Detailed Description

As shown in figure 1, the automatic lifting rotary platform for the welding of the reaction kettle comprises a slide rail 1, wherein lifting rotary devices 2 are symmetrically arranged on the left and right sides of the slide rail 1 in a mirror image mode. Every lifting and rotating device 2 includes lifting and jacking mechanism 3, supports slewing mechanism 4, and lifting and jacking mechanism 3, support slewing mechanism 4 between connect through first cylinder 5. The lifting and jacking mechanism 3 is used for jacking the semi-finished reaction kettle, and the supporting and rotating mechanism 4 is used for supporting and rotating the semi-finished reaction kettle.

As shown in fig. 2, the lifting and jacking mechanism 3 includes a lower slide rail 3.1 and an upper slide rail 3.2, the lower slide rail 3.1 is arranged on the lower support in pairs, and the upper slide rail 3.2 is arranged on the upper support in pairs. Four sliding blocks 3.3 are arranged in the lower sliding rail 3.1 and the upper sliding rail 3.2 in a sliding way, and two groups of fork rods 3.4 are hinged with the upper sliding blocks 3.3 and the lower sliding blocks 3.3. The fork arm 3.4 is composed of two connecting rods, the middle parts of the two connecting rods are hinged with each other, and the two connecting rods are similar to the scissors in hinge joint. And connecting plates are fixed between the two groups of sliding blocks 3.3 at the left and right of the lower end, and each connecting plate is driven by a second cylinder 3.5. When the two second cylinders 3.5 extend, the fork rods 3.4 are folded, and the upper sliding rail 3.2 is lifted. When the two second cylinders 3.5 contract, the fork rod 3.4 is opened, and the upper sliding rail 3.2 descends.

Be fixed with crossbeam 3.6 at last slide rail 3.2 one end, crossbeam 3.6 is connected with fixing base 3.7, and four the same third cylinders 3.8 are installed to circumference on the fixing base 3.7, and the third cylinder 3.8 other end is connected with top 3.9, and top 3.9 is rotatable gyro wheel, and the gyro wheel is tight to the reation kettle inner wall top when third cylinder 3.8 stretches out.

As shown in fig. 2, the supporting rotation mechanism 4 includes a housing 4.1, rollers 4.2 are mounted on the housing 4.1 on the left and right, and the rollers 4.2 on the left and right are arranged in pairs. Four rollers 4.2 can support the outer wall of the reaction kettle. The driven gears 4.5 are coaxially connected to one group of rollers 4.2, the two driven gears 4.5 are both meshed with the driving gear 4.4, and the driving gear 4.4 is connected with an output shaft of the first motor 4.3. Can drive driving gear 4.4 through motor 4.3 like this and rotate, driving gear 4.4 makes two liang of driven gear 4.5 rotate, and then makes two gyro wheels 4.2 rotate thereupon, can make reation kettle also send the rotation like this, then makes things convenient for the welding of circumferential weld.

A guide rod 3.10 is fixed on the lower slide rail 3.1, and the upper end of the guide rod 3.10 freely penetrates through the upper slide rail 3.2. This makes the upper slide rail 3.2 rise and fall more stably.

And traveling wheels 6 are arranged at the bottoms of the lifting jacking mechanism 3 and the supporting rotating mechanism 4. Therefore, the lifting jacking mechanism 3 and the supporting and rotating mechanism 4 can move back and forth.

The working principle and the process are as follows: the lifting rotary devices 2 are pulled outwards, so that the two groups of lifting rotary devices 2 are separated by a certain distance. The bent cylinder is then placed between two sets of lifting and rotating devices 2 for spot welding. After spot welding, the reaction kettle of the semi-finished product forms a large thin-wall cylinder. The lifting rotating device 2 is manually pushed to be close to the thin-wall cylinder. Crossbeam 3.6, fixing base 3.7, third cylinder 3.8 etc. stretch into the thin wall cylinder earlier, support slewing mechanism 4 and lie in the thin wall cylinder outside. The third cylinder 3.8 extends out, and the top 3.9 is tightly pressed on the inner wall of the thin-wall cylinder. Subsequently, the second cylinder 3.5 stretches out, goes up slide rail 3.2 jack-up, and crossbeam 3.6, fixing base 3.7, third cylinder 3.8 drive the thin wall cylinder and rise a section distance. When the thin-wall cylinder is higher than the supporting and rotating mechanism 4, the first air cylinder 5 extends out, the supporting and rotating mechanism 4 is located below the thin-wall cylinder, then the second air cylinder 3.5 contracts, the upper sliding rail 3.2 descends for a short distance, and the thin-wall cylinder falls onto the roller 4.2. Subsequently the third cylinder 3.8 contracts and the plug 3.9 detaches from the thin-walled cylindrical inner wall. And starting the first motor 4.3, and rotating the roller 4.2 so as to rotate the thin-wall cylinder, thereby welding a circumferential annular welding seam on the spot-welded thin-wall cylinder.
