Description

Technical Field

[0001] This utility model relates to the field of tilt measurement technology, specifically to a portal frame tilt measuring instrument. Background Technology

[0002] Inclination measurement is a measurement method that uses professional instruments or methods to obtain data such as the angle and slope between an object and a horizontal or vertical reference plane. Its core purpose is to ensure structural safety, equipment accuracy, or engineering quality.

[0003] In the construction industry, when installing portal frames, it is necessary to measure their tilt. A common measurement method is the plumb line measurement method. This involves suspending a weight at the top of the portal frame and measuring the horizontal distance between the plumb line and the portal frame. Measured at two points, one above and one below, the difference is the tilt deviation, which is then converted into tilt. The detection method of a laser level is similar. The laser level is adjusted to a horizontal state and turned on. Using the projected vertical laser line as a reference, the distance between the portal frame and the vertical laser line is measured. Measured at two points, one above and one below, the tilt is calculated in the same way as the plumb line measurement method. Both of the above common methods have some shortcomings. The plumb line measurement method is easily affected by the environment. For example, a slight breeze or vibration can cause the plumb line to swing, making it impossible to measure stably. Laser levels are susceptible to interference from ambient light, which can decrease in strong light conditions, making measurements more difficult. They also require a high degree of flatness of the ground, so the laser level needs to be leveled before measurement. Leveling errors will be directly transmitted to the measurement results, leading to inaccurate data. In summary, both of the above-mentioned common measurement methods have the problem of inconvenience in actual use. That is, they both require measuring the distance between the vertical line or light and the portal frame to obtain the tilt angle from the side. Therefore, a portal frame tilt angle measuring instrument is proposed to solve the above-mentioned problems. Utility Model Content

The mounting bracket contains a small laser and a counterweight. The small laser and the counterweight are used to keep the vertical measuring component vertical by gravity. The light-transmitting hole is used to ensure that the beam emitted by the small laser can penetrate the vertical measuring component. The interior of the vertical measuring component is filled with water.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the transverse bar includes a crossbar body, one end of which is provided with a hinge groove, and a scale is provided on one side surface of the crossbar body, the scale being located near the hinge groove.

[0008] Furthermore, the vertical rod includes a hinge block, which is disposed inside the hinge groove and has threaded rods on both sides. Both threaded rods pass through the hinge groove and extend to the outside of the hinge groove, with one threaded rod passing through the center of the scale.

[0009] Furthermore, each of the two threaded rods has a nut at one end extending outside the hinge groove. The nut is threadedly connected to the threaded rod and is tightly fitted to the outer surface of the scale and one side of the crossbar, respectively. The nut and the threaded rod cooperate with each other to connect and fix the crossbar and the vertical rod together.

[0010] Furthermore, the top of the hinge block is provided with a vertical rod body, and on the surface of the vertical rod body facing the scale, a second pointer, a mounting hole and a first pointer are provided from top to bottom. The bottom ends of the first pointer and the second pointer are both arrow-shaped, and the arrow of the first pointer points to the scale.

[0011] Furthermore, the vertical measuring component includes a transparent hollow disc, the interior of which is provided with a water storage cavity, the interior of which is filled with water, the water occupying half of the space of the transparent hollow disc, the transparent hollow disc having a light-transmitting hole along its radial direction, and an angle scale being provided on the surface of the side facing away from the vertical rod.

[0012] Furthermore, a rotating shaft is provided at the center of the transparent hollow disk facing the vertical rod.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0020] like Figure 1 and Figure 2 As shown, a portal frame tilt measuring instrument includes: an L-shaped hinge frame, a vertical measuring component 4, and a small laser 5; The L-shaped hinge frame includes a horizontal rod 1 and a vertical rod 2, which are hinged to each other. The vertical measuring component 4 is connected to the vertical rod 2 via bearings and includes a light-transmitting hole 43 and a mounting bracket 45. The mounting bracket 45 is equipped with a small laser 5 and a counterweight 6. The small laser 5 and the counterweight 6 are used to keep the vertical measuring component 4 vertical by gravity. The light-transmitting hole 43 is used to ensure that the beam emitted by the small laser 5 can penetrate the vertical measuring component 4. The interior of the vertical measuring component 4 is filled with water. Based on the above, the horizontal rod 1 and the vertical rod 2 are hinged to each other, so that the angle between them can be adjusted. The horizontal rod 1 and the vertical rod 2 can be used as an angle ruler to measure directly. The measured angle is the angle between the two rods. The setting of the vertical measuring component 4 and the water body can determine whether the vertical rod 2 is in a vertical state by the state of the water body, and cooperate with the vertical rod 2 to determine the tilt angle of the vertical rod 2 when the vertical state is used as a reference. The arrangement of the miniature laser 5 and the light-transmitting aperture 43 enables the device to measure the far end of the portal frame using the emitted light beam.

