SU26781A1 - Safety handle for lifting gear - Google Patents

Description

In the proposed safety handle l of lifting mechanisms, for the purpose of coupling it with the seed wheel, the sprocket is made in the form of an asterisk with a sleeve fixed to the axis end or shaft, when the handle is moved to the working position, the box is eccentrically and loosely mounted on the sprocket sleeve Handle with a shoulder. The box encloses a freely rotating figured dog, which enters the chain with an asterisk Lod by the influence of its own weight when turning the shoulder, and when lowering the shoulder and releasing the handle under the influence of the same. weights are disengaged.

In FIG. 1 schematically depicts the main view of the handle with the removed cover of FIG. 2-- vertical lateral discharge. /

The handle has a sleeve b with a star mail a (Fig. 1.2) attached to the end of the shaft in the lifting mechanism.

On the sleeve b, the box g, d is freely rotated eccentrically. Its crinkle is removable and held in place. two screws and a well, of which unt w serves as the axis for the figured pawl. .

 When the arm AND the handles are lowered, when the shaft rotates in either direction, the asterisk does not catch on which lies loosely, resting on the Cap Duckling {. If you start vra-d) .l :. . . -

And in the clockwise direction, then at a certain position of it, shown in FIG. 1 with a dotted line, 3 under the action of its weight is coupled with an asterisk a, from which moment the handle will rotate with sleeve b, asterisk a and shaft c. To obtain idle movement of the shaft, the arm is thrown counterclockwise and lowered in the lower vertical position, in which position the handle will be detached from the shaft of the shaft, since the dog, under its weight, will not engage with the asterisk a.

The subject matter of the invention. A safety handle for; 11 lifting mechanisms, characterized in that for the purpose of engagement with the gear, executed in the form of an asterisk and with the sleeve b fixed at the end of the axis or shaft c, when the handle is moved to the working position, it is applied eccentrically and freely mounted on the sleeve b asterisks a box d, d, associated with the shoulder of the handle and enclosing the play dog h, which rotates freely on the axle fixed in the box, when turning the shoulder and under the influence of its own weight, which comes into engagement with the asterisk a, and under by the influence of the weight of the output from the engagement with it when releasing the handle and shoulder i.opuskanii
