Description

Technical Field

[0001] This utility model belongs to the field of road testing technology, and in particular relates to a road testing and inspection device for road engineering. Background Technology

[0002] The construction phase of road engineering involves testing and inspecting the completed road to ensure that its specifications and performance meet construction requirements. Road testing typically includes compaction testing, pavement thickness testing, smoothness testing, and skid resistance testing. Among these, pavement thickness testing equipment is mainly divided into two types: one is a direct testing device used during construction, and the other is a sampling testing device used after construction is completed. The direct testing device is mainly a calibration measuring ruler. The zero-scale end of the calibration measuring ruler is placed against the unconstructed roadbed, while the calibration plate, which is slidable on the outside of the ruler, overlaps the surface of the constructed roadbed to measure the thickness.

[0003] Chinese patent application CN223307478U discloses a roadbed and pavement thickness detection device, including a lifting plate, a base plate below the lifting plate, a telescopic component between the lifting plate and the base plate, a leveling component on the lower surface of the base plate, a support plate on one side of the base plate, an adjusting component for adjusting the height of the lifting plate between the support plate and the telescopic component, and a detection component between the base plate and the lifting plate. This invention, by setting the adjusting component and the telescopic component, allows for adjusting the length of the detection device. One hand pulls out the second insert rod, and the other hand swings the swing rod clockwise upwards until the clamping groove of the clamping block is below the first insert rod. Pressing down the swing rod uses leverage to lift the first insert rod, the lifting rod, and the lifting plate, raising the lifting plate to a suitable height. The first insert rod is then inserted, restricting the downward movement of the lifting rod and locking the height of the lifting plate to prevent it from being improperly fixed.

[0004] The aforementioned roadbed and pavement thickness detection device mainly consists of a base plate, a lifting plate, an adjustment assembly, multiple insertion rods, and lifting rods. Its structure is numerous and complex, and most parts are metal, making it difficult to carry and transport. Furthermore, each of its four threaded rods has a sleeve at its bottom, with a conical head at the bottom of the sleeve. During use, the sleeve needs to be rotated until the four conical heads are inserted into both the unpaved and paved roadbeds. Unpaved roadbeds have lower hardness and strength, and manual rotation during insertion leads to uncontrollable insertion depth, affecting the accuracy of subsequent test results. Moreover, inserting the conical heads into the roadbed can damage both the unpaved and paved roadbed surfaces. Therefore, we provide a road testing and inspection device for road engineering to solve the aforementioned problems. Utility Model Content

[0014] This utility model has the following beneficial effects: 1. This utility model comprises a mounting plate, a rotating plate, and a fixing assembly. The upper side wall of the mounting plate has a groove, and a rotating shaft is inserted into the outer end of the groove. The mounting plate is rotatably connected to the end of the rotating plate via the rotating shaft. A second plate hole is formed at the left end of the mounting plate, and a rotating sleeve is embedded within the second plate hole. The fixing assembly includes a screw threadedly connected to the rotating sleeve. A rotating handle is fixedly provided at the upper end of the screw, and a fixing element is provided at the lower end. A rod groove is formed on the outer wall of the lower end of the screw, and a rod hole is formed on the inner wall of the rod groove. The fixing assembly includes a fixing sleeve fixed within the rod hole. A short spring and a sliding rod are provided inside the fixing sleeve. The sliding rod is slidably connected to the fixing sleeve via the short spring. A pull rod and a needle-piercing plate are respectively provided at both ends of the sliding rod.

The mounting plate and rotating plate can be rotated and folded. The fixing component and detection component can be removed from the mounting plate and rotating plate, thus achieving the effect of disassembly and carrying. The structure is simple. When the fixed component is lowered onto the unpaved roadbed, it is brought close to the side wall of the already paved roadbed. The pull rod needs to be pulled to compress the short spring. After the bottom of the screw contacts the unpaved roadbed, the pull rod is released. At this time, the short spring returns to its initial state and performs an extension action. The slide rod on the other side of the short spring is pushed, that is, the needle plate on the end of the slide rod contacts the side of the already paved roadbed and hangs on it, thus achieving the effect of fixing. The side hanging method can prevent damage to the upper surface of the road surface.

