Shovel

Abstract

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an attachment provided on the upper turning body, an operation part configured to output an operation signal indicating a received operation direction as an electric signal, and a control device configured to perform drive control of at least one of the upper turning body or the attachment of the shovel in accordance with the operation signal. The control device is configured to acquire, from a storage, an operation pattern in which an operation direction receivable by the operation part is associated with drive control to be performed in response to an operation in the operation direction being received, and is configured to switch the operation pattern for performing the drive control, in accordance with a predetermined operation received while a condition for restricting movement of the shovel is satisfied.

What is claimed is: 
     
         1 . A shovel comprising: 
 a lower traveling body;   an upper turning body turnably mounted on the lower traveling body;   an attachment provided on the upper turning body;   an operation part configured to output an operation signal indicating a received operation direction as an electric signal; and   a control device configured to perform drive control of at least one of the upper turning body or    the attachment of the shovel in accordance with the operation signal, wherein the control device is configured to acquire,   from a storage, an operation pattern in which an operation direction receivable by the operation part    is associated with drive control to be performed in response to an operation in the operation direction being received, and the control device is configured to switch the operation pattern for performing the drive control, in accordance with a predetermined operation received while a condition for restricting movement of the shovel is satisfied.   
     
     
         2 . The shovel according to  claim 1 , wherein the control device is configured to, in a case where a stop control of supply of electric power from a power source of the shovel is performed after the 
       operation pattern is switched to a given operation pattern, perform drive control in accordance with the given operation pattern, to which the operation pattern is switched before the stop control is 
        performed, when the supply of the electric power from the power source of the shovel is restarted. 
     
     
         3 . The shovel according to  claim 1 , further 
        comprising:a switch mechanism configured to output, to the control device, a signal indicating whether the predetermined operation is received, wherein the control device is configured to switch the 
  operation pattern in a case where a signal indicating that the predetermined operation is received is input into the control device from the switch mechanism. 
 
     
     
         4 . The shovel according to  claim 3 , wherein the switch mechanism includes a plurality of switch circuits each configured to switch a connection terminal when the predetermined operation 
        is received, and in a case where the control device determines that there is an abnormality in the switch mechanism based on signals from the plurality of switch circuits included in the switch mechanism, the 
        control device is configured to perform the drive control in accordance with the operation pattern selected before determining that there is the abnormality. 
     
     
         5 . The shovel according to  claim 3 , wherein the control device is configured to, in a case where a 
        signal indicating that the predetermined operation is performed a plurality of times within a predetermined period of time, determine that the predetermined operation is performed once and switch the operation pattern. 
     
     
         6 . The shovel according to  claim 3 , wherein the switch mechanism is configured to receive a different operation from the predetermined operation 
        before receiving the predetermined operation, and is configured such that the predetermined operation is receivable in a case where the different operation is received. 
     
     
         7 . The shovel according to  claim 1 , wherein the control device is configured to determine whether the condition is satisfied based on at least one of a position of a gate lock lever or an operating 
        condition of an engine. 
     
     
         8 . The shovel according to  claim 1 , wherein, 
       in an operation pattern stored in the storage, drive controls of the upper turning body and the attachment are allocated to respective operation directions of the operation part, and 
       the control device is configured to switch the 
       drive controls allocated to the respective operation directions of the operation part when the operation pattern is switched. 
     
     
         9 . The shovel according to  claim 8 , wherein the attachment includes a boom attached to the upper turning body, an arm attached to the boom, and an end attachment attached to the arm, 
       and, in an operation pattern stored in the storage, 
       drive controls of the boom, the arm, and the end attachment are allocated to respective operation 
        directions. 
     
     
         10 . The shovel according to  claim 1 , wherein, 
       when the operation pattern is switched, the control 
        device causes a display device to display a message indicating that the operation pattern is switched. 
     
     
         11 . The shovel according to  claim 3 , wherein 
        each time the switch mechanism receives the predetermined operation, the control device switches among three or more operation patterns in accordance with an order in which the three or more operation patterns are stored in the storage. 
     
     
         12 . The shovel according to  claim 3 , wherein the switch mechanism is provided at a position 
       farther from an operator of the shovel than the operation part is.
