Description

Technical Field

[0001] This utility model relates to the technical field of wall detection devices, specifically a wall hollow detection device. Background Technology

[0002] The performance of a building is closely related to the quality of its wall materials or panels. Quality inspection is an indispensable and important part of production and application, especially the detection of hollow walls. A special testing device is used to tap the wall and the auditory feedback is used to determine whether there is a hollow wall. If the tapping sound is hollow and has a clear echo, it indicates that there may be a hollow problem. The hollow part of the wall needs to be removed and repainted or re-tiled.

[0003] For example, a wall hollow detection device with publication number CN219417340U relates to the field of hollow hammer technology. It includes a fixed tube with a sponge sleeve fixedly installed on its outer side. A first hollow hammer telescopic tube is inserted inside the fixed tube, a second hollow hammer telescopic tube is inserted inside the first hollow hammer telescopic tube, and a third hollow hammer telescopic tube is inserted inside the second hollow hammer telescopic tube. A first, second, third, fourth, and fifth marker telescopic tubes are fixedly installed inside the fixed tube. When the fixed tube, the first, second, third, and fourth hollow hammer telescopic tubes are stretched, they are all stretched together. When the hollow hammer strikes a higher part of the wall, the marker pen can be moved out of its mounting hole by adjusting the ring in conjunction with the fifth marker telescopic tube, thus facilitating the marking of hollow locations at higher levels of the wall using the entire telescopic tube structure.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the device can detect wall voids, the overall device is rod-shaped and requires the operator to hold it by hand. When conducting area detection on a wall, the operator needs to frequently change the position of the device to perform the detection, which reduces the detection efficiency. At the same time, since the device is manually held, it is difficult to guarantee the consistency of the striking force, angle, and position when conducting area detection on a wall, resulting in insufficient detection accuracy.

[0005] Therefore, a wall hollow detection device is proposed to address the above problems. Utility Model Content

A card holder is fixedly installed at the end of the output end of the electric telescopic rod, and a marking component is provided inside the card holder.

[0011] Preferably, the inner walls of the upper and lower sides of the U-shaped outer frame are provided with U-shaped grooves, and limit rods are fixedly installed inside the U-shaped grooves. Limit blocks are fixedly installed on the upper and lower sides of the vertical truss, and the limit blocks are sleeved onto the surface of the limit rods.

[0012] Preferably, a threaded sleeve is fixedly installed at the middle part of the back of the vertical truss, and the threaded sleeve is threadedly engaged with the first threaded rod. A handle is fixedly installed on the back of the U-shaped outer frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the structural design of a U-shaped outer frame, vacuum suction cup, horizontal truss, stepper motor, vertical truss, and servo motor, and through the cooperation between the structures, realizes the function of wall area detection.

The rotation of the eccentric block drives the hollow hammer to strike the wall, simulating the action of manually striking the wall with a hollow hammer. It can also ensure that the rhythm and force of each strike are relatively uniform, thus ensuring accurate detection of the hollowness of the wall and solving the problem of insufficient accuracy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a wall hollow detection device, including a U-shaped outer frame 1. Connecting ears 2 are fixedly installed at each of the four corners of the U-shaped outer frame 1. A vacuum suction cup 3 is fixedly installed on the front of the connecting ears 2. A pull handle 301 is movably installed inside the vacuum suction cup 3. A horizontal truss 4 is fixedly installed on the back of the U-shaped outer frame 1. A stepper motor 5 is fixedly installed on one side of the horizontal truss 4. The output end of the stepper motor 5 is set as a first threaded rod 6. A vertical truss 7 is movably installed on the surface of the first threaded rod 6. A servo motor 8 is fixedly installed on the top of the vertical truss 7. The output end of the servo motor 8 is set as a second threaded rod 9. An assembly frame 10 is movably installed on the surface of the second threaded rod 9. A hollow hammer 11 is provided inside the assembly frame 10.

[0026] Reference Figure 1 , Figure 2 , Figure 3 Through the structural design of the U-shaped outer frame 1, vacuum suction cup 3, horizontal truss 4, stepper motor 5, vertical truss 7, and servo motor 8, and through the cooperation between the structures, the function of wall area detection is realized. Thus, the movement of the hollow hammer 11 in the horizontal and vertical directions can be precisely adjusted by rotating the first threaded rod 6 and the second threaded rod 9, eliminating the need for manual tapping of each position, greatly improving detection efficiency and reducing labor costs and labor intensity.

[0027] A drive motor 12 is fixedly installed on one side of the assembly frame 10, and an eccentric block 13 is fixedly installed at the end of the output end of the drive motor 12.

