Description

Technical Field

[0001] This invention relates to the field of hollow surface detection equipment, and in particular to a hollow surface detection machine for building engineering walls. Background Technology

[0002] Hollow areas in walls are a common quality hazard during the quality acceptance and subsequent operation and maintenance of building projects. Because the base layer and decorative layer are not firmly bonded in hollow areas, they are prone to cracking and detachment under temperature changes and external forces. This not only affects the aesthetics of the wall but may also lead to safety accidents. Therefore, detecting hollow areas in walls is a crucial step in ensuring building quality.

[0003] Chinese invention patent CN219245451U discloses a building construction quality inspection device, comprising: a base plate, on which multiple casters are uniformly fixedly connected to the lower surface and a push rod is fixedly connected to the upper surface; an adjustment assembly, fixedly connected to the upper surface of the base plate, the adjustment assembly including a housing, a first motor fixedly connected to the upper surface of the housing, the output end of the first motor slidingly penetrating the housing, a lead screw fixedly connected to the output end of the first motor, and a sliding block threadedly connected to the outer surface of the lead screw; and a detection assembly, fixedly connected to the right outer surface of the adjustment assembly, the detection assembly including a mounting box, with limit rods symmetrically fixedly connected to the inner surface of the housing, both limit rods slidingly penetrating the sliding block, and symmetrically formed grooves on the outer surface of the housing, with sliders slidably connected to the inner surfaces of both grooves. The two sliders are respectively fixedly connected to the sliding block and the mounting box. A triangular support frame is fixedly connected to the outer right surface of each slider. Both triangular support frames are fixedly connected to the mounting box. A second motor is fixedly connected to the lower surface of the mounting box. The output end of the second motor slides through the mounting box. A rotating shaft is fixedly connected to the output end of the second motor. A turntable is fixedly connected to the upper surface of the rotating shaft. A first rotating seat is rotatably connected to the upper surface of the turntable. A connecting arm is fixedly connected to the outer surface of the first rotating seat. A slide rail is fixedly connected to the inner surface of the mounting box. A sliding seat is slidably connected to the outer surface of the slide rail. A second rotating seat is rotatably connected to the upper surface of the sliding seat. The second rotating seat is fixedly connected to the connecting arm. A connecting rod is fixedly connected to the outer surface of the sliding seat. The connecting rod slides through the mounting box. A detection hammer is fixedly connected to the end face of the connecting rod.

[0004] The detection components of the existing device can only be adjusted vertically, and the striking direction of the detection hammer is fixed, making it impossible to adjust the angle in multiple directions. This results in the device being able to detect only a limited area of ​​the vertical wall, making it difficult to cover special locations such as the top of the wall and the ground, thus limiting the detection range of the device. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a wall hollowness detection machine for building engineering.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wall hollow detection machine for building engineering, comprising a movable box, a vertical frame fixed on the top of the movable box, a lifting mechanism provided on the vertical frame, a lifting frame provided on the lifting mechanism, the lifting mechanism being used to drive the lifting frame to rise and fall, a detection mechanism provided on the lifting frame for detecting hollowness on the ground, vertical wall surface and wall top and drilling holes in the hollow wall surface, and a moving mechanism provided on the movable box for driving the movable box to move.

[0007] By adopting the above technical solution, the detection mechanism includes a connecting component, which includes a rotary motor fixed on the lifting frame, a vertical rod fixed on the output end of the rotary motor, a connecting block rotatably installed at the lower end of the vertical rod, an electric rotary table fixed at the lower end of the connecting block, a horizontal plate fixed on the rotating end of the electric rotary table, and a rotary motor fixed on the vertical rod that drives the connecting block to rotate. At the same time, the detection mechanism can perform hollow detection on the ground, vertical wall surface, and wall top, thus expanding the detection range.

[0008] Furthermore, the detection mechanism includes a connecting assembly, which includes a rotary motor fixed to the lifting frame, a vertical rod fixed to the output end of the rotary motor, a connecting block rotatably mounted on the lower end of the vertical rod, an electric rotary table fixed to the lower end of the connecting block, a horizontal plate fixed to the rotating end of the electric rotary table, and a rotary motor fixed to the vertical rod and driving the connecting block to rotate. The detection mechanism also includes a detection assembly for detecting hollow areas in the wall and a drilling assembly for drilling holes in the hollow wall. The detection assembly and the drilling assembly are symmetrically arranged about the middle of the horizontal plate.

