Description

  The present invention relates to an operation pattern switching device for a construction machine that switches an operation pattern of an operation lever provided in a construction machine such as a hydraulic excavator and an operation pattern switching system for a construction machine.

  For example, a hydraulic excavator that is one of construction machines includes a lower traveling body, an upper revolving body that is pivotably provided on the lower traveling body, and a boom, arm, and And an articulated front device including a work tool (for example, a bucket, hereinafter simply referred to as a bucket).

  The lower traveling body, the upper swing body, and the front device constitute a driven member of a hydraulic drive device provided in the hydraulic excavator. This hydraulic drive apparatus generally includes a prime mover such as an engine, at least one hydraulic pump driven by the prime mover, and a boom hydraulic cylinder that drives the boom, arm, and bucket by pressure oil discharged from the hydraulic pump. The hydraulic cylinder for the arm, the hydraulic cylinder for the bucket, the traveling hydraulic motor for running the lower traveling body by the pressure oil discharged from the hydraulic pump, and the upper swing body by the pressure oil discharged from the hydraulic pump. A plurality of hydraulic actuators including a turning hydraulic motor for turning the lower traveling body and operating means for operating each of the plurality of hydraulic actuators are provided.

  The operating means are usually a cross-operated manual operation lever located on both the left and right sides of the driver's seat where the operator is seated, and a left / right driving operation lever (operating with his / her feet) located in front of the driver's seat. Possible).

  The manual operation lever is usually designed to operate a turning hydraulic motor, a boom hydraulic cylinder, an arm hydraulic cylinder, and a bucket hydraulic cylinder among the plurality of hydraulic actuators. Originally, there are various patterns for each construction machine manufacturer as to which actuator is to be associated with the operation target in the operation direction of the two operation levers in the left-right direction and the front-rear direction (convenient total of 4 directions). It was. As a unified standard for these various operation patterns, an operation pattern as a JIS standard is defined. According to this operation pattern, the left / right operation of the left operation lever is arm dump / cloud, the left / right operation is turning left / right, the front / rear operation of the right operation lever is lowering / raising the boom, and the left / right operation is bucket It is a cloud dump.

  Accordingly, even each model manufactured by each manufacturer can be applied not only to its own operation pattern but also to the above JIS standard, or even an operator accustomed to the operation pattern of other companies can operate. As described above (especially in the case of rental use, this need is great), there is already known one in which a plurality of operation patterns can be switched.

  As such an operation pattern switching device, there is a conventional one described in, for example, Patent Document 1. This conventional technique switches a plurality of operation patterns when the operation lever is an electric lever method (a method in which the operation amount of the operation lever is detected by a detecting means such as a potentiometer or a sensor and is replaced with an electric signal and output as an operation signal). Is. An electric operation signal from the potentiometer is output to a solenoid portion (electromagnetic proportional valve) of each control valve via a controller (control device). The operation pattern can be switched by the controller switching the destination (each control valve) of each electric operation signal in accordance with the input operation of the rotary operation type operation tool.

Here, since construction machines such as hydraulic excavators are used in harsh outdoor environments due to their properties, repair and replacement of parts and maintenance are performed after manufacture and sale. And since the repair cost of the entire machine (= machine management cost) gradually increases as the machine continues to be used for many years, users originally put out construction machines that have been used for a certain period as trade-in machines It was normal to buy a new machine. However, there are usually many construction sites, such as public works, where construction machines are engaged. Due to the nature of construction work, it is easily affected by social conditions such as economic trends and economic conditions, and as a result, changes in the number of orders placed are significantly changed. For this reason, in recent years, the number of users who have rented appropriately from a rental company is increasing rather than owning construction machines themselves and buying new machines one after another from old ones.
In response to such circumstances, rental companies are desperate to have a large number of machines that can switch a plurality of operation patterns. Further, the types of operation patterns prepared by the rental company are about ten types due to not only the operation patterns of the manufacturers but also the operation patterns according to the user's request.

