Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a transport material box lifting mechanism. Background Art

[0002] Most of the transfer boxes used in logistics transportation are automatically transported by AGV vehicles. To lift the transfer boxes, the AGV vehicle needs to be equipped with a lifting structure. The commonly used lifting structure generally uses motors, screws, screw nuts and other structures for lifting. Such a lifting structure has a limited lifting stroke. If the lifting stroke is to be increased, the length of the screw needs to be increased, which leads to an increase in the height of the AGV vehicle. The higher body may be difficult to adapt to low environments or obstacles, and it is easy to be hindered when transporting the transfer boxes, affecting the flexibility of the AGV vehicle. Utility Model Content

[0003] The purpose of the utility model is to provide a transfer box lifting mechanism to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a transfer box lifting mechanism, comprising a base, the left and right sides of the base surface are rotatably connected with electric cylinders and supports, and the electric cylinders and supports on the left and right sides are arranged at the diagonal positions of the base, which can stably support the placement table and improve the stability of the placement table when lifting;

[0005] The surface of the support is rotatably connected with a bending arm, one end of which is rotatably connected to a corresponding electric cylinder. The bending arm can increase the lifting height of the placement table, thereby increasing the lifting height of the material transport box.

[0006] A placing table, wherein two sliding rods are installed on the lower surface of the placing table, and a sliding tube is sleeved on the surface of the sliding rod. The sliding tube is rotatably connected to the other end of the bending arm, and the bending arm can slide flexibly through the sliding tube, ensuring that the electric cylinder can drive the placing table to rise and fall more smoothly;

[0007] The surface of the base is provided with a plurality of support tubes, and the lower surface of the placement table is provided with insertion rods inserted into the support tubes to provide auxiliary support for the placement table and ensure that the placement table does not shake when it is lifted or lowered.

[0008] Furthermore, a universal ball is installed inside the sliding tube, and the universal ball is rotatably connected to the sliding rod. A screw threadedly connected to the universal ball housing is inserted into the surface of the sliding tube. The universal ball reduces the resistance between the sliding tube and the sliding rod, and prevents jamming when the electric cylinder controls the bending arm to rotate.

[0009] Furthermore, a buffer pad is fixedly connected to the surface of the insertion rod, so that when the placement table moves downward, the placement table is prevented from directly colliding with the support tube, thereby reducing vibration.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the bending arm is driven to rotate by the electric cylinder, and when the bending arm rotates, the placement table is driven to move up through the sliding tube and the sliding rod, and when the electric cylinder drives the short end of the bending arm to rotate, the long end of the bending arm rotates with a larger amplitude, which can increase the lifting amplitude of the placement table. When the bending arm is folded up, the space occupied is small, and the height of the AGV vehicle will not be increased too much, ensuring that the AGV vehicle can be used in more complex environments. The AGV vehicle is more flexible and the transportation of transfer boxes is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0017] Example:

[0018] See also Figure 1-4 The utility model provides a technical solution: a transport box lifting mechanism, comprising a base 1, the left and right sides of the surface of the base 1 are rotatably connected with electric cylinders 6 and supports 7, and the electric cylinders 6 and supports 7 on the left and right sides are arranged at the diagonal positions of the base 1;

[0019] A plurality of holes are provided on the edge of the surface of the base 1, so that the base 1 can be mounted on the AGV vehicle by screws 14, and the base 1 can be moved by the AGV vehicle;

[0020] The surface of the support 7 is rotatably connected with a bending arm 8, one end of which is rotatably connected to the corresponding electric cylinder 6. The use of the bending arm 8 facilitates increasing the range of the placement table 4 to rise;

[0021] A placing table 4, wherein two slide bars 10 are installed on the lower surface of the placing table 4, and a slide tube 9 is sleeved on the surface of the slide bar 10, and the slide tube 9 is rotatably connected to the other end of the bending arm 8. The slide tube 9 can reduce the resistance of the bending arm 8 to lift the placing table 4, thereby reducing the load of the electric cylinder 6;

[0022] The surface of the base 1 is provided with a plurality of support tubes 2, and the lower surface of the placement table 4 is provided with an insertion rod 3 inserted into the support tube 2. The support tube 2 and the insertion rod 3 can ensure that the placement table 4 can move up and down, thereby improving the stability of the placement table 4 when it is lifted and lowered.

[0023] In this embodiment, if Figure 1 As shown, an articulated seat 5 is installed on the surface of the base 1, and the articulated seat 5 is rotatably connected to the outer shell of the electric cylinder 6. The electric cylinder 6 is movably supported by the articulated seat 5 to ensure that the electric cylinder 6 can be smoothly extended and retracted, driving the bending arm 8 to rotate.

[0024] In this embodiment, if Figure 1 As shown, a fixed plate 12 is installed at the corner of the bending arm 8, and the fixed plate 12 is rotatably connected to the support 7. The rotational connection between the bending arm 8 and the support 7 is realized through the fixed plate 12, ensuring that the electric cylinder 6 can pull the bending arm 8 to rotate with the support 7 as the fulcrum.

[0025] In this embodiment, if Figure 4 As shown, a universal ball 13 is installed inside the sliding tube 9, and the universal ball 13 is rotatably connected to the sliding rod 10. A screw 14 that is threadedly connected to the outer shell of the universal ball 13 is inserted into the surface of the sliding tube 9. The sliding tube 9 and the universal ball 13 are fixed by the screw 14. The surface of the sliding rod 10 has an arc groove, and the universal ball 13 is rotatably located in the arc groove, which can limit the rotation of the sliding tube 9.

[0026] In this embodiment, if Figure 1 and Figure 2 As shown, a forked seat 11 is connected to the piston rod of the electric cylinder 6, and the forked seat 11 is rotatably connected to the end of the bending arm 8. The forked seat 11 is rotatably connected to the shorter end of the bending arm 8, and the electric cylinder 6 pulls the bending arm 8 to rotate through the forked seat 11.

[0027] In this embodiment, if Figure 1 As shown, a buffer pad 15 is fixedly connected to the surface of the insertion rod 3. When the placement platform 4 moves downward, the buffer pad 15 contacts the support tube 2 to avoid collision and reduce noise.

[0028] Specifically, when in use, the base 1 is installed on the AGV vehicle. When the placement table 4 is in a non-raised state, the bending arm 8 is in a horizontal state, which can reduce the height of the lifting mechanism, thereby controlling the height of the AGV vehicle and the lifting mechanism. When the transfer material box is placed on the placement table 4 and needs to be lifted, the two electric cylinders 6 simultaneously pull the bending arm 8 to rotate, and the other end of the bending arm 8 is raised in a rotating manner. The bending arm 8 drives the sliding tube 9 to slide along the sliding rod 10. At this time, the sliding tube 9 rises with the rotation of the bending arm 8, and the sliding tube 9 lifts the placement table 4 through the sliding rod 10, thereby controlling the rise of the transfer material box.
