Description

Technical Field

[0001] This utility model relates to the field of highway construction thickness detection technology, and in particular to a highway construction thickness detection sampler. Background Technology

[0002] Highway construction involves many aspects, such as the detection of concrete thickness on the highway pavement. During highway construction, ensuring that the thickness of each layer of material meets the design requirements is crucial, as it directly affects the quality and service life of the highway.

[0003] Currently, when measuring pavement thickness during highway construction, manual measurement tools such as rulers are typically inserted into the uncured concrete pavement to determine the thickness. However, this method has certain drawbacks. The angle at which the measuring tool is inserted is prone to tilting, which reduces the accuracy of the thickness measurement data. Furthermore, common measuring tools are not convenient for sampling concrete in the underlying areas, making them impractical. Therefore, we propose a highway construction thickness measurement sampler. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies. Currently, when detecting the thickness of a road surface during highway construction, it is usually done manually by inserting measuring tools such as rulers into the uncured concrete pavement to determine the thickness. However, this method has certain drawbacks. The angle at which the measuring tools are inserted is prone to tilting, which leads to a decrease in the accuracy of the thickness detection data. Furthermore, common measuring tools are not convenient for sampling concrete in the underlying areas, making them impractical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A highway construction thickness detection sampler includes a sampling mechanism, and a support mechanism is sleeved around the sampling mechanism near its top.

[0007] The sampling mechanism includes a sampling tube, a sampling chamber is provided inside the sampling tube near the bottom, a window is provided on the left side of the sampling tube corresponding to the sampling chamber, a connecting rod is rotatably connected inside the sampling tube, a baffle is fixedly connected to one end of the connecting rod near the bottom and inside the sampling chamber, and a scale is engraved on the outer periphery of the sampling tube.

[0008] The support mechanism includes a sleeve that is fitted around the sampling cylinder, and several support components are equidistantly ringed around the outer periphery of the sleeve near the top.

[0009] As a preferred embodiment of this utility model, handles are symmetrically installed on the left and right sides of the sampling tube near the top.

[0010] The technical advantage of adopting the above-mentioned further solution is that the handle makes it easy for users to press the sampling tube and insert its bottom end into the concrete pavement for sampling, thus improving the ease of use.

[0011] As a preferred embodiment of this utility model, a limiting ring is welded to the periphery of the sampling cylinder and at the top of the sleeve.

[0012] The technical effect of adopting the above-mentioned further solution is that the limiting ring can prevent the user from pressing the sampling cylinder excessively, thereby protecting the slider and preventing the slider from breaking off from the sampling cylinder.

[0013] As a preferred embodiment of this utility model, a guide rail is provided around the inner top of the sampling chamber near the outer perimeter, and the baffle is slidably connected to the guide rail.

[0014] The technical effect of adopting the above-mentioned further solution is that the sliding connection between the baffle and the guide rail can limit the rotation of the baffle, prevent it from deviating, and improve the stability of use.

[0015] As a preferred embodiment of this utility model, the baffle is a semi-circular arc-shaped metal structure.

[0016] The technical effect of adopting the above-mentioned further solution is that the semi-circular arc-shaped metal structure baffle can fit more closely to the inner wall of the sampling cylinder, thereby improving the sealing effect of the window.

[0017] As a preferred embodiment of this utility model, the sleeve has symmetrically formed grooves on the left and right sides inside, and a slider is slidably connected inside the groove, and the slider is fixedly connected to the sampling cylinder.

[0018] The technical effect of adopting the above-mentioned further solution is that by fixing the slider to the sampling cylinder, the moving sampling cylinder can be limited, preventing the insertion angle from shifting and improving the stability of use.

[0019] As a preferred embodiment of this utility model, the support assembly includes a support rod, which is welded to the sleeve. An adjusting rod is slidably connected to the top end of the support rod away from the sleeve, passing through the bottom. A threaded rod is rotatably connected to the end of the support rod away from the sleeve.

[0020] The technical effect of adopting the above-mentioned further solution is that by sliding different adjusting rods, the horizontal posture of the sleeve can be adjusted according to the degree of potholes in the road surface, thereby preventing the sampling tube from tilting when inserted. By rotating the threaded rod to make it contact the adjusting rod, the adjusting rod can be fixed to prevent it from loosening.

[0021] As a preferred embodiment of this utility model, the end of the adjusting rod near the bottom has a tapered structure.

