Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is general structure schematic diagram of the present invention, and Fig. 2 is the drive mechanism schematic diagram (amplification) of screw mandrel in Fig. 1, handwheel, transmission platform composition, and Fig. 3 is the structural representation of standard stadimeter erecting frame.
As shown in FIG. 1 to 3, a kind of reflective level meter calibrating operator's console, comprise operation stand 12, transmission flat board 7, instrument mounting bracket 4 and standard stadimeter erecting frame 11, it is characterized in that: the supporting 1 being equipped with horizon adjustable below described operation stand 12, the operation left and right sides, stand 12 top is provided with guide rail 14 parallel each other, transmission flat board about 7 two ends are connected with described guide rail 14 by guide-rail coupling member 10, be fixedly connected with the screw mandrel 6 being placed in described operation stand 12 top in the middle of described transmission dull and stereotyped 7, handwheel agitation member 9 is equipped with in described screw mandrel 6 one end, handwheel agitation member 9 is equipped with index dial 8, when rotating handwheel, described screw mandrel 6 can drive described transmission flat board 7 to move forward and backward along described guide rail 14,
Dull and stereotyped 7 upper surfaces are vertical is fixedly connected with for described instrument mounting bracket 4 and described transmission, instrument mounting bracket 4 are equipped with flange 5;
Described standard stadimeter erecting frame 4 lower surface connects with dull and stereotyped 7 upper surfaces of described transmission, the relevant position that dull and stereotyped 7 left and right sides of the left and right sides of described standard stadimeter erecting frame 4 and described transmission are symmetrical each other, be equipped with the pilot hole 16/16 ' of multiple longitudinal arrangement respectively, standard stadimeter erecting frame 4 is fixedly connected with transmission flat board 7 by the register pin being placed in described pilot hole 16/16 ';
Two standard stadimeters 15 are parallel and be symmetrically placed in the two ends, left and right of described standard stadimeter erecting frame 4, and the distance between two standard stadimeters 15 is greater than the width of described transmission flat board 4.
Described guide rail 14 is marked with grade length scales.
Described operation stand is underlying 4 Moving casters 2.
The supporting 1 of described horizon adjustable has 4.
Operation stand 12 of the present invention has the supporting 1 of 4 adjusting water Pingdus, the levelness of horizontal for adjustment operation table top 13, vertical both direction, matching standard surveyor's staff, by regulating the height of supporting 1, can ensure operating table surface 13 maintenance level in both directions all the time.4 Moving casters 2 are except playing fixation, and also can facilitate the movement of whole operator's console, such design avoids the limitation of the fixed installation of operator's console, use flexibly and can reduce to take up room, and meet the requirement that clearance-type uses.
When the present invention uses, when operating personnel shake handwheel agitation member 9, screw mandrel 6 can be driven to move, because the display of handwheel agitation member 9 rotational angle is easier to observe than the displacement of screw mandrel 6, so can realize the control to the movement of screw mandrel 6 grade like a cork by the rotation amplitude controlling handwheel agitation member 9, the method can act on the resolution of instrument and the calibrating of return difference easily.In addition, by the total displacement of length more than 1m, can be used for the calibrating of the instrument linearity.Meanwhile, because transmission flat board 7 and screw mandrel 6 link, so the movement of screw mandrel 6 causes transmission dull and stereotyped 7 and its synchronization action.Instrument mounting bracket 4 is vertically fixedly installed on transmission flat board 7, instrument mounting plane and transmission dull and stereotyped 7 is made to keep 90 ° of vertical relations, instrument 3 is installed on flange 5, Flange Plane is combined with the vertical plane of instrument mounting bracket 4, instrument 3 installation direction and surface level keeping parallelism can be made, therefore the mobile instrument 3 that drives of transmission flat board 7 moves in the horizontal direction, thus adjustment instrument receives the distance of reflection wave.And be connected by flange 5 with instrument mounting bracket 4 due to instrument 3, by changing the aperture of flange 5, the calibrating of different size instrument can be realized easily, make ultrasound wave instrument and radar instrument can share same operator's console.By register pin is inserted in pilot hole 16/16 ', standard stadimeter erecting frame 11 can be fixedly installed on the transmission flat board 7 of operation stand, and 7 interlocks dull and stereotyped with transmission, because the pilot hole 16/16 ' being symmetrically arranged with multiple longitudinal arrangement corresponding on transmission dull and stereotyped 7 and standard stadimeter erecting frame 11, therefore by the relative position between adjustment pilot hole 16/16 ', the spacing of adjustable standard stadimeter erecting frame 11 and instrument mounting bracket 4 vertical plane, the consistance of reference field thus adjustment stadimeter reference field and instrument are found range, be applicable to examine and determine the instrument of difference range finding benchmark.Be placed on the two ends of standard stadimeter mounting bracket 11, except using one of standard stadimeter 15 as except standard basis, also can checking the installation quality of reflecting plate (comprising levelness and verticality) standard stadimeter 15 Parallel Symmetric.
Above to the description of embodiment, be intended to further illustrate the technical scheme that the present invention relates to, those of ordinary skill in the art understood and applied the invention, is not intended to limit the invention.Should be appreciated that every based on the present invention's enlightenment, any apparent conversion or equivalent alternative, also should be considered to fall into protection scope of the present invention.