  On the other hand, in real transactions, each rental company often has a specific user as a customer, and other than about 2 to 4 types of operation patterns used by the customer are not normally used. Limiting the number of operation patterns to various types reduces operation pattern setting errors and facilitates management. However, if it is limited to about 2 to 4 types of specific operation patterns from the beginning, it cannot be switched to an operation pattern that is required for other users other than the customer or for other rental companies. Since inconvenience arises, there is a need for some sort of operation pattern switching function other than the four types. The above prior art has not taken into consideration the limitation of such a plurality of switchable operation patterns, and thus cannot sufficiently meet the above needs.

  An object of the present invention is to provide a construction machine operation pattern switching device and a construction machine operation pattern switching system capable of limiting a plurality of operation patterns that can be switched on the construction machine side to the minimum necessary.

Thereby, the drive signal generation means reads the operation pattern stored in the pattern storage means in response to the setting input by the setting input means, and generates a drive signal for the operation signal from the operation lever device based on this operation pattern. The drive signal is output to the corresponding solenoid valve. Therefore, a plurality of operation patterns can be switched by an input operation of the setting input means provided in the construction machine.

  At this time, for example, when setting a switchable operation pattern of a construction machine used in a rental company or the like, a pattern communication device is connected to the construction machine so as to be able to communicate, and the operation pattern required by the rental company, for example, is used with this pattern communication device. Is input, and the input data is transmitted to the construction machine side. As a result, the rewriting unit of the construction machine receives the operation pattern data input by the pattern communication device, and rewrites the received data into the pattern storage unit. Therefore, the input operation at the pattern communication device can change the setting of a plurality of operation patterns that can be input by the setting input means of the construction machine, and thereby the plurality of operation patterns that can be switched on the construction machine side is minimized. It can be limited to.

Thus, the arm hydraulic cylinder 22 is driven in the contracting direction or the extending direction to dump or cloud the arm 19. Similarly to the above-described operation pattern A, the cross operation type right manual operation lever 36R is operated to the front side or the rear side, so that the boom hydraulic cylinder 21 is driven in the contraction direction or the extension direction and the boom 18 is lowered or raised. By operating the left or right side, the bucket hydraulic cylinder 23 is driven in the extending direction or the contracting direction, and the bucket 20 is clouded or dumped.

In addition, a drive signal for driving the arm 19 and the upper swing body 3 is generated in response to an operation signal generated by operating the right manual operation lever 36R in the front-rear direction and an operation signal generated by operating in the left-right direction. It is output to the 49 electromagnetic proportional valves 49A and 49B and the electromagnetic proportional valves 47A and 47B of the turning control valve 47, respectively. In response to this, the turning control valve 47, the boom control valve 48, the arm control valve 49, and the bucket control valve 50 are switched.

As a result, when the cross operation type left manual operation lever 36L is operated to the front side or the rear side, the boom hydraulic cylinder 21 is driven in the contraction direction or the extension direction to lower or raise the boom 18, and the left side or right side is operated. Thus, the bucket hydraulic cylinder 23 is driven in the contracting direction or the extending direction to dump or cloud the bucket 20. Further, the cross-operating right manual operation lever 37R is operated to the front side or the rear side to drive the arm hydraulic cylinder 22 in the extending direction or the contracting direction to cloud or dump the arm 19 and to operate on the left side or the right side. Thus, the turning hydraulic motor 16 is driven to turn the upper turning body 3 to the left or right.

(4) Operation pattern D
When the predetermined calculation process is performed based on the operation table of the operation pattern D, the controller 52 performs the operation signal by the front / rear operation of the left manual operation lever 36L and the operation signal by the operation of the left / right direction as in the operation pattern C described above. On the other hand, drive signals for driving the boom 18 and the bucket 20 are generated, and these drive signals are output to the electromagnetic proportional valves 48A and 48B of the boom control valve 48 and the electromagnetic proportional valves 50A and 50B of the bucket control valve 50, respectively. The In addition, a drive signal for driving the arm 19 and the upper swing body 3 is generated in response to an operation signal generated by operating the right manual operation lever 36R in the front-rear direction and an operation signal generated by operating in the left-right direction. It is output to the 49 electromagnetic proportional valves 49A and 49B and the electromagnetic proportional valves 47A and 47B of the turning control valve 47, respectively. In response to this, the turning control valve 47, the boom control valve 48, the arm control valve 49, and the bucket control valve 50 are switched.

