Description

Technical Field

[0001] The invention relates to a displacement control system and a leveling method for facade decoration, belonging to the technical field of wall decoration brick leveling. Background Art

[0002] Dry hanging of decorative bricks is a new type of construction technology in wall decoration. The stone materials used are usually ceramic tiles or marble wall tiles. This method uses metal hangers to hang decorative bricks directly on the wall or hang them on the wire mesh without grouting and pasting. The principle is to fix the wire mesh on the wall, and fix the decorative bricks on the wire mesh through metal hangers to form a decorative curtain wall.

[0003] The construction process of dry hanging wall decorative tiles: first install several connectors on the wall surface; pre-fix the wire mesh on the wall through the connectors, accurately position and level the wire mesh, then fix the wire mesh on the wall through the connectors, then hang the hangers on the wire mesh, and finally install the decorative tiles in order from bottom to top.

[0004] In the above construction process, since the foundation wall surface is uneven, it is necessary to ensure the flatness of the curtain wall by leveling the wire mesh. In the prior art, each fixed point of the wire mesh is generally leveled manually by a ruler. The leveling workload is too large, and the leveling accuracy is not high enough when the leveling is performed manually by measuring with a ruler.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0006] In view of the deficiencies in the background technology, the present invention provides a displacement control system and a leveling method for facade decoration. A level meter is used to provide a vertical reference plane in the form of a laser. A controller is used to control an actuator to drive the wire mesh to extend and retract, thereby realizing automatic leveling of the wire mesh. The leveling work is efficient and errors caused by human operation are eliminated, thereby achieving higher leveling accuracy.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A control system for a wall decorative brick leveling device, comprising an actuator, and a laser detector, an electromagnet and an infrared rangefinder installed on the actuator; when a fixed point of a wire mesh is leveled, the telescopic rod of the actuator is pressed against the wall position corresponding to the fixed point, the electromagnet attracts the wire mesh, and the infrared rangefinder is used to measure the distance;

[0009] The control system also includes a level meter, which projects a vertical reference plane and illuminates the laser detector, and the vertical reference plane serves as a leveling reference for the wire mesh sheet;

[0010] The utility model also includes a controller, which controls the telescopic rod of the actuator to extend and retract, thereby driving the laser detector to move forward and backward together with the actuator until the reference line of the laser detector coincides with the vertical reference plane of the level.

[0011] Furthermore, when the reference line of the laser detector coincides with the vertical reference plane of the level, the controller calculates the distance L between the wire mesh and the wall, and fixes the fixed point of the wire mesh to the wall using a connector with a size of L.

[0012] Furthermore, the connecting piece is manufactured into different sizes according to the vertical distance between the wall contact surface of the connecting piece and the wire mesh contact surface of the connecting piece.

[0013] Furthermore, the control system also includes an information transmission system, which includes a touch screen and a control button. The infrared rangefinder feeds back the distance measurement value to the controller and displays it on the touch screen in real time. The distance L between the wire mesh and the wall calculated by the controller is also displayed on the touch screen.

[0014] Press the control button to control the telescopic rod of the actuator to extend and retract so that the reference line of the laser detector coincides with the vertical reference plane of the level.

[0015] Furthermore, the control buttons include a "jog +" button, a "jog -" button and an "auto" button. Pressing the "jog +" button and the "jog -" button manually controls the actuator to find the line, and pressing the "auto" button automatically controls the telescopic rod of the actuator to extend and retract.

[0016] Furthermore, a stepper motor is provided inside the actuator, the rotating shaft of the stepper motor is fixed to a screw rod, the screw rod is threadedly matched with the telescopic rod, and the stepper motor drives the screw rod to rotate, thereby driving the telescopic rod to extend and retract.

