A mobile platform for inspection and maintenance of cylindrical steel structures

Abstract

The invention discloses a mobile platform for inspection and maintenance of a cylindrical steel structure, which mainly relates to the field of automation equipment, including a fuselage, a controller, and a drive bearing mechanism for an inspection device; the fuselage includes mutually hinged machine Body 1 and Fuselage 2. A driving motor and a secondary reducer are arranged inside the fuselage. The output gears of the secondary reducer are two. The two output gears are provided with a planet carrier, and a planet carrier is used between the two planet carriers. Articulated connection; the overhauler driving bearing mechanism includes a rodless cylinder and a linear guide rail. The mobile platform of the present invention can be adsorbed on the surface of the steel structure, and can walk on steel structures with different diameters, and can span the nodes of the steel structure; at the same time, it can carry equipment with different functions according to needs, and the equipment can do linear motion on the guide rail, expand The scope of work is improved; the power supply of the present invention is externally connected, and the pneumatic guide rail uses gas as the medium, which reduces the self-weight of the mobile platform and increases the load-bearing capacity of the mobile platform.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a mobile platform for inspection and maintenance of cylindrical steel structures. Background technique [0002] Cylindrical steel structure is a structure composed of steel materials. It is one of the main types of building structures and is widely used in buildings, railways, bridges and residences. Most of the steel structures work in semi-outdoor or open-air environments, such as high-speed rail steel structure stations, canopies, and railway bridges. Due to the influence of sunlight, atmosphere, and rain, it is easy to cause rust and corrosion of the steel structure, resulting in the surface of the steel structure being damaged. Coating powdering, cracking, bubbling, falling off, etc., will bring safety hazards to railway transportation. [0003] At present, the steel structure inspection and maintenance of high-speed rail is mainly based on the combination of manual work...

Problems solved by technology

Most of the steel structures work in semi-outdoor or open-air environments, such as high-speed rail steel structure stations, canopies, and railway bridges. Due to the influence of sunlight, atmosphere, and rain, it is easy to cause rust and corrosion of the steel structure, resulting in the surface of the steel structure being damaged. Coating powdering, cracking, bubbling, falling off, etc., will bring safety hazards to railway transportation

[0003] At present, the steel structure inspection and maintenance of high-speed rail is mainly based on the combination of manual work and small mechanical equipment. The construction requires construction personnel to use the "skylight time" of high-speed rail operation to concentrate on inspection and maintenance, and high-altitude climbing operations are required. Problems such as high labor intensity, bad working environment, low efficiency and poor maintenance effect

With the widespread use of cylindrical steel structures, traditional maintenance methods can no longer meet the requirements of use, and automatic maintenance needs to be realized
