Description

In the present invention, when the vehicle is denied passage, the blocking rod is extended horizontally to block the passage of the vehicle, and when the vehicle is permitted to pass, the tip of the blocking rod is rotated upward or in the traveling direction of the vehicle. It relates to a vehicle blocking device that is moved to allow the passage of a vehicle.

Conventionally, as an example of using a vehicle blocking device for an automatic toll collection system for toll roads (hereinafter referred to as "ETC system"), the one shown in Patent Document 1 is known. In this vehicle blocking device, the blocking rod (1) that denies or permits the passage of the vehicle includes a long bag (10) filled with air. Therefore, even if the vehicle collides with the blocking rod (1), the blocking rod (1) is not damaged and the vehicle is not damaged.
However, in this vehicle blocking device, air may escape from the blocking rod (1) due to changes in temperature or long-term use. In such a case, the blocking rod (1) had to be filled with air by a manual or electric inflator, which was not only time-consuming but also troublesome for maintenance. On the other hand, it is conceivable to adopt the vehicle blocking device shown in Patent Document 2 for the ETC system. According to this vehicle blocking device, air is instantaneously supplied to the arm (6) by the compressor built in the compressor box (9), so that it is considered that it is easy and the time can be shortened.

Embodiments 1 and 2 in which the vehicle blocking device according to the present invention is embodied in an ETC system on a highway will be described below with reference to the drawings. FIG. 1 is a schematic view showing a state in which the vehicle blocking device of the first embodiment is incorporated in the ETC system. As shown in FIG. 1, a pair of vehicle blocking devices are provided on both sides of the ETC lane toward the vehicle traveling to the tollhouse. The vehicle blocking device has a blocking rod 1 and a blocking device 2 for rotating the blocking rod 1. The two blocking rods 1 extend so as to face each other in the horizontal direction when the vehicle is blocked, and the tip of the two blocking rods 1 is indicated by an arrow when the vehicle is allowed to pass. Rotate upward to allow the passage of vehicles. The blocking rod 1 is composed of a long bag body 10 filled with air by compression and a support member 15 that supports the bag body 10. The support member 15 is fixed to a drive shaft 21a of a servomotor 21 (see FIG. 3), which will be described later, provided in the blocking machine 2 at the base end portion. Therefore, when the drive shaft 21a rotates, the blocking rod 1 rotates. Further, the blocking machine 2 is provided with a filling device 3. The filling device 3 makes it possible to fill the bag body 10 of the blocking rod 1 with air via the air hose 8.

As shown in FIG. 2, the bag body 10 is a hollow long columnar shape of a resin sheet, and a filling port 10a is provided at a base end portion. Air can be compressed and filled in or removed from the bag body 10 from the filling port 10a. Further, the support member 15 includes a support member main body 16 and a support cylinder 17.

The base end portion of the bag body 10 is detachably attached to the support cylinder 17, and the drive shaft 21a is fitted to the shaft hole 16a so as not to be slidable and rotatable.

As shown in FIG. 3, the blocking device 2 includes a substantially rectangular parallelepiped housing 20, a control device built in the housing 20, a drive circuit, and the like. In this embodiment, a servomotor 21 with a speed reducer is adopted as this control device. The servomotor 21 is attached to the housing 20 by projecting the drive shaft 21a into which the shaft hole 16a is fitted from the housing 20. Further, a filler 3 is attached to the surface of the housing 20. The filling device 3 is connected to the filling port 10a of the bag body 10 by an air hose 8.

The filler 3 will be described in detail with reference to FIG. As shown in FIG. 4, the filler 3 has a rectangular parallelepiped case 30, an inflator 31, and a pressure regulator 35. The case 30 includes a case body 30a and an upper lid (not shown). FIG. 4 shows a state in which the upper lid of the case 30 is removed. The inflator 31 compresses and fills the bag body 10 of the blocking rod 1 with air, and has a cylinder 32, a piston rod 33, and a spring 34.

