Detailed description of the invention
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in Fig. 2, a kind of level gauge quick level-off structure, including pedestal 2, the level gauge body 2 of pedestal upper surface it is rotatably connected on by the vertical axes being perpendicular to pedestal upper surface, and it is arranged on the connecting bottom board 3 of pedestal bottom, this internal telescope being provided for measuring of level gauge, level gauge rear body horizontally set one is for monitoring the circular bubble 41 of initial adjustment programmed level degree, circular bubble is perpendicular to telescopical collimation axis, also need on level gauge body to arrange a micro-spiral 5 that inclines for accurate adjustment, one pipe spirit level 42 parallel with telescopical collimation axis is set at level gauge body one side simultaneously, with depth of parallelism during monitoring accurate adjustment program.In order to complete just to debug 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, and the upper and lower surface of the through connecting bottom board in both sides up and down of this spherical hollow space, so that spherical hollow space is cydariform small in the end and big in the middle.One discoid rocker piece 32 is set in spherical hollow space, the sphere that the lateral surface of rocker piece is and spherical hollow space is adaptive so that rocker piece can in spherical hollow space 360 degree of all-direction rotations.Centrally disposed the one of rocker piece is 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 from bottom to up after the connection circular hole of rocker piece, swing arm arranges the stop nut 35 of the rocker piece that reclines being positioned at rocker piece upper position, swing arm arranges the spacing ring 331 of the rocker piece that reclines being positioned at rocker piece lower position, so that rocker piece is at the axial upper limit of swing arm.It is to say, the weight of level gauge body now and pedestal all passes to rocker piece by swing arm, and it is in a kind of quick condition.It 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 regulation screw 36, it is preferable that the quantity of regulation screw is four.When we unscrew regulation screw, the upper end of regulation screw can be resisted against on the lower surface of pedestal.Lower surface at connecting bottom board arranges three telescoping support feet 9 around spherical hollow space, so that swing arm is positioned at the centre of telescoping support foot.
During measurement, after we have set up telescoping support foot, we need first to be screwed in connecting bottom board regulation screw, to make it be separated with pedestal, so, pedestal and level gauge body i.e. can be at quick condition, and now swing arm can swing back and forth under the action of gravity of correction weight, finally it is automatically adjusted to plumb line position, so that level gauge ontology alignment is to level.So we only need the regulation screw of turn the most successively, make the upper end lower surface against pedestal of regulation screw, the position of level gauge 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 just debugged.Then accurate adjustment program can be carried out by micro-spiral that inclines, till the bubble of pipe spirit 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 level gauge body as an overall center of gravity, and the lower surface that telescopical collimation axis is arranged to pedestal is paralleled, so can ensure that in a free state, swing arm can be automatically adjusted to plumb line position, will not produce slight inclination because of the bias of level gauge body gravity.It addition, we also can arrange latticed lubrication groove outside rocker piece on sphere, in lubrication groove, it is coated with lubricant grease, to reduce frictional force when rocker piece rotates in spherical hollow space, it is ensured that swing arm can be adjusted to plumb line position completely simultaneously.And regulate screw and expose the upper end of connecting bottom board and can be set to bulb, and hexagonal rotation section is set at the spiro rod section of regulation screw, in order to it is rotated by instruments such as spanners.
Installation for the ease of rocker piece, 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 inserting groove are positioned at the diametric(al) of spherical hollow space, the medial surface inserting groove is connected with spherical hollow space and forms opening shape, the lateral surface 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 inserting groove should be greater than the thickness of rocker piece.So, when we need to install, can first make discoid rocker piece perpendicular with base-plates surface, now rocker piece can be put into two and insert in groove；When rocker piece to insert in groove move to bottom time, sphere outside rocker piece fits with the sphere of spherical hollow space, and the centre of sphere of two spheres overlaps, and rocker piece is rotated 90 degree by again, making it parallel with pedestal, rocker piece now can be spacing in spherical hollow space；Then we again by swing arm from bottom to up through the connection circular hole on rocker piece, and make the spacing ring of swing arm recline rocker piece, then screw on stop nut in the upper end at swing arm, can make swing arm axial limiting on rocker piece；Finally again swing arm is threaded on the lower surface of pedestal.
