Description

Technical Field

[0001] The invention relates to the technical field of steel structure building engineering, and in particular to a high-altitude spraying device for steel structure buildings and a use method thereof. Background Art

[0002] Steel structure buildings are stronger than traditional brick-concrete structures. At the same time, steel structure buildings usually adopt modular splicing technology, so the construction speed is usually faster. However, steel is easily corroded when exposed to air and rain for a long time. To avoid this phenomenon, paint is usually sprayed on the surface of steel structure buildings to prevent corrosion and rust. The painting of steel structure buildings is generally done manually. The most common method is to use ropes to lower construction workers or hanging baskets to the painting site for construction. Manual painting wastes a lot of paint, has low spraying efficiency, and the thickness of the sprayed coating is uneven, which can cause defects such as peeling, flaking, and bubbles. At the same time, construction workers have to face VOC directly when spraying paint, and frequently go up and down to replace paint buckets, which poses a great safety hazard.

[0003] After searching, the invention with publication number CN113019776B provides a surface paint coating spraying device for high-rise steel structures, which relates to the technical field of paint spraying equipment; in order to solve the problem that the surface of high-rise steel structures cannot be effectively sprayed; this device specifically includes a paint storage box, and two mounting plates are respectively provided on the outer walls of one side of the paint storage box, and two mounting columns are respectively fixed to the outer walls of one side of the two mounting plates by screws, and a control panel and a liquid inlet valve are respectively provided on the outer walls of one side of the paint storage box, and a second groove is opened on the outer wall of one side of the paint storage box; although this invention solves the problems of low efficiency and lack of safety caused by manual spraying, the invention needs to rely on tracks to move during the movement process. In a high-altitude working environment, the track is difficult to install, resulting in the invention being unable to perform spraying operations in a high-altitude environment, and cannot be a good substitute for manual painting in a high-altitude environment. Summary of the invention

[0004] In order to solve the problem that traditional spraying devices are limited in mobility and cannot replace manual spraying well in high-altitude working environments, as well as the problem that traditional manual high-altitude spraying operations are low in efficiency and lack of safety guarantees, the present invention proposes a high-altitude spraying device for steel structure buildings and a method of use to solve the above problems.

[0005] A high-altitude spraying device for steel structure buildings comprises a control center base, a first base and a second base, a control terminal is installed inside the center base, a spraying component is installed on the side of the center base away from the working surface, a cavity is opened inside the center base, a first telescopic rod is matched in the cavity, the first telescopic rod movably connects the center base and the first base, the first telescopic rod movably connects the center base and the second base, a groove is opened on the side of the center base, the first base and the second base close to the working surface, a support plate is arranged inside the groove, an electromagnet is installed on the side of the support plate close to the working surface, one end of a spring is connected to the other side of the support plate, the other end of the spring is connected to the inner surface of the groove away from the working surface, a thread is arranged on the inner surface of the cavity, a motor A is installed on the end of the first telescopic rod extending into the cavity, the motor A is matched with a screw rod, the motor A is electrically connected to the control terminal, and the screw The rod is threadedly matched with the inner surface of the cavity, and a limit block is arranged at the opening of the cavity; the device is fixed on the working surface by the on and off of the electromagnet, and no additional rails or supports are required for support, which improves the applicability of the device. The alternating on and off of the electromagnet and the cooperation of the telescopic rod enable the device to move independently on the surface of the steel structure without the need for repeated arrangement, thereby improving work efficiency. Furthermore, the staff does not need to perform high-altitude operations, and the staff can control and monitor the device in a safe position, avoiding the safety hazards and quality problems existing in the traditional high-altitude steel structure painting construction process. When the electromagnet is energized for adsorption, the mounting plate moves toward the working surface, the spring is stretched, and the mounting plate is blocked by the limit block, which prevents the electromagnet from completely coming out and causing the spring connection to break and the fixation to fail. When the electromagnet is powered off, the spring rebounds to pull the electromagnet back to the initial position to avoid direct friction with the working surface during movement and cause wear.