[0009] By adopting the above technical solution, when the rotary motor is working, it drives the vertical rod to rotate, which in turn drives the connecting block connected to the vertical rod, the electric rotary table connected to the connecting block, and the detection component and drilling component connected to the horizontal plate to rotate. With the help of the lifting mechanism to adjust the height, the top wall surface can be inspected. When the rotary motor is working, it drives the connecting block, the electric rotary table fixed to the connecting block, the horizontal plate connected to the electric rotary table, and the detection component and drilling component connected to the horizontal plate to rotate, allowing for the detection of hollow areas on the bottom wall surface, inclined wall surface, and vertical wall surface, thus expanding the applicability of the device. Furthermore, when a hollow area is detected, simply operating the electric rotary table to rotate the horizontal plate 180 degrees will rotate the drilling component to the position of the hollow wall surface, without needing to move the entire device, making the device easy to use.

[0010] Furthermore, the detection assembly includes a mounting shell fixed to an electric rotary table, a lifting motor fixed to the mounting shell, and a detection rod that penetrates the bottom wall of the mounting shell and slides in cooperation with the mounting shell. The output end of the lifting motor penetrates the side wall of the mounting shell and is rotatably connected to the mounting shell. The detection rod penetrates the top of the electric rotary table and slides in cooperation with the electric rotary table. The detection assembly also includes a lifting block fixed to the output end of the lifting motor and coaxially arranged with the output end of the lifting motor, an adjusting column rotatably mounted on the detection rod, and a first ball bearing movably mounted on the lower end of the detection rod. The lifting block has a lifting groove eccentrically arranged with the lifting block, and the adjusting column slides in cooperation with the lifting groove.

[0011] By adopting the above technical solution, when the lifting motor is working, it drives the lifting block to rotate. Since the lifting groove and the lifting block are eccentrically set, the adjusting column that slides with the lifting groove, the detection rod connected to the adjusting column, and the first ball that is movably connected to the detection rod can all move up and down. The first ball contacts the wall and produces a sound, so that the staff can judge the hollowness of the wall.

[0012] Furthermore, the electric rotary table has an L-shaped structure, and the drilling assembly includes two slide rails fixedly installed on the vertical section of the electric rotary table, a protective shell slidably installed on the vertical section of the electric rotary table, a worm gear passing through the bottom of the protective shell and rotatably connected to the protective shell, a drill rod detachably connected to the lower end of the worm gear and coaxially arranged with the worm gear, and a drilling motor fixed to the top of the protective shell and driving the worm gear to rotate. The slide rails pass through the top and bottom of the protective shell and slide in cooperation with the protective shell. The detection mechanism also includes a displacement component for driving the protective shell to move.

[0013] By adopting the above technical solution, the drilling motor drives the worm gear to rotate, which in turn drives the drill rod connected to the worm gear to rotate. At the same time, the displacement component drives the protective shell to move, which in turn drives the worm gear connected to the protective shell and the drill rod connected to the worm gear to move. As the drill rod rotates, it moves closer to or away from the wall, thus enabling drilling operations on the wall.

[0014] Furthermore, the displacement assembly includes a displacement rack fixed on the slide rail, the displacement rack passing through the top and bottom of the protective shell and slidingly engaging with the protective shell. The displacement assembly also includes a drive rod rotatably installed inside the protective shell, a worm wheel fixedly sleeved on the drive rod and meshing with a worm gear, and a displacement gear fixedly sleeved on the drive rod and meshing with the displacement rack. The number of displacement gears, the number of displacement racks, and the number of slide rails are all equal and their positions correspond one-to-one.

[0015] By adopting the above technical solution, when the worm rotates, it drives the worm wheel meshing with the worm, the drive rod fixed to the worm wheel, and the displacement gear fixed to the drive rod to rotate. Since the displacement gear meshes with the displacement rack, the operation of moving the protective shell is realized.

