The specific embodiment

Below in conjunction with concrete drawings and Examples the utility model is described further.

As shown in the figure, the utility model is installed in the point of crossing place of first railway line 12 and second railway line 14 of two right-angled crossings.

Shown in Fig. 1～6, cylinder 2 is positioned at a side of first railway line 12, is installed on the fixed frame 1, and the rod end of cylinder 2 is equipped with connector 3, has the driving lever hole on the connector 3, and driving lever 4 upper ends are contained in the driving lever hole and can freely rotate; Driving lever 4 is installed on the end of connecting panel 11, and the other end of connecting panel 11 is fixed on the end of swing-around trajectory 9; Swing-around trajectory 8 is fixed on rotating disk 5 tops, and the bottom at rotating disk 5 centers is axis of revolution 8 fixedly, is set with thrust ball bearing 7 on the axis of revolution 8, and described rotating disk 5 and swing-around trajectory 9 mounted thereto are pressed on the head bearing circle of thrust ball bearing 7; Thrust ball bearing 7 is assemblied in the bearing seat 6, and bearing seat 6 is by being bolted on the fixed frame 1.

In addition, first travel switch 13 and second travel switch 15 are installed also on the described fixed frame 1, they lay respectively at a side of cylinder 2 piston rod mobile routes, and when cylinder 2 piston rods were withdrawn fully, first travel switch 13 was touched in driving lever 4 lower ends; When cylinder 2 piston rods stretched out fully, second travel switch 15 was touched in driving lever 4 lower ends; Described first travel switch 13 and second travel switch 15 can be used to judge whether swing-around trajectory 9 is rotated in place.

As Fig. 5, shown in Figure 6, the four direction on the described fixed frame 1 is equipped with the short rails 10 that can dock mutually with swing-around trajectory 9 by bolt respectively, and wherein two short rails 10 are positioned on first railway line 12, and two other is lacked rail 10 and is positioned on second railway line 14.

During concrete the application, initial condition of the present utility model as shown in Figure 5, the piston rod of cylinder 2 contracts fully in cylinder body, the two ends of swing-around trajectory 9 respectively with second railway line 14 on two short rails 10 dock mutually, constituted second track of a connection.Simultaneously, driving lever 4 lower ends touch first travel switch, 13, the first travel switches 13 and send signal, and the track that indicates this moment connects situation.
