Description

Technical Field

[0001] The utility model relates to the technical field of electric power pipes, in particular to an electric power pipe which is easy to weld. Background Art

[0002] MPP power pipes are made of modified polypropylene as the main raw material. They are resistant to high temperature and external pressure and are suitable for medium and low voltage transmission line cable pipes below 10KV. During on-site installation, the joints of the power pipes need to be welded. However, when MPP pipes are connected through welded parts, their welding stability is poor, which makes it easy for MPP pipes to shake during welding.

[0003] Chinese patent CN 218838694U discloses an MPP pipe that is easy to weld. The method comprises the following steps: passing one end of the MPP pipe body through a stabilizing seat, and then rotating a screw cap on the top of the stabilizing seat, so that the screw cap drives the threaded rod at the bottom thereof to rotate in a threaded hole provided in the stabilizing seat, thereby driving a rotating plate in the arc-shaped stabilizing plate to move synchronously, and then, through a threaded connection between the threaded rod and the threaded hole, the threaded rod drives the arc-shaped stabilizing plate in the receiving groove to move synchronously during the downward movement of the threaded rod, so that the bottom of the arc-shaped stabilizing plate contacts the top of the MPP pipe body. The cooperation between the stabilizing seat and the arc-shaped stabilizing plate effectively prevents the MPP pipe body from shaking during welding. However, during on-site welding, the end of the power pipe may be uneven due to transportation squeezing and the like, and the end of the power pipe needs to be cut and adjusted, which is difficult for the MPP pipe that is easy to weld to adapt to. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an electric power pipe that is easy to weld to solve the above-mentioned technical problems.

[0005] An electric power pipe convenient for welding comprises a pipe body, one end of which is connected to a symmetrical No. 1 extension rod, the No. 1 extension rod is provided with a No. 1 connection block, the No. 1 connection block is slidably connected to the extension block in a transverse direction, the extension block is slidably connected to a support sheet in a longitudinal direction, the support sheet is fixedly connected to a screw rod, and the screw rod is threadedly connected to a nut;

[0006] The other end of the tube body is connected to a symmetrical No. 2 extension rod, which is provided with a No. 2 connecting block, which is provided with a channel. After the No. 2 connecting block abuts against the adjacent extension block, the support plate slides downward until the screw rod abuts against the bottom end of the channel, and the nut abuts against the outer wall of the channel on the opposite side of the extension block.

[0007] Furthermore, the No. 1 connecting block is provided with an auxiliary channel, the extension block is fixedly connected with an auxiliary screw, and the auxiliary screw passes through the auxiliary channel and is threadedly connected with an auxiliary nut.

[0008] Furthermore, the extension block is provided with an L-shaped guide piece, and the vertical surface and the bottom surface of the second connecting block are in contact with the adjacent L-shaped guide piece.

[0009] Furthermore, the width of the channel is smaller than the outer diameter of the nut.

[0010] Furthermore, a non-slip head is provided at the top of the extension block, and a limiting plate is provided at the top of the screw rod.

[0011] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects of the utility model include:

[0012] 1) The second connecting block abuts against the adjacent extension block, and the ends of the two adjacent pipe bodies are aligned and abutted. The support sheet is slid downward until the screw rod abuts against the bottom end of the channel, and the nut is screwed. The nut and the extension block abut against the outer wall of the channel on both sides of the channel, so that the two adjacent pipe bodies are in a stable abutment state, which is convenient for welding. At the same time, the horizontal sliding connection between the extension block and the first connecting block can adapt to the on-site cutting adjustment;

[0013] 2) The No. 1 extension rod and the No. 2 extension rod keep a distance between the No. 1 connecting block and the No. 2 connecting block and the pipe body, so as not to hinder welding in terms of operating space. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The other end of the tube body is connected with a symmetrical No. 2 extension rod 7, which is provided with a No. 2 connecting block 8, and the No. 2 connecting block 8 is provided with a channel 9. During welding, the support sheet 4 is slid upwards so that the position of the screw rod 5 is higher than the top of the channel 9, and the No. 2 connecting block 8 abuts against the adjacent extension block 3, so that the end of the tube body is aligned and abutted with the end of the adjacent tube body, and the support sheet 4 is slid downwards until the screw rod 5 abuts against the bottom end of the channel 9, and the nut 6 is screwed. The nut 6 and the extension block 3 abut against the outer wall of the channel 9 on both sides of the channel 9, respectively, so that the two adjacent tube bodies are in a stable abutment state, which is convenient for welding. The No. 1 extension rod 1 and the No. 2 extension rod 7 keep a distance between the No. 1 connecting block 2, the No. 2 connecting block 8 and the tube body, which will not hinder welding; the No. 1 extension rod 1 and the No. 2 extension rod 7 can be welded at the corresponding position of the tube body, and can also be detachably connected to the tube body through the clamp structure, so that they can be removed and reused after the tube body is welded;

The lateral sliding connection between the extension block 3 and the No. 1 connecting block 2 can adapt to on-site cutting adjustments.

The auxiliary nut and the nut 6 are butterfly-shaped, which is easy to screw without the help of a wrench.

[0026] The extension block 3 is provided with an L-shaped guide piece 12 , and the vertical surface and bottom surface of the second connecting block 8 abut against the adjacent L-shaped guide piece 12 to assist the second connecting block 8 to align with the adjacent extension block 3 .
