Description
Technical Field
The utility model relates to an electric power system device field, more specifically relates to a shaft tower normal position hoisting device.
Background
Pole towers (PoleandTower), rod-shaped or tower-shaped structures that support and maintain a distance between overhead transmission line conductors and overhead ground wires and to the ground. All countries in the world adopt steel construction, timber structure and reinforced concrete structure for line shaft tower. Rod-shaped structures of wood and reinforced concrete are commonly referred to as poles, and steel structures of turriform and reinforced concrete chimney-shaped structures are commonly referred to as towers. The tower without the stay wire is called a self-standing tower, and the tower with the stay wire is called a stay wire tower. China lacks wood resources, does not use wood poles, and has prominent achievement in the aspects of reinforced concrete poles manufactured by applying the centrifugal principle and reinforced concrete chimney-shaped spanning towers. The pole tower is one of basic devices in an overhead distribution line and can be divided into a wood pole, a cement pole and a metal pole according to the used materials. The cement pole has the advantages of long service life, small maintenance workload and the like, and is widely used. The most used concrete rods are tapered rods, the taper of which is generally 1/75, and the tapered rods are divided into common reinforced concrete rods and prestressed reinforced concrete rods.
The tower can be divided into a self-supporting tower and a guyed tower according to the structural form. The self-standing tower is a tower which is stabilized by the foundation of the self-standing tower. The stay wire tower is characterized in that symmetrical stay wires are arranged on a tower head or a tower body to stably support the tower, and the tower only bears vertical pressure. The tower saves steel by about 40 percent, but the stay wires occupy more land, are unfavorable for the machine ploughing of agriculture and forestry, and have limited application range. The guyed tower has good mechanical performance, can resist the impact of wind storm attack and line disconnection, and has stable structure, so that the higher voltage lines are applied more guyed towers. A catenary tower is newly created on a 735 kilovolt line by Quebec in Canada, and the economic benefit is good. When studying lines over 1000 kv, various countries mostly take the tower type as the main object.
As cities develop, transmission demands change, and the specifications and lengths of transmission lines also change. It has become increasingly difficult for towers that are initially erected to meet the requirements for supporting overhead transmission lines. More and longer transmission lines need to be supported and erected, the towers need to be transformed in multiple aspects, the most important one is the transformation aiming at the height of the towers, and the transmission lines can be better supported and erected only when the height of the towers is increased. In cities, land resources are very tight, and new land cannot be provided for the reconstruction of the tower, so that the reconstruction of the tower can be carried out only at the original position without building new infrastructure, and the problem of occupied land does not need to be considered. Then, in order to reduce the engineering quantity and the resource consumption, the tower lifting transformation principle is carried out on the basis of the original tower, so that the engineering quantity can be reduced, and the original resource is utilized to the maximum extent. Finally, all parts of the tower after being transformed are stressed uniformly so as to ensure the safety. Therefore, a high-safety tower in-situ lifting device is needed.
