[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the present invention provides a cargo loading and unloading handling device, the specific contents of which are as follows:

[0017] This invention, through motor control, raises the lifting frame to a suitable height. When the insert plate is inserted into the bottom of the goods, the double-headed hydraulic rod operates, driving the toothed plates on both sides to retract simultaneously. This causes the toothed plates to drive the gears to rotate, which in turn causes the side plates on both sides of the lifting frame to unfold simultaneously via a rotating shaft. This expands the usable space of the lifting frame and prevents the side plates from obstructing the handling of goods. After the goods are lifted, the double-headed hydraulic rod controls the rotating shaft to rotate in the opposite direction, causing the side plates to rotate and press against the sides of the goods, limiting the goods from tipping over when they are stacked high. This protects the goods during handling and improves the overall performance.

[0018] In this invention, after the lifting frame lifts the goods via the insert plate, the double-headed hydraulic rod controls the rotating shaft to rotate. When the side plate rotates and abuts against both sides of the goods, the side plate drives the support plate to rotate together and contact the goods. This causes the spring to be compressed, and the restoring force generated by the spring abuts against both sides of the goods. This can support goods of different widths and also provide cushioning and shock absorption, preventing the goods from shaking and hitting the side plate during transportation, thus further improving the protection of the goods.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0028] Please see Figures 1 to 4 A cargo loading and unloading handling device includes a fixed frame 1, a motor 2 mounted inside the fixed frame 1, and a lead screw 3 fixedly connected to the output end of the motor 2.

[0029] The outer end of the lead screw 3 is threadedly connected to a threaded connecting block 4. The end of the threaded connecting block 4 away from the fixed frame 1 is connected to a lifting frame 5. The lifting frame 5 is fixed with a slider 6 at the end corresponding to the threaded connecting block 4. The fixed frame 1 is provided with a groove 7 at the end corresponding to the slider 6. The slider 6 is slidably connected in the groove 7.

[0030] Two insert plates 8 are welded and fixed at the end of the lifting frame 5 away from the threaded connecting block 4. A double-headed hydraulic rod 9 is fixed at the top of the lifting frame 5. Both ends of the double-headed hydraulic rod 9 are connected to toothed plates 10. The outer end of the toothed plates 10 is meshed with a gear 11. A rotating shaft 12 is fixedly connected to the middle of the bottom end of the gear 11. The rotating shaft 12 is mounted on the rotating frame at the side end of the lifting frame 5. The rotating shaft 12 and the rotating frame at the side end of the lifting frame 5 are rotatably connected. The outer end of the rotating shaft 12 is connected to a side plate 13. A support plate 15 is provided on the inner side of the side plate 13. The support plate 15 is connected to the side plate 13 through an elastic connection mechanism.

[0031] After the lifting frame 5 is raised to a suitable height by the motor 2, when the insert plate 8 is inserted into the bottom of the goods, the double-headed hydraulic rod 9 works to drive the toothed plates 10 on both sides to retract simultaneously. This causes the toothed plates 10 to drive the gears 11 to rotate, which in turn causes the gears 11 to drive the side plates 13 on both sides of the lifting frame 5 to unfold simultaneously through the rotating shaft 12. This expands the usable space of the lifting frame 5 and prevents the side plates 13 from obstructing the handling of goods. After the goods are lifted, the double-headed hydraulic rod 9 controls the rotating shaft 12 to rotate in the opposite direction, causing the side plates 13 to rotate and press against the sides of the goods, limiting the movement of the goods and preventing them from tipping over when they are stacked high. This protects the goods during handling and improves the overall performance.

[0032] Please see Figures 2 to 3 The cross-sections of slider 6 and slide groove 7 are T-shaped and matched. A polished layer is provided between slider 6 and slide groove 7. By setting the cross-sections of slider 6 and slide groove 7 to be T-shaped and matched, slider 6 and slide groove 7 are not easily separated. By setting the polished layer, the friction between slider 6 and slide groove 7 is reduced, making slider 6 move more smoothly in slide groove 7. The cross-section of insert plate 8 is L-shaped, and two insert plates 8 are symmetrically arranged on both sides of the bottom end of lifting frame 5.

[0033] Please see Figure 2 and Figure 4A spring 14 is connected between the side plate 13 and the support plate 15. A guide rod 16 is connected to one end of the support plate 15 near the side plate 13. The guide rod 16 passes through the side plate 13. The spring 14 is made of stainless steel and has a wear-resistant layer on its outer end. By making the spring 14 of stainless steel, corrosion of the spring 14 can be avoided after long-term use. The wear-resistant layer increases the wear resistance of the spring 14 and extends its service life. The guide rod 16 extends out from the inside of the side plate 13. A guide rod groove is opened through the side plate 13 at the position corresponding to the guide rod 16. The guide rod 16 is slidably connected to the side plate 13 through the guide rod groove. By setting the guide rod 16 and extending it out from the inside of the side plate 13, the movement direction of the support plate 15 can be limited to prevent the movement direction of the support plate 15 from deviating.

[0034] Working principle: When using this type of cargo loading and unloading handling device, such as Figures 1 to 4 As shown, firstly, the motor 2 drives the lead screw 3 to rotate. The lead screw 3, through the threaded connection with the threaded connecting block 4, drives the lifting frame 5 to move. After the lifting frame 5 is raised to a suitable height, when the insert plate 8 is inserted into the bottom of the goods, the double-headed hydraulic rod 9 works to drive the toothed plates 10 on both sides to retract simultaneously. This causes the toothed plates 10 to drive the gear 11 to rotate, which in turn causes the gear 11 to drive the side plates 13 on both sides of the lifting frame 5 to unfold simultaneously through the rotating shaft 12, thereby expanding the usable space of the lifting frame 5 and preventing the side plates 13 from obstructing the handling process of the goods.

[0035] After the goods are lifted, the double-headed hydraulic rod 9 operates, causing the toothed plates 10 on both sides to extend and controlling the rotating shaft 12 to rotate in the opposite direction. This causes the side plate 13 to rotate together with the support plate 15 and come into contact with the goods, causing the spring 14 to be compressed. The restoring force generated by the spring 14 holds the goods against both sides, which can support goods of different widths and also buffer and dampen shocks. This prevents the goods from shaking and hitting the side plate 13 during handling, thus further improving the protection of the goods.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
