Description

Technical Field

[0001] This application relates to the field of wall hollow detection technology, and in particular to a device for detecting hollow walls in building construction. Background Technology

[0002] In the construction industry, hollow wall detection devices are often used to check for hollow areas in walls. These devices typically consist of a hammer handle and a hammer head. When inspecting a wall, the hammer handle is held, and the hammer head is gently struck against the wall. The presence of hollow areas can be determined based on the sound heard.

[0003] Chinese patent CN218629638U discloses a hollow wall detection device. This patent includes a base plate and a third electrically operated telescopic rod located above the base plate. A first electrically operated telescopic rod is mounted on the top of the base plate. A fixing tube is installed at the telescopic end of the first electrically operated telescopic rod. A mounting plate is detachably mounted on one side of the fixing tube. A second electrically operated telescopic rod is mounted on one side of the mounting plate. A metal head is installed at the telescopic end of the second electrically operated telescopic rod. Bolts are mounted on the mounting plate, and the mounting plate is connected to the fixing tube via bolts. This hollow wall detection device, by activating the first electrically operated telescopic rod, causes its telescopic end to move the metal head upwards. Activating the second electrically operated telescopic rod causes its telescopic end to continuously extend and retract, thereby causing the metal head to repeatedly strike the wall. This achieves the effect of detecting hollow walls at higher elevations, facilitating inspections of these areas and ensuring comprehensive detection of hollow walls.

[0004] However, if the wall being inspected has hollow areas, workers need to mark the locations of these hollow areas promptly. When the hollow areas are located at higher positions on the wall, workers need to use an A-frame ladder to mark the locations of the hollow areas. This reduces the efficiency of detecting and marking hollow areas on the wall. Furthermore, manually marking the locations of hollow areas on the wall using an A-frame ladder poses a safety risk due to working at height, which is clearly inadequate. Utility Model Content

[0005] In order to improve the efficiency of marking hollow areas on walls and reduce the risks to workers during marking, this application provides a device for detecting hollow areas in interior walls during building construction.

[0006] The technical solution of the indoor wall hollow detection device provided in this application is as follows:

[0007] A device for detecting hollow spots in interior walls during building construction includes a handle, a telescopic rod coaxially mounted on the handle, a hollow spot detection head mounted on the end of the telescopic rod away from the handle, a marking assembly on the outer surface of the telescopic rod away from the handle, the marking assembly including a fixing ring fixedly sleeved on the outer surface of the telescopic rod, two support rods mounted on the fixing ring, a fixing block mounted on the two support rods, a connecting cylinder mounted on the inner wall of the fixing block, a marking pen slidably connected inside the connecting cylinder, and a fastening assembly mounted on the connecting cylinder, the marking pen being fixed inside the connecting cylinder by the fastening assembly.

[0008] By adopting the above technical solution, before testing, the marking pen is inserted into the connecting cylinder and fixed with the fastening component. After the marking pen is fixed, the worker taps the wall with the hollow detection head. When a hollow phenomenon is detected, the worker rotates the telescopic rod through the handle to make the marking pen face the wall, and then marks the wall with the marking pen. This setup enables rapid marking of the wall without the need for workers to use tools such as A-frame ladders, improving the efficiency of hollow detection and marking of the wall, while reducing the risk to workers during marking.

[0009] Optionally, the fastening assembly includes a threaded ring disposed on the outer surface of the connecting cylinder, the threaded ring being configured to communicate with the interior of the connecting cylinder, a screw being internally threaded onto the threaded ring, a clamping block being disposed at the end of the screw near the marker pen, and a gripping block being disposed at the other end, the clamping block and the gripping block having circular cross-sections.

