[0002] In the building construction process, the cement plastering process of the wall surface is always an extremely important process, and the traditional plastering process is basically manually operated by workers using professional tools. However, the high standard construction specification requires the construction personnel to have high technical level, and due to the huge workload and high labor intensity, the construction efficiency is generally low, and the construction quality cannot be guaranteed due to subjective factors such as experience and state of the construction personnel.

[0003] Various auxiliary construction equipment has appeared on the market today, but most of them are semi-automatic plastering equipment, and the movement, positioning, and posture correction of each device still need to be operated manually. Due to the factors such as the overburden of the equipment and the complexity of the operation, two to three people are needed to assist in the construction operation of each device, and the excessive manual intervention easily leads to uneven construction quality, which seriously reduces the construction speed and economic benefits.

[0016] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0017] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

[0018] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0020] Example A plastering device, such as Figure 1 As shown, the device includes a walking mechanism 1000, a lifting mechanism 2000, and a control mechanism 3000. The walking mechanism 1000 is used to move the plastering device. One end of the lifting mechanism 2000 is rotatably mounted on the top of the walking mechanism 1000, and the lifting mechanism 2000 can rotate slightly horizontally relative to the walking mechanism 1000. The other end of the lifting mechanism 2000 is equipped with a rotatable plastering mechanism 4000, and a portion of the plastering mechanism 4000 can rotate slightly vertically relative to the lifting mechanism 2000. The control mechanism 3000 is used to sense the posture of the plastering mechanism 4000 and adjust the posture of the plastering mechanism 4000 to a preset posture.

[0021] In this embodiment, the lifting mechanism 2000 is rotatably connected to the traveling mechanism 1000 via the slewing mechanism 5000.

[0022] In this embodiment, the plastering mechanism 4000 includes a support frame 4100, a trowel 4200, and a driving mechanism. The support frame 4100 is disposed at the other end of the lifting mechanism 2000 via a push rod and a guide rail, and one end of the support frame 4100 is connected to the lifting mechanism 2000. The trowel 4200 is rotatably connected to the other end of the support frame 4100. The fixed end of the driving mechanism is fixedly connected to the support frame 4100, and its output end is rotatably connected to the trowel 4200. The extension and retraction of the output end drives the trowel 4200 to rotate.

[0023] In this embodiment, the top of the trowel 4200 is provided with a mortar receiving tray 4300 to catch concrete that falls during the troweling process and prevent it from falling to the ground or the support frame 4100.

[0024] The control mechanism 3000 includes a vision camera, a tilt sensor, and a programmable logic controller. The vision camera is mounted on the lifting mechanism 2000 and can be adjusted vertically to sense the horizontal tilt angle of the trowel 4200. The tilt sensor is mounted on the plastering structure to sense the vertical tilt angle of the trowel 4200. The programmable logic controller is used to adjust the trowel 4200 based on the sensed tilt angle data.

[0025] The programmable logic controller can preset the inclination angle of the trowel 4200.

[0026] In use, the troweling device can compare the preset laser line viewed by the visual camera with the preset trowel 4200 simulation line preset by the programmable logic controller, and if there is a deviation, the deflection angle is read, the programmable logic controller controls the rotation mechanism 5000 to rotate, and drives the trowel 4200 to rotate to the preset inclination angle (one side of the inclination angle is 0°, that is, parallel to the wall surface in the horizontal direction) in the horizontal direction. After the horizontal direction inclination angle adjustment is completed, the inclination angle of the trowel 4200 in the vertical direction is recognized by the inclination angle sensor and compared with the preset inclination angle, and if there is a deviation, the deflection angle is read, the programmable logic controller controls the driving mechanism to extend and retract, and drives the trowel 4200 to reach the preset angle (generally set to be perpendicular to the ground) in the vertical direction, thereby realizing the troweling correction work on the wall body in the axial direction and the perpendicularity.

[0027] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0028] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
