[0041] Example 1

[0042] See also Figure 1-Figure 2 This embodiment provides a lifting platform with a movable rotating arm to solve the problem of low work efficiency of existing manual material handling.

[0043] In this embodiment, the movable lifting platform of the rotating arm includes a column 20 fixedly connected to the base 10, and a rotating drum 40 is rotatably mounted on the column 20, and the rotating drum 40 is fixedly connected to the cantilever 30. The lifting rope 51 wound on the winch 50 is guided to the end of the cantilever 30 through the steering wheel 32. A rotatable screw 25 is provided inside the column 20, and the screw 25 is meshed and connected with a handle 23 penetrated on the column 10. A sliding sleeve 27 is screwed on the outside of the screw 25, and a pin 28 is provided on the outer wall of the sliding sleeve 27, which is engaged with the avoidance groove 26 on the column 10, and the pin 28 is engaged with the sliding groove 41 obliquely arranged on the inner wall of the rotating drum 40.

[0044] In this embodiment, the winch 50 pulls the lifting rope 51 to move to lift the material, and the handle 23 drives the screw rod 25 to rotate, and the sliding engagement between the pin 28 and the slide groove 41 drives the rotating drum 40 to rotate around the column 20, so as to rotate the cantilever 30 to the target position, thereby realizing the transportation of the material, and has the advantage of simple operation.

[0045] It should be noted that a moving wheel 11 is provided on the base 10, so that the overall movement of the hoisting platform is more convenient. The column 20 is vertically welded to the surface of the base 10, the cantilever 30 is arranged vertically with the column 20 as a whole, the rotating drum 40 is rotatably sleeved on the outside of the column 20 as a whole, and a diagonal brace 31 is welded between the cantilever 30 and the rotating drum 40. At the same time, a positioning cylinder 22 is fixedly connected to the end of the cantilever 30, and the positioning cylinder 22 is rotatably sleeved on the outside of the column 20, and the positioning cylinder 22 is arranged above the rotating drum 40. , limit rings 21 are welded on the columns 20 on the upper and lower sides of the rotating drum 40, and the limit rings 21 are used to limit the rotating drum 40 on the columns 20. The winch 50 is installed at the lower end of the column 20, and the lifting rope 51 is coiled on the winch 50. One end of the lifting rope 51 is guided to the end of the cantilever 30 after passing around the guide wheel 32 on the cantilever 30, and the end of the lifting rope 51 is provided with a hook 52 for hooking materials. As an example, the winch 50 is an electric winch, and the winch 50 is used to reel in the lifting rope 51, so as to lift the material hooked by the hook 52.

[0046] In addition, a support plate 24 for accommodating the screw 25 is welded inside the column 20. Two support plates 24 are arranged inside the column 20. The screw 25 is rotatably locked on the two support plates 24 as a whole. The screw 25 is coaxially arranged with the column 20 as a whole. A coaxially arranged bevel gear 251 is welded at the lower end of the screw 25. At the same time, a driving gear 231 is welded at the inner end of the handle 23. The axis of the driving gear 231 remains perpendicular to the axis of the column 20. The handle 23 drives the driving gear 231 to rotate, thereby driving the screw 25 to rotate.

[0047] In addition, the sleeve 27 is screwed onto the outside of the screw rod 25, and a pin 28 is welded on the outer wall of the sleeve 27, and the pin 28 is arranged along the radial direction of the column 20. An avoidance groove 26 is provided on the outer wall of the column 20, and the extension direction of the avoidance groove 26 remains parallel to the axis of the column 20. The pin 28 is slidably engaged in the inside of the avoidance groove 26 as a whole, and the outer end of the pin 28 extends to the outside of the column 20 and is slidably engaged with the slide groove 41 formed on the inner wall of the rotating drum 40. The slide groove 41 is constructed as an elliptical structure extending along the inner wall of the rotating drum 40, and the axis of the slide groove 41 remains inclined relative to the axis of the column 20.

[0048] It should be understood that, by utilizing the sliding engagement between the pin 28 and the avoidance groove 26, the sleeve 27 is only allowed to slide along the axial direction of the column 20, thereby preventing the sleeve 27 from rotating inside the column 20; by utilizing the sliding engagement between the pin 28 and the slide groove 41, the axial sliding of the pin 28 can drive the rotating drum 40 to rotate around the column 20, thereby driving the cantilever 30 to rotate.

[0049] When in use, the winch 50 is first used to pull the lifting rope 51 to lift the material, and then the handle 23 is rotated to drive the screw 25 to rotate inside the column 20, and drive the rotating drum 40 to rotate around the column 20, so as to rotate the cantilever 30 to the target position to realize the lifting of the material.

[0050] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
