Here, the coupling member 30a and the coupling hole 22a are rotatably coupled through the coupling member 50 and the coupling member 30b and the coupling hole 22b through the bush 51. The gear shaft 23 is inserted into and fixed to the inside of the bush 51.

The roller 24 is made of a soft material such as rubber. The roller 24 supports the blocking plate 20 on the main body lower plate 11 when the blocking plate 20 is lowered, and the wheels of the vehicle when the blocking plate 20 is operated upward. By rotating in conjunction with the vehicle is to prevent the ride over the unmanned breaker (1).

The gear shaft 23 is rotationally driven in the forward or reverse direction by the drive unit 40 provided in the main body 10.

5 is an enlarged perspective view illustrating main parts of the driving unit 40 in an enlarged manner.

In FIG. 5, the driving unit 40 is coupled to the air cylinder 41, the cylinder rod 41a of the air cylinder 41, and the rack gear 42 reciprocating together with the cylinder rod 41a, and the rack gear. And a pinion gear 43 engaged with the 42 and driven to rotate in accordance with the reciprocating movement of the rack gear 42, and a gear wheel coupled to the drive gear 43 and a worm wheel on the gear shaft. It is comprised with the driven gear 44 provided with 44a). Here, the drive gear 43 is coupled to the driven gear 44 at a constant gear ratio to rotate the driven gear 44 at an appropriate speed when the cylinder rod 41a is operated.

In particular, a tool engaging portion 44b is formed above the gear shaft of the driven gear 44 to insert and engage a tool for manually rotating the driven gear 44, such as a wrench. The through hole 45a is formed also in the upper side of the box 45 so that a tool can be inserted from the outer side. The through hole 45a communicates with the communication groove 22a provided in the blocking plate 20 as described with reference to FIG. 1.

In addition, the cover 46 is installed while covering the gear box 45 and the air cylinder 41 as a whole.

Next, the operation of the unmanned circuit breaker having the above-described structure will be described.

The unmanned circuit breaker is installed in a parking area for parking a vehicle. First, the installer places the unmanned circuit breaker 1 on the ground of the corresponding parking area, moves the blocking plate 20 of the unmanned circuit breaker 1 upwards, and then installs the unmanned circuit breaker 1 by using a fastening member. do.

When the vehicle to be parked enters the parking area in the state where the unmanned circuit breaker 1 is installed, although not shown in the drawing, for example, the vehicle detector detects the arrival of the vehicle and transmits the vehicle detection signal to the control means.

After receiving the vehicle detection signal from the vehicle detector, the control unit counts a predetermined time required for parking and when the time elapses or when the driver confirms the parking intention by pressing the parking button of the fare checker installed in the parking area, Air is injected into the air cylinder 41 of the breaker 1 to operate the air cylinder 41.

When the cylinder rod 41a of the air cylinder 41 is moved and pulled outward in the longitudinal direction, the rack gear 42 is moved in the same direction. Then, the drive gear 43 is rotated accordingly.

When the drive gear 43 rotates, the driven gear 44 geared to the drive gear 43 rotates according to the gear ratio, and accordingly, the worm wheel 44a provided on the gear shaft of the driven gear 44. ) Will rotate.

When the worm wheel 44a rotates, the worm gear 22 and the gear shaft 23 coupled thereto rotate. As described above, the gear shaft 23 is fixedly coupled to the coupling hole 22b of the blocking plate 20 through the bush 51, and the blocking plate 20 is connected to the main body 10 through the coupling member 30. ) Is rotatably coupled. Therefore, when the worm gear 22 is rotated by the rotation of the worm wheel 44a, as shown in FIG. 6, one side of the blocking plate 20 is rotated upward from the main body 10 with the fastening member 50 as the central axis. do.

The blocking plate 20 is set such that the height from the ground to the highest point at the time of rotation is, for example, about 290 mm. The highest height of the blocking plate 20 is taken into consideration of high-rise vehicles such as RV cars or trucks. Of course, the maximum height of the blocking plate 20 will be appropriately set in consideration of the height of the vehicle to be parked.

When the blocking plate 20 is rotated upward and the upper surface of the blocking plate 20 contacts the bottom of the vehicle, upward blocking of the blocking plate 20 is no longer possible. That is, the operation of the cylinder rod 41a of the air cylinder 41 is forcibly stopped. When the cylinder rod 41a is forcibly stopped while the air is being supplied to the air cylinder 41, negative pressure is generated in the air cylinder 41.

