Description

Technical Field

[0001] The invention relates to the technical field of water pipe connection, and in particular to a device and method for connecting and processing urban drainage pipes. Background Art

[0002] Seepage and drainage pipes refer to a pipe system used to remove groundwater or surface water. In urban construction, the seepage and drainage system is very important for ensuring the safety of roads, bridges and other infrastructure. Pipeline connection processing is to connect different pipe components to form a complete pipe system.

[0003] The threaded connection between urban metal seepage drainage pipes and connectors is a common connection method. However, in some cases with high water pressure or corrosive sewage, in order to ensure the sealing and waterproof strength of the connection, welding sealing is required after the threaded connection. Welding can make up for the tiny gaps or irregularities in the threaded connection, ensure that the connection is completely sealed, prevent sewage or rainwater from leaking from the connection, and welding can enhance the pressure resistance of the connection, especially in high-pressure environments, to prevent the pipe from loosening due to excessive pressure; at the same time, welding can provide additional protection for pipes that transport corrosive media to prevent the media from corroding the connection.

[0004] During the on-site assembly and connection process of existing pipelines, a large amount of manpower is required to connect the pipelines to the threaded connectors, which is not only prone to cause injuries to workers, but also difficult to ensure that the pipelines and the connectors remain stable during the threaded connection process, making it impossible to quickly and stably thread the pipes. In addition, for T-type connectors, it is necessary to manually move the position of the welding structure multiple times, and then spend time to align and fix the welding structure with the welding position. It is impossible to perform intermittent and continuous circular welding at multiple positions, thereby reducing the welding process efficiency. Summary of the invention

During operation, after the pipe and the connector are threadedly connected, the electric telescopic rod 43 is started to extend outward to drive the connecting component 44 to move closer to one side of the pipe. When it moves to the specified position, the rotating motor 442 is started to drive the bidirectional threaded rod 443 to rotate, so that the front and rear semicircular rings 444 are close to each other and surround the outer wall of the threaded connection between the pipe and the connector.

[0044] In addition, the present invention also provides a method for connecting and processing urban seepage drainage pipes, which is completed by a method for connecting and processing urban seepage drainage pipes, and includes the following steps:

[0045] Positioning and fixing of the connector: the connector is placed on the fixing block 334, and the connector is positioned and limited by the two fixing blocks 334. The telescopic cylinder 332 is started to drive the displacement block 333 to move to one side of the fixing block 334 to position, clamp and fix the connector.

[0046] Pipe feeding and limiting: an external tool moves the pipeline, and through the provided guide plate 22 and guide groove 23, the pipeline is conveniently moved along the guide groove 23 into the position of the U-shaped notch 21, and the U-shaped notch 21 is used to support and limit the pipeline.

[0047] Auxiliary rotation connection: by rotating the rotating handle 242, the connecting shaft is driven to rotate, and the connecting shaft drives the disc 243 to rotate. During the rotation of the disc 243, the linkage rod 244 drives the long block 246 and the sliding block to slide in the trapezoidal slide groove 245. The rubber block 247 on the long block 246 contacts and rubs the outer wall of the pipe, so that the pipe is intermittently rotated and threadedly connected with the connector.

[0048] Positioning, locking and clamping: After the pipe and the connector are threadedly connected, the electric telescopic rod 43 is started to extend to drive the connecting component 44 to move closer to one side of the pipe. When it moves to the specified position, the rotating motor 442 is started to drive the bidirectional threaded rod 443 to rotate, so that the front and rear semicircular rings 444 are close to each other and surround the outer wall of the threaded connection between the pipe and the connector. At the same time, the semicircular clamping rings 4410 are close to each other to clamp and fix the outer wall of the pipe and the outer wall of an interface position of the connector connected thereto, respectively, to ensure the stability of the connection between the pipe and the connector and facilitate subsequent welding. When the electric telescopic rod 43 is extended, the magnet block 453 and the magnetic suction block 455 are moved away. At this time, after the suction is lost, the positioning rod 452 enters the positioning hole 456 for positioning and locking, to ensure the stability of the connecting component 44.

[0049] Multi-position intermittent welding: When the semicircular rings 444 are close to each other and fit together, the positioning rod 447 enters the positioning hole 448 for limiting, and at the same time, the two semicircular tracks 445 are combined into a circle, and the welding head 446 is driven externally to move in a circle within the two semicircular tracks 445, thereby performing circumferential welding on the threaded connection between the pipe and the connector. After welding one of the interfaces, the electric slider 42 moves in the driving track groove 41 to drive the connecting assembly 44 to move its position. Through the provided stabilizing plate 451, when the position is moved, the ball contacts the mounting base plate 1, thereby improving the stability of the movement of the connecting assembly 44. When it moves to the next interface position, the electric telescopic rod 43 drives the locking assembly 45 to lock its position again, and the operation is repeated for welding.
