Abstract

The utility model discloses a multi-purpose leveling instrument and belongs to measuring instruments, aiming to provide a measuring instrument capable of perfroming leveling, slope and orientation measurement in two directions perpendicular to each other at one time. The multi-purpose leveling instrument comprises a main body and horizontal rulers, wherein the main body is formed by connecting a horizontal ruler plate (1) and a vertical ruler plate (5); the three horizontal rulers are arranged on the top surface of the horizontal ruler plate (1), a 90 DGE included angle is formed between the moving direction of air bubbles of the first horizontal ruler (2) and the axial line of the horizontal ruler plate (1), a 45 DGE included angle is formed between the moving direction of air bubbles of the second horizontal ruler (7) and the axial line of the horizontal ruler plate (1), and a 180 DGE included angle is formed between the moving direction of air bubbles of the third horizontal ruler (6) and the axial line of the horizontal ruler plate (1); and a geomagnetic North Pole compass (3) is fixed on the top surface of the horizontal ruler plate (1) with scales, and a gravity pointer (4) is arranged on the vertical ruler plate (5).The multi-purpose leveling instrument provided by the utility model has simple structure, high measuring accuracy, convenience in operation and straightforward reading-out, can be mainly used in reconnaissance and measurement of criminal investigation sites, excavation and measurement of archeological sites, construction works, mechanical processing and the like.

Description

The multi-usage hydrolevelling device

Technical field: the utility model relates to a kind of measuring instrument, and relating in particular to a kind of locating tab assembly that catchments, measurement of bearing and slope measuring is the measuring instrument of one.

Background technology: at present, most of horizontal measuring instruments once can only be measured the degree of tilt of a direction, and can not measure simultaneously by both direction; So when needing to measure the levelness on a plane, then repeatedly measurement update, not only troublesome poeration but also measuring error are big; In addition, traditional horizontal measuring instrument does not have measurement of bearing function and slope measuring function.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide and a kind ofly can either once carry out horizontal survey to two mutually perpendicular directions, again the multi-usage hydrolevelling device in the energy measurement gradient and orientation.

To achieve these goals, the utility model by the following technical solutions: it comprises body and surveyor's staff; Described body is by crossfoot plate and the vertical foot plate T font structure that is formed by connecting, the end face of crossfoot plate is fixed with three surveyor's staffs, and the bubble motion direction of first surveyor's staff becomes 90 °, the bubble motion direction of second surveyor's staff to become 180 ° with the bubble motion direction of the axis of this crossfoot plate angle at 45, the 3rd surveyor's staff with the axis of this crossfoot plate with the axis of crossfoot plate; End face at the crossfoot plate is fixed with the magnetic north north arrow, is provided with gravity pointer vertically downward on vertical foot plate, and the crossfoot plate is provided with scale.

First surveyor's staff, second surveyor's staff are separately fixed near crossfoot plate end positions, and the 3rd surveyor's staff is fixed on the middle position of crossfoot plate; The gravity pointer is located at the position of center line of vertical foot plate.

Compared with the prior art, the utility model is owing to adopted technique scheme, therefore not only once can measure, and can also fix the position and the gradient, have advantages such as simple in structure, easy to operate, that measuring accuracy is high, reading is directly perceived the levelness of orthogonal both direction.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

Among the figure: crossfoot plate 1 first surveyor's staff 2 magnetic north north arrowes 3 gravity pointers 4 vertical foot plates 5 the 3rd surveyor's staff 6 second surveyor's staffs 7

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1～3, crossfoot plate 1 and vertical foot plate 5 are fixedly connected to form the T font structure, and the end face of crossfoot plate 1 is fixed with three surveyor's staffs; Wherein, the bubble motion direction of first surveyor's staff 2 becomes 90 °, the bubble motion direction of second surveyor's staff 7 to become 180 ° with crossfoot plate 1 axis angle at 45, the 3rd surveyor's staff 6 with crossfoot plate 1 axis with crossfoot plate 1 axis; End face at crossfoot plate 1 is fixed with magnetic north north arrow 3, is provided with gravity pointer 4 vertically downward in the front of vertical foot plate 5, and the position corresponding to this gravity pointer on the crossfoot plate 1 is provided with scale.When measuring the gradient, this measuring instrument is inverted the gradient data that the end face of crossfoot plate 1 is positioned over is domatic, vertical foot plate 5 upwards promptly can read the slope downwards.In order to improve measuring accuracy, first surveyor's staff 2 and second surveyor's staff 7 are provided with near the two ends of crossfoot plate 1 as far as possible, and gravity pointer 4 is located at the position of center line of vertical foot plate 5.
