[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0029] See also Figure 1-5 The utility model provides a technical solution: a limiting wheel of a spiral seam submerged arc welding steel pipe machine, comprising a spiral steel pipe 100 and a horizontal slide 200 horizontally mounted below the spiral steel pipe 100, and two limiting mechanisms 300 respectively arranged on both sides of the spiral steel pipe 100 and symmetrically distributed, the horizontal slide 200 comprises a slot box 210 and two movable seats 220 respectively slidably assembled on both sides of the slot box 210 and supported by the limiting mechanism 300, and a double-headed double-rod cylinder 230 embedded in the slot box 210 along the length direction of the slot box 210, the two output ends of the double-headed double-rod cylinder 230 are respectively fixedly connected to the two movable seats 220, the limiting mechanism 300 comprises a fixed seat 310 and a screw slide assembly 320 mounted in the fixed seat 310 along an inclined direction, and a limiting wheel structure 340 distributed along the horizontal plane direction is mounted on the slide seat of the screw slide assembly 320 through a mounting frame 330.

[0030] Based on the above-mentioned structural setting, the limiting wheel of the spiral seam submerged arc welding steel pipe machine is composed of a spiral steel pipe 100, a horizontal slide 200 and two limiting mechanisms 300, wherein the horizontal slide 200 is arranged below the spiral steel pipe 100 to provide structural support for the two limiting mechanisms 300. Specifically, during the working process, the operator adjusts the horizontal slide 200 and the two limiting mechanisms 300 according to the specifications of the spiral steel pipe 100 to be transported. On the limiting mechanism 300, the operator controls the screw slide assembly 320 to realize the lifting and lowering of its slide seat along the inclined direction, thereby adjusting the height of the two limiting wheel structures 340 and realizing the coarse adjustment of the spacing between the two limiting wheel structures 340. On the horizontal slide 200, the operator controls the double-headed double-rod cylinder 230, and under the action of the synchronous extension and retraction of its two output ends, the two limiting wheel structures 340 can be driven respectively. The positioning mechanism 300 approaches and moves away from each other, and in the process of the two limiting mechanisms 300 approaching, the two limiting wheel structures 340 can realize the limiting support of the spiral steel pipe 100, and then the fine adjustment of the distance between the two limiting wheel structures 340 can be realized. After the debugging is completed, the spiral steel pipe 100 is spirally conveyed along its axial direction, and the limiting conveying is realized by two limiting wheel structures 340 arranged on both sides thereof. The limiting wheel of the spiral seam submerged arc welding steel pipe machine is provided with a horizontal slide 200 and two limiting mechanisms 300 for limiting support of the spiral steel pipe 100. At the same time, in conjunction with the screw slide assembly 320 erected in the fixed seat 310 along the inclined direction, the height of the two limiting wheel structures 340 and the distance between the two can be adjusted, so that it can adapt to the limiting operation of spiral steel pipes 100 of various specifications and sizes, thereby improving the applicability and flexibility of the limiting wheel structure 340.

[0031] Furthermore, it also includes a support seat 240 fixedly installed on the top of the trough box 210 and placed directly below the spiral steel pipe 100. The support seat 240 includes a stand 2410 and a trough column 2420 vertically welded to the top of the stand 2410. The top of the trough column 2420 is movably embedded with a ball 2430, and the outer fixed cover of the ball 2430 is provided with a cover shell 2440 for partially exposing it. Among them, the horizontal slide 200 is arranged perpendicular to the axial direction of the spiral steel pipe 100 and fixedly installed below the spiral steel pipe 100. The horizontal slide 200 provides support for the spiral steel pipe 100 through the support seat 240 fixedly installed on the top thereof. Since the spiral steel pipe 100 is spirally transported along its axial direction, with the help of the ball 2430, the stability of the transportation of the spiral steel pipe 100 can be ensured without affecting the surface quality of the spiral steel pipe 100.

[0032] Furthermore, the mounting frame 330 is composed of an assembly plate 3310 and a bracket 3320 welded on the assembly plate 3310 for mounting the limiting wheel structure 340. The assembly plate 3310 is fixedly mounted on the slide seat of the screw slide assembly 320, and the bracket 3320 is welded on the assembly plate 3310 and provides structural support for the installation of the limiting wheel structure 340 along the horizontal plane.

[0033] Furthermore, two parallel rails 350 are fixedly connected to both sides of the fixed seat 310, and the assembly plate 3310 is slidably assembled on the two rails 350. The slide of the screw slide assembly 320 is embedded in the fixed seat 310. At the same time, the fixed seat 310 provides a limit support for the slide, so that the slide can be lifted and lowered with the rotation of the screw. The two rails 350 arranged on both sides of the fixed seat 310, on the one hand, further ensure the stability of the sliding of the mounting frame 330. On the other hand, with the movement of the horizontal slide 200, the two limit wheel structures 340 limit the spiral steel pipe 100. The assembly plate 3310 slidably assembled on the two rails 350 ensures the support strength of the mounting frame 330 to the limit wheel structure 340.

[0034] Furthermore, the limiting wheel structure 340 is connected to the bracket 3320 through the damper 3330 installed on the bracket 3320, and the installation end of the damper 3330 is provided with a dial 3340 for adjusting the rotation angle. The setting of the damper 3330 can allow the diameter error of the spiral steel pipe 100 due to the manufacturing process, and since the spiral steel pipe 100 is spirally transported along its axial direction, in order to further ensure the stability of the transportation of the spiral steel pipe 100, the limiting wheel structure 340 can be rotated to an angle compatible with the spiral direction for installation, and the setting of the dial 3340 facilitates the angle adjustment operation of the limiting wheel structure 340 during the installation process.
