Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
As Fig. 1, shown in Fig. 2, a kind of small-sized spirit-leveling instrument being convenient to regulate, comprise pedestal 1, by being rotatably connected on the spirit-leveling instrument body 2 of pedestal upper surface perpendicular to the vertical axes of pedestal upper surface, and be arranged on the connecting bottom board 3 of pedestal bottom, telescope for measuring is set in spirit-leveling instrument body, spirit-leveling instrument rear body arranges one for monitoring the circular bubble 41 of initial adjustment programmed level degree, spirit-leveling instrument body also needs arrange a micro-spiral 5 that inclines for accurate adjustment program, and the pipe level 42 parallel with collimation axis is set in the side of spirit-leveling instrument body, to monitor depth of parallelism during accurate adjustment program.Just debug to complete efficiently and easily, as shown in Figure 3, Figure 4, we can arrange a spherical hollow space 31 in the center of connecting bottom board, the upper and lower surface of the through connecting bottom board in both sides up and down of this spherical hollow space, thus make spherical hollow space be cydariform small in the end and big in the middle.Arrange a discoid slider pad 32 in spherical hollow space, the lateral surface of slider pad is the sphere with spherical hollow space adaptation, thus make slider pad can in spherical hollow space 360 degree of all-direction rotations.The center of slider pad arranges one perpendicular to the connection circular hole 321 of upper and lower surface, one swing arm 33 is vertically threaded on the lower surface of pedestal through after the connection circular hole of slider pad from bottom to up, swing arm arranges the stop nut 35 of the slider pad that reclines being positioned at slider pad upper position, swing arm arranges the spacing ring 331 of slider pad of reclining being positioned at slider pad lower position, thus makes axially spacing at swing arm of slider pad.That is, spirit-leveling instrument body now and the weight of pedestal all pass to slider pad by swing arm, and are in a kind of quick condition.In addition, arrange a spherical correction weight 34 in the lower end of swing arm, and the edge of connecting bottom board upper surface arranges at least three set screw 36, preferably, the quantity of set screw is four.When we unscrew set screw, the upper end of set screw can be resisted against on the lower surface of pedestal.At the lower surface of connecting bottom board, three telescoping support pin 9 are set around spherical hollow space, thus make swing arm be positioned at the centre of telescoping support pin.
During measurement, after we have set up telescoping support pin, we need set screw to be first screwed in connecting bottom board, to make itself and pedestal be separated, like this, pedestal and spirit-leveling instrument body can be in quick condition, and now swing arm automatically adjusts to pedal line position under the Action of Gravity Field correcting weight, thus makes spirit-leveling instrument ontology alignment to horizontality.We only need turn set screw successively lightly like this, make the upper end of set screw against on the lower surface of pedestal, the position of spirit-leveling instrument body can be made to fix, thus complete the first of levelness and debug, circular bubble then can be used for the monitoring of just timing, to guarantee the accuracy of just debugging.Then namely accurate adjustment program is carried out by micro-spiral that inclines, till the bubble of pipe level is placed in the middle.It should be noted that, in order to ensure initial adjustment precision, we should make swing arm pass pedestal and spirit-leveling instrument body center of gravity integrally, and telescopical collimation axis is arranged to parallel with the lower surface of pedestal, can guarantee in a free state like this, swing arm can adjust to pedal line position automatically, can not produce slight inclination because of the bias of spirit-leveling instrument body gravity.In addition, we also sphere can be arranged latticed lubrication groove outside slider pad, be coated with lubricant grease simultaneously, to reduce friction force when slider pad rotates in spherical hollow space, guarantee that swing arm can adjust to pedal line position completely in lubrication groove.And bulb can be arranged in the upper end that set screw exposes connecting bottom board, and hexagonal rotation section is set at the spiro rod section of set screw, so that it is by tool into rotation such as spanners.
