[Specific implementation method]

[0018] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0019] like Figures 1-6 As shown, in this embodiment, a crawler lifting work machine includes a frame 1, a crawler walking device 2, a power unit 3, a speed transmission device 4, a hydraulic system 5, a rotating and swinging device 6, a lifting device 7, a working platform 8, and a control device 9. The crawler walking device 2 is arranged on the left and right sides of the frame 1, and the power unit 3 is arranged above the right rear position of the frame 1. The speed transmission device 4 is arranged behind the power unit 3 and is mounted on the frame 1 by screws. The rotating and swinging device 6 is mounted at the middle position behind the frame 1 through a hinge shaft. The lifting device 7 is composed of a parallelogram structure formed by a movable arm 71 and a long connecting rod 72 installed inside the movable arm. One end of the lifting device 7 is assembled and connected to the hinge point of the swinging and rotating device 6, and the other end of the lifting device 7 is assembled and connected to the hinge point of the working platform 8.

[0020] Among them, in this embodiment, the crawler walking device 2 is installed on the supporting wheel U-shaped mounting frame 11 of the frame 1, and the supporting wheel U-shaped mounting frame 11 is installed with multiple supporting wheels 21. A track tensioning mechanism 22 is arranged in front of the supporting wheel U-shaped mounting frame 11. A driving wheel 23 is arranged on the top of the rear of the crawler walking device 2 and is spline-connected to the speed transmission device 4. The crawler 24 is respectively installed on the driving wheel 23, the supporting wheel 21, and the guide wheel 25 and they are connected together to form the crawler walking device 2.

[0021] In this embodiment, a counterweight 12 is installed on the U-shaped mounting frame 11 of the supporting wheel of the frame 1, which is beneficial to the stability of the crawler lifting machine.

[0022] In this embodiment, the speed change transmission device 4 adopts an asymmetric design, and the left shaft tube 41 is longer than the right shaft tube 42. This makes it easier for the rotating and swinging device 6 to be installed in the middle position behind the frame 1, and the structure is more compact.

[0023] In this embodiment, a fruit frame limiting frame 13 is arranged on the upper left side of the frame 1 to facilitate the placement and limiting of the fruit frame 14.

[0024] The operating principle of the crawler lifting machine of this application is explained as follows:

[0025] First, start the power unit 3. Since the double-groove pulley of the power unit 3 is connected to the pulley of the speed transmission device 4 and the pulley of the hydraulic pump 52 of the hydraulic system 5 through belts, the power unit 3 drives the hydraulic pump 52 to start working. If the reversing valve does not work, the hydraulic oil returns to the oil tank through the pressure relief valve. By controlling the valve core of the boom reversing valve 53 to move left or right, the extension and retraction of the boom cylinder 56 can be controlled, thereby controlling the rise or fall of the working platform 8. By controlling the valve core of the swing reversing valve 54 to move left or right, the extension and retraction of the swing cylinder 55 can be controlled, thereby controlling the left or right rotation of the working platform 8.

[0026] Since a tensioner is arranged under the belt connecting the double-groove pulley of the power unit 3 and the pulley of the speed transmission device 4, when the work machine needs to move forward or backward, the forward gear or reverse gear is engaged respectively. At this time, when the clutch handle is tightened, the tensioner tightens the belt connecting the double-groove pulley of the power unit 3 and the pulley of the speed transmission device 4, thereby transmitting power to the speed transmission device 4, and then to the work machine crawler walking device 2, thereby driving the work machine forward or backward.

[0027] The above description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore, it should not be understood as limiting the scope of protection of the present invention.
