[0028] The roadbed compaction device of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0032] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] Please see Figure 1-6 This utility model provides a technical solution: a roadbed compaction device for highway engineering, including a road roller 1, side mounting bolts 2, locking nuts 3, track windows 4, movable plates 5, front measuring probes 6, connecting bolts 7, base plate 8, upper reinforcing plate 9, protective plate 10, lower reinforcing plate 11, limiting window 12, vertical threaded rod 13, positioning nut 14, base plate 15 and rear measuring probe 16. The side mounting bolts 2 are fixed on the outer wall of the front end of the road roller 1, and the locking nuts 3 are installed on the side mounting bolts 2. The side mounting bolts 2 pass through the track windows 4. The track windows 4 are opened in the vertical part of the movable plates 5. The inner side of the movable plates 5 is in contact with the outer wall of the front end of the road roller 1. The front measuring probe 6 is installed at the bottom of the horizontal part of the movable plates 5.

[0034] A base plate 8 is installed at the bottom rear end of the road roller 1 via connecting bolts 7. An upper reinforcing plate 9 is fixedly installed on one side of the vertical part at the top of the base plate 8. A protective plate 10 is fixedly installed at the front bottom of the base plate 8. A lower reinforcing plate 11 is fixedly installed at the rear side of the protective plate 10.

[0035] A limiting window 12 is provided at the rear end of the horizontal part of the substrate 8. A vertical threaded rod 13 is installed through the limiting window 12. A positioning nut 14 is installed on the vertical threaded rod 13. A bottom plate 15 is fixed to the bottom end of the vertical threaded rod 13. A rear measuring probe 16 is installed on the bottom surface of the bottom plate 15.

[0036] In this example, the side mounting bolt 2 is slidably connected to the track window 4. The length of the track window 4 is greater than half of the length of the vertical part of the movable plate 5. The above structural design enables the movable plate 5 to stably slide relative to the side mounting bolt 2 with the track window 4 and adjust the working height of the movable plate 5.

[0037] In this example, the center of the movable plate 5 and the center of the side mounting bolt 2 are on the same vertical plane. The side view shape of the movable plate 5 is an "L" shape. The above structural design enables the movable plate 5 to have high installation stability and enables the movable plate 5 to provide a stable installation foundation for the front measuring probe 6.

[0038] In this example, the front view shape of the substrate 8 is a "丄" shape. Connecting bolts 7 are equally spaced on the front end of the horizontal part and the vertical part of the substrate 8. The above structural design enables the substrate 8 to be stably installed at the bottom rear end of the road roller 1.

[0039] In this example, the front view shape of the upper reinforcement plate 9 is a right triangle. The upper reinforcement plates 9 are equally spaced. The above structural design can strengthen the structure of the substrate 8 and ensure that the substrate 8 can work stably for a long time.

[0040] In this example, the lower reinforcement plates 11 are equally spaced behind the protective plate 10. The bottom end of the protective plate 10 is lower than the bottom end of the rear measuring probe 16. The above structural design enables the protective plate 10 to have high structural strength and can protect the rear measuring probe 16 for stability.

[0041] In this example, the top view shape of the limiting window 12 is a "U" shape. The limiting windows 12 are equally spaced. The above structural design enables the vertical threaded rod 13 to be conveniently installed and disassembled through the limiting window 12, and multiple groups of vertical threaded rods 13, bottom plates 15 and rear measuring probes 16 can be installed.

[0042] In this example, the vertical threaded rod 13 is slidably connected to the limiting window 12. Positioning nuts 14 are symmetrically installed on the vertical threaded rod 13 on the upper and lower sides of the limiting window 12. The above structural design enables the vertical threaded rod 13 to stably slide vertically and horizontally along the limiting window 12 and be quickly locked by the positioning nuts 14.

[0043] Working principle: When in use, first rotate the locking nut 3 away from the outer side of the movable plate 5, push the movable plate 5 with the track window 4 to slide vertically along the side mounting bolt 2 until the working height of the front measuring probe 6 at the bottom of the movable plate 5 is appropriate, then rotate the locking nut 3 to press the movable plate 5 into contact with and fix it to the outer wall of the road roller 1.

[0044] Then, the vertical threaded rod 13 is slid into the end opening of the limiting window 12, and the symmetrically distributed positioning nuts 14 are rotated away from the upper and lower end faces of the rear end of the horizontal part of the base plate 8. The vertical threaded rod 13 is pushed to slide and adjust horizontally and vertically along the limiting window 12 until the position of the rear measuring probe 16 is appropriate. The symmetrically distributed positioning nuts 14 are rotated to press and fix the upper and lower end faces of the rear end of the horizontal part of the base plate 8. The road roller 1 is started to operate normally. The front measuring probe 6 and the rear measuring probe 16 perform real-time detection of the roadbed flatness and process and compare the data using existing data processing equipment.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
