Embodiment
Overhanging sensor stand is all generally folding, is beneficial to transport or storage.This overhanging sensor stand has two states usually, and one is folded state, and another kind is then overhanging state, and overhanging direction mentioned in the present invention, refer to the overhanging direction under overhanging state, those skilled in the art can understand.
Overhang, as described in the background section, usual one end is arranged on body by bearing pin, forms a swing arm, then forms controlled deployed condition by some constraint, and overhang state in other words.
Force analysis: for overhang, when the hitch point of such as cable wire 1 is higher than the centre position of overhang at vertical direction, and the other end of cable wire 1 also higher than this centre position time, draw cable wire 1, then the one end that overhang can be made to overhang is subject to a power upwards.
Hydrous water level, stretches the horizontality of drawing and making level meter be in instruction by cable wire.
Routinely, known overhanging sensor stand is generally that its overhanging part is assemblied on body by the bearing pin that is vertically arranged, and have around the degree of freedom of this bearing pin at horizontal rotation in surface, and form foldable structure, the folded state of foldable structure and the angle of deployed condition are 90 degree, usually be symmetrically provided with storage area at body, middle part is protruding, thus utilizes projection to carry out the spacing of folded state.
During deployed condition, usually by a such as baffle plate, carry out 90 degree spacing, form seat portion by this, structure is very simple.
With this understanding, bearing pin bottom is by bearing or be directly fixed on body, forms the overhanging structure of another kind of meaning.
One end of overhang, the frame linking end namely often said, have vertical axis hole 2, thus can be assemblied on bearing pin, no matter according to the mounting means of bearing pin, and form the assembling mode that such as axis hole 2 is fixedly connected with or the assembling mode be rotationally connected, be use which kind of mode, a flexible connection will inevitably be there is, and form fit-up gap.
The rod member overhang can amplify this fit-up gap, in other words, along with the growth of rod member, according to similar triangle theory, overhang longer, the sag of chain of projecting end is larger, and deadweight is larger, larger to the enlarge-effect in gap, be not only the deflection deformation produced of conducting oneself with dignity, be also that the distortion in fit engagement face is mated sagging.
Form the bad composition surface in mechanical field due to this mode, the turning torque on composition surface axis hole 2 being caused to coordinate with bearing pin due to overhang in other words, thus form composition surface discontinuity during normal use, also therefore easily lost efficacy.
For clearly expressing the structure of overhanging sensor stand, Figure of description 1-8 have employed the blast technique of painting, simultaneously by main two parts, namely seat portion and overhang are separately drawn, and eliminate this parts be easily readily appreciated by one skilled in the art of such as bearing pin.
Also two parts are mainly comprised based on radix scrophulariae sensor stand of the present invention, namely portion's (see accompanying drawing 5 ~ 8) and one end are contained in the overhang for linear array transducer (see accompanying drawing 1-4) in described seat portion by a vertical bearing pin, overhang will be horizontally disposed with, thus makes the sensor of linear array be positioned at same surface level.
Be exactly bearing pin and the coordinating of axis hole 2 so as to what ensure, the bearing pin vertically arranged is vertical with overhang, and one side bearing pin is fixedly connected with overhang, form L-type structure, bearing pin and body form revolute pair, are formed and coordinate, and produce tolerance clearance owing to there is flexible connection.
Another kind is that bearing pin is fixedly installed, vertical being fixed on body of bearing pin in other words, and adopts revolute pair to be connected between bearing pin with overhang, also can there is a flexible connection, and produce tolerance clearance.
When overhang is launched, other positions of overhang have lacked support, and overhang is overhanging, and that mainly relies on bearing pin vertically controls oneself the horizontality ensureing overhang, tolerance clearance can cause the deflection of engage over glaze line, thus creates the sagging of overhang projecting end.
Make this overhang have the degree of freedom of rotating around bearing pin axis by bearing pin with coordinating of seat portion, thus can be unfolded or fold.
For overcoming the harmful effect of tolerance clearance to overhang overhanging state, being provided with the first lanyard portion on the top in described seat portion, correspondingly, being provided with the second lanyard portion on the top of the overhang other end.Two lanyard portions with the use of, relatively-stationary seat portion, little on the impact of lanyard, in some applications, perhaps the first lanyard portion and bearing pin decentraction, causes the first lanyard portion and the second lanyard portion spacing in rotation process to change.
With this understanding, can further relate to, such as allow the first lanyard portion and bearing pin, Fig. 1 central axis hole 2 with one heart (also can be called coaxial cable), would not produce the problem that the first lanyard portion and the second lanyard portion spacing change in rotation process so in other words.
In the structure such as shown in Fig. 5, the hanging cable post 18 in figure can be arranged on directly over axle bed hole 22, does not affect the assembling of bearing pin, and can ensure with one heart.
Such as, and for the situation of such as hanging cable post 18 with axle bed hole 22 decentraction, the structure shown in Fig. 5, can be resolved further in the scheme in lower.
