Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

First, the vehicle blocking gate according to the present invention is similar to a known vehicle blocking gate, and the housing 10 and the housing 10 on the base plate 16 and the base plate 16 formed on the ground of a certain place where the vehicle enters and exits horizontally. The gate bar 200 is connected to block the vehicle.

1, 2 and 5 are internal perspective views showing the components on the upper plate 15 of the housing 10 of the vehicle blocking gate according to the present invention.

As can be seen from Figures 1 and 2, 5, in combination with the gate bar 200, the shaft 20 and the rotation control means and the driving means connected to the horizontally extending in the space in the space on the upper plate (15) Is shown.

The rotation control means refers to the components connected to the shaft 20 on the upper plate 15, the driving means refers to the motor for generating power and the connecting means for supplying the generated power to the shaft 20.

First, before explaining the rotation control means according to the present invention, the shaft 20 is connected uniaxially with the gate bar 200 through the connecting member 40 and the bar bundle provided on the outer peripheral surface of the housing 10. The rotation control means in the coupling order in the inner direction (left to right in FIG. 1) on the shaft 20, the unit bearing 30 and the spring support 60, the spring 70, the limit switch (100, 110) and rotation control It consists of sensors 80 and 90.

The unit bearing 30 bears the load of the gate bar 200 and is disposed between the left end of the upper plate 15, that is, between the gate bar 200 and the connecting rod 50 in order to smoothly rotate the shaft 10. As described above, the unit bearing 30 is also located at the right end of the upper plate 15, that is, between the rotation control sensors 80 and 90 and the spring 70.

The spring 70 provides a constant load to the rotational speed of the motor 140 by its elastic force to adjust the shaking phenomenon when the gate bar 200 is opened. One end of the spring 70 is formed on the spring support 60. It is fixedly attached to the other end is in close contact with the surface of the upper plate (15). Therefore, with the rotation of the shaft 20, the spring 70 affects the rotational speed of the shaft 20 while repeating tightening and loosening.

The limit switch 100, 110 is composed of an up-limit switch 100 and a down-limit switch 110, and these up and down limit switches 100, 110 are formed of the shaft 20. Depending on the degree of rotation is in contact with the up rotation control sensor 80 and the down rotation control sensor 90, respectively. The down rotation control sensor 90 has a hexagonal (or octagonal) shape extending in one direction and the up rotation control sensor 80 is cut in a straight shape to have a flat surface based on a circular shape. It has at least one cut surface in shape. Each of the rotation control sensors 80 and 90 having this shape comes into contact with each of the parallel one up and down limit switches 100 and 110 when the gate bar 20 moves up or down. When the rotation control sensor 80.90 comes into contact with the limit switches 100 and 110, the limit switches 100 and 110 transmit this contact state as a signal to the unit controller 300 to stop the rotation of the motor 140. .

 The upper plate 15 has a bent portion extending vertically from the left and right ends thereof, and the connecting member 40 and the unit bearing 30 are connected to the bent portion, and the upper plate 15 has a flat structure as a whole. The above-described rotation control means is located, in particular in a portion where the connecting rod 50, which is one of the driving means to be described later, to a certain size, that is, the size of the range that does not interfere with the vertical rotation of the connecting rod 50 A rectangular hole 15a is formed, and the connecting rod 50 moves up and down.

Driving means for generating and transmitting power according to the present invention is made of a connecting rod 50 and the crank arm 120, the motor connecting portion 130, the motor 140.

The upper end of the connecting rod 50 is connected to the shaft 20 between the unit bearing 30 and the spring support 60 of the upper plate 50, the motor 140 is provided below the upper plate 15 It is to transfer the power of the () to the shaft 20 is driven in a way to move up and down in the vertical direction of the hole (15a) of the upper plate 15, that is, the top is the shaft 20, the bottom is the crank arm It is connected to 120.

The crank arm 120 is positioned between the motor 140 and the connecting rod 50 to transfer the rotational motion of the motor 140 to the connecting rod 50 and is attached and fixed to the lower end of the upper plate 15. It is connected to the shaft of the motor 140 protruding outward from the inside of the housing of the motor 140, specifically, the motor connecting portion 130 is located between the crank arm 120 and the motor 140.

The motor connection unit 130 includes a motor support 131, a bearing 132, and a bearing arm 133. A round hole is formed in the center portion of the rectangular motor support 131 so that the bearing 132 is positioned and the bearing arm 133 is inserted into the bearing 132, and the motor shaft is connected to the hole of the bearing arm 133. do. In other words, the motor shaft is connected to the crank arm 120 through the bearing arm 133, the bearing 132, and the motor support 131 in the right-to-left direction on the drawing. The motor connection unit 130 serves as a buffer for preventing the crank arm 120 and the motor 140 are directly connected to generate a load on the motor shaft. This structure prevents the motor shaft from being easily damaged.

