Description

Technical Field

[0001] This invention relates to the field of robotics, and more specifically, to a robot for real-time monitoring of construction sites. Background Technology

[0002] On construction sites, real-time and comprehensive on-site monitoring is crucial for ensuring construction safety, improving project quality and efficiency, and achieving refined management.

[0003] Construction sites require full-time monitoring for various types of work to ensure construction safety and project quality. For example, construction operations involving building facade work and scaffolding erection and dismantling must be carried out on scaffolding. Workers must wear safety ropes, safety nets must completely cover the work surface, and it must be confirmed that there is no risk of materials falling from the scaffolding. Workers must also be checked to ensure they are using fall arresters correctly and taking proper edge protection measures. Fixed cameras are often used for monitoring on construction sites. However, due to the obstruction of scaffolding and changes in working height as construction progresses, the cameras cannot provide real-time and comprehensive monitoring of the construction site, resulting in the inability to provide timely and accurate feedback of relevant information. Summary of the Invention

[0004] The purpose of this invention is to provide a robot for real-time monitoring of construction sites to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides a construction site robot for real-time monitoring, comprising two electric grippers, both of which are clamped onto scaffolding columns. A monitoring mechanism is disposed between the two electric grippers. The two electric grippers are used to fix the monitoring mechanism to the columns so that the monitoring mechanism is close to the construction site. The monitoring mechanism can drive the two electric grippers to move alternately to clamp the columns, so that the two electric grippers can climb along the columns.

[0006] Furthermore, the monitoring mechanism includes: two movable heads connected to the two electric grippers, movable arms connected to the tails of the two movable heads respectively, a main platform, wherein the movable arms are mounted on the main platform, and a pan-tilt camera located on the main platform; The main platform is equipped with a storage battery.

[0007] Furthermore, the movable arm includes: an outer shell mounted on the main body platform, an inner rod slidably inserted into the outer shell, an upper stationary plate mounted at the top of the inner rod, a lower stationary plate mounted at the bottom of the outer shell, and two electric push rods mounted between the upper stationary plate and the lower stationary plate; The directions of the two electric actuators are reversed.

[0008] Furthermore, the main body platform has a support frame, on which a first motor is mounted. A core rod is connected to the output end of the first motor, and the core rod is covered with a sponge strip. When the first motor is started, the core rod can drive the sponge strip to sweep back and forth against the lens of the gimbal camera.

[0009] Furthermore, the main body platform has a suspension platform, the suspension platform is equipped with a water tank, a pipe is inserted into the water tank, the pipe is filled with absorbent cotton strips, and the absorbent cotton strips protrude from the end of the pipe outside the water tank; When the first motor swings the core rod to a horizontal position, the sponge strip contacts the exposed end of the absorbent cotton strip.

[0010] Furthermore, the side of the water tank is connected to a cover groove, and the pipe is inserted into the cover groove; After the sponge strip is fully inserted into the cover groove, it comes into contact with the absorbent cotton strip.

[0011] Furthermore, two baffle plates are rotatably installed on the inner wall of the cover groove, and the two baffle plates extend obliquely upward and centered within the cover groove. Several rubber columns are provided between the back of the two baffle plates and the inner wall of the cover groove. When the sponge strip enters the cover groove, it pushes the two barrier plates apart.

[0012] Furthermore, the movable head includes: a base cylinder, a second motor disposed inside the base cylinder, an end connector rotatably mounted on the base cylinder, and the output end of the second motor is connected to the end connector; The end connector is connected to the electric gripper.

[0013] Furthermore, each of the gripping surfaces of the electric gripper is provided with an arc-shaped rubber pad, and the arc-shaped rubber pad is engraved with a grid pattern.

[0014] Furthermore, the end connector is located near the tail of the electric gripper.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This construction site robot, used for real-time monitoring, uses a pair of electric grippers to firmly fix the monitoring mechanism to the scaffolding columns. The highly flexible monitoring mechanism can directly monitor the construction site from the vicinity of the scaffolding, ensuring it is not obstructed. The two electric grippers alternately clamp the columns during movement, allowing the robot to move along the columns and climb them. This allows for adjustments to the monitoring height as construction progresses or the working height changes. Utilizing the existing scaffolding columns, it provides real-time and comprehensive monitoring of the construction site, promptly feeding back various information. The robot's lens can be cleaned periodically or irregularly using a first motor, core rods, and sponge strips to prevent contamination and ensure clear and unambiguous monitoring images to capture various information from the construction site.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] like Figure 1-8 As shown, a construction site robot for real-time monitoring includes two electric grippers 1, both of which are clamped onto scaffolding columns 2. The columns 2 are a major component of the scaffolding, which also includes horizontal bars, diagonal braces, bases, and fasteners. The columns 2 are the main load-bearing members of the scaffolding, perpendicular to the ground, and responsible for transferring the load of the scaffolding to the foundation. This invention relies on the existing columns 2 on the construction site to monitor the construction site. A monitoring mechanism 3 is provided between the two electric grippers 1, and the two electric grippers 1 are used to fix the monitoring mechanism 3 to the columns 2, so that the monitoring mechanism 3 is close to the construction site. The monitoring mechanism 3 can drive the two electric grippers 1 alternately... The robot moves towards the column 2, allowing the two electric grippers 1 to climb along the column 2. This construction site robot for real-time monitoring uses a pair of electric grippers 1 to firmly fix the monitoring mechanism 3 to the column 2 of the scaffolding. The high degree of freedom of the monitoring mechanism 3 allows it to monitor directly near the construction site, ensuring that it is not obstructed by the scaffolding. The monitoring mechanism 3 can also cause the two electric grippers 1 to alternately clamp the column 2 during movement, thus moving the monitoring mechanism 3 along with the scaffolding and climbing along the column 2. This allows the monitoring height to be adjusted accordingly when the construction process or the working height changes. Relying on the existing scaffolding columns 2, the robot can monitor the construction site in real time and comprehensively, and provide timely feedback on various information.

