Description
Technical Field
The application relates to the technical field of hoisting, in particular to a vertical hoisting device for a working arm of an excavator.
Background
The excavator is used as an earthmoving machine widely applied in modern engineering machinery, has the advantages of strong practicability, convenience in operation and the like, and a working device of the excavator is often replaced by different accessories in the use process so as to realize different operation functions. The hoisting is a commonly used function of the excavator.
The utility model discloses a lifting device of an excavator in the specification of the utility model with the publication number of CN206857962U, and the technical scheme is that limiting devices allowing lifting ropes to pass through are arranged at the edges of two sides of a bucket of the excavator, and the ends of the lifting ropes are bound with suspended objects. The lifting hook structure is arranged on a bucket and a quick-change device which are commonly used on the excavator, so that lifting can be realized, but the common lifting structure cannot realize vertical lifting of the excavator arm, a lifting piece can do arc motion along with the bucket, and meanwhile, the lifting height is very low, and the operation range height is small.
Disclosure of utility model
In order to increase the lifting height of the excavator and realize vertical lifting at the same time, the application provides a vertical lifting device for a working arm of the excavator.
The application provides a vertical lifting device for a working arm of an excavator, which adopts the following technical scheme:
The vertical lifting device for the working arm of the excavator comprises a winch, a pulley and a pull rope, wherein the winch is connected to the middle section of the working arm, the rotation axis of the winch is arranged along the width direction of the working arm, the pulley is rotatably connected to the tail end of the working arm, the rotation axis of the pulley is arranged along the width direction of the working arm, one end of the pull rope is fixedly connected to the winch in a winding mode, and the other end of the pull rope is erected on the pulley and provided with a hook.
Optionally, an installation seat is fixedly connected to the tail end of the working arm, and the pulley is rotationally connected to the installation seat.
Optionally, two parallel pins are arranged on the mounting seat, and mounting holes for the two pins to pass through are formed in the working arm.
Optionally, a roller is rotatably connected to the mounting seat, a rotation axis of the roller is arranged along the width direction of the working arm, and a gap for the pull rope to pass through is reserved between the roller and the pulley.
In summary, the application has the following beneficial technical effects:
According to the application, through the arrangement of the winch and the pull rope, when the rope is used, the rope for binding the hanging piece is hung on the hook, similar to the state in the background technology, and then the winch is started to wind the pull rope, so that the hanging piece is vertically hoisted, the hoisting height can be increased until the length of the pull rope is influenced, and the operation range height is effectively increased.

Detailed Description
The application is described in further detail below with reference to fig. 1-2.
The embodiment of the application discloses a vertical lifting device for a working arm 1 of an excavator, which comprises a winch 2, a pulley 7 and a pull rope 3, wherein the winch 2 is fixedly connected to the middle section of the working arm 1, the rotation axis of a winding roller in the winch 2 is arranged along the width direction of the working arm 1, the tail end of the working arm 1 is fixedly connected with a mounting seat 4 through two parallel pin shafts 5, the pulley 7 is rotationally connected to the mounting seat 4, the rotation axis of the pulley 7 is arranged along the width direction of the working arm 1, meanwhile, the peripheral surface of the pulley 7 is provided with a groove 71 matched with the pull rope 3, one end of the pull rope 3 is wound and fixedly connected to the winding roller of the winch 2, and the other end of the pull rope 3 is erected on the pulley 7 and fixedly connected with a hook 8.
When the hoisting device is used, a rope for binding the hoisting piece is hung on the hook 8, like an excavator in the background art, and then the winch 2 is started to wind the pull rope 3, so that the hoisting piece is vertically hoisted, the hoisting height can be raised until the length of the pull rope 3 is influenced, and the operation range height is effectively improved.
In order to prevent the pull rope 3 from being separated from the pulley 7, the installation seat 4 is also rotationally connected with a rotating roller 6, the rotating axis of the rotating roller 6 is arranged along the width direction of the working arm 1, a gap for the pull rope 3 to pass through is reserved between the rotating roller 6 and the pulley 7, and the pull rope 3 is clamped in the gap to avoid separation.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
