Description

Technical Field

[0001] The invention relates to the technical field of building detection, and in particular to a wall verticality detection device. Background Art

[0002] Wall verticality detection is a measuring tool used in construction projects to ensure that the wall is perpendicular to the ground. This detection is very important for ensuring the stability and aesthetics of the building structure. The existing verticality detection of whether the wall is vertical is usually done by manually holding a simple vertical board against the wall and then visually observing the gap between the wall and the vertical board to determine whether the wall is vertical.

[0003] However, at the location where the radiator is installed, a groove is usually opened on the wall to accommodate the radiator. The height and depth of the groove are adapted to the radiator, with a height of 80-100cm and a depth of 15-20cm. When it is necessary to check the verticality of the inner wall of the groove, the staff needs to bend over and then check the verticality of the wall.

[0004] In the process of wall verticality detection, the detection of a single point cannot be used as the detection standard for the verticality of the front wall. Therefore, the staff is required to conduct multiple detections of the verticality of the wall at different heights and positions. The long-term bending over detection brings a heavy labor burden to the staff. In addition, there is a certain error in judging the verticality of the wall by the naked eye, resulting in low accuracy of the detection results. Summary of the invention

[0017] 1. When testing the verticality of the wall, move the base to the side of the wall to be tested, drive the base to move toward the wall, and after the abutment block abuts against the wall, the abutment block tilts with the inclination angle of the wall, and then transmits it to the gear through the installation shaft, and the gear transmits it to the indicator rod through the rack. The pointer on the indicator rod indicates the specific value on the scale, and the inclination angle of the wall can be quickly tested. The operation is simple and convenient, which effectively reduces the labor intensity of the staff;

[0018] 2. When detecting the angle of the wall, the inclination angle of the wall is often small. The inclination angle of the abutment block is transmitted to the rack through the gear, and then the rack is transmitted to the pointer through the indicator rod, which can amplify the inclination angle of the abutment block to a certain extent, making it more convenient for the staff to detect the specific inclination angle of the wall;

[0019] 3. The measurement of the wall inclination angle needs to be carried out multiple times at different positions. After each measurement, the abutment block needs to be reset to ensure that the abutment block is always in a vertical state when each measurement starts. At this time, the reset plate moves under the action of the reset elastic member, and the reset plate abuts against the side wall of the abutment block, thereby ensuring that the abutment block is in a vertical state. This ensures that the abutment block is in a vertical state each time the wall inclination angle is measured, which can effectively improve the accuracy of the wall inclination angle measurement.

[0052] The implementation principle of a wall verticality detection device proposed in an embodiment of the present invention is as follows:

[0053] When it is necessary to detect the inclination angle of the wall, the base 1 is pushed to the vicinity of the wall to be detected, and then the cross bar 3 is pushed toward the wall so that the abutment block 33 abuts against the wall. The abutment block 33 fits the wall. If the wall has an inclination angle, the abutment block 33 deflects. As the abutment block 33 rotates, the abutment block 33 drives the mounting shaft 32 to rotate, and the mounting shaft 32 drives the gear 42 to deflect. The gear 42 drives the rack 41 to move in the accommodating chamber 4. As the rack 41 moves, the indicator rod 44 can be driven to deflect in the bar hole 43, so that the deflection angle of the abutment block 33 can be magnified. By setting a The pointer 47, in combination with the scale 48 on the cross bar 3, can read the deflection angle of the abutment block 33, thereby completing the detection of the wall inclination angle of a point. The cross bar 3 is driven to move in the vertical direction by the lifting assembly 21, and then the deflection angle of the abutment block 33 is reset by the reset plate 61 to ensure that the abutment block 33 is in a vertical state before abutting the wall. Then, the above process is repeated to detect the wall inclination angle of the next detection point. After repeated cycles, the detection of the wall inclination angle can be completed without the need for the staff to bend over for a long time to operate, which effectively reduces the workload of the staff.