When the negative pressure in the air cylinder 41 becomes more than a predetermined level, the control means cuts off the air supplied to the air cylinder 41 according to the detection signal from the internal pressure sensor as usual. As a result, the blocking plate 20 is held in a stopped state in contact with the upper side of the bottom of the vehicle, as shown in FIG. 7.

On the other hand, when the vehicle driver withdraws the vehicle in a lawful manner, for example, when the parking fee is normally paid, the control means recovers air from the air cylinder 41. Therefore, in this case, the cylinder rod 41a is operated in the opposite direction to the operation of the blocking plate 20, that is, toward the air cylinder 41 side, whereby the drive gear 43 and the driven gear 44 operate the blocking plate. The blocking plate 20 is rotated downward by rotating in the reverse direction to the hour.

When the lowering of the blocking plate 20 is completed and the pressure of the air cylinder 41 becomes less than a predetermined level, the control means stops the air extraction of the air cylinder 41. In this state, the vehicle driver can leave the vehicle outside the parking space.

On the other hand, when the driver forcibly leaves the vehicle while the blocking plate 20 is operated upward, the vehicle moves with the engine force, and the driving wheel is brought into contact with the roller 24 of the blocking plate 20. If the driving wheel of the vehicle is set to park through the unmanned circuit breaker 1, the roller 24 rotates at the same speed even if the driving wheel is rotated, so that the vehicle cannot cross the blocking plate 20. do. That is, when the blocking plate 20 is operated, it is impossible for the driver to release the vehicle without permission.

In addition, when the driver tries to forcibly press the blocking plate 20 downward by using an external force, the rotational force of the worm gear 22 mounted on the gear shaft 23 is applied to the worm wheel 44 in the vertical direction. Since the worm gear 22 is not rotated. That is, the blocking plate 20 is prevented from being forcibly rotated downward by an external force.

On the other hand, in the unmanned circuit breaker 1 having the above-described structure, when the breaker plate 20 is rotated downward, that is, in the non-operational state, if a breakdown or the like occurs in the breaker 1, the breaker 1 is broken. It is difficult to repair. That is, as described above, since the blocking plate 20 is driven through the combination of the worm wheel 44 and the worm gear 22, the blocking plate 20 is rotated upward or downward by an external force without driving the worm wheel 44. It is impossible. Therefore, in case of failure of the unmanned circuit breaker 1, there is a demand for a method of easily rotating the blocking plate 20 upward for repair of the internal device.

As illustrated in FIG. 1, a communication groove 20a is provided at an upper side of the blocking plate 20, and the communication groove 20a is a tool engaging portion 44b above the driven gear 44 as described in FIG. 5. In communication with. When the tool is inserted into the unmanned circuit breaker 1 through the communication groove 20a to be coupled to the tool coupling portion 44b and the tool is rotated, the driven gear 44 rotates together with the worm wheel 44a. As a result, the blocking plate 20 is rotated upward while the worm gear 22 rotates.

At this time, after the blocking plate 20 is rotated upwards by a predetermined period or more, the blocking plate 20 is operated by putting a hand into the space between the blocking plate 20 and the unmanned circuit breaker 1 to operate the cylinder rod 41a. It can be easily rotated to the upper side.

According to the above-described embodiment, first, the operation of the blocking plate 20 is performed through gear engagement with the air cylinder 41. Therefore, when the drone 1 is submerged in a rainy season or the like, the operation of the unmanned circuit breaker 1 is stopped and the problem of not being able to leave the vehicle is eliminated.

In addition, since the operation of the blocking plate 20 is performed through the combination of the worm wheel 44a and the worm gear 22, the blocking plate 20 is not released by an external force.

In addition, since the worm wheel 44b can be rotated by an external force through the communication groove 20a provided on the upper side of the blocking plate 20, the worm wheel 44b can easily cope with a failure in the unmanned circuit breaker 1. .

The embodiment according to the present invention has been described above. However, the above embodiment shows one preferred configuration of the present invention, which is not intended to limit the scope of the present invention. The present invention can be carried out in various modifications without departing from the spirit of the invention.

As described above, according to the present invention, it is possible to realize an unmanned circuit breaker of a parking system which is free from flood damage, does not overload the main power source of the unmanned circuit breaker, and can cope easily in the event of a failure.
