Embodiment Construction

[0007] combine figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 The details and working conditions of the present invention are described in detail. The three-phase power line 1 is connected to the frequency converter 2. After frequency conversion by the frequency converter, three wires 3 are drawn from the frequency converter 2. Multiple vibrators 5 are connected in parallel on the three wires 3. Three wires 3 in front of each vibrator An AC contactor 4 is connected to it, and an induction coil 14 is set on the three wires 3 in front of each vibrator 5. A fault display control circuit 42 is provided on the induction coil, and a preset is set on the control circuit of the AC contactor 4. Connect and preset breaking control circuit 34. The inverter 2 we use is F1000-G0220T3C. At present, most vibrators use a power supply frequency of 50 Hz, and the frequency of the power supply after frequency conversion reaches 150 Hz, thereby increasing the vibration ...

Abstract

The present invention discloses a vibration source device of high-speed railway track plate, which belongs to the equipment field of manufacturing railway track basic, and is suitable for high-speed railway track plate manufacture. The major technique of the present invention is that: a three phase current line is connected to a transducer; after the frequency is converted by the transducer, threeleads are extracted from the transducer, and a plurality of oscillators are connected in parallel with the three leads; the three leads before each oscillator are connected with an alternating current contactor and an induction coil; the induction coil is provided with a fault display control loop, and a control loop arranged at the alternating current contractor is provided with preset connecting and preset subdivision control circuits. The present invention has the advantages that: the present invention can change the power frequency form 50Hz to 150Hz, improves the oscillation frequency ofthe oscillators, and is able to display automatically the practical running state of the oscillators so as to realize group control of the oscillators; moreover, the oscillators have convenient and firm fixation, and are able to work under the condition of concentrated water vapour.

Description

1. Technical field: [0001] The invention belongs to the field of equipment for manufacturing railway track foundations. 2. Background technology: [0002] The speed of the current trains is constantly increasing, from the original tens of kilometers per hour to the current 200-300 kilometers per hour, and this speed is still increasing. The foundation of the original train track was made of stones, and sleepers were laid on the stones, and the track was fixed with spikes on the sleepers, and the train ran on the track. The sleepers were originally made of wood, but now most of them have been made of concrete. This way the train can run, but the speed is not high. With the continuous improvement of transportation technology, especially when the speed of the train increases to more than 350 kilometers per hour, This kind of track foundation made of stones and sleepers is not suitable. The track foundation directly causes the vibration of the train. The better the track founda...
