DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In order to make the above-mentioned features and advantages of the utility model more obvious and easy to understand, the following embodiments are specifically cited and described in detail with the drawings.

[0018] Example: Figures 1 to 3 As shown, a mobile automatic submerged arc welding platform includes a square work platform 10, the bottom four corners of the work platform 10 are respectively fixedly connected with movable adjustable support legs 20, a transverse working groove 11 is provided in the middle of the work platform 10, two parallel transverse guide rails 12 are fixedly installed in the transverse working groove 11, an automatic submerged arc welding trolley 30 that can move left and right along the transverse guide rails 12 is placed in the transverse working groove 11, and self-adjusting welding roller frames 40 for driving the welding workpiece 50 to rotate are respectively placed under the left and right sides of the work platform 10. Among them, the automatic submerged arc welding trolley 30 and the self-adjusting welding roller frame 40 are both existing mature products.

[0019] The working principle of this embodiment is as follows: the movable adjustable support leg 20 can be adjusted in height according to the size of the welding workpiece 50, and can also be moved and adjusted according to the position of the working platform 10. When in use, the cylindrical or conical welding workpiece 50 is placed on the left and right self-adjusting welding roller frames 40, and the self-adjusting welding roller frames 40 drive the welding workpiece 50 to rotate through its active rollers. The operator operates the automatic submerged arc welding trolley 30 on the working platform 10 to perform welding work on the welding workpiece 50.

[0020] In this embodiment, the movable adjustable support leg 20 includes a hollow upper support leg 21 and a lower support leg 22 (both of which can be made of square steel pipes), the upper part of the upper support leg 21 is fixedly connected to the bottom of the work platform 10, the lower part of the upper support leg 21 is movably sleeved on the upper outer side of the lower support leg 22, the lower side of the upper support leg 21 is provided with two outer positioning holes 211 spaced apart from each other, the upper side of the lower support leg 22 is provided with at least three inner positioning holes 221 spaced apart from each other, the outer positioning holes 211 are fixedly connected to the corresponding inner positioning holes 221 through bolt and nut assemblies 23, and the lower end of the lower support leg 22 is fixedly connected with a braked caster 24. Among them, the braked caster 24 is preferably, but not limited to, a braked universal wheel; of course, the braked caster 24 can also be a braked track wheel, in which case a corresponding track needs to be set on the ground; it is specifically set according to actual needs.

[0021] When in use, the movable adjustable support leg 20 can be adjusted in height according to the size of the welding workpiece 50. The specific adjustment method is: first remove the bolt and nut assembly 23, then move the upper support leg 21 upward or downward to a predetermined height, and align the two outer positioning holes 211 of the upper support leg 21 with the two inner positioning holes 221 of the lower support leg 22, and finally install the bolt and nut assembly 23 to fix the upper support leg 21 and the lower support leg 22 relatively. When the work platform 10 needs to be moved, first lift the brake of the brake caster 24, then move the work platform 10 to a predetermined position, and finally press down the brake of the brake caster 24 to fix the position of the work platform 10.

[0022] In this embodiment, in order to enhance the structural strength of the movable adjustable support legs 20, a transverse connecting rod 25 is fixedly welded between the lower parts of the two upper support legs 21 on the front side and between the lower parts of the two upper support legs 21 on the rear side, a first oblique support rod 26 is fixedly welded between the left and right ends of the transverse connecting rod 25 and the corresponding side edges of the bottom of the working platform 10, and a second oblique support rod 27 is fixedly welded between the two upper support legs 21 on the left side and the corresponding side edges of the bottom of the working platform 10 and between the two upper support legs 21 on the right side and the corresponding side edges of the bottom of the working platform 10.

[0023] In this embodiment, in order to improve the welding efficiency, the number of the automatic submerged arc welding carriages 30 is two, and the two automatic submerged arc welding carriages 30 are respectively placed at the two ends of the transverse working groove 11. Since the transverse working groove 11 divides the working platform 10 into two halves, two operators can operate the two automatic submerged arc welding carriages 30 on their respective half of the working platform 10, and perform welding work on the welding workpiece 50 at the same time, which greatly improves the welding efficiency.

[0024] In this embodiment, in order to facilitate the operator to reach the working platform 10, a ladder 13 is fixedly connected to the front side of the working platform 10, and the lower part of the ladder 13 can be fixedly connected to the transverse connecting rod 25 located at the front side, so that the ladder 13 is more stable. When in use, the operator can climb up the working platform 10 through the ladder 13. In order to prevent the operator from falling, safety guardrails 14 are fixedly connected around the top of the working platform 10 to effectively ensure the safety of the operator.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
