Closed type combined trolley conductor device suitable for poor working condition

Abstract

The invention relates to a closed type combined trolley conductor device suitable for a poor working condition. The closed type combined trolley conductor device comprises a rail (1) and a current collector (2), conductive bands (1c) are arranged in the rail (1), the current collector (2) comprises a shell body (2a) and conductors (2b) arranged on the shell body (2a), an opening is formed in the lower end of the rail (1), flanges (1d) are arranged on the two sides of the upper portion of the opening, and two folio sealing soft bands (3) are arranged on the opening of the rail (1). The sealing soft bands (3) are respectively attached to the lower end of the current collector (2) tightly at the contact position of the rail (1) and the current collector (2) and the position, stretching out of the opening of the rail (1), of the lower end of the current collector (2). The opening of the rail (1) is sealed by the two folio sealing soft bands (3) at the position, separated from the current collector (2), of the rail (1). The device blocks dust, oil, vapor and the like, carries out blocking protection on the interior of the guide rail, and has the good protection function on the current collector.

Description

technical field [0001] The invention relates to the electrical field, and more specifically relates to a closed combined trolley line device suitable for harsh working conditions. Background technique [0002] Due to the movement, the mobile device needs to constantly change its position. In each different position, the mobile device must be able to obtain power at any time, otherwise it cannot continue to move. At this time, the sliding contact line came into being. The trolley line is also called the driving trolley line and the safety trolley line. It is used to supply power to moving equipment, and consists of two parts: slide wire guide rail (fixed part, connected to the power supply), collector (sliding part, which can slide on or inside the slide wire rail and contact the copper bar to take electricity, current collectors are used to connect with mobile motors). If it is subdivided, the trolley line device is composed of three main parts: sheath, conductor, receive...

AI Technical Summary

Problems solved by technology

In order to solve the problem of high temperature and high pressure, the rigid body sliding contact line is generally used, and its temperature resistance is still limited, and the physical size of the rigid body sliding contact line is relatively large.

Therefore, due to the limitations of the existing trolley line technology, many schemes that can greatly simplify the structure by using mobile power supply methods cannot be implemented.
