Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to a steel pipe rolling welding device. Background Technology

[0002] When welding existing steel pipes, workers need to first spot weld the joint of two steel pipes for simple fixation. Then, workers weld around the entire circumference of the steel pipes to complete the welding. If the steel pipes are placed on a rolling device for rolling, the protrusions from the spot welds will affect the normal rolling of the steel pipes. The existing rolling device consists of two rollers. To ensure the synchronization of the two rollers, a toothed belt is required for transmission. Once the distance between the rollers changes, the toothed belt will not mesh with the rollers, and the rollers will not be able to transmit power.

[0003] Chinese Patent No. CN202310317020.0 discloses a welding and butt joint device and method for water supply and drainage steel pipes. Through the cooperation of a lead screw and a driving bevel gear, the motor first drives the lead screw to rotate, causing the first and second clamping platforms to tighten inwards. This ensures that the surfaces of the first and second clamping platforms are tightly fitted to the surface of the steel pipe, thus installing the steel pipe to the center position inside the first and second clamping platforms. Subsequently, a fixing plate is installed on the surface of a locking plate, and a locking pin is inserted into the through hole on the surface of the locking plate, allowing the device to clamp the steel pipe. Through the cooperation of a positioning pin and a positioning hole, the two steel pipes are fitted together, with the positioning pin engaging the positioning hole to position the steel pipe. This facilitates positioning during welding between the steel pipes and prevents gaps or misalignment during the fitting process. The support arc plate, after the steel pipe is clamped, is ejected by the elastic potential energy of a compression spring and fits against the surface of the steel pipe, thus supporting the steel pipe and preventing wobbling and misalignment during welding. When the device needs to weld steel pipes at different angles, a clamping mechanism can be rotated to the corresponding angle so that the two steel pipes form a specified angle, thereby enabling the device to weld steel pipes with different angle requirements.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] The structural design of the device makes it very difficult to separate the first clamping platform and the second clamping platform. When performing rolling welding on both ends of the same steel pipe, the steel pipe needs to be inserted between the first clamping platform and the second clamping platform to clamp the middle part of the steel pipe. Since the steel pipe is heavy, it is difficult and laborious to insert.

[0006] Therefore, providing a steel pipe rolling welding device that facilitates the fixing of steel pipes is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the difficulties in separating the first and second clamping platforms due to the structural design of the existing device. Furthermore, when performing rolling welding on both ends of the same steel pipe, the steel pipe needs to be inserted between the first and second clamping platforms to clamp the middle portion. Because the steel pipe is heavy, this insertion is cumbersome and laborious. Therefore, this utility model provides a steel pipe rolling welding device that facilitates the fixing of steel pipes.

[0008] To achieve the above objectives, this utility model provides a steel pipe rolling welding device, the device comprising: a frame, a first rotating frame, clamping blocks, a first driving mechanism, and a second driving mechanism.

A plurality of first driving gears that mesh with the inner ring tooth are rotatably arranged around the periphery of the frame. The synchronization component is arranged on the frame to drive each first driving gear to rotate synchronously.

[0010] Preferably, the synchronization component includes: a synchronization pulley, a synchronization belt, and a dual-axis motor. A synchronization pulley is coaxially arranged on one side of the first drive gear. The dual-axis motor is mounted on the frame to drive any of the first drive gears to rotate. The number of synchronization belts corresponds to the number of synchronization pulleys, and each synchronization belt is fitted onto adjacent synchronization pulleys at opposite ends.

[0011] Preferably, the clamping block is provided with limit sliders on opposite sides, and the first rotating frame is coaxially arranged with limit grooves corresponding to each limit slider.

[0012] Preferably, the second driving mechanism includes: a second rotating frame and a driving assembly. The second rotating frame is in the shape of a "C" adapted to the first rotating frame and is rotatably mounted on the first rotating frame coaxially via the driving assembly. The clamping block has protruding locking posts on its surface, and the second rotating frame has coaxially arranged arc-shaped grooves corresponding to each locking post.

[0013] Preferably, the drive assembly includes a rotary motor and a second drive gear. An outer ring tooth is coaxially arranged around the outer side of the second rotating frame. The second drive gear is rotatably mounted on the first rotating frame via the rotary motor and meshes with the outer ring tooth.

[0014] Preferably, the outer end of the clamping block is provided with an arc-shaped block that can fit against the steel pipe, and the arc-shaped block is provided with several anti-slip grooves at intervals.

[0015] Preferably, the device further includes a slide rail on which a plurality of frames are movably arranged at intervals.

[0032] The user can directly insert the steel pipe into the notch of the "C"-shaped first rotating frame 2, then activate the second drive mechanism 5 to drive each clamping block 3 to clamp the steel pipe, and then activate the first drive mechanism 4 to drive the first rotating frame 2 to rotate, thereby driving the steel pipe to rotate. In this method of fixing steel pipes, when welding the two ends of a long steel pipe, it is not necessary to insert one end of the steel pipe halfway before fixing it. Instead, the steel pipe can be directly inserted into the notch of the "C"-shaped first rotating frame 2, which reduces the distance that the user has to lift the steel pipe and improves work efficiency.

[0033] Reference Figure 3 and Figure 4 The first drive mechanism 4 includes a first drive gear 401 and a synchronization component 402.

The clamping block 3 has a protruding locking post 302 on its surface. The second rotating frame 501 has an arc-shaped groove 50101 coaxially arranged around it, corresponding to each locking post 302.

By activating the drive assembly 502, the second rotating frame 501 is driven to rotate. Then, through the cooperation of the locking post 302 and the arc groove 50101, each clamping block 3 is driven to reciprocate towards the axis of the first rotating frame 2, thereby clamping the steel pipe.

[0041] Reference Figure 6 The drive assembly 502 includes a rotary motor and a second drive gear 50201. An outer ring tooth 50102 is coaxially arranged around the outer side of the second rotating frame 501.
