Problems solved by technology
In actual operation, when a steel pipe rod with a smaller diameter is nested in a steel pipe rod with a larger diameter, the nesting and pulling process is very difficult due to the friction between the pipe walls. Friction will greatly wear the galvanized layer on the surface of the steel pipe
The above-mentioned traditional operation method is relatively cumbersome, not only easy to wear the steel pipe, reduce the bearing capacity of the steel pipe, but also increase the difficulty of construction

Embodiment Construction
[0032] The substantive content of the present invention will be described in detail below in conjunction with the embodiments, but the protection scope of the present invention is not limited thereto. The experimental operations not described in detail in the experiment are routine experimental operations well known to those skilled in the art.
[0033] Such as figure 1 and 2 The self-adaptive flexible sliding support for steel pipe nesting is shown, which is formed by flexible connection of several support units, and is used for nesting, unloading and transportation of round steel pipes. figure 1 and 2 Among them, 1 is round steel pipes with different diameters, and 2 is the support unit.
[0034] The structure of a single support unit is as Figure 3-8 As shown, it includes a bearing plate 3 and a universal pulley 5 fixed below the bearing plate 3 , and a rubber pad 4 is fixed above the bearing plate 3 . The two sides of the bearing plate 3 are provided with connecting ...

The invention discloses a self-adaption flexible sliding support for nesting steel tubes. The self-adaption flexible sliding support comprises several support units, and the adjacent support units are connected rotatably and are arranged between two nested steel tubes; every single support unit comprises a bearing plate and a universal slide wheel fixed below the bearing plate, and the two sides of each bearing plate are provided with connecting side plates which are used for being rotatably connected with the bearing plates on adjacent support units. The provided self-adaption flexible sliding support can effectively reduce abrasion of nested steel tubes and can effectively improve the loading and unloading and transport efficiency of the nested steel tubes, the support units are flexibly connected, and thus the self-adaption flexible sliding support is high in flexibility and is applicable to steel tubes with different diameters. Through this flexible connection method, disassembly is also conducted conveniently, and support units of different quantities can be combined for use according to needs.
Description
technical field [0001] The invention belongs to the field of transmission line construction safety, and in particular relates to an adaptive flexible sliding support for steel pipe nesting. Background technique [0002] Steel pipe poles are widely used in lines with various voltage levels of 220kV and below due to their advantages such as high strength, small footprint, beautiful shape, low wind pressure, high rigidity, and full play of material properties. However, in order to save space and improve transportation efficiency during stacking and transportation, the method of nesting steel pipes is often used. [0003] During the segmental transportation of the steel pipe rods, due to the different diameters of the steel pipe rods, the smaller diameter steel pipe rods are often nested in the larger diameter steel pipe rods, so as to reduce the number of trucks / ships required for transportation. In actual operation, when a steel pipe rod with a smaller diameter is nested in a...
