Description

Slope measuring horizontal ruler

The utility model relates to a kind of deviational survey degree or the flat instrument of water detection, can use in the assembling and setting of the installation of civil engineering, plant equipment or pipeline and instrument and equipment.

The deviational survey degree instrument that Chinese patent 86206373 Gradient measuring rulers and Chinese patent 88211304 annular tube type Clinometers are provided has following weak point: the spirit bubble that 1) is used to measure is positioned at the circular arc transparent tube, it is slower to steep the speed that moves in the measuring process, so poor sensitivity of measuring, and when measuring such as temperature higher, spirit bubble will dwindle, and reading does not allow readability accurate; 2) they can not be used for the measured body of half quadrant interior (that is in 180 ° to 360 ° scopes) under the space, as the slopes test of the indent or the italic of facing upward; 3) reading of their measurements can not be read " branch " intuitively and can only read " degree "; 4) can not be directly fixing on instrument to the reading of measuring, but can only now read existing record; 5) they can not be used at no available light or in the dark that does not have to throw light on.

The purpose of this utility model provides a kind of convenient reading and can directly read degree of tilt is several years deviational survey degree surveyor's staffs somewhat, make it can be used for various planes on the space omnidirectional or the gradient of pipeline or the detection of levelness, the reading of being surveyed can be fixed on instrument easily, and this instrument carries illuminator, and it can be detected in some dark spaces.

The utility model deviational survey degree surveyor's staff includes a rod support and a rotating disk.Rod support can adopt vertical type, and its centre has the hole that center line is a level, in mode movingly a rotating disk is installed in the hole, and its bottom is a detection faces that energy fits tightly with measured body.

Be used for the flat spirit bubble of deviational survey degree or water detection and be positioned at a transparent tube that is installed in the closed at both ends of rotating disk, this pipe is for linear, be close to it be a cover can provide illumination by small electric bulb, battery, pushbutton switch and be connected the lighting device that copper sheet is formed.Be equipped with one in the surface of revolution of rotating disk and can prevent that it from taking off and making it to obtain the locating device of axial location rotation from rod support.Have meter degree scale and the score scale that to represent the measured body degree of tilt on the same side end face of rod support and rotating disk respectively, also have a measuring datum line on the rotating disk.

Also can have one on the rod support and can hold out against rotating disk stops it on a certain reading trip bolt.

To and contrast accompanying drawing by embodiment below is further described below the utility model deviational survey degree surveyor's staff.Accompanying drawing thes contents are as follows:

Fig. 1 is the front elevation that has the deviational survey degree surveyor's staff of two part sections;

Fig. 2, Fig. 3 are respectively B-B, the A-A cut-open views among Fig. 1.

Can see that the rotating disk of installing in the center pit of rod support 12 is made up of lid 20, box body 3 and interior capping 22 3 parts of band turning handle 20 ' on Fig. 1 and Fig. 2, screw 18 and inner bolt 19 are linked to be an integral body to this three part.The upper space of box body has been installed a linear glass tube 4, and alcoholic solution is housed in the glass tube, and the spirit bubble that is used for measuring has measuring index line at this solution on the glass tube.Can see in the behind of the glass tube 4 of box body upper space that in conjunction with Fig. 3 lighting bulb 12 is arranged again, glass tube is with lightlng hole 15 is arranged between the small electric bulb.Lid has a form 5 that detects usefulness for survey crew at place, glass tube position.The switch 13 of a band button 14 has been installed in the centre of box body, and the switch both sides are equipped with the upright battery 11 of two joints respectively, all have copper sheet to connect between battery, switch and the small electric bulb, have formed a lighting device.

Pearl 16 is bumped in the location that a radial arrangement is housed on the surfaces of revolution of rotating disk, with bump have on the inwall of the corresponding rod support of axial location hole, pearl place one the circle guide-track groove 9, the spring 17 that bumps on the pearl pushes its steel ball in the guide-track groove, half that makes steel ball highly embeds this groove, thereby guarantees that rotating disk can not take off and make rotating disk to rotate at the axial location of rod support hole internal fixation in the rod support hole.The trip bolt 10 at rod support top can stop it to rotate from radially the holding out against rotating disk of rotating disk, so that the reading of measured degree of tilt is fixed up on deviational survey degree surveyor's staff.

Have score scale 7 and meter degree scale 6 on the same side end face in rotating disk and rod support hole respectively.Meter degree scale is arranged in a clockwise direction, is half-turn from 0 ° to 180 °, and half-turn is to turn back to 0 ° clockwise from 180 ° in addition, and per 10 ° is big lattice, and every big lattice can be divided into ten little lattice again, promptly 1 °.The score scale is that the principle design by the vernier caliper reading forms, and it is also arranged in a clockwise direction from 60 ' → 0 ' → 60 ', and this scale is equivalent to 59 °～-59 ° scope of meter degree scale on the rod support in the shared scope in center of turntable angle.In Fig. 1,60 ' above the rotating disk be corresponding to 121 ° of scales on the rod support, 0 ' corresponding to 60 ' below 180 °, rotating disk then corresponding to 121 ° of scales below the rod support, (promptly-121 °).With 0 ' symmetry disk position on have datum line 8.

Extend to both sides along the direction at plane of rotor disc place the rod support bottom, and its total length can be about three times of disk diameter.Have a gap slot 21 on the base plane, the slot cross-section shape can be that triangle also can be that circle lacks shape, so that rod support is adjacent to measured body better in measurement.

Deviational survey degree surveyor's staff is close to measured body with the rod support bottom earlier when measuring, and unclamps trip bolt 10, rotates turning handle 20 ' then, and from the form spirit bubble, rotating disk stops operating when spirit bubble reaches index line on the glass tube 4.As needs fixedly reading then can screw trip bolt.At this moment the rod support meter degree scale mark corresponding to rotating disk datum line 8 just is the inclination number of degrees of measured body; Need have a look the direction of dial rotation when reading to score scale, clockwise rotate in this way, from rotating disk, look for 0 ' → 60 ' the scale so one with the fractional value of the immediate score scale mark of the rod support number of degrees as its gradient.If rotating disk is for rotating counterclockwise, look for 60 ' → 0 ' the scale from rotating disk so one with the fractional value of the most approaching score scale mark of the rod support number of degrees as the measured body degree of tilt.As the measurement environment dark, can press button 14 so switch 13 is opened; Also be to press button 14 when closing lighting circuit.

The utility model deviational survey degree surveyor's staff also can be used for plane or pipeline, and the verification of other device inclined degree, at this moment make meter degree scale and score scale reach calibration value as long as rotate rotating disk, stop operating, tighten trip bolt 10 then, deviational survey degree surveyor's staff is close to measured body sees that spirit bubble in its glass tube 4 is whether on index line.

The utility model slope measuring horizontal ruler has following advantage: 1) spirit bubble of slope measuring can be with dial rotation, and floats under the measuring state all the time. Therefore can be for the mensuration of the measured body gradient in each orientation, space, especially solved and faced upward or the measurement problem of indent italic. 2) highly sensitive, convenient reading and the collimation error are little, also can directly read gradient with " degree " and " branch ". 3) read data can stay on the horizon rule easily. 4) self illumination is easy to use.
