Description

Technical Field

[0001] This invention belongs to the field of building inspection technology, and in particular relates to a building exterior wall quality inspection device and its inspection method. Background Technology

[0002] The building exterior wall is the structural component that encloses a building and forms the boundary between the interior and exterior. Its functions include: bearing a certain load, protecting against wind and rain, providing thermal insulation, preventing noise, and ensuring fire safety.

[0003] After the construction of the building's exterior walls is completed, they need to be inspected to determine whether the construction is up to standard. The inspection items mainly include checking whether the wall surface is flat and whether there are hollows inside the wall.

[0004] The flatness of a wall surface is usually measured manually using a balance ruler. This method has a large margin of error. The presence of hollowness inside the wall is usually detected by tapping the wall surface and judging whether it is hollow by the sound. This method is difficult to test any location on the wall. In addition, the above manual measurement methods are inefficient. To solve the above problems, a building exterior wall quality inspection device and its inspection method are provided.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a building exterior wall quality inspection device and its inspection method. By setting control components, it is possible to control the support frame to move in any direction, change the orientation of the support frame so that the hammer faces the wall, and level the base when the ground is inclined, thus avoiding inaccurate inspection caused by ground inclination.

[0007] To achieve the above objectives, the present invention proposes a building exterior wall quality inspection device, the inspection device including a support frame, characterized in that a detection element for inspecting the quality of the exterior wall is slidably mounted on the support frame, and a control element for controlling the movement of the support frame is rotatably mounted on the support frame;

[0008] The support frame includes a base, with an array of casters fixed below the base and a vertical first electric telescopic rod fixed above the base.

[0009] The control component includes a rotating sleeve that rotates on the first electric telescopic rod, a third electric telescopic rod that is vertically fixed to one side of the rotating sleeve, a U-shaped bracket that is fixed to the output shaft of the third electric telescopic rod, and a fourth electric telescopic rod that is rotatably mounted on the U-shaped bracket.

[0010] The control unit also includes a third drive box, in which a third motor is fixed. The output shaft of the third motor passes through the top plate of the third drive box and is fixed to the output shaft of the fourth electric telescopic rod. A horizontal connecting strip is fixed below the third drive box, and at least two insert rods are fixed below the connecting strip. A third distance sensor is fixed on the side of the fourth electric telescopic rod near the rotating sleeve.

[0011] Furthermore, a bushing is fixed above the first electric telescopic rod.

[0012] The detection component includes a horizontal first sliding shaft that slides within a bushing. One end of the first sliding shaft is fixed to a first drive box, and the other end is fixedly connected to a vertical fixing plate. A first motor is fixed inside the first drive box. The detection component also includes two parallel hammers, and a second electric telescopic rod is fixedly connected between the two hammers.

[0013] The output shaft of the first motor passes through the side plate of the first drive box away from the first sliding shaft and is fixed to one of the hammers. A spring is fixedly connected between the fixing plate and the bushing.

[0014] Furthermore, the hammering component includes a first connecting rod parallel to the first sliding shaft, a hammer head fixed to the end of the first connecting rod away from the first sliding shaft, one of the connecting rods fixed to the output shaft of the first motor, a connecting piece fixed above the first connecting rod, a first distance sensor fixed to the side of the connecting piece away from the first motor, and a second electric telescopic rod perpendicular to the first connecting rod.

[0015] Furthermore, a second distance sensor is fixed to the side of the bushing near the fixing plate. The second distance sensor is used to detect the length of the spring.

[0016] Furthermore, a first driving member for driving the detection component to slide is fixed on the support frame.

[0017] Furthermore, the first driving component includes a guide rail fixed above the bushing, the guide rail being parallel to the first sliding shaft, an electrically powered slider being slidably disposed inside the guide rail, a second driving box being fixed above the slider, a second motor being fixed inside the second driving box, and an irregularly shaped plate for driving the fixed plate to move being fixed through the top plate of the second driving box.

[0018] Furthermore, a second driving component for driving the control component to rotate is fixed on the support frame.

[0019] Furthermore, the second driving component includes a gear ring fixedly mounted on the rotating sleeve, an L-shaped bracket fixed above the base, a fourth motor fixed above the top plate of the L-shaped bracket, and a gear meshing with the gear ring fixed through the top plate of the L-shaped bracket.

[0020] A method for inspecting the quality of building exterior walls, applied to the aforementioned inspection device, the method comprising the following steps:

[0021] S1: Adjust the detection position;

[0022] The third electric telescopic rod is oriented toward the desired position by starting the fourth motor to control the rotation of the control component. The length of the third electric telescopic rod is adjusted by starting the third electric telescopic rod. The insertion rod is inserted into the ground by starting the fourth electric telescopic rod. The support frame is moved by starting the third electric telescopic rod. The support frame is turned by starting the third motor so that the hammer head is oriented toward the wall.

[0023] The fourth electric telescopic rod is retracted to control the insertion rod to be pulled out from the ground. When the ground is uneven, the fourth motor is started to control the control component to rotate one revolution. The position of the control component is recorded when the distance detected by the third distance sensor is at its minimum value. Then, the fourth motor is started to adjust the control component to that position. The fourth electric telescopic rod is started to control the insertion rod to be inserted into the ground. When the distance detected by the third distance sensor is the distance between the fourth electric telescopic rod and the rotating sleeve when they are parallel, the base is leveled.

[0024] S2: Check if the wall surface is flat;

[0025] The distance between the connecting piece and the wall is detected by the first distance sensor. The position of the hammer is adjusted by the second electric telescopic rod, the first motor, and the first electric telescopic rod. If the distances detected by the two first distance sensors are the same during the detection process, it indicates that the wall is flat. If the distances detected by the two first distance sensors are different in a certain area, it indicates that the wall is not flat. If the distances detected by the two first distance sensors are always different, the hammer head is not facing the wall. The detection position should be readjusted and the wall flatness should be checked again.

[0026] S3: Check if the inside of the wall is hollow;

[0027] The position of the two hammering parts is adjusted by the second electric telescopic rod, the first motor, and the first electric telescopic rod. The hammering head is controlled by the second motor to hammer the wall. The sound of the hammering is used to determine whether the wall is hollow.

[0028] The building exterior wall quality testing device and method proposed in this invention can bring the following beneficial effects:

[0029] 1. The detection device of the present invention, by setting control components, can control the support frame to move in any direction, and can change the orientation of the support frame so that the hammer is facing the wall. It can also level the base when the ground is inclined, so as to avoid the problem of inaccurate detection caused by the inclination of the ground. Therefore, the detection device can not only realize automated detection and improve detection efficiency, but also measure comprehensively and with small measurement error.

[0030] 2. When the detection device of the present invention encounters a hollow wall during detection, it can determine the extent of the hollowness by activating the first motor and the second electric telescopic rod to adjust the position of one of the hammers and hammer it.

[0031] 3. The detection device of the present invention adjusts the position of the two hammering parts by starting the second electric telescopic rod, the first motor and the first electric telescopic rod working together. The second motor controls the rotation of the irregular plate to hammer the wall. The sound of the hammering is used to determine whether the wall is hollow. The hammering force can be adjusted by starting the slider, so it is suitable for different types of walls. Attached Figure Description
