Description

Technical Field

[0001] The utility model relates to the technical field of wall quality detection, in particular to a hollowing detection device for a house wall. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and fly ash layers, which leads to hollowing between the floor, wall, ceiling decoration layer and the structural layer of the house due to loose adhesion and bonding.

[0003] The principle of using a hollow hammer to detect whether a wall is hollow is to use the hollow hammer to knock on the wall surface and judge whether there is a hollow phenomenon by the sound. When the hollow hammer or a hard object taps the plaster layer and the leveling layer, if a dull and loud sound is made, there is a high probability that a "hollow" problem has occurred.

[0004] In the prior art, the action of hitting the wall with a hollow hammer is manually operated, and the force and speed of each hit are different. Even at the same point, the sound generated each time is different. Therefore, it is not possible to better judge the extent of the hollowing problem here. Therefore, a new hollowing detection device for the wall of a house is proposed. The knocking action of the hollow hammer is automatically generated, and the force and speed of each knock are the same, which effectively solves the problems existing in the prior art.

[0008] A switch is provided on the outer surface of the main section, and the end of the locking pin abuts against the outer surface of the telescopic section;

[0009] A joint is fixedly connected to the side of the telescopic joint, a constant torque motor is fixedly connected to the top of the joint, a swivel is fixedly connected to the output end of the constant torque motor, and a rod body is fixedly connected to the outer surface of the swivel;

[0010] The end of the rod body is fixedly connected with a hammer head;

[0011] The outer side of the constant torque motor is fixedly connected with a sound pickup lamp.

[0012] Preferably, any of the above schemes is that the main section and the telescopic section are both made of aluminum alloy, and the main sleeve is bonded to the outer surface of the main section.

[0013] Adopting the above technical solution: This device is specially used for hollowing detection of walls and is a handheld tool.

[0014] Preferably, any of the above schemes has a constant torque motor and a power supply battery for the sound pickup light built into the telescopic joint.

[0015] Adopting the above technical solution: the switch is electrically connected to the control board of the constant torque motor, the constant torque motor can be started, and the pickup lamp is always on.

[0016] Preferably, in any of the above schemes, the main sleeve is made of rubber, and the outer end of the locking pin is fixedly connected to a knob.

[0017] Adopting the above technical solution: this device does not need to knock on the wall manually, but uses a constant torque motor to drive the rod body to rotate, so that the hammer head knocks on the wall, and the knocking sound is used to judge the hollow condition of the wall at this point. The hammer head is a solid metal ball.

[0018] Preferably, any of the above schemes is that the joint is welded to the expansion joint or connected by screws, the bending angle of the joint is ninety degrees, and the joint is welded to the constant torque motor or connected by screws.

[0019] The above technical solution is adopted: the design of constant torque motor has stable speed and torque output, so that each time the hammer hits the wall, it has constant speed and force, ensuring that the results of each hollow drum detection in the wall have good reliability.

[0020] The design of the pickup light allows the volume of the hammer hitting the wall to be displayed intuitively on the pickup light. The higher the light column on the pickup light, the louder the volume and the more serious the hollowing problem. Hollowing is caused by the presence of air or low-density material between the plaster layer and the wall base. The louder the volume when the hammer hits, the lower the light column on the pickup light, which means the volume is small, and the hollowing problem is small or there is no hollowing. The design of the pickup light allows technicians to intuitively judge the size of the wall hollowing problem.

[0021] The working principle of the pickup lamp is that the pickup lamp has a microphone. The sound is transmitted to the microphone. The internal chip of the pickup lamp can automatically control the switch and brightness of the light according to the strength of the sound signal, thereby achieving an intuitive detection effect.

Hollowing is caused by the presence of air or low-density material between the plaster layer and the wall base. The louder the volume when the hammer hits, the lower the light column on the pickup light, which means the volume is small, and the hollowing problem is small or there is no hollowing. The design of the pickup light allows technicians to intuitively judge the size of the wall hollowing problem.
