Embodiment Construction

[0068] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0069] Such as figure 1 and figure 2 As shown, the first aspect of the present invention provides a mobile catenary wrist arm support structure rotation adjustment device, which at least includes a column 1, the column 1 has a dumped state, a vertical state or the column 1 can be tilted and vertical switch between the two states; figure 1 is a schematic diagram of the column 1 in a vertical state, ...

Abstract

The invention relates to a mobile overhead line system cantilever supporting structure rotation adjusting device and an operation method, the mobile overhead line system cantilever supporting structure rotation adjusting device comprises a stand column, the stand column has a toppling state and a vertical state or can be switched between the toppling state and the vertical state, and a rotation adjusting mechanism is directly or indirectly arranged on the stand column; the stand column and the rotation adjusting mechanism can rotate relatively; and the cantilever supporting structure is directly or indirectly arranged on the rotation adjusting mechanism. When the stand column is switched between a toppling state and a vertical state, the electric conductor is driven by the cantilever supporting structure to gradually ascend or descend basically in a horizontal state. By the adoption of the cantilever supporting structure, the defects in the prior art can be effectively overcome, and in the tilting or erecting process of the cantilever supporting structure, the carrier cable and the contact line keep relatively constant tension; the contact line and the carrier cable are not bent in the moving process; the cantilever structure does not deform after being pulled; and the carrier cable contact line can also ascend or descend in a manner of being relatively parallel to the ground.

Description

technical field [0001] The invention belongs to the technical field of mobile catenary, and in particular relates to a rotating adjustment device and an operation method for a wrist arm support structure of a mobile catenary. Background technique [0002] The existing railway freight loading and unloading station needs to use the gantry crane to lift the goods. In order to avoid touching the mobile catenary during the loading and unloading process, the existing technology adopts the method of directly dumping the column, but the current method has the following shortcomings: [0003] 1. The angle at which the column is tilted is the angle at which the wrist arm will also be tilted. Due to construction errors such as mechanical structure installation and temperature between the columns, there is uneven tension between the columns. [0004] 2. In the prior art, the upright column directly drives the arm and arm topple over, and the pulling force on the catenary cable and the ...