For the ease of the installation of slider pad, we need to arrange two at the upper surface of connecting bottom board equally spacedly around the axis that spherical hollow space is vertical and insert groove 311, that is, two center lines of inserting groove are positioned at the diametric(al) of spherical hollow space, the medial surface of inserting groove is connected with spherical hollow space and forms opening shape, the lateral surface of inserting groove is the face of cylinder that diameter is equal with the spherical diameter of spherical hollow space, this lateral surface extends internally until tangent with the sphere of spherical hollow space along the vertical axis of spherical hollow space, and the width of inserting groove should be greater than the thickness of slider pad.Like this, when we need install time, can first make discoid slider pad and base-plates surface perpendicular, now slider pad can be put into two and insert in groove; When slider pad to insert in groove move to bottom time, sphere outside slider pad and the sphere of spherical hollow space fit, and the centre of sphere of two spheres overlaps, and slider pad is rotated 90 degree by again, make it parallel with pedestal, slider pad now can be spacing in spherical hollow space; Then we again by swing arm from bottom to up through the connection circular hole on slider pad, and the spacing ring of swing arm is reclined slider pad, stop nut of then screwing in the upper end of swing arm, can make swing arm axial limiting on slider pad; Finally again swing arm is threaded on the lower surface of pedestal.
It should be noted that, we can be connected one end and to be first threaded a back nut on swing arm with pedestal, this back nut is is integrally connected and composed vertically by hexagonal locking end and discoidal supported end, like this, after swing arm is connected with base thread, we are by hexagonal locking end locking back nut, make the circular end face of its supported end tightly against the lower surface of pedestal, like this, the self-locking of swing arm can be realized on the one hand, it is avoided to loosen voluntarily, be conducive to the verticality improving swing arm and pedestal lower surface simultaneously, avoid reducing the precision of just debugging because of the deflection of swing arm.
In addition, in order to improve the precision of accurate adjustment program, we also can arrange the axially extended distance rod 6 along telescope collimation axis respectively in the forward and backward side of pedestal, the distance rod of the forward and backward side of pedestal is coaxially arranged and be hinged on pedestal respectively by detachable hinge, and the pivot center of detachable hinge should be horizontally disposed with, thus distance rod can be swung up and down in the perpendicular of fore-and-aft direction, and can dismounting easily.In addition, arrange adjustable stem 8 straight up and support bar 7 straight down in the outer end of distance rod respectively, the lower end of support bar and ground touch, thus form reliable support to distance rod.And adjustable stem is flat rod, adjustable stem arranges vertical groove in the middle of the sidewall of spirit-leveling instrument body, transparent senior executive 81 such as grade is embedded in groove, waiting bottom senior executive on two distance rods is connected by plastic flexible pipe, Deng filling red liquid in senior executive, wait the calibrated scale pipe shaft of senior executive being arranged and can show liquid level.
In use, the first of collimation axis levelness that first can complete spirit-leveling instrument body is in the manner aforesaid debugged in the present invention.Then we in the front and rear sides of pedestal respectively by the hinged distance rod of detachable hinge, then, telescope is sighted the senior executive such as grade on the adjustable stem of front side, and read corresponding calibrated scale value, calibrated scale value in this calibrated scale value and these senior executives shown by liquid level is compared, the first difference of the contour intraluminal fluid face height of collimation axis and front side can be obtained; Then spirit-leveling instrument body is rotated 180 degree, the adjustable stem making telescope sight on rear side of pedestal waits senior executive, and read corresponding calibrated scale value, calibrated scale value shown by the contour intraluminal fluid face of this calibrated scale value and rear side is compared, the second difference of the contour intraluminal fluid face height of collimation axis and rear side can be obtained.Because the liquid in the senior executives such as front and back is communicated with, therefore its liquid level is completely the same, when collimation axis is in horizontality, above-mentioned first difference and the second difference should be completely the same, otherwise, if inconsistent, then fine-tuning micro-spiral that inclines, and then observe and record the first difference and the second difference, until first, second difference is identical, accurate adjustment program can be completed, make collimation axis keep horizontality.Certainly, the distance rod of front and back preferably can be arranged to the length of one meter, so that the calculating of collimation axis parallelism error and adjustment.
