Problems solved by technology

[0002] At present, there are solutions such as laser beam-to-shoot alarm technology, acoustic emission-based monitoring, sensor monitoring, and circuit monitoring. Most of the solutions have disadvantages such as high cost and difficult implementation. Therefore, a simple, direct, low-cost, and low-cost solution is required. It can not only monitor the breaking and falling of bolts, but also detect the loosening of bolts at the same time, and the bolt tightening monitoring system with alarm

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, a bolt fastening monitoring system using a proximity sensor includes a proximity sensor 1, a sensor bracket 2, an alarm device, a monitoring device, and the like. Proximity sensor 1 is installed on sensor bracket 2, and is aligned with measured bolt 3 and nut 4 on rotating component 5, and proximity sensor bracket 2 is connected on relatively stationary component 6 (such as the body of the hub).

[0019] During the rotation or movement of the parts, at least one proximity sensor 1 detects each bolt 3 and nut 4 in turn. When the bolt 3 is loose, the proximity sensor 1 detects the missing pulse or level signal A, such as figure 2 shown. After identifying the missing signal, the proximity sensor 1 transmits the detected missing pulse or level signal to the alarm device, and the alarm device will give an alarm.

Abstract

The invention relates to a bolt fastening monitoring system by using proximity sensors. The system includes proximity sensors, sensor supports, an alarm device and a monitoring device; at least one proximity sensor installed on a static member on the outside of a rotating body is used for detecting the bolt fastening situations of a rotating device; the proximity sensors are installed on the sensor supports, align to to-be-detected bolts and nuts on a rotating member, and is used for successively detecting each bolt and nut during rotating; and the proximity sensors are connected to the alarmdevice and the monitoring device. The system is simple, direct and low in costs; and the system can monitor the fracture and falling of the bolts and detect the loosening of the bolts to perform alarm.

Description

technical field [0001] The invention relates to a bolt fastening monitoring system, in particular to a device for monitoring bolt fastening during rotation or movement. Background technique [0002] At present, there are solutions such as laser beam-to-shoot alarm technology, acoustic emission-based monitoring, sensor monitoring, and circuit monitoring. Most of the solutions have disadvantages such as high cost and difficult implementation. Therefore, a simple, direct, low-cost, and low-cost solution is required. It is a bolt tightening monitoring system that can not only monitor the breaking and falling of bolts, but also detect the loosening of bolts and alarm. Contents of the invention [0003] The present invention is to provide a bolt fastening monitoring system using a proximity sensor. The system is simple, direct, and low in cost. It can not only monitor the breakage of the bolt, but also detect the loosening of the bolt at the same time and give an alarm. [0004...
