Upper tower layer structure of cleat-shaped direct-current linear tower

Abstract

An upper tower layer structure of a cleat-shaped direct-current linear tower comprises a tower body, an upper tower layer is arranged on the top of the tower body and comprises a left wing and a right wing, and the left wing and the right wing are symmetrically distributed on the two sides of the tower body; the upper tower layer is provided with T-shaped tracks for an anti-falling device to slide, and the T-shaped tracks are laid along the outermost edge of the upper wing and the outermost edge of a rectangular frame. The T-shaped tracks can reach all the range of the whole tower so that various portions on the tower body structure can be maintained, and using performance of the tower body structure is guaranteed; the T-shaped tracks are installed on the side edges which all the parts pass during extension, and stability is high during installation.

Description

technical field [0001] The invention relates to the field of tower structures, in particular to an upper tower structure of a Yangjiao DC linear tower. Background technique [0002] The pole tower is one of the basic equipment in the overhead distribution line, which is used to support the transmission line in the sky. When installing pole towers and maintaining high-altitude power equipment, staff are required to climb pole towers. At this time, in order to ensure the safety of staff, it is usually necessary to use pole tower fall prevention devices to protect climbing staff from falling. [0003] Traditional anti-fall devices include rail-type anti-fall devices and guide rope-type anti-fall devices; among them, the rail-type anti-fall devices are provided with guide rails on the tower, and self-locking devices are installed on the guide rails, and the other end of the self-locking devices is connected to the staff. The safety cable on the body is fixed, and there is also ...

Problems solved by technology

[0003] Traditional anti-fall devices include rail-type anti-fall devices and guide rope-type anti-fall devices; among them, the rail-type anti-fall devices are provided with guide rails on the tower, and self-locking devices are installed on the guide rails, and the other end of the self-locking devices is connected to the staff. The safety cable on the body is fixed, and there is also a steering gear on the guide rail, so that the rail can be changed and turned when encountering a bifurcation or turning of the guide rail; Used for protection work during the assembly of guide rails

The guide rope type fall prevention device is set up in sections, and the two ends of the multi-section soft lock are respectively fixed on the tower, and are connected with the safety belts on the staff through the fixed parts. Finally, according to the actual situation, the flexible cable is cut and installed on the tower to provide anti-fall protection, and it is also impossible to achieve the anti-fall protection during the erection of the tower.
