Abstract

The invention relates to a lifting and transport technology, in particular to grips for products having openings. The aim of the invention is to expand the scope. The grip includes a housing 1 with a threaded bushing 2 having an eye 3. A rocker arm is placed on the axis 5 on the axis 5, a spring-loaded pusher 6 made on the same end with a groove, and a spring-loaded locking steria-9, which interacts with a groove $$ (L $

The pusher 6. The pusher from the side of the second end is connected by a flexible rod to the rocker at a point offset by

The invention relates to lifting and handling equipment, in particular to gripping devices.

The purpose of the invention is to expand the scope.

FIG. Figure 1 shows the gripper for products with a hole, stand-by positions; in fig. 2 - capture, the moment of entry into the hole; in fig. 3 - the same, the moment of lifting the product; in fig. 4 - the same, the moment of withdrawal from the hole; in fig. 5 shows the node I in FIG. one.

Capture consists of a body. 1, on which the threaded bushing 2 is fixed with an eyelet 3 of the rocker arm 4 installed eccentrically fixed on the axis 5 in the housing of the spring-loaded pusher 6. On the housing 1 there is a stop 7 that interacts with the end of the threaded bushing through the spring 8. Inside the housing 1 with the possibility of vertical moving there is a fixing rod 9, which interacts with its lower end with the lateral surface of the pusher 6, which has a groove on the end for power engagement with the clamp 9 .. To the upper end of the fixing rod 9 along The bend pull 1 is connected to move the locking rod 9 upwards manually. This is necessary to remove the fixation from the pusher 6. The second end of the pusher 6 (right) is connected by the flexible rod 11 to the rocker arm 4 at point 12 (Fig. 5), displaced relative to the axis 5 of rotation of the rocker arm 4 in the direction opposite to the displacement of the center t the tin of the specified rocker (in Fig. the center of the tin is shifted to the right from the axis 5).

In order to grip the product by hole, it is preliminarily hand-held with the help of a pull-rod 10 to raise the clamp 9 to release the fixation from the pusher 6, if the latter was previously in a fixed position

relative to its center of gravity. 5 il.

right). Capture is ready for operation (Fig. 1). Then, the grip for the eyelet 3 is directed downward, pressing the rocker arm 4, pivotally mounted on the axis 5, to the wall of the opening of the product being lifted. At this moment, the pusher 6 is in an average (not non-fixed) position under the action of forces from the rocker arm 4 (Fig 2). When the extreme point of the yoke 4 passes through the inner edge of the product hole, the abutment 7 is in contact with the outer surface of the lifted product, compressing the spring 8, and the pusher 6 is released from the load and pushes the rocker arm 4, turning it through a certain angle. At the moment, the left (in FIG.) End of the rocker arm 4 extends beyond the edge of the product hole. The beam 4 more hole lifted product and overlaps it.

After that, the grip moves upward, until the rocker arm 4 adjoins the product under the action of the spring 8, which holds the grip in that position. At the same time, the yoke 4, rotating, through the flexible rod 11 moves the pusher 6 in the direction of compression. his springs. In the horizontal position of the rocker arm 4, the retainer 9 under the action of either a spring or a gravity force enters the end groove of the pusher 6, fixing it in the rightmost position (Fig. 3). To pull the grip out of the hole, press the eye 3 with the hand, compressing the spring 8, lower the grip to a depth sufficient for the rocker 4 to occupy a vertical position (Fig. 4). The grip is ready for opening.

The present invention reduces the number of workers engaged in slinging operations by about two times by eliminating the need to access the hole from the bottom and, as a result, makes it possible to use the grip by one worker.
