Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation and operation device for a rail transporter which is installed in a mountainous area or the like where it is difficult to level and transports heavy objects.

[0002]

2. Description of the Related Art Conventionally, this type of rail transporter has a forward / reverse switching lever for setting the traveling direction to forward or backward using an engine as a driving power source, and an accelerator lever for controlling the engine output. It has been known. The forward / reverse switching lever is provided in, for example, a transmission and reverses the direction of rotation of an output shaft of the transmission. The accelerator lever is connected to the throttle lever of the engine via a link wire, and the operation of the accelerator lever drives the throttle lever to control the engine output.

[0003]

The forward / reverse switching lever is arranged to operate in the left-right direction with respect to the traveling direction, for example, regardless of the traveling direction of the rail carriage. Is set, which makes it easy to make a mistake in the operation in the traveling direction. In addition, operators of this type of rail transport vehicle include employees who work on a temporary basis, and may not be familiar with the operation method of such a rail transport vehicle. From these two factors, the operator often mistakes the operation direction of the forward / reverse switching lever and moves the rail carrier in a direction opposite to the desired direction.
In particular, when such an operation error is made at the end point of the traveling rail, the transporter may be caused to travel to the end point side and derail.

In order to reduce such operation mistakes,
It is also conceivable to arrange the forward / reverse switching lever simply with its operating direction coincident with the traveling direction. However, even in this case, since the forward / reverse switching lever and the accelerator lever are separate bodies, there still remains a problem that the forward / backward switching lever and the accelerator lever are operated by mistake.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems at once, the present invention provides an operating lever which can be operated in the front-rear direction so that a rail carrier can travel in the operating direction. And a driving device for a rail transport vehicle in which the functions of an accelerator lever and a forward / reverse switching lever are sequentially performed only by the operation of the operation lever, thereby simplifying the driving operation of the rail transport vehicle. , In order to reduce the possibility of an operation error.

(The upper roller 12 is not shown.) The drive wheel 5 is connected to the output shaft of the transmission 6 as shown in FIGS. 1 and 2, and a cylindrical body 51 corresponding to a pinion tooth is provided around the outer periphery thereof. It was done. In this embodiment, the drive wheels 5 are arranged in two rows in the traveling direction. Thus, the main rail 101 is sandwiched from above and below by the driving wheel 5 and a driven wheel that is in contact with the upper surface of the main rail 101 (not shown), and the driving wheel 5 is meshed with the rack teeth 103 of the main rail 101 to transport the rail. The car 1 is running on the running rail 100.

Returning to the main theme, the driving operation device 2 has an operation lever 4 pivotally attached to an apparatus main body 21 so as to be tiltable in the front-rear direction, as schematically shown in FIGS. , A forward / reverse switching mechanism 80, a throttle lever drive mechanism 90, a clutch drive mechanism 70 shown in FIG. 2, and an operation lever forced return mechanism 10 shown in FIGS.

As shown in FIGS. 1 and 2, the apparatus main body 21 is disposed above a support plate 17 erected on the side of the driver's seat 13. When the operation lever 4 is located within the front-rear switching area A as shown in FIG.
It has a function of switching the rail transport vehicle 1 to run in the operation direction of the operation lever 4. More specifically, as shown in FIG.
1, a rotating piece 83 having a concave portion 84 into which the projecting portion 82 is fitted, and pivotally attached at a pivot point 83Y of the apparatus body 21, and a rotating end 85 of the rotating piece 83. A link wire 86 connected to the operation end of the forward / reverse switching lever 8 and transmitting the movement of the rotating end 85 to the forward / backward switching lever 8 is provided. Then, the protrusion 82
And the concave portion 84 are geared with each other,
The turning piece 83 is turned in accordance with the tilt of the operation lever 4. Further, when the operation lever 4 exceeds the front-rear switching area A, the engagement between the protrusion 82 and the recess 84 is set to be released.

