Description

Technical Field

[0001] The invention relates to the technical field of construction engineering detection devices, and in particular to a construction engineering detection device for tilt detection. Background Art

[0002] In the field of construction engineering, the tilt detection of buildings, structures and slopes is a vital task. The tilt problem not only affects the appearance and usability of the building, but is also likely to endanger the structural safety and cause immeasurable losses. The traditional tilt detection method has many shortcomings. The ruler, also known as the detection ruler, is a precision tool for measurement and detection. It is widely used in construction, decoration, engineering and other fields. It can accurately measure key indicators such as straightness and verticality. For tilt detection, the horizontality or slope of the detected surface can be judged by observing whether the horizontal bubble on the ruler is centered, thereby achieving the purpose of tilt detection.

[0003] In the prior art, there is a construction measuring ruler with publication number CN112629393A, which includes a folding ruler and a lock, and is equipped with a flatness detection device and a probe baffle. Several flatness detection devices are fixedly arranged at equal intervals in the folding ruler. A probe placement groove is arranged in the box of the flatness detection device, and the probe can be slidably arranged in the probe placement groove. A probe spring is arranged between the probe and the probe placement groove to allow the probe end to extend out of the probe through hole. The above-mentioned document can reduce the work intensity of the measurement personnel, improve the measurement efficiency, and can more clearly obtain the overall situation of the wall flatness.

[0004] In the prior art, there is a construction measuring ruler with publication number CN112629393A, which includes a folding ruler and a lock, and is equipped with a flatness detection device and a probe baffle. Several flatness detection devices are fixedly arranged at equal intervals in the folding ruler. A probe placement groove is arranged in the box of the flatness detection device, and the probe can be slidably arranged in the probe placement groove. A probe spring is arranged between the probe and the probe placement groove to allow the probe end to extend out of the probe through hole. The above-mentioned document can reduce the work intensity of the measurement personnel, improve the measurement efficiency, and can more clearly obtain the overall situation of the wall flatness.

[0005] However, in actual use, traditional building measurement adopts a relatively simple measurement principle when detecting the inclination of a building, which leads to large measurement errors. In addition, it is impossible to switch between measurement modules with different functions during the measurement, and the measurement is single.

The aim is to break through the single measurement limitation of the traditional straightedge, create a multi-functional and intelligent detection tool, break through the physical measurement limitation of the traditional straightedge, and create an "all-round tool platform" for building detection.

[0023] Embodiment 2, refer to the attached Figure 1-18 , based on the first embodiment, in order to realize the switching of multiple measurement modes and increase the versatility of device detection: The outer side surface of the spirit level 3 is fixedly connected to the inner side surface of the mounting end 31. The frame-shaped guard plate 32 has a "C"-shaped frame structure and is fixedly connected to the mounting end 31. A first reserved groove 320 is formed in the inner wall of the side of the frame-shaped guard plate 32 away from the mounting end 31, and a moving assembly is arranged inside the first reserved groove 320; the moving assembly includes a guide rod 321, the outer surface of the guide rod 321 is slidably connected to the inner walls of both sides of the frame-shaped guard plate 32, a traveling wheel 322 is arranged at one outer end of the guide rod 321, the outer surface of the traveling wheel 322 is in rolling connection with the inner wall of the side rail 1011, and a fixed hook plate 323 is fixedly installed at the end of the guide rod 321 away from the traveling wheel 322; a second movable groove 32000 is formed at the back end of the frame-shaped guard plate 32, the second movable groove 32000 communicates with the inner wall of the first reserved groove 320, the inner surface of the second movable groove 32000 is slidably connected to the outer surface of the fixed hook plate 323, a curved elastic piece is fixedly connected to one side of the fixed hook plate 323, the other end of the curved elastic piece is fixedly connected to the side wall of the first reserved groove 320, and the curved elastic pieces are symmetrically distributed on both sides of the guide rod 321; a first movable groove 3200 is formed through the upper end of the first reserved groove 320, an elastic sealing piece 3201 is fixedly connected to the inner surface of the first movable groove 3200, a stress bar 324 is fixedly installed on one side of the elastic sealing piece 3201, the stress bar 324 has an "L"-shaped structure, the upper end of the stress bar 324 extends to the outside of the frame-shaped guard plate 32, and the other end of the stress bar 324 is fixedly connected to the surface of the fixed hook plate 323; In this embodiment, when it is necessary to switch the detection mode of the device, the spirit level 3 inside the placement groove 101 is replaced. Here, the spirit level 3 can be a spirit level, a rangefinder or an angle sensor. The placement groove 101 is used for storing instruments in different modes. Specifically, when installing the spirit level 3, hold the mounting end 31 and push the spirit level 3 and the frame-shaped guard plate 32 into the inside of the placement groove 101. At this time, the traveling wheels 322 on both sides of the frame-shaped guard plate 32 first come into rolling contact with the side wall of the side rail 1011. It should be particularly noted that the side rail 1011 changes from a narrow channel to a wide channel from the outside to the inside, and a slope is connected between the narrow channel and the wide channel. When the spirit level 3 continues to be pushed and completely reaches the wide channel, the traveling wheel 322 contacts the inner wall of the wide channel, and at this time, the stress bar 324 slides inside the first movable groove 3200. The traveling wheel 322 is abutted against the inner wall of the wide channel by the elastic acting forces of the elastic sealing piece 3201 and the curved elastic piece to prevent loosening without external force influence; It is worth noting that, as Figure 5As shown, when the walking wheels 322 enter the wide road, the fixed hook plates 323 connected to the guide rods 321 move synchronously. At this time, the two groups of fixed hook plates 323 move relatively outward, so as to achieve the snap connection with the side walls of the reserved groove 2 100. At this time, the level 3 is automatically locked with the ruler 1. When it is necessary to switch to other measurement modes to disassemble and replace the level 3, the operator only needs to squeeze the two groups of fixed hook plates 323 toward the middle. At this time, the fixed hook plates 323 drive the two groups of walking wheels 322 to be retracted inward for a distance. At the same time, the handheld mounting end 31 can pull the level 3 outward as a whole. It should be noted that the elastic sealing sheet 3201 here can not only limit the movement of the force strip 324, but also assist in sealing the movable groove 1 3200 to prevent dust from entering the construction site, thereby achieving a dust-proof effect and realizing multiple uses of one item.

