[0002] DMX lifting platforms are electric lifting devices controlled by the DMX512 digital communication protocol. DMX lifting platforms are lifting machines that vertically transport people or goods and are widely used in logistics, manufacturing, construction and other fields. Their core function is to achieve efficient and safe vertical transportation through hydraulic or electric systems.

[0003] However, most traditional DMX lifting platforms only have guardrails and usually lack body safety belt anchor points. When the platform tilts or falls due to overload, mechanical failure or operational error, people may be thrown off the platform due to inertia, causing a fall from a height accident. Even if the platform does not fall completely, sudden shaking or sudden stop may cause people to collide with the edge of the platform, equipment or surrounding structures, causing injuries such as fractures and concussions. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional DMX lifting platforms only have guardrails and usually lack body safety belt anchor points. When the platform tilts or falls due to overload, mechanical failure, or operational errors, personnel may be thrown off the platform due to inertia, causing high-altitude fall accidents. This utility model proposes a fall protection mechanism for DMX lifting platforms.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fall prevention mechanism for a DMX lifting platform, including a lifting mechanism, a manned platform fixedly connected to the top of the lifting mechanism, an extension plate fixedly connected to one side of the manned platform, and a fixing structure provided on one side of the extension plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a fall protection mechanism for a DMX lifting platform. (Refer to...) Figures 1 to 3 A fall protection mechanism for a DMX lifting platform includes a lifting mechanism 1, a manned platform 2 fixedly connected to the top of the lifting mechanism 1, an extension plate 3 fixedly connected to one side of the manned platform 2, and a fixing structure 4 provided on one side of the extension plate 3. The fixed structure 4 includes a connecting seat 41, one side of which is fixedly connected to one side of the extension plate 3. A vertical rod 42 is fixedly connected to one side of the connecting seat 41, a horizontal rod 43 is fixedly connected to the top of the vertical rod 42, a ball seat 44 is fixedly connected to one side of the horizontal rod 43, a ball 45 is rotatably connected to the inner cavity of the ball seat 44, a first connecting rod 46 is fixedly connected to the surface of the ball 45, a special-shaped sleeve 47 is rotatably connected to one end of the first connecting rod 46, a second connecting rod 48 is slidably connected to the inner cavity of the special-shaped sleeve 47, and a fixing strap 49 is fixedly connected to one end of the second connecting rod 48. In the fall protection mechanism of this DMX lifting platform, the lifting mechanism 1 can drive the person-carrying platform. Platform 2 is raised and lowered. Existing differential gears and other reduction mechanisms can be installed in the lifting mechanism 1 to minimize the risk of platform 2 falling directly to the ground if the lifting mechanism 1 malfunctions. The fixing structure 4 is connected to the extension plate 3 via the connecting seat 41. The upright 42 and the crossbar 43 extend the fixing strap 49 to the top of the platform 2 in an L-shape. The fixing strap 49 can fix the waist of the personnel. The fixing strap 49 is connected via the second connecting rod 48 and the special-shaped sleeve 47. The special-shaped sleeve 47 can rotate along the first connecting rod 46. The ball 45 and the ball seat 44 cooperate to facilitate the movement of personnel on the platform 2, ensuring their flexibility while fixing them.

[0018] Reference Figure 4 One end of the second connecting rod 48 is fixedly connected to a limiting plate 410. A damping telescopic rod 411 is fixedly connected to one side of the limiting plate 410. One end of the damping telescopic rod 411 is fixedly connected to the inner wall of the irregular sleeve 47. A first spring 412 is sleeved on the surface of the damping telescopic rod 411. One end of the first spring 412 is fixedly connected to one side of the limiting plate 410, and the other end of the first spring 412 is fixedly connected to the inner wall of the irregular sleeve 47. Through the damping telescopic rod 411 and the first spring 412, when the manned platform 2 falls, the personnel's bodies will be lifted upward due to inertia. At the same time as being lifted, the fixing belt 49 can drive the second connecting rod 48 and the limiting plate 410 to be lifted upward. When the limiting plate 410 is lifted upward, it will squeeze the damping telescopic rod 411 and the first spring 412, improve the buffering effect, and ensure that the personnel are stable on the manned platform 2.

