Description

The invention relates to a subframe) transport equipment, namely to the mechanisms for fixing the gripping organ.

The purpose of the invention is to increase the convenience in the operation of the operation of exculpatory operations.

FIG. 1 shows the node attachment device, the general view; in fig. 2 - scan zigzag groove of the vertical cylinder; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. 3; pas figs. 5 is a diagram of the movement of the projections of the cup into the groove of the cylinder.

The mechanism of fixation of the gripping organ is mounted on the gripping device, which consists of a supporting structure (frame) on which the gripping organs are mounted - levers 2, pivotally connected to the lower ends of t g 3, and the upper ends of t g 3 P1 pivotally connected to a movable trap —because 4, which is connected to the hinge element on the load-lifting machine 5. Non-sup1. a coping 1 is placed on the load 6 to be lifted. The case 7 is rigidly attached to the supporting structure 1, and the rod 8 to the traverse 4.

The cavity of the housing 7 is closed from the bottom by a flange 9. To which a vertical cylinder 10 is attached, on the side surface of which the sectional section is zigzag-shaped, with vertical sections 11 in the zone ei o Bcpninu.

FIG. 2 shows that at the end of the rod 8 is vcTaHoii. ien cup 12, pressed against the player's rojiOBi ce by 8 nuts 13 and 14 through a non-rigid spring 15, which prevents the 12 from turning 12 relative to niTOKa 8.

The nut 16, screwed onto the body 7, limits the vertical movement of the cup 12 inside the body 7 in the units h. The glass 12 is provided with three protrusions 17, which are inserted into the groove of the cyo-string I).

The device works as follows;

Nesupiz konsgruktsi (pa.ma) 1 is set to the load 6. When the yoke 4 rises to a height h, the levers 2, loosening, grab the load (in Fig. 1, the lines are shown).

Under the lifting of the traverse 4 to the height h, I can capture the load, it is possible if HiTOK 8 leaves the corus 7 in the axial direction. If the cylinder interferes with this axial movement, the gripping device rises with the gripping arms 2 fixed in the opened state. Coal and frame 1 are supported on load 6, the load rope 18 is loosened. The node is driven by the weight of the crosshead 4, the levers 2, tg 3 and the rod 8, the latter together with the cup 12 is lowered, and the protrusions 17 of the cup enter the vertical sections 11 of the groove of the cylinder 10, which is adjusted beforehand during assembly. The protrusions 17, lowering downward, slide along the inclined surfaces of the groove all the way into the top of the tongue groove, causing the cup 12 to rotate relative to the rod 8. As can be seen in FIG. 4, lifting the rope 18 will cause the protrusions 17 not to be displaced all the way into the upper hollow of the groove.

In this case, the protrusions 17 also slide along the sloping portions of the groove of the cylinder 10. Make the cup 12 rotate relative to the rod 8 in the same direction as before, and eventually the cup 12 will rotate relative to the rod 8 to 1/6 of the circumference. Further lifting of the cargo rope 18 causes the lifting of the gripping device with the open levers 2.

In this position, the gripping device is prepared for constant, cyclical operation.

Next, the device is lowered onto the load 6 until the capat 18 is loosened. Under the action of the weight of the crosshead 4, t g 3, the levers 2 and the H1 current 8, the projections 17 of the cup 12 from the upper cavities of the groove are lowered down to the stop in the after. 1st lower hollow. Then lift the gripping device. The protrusions 17 of the cup 12, lifting up and interacting with the slots of the cylinder 10, make the staples 12 even 1/6 of the circumference around the axis of the inTOKa 8 and, after passing through the vertical section of the groove, allow the rod 8 to make the path h from the support of the housing 7. This raises the yoke 4 and the gi 3 relative to the frame 1, and the levers 2 rotate to capture the load 6, which is then moved by the gripper to the desired location.

In order to free the gripper from the load, it is necessary to add the last hmo / gavel to the gtabel with the weakening of the hoop rope. In this case, the yoke 4, ti g. ;

frame I. At the same time, the 17 W. VOLUME ()

in the vertical sections to unor. turning while stakap 12. Pos; food-lifting of the load rope will cause the protrusions 17 to rise into the upper hollow of the groove. In this case, an 8 meter can make strokes of magnitude h, since it will be rigidly connected with the frame. Dal1) Ney. A cargo rope will cause a full gripping device with open points 1. 2.

After that, the cycle of capturing and releasing the gripping device from the load is repeated.

If necessary, raise the co-stepper with .m ruzom. (Brick) 4acTJ 4 io to unload it on the pa.ap area, you should take the final unloading on the second or

third and so on The vertical sections of the groove of the cylinder 10 are made at least over two adjacent vertices of the zigzag groove.

This will allow another loading of the load (container), followed by the lifting of the gripping device with the gripping levers open.