[0021] Optionally, the monitoring mechanism 3 includes: two movable heads 31 connected to the two electric grippers 1, movable arms 32 connected to the tails of the two movable heads 31 respectively, a main platform 33, with the movable arms 32 mounted on the main platform 33, and a pan-tilt camera 34 located on the main platform 33. When workers are working on the scaffolding, the two electric grippers 1 clamp the corresponding positions on the columns 2, thereby indirectly and firmly fixing the entire monitoring mechanism 3 to the columns 2, allowing the pan-tilt camera 34 to be close to the construction site for monitoring. During construction, the pan-tilt camera 34, with its built-in dual-degree-of-freedom pan-tilt head, can rotate in both horizontal and vertical directions, relying on the existing columns 2 on the construction site to monitor the construction site on the scaffolding, and promptly feeding back various information, completely eliminating the obstruction caused by the scaffolding. The main platform 33 is equipped with a battery, which powers the electric gripper 1, pan-tilt camera 34 and other components that require electric drive, ensuring the normal operation of the robot.

[0022] Optionally, the movable arm 32 includes: an outer shell 321 mounted on the main body platform 33, an inner rod 322 slidably inserted into the outer shell 321, an upper stationary plate 323 mounted at the top of the inner rod 322, a lower stationary plate 324 mounted at the lower part of the outer shell 321, and two electric push rods 325 mounted between the upper stationary plate 323 and the lower stationary plate 324; The two electric actuators 325 are reversed in direction. One electric actuator 325 is mounted on the upper stationary plate 323, with its output shaft connected downwards to the lower stationary plate 324. The other electric actuator 325 is the opposite. It controls the upper electric gripper 1 to release the column 2, and then drives the electric actuator 325 mounted on the lower stationary plate 324 to push the upper stationary plate 323 and the inner rod 322 upwards from the outer casing 321. At the same time, it activates the electric actuator 325 mounted on the upper stationary plate 323, so that it extends its output shaft while maintaining its connection with the lower stationary plate 324, ensuring synchronous movement with the upper stationary plate 323. This moves the upper electric gripper 1 to a new height. Then, it controls the upper electric gripper 1 to re-grip the column 2, forming a fixed point. Then, it controls the lower electric gripper 1 to release the column 2, and then activates the electric actuator 325 mounted on the upper stationary plate 323 to pull the lower stationary plate 324 upwards, causing the outer casing 321 to move upwards. As the inner rod 322 slides upward, it pulls all components, including the main platform 33, upward. Simultaneously, it activates the electric push rod 325 mounted on the lower stationary plate 324, causing it to retract its output shaft while maintaining connection with the upper stationary plate 323. This ensures the outer casing 321 slides upward smoothly. Finally, the electric gripper 1 below grips the column 2, ultimately sending the pan-tilt camera 34 to a new height. The camera then climbs along the column 2, adjusting its monitoring height according to changes in work height during construction, further ensuring real-time and comprehensive monitoring of the construction site and timely feedback of various information. When releasing the two electric grippers 1, they should be opened to their maximum extent to ensure sufficient clearance between them to allow the camera to pass over fasteners and other connection points on the column 2 during linear movement, ensuring smooth upward climbing. During the upward climb, the two electric grippers 1 act as fixing points for the monitoring mechanism 3 on the column 2, ensuring the monitoring mechanism 3 does not fall.

[0023] Optionally, the main platform 33 has a support frame 4, a first motor 5 is installed on the support frame 4, a core rod 6 is connected to the output end of the first motor 5, and a sponge strip 7 is covered on the core rod 6; When the first motor 5 is started, the core rod 6 drives the sponge strip 7 to swing back and forth against the lens of the pan-tilt camera 34. Since there is a lot of dust and other pollutants on the construction site, the first motor 5 can be started periodically or intermittently during construction to continuously swing the core rod 6 and the sponge strip 7 back and forth. This causes the sponge strip 7 to swing back and forth against the lens of the pan-tilt camera 34, sweeping away dust and other pollutants from the lens and cleaning it. This effectively prevents the lens of the pan-tilt camera 34 from being contaminated, thus ensuring that the clarity of the monitored image is affected and that all information from the construction site is fed back through a clear and concise monitoring screen.

