Description

Technical Field

[0001] This application relates to the field of building engineering testing, and in particular to a multifunctional testing device for building supervision. Background Technology

[0002] Construction project supervision refers to the professional management service activities of qualified construction supervision companies that, upon the entrustment of the construction unit (i.e., the project owner), undertake part of the project management work and control the construction activities of the contractor on behalf of the construction unit. During the construction process, construction supervision requires the inspection and monitoring of building quality, especially during the project acceptance stage. During acceptance, it is necessary to inspect various wall surfaces for hollowness, flatness, and verticality.

[0003] Currently, most existing methods for detecting hollow walls use a hollow hammer. The inspector holds the hammer and taps the wall, judging the hollowness by the sound produced. If the sound is heavy, the wall is solid; if the sound is crisp and echoing, the wall is mostly hollow and therefore unqualified.

[0004] Regarding the aforementioned technologies, the inventors discovered that when detecting hollow spots in a wall, the wall needs to be tapped point by point. The distance between two adjacent tapping points is controlled manually, which inevitably leads to an excessive distance between two adjacent tapping points. This makes it difficult to detect the wall between the two tapping points in a timely manner, resulting in the defect that hollow spots in the wall are easily missed. Summary of the Invention

[0005] To alleviate the problem of missed detections in wall hollowness testing, this application provides a multi-functional testing device for building supervision.

[0006] This application provides a multi-functional testing device for building supervision, which adopts the following technical solution:

[0007] A multifunctional testing device for building supervision includes a movable frame, a grip, a striking component, and a drive mechanism. The movable frame includes a movable plate and multiple movable wheels, all of which are mounted on the movable plate. The grip is connected to the movable plate. The drive mechanism includes a drive motor, a cam, a sliding rod, and a spring. The drive motor is fixedly connected to the movable plate, the cam is rotatably connected to the movable plate, and the drive motor is drively connected to the cam. The sliding rod is slidably connected to the movable plate, and the cam is used to push the sliding rod to slide. The striking component is connected to the sliding rod, and the spring is disposed between the sliding rod and the movable plate, and the spring is used to pull the sliding rod back.

[0008] By adopting the above technical solution, in use, the moving wheel is first attached to the wall, then the drive motor is started, and the drive motor drives the cam to rotate. The rotation of the cam pushes the sliding rod to move. With the cooperation of the spring, the sliding rod can be moved back and forth, so that the striking part set on the sliding rod can move back and forth with the sliding rod, thereby making the striking part strike the wall. Then, the inspector pushes the moving plate to move on the wall to achieve a comprehensive inspection of the wall, reducing the possibility of omissions when conducting hollow wall inspection and improving the comprehensiveness of the hollow wall inspection.

[0009] Preferably, the striking element is a rotating wheel, which is rotatably connected to the sliding rod. A transmission mechanism is provided on the moving plate, and the rotating wheel and the cam are connected by transmission mechanism. A distance sensor, a controller, and a stabilizing element are provided on the moving plate. The distance sensor is electrically connected to the controller and is used to detect the change in distance between itself and the side wall of the cam in real time. The stabilizing element is used to lock the sliding rod.

[0010] By adopting the above technical solution, the striking element is set as a rotating wheel, and the sliding rod is locked with a stabilizing component to make the rotating wheel and the moving wheel flush. Then, the moving frame is placed on the wall, and the inspector pushes the moving frame to move. The rotating wheel rotates under the action of friction between itself and the wall. The rotation of the rotating wheel will drive the cam to rotate through the transmission mechanism. At this time, the distance between the distance sensor and the side wall of the cam changes in real time. When the wall is uneven, a gap will appear between the rotating wheel and the wall, and the rotating wheel will stop rotating. The rotation of the rotating wheel will stop driving the cam at the same time, so that the cam will stop rotating at the same time. Thus, the distance sensor will no longer detect the distance between itself and the side wall of the cam. At this time, the distance sensor will transmit an electrical signal to the controller, and the controller will sound an alarm, so that the location of the uneven wall can be known, and the flatness of the wall can be detected.

