Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding equipment for water conservancy engineering pipelines. Background Technology

[0002] Water conservancy projects widely utilize various pipelines to collect, transport, distribute, and regulate water resources. Water conservancy projects are engineering projects constructed to control and regulate surface and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. The construction of water conservancy projects requires the building of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways. These structures control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. The metal pipelines used in water conservancy projects often require considerable length. However, limitations in equipment technology and space during pipeline manufacturing, as well as inconvenience and cost during subsequent transportation, often prevent the required length from being met. Therefore, welding equipment is used to weld the pipelines to meet the length requirements.

[0003] Currently available hydraulic pipeline welding equipment struggles to achieve precise concentric positioning when welding two sets of pipelines, resulting in poor welded pipeline connection quality. This can negatively impact the overall stability and sealing of the pipeline system. Furthermore, the equipment lacks flexibility when welding pipelines of different diameters, failing to make convenient and effective adjustments based on the actual pipe diameter, thus limiting its applicability. Additionally, during the welding process, the welding head cannot maintain a tight fit with the welding surface, leading to incomplete welds and affecting overall weld quality. Summary of the Invention

[0004] This invention relates to a hydraulic engineering pipeline welding device. The rotating frame engages with a fixed ring via a rotating ring groove. A second motor drives a first gear, which in turn drives three sets of double-headed positioning pressure plates inwards via an external gear ring, achieving concentric positioning of the pipeline to improve welding accuracy. The movable frame utilizes sliding holes and threaded holes to engage with the fixed rod and threaded rod of the rotating ring, allowing for position adjustment according to the pipeline diameter. Furthermore, the welding head remains in close contact with the welding surface via a connecting rod and elastic element, preventing incomplete welds. Simultaneously, the first motor drives the rotating ring to rotate via a linkage gear ring and connecting gear, causing the welding head to rotate around the pipeline for welding, thus improving welding efficiency.

[0005] In a first aspect, the present invention provides a welding device for water conservancy engineering pipelines, specifically comprising: a base and a pipeline; A set of connecting gears is rotatably mounted on the base.

Three sets of double-headed positioning plates are slidably mounted on the outer end of the fixed ring. An external gear ring is fixedly mounted on the outer end of the rotating frame. The three sets of first gears are respectively meshed with the external gear rings on the outer end of the rotating frame for transmission. A set of movable frames is threadedly mounted on the outer end of the rotating ring. A set of welding heads is slidably mounted on the movable frames. There are two sets of pipes. The two sets of pipes are placed inside the double-headed positioning plates.

[0009] Furthermore, a set of fixing rods is fixedly installed at the outer end of the rotating ring, and a set of sliding holes are provided on the movable frame, and the sliding holes on the movable frame are slidably installed on the fixing rods at the outer end of the rotating ring.

[0010] Furthermore, a set of connecting plates is fixedly installed on the movable frame. The connecting plates have sliding holes. A set of connecting rods is fixedly installed on the outer end of the welding head, and the connecting rods at the outer end of the welding head are slidably installed on the sliding holes of the connecting plates.

[0011] Furthermore, a rack is fixedly installed on the outer end of the double-headed positioning plate, and the rack at the outer end of the double-headed positioning plate meshes with the outer end of the first gear for transmission.

[0012] Furthermore, a set of elastic elements is also sleeved on the connecting rod, and the elastic elements are in contact with the inner end face of the connecting plate on the movable frame.

[0013] Furthermore, a set of threaded rods is rotatably mounted on the outer end of the rotating ring, and a set of threaded holes are provided on the movable frame, with the threaded holes on the movable frame threadedly mounted on the threaded rods at the outer end of the rotating ring.

[0014] Furthermore, the outer end of the fixed ring is provided with a set of annular grooves, and the outer end of the rotating frame is fixedly installed with a set of rotating rings, and the rotating rings at the outer end of the rotating frame are rotatably installed on the annular grooves at the outer end of the fixed ring.

[0015] This invention provides a welding device for water conservancy engineering pipelines, which has the following beneficial effects: In this invention, the outer end of the rotating frame is mounted on the groove of the fixed ring. The second motor drives the first gear through the external gear ring to make three sets of first gears rotate simultaneously. Then, through the rack and guide block, the three sets of double-headed positioning pressure plates move inward simultaneously, which facilitates the concentric positioning of the two sets of pipes and improves welding accuracy. The moving frame cooperates with the fixed rod and threaded rod of the rotating ring through the sliding hole and threaded hole, respectively. Rotating the threaded rod can make the moving frame and welding head move inward to adapt to the welding of pipes with different diameters.

The guide block on the double-headed positioning plate is slidably mounted on the guide groove at the outer end of the fixed ring, so that the three sets of double-headed positioning plates move inward simultaneously, so that the double-headed positioning plates can easily position the two sets of pipes concentrically and improve the welding accuracy of the device.

[0017] Furthermore, the movable frame is slidably mounted on the fixed rod at the outer end of the rotating ring via a sliding hole. The threaded hole on the movable frame is threaded onto the threaded rod at the outer end of the rotating ring. Rotating the threaded rod allows the movable frame and welding head, which are threaded onto the threaded rod, to move inward easily.
