Centrally-installed switchgear intelligent maintenance dolly

Abstract

Provided is a centrally-installed switchgear intelligent maintenance dolly. The back side of a chassis of the dolly is provided with a support frame; the support frame is provided with a lifting mechanism; the lifting mechanism drives a load-bearing tray to rise or fall; the load-bearing tray is provided with a horizontal adjustment bench; the horizontal adjustment bench is provided with a bearing bench; the bearing bench comprises a bearing platform; a pair of bearing guide rails are fixedly arranged on the bearing platform; each pair of bearing guide rails are connected with slide guide rails; top frame guide rails in front and back direction are arranged on the bearing platform and at the outer sides of the bearing guide rails respectively; the two top frame guide rails are connected with a master slide base and a slave slide base in a movable fit manner respectively; a top frame is fixedly arranged between the master slide base and the slave slide base; the top frame is provided with two grabbing devices; each grabbing device comprises a grabbing rack and a grabbing hand; and the two grabbing racks are respectively and fixedly provided with a visual sensor. The centrally-installed switchgear intelligent maintenance dolly is suitable for being controlled by a computer, is high in automation degree, can save both time and labor, can transfer a circuit breaker in a centrally-installed switchgear to the bearing platform of the dolly safely and reliably, can be suitable for the centrally-installed switchgears of different models and specifications, and is high in adaptability.

Description

technical field

[0001] The invention relates to high-voltage power distribution equipment, which is an intelligent maintenance trolley for central cabinets. Background technique

[0002] With the rapid development of the power grid, the number of 10kV equipment has increased significantly, and the 10kV equipment in many old substations has also been gradually transformed, and the use of central cabinet equipment is becoming more and more extensive. When the circuit breaker in the central cabinet is overhauled, the circuit breaker needs to be pulled out of the cabinet and placed on a special trolley for maintenance and test work. With the increase of the interrupting capacity of the circuit breaker, the self-weight of the circuit breaker body is increasing. It is difficult to move the circuit breaker from the cabinet to the trolley platform by manpower. Not enough, it is necessary to adjust the height of the trolley platform to be consistent with the corresponding height of ...
