Abstract
Description
Technical Field
[0001] The present invention relates to obstacle clearance and rescue equipment used in natural disasters, and specifically to a miniaturized automatic obstacle clearance and rescue robot. Background Art
[0002] Natural disasters occur frequently in our country, with a wide variety of disaster types, wide distribution, and harsh disaster site environments, as well as many secondary disasters, seriously endangering the lives and safety of the people and rescue workers. Currently, rescue work mainly relies on large construction machinery and equipment, which has problems such as difficult transportation of large construction machinery and low intelligent level.
[0003] By comparing the obstacle clearance and rescue equipment used in natural disasters with the obstacle clearance and rescue equipment used in road traffic, the natural disaster obstacle clearance and rescue equipment is more lightweight and intelligent than the road obstacle clearance and rescue equipment.
[0004] Road obstacle clearance and rescue equipment generally includes a vehicle, a crane, and a lifting mechanism. Refer to the "New Type of Obstacle Clearance and Rescue Vehicle for Responding to Complex Road Environments" published in the first issue of "Labor Protection" in 2019, authors Jiang Huifu and Ren Chunxiao.
[0005] Based on China's geographical environment, centering on improving the efficiency and professionalism of obstacle clearance and rescue operations, strengthening the application of intelligent technology in obstacle clearance and rescue equipment, and promoting the development of natural disaster obstacle clearance and rescue equipment towards modularization, lightweight, and intelligence. Among them, modularization means achieving personalized operation requirements by combining equipment modules; lightweight is achieved by applying new materials and new processes to reach the lightweight goal; intelligence is mainly reflected in aspects such as early warning and intervention during the rescue operation process.
[0006] Currently, most natural disaster obstacle clearance and rescue equipment has a single function. For example, it can only push obstacles away and cannot complete complex handling tasks; the walking mechanism cannot fit well with the ground to complete obstacle crossing; the self-weight of natural disaster obstacle clearance and rescue equipment is too large, and the obstacle clearance ability is limited, etc. It can be seen that improving the obstacle clearance ability and intelligent level of natural disaster obstacle clearance and rescue robots is a realistic demand that needs to be solved urgently. Summary of the Invention
[0007] Aiming at the deficiencies existing in the existing technology of obstacle clearance and rescue equipment used in natural disasters, the purpose of the present invention is to provide a small automatic obstacle clearance and rescue robot that is easy to transport, can transmit real-time on-site images, has a remote control automatic obstacle clearance operation mode, can effectively remove or carry (required pulling force of 1000N) obstacles, can complete all-terrain travel, and has an operation distance of up to 3000 meters.

[0010] The inclined plate mechanism (1) is arranged at the front end of the vehicle body (4) and is used to complete approaching obstacles, moving obstacles, placing obstacles, and unloading obstacles. The inclined plate mechanism (1) includes a left link assembly (1A), a right link assembly (1B), an inclined frame assembly (1C), a rolling transmission assembly (1D), a left inclined plate (1E), a right inclined plate (1F) and a front grounding plate (1G). The link assembly is a four-bar mechanism driven by a link electric push rod; one ends of the upper link and the lower link of the four-bar mechanism are respectively hinged to the upper connecting block and the lower connecting block at the front end of the vehicle body, and the other ends are respectively hinged to the longitudinal beams of the inclined frame; the fixed end of the link electric push rod is hinged to the side plate of the vehicle body, and the telescopic end is hinged to the middle of the lower link. The inclined frame assembly (1C) is composed of two cross beams and four longitudinal beams bolted together.

The front grounding plate (1G) is bolted to the front ends of the left inclined plate (1E) and the right inclined plate (1F).
[0011] The sliding mechanism (7) is arranged at an intermediate position above the vehicle body (4) and is used to drive the right grasping mechanism (2) and the left grasping mechanism (3) to slide back and forth to complete the operation of obstacles. The sliding mechanism (7) includes a linear guide rail module (7A), a slider (7B), a sliding mechanism motor (7C), and a G base plate (7D); the G base plate (7D) is bolted to the front U-shaped support frame (4J4) and the rear U-shaped support frame (4J5); the linear guide rail module (7A) is bolted to the G base plate (7D), and the slider (7B) is bolted to the linear guide rail module (7A).
[0012] The structures of the right grasping mechanism (2) and the left grasping mechanism (3) are the same and they are symmetrically arranged. In order to achieve proper weight balance, the right grasping mechanism (2) is located above the right traveling mechanism (5), and the left grasping mechanism (3) is located above the left traveling mechanism (6). The grasping mechanism is used to grasp or release obstacles. The grasping mechanism includes a grasping arm base, a fixed base, a grasping boom, a grasping boom electric push rod, a grasping forearm, and a grasping forearm electric push rod; the grasping arm base is bolted to the slider (7B); the grasping boom is hinged to the parallel vertical plates of the grasping arm base through a self-lubricating shaft; the fixed end of the grasping electric push rod is hinged to the fixed base, and the telescopic end is hinged to the upper end of the grasping boom; the grasping forearm is hinged to the front end of the grasping boom through a self-lubricating shaft; the fixed end of the grasping forearm electric push rod is hinged to the upper end of the grasping boom, and the telescopic end is hinged to the rear end of the grasping forearm.
