Description

Technical Field

[0001] This application relates to the field of hollow detection technology, and more specifically, to a hollow detection device for quality supervision of construction projects. Background Technology

[0002] Hollow spots are caused by air trapped in the original masonry and plaster layers. During testing, a hollow sound is produced by gently tapping the plaster and leveling layers with a hollow spot hammer or a hard object. In terms of building quality, "hollow spots" generally refer to the phenomenon where the floor, wall, and ceiling finishing layers (plaster or tiled surfaces) are not firmly bonded to the structural layers (concrete or brick walls), commonly known as "two layers of skin." To ensure the quality of the building project, hollow spot testing is required after construction.

[0003] Existing technology publication CN214539169U provides a hollow detection device for building engineering, including a connecting rod and a detection hammer. The connecting rod includes rod one, rod two, and rod three. The bottom of rod two is hinged to the top of rod one, and the rotation center line of rod two is perpendicular to the axis of rod one. A positioning element one for fixing the position of rod two is provided on rod one. A movable groove is provided inside rod two, which is arranged along the length of rod two. One end of rod three is slidably installed inside rod two, and the other end extends to the outside of the movable groove. A positioning block for fixing the position of rod three is movably installed on rod three, and a locking hole that mates with the positioning block is provided inside rod two. This application has the effect of facilitating the adjustment of the length of the detection device.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] Simply adjusting the length of multiple rods by sliding them requires repeatedly lifting the hammer head to strike the wall when inspecting tall walls. When the rods are very long, the lever arm length is increased, which requires a lot of force to lift the hammer head. Repeated lifting and striking will accelerate arm fatigue.

[0006] Regarding the aforementioned related technologies, the inventor believes that simply adjusting the length by sliding multiple rods requires repeatedly lifting the extended rod to strike the wall when inspecting tall walls. When the rod is very long, increasing the lever arm length requires a lot of force to lift the hammer, and repeated lifting and striking will accelerate arm fatigue.

[0007] In view of this, we propose a hollow detection device for quality supervision of building engineering. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide a hollow detection device for quality supervision of building engineering, which solves the technical problems in the above-mentioned background technology, which simply adjusts the length by sliding multiple rods. When inspecting high walls of buildings, it is necessary to hold the extended rods and repeatedly lift the hammer head to strike the wall. When the rods are very long, the lever arm length is increased. Lifting the hammer head requires a lot of force, and repeated lifting and striking will accelerate the fatigue of the operator's arm. This application achieves the technical effect.

[0010] 2. Technical Solution

[0011] This application provides a hollow detection device for quality supervision of building engineering, comprising:

[0012] handle;

[0013] A telescopic rod, wherein a telescopic rod is installed at one end of the handle;

[0014] The telescopic rod is hinged to the U-shaped seat at the end away from the handle;

[0015] Rollers are rotatably mounted on both sides of the U-shaped seat;

[0016] The testing mechanism is installed inside the cavity of the U-shaped seat.

[0017] The above scheme adjusts the length of the telescopic rod according to the height of the building wall to be inspected. The inspector holds the handle and moves away from the wall to get closer to it. The U-shaped seat is pushed along the wall from bottom to top by the handle and the telescopic rod. The roller rolls against the wall and simultaneously drives the inspection mechanism to knock on the wall, realizing the inspection of the wall from bottom to top, achieving multi-point inspection, and avoiding the laborious process of repeatedly lifting the device to knock on the high part of the wall.

[0018] Optionally, the telescopic rod includes a sliding cylinder, one end of which is slidably sleeved inside the handle, and the other end of which is slidably sleeved with a sliding rod. Multiple clamping plates are fixedly installed at the ends of the handle and the sliding cylinder. Locking nuts are movably sleeved on the sliding cylinder and the sliding rod. The locking nuts are threaded to the outer wall of the clamping plates. The clamping plates are evenly distributed along the circumference of the handle and the sliding cylinder. The clamping plates are elastic arc-shaped structures, and the outer wall of the clamping plates and the inner wall of the locking nuts are both frustum-shaped inclined structures, with the small-diameter end of the frustum-shaped inclined structure close to the U-shaped seat.

