Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a welding operation platform with a liftable pipe structure. Background Art

[0002] At present, the circumferential seam welding for the lengthening of known pipe segments is generally carried out by an automatic submerged arc welding machine. The automatic submerged arc welding machine has the advantages of high production efficiency, no arc light and less soot. However, the movement in the welding direction requires external force. Some factories with conditions adopt an automated robotic arm. By fixing the automatic submerged arc welding machine on the robotic arm, the welding direction is advanced. However, the cost of the automated robotic arm is relatively high, and after being arranged at a certain position, it can only operate within a limited range near the fixed point. Beyond this range, the robotic arm is unable to reach. Content of the Utility Model

[0020] In order to better understand the purpose, structure and function of the present utility model, the specific embodiments of the "liftable pipe structure welding operation platform" of the present utility model will be further described in detail below in conjunction with the drawings.

[0021] See Figures 1 to 3, in this embodiment, the welding platform includes a support frame 100 for support and a lifting platform 200 serving as the welding platform. The lifting platform 200 is slidably arranged on the support frame 100 in the up and down direction. At the same time, a fixing structure is arranged between the lifting platform 200 and the support frame 100 to fix the lifting platform 200 so that the lifting platform 200 is located at a fixed position on the support frame 100 to meet the welding requirements for circumferential seams of pipe segments with different diameters. A welding window 201 is arranged on the lifting platform 200, and directly below the welding window 201 is the pipe segment welding area 202. The pipe segment to be welded is placed on a rotating table frame, and the position to be welded is located in the pipe segment welding area 202. The operator welds the position to be welded through the welding window 201, and at the same time, the pipe segment to be welded rotates under the action of the rotating table frame to complete the welding of the circumferential seam of the pipe segment. Lifting lugs 101 are also arranged at the four corners above the support frame 100. After the circumferential seam of the pipe segment at one place is welded, the operator can lift and install this welding platform to other positions through the lifting lugs 101, and repeat the above operations to complete the welding operations for the circumferential seams of pipe segments at other positions. This welding platform has a low design cost, can move positions, and has a flexible working location, replacing the automated robotic arm and expanding the working range of the automatic submerged arc welding machine.

[0022] Further refer to Figure 2 , in this embodiment, to ensure the stability of the support frame 100, the support frame 100 includes columns 102 and cross beams 103. Diagonal braces 104 are fixedly connected between the columns 102 and the cross beams 103, and cross braces 105 are arranged between the columns 102. The support frame 100 is made of steel material, with low cost and stable structure.

[0023] Further refer to Figure 2 and Figure 3 , in this embodiment, the lifting platform 200 is provided with limit guide wheels 203, and the limit guide wheels 203 roll up and down along the columns 102 so that the lifting platform 200 can slide up and down relative to the support frame 100. The fixing structure includes positioning holes 106 and bolts 107. The positioning holes 106 are correspondingly arranged on the columns 102 and the side wall of the lifting platform 200. A number of positioning holes 106 are arranged at equal intervals from top to bottom on the columns 102. The lifting platform 200 is lifted to the corresponding position by a lifting machine. The positioning holes 106 on the columns 102 and the positioning holes 106 on the side wall of the lifting platform 200 are exactly aligned. At this time, the bolts 107 are passed through the positioning holes 106 to fix the lifting platform 200 to the support frame 100, completing the adjustment of the height of the lifting platform 200.

[0024] It should be noted that, in this embodiment, the fixing structure uses the design of cooperation between the positioning holes 106 and the bolts 107. However, in other embodiments, the fixing structure can be other existing design structures that can achieve relative fixation, such as structures of lead screws and motors, etc.

[0025] Further referring to Figure 1 and Figure 2 , in this embodiment, a vertical ladder 108 is fixedly connected to the support frame 100 for the operator to get on and off the platform; at the same time, in order to ensure the safety during operation, a guardrail 204 is provided at the edge of the lifting platform 200.

[0026] More specifically, in this embodiment, in order to ensure that the entire welding platform will not damage the working ground due to excessive weight, a backing plate 109 is provided at the bottom of each column 102 to increase the contact area with the ground and reduce the pressure.