The cylinder 32 has a cylindrical shape with an air chamber 32a formed inside, and is provided with an air intake port 32b and an air discharge port 32c at both ends. The piston rod 33 has a rod shape, and the piston 33a is fixed to the base end portion 33d in the air chamber 32a, and the tip portion 33e protrudes from the cylinder 33 through the air intake inlet 32b. The piston 33a has a configuration similar to that of a known one used for a general inflator, and moves in the direction of the air intake port 32b to take in air from the air intake port 32b into the air chamber 32a and also to take in air into the air chamber 32a. It moves in the direction of the discharge port 32c and discharges air from the air discharge port 32c. Further, a spring 34 for urging the piston 33a in the direction of the air intake 32b is wound around the piston rod 33 protruding from the cylinder 32. Therefore, when no load is applied to the piston rod 33, as shown in FIG. 4, the piston rod 33 is raised by the urging force of the spring 34, the piston 33a is pulled up, and air is introduced from the air intake port 32b to the air chamber 32a. Incorporated. Further, when the piston rod 33 is lowered against the urging force of the spring 34, the piston 33a is pushed down and air is discharged from the air discharge port 32c.

At the tip of the piston rod 33, a roller 33c that converts the rotational motion of the blocking rod 1 into the linear motion of the piston rod 33 is provided. With this roller 33c, even if the blocking rod 1 descends while rotating, the piston rod 33 can be reliably lowered.

The pressure regulator 35 keeps the air pressure constant, and is provided in the vicinity of the air discharge port 32c of the cylinder 32. Further, the input port 35a of the pressure regulator 35 and the air discharge port 32c of the cylinder 32 are connected by an air hose 8, and the output port 35b and the filling port 10a of the bag body 10 are connected by an air hose 8. The pressure regulator 35 can prevent the air pressure of the bag body 10 of the blocking rod 1 from rising more than necessary even if the piston rod 33 frequently moves up and down and a large amount of air is discharged from the air discharge port 32c. can.

The operation of the vehicle blocking device having the above configuration will be described with reference to FIGS. 5 and 6. If no vehicle is moving towards the tollhouse, the blocking bar 1 is horizontal, as shown in FIG. At that time, the cylinder 33 is pushed down because the piston rod 33 is lowered via the roller 33c by being pressed by the blocking rod 1. Then, when the vehicle enters the ETC lane and the ETC system permits the vehicle to pass, the servomotor 21 is driven and the drive shaft 21a rotates. As a result, as shown by the arrow, the blocking rod 1 rotates its tip upward about the drive shaft 21a. Then, as shown in FIG. 6, the blocking rod 1 becomes vertical and the vehicle can pass through. At this time, the piston rod 33 is in a no-load state, the piston rod 33 is raised by the urging force of the spring 34, the piston 33a is pulled up, and air is taken into the air chamber 32a from the air intake port 32b.

Then, when the vehicle passes, the servomotor 21 is driven and the drive shaft 21a rotates. As a result, as shown by the arrow, the blocking rod 1 rotates its tip downward about the drive shaft 21a. Then, the blocking rod 1 becomes horizontal and returns to the state shown in FIG. 5, blocking the passage of the vehicle. At this time, the piston rod 33 is lowered against the urging force of the spring 34, the piston 33a is pushed down, and air is discharged from the air discharge port 32c. The discharged air passes through the air hose 8 via the pressure regulator 35 and is filled into the bag body 10 from the filling port 10a. However, the pressure regulator 35 is adjusted so that the air pressure on the output port 35b side does not exceed a predetermined pressure. In this way, each time the vehicle passes through the tollhouse, the blocking rod 1 rotates to fill the bag body 10 with air from the inflator 3.

