Description
Technical field
The utility model relates to a kind of parts checkout equipment of electric locomotive, refers in particular to a kind of static characteristics tester of block of bow collector of electric locomotive hand-held, is mainly used in the static characteristics test of block of bow collector of electric locomotive.
Background technology
Pantograph is the power supply source of electric locomotive operation, electric locomotive is after the power supply network by ground obtains power supply again by pantograph, offer the electric locomotive each several part then as power supply, therefore whether pantograph can obtain stable power from electrical network, is to ensure whether whole electrical locomotive power stablizes normal basic link.And ensure pantograph from the ground electrical network obtain stabilized power source the most basic be the contact quality that will guarantee pantograph and grid power transmission line.So the contact performance of pantograph and grid power transmission line is detected in service often want of electric locomotive.At present, be to adopt manual mode to the detection overwhelming majority of pantograph, promptly install again after adjusting, and also need manual setting after installing by manually pantograph being pulled down to detect, waste time and energy.Not only the cycle long, and precision is not high yet.
At above-mentioned inconvenience, those skilled in the art have carried out a series of development research, wherein representationally are:
1, the patent No. is: ZL00200843.2, name is called: pantograph tester, this kind pantograph tester have proposed a kind of portable pantograph detector of online detection, are made up of microcomputer, cabinet, motor, drum, sensor, wire rope etc.It provides a kind of uniform motion can guarantee the pantograph lifting time, can truly reflect the full-automatic testing instrument of the continuous variation relation of pantograph contact pressure and ascending, descending bow height.But this kind checkout equipment is too complicated, and operation is also inconvenient.Therefore use and receive restriction.
2, the patent No. is: CN200710050923.8, name is called: a kind of on-line checkout equipment for contact pressure of motorcycle pantograph, track one side that this patent proposes the outer heel post of its track is fixed with support, the elevating screw bottom is fixed on the bearing inner race of support, and pass worktable erecting frame and workbench successively, cooperate with lifting nut on the erecting frame; Workbench is fixed on the erecting frame; Be provided with pull pressure sensor near above the workbench of stud sides, the steel cable that links to each other with this sensor is passed down through workbench and erecting frame links to each other with an end of nearside level insulation; The other end of level insulation links to each other with distally level insulation, and junction and vertically insulated sub-bottom are hinged, and vertically insulated son is upward through workbench, is fixed on the workbench; The other end of distally level insulation connects the contact net clip downwards; Pull pressure sensor is electrically connected with data processing and opertaing device.Though the online detection of dynamic of this equipment energy, but still exist equipment too complicated, so that volume is still excessive, and operation still is not very convenient.
Also have in addition much and be engaged in the research of pantograph tension-compression sensor specially, as number of patent application is CN200410046818.3, name is called: the patented claim of the special-purpose force transducer of DSA series pantograph, be exactly one of them, this patent relates to the special-purpose force transducer of a kind of DSA series pantograph, it is made up of spring lever and tension and compression ring type sensor, is the combination of a kind of DSA series pantograph support inner spring bar and tension and compression ring force sensor.It comprises; A) spring lever of forming by dop (1), connecting rod (2) and (6).B) elastic body (3); C) sensitive components (4).Sensitive components can be a strainometer, or other can be converted to elastomeric distortion the device of electric signal.And for example number of patent application is CN200410046816.4, and name is called: the patented claim of special-purpose force transducer of imitative 8K pantograph and force guide device, the diameter that proposes sensor can not be according to general cartridge type sensor design with the ratio of height.Be to guarantee that precision, sensor adopt specially designed joint skirt or the method that sensor and pantograph collector head spring precision is bonding to improve contact conditions.Strainometer adopts symmetry to paste, and forms resistance bridge.Force guide device adopts the former parts on the pantograph, the vertical pivot in the spring case.But these patents are all less than the concrete volume that proposes how further to dwindle detector, so that operating personnel's detection of getting on the bus that is easy to carry.
Therefore necessary this is improved.
The utility model content
This patent utility model problem to be solved is: at the deficiency of existing contact pressure of motorcycle pantograph detection mode and equipment thereof, it is littler to propose a kind of volume, hand-held contact pressure of motorcycle pantograph detector more convenient to operate.
The purpose of this utility model is achieved through the following technical solutions: a kind of contact pressure of motorcycle pantograph detector, be hand-held motorcycle pantograph detector, comprise a housing, directly be provided with display screen on the front of housing, case panel below the display screen is provided with operation push-button, operation push-button is the thin film switch keyboard, and total six press keys: there are four keys in upper and lower, left and right on the left side on a circular pattern; There is setting on the right, confirms two keys, with these keys information such as test parameter is set.Crown center position at housing is provided with the load-bearing drag hook, be positioned at housing have a S shape tension-compression sensor directly and the load-bearing drag hook link together; On the both sides of housing, be with simultaneously a hand-held handle, hand-held handle can slide up and down in the side of housing, the upper end and the load-bearing drag hook of S shape tension-compression sensor link together, the bottom of S shape tension-compression sensor and the hand-held handle of housing join, and can be when shaking hands down slippage hand-held, drive tension-compression sensor, S shape tension-compression sensor will produce pressure signal, handle simultaneously pressure signal transmission for the control chip (single-chip microcomputer) in the housing, show test function and result by liquid crystal display, carry out the online detection of relevant pantograph contact pressure.Side at hand-held handle also is provided with testing button, and the power supply of testing button control detection instrument is the time-delay closing switch, whenever will carry out the test of a stipulated time length by testing button next time.
