Description

High-speed switching device for a vehicle blocking the bar}

The present invention relates to an opening and closing device for a vehicle blocking bar, and more particularly, to a high speed opening and closing device for a vehicle blocking bar suitable for raising and lowering the blocking bar at a high speed.

In general, a vehicle circuit breaker is installed in an access road for entering and leaving a vehicle, and in the case of a vehicle that is allowed to enter, a switch bar rotates to pass the vehicle through the vehicle and to block the entry of the vehicle in a case where the vehicle is not allowed to enter. to be.

In the conventional circuit breaker, there is a risk that a safety accident occurs as the blocking bar that is lifted high falls down due to gravity. In addition, even when the force is applied from the outside in the closed state does not maintain the state is easily moved downward or upward there is a risk that a secondary accident occurs. As described above, the breaker bar is opened and closed by an opening and closing device. However, after the completion and closing of the breaker, the breaker bar does not maintain its state and cannot be easily moved or maintained by gravity or external force. have.

In addition, in the case of the high-speed breaker operating the breaker bar at high speed, the operating speed of opening and closing the breaker bar is realized at a total time of 0.6 seconds. That is, the quick start section takes 0.15 seconds, the constant velocity section takes 0.3 seconds, and the slow stop section takes less than 0.15 seconds. However, since the capacity of a typical BLCD motor is 100W and the function of the existing controller has a control time of more than 2.0 seconds, there is a limit in that the bar can not be opened and closed at high speed. Therefore, in order to implement an operating speed of 0.6 seconds, a high-performance motor of about 200 to 300W needs to be additionally developed for this controller, and thus there is a problem in that the manufacturing cost is greatly increased.

In addition, in the case of driving the slow stop section, which is the last section when opening and closing the blocking bar in the conventional high speed circuit breaker, at 0.6 seconds, when the blocking bar stops at an operating speed of 0.15 seconds, it does not endure the amount of impact applied to the blocking bar and breaks the blocking bar. There is.

Hereinafter, with reference to the accompanying drawings, a specific embodiment of the present invention will be described the configuration and operation.

1 to 3, the high-speed circuit breaker 100 according to an embodiment of the present invention is a case 10, a rod-shaped blocking bar 20 rotatably connected to one side of the case 10 And a driving means for rotating the blocking bar 20 with respect to the case 10, and a supporting means for supporting the blocking bar raised or lowered by the driving means.

The driving means includes a motor 30 as a driving source, a first link means 34 rotated by the motor shaft 32 of the motor 30, and a rotation shaft on which the first link means 34 is mounted. 36 and a second link means 38 mounted and interlocked with the rotary shaft 36.

The support means includes a stopper 40 mounted on the rotary shaft 36 and interlocked with each other, and first and second cushion springs 42 and 44 provided on both sides of the stopper 40 to elastically cushion the stopper 40. It includes.

In addition, the motor shaft 32 of the motor 30 is connected to the drive cam 52 mounted on the motor shaft 32 and the self-lock means 54 interlocked by the drive cam 52, the self-lock The means 54 are connected to the first link means 34. On one side of the drive cam 52 is provided a position limiting means 56 for limiting the rotation operation of the drive cam 52.

The second link means 38 is fixed at both ends to the second link means 38 at one end thereof, and the other end thereof is fixed to the mechanism inside the case 10 and contracted by the rotation of the second link means 38. The first and second springs 62 and 64 to be expanded are elastically installed.

Operation of an embodiment according to the present invention configured as described above will be described with reference to FIGS. 2, 4 and 5.

2 is a view of the blocking bar in a horizontal state (closed state). In this state, when the blocking bar is raised (opened), when a control signal is generated from a controller (not shown), the motor 30 is driven. The drive cam 52 is interlocked in the counterclockwise direction by the driving of the motor 30, and the self-lock means 54 and the first link means 34 connected to the drive cam 52 are interlocked. At this time, the elastic force pulled by the first spring 62 becomes greater than the braking force of the second spring 62, and the compression repulsion force of the second cushion spring 44 is generated, so that a quick start is faster than the general upward movement of the blocking bar. It becomes possible. As such, the start operation is performed at 0.15 seconds to realize the overall operating speed of the blocking bar at 0.6 seconds.

FIG. 4 illustrates a section in which the force of the first spring 62 and the second spring 64 in equilibrium state is applied to the blocking bar while the blocking bar is raised. Up to this section, the blocking bar 20 is moved at a constant speed by the motor 30, and 0.3 seconds is required among the total operating speed of 0.6 seconds.

5 shows a state in which the blocking bar is completely raised. The drive cam 52 is no longer rotated by the position limiting means 56, and at the same time, the blocking bar 20 is also locked by the self-locking means 54. However, since the operation of the moment when the blocking bar 20 is vertical is made in 0.15 seconds, a load is generated in the braking force of the motor 30. The braking force of the first spring 62 is greater than the second spring 64 while the load generated at this time is controlled by the slow stop motion by the pushing force of the first cushion spring 42.

As such, the time at which the operation of raising the blocking bar 20 from the start to the end may be completed in 0.6 seconds by the mechanical configuration according to the present invention. This can be realized by the existing commercial motor 100W ~ 150W BLDC motor, and the controller system sold previously.

Therefore, it is possible to realize a more accurate and stable operation speed of the cut-off bar by improving the mechanical structure without employing an expensive motor and controller system.
