Embodiment 1

[0052] Firstly, the lifting frame for installing the uprights of the spanning frame according to the present invention is manufactured.

[0053] As shown in FIGS. 1 and 6 , the lifting frame of the present invention includes an upper lifting frame 1 and a lower lifting frame 2 .

[0054] The upper and lower lifting frames 1, 2 are frame-shaped steel frame structures with one side opening, and the opening side is used for erecting the working surface side of the spanning frame columns 13, 14 usefulness. The frame-shaped steel frame structure is composed of angle steel, which is used to form the uprights, crosspieces and diagonal bracing members of the frame-shaped steel frame structure. At the bottom of the lower lifting frame 2, a spanning frame column turning mechanism 3 is arranged.

[0055] like image 3 As shown, the above-mentioned spanning frame column 13 to be erected is composed of a cylindrical column and a bow-shaped spanning frame 12 fixedly connected to its top. ...

Embodiment 2

[0077] Except that finally, the bottom of the spanning column of the bottom section is fixed on the column installation base 16 fixed on the ground through steel piles, the others are the same as in Embodiment 1, forming the spanning column lifting frame of the present invention.

Embodiment 3

[0079] Except that the roller set is provided with two rows of nylon rollers on each side wall, the distance between the upper and lower rollers of each row of rollers is 0.05m. In addition, except that the gap between each of the nylon rollers and the outer wall of the spanning frame column is 7mm, the others are the same as in Embodiment 1 to form the spanning frame column lifting frame of the present invention.

[0080] The hoisting frame for the crossing column of the present invention is a lifting and hoisting device for the crossing column of the ultra-high voltage transmission line of 220kv and above in the maintenance and construction of the special traffic facility road section, and is used for the crossing frame and the lifting frame. The installation of its columns. Due to the vertical rotation of the spanning frame column by the turning mechanism, there is no translation and sliding, and the lifting of the spanning frame column is by means of the slideway structure...

Abstract

The invention relates to a device and a method for mounting an upright post of a spanning frame. The device comprises an upper lifting frame (1) and a lower lifting frame (2) of a frame-type steel-frame structure and a turnover mechanism (3) used for erecting the upright post of a spanning frame, wherein one side of each of the upper lifting frame and the lower lifting frame is provided with an opening for mounting the upright post and used as an operation side, and the other sides are sealed by steel frames; the turnover mechanism is arranged at the bottom of the lower lifting frame and comprises a lifting frame baseplate (4), an opening-type hinge axis supporting seat (9) fixed on the lifting frame baseplate, a positioning plate (6) and a mounting plate fixedly connected with a hinge axis (8); the hinge axis (8) can be rotatably matched with the opening-type hinge axis supporting seat (9); and the mounting plate can be mounted and fixed on the bottom surface of the upright post of a spanning frame. The lifting frames are used for the maintenance and the construction of transmission lines with 220 kV and higher ultrahigh voltage during spanning specific traffic facility road sections. The upright post of a spanning frame has convenient and labor-saving mounting and erecting operations and accurate and steady erecting position and can effectively prevent the falling of high-altitude high-voltage wires during the maintenance and the construction of the transmission lines, thereby guaranteeing the safety of the maintenance and the construction.

Description

technical field [0001] The invention relates to the field of maintenance and construction of power transmission lines, and more specifically, the invention relates to a device and method for installing a spanning column for maintenance and construction of power transmission lines. Background technique [0002] During the maintenance and construction operation of transmission lines, such as 220kv or above ultra-high voltage transmission lines, if there are transmission line sections crossing some special traffic facilities, such as crossing highways, railways, etc., in order to prevent transmission line maintenance, The fall of high-altitude high-voltage wires during construction will lead to safety accidents. Usually, high-voltage wires are used to span the frame, so that high-altitude high-voltage wires such as transmission lines can be spanned over it. In this way, the fall of high-altitude high-voltage wires and the occurrence of safety accidents during construction can b...
