Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for remotely controlling the combustion engine of a vehicle in an idling state to drive a hydraulic motor using a gondola or the like installed on a column that expands and contracts with a hydraulic cylinder mounted on the vehicle. The present invention relates to a remote start/stop operating device for a combustion engine that operates a hydraulic motor that can be stopped automatically and remotely started only when a change lever is in a neutral position.

High-altitude work vehicles and bridge repair vehicles that have a gondola for workers to ride on at the tip of the support and move it to the desired position, as well as cranes such as Xif that move suspended objects as appropriate.
In vehicles where the props, cranes, etc. are extended and tilted using several hydraulic cylinders, the engine mounted on the vehicle is kept in an idling state at all times so that the gondola etc. can be arbitrarily displaced during the work. It is configured to be able to drive a hydraulic motor with this power.

By the way, for example, a worker at the rear of the aerial work vehicle 1 shown in FIG. When working inside the gondola 2 etc. for a long time while holding the hydraulic cylinders 4 and 5 in place, i.e. the hydraulic cylinders 4 and 5 are no longer
When there is no need to operate the hydraulic motor, the hydraulic circuit is locked so that no trouble will occur even if the idling engine is stopped in order to operate the hydraulic motor (not shown).

The operator inside the gondola can stop the engine by turning off the main switch, but if a worker inside the gondola wants to reactivate the hydraulic cylinder and change its position, he must notify the operator. In addition, if the driver is not present, the engine cannot be restarted.

Therefore, even while the gondola is stationary at a predetermined position and the gondola is being worked on, the engine is generally kept in an idling state at all times.

Therefore, even if the work at a given position is prolonged,
The drawback is that fuel and electricity are wasted as a result of the engine being in operation and each electrical system being activated. Furthermore, there is a risk that the driver may accidentally operate the main switch and start the vehicle even though he or she is working inside the gondola.

When attempting to remotely stop and start a combustion engine to avoid such drawbacks, the following situation occurs.

In other words, while the engine is stopped and a worker in the gondola is working, another worker in the driver's seat accidentally touches the change lever, causing the change lever, which should be in the neutral position, to move to the starting position. There is.

In this case, if a worker inside the gondola remotely starts the engine in an attempt to activate the hydraulic motor without noticing this, the starter motor will cause the vehicle to start, resulting in an extremely dangerous situation.

The present invention was made in order to solve the above-mentioned problems, and when there is no need to operate the hydraulic cylinder, the operator can remotely stop the operation of the engine and save fuel and electricity during work. A remote start/stop control device for vehicle combustion engines that saves energy by avoiding energy consumption, and allows the engine to be restarted remotely only when the change lever is in the neutral position when operating the hydraulic cylinder. We are committed to providing the following.

Its features include an ignition circuit and a star circuit connected to the main switch, a remote ignition switch that can be operated outside the driver's seat, a starter switch, an ignition relay that is energized by the remote ignition switch, and an ignition relay that is energized by the remote ignition switch. It incorporates an ignition opening/closing contact that moves, a safety switch that opens and closes depending on the position of the change lever, a safety relay that is energized by this safety switch, and a safety opening/closing contact that is activated by this relay, and is in an idling state because the hydraulic motor IK operates. This makes it possible to remotely stop and safely start a combustion engine.

Hereinafter, the present invention will be explained in detail based on examples thereof.

FIG. 2 is a circuit diagram of an embodiment applied to a gasoline engine, in which a remote start/stop operation device is incorporated into a circuit connected to a main switch.

The changeover type main switch 11 connected to the batch IJIO and mounted on the driver's seat has an ACC contact, an IG contact, a self-returning STI contact, and an ST2 contact, and the ACC contact has accessories for radio No. 12, etc. - A circuit 13 is connected, and the IG contact is connected to an electrical system circuit 15 that supplies power to various meters, lamps, etc. 14, and supplies low voltage current to the primary coil of the ignition coil/I/17 via a resistor 16. Then, from the secondary carp μ, the distributor 18
Ignition coil circuit 19 that induces high voltage current in
An ignition circuit 20 is connected in which the ignition circuit 20 and the ignition circuit 20 are installed in parallel. In addition, ignition car) v17 has ST
A connecting wire 21 is attached that directly connects the two contacts.

A starter circuit 24 that operates a starter magnet 22 for supplying power to a starter motor 23 is connected to the ST1 contact.

As described above, in the start/stop circuit in the driver's seat, the ignition circuit 20 is connected to the electrical system circuit 15 and the Ibnira river link 4.
An ignition opening/closing contact 31 is interposed between the point 25 branching to the + path 19 and the IG contact, and a connection line between the ignition opening/closing contact 31 and the L contact is connected to the gondola or a portable remote control box 32. A remote ignition circuit 34 is connected via an attached remote ignition switch 33.