When the operation lever 4 is operated in the forward travel control area Bf and the reverse travel control area Bb shown in FIG. 3, the throttle lever drive mechanism 90 changes the throttle lever 9 to the operation amount of the operation lever 4. And has a function of controlling the output of the engine 3. Specifically, for example, as shown in FIG. 3, a U-shaped groove 91 cut out at the base end portion 41 of the operation lever 4 is provided.
A long hole 92 drilled in a guide member 95 fixed to the apparatus main body 21, a pin 93 fitted into the groove 91 and the long hole 92 at the same time, and this pin 93 is connected to the operating end of the throttle lever 9. , A link wire 94 for transmitting the movement of the pin 93 to the throttle lever 9. The elongated hole 92 is provided in the radial direction with respect to the tilt center 4Y of the operation lever 4. When the operation lever 4 is located at the neutral position shown by a solid line in FIG.
It is set so as to be line-symmetric with respect to the long hole 92. Further, the groove shape of the intermediate portion of the groove 91 is made concentric around the tilt center 4Y, and the operation lever 4
4 or 6, that is, at the time when it is located at the boundary between the forward / reverse switching area A and the travel control areas Bf and Bb, the bent portion of the U-shaped groove 91 is set to overlap the elongated hole 92. ing. Therefore, in the forward / reverse switching area A, the pin 93 is fitted in the middle of the groove 91 and does not move due to the tilt of the operation lever 4. Thus, in the travel control areas Bf and Bb, the pin 93 is
At one end. Accordingly, with the tilting of the operation lever 4, the pin 93 is urged by one end of the U-shaped groove 91 to advance and retreat in the direction of the tilting center 4 </ b> Y along the long hole 92, thereby driving the throttle lever 9.

As shown in FIG. 2, for example, the clutch drive mechanism 70 transmits the expansion / contraction operation of the electric cylinder 76 to the tension pulley 74 via a spring 753, and causes the clutch 7 to perform a connection / disconnection operation. is there. Specifically, for example, the first arm 751 and the second arm 7
52, a spring 753, an electric cylinder 76, and a clutch operation switch (not shown). The first arm 751 has its base end pivotally supported at a pivot point 75Y provided on the housing of the rail carrier 1 and has its pivot end pivotally attached to the tip of the electric cylinder 76. is there. The second arm 752 has a base end pivotally supported at a pivot point 75Y so as to be rotatable independently of the first arm 751. A tension pulley 74 is pivotally mounted on the rotation end. .
In the electric cylinder 76, when the operation lever 4 is in the forward / reverse switching area A
When the operation lever 4 is located in the forward / reverse switching area A, the clutch operation switch is switched on / off when the operation lever 4 is located in the forward / reverse switching area A. Shrinkage, travel control area B
When it is located at f and Bb, it is set to extend. The spring 753 connects the first arm 751 and the second arm 752 to the respective rotating ends.
The spring force is, for example, the first arm 75 shown in FIG.
The tension can be adjusted by a tension adjusting mechanism 754 using screw feed provided on one side. Therefore, the expansion / contraction operation of the electric cylinder 76 is converted into a rotation operation of the first arm 751 and transmitted to the second arm 752 via the spring 753, so that the tension pulley 74
Will move forward and backward. With such a clutch driving mechanism 70, the operation lever 4 is moved in the forward / reverse switching area A.
, The clutch 7 is disconnected and the operation lever 4
Is located in the travel control areas Bf and Bb, the clutch 7 is connected. Further, as described above, by making the clutch driving mechanism 70 a mechanism for transmitting the expansion and contraction operation of the electric cylinder 76 to the tension pulley 74 via the spring 753, when an abnormal load is applied to the engine 3, for example, The belt 73 is prevented from being cut, and the tension thereof can be adjusted by the tension adjusting mechanism 754 even when the belt 73 becomes loose due to aging.

The operation lever forcible return mechanism 10 has a function of forcibly returning the operation lever 4 to the front / rear switching area A upon detection of an external signal, and thereafter returning the operation lever 4 to a state where it can be operated externally again. It is. In this embodiment, as shown in FIGS. 8 and 9, a pair of rollers 14, a roller support member 15 for supporting the rollers 14, and an electric cylinder 16 disposed on a support plate 17 below the operation lever 4.
And a return mechanism operation switch (not shown) for operating the cylinder 16. The cylinder 16 supports the roller 14 and the roller support member 15 at the distal end thereof and moves up and down. Then, as shown in FIG. 8, when the cylinder 16 is in the most contracted state, the pair of rollers 14 is positioned below the operation lever 4 so that the external operation by the operator of the operation lever 4 is not restricted. . In addition, as shown in FIG. 9, the pair of rollers is raised so as to sandwich the arm of the operation lever 4 according to the extension of the cylinder 16, and one of the rollers 14 is brought into rolling contact with the arm 42 of the operation lever 4. When the cylinder 16 is in the most extended state, the operation lever 4 is set up so as to be forcibly returned to the front / rear switching area A. The cylinder 16 automatically performs a series of movements from the most contracted state to the most extended state once the return mechanism operation switch is turned on, and then to the most contracted state again. By adopting such a cylinder 16, the operation lever 4
Is forcibly returned to the front / rear switching area A, and then the operation lever 4 is returned to a state where it can be externally operated again.

