Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular, it is a movable support device for the installation of pressure steel pipes. Background Technology

[0002] In modern engineering construction, pressure steel pipes, as an important pipeline material for transporting media, are widely used in various industries such as water conservancy, petroleum, and chemical engineering. To ensure the stability and safety of these pressure steel pipes during installation, specialized support devices are typically used to provide the necessary support force, preventing deformation or damage caused by external pressure or their own weight. Traditional support methods often rely on fixed support structures, which have poor adjustment flexibility and are difficult to adapt to the needs of pressure steel pipes of different diameters and shapes.

[0003] Traditional support devices are designed as fixed structures with pre-defined dimensions and shapes, making them unadjustable for different pressure steel pipe specifications. This is primarily because traditional designs focus on standardized production to reduce costs and simplify operations, neglecting the diverse needs of construction sites. In practical applications, if non-standard-sized pressure steel pipes are encountered, custom-made or replaced support equipment is required, which not only increases costs but may also delay project progress.

The top pad 16 abuts and supports the inner wall of the pressure steel pipe body 1.

[0025] In this embodiment, the inner support base assembly 5 includes an inner support frame 2 disposed at the center of the inner ring of the pressure steel pipe body 1, and an inner support positioning frame 3 disposed around the inner support frame 2 and located within the inner ring of the pressure steel pipe body 1. The inner support frame 2 provides the basic support structure, while the inner support positioning frame 3 helps to accurately position the entire support system, ensuring its stability and improving the overall stability of the support device. This allows for more accurate positioning and support of the pressure steel pipe during installation, reducing the risks caused by inaccurate positioning.

[0026] In this embodiment, at least four inner support rods 4 are provided, and the ends of the four inner support rods 4 away from the inner wall of the pressure steel pipe body 1 are all fixedly installed together with the inner support frame 2.

[0031] Working principle

[0032] This movable support device for installing pressure steel pipes places the inner support base assembly 5 at the center of the pressure steel pipe body 1. The inner support base assembly 5 consists of an inner support frame 2 and an inner support positioning frame 3, allowing the entire support structure to be stably fixed at the center of the pressure steel pipe. Inner support arm assemblies 6 extend outward from the inner support base assembly 5. These inner support rods 4 of the inner support arm assembly 6 are evenly distributed in a circular array and are securely connected to the inner support frame 2 via pads 7 and locking bolts 8, ensuring a stable connection between each arm and the base, while allowing adjustment to accommodate pressure steel pipes of different diameters.

[0033] One end of each inner support rod 4 is connected to a first fixed sleeve 12 and is connected to a second fixed sleeve 14 via a universal joint 13, so that each support arm can be finely adjusted in multiple directions, thereby ensuring that the top pad 16 can fit tightly against the inner wall of the pressure steel pipe and provide uniform support force.

[0034] The connecting rod 15 located at the end of the second fixed sleeve 14 is further connected to the top plate 16, which directly abuts against and supports the inner wall of the pressure steel pipe body 1. The top plate 16 is designed to disperse the pressure applied to the pipe wall and avoid local stress concentration that could cause damage to the pipe wall.

[0035] By adjusting the position and angle of the inner support rod 4, the first fixed sleeve 12, the universal joint 13 and the second fixed sleeve 14, it is ensured that all the top pads 16 can fit and closely contact the inner surface of the pressure steel pipe. Once the ideal support state is achieved, the entire structure is locked with fasteners such as locking bolts 8 to ensure that it remains stable and does not deform during construction.
