Изобретение относитс к подъемно-транспортному оборудованию, а именно к захватным устройствам дл грузов.FIELD OF THE INVENTION The invention relates to lifting and handling equipment, namely, gripping devices for cargo.

Известно захватное устройство дл грузов , содержащее присоедин емую к грузоподъемному механизму раму, с которой посредством переходных элементов св заны изогнутые подхватные лапы 1.A cargo gripping device is known, comprising a frame attached to the lifting mechanism, with which the bent lifting legs 1 are connected by means of transition elements.

Недостатком данного устройства вл етс то, что захват и освобождение- грузов осуществл етс вручную.The disadvantage of this device is that the seizure and release of the goods is carried out manually.

Цель изобретени - автоматизаци процесса захвата и освобождени грузов.The purpose of the invention is to automate the process of seizure and release of cargo.

Указанна цель достигаетс тем, что кажда подхватна лапа снабжена механизмом фиксации ее положени , а переходные элементы выполнены в виде стоек с пазами в нижних част х, на концах которых щарнирно закреплены подхватные лапы, центральна часть каждой из подхватных лап оборудована шарнирной т гой, свободный конец которой снабжен обкатными роликами, установленными с возможностью перемещени в упо.м нутом пазу, при этом механизм фиксации положени подхватных лап содержит щарнирный подпружиненный крюк с пальцами , расположенный в пазу стойки, и щарнирно подпружиненную защелку св занную посредством гибкой св зи с т гой.This goal is achieved by the fact that each grasping paw is equipped with a mechanism for fixing its position, and the transition elements are made in the form of racks with grooves in the lower parts, at the ends of which the lifting legs are hinged, the central part of each of the lifting legs is equipped with a hinge thrust, free end which is provided with rolling rollers installed with the possibility of moving in an fitted m groove, while the mechanism for fixing the position of the gripping paws contains a hinged spring-loaded hook with fingers located in the groove at the rack, and a pivotally spring-loaded latch connected by means of a flexible connection with the pull.

Кроме того, с целью расщирени диапазона типоразмеров захватываемых грузов, рама выполнена раздвижной.In addition, in order to expand the range of sizes of the captured cargo, the frame is made sliding.

Концы подхватных лап снабжены катками . При этом угол между концами каждой изогнутой подхватной лапы больще 90°, но меньше 180°На фиг. 1 показано захватное устройство дл грузов, общий вид; на фиг. 2 - то же, вид сбоку; на фиг. 3 - стойка с подхватной лапой и механизмом фиксации ее положени ; на фиг. 4 - вид А на фиг. 3; на фиг. 5 - рама в сборе.The ends of the raised paws are provided with rollers. In this case, the angle between the ends of each curved grasping paw is greater than 90 ° but less than 180 °. In FIG. 1 shows a gripping device for cargo, a general view; in fig. 2 - the same, side view; in fig. 3 - stand with a catch foot and a mechanism for fixing its position; in fig. 4 is a view A of FIG. 3; in fig. 5 - frame assembly.

Claims

The device comprises a sliding frame 1 comprising two hollow beams 2, having slings 3 and fastened by a connecting beam 4, in the center of which are brackets 5. Between the hollow beams 2 are installed two sliding beams 6 which are alternating relative to each other. on which slats 8 are fixed, moving relative to each other by means of an indicator wheel 9 dimensions of the load, having a brush 10 mounted on the shaft 11 passing through the beam 6. At the lower end of each rack 7 is pivoted and 12, provided with rollers 13. To the pickup paw 12 in its central part, there is a hinged 14 ha, the upper end of which is made in the form of a fork 15 with an axis 16 having rolling rollers 17. At the bottom of each rack 7 there is a groove 18 in which there is a mechanism for fixing the position of the paw 12, which includes a hinged hook 19 for an axis of 16 ti 14, spring-loaded 20, on the side surface of which a finger 21 is rigidly fixed, and a hinged latch 22 for fingers 21 of hook 19, spring-loaded 23. In this case, latch 22 st by means of a flexible connection 24 with t goy 14, which rollers 17 are mounted scheni possible changes in the groove 18 of each arm 7. The device operates as follows. The frame 1 with the paws 12 lowered down by means of the slings 3 is visited on the hook of the lifting mechanism and lowered onto the load so that the load is between the pillars 7 of the frame 1. At the same time, the rollers 13, slipping around the platform, allow each pair of paws 12 to extend towards each other and grip cargo. Due to the movement of the paws 12, the upper ends of the tg 14 by means of the rollers 17 move in the grooves 18 of the uprights 7, touch the hooks 19 and, overcoming the resistance of the springs 20, rotate the hooks 19 in the direction of the latches 22 until the forks 16 of the forks 15t g 14 do not they engage with the hooks 19. As a result of this engagement, the horizontal working position of the legs 12 is fixed, while the legs of the device 7 do not touch the platform. Then the device with the load is lifted and moved. To release the load, the device is lowered all the way down the stands 7 into the platform. As a result, the free ends of the paws 12, together with the hinged pins 14, are moved upwards and the last axles 16 turn the hooks 19 towards the latches 22 until the fingers 21 of the hooks 19 fall into the latches 22. The ends of the tg 14, and therefore and legs 12 are thus freed. After that, the device is lifted upward, the paws 12 slide downward under the action of its weight, and the flexible couplings 24 pull through the glands 14, which pull down the latches 22, the latter release the fingers 21 of the hooks 19, and the hooks 19 return to their original position. The device is changed over to other dimensions of the load by rotating the wheel 9 in one direction or another, which drives the gear 10 and the corresponding slats 8 associated with it. As a result, the pillars 7 are mounted on the required dimensions of the load to be captured. Claim 1. Grabbing device for cargo, containing a frame attached to the lifting mechanism, with which the transitional elements are connected and bent lifting legs, characterized in that, in order to ensure the automation of the process of seizure and release of cargo, each hog is equipped with a fixing mechanism the positions, and the transition elements are made in the form of racks with grooves in the lower parts, at the ends of which the catch legs are hinged, the central part of each of the catch legs is equipped and a hinged pull, the free end of which is provided with rolling rollers mounted for movement in said slot, wherein the locking mechanism of the lifting legs comprises a hinged spring-loaded hook with the fingers located in the notch of the stand and a hinged latch connected by means of a flexible link with m

2. The gripping device according to claim I, characterized in that, in order to expand the bottom of the range of the sizes of the loads to be taken, the frame is made sliding.

3. The gripping device according to claim 1, characterized in that the ends of the catch legs are provided with rollers.

4. The gripping device according to claim I, characterized in that the angle between the ends of each curved lifting foot is more than 90 °, but less than 180 °.
