Guide rail unit used on transmission tower and guide rail

Abstract

The invention provides a guide rail unit used on a transmission tower and a guide rail. The guide rail unit is of a profile structure, and the guide rail unit used on the transmission tower comprises a rack (10), a left guide rod (20) and a right guide rod (30); the left guide rod (20) and the right guide rod (30) are mutual mirror images, a first inserting hole (21) and a second left side inserting hole (22) are formed in the left guide rod (20), and a first sealed cavity (23) is further contained in the left guide rod (20); and according to the guide rail unit used on the transmission tower and the guide rail, the guide rods and the rack are designed to be of an integrated profile structure, the problem that strength of the connecting position of an existing guide rail unit steel framework is insufficient is well solved, assembly errors are reduced, a whole frame body has no obvious weak points, the whole strength is higher, machining precision of the fixed-length guide rail unit is easily controlled, and scale production is facilitated.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular to a guide rail unit used on a power transmission iron tower, or a guide rail formed by connecting the guide rail units. Background technique [0002] There are three types of lifting equipment used on large-scale transmission towers in my country's electric power industry: shaft elevators, construction elevators and iron tower climbing machines. This type of lifting equipment needs to be operated by a fixed guide rail unit, so the guide rail unit must be installed on the iron tower as a fixed facility. Due to the heavy weight of the equipment, the guide rail unit is generally cumbersome and its own structure, the guide rail unit has a great impact on the safety of the iron tower, which indirectly limits the use of lifting equipment in the power industry. [0003] The application of guide rail unit frames of lifting equipment such as shaft elevators, construction elevato...
