Description

Technical Field

[0001] The utility model relates to the technical field of chassis vehicles, in particular to a double-confirmation electric chassis vehicle. Background Art

[0002] In order to enable the center-mounted vacuum circuit breaker to easily realize the functions of pushing in (pushing from the test position to the working position and locking) and withdrawing (withdrawing from the working position to the test position and locking), an electric chassis is generally used to carry the vacuum circuit breaker and realize the pushing in and withdrawing of the vacuum circuit breaker. The existing electric chassis has poor safety protection. The chassis can be operated even when the cabinet door is open. It does not have a corresponding interlocking mechanism and there is no indication whether the chassis is in the unlocked state, which makes it not intuitive to use. In view of this, the existing chassis is improved and optimized. Utility Model Content