According to the vehicle blocking device of the first embodiment, the blocking rod 1 has a long bag body 10 having a filling port 10a capable of compressing and filling gas. Further, a filling device 3 capable of filling the bag body 10 with gas from the filling port 10a by rotating the blocking rod 1 is provided. Here, when the vehicle blocking device allows the passage of the vehicle, the tip of the horizontal blocking rod 1 is rotated upward to allow the passage of the vehicle. Then, when the vehicle passes, the blocking rod 1 is rotated and returned to the horizontal position. Therefore, every time the vehicle blocking device permits the passage of the vehicle, the blocking rod 1 rotates and the bag body 10 is automatically filled with gas, and the gas escapes from the bag body 10 due to a change in temperature or the like. Even when it is started, the blocking rod 1 can surely keep its outer shape and is easy to maintain. Further, in this vehicle blocking device, since it is only necessary to add the filler 3 to the existing vehicle blocking device, not only is it compact and inexpensive, but it does not affect the configuration of the entire system and the control method. Therefore, according to this vehicle blocking device, the blocking rod 1 can be automatically filled with gas, which is compact, inexpensive, and easy to maintain.

Further, in this vehicle blocking device, the filling device 3 for filling the filling port 10a of the bag body 10 with air is provided in the blocking device 2 with an inflator 31 and a pressure regulator 35.

It has a piston rod 33 protruding from 32 and a spring 34 for urging the piston 33a in the direction of the air intake 32b, and the piston rod 33 is pressed by the rotation of the blocking rod 1. Therefore, every time the vehicle blocking device permits the passage of the vehicle, the blocking rod 1 rotates and air is discharged from the air discharge port 32c, and the bag body 10 of the blocking rod 1 is automatically filled with air. Further, since the air discharge port 32c and the filling port 10a are connected by the air hose 8 via the pressure regulator 35, even if the vehicle frequently passes and the piston rod 33 is repeatedly pressed, the inside of the blocking rod 1 is formed. The air pressure is kept constant.

Further, in this vehicle measure device, the tip of the piston rod 33 is provided with a roller 33c that converts the rotational motion of the blocking rod 1 into the linear motion of the piston rod 33, so that the rotation of the blocking rod 1 causes the rotation of the blocking rod 1. The piston rod 33 can be reliably operated. In the first embodiment, the filling device 3 is provided on the outside of the housing 20 of the blocking machine 2. However, a cam is attached to the drive shaft 21a in the housing 20 to mount the filling device 3 on the housing 20. It can also be installed inside the.

Next, the vehicle blocking device of the second embodiment will be described with reference to FIGS. 7 to 9. The vehicle blocking device of the second embodiment is also used by being incorporated in the ETC system as in the first embodiment. Further, the same reference numerals will be used for the same configurations as those in the first embodiment, and the description thereof will be omitted. FIG. 7 is a schematic view showing a state in which the vehicle blocking device of the second embodiment is incorporated in the ETC system. As shown in FIG. 7, the filling device 4 is provided on the support member 15 of the blocking rod 1, and the filling device 4 and the bag body 10 of the blocking rod 1 are connected by an air hose 8. Other configurations and operations are the same as those in the first embodiment.

8 (1) and 8 (2) are partially enlarged front views when the rotation of the blocking rod 1 is stopped. FIG. 8 (1) is a case where the blocking rod 1 is horizontal, and FIG. 8 (2) is a case where the blocking rod 1 is vertical. As shown in FIGS. 8 (1) and 8 (2), the filler 4 compresses and fills the bag body 10 of the blocking rod 1 with air, and has a cylinder 40, a piston 41 with a weight, and a spring 42. ing. The cylinder 40 has a cylindrical shape with an air chamber 40a formed inside, and is provided with an air intake port 40b and an air discharge port 40c at both ends. The weighted piston 41 is slidably housed in the air chamber 40a, moves in the direction of the air intake port 40b, takes in air from the air intake port 40b into the air chamber 40a, and moves in the direction of the air discharge port 40c. Air is discharged from the air discharge port 40c. The spring 42 is provided between the air discharge port 40c side of the air chamber 40a and the weighted piston 41, and urges the weighted piston 41 toward the air intake port 40b. Therefore, when centrifugal force is not applied to the weighted piston 41, the weighted piston 41 is pressed in the direction of the air intake port 40b by the urging force of the spring 42, and air is taken into the air chamber 40a from the air intake port 40b. Will be. The air discharge port 40c and the filling port 10a of the bag body 10 are connected by an air hose 8.

