Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, specifically to a high-altitude beam measuring ruler. Background Technology

[0002] In building construction, beams refer to structural members whose primary deformation is bending, mainly bearing bending moment and shear force. Beams play a crucial role in the superstructure of a building, supporting its weight and being one of the most important parts of the superstructure framework. Beams come in various forms. Functionally, they can be categorized as structural beams, such as foundation beams and frame beams, which, together with columns and load-bearing walls, form a spatial structural system; and as construction beams, such as ring beams, lintels, and connecting beams, which play a structural role in crack resistance, earthquake resistance, and stability. According to engineering attributes, they can be classified as frame beams, shear wall-supported frame beams, internal frame beams, shear wall connecting beams, shear wall concealed beams, and shear wall edge beams. When measuring the height and width of existing high-altitude beams, measuring tapes and rulers are typically used, and ladders, lifting platforms, cranes, and other aerial work platforms are often required for measurement.

[0003] When using existing measuring tools to measure the dimensions of high-altitude beams, the measurement is not only inconvenient and cumbersome, resulting in low efficiency, but also poses a danger to high-altitude operations. This solution addresses the aforementioned technical problems. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-altitude beam measuring ruler, comprising a measuring mechanism for measuring the dimensions of the beam, and a rod connected to the measuring mechanism. The measuring mechanism includes a support block rotatably connected at one end to one end of the rod, a ruler vertically disposed on the side of the support block, a slider slidably disposed on the ruler, and a driving component for driving the slider to move. A laser ranging module one is disposed at the other end of the support block, a laser ranging module two is disposed on the side of the slider facing the support block, a baffle is disposed at the top of the slider, and a limit switch is disposed on the side of the baffle. The limit switch is detachably abutted against the side of the support block on both sides of the beam, and the limit switch is electrically connected to the driving component, the laser ranging module one, and the laser ranging module two, respectively.

[0008] The rod body includes an inner rod that is rotatably connected to the support block at one end, and an outer tube that slides through the other end of the inner rod. One end of the outer tube is provided with a locking ring for locking the inner rod, and the control module is located at the other end of the outer tube.

[0026] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] See Figures 1-7A high-altitude beam measuring ruler includes a measuring mechanism 1 for measuring beam dimensions and a rod 2 connected to the measuring mechanism 1. The measuring mechanism 1 includes a support block 11 with one end rotatably connected to the other end of the rod 2, a ruler 12 vertically disposed on the side of the support block 11, a slider 13 slidably disposed on the ruler 12, and a driving assembly 14 for driving the slider 13 to move. A laser ranging module 111 is disposed at the other end of the support block 11. A laser ranging module 131 is disposed on the side of the slider 13 facing the support block 11. A baffle 132 is disposed at the top of the slider 13. A limit switch 133 is disposed on the side of the baffle 132. The limit switch 133 is detachably abutted against the side of the support block 11 on both sides of the beam. The limit switch 133 is electrically connected to the driving assembly 14, the laser ranging module 111, and the laser ranging module 131 respectively.

[0028] A control module 7 is provided on the rod body 2. The drive assembly 14, limit switch 133, laser ranging module one 111, and laser ranging module two 131 are electrically connected to the control module 7. The control module 7 is provided with operation buttons 72 and a display screen 71 for displaying measurement information.

[0029] More specifically, the support block 11 is equipped with a battery that supplies power to the laser ranging module 111 and the motor 144, the slider 13 is equipped with a battery that supplies power to the laser ranging module 131 and the limit switch 133, the control module 7 has a separate battery, and the rod 2 is equipped with the control module 7. The drive assembly 14, the limit switch 133, the laser ranging module 111, and the laser ranging module 131 are electrically connected to the control module 7 via wireless means, including but not limited to data transmission methods such as Bluetooth and Wi-Fi.

[0030] The drive assembly 14 includes a main synchronous pulley 141 and a driven synchronous pulley 142 respectively rotatably disposed on the side of the ruler body 12, a synchronous belt 143 tensioned between the main synchronous pulley 141 and the driven synchronous pulley 142, the synchronous belt 143 being connected to the slider 13, the main synchronous pulley 141 being connected to a motor 144, and the motor 144 being electrically connected to a limit switch 133.

[0031] The rod body 2 includes an inner rod 21 that is rotatably connected to the support block 11 at one end, and an outer tube 22 that slides through the other end of the inner rod 21. One end of the outer tube 22 is provided with a locking ring 221 for locking the inner rod 21, and the control module 7 is provided at the other end of the outer tube 22.

[0032] One end of the inner rod 21 is provided with a hinge seat 211, and one end of the support block 11 is provided with a hinge block 23. The hinge seat 211 and the hinge block 23 are hinged by bolts 24 inserted in sequence.

