Description

Foot-operated measurement foot rest
Technical field
The utility model relates to a kind of measures auxiliary device, especially a kind of easy to carry, processing ease, effectively can improve the foot-operated measurement foot rest measuring efficiency and stability.
Background technique
In geodetic survey and engineering survey field, need to be placed in above survey mark point by vertically stable for the surveying instruments such as electronic tachometer, level instrument, global positioning system, surveyors' staff (measurement of the level scale, electronic tachometer reflecting prism centering rod, satellite positioning surveys centering rod etc.) to stand upright on survey mark point and keeps steady state just can measure.The measurement foot rest that tradition uses is tripod, namely by planar pedestal (also referred to as frame head, the i.e. device of retainer instrument and scale) and three legs hinged with pedestal form, because surveyors' staff (measurement of the level scale, electronic tachometer reflecting prism centering rod, satellite positioning surveys centering rod etc.) cannot be applied to, therefore need the hand steered operation of survey crew, namely whether survey crew adjusts surveyors' staff between two parties by the bubble observing level indicator, and is in plumbness by the hand steered surveyors' staff that makes.Obviously, traditional method not only wastes time and energy, and is difficult to ensure accurate leveling, thus reduces the validity of measurement.In order to solve the problem, the patent No. is the Chinese invention patent of 201210267959.2, discloses one " sleeve clip type measurement tripod ".The main contributions of " sleeve clip type measurement tripod " is that the pedestal of traditional foot rest is changed to ring-type by planar, and on ring-type pedestal, be evenly equipped with at least three horizontal jackscrews, first for surveyors' staff provides special measurement foot rest, improve the validity that surveyors' staff is uprightly vertical.The patent No. be 201320031853.2 Chinese utility model patent disclose one " Holding-clamp type measurement foot rest ", it is the improvement that " sleeve clip type measurement tripod " is carried out, the leg that its structure has pedestal and connects with pedestal, pedestal is ring-type, described pedestal has opening, pedestal is furnished with two horizontal jackscrews, all there is fixed connection apparatus the front end of each horizontal jackscrew, or be furnished with three horizontal jackscrews on pedestal, there is fixed connection apparatus horizontal jackscrew front end placed in the middle; Mutually vertical between described adjacent transverse jackscrew axis ".But all there is following problem in actual applications in " sleeve clip type measurement tripod " and " Holding-clamp type measurement foot rest ":
1. need three legs and surveyors' staff four fulcrums to be placed in ground, affect by ground factor comparatively large, difficulty is installed, stability is poor;
2. three legs are support force to surveyors' staff, increase the difficulty of jackscrew adjustment surveyors' staff;
3. the angle between three legs is 120 degree, affects the observation to measurement of the level scale;
4. three legs carry and operate equal inconvenience.
The problems referred to above directly reduce measurement efficiency.
Summary of the invention
The utility model is the above-mentioned technical problem in order to solve existing for prior art, provides a kind of easy to carry, processing ease, effectively can improve the foot-operated measurement foot rest measuring efficiency and stability.
Technical solution of the present utility model is: a kind of foot-operated measurement foot rest, there are pedestal and the leg hinged with pedestal, pedestal is ring-type, pedestal is furnished with at least two orthogonal horizontal jackscrews, described leg is 1 ~ 2, is connected to the horizontal foot-driven lever axially vertical with leg in the lower end of described leg.
Described pedestal is built-in with vertical support bar, and height graduation is carved with on vertical support bar surface.
Described leg is 2, and the angle between 2 legs is less than 180 degree.
The utility model tool has the following advantages:
1. maximum two horizontal foot-driven levers and surveyors' staff three fulcrums are placed in ground by a needs, affect less by ground factor, install easy, good stability;
2. surveyor rides horizontal foot-driven lever, utilize the own body weight of surveyor will measure foot rest relative with ground fixing, make the leg of measurement foot rest not only have support force effect, also there is pulling force effect simultaneously, be convenient to the perpendicularity adjusting surveyors' staff, reduce the difficulty of jackscrew adjustment surveyors' staff;
3. the angle between two legs is less than 180 degree, namely two legs can be placed in surveyors' staff below or side, do not affect the observation to measurement of the level scale;
4. two legs carry and more convenient to operate.

Embodiment
Embodiment 1:
As shown in Figure 1, 2: same as the prior art, the pedestal (also known as frame head) 1 having the materials such as metal to make and with pedestal 1 by the hinged leg 2 of link 5, pedestal 1 is the rectangular of opening, pedestal 1 is furnished with at least 2 orthogonal horizontal jackscrews 3, be leg 2 with prior art difference be one, the lower end of leg 2 is connected by two connecting rods 6 and the axially vertical horizontal foot-driven lever 4 of leg 2.
During use adopt spring band 7 by surveyors' staff 20 fixed in position in pedestal 1, to be placed on survey mark point bottom surveyors' staff 20, manually make open and make foot-driven lever 4 be contacted with ground outside leg 2, the survey crew foot-driven lever 4 that tramps with one's feet makes leg 2 and ground fix, adjustment surveyors' staff 20 is substantially vertical, level indicator 8 on recycling surveyors' staff 20 is finely tuned by horizontal jackscrew 3, can accurately make surveyors' staff 20 be in plumbness.
Embodiment 2:
As shown in Figure 3: basic structure, with embodiment 1, with embodiment 1 difference is: the angle be provided with between two legs, 2, two legs 2 is less than 180 degree, every root leg 2 lower end is all connected to the horizontal foot-driven lever 4 axially vertical with leg 2.
The use working procedure of embodiment 2 is substantially with embodiment 1, and difference need slam two respectively with bipod to ride.
Embodiment 3:
As shown in Figure 4: basic structure, with embodiment 2, with embodiment 2 difference is: pedestal 1 is the circle of opening, is built-in with vertical support bar 9 at pedestal 1, height graduation 10 is carved with on described vertical support bar 9 surface.
Use working procedure substantially with embodiment 2, difference is: first by the surveying instrument such as electronic tachometer, level instrument 30 fixed in position in the top of strut 9, re-use by horizontal jackscrew 3 and spring band 7 by strut 9 fixed in position in pedestal 1.
