Platform car for installation of isolating switch mechanism

Abstract

The invention relates to a platform car for the installation of an isolating switch mechanism, which comprises a platform mechanism, a car frame mechanism and a lifting mechanism, wherein a transversely moving mechanism of the platform mechanism is installed on a bracket through a longitudinally moving mechanism; two upright posts and a back wheel frame of the car frame mechanism are fixed on a car frame, two front wheels are installed on side beams through a front wheel shaft, two back wheels are connected with the back wheel frame through a back wheel shaft and a back wheel bracket, and flexible brake blocks are installed on the back wheel bracket; an adjusting bracket of an adjusting component is installed on two side beams and a back beam, and an adjusting screw rod on a chassis is screwed in a screw hole of the adjusting bracket; and two bearing seats of the lifting mechanism are respectively installed on an end plate and the back beam, two ends of a lifting screw rod which is screwed on a screw nut seat are respectively installed on the two bearing seats through bearings, an L-shaped worm seat is connected with the end plate, and a worm wheel which is connected with the lifting screw rod is meshed with a worm which is installed on the worm seat. The platform car of the invention can conveniently adjust the installation position of the isolating switch mechanism, can be used safely and reliably, and can improve the installation accuracy and the installation efficiency.

Description

technical field [0001] The invention relates to a platform vehicle used for installing an isolating switch mechanism, and belongs to the technical field of auxiliary tools for installing electrical equipment. Background technique [0002] As one of the important equipment in the power system, the isolating switch is mainly used to create an obvious disconnection point during equipment maintenance, so as to isolate the equipment under maintenance from the operating equipment. In the current power system, the isolation switch mechanism in the 110-500kV substation is very common. With the continuous increase of the grid load and the oil-free transformation of the circuit breaker, the reliability of the isolation switch directly affects the work of the grid system. reliability and safety. However, general-purpose auxiliary tools are used in the installation and maintenance of the isolating switch mechanism. Especially when the knife switch box is installed, it needs to be adjus...

Problems solved by technology

However, general-purpose auxiliary tools are used in the installation and maintenance of the isolating switch mechanism. Especially when the knife switch box is installed, it needs to be adjusted according to the installation position on site. Not only is the operation very inconvenient, the construction efficiency is low, and the installation accuracy is not easy to guarantee, which will cause Affect the sensitivity of the operating mechanism of the disconnector and the reliability of use