Also, in this embodiment, FIGS.
As schematically shown in FIG. 3, a brake driving switch 77 that is turned on / off according to the position of the throttle lever 9 is provided. For example, when the throttle lever 9 starts moving from an idling position, the driving switch 77 is turned on. The brake is set to switch off from, and the brake is released.

The operation of the embodiment constructed as described above will be described. The operation lever 4 is located exactly in the middle of the operation area,
That is, in a state where the throttle lever 9 is at the neutral position shown by the solid line in FIG. 3, the throttle lever 9 is located at the idling position and the forward / reverse switching lever 8 is located at the intermediate position. As a matter of course, the electric cylinder 76 is not driven, and the first arm 751, the second arm 752, and the tension pulley 74 are in a state shown by a chain line shown in FIG. In addition, the brake is also in a state where the rail transport vehicle 1 is being braked.

From this state, for example, the operator moves the rail transport vehicle 1
When the operation lever 4 is tilted in the forward direction in order to advance the forward movement, the forward / reverse switching mechanism 80 is first activated. That is,
The rotating piece 83 is rotated by the gear engagement between the protruding portion 82 and the concave portion 84, and the forward / reverse switching lever 8 is operated to the forward side via the link wire 86. Then, in the state shown in FIG. 4, that is, when the operating lever 4 reaches the boundary between the forward / reverse switching area A and the forward traveling control area Bf, the transmission 6 is reliably switched to the forward side, and the clutch operation switch is switched. The electric cylinder 76 starts to extend. At this time, the engagement between the projection 82 and the recess 84 is released, and the forward / reverse switching mechanism 80 does not operate even if the operation lever 4 is further tilted.

On the other hand, the throttle lever driving mechanism 90 does not operate in the front / rear switching area A. That is, in the front-rear switching area A, since the pin 93 is fitted in the middle portion of the U-shaped groove 91, it does not move and the throttle lever 9 does not move. When the operating lever 4 is further tilted from the state shown in FIG. It starts to move in the direction of the tilt center 4Y along the hole 92. Then, with the movement of the pin 93, the throttle lever 9 is driven to increase the output of the engine 3, and at this time, the brake is released. When the electric cylinder 76 extends to a predetermined position, the first
The arm 751, the second arm 752, and the tension pulley 74 are in the solid line state shown in FIG. 2, and the clutch 7 is in the connected state. As a result, the rotation of the engine 3 is transmitted to the drive wheels 5, and the rail carrier 1 starts to move forward. Actually, at this time, since there is a time delay for the extension of the electric cylinder 76, the clutch 7 is engaged after the engine 3 is slightly blown up, and the rail carrier 1 starts running. Thereafter, when the operating lever 4 is further tilted, the throttle lever 9 is driven according to the angle, and the output of the engine 3, that is, the vehicle speed increases. Eventually operating lever 4
The engine output becomes maximum at the position shown in FIG.

When the operation lever 4 is returned from the state shown in FIG. 5 to the state shown in FIG. 3, the operation of the rail carrier 1 is completely reversed.
Stops. In addition, if the operation lever 4 is tilted from the state shown in FIG. 3 to the reverse side, the forward / reverse switching lever 8 moves in the opposite direction to the above, and the rail carrier 1 moves backward. The description of is omitted.

The operation of the operation lever forced return mechanism 10 will be described with reference to the present embodiment, for example, as this return mechanism 10 is applied as follows.
That is, a limit switch having an arm is employed as the return mechanism operation switch, and the arm for turning on the limit switch is extended downward from the lower surface of the rail carrier. On the other hand, the traveling rail 100 near the traveling end point of the rail transport vehicle 1 is provided with a protruding portion that comes into contact with the arm as the rail transport vehicle passes. In this way, when the rail transport vehicle 1 travels in the direction of the end point, the arm is brought into contact with the projecting portion and moved to turn on the return mechanism operation switch. Note that, for example, an electric circuit is set so that the return mechanism operation switch is turned on only when the rail transport vehicle 1 travels toward the end point. As a result, the operation lever compulsory return mechanism 10 operates near the travel end point, and the rail transport vehicle 1 traveling toward the travel end point automatically stops at the travel end point. Therefore, it can be suitably used for unmanned traveling.

