Description of drawings
Fig. 1 is structural representation of the present utility model.
As shown in Figure 1, hand dish 1, double-screw bolt 2, thread bush 3, framework 4, threaded flange 5, baffle plate 6, piston 7, back-moving spring 8, piston type high pressure cylinder 9, inflation inlet 10, scale 11, fixed head 12.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of general checking cylinder analogue means comprises framework 4, piston type high pressure cylinder 9, baffle plate 6 and can change the displacement adjustment device of baffle plate 6 positions.Displacement adjustment device has comprised hand dish 1, double-screw bolt 2, thread bush 3 and threaded flange 5; Piston type high pressure cylinder 9 comprises piston 7, at the back-moving spring 8 of piston type high pressure cylinder 9 inside be arranged on the inflation inlet 10 of piston type high pressure cylinder 9 one ends.
Framework 4 is welded by steel section, framework 4 one-piece constructions are casing shape, in framework 4, be provided with piston type high pressure cylinder 9, piston type high pressure cylinder 9 ends are fixed on the end face in the framework 4 by fixed head 12, be bolted on the side of framework 4 in piston type high pressure cylinder 9 sides, be provided with inflation inlet 10 in piston type high pressure cylinder 9 ends, in process of the test, air is by inflation inlet 10 turnover cylinders, be provided with back-moving spring 8 in the inside of piston type high pressure cylinder 9, when cylinder needs exhaust, but back-moving spring 8 auxiliary pistons 7 recover the original position, and gas is discharged from inflation inlet 10.Piston 7 one end the place aheads at piston type high pressure cylinder 9 are provided with baffle plate 6, and the change in location of baffle plate 6 is used for changing the range of piston 7, change the volume of cylinder by the range that changes piston 7.
Be welded with thread bush 3 at framework 4 one ends, double-screw bolt 2 is threaded in the thread bush 3, and double-screw bolt 2 passes framework 4, and two ends are positioned at framework 4 inside and outside both sides.Baffle plate 6 is fixed on the end of double-screw bolt 2 in framework 4 by threaded flange 5, threaded flange 5 screw thread rotation are on double-screw bolt 2, be fixedly connected with baffle plate 6 by a plurality of bolts, when test has just begun, because it is larger that the piston 7 of piston type high pressure cylinder 9 withstands on the pressure of baffle plate 6, threaded flange 5 plays the effect that buffering reduces pressure, and also available threaded flange 5 is finely tuned, by threaded flange 5 also conveniently replaced baffle plate 6.The end that double-screw bolt 2 is positioned at framework 4 outsides is equipped with hand dish 1, can drive double-screw bolt 2 in thread bush 3 interior rotations by shaking hand dish 1, thus the displacement of control baffle plate 6.Be provided with scale 11 at framework 4, scale 11 is arranged on the back of baffle plate 6, is used for the displacement of viewing hood, thus the volume size of accurate control piston formula high-pressure cylinder 9.
The volume size of piston type high pressure cylinder 9 is by its piston 7 controls in the general checking cylinder analogue means, and the larger volume of the displacement of piston 7 is larger, and the less volume of displacement is less.In the technical program, come the displacement of control piston 7 by baffle plate 6, cylinder is by inflation inlet 10 inflating pressures, and pushing piston 7, piston 7 withstand baffle plate 6 can't be continued to move, thereby has controlled the volume size of piston type high pressure cylinder 9.
When carrying out the work of train braking cylinder ground experiment, usually we only are concerned about the pressure of braking gas in the jar and the maximum volume of checking cylinder, so can replace the train braking cylinder of each model with general checking cylinder analogue means, the volume size that only needs to change checking cylinder by the displacement that changes baffle plate 6 just can.At the trial, manually shake hand dish 1, confirm required checking cylinder volume size by scale 11, begin test, general checking cylinder analogue means is connected in the test equipment, test inflationtime, each time point pressure change and the resulting pressure value.
Difference from Example 1 is, baffle plate 6 is connected not by threaded flange 5 with double-screw bolt 2, but is welded and fixed, and other schemes are identical with embodiment 1.
As mentioned above, given scheme content can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
