Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically an integrated measuring device for municipal road surveying. Background Technology

[0002] Municipal roads are an important part of urban infrastructure. They refer to public roads within the urban planning area that are constructed and managed by relevant government departments. These roads are mainly used to meet the daily travel needs of urban residents, including motor vehicle lanes, non-motor vehicle lanes, and sidewalks. They also undertake functions such as urban traffic management and public transportation operation. The construction and maintenance of municipal roads are of great significance to ensuring the normal operation of the city, promoting economic development, and improving the quality of life of residents.

[0003] The slope survey of municipal roads is essential, as slope directly affects road drainage performance. A reasonable slope design can effectively guide rainwater to drain quickly, preventing traffic safety hazards and road damage caused by water accumulation. From a traffic engineering perspective, slope also affects vehicle performance and driving comfort. Excessive slope increases vehicle energy consumption and braking distance, while insufficient slope can lead to poor drainage. Therefore, in the construction of municipal roads, slope measurement devices are needed to survey the road slope to ensure the scientific and rational design of the road.

[0004] During the construction layout phase, a slope gauge is needed to measure the slope of the road to ensure that construction workers can accurately construct according to the design requirements. This includes measuring and adjusting the slope of the subgrade, pavement base layer and surface layer to ensure construction quality.

[0005] In the early stages of municipal road construction, when using a slope gauge for slope surveying, the limited measuring range of the slope gauge often necessitates multiple measurements and data splicing to obtain complete slope information. However, before each measurement, the level tube inside the slope gauge needs to be adjusted to ensure measurement accuracy. Existing adjustment methods typically involve rotating the operating handle, using a mechanical structure to control the rotation of the level tube. This adjustment method is cumbersome in the early stages of construction where frequent measurements are required and is difficult to adapt to the needs of multiple measurements. Therefore, to address the above problems, an integrated measuring device for municipal road surveying is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Please see Figures 1-8 This utility model provides a technical solution:

[0033] An integrated measuring device for municipal road surveying includes a housing assembly 1. An operating assembly 2 is located near the upper end of the housing assembly 1. A measuring assembly 3 is rotatably connected to the inner side of the housing assembly 1. The housing assembly 1 includes a ruler shell 11 and an inner ring shell 12. Permanent magnet blocks 13 are fixedly connected to both sides of the inner ring shell 12. A receiving groove 14 is opened inside the permanent magnet block 13. Two sealing airbag rings 15 are fixedly connected to the inner side of the receiving groove 14. A diversion hole 16 is opened inside the receiving groove 14. A branching channel 17 and a column square groove 18 are opened inside the ruler shell 11. The measuring assembly 3 includes a ring cylinder 31. Extension rods 34 are fixedly connected to both sides of the ring cylinder 31. An extension seat 35 is fixedly connected to the bottom end of the extension rod 34. A counterweight iron column 36 is rotatably connected to the inner side of the extension seat 35. The outer side of the ring cylinder 31 is rotatably connected to the inner side of the receiving groove 14 through a ball bearing 19. The sealing airbag rings 15 can fit against the outer side of the ring cylinder 31 after expansion.

[0034] As a further implementation of this scheme, the branch channel 17 is connected to the columnar groove 18. The columnar groove 18 is cylindrical in shape near the front half. The branch channel 17 is provided with two branches and is connected to two diversion holes 16. Through the above arrangement, this design provides a stable channel for gas flow, allowing gas to flow smoothly through the branch channel 17 and the diversion holes 16 inside the device, ensuring that the device can respond quickly during the adjustment process.

[0035] As a further implementation of this solution, the operating component 2 includes an operating handle 21. A screw 22 is fixedly connected to the front end of the operating handle 21. A limiting ring 23 is fixedly connected to the outside of the screw 22. Multiple ventilation holes are opened on the inner side of the limiting ring 23. The limiting ring 23 is rotatably connected to the inside of the columnar groove 18 opened in the housing 11. With the above settings, after operating the operating handle 21, the internal threaded cylinder 24 can be controlled to move back and forth, so that the internal threaded cylinder 24 slides inside the columnar groove 18. The design of the ventilation holes inside the limiting ring 23 allows external air to circulate through the gap between the internal threaded cylinder 24 and the columnar groove 18 and the ventilation holes, ensuring the effectiveness of the back and forth movement of the internal threaded cylinder 24.

[0036] As a further implementation of this solution, the screw 22 is spirally connected to the threaded hole of the internal threaded cylinder 24. A rubber sealing ring 26 is fixedly connected to the internal threaded cylinder 24 near the front end, and a guide block 25 is fixedly connected to the internal threaded cylinder 24 near the rear end. The rubber sealing ring 26 is located in the front half of the column square groove 18, and the guide block 25 is slidably connected to the inside of the column square groove 18. The outer side of the rubber sealing ring 26 is in contact with the inner side of the column square groove 18. Through the above settings, the movement of the internal threaded cylinder 24 and the rubber sealing ring 26 is controlled, thereby achieving the effect of filling and evacuating the gas inside the sealing airbag ring 15, and achieving the effect of controlling the rotation and fixation of the ring cylinder 31. This eliminates the need for frequent adjustment of the ring cylinder 31 during measurement, improving the convenience of use.

