Abstract

The invention discloses a high-voltage board safety door. The high-voltage board safety door comprises a blocking rod arranged in front of a door body and used for preventing the door body from being opened. The high-voltage board safety door further comprises an installation plate arranged on one side of the door body, a lock cylinder fixedly connected with the outer side of the installation plate and an interlocking rod covering plate connected with one end of the blocking rod, wherein the installation plate is provided with a U-shaped groove used for supporting the blocking rod; the interlocking rod covering plate is arranged on the outer side of the installation plate and the lock cylinder and fixedly connected with the installation plate; the interlocking rod covering plate is provided with a key hole through which a key used for opening the lock cylinder can penetrate; the interlocking rod covering plate is provided with a bent edge, and the bent edge is provided with a spring bolt hole through which a spring bolt of the lock cylinder can penetrate. In addition, the invention discloses a locomotive comprising the high-voltage board safety door. According to the high-voltage board safety door, when the door body is opened, the key is still located on the lock cylinder, and therefore the key is prevented from being lost or damaged.

Description

technical field [0001] The invention relates to the technical field of rail locomotives, in particular to a safety door for a high-voltage cabinet. The invention also relates to a locomotive with the safety door of the high-voltage cabinet. Background technique [0002] With the continuous development of my country's rail industry, the market demand for locomotives with various types of high-voltage cabinet safety doors is increasing. [0003] At present, in various AC transmission locomotives in my country, such as HXD1B, HXD1C, HXD1D, HXD1 locomotives, etc., the safety door interlocking installation method of the high-voltage cabinet is to install the lock on the lock rod; when the high-voltage cabinet needs to be opened for maintenance and repair of the equipment in the cabinet , use the key to open the safety lock and take off the safety interlock lever. Since the safety lock and the key have an interlocking function, the key cannot be taken out from the safety lock afte...
