Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a monorail golf cart used at a golf course.

(Naka) Prior Art Recently, there has been a trend toward mechanization of golf equipment transportation work at golf courses due to problems such as labor shortages and rising labor costs.

Specifically, there are handcart-type golf carts and electric vehicle-type golf carts, but due to problems such as maneuverability and damage to the grass, monorail-type golf carts have emerged and are being put into practical use.
However, although existing monorail golf carts have solved the problems of maneuverability and turf, it is not possible to install the monorail in the center of the golf course, so depending on the flight of the ball, the golf cart and the player or kayak may be separated. In some cases, the distance between carts can be long, and further improvement was desired in terms of cart operability. ←→ Purpose of the Invention The present invention has been invented in view of the above points, and even when the distance between the golf cart and the player or the player or the player is large, the operation control device using remote control means can be controlled by other operation control devices. An object of the present invention is to provide a monorail type golf cart that starts and stops the golf cart by remote control and prevents injuries to golf players and players.

a first motion control device that controls the movement of the cart by manual operation; a second motion control device that controls the movement of the cart by a control means disposed at a predetermined location on the monorail; and a remote control means. A third controller that controls the operation of the cart by
and a fourth motion control device that detects the presence of an obstacle in front of the cart and controls the motion of the cart, and the starting motion of the cart is controlled by the first motion control device.
The self-holding function of the first or third operation control device is performed by closing one of the switches provided in the operation control device and the third operation control device and connected in parallel to each other, and The stopping operation is the above-mentioned first, second, third
, the holding function is released by opening any one of the switches provided in each of the fourth operation control devices and connected in series with each other.

7 is an electromagnetic solenoid that applies a mechanical brake to the cart 2, 38 is a capacity for delaying the operation time of this electromagnetic solenoid 37, and 39, 39 are brake resistors for operating the drive motors 17, 17 as electric brakes. It is.

The above components are connected as follows.

That is, one drive motor 17 has a pair of relay contacts 27,
27', the other drive motor 17 is connected to the battery 20 via another pair of relay contacts 29, 29/, respectively, and when each of these relay contacts is switched and connected to the terminal a, the power is supplied. It is becoming more and more common. Further, when the relay contacts 27' and 29' are respectively switched and connected to the terminal b, each drive motor 17 is connected to the brake resistor 39 through the main switch 21, thereby producing dynamic braking. Relay coils 28 and 30 for switching relay contacts 27, 27 or 29, 29' are connected in parallel, and one end thereof is connected to the positive pole of battery 20 via a parallel circuit of start switch 22 and starting relay contact 33, and stop switch 23. The other end is connected to a parallel circuit of the station switch 24 and non-stop switch 25, and the emergency stop switch 2.
6. Connected to the negative electrode of the battery 20 via the stop relay contact 35 and the main switch 21.

Therefore, the relay coils 28 and 30 are de-energized when the stop switch 23, the station switch 24 when the non-stop switch 25 is opened, the emergency stop switch 26, and the stop relay contact 35 are opened, and the drive motor is turned off. 17, 17 will be subjected to dynamic braking. A radio receiver 14 having a starting relay coil 34 that closes a starting relay contact 33 and a stopping relay coil 36 that closes a stopping relay contact 35 is connected in parallel with a series circuit of an electromagnetic solenoid 37 and a relay contact 31. , and is also connected to the battery 20 via the main switch 21.

The relay coil 32 that opens the relay contact 31 is connected in parallel with a capacitor 38 that delays the operation time of the electromagnetic solenoid 37, and one end of the relay coil 32 is connected in parallel with a capacitor 38 that delays the operation time of the electromagnetic solenoid 37. and is connected to the positive electrode of the battery 20, and the other end is connected to the negative electrode of the battery 20 via the main switch 21.

Further, a branch BC including a backflow blocking diode D2 is provided between both ends of the starting relay contact 33 and the start switch 22 via the terminals b of the relay contacts 29 and 29'.

Therefore, each relay coil 28, 30, 32 is supplied with power by closing the starting relay contact 33 or the start switch 22, but since this power supply causes the relay contact 29 to be closed by excitation of the relay coil 30, once the relay coil 30 is closed, the relay coil 30 is excited. After the starting relay contact 33 or the start switch 22 is closed, power is supplied via the branch line BC and the motor is self-maintained. This self-holding function is achieved by starting relay contact 33.
Or, it occurs when the relay contact 29 is closed due to the excitation of the relay coil 30 based on the closing of the start switch 22.
By manually operating the operating lever 6, the brake resistors 39, 39, etc. constitute a third type of motion control device.

The emergency stop switch 26 opens when the stopper 8 detects an obstacle, and since this switch is inserted into the power supply path of the relay coils 28 and 30,
By opening this switch, the self-holding function of the relay coils 28 and 30 is released, and the aforementioned stop switch 23 is released.
The cart 2 is stopped in the same manner as when the station switch 24 is opened when the non-stop switch 25 is opened, or when the stop relay contact 35 is opened.

Therefore, emergency stop switch 26, stopper 8, relay coils 28, 30, relay contacts 27, 27', 29, 29'
, drive motors 17, 17, brake resistors 39, 39, electromagnetic solenoid 37, etc. constitute a fourth type of operation control device. As is clear from the configurations of the first to fourth operation control devices described above, the stop switch 2 of the first operation control device
3. Station switch 24 of the second operation control device;
The stop relay contact 35 of the third operation control device and the emergency stop switch 24 of the fourth operation control device are connected to the relay coil 2
Since the start switch 2 in the first operation control device is inserted in series with the power supply circuits 8 and 30, when either switch or relay contact is open, the start switch 2 in the first operation control device
Even if the start relay switch 33 in the second or third motion control device is closed, the cart 2 will not start.

Then, when the main switch 21 is turned on and the start switch 22 is turned ON by operating the operating lever 6, or when the transmitting relay contact 33 is turned ON by the function of the wireless receiver 14, the relay contacts 27, 27', 29 and 29' are connected to the terminal a, respectively, and power is supplied to the drive motors 17 and 17, so that the cart 2 starts running.

In this state, either the stop switch 23, the station switch 24 when the non-stop switch 25 is opened, or the emergency stop switch 26 is turned OFF, or the stop relay contact 35 is turned OFF by the action of the wireless receiver 14.
Then, the power to the relay coils 28 and 30 is cut off, and the relay contacts 27' and 29' are connected to terminal b, so that the motor 1
Brake resistors 39 and 39 are connected to the motors 17 and 17, and power generation TjI is applied to the motors 17 and 17. After a delay time due to the ζ capacity 38, the power supply to the relay coil 32 is stopped and power is supplied to the electromagnetic solenoid 37. is started and cart 2
A mechanical brake is applied to stop cart 2. Finally, the wireless transmitter 10 and receiver 14 will be explained.