For the ease of the liquid level in the senior executives such as observation, as shown in Figure 7, we can arrange columniform indicator dog 82 on the liquid level waiting senior executive, indicator dog can be arranged to redness, its upper surface is a plane, thus can calibrated scale on the senior executive such as clear accurately comparison, accurately to read liquid level.
It should be noted that, wait the upper end of senior executive to open, thus the lifting being convenient to liquid in pipe is floated, we are when needs are measured, can by liquid by waiting in the senior executives such as the opening injection of senior executive upper end.In addition, after completing the accurate adjustment program of levelness, we should remove the distance rod of both sides before and after pedestal in time, so that spirit-leveling instrument starts the measurement to needing measurement point.
For ease of storage, distance rod can adopt stretching structure, and particularly, distance rod comprises some telescopic tubes 61 connected together from the inside to the outside, and the xsect of telescopic tube is rectangular, to avoid producing relative rotation between each telescopic tube.In distance rod, the tail end of outmost telescopic tube is connected with pedestal, in distance rod, the both sides up and down of innermost telescopic tube front end arrange a connecting insertion 62 respectively, adjustable stem is plugged in the connecting insertion of upside, and support bar is then plugged in the connecting insertion of downside.In addition, as shown in Figure 5, the tail end madial wall of each telescopic tube laterally arranges the positioning strip 63 with the axis perpendicular of telescopic tube, and wear a spacing steel wire 64 in distance rod, spacing steel wire is connected with the positioning strip on each telescopic tube of distance rod successively.Thus the displacement that can limit between adjacent two telescopic tubes, and finally control the length of distance rod exactly.When we need storage, the telescopic tube of distance rod can overlappedly be socketed, and now, flexible spacing steel wire correspondingly can bend contraction; And when needing to measure, then telescopic tube can be pulled out successively, and accurately limit length by spacing steel wire.
Further, as shown in Figure 6, support bar comprise dock up and down upper stay tube 71, lower stay tube 72 and up and down two ends be set in upper and lower stay tube respectively and mutually dock regulating sleeve 73 on the lateral surface of one end, the centre position of regulating sleeve inwall is wholely set inwardly protruded stripper loop 731, thus regulating sleeve is separated into upper and lower two parts.The upper inside wall of regulating sleeve and lower inner wall arrange left-handed internal thread and the internal thread of dextrorotation respectively, the lower end of upper stay tube arranges left-handed external thread, and being threaded in the top of regulating sleeve, the upper end of lower stay tube arranges the external thread of dextrorotation, and is threaded in the bottom of regulating sleeve.Like this, when we hold upper and lower stay tube and rotate regulating sleeve, upper and lower stay tube can be made close to each other or separately, thus the length of adjustment support bar.Certainly, we also can be fixedly connected with a guide pole 74 in the lower end of upper stay tube up and down stay tube docking, the lower end of this guide pole to be stretched into downwards in lower stay tube and is formed with lower stay tube and is slidably connected, anti-rotation groove 721 from upper opening one end vertically to downward-extension is set at the inwall of lower stay tube simultaneously, and the lower end sidewall of guide pole being arranged position-limitting pin 741, position-limitting pin screens is in anti-rotation groove.Thus make lower stay tube can moving axially along guide pole, and then make can relatively move axially between upper and lower stay tube.When we need the length adjusting support bar, only need hold tight lower stay tube with one, rotate regulating sleeve with another hand simultaneously, now namely regulating sleeve can move up and down along lower supporting rod, meanwhile, upper strut also synchronously moves axially under the effect of regulating sleeve, to adjust the length of support bar, and then is convenient to the adjustment of support bar length.
During use, for the ease of reading and calculating, we are when carrying out accurate adjustment program, first can adjust the length of two support bars in front and back, thus change the height of the first-class senior executive of adjustable stem, make the liquid level shown by indicator dog in former and later two senior executives such as grade identical, and then be convenient to calculating first difference and the second difference, that is, we only need finely tune micro-spiral that inclines, make the calibrated scale on former and later two senior executives such as grade of reading in telescope identical, accurate adjustment program can be completed, make telescopical collimation axis have the higher depth of parallelism.
