The invention discloses an electric chassis vehicle, which comprises a frame, a positioning mechanism, a motor, a transmission mechanism, a screw rod, a nut gear fixing base and a nut gear, wherein components of the positioning mechanism cooperate with one another to form an anti-misoperation mechanical interlocking mechanism, a manual operating handle cannot be sleeved in an operating end socket of the screw rod when tongue plates of the positioning mechanism are not inserted into positioning holes of a switch cabinet properly, and the electric chassis vehicle cannot be operated manually; and when the tongue plates of the positioning mechanism are inserted into or withdrawn from the positioning holes of the switch cabinet, a state of an auxiliary switch installed at a corresponding position inside the switch cabinet changes along with the insertion or withdrawal of the tongue plates accordingly, and a control device can judge whether electric chassis vehicle meets an electric operating condition according to the state of the auxiliary switch during electric operation. The electric chassis vehicle realizes the anti-misoperation function of disenabling manual or electric operation when the tongue plates of the positioning mechanism of the electric chassis vehicle are not inserted into the corresponding positioning holes of the switch cabinet properly, and effectively prevents the adverse effect caused by the misoperation.
Description
technical field [0001] The invention relates to an electric chassis vehicle, in particular to an electric chassis vehicle used in a high-voltage switch cabinet. Background technique [0002] With the continuous advancement of the intelligent upgrading and transformation of substations, the application of electric chassis vehicles used to carry vacuum circuit breakers in central switchgears has become more and more widely used, and it has been realized that the vehicle can be electrically completed in the case of "no one" on site. Or out of the car operation. In the prior art, a variety of electric chassis vehicles that can be electrically operated and manually operated have appeared. As the Chinese invention patent CN103280727B discloses an electric chassis vehicle, the screw nut does not move when the electric chassis vehicle is manually operated. The mother turns the screw and does not move. Therefore, the electric chassis vehicle with this structure does not need a clut...
