Embodiment Construction

[0041] In order to facilitate the public to fully understand and implement this solution, the following explanations and descriptions of preferred implementation modes are made.

[0042] First of all, the proposal of this question is based on a phenomenon of waste of resources discovered by the applicant during the on-site construction operation. Due to bumping, the local damage is caused (because the side edge of the pulley is relatively weak), and the generally damaged part is the side edge 14 on both sides of the pulley groove, which is an irregular shape and the damage rate does not exceed 5% of the pulley, such as figure 1 shown. The filling piece is completely scrapped pulleys with a breakage rate exceeding 5%, such as figure 2 As shown, the completely discarded (damage rate exceeds 5%) pulleys are cut into equal parts and then processed to form filling pieces.

Abstract

The invention discloses a nylon paying-off pulley digging and filling repair method and a repair clamping structure. The nylon paying-off pulley digging and filling repair method and the repair clamping structure are used for solving the repairing problem of a damaged nylon pulley. Firstly, opening digging is conducted on a to-be-repaired pulley, a filling block is prepared, and the filling blockis formed by cutting a same kind of damaged pulley; then high-strength adhesive glue is evenly smeared on the positions of the combination opening of a steel wire and the filling block and a to-be-repaired notch of the to-be-repaired pulley together and the filling block is bonded, and clamping and positioning are conducted on the to-be-repaired pulley and the filling block in the circumferentialdirection by utilizing two sets of axial clamps; and finally the repaired position is polished. According to the nylon paying-off pulley digging and filling repair method and the repair clamping structure, existing resources are fully utilized, nylon pulleys which are damaged in large areas and locally damaged in small areas are fully utilized, new pulleys are formed, and the purpose of turning waste into wealth is achieved.

Description

technical field [0001] The invention relates to a digging repair method for nylon parts used in power transmission and transformation projects, and discloses a clamping and fixing structure used in the method. Background technique [0002] With the development of UHV and EHV power grid construction, tension stringing construction technology has been widely used nationwide. The construction process of tension stringing requires a large number of single-wheel or multi-wheel combination MC nylon pay-off blocks. Its main purpose is to hang on the iron tower as a supporting force-bearing fixed pulley for guidance, ground wires and optical cables for transmission and erection between iron towers. Restricted by the environmental conditions of the construction site, this type of pulley (the diameter of the pulley is between 0.8m and 1.2m) is relatively large in size and weight, and bumps and extrusions are inevitable during transportation and use, which can easily cause the edge of ...
