SU1221165A2 - Self-tripping gripping device - Google Patents

Description

The invention relates to the lifting of o-transport equipment, in particular to self-disengaging gripping devices, can be used in any branch of the national economy for loading and unloading operations and is an improvement of the known device described in ed. Sat No. 1079592.

The aim of the invention is to reduce the size.

FIG. 1 and 2 shows the device when loading various loads, side view; in fig. 3 - the same, in the unloaded condition; in fig. 4 is a section A-A in FIG. 3; in fig. 5 - interaction of parts of the device at the moment of uncoupling from the load.

The self-engaging gripping device comprises a body 1, which is a hollow cylinder with a sleeve 2 screwed into it, made with a shoulder 3 and an annular groove 4. The spring-loaded slider 5 rests on the shoulder 3 in a loaded state 6. The recess 7 is made inside the slide 5 In which is placed the spring 8, connected at one end with the slide 5 by means of the clamp 9 and screw 10, and the other with the housing 1 by means of the clamp 11 and the screw 12. The slide 5 is made with a slot 13, the lower part of which is connected by a jumper 14 (body floor zun) for supporting the C-shaped bracket 15 placed in the slot 13 parallel to it and eccentric with respect to the notch 16, while a is the distance from the vertical axis of the slide to the vertical axis of the element 17. Element 17 is the axis on which the bracket is hung 15. Bracket 15 in the loaded and unloaded states is supported in the bridge 14. This allows the bracket 15 to rotate counterclockwise only until it touches the bridge 14. In addition, the bracket 15 is always connected by a spring 18 to the axis 19 inserted into the body of the slide block 5, and Any tilt device is reliable of the bracket 15 presses the jumpers 14. The spring 18 through rod 20 is connected to a spring-loaded abutment 21.

The housing 1 in the upper part is provided with an opening 22 for connection to the slings 23.

Due to the fact that the spring 18 is connected by a thrust 20 to the stop 21 and with the axis 19 of the slide 5, it always presses the stop 21 to the bridge 24 of the bracket 15 and to the jumpers 14 of the slide 5. The bracket 15 is made with a groove 25 in which is placed on the axis 17 an emphasis 21, and an inclined part (bevel) 26 for convenience

work. The number of slings 23 depends on the nature of the load and the method of snapping, for example, 27 - overlap panel loop (Fig. 1 and 2).

The self-clutch gripper operates as follows.

When loading, for example, overlapping panels (Fig. 2), the slinger hand alternately presses the device on each hinge 27 of the panel that enters the slot

0 16 and slides along the inclined part (bevel) 26 of the bracket 15, deflects the spring-loaded bracket 15 clockwise (FIG. 3) and enters the upper part of the notch 16, and the spring 18 presses the bracket 15 to the jumper 14 of the slide 5,

and the panel loop is securely closed and practically cannot fall out.

When the load is lifted, the spring 8 expands, the slider 5 sags relative to the body 1, the stop 21, turning on the axis 17 counterclockwise, slips through

0 the bottom of the sleeve 2 is set to its original position. In this case, the slider 5 is supported by the protrusion 6 on the sleeve 2, which takes up the entire load of the weight of the load. The load is moved. After the load has been moved and installed in the right place, the spring 8 is compressed and drags up the slider 5, while the stop 21 rests on the bottom of the sleeve 2 and, by acting on the bridge 24, the bracket 15 rotates with the clip clockwise relative to the axis 17. The notch 16 is released from the bracket 15, the slider is moved up to its original position, and the panel loop 27 (Fig. 2) or sling 23 (Fig. 1) is released from the load.

When moving up the slider 5 stop 21

passes into the annular groove 4, and the spring 18 sets the bracket 15 and the stop 21 to its original position.

The device is ready for splicing the next load.

Due to the presence of a spring connecting

0, the slider body, the operational capabilities are expanded, and the reliability of the device is improved in all positions, even horizontal and inclined, the possibility of a hinge strap (panel) falling out when the device is tilted, since the clip is pressed against the jumpers. By placing a stretch spring inside the slider body, the compactness of the device is increased, the metal consumption is reduced by 20%. At the expense of beveling, the conditions of operation of the slinger are improved, since it is easier to connect the device with the load.
