Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0020] Please see Figures 1-4A winch-driven lifting platform device includes a chassis frame 1, a scissor lift assembly 2 inside the chassis frame 1, and a loading platform 3 on the top surface of the scissor lift assembly 2; a winch 4 is located at the center of one side of the chassis frame 1, a winch rope 43 is mounted on the winch 4, a motor assembly 41 is located on one side of the winch 4, a connecting beam 24 is located below one side of the scissor lift assembly 2, a pin bracket 25 is mounted on the connecting beam 24, pins 26 are connected between the pin brackets 25, and a pull ring 42 is located at the other end of the winch rope 43. Shaft 26 is connected to pull ring 42; by installing scissor lift assembly 2 inside chassis frame 1, scissor lift assembly 2 can be raised and lowered inside chassis frame 1, thereby driving the lifting and lowering of cargo platform 3, and can be folded inside chassis frame 1; by pulling winch 4 to pull winch rope 43, the length of winch rope 43 outside winch 4 is changed, and winch rope 43 is connected to pull ring 42, thereby pulling connecting beam 24 to move, and by pulling connecting beam 24 to move, the angle of scissor lift assembly 2 is changed, thereby realizing the raising and lowering of scissor lift assembly 2.

[0021] Please see Figures 1-4 The chassis frame 1 has a groove 14 inside the slot. The bottom surface of the scissor lift assembly 2 has an axle 21 on one side and a pulley 22 on the other side. The pulley 22 is located inside the groove 14. A pair of first hinge frames 15 are provided on the side of the chassis frame 1 that is perpendicular to the groove 14. The bottom surface of the scissor lift assembly 2 is hinged to the first hinge frame 15. The winch 4 pulls the connecting beam 24 at the bottom of the scissor lift assembly 2, causing the pulley 22 on the outside of the connecting beam 24 to move inside the groove 14, so that one end of the scissor lift assembly 2 moves horizontally. The first hinge frame 15 is hinged to the other end of the bottom surface of the scissor lift assembly 2, which assists the pulley 22 in moving horizontally inside the groove 14, thereby maintaining the horizontal upward movement of the loading platform 3.

[0022] Please see Figures 1-4 A pair of second transfer frames 31 are provided on one side of the bottom surface of the loading platform 3. The other end of the connecting beam 24 at the bottom of the scissor assembly 2 is hinged to the second transfer frame 31. During the movement of the pulley 22 at the bottom of the scissor assembly 2 inside the slide groove 14, the top of the scissor assembly 2 and the loading platform 3 are rotated relative to each other through the second transfer frame 31, so as to keep the loading platform 3 horizontally raised and lowered.

[0023] Please see Figures 1-4A pair of guide frames 32 are provided on the other side of the bottom surface of the loading platform 3. A connecting beam 24 is provided between the bottom end of the scissor assembly 2 and the top of the other end of the first hinge frame 15. A wheel axle 21 and a roller 23 are provided on the opposite side of the top of the scissor assembly 2. The roller 23 contacts the top surface of the guide frame 32. By changing the angle of the scissor assembly 2, the roller 23 at the top of the scissor assembly 2 slides on the bottom surface of the guide frame 32. The guide frame 32 is "L" shaped. The vertical ends of the two guide frames 32 are arranged opposite each other to limit the two sides of the guide frame 32.

[0024] Please see Figures 1-4 A battery 5 is installed at one end of the winch 4, and a protective cover 6 is installed on the outside of the battery 5. Multiple switches are installed on the top surface of the protective cover 6. The switches include a power switch, a lifting switch, and a lowering switch. The lifting switch controls the motor assembly 41 to work, winding its own rope in the forward direction. The inner angle of the scissor assembly 2 decreases, driving the cargo platform 3 to rise. After reaching the required height, the lifting switch is pressed again to stop lifting. After the lowering switch is turned on, the motor assembly 41 runs in the reverse direction, and the tension of the winch 43 on the scissor assembly 2 decreases, causing the cargo platform 3 to gradually fall back to the initial position under the action of gravity. The power switch is turned on to power the battery 5 to the lifting switch and the lowering switch.

[0025] Please see Figures 1-4 The top surface of the chassis frame 1 is provided with a handrail 11, and the two sides of the handrail 11 are attached to the outer sides of the two ends of the chassis frame 1. The winch 4 is coaxially arranged with the motor assembly 41, and the winch 4 is parallel to the side of the chassis frame 1. The center of the side of the handrail 11 coincides with the axis of the winch 4. A wheel frame 12 is provided at the top of the bottom surface of the chassis frame 1, and a wheel 13 is provided inside the wheel frame 12. The chassis frame 1 is moved by the wheel frame 12 and the wheel 13. The chassis frame 1 is moved by the handrail 11. The handrail 11 and the protective cover 6 cooperate with each other to protect the winch 4 and the battery 5.

[0026] During use, place the goods to be lifted on the loading platform 3, turn on the power switch to connect the lifting and lowering switches, and then turn on the lifting switch. The motor assembly 41 will start working, causing the winch 4 to wind its own rope 43 in the forward direction, pulling the scissor assembly 2 to move to the right, causing the pulley 22 to move within the slide groove 14. The inner angle of the scissor assembly 2 will decrease, driving the loading platform 3 to rise. Once the required height is reached, press the lifting switch again to stop lifting. When the lowering switch is turned on, the scissor assembly 2 will move in the opposite direction, and the loading platform 3 will eventually fall back to the initial position.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
