Description

Technical Field

[0001] The utility model belongs to the technical field of engineering detection, in particular to a hollowing detection device for civil construction. Background Art

[0002] The hollowing phenomenon is caused by the presence of air between the original masonry and the powder ash layer. During engineering inspection, use a hollowing hammer or a hard object to gently tap the plaster layer and the leveling layer. If a thumping sound is heard, it indicates that there is a hollowing. When observed with the naked eye, the hollow part is usually slightly higher than the surrounding overall plane and is often accompanied by cracks. You can feel the internal cavity by lightly pressing with your fingers. When tapping the wall, a hollowing detection hammer is an essential tool.

[0003] The existing hollow drum detection hammer is simple in design, light and easy to carry. When using it, you only need to hold the handle, swing it and hit the wall, and you can judge whether there is a hollow drum by the feedback sound.

[0004] However, the structure of this hollowing detection hammer is relatively simple and has some shortcomings. After the hollowing is found, it is necessary to mark it with a marker pen immediately, but errors are prone to occur in this process, resulting in inaccurate marking positions. In addition, the length of its rod is limited. When it is necessary to detect high walls, a ladder must be used, which undoubtedly reduces the detection efficiency. Utility Model Content

[0007] The base is fixedly connected to the hollow tube, a motor is arranged in the hollow tube, a slide groove is arranged on the inner wall of the hollow tube along the length direction, the output shaft of the motor is fixedly connected to the threaded rod, the threaded rod is threadedly connected to the internal threaded tube, the internal threaded tube is slidingly limitedly connected to the slide groove, the upper end of the internal threaded tube is fixedly connected to a fixed block, the fixed block is fixedly connected to the outer wall of the fixed ring, an end face of the fixed ring is fixedly connected to the inner gear ring, the inner gear ring is meshedly connected to the marking mechanism, an end face of the fixed ring is provided with an annular groove along the circumferential direction, the marking mechanism is slidably connected to the annular groove, and a knocking mechanism is arranged on one side wall of the fixed block.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0023] Each of the clamping units includes a fixing block 12, a top screw 13 and a clamping plate 14;

[0024] The second fixing block 12 is fixedly connected to the slider 10 . A threaded hole is provided on the second fixing block 12 . One end of the top screw 13 rotates through the threaded hole and is rotatably connected to the clamping plate 14 . The clamping plate 14 is slidably arranged to fit the slider 10 .

[0025] The knocking mechanism includes a knocking hammer 15, a torsion spring 16, a fixing bar 17, a cam 18, a fixing bar 2 19 and a motor 3;

[0026] The knocking hammer 15 is connected to the fixing bar 17 through the torsion spring 16, the fixing bar 17 is fixedly connected to the fixing block 7, one end of the fixing bar 2 19 is fixedly connected to the fixing block 7, the other end of the fixing bar 2 19 is fixedly connected to the motor 3, the output shaft of the motor 3 is fixedly connected to the cam 18, and the cam 18 is used in conjunction with the knocking hammer 15.

[0027] The base 1 is provided with a switch button 2, and the switch button 2 is electrically connected to the motor 1 4, the motor 2 and the motor 3 respectively.

[0028] When using the utility model, the handheld base 1 is moved to the preset position where the hollow drum needs to be detected, and the motor 4 is started by the switch button 2. The motor 4 rotates the threaded rod 5.

Through continuous knocking and resetting actions, the wall or the ground can be detected. Whether there is a hollow drum on the surface, when a hollow drum is found during the knocking process, the motor 2 is started by the switch button 2, and the motor 2 rotates the gear 11. Since the gear 11 is meshed with the inner ring 9, the rotation of the gear 11 drives the slider 10 to slide in the annular groove of the fixed ring 8. The brush in the clamping unit installed on the slider 10 moves with the slider 10, and a line is drawn at the hollow drum position, and the hollow drum position is circled for marking. The top screw 13 in the clamping unit can be rotated. By adjusting the tightness of the top screw 13, brushes of different thicknesses can be easily replaced or fixed to meet different marking requirements. The operation process of the entire device is controlled by the switch button 2 on the base 1, and the switch button 2 is electrically connected to the motor 1 4, the motor 2 and the motor 3 respectively.
