Power transmission line first-aid repair tower assembly demonstration model

Abstract

The invention relates to a power transmission line first-aid repair tower assembly demonstration model, which comprises a model demonstration table, a hoisting device, a holding pole system, a traction system and a stay wire system, and is characterized in that mounting seats are arranged on the left side and the right side of the front surface of the model demonstration table, supporting columnsare arranged below the mounting seats, and mounting upper plates are arranged below the supporting columns; spring columns are arranged on the left side and the right side below the upper mounting plate, lower mounting plates are arranged below the spring columns, connecting plates are arranged below the lower mounting plates, braking devices are arranged on the right sides of the connecting plates, a hoisting device is arranged above the model demonstration table, and a single-loop model first-aid repair tower is arranged on the left side of the inner side of the hoisting device. A double-loop model repair tower is arranged on the right side of the single-loop model repair tower, and the single-loop model repair tower and the double-loop model repair tower each comprise a lower tower section, a middle tower section and an upper tower section; the product has the advantages that the emergency repair effect is improved, the on-site practical operation effect is improved, and the assembly is convenient.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a demonstration model for erection of power transmission line emergency repair towers. Background technique [0002] Among the power grid equipment, overhead lines are most susceptible to external forces and the influence of nature. Once the overhead line tower overturns, it will not only cause a large-scale power outage, but also it is very difficult to restore power transmission in a short time. At present, in dealing with the tower overturning In emergency repairs, the same kind of spare towers configured in the warehouse are usually used. Although this method can complete the task of emergency repairs to a certain extent, it has many inconveniences in transportation and on-site assembly, and its assembly speed is relatively slow. , the key point is that the tower type of the same kind of spare tower is single, it is difficult to meet the general r...

Problems solved by technology

[0002] Among the power grid equipment, overhead lines are most susceptible to external forces and the influence of nature. Once the overhead line tower overturns, it will not only cause a large-scale power outage, but also it is very difficult to restore power transmission in a short time. At present, in dealing with the tower overturning In emergency repairs, the same kind of spare towers configured in the warehouse are usually used. Although this method can complete the task of emergency repairs to a certain extent, it has many inconveniences in transportation and on-site assembly, and its assembly speed is relatively slow. , the key point is that the tower type of the same kind of spare tower is single, it is difficult to meet the general requirements in emergency repair; due to the high production pressure in recent years, it is difficult to organize a practical drill of using the repair tower to repair the inverted pole. There are many requirements, and the preparation work is cumbersome, time-consuming and labor-intensive. In addition, the number of young workers has gradually increased in recent years, while the number of old workers has decreased year by year. Skills will be lost, and the repairing tower repairing drill model can be practiced on a table, and the personnel in each position can carry out repeated drills, and can improve the ability of young workers to repair poles in a short period of time, and improve young workers' ability to repair The emergency response capability for sudden pole down incidents, so as to ensure the reliability of power supply. At present, the power transmission corona inspection room is not effective in complex practical exercises such as the repair tower assembly, mainly because there are many points in the process of this type of exercise, and attention needs to be paid There are many focuses and concerns, and the training is not in place, which is prone to safety hazards, and the number of large-scale practical trainings such as the repair tower assembly is not many, and the practical experience is insufficient, especially for new employees. It is not conducive to their comprehensive grasp of the assembly process and process requirements of the emergency repair tower; therefore, it is very necessary to provide a transmission line emergency repair tower assembly demonstration model that improves the emergency repair effect, improves the on-site practical operation effect, and is easy to assemble