This remote ignition circuit 34 includes a remote control box 32 in parallel with the remote ignition switch 33.
Inside pilot lamp 35, safety lamp opening/closing contact 3
6, a safety lamp 37, an indicator lamp 38 in the driver's seat, and an ignition relay 39 are interposed. In addition, this ignition relay 39 makes the ignition opening/closing contact 31 of the ignition circuit 20 "on" in the energized state.

Further, a two-contact self-resetting starter switch 40 in the remote control box 32 is interposed between the remote ignition switch 33 and the ignition relay 39 of the remote ignition circuit 34, and is connected to the ignition coil circuit 19 and the starter circuit 24. A starter connection line 43 is provided which has an ignition connection line 41 and a safety switching contact 42 that are connected to each other independently.

It should be noted that if the ignition connection line 41 is not required, the starter switch 40 does not need to be a two-contact type.

In addition to the above-mentioned circuit, a safety circuit 45 is provided as a branch of the electrical system circuit 5, and this safety circuit 45 includes a safety switch 46 that closes when a change lever (not shown) located in the driver's seat is inserted into the insertion position. A safety relay 47, which is energized via the safety switch 46, is interposed in series. When the safety relay 47 is energized, the safety lamp opening/closing contact 36 and the safety opening/closing contact 42 are simultaneously brought into a "conducting" state.

The safety switch 46, which operates depending on the insertion position of the change lever, is in the "on" position when the change lever is in the neutral position, and in the "off" position when the change lever is in the forward/reverse starting position other than the neutral position. Although not shown, it is operated by known means.

When a changeover type ignition switch 48 is interposed in the remote ignition circuit 34 and installed at the driver's seat or other locations, the remote ignition switch 33 must also be a changeover type as shown in FIG. In addition,
This changeover type ignition switch 48 does not necessarily have to be provided, but it is convenient if it is provided, since the engine can be stopped from outside the gondola, for example, from the driver's seat.

According to the configuration described above, the gasoline engine can be started and stopped as follows.

First, we will explain the operations in the driver's seat. When the driver turns the main switch 11 into the IG contact, the indicator lamp 38 lights up and at the same time the electric circuit 15 is energized. If the indicator lamp 38 does not light up, it means that the ignition opening/closing contact 31 is "off", and the changeover type ignition switch 48 is turned to the other side. That is, since the remote ignition switch 33 in the remote control box 32 is placed in one of its AI1 contacts and B1 contacts, the changeover type ignition switch 48 is placed in the corresponding contact, which is the A2 contact in FIG. As a result, power from the battery 10 is supplied to the IG contact, the A2 contact of the changeover type ignition switch 480, the A1 contact of the remote ignition switch 33, and the ignition relay 39. When the ignition opening/closing contact 31 is in the "open" state, the indicator lamp At the same time as the 3rd light is turned on, the νE thread system circuit 15 is energized.

In this state, when the driver turns on the main switch 11 to the ST1 contact, the ST2 contact is also turned on at the same time, so the starter motor 23 is driven and at the same time high power is supplied to the ignition coil/l/17, causing the engine starts. After confirming startup, let go of main switch 11,
Although it self-returns to the IG contact, low power is supplied to the ignition coil circuit 19 via the ash removal resistor 16, so
The engine continues to idle.

Of course, the engine can be stopped by returning the main switch 11 to at least the ACC contact.

Next, the operation of the remote control box 32 inside the gondola will be described.

Now, assuming that the engine is in idling operation, the hydraulic pump is driven by the power, and the operator inside the gondola 2 can operate the hydraulic cylinders 4 and 5 using the remote control lever 3a as appropriate.
, and move the poom 6 to the desired position.

At this time, the remote ignition circuit 34 is energized as described above, so the pilot lamp 35 and the indicator lamp 38 are lit. Also, since the change lever is naturally in the neutral position, the safety switch 46 of the safety circuit 45 is set to ``one connection'', the safety relay 47 is activated, the safety lamp opening/closing contact 36 is ``open'', and the safety lamp 37 is also lit. are doing.

Next, when the gondola reaches the desired position, the hydraulic cylinder 4,
5 is stopped and the hydraulic circuit is locked. Therefore, in order to stop the engine that was driving the hydraulic pump, the operator switches the remote ignition switch 33 of the remote control box 32 to the B1 contact. As a result, the power to the pilot lamp 35, safety lamp 37, indicator lamp 38 and ignition relay 39 is cut off, the ignition opening/closing contact 31 of the ignition circuit 20 becomes "off", and the ignition coil Iv17
When the power supply to the engine stops and the engine stops, the electric system circuit 15 is also cut off.

When a certain work is completed and the pool 6 is to be moved or displaced, the worker turns the remote ignition switch 33 to B1.
Switch from contact to A1 contact.

