Mutual inductor replacement, loading and transporting auxiliary device

Abstract

The invention discloses a mutual inductor replacement, loading and transporting auxiliary device which comprises a lifting cart and a position fine adjusting device; the lifting cart comprises a cart body, a load platform, a main scissor lifting frame and a driving mechanism for driving the lifting of the main scissor lifting frame, the lower end of the main scissor lifting frame is connected with the cart body, and the upper end is connected with the load platform; The position fine adjusting device is arranged on the top surface of the load platform and comprises a work platform, a lift platform and the like. According to the invention, the device can be used for transporting the mutual inductor and assisting the mounting and dismounting of the mutual inductor, and the device can directly transporting the mutual inductor to a switch cabinet outlet cabin and can coarsely adjust the position of the mutual inductor up and down and finely adjust the position of the mutual inductor forward, backward, left, right, up and down, the device can safely, conveniently, time-savingly and labor savingly implement the mounting, dismounting, transporting, loading and unloading work of the mutual inductor, the labor intensity is reduced, the personal safety of staffs of electrical equipment and maintenance is ensured, and the device has higher popularization and application value than before.

Description

technical field [0001] The invention relates to an auxiliary tool for power supply equipment, in particular to an auxiliary device for transformer replacement and shipment. Background technique [0002] The number of high-voltage switchgears in the power system configuration is huge. Taking a city power supply company as an example (as of April 2017), there are 53 operation and maintenance substations, 1484 high-voltage switchgears, and 4998 transformers in the cabinet. The installation and replacement of transformers in the cabinet are relatively frequent. Due to the small working space and the lack of effective auxiliary devices, the existing working methods are time-consuming and labor-intensive, and the risk factor is extremely high. It is a problem that actually exists and needs to be solved during the maintenance process. . [0003] 1.

Problems solved by technology

The installation and replacement of transformers in the cabinet are relatively frequent. Due to the small working space and the lack of effective auxiliary devices, the existing working methods are time-consuming and labor-intensive, and the risk factor is extremely high. It is a problem that actually exists and needs to be solved during the maintenance process.

[0003] 1. The weight of a single transformer configured in the high-voltage switchgear is about 20 to 150 kilograms. The vehicle transportation requires manpower to load and unload. The process of loading and unloading the vehicle is quite laborious, and there is a danger of hurting people

[0004] 2. On the way to transfer the transformer from the door of the switch room to the lower cabinet door of the switch cabinet to be overhauled, it is necessary to bypass a narrow passage. The surface of the transformer body is smooth and there is no grasping force point. 2 to 4 times of pauses, rests and hand changes are required, which increases the labor intensity of personnel and the complexity of transshipment, and increases the transshipment time

[0005] 3. The outlet compartment of the switchgear is more crowded, and it is difficult for two people to stand in it, and it is very difficult to replace the heavy transformer

It is even more difficult to replace the transformer that is vertical to the ground and suspended on the electrical beam of the rear cabinet of the switchgear. Only 2 people can complete the movement of the transformer into or out of the switchgear, lifting or lowering, aligning the mounting holes, removing or penetrating. In the process of tightening bolts and other processes, if the strength is weak, the hands are sweaty and slippery, or if you are careless, accidents such as personal injury or electrical equipment damage will occur, causing unnecessary losses.
