Description
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to construction equipment and a construction method for a power tower assembly.
Background
There is a lack of efficient, specialized construction machines. A large number of excellent engineering machinery manufacturing enterprises emerge domestically, and the improvement of the construction mechanization level is promoted. For the construction industry of assembling iron towers in power transmission line engineering, the application of efficient and professional construction machinery to carry out mechanized construction is urgently needed. The labor intensity of operators is high, the efficiency is low, the construction period is long, the operation risk is high, and the requirements of environmental protection cannot be fully considered in part of construction modes. With the continuous and rapid development of economic society, the cost of the power grid construction human resources is greatly increased, and particularly, first-line constructors are lacked and wages are continuously increased. Meanwhile, the strong smart power grid puts forward higher requirements on the engineering construction quality and the construction period, the design concept and the method are innovated, the mechanical construction requirements of the whole process of the line are met, the manual investment and the operation risk are reduced, the engineering construction quality and efficiency are further improved, and the economic, environmental and social benefits are improved.
Along with the continuous improvement of transmission line voltage class, the tower shape size of transmission line iron tower is showing to be increased, and tower material singleton weight is big, and the installation accuracy requires highly, and quality control is tight, and the tower construction degree of difficulty increases, has also proposed higher requirement to the tower construction level. Therefore, a reasonable mechanical tower combining mode is selected according to the actual conditions of the combined engineering, and a new schedule is provided for the research, development and utilization of mechanical equipment with stronger universality, better reliability and higher mechanization level.
The mobile crane (including an automobile crane, a full-ground crane, a crawler crane, an off-road tire crane and the like) is key equipment for construction of heavy projects such as metallurgy, wind power, high-speed rail, nuclear power, petrochemical industry and the like, and plays an irreplaceable role in infrastructure. The mobile crane has the advantages of good maneuverability, convenient field transfer and larger hoisting weight, and the mobile crane is a safe and efficient construction method when used for assembling a mobile crane in narrow areas or high towers accessed by transportation roads, is limited by terrain and road conditions, and has less chance of using the mobile crane in iron tower assembly in power transmission line engineering. The mobile crane comprises a crawler crane, a tire crane, an all-terrain crane and a lorry-mounted crane, and various types of the mobile crane have own characteristics and advantages, and are the most commonly used automobile cranes at present. The automobile crane arranges the lifting, amplitude variation, rotation and operation devices on a tyre type chassis, can flexibly run on a road surface, has better maneuverability, but has high requirements on roads and fields, and has the advantages of larger frame, higher gravity center, higher overall height, more various transmission line engineering points, dispersed operation points, poorer road transportation conditions, and the automobile crane is only applied in small ranges such as urban areas, plains and the like. The crawler crane can run under load and has good maneuvering, cross-country and obstacle crossing performances. However, the main arm 55m has a heavy weight (three are taken as examples, the main arm 55m has an SCC800HD self weight of 88t, a counterweight of 27.6t and a transport width of 3.49 m), and the main arm needs to be assembled by a crane on site in a matching way, and can only be applied to areas with less smoke, such as western plateaus, northern plains and the like.
The diversity of the domestic tower assembling construction machine and method adapts to the requirements of different voltage grades and different tower types under different terrain conditions, and the tower assembling method and technology are continuously innovated and perfected in development, thereby playing an important role in ensuring the safety of tower assembling construction and improving the work efficiency. However, the construction of the floor double-flat-arm holding pole tower assembly and the rocker arm holding pole technology are only suitable for pile positions with good terrain and traffic convenience, few domestic application cases exist in high and large mountainous areas and steep terrains due to the adoption of the floor double-flat-arm holding pole and the rocker arm holding pole tower assembly, and the mainstream mode is that the outer stay wire suspension holding pole and the inner stay wire suspension holding pole are disassembled to form the tower. However, in recent years, accidents caused by the use of the suspension holding pole group tower are frequent. Therefore, the development of research and application of key technologies of the novel crawler-type electric construction crane for mountainous terrain is necessary, and the research result can effectively solve the problem that tower assembly is difficult in parts of terrain complex areas.
Therefore, it is necessary to provide a construction apparatus for a power tower and a construction method thereof.