[0011] Preferably, the transmission mechanism includes a connecting rod, a first transmission rod, a second transmission rod, a second bevel gear, a third bevel gear, and two first bevel gears. The connecting rod is rotatably connected to the movable plate and is connected to the cam drive. One of the first bevel gears is coaxially fixedly connected to the connecting rod, and the other first bevel gear is coaxially fixedly connected to the rotating wheel. The first transmission rod is rotatably connected to the movable plate, and the second transmission rod is slidably connected to the first transmission rod. The second transmission rod is rotatably connected to the sliding rod, and the second bevel gear is coaxially fixedly connected to the first transmission rod. The second bevel gear is coaxially fixedly connected to the first bevel gear coaxially fixedly connected to the connecting rod, and the third bevel gear is coaxially fixedly connected to the first bevel gear coaxially fixedly connected to the rotating wheel.

[0012] By adopting the above technical solution, the first transmission rod and the second transmission rod are slidably connected. When detecting hollowness on the wall surface, the slidable connection of the first and second transmission rods ensures the reciprocating sliding of the sliding rod. When detecting the flatness of the wall surface, the rotation of the rotating rod will drive the first bevel gear, which is fixedly connected to it on the same axis, to rotate. This, in turn, drives the third bevel gear, which is meshed with it. Under the transmission action of the first and second transmission rods, the second bevel gear is driven. Then, through the cooperation of the second bevel gear and another first bevel gear, the cam is driven, ensuring the smooth progress of the wall surface flatness detection.

[0013] Preferably, the cam is rotatably connected to the movable plate via a rotating rod, the rotating rod is fixedly connected to the cam, the rotating rod is rotatably connected to the movable plate, a connecting rod passes through one end of the rotating rod, and the main shaft of the drive motor passes through the other end of the rotating rod. A first bolt and a second bolt are threaded onto the rotating rod, the first bolt is used to abut against the connecting rod, and the second bolt is used to abut against the main shaft of the drive motor.

[0014] By adopting the above technical solution, the shafts of the connecting rod and the drive motor are respectively threaded through the two ends of the rotating rod. When detecting wall hollowness, tightening the second bolt to press the main shaft of the drive motor and loosening the first bolt will cause the drive motor to drive the cam to rotate. When detecting wall flatness, tightening the first bolt to press the connecting rod and loosening the second bolt will cause the rotating wheel to drive the cam to rotate through the transmission of the connecting rod, thereby realizing the detection of wall flatness. At the same time, the rotating rod is separated from the main shaft of the drive motor to avoid the drive motor from obstructing the rotation of the rotating rod.

[0015] Preferably, the movable plate is provided with a vertical detection mechanism, which includes a winding roller, a hanging line, and a hanging hammer. The winding roller is rotatably connected to the movable plate, the drive motor is drivenly connected to the winding roller, the hanging line is wound on the winding roller, and the hanging hammer is fixedly connected to the hanging line.

[0016] By adopting the above technical solution, the drive motor is connected to the winding roller, the moving plate is moved to a higher position on the wall, and then the drive motor drives the winding roller to rotate, which allows the hanging line on the winding roller to be lowered, so that the plumb bob hangs down naturally. Then, by measuring the distance between the plumb bob and the wall, the verticality of the wall can be detected. This allows the detection device to detect wall hollowness and wall flatness at the same time as wall verticality, thus improving the functionality of the detection device.

[0017] Preferably, the winding roller is sleeved on the outside of the drive motor spindle, and a third bolt is threaded onto the winding roller, the third bolt being used to abut against the drive motor spindle.

