DETAILED DESCRIPTION
[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The trolley body 1 includes a vehicle body 11 and four control wheels 12 arranged at the four corners of the vehicle body 11. The welding structure 2 includes a wire feed wheel 21, a control box 22, a flux box 23 and a welding gun structure 24. The wire feed wheel 21 and the control box 22 are arranged at the left end of the frame assembly 3, and the flux box 23 and the welding gun structure 24 are arranged at the right end of the frame assembly 3. The flux box 23 and the welding gun structure 24 are connected to the frame assembly 3 through an adjustment member 4, and the frame assembly 3 is connected to the vehicle body 11 through a base adjustment member 5. The submerged arc welding trolley of the present application sets the wire feeding wheel 21, the control box 22, the flux box 23 and the welding gun structure 24 on the frame assembly 3, and then the control box 22 controls the movement of the trolley body 1, thereby realizing the movement of the submerged arc welding trolley along the track. The submerged arc welding trolley can flexibly adjust the horizontal, vertical and height, so that the welding gun structure 24 has high flexibility and can adapt to different positions for welding.
[0036] like Figure 1 、 Figure 2 and Figure 3 As shown, the base adjustment member 5 includes a base screw 51, an adjustment base 52, a column carriage 53, and two base guide rails 54. The base screw 51 is arranged along the width direction of the vehicle body 11 and is located in the middle of the vehicle body 11. Both ends of the base screw 51 are fixed and rotatably mounted within the vehicle body 11 and extend outside the vehicle body 11. Base handwheels 511 are installed on the outer sides of the base screw 51. The base handwheels 511 are provided to rotate the base screw 51 to control the position of the adjustment base 52, thereby achieving longitudinal control of the adjustment base 52.
[0037] The adjustment base 52 is mounted on and threadedly connected to the base screw 51. The base guide rails 54 are arranged parallel to the axis of the base screw 51 and are located on both sides of the base screw 51. The diameter of the base guide rails 54 is larger than that of the base screw 51. Both ends of the base screw 51 and the base guide rails 54 are equipped with shielding plates 541, which are larger than the diameter of the base guide rails 54. The shielding plates 541 not only limit the position of the base screw 51 and the base guide rails 54, ensuring their fixed position and rotation within the vehicle body 11, but also block the base screw 51 and the base guide rails 54 to prevent welding slag and debris from entering the vehicle body 11.
[0038] The column drag plate 53 is fixed at the bottom of the rack assembly 3, and the column drag plate 53 is arranged above and fixed with the adjusting base 52. The sliding base 521 further extends a base ring 5211 fixed with the column drag plate 53, and the lower bottom of the column drag plate 53 is provided with a base groove 5311 corresponding to the base ring 5211.

The activity groove 111 is a waist-shaped groove with an area larger than that of the base ring 5211, and the area of the drag plate seat 531 is larger than that of the activity groove 111. The activity groove 111 with a suitable area provided on the vehicle body 11 can facilitate the sliding of the column drag plate 53, and also shield the activity groove 111 by the drag plate seat 531 to reduce the entry of welding slag and other impurities into the interior of the vehicle body 11, thereby reducing the impact on the driving of the trolley.
[0040] As shown in Figure 3 The adjusting base 52 is also sleeved on the base guide rail 54 and is arranged to slide relative to the base guide rail 54. The adjusting base 52 includes a sliding base 521 and four sliding sleeves 522. The sliding sleeves 522 are arranged outside the four corners of the sliding base 521 and are sleeved on the base guide rail 54. The adjusting base 52 slides with the base guide rail 54 through the four sliding sleeves 522 extending from the corners, thereby achieving the stability of the sliding of the adjusting base 52 and avoiding the side inclination of the sliding base 521 during the sliding process, which affects the accuracy of subsequent welding positioning.
[0041] Each sliding sleeve 522 is also provided with a coaxial rolling element 523. The rolling element 523 includes a cylinder wall 5231 and a plurality of rolling balls 5232.

The rolling balls 5232 are embedded in the cylinder wall 5231 and also abut the outer wall of the base guide rail 54. The original oil-containing copper sleeve in the sliding sleeve 522 is replaced by the rolling element 523, thereby reducing the friction. The original sliding friction is changed to rolling friction, which makes the sliding of the sliding sleeve 522 driving the sliding of the sliding base 521 more smooth and flexible. At the same time, lubricating grease can be directly added to the embedded position of the rolling balls 5232, which can avoid the direct coating of lubricating grease on the base guide rail 54, which is easy to be dried and evaporated by welding high temperature, or the influence of welding slag penetration and adhesion on sliding operation.