[0024] Embodiment 3, refer to the attached Figure 1-18 On the basis of the second embodiment, in order to expand the versatility of the detection device, a flexibly expandable auxiliary ruler 2 is added: One end of the auxiliary ruler 2 is rotatably connected with a pin shaft 21, and the pin shaft 21 is fixedly installed on the inner wall of the auxiliary ruler groove 10. The end of the auxiliary ruler 2 away from the pin shaft 21 is sleeved with an end cover 22, and a telescopic arm 23 is arranged on the inner side of the end cover 22. The end of the telescopic arm 23 close to the pin shaft 21 is provided with an electric telescopic rod 231, and the end of the telescopic arm 23 away from the electric telescopic rod 231 is fixedly installed with a detection feeler 232; a circular hole is opened on the side wall of the auxiliary ruler groove 10 close to the placement groove 101, and the inner surface of the circular hole is movably connected with the outer surface of the detection feeler 232, and the telescopic arm 23 is close to the pin shaft 21. Both sides of one end of the near detection feeler 232 are respectively set as inclined surfaces, and an auxiliary protection component is set on the outer side of the inclined surface. The auxiliary protection component includes a lining plate 24, a supporting plate 241 and an arc-shaped elastic wire 242. The supporting plate 241 is fixedly installed on the inner wall of one end of the auxiliary ruler groove 10, and one end of the supporting plate 241 is movably connected to the outer surface of the lining plate 24. The outer surface of the supporting plate 241 is set as a rounded corner, and the outer surface of the rounded corner is movably abutted against the inclined surface. One end of the arc-shaped elastic wire 242 is fixedly connected to the inside of the auxiliary ruler groove 10, and the other end of the arc-shaped elastic wire 242 is fixedly connected to the inner side surface of the supporting plate 241; In this embodiment, an auxiliary ruler groove 10 is provided on the scale surface of the ruler 1 and the ruler 2 11 to store the auxiliary ruler 2. The surface of the auxiliary ruler 2 is flush with the scale surface of the ruler 1. It is worth noting that the inner side of the auxiliary ruler 2 is integrated with an intelligent electric telescopic rod 231. When the auxiliary ruler 2 is completely stored in the auxiliary ruler groove 10, the two ends thereof can realize the contraction and expansion of the telescopic arm 23 and the detection contact foot 232 through the intelligent telescopic movement of the electric telescopic rod 231, and adjust the telescopic process of the electric telescopic rod 231. When the electric telescopic rod 231 controls the telescopic arm 23 to move forward, the inclined surfaces on both sides of the telescopic arm 23 fit with the inner side of the supporting plate 241. At this time, the arc-shaped elastic wire 242 is deformed, and its reverse elastic force can clamp the side of the telescopic arm 23. When the detection feeler 232 enters the circular hole, not only the telescopic arm 23 is locked, but also the detection feeler 232 is hidden and stored synchronously to avoid direct exposure to the outside, and the auxiliary ruler 2 can be locked to avoid loosening when the device is used as a horizontal measuring ruler; and when the detection feeler 232 is separated from the circular hole, the auxiliary protection component here can also serve as a blocking member of the circular hole to prevent contamination by external dust; a cleaning brush 221 is provided on the inner side of the end cover 22 for auxiliary cleaning of the telescopic arm 23.

