Abstract

The utility model discloses an integral contact-screen measuring ruler which is used in electrified railway. The integral contact-screen measuring ruler is composed of a main ruler and an auxiliary ruler, the main ruler can display levelness and environmental temperature and the main ruler is provided with a length scale and an angle scale, and the auxiliary ruler is provided with an altitude scale and a slope scale. The auxiliary ruler can rotate around the main ruler by 0-90 DEG. The integral contact-screen measuring ruler cooperates with an insulated vehicle ladder. The integral contact-screen measuring ruler can measure the static parameters of the contact line of a contact screen (height the value of a Chinese character 'zhi', pulling-out value), overhead crossing (position), locator (slope), overlap, compensator, isolation switch and section insulator. The integral contact-screen measuring ruler has the advantages of multi-function, convenience and flexibility.

Description

Integral contact-screen measuring ruler

The utility model relates to a kind of electrification railway contact net measuring instrument, particularly relates to a kind of contact net and installs, overhauls and use the composite measurement chi.

Contact net is the important component part of electric railway, is undertaking the traction power supply task of electric locomotive.In installing and keeping in repair, need measure to the parameter of items of equipment, existing survey instrument mainly contains: line bob, surveyor's staff, track forces, tape measure and insulation measuring staff, special calculator two classes, though can carry out the measurement of the multinomial equipment static parameter of contact net, measuring process is loaded down with trivial details, speed is slow.

The purpose of this utility model is that a kind of contact net composite measurement chi simple in structure, easy to use will be provided.Coordinated insulation car ladder, it can be measured contact net osculatory (highly, zigzag value or stagger), line trouble (position), steady arm (gradient), overlap, compensation system, disconnector, section insulator static parameter rapidly intuitively.

The purpose of this utility model realizes in the following manner: energy reveal competence, an environment temperature and the main scale that has length scale, an angle index are connected by one with a secondary chi that has altitude scale, gradient scale, make secondary chi rotate 90 degree around main scale; On the upper frame of insulation car ladder, make the mark of represent the block of bow collector of electric locomotive center line, on insulation car ladder underframe, make vertical with rail level and with the crossing mark of the upper frame outer edge of doing block of bow collector of electric locomotive center line mark.When measuring the osculatory static parameter, insulation car ladder is parked in the below that needs measuring point, the utility model main scale is placed on does on the car ladder frame of representing block of bow collector of electric locomotive center line mark, make main scale vertical mutually with secondary chi, secondary chi is leaned against on the osculatory, at this moment can read the distance that this osculatory departs from the block of bow collector of electric locomotive center by the intersection point of main scale and pantograph center line mark, the anchor point place is zigzag value (linear section) or stagger (curve section), can read height of contact wire by the intersection point of secondary chi and osculatory.Utilize this chi, but also slotted line trouble (position), steady arm (gradient), overlap, compensation system, disconnector, section insulator static parameter.

The utility model is an one because of the leveling ruler that catchments, ruler, so structure is simple especially, because of being used with insulation car ladder, need not to consider the circuit superelevation of outer rail during measurement simultaneously, so measurement data is accurate, directly perceived and speed is fast.

Concrete structure of the present utility model is provided by accompanying drawing 1 and following embodiment.

Fig. 1 is the principle assumption diagram of this utility model.

In conjunction with Fig. 1, this chi comprises a main scale (1), has level, environment temperature display (2), length scale (3), angle quarter (4) on it.A secondary chi (5) has altitude scale (6), gradient scale (7) on it, main scale (1) adopts stationary shaft (8) to be connected with secondary chi (5), and secondary chi (5) can rotate 90 degree around main scale (1) by axle (8).When main scale (1) and secondary chi (5) angle were 0, main scale (1) was integrated with secondary chi (5); When main scale (1) and secondary chi (5) angle are 90 when spending, main scale (1) is mutual vertical with secondary chi (5).Main scale (1) adopts same material to make with secondary chi (5), preferably adopts grooved hard aluminium alloy material, and its length is between 600～700 millimeters, and secondary chi (5) length is greater than 10～100 millimeters of main scale (1) length.Level, environment temperature display can adopt horizontal pearl, liquid-filled thermometer or electronic horizon, temperature indicator and main scale (1) cramp joint, and scale all adopts two-sided symmetrical scale.

Brief description is the operating position of this utility model once.

Fig. 2 measures the principle schematic of osculatory (highly, zigzag value or stagger) for utilizing this utility model.Among Fig. 2, (9) are the mark of the representative block of bow collector of electric locomotive center line done on insulation car ladder upper frame.

Fig. 3 is for utilizing the principle schematic of this utility model slotted line trouble (position).

In conjunction with Fig. 3, insulation car ladder is placed on the below that needs the survey line trouble, make the frame of doing block of bow collector of electric locomotive center line mark be in two contact intersection points under, can measure two osculatory intersection points with this chi and depart from the distance at pantograph center.Deduct range finding from being two osculatory intersection points with 1/2nd gauges in the position of frog, frog gauge (gauge in two) by insulation car ladder underframe marked (10) locate measurement.

Fig. 4 is a principle schematic of utilizing this utility model measurement and positioning gradient.

Fig. 5 utilizes this utility model to measure the principle schematic of disconnector.

Can directly measure the static parameter of overlap with the method for measuring osculatory (highly, zigzag value or stagger), also can utilize the measuring method of surveyor's staff, tape measure to measure.

Because of catchment leveling ruler, ruler of this utility model is one, the measuring method of utilizing surveyor's staff, tape measure is direct parameters such as metrophia compensation device, section insulator, dropper skew also.
