SU397457A1 - CAPTURAL DEVICE FOR CARGOES WITH INTERNAL CAVITY - Google Patents

Description

one

The invention relates to load-lifting mechanisms, and Imeino to a gripping device for cargoes with an internal cavity.

According to the main author. St. No. 359223 a gripping device for cargoes with an internal cavity is known, which contains a hollow body with a clamp at the bottom and at the top, and rope suspensions carrying spring-wedge-shaped fists.

The device is equipped with a pivoting lever, mounted on an axis fixed in a bracket and connected to a cable suspension bracket 1MI and a flexible, remote suspension line.

However, known, x devices for distancing release from the load are necessary KjpaH, equipped with two (main and auxiliary) hooks.

The purpose and: goiter | retani is the remote removal of cargo using a single lifting mechanism.

This goal is achieved by the fact that an eccentric with a manhole is rigidly fixed on the bracket, and the rotary lever is equipped with a spring-loaded dog with a tongue, the device is suspended to the "Ryuk" (Lifting mechanism via an auxiliary hook with counterweights.

FIG. 1 shows the proposed device; in fig. 2 - the same, at the moment of lifting the product; in fig. 3 - the same, at the time of raspropovka gripping device.

The device contains a hollow body / with a wedge 2 attached to it on one side and, on the other hand, an ogolovnik 3. Ogolo, a miniature is connected with 4 fingers to a shackle 5. A tooth is strengthened on a finger.

In the lifting bracket 4 is rigidly attached to the eccentric 7 with the groove 8.

The pivot arm 9 is fastened to the finger 5, the axle 10 is fixed on the KOTopoiM l-sister, equipped with a spring-loaded dog 7 / with pin 12. The spring 13 is set on the axis 0, pressing the dog. To the lever 9 with the aid of the pin 14 there are attached cable suspensions 15, on the ends of which Cams 16 are interrupted. Between the end faces of the cams and the diaphragm 17 located inside the case, there are springs 18 on the suspensions 15.

The device is clamped by a bracket 4 to a hook 19 of the lifting mechanism through an auxiliary hook 20 with a counter-weight: m 21.

Hook 20 is attached with a finger 22 to the bracket

23. Lastly hung on the cargo sling

24. The sling 24 is hung on the hook 19 of the crane. An auxiliary line is passed through the crane

25. connected to the end of the lever 9.

The device works as follows.

The device is inserted into the hole of the concrete element up to the stop of the end-piece with the help of an auxiliary line 25. At the same time, the lever 9 is brought into a vertical position, in which acob 4 is rejected by the pin 12 of the dog at the stop of the eccentric 7. The dog 11 engages with the table 6 tooth, the cable hooks 15 wind At the base of the lever rotating around the finger 5. The cams 16 fit into the jigs of the jelly, and the springs 18 are compressed. To bring the device into working position, the sling 25 is loosened: the crank 20 enters into the bracket 4, the elevation of which of the eccentric squeezes the dog 11 to engage with the tooth of the 6th head by the action of the springs 18. The cams 16 abut against the surface of the mounting hole of the concrete element . When raising the strop 24, the teeth of the cams 16 move apart 1klino1m 2 and slam into the surface of the assembly -turning concrete element. The element rises. After the element is mounted, the cargo sling 24 is lowered. The hook 20 is removed from chute 4 by the weight of the weight of the counterweight 21. The auxiliary sling 25 is tensioned. Lever 9 rises. The cams 16, embedded in the body of concrete, being stationary, pull the body and wedge down through the cable suspensions 15. Then the cams, freeing themselves from maple 2, enter the grooves of the body of the gripping device. The cycle is reversed. The pickup device is removed from the mounting hole with the help of an auxiliary strap 25. Present invention The pickup device for loads with an internal cavity according to the author. St. No. 359223, characterized in that, for the purpose of remote suspension of cargo using a single lifting mechanism, an eccentric with a groove is rigidly fixed on the bracket, and the swivel lever is equipped with a spring-loaded dog with pin, we will take the device hooked to the hook of the lifting mechanism through an auxiliary hook with counterweight.
