Electric locomotive pantagraph current collector Static Contact force measuring device
The present invention relates to a kind of electric locomotive pantagraph current collector Static Contact force measuring device, belong to mechanical measuring device technical field.
Pantagraph current collector is arranged on after in electric locomotive, needs to carry out testing and debugging to the Static Contact power on pantagraph current collector at the scene, makes it be in specialized range, therefore needs the static force of a measurement mechanism to pantagraph current collector to measure.
At present, all use a small spring to claim when measuring Static Contact power at the scene, its measuring accuracy is not high, and consumes very much the muscle power of tester.
Summary of the invention
For overcoming the deficiency that prior art exists, solve the problems of the technologies described above, the invention provides a kind of equipment light, operation is simple, the electric locomotive pantagraph current collector Static Contact force measuring device that degree of accuracy is high.
The present invention adopts following technical scheme: a kind of electric locomotive pantagraph current collector Static Contact force measuring device, it is characterized in that, comprise upper bracket, lower carriage, movable support platform, described movable support platform is arranged between described upper bracket and described lower carriage, smooth bar is connected with between described upper bracket and described lower carriage, rotatable screw mandrel, rule, protective cover, described smooth bar, described rotatable screw mandrel, described rule, described protective cover is all through described movable support platform, the top of described rotatable screw mandrel is fixedly installed pivoting lever, described rule is used for showing the height of pantagraph current collector apart from orbit plane.
Preferably, upper bracket is provided with level meter, level meter is used for the horizontality of display device; The side of upper bracket is provided with screw mandrel backstop, and screw mandrel backstop is used for stoping rotatable screw mandrel to rotate.
Preferably, lower carriage runs through and is provided with horizon bar, and the outer setting of horizon bar has track fixture block, and track fixture block is two, be used for by fixing for this device in orbit.
Preferably, movable support platform is fixedly installed pressure transducer, display, movable support platform applies pressure to pantagraph current collector slide plate, utilizes pressure transducer to produce pressure signal, judges pantagraph current collector Static Contact power size by the change value of pressure of display.
Preferably, pantagraph current collector comprises contact pantagraph current collector, lower contact pantagraph current collector.
The beneficial effect that the present invention reaches: (1), compared with tradition weight beam metering system, improves measuring accuracy; (2) tester's measurement is made to get up more laborsaving, convenient; (3) usability is comparatively strong, can be common to the measurement of current several different pantagraph current collector.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication marked in figure: 1-pressure transducer, 2-display, 3-horizon bar, 4-smooth bar, the rotatable screw mandrel of 5-, 6-movable support platform, 7-pivoting lever, 8-upper bracket, 9-lower carriage, 10-level meter, 11-rule, 12-protective cover, 13-screw mandrel backstop, 14-track fixture block.
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 is structural representation of the present invention, the present invention proposes a kind of electric locomotive pantagraph current collector Static Contact force measuring device, comprise pressure transducer 1, display 2, horizon bar 3, smooth bar 4, rotatable screw mandrel 5, movable support platform 6, pivoting lever 7, upper bracket 8, lower carriage 9, level meter 10, rule 11, protective cover 12, screw mandrel backstop 13, track fixture block 14, form the electric locomotive pantagraph current collector Static Contact force measuring system of complete set.
Specific works process of the present invention: first, is put in electric locomotive pantagraph current collector side by this device, fixed in orbit by this device, move this device make pressure transducer 1 be positioned at directly over pantagraph current collector along horizon bar 3 by track fixture block 14, then pivoting lever 7, make the movable support platform 6 at pressure transducer 1 place slowly near shoegear, the effect of two smooth bars 4 keeps movable support platform 6 moving up and down maintenance balance in process, when pressure transducer 1 does not contact with shoegear, reading above display 2 is 0, after firm contact, reading becomes rapidly greatly (now shoegear does not move), slowly uniform speed slow rotates pivoting lever 7 again, movable support platform 6 is made to continue to move down, when shoegear by static after setting in motion, observe the scale on rule 11, when the scale of rule 11 meets pantagraph current collector adjustment height, tighten screw mandrel backstop 13 and ensure that rotatable screw mandrel 5 is motionless, reading now on display 2 is that pantagraph current collector is subject to flow contact, finally, contrast contact standard value, regulates pantagraph current collector, makes pantagraph current collector contact meet standard-required by repeated measurement and adjustment.
Measuring following contact pantagraph current collector static force is example, if measure upper contact pantagraph current collector static force, only pressure transducer (1) need be installed conversely, and upward, all the other are all the same, highly versatile for measuring surface.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
