Description

Technical Field

[0002] A tilt detection device used in building construction is a professional instrument used to monitor the tilt status and degree of tilt of buildings, structural components or equipment. It obtains parameters such as the tilt angle and offset of the object being measured, providing key data support for engineering quality control and structural safety assessment.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing tilt detection devices typically use a level and an angle dial to measure the tilt angle, lacking a structure that provides an alarm when tilt is detected. As a result, in practical applications, even when the tilt of a building at a construction site exceeds the safety threshold, relevant personnel cannot detect it in time, thus missing the tilt change information and increasing the risk of local collapse.

[0004] Therefore, a tilt detection device for building construction is proposed. Utility Model Content

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A tilt detection device for building construction includes a fixed base 1, a support column 2 welded to the top of the fixed base 1, a connecting mechanism 3 welded to the top of the support column 2, and a detection mechanism 4 installed on the left side surface of the connecting mechanism 3.

The PLC controller 47 can receive the electrical signals of the tilt sensor 41, the absolute encoder 42, the laser displacement transmitter 44 and the laser displacement receiver 45, and can control the buzzer warning light 46 to issue the sound and light alarm.

[0029] Specifically, such as Figure 3 As shown, the connecting mechanism 3 includes a support plate 31, a limiting groove 32, a torsion spring 33, a rotating rod 34, a connecting plate 35, a connecting screw hole 36, and a connecting screw 37. The support plate 31 is welded to the top of the support column 2.

[0030] Specifically, such as Figure 3 As shown, the mounting slot 43 is opened on the top of the support plate 31, the buzzer warning light 46 is installed on the front side of the top of the support plate 31, the PLC controller 47 is installed on the left side of the support plate 31, the limit slot 32 is opened on the inner side of the top of the support plate 31, the torsion spring 33 is rotatably connected to both sides of the inner side of the limit slot 32, the absolute encoder 42 is installed on the left side of the torsion spring 33, and the rotating rod 34 is fixedly connected to the surface of the torsion spring 33.

[0031] Specifically, such as Figure 3As shown, the tilt sensor 41 is installed on the surface of the left side of the rotating rod 34, the laser displacement receiver 45 is installed on the surface of the right side of the rotating rod 34, the connecting plate 35 is welded to the rear side of the top of the rotating rod 34, the connecting screw hole 36 is opened at the chamfer of the connecting plate 35, and the connecting screw 37 is threaded into the inner side of the connecting screw hole 36.

[0032] In this embodiment: By setting the support plate 31 as the connecting carrier between the detection mechanism 4 and the support column 2, a stable installation plane is provided, enhancing the overall structural rigidity. The limiting groove 32 and the torsion spring 33 can limit the rotation angle range of the rotating rod 34, preventing excessive rotation from damaging the internal structure. At the same time, the elastic reset function of the torsion spring 33 facilitates the quick restoration of the initial detection position. The rotating rod 34 can support and limit the connecting plate 35 and the detection mechanism 4. The connecting plate 35 is in direct contact with the building surface. The connecting screw hole 36 can support and limit the connecting screw 37. The connecting screw 37 can fix the connecting plate 35 to the building surface.

[0033] Specifically, such as Figure 4 As shown, a fixing screw hole 5 is provided at the chamfer of the fixing base 1, and a fixing screw 6 is threaded to the inner side of the fixing screw hole 5.

[0034] Specifically, such as Figure 4 As shown, several reinforcing rods 7 are welded to the top of the fixed base 1, and the surface of the reinforcing rods 7 is coated with anti-corrosion paint.

[0035] In this embodiment: by setting the fixing screw hole 5 and cooperating with the fixing screw 6, the device can be quickly fixed by screwing it into the ground, wall or other mounting surfaces. By setting the fixing screw 6, the fixing base 1 can be quickly installed on the ground. By setting the reinforcing rod 7, the stability of the connection between the fixing base 1 and the support plate 31 is increased. By setting the anti-corrosion coating, it can resist the erosion of construction mud, rainwater and acid and alkali substances, and extend the service life of the device.

[0036] Specifically, such as Figure 4 As shown, reinforcing rings 8 are welded to both the bottom and top of the support column 2, and the surface of the reinforcing rings 8 is coated with anti-corrosion paint.

[0038] In this embodiment: by setting a reinforcing ring 8, the connection strength between the support column 2 and the base and connecting mechanism 3 is enhanced; by setting an anti-corrosion coating, it has anti-ultraviolet and waterproof properties, which can prevent metal oxidation and rust during outdoor construction and ensure that the support column 2 maintains structural stability for a long time; by setting a rubber gasket 9, the high elasticity and anti-slip texture increase the friction between the connecting plate 35 and the support plate 31 when tightening the screw, preventing the rotating rod 34 from shifting at an angle due to external force during the testing process.

[0039] Working principle: First, the operator places the fixed base 1 at the detection position and installs it on a flat surface such as the ground or wall through the fixing screw hole 5 and fixing screw 6. Next, the operator rotates the connecting plate 35 to a suitable angle, and at the same time, uses the connecting screw 37 to pass through the connecting screw hole 36 to fix the rotating rod 34. Then, the detection mechanism 4 starts to work. The tilt sensor 41 collects the tilt angle data of the rotating rod 34 in real time. The laser displacement emitter 44 emits a laser signal upward from the mounting groove 43, and the laser displacement receiver 45 receives the signal and monitors the laser displacement change. The two types of sensors transmit the collected electrical signals to the PLC controller 47 for processing and analysis. Then, the PLC controller 47 integrates and calculates the data from the tilt sensor 41, absolute encoder 42, laser displacement transmitter 44, and receiver, and compares them with preset thresholds. Once the detected value exceeds the safe range, it immediately sends a command to the buzzer warning light 46. Finally, after receiving the command from the PLC controller 47, the buzzer warning light 46 simultaneously issues an audible and visual alarm to remind on-site personnel to promptly detect the abnormality and take appropriate measures to avoid safety hazards caused by tilting.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