FIG. 9 is a partially enlarged front view when the blocking rod 1 is rotating. When the blocking rod 1 is rotating, when the centrifugal force due to the rotation of the blocking rod 1 is stronger than the urging force of the spring 42, the piston 41 with a weight presses in the direction of the air discharge port 40c as shown in FIG. Then, air is discharged from the air discharge port 40c. Further, when the rotation of the blocking rod 1 is stopped, the piston 41 with a weight is pressed in the direction of the air intake port 40b by the urging force of the spring 42, and air is taken into the air chamber 40a from the air intake port 40b.

The operation of the vehicle blocking device having the above configuration will be described with reference to FIGS. 7 to 9. If there are no vehicles moving toward the tollhouse, the blocking bar 1 is horizontal, as shown in FIG. 8 (1). At that time, the piston 41 with a weight is pressed in the direction of the air intake port 40b by the urging force of the spring 42, and the air chamber 40a is filled with air. Then, when the vehicle enters the ETC lane and the ETC system permits the vehicle to pass, the servomotor 21 is driven and the drive shaft 21a rotates. As a result, as shown by the arrow in FIG. 7, the blocking rod 1 rotates its tip upward about the drive shaft 21a. When the blocking rod 1 rotates, as shown in FIG. 9, the piston 41 with a weight is pressed in the direction of the air discharge port 40c against the urging force of the spring 42 by the centrifugal force due to the rotation of the blocking rod 1. , Air is discharged from the air discharge port 40c. The discharged air passes through the air hose 8 and is filled into the bag body 10 from the filling port 10a.

Then, as shown in FIG. 8 (2), the blocking rod 1 becomes vertical and the vehicle can pass through. At this time, the rotation of the blocking rod 1 is stopped and no centrifugal force is applied to the weighted piston 41. Therefore, the weighted piston 41 is pressed in the direction of the air intake port 40b by the urging force of the spring 42, and the air intake port is pressed. Air is taken into the air chamber 40a from 40b.

When the vehicle passes, the servomotor 21 is driven and the drive shaft 21a rotates. As a result, the blocking rod 1 rotates its tip downward about the drive shaft 21a. When the blocking rod 1 rotates, as shown in FIG. 9, the piston 41 with a weight is pressed in the direction of the air discharge port 40c against the urging force of the spring 42 by the centrifugal force due to the rotation of the blocking rod 1. , Air is discharged from the air discharge port 40c. The discharged air passes through the air hose 8 and is filled into the bag body 10 from the filling port 10a.

Then, the blocking rod 1 becomes horizontal and returns to the state shown in FIG. 8 (1), blocking the passage of the vehicle. At this time, the rotation of the blocking rod 1 is stopped and no centrifugal force is applied to the weighted piston 41. Therefore, the weighted piston 41 is pressed in the direction of the air intake port 40b by the urging force of the spring 42, and the air intake port is pressed. Air is taken into the air chamber 40a from 40b. In this way, each time the vehicle passes through the tollhouse, the blocking rod 1 rotates and the bag body 10 is filled with air from the filling device 4. The bag body 10 is filled with air when the air pressure of the air discharged from the air discharge port 40c is higher than the air pressure in the bag body 10, otherwise the bag body 10 is filled with air. Will not be done. Therefore, by adjusting the weight of the weight of the piston 41 with a weight and the spring constant of the spring 42, it is possible to adjust the air pressure of the air discharged from the air discharge port 40c so as not to exceed a predetermined pressure. However, a pressure regulator may be connected between the filling device 4 and the filling port 10a of the bag body 10.

In the vehicle blocking device of the second embodiment, the filling device 4 for filling the filling port 10a of the bag body 10 with air is provided in the blocking rod 1, and the piston 41 with a weight is provided with air by centrifugal force due to the rotation of the blocking rod 1. Air is discharged from the discharge port 40c. Therefore, every time the vehicle blocking device permits the passage of the vehicle, the blocking rod 1 rotates and air is discharged from the air discharge port 40c, and the bag body 10 of the blocking rod 1 is automatically filled with air. Other actions and effects are the same as those in the first embodiment.
