Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to an expandable cargo handling robot. Background Technology

[0002] Logistics handling robots are intelligent devices that can autonomously complete tasks such as cargo transfer, loading and unloading, and transportation. They are widely used in warehousing, manufacturing, and commercial logistics, with their core functions being to improve handling efficiency and reduce labor costs.

[0003] Patent CN215971306U discloses an expandable cargo handling robot, which includes a handling vehicle. A connecting plate is connected to the side of the handling vehicle, and a rotating rod is installed on the top side of the connecting plate. A clamping mechanism is connected to the top of the rotating rod, and an adjustment component is provided above the clamping mechanism. This device uses the adjustment component to make the electric telescopic rod drive the rack to move, so that the clamping mechanism rotates and adjusts the clamping direction of the two clamping plates, thus solving the problem that adjusting the clamping direction was too cumbersome.

[0004] However, the height of the guardrail in this device is fixed, which means that goods placed on the expansion plate that exceed the highest point of the guardrail are difficult to protect effectively. If a large guardrail is used for protection, it will not only increase the manufacturing cost, but also significantly increase the size of this expansion-type cargo handling robot, thereby reducing its practicality. Therefore, an expansion-type cargo handling robot is proposed to solve the problem that existing handling robots cannot stably protect goods according to the stacking height. Utility Model Content

[0024] Example: Please refer to Figure 1-4An expandable cargo handling robot includes a base plate 1, a driver's cab 2 on the top of the base plate 1, a control arm 3 on one side of the driver's cab 2, a clamping mechanism 4 at the bottom of the control arm 3, a U-shaped expansion plate 5 symmetrically and slidably arranged on the outer ring of the base plate 1, a T-shaped moving groove 6 on the top of the U-shaped expansion plate 5, a T-shaped moving block 7 slidably arranged in the inner cavity of the T-shaped moving groove 6, a guardrail 8 fixedly connected to the top of the T-shaped moving block 7, a second guardrail 9 slidably arranged through the inner cavity of the guardrail 8, an electric telescopic rod 10 fixedly connected to the top of the T-shaped moving block 7, an adjustment mechanism 11 at the bottom of the base plate 1, a limit groove 12 at one end of the U-shaped expansion plate 5, a limit bolt 13 in the inner cavity of the limit groove 12, and casters 14 at the bottom of both the base plate 1 and the U-shaped expansion plate 5.

[0025] Furthermore, the electric telescopic pole 10 passes through the guardrail 8 and is fixedly connected to the second guardrail 9.

[0026] Furthermore, the inner cavity of the limiting groove 12 is interconnected with that of the T-shaped moving groove 6, and the limiting bolt 13 penetrates into the inner wall of the T-shaped moving block 7 and the two are connected by threads.

[0027] Furthermore, the adjustment mechanism 11 includes a fixed plate 111 symmetrically and fixedly connected to the bottom of the base plate 1. The fixed plate 111 is located between two U-shaped expansion plates 5. A bidirectional stud 112 is rotatably arranged between the fixed plates 111. A servo motor 113 is fixedly connected to one side of the fixed plate 111.

[0028] Furthermore, the output shaft of the servo motor 113 passes through the fixed plate 111 and is fixedly connected to the bidirectional stud 112. The outer ring of the bidirectional stud 112 is symmetrical and screwed with two adjusting blocks 114. One side of the U-shaped expansion plate 5 is symmetrically connected with a fixed block 115. A connecting plate 116 is provided between the adjusting block 114 and the fixed block 115. The connecting plate 116 is rotatably connected to both the adjusting block 114 and the fixed block 115. The servo motor 113 on one side of the fixed plate 111 can drive the bidirectional stud 112 to rotate, thereby driving the two adjusting blocks 114 to move to both sides. With the fixed block 115 on the U-shaped expansion plate 5 and the connecting plate 116 rotatably provided between the adjusting block 114 and the fixed block 115, the two U-shaped expansion plates 5 can be driven to move to both ends, thereby expanding the cargo stacking area and facilitating convenient and stable adjustment of the stacking area according to the cargo volume.

Then, the guardrail 8 is moved to the right by the T-shaped moving block 7 in the T-shaped moving groove 6 and the limiting bolt 13 in the limiting groove 12 to avoid obstructing the handling of goods. Then, in conjunction with the cab 2, control arm 3 and clamping mechanism 4, the goods are transported onto the U-shaped expansion plate 5 and the guardrail 8 is reset. According to the stacking height of the goods, the electric telescopic rod 10 drives the second guardrail 9 to move up to the required position to protect the goods, which solves the problem that existing handling robots are difficult to stably protect according to the stacking height of goods. The servo motor 113 on one side of the fixed plate 111 can drive the bidirectional stud 112 to rotate, thereby driving the two adjusting blocks 114 to move to both sides. In conjunction with the fixed block 115 on the U-shaped expansion plate 5 and the connecting plate 116 rotatably set between the adjusting block 114 and the fixed block 115, the two U-shaped expansion plates 5 can be driven to move to both ends, thereby expanding the cargo stacking area and making it convenient and stable to adjust the stacking area according to the cargo volume.