[0018] By adopting the above technical solution, the winding roller is sleeved on the outside of the drive motor main shaft. When the second bolt is tightened to detect hollowness on the wall, the third bolt is in a loose state. When the verticality of the wall is detected, the third bolt is tightened so that it presses against the main shaft of the drive motor. The second bolt is then loosened, which allows the drive motor to drive the winding roller to rotate, thereby detecting the verticality of the wall. By adjusting the drive motor to connect different rotating parts, different functions of detection can be achieved.

[0019] Preferably, the hammer has a threaded hole, and a guide tube for guiding the hanging line is fixedly connected to the moving plate. The guide tube has a thread that matches the threaded hole.

[0020] By adopting the above technical solution, the guide tube is used to guide the lowering of the hanging line, ensuring the fixation of the lower position of the guide tube. This ensures that the testing personnel know the distance between the upper end of the hanging line and the wall, facilitating the calculation of the wall's verticality. At the same time, the threaded hole and the thread on the guide tube are used to fix the plumb bob, improving the stability of the plumb bob when it is not in use.

[0021] Preferably, the stabilizing member is a screw, which passes through the movable plate and is threadedly connected to the movable plate. The screw is used to press the sliding rod against the plate.

[0022] By adopting the above technical solution, when performing wall flatness testing, rotating the screw will cause the screw to press against the sliding rod and push the rotating wheel to move to a position flush with multiple moving wheels, thus ensuring the stability of the rotating wheel when performing wall flatness testing.

[0023] Preferably, the gripping member includes a top support rod, a gripping rod, and a locking member. The top support rod is hinged to the movable plate, the gripping rod passes through the end of the top support rod away from the gripping rod, the gripping rod is slidably connected to the top support rod, and the locking member is connected to the top support rod to lock the gripping rod.

[0024] By adopting the above technical solution, the hinge of the top support rod facilitates the movement of the mobile frame, while the sliding grip rod can increase the pushing distance of the mobile frame, making it convenient to detect higher parts of the wall. When not in use, the grip rod can be slid into the top support rod for easy storage of the detection device.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] 1. By setting the striking element on the sliding rod, the drive motor drives the cam to rotate. The rotation of the cam pushes the sliding rod to move. With the cooperation of the spring, the sliding rod can be moved back and forth, so that the striking element set on the sliding rod can move back and forth with the sliding rod. This allows the striking element to strike the wall surface. Then, the inspector pushes the moving plate on the wall to achieve a comprehensive inspection of the wall surface, reducing the possibility of omissions when conducting hollow sound inspection.

[0027] 2. By setting the striking element as a rotating wheel and using a stabilizing element to lock the sliding rod, the rotating wheel and the moving wheel are made to be flush. Then, the moving frame is placed on the wall, and the inspector pushes the moving frame to move. The rotating wheel rotates under the action of friction between it and the wall. The rotation of the rotating wheel will drive the cam to rotate through the transmission mechanism. At this time, the distance between the distance sensor and the side wall of the cam changes in real time. By detecting the rotation of the cam in real time, the location of the uneven wall can be known, and the flatness of the wall can be detected.

[0028] 3. By placing the winding roller on the outside of the drive motor spindle and tightening the third bolt to press against the drive motor spindle, and loosening the second bolt, the drive motor can drive the winding roller to rotate, thereby detecting the verticality of the wall. By adjusting different connection methods, the detection device can perform multi-functional measurements. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a multifunctional testing device for building supervision.

[0039] Reference Figure 1 and Figure 2 A multifunctional inspection device for building supervision includes a movable frame 100, on which a grip 200 is mounted, allowing inspectors to move the frame by holding the grip 200. A striking component 300 is slidably connected to the movable frame 100 for striking the wall. A drive mechanism 400 is mounted on the movable frame 100 to drive the striking component 300 to reciprocate.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The movable frame 100 includes a movable plate 110, on which four movable wheels 120 are rotatably connected. The four movable wheels 120 are located at the four corners of the movable plate 110, and the gripping member 200 is installed on the movable plate 110.

