Description
Technical field
The present invention relates to load cell, specifically a kind of bolt to trapped orbit carries out the sensing of forces testing
Device.
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.Whether there is on rail 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.
At present, in terms of the stress of bolt in fastening device for rails is detected immediately, still belong to blank.
Invention content
The purpose of the present invention is to provide a kind of track fixing bolt forces testing sensors, which can
The force-bearing situation of bolt in instant detection fastening device for rails.
To achieve the above object, the present invention uses following scheme：Track fixing bolt forces testing sensor, it has one
In the response body of cuboid, the mounting hole passed through for bolt is provided in the middle part of response body, the opposite both sides of response body connect respectively
Fulcrum bearing is connected to, response body is in aerial shape relative to fulcrum bearing, and having a pair on the other opposite both sides of response body takes the shape of the letter U
Notch, the openend of each notch is equipped with the test beam and transition beam being connected with each other, test one end of beam and transition beam with should
Variant, which is connected, closes the openend of its notch, and transition beam is neighbouring with fulcrum bearing, and test beam is lamellar, tests two bottoms of beam
Face 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, tests beam
Any one bottom surface on be fixed with the foil gauge of one group of measurement shear strain, each foil gauge is connected to conducting wire.
By said program as it can be seen that detected bolt is passed through the mounting hole in the middle part of response body, consolidated by bolt and ground
It is fixed, two fulcrum bearings is made to form 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 can generate 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 the shearing that bolt is subject to is can detect by the foil gauge tested on beam
Power.
Rational in infrastructure, dependable performance of the invention, it accurately can carry out stress inspection to the bolt in fastening device for rails
It surveys, reliable data is provided for traffic safety.
Description of the drawings
The structure chart of Fig. 1 one embodiment of the invention；
The use state diagram of Fig. 2 present invention.
Specific embodiment
With reference to embodiments and attached drawing further illustrates the present invention.
Referring to Fig. 1
Track fixing bolt forces testing sensor provided by the invention has the response body 2 that one is in cuboid, response body 2
Middle part 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, response body 2 relative to
Fulcrum bearing 1 is in aerial shape.Response body 2 has a pair of notch 2b to take the shape of the letter U on other opposite both sides, each notch 2b's
One end of test beam 4 and transition beam 3 of the openend equipped with interconnection, test beam 4 and transition beam 3 is connected with response body to be lacked
The openend closing of mouth 2b.Transition beam 3 and fulcrum bearing 5 are neighbouring, and test beam 4 is lamellar, test two bottom surfaces and the strain of beam 4
The upper surface of body is vertical.The foil gauge 5 of one group of measurement bending strain is fixed in the bottom on notch 2b surfaces（3AA types）, test
The foil gauge 6 of one group of measurement shear strain is fixed on any one bottom surface of beam 4（3HA types）, each foil gauge 5,6, which is connected to, leads
Line.In Fig. 1, each foil gauge connects conducting wire and 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
Nogata to thickness by both ends to intermediate smooth thinning.
Referring to Fig. 1, Fig. 2
It is provided by the invention it is bolt strained test sensor in use, prepare a pedestal 9, fulcrum bearing 1 is made to be landed on pedestal,
Detected bolt 7 is passed through to the mounting hole 2a and pedestal 9 at 2 middle part of response body, is supported in pedestal 9 by ground 10 and rail 8
Under state, by bolt 7 and the bottom plate connecting fixed on the ground, bolt 7 is made to be relatively fixed with ground, pedestal 9 is to rail 8 and ground
Face 10 forms compressing, the conducting wire that foil gauge 6, foil gauge 5 are connect is connected with detecting instrument, you can bolt 7 is examined immediately
It surveys.When vehicle is by rail 8, response body 2 and test beam 4 can generate deformation, pass through one group of foil gauge 5 of the bottom on notch surface
The pulling force that detectable bolt 7 is subject to can detect the shearing force that bolt is subject to by the foil gauge 6 tested on beam.In addition, using
When, the case 11 coordinated with pedestal 9 can be prepared（In Fig. 2 shown in dotted line）, it is by case 11 that the head of response body 8 and bolt 7 is close
Envelope can prevent the erosion of rainwater, ensure service life.
