10. A method of using a building quality testing device for construction projects according to any one of claims 1-9, characterized in that, The specific usage steps are as follows: Step 1: The equipment is stabilized on the ground by the base (1), the mounting frame (2) provides support for the lifting mechanism (3) and the hollow drum striking mechanism (4), the operator turns on the power and activates the first motor (34) and the second motor (455), so that the whole system is ready; Step 2: The limiting mechanism (5) is attached to the wall by the limiting wheel (53). After the first motor (34) is started, the drive rod (31) rotates through the first reversing gear (35) and the second reversing gear (36), thereby driving the lifting plate (32) to rise and fall in the vertical direction. The hollow drum striking mechanism (4) is also started to perform the striking operation. Step 3: When the equipment reaches the predetermined detection height, the first cylinder (39) is activated, pushing the rack (310) to mesh with the toothed ring (38), causing the rotating plate (37) to rotate appropriately, thereby adjusting the striking position of the hollow drum striking mechanism (4). At this time, the elasticity adjustment component (43) adjusts the force set by the user to ensure that the striking mark component (44) can strike the wall with appropriate force. Step 4: Under appropriate force, the extrusion plate (441) of the tapping marking assembly (44) begins to tap the wall. Under the restriction of the limiting mechanism (5), the tapping ball (445) performs a fixed-distance tapping operation and transmits a sound signal. If a hollow area is detected in the wall, the restriction of the limiting mechanism (5) will be lifted, and the device can push the entire device so that the marking rod (446) extends and marks the wall surface. Step 5: The equipment utilizes the vertical movement of the lifting mechanism (3) and the horizontal displacement function of the base (1) to cover the entire wall surface for comprehensive testing. By repeating the above steps, the comprehensive tapping test is completed.