[0041] The drive mechanism 400 includes a support frame 410, which is fixedly connected to one side of the four moving wheels 120 near the moving plate 110. A sliding rod 420 is mounted on the support frame 410, which is perpendicular to the moving plate 110 and slidably connected to the support frame 410. A striking element 300 is mounted on the side of the sliding rod 420 away from the moving plate 110. A push plate 430 is fixedly connected to the side of the sliding rod 420 away from the moving plate 110. A spring 440 is sleeved on the outer side of the sliding rod 420. One end of the spring 440 is fixedly connected to the push plate 430, and the other end of the spring 440 is fixedly connected to the support frame 410.

[0042] A cam 450 is rotatably connected to one side of the movable plate 110 near the push plate 430. The rotation axis of the cam 450 is perpendicular to the length direction of the sliding rod 420. A drive motor 460 is fixedly connected to the movable plate 110, and the main shaft of the drive motor 460 is connected to the cam 450 for transmission. When detecting hollow spots on the wall, the movable frame 100 is placed on the wall, and the movable frame 100 is moved by the grip 200. At the same time, the drive motor 460 is started, and the rotation of the main shaft of the drive motor 460 drives the cam 450 to rotate. Then, the cam 450 pushes the sliding rod 420 to move closer to the wall. Then, the sliding rod 420 pushes the tapping part 300 to move, realizing repeated tapping on the wall, thereby realizing the detection of hollow spots on the wall, reducing the possibility of omissions during the detection of hollow spots, and ensuring the comprehensiveness of the building supervision inspection.

[0043] Reference Figure 2 and Figure 3 The striking element 300 is a rotating wheel 310, which is rotatably connected to the sliding rod 420. The rotation axis of the rotating wheel 310 is parallel to the rotation axis of the moving wheel 120. A transmission mechanism 600 is installed on the moving plate 110, and the rotating wheel 310 is connected to the cam 450 through the transmission mechanism 600.

[0044] A rotating rod 451 is coaxially fixedly connected to a cam 450. The cam 450 is rotatably connected to a movable plate 110 via the rotating rod 451. The main shaft of the drive motor 460 is detachably and coaxially fixedly connected to the rotating rod 451. A distance sensor 500 is fixedly connected to the movable plate 110. The distance sensor 500 is located around the cam 450 and detects the distance between itself and the side wall of the cam 450 in real time. A controller 510 is fixedly connected to the movable plate 110, and the distance sensor 500 is electrically connected to the controller 510. A stabilizing member 520 is installed on the movable plate 110, which is used to push and lock the push plate 430. By setting the striking element 300 as a rotating wheel 310 and locking the push plate 430 with the stabilizing element 520, the rotating wheel 310 is made to abut against the wall and remain stable. When the moving plate 110 is pushed to move and detect the flatness of the wall, the rotating wheel 310 will rotate under the action of friction, and then drive the cam 450 to rotate through the transmission mechanism 600. At this time, the distance between the distance sensor 500 and the side wall of the cam 450 changes in real time. When encountering unevenness in the wall, a gap will appear between the rotating wheel 310 and the wall, which will cause the rotating wheel 310 to stop rotating. When the rotating wheel 310 stops, it will also stop driving the cam 450, causing the cam 450 to stop rotating at the same time. Thus, the distance sensor 500 will detect that the distance between the distance sensor 500 and the side wall of the cam 450 no longer changes in real time. At this time, the distance sensor 500 will transmit an electrical signal to the controller 510, and the controller 510 will issue an alarm, so that the location of the unevenness in the wall can be known, and the flatness of the wall can be detected.