[0022] The technical effect of adopting the above-mentioned further solution is that the tapered structure at the bottom of the adjusting rod allows the adjusting rod to be inserted more smoothly into the uncured concrete pavement, improving ease of use.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, the design of the sampling mechanism and the support mechanism allows for the adjustment of the horizontal position of the sleeve by sliding different adjustment rods, based on the smoothness of the road surface. This prevents the sampling tube from tilting during insertion, improving detection accuracy. A scale is also used to detect the road surface thickness. After the sampling tube is inserted into the road surface, the linkage rod is rotated, causing the baffle to rotate and become misaligned with the window, allowing concrete to flow into the sampling chamber and completing the sampling process. This effectively improves practicality. Attached Figure Description

[0034] Example 1

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a highway construction thickness detection sampler, including a sampling mechanism 1, a support mechanism 2 sleeved around the sampling mechanism 1 near the top, the sampling mechanism 1 including a sampling cylinder 101, a sampling chamber 102 opened inside the sampling cylinder 101 near the bottom, a window 103 opened on the left side of the sampling cylinder 101 corresponding to the sampling chamber 102, a connecting rod 104 rotatably connected inside the sampling cylinder 101, a baffle 105 fixedly connected at one end of the connecting rod 104 near the bottom and inside the sampling chamber 102, a scale 106 engraved on the outer periphery of the sampling cylinder 101, and a sleeve 201 sleeved around the outer periphery of the sampling cylinder 101, with a plurality of support components 202 equidistantly ring-mounted around the outer periphery of the sleeve 201 near the top.

[0036] Example 2

[0037] like Figure 1-4As shown, handles 1011 are symmetrically installed on the left and right sides of the sampling cylinder 101 near the top. The handles 1011 facilitate user pressing of the sampling cylinder 101 to insert its bottom end into the concrete pavement for sampling, improving ease of use. A limit ring 1012 is welded to the outer periphery of the sampling cylinder 101 and to the top of the sleeve 201. The limit ring 1012 prevents excessive pressure on the sampling cylinder 101, thus protecting the slider 2012 and preventing it from detaching from the sampling cylinder 101. The inner top of the sampling chamber 102 is near the outer periphery... A guide rail 1021 is provided around the perimeter, and a baffle 105 is slidably connected to the guide rail 1021. This slidable connection between the baffle 105 and the guide rail 1021 limits the rotation of the baffle 105, preventing it from shifting and improving stability. The baffle 105 is a semi-circular arc-shaped metal structure, which allows it to fit more closely to the inner wall of the sampling cylinder 101, thus improving the sealing effect on the window 103. The sleeve 201 has symmetrically provided grooves 2011 near the left and right sides inside. The internal sliding connection includes a slider 2012, which is fixedly connected to the sampling cylinder 101. This fixed connection limits the movement of the sampling cylinder 101, preventing deviations in the insertion angle and improving stability. The support assembly 202 includes a support rod 2021, which is welded to the sleeve 201. An adjusting rod 2022 is slidably connected to the top end of the support rod 2021 (away from the sleeve 201) through the bottom. A threaded rod is rotatably connected to the end of the support rod 2021 (away from the sleeve 201). 2023, by sliding different adjusting rods 2022, the horizontal posture of the sleeve 201 can be adjusted according to the degree of potholes in the road surface, thereby preventing the sampling cylinder 101 from tilting when inserted. By rotating the threaded rod 2023 to make it contact the adjusting rod 2022, the adjusting rod 2022 can be fixed to prevent it from loosening. The end of the adjusting rod 2022 near the bottom has a tapered structure. Through the tapered structure at the bottom of the adjusting rod 2022, the adjusting rod 2022 can be inserted into the uncured concrete road surface more smoothly, improving the ease of use.

[0038] The working process of this utility model is as follows: When using a road construction thickness detection sampler for road surface thickness detection and sampling, firstly, the support mechanism 2 is placed above the road surface to be detected, and the bottom end of the adjusting rod 2022 is inserted into the bottom layer of the road surface. The adjusting rod 2022 is slid according to the degree of potholes in the bottom layer of the road surface, thereby adjusting the horizontal position of the sleeve 201 so that the sampling cylinder 101 is perpendicular to the road surface. Then, the threaded rod 2023 is rotated so that its spiral is submerged inside the support rod 2021, clamping and fixing the adjusting rod 2022 to prevent it from slipping during use. If loosening occurs, pressing the handle 1011 will move the sampling cylinder 101 inside the sleeve 201. The slider 2012 will slide downwards through the sliding relationship between the slider and the groove 2011, thus inserting the sampling cylinder 101 into the road surface until the bottom of the sampling cylinder 101 contacts the bottom layer of the road surface. The thickness data of the road surface can be obtained by observing the scale 106. Then, rotating the connecting rod 104 will cause the baffle 105 to rotate inside the guide rail 1021 and be misaligned with the window 103, allowing concrete to flow into the sampling chamber 102, completing the sampling and effectively improving practicality.

[0039] 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.
