Description

Technical Field

[0001] The utility model relates to the technical field of bolt loosening sensor installation, in particular to an installation structure for a hexagonal head installation bolt loosening sensor. Background Art

[0002] Bolts are essential components and play a vital role in industries such as industrial machinery, transportation, mining, energy, and power equipment. However, loosening of bolts or nuts due to mechanical vibration, metal stress, and external loads has always been a headache. Once a bolt becomes loose, it often breaks.

[0003] Therefore, bolt loosening sensors have gradually emerged on the market. Usually, the bolt loosening sensor is installed on the nut using a mounting structure, and an anchor point with a built-in magnet is installed at the end of the threaded head of the bolt. The two are used together to monitor the looseness of the bolt, including detecting the elongation or rotation angle of the bolt to obtain the looseness of the bolt. The installation distance between the bolt loosening sensor and the anchor point needs to be less than 6mm to ensure the accuracy of the detection data.

[0004] Most of the existing bolt loosening sensor mounting structures are compatible with nuts. The bolt loosening sensor is installed on the nut through the mounting structure. However, the bolts used in some specific scenarios are not fastened to the mounting parts by the cooperation of the bolts and nuts. For example, the mounting parts are fastened by a single bolt in conjunction with a threaded hole. The bolts used in the above scenarios lack nuts and only have the hexagonal head exposed. The existing mounting structure cannot adapt to the hexagonal head of the bolt, so the bolt loosening sensor cannot be installed, and the loosening of the bolts used in such cases cannot be monitored.

[0005] To address this situation, the utility model adopts a new installation structure. The bolt loosening sensor is installed on the mounting surface of the mounting part and remains stationary. The anchor point with a built-in magnet is fixed on the hexagonal head of the bolt. When the bolt loosens, the anchor point rotates relative to the bolt loosening sensor, and the magnetic field changes. The sensor detects the loosening of the bolt by monitoring the change in the magnetic field. Utility Model Content
