Abstract
Description
Technical Field
[0001] This invention relates to the field of building tilt angle measurement technology, specifically a tilt angle measuring device for intelligent building installation engineering. Background Technology
[0002] In construction engineering, many sloping structures are involved, including staircases and aesthetically pleasing structures. During construction, to ensure the stable installation and connection of various components, it is usually necessary to measure their tilt angle. Using tilt angle measuring devices is a common existing method. However, existing tilt angle measuring devices have the following problems when used: Most tilt angle measurements rely on principles such as gravity or plumb, combined with intelligent angle sensors, to determine the angle based on verticality and tilt. However, existing tilt angle measuring devices are inconvenient for measuring internal and external corners, as these corners are in different directions from the plumb line. Consequently, their angles involve calculations during measurement, making the operation cumbersome. Furthermore, existing tilt angle measuring devices are not convenient for cleaning the wall surface being measured. During construction, impurities easily adhere to the wall surface, and these impurities can affect the measurement results during adhesive measurements.
[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing tilt angle measuring devices. Summary of the Invention

An intelligent angle sensor is fixed at the upper mounting shaft, and a counterweight plate is fixedly fitted on the lower mounting shaft. A transmission switching component is provided in the mounting frame, and the transmission switching component is used to switch the transmission state of the first friction wheel on the two mounting shafts. Mounting sleeves are embedded and fixed in the side cavities at the upper and lower ends of the body, and mounting rods are connected to the mounting sleeves through a second elastic telescopic rod. A contact plate is fixed at the outer end of the mounting rod. A rotating component is provided between the mounting rod and the mounting sleeve, and the rotating component is used to realize the rotation of the mounting rod after it moves. A locking assembly is disposed between the mounting rod and the upper first friction wheel, and the locking assembly is used to fix the position of the upper first friction wheel; A limiting component is disposed between the end of the machine body and the outside of the upper mounting rod, and the limiting component is used to limit the position of the mounting rod after it is retracted.
[0006] Preferably, the first friction wheels on the two mounting shafts abut against each other, and the outside of the two first friction wheels is covered with rubber material.
[0007] Preferably, the transmission switching assembly includes a second friction wheel and a side plate, wherein the second friction wheel is rotatably disposed within the mounting frame and is located on one side of the first friction wheel, and the side plate is fixed within the mounting frame and is located inside the mounting plate.
[0008] Preferably, the second friction wheel is arranged parallel to the first friction wheel, and the two first friction wheels are symmetrically arranged about the central axis of the second friction wheel. The side plate is designed as a right trapezoidal structure, and the inclined surface of the side plate abuts against the inner surface of the mounting plate.
[0009] Preferably, the rotating assembly includes a guide head and a guide groove, wherein the guide head is fixed on the mounting rod, the guide head is located inside the guide groove, and the guide groove is formed on the inner wall of the mounting sleeve; The guide head slides in close contact with the guide groove, and the guide groove is distributed in a spiral structure within the mounting sleeve.
[0010] Preferably, the locking assembly includes a push ring sleeved on the mounting rod, and a push post abutting against the inner side of the push ring. The push post is mounted in the machine body by a spring, and an oil tank is fixed to the inner end of the push post. The oil tank is connected to the oil cavity in the first elastic telescopic rod at the upper mounting shaft through a hose, and a piston rod is installed in the oil tank. A locking plate is fixed to the inner end of the piston rod, and the initial state of the locking plate abuts against the upper first friction wheel.
[0011] Preferably, two push rings are provided on the mounting rod, and the two sides of the push rings are designed as inclined structures.

The limiting groove is formed in a ring shape and opened on the outside of the mounting rod.
[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when measuring the tilt angle of a wall, the weight of the counterweight plate drives the lower mounting shaft to rotate, which in turn drives the upper mounting shaft to rotate via the first friction wheel. This, combined with an intelligent angle sensor, allows for angle measurement. Based on this method, when measuring inside and outside corner walls, the contact state of the two first and second friction wheels can be adjusted by moving the mounting plate, changing the transmission direction of the two first friction wheels. This enables switching the measurement direction of the angle. Simultaneously, as the transmission direction changes, the positions of the lower transmission shaft and the counterweight plate also change. This ensures that even when the relative rotation direction changes during tilting, the lower transmission shaft and the counterweight plate still have sufficient room to move, reducing space occupation and facilitating operation. 2. In this invention, two contact discs that contact the wall surface can extend, retract, and rotate. Rotation allows for cleaning of the wall surface, improving detection accuracy. During extension and retraction, the separation and contact between the two push rings and push columns facilitate the contact and release of the upper first friction wheel. After detection, the position of the mounting rod is restricted by the limiting component, which also restricts the position of the first friction wheel, locking the detection angle. This allows operators to visually see the angle on the display screen after detection, even on high walls, without complex operations. The switching of the positions of the two first friction wheels synchronously adjusts the position of the locking plate, still achieving detection and subsequent locking functions, greatly facilitating operator work.

