Summary of the invention
The utility model is in order to solve the existing above-mentioned technical problem of prior art, provides that a kind of automaticity is high, processing ease, can effectively improve the measurement foot rest with self leveling function of measuring efficient and precision.
Technical solution of the present utility model is: a kind of measurement foot rest with self leveling function, be provided with apparatus installation pedestal and leg, be connected to circular connecting frame with described leg upper end, described circular connecting frame is laterally inboard to be flexibly connected by the first axle and interior ring, interior ring is laterally inboard to be flexibly connected by the second axle and apparatus installation pedestal, and described the first axle and the second axle differ 90 degree in the horizontal; The active connection place of the active connection place of described the first axle and interior ring and the second axle and apparatus installation pedestal is provided with rotary locking device.
Described apparatus installation pedestal is joined by the balancing weight of the apparatus installation body on top and bottom and consists of.
Be connected by at least two ball screws between the apparatus installation body of described apparatus installation pedestal and balancing weight, be fixedly connected with dip sensor on the apparatus installation body, dip sensor output is joined with control module, control module output is joined with motor, the screw mandrel of machine shaft and ball screw joins, the apparatus installation plane parallel at the plane that two sensitive axes of described dip sensor consist of and apparatus installation body top, and wherein a sensitive axes and the two ball screws centre of projection line on the apparatus installation plane parallels.
The center of described apparatus installation pedestal is provided with the circular hole of up/down perforation.
The bottom of described balancing weight is provided with the ring bodies that is threaded.
The utility model is that the scaffold with normal flat function has been installed between apparatus installation pedestal and leg, can rely on gravity to realize the leveling of surveying instrument, need not manual operation, automaticity is high, has processing ease, improves advantages such as measuring efficient and validity.Especially be provided with dip sensor, motor, ball screw etc., can further realize the leveling automation, further improve the precision of leveling and measure efficient, to be applicable to the highi degree of accuracy precision measuremnt.

Embodiment
Embodiment 1:
As shown in Figure 1, 2, 3: the same with prior art, be provided with apparatus installation pedestal 6 and leg 2, to be connected to circular connecting frame 1 with described leg 2 upper ends with the prior art difference, circular connecting frame 1 is laterally inboard to be flexibly connected by the first axle 3 and interior ring 4, interior ring 4 is laterally inboard to be flexibly connected by the second axle 5 and apparatus installation pedestal 6, and described the first axle 3 and the second axle 5 differ 90 degree in the horizontal; Described the first axle 3 is provided with rotary locking device 9 with the active connection place of interior ring 4 and the active connection place of the second axle 5 and apparatus installation pedestal 6.Apparatus installation pedestal 6 is joined by the balancing weight 8 of top apparatus installation body 7 and bottom and forms, apparatus installation body 7 can be round flat board or round cylinder, balancing weight 8 is round cylinder, and balancing weight 8 bottoms also spiral are connected with ring bodies 14, in order to increase the overall weight of balancing weight 8.
Embodiment 1 operation process is: at first survey crew regulates leg 2 to suitable length, then leg 2 is opened and be placed in terrestrial survey point and go up and unclamp all rotary locking devices 9, make apparatus installation pedestal 6 under Action of Gravity Field, automatically be in Anping state after several seconds, at this moment, lock all rotary locking devices 9, the top that the surveying instruments such as level instrument, theodolite and electronic tachometer is placed in apparatus installation pedestal 6 can begin to measure.
Embodiment 2:
As shown in Fig. 4,5: basic structure is with embodiment 1, with embodiment's 1 difference be: the apparatus installation body 7 of apparatus installation pedestal 6 and balancing weight 8 are middle circular cylinder with manhole, three ball screws 10 that distribute by equal angles between the two are connected, be fixedly connected with dip sensor 11 on apparatus installation body 7, dip sensor 11 outputs are joined with control module 12, control module 12 outputs are joined with motor 13, and the screw mandrel of motor 13 rotating shafts and ball screw 10 joins.Dip sensor 11 adopts the double-shaft tilt angle sensor SCA103T-D01 of VTI, and control module 12 consists of take the C8051F350 of SILABS as core, and motor 13 adopts stepper motors.The nut of ball screw 10 is fixedly installed in the top of balancing weight 8, and dip sensor 11, control module 12 and motor 13 are fixed in apparatus installation body 7, and motor 13 rotating shafts are fixedly connected with the screw mandrel of ball screw 10.The apparatus installation plane parallel at the plane that two sensitive axes of dip sensor 11 consist of and apparatus installation body 7 tops, and wherein the centre of projection line of two ball screws 10 of a sensitive axes and certain on the apparatus installation plane parallels.