[0016] Furthermore, the vertical frame has a hollow structure with an open top, and the internal cross-section of the vertical frame is rectangular. The lifting mechanism includes a first lifting component, which includes a lifting frame slidably mounted on the vertical frame, a dual-output motor fixed to the top wall of the movable box, a rectangular column fixed to the top wall of the lifting frame and inserted into the vertical frame, and a threaded column rotatably mounted on the bottom wall of the vertical frame. The top wall of the rectangular column is provided with a threaded groove extending to the bottom of the rectangular column. The threaded column is threadedly connected to the threaded groove. One output end of the dual-output motor is used to drive the threaded column to rotate. The lifting frame is slidably mounted on the lifting frame. The lifting mechanism also includes a second lifting component for driving the lifting frame to rise and fall while simultaneously driving the lifting frame to rise and fall along the lifting frame.

[0017] By adopting the above technical solution, when the dual-output motor is working, it drives the threaded column to rotate, which in turn drives the rectangular column threadedly connected to the threaded column, the lifting frame fixed to the rectangular column, and the lifting frame connected to the lifting frame to rise or fall, thereby realizing the adjustment of the height of the detection component and the drilling component.

[0018] Furthermore, the second lifting assembly includes a first coupling shaft rotatably mounted on the lifting frame, a second coupling shaft passing through the side wall of the lifting frame and rotatably connected to the lifting frame, two sprockets respectively fixedly sleeved on the first coupling shaft and the second coupling shaft, and a chain meshing with both sprockets. The lifting frame is fixed to the belt body of the chain near the side of the lifting frame. The lifting mechanism also includes a drive assembly for driving the second coupling shaft to rotate.

[0019] By adopting the above technical solution, the operation drive component drives the second coupling shaft to rotate. With the cooperation of the two sprockets and the first coupling shaft, the sprocket fixed to the second coupling shaft is driven to rotate, thereby driving the lifting frame to rise and fall along the lifting frame, thus expanding the detection range of the device.

[0020] Furthermore, a through hole is provided through the side wall of the vertical frame, and the driving assembly includes a driving gear fixedly sleeved on the second coupling and located in the through hole, a driving rack fixed on the inner side wall of the through hole and meshing with the driving gear, and a limiting rod fixed on the lifting frame and slidingly cooperating with the lifting frame.

[0021] By adopting the above technical solution, when the lifting frame is raised or lowered, the first connecting shaft connected to the lifting frame, the second connecting shaft connected to the lifting frame, and the drive gear fixed to the second connecting shaft are all raised or lowered. Since the drive gear meshes with the drive rack, the drive gear and the second connecting shaft fixed to the drive gear can all rotate, thereby ensuring the normal lifting and lowering operation of the lifting frame.

[0022] Furthermore, the moving mechanism is provided with four sets arranged in a rectangular array around the moving box. The moving mechanism includes a rotating shell that passes through the bottom of the moving box and is rotatably connected to the moving box, a moving wheel that is rotatably installed in the rotating shell, a driven gear that is fixedly sleeved on the rotating shell, a moving motor that is fixedly sleeved on the rotating shell and drives the moving wheel to rotate, and a driving gear that is fixedly sleeved on the other output end of the dual-output motor and meshes with the four driven gears.

[0023] By adopting the above technical solution, when the mobile motor is working, it drives the mobile wheel to rotate, thereby realizing the movement of the entire device. In addition, by operating the other output end of the dual-output motor and driving the drive gear to rotate, the driven gear meshing with the drive gear, the rotating shell fixed with the driven gear, and the mobile wheel connected to the rotating shell can all rotate, thereby adjusting the direction of rotation of the mobile wheel and thus adjusting the overall movement direction.

[0024] Furthermore, an auxiliary rod is fixed to the bottom of the electric rotary table, a second ball bearing is movably mounted on the bottom of the auxiliary rod, a pressure sensor is provided on the auxiliary rod, and an indicator light connected to the pressure sensor circuit is fixed on the movable box. The bottom of the second ball bearing is flush with the bottom of the movable wheel.

[0025] By adopting the above technical solution, the entire moving device is moved until the second ball is in contact with the wall. The pressure sensor will detect the pressure felt by the second ball until the rated pressure is reached. The indicator light will then illuminate, which will remind the staff that the device has reached the detection position. There is no need to adjust the distance between the first ball and the wall in advance, which makes the device easier to use.

