Abstract
The utility model provides a portable vertical wheel-rail force loading device which comprises an upper supporting pole, a pressure sensor, an oil jack, a jack lever, a supporting base, pull poles, a rail holder, a fixation pole, wherein, the upper pole, the pressure sensor, the oil jack, the jack lever are connected from up to down sequentially in a line, the upper end of the upper supporting pole is connected to the center of the supporting base, and the two ends of the supporting base are connected to two pull poles via bolts, the other ends of the pull pole are connected to the rail holder by bolts, and the fixation pole is arranged between the lower end of the jack lever and the rail holder. The utility model is device for simulation of loading vertically on the practical steel rails and is mainly utilized for the marking on a wheel rail force detecting system and a rail weighing system.
Description
Technical field
The utility model relates to a kind of wheel track force loading device, specifically, relates to a kind of vertical wheel track force loading device that is used for the on-the-spot rail dynamometry of railway.
Background technology
The meausring apparatus of rolling stock is widely used to be track scale or dynamometry rail.These devices all will carry out periodic calibrating when Installation and Debugging and after the operation, owing to there is not unified demarcation measurer, all adopt counterweight car or locomotive to demarcate at present.
The shortcoming of utilizing counterweight car or locomotive to demarcate is: the load capacity of counterweight car wheel is subjected to the influence of track scale or the horizontal irregularity of dynamometry rail and causes the calibration result error, the allotment of counterweight car is subjected to the restriction of train marshalling list in addition, therefore needs a kind of portable wheel track force loading device and realizes rail is loaded.
The utility model content
The problem that the utility model solved provides a kind of vertical wheel track force loading device, and realization is simulated the on-the-spot rail of railway and applied vertical load, reduces calibrated error.
To achieve these goals, the utility model provides a kind of portable vertical wheel track force loading device.Portable vertical wheel track force loading device comprises upper support bar, pressure transducer, hydraulic jack, boosting-rod, supporting seat, pull bar, holds rail device, fixed bar, upper support bar, pressure transducer, hydraulic jack, boosting-rod are in turn connected into straight line from top to bottom, the upper end of upper support bar links to each other with the center of supporting seat, the two ends of supporting seat link to each other with two pull bars by pin respectively, the other end of pull bar by pin with hold the rail device and be connected, fixed bar is arranged on the boosting-rod lower end and holds between the rail device.
The lower end of described boosting-rod contacts with rail, and contact jaw is shaped as sphere.
Upper support bar, pressure transducer, hydraulic jack, boosting-rod becomes to connect into straight line successively, and it is vertical with rail, whole portable vertical wheel track force loading device is trapezoidal, supporting seat is parallel to rail, two pull bars respectively with hold the rail device and link to each other, constitute trapezoidal hypotenuse, hold rail device fastening rail, whole device is fixed on the rail, two fixed bars are separately positioned on two and hold between rail device and the boosting-rod lower end, the rail device of holding at two ends moves to the center when avoiding device that rail is loaded, and guarantees that simultaneously boosting-rod is vertical with rail, realizes rail is applied vertical load, pass through pressure transducer at last, convert force signal to electric signal,, show the size of acting force to make the input signal of display device.Thisly significantly reduced the error that timing signal produces because of horizontal irregularity by applying the method that vertical load demarcates.
After below in conjunction with accompanying drawing, embodiment the utility model being described in detail, other characteristics of the present utility model, advantage will be more obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the synoptic diagram of the utility model embodiment.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, upper support bar 1, pressure transducer 2, hydraulic jack 3, boosting-rod 4 are in turn connected into straight line, the upper end of upper support bar 1 links to each other with the center of supporting seat 5, the two ends of supporting seat 5 link to each other with two pull bars 6 by pin respectively, the other end of pull bar 6 by pin with hold rail device 7 and be connected, fixed bar 8 is arranged on boosting-rod 4 lower ends and holds between the rail device 7, and boosting-rod 4 lower ends contact with rail 9.
As Fig. 2, to hold rail device 7 rail 9 that links closely, then whole charger assembling is shaped, to hydraulic jack 3 imposed loads, acting force acts on downwards on the boosting-rod 4 by hydraulic jack 3, finally rail 9 is realized imposed load, meanwhile, acting force is upwards acted on the supporting seat 5 by upper support bar 1, the pull bar 6 that is connected with supporting seat 5 and hold rail device 7 and be subjected to acting force after, the trend that can oriented center moves, at this moment, fixed bar 8 is arranged on boosting-rod 4 lower ends and holds between the rail device 7, to holding rail device 7 and boosting-rod 4 plays fixing effect, avoided holding rail device 7 to the center move may, another effect of fixed bar 8 is to guarantee that boosting-rod 4 is vertical with rail 9, acting force is vertically acted on the rail 9, realize vertical value-added tax function, reduced the error that produces because of horizontal irregularity railway track 9, at last by pressure transducer 2, force signal is converted to electric signal, and the size of electric signal is directly proportional with the size of acting force, shows thereby be transferred to display device.