  As a result, like the operation pattern C described above, the cross operation type left manual operation lever 36L is operated to the front side or the rear side, thereby driving the boom hydraulic cylinder 21 in the contracting direction or the extending direction to lower or raise the boom 18. At the same time, the bucket hydraulic cylinder 23 is driven in the contraction direction or the extension direction by being operated leftward or rightward, and the bucket 20 is dumped or clouded. Further, when the cross operation type right manual operation lever 36R is operated to the front side or the rear side, the arm hydraulic cylinder 22 is driven in the contraction direction or the extension direction, and the arm 19 is dumped or crowded, and the left side or the right side is operated. Thus, the turning hydraulic motor 16 is driven to turn the upper turning body 3 to the left or right.

(5) Operation pattern E
When a predetermined calculation process is performed based on the operation table of the operation pattern E, the controller 52 responds to the operation signal from the front and rear operation of the left manual operation lever 36L and the operation signal from the left and right operation. Drive signals for driving the swing body 3 are generated, and these drive signals are output to the electromagnetic proportional valves 48A and 48B of the boom control valve 48 and the electromagnetic proportional valves 47A and 47B of the swing control valve 47, respectively. In addition, a drive signal for driving the arm 19 and the bucket 20 is generated in response to an operation signal generated by operating the right manual operation lever 36R in the front-rear direction and an operation signal generated by operating in the left-right direction, and these drive signals are generated by the arm control valve 49. Output to the electromagnetic proportional valves 49A and 49B and the electromagnetic proportional valves 50A and 50B of the bucket control valve 50, respectively. In response to this, the turning control valve 47, the boom control valve 48, the arm control valve 49, and the bucket control valve 50 are switched.

  As a result, when the cross operation type left manual operation lever 36L is operated to the front side or the rear side, the boom hydraulic cylinder 21 is driven in the contraction direction or the extension direction to lower or raise the boom 18, and the left side or right side is operated. Thus, the turning hydraulic motor 16 is driven to turn the upper turning body 3 to the left or right. Further, when the cross operation type right manual operation lever 36R is operated to the front side or the rear side, the arm hydraulic cylinder 22 is driven in the contraction direction or the extension direction, and the arm 19 is dumped or crowded, and the left side or the right side is operated. As a result, the bucket hydraulic cylinder 23 is driven in the extending direction or the contracting direction to cloud or dump the bucket 20.

(6) Operation pattern F
When a predetermined calculation process is performed based on the operation table of the operation pattern F, the controller 52 applies the arm 19 and the bucket to the operation signal from the front and rear operation of the left manual operation lever 36L and the operation signal from the left and right operation. 20 are generated and output to the electromagnetic proportional valves 49A and 49B of the arm control valve 49 and the electromagnetic proportional valves 50A and 50B of the bucket control valve 50, respectively. In addition, a drive signal for driving the boom 18 and the upper swing body 3 is generated in response to an operation signal generated by operating the right manual operation lever 36R in the front-rear direction and an operation signal generated by operating in the left-right direction, and these drive signals are used as boom control valves. 48 are output to the 48 electromagnetic proportional valves 48A and 48B and the electromagnetic proportional valves 47A and 47B of the turning control valve 47, respectively. In response to this, the turning control valve 47, the boom control valve 48, the arm control valve 49, and the bucket control valve 50 are switched.

  As a result, the cross operation type left manual operation lever 36L is operated to the front side or the rear side to drive the arm hydraulic cylinder 22 in the contracting direction or the extending direction to dump or cloud the arm 19, and to the left or right side. By being operated, the bucket hydraulic cylinder 23 is driven in the contraction direction or the extension direction, and the bucket 20 is dumped or clouded. Further, when the cross operation type right manual operation lever 36R is operated to the front side or the rear side, the boom hydraulic cylinder 21 is driven in the contraction direction or the extension direction to lower or raise the boom 18, and is operated to the left side or the right side. Thus, the turning hydraulic motor 16 is driven to turn the upper turning body 3 leftward or rightward.