[0017] Furthermore, the level projects a vertical reference plane parallel to the wall in the form of laser. The laser detector is installed on the side of the actuator. The vertical reference plane is projected onto the laser detector. The laser detector compares its reference line with the vertical reference plane of the level and feeds back the information to the controller. The controller manually or automatically controls the extension and retraction of the telescopic rod of the actuator according to the comparison information, so that the reference line of the laser detector finally coincides with the vertical reference plane of the level.

[0018] A leveling method for facade decoration comprises the following steps:

[0019] S1, pre-fix the wire mesh;

[0020] S2, select a fixed point of the wire mesh, at which the telescopic rod of the actuator presses against the wall and the electromagnet attracts the wire mesh;

[0021] S3, recording the distance L1 between the infrared rangefinder and the wire mesh;

[0022] S4, projecting the vertical reference plane of the level onto the laser detector;

[0023] S5, driving the actuator to make the reference line of the laser detector coincide with the vertical reference plane projected by the level;

[0024] S6, recording the distance L2 between the infrared rangefinder and the wall;

[0025] S7, calculate the distance between the wire mesh and the wall, L=L2-L1;

[0026] S8, use a connector with a size of L to fix the wire mesh to the wall.

[0027] Furthermore, the connecting piece is manufactured into different sizes according to the vertical distance between the wall contact surface of the connecting piece and the wire mesh contact surface of the connecting piece.

[0028] After adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0029] 1. While the actuator moves back and forth, the electromagnet pulls the wire mesh back and forth. When the reference line of the laser detector coincides with the vertical reference plane of the level, the controller calculates the distance L between the wire mesh and the wall, and uses a connector with a size of L to fix the fixed point of the wire mesh to the wall, thereby automatically leveling the fixed point of the wire mesh. The leveling work is efficient and eliminates errors from human operation, making the leveling accuracy higher.

[0030] 2. Use a connector with a size of L to fix the wire mesh to the wall. The size of the connector is divided according to the vertical distance between the wall contact surface of the connector and the wire mesh contact surface of the connector. After leveling the fixed point, use connectors of corresponding size to fix the wire mesh to the wall. There is no need to use connectors with adjustable size, and there is no need to manually adjust the size of the connector. Connectors of corresponding size can be directly used to fix the wire mesh, which is more convenient and improves work efficiency.

[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0041] like Figure 1-3 As shown, the present invention provides a displacement control system for facade decoration, comprising an actuator 2, and a laser detector 6, an electromagnet 8 and an infrared rangefinder 7 installed on the actuator 2; when a certain fixed point of a wire mesh sheet 4 is leveled, the telescopic rod of the actuator 2 supports the position of the wall 1 corresponding to the fixed point, the electromagnet 8 absorbs the wire mesh sheet 4, and the infrared rangefinder 7 is used to measure the distance;

[0042] The control system further comprises a level meter 5, which projects a vertical reference plane and illuminates the laser detector 6, and the vertical reference plane serves as a leveling reference for the wire mesh sheet 4;

[0043] It also includes a controller, which controls the telescopic rod of the actuator 2 to extend and retract, driving the laser detector 6 to move forward and backward together with the actuator 2 until the reference line of the laser detector 6 coincides with the vertical reference plane of the level 5.

[0044] While the actuator 2 moves forward and backward, the electromagnet 8 pulls the wire mesh 4 forward and backward. When the reference line of the laser detector 6 coincides with the vertical reference plane of the level 5, the controller calculates the distance L between the wire mesh 4 and the wall 1. The connector 3 is made into different sizes according to the vertical distance between the wall contact surface of the connector 3 and the wire mesh contact surface of the connector 3. The connector 3 with the size of L is used to fix the fixed point of the wire mesh 4 to the wall 1, so as to realize the automatic leveling of the fixed point of the wire mesh 4. The leveling work is efficient, and the error of human operation is eliminated, so that the leveling accuracy is higher. Then, the other fixed points of the wire mesh 4 are leveled and fixed in turn. After the wire mesh 4 is leveled, the decorative bricks are hung on the wire mesh 4 through metal hangers (not shown in the figure), which can ensure that the decorative wall surface is flat.