[0024] Optionally, the main body platform 33 has a suspension platform 8, the suspension platform 8 is provided with a water tank 9, a pipe 10 is inserted into the water tank 9, the pipe 10 is filled with absorbent cotton strips 11, and the absorbent cotton strips 11 protrude from the end of the pipe 10 outside the water tank 9. When the first motor 5 swings the core rod 6 to a horizontal position, the sponge strip 7 contacts the exposed end of the absorbent cotton strip 11. After each cleaning of the lens of the gimbal camera 34, the first motor 5 swings the core rod 6 to a horizontal position and holds it there. At this time, the absorbent cotton strip 11 contacts the sponge strip 7, and the water on the absorbent cotton strip 11 has a target. Under capillary action, the water in the water tank 9 is continuously and slowly transferred to the sponge strip 7 through the absorbent cotton strip 11, thereby wetting the sponge strip 7. In this way, the wet sponge strip 7 can be used to wipe the lens of the gimbal camera 34. When there are stains or other contaminants on the lens of the gimbal camera 34, they can be wiped away more effectively, resulting in a better cleaning effect.

[0025] Optionally, the side of the water tank 9 is connected to a cover groove 12, and the pipe 10 is inserted into the cover groove 12; After the sponge strip 7 is fully inserted into the cover groove 12, it comes into contact with the absorbent cotton strip 11. That is, when the sponge strip 7 is not in use, it can be concealed in the cover groove 12 and receive moisture from the water tank 9, thereby providing a certain degree of protection for the sponge strip 7 and preventing it from being completely exposed to the construction site environment. This achieves self-maintenance and prevents a large amount of dust and other pollutants from falling on the sponge strip 7 as a cleaning tool and contaminating it, which would greatly reduce the effectiveness of wiping the lens.

[0026] Optionally, two baffle plates 13 are rotatably mounted on the inner sidewall of the cover groove 12, and the two baffle plates 13 extend obliquely upward and centered in the cover groove 12. A plurality of rubber columns 14 are provided between the back of the two baffle plates 13 and the inner sidewall of the cover groove 12. When the sponge strip 7 enters the cover groove 12, it pushes the two barrier plates 13 apart. When the sponge strip 7 enters the cover groove 12, the two barrier plates 13 are centered and obliquely close together, forming a barrier on the movement path of the sponge strip 7. With the continuous drive of the first motor 5, the core rod 6 and the sponge strip 7 compress several rubber columns 14, causing the two barrier plates 13 to rotate to both sides until the sponge strip 7 is completely squeezed into the cover groove 12. During this process, the two barrier plates 13 also squeeze the sponge strip 7, thereby squeezing off the dirty water on the sponge strip 7 that has just been wiped of dust and other contaminants, keeping the sponge strip 7 as clean as possible, and thus obtaining a good cleaning effect. The self-cleaning maintains the long-lasting cleaning effect and avoids the need for frequent manual cleaning of the sponge strip 7. After the core rod 6 and the sponge strip 7 leave, the several rubber columns 14 rebound and return to their original shape, pressing the two barrier plates 13 back to their original positions.

[0027] Optionally, the movable head 31 includes: a base cylinder 311, a second motor 312 disposed inside the base cylinder 311, and an end connector 313 rotatably mounted on the base cylinder 311, wherein the output end of the second motor 312 is connected to the end connector 313. The end connector 313 is connected to the electric gripper 1. Activating the second motor 312 can rotate the end connector 313, thereby causing the angle of the electric gripper 1 to also rotate, causing it to deviate relative to the column 2. When encountering fasteners or other connection points on the column 2 during the upward climbing process, it can avoid them, further ensuring that the two electric grippers 1 can smoothly cross fasteners and other connection points when moving in a straight line, thus achieving the purpose of changing the monitoring height.

[0028] Optionally, each of the clamping surfaces of the electric gripper 1 is provided with an arc-shaped rubber pad 15, and the arc-shaped rubber pad 15 is engraved with a grid pattern. On the one hand, the rubber can increase the friction, and on the other hand, the soft arc-shaped rubber pad 15 can adapt to the contour of the column 2 when the electric gripper 1 clamps the column 2, ensuring that the electric gripper 1 can also clamp the column 2 tightly even when there are solid objects such as concrete on the column 2, thereby ensuring sufficient fixing force to firmly fix the monitoring mechanism 3 and other components, and ensuring that they will not fall off due to the movement during construction.

[0029] Optionally, the end connector 313 is located near the tail of the electric gripper 1. That is, the end connector 313 and the main platform 33 and other components are relatively far away from the column 2, while only the gripper of the electric gripper 1 is relatively closer to the column 2, which fundamentally prevents any components from obstructing the scaffold during the climbing process.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
