As shown in fig. 1 to 9, the present application designs a converter transformer pushing and shifting device, wherein a converter transformer is fixed on a converter transformer carrier 4, and wheels of the converter transformer carrier 4 are arranged in two rows and arranged on two rows of tracks; each rail is provided with a rail clamping device, each rail clamping device is provided with a bidirectional hydraulic transmission system, and the first end of a hydraulic cylinder 3 of the bidirectional hydraulic transmission system is connected with a body 1-1 of the rail clamping device; the second end of the hydraulic cylinder 3 of the bidirectional hydraulic transmission system is connected with the converter transformer carrier 4 through a connecting piece 6.
The rail clamping device is arranged on the rail 2 and has directionality, and the tapered channel of the body 1-1 of the rail clamping device is arranged in a mode that the tapered end direction 1-3A is close to the hydraulic cylinder 3 of the bidirectional hydraulic transmission system, and the non-tapered end direction is far away from the hydraulic cylinder 3 of the bidirectional hydraulic transmission system.
When the device is used, the distance between the two holders 1-2 is adjusted, so that the two holders 1-2 are arranged on two sides of the track 2 (the rail clamping devices 1-2 do not clamp the track at the moment), the hydraulic cylinder 3 of the bidirectional hydraulic transmission system is started to perform bidirectional extension, because the rail clamping devices 1-2 do not clamp the track at the moment, the converter transformer and the bearing vehicle 4 thereof stand still due to the self gravity of the converter transformer, the hydraulic cylinder 3 of the bidirectional hydraulic transmission system drives the body to move on the track 2 towards the extending direction of the hydraulic cylinder, the rail clamping device body 1-1 is pushed along the belt top to move on the track 2 towards the direction far away from the converter transformer bearing vehicle 4, so that the tapered channel 1-3 and the two holders 1-2 perform relative movement, and because the tooth tips of the clamping teeth 1-4 on the surface of the holders 1-2 face towards the non-tapered, the clamping teeth 1-4 are caused to obstruct the clamps 1-2 from moving towards the non-tapering direction of the tapering channel and keep still, so that the rail clamp body 1-1 gradually approaches to the two clamps 1-2, the tapering channel 1-3 in the rail clamp gradually decreases, the tapering channel wall of the rail clamp body 1-1 tends to be attached to the clamp inclined wall, at this time, the clamps 1-2 are clamped and fixed on both sides of the rail 2, therefore, when the two clamps 1-2 approach to the tapering end direction 1-3A of the tapering channel in the tapering channel, the clamps 1-2 can be clamped on both sides of the rail 2, and therefore, the rail clamp 1 of the present application achieves the purpose of clamping the rail 2. Because the rail clamping device 1 is clamped on the rail 2, one end of the hydraulic cylinder 3 of the bidirectional hydraulic transmission system in the direction close to the rail clamping device 1 cannot extend, and one end of the hydraulic cylinder 3 of the bidirectional hydraulic transmission system in the direction close to the converter transformer carrying vehicle 4 continues to extend to drive the converter transformer carrying vehicle 4 to move on the rail 2 in the direction close to the converter transformer carrying vehicle 4, the purpose of pushing and moving of the converter transformer pushing and moving device is achieved.
