Description

The invention relates to lifting equipment, in particular, to self-disengaging gripping devices, and can be used in the los industry, ports, construction, and other areas of the national economy. A self-disconnecting hook, containing a cramp connected to the hoisting polyslast, a mechanism of fixation during the alternation of the operations of seizure and release of the cargo is known. On the hinge axis of each gripping paw a counter-load is swivel mounted, the locking mechanism is implemented in the form of a spring-loaded lever and a flexible C 1 link. However, the shortcomings of this design include its bulkiness and complexity. Closest to the proposed self-disengaging gripping device containing a body hinged on the hook of the load-lifting mechanism by means of an axis, consisting of two cheeks, filled with U-shaped cuts, between which are hooked and hooked with an eccentric-and-relatively cut and made in the form of a C-shaped bracket with a protrusion and a mechanism for opening the hook, which includes a holding device which is a rigidly interconnected plate on which a spring is mounted another stop for engaging the clevis protrusion, and a cable for gripping the load 2 connected to the hook opening mechanism. The disadvantages of the known construction are the cumbersome complexity of the complex construction, unreliability in operation, due to the possibility of subsidence of the C-shaped bracket on the shock absorber, which can lead to non-sabotage of the device, since the vibration of the bracket does not enter into the vibration of the vibration of the slide, the purpose of the invention reliability of the device. The goal is achieved by the fact that in a device containing a housing visited on a hook by means of an axle, consisting of two jaws, made with U-shaped notches, between which a hook is hinged, eccentrically placed relative to the U-shaped notch and a C-shaped staple with a protrusion, and a mechanism for opening the hook, including a holding device, which is a rigidly interconnected plate, Hav, which has a spring stop for borrowing strap with a stupa, and connected with the hook opening mechanism to pick up the load, the retaining device plates are hingedly mounted on the axis of the suspension, spring-loaded relative to it, and filled with lugs and a lug with a cable for gripping the groove. This spring stop is made-shaped and rigidly fixed on the fins of the retaining device with a hubbing, opposite to the position of the grooves, and on the cheeks of the case there is a rigid stop-retainer of the clip. FIG. 1 with a schematically depicted the proposed device (with a dot-dotted line I is shown the rotation of the bracket when the cable is inserted into the pharynx, the dot-dotted line Q is the turn of the retaining device plate (lifting load); Fig. 2 is view A in Fig. 1; Fig. 3 - one of the possible variants of the protrusion of the C-shaped bracket and the plate of the holding device. The self-engaging gripping device comprises a body consisting of two cheeks 1, made with U-shaped notches 2 for accommodating a choker ring in them. Between the cheeks 1 with an eccentric In this case, the hook is made in the form of a C-shaped bracket 3 with a protrusion 4. Always due to its own weight of the hook and its eccentric suspension, it overlaps the notch 2 and rests against a rigid rotation stop 5, which is attached to the cheeks of the case. includes a holding device, which is a rigidly interconnected strip 6, spring loaded 7. On the plates 6 is mounted U-shaped spring stop 8, interacting with the protrusion of the C-shaped bracket. In addition, there may be another variant of implementation: for example, a protrusion 9 is fixed on the plates, and a C-shaped clip is fixed to a spring stop 10, the plates 6 of the retaining device are hinged on the axis 11 of the suspension and are made with lugs 12 for connection to the cable 13 for grabbing cargo. The operation of the device is as follows. In the cutout 2 of the cheeks 1, a choker cable is inserted, which rotates the C-bracket 3 clockwise.

and goes upwards to step 2. Then the Shaped bracket 3, turning counterclockwise under its own weight, closes the notch 2, and the ring hangs on the bracket 3, which abuts against the turn stop 5. The other end of the choker, threaded under the weight, is fastened in the eyelet 12 plates 6. While lifting the load due to the eccentric attachment of the C-shaped bracket 3, it tries to turn counterclockwise to the limiter 5, hopefully fix the choker ring in the notch 2. At the same time, when the load is lifted, the plates 6 are turned clockwise e, compressing the spring 7, spring support 8, deflection, slides the protrusion 4 of the bracket 3, and the plates 6 lie on the speed of 3 (dash-dotted line O), fixing the bracket 3 even more reliably. When downy. 20, the spring 7 is expanded by turning the plate 6 counterclockwise, the spring stop. 8 rests on the protrusion 4 and turns the sko 3 clockwise, pulling it out from under the choker ring, which, when fully opened, the notch 2 feeds down. Bracket 3 returns to its initial position.

The lifting mechanism pulls the cable out from under the load, since its one end is fixed to the plaster b. Devices in ready to seize the next load.

The use of the proposed advanced design device

Compared to the prototype, it has a greater compacting of the location of the plates on the axle for under: weight to the load rope, which allows us to reduce the size of the gabarct and, of course, metal consumption, by 2 times, to simplify the box.

G2 raises the safety precautions in the work, at the point of strict fshssatski C-shaped bracket with a spring stop.
