As shown in attached drawing 1 to attached drawing 9, the specific implementation of the utility model gapless track micro-displacement measuring device is given
Example, the utility model is described in further detail in the following with reference to the drawings and specific embodiments.
The judgement of the utility model gapless track micro-displacement measuring device is steel in the method that rail 2 is in zero stress state
Rail 2 is in non-displacement state at ambient temperature, i.e., rail 2 has been bumped against rebound using rail-impacting block 3, be treated as rail 2 and be in
Zero stress state.Therefore, accurate, rapid survey rail 2 bouncing displacement becomes extremely important.When rail 2 is in rebound state
When, it is displaced very little, is not easy to observe the micro-displacement that rail 2 rebounds using traditional displacement observation method.And the utility model has
The gapless track micro-displacement measuring device of body embodiment description carries out the measurement of rail micro-displacement using amesdial 30, can be to steel
Micro-displacement when rail 2 rebounds carries out more accurate quantization measurement, guarantees that the zero stress state of rail 2 is more uniform, sufficiently
Realize the even, quasi-, enough of 2 destressing of rail.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of embodiment of the utility model gapless track micro-displacement measuring device, specifically
Include:
The fixation device 10 being installed on sleeper 5；
The mobile device 20 being installed on rail 2 can be moved with the movement of rail 2, and mobile device 20 includes towards steel
The baffle 22 of 2 length direction of rail setting；
And it is set to the amesdial 30 on fixed device 10, the measuring staff 31 and 22 planar vertical contact of baffle of amesdial 30；
When carrying out stress state measurement using micro-displacement measuring device 1, fixed device 10 is together with mobile device 20
It is used cooperatively.When carrying out destressing to rail 2 using rail-impacting block 3, rail 2 is hit by rail-impacting block 3, Zhi Daoqian
Table 30 is divided to measure the bouncing displacement opposite with crash direction, then it is assumed that rail 2 is in zero stress state.If amesdial 30
It is unmeasured to bouncing displacement relative to initial makeup location, then it is assumed that rail 2 is not up to zero stress state.
Mobile device 20 further comprises the support 21 for the inverted u-shaped being mounted on rail 2, and support 21 is along 2 width of rail
The two sides in direction are provided with mounting hole, pass through mounting hole by bolt 2 23 and mobile device 20 is fixed on rail 2, baffle 22
It is fixed on the top of support 21.Bolt 2 23 is unclamped, mobile device 20 can be moved along the length direction of rail 2.It will using glue
Baffle 22 is fixed on support 21, and the plane of baffle 22 is vertical with longitudinal direction (i.e. the length direction of rail 2) of support 21.It uses
When the support 21 of inverted u-shaped is set on rail 2, screw four bolts 2 23 on support 21, that is, can guarantee mobile device
20 can be moved with rail 2.
The measuring instrumentss of micro-displacement measuring device 1 use amesdial 30, and amesdial 30 has reversed displacement measurement function, keep off
Plate 22 uses glass plate, so micro-displacement of the rail 2 in zero stress with rebound can measure.Micro-displacement measuring device 1
Can be mobile with rail 2, and this device pushes measuring instrument work, measuring instrument it is fixed on one device without by
The mobile influence of rail, that is, can reach the purpose of measurement.
Fixed device 10 further comprises and the falling of forming of the crossbeam 11 that is connected between two supporting legs 12 by supporting leg 12
U font fixing tool.The bottom of supporting leg 12 is fixed on the vertical bolt 6 of sleeper 5 by bolt 1, and fixed device 10 also wraps
It includes one end to be fixed on crossbeam 11, the strut 13 that the other end and amesdial 30 are fixed, strut 13 and crossbeam 11 are vertically connected to (use
Welding manner links together one end of supporting leg 12 and inverted u-shaped fixing tool in 90 °).The end of strut 13 passes through table folder
15 are fixedly connected with the fixed link 32 of amesdial 30, and the fixed link 32 of amesdial 30 is arranged in table folder 15, table folder 15 is screwed
Bolt, be fixed on amesdial 30 in table folder 15.
Before carrying out stress state measurement to rail 2, when micro-displacement measuring device 1 is initially installed, fixed device
The measuring staff 31 that relative distance between 10 and mobile device 20 meets amesdial 30 generates suitable initial displacement, in order to calibrated
Really measure the bouncing displacement of rail 2.
Rail-impacting block 3 be installed on rail 2 Longkou position (rail 2 will be truncated when measurement, close to truncated position be referred to as dragon
Mouthful), micro-displacement measuring device 1 and rail-impacting block 3 are when the installation site spacing on rail 2 is maintained between 98~102m, to steel
The measurement effect of rail micro-displacement is best.When the measurement length of rail 2 is greater than or equal to 500m, by least being installed every 500m
A set of micro-displacement measuring device 1 carries out stress state measurement.It is a set of by installing when the measurement length of rail 2 is less than 500m
Micro-displacement measuring device 1 carries out stress state measurement.
When carrying out the measurement of rail micro-displacement, no matter bouncing displacement is much, as long as amesdial 30 measures bouncing displacement
Then think that rail 2 is in zero stress state, and amesdial 30 is unmeasured then thinks that rail 2 is not up to zero stress shape to bouncing displacement
State.The bouncing displacement that amesdial 30 measures varies, this setting position with amesdial 30, rail-impacting block 3 setting position,
Quantity, the straight Qu Douyou very close relationship for hitting rail number and rail track of rail-impacting block 3 of rail-impacting block 3.When amesdial 30
When measuring bouncing displacement, rail-impacting block 3 stops hitting the rail 2 for being measured section.
The direction of displacement of rail 2 is consistent when the direction that mobile device 20 is directed toward fixed device 10 is hit with rail-impacting block 3.It is such as attached
Shown in Fig. 8, when rail-impacting block 3 imposes as shown in F in attached drawing impact force from left to right to rail 2, the direction of displacement of rail 2
The direction (from left to right) for being directed toward fixed device 10 with mobile device 20 is consistent.As shown in Fig. 9, when rail-impacting block 3 is applied to rail 2
When with the impact force from right to left as shown in F in attached drawing, the direction of displacement and mobile device 20 of rail 2 are directed toward fixed device 10
Direction (from right to left) is consistent.Mobile device 20 is fixed on rail 2 when using, can be with steel when carrying out rail microdisplacement measurement
The movement of rail 2 and move, when mobile device 20 is mobile to fixed device 10, amesdial 30 will generate reading, if fixation
When device 10 moves backward, it just will appear fixed device 10 and separated with mobile device 20, so as to cause not can be measured rail 2
Displacement.
The misalignment of rail 2 can be observed in real time by amesdial 30 for the micro-displacement measuring device 1 that embodiment 1 describes,
And can be clearly observed that reversed displacement when rail 2 rebounds, and make it possible the precise measurement of rail micro-displacement, it is non-
Often be conducive to when seamless track steel rail is laid with and is diffused, observe gapless line naked eyes when reaching zero stress state and be not easy to observe
The reversed micro-displacement arrived, to realize the accurate judgement of rail zero stress state.
