Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is further described.
Shunting switch controller is made up of headstock 1 and 2 two parts of control chamber, as shown in Figure 1, Figure 2, Figure 3 shows, headstock 1 is positioned at the top of controller, including the belt transmission deceleration system being made up of driving wheel 3 and belt pulley 4, the power shaft 3 of driving wheel 3 and motor is bonded, belt pulley 6 and output shaft 5 key coordinate, and output shaft connects for the control axle with shunting switch.Driving wheel 3 and belt pulley 4 are connected by belt, and are compressed by pinch roller 6.
In the bottom of output shaft, hand-operated gear group is installed, hand-operated gear group is made up of driving gear 7 and driven gear 8, and hand axle is connected with driving gear 7, and handle 9 is arranged on hand axle top, driven gear 8 is arranged on bottom output shaft, it is allowed to rotated by hand mode with to shunting switch.
It is worm structure in the lower section of output shaft 5, by worm gear 11 transmission with by entering to show that axle 12 connects, by entering to show that axle 12 and gear display axle 15 lead gear 13 and shifting gear 14 connects by dialling, by entering to show that axle rotates a circle, stirs shifting gear and rotate a gear.By the angle that the little pointer (see figure 1) entering to show on axle 12 is current for showing output shaft, the pointer on gear display axle 15 is used for showing the number of turns of output shaft rotation.
Being evenly equipped with multiple spacing hole on shifting gear 14, the quantity of spacing hole is identical with the quantity of gear.As it is shown in figure 1, according to the needs of user, initial gear and end gear are configured, the previous spacing hole of initial gear is provided with the first stop screw 16, terminate, on the later spacing hole of gear, the second stop screw 17 is installed.
Shifting gear 14 is arranged above driving lever 18, and the centre rotating shaft of driving lever is arranged on control chamber 2, and lower end is stretched between two stop screws 17, and upper end is stretched between the first fork 19 and the second fork 20；First fork and the second fork are coaxial, and the first fork is positioned at the left side of driving lever, and the second fork is positioned at the right side of driving lever.
Above fork, correspondence is provided with the first push rod 21 and the second push rod 22, and this push rod is arranged in the push rod groove bottom headstock, and push rod groove covers with fixing lid 23, and push rod is cased with spring 24, promotes push rod to move downward, makes the top of push rod not stretch out the bottom surface of headstock.
As it is shown in fig. 7, two limited posts are arranged at the bottom of belt pulley 4, the distance in the two limited post distance belt pulley centers of circle is different, and wherein the first limited post 25 and first push rod 21 of inner side coordinates, and second limited post 26 in outside and the second push rod 22 coordinate.
The minimum gear such as arranging shunting switch is 1 grade, and maximum gear is N shelves, and stop screw is arranged on 0 grade and N+1 shelves.
When shunting switch operate in 1 grade to time between N shelves, dial and lead gear 13 and shifting gear 14 normal rotation, driving lever is between two stop screws, first push rod and the second push rod are by the downward promotion of spring 24, it is in extreme lower position, belt pulley normal rotation, it is achieved gearshift.The angle current by entering the pointer display output shaft showing on axle, the number of turns of the pointer display output shaft rotation on gear display axle.
When shunting switch is in 1 grade, as it is shown in figure 5, the stop screw of 0 gear has contacted driving lever.When belt pulley is rotated further, shifting gear continues to rotate clockwise, and stop screw promotes the bottom of driving lever, making driving lever rotate, the top of driving lever promotes the first fork 19 so that it is rotate clockwise, and then upwardly the first push rod 21, make the top of the first push rod beyond push rod groove.Belt pulley is rotated further, and the first limited post 25 bottom belt pulley and the first ejector pin contact are also stopped by it, stop belt pulley 6 to be rotated further.
Also shown in FIG. 6, when shunting switch is in N shelves, the stop screw of N+1 promotes bottom driving lever, and then the second push rod 22 will rise up, second limited post 26 contacts and stops belt pulley 6 with the second push rod 22 and is rotated further, it is achieved the output shaft mechanical position limitation to shunting switch.
When changing the gear interval of shunting switch, it is only necessary to take off the stop screw on shifting gear, retightening at the spacing hole needed, change arranges very convenient.
