Description

Technical Field

[0001] The utility model belongs to the technical field of wall surface detection, and in particular relates to a wall surface flatness detection device. Background Art

[0002] Wall flatness is one of the objective indicators for evaluating the quality of wall construction. In order to intuitively evaluate the flatness and changes of the wall, it is necessary to use a wall flatness detection device for measurement and detection to ensure the quality of the building.

[0003] A Chinese patent with publication number CN219390855U discloses a wall flatness detection device, which can adjust the height of the detection component through a lifting component, and can drive the moving component to rotate through a brake motor, so as to adjust the moving direction of the detection component. The detection component can be driven to move through the moving component, so as to detect the wall surface, and the change of the spacing can be accurately detected through an infrared transmitter and an infrared receiver, so that the change of the flatness of the wall can be displayed on a display screen.

[0004] However, in actual use, the moving path of the detection component must be parallel to the reference plane of the wall in order to measure the flatness of the wall by changing the position of the detection component. However, the above scheme cannot select the reference plane according to the wall and make corresponding position adjustments to the detection device, which results in workers setting the position of the detection device based on their feelings and experience, causing the moving path of the detection component to be not parallel to the reference plane of the wall. That is, when the detection component moves along the moving path, the distance of the detection component relative to the reference plane of the wall will change, resulting in incorrect flatness data detected by the detection component, and the flatness of the wall cannot be truly judged. Therefore, the data accuracy of the detection scheme is low. Utility Model Content

[0005] The utility model aims to provide a wall surface flatness detection device to solve the problem of low accuracy of data obtained by the above-mentioned solution.

[0006] In order to achieve the above object, the utility model provides the following technical solutions: a wall flatness detection device, comprising

[0007] A cart, on which a mobile power supply and a control panel are installed;

[0008] The adjustment mechanism includes an electric lifting rod, a horizontal adjustment unit and a reference adjustment unit. The electric lifting rod is installed on the cart. The horizontal adjustment unit is rotatably connected to the electric lifting rod. The reference adjustment unit includes two adjustment members symmetrically arranged on the horizontal adjustment unit. The adjustment members include a nut seat, a limit plate, an adjustment rod and an adjustment cap. The nut seat is installed on the horizontal adjustment unit. The adjustment rod is threadedly matched with the nut seat. The limit plate is fixed to the rod body of the adjustment rod. The adjustment cap is fixed to the end of the adjustment rod. The limit plate and the adjustment cap are both located on the side of the nut seat close to the control panel.

[0009] The detection mechanism is installed on the horizontal adjustment unit.

[0010] The principle and effect of this technical solution:

[0011] 1. The whole device can be moved close to the wall by moving the cart, and the horizontal position and height of the detection mechanism relative to the wall can be adjusted by the electric lifting rod and the horizontal adjustment unit. The reference adjustment unit can position the adjustment mechanism on the reference plane, so that the horizontal movement direction of the detection mechanism is parallel to the reference plane, thereby improving the detection accuracy.

[0012] 2. Since the adjusting rod and the nut seat are threadedly matched, the adjusting rod can be rotated by the adjusting cap to control the position of the adjusting rod relative to the nut seat, so as to control the length of the adjusting rod extending out of the nut seat, and since there are two adjusting members, the two adjusting rods are respectively abutted against the walls on both sides, so that the horizontal adjustment unit can be parallel to the reference plane of the wall, so that the moving surface of the detection mechanism is parallel to the selected reference of the wall, and by rotating the adjusting cap and bringing the detection mechanism close to the wall, the detection mechanism is abutted against the wall, and the flatness of the wall is judged according to the data detected under the reference plane, thereby avoiding the situation that the moving path of the detection mechanism is not parallel to the wall, and improving the detection accuracy.

[0013] The utility model is further configured as follows: a screw is fixed on the top of the electric lifting rod, a connecting plate is slidably inserted on the screw, a nut is abutted on the top of the connecting plate, the nut is threadedly matched with the screw, a horizontal adjustment unit is installed on the side wall of the connecting plate, a frame is installed on the trolley, and both ends of the connecting plate are slidably matched with the frame.

[0014] The principle and effect of this technical solution: through the thread cooperation between the nut and the screw rod, the position of the nut can be adjusted, that is, it can be pressed against the connecting plate to prevent the connecting plate from rotating, and away from the connecting plate, so that the connecting plate can rotate relative to the screw rod, so that the horizontal adjustment unit can be rotated and fixed relative to the electric lifting rod, so that the position of the horizontal adjustment unit can be adjusted according to the wall surface, so that the data obtained by the detection mechanism during detection is more accurate, and the frame can bear the lateral pressure of the connecting plate.

