  The work table 21 is provided with a joystick-type operation lever device 30 for driving the turning drive device 6, the hoisting cylinder 8, the telescopic cylinder 9, the swing drive device 11 and others.

  The joystick-type operation lever device 30 is pivoted to a base 31 including a support mechanism and a tilt detection mechanism of a shaft portion 40 that is attached to be tiltable so as to protrude upward, the shaft portion 40, and a distal end portion 43 of the shaft portion 40. It has a grip portion 50 that can be attached.

  The shaft portion 40 includes a lower shaft portion 41 attached to be pivotable in the front-rear direction and the left-right direction by a pivot bearing attached in the base 31, and a lower shaft portion in a tilting surface of the lower shaft portion 41 including a distal end portion 43. The upper shaft portion 42 is bent in the direction away from the operator. The bent portion of the lower shaft portion 41 and the upper shaft portion 42 may be configured by bending the shaft portion 40 of a single member, or by joining a plurality of members of the lower shaft portion 41 and the upper shaft portion 42. It may be configured.

  Further, the respective tilt angles (tilt amounts in the claims) of the shaft portion 40 in the front-rear direction and the left-right direction are detected by the first potentiometer 61 and the second potentiometer 62 attached to the base 31, and each tilt direction and each tilt are detected. A detection signal corresponding to the angle is output to the control device 65, the hoisting cylinder 8 is driven by the control signal output from the control device 65 according to the detection signal of the first potentiometer 61, and the boom 7 moves up and down. The telescopic cylinder 9 is driven by the control signal output from the control device 65 in accordance with the detection signal of the potentiometer 62, and the boom 7 is expanded and contracted.

  The shaft portion 40 is urged in a direction in which the tilt displacement of the shaft portion 40 returns to the original by an urging spring or the like provided in the base 31, and an operator's hand is moved from the shaft portion 40 in the tilted state. When separated, the shaft portion 40 is configured to automatically return to the neutral position of the original vertical state.

  In addition, the grip 50 is configured in two upper and lower stages, that is, an upper grip part 51 and a lower grip part 52, and the lower grip part 52 is disposed on the same axis as the central axis of the shaft 40 and rotates with respect to the shaft 40. It is mounted movably. The lower grip 52 has a cylindrical shape on the inside and a polygonal shape on the outside, and the outer shape has a shape slightly larger than that of the upper grip 51.

  Further, in the space between the lower grip portion 52 and the upper shaft portion 42, the rotation direction and the rotation angle (the rotation amount in the claims) of the lower grip portion 52 are detected, and a detection signal corresponding to the rotation angle is generated. A third potentiometer 63 that outputs to the control device 65 is attached. The boom 7 is configured to turn by the control device 65 in accordance with the detection signal of the third potentiometer 63.

  An upper return mechanism and a lower return mechanism are connected to the upper grip portion 51 and the lower grip portion 52, which restrict these rotation ranges and automatically return them to their original neutral positions.

  The operation lever device 30 is disposed on the posture maintaining member 10 side of the work table 21 and in a recess 23 that is recessed from the upper edge 22 of the work table 21. The recess 23 prevents the unintentional operation of the work machine from occurring when the operation lever 32 tilts when a part other than the operator's hand, a work member, a tool, or the like touches the operation lever 32 during the work. The upper end portion 53 of the grip portion 50 is deeper than the upper edge 22.

  Next, the operation of the operation lever device 30 described above will be described.

  First, the aerial work vehicle X travels and is carried into the work site, and stops at an appropriate place as an installation place. Then, the outrigger 4 is operated to jack up the wheel 3 so that the wheel 3 is separated from the ground and the vehicle body 2 is substantially horizontal.

  When the jack-up is completed, the operator gets on the work table 21 and attaches the safety belt, and then operates the operation lever device to operate the boom 7 to move the work table 21 to the work target place and bring it closer. At this time, the operator operates the boom 7 as desired by tilting the shaft portion 40 while holding the grip portion 50 or rotating the lower grip portion 52 around the shaft portion 40. By the tilting operation of the shaft portion 40, the boom 7 performs the undulation operation or the expansion / contraction operation individually or simultaneously, and the boom 7 is turned by the rotation operation of the lower grip portion 52.

  With the configuration as described above, in the tilting operation of the shaft portion 40 having the grip portion 50, particularly the pulling operation in the direction approaching the operator, the vicinity of the base of the thumb does not hit the wall 24 on the operator side of the recess 23. At the same time, it is not necessary to bend the wrist towards you.

  Therefore, the pull operation in the direction approaching the operator has an effect that the degree of freedom of operation is not lost.

  Furthermore, since the operation of bending the wrist toward the front is reduced as much as possible, it is possible to reduce the difficulty of the operation and making the fingers and wrist easy to get tired as much as possible. It is.

  Further, when the lower grip portion 42 is rotated around the upper shaft portion 42, even if the vicinity of the base of the thumb is rotated toward the operator side, the vicinity of the base of the thumb remains on the operator side wall 24 of the recess 23. The result was that there was no loss of freedom of operation.

  In the above description, the third potentiometer 63 is attached to the space between the lower grip portion 52 and the upper shaft portion 42, but is attached to the base end side adjacent to the grip portion 50 of the upper shaft portion 42. It may be a thing. According to these configurations, in any case, the third potentiometer 63 can be provided in a range integral with the lower grip portion 52, and the operation lever device 30 can be configured compactly. is there.