[0010] By adopting the above technical solution, after the marking pen is inserted into the connecting cylinder, the worker rotates the gripping block to make the screw rotate. During the rotation of the screw, the clamping block moves towards the marking pen. When the clamping block is pressed against the outer surface of the marking pen, the rotation of the gripping block is stopped. The clamping action of the clamping block on the marking pen achieves the fixation of the marking pen in the connecting cylinder, preventing the marking pen from coming out of the connecting cylinder during the marking process. At the same time, it prevents the marking from shifting due to vibration during the detection process, thus ensuring the accuracy of the marking work.

[0011] Optionally, the inner wall of the connecting cylinder is provided with a contact pad, and the cross-section of the contact pad is annular.

[0012] By adopting the above technical solution, when the marker pen comes into contact with the inner wall of the connecting cylinder, the contact pad installed on the inner wall of the connecting cylinder increases the friction between the marker pen and the connecting cylinder, thereby further improving the stability of the marker pen between the connecting cylinders.

[0013] Optionally, the gripping block is provided with multiple anti-slip grooves, which are evenly distributed on the outer surface of the gripping block.

[0014] By adopting the above technical solution, the anti-slip groove can increase the friction between the grip block and the worker's hand, avoid slippage and failure to rotate, and thus improve the efficiency of rotating the screw.

[0015] Optionally, an auxiliary component is provided at the end of the telescopic rod near the hollow detection head. The auxiliary component includes a fixing plate, which is fixedly sleeved on the outer surface of the telescopic rod. The fixing plate has a fixing groove. The bottom surface of the hollow detection head has an assembly block that slides with the fixing groove. Both the fixing plate and the assembly block have interconnected pin holes. An insert rod is slidably connected in the pin hole. A spring is sleeved on the outer surface of the insert rod. One end of the spring is located on the outer surface of the fixing plate, and the other end is located on the outer surface of the insert rod. In the spring's natural state, the insert rod passes through the pin hole and penetrates the fixing plate and the assembly block.

[0016] By adopting the above technical solution, when a damaged hollow detection head needs to be replaced, the worker pulls the insertion rod outward to keep it detached from the assembly block and the fixing plate. At this time, the spring is stretched, and the damaged hollow detection head is then removed from the fixing plate. After removal, the assembly block on the new hollow detection head is inserted into the fixing groove, ensuring that the pin hole is aligned. Finally, the insertion rod is released, and the spring returns to its original position, causing the insertion rod to pass through the pin hole in the assembly block and the fixing plate. The new hollow detection head is then installed. The auxiliary components enable the rapid replacement of the hollow detection head, ensuring the detection effect of the hollow detection head.

[0017] Optionally, the outer surface of the assembly block is provided with a plurality of limiting blocks, and the inner sidewall of the fixing groove is provided with limiting grooves corresponding to the plurality of limiting blocks. When the limiting block is slidably connected in the corresponding limiting groove, the pin hole on the fixing plate is connected to the pin hole of the assembly block.

[0018] By adopting the above technical solution, when installing the hollow detection head, the worker only needs to slide the limiting block into the corresponding limiting groove to achieve the positioning of the assembly block and the pin hole on the fixed plate, avoiding the time-consuming manual alignment, and preventing circumferential displacement of the detection head during operation, thus improving the convenience for workers when installing the hollow detection head.

[0019] Optionally, a guide block is provided at the end of the insertion rod away from the spring, and the end face of the guide block is arc-shaped.

[0020] By adopting the above technical solution, during the insertion of the insertion rod, the guide block reduces the resistance when the insertion rod is inserted, guides the insertion rod to accurately enter the pin hole of the assembly block and the fixing plate, avoids wear of the insertion rod due to misalignment, and further improves the assembly and disassembly efficiency.

[0021] Optionally, a pull ring is provided at the end of the insertion rod near the spring.