[0045] Reference Figure 3 and Figure 4The transmission mechanism 600 includes a connecting rod 610 rotatably connected to the side of the movable plate 110 near the cam 450. The connecting rod 610 is detachably coaxially fixedly connected to the rotating rod 451. A first bevel gear 620 is coaxially fixedly connected to the connecting rod 610, and another first bevel gear 620 is fixedly connected to the rotating wheel 310. A first transmission rod 630 is rotatably connected to the side of the movable plate 110 near the cam 450. The rotation axis of the first transmission rod 630 is perpendicular to the movable plate 110. A second bevel gear 650 is coaxially fixedly connected to the first transmission rod 630. A first bevel gear 620 fixedly connected to the connecting rod 610 meshes with the second bevel gear 650. A second transmission rod 640 is coaxially passed through the end of the first transmission rod 630 away from the movable plate 110. A second rotating rod 451 is slidably connected to the first transmission rod 630. The second transmission rod 640 is rotatably connected to the sliding rod 420. A third bevel gear 660 is coaxially fixedly connected to the first transmission rod 630. The third bevel gear 660 meshes with the first bevel gear 620 rotatably connected to the rotating wheel 310. When the rotating wheel 310 rotates, it drives the first bevel gear 620, which is fixedly connected to it on the same axis, to rotate. Then, through the cooperation of the second bevel gear 650, it drives the first transmission rod 630 and the second transmission rod 640 to rotate. Thus, through the cooperation of the second bevel gear 650 and the other first bevel gear 620, the connecting rod 610 is driven. Since the connecting rod 610 is fixedly connected to the transmission rod on the same axis, it can drive the cam 450 to rotate. At the same time, by utilizing the sliding connection of the first transmission rod 630 and the second transmission rod 640, the rotating wheel 310 can be repeatedly tapped on the wall surface when detecting hollowness in the wall surface.

[0046] Reference Figure 3 , Figure 4 and Figure 5A connecting rod 610 passes through one end of the rotating rod 451, and the connecting rod 610 slides relative to the rotating rod 451. The main shaft of the drive motor 460 passes through the other end of the rotating rod 451, and the main shaft of the drive motor 460 slides relative to the connecting rod 610. A first bolt 670 and a second bolt 680 pass through the outer side of the rotating rod 451. Both the first bolt 670 and the second bolt 680 are threadedly connected to the rotating rod 451. The first bolt 670 is located at the end of the rotating rod 451 near the connecting rod 610, and the first bolt 670 is used to tighten the rotating rod 451. The second bolt 680 is located at the end of the rotating rod 451 near the drive motor 460, and the second bolt 680 is used to tighten the main shaft of the drive motor 460. When using the detection device to detect hollow areas, tightening the second bolt 680 secures the main shaft of the drive motor 460, thus fixing the drive motor 460 main shaft to the rotating rod 451. Then, starting the drive motor 460 causes the cam 450 to rotate, thereby detecting hollow areas on the wall. When detecting wall flatness, loosening the second bolt 680 and tightening the first bolt 670 secures the connecting rod 610, thus fixing the connecting rod 610 to the rotating rod 451. Then, starting the controller 510 and the distance sensor 500 pushes the moving plate 110 to move on the wall, thereby detecting the flatness of the wall.

[0047] Reference Figure 3 The stabilizing component 520 includes a screw 521 that passes through the movable plate 110. The axis of the screw 521 is perpendicular to the movable plate 110, and the screw 521 is threadedly connected to the movable plate 110. When performing wall flatness testing, rotating the screw 521 will push the push plate 430 to move, making the bottom of the rotating wheel 310 flush with the bottom of the movable wheel 120 and maintaining stability, thus ensuring stability during wall flatness testing.

