Technical Field
[0001] This utility model relates to the field of road settlement measurement technology, and in particular to a highway settlement measurement device. Background Technology
[0002] Because highway surfaces are frequently subjected to the pressure of vehicles of varying weights, the impact of overloaded or overweight vehicles can cause varying degrees of road surface subsidence and unevenness, necessitating timely repairs to ensure the safety of vehicle traffic. Highways typically consist of multiple layers, including surface layers, subbase layers, and base layers. During actual repairs, measuring tools are required to determine the depth and width of the damage to the roadbed, providing reference data for the excavation depth and width during repairs. However, existing measuring tools are often complex in structure, inconvenient to operate, and lack flexibility.
[0003] For example, a patent for a highway settlement measuring device, published in CN221147589U, describes a device where a moving component moves within a wheel groove, driving a transverse support plate and a mapping component along the highway. Support columns and vertical plates support the mapping board, allowing the mapping component to directly display the measured highway settlement data as a curve on a paper surface for easy viewing. However, even with this method, the settlement curve cannot provide detailed information about the specific settlement after highway damage, offering limited reference material for subsequent repair work. Therefore, there is an urgent need for a highway settlement measuring device that is simple in structure, easy to operate, and capable of measuring both the width and depth of highway settlement zones. Summary of the Invention:
[0004] The technical problem to be solved by this utility model is to provide a highway settlement measurement device, which can measure the width and depth of the highway settlement zone, provide detailed reference data for subsequent repair, and facilitate construction operations.
[0005] The purpose of this utility model is achieved as follows: it includes a longitudinal measuring ruler, a longitudinal receiving groove is provided on the side of the longitudinal measuring ruler, a hinge seat is slidably provided in the receiving groove, the inner end of the horizontal measuring ruler is rotatably connected to the hinge seat, a vertical scale line is provided on one surface of the longitudinal measuring ruler, a horizontal scale line is provided on one surface of the horizontal measuring ruler, and the horizontal measuring ruler can be slidably adjusted along the height direction of the longitudinal measuring ruler.
[0006] It also includes a scale pointer, which is set on the graduated side of the longitudinal measuring scale, with one end of the scale pointer fixed to the hinge seat.
[0007] A spirit level is set on the scale pointer.
[0008] The bottom of the longitudinal measuring ruler has a sliding positioning rod with a pointed tip; that is, the lower end of the positioning rod is tapered, and the positioning rod has scale lines. The tip of the positioning rod is located on the longitudinal center line of the longitudinal measuring ruler.
[0009] The lower surface of the longitudinal measuring ruler has a mounting hole that is recessed into the longitudinal measuring ruler for the positioning rod to slide through. The lower side wall of the longitudinal measuring ruler has a groove that communicates with the mounting hole. A slider is connected to the positioning rod. The slider is slidably disposed in the groove and its outer end protrudes from the groove. By sliding the slider, the positioning rod can be moved in the mounting hole at the bottom of the longitudinal measuring ruler.
[0010] An end plate is fixed to the end of the slider exposed outside the slide groove. The width of the end plate is greater than the width of the slide groove. A locking bolt is set on the end plate at the position of the longitudinal measuring scale on the outside of the slide groove. Tightening the locking bolt is to limit the position of the adjusted positioning rod.
[0011] The aforementioned horizontal measuring ruler includes a receiving sleeve. The horizontal scale lines on the aforementioned horizontal measuring ruler are set on the outer surface of the receiving sleeve. A guide groove is provided through the top wall of the receiving sleeve along its length. A measuring plate with scale is slidably arranged inside the receiving sleeve. A protruding guide block is provided on the top of the measuring plate near the longitudinal measuring ruler. The guide block is slidably arranged in the guide groove.
[0012] The outer end of the accommodating sleeve has an opening, and the outer end of the measuring plate is fixed with a limiting plate. The limiting plate is located outside the opening at the outer end of the accommodating sleeve, and a rectangular opening is provided on the limiting plate.
[0013] The lower surface of the accommodating sleeve has a through groove that communicates with its interior. The bottom of the measuring plate is located in the through groove, and its lower surface is flush with the lower surface of the accommodating sleeve.
