Description

Technical Field

[0001] This invention relates to the field of automation technology in construction machinery, specifically to an intelligent transport robot for reusable materials. Background Technology

[0002] In the construction of super high-rise buildings, the transportation efficiency of reusable materials directly affects the project progress and cost. Currently, the industry generally relies on manual handling combined with traditional equipment such as tower cranes and winches for material transfer. This method has problems such as high manpower consumption, high operational risks, and intermittent waiting. As the building height increases, the frequency of material transfer increases exponentially. Traditional methods can no longer meet the construction efficiency requirements of modern super high-rise buildings. In recent years, the field of construction robots has made breakthroughs in processes such as masonry and spraying, but intelligent transportation equipment for rod-type materials is still lacking.

[0003] Among existing technological solutions, manual handling + hopper transfer: workers collect materials into hoppers and then use tower cranes to lift them to the target floor. The advantage is that it can adapt to irregular material shapes, but the disadvantage is that it relies on manpower and there is a risk of falling from heights. Unloading platform + winch system: materials are piled up on the unloading platform and then lifted by a winch. The advantage is that it has a strong continuous transportation capacity, but the disadvantage is that it requires a fixed installation platform and cannot achieve precise classification and stacking. Tower crane direct lifting: materials are tied with slings and transported vertically. The advantage is that it has high flexibility, but the disadvantage is that it requires frequent use of tower crane resources and has low loading and unloading efficiency.

[0004] Existing technologies still have the following problems: high reliance on human labor leads to rising costs and safety hazards; traditional equipment cannot achieve automatic identification and classification of materials; and there are resource conflicts with other construction equipment during vertical transportation. Therefore, there is an urgent need for a reusable intelligent material transportation robot. Summary of the Invention

[0005] The purpose of this invention is to provide a reusable intelligent material transport robot to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a reusable material intelligent transportation robot, including a walking chassis module, a vertical lifting module installed on the top of the walking chassis module, a material identification module installed at the front end of the top of the walking chassis module, and a robotic arm loading module installed in the middle of the top of the walking chassis module. The walking chassis module includes tracked drive wheels and a steering mechanism. The track width is 200mm, the track pitch is 100mm, and the rated load is ≥500kg. The vertical lifting module includes guide rails and a gear transmission box that match the standard section of the construction elevator. The output shaft tooth profile of the gear transmission box meshes with the gears of the construction elevator. The gear transmission box uses 20CrMnTi alloy steel quenched gears with a module of 4.5 and 28 teeth.

[0007] Preferably, the material identification module uses a 3D vision sensor with a scanning radius covering a range of 5 meters. The 3D vision sensor is Azure Kinect DK based on the ToF principle, with a resolution of 1280×1024, a frame rate of 30fps, and a depth accuracy of ±2mm.

[0008] Preferably, the robotic arm loading module consists of a six-degree-of-freedom articulated arm, an electromagnetic gripper, and a rotating chassis. The electromagnetic gripper has a rated suction force of ≥200kg and is compatible with scaffold tubes with a diameter of 48-60mm. The six-degree-of-freedom articulated arm has a load capacity of ≥100kg and a repeatability of ±0.05mm.

[0009] Preferably, it also includes a control system module, which is electrically connected to the walking chassis module, vertical lifting module, material identification module and robotic arm loading module via a wireless port. The control system module includes a microprocessor and a display panel, integrates a PLC controller, sensor interface and human-machine interface, and uses a Siemens S7-1200 series PLC with an EtherCAT bus interface and supports Modbus TCP / IP communication protocol.

[0010] Preferably, the walking chassis module further includes a track support, which is a self-lifting track support, and the track support is electrically connected to the control system module.

[0011] Preferably, the material identification module also includes multispectral imaging capabilities, adding infrared and ultraviolet imaging technologies in addition to 3D vision.

[0012] Preferably, the robotic arm loading module further includes a torque sensor to monitor the grasping force in real time and to monitor whether an object is grasped each time the gripping is performed.

[0013] Preferably, the material identification module further includes an RFID identification system, with an electronic tag pre-embedded at the end of the material. The RFID identification system is compatible with the electronic tag, and the RFID identification system is electrically connected to the control system module. The RFID system includes an RFID reader / writer, which uses high-frequency reading and writing, operates at a frequency of 915MHz, and has a reading distance of ≥3 meters.