[0048] Reference Figure 3 , Figure 5 and Figure 6A vertical detection mechanism 700 is mounted on the movable plate 110. The vertical detection mechanism 700 includes a winding roller 710, which is coaxially sleeved on the outside of the main shaft of the drive motor 460. The winding roller 710 is rotatably connected to the movable plate 110 and can be coaxially and fixedly connected to the main shaft of the drive motor 460. A third bolt 740 is threaded through the outside of the winding roller 710 and is used to abut against the main shaft of the drive motor 460. A hanging wire 720 is wound on the outside of the winding roller 710. A guide tube 750 is fixedly connected to the movable plate 110. A plumb bob 730 is fixedly connected to the end of the hanging wire 720 away from the winding roller 710. When inspecting the hollowness and flatness of the wall, the winding roller 710 and the main shaft of the drive motor 460 are in a relative sliding state. When inspecting the verticality of the wall, loosen the first bolt 670 and the second bolt 680, and tighten the third bolt 740 so that the third bolt 740 abuts against the main shaft of the drive motor 460, thus fixing the winding roller 710 and the main shaft of the drive motor 460 in place. After the supervisory personnel raise the moving plate 110 to a certain height using the grip 200 and make all four moving wheels 120 fit against the wall, the main shaft of the drive motor 460 rotates to drive the hanging line 720 on the winding roller 710 to fall, causing the plumb bob 730 to fall naturally. The position of the hanging line 720 coming out of the guide tube 750 is fixed. The verticality of the wall is measured and calculated by measuring the distance between the plumb bob 730 and the wall.

[0049] Reference Figure 6 The plumb bob 730 has a threaded hole 731, and the outer side of the guide tube 750 has a thread that matches the threaded hole 731. When performing wall hollowness detection and wall flatness detection, the plumb bob 730 is tightened onto the guide tube 750 by using the engagement between the threaded hole 731 and the thread on the guide tube 750, which can fix the plumb bob 730 and reduce the possibility of the plumb bob 730 interfering with the normal use of the detection device.

[0050] Reference Figure 1 and Figure 7The gripping component 200 includes a top support rod 210, which is hinged to the movable plate 110. A gripping rod 220 is inserted through one end of the top support rod 210 away from the movable plate 110. The gripping rod 220 is slidably connected inside the top support rod 210. A locking component 230, which is a locking bolt 231, is installed on the top support rod 210 and is threadedly connected to it. Sliding the gripping rod 220 increases the pushing distance of the movable frame 100. Then, by tightening the gripping rod 220 with the locking bolt 231, the stability of the gripping rod 220 is ensured, facilitating detection at higher points on the wall. When not in use, the gripping rod 220 can be slid into the top support rod 210 for easy storage of the detection device.

[0051] The implementation principle of a multi-functional testing device for building supervision in this application embodiment is as follows: the cam 450 is rotatably connected to the moving plate 110 through the rotating rod 451. The main shaft of the drive motor 460 is connected to the rotating rod 451 by the second bolt 680, so that the drive motor 460 drives the cam 450 to rotate. With the cooperation of the spring 440, the striking part 300 can strike the wall. Then, the inspector pushes the moving plate 110 to move on the wall to achieve a comprehensive inspection of the hollowness of the wall.

[0052] When performing wall flatness testing, tighten the first bolt 670 to connect the rotating rod 451 to the connecting rod 610, and at the same time loosen the second bolt 680 to separate the rotating rod 451 from the main shaft of the drive motor 460. After rotating the screw 521 to press the rotating wheel 310 to the four flush positions, start the controller 510 and the distance sensor 500. The tester can then push the moving frame 100 to move to achieve the wall flatness test.

[0053] When performing wall verticality testing, loosen the first bolt 670 and the second bolt 680, and tighten the third bolt 740 to press the main shaft of the drive motor 460 against the wall. Then, push the moving frame 100 to a higher position on the wall, and use the drive motor 460 to drive the winding roller 710 to rotate, which will drive the hanging line 720 on the winding roller 710 to lower, so that the plumb bob 730 hangs down naturally. Then, by measuring the distance between the plumb bob 730 and the wall, the verticality of the wall can be tested. By simply adjusting the testing device, the testing device can perform different functions of testing. At the same time, by connecting multiple mechanisms to each other, compared with directly stacking multiple single-function testing devices, the weight of the equipment is effectively reduced, making it easier for testing personnel to use.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