[0022] By adopting the above technical solution, when it is necessary to pull the insertion rod out of the fixed plate, the pull ring installed on the insertion rod can be used to pull the insertion rod. The pull ring makes it easy to operate the insertion rod compression spring with one hand, so as to quickly unlock the detection head.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This embodiment of the application sets up a marking component and a fastening component. Before the test, the marking pen is placed inside the connecting cylinder and fixed by the fastening component. When a hollow phenomenon is found, the worker rotates the telescopic rod so that the marking pen faces the wall, and then marks the wall with the marking pen. This setting realizes the rapid marking of the wall without the need for workers to use tools such as A-frame ladders to mark, which improves the efficiency of marking the hollow of the wall and reduces the risk to workers when marking.

[0025] This application embodiment includes an auxiliary component that allows workers to quickly replace the hollow detection head when it is damaged, ensuring the detection effectiveness of the hollow detection head. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a device for detecting hollow spots in interior walls during building construction.

[0032] Reference Figure 1A device for detecting hollow walls in building construction includes a handle 1, with a telescopic rod 2 coaxially fixedly connected to the upper surface of the handle 1. In this embodiment, the telescopic rod 2 includes an outer rod and an inner rod that slide against each other. A hollow detection head 3 for detection is installed at the end of the telescopic rod 2 away from the handle 1. The height of the hollow detection head 3 can be adjusted by the telescopic rod 2, so that the hollow detection head can be used to detect whether there is a hollow phenomenon on the surface of the wall in the building construction.

[0033] Reference Figure 1 and Figure 2 A marking component 4 is provided on the outer surface of the telescopic rod 2 away from the handle 1. The marking component 4 includes a fixing ring 41 fixedly sleeved on the outer surface of the telescopic rod 2. Two support rods 42 are fixedly connected to the arc surface of the fixing ring 41. The ends of the two support rods 42 away from the fixing ring 41 are fixedly connected to a fixing block 43. A connecting cylinder 44 is fixedly connected to the fixing block 43. A marking pen 45 for marking is slidably connected inside the connecting cylinder 44. A contact pad 441 is fixedly connected to the inner side wall of the connecting cylinder 44. The cross-section of the contact pad 441 is annular. In this embodiment, the contact pad 441 is made of rubber.

[0034] Before testing, the marker pen 45 is inserted into the connecting cylinder 44. At this time, the contact pad 441 wraps around the outer surface of the marker pen 45 under its own elastic force, improving the stability of the marker pen 45 in the connecting cylinder 44. After the marker pen 45 is fixed, the worker taps the wall with the hollow detection head 3. When a hollow phenomenon is detected, the worker rotates the telescopic rod 2 through the handle to make the marker pen 45 face the wall. Then, the marker pen 45 is used to mark the wall. This setting realizes the quick marking of the wall without the need for workers to use tools such as A-frame ladders to mark, which improves the efficiency of hollow detection and marking of the wall, and at the same time reduces the risk of workers marking.

[0035] Reference Figure 1 and Figure 2 The connecting cylinder 44 is provided with a fastening component 5, which includes a threaded ring 51 fixedly connected to the arc surface of the connecting cylinder 44. The threaded ring 51 has a threaded section inside and is connected to the inside of the connecting cylinder 44. A screw 52 is threadedly connected inside the threaded ring 51. A pressing block 53 is fixedly connected to the end of the screw 52 near the marking pen 45, and a gripping block 54 is fixedly connected to the other end. The outer surface of the pressing block 53 is circular to increase the contact area with the marking pen 45. The gripping block 54 has multiple anti-slip grooves 541, which are evenly distributed on the outer surface of the gripping block 54 to increase the friction between the worker's hand and the surface of the gripping block 54.

[0036] After the marking pen 45 is inserted into the connecting cylinder 44, the worker rotates the gripping block 54 to rotate the screw 52. During the rotation of the screw 52, ​​the clamping block 53 moves toward the marking pen 45. When the clamping block 53 presses against the outer surface of the marking pen 45, the worker stops rotating the gripping block 54. The clamping action of the clamping block 53 on the marking pen 45 secures the marking pen 45 in the connecting cylinder 44, preventing the marking pen 45 from coming out of the connecting cylinder 44 during the marking process. At the same time, it prevents the marking from shifting due to vibration during the inspection process, thus ensuring the accuracy of the marking work.

