Definitions

• the invention relates to the operation pattern switching device of the hydraulic drilling machine, and in particular, the operating pattern of the operating machine operating reporter for the hydraulic drilling machine. -Make changes to match the operator to the operator.
• the hydraulic excavator 1 has a work machine 15 composed of a boom 12, a arm 13 and a bucket 14 as shown in Fig. 3 (a).
• the hydraulic pressure control device 5 is controlled, and the hydraulic oil is supplied to the boom 12, the arm 13, ⁇ , ⁇ -: ' Boom cylinders 18 and arm cylinders 9 installed in 14 and rotation 18 18, No-ket device 10 and rotation motor
• the work machine 15 sent to 11 is a mechanism that can be driven in accordance with the operator's operation reno. Therefore, as shown in FIG.
• the operator has two operation levers_1a and 1b, that is, the operation pattern Up and down movement of the system, and digging of the arm. Operation, digging of a socket, dumping operation, He is fully proficient in all eight left and right turning motions, and works well with complex 'movements.
• the operation of the operating machine by the operation of the two operating levers 1a and 1b is the same, but as shown in Fig. 4.
• the operation pattern of the operation lever differs depending on the machine. This is not a problem if the determined vehicle is operated at all times, but if one hydraulic excavator is used with multiple operators, or if there is a difference in If a single operator uses multiple hydraulic excavators, the operating patterns of the operating levers on each side may be different if the operating patterns are different. Therefore, it is very difficult to use, and the work efficiency is reduced, and at the same time, the operation may cause trouble.
• the invention of the present invention focuses on the above-mentioned problems and aims to easily change the operation pattern of the hydraulic excavator in accordance with the operator's skillful operation pattern.
• Hydraulic drilling that does not cause problems with work efficiency and trouble due to differences from the operator's trained operation pattern Model of machine
• the hydraulic pressure control device and the hydraulic pressure control device that control the operation of the working machine, such as the boom, arm, and bucket rotation, are included in the replacement device.
• the operation input device for inputting instructions for moving the work machine to the operation input device, the operation input device power, and the instruction pattern for the operation input device
• the hydraulic pressure control corresponding to the working stroke is controlled by the hydraulic pressure control described above.
• the control device and the input The combination of the operation of the input device and the correspondingly driven working machine, which is located between the device and the U-troof device. No, 0 turn It is composed of a pattern switching means, which can be set to a pattern, and a power, which can be set at will.
• the display device of the operation pattern set by the pattern switching means can be installed. In the method, the contact points corresponding to each pattern are arranged in multiple rows in the circumferential direction, and this is switched by a rotary switch and a reno. It is possible to make a structure that can be replaced.
• the operation of the operation lever can be performed only by switching the operation pattern switching device installed in the driver's seat. Even if the patterns are different, it is important to adapt the movement of the work machine to your own operation pattern, so that The operator can also operate with his / her own most trained operation. Work efficiency In addition to the above, it is possible to prevent the occurrence of troubles caused by erroneous operation due to inexperience. Brief description of drawings