It should be noted that, we can be connected one end first threaded back nut on swing arm with pedestal, this back nut is the most integrally connected and composed by hexagonal locking end and discoidal supported end, so, after swing arm is connected with base thread, we can lock back nut by hexagonal locking end, make the circular end face of its supported end tightly against the lower surface of pedestal, so, on the one hand the self-locking of swing arm can be realized, it is avoided to loosen voluntarily, be conducive to the perpendicularity improving swing arm with pedestal lower surface simultaneously, avoid reducing the precision just debugged because of the deflection of swing arm.
In order to improve the precision just debugged further, we also can laterally be horizontally disposed with a counterweight screw rod 332, and a threaded balancing weight 333 respectively in the left and right sides of counterweight screw rod at correction weight in the bottom of swing arm.So, we are when carrying out just debugging, if circular bubble display level gauge body is not the most completely in level when swing arm stops swinging, can be by rotating the balancing weight of counterweight screw rod both sides, make it away from or near swing arm, thus produce an additional correction moment, make swing arm swing a small angle in the lateral direction together with pedestal i.e. level gauge body instrument, until the bubble middle position of circular bubble, i.e. complete initial adjustment correction to program work.It is understandable that, counterweight screw rod should be symmetrical arranged in the left and right sides of swing arm, and at balancing weight side, one latch segment being threaded on counterweight screw rod can additional be set, after balancing weight position determines, latch segment is tightened and is close on balancing weight, so that the position of balancing weight is fixed, in order to the accuracy debugged at the beginning of when guaranteeing again to measure.
In order to improve the precision of accurate adjustment program, we also can be respectively provided with the axially extended telescopic distance rod 6 along telescopical collimation axis in the forward and backward side of pedestal, and the telescopic distance rod of the forward and backward side of pedestal is coaxially arranged.Specifically, telescopic distance rod includes some telescopic tubes 61 connected together from the inside to the outside, the cross section of telescopic tube is rectangular, and to avoid producing relative rotation between each telescopic tube, in telescopic distance rod, the tail end of outmost telescopic tube is connected on pedestal.In addition, as shown in Figure 5, laterally arranging the positioning strip 63 with the axis perpendicular of telescopic tube on the tail end medial wall of each telescopic tube, wear a spacing steel wire 64 in telescopic distance rod, spacing steel wire is connected with the positioning strip on each telescopic tube of telescopic distance rod successively.Thus the displacement between adjacent two telescopic tubes can be limited, and finally control the length of telescopic distance rod exactly.When we need storage, the telescopic tube of telescopic distance rod can overlapped be socketed, and now, flexible spacing steel wire can correspondingly bend contraction；And when needing to measure, then telescopic tube can be pulled out successively, and accurately define length by spacing steel wire.In addition, it would be desirable in telescopic distance rod, the upside of innermost telescopic tube front end arranges a connecting insertion 62, an adjustable stem 8 is plugged on vertically in the connecting insertion of upside simultaneously.Adjustable stem is flat rod, adjustable stem arranges vertical groove in the middle of the sidewall of level gauge body, transparent senior executive 81 such as grade it is embedded in groove, waiting on two telescopic distance rods is connected by plastic flexible pipe bottom senior executive, Deng filling red liquid in senior executive, wait and the correction scale that can show liquid level is set on the pipe shaft of senior executive.