[0037] Reference Figure 1 and Figure 3 The hollow detection head 3 will wear out over time. The worn hollow detection head 3 will affect the detection effect on the walls of the building construction site, which is obviously insufficient.

[0038] Reference Figure 1 and Figure 3 To solve the above technical problems, an auxiliary component 6 is provided on the side of the telescopic rod 2 near the hollow detection head 3. The auxiliary component 6 includes a fixed plate 61 fixedly sleeved on the end of the telescopic rod 2. The fixed plate 61 has a fixed groove 7. The bottom surface of the hollow detection head 3 is fixedly connected to an assembly block 62 that slides with the fixed groove 7. Both the assembly block 62 and the fixed plate 61 have pin holes 71 with the same cross-sectional shape. A plug rod 63 is slidably connected inside the pin hole 71.

[0039] Reference Figure 1 and Figure 3 A spring 64 is fitted on the outer surface of the insertion rod 63. One end of the spring 64 is fixedly connected to the outer surface of the fixing plate 61, and the other end is fixedly connected to the outer surface of the insertion rod 63. In its natural state, the insertion rod 63 passes through the pin hole 71 and penetrates the fixing plate 61 and the assembly block 62. A pull ring 631 is fixedly connected to the end of the insertion rod 63 near the spring 64 to facilitate worker operation. A guide block 632 is integrally formed at the other end. The end face of the guide block 632 is arc-shaped to guide the insertion rod 63 to accurately enter the pin hole 71.

[0040] Reference Figure 1 and Figure 3 Multiple limiting blocks 621 are fixedly connected to the outer surface of the assembly block 62. The inner side wall of the fixing groove 7 is provided with limiting grooves 72 that correspond one-to-one with the multiple limiting blocks 621. When the limiting block 621 is slidably connected inside the corresponding limiting groove 72, the pin hole 71 on the fixing plate 61 is connected to the pin hole 71 of the assembly block 62.

[0041] When the hollow detection head 3 is damaged and needs to be replaced, the worker pulls the insertion rod 63 outward to keep it detached from the assembly block 62 and the fixing plate 61. At this time, the spring 64 is stretched, and then the damaged hollow detection head 3 is removed from the fixing plate 61. After removal, the assembly block 62 on the new hollow detection head 3 is inserted into the fixing groove 7, and the limiting block 621 slides inside the corresponding limiting groove 72. At this time, the pin hole 71 is aligned with the insertion rod 63. Finally, the insertion rod 63 is released, and the spring 64 returns to its original position, causing the insertion rod 63 to pass through the pin hole 71 in the assembly block 62 and the fixing plate 61. The new hollow detection head 3 is now installed. The auxiliary component 6 enables the rapid replacement of the hollow detection head 3 and ensures the detection effect of the hollow detection head 3.

[0042] The implementation principle of the hollow wall detection device for building construction in this embodiment is as follows: Before detection, the marking pen 45 is inserted into the connecting cylinder 44. The worker rotates the grip block 54 to rotate the screw 52. During the rotation of the screw 52, ​​the clamping block 53 moves toward the marking pen 45. When the clamping block 53 is pressed against the outer surface of the marking pen 45, the rotation of the grip block 54 is stopped. After the marking pen 45 is fixed, the worker taps the wall with the hollow detection head 3. When a hollow phenomenon is detected, the worker rotates the telescopic rod 2 through the handle to make the marking pen 45 face the wall. Then, the marking pen 45 is used to mark the wall. This setting realizes the connection between the marking pen 45 and the telescopic rod 2. After a hollow phenomenon is found, the worker does not need to use tools such as a ladder to mark it, which improves the efficiency of hollow detection and marking of the wall, and at the same time reduces the risk of workers marking.
