The invention discloses a rail transit isolation switch pre-embedded fixing device which comprises a pre-embedded internal threaded pipe and a bearing plate, a fixed connecting plate is connected to one side of the bearing plate in the width direction, a movable connecting plate is slidably connected to the outer side, away from the fixed connecting plate, of the bearing plate, and a locking pieceis arranged on the outer side of the movable connecting plate. Kidney-shaped grooves are formed in the surfaces of the fixed connecting plate and the movable connecting plate in a penetrating mode, and locking bolts matched with the internal threaded pipes are arranged in the kidney-shaped grooves; and a press-fitting stud is arranged on the upper surface of the bearing plate in a sliding mode, and a press-fitting nut is installed on the outer side of the press-fitting stud through threads. The beneficial effects are that the position adjustment of the movable connecting plate can be realized, the installation precision of the isolation switch is prevented from being influenced by the pre-embedded precision of the internal threaded pipe, and the installation quality of the isolation switch is ensured; and position adjustment of the press-fitting stud can be achieved, the installation requirements of isolation switches of different sizes can be met, the application range is wide, and the use effect is good.
Description
technical field [0001] The invention relates to the technical field of isolating switch installation, in particular to a pre-embedded fixing device for a rail transit isolating switch. Background technique [0002] Rail transit is a way of transporting people using rail trains. Rail transit includes subways, light rails, aerial rail trains, trams and maglev trains. From the perspective of energy use, most rail vehicles use electric drive, which is low-carbon and environmentally friendly. At present, the power supply mode of rail transit is to supply power to the rail transit catenary from each traction substation through isolating switches. [0003] When installing the isolating switch, it is necessary to make the isolating switch and the power supply network have a certain positional relationship. The current isolating switch mainly adopts the method of bolting first, that is, the foot bolts are pre-embedded when the frame column is poured. However, the pre-embedded pre...