[0026] In summary, the present invention has the following beneficial effects: In this application, by improving the prior art, it is possible to detect hollow areas on the ground, vertical walls and the top of the wall, thus expanding the scope of application. In addition, it eliminates the need for additional drilling equipment required by the prior art, making it easier for staff to use. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-8As shown in the illustration, this application discloses a wall hollowness detection machine for building engineering, including a movable box 1, a lifting groove 5, a lifting mechanism 6, and a moving mechanism 8. A vertical frame 2 is fixed to the top of the movable box 1. The vertical frame 2 has a hollow structure with an open top, and the internal cross-section of the vertical frame 2 is rectangular. A through hole 7 is provided through the side wall of the vertical frame 2, and a lifting frame 3 is provided on the lifting mechanism 6. First, the moving mechanism 8 is operated to drive the movable box 1 to move and move the device to the wall to be tested. Then, the lifting mechanism 6 is operated to drive the lifting frame 3 to rise and fall, while the detection mechanism 4 is operated to detect hollowness in the wall. If hollowness is found, the detection mechanism 4 can be operated to drill holes in the hollow wall. This allows the device to detect hollowness while drilling holes are being drilled, eliminating the need for additional drilling equipment as in the prior art, making it easier for workers to use. At the same time, the detection mechanism 4 can detect hollowness on the ground, vertical walls, and the top of the wall, expanding the detection range.

[0031] The detection mechanism 4 is mounted on the lifting frame 3. It is used to detect hollow areas on the ground, vertical walls, and wall tops, and to drill holes in hollow walls. The detection mechanism 4 includes a connecting assembly 41, a detection assembly 42, a drilling assembly 43, and a displacement assembly 44. The connecting assembly 41 includes a rotary motor 411, a vertical rod 412, a connecting block 413, an electric rotary table 414, a horizontal plate 415, and a rotating motor 416. The rotary motor 411 is fixed to the lifting frame 3, and the vertical rod 412 is fixed to the output end of the rotary motor 411. The connecting block 413 is rotatably mounted on the lower end of the vertical rod 412, and the electric rotary table 414 is fixed to the lower end of the connecting block 413. The electric rotary table 414 has an L-shaped structure. The horizontal plate 415 is fixed to the rotating end of the electric rotary table 414, and the rotating motor 416 is fixed to the vertical rod 412 and drives the connecting block 413 to rotate. When the rotary motor 411 operates, it drives the vertical rod 412 to rotate, which in turn drives the connecting block 413 connected to the vertical rod 412, the electric rotary table 414 connected to the connecting block 413, and the detection component 42 and drilling component 43 connected to the horizontal plate 415 to rotate. Combined with the lifting mechanism 6 to adjust the height, this allows for the detection of the top wall surface. When the rotary motor 416 operates, it drives the connecting block 413, the electric rotary table 414 fixed to the connecting block 413, the horizontal plate 415 connected to the electric rotary table 414, and the detection component 42 and drilling component 43 connected to the horizontal plate 415 to rotate, allowing for the detection of hollow areas on the bottom wall surface, inclined wall surface, and vertical wall surface, thus expanding the applicability of the device. Furthermore, when a hollow area is detected, simply operating the electric rotary table 414 to rotate the horizontal plate 415 180 degrees will rotate the drilling component 43 to the position of the hollow wall surface, without needing to move the entire device, making the device easy to use.

