Description

A kind of total powerstation

Technical field

This utility model relates to a kind of engineering survey apparatus field, particularly to a kind of total powerstation.

Background technology

Along with the development of society, the progress of science and technology, needing to use total powerstation in Surveying and Mapping Industry, total powerstation is when in use Can carry out the regulation of differing heights according to different places and condition, total powerstation is that mapping provides convenient science bar Part, the leg of total powerstation can allow instrument be in steady statue so that during operating instrument, to deviateing on time when not havinging Situation.Enable instrument to be accurately erected at directly over control point or survey station point or underface, namely ensure instrument water The center of circle of Pingdu dish is motionless on the plumb line at control point or survey station point place.Participate in instrument leveling and centering process, by stretching Contracting frame lower limb so that instrumental correction is accurate；But can not realize the accurate regulation to total powerstation by the regulation of expansion bracket lower limb, it is right to need Further accurate calibration is carried out, to ensure the accuracy that total powerstation is tested, thus between triangular base and the base plate of total powerstation Problem derives this programme.

Utility model content

The purpose of this utility model is to provide a kind of total powerstation that can realize accurate calibration.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of total powerstation, including Triangular base and be positioned at the base plate immediately below triangular base, described base plate is provided with central authorities towards the one side of triangular base and prolongs Stretching and the chute of downward-sloping setting, described chute is circumferentially provided with three described chutes, institute around the centre of base plate Stating the bottom of chute and be provided with tooth bar along the glide direction of chute, on described triangular base, sliding connects the gear having pinion rack, Passing base plate on described gear and be provided with the handle driving gear to move back and forth on tooth bar, described base plate is provided with determining of location gear Position part.

By using technique scheme, handle strip moving gear realizes rotating, real by the way of wheel and rack engages Existing gear movement on tooth bar；The gear of movement, under the effect of chute bottom angled, makes gear produce during running Raw difference in height, and by the way of gear is connected with triangular base sliding, makes the movement of gear can't affect triangular base and exist Movement in horizontal direction, thus realize triangular base regulation in height；By the way of engagement, there is higher biography Dynamic ratio and transmission accuracy, it is achieved the accurate regulation effect to total powerstation.

This utility model is further arranged to: on described triangular base, sliding connection adapts to chute and slides towards chute Moving the slide block that direction is arranged, described gear is arranged on slide block.

By using technique scheme, slide block is adaptive with chute, makes chute can play slide block along glide direction both sides Chucking power, make the rolling power that triangular base will not be produced on other directions by the slidable adjustment of slide block, promote the accurate of regulation Degree；And by the distance arranged between minimizing slide block and chute of slide block, make the particulate matter in extraneous air be not easily accessed In chute, the resistance produced when reducing gear pinion rack, promote the degree of regulation of total powerstation.

This utility model is further arranged to: described chute is near the sidewall of one end of sidewall of the bottom plate connection base plate.

By using technique scheme, the sidewall of chute connection base plate, the one end making chute is opening, reduces chute Sidewall barrier force that chute inside is produced；Make the particulate matter mass-energy dropping in chute convenient clear out of chute, Reduce the barrier force that gear is subject in rotation process, promote the degree of regulation of total powerstation.

This utility model is further arranged to: described keeper include through base plate and with gear away from handle threaded one end The bolt connected.

By using technique scheme, bolt is threadeded with gear and under the drive of helix shape characteristic, makes Bolt towards gear a side shifting and make bolt head conflict on the outer surface of base plate, it is achieved the location to gear.

This utility model is further arranged to: described keeper includes the magnetic piece being set on handle for adsorbing base plate.

By using technique scheme, the magnetic piece being set on handle realizes moving axially on handle, works as needs When the gear connected on handle is fixed, by magnetic piece towards the side shifting at base plate place, the magnetic produced by magnetic piece Handle is fixed on base plate by absorption affinity, it is achieved the position-limiting action to gear.

This utility model is further arranged to: described gear is arranged on the slide block side near triangular base centre.

By using technique scheme, gear is arranged on the slide block side near triangular base, makes wheel and rack Between remain with the longest engagement rotation path, increase the height of gear adjusting triangle pedestal, promote the regulation model of triangular base Enclose, by the way of this kind of setting, promote the practicality of total powerstation.

This utility model is further arranged to: be arranged with movable sleeve on described handle and restraint set axially moves along handle Dynamic.

By using technique scheme, movable sleeve band fixed handle on hand gripping handle realize circumferentially rotating, logical Cross arranging of movable sleeve to reduce the change of handle motion direction and hand causes unnecessary frictional resistance, make hand energy more preferably Grip movable sleeve to movable sleeve apply rotate driving force, lifting force stationarity in transmitting, promote total powerstation tune Joint precision.

This utility model is further arranged to: described slide block is provided with buffer substrate tablet towards the end face of triangular base centre.

By using technique scheme, when keeper does not apply fixing active force to gear, strength of gear triangle Under the effect that the gravity of pedestal and chute are obliquely installed, slide block can be made to move towards the side that chute height is relatively low；Make sliding Block impinges upon on the sidewall of chute, the counteracting force produced by chute wall, transfers force on gear, affects the knot of gear Structure precision；Play the effect of buffering by the slide block to landing that arranges of buffer substrate tablet, slow down the counteracting force of generation, promote gear Structure precision, increase regulation accuracy.

This utility model is further arranged to: be connected by T-slot sliding between described slide block and triangular base.

By using technique scheme, T-slot has good sliding, can well realize slide block at triangular base On slip, and the setting of T-slot adds the contact area between slide block and triangular base, and the sliding making slide block is more steady Fixed；T-slot has good chucking power along the both sides of slide block glide direction, promotes the stability that slide block runs.

In sum, what this utility model had the advantages that gear rotates through the mode band engaged with tooth bar Moving gear moves on tooth bar, and under the effect that chute is obliquely installed change gear movement time difference in height, to triangular base Play the regulation effect of height, it is achieved the accurate regulation to total powerstation.