Since the main switch 11 on the driver's seat remains in the IQ contact, the pilot lamp 35 and indicator lamp 38 light up, and the relay 39 operates, and if the change lever is in the neutral position, the safety lamp 37 also lights up at the same time. The ignition opening/closing contact 31 of the ignition circuit 20 also becomes "open".

The worker uses the pilot lamp 35 and safety lamp 3.
After confirming that both of
The ignition coil 17 and the starter magnet 22 are energized through the starter connection wire 43 of the safety opening/closing contact 42 which is in the "on" state and the "on" state, respectively, and the engine is started. When the starter switch 40 is released, the ignition connection line 41 that supplies high power is cut off together with the starter connection line 43, but a low power is applied to the ignition coil through the ignition opening/closing contact 31 and the resistor 16, which are in the "on" state. /I/17, and the engine becomes idling. Therefore, the hydraulic pump can be driven to displace the poom 6 again using the hydraulic cylinders 4 and 5.

By the way, if the shift lever is in the starting position for some reason while the engine is stopped, the safety switch 46 will be turned off9, the safety relay 47 will not operate, and the safety opening/closing contact 42 and The safety lamp opening/closing contact 36 is also "off".

Therefore, when the operator knows that the safety lamp 37 is not lit, he knows that the engine cannot be started.

Further, even if the starter switch 40 is pressed without realizing that the safety lamp 37 is not lit, the engine will not be started because the safety opening/closing contact 42 is in the "off" state.

In addition, there are cases where it is not necessary to supply high power to the ignition coil/I/17 when starting.
The starter switch 40 only needs to be able to drive at least the starter motor 23. Therefore, the ignition connection line 41 described above may be omitted.

As described above, the operator can independently start and stop the engine safely without any communication with the driver.

In the above operation, the operator only needs to operate the starter switch 4o after confirming that the pilot lamp 35 and the safety lamp 37 are lit, so Eve = 7:
? [L path 20 conduction state and change lever position;
The type can be easily confirmed, and the driver can also confirm continuity of the ignition circuit 20 through the indicator lamp 38 on the driver's seat.

Furthermore, even when the operator has stopped the engine, if the operator turns the selector type ignition switch 48 to the other side, the ignition relay 39'! Therefore, if the ignition opening/closing contact 31 is in the "open" state, the driver can operate the switch 11 to start the engine.

FIG. 3 shows an embodiment applied to a diesel engine, and parts that are the same as those described above are given the same reference numerals and explanations will be omitted.

A glow circuit 52 that supplies power to the glow plug 51 is connected to the G contact of the main switch 11, and in addition, a fuel control relay assembly 7153 is connected to the ignition circuit 20 and starter circuit 24 via the ignition opening/closing contact 31. O, 1: bi) 2-2μ
Connection lines 55, 56 leading to the control motor 54 are connected.

The remote control box 32 has a starter connection line 4 connected to the remote ignition circuit 34 with the above-mentioned self-resetting starter switch 40 and safety switching contact 42 interposed therebetween.
3, a glow connection line 58 with a glow switch 57 is provided in parallel, which glow connection line 58 is connected to the glow circuit 52.

According to the above configuration, when the remote ignition switch 33 in the remote control box 32 is switched, the ignition relay 39
When the energization is cut off and the ignition switching contact 31 is disconnected, the FUE P controller μ relay assembly 53 stops operating, and the diesel engine in the idling state stops.

If you do not want to drive the hydraulic motor after working in this state, switch the remote ignition switch 33, energize the ignition relay 39, and close the ignition open/close contact 3.
Make 1. ``Tsu''. The main switch 11 on the driver's seat is IG.
Since it is in contact, the electrical system circuit 15 is energized.

Next, the operator turns on the glow switch 57 to energize the glow circuit 52 and heat the glow plug 51. If the change lever is in the neutral position, the safety opening/closing contact 42 is open, so if the starter switch 40 is then pressed and the starter motor 23 is driven once, the engine can be started.

When the change lever is in the start position, the safety opening/closing contact 42 is set to "1", so even if the operator presses the starter switch 40, the engine will not start.

As described above in detail regarding the gasoline engine and diesel/l/engine, the present invention incorporates a switch and a relay that can be remotely operated outside the driver's seat in the ignition circuit and starter circuit of the combustion/engine start/stop operation device. The engine can then be remotely stopped and started in idle link condition to drive the hydraulic motor.

As a result, it is possible to stop the engine during work at a certain position, avoiding wasteful consumption of fuel and electricity, and also avoiding the risk of the driver accidentally starting the vehicle during work. can do.

Furthermore, if the change lever is not in the neutral position, remote activation cannot be performed, so if the operator operates the starter switch, the vehicle will start using the starter motor, which is an extremely dangerous situation! You can also avoid the back.