[0013] The image acquisition mechanism (8) is used to capture images of the obstacle clearing and rescue environment in natural disasters. The image acquisition mechanism (8) includes a camera support, a camera, a lighting lamp, and lidar around the vehicle body.
[0014] The wireless remote control mechanism (9) is used to achieve wireless communication. The wireless remote control mechanism (9) includes an embedded control module, a high-speed communication radio station, and a video transmission module.
[0015] When the small automatic obstacle clearing and rescue robot designed by the present invention is working, it collects the surrounding environment information of the obstacle clearing and rescue through the camera and lidar, and automatically navigates to the rescue area; rescue personnel can remotely monitor through the video transmitted back by the image acquisition mechanism (8) and perform manual remote control operations when necessary. When clearing obstacles, the electric push rod of the inclined plate mechanism extends, driving the inclined plate mechanism (1) to slowly tilt until the front grounding plate (1G) abuts against the lower inner edge of the obstacle, and at the same time driving the roller (1D2) to start driving the belt (1D1) to rotate; the linear guide rail module (7A) of the sliding mechanism (7) moves the slider (7B) to the front end of the vehicle body; the boom electric push rods of the left and right grasping mechanisms retract, and the forearm electric push rods retract, so that the robotic arm hooks the lower outer edge of the obstacle; the linear guide rail module (7A) moves the slider (7B) to the rear end of the vehicle body, and at the same time the boom push rods (2D6, 3D6) extend, and the forearm push rods (2D4, 3D4) extend, dragging the obstacle onto the vehicle body; finally, the inclined plate mechanism retracts the electric push rods (1A3, 1B3) of the link assembly, driving the inclined plate to move parallel to the front end of the vehicle body, and the robot carries the obstacle away from the obstacle clearing and rescue site.
[0016] The advantages of the small automatic obstacle clearing and rescue robot designed by the present invention are as follows:
[0017] ① The robot of the present invention adopts the combination of a linear guide module and a robotic arm, which can output a pulling force of 1000 N, and can effectively remove or even carry large-weight obstacles in cooperation with the inclined plate structure, having a powerful obstacle-removing ability. On the one hand, traditional obstacle-removing and rescue equipment can only push obstacles away and cannot complete complex carrying tasks. In addition, the robotic arms used on traditional obstacle-removing and rescue equipment are high-degree-of-freedom robotic arms, resulting in poor rigidity of the robotic arms, reducing the load capacity of the robotic arms, and leading to a low obstacle-removing ability of the rescue equipment. Third, compared with the operation distance of 1000 meters of traditional wheeled obstacle-removing and rescue equipment, the robot of the present invention has a first combination formed by the sliding mechanism (7) and the robotic arms (2, 3), and a second combination formed by the tracked walking mechanism (5, 6) and the first combination, with an operation distance of 3000 meters.
[0018] ② For traditional grippers that can be retracted into the storage box, the design of retracting the grippers into the storage box limits the size of the grippers and restricts the obstacle-removing ability of the robot. The robot of the present invention adopts a grasping mechanism arranged symmetrically left and right, having a powerful obstacle-removing ability.
[0019] ③ The tracked walking mechanism adopted by the robot of the present invention has good stability and strong load-bearing capacity, is equipped with a built-in low-speed and high-torque motor walking reducer, has high passability, and can enable the whole machine to achieve convenient movement, turning, climbing, etc., having high mobility. Traditional wheeled obstacle-removing and rescue equipment has poor passability and is limited by the size of the mechanical gripper, and the obstacle-removing ability of this equipment is limited, with a theoretical operation distance of 1000 meters.
[0020] ④ The sliding mechanism in the robot of the present invention can move the robotic arm to the rear end of the vehicle body, and at the same time, the inclined plate mechanism is erected, which can reduce the space occupied by the robot and is convenient for transportation.
[0021] ⑤ The robot of the present invention has a high degree of intelligence. Through a full-angle high-definition camera and lidar around the vehicle body, automatic obstacle avoidance of the robot can be realized. Through the video transmission module, real-time on-site pictures can be transmitted. Through wifi wireless communication, Beidou navigation and positioning, embedded module control, and computer-aided decision-making technology, automatic navigation and automatic obstacle removal of the robot can be realized, and remote operation can also be carried out.
