Intelligent handcart switch operating device with alarm function

Abstract

The invention discloses an intelligent handcart switch operation device with an alarm function, which comprises a frame body, a bidirectional threaded rod, an oil drum and a second air bag, and is characterized in that sliding grooves are formed in the left and right inner walls of the frame body, a double-shaft motor is mounted below the inner side of the frame body, and the outer side of the lower part of the bidirectional threaded rod is connected with an oil drum through a bearing; electromagnets are fixed to the upper inner wall and the lower inner wall of the oil drum, first telescopic rods penetrate through the outer side of the oil drum in a sealed mode, supporting plates are movably hinged to the tail ends of the first telescopic rods, steel rings are welded to the outer sides ofthe supports, tires are installed on the outer sides of the steel rings, and a servo motor is installed on the rear side of the frame body; and the output end of the servo motor is connected with therotating rod through a coupler. The intelligent handcart switch operating device with the alarm function is provided with a first air bag and a second air bag, the second air bag on the outer side ofthe sleeve is effectively clamped and fixed to the inner side of the clamping groove in the inner wall of the high-voltage cabinet handcart switch after being expanded through extrusion between the first air bag and the front portion of the high-voltage cabinet, and stability is improved.

Description

technical field [0001] The utility model relates to the technical field of handcart switches, in particular to an intelligent handcart switch operating device with an alarm function. Background technique [0002] The handcart switch is generally used in high-voltage switchgear, and the high-voltage switchgear itself is a complete set of switch control equipment. Its composition is mainly composed of circuit breaker room, busbar room and wire room. To close and start, the specific operation is completed through the rotation of the two-way threaded rod to drive the contact and isolation of the moving contact and the static contact; [0003] However, the operating device of the handcart switch still has certain defects, such as: [0004] 1. The existing handcart switch operation method is usually to use the manual rotation of the handle to realize the rotation of the two-way threaded rod. If the handle is manually rotated, the rotation speed of the handle will be uneven, which...

Problems solved by technology

[0007] The purpose of this utility model is to provide an intelligent handcart switch operating device with an alarm function to solve the above-mentioned background technology. The existing handcart switches on the market generally work by manually rotating the handle to drive the two-way threaded rod. , this will cause uneven rotation speed of the crank handle, which will easily cause the crank handle to fall off during the rotation process, resulting in internal combustion and fire due to short circuit, and the existing operating device of the handcart switch in case of emergency In case of emergency, the alarm signal cannot be sent at the first time, which will easily lead to the occurrence of safety accidents, which will bring inconvenience to people.
