Изобретение относитс к подъемно-транспортному оборудованию.This invention relates to a lifting and transport equipment.

Известно захватное устройство, содержащее штангу, св занную при помощи петли с грузоподъемным механизмом, ползун, установленный на штанге, закрепленную на ползуне траверсу, захватные рычаги, шарнирно-закрепленные на траверсе, и шариковый стопорный механизм 1A gripping device is known comprising a rod connected by a loop with a lifting mechanism, a slider mounted on the rod, mounted on the slider to the yoke, gripping levers hinged to the traverse, and a ball stop mechanism 1

Однако такое устройство ненадежно в работе .However, such a device is unreliable in operation.

Цель изобретени - повышение надежности устройства в работе.The purpose of the invention is to increase the reliability of the device in operation.

Это достигаетс тем, что оно снабжено дополнительной подпружиненной траверсой, установленной на штанге, а основна траверса закреплена на ползуне с возможностью перемещени относительно него и снабжена шариковым фиксатором ее положени , при этом между траверсами расположена пружина. Кроме того, шариковый стопорный механизм- содержит обойму с кольцевой проточкой, установленную на ползуне с возможностью перемещени и снабженную шариковым фиксатором ее положени относительно ползуна, а шариковыеThis is achieved by the fact that it is provided with an additional spring-loaded cross-member mounted on the rod, and the main cross-arm is fixed on the slide with the possibility of movement relative to it and is equipped with a ball-lock for its position, while there is a spring between the cross-bars. In addition, the ball locking mechanism contains a holder with an annular groove mounted on the slide with the possibility of movement and equipped with a ball lock its position relative to the slide, and the ball

На фиг. 1 изображено захватное устройство, общий вид в исходном положении; на фиг. 2 то же, в момент захвата груза; на фиг. 3 то же, в момент освобождени груза; на фиг. 4 - шариковый фиксатор.FIG. 1 shows a gripping device, a general view in the initial position; in fig. 2 the same, at the time of seizure of cargo; in fig. 3 the same at the time of release of the goods; in fig. 4 - ball retainer.

Claims

The device includes a rod 1, on which an anvil ring 2 and prismatic plugs 3 and 4 are mounted. In the middle part of the rod 1 there is an annular groove 5. On the rod 1 it is mounted with the help of a key 3 in the axial direction of the slider 6 with six radial holes arranged around the circumference to accommodate the locking balls 7. On the slider 6 there is a restrictive ring 8 and a yoke 9 moving along the key 10. The traverse 9 has a cup-shaped base 11 with brackets 12 and sleeve 1 welded to it 3. In the upper part of the rod 1 on the key 4, preloaded with spring 14, an additional traverse 15 is installed, similar in construction to traverse 9, and a supporting washer 16. The ring 17 and the lifting lug 18 are fixed on the rod 1 with a pin. A washer 19 and a limiting ring 20, fastened with a pin, are installed in the lower part of the rod 1. On the upper part of the slider 6, the holder 21 with an annular groove 22 is worn. a spring 26 balls 27 entering the corresponding lazy corner on a slider 6 and a holder 21. A pin 28 serves to limit the movement of the balls 27. A spring 29 is installed between the crossbars 9 and 15. The bracket 12 of the crosspiece 15 is connected by hinged links 30 with gripping levers 31. Bracket 12 traverse 9 also ball irno associated with the gripping levers 31 whose lower ends are pivotally connected to the legs 32. The force of the compression spring 14 over the compression force of the spring 29 and the spring retainer 23, the compression force greater compressive force pruzhnny retainer 24. The gripping device operates as follows. In the initial position of the yoke 9, the przokina 29 is displaced to the lower extreme position to the anvil ring 8 and rests with the slide 6 into the washer 19. The clamp 23 of the yoke 21 is fixed in the upper recess of the slide 6 The balls 7 are between the cylindrical part of the rod 1 and the ring groove 22 sleeves 21. The latch 24 of the yoke 9 is fixed in the lower recess of the slide 6 (see Fig. 1 The load is captured as follows. When the gripping device is launched over the load, the legs 32 rest against the load installation platform. The force through the legs 32, the gripping arms 31 of the lugs 32 given on the cross bar, the cross bar 9 and the pop 6 are moved along the bar 1 to coincide with the groove 5 radial holes with balls 7. The slider 6 stops at ring 2, and the yoke 21 - at the cross bar 15, as a result of which the yoke 21 is displaced relative to the slider 6 Balls 7 slide into the groove 5 of the rod 1 and overlap the yoke 21, the slider 6 will be locked relative to the rod 1. The cross member 9 and 15 with this, occupy the position shown in fig. 2. This position of the cross arms 9 and 15 corresponds to the horizontal position of the links 30 44 of the additional cross bar 15. The load is in the trapped state. The unloading of the gripping device is as follows. When paws 32 are pressed against the load installation platform, the paws 32 and gripping levers 31 are transmitted to the yoke 9. Traverse 9, compressing the spring 29 with its sleeve 13, displaces the yoke 21 upwards, which, compressing the spring 14, shifts the additional yoke 15 upward to align the ball 27 retainer 23 with a top notch. Thus, the groove 22 of the yoke 21 is aligned with the radial holes of the slider 6, when the paws 32 are depressed, the springs 14 and 29 open and the balls 7 exit from the groove 5 of the rod 1 into the annular groove 22 of the yoke 21. The slide 6 is moved from the cross bar 9 to the bottom the position before the bearing washer 16. The grippers release the load and are held in the diluted state by the spring 29. The proposed gripping device will significantly increase the reliability of operation, and its speed will allow it to be used in automatic lines. Claim 1. Grabbing device comprising a rod connected by a loop with a lifting mechanism, a slider mounted on a rod fixed on a crawl above the traverse, gripping levers hinged on the traverse, and a ball stop mechanism, characterized in that in order to increase reliability of operation, it is equipped with an additional spring-loaded traverse mounted on the rod, and the main traverse is fixed on the slide with the possibility of movement relative to it and equipped with a ball-lock Nor, with this, a spring is located between the cross-arms.

2. A device according to claim 1, characterized in that the ball locking mechanism comprises a holder with an annular groove mounted on a slider with a possibility of movement and equipped with a ball lock its position relative to the slider.

3. The device on Sh1. 1 and 2, characterized in that the ball clamps of the cross member and the yoke with respect to the slide are made in the form of a spring-loaded ball that fits into the corresponding depressions of the slide.