[0028] Reference Figure 3 and Figure 4 Through the structural design of the drive motor 12 and the eccentric block 13, the function of automatically tapping the wall is realized. Thus, the rotation of the eccentric block 13 can drive the hollow hammer 11 to tap the wall, simulating the action of manually tapping the wall with the hollow hammer 11. It can also ensure that the rhythm and force of each tap are relatively uniform, thus ensuring accurate detection of the hollowness of the wall.

[0029] A T-shaped rod 14 is fixedly installed in the middle part of the eccentric block 13. A spring 15 is sleeved on the surface of the T-shaped rod 14. A hollow hammer 11 is deployed on the surface of the T-shaped rod 14 and outside the spring 15.

[0030] Reference Figure 4 The T-shaped rod 14 facilitates the limiting of the hollow hammer 11, thereby ensuring the movement path of the hollow hammer 11. The spring 15 facilitates the use of its contraction characteristics to provide the hollow hammer 11 with a space for movement, thereby reducing the wear of the hollow hammer 11. At the same time, its tension can also be used to push the hollow hammer 11 to quickly reset.

[0031] A sound detection sensor 16 is fixedly installed at the middle part of the top of the assembly frame 10. An electric telescopic rod 17 is fixedly installed on the other side of the back of the assembly frame 10. A card holder 18 is fixedly installed at the end of the output end of the electric telescopic rod 17. A marking component 19 is provided inside the card holder 18.

[0032] Reference Figure 3 The sound detection sensor 16 can detect the sound signal generated when the hollow hammer 11 hits the wall, thereby analyzing the frequency, timbre and other characteristics of the sound to determine whether there is a hollow in the wall. Then, the electrical signal can be transmitted to the electric telescopic rod 17. The electric telescopic rod 17, the bracket 18 and the marking component 19 can be used to apply color markings to the wall, thereby marking the location of the hollow in the wall.

[0033] The inner walls of the upper and lower sides of the outer frame 1 are provided with U-shaped grooves 20. Limiting rods 21 are fixedly installed inside the U-shaped grooves 20. Limiting blocks 22 are fixedly installed on the upper and lower sides of the vertical truss 7. The limiting blocks 22 are sleeved onto the surface of the limiting rods 21.

[0034] Reference Figure 1 and Figure 2 The U-shaped groove 20 and the limiting rod 21 facilitate the cooperation with the limiting block 22 to ensure the stability of the vertical truss 7 during movement, and avoid the influence of the rotation of the first threaded rod 6 on the vertical truss 7 during movement.

[0035] A threaded sleeve 23 is fixedly installed in the middle part of the back of the vertical truss 7. The threaded sleeve 23 is threadedly engaged with the first threaded rod 6. A handle 24 is fixedly installed on the back of the U-shaped outer frame 1.

[0036] Reference Figure 1 and Figure 2 The threaded sleeve 23 facilitates the engagement with the first threaded rod 6 to ensure that the stepper motor 5 accurately controls the movement of the vertical truss 7. The handle 24 facilitates the handheld operation of the device by the staff, so as to achieve the purpose of rapid deployment and movement of the entire device.

[0037] The hollow hammer 11 has a sliding cavity 25 in the middle part.

[0038] Reference Figure 4 The sliding cavity 25 facilitates the movement space at the end of the T-shaped rod 14, thereby ensuring that the hollow hammer 11 can degrade the impact force through movement when it is subjected to force.

[0039] Working principle: When using this device, the operator holds the handle 24 and moves the device to the wall to be inspected. Pulling the pull handle 301 extracts the air from the vacuum suction cup 3, firmly adhering the device to the wall surface. The stepper motor 5 is started, causing the vertical truss 7 to move laterally to the appropriate position under the drive of the first threaded rod 6. Then, the servo motor 8 is started, causing the assembly frame 10 to move vertically to the target inspection point under the drive of the second threaded rod 9. The drive motor 12 is started, and the eccentric block 13 rotates, driving the T-shaped rod 14 and the hollow hammer 11 to strike the wall. The sound detection sensor 16 detects the striking sound signal in real time and transmits the signal to the control system for analysis and judgment. If the control system determines that there is a hollow in the wall, it controls the electric telescopic rod 17 to extend, causing the marking component 19 to contact the wall and mark it. According to the preset detection path, the positions of the vertical truss 7 and the assembly frame 10 are adjusted in sequence, and the striking, detection and marking operations are repeated until the entire wall area is inspected.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
