Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0033] The structures mentioned in the present invention, unless otherwise specified, are conventional methods in the art.

[0034] A double-column suspended frame structure rope export and import method, such as figure 1 and figure 2 As shown, the method adopts a sheave mechanism for the export and import of the rope. The sheave mechanism includes a hanging plate 1 and a sheave 3 that are connected to each other. The hanging plate and the sheave are connected to slide up and down. Can rotate, the sheave is made with one or more than two radial long grooves 2, the ropes that need to be exported and imported are put into the radial long grooves one by one, and the ropes are released from the pay-off block through the forward and reverse rotat...

Abstract

The invention relates to a double-column suspended frame structure rope leading-in method. The method adopts a sheave mechanism to lead the ropes in. The sheave mechanism includes a hanging plate and a sheave connected to each other, and a hanging plate and a groove. The upper and lower sliding parts of the wheel are connected and set. The sheave can rotate. The sheave is formed with one or more radial long grooves. The forward and reverse rotation of the wheel realizes that the rope is exported and imported from the frame of the pay-off block. The sheave mechanism in the present invention can realize the rapid introduction and export of the rope from the fully enclosed tackle frame, avoiding the removal of the pin shaft between the tackle suspension plate and the tackle column at high altitude, and the rope being lifted out or entering the frame and then carrying out the pin shaft. Hole alignment and installation in the air ensure that the block and rope are always under control, which greatly improves the efficiency of high-altitude operations and reduces the safety risks of high-altitude operations.

Description

technical field [0001] The invention belongs to the technical field of power transmission line construction, in particular to a double-column suspended frame structure rope lead-in method and application. Background technique [0002] Relevant national regulations require that power lines of 110kV and above must be wired under tension. Because the tension pay-off has the following advantages: First, it greatly reduces or avoids the damage of the conductor and ground wire. Secondly, reduce or avoid deforestation and destruction of economic crops and agricultural crops. Thirdly, for some special crossings, deep valleys, high mountains, abyss, wide pools, rivers, etc. that are difficult to reach by human release, tension release can be more economically solved. [0003] Before tension stringing, it is necessary to hang the pay-off block, and lay out the primary guide rope, the secondary guide rope in turn, until the main traction rope is laid out, and finally the wire is laid...
