The every km of spirit-leveling instrument described in the technical scheme comes and goes altimetry error and is not more than 10mm.
Base described in the technical scheme is mainly by processing after circular steel plate in bottom and the welding of upper circular steel pipe, three triangle steel plates of uniform welding between round steel pipe and circular steel plate, the diameter of the circular steel plate of base is not less than 200mm, the flatness numerical value of base plane is not more than 0.3mm, base upper circular steel tube inner hole is processed into the taper hole of 0~No. 6 Morse's taper, the verticality of base upper circular steel tube inner hole and base plane is not more than 0.1mm, and the height of round steel pipe is not less than 1/3 of mark post length.
Mark post described in the technical scheme is the elongated cylindrical part, and an end is processed into the awl bar with corresponding 0~No. 6 Morse's taper of base round steel pipe endoporus, and the other end is processed equidistant scale.
The beneficial effects of the utility model are:
(1) adopt mohs tapered bore to cooperate at base and mark post, realized the accurate coaxial positioning of base and mark post, base and mark post can be dismantled at any time simultaneously, make things convenient for the transportation of equipment.
(2) base bottom adopts diameter to be not less than 200mm, and flatness numerical value is not more than the circular steel plate of 0.3mm, has effectively increased the contact area with lifting frame test position diamond plate, has guaranteed the accuracy of measuring.
(3) critical part of the present utility model adopts the standard steel to process, and at first, standard steel output is big, and the machining operation is few, and production cost is lower; Secondly,, adopt the standard steel to have certain intensity as the important accessory of surveying instrument, can be indeformable in long-term the use, the precision that assurance is measured can satisfy the requirement of national standard to accuracy of detection; At last, above critical part is the hollow-core construction that steel are formed, and greatly reduces the weight of checkout equipment, has improved equipment the dirigibility of adjusting operation is installed.
