Abstract

The invention relates to an electric chassis truck which comprises a frame, a positioning mechanism, a motor, a transmission mechanism, a nut gear, a screw rod, an in-place push block, a test position auxiliary switch driving lever, a work position auxiliary switch driving lever, a test position auxiliary switch, a work position auxiliary switch, an operation in-place prompting mechanism and an electric chassis truck position indicating mechanism. The in-place operation prompting mechanism comprises a sliding bent plate, a sliding convex block, a pressing convex block, a spring and a convex block positioning pin. The sliding convex block and the pressing convex block interact to enable the pressing convex block to be lifted, and the pressing convex block can rapidly rebound and make a click sound under the action of the spring after passing through the highest point. A position indication board is provided with two stay wires which are respectively connected with the test position auxiliary switch driving lever and the work position auxiliary switch driving lever, and synchronously indicates the position of the electric chassis truck. The electric chassis truck is additionally provided with an in-place prompting function and a position indicating function, so that the situation that manual operation is not in place or misoperation occurs can be effectively prevented, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of electric chassis vehicles, 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...
