Can only be by manually finding not have safe and reliable robotization means and detected for this class problem at present.
Summary of the invention
The purpose of this utility model is, provides a kind of effective means to monitor the whether intact of screwed connection, when getting loose appears in screwed connection, can accurately judge and in time give a warning.
For this reason, a kind of screw thread of the utility model detection supervisory system that gets loose, it comprises: the one or more screw thread sensor that gets loose, described screw thread get loose the sensor screw thread physical message and generate sensing signal; Center processing unit, it is connected with the described one or more screw thread sensor communication that gets loose, and receives the sensing signal that it sends; Display device, it is connected to described center processing unit, is subjected to described center processing unit control display message; And acoustic-optic alarm, it is connected to described center processing unit, is subjected to described center processing unit control carrying out sound and/or luminous warning.
Preferably, described system comprises also and the screw thread corresponding signal transmitting device of number of sensors that gets loose that described signal transmitting device is for being converted into described sensing signal in the device of the receptible signal of center processing unit.
Wherein, the described screw thread sensor that gets loose comprises the range sensor of the spacing between specific 2 on the pin thread spare that detects described screw thread and the mother buckle.For example, at least a in laser sensor, infrared sensor, the sonac.
Wherein, the described screw thread sensor that gets loose also can comprise image capturing device, and is respectively arranged with positioning mark on the pin thread spare of described screw thread and mother buckle.
Perhaps, the wherein said screw thread sensor that gets loose comprises the pin thread spare that detects described screw thread and mother buckle angular transducer in relative rotation.For example, comprise at least a in inertial sensor or the gyroscope.
Perhaps, the described screw thread sensor that gets loose also can comprise the pin thread spare that detects described screw thread or the sensor of the moment of torsion on the mother buckle.For example, comprise at least a in foil gauge or the strain gauge sensor.
The beneficial effects of the utility model are, can obtain in real time to detect and monitored results by this system, get loose and in time to indicate for screw thread, and can send warning message, thereby allow the operating personnel in time overhaul, reduce and alleviate the loss and the infringement that occur getting loose and cause owing to monitored screw thread.
Description of drawings
Fig. 1 is the get loose structural representation of the embodiment that detects supervisory system of the utility model screw thread.
Embodiment
Below will release, dropout, stripped thread and or problem such as disconnected button be referred to as and get loose so that narrate.Screw thread gets loose and has the feature of some general character, for example relative rotation or the displacement of pin thread and box, the external change in torque that is presented as variable in distance between two specified points on pin thread and the box or screw thread surface.
Whether the utility model detects screw thread and gets loose by detecting above-mentioned various variation just, and comes the situation of a plurality of screw threads is carried out integral monitoring by constructing corresponding supervisory system.Screw thread of the present utility model get loose the embodiment that detects supervisory system structural representation as shown in Figure 1.
Be that example describes so that n screwed connection (screwed connection 1, screwed connection 2...... screwed connection n) monitored among the figure, obviously also can only monitor 1 or 2 screwed connection.Wherein, corresponding each screwed connection is provided with the screw thread sensor (screw thread get loose sensor 1, screw thread get loose the sensor 2...... screw thread sensor n that gets loose) that gets loose, and a plurality of screw threads sensor that gets loose can be that same type also can be dissimilar.With screw thread get loose sensor output by the signal transmitting device that is attached thereto convert to be suitable for signal form that center processing unit receives after, by center processing unit sensing data is handled, further judge whether to get loose.And show by the display device that is connected with center processing unit state, and when judging that having screw thread to get loose takes place, show by acousto-optic warning unit to screwed connection.
Wherein, because the signal output form difference of various sensors of various types, the signal transmitting device may be that analog to digital converter, voltage changer, current-voltage signal converter etc. are multi-form, and those skilled in the art should select according to the concrete condition of sensor.The signal transmitting device is also nonessential, and when the signal of sensor output can directly be discerned by center processing unit, the signal transmitting device was omissible.
Center processing unit can select for use any element with input/output end port and signal and/or data-handling capacity such as single-chip microcomputer, Programmable Logic Controller (PLC) or any programmable logic device (PLD) (CPLD) to realize according to different monitoring needs and cost budgetings.Display device can be used commercially available liquid crystal display, LED display, charactron or even a row LED bulb etc.And audible-visual annunciator can use the element of prior aries such as hummer, bulb.
When monitored screwed connection One's name is legion, when to such an extent as to the input port of center processing unit is not enough to satisfy the demands, can be between signal transmitting device and center processing unit the signalization delivery unit, with timesharing or the sampling of branch location of carrying out signal, for example signal transmission unit can use two-way code translator to realize.
According to the difference of the parameter that detects, can select for use different sensors to come as the screw thread sensor that gets loose.Can compare by the standard value when center processing unit is fastening with the output data of sensor and screw thread and judge that whether it gets loose.
For example, the described screw thread sensor that gets loose can comprise the range sensor of the spacing between specific 2 on the pin thread spare that detects described screw thread and the mother buckle.For example, the sensor that is used for finding range such as laser sensor, infrared sensor, sonac is at least a.
Perhaps, the described screw thread sensor that gets loose also can comprise image capturing device, and is respectively arranged with positioning mark on the pin thread spare of described screw thread and mother buckle.After collecting image information, judge two distances between the positioning mark through image recognition algorithm.Such data transmission and calculated amount are all bigger, are suitable for the occasion of special requirement.
Again or, the wherein said screw thread sensor that gets loose comprises the pin thread spare that detects described screw thread and mother buckle angular transducer in relative rotation.For example, comprise at least a in inertial sensor or the gyroscope.The variation of the acceleration difference by detecting pin thread and box detects the rotation of screw thread.
Or the described screw thread sensor that gets loose also can comprise the pin thread spare that detects described screw thread or the sensor of the moment of torsion on the mother buckle.For example, comprise at least a in foil gauge or the strain gauge sensor.This is mainly used under the fixing applicable cases in screw thread two ends the detection to particular point.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
