Abstract
The invention discloses a retractable positioning rod for measurement, which is characterized in that the retractable positioning rod for measurement comprises a support rod, a probe harness, pulleys, a manual crank, a pull rope, an inclination transmitter and the like; the support rod is formed by two-stage round section rods (a primary rod and a secondary rod) in a sheathing way. The lifting action and the lowering action of the support rod are separately conducted. When the support rod is lifted up, the secondary rod is pulled through the pulleys and a steel belt; and by manually pulling the pull rope, the secondary rod is lowered down. Scales are additionally arranged on the primary rod and the traction steel belt to determine the length of the entire rod. The position of a measuring point is determined according to the length and the inclination. The device is portable, simple and easily controllable, the overhead positioning function is added, the measuring point movement operation is simplified, the testing accuracy is guaranteed and the operation efficiency is improved.
Description
Technical field
The present invention relates to a kind of built on stilts locating device that is applied in the experimental test field, be specially a kind of measurement with flexible backstay.
Background technology
The power station steam turbine group is in order to keep recycling of working medium, and the economy that improves unit reduces the carbon emission amount, need the steam discharge after the generating be cooled off, and the hinterland is final heat eliminating medium to ventilate, and the ventilation situation is significant to unit.
In recent years, along with the development of situation, the production scene is outside, inner transforms ventilation condition to the Steam Turbine cooling device to carry out the requirement of direct test analysis urgent further.On-the-spot aerated area is in order to reduce windage, and generally openr spaciousness should not be installed fixedly measuring point; And test and research in order to carry out ventilation condition are chosen the intensity test of a certain cross section or alternate manner to layout, and the volume coordinate of a position is accurately located; And present shaped article is investigated, most of product adopts multistage loop bar structure, does not all possess positioning function; And catanator is comparatively complicated, is inappropriate for and carries out assignment test work.For this reason, need a kind of can the convenience exactly to measure the equipment tool of ventilation condition by being scheduled to layout.
Summary of the invention
The object of the invention just is to provide a kind of measurement with flexible backstay; To solve by the intensive difficult problem of measuring point and the problem that point position is needed accurate location and writes down of being provided with of certain space layout; The present invention has easily and locatees, is shifted, and improves operating efficiency effectively, guarantees the simultaneity of test best; Reduce the interference of air eddy, have practicality and characteristics such as accurate test result.
The present invention adopts as follows
Technical scheme:
The present invention includes hack lever, probe harness, pulley blocks, inclination angle transmitter; Said hack lever is made up of the son, the female bar that adopt the round pole structure of two-stage; At the sub bar top probe harness is installed; Said pulley blocks comprises pulley, bearing, turning handle, traction steel band and the stay cord that is provided on the primary and secondary sleeve pipe, and said pulley is installed in the outer bottom of female bar, and Bearing Installation is in female bar outer upper ends; The traction steel band passes that crack is located between pulley and bearing between son, female bar; The one of which end is fixed on the sub bar bottom, and the other end is fixed on the turning handle, and turning handle is fitted on the pulley; Said stay cord one end is fixed on the sub bar bottom, and the other end stretches out outside female bar; All add scale at female bar outer wall with drawing on the steel band; Can confirm that the inclination angle transmitter at angle of inclination is installed in female bar bottom.
Of the present invention
Beneficial effectFor: 1. be suitable for mobile operating, be easy to carry; 2. by high-precision requirement configured length and measurement of angle, satisfy the requirement of research and production measuring accuracy; 3. catanator is simple, reduces general assembly (TW), is suitable for manual work to use and handle; 4. steel band exposed parts two ends are equipped with stop, avoid invar band sideslip, the error that causes such as unsettled.This device is mainly used in the test job of scientific research, mechanism for testing, also can be used for similar operation occasion.
Use the present invention, avoided the complicated heavy of test auxiliary facility, light portable, simple and easy to control has increased built on stilts positioning function, has simplified the measuring point operation of moving about, and has guaranteed measuring accuracy, has improved operating efficiency.
The present invention is applicable to scientific research test needs, other engineering field of also moving applicable to light-duty load situation.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
Embodiment
It comprises hack lever, probe harness 3, pulley blocks, inclination angle transmitter 7 to a kind of measurement of the embodiment of the invention with flexible backstay shown in accompanying drawing; Said hack lever adopts aluminum alloy materials to process, and in order to take into account portability and practicality, is made up of the son, the female bar 2,1 that adopt the round pole sleeve structure of two-stage and forms.From simplify most, practical purpose, hack lever ascending, descending action is separately carried out, and rises hack lever to be accomplished by pulley blocks; Use traction steel band 5 pulling sub bars 2 in the pulley blocks; Traction steel band 5 one ends are fixed on sub bar 2 bottoms, place between son, female bar 2,1 crack female bar 1 top dress bearing 4; Traction steel band 5 is close to female bar 1 outer wall after bearing 4 break-ins; Be fixed in the rotating shaft of turning handle, turning handle is assemblied on the pulley 6 that is positioned at 1 time bottom of female bar, can sub bar 2 be promoted through turning handle; The step-down operation of sub bar 2: the stay cord 8 through being fixed on sub bar 2 bottoms passes from female bar 1 afterbody, pulls these stay cord 8 sub bars 2 and descends.Female bar 2 outer walls all add scale with drawing on the steel band 5, and the walk scale on the traction steel band 5 can be confirmed to put in order pole length with the nonadjustable signal on female pipe 1, and bearing accuracy is a scale divisions, can be to the millimeter level.The inclination angle transmitter is installed in female bar bottom, can measure the angle of expansion link.Like this, confirm point position with length and inclination angle, the measurement scheme set can be realized in variation length and inclination angle as required.
