[0030] The following describes the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
[0031] As Figure 1-Figure 2 shown, a cargo handling lifting mechanism includes:
[0032] A movable base 1, through which the movement of the lifting mechanism can be achieved.
[0033] A scissor-type hydraulic lifting mechanism 2, which is installed on the movable base 1. The scissor-type hydraulic lifting mechanism 2 includes a hydraulic telescopic rod 21, scissor arms 22, and a lifting plate 23. An angle adjustment mechanism 3 is provided between the lifting plate 23 and the scissor arms 22, and the angle adjustment mechanism 3 is used to adjust the angle of the lifting plate 23.
[0034] A positioning mechanism 4, which is provided on the lifting plate 23 and positions the cargo placed on the lifting plate 23.
[0035] By extending or contracting the hydraulic telescopic rod 21 to drive the movement of the scissor arms 22, and the scissor arms 22 drive the lifting plate 23 to move up and down, the lifting function of the lifting plate 23 can be realized. By providing an angle adjustment mechanism 3 between the lifting plate 23 and the scissor arms 22, according to the placement requirements of the cargo, the angle adjustment mechanism 3 can adjust the angle of the lifting plate 23, which is convenient for placing the cargo on the lifting plate 23. At the same time, by providing a positioning mechanism 4 on the lifting plate 23, the cargo can be positioned to prevent the cargo from shifting.
[0036] As Figure 1-Figure 2 shown, in some embodiments, the angle adjustment mechanism 3 includes a telescopic cylinder 31 and a connecting plate 32. The first end of the telescopic cylinder 31 is connected to the scissor arm 22, the second end of the telescopic cylinder 31 is hinged to the connecting plate 32, and the connecting plate 32 is connected to the lifting plate 23. The telescopic cylinder 31 drives the movement of the connecting plate 32 through expansion and contraction, and the connecting plate 32 drives the lifting plate 23 to move together, so as to realize the adjustment of the angle of the lifting plate 23, making the lifting plate 23 change from a horizontal state to an inclined state, or from an inclined state to a horizontal state, thus facilitating the placement of the cargo.
[0037] It should be noted that the cross-section of the connecting plate 32 is in the shape of a "冂", and the second end of the telescopic cylinder 31 is hinged to the inner side walls of the connecting plate 32 through a hinge.
[0038] like Figure 1-Figure 2 As shown, in some embodiments, the telescopic cylinder 31 includes a bidirectional telescopic cylinder 31. The angle of the lifting plate 23 is adjusted by using the bidirectional telescopic cylinder 31. The stroke of the bidirectional telescopic cylinder 31 is relatively long, which can ensure the angle adjustment range of the lifting plate 23, and can withstand a larger load and perform telescopic movements smoothly.
[0039] like Figure 1-Figure 2 As shown, in some embodiments, the positioning mechanism 4 includes a mounting plate 41, a positioning cover 42, a plurality of positioning posts 43 and a plurality of elastic members, the mounting plate 41 is arranged on the top of the lifting plate 23, the positioning cover 42 is fixedly connected to the mounting plate 41, a plurality of the positioning posts 43 pass through the top of the positioning cover 42, the positioning posts 43 and the positioning cover 42 are in sliding contact, and a plurality of the positioning posts 43 and the mounting plate 41 are connected through elastic members, when the goods are placed, the goods press the positioning posts 43 at the bottom thereof to move toward the mounting plate 41, when the goods are placed, the top of the goods contacts the positioning posts 43, the goods press the positioning posts 43 below thereof to move toward the mounting plate 41, the elastic members are compressed, and the positioning posts 43 not at the bottom of the goods will not be subjected to pressure, and in the initial state, the positioning posts 43 not in contact with the goods fit the contour of the goods, thereby ensuring the positioning effect of the goods and preventing the goods from moving.
[0040] Furthermore, the elastic member includes a spring. By using the spring as the elastic member, when the positioning column 43 corresponding to the spring is subjected to pressure, the positioning column 43 presses the spring to move toward the mounting plate 41, and the spring is compressed. When the goods are taken away, the positioning column 43 returns to its initial position under the action of the spring restoring force.
[0041] In other embodiments, the elastic member may also be made of other elastic materials, such as elastic rubber, which can be selected according to actual conditions.
[0042] like Figure 1-Figure 3 As shown, in some embodiments, a rotating mechanism is further provided between the positioning mechanism 4 and the lifting plate 23, so that the positioning mechanism 4 can rotate relative to the lifting plate 23. By providing a rotating mechanism between the positioning mechanism 4 and the lifting plate 23, the positioning mechanism 4 can rotate relative to the lifting plate 23, which facilitates the storage and retrieval of goods.
[0043] like Figure 1-Figure 3As shown, in some embodiments, the rotating mechanism includes a plurality of balls 9 and a rotating shaft 10, the rotating shaft 10 passes through the lifting plate 23 and is connected to the positioning mechanism 4, a plurality of the balls 9 are arranged at the bottom of the positioning mechanism 4, and an annular groove 11 is opened at the top of the lifting plate 23, the balls 9 are at least partially accommodated in the annular groove 11, and when the positioning mechanism 4 rotates, the balls 9 move in the annular groove 11.
[0044] like Figure 1-Figure 3 As shown, in some embodiments, a through groove 5 is provided on the movable base 1, the first end of the hydraulic telescopic rod 21 is hinged to the scissor arm 22, and the second end of the hydraulic telescopic rod 21 passes through the through groove 5 and is hinged to the bottom of the movable base 1. By providing the through groove 5 on the movable base 1, the hydraulic telescopic rod 21 passes through the through groove 5, so that part of the hydraulic telescopic rod 21 can be located below the movable base 1, which is convenient for the installation of the hydraulic telescopic rod 21 and ensures the range of motion of the hydraulic telescopic rod 21.
[0045] like Figure 1-Figure 3 As shown, in some embodiments, the lifting mechanism further includes a manually controlled cylinder 6, and the manually controlled cylinder 6 is connected to the scissor arm 22. By setting the manually controlled cylinder 6, the raw rubber operation of the lifting plate 23 can be manually controlled.
[0046] like Figure 1-Figure 3 As shown, in some embodiments, a plurality of universal wheels 8 are installed at the bottom of the movable base 1. By installing the universal wheels 8 at the bottom of the movable base 1, the movable base 1 is convenient to move. A self-locking mechanism is provided on the plurality of universal wheels 8. The self-locking mechanism is provided on the universal wheels 8, and the self-locking function of the universal wheels 8 can be realized;
[0047] The movable base 1 is provided with a push handle 7, and the push handle 7 is provided to facilitate the staff to push the movable base 1 to move.
