Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a crane operation desk.

[0002]

2. Description of the Related Art Conventionally, various cranes such as container cranes have been widely used. FIG. 3 is a diagram showing an entire configuration of a conventional container crane. FIG. 4 is a diagram showing a crane operation situation in the crane cab.

As shown in FIGS. 3 and 4, an operator operates a container crane 50 while checking a container 52 and the like below a driver's cabin 51 while operating controllers and various switches on operation consoles 53 and 54. It is performed by operating.

At this time, since the operator operates while checking the conditions of the crane and the container, depending on the type of operation, it is necessary to perform quick operation without looking at switches on the operation desks 53 and 54. On the other hand, in the crane operation process, for an operation having a sufficient time, a switch operation is performed while checking the operation desks 53 and 54.

[0005] As functions in crane operation, for example, there are the following functions in a container crane. FIG. 5 is a configuration diagram showing an example of a right operation desk of a conventional container crane. FIG. 6 is a configuration diagram showing an example of a conventional left operation desk of a container crane.

As shown in FIG. 5, a right operation desk 53 has a master controller 2 for speed command, an emergency stop push button 3, a twist lock operation switch 4, a spreader tilt switch 5, an alarm siren sound switch 6, and an operation switch. A location selection switch 7, a spreader original position return push button 8, a spreader horizontal return push button 9, a boom position indicator light 10, and a hatch cover cancel push button 11 are provided.

On the other hand, as shown in FIG. 6, the left operating desk 54 has a master controller 2, an alarm siren sounding switch 6, a flipper selection switch 22, an extreme short-circuit push button 23, a spreader length indicator 24, a flipper up / down switch. 25, a spreader length selection switch 26, a spreader oil pump start push button 27, a landing short-circuit push button 28, a failure indicator 29, a next display push button 30, a display changeover switch 31, a failure reset push button 32, and an alarm cutoff push button 33. I have.

The main functions will be briefly described. FIG.
FIG. 4 is a diagram showing a state in which a spreader is attached to a container. In a container crane, a hanging tool called a spreader 55 is attached to the container 52,
Lifting and hanging containers. First, the spreader 55 is positioned on the container 52 on the cargo ship, and the spreader 55 is lowered on the container 52 after adjusting the horizontal inclination and the like with the spreader tilt switch 5. At this time, the landing limit switch does not operate, but when it is necessary to continue cargo handling, the landing short-circuiting push button 28 is pressed. Then, the twist lock operation switch 4 is pressed to rotate and lock the hook 56 inserted into the hole 57. In this landing work, a flipper is used as a positioning guide. That is, the flipper up / down switch 25 is turned on to lower the flipper 58,
The spreader 55 is lowered to land.

Thereafter, the container 52 is lifted, traversed by the master controller 2, returned to a level with the spreader horizontal return push button 9, and then lowered to a predetermined position on the ground. During this time, the extreme short-circuit push button 23 is used as necessary to operate the crane beyond the normal limit position, the length of the spreader is adjusted with the same selection switch 25, the display changeover switch 31 and the next display push button 30 are used. To switch the display, or when a failure occurs, check the failure indicator 29 and operate the failure reset push button 32.

[0010]

As described above, a container crane and the like are provided with a large number of functions, and in some situations, an operator performs a delicate operation while confirming an operation target below. There is a need. For example, operations such as hoisting and traveling of a crane, traversing and operation using an extreme short-circuiting push button 23, landing confirmation operation, flipper raising / lowering operation, and the like. Such an operation is dangerous if not performed while checking the actual situation of the operation target side, not while looking at the operation desks 53 and 54, and the cargo handling of the container must be performed in a short time. Driving while looking at the operation desk not only takes time, lowers cargo handling efficiency, but also increases the payment of demurrage charges.

On the other hand, since operations such as selection of the length of the spreader, activation of the spreader oil pump, reset of the failure, switching of the display, etc. are not a series of operations during normal cargo handling, they can be performed while checking the operation desks 53, 54. It is enough.

For these reasons, the positions of switches and indicator lights on the operation desk generally have different requirements depending on the installation condition of the crane and the skill of the operator. Therefore, the type and quantity of switches and indicator lights on the operation desk differ from crane to crane and are designed each time. In addition, since the mechanical design of the container cranes is different each time, the necessity of operating supplies corresponding thereto is also a reason why the operating desk design differs for each crane.

However, if the operation desk design differs for each crane as described above, it is difficult to reduce the cost by standardization, and it takes time for the design, and the delivery time becomes longer.

On the other hand, in the cab 51, there is a remote I / O device 59 in addition to the operation desk. The installation of the device 59 requires a space, and the number of wires to the operation desk is large. For this reason, it has been conventionally required to save space, reduce external wiring, reduce cost, and facilitate wiring work.

The present invention has been made in consideration of the above circumstances and has a first object as a standardized crane capable of responding to various arrangement requirements without changing the structure of an operation desk or mounting articles. An operation console is provided. A second object of the present invention is to provide a crane operating desk that can save space in the cab and reduce external wiring in addition to the above objects.

[0016]

Means for Solving the Problems In order to solve the above problems, the invention corresponding to claim 1 has been made for a crane operating desk. First, the crane operating desk according to the present invention includes a first operating device group having a fixedly provided physical operating portion and a second operating device group provided on a touch panel so as to be able to change settings. Operating devices are provided. The signals of this group of operating devices are transmitted to a higher-level control device or the like via a remote I / O device.

Here, the first operating device group is provided with at least a master controller and an emergency stop push button. In other words, the first group of operating devices is selected based on the fact that the first group of operating devices is generally used in the type of crane.

As described above, the first operating device group has the fixedly provided physical operating portion, and the second operating device group is provided on the touch panel so that the setting can be changed. It is possible to provide a standardized crane operating desk that can respond to various arrangement requirements without changing the mounting equipment. Further, since the remote I / O device is also provided on the operation desk, it is possible to save space in the cab and reduce external wiring.

Next, according to a second aspect of the present invention, in the first aspect of the invention, the first group of operating devices includes only operating devices to be operated without watching the operating device itself. Can be

If the operating device has a fixedly provided physical operating portion, the crane operator can adjust the operation with a sense of a fingertip particularly in operability. In addition, in the case of such an operating device, if the position of the operating device is confirmed in advance, the crane operation can be performed while checking the crane operation target without almost seeing the operation desk.

On the other hand, an unsteady operation that allows the operator to observe the operation itself or an operation that has a time margin for the operation can be assigned to the touch panel as the second operation device group. The same effect as the invention according to claim 1 can be obtained while securing the function originally required of the desk. Further, since the number of the first operation device group can be reduced, the crane operation with less erroneous operation can be performed.

Next, according to a third aspect of the present invention, in the first or second aspect of the present invention, the first operation unit group further includes at least a twist lock operation switch, a spreader tilt switch, and a flipper up / down switch. The second group of operating devices is provided with at least a spreader length selection switch, a spreader oil pump start push button, and a failure reset push button, and an indicator light is further provided on the touch panel so as to be able to change the setting.
Therefore, the same effect as that of the invention according to claim 1 or 2 can be obtained, and an indicator lamp and the like can be allocated to the touch panel.
