Abstract

The invention discloses a crossing device for a power transmission line. The device comprises a crossing frame, and a base is arranged at the lower end of the crossing frame. The base comprises an inserting sleeve, a mounting plate, a support frame, a rotating device, lifting legs and a connecting piece. A rotating device connected with the support frame is arranged in the support frame, and the mounting plate is arranged at the upper end of the rotating device, wherein one end of the mounting plate is connected with a rotating device through a connecting piece, and the mounting plate is connected with the rotating device through a first threaded rod. The lifting legs are arranged at the two sides of the mounting plate, and the inserting sleeve is arranged on the upper end face of the mounting plate. An inserting column is arranged at the lower end of the crossing frame and is connected with the inserting sleeve. The base is of an angle-adjustable type, so the problem that time and financial resources are consumed for inclined reconstruction of the spanning frame is solved after construction. The base can be fixed according to the terrain, thereby solving the problem that the ground needs to be firstly leveled when the terrain is uneven, and saving a large amount of manpower, material resources and financial resources.

Description

technical field

[0001] The invention relates to the technical field of construction of power transmission lines, in particular to a spanning device for power transmission lines. Background technique

[0002] When the transmission line is arranged overhead, sometimes it needs to cross the expressway, railway, transmission line, etc., so it is necessary to build a spanning frame, and set up a protective net between the spanning frames. The transmission line passes above the protective net, and through the protective net. Protection when laying out transmission lines.

[0003] The construction period of the spanning frame is relatively long. Generally, the height of the spanning frame can reach about 10-30m. The base of the spanning frame is fixed. If it is found that the frame is tilted when crossing the frame, it is difficult to adjust, and it has to be rebuilt, which is very labor-intensive and time-consuming; and when the ground is uneven, the ground needs to be dug and la...
