Description

t

The invention relates to lifting and transport engineering, in particular, cantilevers for repairing ship structures and equipment, such as repairing propeller heads,

A tilter is known that contains a frame on which a stand with a face plate rotatable around a horizontal axis is mounted, in which the ends of the grips P are mounted with the possibility of moving in the radial direction using a screw mechanism.

However, the known device has insufficient reliability of fastening the turned-on products of various configurations.

The purpose of the invention is to increase reliability. (

The goal is achieved by the fact that the grippers are made in the form of beams with a double-arm lever hinged at their free ends, one shoulder of which is provided

a pressure screw, and the other is made with a pressure screw to interact with the load.

FIG. 1 shows a tilter, side view; in fig. 2 is a view A of FIG. I; in fig. 3 - node I in figure 1.

The tilter contains a stand 1 mounted on the frame 2, a faceplate 3 with a turning mechanism including an electrically driven gearbox 4, which is engaged with a pinion wheel 5 mounted on the faceplate 3, and clamps mounted on the faceplate 3, and made in the form of a beam 6 hinged at its end

ts two shoulders lever 7, on one shoulder of which a clamping screw 8 is installed, and the other is made with a presser pin 9. On the faceplate 3 a paw 10 is mounted, made, for example, from channels forming a groove 11, in which the end of the bag 6 is installed the ability to move in the radial direction with the help of a vynf mechanism 12. A washer 3 in conjunction with a pinwheel 5. mounted on the shaft 13 mounted on a rack 1 with the help of I4 bearings. To securely fasten the product 15, in the faceplate 3, four paws 10 with the aforementioned equipment are installed, located at an angle of 90 around the faceplate.

The tilter works in the following way.

Before installing the workpiece: I5 into the turnpipe, the two lower beams 6 are interchanged and installed by screw mechanisms 12 along the slots I1 of the lower legs 10 in the radial direction depending on the diameter of the workpiece T5, and the paws 10 of the faceplate 3 should be set at an angle of 45 to the horizontal. The two upper beams 6, together with the levers 7, are guided to the workpiece 15 by means of screw mechanisms 12 along the grooves 1 of the upper legs 10. After installing the workpiece 15 on the faceplate 3, the alignment of the workpiece 15 and the faceplate 3 is checked, since the outer surface of the workpiece 15 may be deformed. If the axes of the workpiece and the faceplate 3 do not coincide, then the clamping screws 8 of the double-arm levers 7 carry out a fine adjustment of the coaxiality. This is done depending on the direction of displacement, for example, by unscrewing the clamping screws 8 of the shoulders of the double-arm levers 7 on one side, which, by means of movement, cause the double-shoulders of the arm 7 to rotate around the hinges and force the clamping pegs 9 of the levers 7 to release the workpiece 15, and by screwing in the clamping screws 8 on the opposite side, which cause the two shoulders 7 to rotate and thus

Press the clamping pins to press the workpiece 15. If the product 15 is rotated, it is necessary to turn on the electrically driven gearbox 4, which is engaged with the pinwheel 5. The pinwheel 5 - together with the plate 3 and the shaft 13 is rotated to the desired angle in bearings 14 , which are mounted on the rack 1, spontane | 1rova.nnoy on the frame 2.

The positive effect of using the invention is to reduce the number of gripping parts and exclude the hydraulic cylinder, which results in simplifying the gripping design and reducing the cost of gripping and the turn-over device as a whole. In the proposed turner, it is possible to center the product.
