[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figs. 1-3 This embodiment discloses a roadbed strength testing fixture, including a support 101 and a placement platform 102. The support 101 is provided with a mounting groove 103, and the placement platform 102 is movably connected to the mounting groove 103.

[0034] The mounting groove 103 is a semi-circular groove, and the placement platform 102 is semi-circular. The bottom end of the mounting groove 103 is provided with a first slot 104, and the mounting groove 103 communicates with the outside through the first slot 104. The placement platform 102 is provided with a first placement groove 113, and the bottom end of the first placement groove 113 is provided with a second slot 105, and the first placement groove 113 communicates with the outside through the second slot 105.

[0035] A counterweight ring 106 is installed at the bottom of the placement platform 102.

[0036] In this embodiment, the bottom end of the placement platform 102 extends through the first slot 104 to the bottom of the bracket 101. The placement slot is used to place an ultrasonic detector or other equipment for sampling and testing the strength of the roadbed. The ultrasonic detector is a conventional damage testing instrument with a probe installed in the prior art, and its structure and function will not be described in detail here. After the ultrasonic detector is placed in the placement slot, the probe extends through the second slot 105 to the outside of the placement platform 102. When unevenness or settlement / collapse occurs on the roadbed surface, causing the support 101 installed on the roadbed to tilt, the placement platform 102 can rotate within the mounting groove 103 under its own weight. This ensures that regardless of the tilt angle of the support 101, the placement platform 102 and the ultrasonic detector placed in the first placement groove 113 remain vertically aligned. This guarantees that the ultrasonic waves emitted by the ultrasonic detector can be perpendicularly incident on the roadbed being inspected. Perpendicular incident ultrasonic waves maximize the reflection and reception efficiency, thereby obtaining the clearest and most accurate images or data, ensuring the assessment of the roadbed's strength and internal structure. The accuracy of detection data such as cracks and defects; if the sampling and detection equipment in the first placement slot 113 is a conventional sampling and detection device in the prior art, by ensuring that the sampling and detection device is set vertically, it can also avoid the inaccurate sampling position caused by the tilt of the bracket 101, which would lead to an increase in error in the sampling process and thus affect the accuracy and reliability of the entire detection process; in this embodiment, the counterweight ring 106 is coaxially connected to the placement, and by setting the counterweight ring 106, the weight of the placement platform 102 can be increased, which further improves the efficiency and effect of the placement platform 102 moving to the vertical position when the bracket 101 is tilted.

[0037] In some embodiments, the inner wall of the mounting groove 103 is provided with a plurality of ball cavities, and ball bearings 107 are rolledly connected in the ball cavities. By providing the ball bearings 107, when the bracket 101 is tilted, the sliding friction generated between the placement platform 102 and the mounting groove 103 is transformed into rolling friction. This reduces wear between the placement platform 102 and the mounting groove 103, while improving the efficiency and effectiveness of the placement platform 102 moving to a vertical position.

[0038] In some embodiments, the first placement groove 113 is a stepped groove. The stepped groove allows for the positioning of ultrasonic detectors of different sizes or other detection and sampling devices used for roadbed strength monitoring.

[0039] In some embodiments, the placement platform 102 is provided with a second placement groove 108 that communicates with the first placement groove 113, and the second placement groove 108 communicates with the outside through the second slot 105. In this embodiment, the second placement groove 108 is a circular groove, and the second slot 105 can limit the movement of ultrasonic detectors of different shapes or other detection and sampling devices used for roadbed strength monitoring.

[0040] In some embodiments, a protective cover 109 is installed on the placement platform 102, and the protective cover 109 is detachably connected to the placement platform 102. In this embodiment, a fixing bolt is installed on the protective cover 109, and the protective cover 109 is connected to the placement platform 102 through the fixing bolt. By setting the protective cover 109, the ultrasonic detector or other detection and sampling device used for roadbed strength monitoring located in the first placement slot 113 or the second placement slot 108 can be protected, preventing rainwater or other impurities and dust from adhering to and accumulating on the ultrasonic detector or other detection and sampling device used for roadbed strength monitoring, thus affecting its normal use.

[0041] In some embodiments, the bottom end of the placement platform 102 is provided with a heat dissipation hole communicating with the second slot 105. The heat generated during use by the ultrasonic detector or other detection and sampling device for roadbed strength monitoring located in the first placement slot 113 or the second placement slot 108 can be discharged through the heat dissipation hole, preventing overheating of the ultrasonic detector or detection and sampling device. By placing the heat dissipation hole at the bottom end of the placement platform 102, rainwater can be prevented from entering the first placement slot 113 and the second placement slot 108 through the heat dissipation hole during rainfall, thus preventing damage to the equipment in the first or second limiting slot. In some embodiments, one end of the protective cover 109 is hinged to the placement platform 102, and the movable end of the protective cover 109 is detachably connected to the placement platform 102. The movable end of the protective cover 109 is equipped with a fixing bolt, and the movable end of the protective cover 109 is detachably connected to the placement platform 102 through the fixing bolt; by hinged one end of the protective cover 109 to the placement platform 102, the disassembly and assembly efficiency of the protective cover 109 can be further improved, which facilitates the disassembly, assembly and operation of the ultrasonic detector or detection sampling device placed in the first placement slot 113 or the second placement slot 108.

[0042] In some embodiments, a fixing mechanism 110 is installed on the placement platform 102, and the movable end of the protective cover 109 is detachably connected to the placement platform 102 via the fixing mechanism 110. In this embodiment, the fixing mechanism 110 is used to fix the movable end of the placement platform 102.

[0043] In some embodiments, the fixing mechanism 110 includes a threaded rod 111 and a pressure block 112. A stepped platform 114 is fixedly connected to the movable end of the protective cover 109. The pressure block 112 is fixedly connected to the threaded rod 111. The pressure block 112 is threadedly connected to the placement platform 102 through the threaded rod 111. The pressure block 112 is used to limit the movable end of the protective cover 109 after cooperating with the stepped platform 114. When it is necessary to limit the step platform 114, rotate the pressure block 112 above the step platform 114. During the rotation, the pressure block 112 moves downward a certain distance along with the threaded rod 111, so that the pressure block 112 can press the step platform 114 onto the placement platform 102, thereby fixing the protective cover 109. Fixing the movable end of the protective cover 109 by rotating the pressure block 112 can further improve the installation efficiency of the protective cover 109. When it is necessary to disassemble and operate the ultrasonic detector or detection sampling device placed in the first placement slot 113 or the second placement slot 108, rotate the pressure block 112 so that the pressure block 112 is no longer in contact with the step platform 114, and then the protective cover 109 can be opened.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