First general situation is seen, we claim such as the first lanyard portion and the bearing pin situation that axis hole 2 is concentric in other words, need not consider with this understanding the problem that the first lanyard portion and the second lanyard portion spacing change directly can be configured with the cable wire 1 in a connection first lanyard portion and the second lanyard portion.
With this understanding, for adapting to different application, such as ambient air temperature change, tolerance clearance can change, cable wire 1 can not be made to be in fixing length, and therefore, one of the first lanyard portion and the second lanyard portion are the movable lanyard portion that position is adjustable on both line directions.
When such as hanging cable portion 18 and the situation of axle bed hole 22 decentraction, can arrange an elastomeric element, such as spring, this spring is connected between cable wire 1 and the first lanyard portion or the second lanyard portion, can produce certain nargin.
Preferred structure is the first lanyard portion situation concentric with axis hole 2.
Second case, namely there is the structure of such as spring, have the use that it is original in some applications, the angle such as launched is different, the length that spring is opened can be different, situation such as shown in Fig. 5, when folded state, spring must be in minimum amount of tension, and when deployed condition, spring must be in maximum amount of tension, belongs to a kind of regulative mode of self-equilibrating, and reduces the conciliation frequency in the second lanyard portion.
In second case, the line of centres in hanging cable post 18 and axle bed hole 22 is consistent with overhanging direction.
For the benefit of adjust, and be provided with level meter at the upper surface of overhang.
Level meter is the low-angle conventional measurer of a kind of measurement.In machinery industry and instrument manufacture, for measuring the horizontal level installed relative to the pitch angle of horizontal level, the flatness of lathe kind equipment guide rail and linearity, equipment and upright position etc.
Can be divided into by the profile difference of level meter: Universal level-metre, cylinder level meter, integrated water level, mini level meter, camera level meter, frame level, chi formula level meter; Can be divided into again by the fixed form of level: adjustable water level and can not mode level meter.
Can adopt the simplest level meter in this programme, namely spirit level, it has the cavity volume of a column, accommodates water in cavity volume, and there is a bubble the inside, for detection faces whether level.
After overhang is launched, just can find out overhang whether level intuitively by level meter, if out-of-level, the distance between adjustment first lanyard portion and the second lanyard portion can be passed through, thus tractive projecting end, make it increase, for leveling.
Even if should be appreciated that to there is elastomeric element, the leveling of overhang also can not be affected.Can, according to the further leveling of the degree of tightness of elastomeric element, such as, because elastomeric element is excessively stretched, cause overhang to upwarp, projecting end be higher than other parts of overhang in other words, can turn the distance between the first lanyard portion and the second lanyard portion down, bring out the best in each other.
About described seat portion, conventional seat portion can be adopted, only there is restraining structure, namely retrain out the freedom of movement of overhang 90 degree.
But have in actual use in the face of such problem; user is when using these equipment; operation can not be gone according to code; such as; because the overhang launched is to people's one sensation; overhang can be lifted; therefore; in actual applications; the overhanging sensor stand possessing this structure often can by people as handle, thus cause bearing pin part will carry the whole weight of body, can damage the mating surface of bearing pin on the one hand; on the other hand, the damage of bearing pin or mating surface may directly be caused.
Therefore, see Figure of description 5-8, in some preferred embodiments, described seat portion comprises:
Backboard 19, is vertically arranged, and is configured to one piece of riser, as shown in Figure 5, vertical with the overhanging direction of overhang, during folded state, forms folding constrained.
Configure a location-plate 23, vertically arrange, with described backboard 19 vertical connection and form right angle restraining structure, form the about beam angle of 90 degree on the whole, the expansion and the folded state that retrain overhang are spacing.
And the downside coplanar of the downside of location-plate 23 and backboard 19, as shown in Figure 5, and form the joint face be connected with body.
And then configuration top board 24, this top board 24 is flatly engaged on backboard 19 and location-plate 23, the lower surface of this top board 24 and the distance of joint face are that overhang is connected with seat portion partly at the thickness of vertical direction, and this top board 24 is provided with the axis hole 2 for installing vertical bearing pin one end.
In such an embodiment, the existence of top board 24 can form supporting role more reliably on the one hand, and can ensure the relative level state of overhang, horizontal adjustment afterwards is just turned into fine setting.
On the other hand, composition surface increases, when overhang is lifted as handle, the lower surface of top board 24 forms a pressure-bearing surface, and extrude the second pressure-bearing surface 14 as shown in Figure 1, make the lower surface also pressure-bearing of overhang frame linking end, force part is no longer simple bearing pin and mating surface thereof, and further comprises each pressure-bearing surface, thus effectively can avoid the damage of bearing pin and mating surface thereof.
According to the overhang that said structure is formed, can handle be configured in theory, meanwhile, also should reduce the summary that it uses as handle as much as possible, can not at will it be used as handle by working specification constraint.
