使用时，首先调整千斤顶8将回转底架23放平，回转底架23四周可采用千斤顶8或其他填充物硬支撑(如图2所示)，此时焊枪6翻转至最右侧的地面位置，为不妨碍压力容器10的吊装，缓缓将压力容器10吊入回转平台21，对准定位装置3，以定位装置3为粗定位装置、通过转动手轮427，调节滚轮421的位置，完成对压力容器的精确定位，同时，将压力容器10夹紧以防止翻转过程容器位置发生偏移，然后，撤除将倾斜侧的千斤顶8，换成高强度泡沫垫，顶起右侧的千斤顶8，将回转装置2倾斜至与水平面呈一定的角度，符合该类压力容器焊接工艺所需的角度相关要求，此时，可将焊枪夹持装置5翻转至工作位置，调整焊枪6的位置并固定，开启控制箱7电源，减速电机24开始工作带动回转平台21低速回转，此时，在焊接移位控制箱7的变频控制下，装有焊枪6的焊枪夹持装置5开始配合工作。焊接过程中科根据需要，操作人员可以随时登上焊枪调整工作台9，只需根据压力容器10的位置，调整焊枪夹持装置5的伸缩杆53、焊枪十字调整架55、传动块56及相应的螺钉，将焊枪6位置调整到准确位置，整个操作过程方便简单。When in use, first adjust the jack 8 to put the rotary base 23 flat, and the surrounding of the rotary base 23 can be supported by jacks 8 or other fillers (as shown in Figure 2), at this time the welding torch 6 is turned over to the rightmost position on the ground , in order not to interfere with the hoisting of the pressure vessel 10, slowly hoist the pressure vessel 10 into the rotary platform 21, align the positioning device 3, use the positioning device 3 as a rough positioning device, and adjust the position of the roller 421 by turning the hand wheel 427 to complete For the precise positioning of the pressure vessel, at the same time, clamp the pressure vessel 10 to prevent the position of the vessel from shifting during the overturning process. Then, remove the jack 8 on the inclined side and replace it with a high-strength foam pad, and jack up the jack 8 on the right side. Tilt the rotary device 2 to form a certain angle with the horizontal plane, which meets the angle-related requirements required by the welding process of this type of pressure vessel. At this time, the welding torch clamping device 5 can be turned over to the working position, and the position of the welding torch 6 can be adjusted and fixed. Turn on the power supply of the control box 7, and the reduction motor 24 starts to work to drive the rotary platform 21 to rotate at a low speed. At this time, under the frequency conversion control of the welding displacement control box 7, the welding torch clamping device 5 equipped with the welding torch 6 starts to work together. During the welding process, according to needs, the operator can mount the welding torch adjustment table 9 at any time, and only need to adjust the telescopic rod 53 of the welding torch clamping device 5, the welding torch cross adjustment frame 55, the transmission block 56 and the corresponding The screw is used to adjust the position of the welding torch 6 to the exact position, and the whole operation process is convenient and simple.
本发明焊接大型压力容器立式环缝的合格率达百分之百，保证了产品质量，提高了压力容器的使用寿命。The qualification rate of welding the vertical circular seam of a large pressure vessel reaches 100%, which ensures the product quality and improves the service life of the pressure vessel.
