Description

The invention relates to tick-borne grips with a device for automatically closing them on a load and for keeping them in an opened state after releasing them from the load. In the proposed gripper gripper, as well as in the existing grippers of this kind, there is an element for suspending the gripper on a lifting device hook and a frame carrying ticks on itself, which can be moved vertically relative to the suspension element and keeps the gripper in an opened state by means of a hook mounted on the suspension grip element to the lifting device.

. The peculiarity of the proposed tick grip is that to release the frame from the hook mounted on the suspension element when lowering the grip onto the load, a special core is used, which during this lowering abuts the load and moves upwards relative to the frame, freeing it from the curtain.

Thus, a tick-borne gripper without a load is always kept open, and after lowering the load it automatically opens again.

In FIG. 1 shows a general view of the total tick capture; FIG. 2 - the VID of his B plan, in a section on pAAA of FIG. one; FIG. 3 is a section along BB of FIG. one; FIG. 4 and 5 are two projections of a hook for picking up a frame carrying glue joints.

Tick-borne grip includes sponges 1, fixed at the ends of the crank levers 6, hingedly connected to the rods 5, having a common axis 4, passed through the holes of the grommet 2, on which the whole tick grip is highlighted on the hook of the lifting device.

The tongs levers 6 are also hingedly connected by pins 23, 24 to the cross member 22, consisting of two slats, connected by bolts 25. The slats comprising the cross member are provided with a series of holes for the bolts 25, allowing the extension of the cross member. At the same time, the jaws i with the help of bolts 26 can be mounted at an angle to the vertical processes of the levers 6.

Thanks to such a device, a tong-and-hold tackle can be set to any desired amount of cargo that needs to be lifted, while the jaws 1 are vertical.

The hinge axis 4, t g 5, passes through the vertical rails of the two lateral blades of the frame 3, which are interconnected by spacer bolts 7, 8 and ginks 27, 28 welded from the sides.

To the bottom of them, strips 28 are welded perpendicularly through them to the cheeks 29, covered by bolts 25 with rails of the cross member 22. Thus, the cross member 22 with the hinges 23, 24 of the levers 6 is one of the same with frame 3.

Inside frame 3 there is located a core 18, having the form of a frame, formed from two vertical lateral planks with longitudinal grooves connected by an axle strut 20 from above and welded to the bottom transverse bar 30 at the bottom. The frames 3, put on the spacer bolts 7 and 8, on the spacer-bolt 7 of the frame 3 are also fitted with a sleeve 10, and an axis 19 on the axis 20 of the core 18.

On axis 4, connected with the eye 2 for suspending the gripper on the lifting device, hook II (fig. 1, 2, 4, 5) is suspended inside the eyelet 2, having a stop 14 in a special slot 12 suspended on axis 13, in which the top edge, 3ajHHMaeT horizontal position, and the attachment to it and the knot of the cam 16 rests on the lower beveled edge of the notch 12. Thus, the stop 14 can deviate on its axis in the hook 11 only counterclockwise. Hook 11 itself has a stubborn strap 17 that prevents its deviation; io Pairav; to the genius of the hour hand.

The cycle of action of the tick capture consists of four operations:

The first of these is in the message to the pickup device of the open state. For this, the tong-and-hold clamp is suspended by the eyelet 2 and the lifting hook in such a way that the jaws 1 are in a reconstructed state, which is achieved by inserting a hook 11 and an iodine sleeve 10 of the upper cross member 7 of the frame 3.

The second operation is to lower the grip onto the lifted load.

When the gripping device is open, the heart, the jig 18 is in the position depicted by the dotted line (Fig.). In this state, the grab is lowered onto the object being lifted. When the core 18, which is in the lower position, reaches the surface of the raised Metric, it stops, while the other parts of the gripping device will continue to move down under their own weight. At the same time, the blade 16 of the anvil 14 of the hook 11 meets with the sleeve 19 of the core 18 and, sk; 1in in, causes the hook 11 to deflect to the right and exit from under the sleeve 10 of the frame 3. The frame 3 is released and falls together with the cross 22 on the load, so that vt.chka 10 is below the hook. At this time, the further OriycKai-e than eyelet 2 stops.

The deviation of the hook 11 to the right continues only as long as the stop 14 does not descend from the end of its short arm 15 from the sleeve 19. As the core 18 is stationary at this time, the shoulder 15 has time to lower slightly below the sleeve 19.

As a consequence, the stop 14 is released, and the hook 11 is returned, but now it meets Wtu, 1k10 with its inclined surface 21. This is followed by a third operation - seizing and lifting the load.

Since the hook 11 is now disengaged from the sleeve 10 and, therefore, from the frame 3, the axis 4 can now rise relative to the frame 3, which causes the jaws 1 and the gripper and the load to move closer through the arms 5 and 6. In this case, the shoulder 15 of the anvil 14 is deflected by the sleeve 19 slightly down and jumps over it, allowing Hook 11 to lift and slide. With its surface 21 along the sleeve 10, press down the vertical position and, lifting the screw: cu 19, lift the core 18. In this form, the grip of the clamp with the clamped jaws 1 load is lifted by the lifting device upwards and carries the load Pa to the desired mcssto.

The last operation consists of lowering the transported cargo and its release from the tick-borne capture.

When the load is lowered into place, the hook of the Lifting device with eye 2 must be lowered further. In this case, the axis 4 under the action of the hook 11 and other parts of the device will continue to be released downwards, and the hook 11 with its lower inclined surface 21 meets with the sleeve 10, which is seated on the axis 7 of the frame 3, and due to further lowering is deflected right. When surface 21 comes off the ilO bushing, the hook fits back under the action of its own weight. At this point, the lowering of the lifting hook should stop. When switched on after that, on lifting, the hook 11 picks up the sleeve 10, and with it the entire gripping device in the opened state.

The subject matter of the invention.
