DETAILED DESCRIPTION
[0018] Embodiment one
[0019] As Figs. 1-3As shown in the figure, the portable lifting device for elevator maintenance proposed in this embodiment includes a mounting frame 1, a scissor lift assembly 5, and a lifting plate 6. The mounting frame 1 is L-shaped and is provided with a moving assembly 4 and multiple placement blocks 2. The moving assembly 4 and the multiple placement blocks 2 are located on different end faces. The mounting frame 1 is also provided with a damped sliding movable handle 3. The scissor lift assembly 5 is mounted on the mounting frame 1 and is connected to the output end of the drive assembly. The lifting plate 6 is located at the output end of the scissor lift assembly 5.
[0020] In this embodiment, the user pulls out the movable handle 3 and moves the device to the desired position with the moving component 4. Then, the multiple placement blocks 2 are all in contact with the ground. The user moves onto the lifting plate 6, and the control drive component drives the scissor lift component 5 to push the lifting plate 6 up until the user moves to the appropriate position. The lifting plate 6 is made of hard plastic to reduce the overall weight of the device and improve its portability. The scissor lift component 5 can be stacked to reduce the space occupied, thereby reducing the difficulty of transporting the device.