  FIG. 8 is a diagram illustrating details of the operation pattern assignment table stored in the storage unit 61 of the controller 52 as an example.

  FIG. 8 shows which one of the operation patterns A, B, C, D, E, F, and G is assigned to the pattern changeover switches 44a to 44d. In FIG. 8, operation pattern A is assigned to the first pattern changeover switch 44a, operation pattern B is assigned to the second pattern changeover switch 44b, and operation pattern c is assigned to the third pattern changeover switch 44c. The operation pattern D is assigned to the fourth pattern changeover switch 44d. Accordingly, any one of the four operation patterns A to D is set and selected by a signal input from any one of the four pattern changeover switches 44a to 44d.

  Next, detailed control procedures of the controller 52 and the pattern communication device 55 having the above-described configuration will be described. 9 is a flowchart showing the control processing (program) contents of the controller 52, FIG. 10 is a flowchart showing the control processing contents in the operation pattern setting of the controller 52, and FIG. 11 is the control processing of the pattern communication apparatus 55. 12 is a flowchart showing the contents of (program), FIG. 12 is a flowchart showing the contents of control processing in the operation pattern assignment table setting of the pattern communication device 55, and FIG. 13 is the custom pattern (operation pattern) of the pattern communication device 55. It is a flowchart showing the control processing content in the operation table edit of G). 14 is a diagram showing a menu screen displayed on the display unit 56 of the pattern communication device 55, and FIG. 15 shows an operation pattern assignment setting screen displayed on the display unit 56 of the pattern communication device 55. FIG. 16 is a diagram illustrating a custom pattern editing screen displayed on the display unit 56 of the pattern communication device 55.

  In FIG. 9, the controller 52 first determines in step 100 whether the pattern communication device 55 is connected and there is a signal from the pattern communication device 55 that requests transmission of an operation pattern allocation table. If there is a signal for requesting transmission of the operation pattern allocation table, the determination in step 100 is satisfied, and the routine proceeds to step 110. In step 110, the operation pattern assignment table stored in the storage unit 61 is transmitted to the pattern communication device 55. Then, the process proceeds to step 120, where it is determined whether or not an operation pattern assignment table has been received from the pattern communication device 55. If the operation pattern assignment table is received, the determination at step 120 is satisfied, and the routine goes to step 130. In step 130, the received operation pattern allocation table is rewritten in the storage unit 61, and then the process proceeds to step 140. On the other hand, if the operation pattern assignment table is not received in step 120, the determination is not satisfied, and the routine goes to step 140. If there is no signal requesting transmission of the operation pattern allocation table in step 100, the determination is not satisfied, and the routine goes to step 140.

  In step 140, it is determined whether there is a signal requesting transmission of the custom pattern operation table from the pattern communication device 55. If there is a signal requesting transmission of the custom pattern operation table, the determination in step 140 is satisfied, and the routine proceeds to step 150. In step 150, the custom pattern operation table stored in the storage unit 61 is transmitted to the pattern communication device 55. Then, the process proceeds to step 160, and it is determined whether a custom pattern operation table is received from the pattern communication device 55. If the custom pattern operation table is received, the determination at step 160 is satisfied, and the routine goes to step 170. In step 170, the received custom pattern operation table is rewritten in the storage unit 61, and then the operation pattern setting process in step 180 is performed. On the other hand, if the custom pattern operation table is not received in step 160, the determination is not satisfied, and the operation pattern setting process in step 180 is performed. If there is no signal for requesting transmission of the custom pattern operation table in step 140, the determination is not satisfied, and the process proceeds to operation pattern setting processing in step 180.

  In the operation pattern setting process shown in FIG. 10, first, in step 181, it is determined whether any one of the pattern changeover switches 44a to 44d and the signal from the set switch 45 are simultaneously input. If they are input simultaneously, the determination at step 181 is satisfied and the routine goes to step 182. In step 182, a blinking signal is output to the corresponding pattern indicator lamp (any one of 46a to 46d) to blink. Then, the process proceeds to step 183, and it is determined whether or not the state in which the signals from the pattern changeover switch and the set switch 45 are simultaneously input has passed a specified time.

