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.