Example 1
[0018] Please see Figures 1-4An installation frame 2 is embedded and fixed inside the body 1. The front and rear sides of the installation frame 2 are connected to the installation base 4 by electric push rods 3. The upper and lower parts of the installation base 4 are respectively connected to the installation plate 6 by the first elastic telescopic rod 5. Two installation shafts 7 are respectively rotatably set inside the corresponding installation plate 6. The two installation shafts 7 are each fitted with a first friction wheel 8. An intelligent angle sensor is fixed at the upper installation shaft 7. A counterweight plate 9 is fixedly fitted on the lower installation shaft 7. A transmission switching component is set inside the installation frame 2. The transmission switching component is used to switch the transmission state of the first friction wheel 8 on the two installation shafts 7. An installation sleeve 11 is embedded and fixed in the side cavity at the upper and lower ends of the body 1. An installation rod 13 is connected inside the installation sleeve 11 by the second elastic telescopic rod 12. The outer end of the installation rod 13 is fixed with a contact plate 14. A locking component is set between the installation rod 13 and the upper first friction wheel 8. The locking component is used to fix the position of the upper first friction wheel 8. The first friction wheels 8 on the two mounting shafts 7 abut against each other, and the exterior of the two first friction wheels 8 is covered with rubber material; the transmission switching assembly includes a second friction wheel 101 and a side plate 102, and the second friction wheel 101 is rotatably mounted in the mounting frame 2, and the second friction wheel 101 is located on one side of the first friction wheel 8. The side plate 102 is fixed in the mounting frame 2, and the side plate 102 is located on the inner side of the mounting plate 6; the second friction wheel 101 is arranged parallel to the first friction wheel 8, and the two first friction wheels 8 are symmetrically arranged about the central axis of the second friction wheel 101. The side plate 102 is designed as a right trapezoidal structure, and the inclined surface of the side plate 102 abuts against the inner surface of the mounting plate 6; the locking assembly includes a push ring 161, the push ring 16 A push ring 161 is mounted on the mounting rod 13, and a push post 162 is abutted against the inner side of the push ring 161.

Then, when the mounting frame 2 is tilted, the lower mounting shaft 7 rotates through the counterweight plate 9, which can adjust the rotation direction of the upper mounting shaft 7. The angle is measured in conjunction with the intelligent angle sensor, and the upper first friction wheel 8 is released and locked by the locking component. Example 2
[0019] Based on Example 1, please refer to Figure 1 and Figures 5-6 A rotating assembly is provided between the mounting rod 13 and the mounting sleeve 11, and the rotating assembly is used to realize the rotation of the mounting rod 13 after it moves; a limiting assembly is provided between the end of the body 1 and the outside of the upper mounting rod 13, and the limiting assembly is used to limit the position of the mounting rod 13 after it is retracted. The rotating assembly includes a guide head 151 and a guide groove 152. The guide head 151 is fixed on the mounting rod 13 and is located inside the guide groove 152. The guide groove 152 is formed on the inner wall of the mounting sleeve 11. The guide head 151 slides in contact with the guide groove 152, and the guide groove 152 is distributed in a spiral structure inside the mounting sleeve 11. The limiting assembly includes a limiting head 171 and a limiting groove 172. The limiting head 171 is embedded in the top of the body 1 by a spring, and the limiting groove 172 is provided on the movement trajectory of the limiting head 171. The limiting groove 172 is formed in a ring structure and is formed on the outer side of the mounting rod 13. Hold the handle on the main body 1 and press the two contact plates 14 against the wall. As the mounting rod 13 goes into the mounting sleeve 11, the rotating component drives the mounting rod 13 and the contact plates 14 to rotate, cleaning the wall. The position of the mounting rod 13 is limited by the limiting component.
[0020] Working principle: First, based on the measurement of the inside and outside corners of the wall, the mounting base 4 is moved by the electric push rod 3. The mounting base 4 drives the mounting plate 6 to move through the first elastic telescopic rod 5. The inner side of the mounting plate 6 contacts the inclined surface of the side plate 102, so that the upper and lower mounting plates 6 move in opposite directions, driving the mounting shaft 7 and the first friction wheel 8 to move. This causes the upper and lower first friction wheels 8 to gradually separate and move towards the second friction wheel 101. Finally, the two first friction wheels 8 contact the second friction wheel 101. At this time, the two first friction wheels 8 are driven by the second friction wheel 101, changing the transmission state of the two first friction wheels 8. By changing the position of the first friction wheels 8, the counterweight plate 9 can have better movement space when the body 1 is tilted, which helps to reduce space occupation. At the same time, the retraction of the upper first elastic telescopic rod 5 introduces the internal oil into the oil tank 163 through the hose, driving the piston rod 164 and the locking plate 165 to move upward, so that the locking plate 165 is always in contact with the upper first friction wheel 8, fixing its initial position. After adjustment, hold the handle on the machine body 1, place the two contact plates 14 on the wall to be tested and press them down, so that the mounting rod 13 enters the mounting sleeve 11. Under the transmission action of the guide head 151 and the guide groove 152, the mounting rod 13 and the contact plate 14 are driven to rotate, cleaning the wall surface. At the same time, the rotation and movement of the mounting rod 13 causes the first push ring 161 to leave the push column 162. The push column 162 is reset under the action of the spring, which in turn drives the oil tank 163, piston rod 164 and locking plate 165 to move upward, so that the locking plate 165 separates from the upper first friction wheel 8. At this time, the positions of the two first friction wheels 8 are released. Under the action of gravity, the counterweight plate 9 falls freely and remains perpendicular to the ground. Since the counterweight plate 9 is fixed to the mounting shaft 7, it carries... The lower mounting shaft 7 and the first friction wheel 8 rotate, which in turn drives the upper first friction wheel 8 to rotate via the second friction wheel 101. As the mounting rod 13 extends, the limiting head 171 pops out under the action of the spring and locks into the limiting groove 172, fixing the position of the mounting rod 13. At the same time, the second push ring 161 moves to the push post 162, causing the locking plate 165 to move down and again contact the upper first friction wheel 8, thereby fixing the upper mounting shaft 7. The intelligent angle sensor on it detects the rotation angle and displays it through the built-in microcontroller and external display for easy observation. In subsequent use, the rod connected to the limit head 171 is pulled to release the position of the mounting rod 13, allowing it to be used again. The operation is simple.