[0021] like Figures 1-4 As shown, the horizontal bar 1 includes a horizontal bar body 11, one end of which is provided with a hinge groove 12, and a scale 13 is provided on one side surface of the horizontal bar body 11, the scale 13 being located on the side close to the hinge groove 12. like Figure 5 As shown, the vertical rod 2 includes a hinge block 22, which is disposed inside the hinge groove 12 and has threaded rods 23 on both sides. Both threaded rods 23 pass through the hinge groove 12 and extend to the outside of the hinge groove 12. One threaded rod 23 passes through the center of the scale 13. Nuts 3 are provided at the ends of the two threaded rods 23 that extend to the outside of the hinge groove 12. The nuts 3 are threadedly connected to the threaded rods 23 and are tightly fitted to the outer surface of the scale 13 and one side of the horizontal rod body 11, respectively. The nuts 3 and the threaded rods 23 cooperate with each other to connect and fix the horizontal rod 1 and the vertical rod 2 to each other. The top of the hinge block 22 is provided with a vertical rod body 21. On the surface of the vertical rod body 21 facing the scale 13, a second pointer 26, a mounting hole 25 and a first pointer 24 are provided from top to bottom. The bottom ends of the first pointer 24 and the second pointer 26 are both arrow-shaped, and the arrow of the first pointer 24 points to the scale 13. Based on the above, the horizontal rod 1 is hinged to the vertical rod 2 via the threaded rod 23, allowing the horizontal rod 1 and the vertical rod 2 to move around the threaded rod 23 as the center, thus changing the tilt angle between the horizontal rod 1 and the vertical rod 2. In actual use, by placing the horizontal rod 1 on the ground and moving the vertical rod 2 so that the vertical rod 2 tilts and becomes parallel or coincident with the portal frame, the tilt angle can be obtained by directly reading the value when the first pointer 24 points to the scale 13. The second pointer 26 cooperates with the vertical measuring component 4 to obtain the tilt angle of the vertical rod 2 with the vertical direction as a reference, and the mounting hole 25 allows the vertical measuring component 4 to be connected to it.

[0022] like Figure 1 , Figure 2 , Figures 6-8 As shown, the vertical measuring component 4 includes a transparent hollow disk 41. The transparent hollow disk 41 has a water storage cavity 44 inside, which is filled with water. The water occupies half of the space of the transparent hollow disk 41. The transparent hollow disk 41 has a light-transmitting hole 43 along its radial direction, and an angle scale is provided on the surface opposite to the vertical rod 2. The inner wall of the light-transmitting hole 43 is provided with a reflective layer to avoid light beam refraction interference. A rotating shaft 42 is provided at the center of the transparent hollow disk 41 facing the vertical rod 2. The rotating shaft 42 extends into the interior of the mounting hole 25 and is connected to the mounting hole 25 through a bearing to ensure that the transparent hollow disk 41 can rotate around the rotating shaft 42. A mounting bracket 45 is provided on the circumferential surface of the transparent hollow disk 41, located at one end of the light-transmitting hole 43. The mounting bracket 45, from top to bottom, has a first mounting groove 46 and a second mounting groove 47 on the side away from the vertical rod 2. A small laser 5 is provided inside the first mounting groove 46, and the laser beam emitted from the laser emitting end of the small laser 5 is emitted along the direction of the light-transmitting hole 43. A counterweight 6 is provided inside the second mounting groove 47. A cover plate 48 is provided on the side of the mounting bracket 45 away from the vertical rod 2. The cover plate 48 is used to fix the small laser 5 and the counterweight 6. The small laser 5 is preferably a laser of model ML650-10G1, and is powered by a built-in battery. The transparent hollow disk 41 is located directly below the second pointer 26, and the arrow of the second pointer 26 points to the angle scale of the transparent hollow disk 41; Based on the above, when the water storage cavity 44 is filled with half of the space with water, the water will divide the water storage gun 44 into two parts, so that the user can use the horizontal plane and the angle scale to observe whether the vertical measuring component 4 is in a vertical state, and use the vertical measuring component 4 in this state as a reference for observation. The small laser 5 and the counterweight 6 are designed to lower the center of gravity, allowing the vertical measuring component 4 to remain vertical under the influence of gravity. The light-transmitting hole 43 ensures that the beam emitted by the small laser 5 can pass through the vertical measuring component 4 and remain in a straight line.

[0023] The working principle is as follows: Benchmark calibration: Before measurement, loosen nut 3 so that horizontal rod 1 and vertical rod 2 can rotate freely. Under the action of counterweight 6 and gravity, transparent hollow disk 41 rotates around rotating axis 42. Observe whether the water in water storage cavity 44 is horizontal. If the water is stable, transparent hollow disk 41 is in a vertical state. At this time, the second pointer 26 points to 0° on the angle scale, and the laser beam is an absolute vertical reference. Direct angle measurement: Place the horizontal bar 1 against the crossbeam of the portal frame or the ground, rotate the vertical bar 2 so that the bar body 21 is against the surface of the frame column, tighten the nut 3 to fix the angle, and read the value of the first pointer 24 on the scale 13. This value is the tilt angle of the portal frame. At the same time, observe the value of the second pointer 26 on the angle scale of the transparent hollow disk 41. If the value is 0°, it means that the contact surface of the horizontal bar 1 is horizontal and the measurement data is accurate. If there is a numerical deviation, the tilt angle can be corrected based on the deviation to further improve the measurement accuracy. Long-distance measurement: For portal frames with large spans, turn on the small laser 5, and the beam is emitted along the light-transmitting hole 43 to form a vertical baseline. Place a ruler at the far end of the frame and read the projection position of the beam on the ruler. By combining the measurement distance and the ruler reading, the tilt deviation of the far-end column can be quickly determined, and the tilt of the entire frame can be detected.

[0024] In summary, this measuring instrument can directly read the design through the angle of the L-shaped hinged frame, eliminating the need to calculate the tilt angle through distance difference, reducing the operation steps by more than 50%. Furthermore, the setting of the vertical measuring component 4 allows the measuring instrument to measure directly without relying on a flat ground, making it suitable for complex outdoor terrain scenarios. By using a small laser 5, measurements can be taken at the far end of the portal frame.
