Problems solved by technology

When measurement with a pad is required at each transitional leveling point (called a turning point), the surveyor needs to bend down or squat down to place the pad on a certain point on the ground, and then place the leveling rod on the pad for measurement; After the measurement, put away the ruler and the ruler pad and carry them to the new turning point...; That is to say, it brings inconvenience to the surveyor in terms of carrying and placing the ruler pad, which greatly affects the working efficiency of the leveling survey

Embodiment 1

[0020] like figure 1 As shown: the same as the prior art, there is a circular horizontal base plate 1, three legs 2 are fixedly connected to the bottom of the horizontal base plate 1, and a vertical support 3 is fixedly connected to the top of the horizontal base plate 1, and the top of the vertical support 3 is a spherical surface 4 , the spherical surface 4 can be the outer surface of a sphere or a hemisphere, and the projection of the spherical surface 4 in the lateral direction is a circle. What is different from the prior art is that the lateral width of the vertical pillar 3 is less than the projected diameter of the spherical surface 4 in the lateral direction. Vertical side plates 5 are provided on the opposite sides of the pillar 3, that is, two symmetrically arranged straight plates, and two retaining strips 6 located below the spherical surface 4 are transversely connected to the two straight plates, and the retaining strips 6 are respectively located on the vertical...

Embodiment 2

[0025] like image 3 Shown: the basic structure is the same as that of Embodiment 1, the difference is that the transverse substrate 1 is a triangle, and there is an outwardly extending horizontal plate 8 connected to the upper ends of the two straight plates, and an upwardly extending horizontal plate connected to the outer ends of the two horizontal plates 8. The extended vertical plate 9 , that is, the horizontal plate 8 and the vertical plate 9 form an L-shape, and the leveling rod connector 7 is a hook slot 10 arranged outside the vertical plate 9 .

[0026] Use process such as Figure 4 As shown: the leveling rod 60 is equipped with a tightening lock 11 matched with the hook slot 10. When combining, the leveling scale 60 is placed in the hook slot 10 and tightened after the tightening lock 11, so that the leveling rod 60 is aligned with the vertical It is fixedly connected to the side plate 5, and other usage processes are the same as in Embodiment 1.

Embodiment 3

[0028] like Figure 5 , 6 As shown: the basic structure is the same as that of Embodiment 1, the difference is that the horizontal base plate 1 is a triangle, the vertical side plate 5 is a vertical sleeve with two ends open outside the vertical pillar 3, and the retaining bar 6 is made of bolts or Structures such as bolts are laterally connected to the vertical sleeve, and can be laterally moved, fastened or disassembled relative to the vertical sleeve. Two horizontal plates 8 extending outward are symmetrically connected to the upper end of the vertical sleeve, and vertical plates 9 extending upward are connected to the outer ends of the two horizontal plates 8 . There is a rotation gap between the vertical sleeve and the vertical pillar 3 to ensure that the vertical side plate 5 rotates horizontally relative to the vertical pillar 3, and there are two horizontal plates 8 extending outward symmetrically connected to the upper end of the vertical sleeve. The outer ends of t...

Abstract

The invention discloses a leveling staff support capable of being combined and carried with a staff. The leveling staff support is provided with a transverse base plate. Legs are arranged on the lower surface of the transverse base plate, a vertical strut is arranged on the upper surface of the transverse base plate, a spherical surface is arranged on the top of the vertical strut, the transverse projection of the spherical surface is a circle, the width of the vertical strut is smaller than the diameter of the transverse projection of the spherical surface, vertical side plates are arranged on two opposite sides of the vertical strut, barrier strips which are positioned below the spherical surface are transversely connected with the vertical side plates, leveling staff connecting pieces which are positioned above the spherical surface are connected with the vertical side plates, and the vertical side plates can horizontally rotate relative to the vertical strut. The leveling staff support has the advantages that the leveling staff support is convenient to operate, the measurement precision can be guaranteed, and the operation efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a leveling pad which can be combined and carried with a ruler, which is easy to operate, ensures measurement accuracy and improves work efficiency. Background technique [0002] The traditional level measuring device is composed of a level gauge and a level rod. When measuring, first place the two leveling rods at two points A and Z on the ground (called leveling points), then set the level at the middle position of the two points, and use the horizontal line of sight of the leveling instrument telescope to aim and read Take the elevation values ​​of two leveling rods, and the difference between the measured elevation values ​​is the level difference between two points A and Z on the ground. If the elevation of one point (such as A) is known, the other point can be calculated from the height difference (such as Z) elevation. If it is known that benchmarking poin...
