Description

Technical Field

[0001] This utility model relates to the technical field of traffic marking measurement equipment, and in particular to a road traffic marking thickness measurement and marking device. Background Technology

[0002] Traffic markings, as an important road infrastructure, play a crucial role in separating and guiding traffic flow, improving traffic efficiency, and ensuring traffic safety. Their thickness directly affects wear resistance, visibility, and service life, making them a key parameter for evaluating the performance of traffic markings.

[0003] Therefore, after the road traffic markings are completed, the road markings need to be sampled and tested. Currently, the commonly used equipment for testing the thickness of the markings is digital calipers and coating thickness gauges. The drawbacks are that manual measurement requires repeated bending over, which is labor-intensive and has low measurement efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road traffic marking thickness measurement and marking device, which solves the problem of low efficiency in existing road traffic marking thickness measurement devices.

The bottom of the housing is provided with wheels and a mounting groove. The slide rail is horizontally fixed to the top of the mounting groove by a connecting rod. The bottom of the slide rail is provided with a first sliding groove. There are at least two laser rangefinders. Each laser rangefinder is slidably mounted in the first sliding groove by a mounting component. Each mounting component has a fastening component on one side for locking the laser rangefinder in the first sliding groove. A crossbar is provided on the side wall of the slide rail. A marking pen is provided at the bottom of the crossbar by a connecting component.

[0006] Compared with existing technologies, this utility model has the following advantages: It uses at least two laser rangefinders, all of which are located on the same horizontal plane. By sliding the laser rangefinders within the first groove, the distance between adjacent rangefinders can be easily adjusted. In use, one laser rangefinder is aligned with the road traffic marking, while the other is offset. Each rangefinder measures the distance L1 from its own body to the road traffic marking and the distance L2 from its own body to the ground. The actual thickness of the road traffic marking can be obtained by subtracting L1 from L2. This method effectively reduces the workload of surveyors and improves the efficiency of road traffic marking thickness measurement. Furthermore, by using a marker pen to mark the road traffic marking, the surveyor can clearly see the trajectory of the laser rangefinder measuring the road traffic marking thickness.

[0008] Furthermore, each of the fastening components includes: a mounting plate and a locking screw. The mounting plate is fixed to the side wall of the mounting base, the locking screw passes vertically through the mounting plate and is threadedly connected to the mounting plate. The top of the first slide groove is provided with a plurality of locking holes evenly distributed along its axial direction. The locking screw is used to be threadedly connected to the locking holes, and a handle is provided at the end of the locking screw.

[0009] Furthermore, the connecting assembly includes: a mounting cylinder, a spring, and a mounting post. The mounting cylinder is fixed to the bottom of the crossbar, and the bottom of the mounting cylinder is recessed to form a groove. One end of the mounting post is slidably disposed in the groove, and the spring is also disposed in the groove.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-4 As shown in the figure, this utility model embodiment proposes a road traffic marking thickness measurement and marking device, including: a box 1, a slide rail 5, and a laser rangefinder 7. The bottom of the box 1 is provided with wheels 2, and the bottom of the box 1 is also provided with a mounting groove 3. The slide rail 5 is horizontally fixed to the top of the mounting groove 3 by a connecting rod 4. The bottom of the slide rail 5 is provided with a first sliding groove 6. There are at least two laser rangefinders 7. Each laser rangefinder 7 is slidably set in the first sliding groove 6 by a mounting component, and each mounting component has a fastening component on one side for locking the laser rangefinder 7 in the first sliding groove 6. The side wall of the slide rail 5 is provided with a crossbeam 8, and the bottom of the crossbeam 8 is provided with a marking pen 9 by a connecting component.

