[0035] Working principle:
[0036] The accurate measurement of the large-diameter pile hole opening 1 is realized through the cooperation of the aluminum alloy folding ruler frame structure 2, the aluminum alloy passing ruler frame structure 3 and the shaft hinge structure 4. The aluminum alloy folding ruler frame structure 2 comprises a first folding ruler 20 and a second folding ruler 21, which are connected with the shaft hinge structure 4 through a connecting disc 26, so that the folding ruler frame can be adjusted according to the diameter of the pile hole opening, and the passing hole 23 on the tie steel sheet 22 is located at the half position, which helps to keep balance and stability when adjusting the caliper, while providing necessary flexibility. The aluminum alloy passing ruler frame structure 3 comprises a first passing ruler 30 and a second passing ruler 31, which are adapted to different sizes of pile hole openings through a telescopic reset cursor piece, the positioning cursor 34 on the cursor sliding rail 32 can slide along the sliding rail to realize accurate measurement, the cooperation of the pin 33 and the cursor slot 35, and the fixation of the positioning bolt 37 ensure the accurate positioning of the cursor ruler, and the combination of the spring positioning sleeve 38, the compression spring 39 and the tight bead pull rope 310 provides the cursor ruler with the function of automatic reset, so that the measurement process is more convenient. The shaft hinge structure 4 is the core of the whole caliper, which comprises a bearing 40, a bearing inner shell 41, a shaft joint ring 42, a disc groove 43, a bearing outer shell 44, a main shaft pin 45 and a sealing shaft cover 46, which work together to ensure the stable rotation and accurate positioning of the folding ruler frame and the passing ruler frame. The combination of the bearing 40 and the shaft joint ring 42 reduces wear and improves measurement accuracy. The main shaft pin 45 provides a stable rotating shaft, and the sealing shaft cover 46 protects the internal structure from dust and moisture. During the measurement process, the user first unfolds the folding ruler frame 2 and places it on the top of the pile hole opening 1, adjusts the tie steel sheet 22 and the clamping interface 24 to ensure that the folding ruler frame is firmly fixed on the pile hole opening, then accurately measures through the positioning cursor 34 on the cursor sliding rail 32, and the sliding of the cursor ruler and the action of the compression spring 39 make the measurement more flexible and accurate. Finally, the position of the folding ruler frame and the passing ruler frame can be adjusted through the rotation of the shaft hinge structure 4 to adapt to pile hole openings of different diameters. This design makes the caliper flexible to adapt to pile hole openings of different diameters, while providing high-precision measurement results, and is suitable for re-measuring work of large-diameter pile hole openings with circular cross sections.