[0014] The housing contains a retractable measuring tape, controlled by a spring similar to that used in measuring tapes. The measuring tape has graduations. A shaft is located near the longitudinal measuring scale within the housing, rotatably connected to the housing. The measuring tape is wound around the shaft, which is fixed to a ratchet. A ratchet tooth, elastically fitted within the housing, engages with the ratchet. A rotating rod is mounted on the ratchet tooth, its tip extending out of the housing and connected to an adjusting cap. The outer end of the measuring tape extends from a rectangular opening in a limiting plate. A downward-extending vertical plate is fixed to the end of the measuring tape outside the rectangular opening, with its lower surface below the lower surface of the rectangular opening. In other words, the measuring tape extends outward from the housing along the measuring plate, and is positioned below the graduations on the measuring plate.
[0015] The top of the adjusting cap is also fitted with a spirit level, which is used to measure the position of the level measuring ruler.
[0016] The beneficial effects of this utility model are as follows: the longitudinal measuring ruler enables the measurement of the depth of the settlement zone; the horizontal measuring ruler enables the measurement of the width of the settlement zone, providing data reference for excavation operations during subsequent repairs; the adjustable length of the horizontal measuring ruler can meet various settlement zone measurement operations, expanding the applicability of this device; the retractable and adjustable horizontal measuring ruler reduces the space occupied during storage and transportation, enhancing the practicality of this device.

[0018] Figure 2 yes Figure 1 Enlarged structural diagram at point A;
[0019] Figure 3 This is a schematic diagram of the structure of the horizontal measuring ruler in this utility model. Detailed Implementation
[0020] The following is combined Figure 1-3 The present invention will be further described below;
[0021] It includes a longitudinal measuring ruler 1, with a longitudinal receiving groove 2 on the side of the longitudinal measuring ruler, and a hinge seat 3 slidably disposed in the receiving groove. The inner end of the horizontal measuring ruler 4 is rotatably connected to the hinge seat. A vertical scale line 5 is provided on one surface of the longitudinal measuring ruler, and a horizontal scale line 6 is provided on one surface of the horizontal measuring ruler. The horizontal measuring ruler can be slidably adjusted along the height direction of the longitudinal measuring ruler so that during measurement, the position of the horizontal measuring ruler can be adjusted vertically so that the outer end of the horizontal measuring ruler is placed on a flat ground outside the settlement zone, ensuring the accuracy of the measurement.
[0022] After use, the level measuring ruler can be folded up and stored in the receiving slot to reduce the amount of external space occupied.
[0023] It also includes a scale pointer 7, which is set on the graduated side of the longitudinal measuring ruler. One end of the scale pointer is fixed on the hinge seat, and the scale pointer can move with the movement of the hinge seat to indicate the collapse depth measured by the longitudinal measuring ruler, making it convenient to read the data. Since the longitudinal measuring ruler is usually placed in the settlement zone during the measurement work, and the horizontal measuring ruler is adjusted to the working state so that its bottom is attached to the flat ground outside the settlement zone, the scale line indicated by the scale pointer at this time is the depth at the corresponding measurement position in the settlement zone.
[0024] A bubble level 8 is set on the scale pointer to ensure that the position of the longitudinal measuring ruler does not deviate during measurement, thereby reducing measurement error.
[0025] The bottom of the longitudinal measuring scale is equipped with a slidable positioning rod 9 with a pointed tip. The lower end of the positioning rod is tapered, and it has graduations. The tip of the positioning rod is located on the longitudinal center line of the longitudinal measuring scale. This positioning rod facilitates the positioning of the longitudinal measuring scale in uneven areas within the settlement zone. Since there are usually few flat surfaces inside the settlement zone, the pointed positioning rod allows for proper positioning of the longitudinal measuring scale during measurement. The positioning rod does not need to be inserted into the settlement zone during use; simply ensuring the longitudinal measuring scale is vertical by pointing the tip towards the bottom of the settlement zone is sufficient. Therefore, the graduations on the positioning rod facilitate the totaling of the height of the protruding bottom of the positioning rod during measurement, reducing measurement errors.
[0026] The lower surface of the longitudinal measuring ruler has a mounting hole that is recessed into the longitudinal measuring ruler for the positioning rod to slide through. The lower side wall of the longitudinal measuring ruler (i.e. the side with vertical scale lines) has a groove 10 that communicates with the mounting hole. A slider 11 is connected to the positioning rod. The slider is slidably disposed in the groove and its outer end protrudes from the groove. By sliding the slider, the positioning rod can be moved in the mounting hole at the bottom of the longitudinal measuring ruler.