[0032] The detection assembly 42 and the drilling assembly 43 are symmetrically arranged about the middle of the horizontal plate 415. The detection assembly 42 is used to detect hollow areas in the wall surface. The detection assembly 42 includes a mounting shell 421, a lifting motor 422, a detection rod 423, a lifting block 424, an adjusting column 425, and a first ball bearing 426. The mounting shell 421 is fixed to the electric rotary table 414. The lifting motor 422 is fixed to the mounting shell 421, and its output end passes through the side wall of the mounting shell 421 and is rotatably connected to the mounting shell 421. The detection rod 423 passes through the inner bottom wall of the mounting shell 421 and slides in cooperation with the mounting shell 421. The detection rod 423 passes through the top of the electric rotary table 414 and slides in cooperation with the electric rotary table 414. The lifting block 424 is fixed to the output end of the lifting motor 422 and is coaxially arranged with the output end of the lifting motor 422. The lifting block 424 has a lifting groove 5 that is eccentrically arranged with respect to the lifting block 424. An adjusting column 425 is rotatably mounted on a detection rod 423. The adjusting column 425 is slidably engaged with a lifting groove 5. A first ball bearing 426 is movably mounted on the lower end of the detection rod 423. When the lifting motor 422 is working, it drives the lifting block 424 to rotate. Due to the eccentric arrangement of the lifting groove 5 and the lifting block 424, the adjusting column 425, which is slidably engaged with the lifting groove 5, the detection rod 423 connected to the adjusting column 425, and the first ball bearing 426, which is movably connected to the detection rod 423, all move up and down. The first ball bearing 426 contacts the wall surface and produces a sound, allowing staff to determine the hollowness of the wall surface.

[0033] The drilling assembly 43 is used to drill holes in hollow walls. The drilling assembly 43 includes a slide rail 431, a protective shell 432, a worm gear 433, a drill rod 434, and a drilling motor 435. Two slide rails 431 are provided, both fixedly installed on the vertical section of the electric rotary table 414. The slide rails 431 pass through the top and bottom of the protective shell 432 and slide in cooperation with it. The protective shell 432 is slidably mounted on the vertical section of the electric rotary table 414. The worm gear 433 passes through the bottom of the protective shell 432 and is rotatably connected to it. The drill rod 434 is detachably connected to the lower end of the worm gear 433 and is coaxially mounted with the worm gear 433. The drilling motor 435 is fixed to the top of the protective shell 432 and drives the worm gear 433 to rotate. The drilling motor 435 drives the worm gear 433 to rotate, which in turn drives the drill rod 434 connected to the worm gear 433 to rotate. At the same time, the displacement component 44 drives the protective shell 432 to move, which in turn drives the worm gear 433 connected to the protective shell 432 and the drill rod 434 connected to the worm gear 433 to move. As the drill rod 434 rotates, it moves closer to or away from the wall, thus enabling drilling operations on the wall.

[0034] The displacement assembly 44 is used to drive the protective shell 432 to move. The displacement assembly 44 includes a displacement rack 441, a drive rod 442, a worm gear 443, and a displacement gear 444. The displacement rack 441 is fixed on the slide rail 431, and passes through the top and bottom of the protective shell 432 and slides in engagement with the protective shell 432. The drive rod 442 is rotatably mounted inside the protective shell 432, and the worm gear 443 is fixedly sleeved on the drive rod 442 and meshes with the worm 433. The displacement gear 444 is fixedly sleeved on the drive rod 442 and meshes with the displacement rack 441. The number of displacement gears 444, the number of displacement racks 441, and the number of slide rails 431 are all equal and their positions correspond one-to-one. When the worm 433 rotates, it drives the worm wheel 443 meshing with the worm 433, the drive rod 442 fixed to the worm wheel 443, and the displacement gear 444 fixed to the drive rod 442 to rotate. Since the displacement gear 444 meshes with the displacement rack 441, the operation of moving the protective shell 432 is realized.

[0035] A lifting mechanism 6 is mounted on the vertical frame 2 and is used to drive the lifting frame 3 to rise and fall. The lifting mechanism 6 includes a first lifting assembly 61, a second lifting assembly 62, and a drive assembly 63. The first lifting assembly 61 includes a lifting frame 611, a dual-output motor 612, a rectangular column 613, and a threaded column 614. The lifting frame 611 is slidably mounted on the vertical frame 2, and the lifting frame 3 is slidably mounted on the lifting frame 611. The dual-output motor 612 is fixed to the inner top wall of the movable box 1, and one output end of the dual-output motor 612 is used to drive the threaded column 614 to rotate. The rectangular column 613 is fixed to the inner top wall of the lifting frame 611 and inserted into the vertical frame 2. A threaded groove extending to the bottom of the rectangular column 613 is provided through the top wall of the rectangular column 613. The threaded column 614 is rotatably mounted on the inner bottom wall of the vertical frame 2, and the threaded column 614 is threadedly connected to the threaded groove. When the dual-output motor 612 is working, it drives the threaded column 614 to rotate, which in turn drives the rectangular column 613 threadedly connected to the threaded column 614, the lifting frame 611 fixed to the rectangular column 613, and the lifting frame 3 connected to the lifting frame 611 to rise or fall, thereby realizing the adjustment of the height of the detection component 42 and the drilling component 43.