  Further, although the tilt signal detection means and the rotation signal detection means have been described as the first, second, and third potentiometers 61, 62, and 63, they may be added with a neutral position detection limit switch.

  Next, FIG. 2 shows a second embodiment of the operating lever device of the working machine according to the present invention. Reference numeral 44 denotes a box-shaped member.

  The box-shaped member 44 is interposed between the lower shaft portion 41 and the upper shaft portion 42 of the shaft portion 40, and the upper shaft portion 42 includes the tip portion 43 and within the tilting surface of the lower shaft portion 41. On the other hand, the tip end side is bent in a direction away from the operator. A third potentiometer 63 is attached to the internal space of the box-shaped member 44. As in the first embodiment, the third potentiometer 63 detects the rotation direction and rotation angle of the lower grip 52 and outputs a detection signal corresponding to the rotation direction and rotation angle to the control device 65. Accordingly, the boom 65 is configured to turn by the control device 65.

  The box-shaped member 44 may have any shape such as a rectangular parallelepiped or a cylinder as long as the third potentiometer 63 can be attached to the internal space.

  Further, the transmission of the rotation operation of the lower grip portion 52 to the third potentiometer 63 may be performed by making the upper shaft portion 42 into a pipe shape and disposing a transmission member such as a shaft in the hollow portion.

  Since it comprised in this way, the effect | action that the cross section of the bending part of the upper shaft part 42 and the lower shaft part 41 expanded and an intensity | strength improved was acquired.

  In addition, the mounting position of the third potentiometer 63 can be secured, and since it is housed in the bent portion with improved strength, it is possible to obtain an effect that it is safer against a collision with the outside.

  Next, FIG. 3 shows a third embodiment of the operating lever device of the working machine according to the present invention. 45 is a protrusion extension part.

  The protruding extension portion 45 is a portion in which the base end portion side of the upper shaft portion 42 passes through the bending position and protrudes and extends linearly, and the third potentiometer 63 is disposed at the protruding and extended end portion.

  As for the transmission of the rotation operation of the lower grip 52 to the third potentiometer 63, the upper shaft portion 42 may be formed in a pipe shape and a transmission member such as a shaft may be disposed in the hollow portion as in the second embodiment.

  Since it comprised in this way, the effect that the restriction | limiting of the attachment / accommodation part of the 3rd potentiometer 63 itself or the 3rd potentiometer 63 can be made small was acquired.

  By the way, such an operating lever device 30 may be provided with an enable switch that needs to be operated and maintained in advance prior to tilting or rotating the operating lever 32.

  For example, in Japanese Patent Laid-Open No. 10-97334, this enable switch is mounted on the upper surface of the upper grip portion and pushed downward, and in Japanese Patent Laid-Open No. 2002-318628, the side surface on the side opposite to the operator of the upper grip portion is operated. It is designed to be operated by being pushed to the operator side.

  However, at the mounting position of these enable switches, like the operation lever device of the working machine according to the present invention, the upper shaft in which the tip side of the lower shaft portion 41 is bent away from the operator in the tilting surface of the lower shaft portion 41. The operation lever 32 including the portion 42 is difficult to operate.

  Therefore, it is conceivable that the enable switch 70 is attached to the side surface on the operator side of the upper grip portion 51 as shown in FIG.

  With such a configuration, when operating the enable switch 70, when the tilting operation is performed by pushing the operation lever 32 toward the non-operator side, the operation switch 32 is pushed from the diagonally upper side toward the diagonally lower side and operated to the operator side. When the tilting operation is performed by pulling the lever 32, the lever 32 can be operated by being pushed substantially horizontally from the near side to the non-operator side.

  Therefore, the operation of the enable switch 70 can be easily performed regardless of the tilting direction of the operation lever 32, and the degree of operation by bending the wrist toward the front can be made as small as possible.

  Further, if an enable switch other than the enable switch 70 is attached at a different position and any one of the enable switches is operated, the operation lever 32 can function, so that a further effect can be expected.

  Further, since the operation lever device 30 is disposed in the concave portion 23 that is recessed from the upper edge 22 of the work table 21, snow may accumulate in the concave portion 23 during the operation during snowfall, and subsequent operations may be difficult. .

  Therefore, it is conceivable to attach a cover 80 that covers the recess 23. However, the cover 80 that is retracted when operating the operation lever 32 or the like provided in the recess 23 should not hinder these operations. Further, the retracted cover 80 should not hinder the operation of the jib or winch provided on the posture maintaining member 10 side.

  Therefore, as shown in FIG. 1, it is conceivable that the cover 80 is configured to be foldable by connecting a plurality of plate-like members with hinges and retractable to the posture maintaining member 10 side. It is also conceivable to make the cover 80 a slide type.

  With the cover 80 configured as described above, the dimensions in the front-rear direction and the height direction can be reduced at the retracted position, the operation of the operation lever 32 or the like is not hindered, and the operation of the jib or winch is not hindered. Is obtained. In the case of the cover 80 like the latter, if the retracted position is set to the work table 21 side along the upper edge 22, an effect that the cover 80 can be used as a work table can be obtained. The cover 80 may be formed of a single plate.

  In the above description, the operation lever device for a work vehicle according to the present invention has been described as being applied to an aerial work vehicle, but of course, it can be applied to an operation lever device for a work device such as a crane or an excavator. is there.
