Description

Technical Field

[0001] This application relates to the technical field of road marking detection, and particularly relates to a road marking sampling device. Background Art

[0002] On roads, reflective coatings are usually used to spray different markings on the road surface so that vehicles can identify information such as lanes when driving. Reflective markings can reflect the light of car headlights in rainy or nighttime conditions, so that drivers can still effectively identify the markings when visibility is poor. Therefore, the reflective performance of road markings is an important indicator. The current sampling inspection requirement is to conduct inspections at 3 to 5 locations per 10 km. During the inspection, the inspection personnel place the sampling plate on the road surface at the starting point or the end point of the marking position. When the line marking vehicle passes by, it makes a mark on the road surface and the sampling plate, then takes away the sampling plate, and then simulates the rainy night environment for the marking on the sampling plate in the laboratory, and measures the light emission parameters through instruments. Existing line marking vehicles mainly make marks on the ground by spraying. During sampling, the sampling plate is often affected by the spraying air flow and paint impact, resulting in the displacement of the sampling plate, so that a complete marking cannot be obtained. Therefore, a road marking sampling device is needed that can fix the sampling plate by its own weight during sampling to prevent the sampling plate from shifting, thereby improving the success rate and quality of sampling. Content of the Utility Model

[0003] To solve the above problems, this application proposes a road marking sampling device that can fix the sampling plate by its own weight during sampling to prevent the sampling plate from shifting, thereby improving the success rate and quality of sampling.

[0004] This application is achieved through the following technical solutions:

Universal wheels are provided at the four lower corners of the bottom plate, and a connecting rod is provided on the side of the bottom plate; one end of the extension rod is provided with a connecting seat, and the other end of the extension rod is connected to the connecting sleeve through a universal ball joint; the lower part of the connecting seat is connected to the extension rod, the upper part of the connecting seat is hinged to the connecting rod through a first bolt, and a locking nut is provided on the first bolt; the sampling plate is placed on the ground, and one side of the sampling plate is connected to the connecting sleeve.

[0006] Further, a ferrous protrusion is provided on one side of the sampling plate, a blind hole is provided in the lower part of the connecting sleeve, the inner diameter of the blind hole is the same as the outer diameter of the protrusion, and a magnet is provided at the bottom of the blind hole.

[0010] Further, side baffles and a push handle are provided on the bottom plate.

[0011] Further, a brake pedal is provided on the universal wheel.

[0012] Advantages of the present application: By providing an extension rod on the bottom plate, the extension rod is connected to the connecting sleeve through a universal ball joint. After the sampling plate is placed, it can be connected to the sampling plate through the connecting sleeve.

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0020] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0021] As Figures 1 to 4 shown, an embodiment of the present utility model provides a road marking sampling device, including: a bottom plate 1, a sampling plate 2, an extension rod 3, and a connecting sleeve 9. Universal wheels 4 are provided at the four corners of the lower part of the bottom plate 1, and a connecting rod 5 is provided on the side of the bottom plate 1; one end of the extension rod 3 is provided with a connecting seat 6, and the other end of the extension rod 3 is connected to the connecting sleeve 9 through a universal ball joint 8; the lower part of the connecting seat 6 is connected to the extension rod 3, and the upper part of the connecting seat 6 is hinged to the connecting rod 5 through a first bolt, and a locking nut 7 is provided on the first bolt; the sampling plate 2 is placed on the ground, and one side of the sampling plate 2 is connected to the connecting sleeve 9.

[0022] When sampling, place the sampling plate 2 at the starting or ending position of the road marking. Then, push the device near the sampling plate 2 through the push handle 15, step on the brake pedal of the universal wheel 4 to lock the universal wheel 4, and after connecting the connecting sleeve 9 with the protrusion 10, correct the position of the sampling plate 2 so that the path of the marking exactly passes through the middle of the sampling plate 2. After the adjustment is completed, tighten the seventh, second bolt 11, and third bolt 13 to limit the movement of the extension rod 3 and the universal ball joint 8, so that the sampling plate 2 is fixedly connected to the bottom plate 1. When the line marking vehicle is marking, the reflective paint is ejected by the high-pressure air flow to achieve road marking. After the line marking vehicle passes the sampling plate 2, the reflective paint is sprayed on the sampling plate 2. Structures such as the extension rod 3 and the connecting seat 6 provide support force for the sampling plate 2 to prevent the sampling plate 2 from shifting caused by the air flow and paint during line change, ensuring that the line marking vehicle accurately sprays the reflective marking on the sampling plate 2, thereby improving the success rate and quality of sampling.

[0023] In a preferred embodiment, as Figure 2 shown, one side of the sampling plate 2 is provided with an iron protrusion 10. The lower part of the connecting sleeve 9 is provided with a blind hole. The inner diameter of the blind hole is the same as the outer diameter of the protrusion 10, and a magnet is provided at the bottom of the blind hole. The protrusion 10 is adsorbed in the blind hole of the connecting sleeve 9 by the magnet. The magnet uses a rare earth magnet to ensure that there is enough adsorption force to adsorb the protrusion 10 in the blind hole of the connecting sleeve 9, thereby limiting the sampling plate 2 through the connecting sleeve 9 and the protrusion 10 to prevent the sampling plate 2 from shifting during sampling.

[0024] Preferably, as Figure 3 shown, two second bolts 11 are provided at the lower part of the connecting seat 6, and an oblong hole is provided on the extension rod 3. The second bolts 11 pass through the oblong hole, and the second bolts 11 are connected to the extension rod 3 through gaskets and nuts. When the nuts are loosened, the connecting seat 6 can slide along the extension rod 3, thereby adjusting the elongation distance of the extension rod 3 to meet the use requirements of different sites.

[0025] Specifically, a handle 12 is provided on the locking nut 7. The handle 12 is connected to the outer circumference of the locking nut 7 along the radial direction. The handle 12 facilitates tightening the locking nut 7 by extending the force arm. After the locking nut 7 is tightened, it can clamp the extension rod 3 and the connecting seat 6 to prevent the extension rod 3 from swinging, achieving the purpose of limiting the sampling plate 2.

[0026] In a specific embodiment, as Figure 3 shown, the universal ball joint 8 includes an outer ball and an inner ball. The outer ball wraps the upper part of the inner ball. The outer ball and the inner ball are respectively connected to the extension rod 3 and the connecting sleeve 9 through connecting rods. The inner ball can rotate in the outer ball, so as to have different orientations, meeting the connection requirements when the road surface is uneven. And a third bolt 13 is provided on the outer ball. The end of the third bolt 13 passes through the outer ball and presses against the outer circumference of the inner ball. After the third bolt 13 is tightened, the inner ball can be fixed in the outer ball to prevent the universal ball joint 8 from loosening.

[0027] In a specific embodiment, as Figure 1 shown, a side baffle 14 and a push handle 15 are provided on the bottom plate 1. The sampling plate 2 can be placed in the space enclosed by the side baffle 14 and the bottom plate 1 to increase the weight of the device, thereby improving the stability of the sampling plate 2 during sampling. The push handle 15 facilitates the movement of the device.

[0028] In a specific embodiment, a brake pedal is provided on the universal wheel 4. The universal wheel 4 uses a commercially available universal wheel 4 with a braking function. After the brake pedal is depressed, the universal wheel can be locked, thereby restricting the rotation of the universal wheel 4 and keeping the device stationary, so as to keep the sampling plate 2 stable by the self-weight of the device.

[0029] Of course, the present application may also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present application.