[0033] One side of the hinge block 23 is provided with a toothed surface 231, and one side of the hinge seat 211 is provided with a clearance hole 2111. The bolt 24 slides through the clearance hole 2111. The head of the bolt 24 is provided with a toothed surface 241 that can be separably contacted with the toothed surface 231. The threaded part of the bolt 24 is fitted with a wing nut 242.

[0034] The ruler body 12 has scale lines 121 on its edge. The width of the beam can be observed and measured intuitively through the scale lines 121, and the measured width can be verified at the same time.

[0035] The ruler body 12 has a receiving groove 122 on its side, and the main synchronous pulley 141 and the driven synchronous pulley 142 are both located in the receiving groove 122.

[0036] The inner side of the slider 13 is provided with a pressure block 134 for fixing the timing belt 143, and the pressure block 134 is detachably connected to the slider 13.

[0037] The specific working process of this utility model:

[0038] In use, first adjust the angle between the measuring mechanism 1 and the rod 2 according to the position of the surveyor and the beam to facilitate the measurement operation. For details on the angle adjustment process of the measuring mechanism 1, please refer to [link to relevant documentation]. Figure 5 , Figure 6 Tighten the wing nut 242 to loosen the bolt 24, causing the second toothed surface 241 of the bolt 24 to disengage from the first toothed surface 231 on the hinge block 23. Then, rotate the measuring mechanism 1 to the set angle α via the hinge block 23, and tighten the wing nut 242. The wing nut 242 causes the head of the bolt 24 to slide along the clearance hole 2111. The cross-section of the clearance hole 2111 is consistent with the cross-section of the head of the bolt 24. The clearance hole 2111 limits the bolt 24, preventing the bolt 24 from sliding within the clearance hole 2111, until the first toothed surface 231 passes through the clearance hole 2111 and comes into close contact with the first toothed surface 231 on the hinge block 23. This completes the fixing of the hinge seat 211 and the hinge block 23. The contact between the first toothed surface 231 and the second toothed surface 241 increases the friction between the hinge block 23 and the bolt 24, thereby improving the reliability of the connection between the measuring mechanism 1 and the rod 2.

[0039] After the angle of measuring mechanism 1 is adjusted, the length of rod 2 is adjusted. The specific adjustment process is as follows: loosen the locking ring 221 on the outer tube 22, pull the inner rod 21 out of the outer tube 22 by a certain length, and then tighten the locking ring 221 to complete the adjustment of the length of rod 2.

[0040] After the length of rod 2 is adjusted, hold the end of rod 2 and start the measuring scale using the operation button 72 on the control module 7. Specifically, the control module 7 controls the motor 144 to rotate, which in turn drives the slider 13 to slide to the end away from the support block 11 via the main synchronous pulley 141 and the synchronous belt 143. Then the motor 144 stops, and the support block 11 of the measuring mechanism 1 is placed against one side of the beam, so that the scale 12 is in close contact with the bottom side of the beam. At this time, the operation button 72 controls the motor 144 to rotate in the opposite direction again, and the slider 13 drives the baffle 132 to move to the other side of the beam until the limit switch 133 on the baffle 132 contacts the beam. Limit switch 133 sends a command to control module 7. Control module 7 sends a command to motor 144 to stop running. On the other hand, control module 7 sends commands to laser ranging module 111 and laser ranging module 131. Laser ranging module 111 on support block 11 emits a laser to the surface of the bottom plate above the beam to measure the height h of the beam. At the same time, laser ranging module 131 on slider 13 emits a laser to the side of support block 11 to measure the width b of the beam. The measured height h and width b are then transmitted to control module 7, and finally the measured data are displayed on display screen 71 on control module 7.

[0041] The height of the beam is measured by the laser ranging module 111 on the support block 11, and the width of the beam is measured by the laser ranging module 131 on the slider 13. The measurement data is displayed on the display screen 71. The measurement operation of the measuring ruler is simple and quick, and the measurement accuracy is high. The laser ranging module 111 and the laser ranging module 131 are implemented using existing technology, and will not be described in detail here.

[0042] The measuring mechanism 1 is rotatably connected to the rod 2, and the angle α of the measuring mechanism 1 is locked by the wing nut 242, which makes it more adaptable to measuring beams at different positions. The length of the inner rod 21 can be adjusted, and the inner rod 21 is locked by the locking ring 221 on the outer tube 22, which makes the measuring ruler more adaptable to measuring beams of different heights, thus making the measurement of beams more time-saving, labor-saving, convenient and quick.

[0043] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
