Description

Technical Field

[0001] This utility model relates to the field of pipeline docking technology, specifically a large-diameter pipeline docking platform. Background Technology

[0002] Current pipe connection work typically employs a thermofusion butt welding machine. This process involves first fixing the pipes to the welding machine fixture, then using the thermofusion machine to heat and fuse the two pipe ends. After completion, the thermofusion machine is removed, and a butt welding mechanism is used to press the two pipe ends together under pressure, maintaining this position until cooling and solidification to ensure a tight, bubble-free joint, thus completing the connection. However, large factories often require the installation of large-diameter pipes at heights. Due to the complex spaces and numerous high-altitude operations within factories, coupled with the weight of the pipes themselves, bending and deformation are common during butt welding. Using only a thermofusion butt welding machine is insufficient for accurate butt welding at such heights, impacting precision and construction efficiency. Utility Model Content

[0020] More specifically, the mobile vehicle 1 enables the overall movement of the device. After moving the hot melt butt welding machine 4 to the welding location, the lifting platform 2 is used to lift the hot melt butt welding machine to the position between the two large-diameter pipe ports.

[0021] As a further explanation of this embodiment, the multi-dimensional adjustment mechanism 3 is used to drive the hot melt butt welding machine 4 to perform position fine-tuning, so that the two pipe ports can be accurately inserted into the fixture of the hot melt butt welding machine 4.

[0023] More specifically, a protective rope is hooked between the tops of the two guardrails 23, and a toe board is installed at the bottom of the guardrails 23. The top of the lifting platform 22 is also equipped with a level indicator to determine whether the platform is level before installation.

[0024] As a further explanation of this embodiment, the lifting frame 21 can drive the lifting platform 22 to perform height adjustment, which is convenient for carrying personnel and the hot melt welding machine 4, and assisting in high-altitude pipeline docking work.

[0025] In this embodiment, the multi-dimensional adjustment mechanism 3 includes a base 31; the base 31 is fixed to the top of the lifting platform 22, and a first slide 32 is installed on the base 31; two bidirectional telescopic cylinders 34 are symmetrically distributed on the top of the first slide 32, and the two bidirectional telescopic cylinders 34 are respectively connected to the two sides of the second slide 33; a lifting cylinder 35 is installed on the top of the second slide 33, and the top of the lifting cylinder 35 is connected to the top plate 36.

[0028] In this embodiment, the top plate 36 and the second slide block 33 are connected by a sliding connection, and the second slide block 33, the lifting cylinder 35 and the top plate 36 form a lifting structure.

[0029] More specifically, the lifting cylinder 35 can drive the hot melt butt welding machine 4 to make fine adjustments in the Z-axis direction.

[0030] As a further explanation of this embodiment, guide rods are fixed at the bottom corners of the top plate 36.

[0034] The working principle of the large-diameter pipe docking platform provided by this utility model is as follows: The mobile vehicle 1 enables the overall movement of the device. After the hot-melt butt welding machine 4 is moved to the welding location, the lifting frame 21 can drive the lifting platform 22 to adjust its height. The lifting platform 22 then lifts the hot-melt butt welding machine 4 to a position between the two large-diameter pipe ends, facilitating the support of personnel and the hot-melt butt welding machine 4 for high-altitude pipe docking. Finally, the multi-dimensional adjustment mechanism 3 drives the hot-melt butt welding machine 4 to perform fine-tuning of its position.