As described above, according to the present embodiment, the following effects can be obtained. That is, since the operation lever 4 is disposed so as to be operable in the front-rear direction so that the rail transport vehicle 1 can travel in the operation direction, the operation of moving the rail transport vehicle 1 in a direction different from the traveling direction is performed. The possibility of mistakes can be reduced. Further, since the functions of the conventional accelerator lever and forward / reverse switching lever are sequentially performed only by operating the operation lever 4, there is no need to mistakenly operate the forward / backward switching lever and the accelerator lever. In addition, the driving operation of the rail carriage 1 becomes very simple. Particularly, as an effect peculiar to the present embodiment, the clutch 7 is connected after the engine 3 is slightly blown up at the start of traveling of the rail carrier 1, so that the possibility of engine stall at the time of starting can be reduced.

The brake is applied to the engine 3 and the driving wheels 5.
Since the brake is forcibly actuated in a state where the brakes are disconnected from each other, the brake can be reliably actuated in a stopped state. Further, the rail transport vehicle 1 traveling toward the travel end point is automatically stopped at the travel end point by using the operation lever compulsory return mechanism 10, so that the rail transport vehicle 1 is stopped due to a brake operation error or the like. However, it is possible to reduce the possibility of the vehicle going past the end point and derailing, etc., thereby improving safety. At the same time, the operation lever forcible return mechanism 10 forcibly moves the operation lever 4 into the front / rear switching area A, then releases its operation and returns the operation lever 4 to a state in which the operation lever 4 can be externally operated again. ,
No special operation is required to release the operation of the mechanism 10, and the operation of the operation lever 4 is facilitated again.

The present invention is not limited only to the above-described embodiment. For example, the forward / reverse switching mechanism and the throttle lever driving mechanism are not limited to the mechanism as in the embodiment, but can be variously modified as long as they have similar functions. For example, these are not limited to mechanical ones. The forward / reverse switching lever and the throttle lever are driven by a motor or the like, while the forward / backward switching lever is used when the operation lever is located in the forward / backward switching area. Signal to drive the motor for the vehicle, and when the operation lever is located in the travel control area,
An electrically configured device such as a device that outputs a signal for driving a motor for a throttle lever may be used. In the above-described embodiment, the clutch uses a tension clutch system for driving the electric cylinder, but may use another linear actuator such as a hydraulic cylinder instead of the electric cylinder. Further, the clutch is not limited to the tension clutch type. The operation lever forced return mechanism is not limited to the one in the embodiment, and its application is to expand the operation method of the rail carrier, for example, forcibly stop at an arbitrary position by a radio signal, and to improve safety. Various modifications are possible.

Furthermore, the present invention has the same effect even if the rail power carrier has, for example, an electric motor as its running power source. In this case, the forward / reverse switching is performed by an electric switch that reverses the electric motor according to the position of the operation lever, or the motor output is increased or decreased according to the position of the operation lever. What is necessary is just to apply the mechanism performed by controlling.

In addition, the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0030]

According to the driving operation device for a rail car according to the present invention, the following effects can be obtained as described in detail above. In other words, since the operation lever is arranged to be operable in the front-rear direction so that the rail transport vehicle can travel in the operation direction, there is a possibility of an operation error that the rail transport vehicle travels in a direction different from the traveling direction. Can be reduced. Further, since the functions of the conventional accelerator lever and the forward / reverse switching lever are sequentially performed only by operating the operation lever, the forward / backward switching lever and the accelerator lever are not operated by mistake. The driving operation of the rail car becomes very simple. At the same time, a safety device or the like that has conventionally been required in response to such an operation error is not required.

If a brake is provided on the rail transporter and the brake is forcibly operated in a state where the driving power source and the drive wheels are separated, the brake can be reliably operated in the stopped state. Can be activated. Further, if the rail transporter detects an external signal, the rail transporter is provided with an operation lever forced return mechanism for forcibly moving the operation lever into the front / rear switching area, and thereafter returning the operation lever to a state where it can be externally operated. If this is the case, the running of the rail carrier can be automatically stopped using an external signal, which contributes to an improvement in safety. Further, after the operation of the mechanism, a release operation for re-operating the operation lever is not required, so that there is no difficulty in handling.
