Detailed Implementation Manner

[0023] Please refer to Figures 1-4 , a butt joint rotating frame for steel pipe welding, including a lifting box 1. An adjusting mechanism 2 is arranged inside the lifting box 1. Four rotating legs 5 are fixedly connected to the bottom surface of the lifting box 1. The inner wall of each group of rotating legs 5 is rotatably connected with a support rod 6. By providing the rotating legs 5, the support rod 6 can be supported and grafted, and the device can be freely translated by using the support rod 6 and the rolling wheel.

[0024] The adjusting mechanism 2 includes two large bearings 201. The outer surface of each large bearing 201 is fixedly connected to the inner wall of the lifting box 1. Two triangular tracks 8 are arranged below the support rod 6. The bottom surfaces of the two triangular tracks 8 are commonly fixedly connected with three I-beams 9. By providing the triangular tracks 8 and the I-beams 9, height support and a stable translation line can be provided for the device.

[0025] The inner walls of two large bearings 201 are fixedly connected to a worm gear 202. A lead screw 203 is threadedly connected to the inner wall of the worm gear 202. Two limit wheels 7 are fixedly connected to the outer surface of each support rod 6. The inner wall of each limit wheel 7 is in contact with the outer surface of the triangular track 8. By providing the limit wheels 7 in cooperation with the triangular track 8, it can ensure that the device can move smoothly and straight, and can be moved to the required position according to the welding needs.

[0026] Two fixed seats 204 are fixedly connected to the inner bottom wall of the lifting box 1. Small bearings 205 are fixedly connected to the inner walls of each fixed seat 204. A rotating rod 206 is fixedly connected to the inner walls of the two small bearings 205. A turntable 3 is fixedly connected to the end of the rotating rod 206 away from the worm 207. A rotating handle 4 is fixedly connected to the left side surface of the turntable 3. By providing the turntable 3 and the rotating handle 4, power can be manually provided for the rotating rod 206.

[0027] One end of the rotating rod 206 away from the small bearing 205 penetrates through the lifting box 1 and extends to the outside of the lifting box 1. A worm 207 is fixedly connected to the outer surface of the rotating rod 206. The outer surface of the worm 207 meshes with the outer surface of the worm gear 202. A connecting block 12 is fixedly connected to the upper surface of the lead screw 203. The upper surface of the connecting block 12 is fixedly connected to the bottom surface of the rotating groove 208. By providing the connecting block 12 to bear the pressure of the rotating groove 208 and to disperse the pressure of the rotating groove 208, sometimes when the pipeline is large and heavy, it can prevent the rotating groove 208 from being bent.

[0028] Above the lead screw 203 is provided a rotating groove 208. Two threaded rods 209 are threadedly connected to the inner wall of the rotating groove 208. The ends of the two threaded rods 209 close to each other are rotatably connected to brake pads 210. Two rotating wheels 211 are rotatably connected to the inner wall of the rotating groove 208. Four blocking rods 10 are fixedly connected to the outer surface of each threaded rod 209. A limiting strip 11 is fixedly connected to the bottom surface of each brake pad 210. The outer surface of each limiting strip 11 is slidably connected to the inner wall of the rotating groove 208. By providing the blocking rods 10 to increase the resistance of rotating the threaded rods 209, the limiting strips 11 play a role in limiting the brake pads 210 to ensure that the brake pads 210 are not easily shaken.

[0029] The working principle of the utility model is as follows: when in use, four devices can be placed on the same set of triangular tracks 8, and the rotating wheels 211 of each two devices can hold up a pipe, and then the device can be moved by the limiting wheel 7 until the two held-up pipes are butted together. If the heights of the two pipes are deviated at this time, the heights of two of the devices can be adjusted. At this time, the staff manually rotates the rotating handle 4, and the rotating handle 4 can drive the turntable 3 to rotate. By utilizing the fixed connection between the turntable 3 and the rotating rod 206, when the turntable 3 rotates, the rotating rod 206 can be driven to rotate. At this time, the two fixing seats 204 are used to limit and fix the small bearings 205, and the rotating rod 206 is used to fix the inner walls of the two small bearings 205 respectively. The worm 207 is fixedly connected, and the rotating rod 206 and the worm 207 are fixedly connected. When the rotating rod 206 is rotated, the worm 207 can be driven to rotate. The two small bearings 205 limit the rotation of the rotating rod 206 to ensure that the rotating rod 206 is not easy to shake. At this time, the relationship between the meshing connection between the worm 207 and the worm wheel 202 and the threaded connection between the worm wheel 202 and the worm 207 are utilized. When the rotating rod 206 rotates, the screw rod 203 can be driven to move up and down. The outer rings of the two large bearings 201 are fixedly connected to the inner wall of the lifting box 1, and the inner rings of the two large bearings 201 are fixedly connected to the worm wheel 202 to ensure that the screw rod 203 is not easy to shake during the up and down lifting process. If the height of the pipeline is determined;

[0030] When the height and position of the two pipes are determined, the braking function can be used to clamp the welding pipe to prevent the welding pipe from changing its position during the welding process. First, the staff manually rotates the threaded rod 209, and utilizes the threaded connection relationship between the threaded rod 209 and the inner wall of the rotating groove 208 to rotate the two threaded rods 209 to move in relative directions. Utilizing the rotational connection relationship between the threaded rod 209 and the brake pad 210, the threaded rod 209 can drive the brake pad 210 to move when it moves, and when it slowly approaches the rotating wheel 211 until the rotating wheel 211 is clamped, it can brake and stop the rotating wheel 211 from moving. The limiting strip 11 can limit the brake pad 210 inside the rotating groove 208, so that the height and position of the welding pipe can be adjusted as needed on the steel pipe welding docking rotating frame.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
