Problems solved by technology

However, there are the following problems in actual operation: the tension of the wire in the construction of the tight hanging line needs to pass through the traction system (namely: wire clamp, shackle, traction wire rope, steering block, hoist drum and wire rope sleeve of fixed hoist, shackle) and ground anchors, etc.) to the ground at last, and the tension of the wire is even as high as 3,4000 N.

Embodiment Construction

[0029] For ease of understanding, combined here Figure 1-5 , the concrete structure and working mode of the present invention are further described as follows:

[0030] like Figure 1-2 Shown, pulling method of the present invention actually comprises the following steps:

[0031] 1), with the side of the tension tower a at the tail end facing the straight tower as the inner side and the opposite side as the outer side, the hoist 10 is arranged outside the tension tower a at the tail end;

[0032] 2), set the steering block; the top pulley 21 of the steering block is fixed on the cross arm of the tension tower a at the tail end through a connecting piece such as a steel rope sleeve or a connecting fitting, and the bottom pulley 22 of the steering block is fixed by a fixing frame or the like at the tower body of the end tension tower a;

[0033] 3), set the main wire gripper 30 and the auxiliary wire gripper 40, first pass the wire b through the auxiliary wire gripper 40, s...

Abstract

The invention belongs to the technical field of transmission line engineering construction, in particular to a wire end pulling method used for transmission line hanging line construction. The invention comprises the following steps: 1) arranging a winch; 2) arrange a steering block; 3) arrange a main wire card device and a sub wire card device; 4) arrange a hauling rope; 5), arrange that auxiliary rope, finish the wire tightening and hang operation. The invention can avoid the wire running because of the anchor of the wire tightening and hanging traction system or the loosening of the jaw ofthe wire clamp in the wire pulling and placing process, so as to ensure the normal construction efficiency and improve the construction safety, thereby facilitating the effective development of the wire tightening and hanging construction operation of the transmission line.

Description

technical field [0001] The invention belongs to the technical field of power transmission line engineering construction, and in particular relates to a method for pulling the end of a wire used in the construction of tight-hanging lines of power transmission lines. Background technique [0002] Tight hanging wire is an important process in the wire construction of transmission line. In the wiring construction of transmission lines, after the conductors are deployed, each tension section is usually used as a construction unit for tight hanging lines. Each tension section includes tension towers at the head and tail ends for fixing the two ends of the wires and a straight tower between the two tension towers for erecting the wires. In each tension section, it is often crossed with other running power lines, communication lines, expressways and high-speed railways. During the erection construction of transmission lines, these crossed power lines, communication lines, expressw...
