Abstract

(57) [Summary] (Correction) [Purpose] To provide a control lever that enables highly efficient and accurate operation of work machines such as power shovels without requiring skill. [Structure] A structure in which a grip 1 that rotates back and forth is interlocked with an arm 2 via a hinge, an arm 3, and an operating mechanism, and an interlocking type control that grips the grip and operates a bucket portion of a power shovel in the same movement direction. -It is a lever.

Description

[Detailed description of the device]   (A) Industrial application fields The present invention is a hydraulic excavator car, a tractor excavator, other bucket parts, and An interlocking type controller that allows remote control of other parts such as hydraulic breakers for attachment parts. It relates to a control lever (stick) unit.   (B) Conventional technology Conventional hydraulic excavators and other control levers operate at one location, such as a bucket Operate back and forth with one upright lever to move back and forth to push back the hydraulic valve Basically, at present, one lever generally operates two systems back and forth. And the left and right cross shapes, for example, by operating the front and rear levers of the right hand, Rotate the arm up and down, move the arm forward and backward in the left and right directions, and move the left and right levers forward and backward. Boom up / down operation, left / right operation, etc. The main structure is one that operates 4 systems of operation (total of 8 strokes) with a bar. Has to operate the control of the bucket with both hands forward, backward, left and right. The operation directions of the lever and bucket do not match, making it difficult to grasp the sense of direction It requires skill and cannot obtain high efficiency and accuracy.   (C) Issues that the device tries to solve The purpose of the present invention is to solve the above drawbacks and to enable easy, accurate and highly efficient operation. It is what   (D) Means for solving the problem In order to solve the above problems, according to the present invention, as shown in FIGS. For the grip (1) and arm (2) for the bucket (1 ″) of the pressure shovel Hinge the lever arm (3) to the lever arm (2) and boom (3 ″) Joints), grip part (1), lever arm (2), Directly (wire cable etc.) or indirectly (electrical control etc.) independent from (3) Also, a hydraulic opening / closing mechanism is provided and configured.   (E) Action Grasp the grip (1) in Fig. 1 and 2 and turn it forward and downward (counterclockwise in side view). The hydraulic valve to the bucket cylinder (1 ″) opens and the bucket (1 ″) moves in the same direction ( Rotate counterclockwise as shown in Fig. 3) and move the grip upward (clockwise in side view) If turned, the bucket cylinder will receive hydraulic pressure in the opposite direction and the bucket (1) will move upward ( Rotate clockwise (in the figure), then push the grip (1) forward to move the lever arm. The arm (2 ″) is activated by the hydraulic pressure applied to the arm cylinder (2 ″). The bucket and bucket operate forward, and if you pull the grip toward you, the arm and bar The ket acts in the front direction, and if you raise the grip upwards, the lever The boom (3) is activated, hydraulic pressure is applied to the boom cylinder (3 ″), and the boom (3 ″) ) Others operate in the upward direction, and if lowered in the same direction, the boom, arm, bar The ket part operates downward.   (F) Example     Example 1. FIG. 1 shows the first embodiment. FIG. 3 is a perspective view showing the example, which is an example applied to a hydraulic excavator.     Example 2. Figures 4 and 5 show an example of applying the present invention to a tractor shovel. As shown in FIG. 5, the bucket is a bucket (1 ″) that rotates back and forth, and an arm that moves up and down ( 2 "), the grip (1) for the bucket (1") and the arm (2 ″) Actuated, it consists of a lever arm (2), and the grip (1) moves up and down. Then, the bucket will move up and down, and by operating the grip part up and down, the arm and The bucket moves up and down.     Example 3. If a grip opening (1) is equipped with a hydraulic opening / closing switch, etc. Operation of hydraulic components such as hydraulic breakers and clippers is accurate and highly efficient. You can make it.   (G) Effect of devising The interlocking control lever of the present invention can be operated with one hand to operate the grip part, Angle, front and back, up and down and a series of multiple operations at the same time, smoothly projected in the same direction, Prompt and easy to operate, accurate and highly efficient, the bucket attachment The operation of hydraulic breakers such as components, clippers, etc. can be significantly improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the first embodiment of the present invention. FIG. FIG. 2 is a side view showing the operation state. FIG. 3 is a side view of the hydraulic excavator showing its operating state. FIG. 4 shows the second embodiment. The side view which shows the operation state of the example applied to the tractor shovel. FIG. 5 is a side view of the tractor shovel showing its operating state. (1) is a grip part, (2) is a lever arm that operates an arm (2 ″), (3) is a lever arm that operates a boom (3 ″), and (H) is a hinge part (joint).

Claims (1)

[Scope of utility model registration request] 1. For a plurality of bucket parts (1 ″), arms (2 ″), booms (3 ″), etc. to be operated, a grip part (1) provided with an operation mechanism in each part of the same shape, a lever arm (2),