[0015] The utility model is further configured as follows: the horizontal adjustment unit includes a slide rail, a slider, a lead screw and a bidirectional motor, the slide rail is fixed to the side wall of the connecting plate, the slider is slidably fitted in the slide rail, the lead screw is rotatably arranged in the slide rail along the sliding direction of the slider and is threadedly fitted with the slider, one end of the lead screw passes through the side wall of the slide rail and is fixed to the rotating end of the bidirectional motor, the bidirectional motor is fixed on the side wall of the slide rail, the nut seat is installed on the top of the slide rail, and the detection mechanism is installed on the slider.

[0016] The principle and effect of this technical solution: the rotation of the lead screw driven by a bidirectional motor can drive the slider to move relative to the slide rail, so that the slider can drive the detection unit to move horizontally, so that the cart can detect the flatness of multiple positions when it is not moving.

[0017] The utility model is further configured as follows: a guide slide groove is provided on the trolley, an adjusting block is slidably matched in the guide slide groove, and the electric lifting rod and the frame are both fixed on the top of the adjusting block.

[0018] The principle and effect of this technical solution: by setting the guide groove and the adjustment block, the position of the electric lifting rod can be adjusted, thereby adjusting the position of the detection mechanism, the horizontal adjustment unit and the reference adjustment unit, so that the device can be easily stored when not in use, saving the occupation of external space and facilitating transportation and movement.

[0019] The utility model is further configured as follows: the detection mechanism includes an infrared rangefinder, a connecting tube, a roller, a connecting rod, a spring pressure unit and a stroke amplification unit, the connecting tube is fixed to the side wall of the slider, one end of the connecting rod is fixed to the roller, the other end of the connecting rod is slidably inserted into the connecting tube and is connected to the stroke amplification unit, the stroke amplification unit is arranged in the connecting tube, the infrared rangefinder is fixed on the slider and is used to monitor the distance of the stroke amplification unit, and the spring pressure unit is arranged in the connecting tube and is used to drive the connecting rod to reset.

[0020] The principle and effect of this technical solution are as follows: the elastic pressure unit drives the connecting rod to drive the roller to press against the wall, and can automatically adapt to the height of the wall to automatically extend and retract, which is simple and efficient. At the same time, the stroke amplification unit amplifies the extension and retraction amount of the connecting rod relative to the connecting tube, so that the infrared rangefinder can measure more accurate data, improves the detection accuracy of the device, and reduces the error caused by the infrared rangefinder being unable to detect smaller flatness differences due to too small flatness changes.

[0021] The utility model is further configured as follows: the spring-pressing unit includes a pressure plate, a spring and a partition arranged in sequence from left to right, the partition is fixed in the connecting tube, the connecting rod is slidably plugged into the partition, the pressure plate is slidably matched with the inner side of the connecting tube, and the pressure plate is fixed to the connecting rod, the spring is sleeved on the connecting rod and is located between the partition and the pressure plate, and the stroke amplification unit is located on the side of the partition away from the roller.

[0022] The principle and effect of this technical solution: through the setting of the spring, the spring can drive the pressure plate to make the connecting rod drive the roller to always have a pressure against the wall, so that the roller can be fully pressed against the wall and can be pressed automatically. At the same time, when the horizontal adjustment unit drives the roller to move, the roller can automatically extend and retract according to the different levels, saving the steps of manual adjustment and making the operation simple and efficient.

[0023] The utility model is further configured as follows: the stroke amplification unit includes a first rack, a second rack, a gear, a limit rod and a detection block, the gear is installed at the end of the connecting rod away from the roller, the first rack is fixed to the top of the inner side of the connecting cylinder, the second rack slides on the bottom of the inner side of the connecting cylinder, a limit groove is provided at the bottom of the connecting cylinder, the limit rod slides in the limit groove, the top of the limit rod is fixed to the second rack, the bottom of the limit rod is fixed to the detection block, the detection block corresponds to the infrared rangefinder, and the gears are respectively engaged with the first rack and the second rack.

[0024] The principle and effect of the technical solution are as follows: when the roller detects the flatness of the wall, the difference in flatness drives the connecting rod to slide relative to the connecting tube, so that the connecting rod drives the gear to move horizontally, and because the first rack is fixed, the gear can drive the second rack to rotate during horizontal displacement, and can also drive the second rack to move further through the rotation of the gear, so that the stroke of the second rack is doubled relative to the connecting rod, and the sliding limit of the second rack is limited by the limit rod, and the infrared rangefinder detects the detection block, so that more accurate and precise wall flatness data can be obtained, the detection accuracy is improved, and the error caused by the infrared rangefinder being unable to detect the flatness difference due to the flatness change being too small.
