Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a material handling device for building construction. Background Technology

[0002] In construction engineering, the handling of bagged materials such as cement requires frequent travel between warehouses, mixing areas, and work sites, making it a high-frequency and demanding task. Existing handling equipment struggles to handle complex terrain and maintain stability in dynamic environments, and there is a lack of intelligent handling devices capable of reliably tracking workers in low-light, dusty, and highly disruptive environments.

[0003] During the handling process, workers need to bend over repeatedly to load and unload cement bags, which is physically demanding and can easily cause back injuries if carried for a long time. The handcarts or flatbed carts used by workers rely on flat ground, and are prone to getting stuck or overturning on unpaved mud or construction sites full of building materials. In addition, large equipment such as forklifts cannot enter narrow construction areas and require professional drivers to operate. Therefore, improvements can be made to address the high risks of manual handling and the poor terrain adaptability of traditional vehicles. Utility Model Content

[0021] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0022] Please see Figures 1 to 5 A material handling device for construction engineering includes a chassis, a robotic arm, and a storage box 1. The chassis includes a working platform 22, a servo motor 21, tracks 2, drive wheels 3, load-bearing wheels 4, and a control board 23. The tracks 2 are connected to the drive wheels 3 and load-bearing wheels 4 by pins to form a wheel set, which can adapt to complex terrain and avoid the inconvenience of traditional vehicles on muddy or uneven ground, thus improving transportation efficiency. The working platform 22 is equipped with ultrasonic sensors 5, the robotic arm, and the storage box 1. The ultrasonic sensors 5 can sense sensors attached to the worker and follow the worker's movement through calculation and analysis by the control board 23. The robotic arm includes a hydraulic power system 8, a control box 15, and an end effector 14, which can transport materials such as cement to the storage box 1, reducing symptoms such as lumbar muscle strain caused by workers repeatedly bending over to carry cement.

[0023] The robotic arm includes a first link 9, a second link 10, a third link 12, a cage 16, a fixed plate 11, a limiting rod 17, a waist motor 20, a rotary motor 18, a rotating shaft 19, a waist upright 7, an end effector 13, and a support platform 24. The base 6 is connected to the waist upright 7, the top of which is connected to the support platform 24. The fixed plate 11 is connected to the third link 12, ensuring the robotic arm's serial structure and facilitating the movement of the end effector 14, providing high flexibility. The first link 9 and the second link 10 are connected by the cage 16 and the fixed plate 11 to maintain parallelism and synchronize their movements. They are also connected to the hydraulic power system 8 to improve the load-bearing capacity of the transported objects and maintain structural stability. The limiting rod 17 is connected to the second link 10, which restricts the movement range of the first link 9 and the second link 10, preventing the robotic arm from losing control.

[0024] The waist motor 20 is connected to the waist support pole 7, and the rotating motor 18 is connected to the rotating shaft 19. Both can control the movement of the robotic arm and adjust its direction. The end hanger 14 is fixedly connected to the end rod 13. If the end hanger 14 is damaged or other tools are needed, it can be disassembled and replaced with different end tools.

[0025] The hydraulic power system 8 is connected to the first connecting rod 9. The support platform 24 is connected to the hydraulic power system 8, the control box 15, the limit rod 17, the first connecting rod 9, and the second connecting rod 10. The first connecting rod 9 and the second connecting rod 10 move synchronously, powered by the hydraulic power system 8, and are suitable for heavy loads.

[0026] The upper end of the work platform 22 is fixedly connected to the ultrasonic sensor 5, the base 6 and the storage box 1, which facilitates ultrasonic detection and material placement by the robotic arm. The lower end of the work platform 22 is fixedly connected to the control board 23. The work platform 22 is made of carbon fiber. The control board 23 controls the ultrasonic sensor 5, the servo motor 21 of the drive wheel 3 and the control box 15. The control board 23 has a built-in battery power supply. The two sides of the work platform 22 are fixedly connected to the servo motor 21 to control the movement of the vehicle.

[0027] The servo motor 21 is connected to the drive wheel 3, and the track 2 is connected to the drive wheel 3 and the load wheel 4, adapting to mud or gravel terrain and automatically following to achieve flexible operation.

[0028] Working Principle: During use, the power to the control board 23 is turned on, energizing the entire device. First, the robotic arm, controlled by the waist motor 20, rotation motor 18, and hydraulic power system 8 (controlled by the control box 15), adjusts the position of the end-effector 14. A worker then uses the end-effector 14 to lift materials. The position of the end-effector 14 is adjusted again so the robotic arm can transport the materials to the storage box 1, improving manual handling efficiency and reducing safety hazards such as slipping and falling in cluttered or slippery areas. Then, the control board 23 activates the ultrasonic sensor 5, the sensor attached to the worker, and the servo motor 21 of the drive wheel 3, enabling the vehicle to automatically follow the worker to the unloading area. Unaffected by light or dust, it is suitable for complex environments such as muddy or gravelly sites, allowing for flexible operation. Upon reaching the unloading area, resetting the robotic arm's movement completes the unloading operation.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
