Description
Technical field
The utility model is related to load cell, specifically a kind of bolt to trapped orbit carries out forces testing
Sensor.
Background technology
Fixation of the rail of train or subway on roadbed is completed by fastening device for rails, existing most steel
Rail fixing device usually has bolt, and after these fastening device for rails fix rail, contained bolt is main stress
One of component.On rail whether there is or not vehicle by when, the force-bearing situation of bolt differs widely in fastening device for rails, rail
On have vehicle by when, can instant detection and analysis bolt force-bearing situation, have positive meaning to the safety of driving.
Currently, in terms of the stress of bolt in fastening device for rails is detected immediately, still belong to blank.
Utility model content
The purpose of this utility model is to provide a kind of track fixing bolt forces testing sensor, forces testing sensings
Device can be instant detection fastening device for rails in bolt force-bearing situation.
To achieve the above object, the utility model uses following scheme：Track fixing bolt forces testing sensor, it has
It is in the response body of cuboid to have one, and the mounting hole passed through for bolt, the opposite both sides of response body point are provided in the middle part of response body
It is not connected with fulcrum bearing, response body is in aerial shape relative to fulcrum bearing, and response body has a pair on other opposite both sides
The notch to take the shape of the letter U, the open end of each notch are equipped with the test beam and transition beam that are connected with each other, test one end of beam and transition beam
It is connected with response body and closes the open end of its notch, transition beam is neighbouring with fulcrum bearing, and test beam is lamellar, tests the two of beam
A bottom surface is vertical with the upper surface of response body, and the foil gauge of one group of measurement bending strain is fixed in the bottom on notch surface, surveys
The foil gauge that one group of measurement shear strain is fixed on any one bottom surface of beam is tried, each foil gauge is connected to conducting wire.
It is solid by bolt and ground by said program as it can be seen that detected bolt is passed through the mounting hole in the middle part of response body
It is fixed, so that two fulcrum bearings is formed compressing to rail and ground respectively, the conducting wire that each foil gauge is connected to is connected with detecting instrument, you can
Bolt is detected immediately, when vehicle passes through rail, response body and test beam will produce deformation, pass through the bottom on notch surface
One group of foil gauge in portion can detect the pulling force that bolt is subject to, and can detect the shearing that bolt is subject to by the foil gauge tested on beam
Power.
The utility model is reasonable for structure, dependable performance, it can accurately to the bolt in fastening device for rails carry out by
Power detects, and reliable data are provided for traffic safety.
Description of the drawings
The structure chart of one embodiment of Fig. 1 the utility model；
The use state diagram of Fig. 2 the utility model.
Specific implementation mode
With reference to embodiments and attached drawing further illustrates the utility model.
Referring to Fig. 1
It is in the response body 2 of cuboid that track fixing bolt forces testing sensor provided by the utility model, which has one,
The middle part of response body 2 is provided with the mounting hole 2a passed through for bolt, and the opposite both sides of response body 2 are connected separately with fulcrum bearing 1, strain
Body 2 is in aerial shape relative to fulcrum bearing 1.Response body 2 has a pair of notch 2b to take the shape of the letter U on other opposite both sides, often
The open end of one notch 2b is equipped with the test beam 4 being connected with each other and transition beam 3, tests one end and the response body of beam 4 and transition beam 3
It is connected and closes the open end of its notch 2b.Transition beam 3 and fulcrum bearing 5 are neighbouring, and test beam 4 is lamellar, testing beam 4 two
Bottom surface is vertical with the upper surface of response body.It is fixed with the foil gauge 5 of one group of measurement bending strain in the bottom on the surfaces notch 2b
（3AA types）, test the foil gauge 6 that one group of measurement shear strain is fixed on any one bottom surface of beam 4（3HA types）, each to strain
Piece 5,6 is connected to conducting wire.In Fig. 1, each connect conducting wire of foil gauge does not illustrate, omits.
For enable test 4 stress of beam when more sensitive deformation, improve measuring accuracy, in the present embodiment, transition beam 3 is perpendicular
Histogram to thickness by both ends to intermediate smooth thinning.
Referring to Fig. 1, Fig. 2
Bolt strained test sensor provided by the utility model makes fulcrum bearing 1 take a seat in use, one pedestal 9 of preparation
On pedestal, detected bolt 7 is passed through to the mounting hole 2a and pedestal 9 at 2 middle part of response body, in pedestal 9 by ground 10 and iron
In the state that rail 8 supports, by bolt 7 and the bottom plate connecting fixed on the ground, bolt 7 is set to be relatively fixed with ground, pedestal 9 is right
Rail 8 and ground 10 form compressing, and the conducting wire that foil gauge 6, foil gauge 5 are connect is connected with detecting instrument, you can to bolt 7 into
Row detection immediately.When vehicle is by rail 8, response body 2 and test beam 4 will produce deformation, pass through the one of the bottom on notch surface
Group foil gauge 5 can detect the pulling force that bolt 7 is subject to, and can detect the shearing force that bolt is subject to by testing the foil gauge 6 on beam.Separately
Outside, when in use, the case 11 coordinated with pedestal 9 can be prepared（In Fig. 2 shown in dotted line）, by case 11 by response body 8 and bolt 7
Head seal, can prevent the erosion of rainwater, ensure service life.
