(54) AUTOMATIC TICK-UP CAPTURES FOR PIECE CARGOES

I

FIELD OF THE INVENTION The invention relates to lifting and transporting equipment, in particular, to tong-borne grips for piece goods.

An automatic tick grip for piece goods, containing castors, one ends of which are connected by means of t with an axle of an earring attached to a hook of a lifting machine, and a fixing mechanism for casting glands in an open position, including a vertical stand with a longitudinal groove and a ratchet wheel fixed on the axis of the earring, interacting with the spring-loaded dog I.

However, the known device is not sufficiently reliable in operation, since it does not fix the axis of the shackle in all its positions. .

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that the fixation mechanism is equipped with a slider mounted on a rack and attached to an earring on which the said spring-loaded doggie is hinged, an additional doggie that is hinged on the earring and also interacting with the ratchet wheel, and a counterweight attached to the earring, This axis of the earring is located in the figure, the groove of the stand and is made with two parallel flat surfaces.

FIG. 1 shows the capture, general view; in fig. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. 2; in fig. 4 - section BB

 in FIG. 3

The gripper contains castors 1 and 2 with matching jaws 3, one ends of which are connected by means of tg 4 to the axis 5 of the shackle 6 attached to the hook of the lifting machine. The other ends of the castors 1 are pivotally mounted on the yoke 7. The grip is equipped with a fixing mechanism for the castors in the extended position, including a vertical stand 8 with a longitudinal shaped groove 9 consisting of two cheeks and a ratchet wheel 10 mounted on the axis 5 of the earring 6. interacting with the spring-loaded dog 11. The spring-loaded dog 11 is hingedly mounted on the slider 12 mounted on the rack 8 in the guides 13 and attached to the shackle b. The fixation mechanism is also provided with an additional dog 14, hinged on the earring 6 and also interacting with the ratchet wheel, and a counterweight 15 mounted on the earring 6. The axis 5 of the earring b is made with two parallel flat surfaces and is located in the shaped groove 9 of the rack 8, the lower part of which has the shape of an incomplete circle. A support 16 is fixed on the post 8 to fix the horizontal position of the earring 6. The apertures 17 serve to adjust the grip to the size of the load.

Capture works as follows.

To fix the grip of the grip openings, it is necessary that the axis 5 of the earring 6 be in a position in which its parallel flat surfaces are located horizontally. In this position, the grip is placed on the cargo to be transported. After that, when lowering the hook of the lifting machine, the stud 6, under the action of the counterweight 15, rotates left to 90 ° until it stops 16. At this time, the pawl 14 slides along the teeth of the ratchet wheel 10, and the pawl 11 keeps the ratchet wheel from turning. When the earring 6 is subsequently lifted, the pawl 14 turns the ratchet wheel 10 at an angle of 90 °, and with it the axis 5. Now that axis 5 has turned 90 °, its parallel flat surfaces in the vertical position along the shaped groove 9 of the rack 8. Axis 5 rises up in the shaped groove 9 of the rack 8, moving the rods 4. These turn the castors 1 and 2 around their axes, clamping the loading weight. the release of the cargo is necessary to lower it on the floor plane. Continuing to lower the hook of the lifting machine down together with the earring b, the castors 1 and 2 open, and when the axis 5 of the earring b is lowered to the lower extreme position, it is in the lower part of the groove 9, which has the shape of an incomplete circle.

No

The shackle 6, under the action of the counterweight 15, rotates to the left through an angle of 90 °. After that, the earring is raised to a vertical position, while the dog 14 enters the hollows of the ratchet wheel 10 and moves it along with the axis through an angle of 90 ° and the parallel flat surfaces in the axis 5 occupy a horizontal position, fixing the castors 1 and 2 in the opened position.

After this, the capture operation cycle is repeated.

The invention improves

reliability of capture in work.
