Background technique
Tripod is securing device conventional in a kind of engineering, has a wide range of applications in measurement technique field.Measuring conventional level instrument, theodolite, electronic tachometer etc. all needs tripod as its supporting part, and the use of these instruments all needs leveling, and this just requires the tripod susceptor surface level of supporting part.When existing tripod uses, first by tripod base middle part fixing bolt, instrument is fixed on base, carries out artificial leveling after fixing instrument again, Comparision is loaded down with trivial details; In the time of leveling, adopt repeatedly expansion bracket supporting leg, or increase the comprehensive leveling of pad in supporting leg bottom, directivity is poor, and leveling difficulty is large; As run into the situation of ground injustice, only leveling work just needs considerable time, affects very much working efficiency.
Though there are some self-leveling tripods in prior art, it mostly is accurate devices such as adopting sensor and processor and realizes leveling, its complex structure, and price is high, and leveling precision is affected by environment, easily makes mistakes; In engineering, as used under field survey environment time, easily damage.
Summary of the invention
The purpose of this utility model is to provide a kind of tripod of semi-automatic leveling, has solved the problem that in prior art, manual leveling and automatic leveling tripod exist, and has improved to a certain extent the efficiency of measuring.
In order to realize above-mentioned task, the technical solution adopted in the utility model is:
A tripod for semi-automatic leveling, comprises base, and base bottom margin is hinged with foot rest, and foot rest lower limb is installed three supporting legs; In three supporting legs, at least two supporting legs are connected with foot rest by connector, connector comprise fixed plate with vertical through fixed plate and with the movable transmission shaft being connected of fixed plate, fixed plate is fixed on foot rest lower limb; Motor is installed on foot rest, and the output shaft of motor and one end of transmission shaft are coaxially fixed, and the other end of transmission shaft is coaxially consolidated with screw rod, and the end of supporting leg is along leg shaft to offering the screw coordinating with screw rod.
Further, be provided with level indicator on base upper surface, level indicator comprises the level board parallel with base upper surface, and the upper surface of level board is provided with levelling bubble, and one end of level board is connected to base upper surface by rotating shaft.
Further, described motor adopts linear motor, and the power supply of motor is rechargable power supplies, and power supply is fixed in base lower surface.
Further, in three supporting legs of tripod, wherein any two supporting legs are connected with foot rest by connector.
Further, the length of described screw is not less than the length of screw rod.
The utility model utilizes the cooperation of motor, screw rod and level indicator to realize the semi-automatic leveling of tripod, and it is simple in structure, easy and simple to handle, steadiness is good, not fragile, the very big workload that has alleviated surveying work personnel, improve working efficiency, for follow-up work is laid a good foundation.

Embodiment
Defer to technique scheme, as shown in Figure 1 to Figure 3, a kind of tripod of semi-automatic leveling, comprise base 1, base 1 bottom margin is hinged with foot rest 2, and foot rest 2 arranges three, be distributed in three directions of base 1 bottom, be used for installing three supporting legs 12, control the folding of supporting leg 12, supporting leg 12 is arranged on foot rest 2 lower limbs.
Because tripod 2 is by supported at three point, therefore, in leveling process, keep a supporting leg 12 motionless, can complete the leveling of instrument by another two supporting legs 12.In this programme, be provided with connector construction, for adjusting the length of supporting leg 12.
In three supporting legs 12 of tripod 2, wherein any two are connected with foot rest 2 by connector, and another one is fixedly mounted on foot rest 2.Connector comprises fixed plate 5, with vertical through fixed plate 5 and with the movable transmission shaft being connected 13 of fixed plate 5; Movable connection refers to that transmission shaft 13 and the relative position of fixed plate 5 do not change, but transmission shaft 13 can be along its circumferential rotation.Fixed plate 5 is fixedly mounted on the lower limb of foot rest 2, and in the inner side of foot rest 2, motor 7 is installed.Motor 7 adopts linear motor, and its power supply 8 adopts rechargable power supplies, and power supply 8 is fixed on the bottom surface of base 1, controls operation and the clockwise and anticlockwise of motor 7 by two groups of switch k1, k2, and Fig. 4 is the circuit diagram that a kind of motor 7 is controlled.
The output shaft 6 of motor 7 is coaxially fixed with one end of transmission shaft 13, and the other end of transmission shaft 13 is coaxially consolidated with screw rod 4.In the time that the output shaft 6 of motor 7 rotates, transmission shaft 13, screw rod 4 and motor 7 output shaft 6 rotating in same directions.The screw 3 coordinating with screw rod 4 along axially offering of supporting leg 12 in the end of supporting leg 12, the length of screw 3 is not less than the length of screw rod 4, in the time that screw rod 4 rotates, screw rod 4 is advanced or retreats with respect to the bottom of screw 3, increase or reduce the distance between supporting leg 12 ends and foot rest 2, having realized the adjustment of supporting leg 12 length.
In order more accurately instrument to be carried out to leveling, in the utility model, be also provided with level indicator structure, coordinate leveling with motor 7.On base 1 upper surface, be provided with level indicator, level indicator comprises the level board 9 parallel with base 1 upper surface, and the upper surface of level board 9 is provided with levelling bubble 10, and one end of level board 9 is connected to base 1 upper surface by rotating shaft 11.In the time not installing instruments, level board 9 is threaded in base 1 upper surface, do not affect carrying and the storage of tripod 2; While installing instruments, level board 9 is rotated outside base 1 upper surface, do not affect the fixed installation of instrument.Because level board 9 is parallel with base 1 upper surface, therefore, in leveling process, only need, in the time adjusting supporting leg 12 length with motor 7, taking levelling bubble 10 as reference, can complete easily leveling work, greatly improve leveling efficiency.