The telescopic distance rod of the present invention is connected with pedestal by connected structure, in order to dismounting.Specifically, as shown in Figure 6, we can be respectively provided with a circular sleeve 11 in the forward and backward side of pedestal, and the axis of sleeve is paralleled with collimation axis, and the sidewall of sleeve is symmetrically arranged two slots 111, slot is inwardly in the axial direction from the edge of opening of sleeve, the inner bending of slot extends and forms locking slot 112, so that slot and locking slot are substantially L-shaped, locking slot is towards pedestal lopsidedness, thus between locking slot and slot, forming the angle of 92 degree to 95, its optimized angle is 93 degree.Correspondingly, it is connected one end at telescopic distance rod with pedestal and one connection-peg fitted in sleeve 65 is set, the end of connection-peg is the sphere of evagination, and be resisted against on the bottom surface of sleeve, then being symmetrically arranged the elastic clipping strip 651 of two radial directions on the sidewall of connection-peg, elastic clipping strip screens respectively is in two locking slots of sleeve.During installation, we can be by the connection-peg elder generation alignment sleeve retainer of telescopic distance rod, two elastic clipping strips on connection-peg are then respectively aligned to two slots of sleeve, then connection-peg can be made to be inwardly inserted in sleeve, making the bottom surface against sleeve, the end of connection-peg, elastic clipping strip now then reaches exactly to slot root and locking slot junction.Then rotating telescopic distance rod and correspondingly drive connection-peg to rotate, so, the elastic clipping strip of connection-peg sidewall i.e. enters the locking slot of inclination until moving to the inner of locking slot.Owing to having an angle more than 90 degree between locking slot and slot, therefore, locking slot can produce an inside active force to elastic clipping strip, elastic clipping strip is made to produce deformation, the end making connection-peg is resisted against on the bottom surface of sleeve tightly, thus can effectively eliminate the connection fit clearance between telescopic distance rod and pedestal, improve precision, the self-locking on pedestal of the telescopic distance rod can be realized simultaneously, it is avoided to rotate voluntarily, and the end face of connection-peg is sphere, thus it is conducive to rotate.
The present invention in use, debug by the first of collimation axis levelness that can complete level gauge body the most in the manner aforesaid.Then we can be at the front and rear sides of the pedestal telescopic distance rod of grafting respectively, then, telescope is sighted the senior executive such as grade on the adjustable stem of front side, and reading corrects scale value accordingly, this correction scale value is compared with the correction scale value shown by liquid level in such senior executive, i.e. can get the first difference of collimation axis and the contour intraluminal fluid face height of front side；Then level gauge body is rotated 180 degree, telescope is made to sight the senior executive such as grade on the adjustable stem on rear side of pedestal, and reading corrects scale value accordingly, this correction scale value is compared with the correction scale value shown by the contour intraluminal fluid face of rear side, i.e. can get the second difference of collimation axis and the contour intraluminal fluid face height of rear side.Owing to front and back waiting liquid in senior executive to be connection, therefore its liquid level is completely the same, when collimation axis is in level, above-mentioned first difference and the second difference should be completely the same, otherwise, if it is inconsistent, the most fine-tuning micro-spiral that inclines, observes and records the first difference and the second difference the most again, until first, second difference is identical, accurate adjustment program can be completed, make collimation axis keep level.Certainly, telescopic distance rod front and back preferably can be set to the length of one meter, in order to the calculating of collimation axis parallelism error and adjustment.
For the ease of the liquid level in the senior executives such as observation, as it is shown in fig. 7, we can arrange the instruction block 82 of cylinder on the liquid level waiting senior executive, instruction block can be set to redness, its upper surface is a plane, thus can the most accurately correction scale on the senior executive such as comparison, in order to accurately read liquid level.
It should be noted that the upper end of senior executive such as grade should be opened, consequently facilitating the lifting of liquid in pipe is floated, we are when needs are measured, can be by liquid by the senior executives such as the opening injection of senior executive upper end such as grade.Additionally, after completing the accurate adjustment program of levelness, we should remove the telescopic distance rod of both sides before and after pedestal in time, in order to level gauge starts the measurement needing to measure point.