[0037] As a further implementation of this solution, two sealing airbag rings 15 are distributed at the left and right ends of the ball bearing 19. The inner side of the sealing airbag ring 15 is connected to the diversion hole 16. Through the above arrangement, the gas inside the sealing airbag ring 15 can be connected to the inside of the column groove 18 through the diversion hole 16 and the bifurcation channel 17. After the sealing airbag ring 15 expands, it can seal the inside of the receiving groove 14 to prevent dust from damaging the ball bearing 19.

[0038] As a further implementation of this scheme, a horizontal tube 32 is fixedly connected to the middle of the ring cylinder 31, and a pointer 33 is fixedly connected to the upper part of the ring cylinder 31. The pointer 33 points to the scale opened in the inner ring shell 12. Through the above settings, the structural design of the ring cylinder 31, the horizontal tube 32 and the pointer 33 enables the pointer 33 to accurately point to the inner ring shell 12 of the scale, ensuring the intuitiveness and accuracy of the measurement results.

[0039] As a further implementation of this solution, the counterweight column 36 and the permanent magnet block 13 are magnetically attracted to each other. An extension block is provided at the upper end of the counterweight column 36, and the extension block of the counterweight column 36 is embedded in the extension rod 34. Through the above-mentioned arrangement, the magnetic attraction design between the counterweight column 36 and the permanent magnet block 13 can effectively suppress the inertial swing of the ring cylinder 31, significantly shorten the time for the pointer 33 to reach a stationary state, and thus quickly provide stable measurement data.

[0040] Workflow: In preparation for measurement, hold the handle of the scale housing 11. At this time, the ring cylinder 31 needs to be unlocked. By operating the lever 21, the screw 22 and the limiting ring 23 are rotated. The limiting ring 23 is rotated and connected to the inside of the columnar groove 18 opened in the scale housing 11. It is connected to the internal threaded cylinder 24 through the screw 22. At this time, the internal threaded cylinder 24 will move backward under the limitation of the guide block 25. Since the internal threaded cylinder 24 is sealed to the inside of the columnar groove 18 by the rubber sealing ring 26, this sealing state can control the gas flow, and thus achieve a suction effect. The gas inside the sealing airbag ring 15 enters the column groove 18 through the diversion hole 16 and the bifurcation channel 17. When the gas inside the sealing airbag ring 15 is removed, the sealing airbag ring 15 will become deflated. In this way, the sealing airbag ring 15 will be far away from the ring cylinder 31. By controlling the shape of the sealing airbag ring 15, not only can the ring cylinder 31 be fixed inside the receiving groove 14, but it can also form a seal inside the receiving groove 14. This prevents dust from entering the receiving groove 14 during carrying, thereby protecting the ball bearing 19.

[0041] When measuring the slope, the measuring tape 11 is placed on a municipal road. After the sealing airbag ring 15 detaches from the ring cylinder 31, the counterweight iron column 36, under the influence of gravity and the earth's gravitational pull, will cause the ring cylinder 31 to rotate via the extension rod 34 and extension seat 35. The ring cylinder 31 rotates inside the receiving groove 14 via the ball bearing 19. The weight of the counterweight iron column 36 is three times the magnetic attraction between the counterweight iron column 36 and the permanent magnet block 13. The magnetic attraction between the counterweight iron column 36 and the permanent magnet block 13 can control the ring cylinder 31 to swing back and forth due to inertia. Through the magnetic attraction between the permanent magnet block 13 and the counterweight iron column 36, the resistance of the ring cylinder 31 during rotation can be increased, thereby significantly increasing the stationary speed of the ring cylinder 31. To ensure the speed of measurement data, and to prevent the weight of the counterweight column 36 from remaining stationary due to the magnetic attraction between the counterweight column 36 and the permanent magnet block 13, the counterweight column 36 is effectively oriented downwards. Simultaneously, the rotational coordination between the counterweight column 36 and the extension rod 34 allows the counterweight column 36 to remain oriented towards the Earth's center even when the device is not perpendicular to the ground. This ensures that the counterweight column 36 can still drive the ring cylinder 31 to rotate. The stationary state of the ring cylinder 31 is determined by observing whether the water level inside the horizontal pipe 32 is fluctuating. Data is recorded by observing the pointer 33 pointing to the scale on the inner ring shell 12. By integrating data from multiple measurements, the average value of all measurement points can be calculated.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
