Abstract

The invention provides an auxiliary device for overhauling the top of a transformer, and belongs to the field of devices for overhauling the transformer. The auxiliary device comprises a bottom plate, wherein electromagnets and a hook are arranged at the bottom of the bottom plate, a power supply is arranged on the top surface of the bottom plate, and the electromagnets are connected to the power supply through a control device; a sleeve is arranged on the top surface of the bottom plate, a horizon bar is arranged, one end of the horizon bar is inserted in the sleeve in a penetrating manner, a hydraulic cylinder is arranged at the other end of the horizon bar, and a seat is arranged on a piston rod of the hydraulic cylinder; an oil pump, an oil tank and an electromagnetic valve are arranged on the bottom plate, two oil ports of the hydraulic cylinder are connected to two connectors on one side of the electromagnetic valve, one of two connectors on the other side of the electromagnetic valve is connected to the oil tank through the oil pump, and the other connector on the other side of the electromagnetic valve is directly connected to the oil tank. Therefore, working staff can safely and conveniently overhaul the top of the transformer, and can find the suspension point of a safety belt.

Description

technical field [0001] The invention provides a transformer top maintenance auxiliary device, which belongs to the field of transformer maintenance devices. Background technique [0002] The height of the top of the transformer is often more than 5 meters from the ground, and the height of the bushing on the top of the transformer is often more than 7 meters from the ground. When the bushing or other equipment on the top of the transformer is overhauled, the safety risk is relatively large. Take the casing as an example: the shape of the casing is cylindrical, and the person needs to ride on the casing when the casing is overhauled. The seat belt needs to be hung high and low), so there is a greater safety risk. Contents of the invention [0003] The purpose of the present invention is to provide an auxiliary device for maintenance on the top of a transformer, so that workers can safely and conveniently perform maintenance and find the suspension point of the safety belt....