In the housing 10, a lower side, that is, a lower side of the motor 140, a lighting unit 320 such as a vehicle detecting unit and a light bulb, a known component such as a power switch 310, and a unit controller 300 are located. . This unit controller 300 is responsible for the operation of the gate of the present invention and the known control function by the remote control, as well as supplying the necessary power to adjust the rotation of the motor 140, according to the amount of power ( It is responsible for controlling the rotation of the 140.

The unit controller 300 includes a phase control means (not shown), which is divided into a rising phase control means and a falling phase control means.

When the gate bar 200 is raised and lowered by the rotation of the motor 140, the motor 140 is driven. The rising and falling start time of the gate bar 200 and the starting and falling time points, the rising and Considering the various relations between the end point of falling and the load when the gate bar 200 rises and the load when it descends, if the motor 140 rotates constantly without considering this relationship, the acceleration and the fall Due to the difference in acceleration, there is a difference in speed at the time of rising and falling of the gate bar 200, and the movement of the gate bar 200 is not smooth, and thus, a smooth driving of the gate bar 200 cannot be executed. Can be. In order to overcome this, the phase control means of the unit controller 300 according to the present invention is a phase control element (silicon control rectifier (SCR) (silicon control rectifier) (SCR), preferably US GE's trade name TRAC (bidirectional three-terminal) Silicon controlled rectifier). In other words, by controlling the conduction angle of the waveform of the input voltage transmitted to the motor 140 to subdivide the time when the motor 140 rotates to control the power supplied to each time. Therefore, the rising phase control means and the falling phase control means take into account that the load of the gate bar 200 at the time of rising and the load of the gate bar 200 at the time of falling are different from each other and the number of rotations must also vary according to the motor rotation reduction ratio. Thus, when the rising and falling has a control value for the rotational speed of the different motor 140, and thus the rotational speed of the motor 200 driven at the time of rising and falling of the gate bar 200 two phase control means By managing according to the preset power value in each can lead to the smoothness of the drive of the gate bar 200, and it can also prevent the shaking shape of the gate bar 200 that may occur during the drive.

Hereinafter, the operation caused by the above-described configuration of the present invention will be described with reference to the accompanying drawings.

When the open signal is input to raise (open) the gate bar 200 while the unit controller 300 is powered on, the rising phase control means of the unit controller 300 supplies power preset thereto. do. At this time, as the motor 140 rotates, the crank arm 120 also rotates and transfers a force to the connecting rod 50 connected to the crank arm 120 so that the connecting rod 50 moves. Accordingly, as the shaft 20 is driven, the gate bar 200 starts to rise. The motor connecting portion 130 is positioned between the shaft of the motor 140 and the crank arm 120 to ensure the protection of the motor shaft.

Due to the elastic force of the spring 70, a constant artificial load is supplied to the rotational speed of the motor 140 (or the shaft), thereby additionally adjusting the shaking phenomenon when the gate bar 200 rises. When the gate bar 200 is fully raised to a right angle, the up rotation control sensor 80 comes into contact with the up limit switch 100, and the stop signal by the UP limit switch 100 is transmitted to the unit controller 300. Is transmitted to stop the rotation of the motor 140. As the gate bar 200 rises, the rotation of the motor 140 is divided according to time zones so that the rising phase control means adjusts the rotation speed thereof.

The lowering process of the gate bar 200 is made in the opposite operation, but considers the weight and the acceleration of the lowering of the gate bar 200 and the difference between the rotation speed of the motor 140 when the gate bar 200 rises. In consideration of this point, the lower phase control control means controls the rotation speed of the motor 140 according to a preset rotation speed.

In other words, the number of revolutions of the motor 140 may be controlled by adjusting the amount of electric power by dividing the starting point of the rotation of the motor 140, an operation point, an end point, and the like by the rising and falling phase control adjusting means. Through the fast operation of the gate bar 200 performs a function to prevent the shaking phenomenon and noise phenomenon.

As described so far, the configuration and operation of the vehicle blocking gate according to the present invention have been represented in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. Of course, various changes and modifications can be made without departing from the technical spirit.

As described above, according to the vehicle blocking gate according to the present invention, it is possible to achieve the excellent gate bar up and down action even with a simple configuration, and to extend the life of the motor shaft by configuring the motor connection part for the overload generation of the motor. There is an advantage to this. In addition, the gate bar has a phase control means for subdividing the rising and falling time points during movement of the gate bar to control the rotation speed of the motor according to each time point, so as to facilitate the movement of the gate bar and other components. It has the effect of preventing the shaking and noise phenomenon and to perform a safer and smoother vehicle blocking.
