

Claims

The gripping device consists of a conical shaped body 1: on which 15 hinges 2 secure the gripping levers 3 with the shanks 4. In the upper part, the body 1 ends with a ring 5 to which the hook of the load-lifting mechanism is attached, and in the middle part of the body of the body are installed for each rotary lever magnetic latches 6 for keeping the levers in the closed state when the gripping device is withdrawn from the socket. A hole 7 is made in the center of the base of the case for orienting the device in the socket with the help of a pin 88. The proposed device is used for lifting a load equipped with a hole in the form of a cylinder 9, having in the upper part a support shoulder 10, and in the lower part a conical bottom 11 with a vertex up. The top ends with a pin 12. Magnetic latches can be made in the form of plate springs 13 (Fig. 2). The device works as follows: a device with levers diluted under the influence of the property of the force m, goes into the cylinder 9. As soon as; аги; the chugs pass the supporting collar 10 and from (syunts to the contact of the inner wall of the cylinder), the load will be seized. After transferring the load, to remove the device from the cylinder 9, its lifting mechanism is preliminarily lowered until the shanks of the 4 gripping levers 3 are seated on the tapered bottom of the slot; the gripping levers 3 are closed and fixed by the latches 6. The lifting device is lifted by a lifting mechanism d from the cylinder 9 and at the moment of the passage of the opening of the support collar 10, the gripping arms 3 are again opened by means of the shanks 4. Such an embodiment of the device allows simplifying its design and facilitating the process of attaching and lifting the load. Formula 1. Load gripper with a hole comprising a housing, gripping levers hinged on it with bearing surfaces at their upper ends and a device for fixing the position of the levers, characterized in that, in order to simplify the design, the housing is made Onus forms with a recess at the base and grooves in the side surface in which the levers are located, and the device for fixing the position of the levers is made in the form of magnetic latches 2. The device according to claim I, characterized in that the device for fixing the position of the levers is made in the form of case of leaf springs Sources of information taken into account during the examination 1.
