Description

Ruler pad and ruler integrated device convenient for measuring i angle

Technical Field

The utility model belongs to the technical field of the earth and engineering survey, especially, relate to a ruler pad and ruler disjunctor device of angle of being convenient for survey that effectively improves leveling efficiency.

Background

It is well known that footrests are an important component of leveling devices. The existing ruler pad consists of a hemisphere, a column, a pad body and support legs from top to bottom, and when height difference measurement is carried out, the ruler pad needs to be arranged at a ground measuring point firstly, and then the bottom surface of the leveling staff is arranged on the hemisphere so as to meet the measurement requirement of forming a unique and stable contact point (non-contact surface) between the bottom surface of the leveling staff and the ground measuring point. Before each height difference measurement, the i angle of the leveling instrument (especially the composite leveling instrument) needs to be measured, the specific operation method is that the two ruler cushions are respectively arranged at two measuring points on the ground, the two leveling scaleplates are respectively arranged on the hemispheroid for measurement, and then the two leveling scaleplates are alternately arranged on the hemispheroid for measurement again under the condition that the two ruler cushions do not change in displacement and the like. When measuring at a level point of known elevation, it is also necessary to place the levelling rod directly on the level point without the use of a foot rest, so it is necessary to separate the levelling rod from the foot rest and to maintain the bottom surface of the levelling rod flat. When the height difference is measured, the leveling staff and the ruler pad need to be moved to a station, after the height difference of every two rotating points is measured, the leveling staff of one rotating point needs to be moved to the next rotating point, and the leveling staff of the other rotating point only needs to keep the height unchanged and rotate horizontally (called as a rotating ruler) in situ so that the dividing plane is opposite to the leveling instrument. The traditional ruler pad and the leveling staff are always in a separated state, a measurer needs to bend down or squat down to arrange the ruler pad during measurement, and the ruler pad need to be respectively packed and carried to a new turning point … …; the inconvenience is brought to measuring personnel in the aspects of carrying, arranging and the like of the ruler pad, and the operation efficiency of leveling measurement is greatly influenced.

Chinese patent No. 201620567356.8 discloses a "can make up the leveling ruler pad that carries with the scale", its structure is equipped with vertical curb plate in the relative both sides of stand of ruler pad, has the blend stop that is located the hemispheroid below with vertical curb plate transverse connection, has connect the levelling staff connecting piece that is located the sphere top with vertical curb plate mutually, and vertical curb plate can be to the rotation of stand level mutually, can realize ruler pad and levelling staff combination or separation. Although it is described that "when the foot rest is separated from the leveling staff, it is convenient to store, perform i-angle measurement and non-transitional leveling point measurement of the leveling instrument; when the ruler pad is combined with the leveling staff, the leveling staff can be guaranteed to be arranged on the spherical surface and can be horizontally rotated (rotating the ruler) to carry out transition leveling, the ruler pad and the leveling staff can be integrally carried to carry out continuity moving measurement, the measurement precision is guaranteed, the operation efficiency is effectively improved, but the requirement for exchanging and arranging the ruler pad and the leveling staff when the I angle of the leveling instrument cannot be met by finding the patent in actual operation, namely when the separated leveling staff is arranged on the hemispheroid, the leveling staff is often touched with the arranged vertical side plate or the connecting piece to cause the ruler pad to displace.
