[0020] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] Embodiment 1, a municipal road pavement thickness detection device, the municipal road pavement thickness detection device includes: a mounting base plate 1, a thickness detection device body 2.

[0023] Specifically, a plurality of symmetrically arranged self-locking universal wheels 11 are provided on the lower side of the mounting base 1. The self-locking universal wheels 11 can make the overall movement of the device more convenient. A thickness detection device body 2 is provided on the upper side of the mounting base 1. The thickness detection device body 2 is a prior art. The thickness detection device body 2 includes a drill rod 3 driven by a motor. A notch 12 for sliding the drill rod 3 is provided on one side of the mounting base 1. The notch 12 can facilitate the work of the drill rod 3. One end of the mounting base 1 is slidably connected to a mounting plate 4. A spring 5 is fixedly connected between the mounting plate 4 and the mounting base 1 and the mounting plate 4 One end of the tool is connected with a grinding block 6 which is fixed to the mounting plate 4 by a fixing bolt 7. The grinding block 6 is arranged in a "T" shape and the end of the grinding block 6 close to the drill bit of the drill rod 3 is arranged into an inclined surface. One side of the mounting base plate 1 is provided with a positioning component for limiting the sliding of the mounting plate 4. When the drill bit of the drill rod 3 is severely worn, the positioning component is controlled to release the restraint on the mounting plate 4, and the mounting plate 4 will drive the grinding block 6 to slide together under the action of the No. 1 spring 5. After sliding, the inclined surface of the grinding block 6 will contact the drill bit of the drill rod 3. At this time, the motor is started to control the rotation of the drill rod 3, and the drill bit of the drill rod 3 can be ground.

[0024] In order to facilitate the installation of the grinding block 6 and the fixing bolt 7, a positioning hole 61 for the sliding insertion of the fixing bolt 7 is opened on one side of the grinding block 6 of the present application, and a slot 43 for the sliding insertion of the grinding block 6 is opened on one side of the mounting plate 4. One side of the slot 43 is connected to a bolt hole 44 for the threaded insertion of the fixing bolt 7. The slot 43 can facilitate the installation of the grinding block 6, and the cooperation of the positioning hole 61 and the bolt hole 44 can allow the fixing bolt 7 to better fix the grinding block 6.

[0025] In order to ensure the stability of the mounting plate 4, a slide bar 41 arranged in a "T" shape is fixedly connected to one side of the mounting plate 4 of the present application, and a slide groove 13 for sliding the slide bar 41 is provided on one side of the mounting base plate 1. Through the cooperation between the slide bar 41 and the slide groove 13, the mounting plate 4 can be stably slidably installed on the mounting base plate 1.

[0026] In order to better install the No. 1 spring 5, one side of the mounting base 1 of the present application is fixedly connected to a No. 1 protruding plate 14, and one end of the mounting plate 4 is fixedly connected to a guide rod 42. The guide rod 42 and the No. 1 protruding plate 14 are slidably plugged and the No. 1 spring 5 is located between the No. 1 protruding plate 14 and the mounting plate 4. The guide rod 42 can further constrain the sliding trajectory of the mounting plate 4, so that the grinding block 6 can be more accurately docked with the drill rod 3, and the No. 1 protruding plate 14 can provide the No. 1 spring 5 with a mounting surface, allowing the No. 1 spring 5 to better push the mounting plate 4 to slide.

[0027] In order to better limit the sliding of the mounting plate 4, the positioning assembly of the present application includes a limit rod 8, which is located on one side of the mounting base plate 1 and is slidably connected to the mounting base plate 1. A No. 2 spring 9 is fixedly connected between the limit rod 8 and the mounting base plate 1. A limit hole 45 for the limit rod 8 to slide and insert is opened on one side of the mounting plate 4. When the grinding block 6 is not in use, the sliding mounting plate 4 is moved away from the drill rod 3, and then the limit rod 8 is slidably inserted into the limit hole 45 under the action of the No. 2 spring 9, thereby limiting the sliding of the mounting plate 4 and preventing the mounting plate 4 from interfering with the operation of the drill rod 3.

[0028] In order to better install the limit rod 8, one side of the limit rod 8 of the present application is fixedly connected with a baffle 81, and one side of the mounting base 1 is fixedly connected with a No. 2 protrusion 15. The limit rod 8 and the No. 2 protrusion 15 are slidably plugged in, and the No. 2 spring 9 is located between the baffle 81 and the No. 2 protrusion 15. One end of the limit rod 8 is fixedly connected with a shift rod 82. The No. 2 protrusion 15 can provide a mounting surface for the limit rod 8 and the No. 2 spring 9. The baffle 81 can allow the No. 2 spring 9 to be better installed, and the shift rod 82 can better control the sliding of the limit rod 8.

[0029] During actual implementation, when it is determined that the drill rod 3 is severely worn, ensure that the drill rod 3 is in the initial position, and then control the limit rod 8 to slide away from the mounting plate 4 by toggling the toggle lever 82. At this time, the mounting plate 4 will push the mounting plate 4 and the grinding block 6 to slide toward the drill rod 3 under the action of the No. 1 spring 5. Finally, the inclined surface of the grinding block 6 will contact the drill bit of the drill rod 3. At this time, the motor is allowed to control the rotation of the drill rod 3, so that the drill rod 3 can be ground during the rotation process, thereby increasing the service life of the drill rod 3 and reducing the cost of use.

[0030] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