[0019] By loosening the locking nut, the clamping plate is in its natural state, allowing the sliding cylinder and slide rod to be pushed and pulled to adjust the length. Then, tightening the locking nut causes it to press against the clamping plate through the truncated cone, thus clamping the sliding cylinder and slide rod to achieve locking and adjust the length of the telescopic rod.

[0020] Optionally, the detection mechanism includes a sliding frame, with a sliding frame slidably mounted on one inner wall of the U-shaped seat. First racks are fixedly mounted on both inner walls of the sliding frame. Wheel axles are rotatably sleeved on both sides of the U-shaped seat. Rollers are fixedly sleeved on the wheel axles. One end of one wheel axle extends into the inner cavity of the sliding frame and is fixedly sleeved with a half-gear. The half-gear meshes with the first rack. A rotating shaft is rotatably sleeved between the inner walls of the U-shaped seat. A rocker gear is fixedly sleeved at one end of the rotating shaft. A second rack is fixedly mounted on one side of the sliding frame, meshing with the rocker gear. One end of multiple elastic rods is fixedly connected to the rotating shaft. A hammer ball is fixedly mounted at the other end of each elastic rod. A guide rail is fixedly mounted on the U-shaped seat. The side of the sliding frame away from the second rack slidably engages with the guide rail. The elastic rods are elastic spiral structures.

[0021] With the above solution, when the inspector pushes the U-shaped seat along the wall using the handle and telescopic rod, the roller rolls along the wall, and the axle drives the half gear to rotate continuously. The half gear alternately meshes with the two first racks, causing the sliding frame to slide back and forth along the guide rail. The second rack then causes the rocking gear to rotate back and forth, and the rocking gear drives the rotating shaft to rotate back and forth. The elastic rod then swings back and forth, causing the hammer ball to repeatedly strike the wall, thus achieving multiple strikes to the top and bottom of the wall for inspection. The inspection is convenient and labor-saving.

[0022] 3. Beneficial effects

[0023] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0024] 1. This application allows for testing by having the U-shaped seat moved along the wall by the tester using the handle and telescopic rod. The rollers roll along the wall, causing the axle to drive the half gear to rotate continuously. The half gears alternately mesh with the two first racks, causing the sliding frame to slide back and forth along the guide rail. The second rack then causes the rocking gear to rotate back and forth, which in turn drives the rotating shaft to rotate back and forth. This causes the elastic rod to swing back and forth, causing the hammer ball to repeatedly strike the wall, thus achieving multiple strike tests on the wall. The testing is convenient and labor-saving. Attached Figure Description

Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 This application provides a hollow detection device for construction engineering quality supervision, comprising: a handle 1; a telescopic rod 2, one end of which is mounted with the telescopic rod 2; a U-shaped seat 3, the end of the telescopic rod 2 away from the handle 1 being hinged to the U-shaped seat 3; rollers 4, both sides of the U-shaped seat 3 being rotatably mounted with rollers 4; and a detection mechanism 5, which is installed in the inner cavity of the U-shaped seat 3. The length of the telescopic rod 2 is adjusted according to the height of the building wall to be detected. The inspector holds the handle 1 and moves it away from the wall and closer to the wall. The handle 1 and the telescopic rod 2 push the U-shaped seat 3 to move from bottom to top along the wall. The rollers 4 roll against the wall and simultaneously drive the detection mechanism 5 to strike the wall, realizing wall detection from bottom to top, achieving multi-point detection, and avoiding the laborious process of repeatedly lifting the device to strike high parts of the wall.