  If the simultaneously input state has passed the specified time, the determination at step 183 is satisfied, and the routine goes to step 184. In step 184, an operation pattern is set based on the operation pattern assignment table stored and held in the storage unit 61 (that is, the operation pattern flag F is rewritten), and the process proceeds to step 185 to send a lighting signal to the corresponding pattern indicator. Output and light up. That is, in the operation pattern allocation table shown in FIG. 8 described above, when the state in which the signals from the first pattern changeover switch 44a and the set switch 45 are simultaneously input exceeds a specified time, the operation pattern flag is set to F = A. (Operation pattern A) is rewritten, and a lighting signal is output to the corresponding pattern indicator lamp 46a to light it.

  In step 186, an operation pattern operation table is read from the storage unit 61 according to the operation pattern flag F, and predetermined calculation processing is performed on the operation signals from the operation lever devices 37L and 37R based on the operation table. The generated drive signal is output to the corresponding electromagnetic proportional valve (47A, 47B to 50A, 50B). When the operation pattern setting process in step 180 is completed, the process returns to step 100 and the same procedure is repeated.

In FIG. 11, when the pattern communication device 55 is turned on, first, in step 200, the menu screen 70 is displayed on the display unit 56 (see FIG. 14, the cursor operation unit 57a and the button operation units 75b and 75c). The menu screen 70 may be called by an input operation or the like). The menu screen 70 displayed on the display unit 56 includes a “button assignment” button 71 and a “custom pattern creation” button 72. The “button assignment” button 71 is operated on the menu screen 70 (for example, after the cursor is moved with the cursor operation unit 57a, the button is clicked with the button operation units 75b and 75c. The same is true for the operations in step S2), and the determination in step 210 is satisfied, and the process proceeds to the allocation table setting process in step 220.

  In the assignment table setting process shown in FIG. 12, first, in step 221, a signal requesting an operation pattern assignment table is transmitted to the controller 52, and the operation pattern assignment table is received from the controller 52. Thereafter, the process proceeds to step 222, and the operation pattern assignment setting screen 73 is displayed on the display unit 56 (see FIG. 15A). The setting screen 73 displays a first pattern allocation area 74a for displaying an operation pattern assigned to the first pattern changeover switch 44a, and a first pattern assignment area for displaying the operation pattern assigned to the second pattern changeover switch 44b. The second pattern assignment area 74b, the third pattern assignment area 74c for displaying the operation pattern assigned to the third pattern changeover switch 44c, and the operation pattern assigned to the fourth pattern changeover switch 44d are displayed. A fourth pattern allocation area 74d, a “return” button 75, and a “write” button 76. At this time, in the pattern allocation areas 74a to 74d, the allocation table of the operation patterns received from the controller 52 in step 221 is displayed.

  In step 223, an operation pattern allocation table is set and input. Specifically, when any one of the pattern assignment areas 74 a to 74 d is operated on the setting screen 73, a selection screen 77 in which the operation patterns A to F and custom (operation pattern G) are listed in the setting screen 73 is displayed. (See FIG. 15B). In FIG. 15B, the second pattern allocation area 74 b is operated to display the selection screen 77, and when “operation pattern B” in the selection screen 77 is further operated, “operation” in the selection screen 77 is displayed. “Pattern B” is highlighted. Thereafter, the selection screen 77 disappears and “operation pattern B” is displayed in the second pattern allocation area 74b (see FIG. 15C).

  When the setting input of the pattern assignment areas 74 a to 74 d is completed on the setting screen 73 and the “write” 76 button is operated, the determination at step 224 is satisfied, and the routine proceeds to step 225. In step 225, the operation pattern assignment table set and input as described above is transmitted to the controller 52, the process proceeds to step 226, and the end screen 78 is displayed on the display unit 56 (see FIG. 15D). The end screen 78 includes an “OK” button 79 and displays, for example, a message prompting the controller 52 to restart. When the “OK” button 79 is operated on the end screen 78, the determination at step 227 is satisfied, and the assignment table setting process at step 220 is ended. Then, it returns to step 200 and repeats the same procedure as the above.

