Claims

The gripping device is designed to grip loads, mainly fuel cells 1, equipped with a die with a figured head, and includes a housing 2 connected through a shock absorber 3 with an eye 4 for 25 hooks on a crane hook. A window 5 is made in case 2, and a flange b is fixed on its outer surface, on which pins 7 and 8 with conical ends, which are the means of orienting different diameters 30, are installed. in contact with the holes 9 intended for them in the rack 10 (of the supporting structure for the installation of fuel cells). A spring-loaded figure lever 11 is attached to the flange of the ball, which is in engagement with the forging groove 12 of the slide 13 with the working body 14. At the last, the profiled locking arms 15 that engage the cylindrical projections 16 of the fuel element 1 are hinged through the control rod 17 with the steering wheel 18. On the case 2 there are handles 19 for the convenience of the staff; when the gripping device is installed on the rack 10. The working organization 14 has a stop 20 for mounting the gripping device on the fuel cell 1. at the time of its engagement. The control rod 17 has an axis 121 with rollers 22. The axis 21 passes through the groove 23 of the slide 13. THE ROLLERS 22 are placed in the groove 24 of the housing 25 DJTypBana 18. In the lower part of the slide 13 a sleeve 26 is installed, connected through the axis 27 passing through the groove 28 the slider 13, with the control rod 17. The profiled levers 15 have rollers 29 and axes of rotation 30. The device works in the following way. It is hung on the hook 4 on the hook of the lifting mechanism (not shown in the drawing), then installed in the opening of the rack 10 so that the pins 7 and 8 are aligned with the corresponding holes 9, which guarantees the orientation of the profiled levers 15 to the required position for engagement with the cylindrical the protrusions 16 of the fuel cell 1. At the same time, the lever 11 rotates from its axis, since its lower surface rests against the supporting surface of the rack BEFORE. One end of the lever 11 extends from the lateral groove 12 of the slide 13, preventing it from moving downward by fixing the slide 13 in the initial position when the gripping device is inaccurately mounted on the rack when the pins 7 and 8 are not aligned with the holes 9 in the rack 10 After the lever 11 releases the slider 13, the slider is further lowered together with the working body 14 until the stop 20 touches the upper end of the fuel cell 1. Then, using the wheel 18, lower the rod 17 until the upper edge of the body 25 is aligned to HAZARDS on the surface of the slider 13, which corresponds to the full engagement of the levers 15 with the fuel cell 1. At the same time, when the handwheel 18 rotates along the threaded part of the slider 13 controls the rod 17, the boom 17 is lowered due to the downward movement of the axle 21 the groove 23 of the control rod 17. The rollers 22 rotate on the axis 21 in the groove 24 of the housing 25 of the steering wheel 18. The control rod 17, lowering, moves down the sleeve 26 associated with the control rod 17 axis 27 through the groove 28 in the control rod 17. When this slider 13 remains stationary, and the sleeve 26, moving From the bottom, with its projection, it acts on the rollers 29 of the profiled arms 15. The levers 15 rotate on the axles 30 and, with their hooks, engage the cylindrical projections 16 of the fuel cell 1. After the gripping device is connected to the fuel cell 1, it is transported by a lifting mechanism to the required a place. Disengagement from the fuel cell occurs in reverse order. The invention provides a quick orientation of the device with respect to the load and its secure grip, eliminating the possibility of triggering the gripping bodies if they are incorrectly oriented. A formula for gripping devices equipped with a die with a figured head, comprising a housing, a slider disposed therein with a groove on a side surface, gripping arms and a gripping lever control mechanism, characterized in that, in order to improve reliability and productivity, it is provided device for orientation of the body relative to the load, containing a flange fixed to the body with vertically mounted on it pins of different diameters, having conical tips, and hinged A lever on the flange for interacting with the slide.
