Description

Technical Field

[0002] Hollowing is caused by the presence of air in the original masonry and the powder ash layer. When testing, use a hollowing hammer or a hard object to tap the plaster layer and the leveling layer. If a thumping sound is heard, it is a hollowing.

A second connecting plate 28 is fixedly connected to the top of the cylinder 27. The second connecting plate 28 is fixedly connected to the rear side of the first shell 6. The height of the first shell 6 is adjusted by the cylinder 27. This is a two-stage lifting, which can be used when the first-stage lifting is not enough to lift the knocking device 13 to a higher position.

[0032] The lifting mechanism also includes a reduction motor 12, which is fixedly connected to the bottom of the first shell 6, and the output shaft of the reduction motor 12 is fixedly connected to a first threaded rod 7, which is located inside the first shell 6, and the top of the first threaded rod 7 and the top inside the first shell 6 are movably connected through a bearing, and the outer end of the first threaded rod 7 is sleeved with a first connecting plate 9, and the first threaded rod 7 and the first connecting plate 9 are connected by threads, and the front side of the first connecting plate 9 is fixedly connected with a U-shaped plate 10, which is located inside the first shell 6 and extends to the front side of the first shell 6, and the knocking device 13 is installed on the front side of the U-shaped plate 10, and two openings 11 are provided on the front side of the first shell 6, and the U-shaped plate 10 passes through the openings 11, and the lifting function of the reduction motor 12, the first threaded rod 7 and the first connecting plate 9 is coordinated, which is a first-level lifting, and the first-level lifting can be used to initially raise the height of the knocking device 13.

[0033] Two guide rods 8 distributed on the left and right are fixedly connected inside the first shell 6, the first threaded rod 7 is located between the two guide rods 8, the guide rod 8 passes through the first connecting plate 9, and the guide rod 8 and the first connecting plate 9 are slidably connected.

[0035] The knocking device 13 includes a second shell 14, which is fixedly connected to the front side of the U-shaped plate 10. A shaft 15 is movably connected to the inside of the second shell 14 through a bearing, and the shaft 15 extends to the top of the second shell 14. A U-shaped rod 16 is fixedly connected to the top of the shaft 15, and the U-shaped rod 16 is located above the second shell 14.

The second pulley 20 is located behind the first pulley 18. The motor 19 in the knocking device 13 will reciprocate the output shaft when running, so that the U-shaped rod 16 can swing left and right to alternately knock on the wall or the ground through the hammer head 17 to achieve the purpose of hollow drum detection.

[0036] The first adjustable support leg 29 includes a rectangular support rod 30, which passes through the U-shaped base 1. A plurality of second insertion holes 32 are provided on the outer side of the rectangular support rod 30. Two bolts 33 are threadedly connected on both sides of the U-shaped base 1. The ends of the bolts 33 extend into one of the second insertion holes 32. A first universal wheel 31 is fixedly connected to the bottom of the rectangular support rod 30.

[0037] The second adjustable supporting leg 34 includes an ear plate 35, which is fixedly connected to the side of the first shell 6, and a second threaded rod 36 is connected to the front side of the ear plate 35. The ear plate 35 and the second threaded rod 36 are threadedly connected, a second universal wheel 37 is fixedly connected to the front side of the second threaded rod 36, and a rotating wheel 38 is fixedly connected to the rear side of the second threaded rod 36.

[0038] The first adjustable supporting leg 29 can adjust the height of the U-shaped base 1, so that when the movable base 2 rotates ninety degrees with the shell 6 from the vertical to the horizontal state, it cooperates with the second adjustable supporting leg 34 to lift the entire device to a certain height, so that there is a certain operating space between the knocking device 13 and the ground, and the second adjustable supporting leg 34 can support the shell 6 when it is horizontal.

[0039] Working principle:

[0040] When the wall is tested for hollowing, the knocking device 13 can be driven up and down by the lifting mechanism, during which the motor 19 in the knocking device 13 drives the shaft 15 to rotate back and forth through the transmission of the second pulley 20, the belt 21 and the first pulley 18. When the shaft 15 rotates back and forth, it will drive the U-shaped rod 16 and the two hammer heads 17 on the U-shaped rod 16 to knock the wall alternately left and right, thereby realizing the hollowing detection of the wall;

[0041] When the lifting mechanism is in operation, the first threaded rod 7 is driven to rotate by the reduction motor 12 in the early stage. When the first threaded rod 7 rotates, it can move the first connecting plate 9 and the U-shaped plate 10 up and down along the first threaded rod 7, thereby driving the knocking device 13 to move up and down. When detecting a higher wall, after the knocking device 13 rises to the highest point in front of the first shell 6, the cylinder 27 behind the first shell 6 can be started, and the cylinder 27 pushes the second connecting plate 28 to move the first shell 6 upward as a whole. When the first shell 6 moves upward, it is supported and guided by the guide mechanism. The first shell 6 slides upward on the T-shaped slide rail 23 through the rear sliding sleeve 22 to prevent the first shell 6 from tilting.

[0042] When it is necessary to perform a hollow drum test on the ground after detecting the wall, the latch 5 can be pulled out first. At this time, the movable base 2 can be rotated on the U-shaped base 1 through the shaft column 3, until the first shell 6 on the movable base 2 is rotated ninety degrees from vertical to horizontal, and the latch 5 is reinserted. At this time, the latch 5 is inserted into the first plug hole 4 on the shaft column 3 to restrict and lock the shaft column 3 again. At this time, the movable base 2 can no longer rotate, and the first shell 6 on the movable base 2 can only maintain a horizontal state. During this period, the height of the U-shaped base 1 and the first shell 6 can be adjusted by the first adjustable supporting leg 29 and the second adjustable supporting leg 34 until a certain operating space is maintained between the knocking device 13 on the first shell 6 and the ground. The same operation is performed as the way of knocking on the wall. At this time, the knocking device 13 can perform a hollow drum knocking test on the ground;

[0043] When adjusting the first adjustable support leg 29, it is only necessary to first unscrew the bolt 33 so that the rectangular support rod 30 is no longer restricted. At this time, the rectangular support rod 30 can be moved down to raise the U-shaped base 1, and then the bolt 33 is re-screwed so that the bolt 33 is inserted into the adjacent second insertion hole 32 on the rectangular support rod 30 to complete the fixing of the first adjustable support leg 29;

[0044] When adjusting the second adjustable support leg 34, one only needs to hold the rotating wheel 38 and rotate the second threaded rod 36, so that the second threaded rod 36 gradually moves away from the ear plate 35 with the second universal wheel 37 until the second universal wheel 37 falls to the ground, and the ear plate 35 can support the first housing 6 on the second threaded rod 36 to be horizontal to the ground;

[0045] Whether it is wall hollow drum knocking detection or ground hollow drum knocking detection, it can be moved. When detecting the wall, it is mainly through the first adjustable supporting leg 29, and when detecting the ground, the first adjustable supporting leg 29 and the second adjustable supporting leg 34 need to be used in conjunction.
