A low wind resistance protection device for preventing pantograph from icing

Abstract

The invention discloses a low-wind-resistance protection device for preventing a pantograph from being frozen in the technical field of pantograph maintenance. The low-wind-resistance protection device comprises an installing box. A T-shaped groove is formed in the top of the installing box. Installing plates are fixedly installed on the left side and the right side of the installing box respectively. A polished rod is fixedly installed on the top of the installing box. A storage box is fixedly installed on the side wall of the right side of the installing box and stores a plurality of thermalinsulation plates. A connecting shaft is movably sleeved with inner cavities of the thermal insulation plates. Motors are fixedly installed on the tops of the two installing plates respectively. A rotating shaft is fixedly installed at the output end of each motor. A rotating gear is fixedly installed on the outer wall of a rotating shaft. Long shafts are movably installed on the tops of the twoinstalling plates respectively. The outer wall of each long shaft is fixedly provided with connecting teeth. The rotating gears are meshed with the connecting teeth. By means of the low-wind-resistance protection device, thermal insulation can be carried out when the pantograph is folded, the pantograph is prevented from being frozen at night, the wind resistance is prevented from being too largewhen the pantograph is unfolded, and meanwhile the pantograph can be unfrozen in extreme weathers.

Description

technical field [0001] The invention relates to the technical field of pantograph maintenance, in particular to a low wind resistance protection device for preventing pantograph from icing. Background technique [0002] Electric traction locomotives are installed on the roof of locomotives or motor cars, which obtain electrical energy from the catenary. Pantographs can be divided into single-arm bows and double-arm bows, both of which are composed of slide plates, upper frames, lower arm rods (lower frames for double-arm bows), underframes, bow springs, transmission cylinders, supporting insulators and other components. Double-arm bows, also known as diamond pantographs, were very common in the past, but they were gradually eliminated due to high maintenance costs and the tendency to break the catenary when a fault occurs. In recent years, single-arm bows have been mostly used. The smoothness of the load current passing through the contact surface of the contact wire and th...

Problems solved by technology

[0005] The purpose of the present invention is to provide a low wind resistance protection device for preventing the pantograph from freezing, so as to solve the problem that the pantograph heads are often caused by the cold weather in winter for trains running in the north of my country proposed in the above background technology. In the event of freezing, the pantograph cannot be raised normally and affects the safety of train operation. The present invention aims to prevent the pantograph from freezing at night and prevent the pantograph from being able to work normally the next day by keeping the pantograph warm when it is closed Use, and at the same time in the state of stretching the bow, it will not affect the operation of the locomotive