  When the “return” 75 button is operated on the setting screen 73, the determination at step 228 is satisfied, and the assignment table setting process at step 220 ends. Then, it returns to step 200 and repeats the same procedure as the above.

  On the other hand, when the “custom pattern creation” button 72 is operated on the menu screen 70 in FIG. 14, the determination in step 230 in FIG. 11 is satisfied, and the process proceeds to the custom pattern operation table editing process in step 240.

  In the operation table editing process shown in FIG. 13, first, in step 241, a signal requesting a custom pattern operation table is transmitted to the controller 52, and the custom pattern operation table is received from the controller 52. Thereafter, the process proceeds to step 242 where the custom pattern editing screen 80 is displayed on the display unit 56 (see FIG. 16A). The editing screen 80 includes a front operation area 81a, a rear operation area 81b, a left operation area 81c, and a right operation area 81d that display operation objects corresponding to the front direction, the rear direction, the left direction, and the right direction of the left operation lever 36L. And “return” to the front operation area 82a, the rear operation area 82b, the left operation area 82c, and the right operation area 82d for displaying the operation objects corresponding to the front direction, the rear direction, the left direction, and the right direction of the right operation lever 36R, respectively. A button 83 and a “write” button 84 are provided. At this time, in the operation areas 80a to 80d and 81a to 81d, the custom pattern operation table received from the controller 52 in step 241 is displayed.

  In step 243, the custom pattern operation table is edited and input. Specifically, when any one of the operation areas 81a to 81d and 82a to 82d is operated on the editing screen 80, the operation target and the item (none) that does not select the operation direction or the operation target are listed in the editing screen 80. The selection screen 85 is displayed (see FIG. 16B). In FIG. 16B, the right operation area 82d of the right operation lever 36R is operated, the right operation area 82d is highlighted and the selection screen 85 is displayed, and “bucket pull” in the selection screen 85 is displayed. When “” is operated, “bucket pull” in the selection screen 85 is highlighted. Thereafter, the selection screen 85 disappears, and “bucket pull” is displayed in the right operation area 82d of the right operation lever 36R. Similarly, when “bucket push” is operated on the selection screen 85 displayed by operating the left operation region 82c of the right operation lever 36R, “bucket push” is displayed in the left operation region 82c of the right operation lever 36R ( (Refer FIG.16 (c)).

  When the editing input of the operation areas 81 a to 81 d and 82 a to 82 d is finished on the editing screen 80 and the “write” button 84 is operated, the determination at step 244 is satisfied, and the routine proceeds to step 245. In step 245, the operation table of the custom pattern that has been edited and input is transmitted to the controller 52, the process proceeds to step 246, and an end screen 78 is displayed on the display unit 56 (see FIG. 16D). When the “OK” button 79 is operated on the end screen 78, the determination in step 247 is satisfied, and the custom pattern operation table editing process in step 240 ends. Then, it returns to step 200 and repeats the same procedure as the above.

  Further, when the “return” 83 button is operated on the editing screen 80, the determination in step 248 is satisfied, and the assignment table setting process in step 240 ends. Then, it returns to step 200 and repeats the same procedure as the above.

In the above, the pattern changeover switches 44a to 44d and the set switch 45 are permanently installed in the construction machine described in the claims, and input an instruction to select any one of a plurality of pre-edited operation patterns. Configure possible setting input means.