[0025] Embodiment 4, refer to the attached Figure 1-18 On the basis of the third embodiment, in order to prevent the traditional detection device from being unable to detect narrow gaps, the device integrates a hidden detection mechanism: The adapter plate 4 is fixedly installed on the inner side of the mounting groove 40, the bottom end of the adapter plate 4 is fixedly connected to the sleeve seat 41, the inner surface of the adapter plate 4 is provided with a cylindrical groove, and the inner surface of the cylindrical groove is adapted to be installed with a cylindrical sleeve 42; the pushing component includes an air guide tube 43, a cylindrical plug 431, a pushing piston 421 and a detection arm 423, the cylindrical plug 431 is fixedly installed at the bottom end of the cylindrical sleeve 42, the air guide tube 43 passes through the bottom end of the sleeve seat 41 and extends to the inside of the cylindrical plug 431, the inner wall of the cylindrical plug 431 is provided with an annular cavity, and the upper end of the annular cavity is connected to the cylindrical sleeve The inner wall of the cylinder 42 is connected through, and the inner surface of the cylindrical sleeve 42 is slidably connected to the outer surface of the push piston 421; the lower end of the push piston 421 is fixedly connected with a flexible wiring 4211, and the upper end of the push piston 421 is fixedly installed with a push plug rod 422, and the upper end outer surface of the push plug rod 422 is provided with a joint, and the joint is electrically connected with the flexible wiring 4211; the top of the push plug rod 422 is fixedly installed with a detection arm 423, and the outer side of the detection arm 423 is movably connected with a conical sleeve 411, and the conical sleeve 411 is fixedly installed on the top of the socket 41; In this embodiment, a mounting groove 40 is provided on the inner wall of one side of the ruler 1 and the ruler 2 11 for concealed storage of the hidden detection mechanism. When it is necessary to detect a narrow gap, it is only necessary to control the detection arm 423 to extend. At this time, the folded ruler is in contact with the wall, and the detection at the gap is performed by relying on the extended detection arm 423. Specifically, pressurized gas is introduced into the annular cavity of the cylindrical plug 431 through the air guide tube 43. At this time, the pressurized gas enters the bottom surface of the inner cavity of the cylindrical sleeve 42, pushes the push piston 421 to rise, and drives the push plug rod 422 and the detection arm 423 to move upward. At this time, the detection arm 423 is extended to realize detection at the narrow gap. This function can integrate image acquisition equipment to monitor the engineering conditions of the construction site in real time. In addition, a conical sleeve 411 is connected to the top of the socket 41, and the conical sleeve 411 is set to a soft silicone material. When the detection arm 423 is recovered, dust and impurities on the surface of the detection arm 423 can be scraped off.

[0026] Embodiment 5, refer to the attached Figure 1-18 Based on the fourth embodiment, the present invention further proposes a method for using a construction engineering detection device for tilt detection, comprising the following steps: Step 1: Mode switching and measurement preparation: According to the detection requirements, take out the level 3, rangefinder or angle sensor module from the placement slot 101 of the ruler 1, align the target module with the placement slot 101 and insert it, guide it from the narrow track to the wide track through the side rail 1011, make the walking wheel 322 abut against the inner wall of the wide track, and at the same time, the fixed hook plate 323 is engaged with the side wall of the reserved slot 2 100 to complete the automatic locking; Step 2: Tilt detection operation: Place the scale surface of the ruler 1 close to the measured surface, and read the tilt angle through the level 3 or the angle sensor. If distance measurement is required, start the distance meter module and press the measurement button to obtain the distance data. In a narrow space or when additional support is required, unfold the auxiliary ruler 2 vertically to the ground as an auxiliary support for the ruler tilt measurement to reduce the pressure of hand support; Step 3: Narrow gap detection: When cracks or narrow areas need to be detected, pressurized gas is injected into the cylindrical plug 431 through the air guide tube 43 to push the piston 421 upward, driving the detection arm 423 to extend out of the conical sleeve 411. The top of the detection arm 423 is integrated with an image acquisition device to transmit the internal image of the crack or gap to the ruler display or mobile phone APP in real time. After the detection is completed, the gas pressure is released, the detection arm 423 is automatically recovered, and the conical sleeve 411 scrapes off the dust and impurities on the surface; Step 4: Support and folding for storage: When using on an uneven surface, unfold the support foot 5 in the receiving slot 50 and connect it to the bottom of the ruler by magnetic attraction to ensure the stability of the device. After the detection is completed, fold the ruler 1 and the ruler 2 11 together, push the fixed hook plate 323 to unlock the level 3, take out the module and store it in the placement slot 101, retract the auxiliary ruler 2 into the auxiliary ruler slot 10, and the detection contact foot 232 is automatically hidden in the circular hole to complete the overall storage.
