Description
Technical field
The utility model relates to a kind of survey instrument, and specifically a kind of terminal block pitch-row is measured specific purpose tool, is mainly used in the Measurement accuracy of electric system Overhaul site transformer lead terminal block, butterfly valve, ring flange equidimension and pitch-row.
Background technology
Electric power overhaul department, at Overhaul site, when sleeve pipe lead-in wire terminal block, butterfly valve and ring flange are changed, needs Measurement accuracy interface size, tape measure is often applied at scene or distance is compared in slide calliper rule measurement, cause measuring out of true, product processing does not meet maintenance requirement, so cause fixing, crimping is poorly sealed.Especially in the time that pitch-row is measured, ruler or tape measure error are larger.In addition, in normal operational inspection process, sometimes need non-contact measurement relative dimensions, carry out the management work of standby redundancy, conventional measuring method cannot meet the demands, and has following relatively distinct issues:
1, bushing shell for transformer lead-in wire terminal block, butterfly valve, the overall dimensions of ring flange and the measurement tape measure of pitch-row, measuring error is large.
2,, in equipment live operational process, cannot realize the non-contact measurement of relative dimensions.
Utility model content
The purpose of this utility model is to provide a kind of terminal block pitch-row measurement specific purpose tool that all kinds of terminal blocks, butterfly valve, ring flange size and pitch-row are accurately measured that meets.
The technical scheme in the invention for solving the technical problem is: terminal block pitch-row is measured specific purpose tool, comprise handle and the measuring head that is arranged on handle one end, described measuring head comprises two laterally card mark and longitudinal card marks, described horizontal card mark comprises a fixed card mark and a scalable card mark, and described longitudinal card is designated as scalable card mark.
As further technical scheme: be also provided with range finding looking glass and liquid crystal number screen on described measuring head.
As further technical scheme: described horizontal card mark and longitudinally card target top are equipped with infrared transmitter.
Compared with prior art, the utlity model has following beneficial effect:
1, apply mobile slide calliper rule principle, survey instrument is designed with three card marks, and one fixing, and two scalable, the measurement of different size in the scope that meets the demands.Scalable card indicates effect increases measurement range, contract measurement instrument volume.
2, digital display type survey measurements is intuitively accurate.
3, three cards are put on and are equipped with infrared transmitter, and infrared distance measurement at a distance, by Automatic Levelling, realizes non-contact measurement.
4, can meet the Measurement accuracy of terminal block, butterfly valve, ring flange equidimension and pitch-row simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model terminal block pitch-row is measured specific purpose tool;
Fig. 2 is the measuring principle figure of the utility model while measuring the round pieces such as circular butterfly valve and ring flange;
Levelling schematic diagram when Fig. 3 is the remote non-cpntact measurement of the utility model.
In figure: 1 handle, 2 scalable card marks, 3 fixed card marks, 4 infrared transmitters, 5 range finding looking glass, 6 liquid crystal number screens.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described:
As shown in Figure 1, terminal block pitch-row of the present utility model is measured specific purpose tool, comprise handle 1 and the measuring head that is arranged on handle 1 one end, described measuring head comprises two laterally card mark and longitudinal card marks, described horizontal card mark comprises a fixed card mark 3 and a scalable card mark 2, and described longitudinal card is designated as scalable card mark 2.
On described measuring head, be also provided with range finding looking glass 5 and liquid crystal number screen 6.
Range finding looking glass 5 adopts the principle of camera looking glass, the triangle frame of the range finding interior demonstration of looking glass 5 and actual card cursor position equal proportion, blocks cursor position by adjusting, and the interior triangle frame of range finding looking glass 5 can change thereupon, when measurement, the triangle frame and the testee that regulate actual card cursor position to make to find range in looking glass 5 coincide.While surveying air line distance, only need a limit of triangle frame to coincide, while measuring circle structure, in triangle frame, be connected to measured circle.
Liquid crystal number shield 6 measured holes apart from isoline apart from time show two laterally distances between card mark; While measuring circumference, block the distance between mark except showing laterally, can show other quantity information by internal calculation, as radius, girth, area etc.The principle of liquid crystal number screen 6 is equal to the liquid crystal number screen of existing digital display calliper, and its inner structure belongs to the known technology of various equivalent modifications, does not repeat them here.
Described horizontal card mark and longitudinally card target top are equipped with infrared transmitter 4.Infrared transmitter 4 is leveling units, when close-in measurement, without using infrared transmitter 4, when remote non-cpntact measurement, carries out levelling by infrared transmitter 4, and the triangle frame that makes to find range in looking glass 5 parallels with tested air line distance or circular configuration.
When interruption maintenance is measured, apply mobile slide calliper rule principle, the utility model is designed with three card marks, and one fixing, and two scalable, the measurement of different size in the scope that meets the demands.When measurement, will block mark accurately fixing, just can prepare data measured.Rectangle and pitch-row measure with two laterally card just mark can Measurement accuracy; While measuring circular butterfly valve and ring flange size, as shown in Figure 2, regulate two scalable card marks 2 simultaneously, keeping 3 lines is equilateral triangle, by closely accurate with measured workpiece clamping three card marks, connect equilateral triangle in round and survey disk diameter by interior being connected to, can show the geometric sense such as disk size and area calculating by digital display device.
When remote non-cpntact measurement, the infrared transmitter 4 that three cards are put on is all in running order, regulates card cursor position by range finding looking glass 5, makes card mark line and measuring object level, can realize telemeasurement.As shown in Figure 3, AB is tested air line distance, and DC is limit of triangle frame in looking glass, infrared distance sensor is equipped with at D, C two places, and when non-cpntact measurement, by the infrared distance measurement levelling of 2 of D, C, AD and BC are when equating, tested straight line is parallel with survey instrument, and now reading is effective.
Liquid crystal number screen 6, infrared transmitter 4 are equipped with corresponding power supply, switch etc.; as one of ordinary skilled in the art; completely can be as the case may be; the above-mentioned parts that needs are used specifically arrange; for ease of explanation and understand improvement feature of the present utility model; the related content of this part is no longer elaborated,, so it can not form impact to protection domain of the present utility model.
Except the technical characterictic described in instructions, all the other technical characterictics are those skilled in the art's known technology.