[0020] The laser rangefinder 7 has at least two units, and all laser rangefinders 7 are located on the same horizontal plane. By sliding the laser rangefinders 7 in the first groove 6, the distance between adjacent laser rangefinders 7 can be easily adjusted. In use, one laser rangefinder 7 is aligned with the road traffic marking, while the other laser rangefinder 7 is offset from the road traffic marking. The laser rangefinder 7 measures the distance L1 from its body to the road traffic marking and the distance L2 from its body to the ground. The actual thickness of the road traffic marking can be obtained by subtracting L2 from L1. This method of measuring the thickness of road traffic markings can effectively reduce the burden on surveying personnel and improve the efficiency of road traffic marking thickness measurement. By setting a marker pen 9, the marker pen 9 marks the road traffic marking, making it easy for surveying personnel to clearly see the trajectory of the laser rangefinder 7 in measuring the thickness of the road traffic marking.

[0021] like Figure 2 as well as Figure 3As shown, each of the mounting components includes: a mounting base 10 and a slider 11. The side wall of the first slide groove 6 is provided with a second slide groove 12. The mounting base 10 is slidably disposed in the first slide groove 6, and the side wall of the mounting base 10 is provided with a slider 11 that is slidably connected to the second slide groove 12. Each of the fastening components includes: a mounting plate 13 and a locking screw 14. The mounting plate 13 is fixed to the side wall of the mounting base 10. The locking screw 14 passes vertically through the mounting plate 13 and is threadedly connected to the mounting plate 13. The top of the first slide groove 6 is provided with a plurality of locking holes 16 evenly distributed along its axial direction. The locking screw 14 is used to be threadedly connected to the locking holes 16. The end of the locking screw 14 is provided with a handle 15.

[0022] When adjusting the distance between adjacent laser rangefinders 7, simply rotate the locking screw 14 to disengage it from the corresponding locking hole 16, and then push the mounting base 10 to slide in the first slide groove 6, thereby adjusting the interval between the laser rangefinders 7. This allows the road traffic marking thickness measurement and marking equipment to be applicable to the measurement of road traffic markings of different widths, improving its practicality and facilitating the disassembly of the laser rangefinders 7.

[0023] like Figure 4 As shown, the connecting assembly includes: a mounting cylinder 17, a spring 20, and a mounting post 19. The mounting cylinder 17 is fixed to the bottom of the crossbar 8, and the bottom of the mounting cylinder 17 is recessed to form a groove 18. One end of the mounting post 19 is slidably disposed within the groove 18. The spring 20 is also disposed within the groove 18, and under the elastic force of the spring 20, one end of the mounting post 19 extends out of the groove 18. The marking pen 9 is fixed to the end of the mounting post 19 that extends out of the groove 18. The side wall of the mounting post 19 is provided with a locking groove 21, and the side wall of the mounting cylinder 17 is provided with a fixing screw 22. The fixing screw 22 is threadedly connected to the mounting cylinder 17 and is used to insert into the locking groove 21. The side wall of the housing 1 is provided with a push rod 26.

[0024] Specifically, the marker pen 9 can be a marker pen or a charcoal pencil. By setting a locking groove 21 on the side wall of the mounting post 19, the mounting post 19 can be pushed into the groove 18. When the fixing screw 22 is aligned with the locking groove 21, the fixing screw 22 can be rotated to insert it into the locking groove 21. Under the restriction of the fixing screw 22, the mounting post 19 and the marker pen 9 can be kept away from the ground, preventing the marker pen 9 from continuously marking on the ground when not measuring.

[0025] As one embodiment, a display screen 24 is also installed on the top of the housing 1 via a mounting bracket 23. A storage slot is provided on the side wall of the housing 1, and an opening and closing door 25 is provided in the storage slot for opening and closing. A built-in power supply and a controller are provided in the storage slot. The built-in power supply is electrically connected to the display screen 24 and the laser rangefinder 7. The laser rangefinder 7 is used to transmit the measured data to the controller, and the controller transmits the recorded data to the display screen 24 for display. When the device is pushed to walk at a constant speed on the ground, the controller can set a certain time interval for the laser rangefinder 7 to perform timed measurements, thereby realizing interval sampling. The laser rangefinder 7 transmits the measured data to the controller, and the controller transmits the data to the display screen 24. The display screen 24 is also provided with a data storage device for easy saving of the measurement data.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
