Technical Field
[0001] The invention belongs to the field of construction machinery and mining machinery, and particularly relates to an intelligent wall-building machine suitable for mines. Background Art
[0002] Wall masonry is usually built by manual operation, which is labor-intensive, has a bad working environment and poor safety. In recent years, science and technology have been continuously improved, and more and more automatic or semi-automatic masonry equipment has entered the research stage, but the use effect is not satisfactory. Typical cases are as follows: Chongqing Zhongyu Guli Intelligent Technology Co., Ltd. has developed a crawler bricklaying robot that can be used for wall laying operations in the construction industry. The equipment can move and achieve wall laying, but the equipment requires manual work to load bricks one by one, which does not achieve the purpose of reducing labor at all; Guangdong Bozhilin Robot Co., Ltd., a subsidiary of Country Garden Group, has developed a bricklaying robot with a lifting mechanism, which only achieves the displacement of bricks through a three-coordinate structure and relies on manual work to move the equipment, which has no practical value; the SAM100 bricklaying robot developed by the American Construction Robotics company achieves brick laying through the robot, but the equipment is large and cannot be used in confined spaces, such as the construction of filling board walls in underground mine access roads, or the construction of partition walls under the main frame of a built building in civil buildings. Therefore, it can only be used for straight single-wall construction in open environments, and there are very few applicable working conditions and low practical value.
[0003] In summary, although some companies at home and abroad have done research and development of conventional wall-building robots, the equipment has a very simple function and basically only realizes the function of moving bricks. At the same time, the equipment has high use conditions, and most of them remain in the research stage and have not been put into actual use. The few prototypes that have been made also have limitations such as low automation, only able to build straight walls, and high costs. There are no cases of automatic masonry in confined spaces. For wall masonry in confined spaces, such as board wall masonry in mine shafts, or partition wall masonry in civil buildings, there are many difficulties in using mechanized equipment for board wall masonry due to complex environments, harsh conditions, and narrow spaces. At present, no relevant application cases can be found at home and abroad. Summary of the invention

The machine highly integrates a series of functions required for wall construction, including equipment movement, intelligent scanning, automatic positioning, brick supply, mortar supply, brick taking, mortar spreading, brick laying and compaction. The machine is compact, easy to transport and highly intelligent.
[0005] To achieve the above object, the technical solution of the present invention is: An intelligent wall-building machine suitable for mines, the intelligent wall-building machine comprising: The mobile trolley is composed of a frame, a walking and steering mechanism, and a body leveling device.

The frame is used to carry all functional components of the intelligent wall-building machine; the walking and steering mechanism is arranged at the bottom of the frame, including a walking unit and a steering unit, which are used to drive the frame to walk and turn; the body leveling device is arranged around the frame, including a level detection sensor, a swing leg seat, and a telescopic leg, which are used to detect and adjust the level of the body; The scanning and positioning system includes a pan-tilt and a laser radar. The pan-tilt is installed on the frame and has a horizontal rotation function; the laser radar is installed on the pan-tilt and has a vertical line scanning function. Through the horizontal rotation of the pan-tilt and the vertical line scanning of the laser radar, a spatial point cloud model of the external lane contour of the wall to be built is obtained, and the relative position of the equipment and the external contour is located, so as to provide the required raw data for the control system to implement automatic masonry operations; The brick receiving device is composed of a brick support and a positioning device, and is fixedly mounted on the frame; the brick support receives bricks neatly arranged according to a specific rule, and ensures that the position and posture of the bricks are fixed through the positioning device; A feeding device, fixed on the frame, is composed of a feeding hopper, a lifting track, a lifting mechanism, a water adding device and supporting legs, and is used to add water and feed materials into the stirring device; A stirring device, fixed on the frame, consisting of a stirring barrel and a rotating mechanism, used for stirring mortar required for masonry; The mortar supply device is fixed on the frame and consists of a hopper, a pump, a pumping pipeline and a nozzle. The hopper receives the mortar mixed by the stirring device, and the pumping mechanism and the pumping pipeline transport the mixed mortar to the nozzle for applying the mortar to the bricks. A bricklaying device, comprising a robot, a brick fixture and a force sensor connected to the brick fixture; the robot takes bricks one by one from the brick receiving device, applies mortar through the nozzle of the mortar supply device, and places the bricks at the designated position of the wall to be built as planned by the control system; The control system is fixed on the inner side of the frame and is composed of a programmable controller, a touch screen and peripheral devices, and is used to realize the fully automatic control of the intelligent wall-building machine; the brick specifications, wall thickness and the masonry form of each layer of bricks are manually input through the touch screen, and the programmable controller automatically generates a 3D model and a masonry path of the wall to be built according to the original data provided by the scanning and positioning system, and controls the bricklaying device to complete the automatic masonry of the wall to be built.
2. An intelligent wall-building machine suitable for mines as claimed in claim 1, characterized in that: The vehicle body leveling device is composed of a horizontal detection sensor, four swing leg seats and telescopic legs installed on the four swing leg seats; the horizontal detection sensor is a dual-axis inclination sensor, which detects the inclination of the frame in two horizontal directions through the dual-axis inclination sensor, and controls the extension and retraction of the telescopic legs through a programmable controller, thereby ensuring the verticality of the wall-building machine and the ground during the building process, that is, ensuring the verticality of the built wall.
3. The intelligent wall-building machine suitable for mines as claimed in claim 1, characterized in that: The bricklaying device may be one or more. When there are multiple bricklaying devices, the equipment will decompose the actions of taking bricks, applying mortar, placing bricks and compacting. Each bricklaying device completes at least one action, and multiple bricklaying devices complete the action in relay, thereby improving the overall working efficiency of the intelligent wall-building machine.
4. The intelligent wall-building machine suitable for mines as claimed in claim 1, characterized in that: The mobile trolley is also equipped with a lifting platform, which consists of a base, a lifting mechanism and a table top. The base is installed on the frame, a bricklaying device is installed on the table top, and the lifting mechanism is installed between the base and the table top. The lifting mechanism can realize the lifting and lowering of the table top relative to the base, thereby increasing the height range of the bricklaying device.