[0031] Reference Figure 1 and Figure 2 The telescopic rod 2 includes a sliding cylinder 21, one end of which is slidably sleeved inside the handle 1, and the other end of which is slidably sleeved with a sliding rod 22. Multiple clamping plates 23 are fixedly installed at the ends of both the handle 1 and the sliding cylinder 21. Locking nuts 24 are movably sleeved on both the sliding cylinder 21 and the sliding rod 22, and the locking nuts 24 are threaded onto the outer walls of the clamping plates 23. The clamping plates 23 are evenly distributed along the circumference of the handle 1 and the sliding cylinder 21, and the clamping plates 23 have an elastic arc-shaped structure. Furthermore, both the outer wall of the clamping plate 23 and the inner wall of the locking nut 24 are frustum inclined structures, and the small diameter end of the frustum inclined structure is close to the U-shaped seat 3. When the locking nut 24 is loosened, the clamping plate 23 is in a natural state, which can push and pull the sliding cylinder 21 and the sliding rod 22 to adjust the length. Then, the locking nut 24 is tightened, and the locking nut 24 presses the clamping plate 23 through the frustum inclined surface, so that the clamping plate 23 clamps the sliding cylinder 21 and the sliding rod 22 to achieve locking and achieve the purpose of adjusting the length of the telescopic rod 2.

[0032] Reference Figure 1 and Figure 3The detection mechanism 5 includes a sliding frame 51. A sliding frame 51 is slidably mounted on one inner wall of a U-shaped seat 3. First racks 52 are fixedly mounted on both inner walls of the sliding frame 51. Wheel axles 53 are rotatably sleeved on both sides of the U-shaped seat 3. Rollers 4 are fixedly sleeved on the wheel axles 53. One end of one wheel axle 53 extends into the inner cavity of the sliding frame 51 and is fixedly sleeved with a half-gear 54. The half-gear 54 meshes with the first rack 52. A rotating shaft 55 is rotatably sleeved between the inner walls of the U-shaped seat 3. A rocker gear 56 is fixedly sleeved on one end of the rotating shaft 55. A second rack 57 is fixedly mounted on one side of the sliding frame 51. The second rack 57 meshes with the rocker gear 56. One end of multiple elastic rods 58 is fixedly connected to the rotating shaft 55. The other end of the elastic rods 58... A hammer ball 59 is fixedly installed at one end, and a guide rail 6 is fixedly installed on the U-shaped seat 3. The side of the sliding frame 51 away from the second rack 57 is slidably engaged with the guide rail 6. The elastic rod 58 is an elastic spiral structure. When the inspector pushes the U-shaped seat 3 along the wall through the handle 1 and the telescopic rod 2, the roller 4 rolls along the wall, and the wheel axle 53 drives the half gear 54 to rotate continuously. The half gear 54 alternately meshes with the two first racks 52, causing the sliding frame 51 to slide back and forth along the guide rail 6. Then the second rack 57 causes the rocking gear 56 to rotate back and forth. The rocking gear 56 drives the rotating shaft 55 to rotate back and forth, and the elastic rod 58 swings back and forth, causing the hammer ball 59 to repeatedly strike the wall, thereby realizing multiple strikes on the wall, making the inspection convenient and labor-saving.

[0033] Working principle: Loosening the locking nut 24 puts the clamping plate 23 in its natural state, allowing the sliding cylinder 21 and sliding rod 22 to be pushed and pulled to adjust the length. Then, tightening the locking nut 24 causes the clamping plate 23 to be pressed against the truncated cone by the inclined surface of the locking nut 24, thus clamping the sliding cylinder 21 and sliding rod 22 to achieve locking and achieve the purpose of adjusting the length of the telescopic rod 2. When the inspector pushes the U-shaped seat 3 along the wall using the handle 1 and the telescopic rod 2, the roller 4 rolls along the wall, and the axle 53 drives the half gear 54 to rotate continuously. The half gear 54 alternately meshes with the two first racks 52, causing the sliding frame 51 to slide back and forth along the guide rail 6. The second rack 57 then causes the rocking gear 56 to rotate back and forth. The rocking gear 56 drives the rotating shaft 55 to rotate back and forth, causing the elastic rod 58 to swing back and forth, causing the hammer ball 59 to repeatedly strike the wall, thus achieving multiple strikes to the top and bottom of the wall for testing. The testing is convenient and labor-saving.
