Description

Technical Field

[0001] The utility model belongs to the technical field of compaction degree detectors, and more specifically, particularly relates to a real-time road compaction degree detector. Background Art

[0002] The compaction quality of the roadbed and pavement is one of the most important internal indicators of the quality management of road construction. Only by fully compacting the roadbed and pavement structure layers can the strength, stiffness, stability and flatness of the roadbed and pavement be guaranteed, thereby extending the service life of the roadbed and pavement; Among them, Chinese Patent No.: CN202120880327.8 discloses a real-time road compaction detector that can detect the compaction of the roadbed in real time, avoid damage to the roadbed, and improve the detection accuracy. The real-time road compaction detector includes a filter circuit, a 24-bit high-precision data converter, a central processing unit, a display, and a rotating U-shaped frame installed on a roller bracket; the lower end of the opening of the rotating U-shaped frame is hinged at the middle position of both sides of the roller bracket; the lower ends of the opening of the rotating U-shaped frame are respectively provided with a third dynamic displacement sensor and a fourth dynamic displacement sensor; the front end of the roller bracket is provided with a first mounting plate, and the rear end is provided with a second mounting plate; the first mounting plate is provided with a first dynamic displacement sensor below, and the second mounting plate is provided with a second dynamic displacement sensor below; the middle position of the rotating U-shaped frame is provided with a three-axis integrated acceleration sensor. The use of this road compaction real-time detector can effectively improve construction efficiency.

[0003] Based on the above, the inventors have discovered the following problems: the above patent has a relatively good effect on real-time detection of road compaction. During the use of the detector, it is necessary to adjust the rotating U-shaped frame to drive the three-axis integrated acceleration sensor to work in a vertical state with the pressure roller. However, during the adjustment process, the staff needs to align the rotating U-shaped frame and install it with bolts, and cannot quickly determine whether it is in a vertical state. In addition, the operating steps are relatively cumbersome, which indirectly brings inconvenience to the staff.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a real-time road compaction detector is provided to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of the real-time road compaction detector of the utility model are achieved by the following specific technical means:

[0006] A road compaction real-time detector comprises a bracket, a pressure roller is connected and installed inside the bracket, a group of rotating shafts are arranged on the outer walls on both sides of the bracket, a rotating U-shaped frame is rotatably installed on the rotating shaft, a three-axis integrated acceleration sensor is installed on the top of the rotating U-shaped frame, a limiting mechanism is installed inside the rotating U-shaped frame, and a ruler is connected and installed on the surface of one side of the rotating U-shaped frame.

[0007] Furthermore, a limiting plate is fixedly mounted on one end surface of the bracket.

[0008] Furthermore, the limiting mechanism includes a limiting rod, a spring is sleeved on the surface of the limiting rod, a limiting block 1 is fixedly mounted on the surface of the limiting rod, and the limiting block 1 is located on one side of the spring.

[0009] Furthermore, a limiting hole is provided on an outer wall of one side of the bracket, and one end of the limiting rod is installed in the limiting hole.

[0010] Furthermore, one end of the limiting rod passes through the rotating U-shaped frame to the outside where a handle is fixedly installed.

[0011] Furthermore, a second limiting block is fixedly installed on one side surface of the bracket.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the design of the ruler, when the staff installs the rotating U-shaped frame, they can quickly determine whether it is in a vertical state through the ruler. At the same time, during use, they can also quickly observe the degree of shaking during operation. It is very simple and indirectly improves the use efficiency of the detector.

[0014] Through the cooperation among the limit rod, spring and limit block, when the staff needs to use the detector, they can directly rotate the rotating U-shaped frame to a vertical state, and the limit rod will automatically snap into the limit hole, without the need for the staff to use external tools to fix it. The operation steps are very simple. When use is completed, the handle can be directly pulled to drive the limit rod to move and the rotating U-shaped frame can be lowered, which indirectly brings convenience to the staff, and this design greatly increases the practicality.