[0045] The control system also includes an information transmission system, which includes a touch screen and a control button. The infrared rangefinder 7 feeds back the measured value to the controller and displays it on the touch screen in real time. The distance L between the wire mesh sheet 4 and the wall 1 calculated by the controller is also displayed on the touch screen; pressing the control button controls the telescopic rod of the actuator 2 to retract and extend for line finding (so that the reference line of the laser detector 6 coincides with the vertical reference plane of the level 5).

[0046] The control buttons include a "jog +" button, a "jog -" button and an "auto" button. The actuator 2 can be manually controlled to find the line by pressing the "jog +" button and the "jog -" button, or the actuator 2 can be automatically controlled to find the line by pressing the "auto" button.

[0047] The actuator 2 is provided with a stepper motor inside, the rotating shaft of the stepper motor is fixed to a screw rod, the screw rod is threadedly matched with the telescopic rod, and the stepper motor drives the screw rod to rotate, thereby driving the telescopic rod to extend and retract.

[0048] The level 5 projects a vertical reference plane perpendicular to the ground in the form of laser. The laser detector 6 is installed on the side of the actuator 2. The vertical reference plane is projected on the laser detector 6. The laser detector 6 compares its reference line with the vertical reference plane of the level 5 and feeds back the information to the controller. The controller manually or automatically controls the extension and retraction of the telescopic rod of the actuator 2 according to the comparison information, and finally makes the reference line of the laser detector 6 coincide with the vertical reference plane of the level 5.

[0049] When the electromagnet 8 attracts the wire mesh 4, the infrared rangefinder 7 measures the distance L1 between it and the wire mesh 4, and the infrared rangefinder 7 transmits L1 to the controller for storage. Since the infrared rangefinder 7 is installed on the actuator 2, when leveling different fixed points of the wire mesh 4, the distance between the infrared rangefinder 7 and the wire mesh 4 is constant. Therefore, it is only necessary to measure L1 once when leveling the first fixed point, and directly call L1 for leveling other fixed points; when the reference line of the laser detector 6 coincides with the vertical reference plane of the level 5, the line finding is completed. At this time, the infrared rangefinder 7 measures the distance L2 between it and the wire mesh 4, and the infrared rangefinder 7 transmits L2 to the controller, and the controller performs numerical calculations to obtain the distance L=L2-L1 between the wire mesh 4 and the wall, such as Figure 4 shown.

[0050] The connector 3 has a variety of sizes and specifications. The sizes and specifications of the connector 3 are divided according to the vertical distance between the wall contact surface of the connector 3 and the wire mesh contact surface of the connector 3, such as Figure 5 As shown, after the fixing point is leveled, the wire mesh sheet 4 is fixed to the wall 1 using the connecting piece 3 of corresponding size, and then each other fixing point is leveled in turn.

[0051] The present invention also provides a leveling method for facade decoration, such as Figure 6 As shown, the following steps are included:

[0052] S1, pre-fix the wire mesh 4; fix two or more pre-fixing parts (not shown in the figure) on the wall 1, and hang the wire mesh 4 on the wall 1.

[0053] S2, select a fixed point of the wire mesh 4, at which the telescopic rod of the actuator 2 is against the wall, and the electromagnet 8 absorbs the wire mesh 4; manually support the actuator 2 and push the actuator 2 so that the telescopic rod is against the wall, and at the same time, the controller controls the circuit to energize the electromagnet 8, so that the electromagnet 8 absorbs the wire mesh 4.

[0054] S3, recording the distance L1 between the infrared rangefinder 7 and the wire mesh 4; the infrared rangefinder 7 measures the distance L1 between the infrared rangefinder and the wire mesh, and transmits the value L1 to the controller for storage.

