10-14.7kN, but staff can only reach the requirement of the former Ministry of Railways by operation empirical evaluation at present, and meanwhile it is anti-slip at present
Validity the inspection of people can only be relied on to confirm, and during inspection, it is also difficult to confirm whether the pulling force up to standard, backstage
It can not know the real-time condition at scene.
In consideration of it, my company develops a kind of pull force calculation intelligence fastener, the fastener is embedded using pulling force sensor
Design, combines together with fastener, the pulling force that fastener is born directly is detected, while wearing dual-colored LED lamp, when threshold values reaches
The anti-slip value of setting, fastener display green light, otherwise shows red light, meanwhile, fastener is by wireless module, what is acquired in real time
Information is sent to backstage, and remote monitoring fastener anti-slip information in real time, if in upper track device, the pulling force of fastener acquisition is less than
Threshold values, system automatic alarm.
Utility model content
The purpose of this utility model is to provide a kind of pull force calculation intelligence fasteners, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides the following technical solutions：
A kind of pull force calculation intelligence fastener, including sensor metal shell, the sensor metal-back upper and lower ends point
Not She You drag hook and screw rod, be rotation connection between drag hook and sensor metal shell, the sensor metal enclosure interior sets
There is mounting groove, the foil gauge there are four array distribution is set in mounting groove, constitutes pulling force sensor, pulling force sensor electrical connection part
The input terminal of device is managed, sensor metal shell front is equipped with battery case, and battery case is equipped with the buzzing being electrically connected with processor
Device, the sensor metal shell another surface opposite with battery case are equipped with circuit board box, and circuit board box is equipped with and processing
The two-way indicator light that device is electrically connected, the output end of the processor are additionally provided with wireless transmitter, vibration detector, battery detecting
Device, radio-frequency module and RFID tag.
As further program of the utility model：On link block between the drag hook and screw rod and sensor metal-back
Equipped with steel ball rounding slot.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple and reasonable for structure, can be directly
Whether the size for detecting pulling force, have bi-colour light knowledge pulling force up to standard, has the function of that wireless information transfer, backstage can monitor in real time anti-
Validity is slipped, the requirement of live inspection can be removed from, has hardware RFID uniquely good, it can be highly practical with global tracking.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of sensor metal shell in the utility model.
Fig. 3 is the principles of the present invention block diagram.
Wherein：Sensor metal shell 1, drag hook 2, screw rod 3, steel ball rounding slot 4, battery case 5, buzzer 6, mounting groove
7, pulling force sensor 8.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the utility model embodiment, a kind of pull force calculation intelligence fastener, including sensor metal
Shell 1,1 upper and lower ends of sensor metal shell are respectively equipped with drag hook 2 and screw rod 3, drag hook 2 and sensor metal shell 1
Between for rotation connection, and then be convenient for people to use, set on the link block between drag hook 2 and screw rod 3 and sensor metal shell 1
There are steel ball rounding slot 4, the sensor metal shell 1 to be internally provided with mounting groove 7, is set in mounting groove 7 there are four array distribution
Foil gauge constitutes pulling force sensor 8, the input terminal of 8 electrically connected processing device of pulling force sensor, 1 front of sensor metal shell
Equipped with battery case 5, the effect of battery case 5 is powered for all parts in device, and battery case 5 is equipped with and processor electricity
Property connection buzzer, Field Force operate fastener when, after pulling force reaches setting value, instruction buzzer work.When
When threshold values is without effective pull anti-slip threshold values is reached, fastener buzzer voiceless sound；When value of thrust reaches anti-slip pulling force threshold values
When, fastener honey device sends out the sound of " bi, bi, bi...... ", facilitates staff scene to confirm anti-slip state, with battery
The opposite 1 another surface of sensor metal shell of box 5 is equipped with circuit board box, and circuit board box is equipped with electrically to be connected with processor
