[0022] Reference Figure 1-Figure 4 The utility model provides a lifting manned platform with a protective mechanism, including a frame body 1, a socket that can be connected to a universal wheel is provided at the bottom of the frame body 1, and a manned board 6 is slidably connected to the four corners of the frame body 1. A power mechanism is provided on the top of the frame body 1 to drive the manned board 6 to move. The four corners of the manned board 6 are fixed with fixing rods 8 by bolts, and one side of the plurality of fixing rods 8 is provided with a guardrail 5, and at least one guardrail 5 is rotatably connected to the fixing rod 8, and the remaining guardrails 5 are fixed to the fixing rod 8. A limiting mechanism for fixing the movable guardrail 5 is provided on the top of the fixing rod 8, and one side of the plurality of fixing rods 8 is welded with a hanging ring 7. A person can hang a safety rope on the hanging ring 7 to protect the person. The person opens the movable guardrail 5 and stands on the manned board 6. The manned board 6 is driven upward by the power mechanism. In the process of the manned board 6 moving upward, the person can hold the guardrail 5 by hand to stabilize the body and avoid falling from the manned platform and getting injured, thereby improving the protective effect of the device.

[0023] Among them, the limiting mechanism includes a card block 12, which is rotatably connected to the top of the fixed rod 8 through a hinge, a positioning groove 15 is provided at the bottom of the card block 12, and an avoidance groove 11 is provided on one side of the movable guardrail 5. A positioning block 18 is welded on one side of the avoidance groove 11, and the positioning groove 15 matches the positioning block 18. A positioning mechanism for blocking the card block 12 is provided on the top of the movable guardrail 5. The card block 12 is rotated to disengage the positioning groove 15 from the positioning block 18, and then the movable guardrail 5 can be rotated, which is convenient for people to get on and off the loading platform 6, thereby improving the convenience of the device.

[0024] Among them, the positioning mechanism includes a slide groove 17, which is opened on the top of the movable guardrail 5. A slide 13 is slidably connected in the slide groove 17, and one end of the slide 13 is in contact with the block 12. An inclined surface is opened on the end of the slide 13 in contact with the block 12. A spring 16 is welded on one side of the slide 13, and the spring 16 is fixed to the slide groove 17. A limit frame 14 is welded on the top of the movable guardrail 5, and the slide 13 slides in the limit frame 14. One end of the slide 13 is pulled by hand to make the other end of the slide 13 disengage from the block 12, so that the block 12 can rotate, block the block 12, and prevent the block 12 from rotating, thereby further improving the protection effect of the device.

[0025] Among them, the power mechanism includes multiple winches 3, and the multiple winches 3 are fixed to the top inner wall of the frame 1 by bolts. A pull rope 4 is provided at one end of the multiple winches 3, and one end of the pull rope 4 is fixed to the manned board 6. When the winch 3 is started, the winch 3 reels the pull rope 4, thereby enabling the manned board 6 to move upward.
