[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 4 As shown in the figure, a lifting device for logistics handling equipment according to an embodiment of the present invention is provided. The lifting body 1, used for lifting logistics goods, includes a lifting assembly 2, a fixing plate 3, and an anti-fall assembly 4. The lifting assembly 2, fixing plate 3, and anti-fall assembly 4 are all mounted on the lifting body 1. The lifting assembly 2 includes a positive and negative lead screw 21, a lead screw slider 22 that is driven by a helical pair with the positive and negative lead screw 21, and a lifting plate 24. The outer wall surface of the lifting plate 24 is connected to a first fixing frame 23 and a second fixing frame 24 respectively via a first fixing rod and a second fixing rod. 5. Rotary connection, the shaft end of the positive and negative lead screw 21 is mounted on the motor 26, the lifting plate 24 is used to support the fixed plate 3, the anti-fall assembly 4 includes a receiver 42 and a push plug 43 that is slidably connected to the inner wall of the receiver 42, the outer wall of the push plug 43 is fixedly connected to a push rod 44, the push rod 44 is used to support the fixed plate 3, the outer wall of the receiver 42 is also fixedly connected to a one-way valve 46 for air intake and exhaust and a sealing plug 47, the force of the push plug 43 to move, to draw air into or exhaust air into the receiver 42.

[0020] In practical application of this utility model embodiment, the motor 26, through the positive and negative lead screws 21 and the lead screw slider 22, causes the first fixed frame 23 to be subjected to force, which lifts the fixed plate 3 through the lifting plate 24, thereby simultaneously lifting the logistics items on the fixed plate 3 for easy stacking. At the same time, the lifting of the fixed plate 3 causes the push rod 44 to pull the push plug 43. Due to the action of the one-way valve 46, air is drawn into the storage container 42 until the lifting plate 24 moves to the maximum distance. At this point, the push rod 44 and the storage container 42 are in a perpendicular state to the lifting body 1. The air inside the storage container 42 supports the push rod 44 through the push plug 43, preventing the lifted goods from falling.

[0021] By setting up the lifting component 2, the force exerted by the movement of the lead screw slider 22 can apply force to the fixed plate 3, thereby lifting the logistics items. Compared with hydraulic rod lifting, this reduces the maintenance cost of the lifting equipment and eliminates the problem of hydraulic oil leakage. Furthermore, by setting up the anti-fall component 4, air can be drawn in while lifting the items, and the air pressure can support the fixed plate 3, thus preventing damage to the lifting equipment and the lifted items from falling and being damaged.

[0022] like Figure 1 As shown, as a further embodiment of the present utility model, the end face of the lifting body 1 is rotatably connected to a caster wheel 11, the outer wall of the lifting body 1 is fixedly connected to a support plate 12, and the outer wall of the support plate 12 is fixedly connected to a handle 13.

[0023] In practical applications, this utility model embodiment facilitates the movement of the lifting equipment, so that when it is not necessary to lift the items, it does not interfere with the space of the logistics warehouse.

[0024] like Figure 2 and Figure 3 As shown, as a further embodiment of the present utility model, the end face of the motor 26 is fixedly installed on the lifting body 1, and the inner wall of the lifting body 1 is provided with a limiting groove 14 for limiting the stroke of the lead screw slider 22. The outer wall of the positive and negative lead screw 21 is also fixedly connected with a fixing ring 27 for limiting the stroke of the lead screw slider 22.

[0025] Specifically, as a further embodiment of this utility model, the first fixing frame 23 is fixedly installed on the end face of the lead screw slider 22, and the second fixing frame 25 is fixedly installed on the free end of the fixing plate 3;

[0026] In practical application of this utility model embodiment, the lifting stroke of the lifting plate 24 is limited by the setting of the first fixing frame 23 and the second fixing frame 25, so that the lifting of the fixing plate 3 is more stable. Moreover, the limiting groove 14 and the fixing ring 27 can also limit the stroke of the lead screw slider 22, which can prevent the fixing plate 3 from tipping over when lifted too high.

[0027] like Figure 2 and Figure 3 As shown, in a further embodiment of the present utility model, a counterweight plate 31 is fixedly connected to the end face of the fixed plate 3, and a positioning block 32 is fixedly connected to the free end of the fixed plate 3. The outer wall surface of the positioning block 32 is inserted into the lifting body 1.

[0028] In practical application of this utility model embodiment, the counterweight plate 31 can support the fixed plate 3 to prevent the weight of the lifted item from being too large, which could cause one section of the lifting body 1 to tilt.

[0029] like Figure 2 and Figure 3 As shown, as a further embodiment of the present utility model, the anti-fall component 4 also includes a first support frame 41 fixedly connected to the inner wall of the lifting body 1 and a second support frame 45 fixedly connected to the free end of the fixing plate 3. The storage device 42 is rotatably connected to the lifting body 1 through the first support frame 41, and the push rod 44 is rotatably connected to the fixing plate 3 through the second support frame 45.

[0030] In practical application of this utility model embodiment, the first support frame 41 and the second support frame 45 are used to support and limit the storage device 42 and the push rod 44, thereby drawing in air by moving the push plug 43, supporting and limiting the fixed plate 3, increasing the safety of lifting the item, and facilitating the storage of the anti-fall component 4.

[0031] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