[0006] Furthermore, when the robotic arm rotates, when it rotates to the farthest end, the center of gravity of the device moves away from the working surface. Under the action of gravity, the entire device will tilt away from the working surface. When tilting, the mounting plate at the bottom of the base moves in the groove, and when it moves to the opening of the groove, it is blocked by the limit block to prevent the mounting plate from falling out, limit the tilt of the device, and prevent the device from tilting excessively. At the same time, the control terminal sends a signal to remind the construction personnel to use a safety rope to help stabilize the device. If the signal is not responded, the device will automatically control the robotic arm to retract to the initial state and increase the magnetic force of the electromagnet to strengthen the stability and enter the protection state to avoid falling objects from high altitude.

[0007] Furthermore, the support plate moves inside the groove, a limit block is provided at the opening of the groove, an electromagnet controller is installed inside the support plate, and the electromagnet controller is electrically connected to the control terminal; the control terminal can receive control signals from construction personnel and transmit working data to the controller at the same time, so as to help the staff judge the working condition of the device and improve work efficiency.

[0008] Furthermore, the spraying component is a robotic arm, which is bolted to the center base, a robotic arm base is provided at the connection between the robotic arm and the center base, the robotic arm base is rotatable, the robotic arm base is fixedly connected to one end of the robotic arm, a spray gun is installed at the other end of the robotic arm, and the spray gun rotates around the robotic arm; the selection of the spraying component is selected according to the specific construction environment. The present invention selects to use a robotic arm as the spraying component, the robotic arm can rotate around the base, and the spray gun can rotate around the robotic arm, which greatly expands the range of spraying, and can also adapt well to the spraying of irregular parts, greatly improving the work efficiency.

[0009] Furthermore, rollers are installed on the outer surfaces of the central base, the first base and the second base close to the working surface; when the electromagnet stops adsorption and moves, the use of rollers can effectively reduce friction, avoid direct friction between the electromagnet and the working surface, and reduce wear.

[0010] Furthermore, the first telescopic rods include a plurality of first telescopic rods, two of which form a group, and the first telescopic rods are symmetrically arranged along the working direction; the symmetrical arrangement can evenly distribute the pulling force, which helps to help the base move during the movement process and improve the movement efficiency.

[0011] Furthermore, a connecting seat is provided at the connection between the first telescopic rod and the first base, a fixing ring is provided at the end of the connecting seat away from the working surface, a connecting seat is provided at the connection between the first telescopic rod and the second base, a fixing ring is provided at the end of the connecting seat away from the working surface, and the fixing ring is cooperated with a safety rope; multiple fixing rings are provided to cooperate with the safety rope to strengthen safety measures, and the posture of the device can also be controlled by the safety rope to fit the working surface so that the device can operate better.

[0012] Furthermore, the device is powered by an external cable, which includes a power line and a signal line, and the signal line is electrically connected to the controller; using external power supply reduces the weight of the device and extends the working time of the device. At the same time, the paint is delivered to the spray gun through a delivery pipe, and the device itself does not carry paint, avoiding the need for repeated replenishment of paint and improving work efficiency.

[0013] A method for using a high-altitude spraying device for a steel structure building comprises the following steps:

[0014] S1. Test the working surface: Before using the device, it is necessary to pre-test the construction site, use the center base, install a safety rope on the fixed ring on the surface of the center base, install a test weight on the surface of the center base, and the weight of the test weight is 1.5-2 times the weight of the entire device. Connect the weight firmly, move the center base to the working surface, turn on the power to start the electromagnet at the bottom of the center base, and test whether the electromagnet can be normally adsorbed to the working surface, and keep it for a period of time to observe whether the center base has a tendency to detach.

At the same time, the first telescopic rod (3) connecting the central base (1) and the first base (4) is started, and the motor A (301) is started to drive the screw rod (302) to rotate along the inner surface thread of the cavity (303), thereby pulling the central base (1) to move toward the first base (4); S6, moving the first base (4): after the central base (1) is moved into position, the electromagnet (8) at the bottom of the central base (1) is energized to start adsorption, the electromagnet (8) at the bottom of the first base (4) is de-energized, and at the same time, the first telescopic rod (3) connecting the central base (1) and the first base (4) is started, the motor A (301) is started to drive the screw rod (302) to rotate in the opposite direction, so that the first telescopic rod (3) moves in a direction away from the central base (1), pushing the first base (4) to move in a direction away from the central base (1), and after moving into position, the electromagnet (8) is energized to start adsorption, and the movement is completed; S7, restarting work: the robot arm (2) starts the spraying operation, and after completion, repeats S4-S7 to move and spray construction until the entire spraying operation is completed.