The for the benefit of smooth expansion of overhang, the side of described top board 24 location-plate 23 is dorsad provided with the guiding face 26 rotating incision for overhang.
Should be appreciated that the frame linking end of overhang is always positioned at a portion due in the folded state of overhang, deployed condition and expansion process, itself do not need overall importing, therefore, the such as selection of guiding face 26 is that the one of preferred embodiment is selected.
In addition, in some applications, leader also can be arranged on the frame linking end of overhang.
In better embodiment, as Fig. 1-4, described seat cage structure is double-decker, for described top board 24 separates between two parties, the structure being wherein positioned at upper strata contains one and is parallel to and on overhanging direction, is longer than the top board of top board 24, top board and the side coplanar of top board 24 in side, overhanging direction, and be configured to inclined-plane;
Correspondingly, described overhang is formed with the inclined-plane coordinated with face, face, described inclined-plane.
The position that this structure is conducive to cable wire 1 is selected, such as, cable wire can be specially arranged in the superstructure of double-layer structure, thus can obtain by cable wire 1 power that projecting end is raised up.
On the other hand, the said structure of transversal section complexity, shearing resistance section factor is very large, overhang, and the shear resistance comprising a portion is higher, and stiffness by itself is high, and self-deformation is little on result of use impact.
In addition, the overhang that rigidity is larger and seat portion are out of shape by as being also less likely to occur during handle in overhang, ensure that its relative safety used.
Inclined-plane coordinates the front pressure-bearing surface of formation, reduces the ratio of bearing pin pressure-bearing, thus reduces the possibility of core component damage.
In certain embodiments, described overhang is also configured to double-decker, wherein the parts of understructure to be xsect be rectangle frame, and form support portion, superstructure is used for the cabling of sensor and passing of cable wire 1.
Comparatively speaking, the cable of sensor needs to be fixedly installed to a certain extent, therefore, can reserve space passing through for cable wire 1.
In certain embodiments, in the superstructure of overhang, be provided with binding post 4, for the connection of the fixing of sensor cable with sensor.The position of binding post 4 can by specific settings, thus avoids the impact of passing cable wire 1, and binding post 4 can possess certain height.
In preferred embodiment, be provided with between this two binding posts 4, two binding post 4 and leave space, for passing of cable wire 1, further reduce the impact of cable routing on cable wire 1.
In certain embodiments, leave cabling space between the side plate 11 of binding post 4 and adjacent overhang, the space between two binding posts 4 is specifically designed to the passage of cable wire 1.
Transversal section is little usually to should be appreciated that binding post 4, often only needs the assembly space of one or two screws.In addition, little due to the linear array density of sensor, therefore, the xsect of binding post can than large in the direction of the width on the length direction of overhang, thus reserving of cabling space is feasible.
Further, to conduct oneself with dignity the impact produced to reduce cable wire 1 self, especially himself possessing must be flexible, easily trembles, and affects sampling precision, for this reason, in the superstructure of overhang, can arrange a pipeline, for passing of cable wire 1.
Some supporting constructions can also be set, for cable wire being supported in a rational plane.
As shown in Figure 1, demonstrating cable wire approaching channel 3 in figure, is a U-type groove or semi-circular groove, for supporting cable wire.For avoiding lines to disturb in figure, the mode that cable wire 3 is drawn for running through the first pressure-bearing surface 12, but does not affect the understanding of those skilled in the art.
About the first pressure-bearing surface 12, be configured in the frame linking end of superstructure, form the pressure-bearing surface that area is relatively large.
The upper plate 5 that the superstructure of overhang is contained biside plate 11 and fastened by monolateral button with the top of biside plate 11, this upper plate 5 array has the bore 6 of installing for sensor, and monolateral buckle structure is very simple, and facilitates the dismounting of fastening structure, therefore, the installation and maintenance of sensor is beneficial to.
Described movable lanyard cage structure is the screw that a circumferential restrained axis has self-locking thread freely, and one with the screw mandrel 7 of handwheel 8 and this screw threaded engagement;
Wherein, screw is connected with cable wire 1, and the axis of screw mandrel 7 is the direction that two lanyard portions are connected by cable wire 1.
The lead angle of self-locking thread is smaller, namely to rotate the drive volume of the such as screw that a circle produces relatively little for handwheel 8, produces so-called spiral fine tuning structure, therefore, in order to obtain accurate adjustment, lead angle can be adopted to be less than the self-locking thread of 15 degree.
In addition, about the connection of seat portion and body, screw can be adopted to connect, and such as on face of weld 20 as shown in Figure 5, face of weld 21, form screw hole, corresponding aperture on body, carry out screw connection, this structure easily ensures assembly precision.
In certain embodiments, directly can adopt welding, the strength of joint of welding is very high, but easily causes the distortion of face of weld 20, face of weld 21, and affects assembly precision, and non-disconnectable, later maintenance inconvenience.