Next, the operation and effect of this embodiment will be described.
For example, when a rental company or the like sets an operation pattern of a hydraulic excavator to be lent according to a user, the operator tries to change the operation target in each operation direction of the manual operation levers 36L and 36R to the operation pattern desired by the user. When any one of the changeover switches 44a to 44d and the set switch 45 are input simultaneously, the corresponding indicator lamp (any one of 46a to 46d) blinks. When the operator continues the simultaneous input operation of the pattern changeover switch and the set switch 45 for a specified time, the controller 52 sets the operation pattern based on the operation pattern allocation table stored and held in the storage unit 61, and displays the corresponding display. The light comes on. Then, the controller 52 reads the operation table from the storage unit 61 in accordance with the set operation pattern, generates a drive signal for the operation signal from the operation lever devices 37L and 37R based on the operation table, and outputs this drive signal. Output to the corresponding proportional solenoid valve (47A, 47B to 50A, 50B). Therefore, it is possible to switch to four operation patterns (in the operation pattern allocation table stored in the storage unit 61 of the controller 52) by selecting operations of the four pattern changeover switches 44a to 44d provided in the hydraulic excavator. .

  At this time, for example, when setting a switchable operation pattern (that is, one of operation patterns A to G) of a hydraulic excavator used in a rental company or the like, for example, a manufacturer's serviceman or the like communicates with the controller 52 of the hydraulic excavator, for example. The pattern communication device 55 is communicably connected via the wiring 54, and the operation pattern assignment table stored and held in the storage unit 61 of the controller 52 is displayed on the display unit 56 of the pattern communication device 55. Then, the service person sets and inputs, for example, an operation pattern (assignment table) required by the rental company using the pattern communication device 55, and transmits the input data to the controller 52. As a result, the controller 52 receives the operation pattern assignment table from the pattern communication device 55 and rewrites the received assignment table in the storage unit 61. Therefore, the input operation at the pattern communication device 55 can change the setting of four operation patterns that can be input by the hydraulic excavator pattern change-over switches 44a to 44d, thereby increasing the number of operation patterns that can be switched at the hydraulic excavator side. Both can be limited to four necessary minimums.

  In the above-described embodiment, the operation directions of the left / right manual operation levers 36L and 36R of the cross operation type and the turning hydraulic motor 16, the boom hydraulic cylinder 21, the arm hydraulic cylinder 22, and the bucket hydraulic cylinder 23 are used. The operation patterns in which the operation directions are associated with each other are described, and the configuration in which the operation table of the custom pattern (operation pattern G) is edited by the pattern communication device 55 has been described as an example. However, the present invention is not limited to this. That is, for example, a combination of the swing operation pedal 28R and the operation direction of the swing hydraulic cylinder 17 to be operated may be added to the operation pattern, and such an operation table may be edited by the pattern communication device 55. FIG. 17 is a diagram illustrating a custom pattern editing screen displayed on the display unit 56 of the pattern communication device 55 in such a modification. Note that FIG. 17 corresponds to FIG. 16A of the above-described embodiment, and equivalent parts are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  The custom pattern editing screen 80 ′ in this modification includes a left operation area 86 a and a right operation area 86 b for displaying operation objects corresponding to the left depression direction and the right depression direction of the swing operation pedal 28 R, respectively. . Even if this operation area 86a or 86b is operated (for example, the cursor is moved by the cursor operation unit 57a and then clicked by the button operation units 75b and 75c), the selection screen 85 ′ ( Although not shown, “Swing left and Swing right are added in addition to the above contents” is displayed, and the custom pattern operation table is edited as in the above embodiment. Also in such a modification, the same effect as the above-described embodiment can be obtained.

  In the above embodiment, the swing-type hydraulic excavator has been described as an example. However, the present invention is not limited to this, and it goes without saying that the present invention may be applied to, for example, an offset-type hydraulic excavator. Further, in the offset hydraulic excavator, as in the above-described modification, the operation target corresponding to the left depression direction and the right depression direction of the offset operation pedal is displayed on the custom pattern editing screen in the pattern communication device 55. A left operation area and a right operation area may be added. In this case, the same effect as described above can be obtained.

  In the above-described embodiment, pattern display lamps 46a to 46d corresponding to the changeover switches 44a to 44d are provided as display means of the hydraulic excavator, and the pattern display lamps corresponding to the set pattern changeover switches are turned on. Although described as an example, the present invention is not limited to this. That is, for example, a liquid crystal display device or the like that displays a set operation pattern as characters may be provided so that the type of the operation pattern is directly recognized. In this case, the same effect as described above can be obtained.