[0055] S4, project the vertical reference plane of the level 5 onto the laser detector 6; the level 5 provides a vertical reference plane for the control system, and the vertical reference plane is perpendicular to the ground. The fixed point of the wire mesh sheet 4 is leveled based on this vertical reference plane.

[0056] S5, drives the actuator 2 to make the reference line of the laser detector 6 coincide with the vertical reference plane projected by the level 5; the laser detector 6 feeds back the position of the vertical reference plane irradiated thereon in the form of laser to the controller in real time, and the controller drives the telescopic rod of the actuator 2 to extend and retract in manual mode or automatic mode, so that the reference line of the laser detector 6 coincides with the vertical reference plane projected by the level 5.

[0057] S6, record the distance L2 between the infrared rangefinder 7 and the wall; when the reference line of the laser detector 6 coincides with the vertical reference plane projected by the level 5, the controller records the distance L2 between the infrared rangefinder 7 and the wall.

[0058] S7, calculate the distance L=L2-L1 between the wire mesh sheet 4 and the wall; the controller calculates the distance L=L2-L1 between the wire mesh sheet 4 and the wall according to the distance L1 between the infrared rangefinder 7 and the wire mesh sheet 4 and the distance L2 between the infrared rangefinder 7 and the wall.

[0059] S8, use a connector 3 with a size L to fix the wire mesh 4 on the wall 1; the connector 3 has a variety of sizes, and the size of the connector 3 is divided according to the vertical distance between the wall contact surface of the connector 3 and the wire mesh contact surface of the connector 3, such as Figure 5 As shown, after leveling the fixed point, the wire mesh 4 is fixed to the wall 1 by the connector 3 of the corresponding size. There is no need to use a connector with adjustable size, and there is no need to manually adjust the size of the connector. The wire mesh 4 can be fixed directly by the connector 3 of the corresponding size, which is more convenient and improves work efficiency.

[0060] According to the above method, the other fixing points of the wire mesh 4 are leveled in turn, and the wire mesh 4 is fixed to the wall 1 with the connecting parts 3 of corresponding size specifications. After the wire mesh 4 is leveled, the decorative bricks are hung on the wire mesh 4 to ensure that the decorative wall surface is flat.

[0061] The specific working principle of the present invention:

[0062] The control system of the leveling device includes a controller, a level meter 5, an actuator 2, and a laser detector 6, an electromagnet 8 and an infrared rangefinder 7 installed on the actuator 2;

[0063] A laser-shaped vertical reference plane perpendicular to the ground is provided by a level meter 5. This vertical reference plane is used as a reference for leveling. The wire mesh 4 is first hung on the wall 1 through a pre-fixed part. The telescopic rod of the actuator 2 is supported against the wall 1 corresponding to the fixed point of the wire mesh 4 to be leveled, and the wire mesh 4 is sucked by the electromagnet 8. The distance L1 between the infrared rangefinder 7 and the wire mesh 4 is measured by the infrared rangefinder 7 installed on the actuator 2, and stored in the controller;

[0064] Then, the controller controls the telescopic rod of the actuator 2 to extend and retract, driving the laser detector 6 installed on the actuator 2 to extend and retract, so that the reference line of the laser detector 6 coincides with the vertical reference plane projected by the level 5 (line-finding process). At this time, the controller records the distance L2 between the infrared rangefinder 7 and the wall, and calculates the distance L=L2-L1 between the wire mesh sheet 4 and the wall.

[0065] Finally, the wire mesh 4 is fixed to the wall 1 using a connector 3 of size L. The connector 3 has a variety of sizes, and the sizes of the connector 3 are divided according to the vertical distance between the wall contact surface of the connector 3 and the wire mesh contact surface of the connector 3.

[0066] According to the above method, the other fixing points of the wire mesh 4 are leveled in turn, and the wire mesh 4 is fixed to the wall 1 with the connecting parts 3 of corresponding size specifications. After the wire mesh 4 is leveled, the decorative bricks are hung on the wire mesh 4 to ensure that the decorative wall surface is flat.
