Description
Technical field
The present invention relates to rail clip applied technical field, be specifically related to a kind of frock for elastic-strip pressure detection.
Background technology
DTVI2 type spring is mainly used in the fastening of rail of subway, and matched rail clip includes Insulation rail distance keeper, rubber
Backing plate and preburied iron base etc..DTVI2 type spring belongs to non-bolt fastener, it have compared with I type and II type spring buckle press big,
Good springiness, keep that gauge ability is strong, it is few to withhold parts, handling simplicity, and the advantage such as maintenance work amount is few.Owing to there being bolt
Fastener can regulate elastic-strip pressure by adjusting nut, and non-bolt fastener can not regulate himself buckle press.Therefore
Self buckle press size of DTVI2 type spring seems most important.General buckle press is not also had to detect in spring field at present
Equipment, and currently used equipment operation complexity, be unfavorable for a fairly large number of detection.
Summary of the invention
The present invention provides a kind of simple in construction, easy to operate and can guarantee that the elastic-strip pressure detection work of experiment accuracy
Dress.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of frock for elastic-strip pressure detection, including pedestal and the clamping device that is arranged on this pedestal with add carrier aircraft
Structure, is connected by sensor between this clamping device with load maintainer, described pedestal is provided with for by standard assembled state
That installs spring withholds bearing, and described clamping device is for clamping the toe-end of spring, and described load maintainer applies to clamping device
Being perpendicular to pedestal load upwards, described sensor is used for measuring this load.
Further, described clamping device includes pull bar, a pair connecting plate and a pair pulling claw, one end of described pull bar and institute
State sensor connect, one end of the other end of pull bar and two connecting plates is hinged, the other end of two connecting plates respectively with two
One end of pulling claw is hinged, and the other end of two pulling claws is mutually hinged.
Preferably, the lower end of two described pulling claws forms a semi-enclosed circular arc, for clamping the toe-end of spring.
Further, described load maintainer includes lever and the jack being arranged on pedestal, the push rod of this jack
Hinged with one end of lever by top briquetting, the other end of described lever is cut with scissors with the support bar being arranged on pedestal by pad briquetting
Connecing, the middle part of described lever is hinged with described sensor by connecting rod.
From above technical scheme, when the present invention simulates spring application, the situation of buckle press, is assembled spring by standard
State is arranged on withholds on bearing, makes pulling claw clamp the toe-end of spring, promotes spring by jack, thus measures spring
Buckle press, more intuitively, simply, can simulate situation when spring uses, it is ensured that the accuracy of experimental data.

Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present invention is described in detail.
As it is shown in figure 1, described frock includes pedestal 10, clamping device 20, load maintainer 30 and for connecting clamping machine
The sensor 40 of structure and load maintainer, wherein pedestal is arranged in concrete block 70 by bolt, and its surface configuration is withheld and propped up
Seat 50 and support bar 11, described in withhold bearing 50 for installing spring 60, withhold size and the matching used ferrum of spring of bearing
The doorway dimension of backing plate is consistent, and this spring is in the use state that standard assembles, and described support bar 11 is for supporting loading mechanism.
Described clamping device 20 clamps the toe-end of this spring, and load maintainer 30 applies to be perpendicular to pedestal 10 lotus upwards to clamping device
Carrying, 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 connecting plate 22 and a pair pulling claw 23, one end of described pull bar and biography
Sensor 40 connects, and one end of the other end of pull bar and two connecting plates is hinged, and the other end of two connecting plates draws 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.Hinged by connecting plate 22 so that clamping device in the vertical direction is adjustable, it is adaptable to multiple
The spring of type, adds the versatility of product.
Described load maintainer 30 includes lever 31 and the jack 32 being arranged on pedestal 10, and the push rod of this jack leads to
Crossing top briquetting 33 hinged with one end of lever 31, the other end of described lever 31 is by pad briquetting 34 and propping up of being arranged on pedestal
Strut 11 is hinged, and the middle part of described lever 31 is hinged with described sensor 40 by connecting rod 35, increases by the way of hinged
The precision of detection.During detection, jack 32 to clamping device 20 to apply to be perpendicular to the load of pedestal, makes spring 60 toe-end lower surface
And withholding the distance producing 0.1mm between bearing 50, the size now applying power is the buckle press of spring.
The above embodiment is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the those of ordinary skill in the art technical side to the present invention