[0015] 2. This utility model incorporates two detection components, one mounted on the mounting plate and the other on the rotating plate. Each component includes a hollow column and a long spring inside the hollow column. The hollow column is slidably connected to a solid column via the spring. The solid column has an abutment plate on its bottom sidewall and a scale plate embedded in its sidewall. A magnifying glass is embedded in the bottom sidewall of the hollow column. Under the push of the spring, the solid column slides downward and contacts the paved roadbed surface via the abutment plate at its bottom. At this point, the upper end of the scale plate on the solid column enters the hollow column, and the reading can be taken by observing the magnifying glass. The solid column from the other detection component on the mounting plate is then lowered onto the unpaved road surface, and the reading is taken again. The difference between the two readings is the thickness of the roadbed. Attached Figure Description

[0024] Specifically, the upper side wall of the mounting plate 1 is provided with a plate groove 101, and the rotating shaft 202 is rotatably inserted into the end of the plate groove 101.

[0025] Furthermore, the thickness of the plate groove 101 is the same as the thickness of the rotating plate 2.

[0026] Example 2 Please see Figure 3 Based on embodiment 1, a fixing component 3 is also provided. The fixing component 3 is set at the left end of the mounting plate 1. The fixing component 3 includes a screw 301 fixed on the mounting plate 1. A fixing member 303 is provided at the bottom of the screw 301. The fixing member 303 can be moved up and down by the screw 301, which is suitable for roadbed inspection work of different thicknesses. The fixing member 303 includes a fixing sleeve 303a fixed at the bottom of the screw 301. A short spring 303b is provided in the fixing sleeve 303a. The fixing sleeve 303a is connected to the slide rod 303c through the short spring 303b. A pull rod 303e and a needle plate 303d are provided at both ends of the slide rod 303c.

[0027] Specifically, a second plate hole 102 is provided at the left end of the mounting plate 1, and a rotating sleeve 102a is embedded in the second plate hole 102. The screw 301 in the fixing assembly 3 is threadedly connected to the rotating sleeve 102a. A rotating handle 302 is fixedly installed at the upper end of the screw 301. A rod groove 301a is provided at the bottom of the side wall of the screw 301, and a rod hole 301b is provided in the side wall of the rod groove 301a.

[0028] Furthermore, the fixing sleeve 303a is fixedly installed in the rod hole 301b, the rod groove 301a cooperates with the outer peripheral side wall of the needle plate 303d, the slide rod 303c is slidably connected with the fixing sleeve 303a, and the pull rod 303e passes through the outer wall of the fixing sleeve 303a and extends to the outside of the fixing sleeve 303a.

[0029] The operation process of this embodiment is as follows: When in use, hold and rotate the handle 302 to rotate the screw 301. At the same time, the fixing member 303 at the bottom of the screw 301 also moves down until the bottom side wall of the screw 301 contacts the unpaved roadbed. During this process, the pull rod 303e needs to be pulled to compress the short spring 303b. After the bottom of the screw 301 contacts the unpaved roadbed, release the pull rod 303e. At this time, the short spring 303b returns to its initial state and performs an extension action. The slide rod 303c on the other side of the short spring 303b is pushed, that is, the needle plate 303d on the end of the slide rod 303c contacts the side of the paved roadbed and hangs on it.

[0030] Example 3 Please see Figure 4 Based on Embodiments 1 and 2, a detection component 4 is also provided. Two detection components 4 are provided, and they are located in the middle of the mounting plate 1 and the rotating plate 2, respectively.

[0032] Furthermore, an abutment plate 404 is installed on the bottom side wall of the solid column 403. The abutment plates 404 at the bottom of the two solid columns 403 abut against the surface of the paved roadbed and the unpaved roadbed respectively under the action of the long spring 402. A magnifying glass 401a is also embedded in the bottom of the side wall of the hollow column 401.

[0033] The operation process of this embodiment is as follows: First, the solid column 403 is pulled upwards to compress the long spring 402. Then, with the two detection components 4 positioned above the paved and unpaved roadbeds respectively, the solid column 403 is released. At this point, the long spring 402 loses its pulling constraint and returns to its initial state, i.e., it elongates, until the abutment plate 404 at the bottom of the solid column 403 contacts the upper surface of the paved roadbed. At this time, the upper end of the scale plate 403a on the solid column 403 enters the hollow column 401. A reading can be taken by observing through the magnifying glass 401a. Then, the solid column 403 in the other detection component 4 on the mounting plate 1 is lowered onto the unpaved road surface, and the scale plate 403a is read again. The difference between the two readings is the thickness of the roadbed.