[0019] Reference Figure 4 A second spring 413 is sleeved on the surface of the second connecting rod 48. One end of the second spring 413 is fixedly connected to one side of the limiting plate 410, and the other end of the second spring 413 is fixedly connected to the inner wall of the special-shaped sleeve 47. With the second spring 413, when the manned platform 2 falls, the personnel's bodies will be lifted upward due to inertia. While squeezing the damping telescopic rod 411 and the first spring 412, the second spring 413 can be stretched, further improving the buffering effect and ensuring that the personnel are stable on the manned platform 2.

[0020] Reference Figure 3A top plate 414 is fixedly connected to one side of the irregular sleeve 47, and a first buffer layer 415 is fixedly connected to one side of the top plate 414. Through the top plate 414, the top plate 414 can limit the range of the person's head and try to avoid the person's head from colliding with the irregular sleeve 47 when it moves upward due to inertia. The first buffer layer 415 can be made of thickened rubber or sponge material to try to avoid serious impact when the person's head comes into contact with the top plate 414.

[0021] Reference Figure 5 A second buffer layer 5 is fixedly connected to one side of the manned platform 2, a footboard 6 is fixedly connected to one side of the second buffer layer 5, and a fixing member 7 is fixedly connected to one side of the footboard 6. With the footboard 6 and the fixing member 7, when the manned platform 2 falls accidentally or after a fall, the feet of the personnel can be placed on the footboard 6. The U-shaped fixing member 7 can fix the feet of the personnel. The second buffer layer 5 can be composed of springs and thickened rubber, which can cushion the legs of the personnel when falling.

[0022] Reference Figure 5 A guard plate 8 is fixedly connected to one side of the manned platform 2, and a third buffer layer 9 is fixedly connected to one side of the guard plate 8. Through the guard plate 8, the guard plate 8 can protect the personnel on the manned platform 2 and try to avoid throwing the personnel directly out of the manned platform 2 when the manned platform 2 falls accidentally. In addition, the third buffer layer 9 can try to avoid serious collision between the limbs of the personnel and the guard plate 8.

[0023] Working principle: The lifting mechanism 1 can drive the personnel platform 2 to rise and fall. The lifting mechanism 1 can be equipped with existing differential gears or other reduction mechanisms to minimize the risk of the personnel platform 2 falling directly to the ground in case of a malfunction. The fixing structure 4 is connected to the extension plate 3 via the connecting seat 41. The upright 42 and crossbar 43 form an L-shape to extend the fixing strap 49 above the personnel platform 2. The fixing strap 49 can secure the waist of the personnel. The fixing strap 49 is connected via the second connecting rod 48 and the special-shaped sleeve 47. The special-shaped sleeve 47 can rotate along the first connecting rod 46. The ball 45 and ball seat 44 cooperate to facilitate the free movement of personnel on the personnel platform 2, ensuring both personnel fixation and flexibility. When the personnel platform 2 falls, the personnel's body will rise due to inertia. Simultaneously, the fixing strap 49 can drive the second connecting rod 48 and the limiting plate 410 to rise. As the limiting plate 410 rises, it will compress the damping telescopic rod 411 and the first spring 412. To improve the cushioning effect, the second spring 413 can be stretched while the damping telescopic rod 411 and the first spring 412 are compressed, further improving the cushioning effect and ensuring that the personnel are stable on the manned platform 2. The top plate 414 can limit the range of the personnel's head, and try to avoid the personnel's head from colliding with the special sleeve 47 when the personnel's head is thrown upward due to inertia. The first buffer layer 415 can be made of thickened rubber or sponge material to try to avoid serious impact when the personnel's head comes into contact with the top plate 414. When the manned platform 2 falls accidentally or after the fall, the personnel's feet can be placed on the footplate 6. The U-shaped fastener 7 can fix the personnel's feet. The second buffer layer 5 can be composed of springs and thickened rubber, which can cushion the personnel's legs when falling. The guard plate 8 can protect the personnel on the manned platform 2, and try to avoid the personnel being thrown directly off the manned platform 2 when the manned platform 2 falls accidentally. The third buffer layer 9 can try to avoid serious impact between the personnel's limbs and the guard plate 8.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