[0027] An end plate 12 is fixed to the end of the slider exposed outside the slide groove. The width of the end plate is greater than the width of the slide groove. A locking bolt 13 is provided on the end plate at the position of the longitudinal measuring scale corresponding to the outside of the slide groove. Tightening the locking bolt is to limit the position of the adjusted positioning rod and ensure its stability during operation.
[0028] The horizontal measuring ruler includes a housing sleeve 14. The horizontal scale lines on the horizontal measuring ruler are set on the outer surface of the housing sleeve. A guide groove 15 is provided through the top wall of the housing sleeve along its length. A measuring plate 16 with scale is slidably arranged inside the housing sleeve. A protruding guide block 17 is provided on the top of the end of the measuring plate near the longitudinal measuring ruler. The guide block is slidably arranged in the guide groove to ensure the stability of the measuring plate when it slides.
[0029] The outer end of the accommodating sleeve has an opening, and the outer end of the measuring plate is fixed with a limiting plate 18. The limiting plate is located outside the opening at the outer end of the accommodating sleeve, and a rectangular opening 19 is provided on the limiting plate. The rectangular opening is designed to provide a gripping space for pulling the measuring plate to move, thereby improving the convenience of operation.
[0030] The measurement distance in the horizontal direction can be extended by sliding out the measuring plate (i.e., the length on the horizontal measuring ruler and the length on the slid-out measuring plate are added together), which can meet the measurement needs of different settlement zones.
[0031] The lower surface of the accommodating sleeve has a through groove that communicates with its interior. The bottom of the measuring plate is located in the through groove, and its lower surface is flush with the lower surface of the accommodating sleeve to ensure that the lower surfaces of the two are on the same horizontal plane during use.
[0032] A retractable measuring tape 20 is installed inside the housing. The measuring tape is controlled by a spring similar to that of a measuring tape. The measuring tape has graduations. A shaft 21 is located near the longitudinal measuring scale inside the housing, rotatably connected to the housing. The measuring tape is wound around the shaft, which has a ratchet 22 fixed thereon. A ratchet tooth 23, elastically fitted inside the housing, engages with the ratchet. A rotating rod 24 is mounted on the ratchet tooth, with its top end extending out of the housing and connected to an adjusting cap 25. The outer end of the measuring tape extends from a rectangular opening 19 in the limiting plate. A downward-extending upright plate 26 is fixed to the end of the measuring tape outside the rectangular opening, with its lower surface below the lower surface of the rectangular opening. This prevents the upright plate from entering the housing through the rectangular opening. In other words, the measuring tape extends outward along the measuring plate inside the housing, and is located below the graduations on the measuring plate. When the measuring tape is not needed to extend the measuring distance, the upright plate rests against the limiting plate.
[0033] The ratchet and ratchet mechanism ensures that the measuring belt can be pulled out smoothly, but it cannot reset itself. This allows for positioning of the pulled-out measuring plate. To reset the measuring plate, simply rotate the adjusting cap to disengage the ratchet from the ratchet.
[0034] In addition, a spirit level is also embedded at the top of the adjusting cap, which is used to measure the position of the level measuring ruler, ensure its levelness, and reduce measurement errors.
[0035] The measuring belt can be extended and retracted. The measuring belt can extend the measuring length of the horizontal measuring ruler and further expand the measuring range of this measuring device. Since the depth of the settlement zone is usually fixed, but the width varies greatly, by setting a stretchable and retractable measuring belt, when the width of the settlement zone is large, the measuring plate can be released from the housing sleeve and the measuring belt can continue to be stretched and extended, thus increasing the measuring range.
[0036] When using this device, first place the longitudinal measuring ruler within the settlement zone, typically at the deepest point, to determine the maximum excavation depth of the roadbed during repair. Simultaneously, unfold the horizontal measuring ruler horizontally and move the measuring plate so that its bottom is positioned on the road surface on both sides outside the settlement zone. The data indicated by the pointer on the longitudinal measuring ruler at this point represents the depth of the settlement zone. By adding the data from the horizontal measuring ruler to the width of the longitudinal measuring ruler, the width of the settlement zone on one side of the longitudinal measuring ruler can be obtained. After measurement, the horizontal measuring ruler can be stored away to reduce space occupation. The device has a simple structure, is easy to operate, and is highly practical.
[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
