Description

Pr. Proposed stopper device for winch Presented on the drawing, in which FIG. 1 shows a general view of a device mounted on a winch shield; FIG. 2 is a vertical section of the glass cup and an internal view of the locking mechanism; and FIG. 3- general external view of the glass.

The locking device consists of a toothed disk D mounted on the winch shaft (Fig. 1), which has teeth that engage with a dog in the form of a crank lever B, one shoulder of which rests on the spring plate G, and the other shoulder stops the disk D by teeth. .

Piston D is located together with a dog in glass A attached to the shield of the winch frame and equipped with a corresponding hole for the protruding lever arm B and a hole for pushing the E-checks to enable and disable the dog.

For this purpose, the check E is pivotally connected by means of a crank lever D O and a ti p with the pedal J.

When the load is lifted, the disk D rotates the lever B with its teeth, and the spring raises the lever to the initial position along the passage of each tooth. Next / Finger again deflects the crank, which again rises, etc. If the handle of the winch is missed and the load starts to fall, then when the winch rotates in the opposite direction, the next tooth, the disk will meet the lever in such a position that it will not can be tilted back, whereby the D disc will delay the movement of the winch, and in order to lift the load again, you have to start turning the knob again.

When lowering the load, the effort of the worker is aimed at delaying the movement of the load down. Therefore, at the beginning of the descent, the lever V is fixed tightly with the E in the reclined position (Fig. 2). During the descent, it is necessary that the lever should start to act in the event that the worker misses the handle and is unable to delay the lowering of the load; at the same time, the lever must be placed in such a position that it stands against the move

winches, i.e. in the initial. For this purpose, the pedal W, with the lever system K, O, and R. Tee serves. Pressing the pedal, the worker pulls out the lever E laid under the lever at the beginning of the descent, thanks to which the dog lever B, under the action of the spring, will again be in its original position and lock the winch.

The subject of the patent.

The locking device for the winch, characterized by the use of a dog, having the form of a cranked lever D abutting with one shoulder in the spring piston G, located together with

with a dog in glass A, attached to the shield of the winch frame, provided with a corresponding hole for the other arm of the lever that protrudes from it, which does not prevent the rotation of the toothed disk D when the load is lifted by the winch and locks the D-drive for the teeth corresponding to the release What kind of doggie can be turned off by a pin D inserted in order to stop the dog in the holes of glass A and hingedly connected by means of a cranked lever K, O and ti R with the pedal G, by pressing which the check E is pulled out from Tacana A also releases the said dog.
