The utility model discloses the circumstances of the power of withholding was installed the bullet strip on withholding the support according to standard equipment state when simulation bullet strip was used, made the toe -end who draws the claw to grasp the bullet strip, promoted the bullet strip through the jack to the power of withholding of survey bullet strip, it is more directly perceived, simple, can simulate the condition of bullet strip when using, guaranteed the accuracy of experimental data.
Description
Technical field
The utility model is related to rail clip applied technical field and in particular to a kind of be applied to what elastic-strip pressure was tested
Frock.
Background technology
Dtvi2 type spring is mainly used in the fastening of rail of subway, matched rail clip include Insulation rail distance keeper,
Rubber mat plate and preburied iron base etc..Dtvi2 type spring belongs to non-bolt fastener, and it is had compared with i type and ii type spring withholds
The advantages of power is big, elasticity is good, holding gauge ability is strong, it is few to withhold parts, handling are easy, and maintenance work amount is few.Due to
There is bolt fastening can adjust elastic-strip pressure by adjusting nut, and non-bolt fastener is to adjust its own buckle press
's.Therefore dtvi2 type spring itself buckle press size seems most important.Also there is no general withholding at present in spring field
Power testing equipment, and the current equipment operation using is complicated, is unfavorable for a fairly large number of detection.
Utility model content
The utility model provides a kind of structure simple, elastic-strip pressure detection that is easy to operate and can guarantee that experiment accuracy
Frock.
For solving above-mentioned technical problem, the utility model adopts the following technical scheme that
A kind of frock being applied to elastic-strip pressure experiment, include pedestal and be arranged on clamping device on this pedestal with
Load maintainer, is connected by sensor between this clamping device and load maintainer, and described pedestal is provided with for by standard group
What dress state installed spring withholds bearing, and described clamping device is used for clamping the toe-end of spring, and described load maintainer is to clamping machine
Structure applies perpendicular to pedestal load upwards, and described sensor is used for measuring this load.
Described clamping device includes pull bar, a pair of connecting plate and a pair of pulling claw, one end of described pull bar and described sensor
Connect, the other end of pull bar is hinged with one end of two connecting plates, the other end of two connecting plates respectively with two pulling claws one
End is hinged, and the other end of two pulling claws is mutually hinged.
Described load maintainer includes lever and is arranged on jack on pedestal, and the push rod of this jack passes through top pressure block
Hinged with one end of lever, the other end of described lever is hinged with the support bar being arranged on pedestal by pad briquetting, described thick stick
It is hinged with described sensor that connecting rod is passed through at the middle part of bar.
Preferably, the lower end of two described pulling claws forms a semi-enclosed circular arc, for clamping the toe-end of spring.
From above technical scheme, when the utility model simulates spring application, the situation of buckle press, spring is pressed standard
Assembled state is arranged on to be withheld on bearing, makes pulling claw clamp the toe-end of spring, lifts spring by jack, thus measuring bullet
The buckle press of bar, more intuitively, simply, situation when spring uses can simulated is it is ensured that the accuracy of experimental data.

Specific embodiment
Below in conjunction with the accompanying drawings a kind of preferred embodiment of the present utility model is described in detail.
As shown in figure 1, described frock includes pedestal 10, clamping device 20, load maintainer 30 and is used for connecting clamping machine
The sensor 40 of structure and load maintainer, wherein pedestal are arranged in concrete block 70 by bolt, and its surface is provided with to withhold and props up
Seat 50 and support bar 11, described bearing 50 of withholding is used for installing spring 60, withholds size and the matching used iron of spring of bearing
The doorway dimension of backing plate is consistent, and this spring is in the use state of standard assembling, and described support bar 11 is used for supporting loading mechanism.
Described clamping device 20 clamps the toe-end of this spring, and load maintainer 30 applies perpendicular to pedestal 10 lotus upwards to clamping device
Carry, make spring 60 toe-end lower surface and withhold generation gap between bearing 50, now the size of applying power measured by sensor 40
It is the buckle press of spring.
Described clamping device 20 includes pull bar 21, a pair of connecting plate 22 and a pair of pulling claw 23, one end of described pull bar and biography
Sensor 40 connects, and the other end of pull bar is hinged with one end of two connecting plates, and the other end of two connecting plates is drawn with two respectively
One end of pawl is hinged, and the other end of two pulling claws is mutually hinged, and the lower end of two described pulling claws forms a semi-enclosed circular arc,
For clamping the toe-end of spring.By the hinged of connecting plate 22 so that clamping device in the vertical direction adjustable it is adaptable to multiple
The spring of type, increased the versatility of product.
Described load maintainer 30 includes lever 31 and is arranged on jack 32 on pedestal 10, and the push rod of this jack leads to
Cross top pressure block 33 hinged with one end of lever 31, the other end of described lever 31 passes through to pad briquetting 34 and is arranged on propping up on pedestal
Strut 11 is hinged, and the middle part of described lever 31 is hinged with described sensor 40 by connecting rod 35, is increased by way of hinged
The precision of detection.During detection, jack 32 applies the load perpendicular to pedestal to clamping device 20, makes spring 60 toe-end lower surface
And withhold the distance producing 0.1mm between bearing 50, now the size of applying power is the buckle press of spring.
The above embodiment is only preferred embodiment of the present utility model to be described, not to this practicality
New scope is defined, and on the premise of without departing from the utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the guarantor that claims of the present utility model determine
In the range of shield.
