Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a high adaptability scale device for measuring plane flatness and an operation method thereof. BACKGROUND

[0002] A plane, also known as a horizontal plane, includes a horizontal plane, a vertical plane, an inclined plane, and a component orientation in the form of a plane area. The deviation value of the longitudinal concave-convex amount of the surface of the plane is also referred to as the plane flatness, which mainly reflects the flatness of the longitudinal cross-sectional profile curve of the plane. When the curve is relatively smooth, it indicates that the plane is relatively flat. In building construction, flatness is one of the important indicators of construction quality and service level. It refers to the concave-convex condition of a plane measured discontinuously or continuously with a specified standard gauge, i.e., the indicator of unevenness. The flatness of the plane directly affects the standardization of acceptance and detection indicators such as large component processing, building decoration, and construction. In the measurement process, a measurement device is often needed, and the quality of the measurement device directly affects the detection results. Currently, ordinary measurement devices have certain problems, such as single measurement function, low measurement accuracy, and complicated use. Moreover, an important problem is that they are not convenient to carry, which brings certain inconvenience to users. At the present stage, a straight plate type ruler is generally used to tightly adhere to the plane, and only the concave points that can be visually observed are measured using a plug gauge, which may cause inaccurate selection of measurement points and cannot comprehensively reflect the flatness of the entire straight line.

[0003] The present application compares linear arrangement with a straight plate type ruler, divides into multiple closely arranged points, and each point corresponds to the position of each plane. Arranging multiple points on a straight line plane better covers each position on the entire plane, and the vertical scale components placed on each point realize the amplification and intuitive scale value marking of the high-low difference of the flatness of the detection surface, effectively improving the visibility and visualization of the horizontal difference, and providing tangible, accurate reference conditions and efficient implementation methods for reliable numerical measurement.

[0040] The operation method and implementation principle of a high adaptability scale device for measuring the flatness of a plane comprises the following steps:

[0041] S1: lifting reset

[0042] The T-shaped piece 76 of the first short side lifting guide plate 6 and the second lifting guide plate 7 is pulled out simultaneously using both hands, the through screw 61 is penetrated through the scale assembly 9 and the guard plate connecting piece 83, and the scale assembly 9 and the first long side guard plate 81 and the second long side guard plate 82 are lifted synchronously during the pulling process. The guard plate connecting piece 83 provided at both ends of the long side guard plate is provided with a groove 831 corresponding to the T-shaped guide hole 67 of the short side lifting guide plate, and the through screw 61 is located in the groove 831. The guard plate connecting piece 83 is connected with the long side guard plates on both sides, and the long side guard plates are also displaced synchronously when the through screw 61 is lifted. The first long side guard plate 81 and the second long side guard plate 82 are located in the vertical guide groove 8 provided on the four lifting legs, so that they do not deviate during the lifting process, and the bottom tooth points 915 and the top of each scale tooth 91 in the scale assembly 9 are arranged at the same height.

[0043] S2: moving and falling

[0044] After the first step is completed, the through screw 61 is shifted to the lowest end of the hole shape by pulling the T-shaped hole 911 of the scale tooth 91 and the T-shaped guide hole 67 on the two short side lifting guide plates along the hole shape. The vertical guide groove 8 inside the lifting leg restricts the first long side guard plate 81 and the second long side guard plate 82 from deviating during the movement. The scale assembly 9 is displaced and falls synchronously with the long side guard plate following the through screw 61 while maintaining the order queue and the vertical posture. When the through screw 61 is synchronously dropped to the bottom of the T-shaped guide hole 67 of the vertical center line of the first short side lifting guide plate 6 and the second short side lifting guide plate 7, the scale assembly 9 falling on the measured plane simultaneously presents different high and low states corresponding to the concave and convex parts and the flat parts of the measured plane. The scale tooth 91 falling on the concave point is in a falling state and the scale mark exposes the corresponding value. The scale tooth 91 falling on the convex point is in a protruding state and the scale mark exposes the corresponding value.

[0045] The implementation principle is as follows: first, check or reset the arrangement group of the scale teeth 91 to ensure that it is in balanced contact with the first long side guard plate 81 and the second long side guard plate 82, the T-shaped piece 76 is combined with the through screw rod 61 to form an integral whole and penetrates the first short side lifting guide plate 6, the second short side lifting guide plate 7, the scale assembly 9, and the guard plate connecting piece 83, which is provided with a groove, and the effective movement position of the long screw is limited in the groove space. The T-shaped piece 76 extends outside the first short side lifting guide plate 6 and the second short side lifting guide plate 7. Both hands simultaneously pull the T-shaped piece 76, which is connected to the through screw rod 61, and the through screw rod 61 penetrates the entire scale assembly 9. By lifting the T-shaped piece 76, the scale assembly 9 is lifted upward along the vertical guide groove 8 inside the first lifting stand 2, the third lifting stand 4, the second lifting stand 3, and the fourth lifting stand 5, while the bottom tooth point 915 and the top of each scale tooth 91 in the scale assembly 9 are at the same height. Then, the main body 1 is placed on the detection site, the screw at the foot pad 100 is turned to adjust the height of the four lifting stands, and the bubble level is horizontal. Next, both hands simultaneously move the T-shaped piece 76 to make the through screw rod 61 move from the top inclined recess of the short side lifting guide plate to the downward opening, and then release the hands. At this time, the scale tooth 91 arrangement group is in a sequential queue and an upright posture while falling synchronously with the through screw rod 61 and the left and right long side guard plates due to natural gravity. Finally, the through screw rod 61 falls to the lowest end of the downward opening of the T-shaped guide hole on the first short side lifting guide plate 6 and the second short side lifting guide plate 7, and the tooth point 915 of each scale tooth 91 in the scale assembly 9 contacts the corresponding site and the scale on the scale tooth 91 shows the difference between the current site values. According to this, the flatness data of the plane can be determined. At the same time, the scale main body can be expanded according to actual needs through the long screw hole 101, the long screw recess 102, and the expansion lug cover 105. When large-area flatness measurement is required, measurement data can be obtained at one time, reducing the tedious and repetitive measurement work. The screw through hole 103 and the screw fixing recess 104 are provided with screw threads, and the expansion lug cover 105 outside the screw through hole 103 can realize flexible fixing and use between short side lifting guide plates, scale teeth, and long side connecting rods of different specifications.

[0046] In the embodiment, the scale teeth 91 are the scales for measuring the flatness of a plane or a facade. The scale assembly 9 composed of multiple scale teeth 91 is mainly supported by the through screw 61 and the long side guard plates arranged on both sides of the scale assembly 9. The long side guard plates are used to support the scale assembly 9, and the scale assembly 9 and the long side guard plates are guided to rise and fall by the T-shaped guide holes 67 on the short side lifting guide plates and the vertical guide grooves 8 on the inner side of the lifting legs. The scale teeth 91 on the bottom of the scale assembly 9 are used to contact the plane to be measured, so that the concave-convex parts and the flat parts on the plane can be directly observed. According to the queue type height state and the scale value on the scale teeth 91, the scale assembly 9 can be used to measure the concave-convex parts and the flat parts on the plane with high adaptability and accuracy. In order to facilitate the operation, a rope can be added, and the two ends of the rope are arranged on the T-shaped parts 76 at both ends of the through screw 61, so that the falling point and the lifting reset can be operated by one hand. In order to adapt to the needs of various actual measurement applications, the length of the short side screw strip, the width of the scale teeth and the vertical width of the short side lifting guide plate can be designed in multiple specifications.

[0047] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