[0014] Preferably, it also includes a safety protection module, which includes a laser obstacle avoidance sensor and an emergency braking system. The laser obstacle avoidance sensor is installed around the steering mechanism, the emergency braking system is integrated into the chassis module, the emergency braking system is electrically connected to the control system module, the laser obstacle avoidance sensor is signal connected to the control system module, and the laser obstacle avoidance sensor is electrically connected to the track support.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: Firstly, in this invention, the material identification module generates three-dimensional coordinates after identifying scattered materials through a vision system. Then, the control system plans the movement trajectory of the robotic arm. After the electromagnetic gripper adsorbs the materials, the device moves to the construction elevator shaft via the walking chassis module. The vertical lifting module's gears mesh with the elevator's standard section, achieving vertical movement via a motor drive. Upon reaching the target floor, the direction is adjusted by rotating the chassis, and the height is adjusted by a six-degree-of-freedom articulated arm, allowing the robotic arm to classify and stack the materials in a designated area according to a preset program. The steering mechanism uses a hydraulic steering system with a steering angle of ±45° and a steering radius ≤1.5m. The walking chassis module has obstacle-crossing capabilities and can move freely on complex ground surfaces via tracked supports. Multispectral imaging is also included. Functions: The system incorporates infrared and ultraviolet imaging technology, with an infrared wavelength range of 8-14μm and an ultraviolet wavelength range of 200-400nm, to identify surface defects and material properties. This information is then uploaded to the control panel. A torque sensor monitors the grasping force in real time with an accuracy of ±1N·m. The sensor detects whether an object is grasped during each gripping attempt. If a gripping attempt fails more than five times, an alarm is sent to the display panel via the control system. This solution saves on the cost of dedicated lifting equipment by reusing the construction elevator drive system. The 3D vision recognition system adapts to the material positioning needs of complex construction sites, reducing reliance on manual labor for transporting reusable materials in high-rise construction and enabling automatic identification and precise classification and stacking of materials such as scaffolding pipes.

[0016] Secondly, this invention utilizes an RFID identification system to enhance the material identification module. Building upon existing 3D vision sensor scanning as base data and multispectral imaging as an auxiliary function, the RFID identification system is the primary tool for classifying and processing each material. Electronic tags are pre-embedded at the ends of the materials, storing material type, specifications, and production date information. The RFID reader employs high-frequency reading and writing at 915MHz, with a reading distance ≥3 meters, and supports the ISO18000-6C protocol. Data transmission: The RFID identification system is electrically connected to the control system module, transmitting material information to the control system module in real time. The location of the scaffolding pipe is determined by a wide-range scan using the 3D vision sensor, and then precisely confirmed by the RFID identification system, further ensuring accurate material classification. The control system module integrates the 3D vision scan data with the RFID tag information to generate a complete material identification report, achieving rapid and accurate material identification, further improving construction efficiency, reducing labor costs, and enhancing the transparency and security of material management.

[0017] Thirdly, in this invention, the safety protection module is installed on the chassis module as a further safety guarantee for equipment movement. Four sets of laser obstacle avoidance sensors are distributed around the steering mechanism, covering 360° omnidirectional obstacle avoidance. The installation height is ≥0.5 meters above the ground to avoid interference from ground obstacles. It uses a SICKLMS511 laser radar with a scanning frequency of 75Hz, an angular resolution of 0.33°, a maximum measurement distance of 80 meters, and a laser wavelength of 905nm, conforming to Class 1 laser safety standards. It communicates with the control system module via a wireless port, transmitting obstacle distance, angle, and speed information in real time. This allows operators to remotely adjust the equipment position manually or automatically based on the obstacle locations provided by the safety protection module, avoiding collisions. The laser obstacle avoidance sensors detect the height of obstacles. When an obstacle is abnormally shaped, the control system module automatically adjusts the height of the track support to avoid collisions. For obstacles that are too high, it directly avoids them. The control system module receives point cloud data and uses the SLAM algorithm to synchronously locate and build a map, updating the environmental map in real time, identifying obstacle types and movement states. When the distance to an obstacle is ≤2 meters, the control system module issues an audible and visual warning through the display panel to remind the operator. When the distance to an obstacle is ≤1 meter, the control system module immediately triggers the emergency braking system, applying maximum braking force to the hydraulic brake. At the same time, the control system module sends a stop command to the robotic arm loading module to prevent the robotic arm from misoperating. This achieves omnidirectional obstacle avoidance, emergency braking, and adaptive adjustment of the track support, enhancing the equipment's adaptability to complex environments and further solving the problem of high reliance on human labor.