[0036] The second lifting assembly 62 is used to drive the lifting frame 611 to rise and fall simultaneously, and also to drive the lifting frame 3 to rise and fall along the lifting frame 611. The second lifting assembly 62 includes a first coupling 621, a second coupling 622, a sprocket 623, and a chain 624. The first coupling 621 is rotatably mounted on the lifting frame 611, and the second coupling 622 passes through the side wall of the lifting frame 611 and is rotatably connected to the lifting frame 611. There are two sprockets 623, which are respectively fixedly sleeved on the first coupling 621 and the second coupling 622. The chain 624 meshes with both sprockets 623, and the lifting frame 3 is fixed to the belt body of the chain 624 near the side of the lifting frame 3. The operation drive component 63 drives the second coupling shaft 622 to rotate. With the cooperation of the two sprockets 623 and the first coupling shaft 621, the sprocket 623 fixed to the second coupling shaft 622 is driven to rotate, thereby driving the lifting frame 3 to rise and fall along the lifting frame 611, thereby expanding the detection range of the device.

[0037] The drive assembly 63 is used to drive the second coupling 622 to rotate. The drive assembly 63 includes a drive gear 631, a drive rack 632, and a limiting rod 633. The drive gear 631 is fixedly sleeved on the second coupling 622 and located in the through hole 7. The drive rack 632 is fixed on the inner side wall of the through hole 7 and meshes with the drive gear 631. The limiting rod 633 is fixed on the lifting frame 611 and slides in cooperation with the lifting frame 3. When the lifting frame 611 is raised or lowered, it drives the first coupling 621 connected to the lifting frame 611, the second coupling 622 connected to the lifting frame 611, and the drive gear 631 fixed to the second coupling 622 to all rise or fall. Since the drive gear 631 meshes with the drive rack 632, both the drive gear 631 and the second coupling 622 fixed to the drive gear 631 can rotate, thereby ensuring the normal raising and lowering operation of the lifting frame 3.

[0038] A moving mechanism 8 is mounted on the moving box 1 and is used to drive the moving box 1 to move. Four sets of moving mechanisms 8 are arranged in a rectangular array around the moving box 1. Each moving mechanism 8 includes a rotating shell 81, moving wheels 82, driven gears 83, a moving motor 84, and a driving gear 85. The rotating shell 81 extends through the bottom of the moving box 1 and is rotatably connected to it. The moving wheels 82 are rotatably mounted inside the rotating shell 81. The driven gears 83 are fixedly mounted on the rotating shell 81. The moving motor 84 is fixedly mounted on the rotating shell 81 and drives the moving wheels 82 to rotate. The driving gears 85 are fixedly mounted on the other output end of the dual-output motor 612 and mesh with all four driven gears 83. When the mobile motor 84 is working, it drives the mobile wheel 82 to rotate, thereby enabling the overall movement of the device. In addition, operating the other output end of the dual-output motor 612 and driving the drive gear 85 to rotate will drive the driven gear 83 meshing with the drive gear 85, the rotating housing 81 fixed to the driven gear 83, and the mobile wheel 82 connected to the rotating housing 81 to rotate, thereby adjusting the direction of rotation of the mobile wheel 82 and thus adjusting the overall movement direction.

[0039] An auxiliary rod 9 is fixed to the bottom of the electric rotary table 414. A second ball bearing 10 is movably mounted on the bottom of the auxiliary rod 9. A pressure sensor is installed on the auxiliary rod 9. An indicator light connected to the pressure sensor circuit is fixed on the movable box 1. The bottom of the second ball bearing 10 is flush with the bottom of the movable wheel 82.

[0040] By adopting the above technical solution, the entire moving device is moved until the second ball bearing 10 is in contact with the wall. The pressure sensor will detect the pressure felt by the second ball bearing 10.
