DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, a lifting platform mechanism includes a mounting frame 1, a movable platform 8 and a lifting and folding mechanism; the movable platform 8 is arranged on both sides of the mounting frame 1; the lifting and folding mechanism is arranged at both ends of the movable platform 8; the mounting frame 1 is composed of square tubes 11 connected;

[0025] The lifting and folding mechanism includes a power device 2, a reversing reducer 21, a rotating shaft 23, a first slider 3, a support rod 4, a second slider 5 and a folding rod 6; the reversing reducer 21 is arranged at both ends of the top of the mounting frame 1, the output end of the power device 2 is connected to the reversing reducer 21, the rotating shaft 23 is arranged inside the square tube 11, and the top of the rotating shaft 23 is connected to the reversing reducer 21; a connecting rod 22 is arranged between the reversing reducer 21 on the same side as the mounting platform. The reversing reducer 21 is driven to operate by the power device 2, and the rotating shaft 23 is driven to rotate inside the square tube 11 by the reversing reducer 21, wherein the transmission is realized by the meshing of gears inside the reversing reducer 21, and the co-operation of the reversing reducer 21 and the connecting rod 22 ensures that the rotating shafts 23 on both sides of the movable platform 8 can rotate synchronously.

[0026] The side wall of the square tube 11 is provided with a slide groove 111; the first slider 3 is slidably arranged in the slide groove 111, and one end of the first slider 3 is connected to the rotating shaft 23, and the other end is hinged to the support rod 4; the second slider 5 is arranged on the side wall of the square tube 11 and is located below the first slider 3, one end of the folding rod 6 is hinged to the second slider 5, and the other end is hinged to the support rod 4, and the two ends of the movable platform 8 are respectively arranged on the support rod 4;

[0027] By rotating the rotating shaft 23, the first slider 3 can be driven to move up and down. When the second slider 5 is fixed, the support rod 4 and the folding connection can be used to fold the movable platform 8. This folding function allows the lifting platform mechanism to be folded up when not in use, reducing the occupied area and facilitating storage and transportation. When the second slider 5 is unrestricted, when the first slider 3 drives the movable platform 8 to move upward, the second slider 5 can be manually supported to rise synchronously with the movable platform 8. After adjusting the appropriate height, the second slider 5 can be fixed, and the height of the movable platform 8 can be adjusted to meet different work requirements, and the scope of application is wider.

[0028] First pulleys 31 are disposed on both sides of the first sliding block 3 , and the first pulleys 31 are slidably disposed on the outer side wall of the square tube 11 .

[0029] By providing the first pulley 31, the friction between the first slider 3 and the square tube 11 is effectively reduced, and the wear caused by the friction is reduced, so that the first slider 3 moves up and down more smoothly, the service life of the first slider 3 and the square tube 11 is extended, and the maintenance cost is reduced.

[0030] An inspection escalator 7 is provided between adjacent installation frames 1 .

[0031] The inspection and transport escalator 7 is provided to provide a convenient and safe passage for the staff, so that they can move freely between the installation frames 1 at different heights, thereby conveniently carrying out the inspection, maintenance and upkeep of the lifting platform.

[0032] A mounting block 81 is disposed at the bottom of the movable platform 8 , and the mounting block 81 is fixedly disposed on the support rod 4 .

[0033] The movable platform 8 is fixed to the support rod 4 by the mounting block 81, which can ensure the stability of the movable platform 8 during the lifting process.

[0035] The second pulley 32 slides along the inner wall of the square tube 11, providing a clear guide for the slider, further reducing the friction on the basis of the first pulley 31. This makes the path of the slider more stable and accurate during the lifting process, which helps to improve the accuracy and stability of the lifting platform.

[0036] The working principle of the utility model is as follows: the reversing reducer 21 is driven by the power device 2 to operate, and the rotating shaft 23 is driven to rotate. The connecting action of the connecting rod 22 ensures that the rotating shafts 23 on both sides of the movable platform 8 can rotate synchronously under the drive of the power device 2. The first slider 3 can be driven to move up and down through the rotation of the rotating shaft 23, and then the movable platform 8 can be driven to move; when the second slider 5 is fixed, the folding work of the movable platform 8 can be realized through the connection and cooperation between the support rod 4 and the folding. After the second slider 5 is released from the restriction, when the first slider 3 drives the movable platform 8 to move upward, the second slider 5 can be manually supported and raised synchronously with the movable platform 8. After adjusting the appropriate height, the second slider 5 is fixed, and the height of the movable platform 8 can be adjusted to meet different work requirements, and the scope of application is wider.
