Example Embodiment
[0030] Specific implementation mode 1: Combination figure 1 To illustrate this embodiment, a test device for measuring the adhesion of bolts and ice in this embodiment includes a screw 1, a nut 2, a top cover 3, an upper cylinder 4, a partition 5, a lower cylinder 6 and a connecting pin 7. The barrel 4 and the lower barrel 6 are connected by a partition 5, and the upper barrel 4, the lower barrel 6 and the partition 5 are all sealed and fixedly connected. The top cover 3 is installed on the upper barrel 4, and the screw 1 is vertically inserted through The top cover 3 is on and extends in the upper cylinder 4, the screw 1 is screwed on the upper and lower ends of the top cover 3 through the nut 2, and the connecting pin 7 is horizontally penetrated on the lower cylinder 6.
[0031] Since water will expand and contract during freezing, the upper cylinder 4 is made of Q235 steel.
[0032] In the present invention, the screw to be tested passes through the threaded through hole 3-1 of...
Example Embodiment
[0034] Specific implementation manner two: combination figure 1 To describe this embodiment, a threaded through hole 3-1 is opened in the center of the top cover 3 of this embodiment. With this design, the screw 1 can pass through the top cover 3, and the measured length of the screw in the water can be adjusted by the nut 2. The other components and connection relationships are the same as in the first embodiment.
Example Embodiment
[0035] Specific implementation mode three: combination figure 1 To illustrate the present embodiment, an arc-shaped groove 1-2 is provided on the lower end surface of the top cover 3 of the present embodiment. Such a design can be aligned with the center of the upper cylinder, ensuring that the screw is in the middle of the ice during the freezing process, and the test result is more accurate and reliable; other compositions and connection relationships are the same as those in the first or second embodiment.
