Description

Attached pole self-elevating device

technical field

The utility model belongs to the field of erecting poles and towers for power transmission line construction, in particular to an attached self-elevating device for holding poles.

Background technique

During the construction of transmission line towers, due to the narrow construction environment such as mountains and hills and poor transportation conditions, it is difficult for heavy-duty tower lifting equipment to enter the site. The attached light-duty pole has small overall volume, light weight, simple operation and convenient transportation, which can meet the needs of UHV tower construction at the present stage, and can fundamentally solve the construction problem of pole tower assembly in a narrow space.

In the tower construction, when the tower material of a working face is assembled, it is necessary to lift the pole. It is a common construction method to use mechanical winching to lift and hold poles. Using this method requires that the ground anchor of the outer stay wire of the pole should be located on the extension line with an angle of 45° to the center line of the foundation, and the distance from the center of the foundation should not be less than 1.2 times the height of the tower. When the site cannot meet the requirements, the force of each part must be checked and special safety measures must be taken. Since UHV towers are generally large in size and high overall, once they are located in areas with complex terrain, it will be very difficult to set up the ground anchor burial position. In addition, there are a large number of tools such as pulleys, wire ropes, and shackles that need to be used when lifting the pole, and the arrangement and operation are cumbersome and complicated.

If the above-mentioned pole lifting method is used according to the tower assembly process of the attached pole pole, four groups of pole poles need to be arranged and operated, and the construction efficiency and safety will become very low.
