Abstract

The utility model provides a double-connection line pendant and belongs to the technical field of device installation. The double-connection line pendant comprises a connecting frame, line pendant bodies, a reference base, a reference line, knot sleeves, an observation hole, a level bubble, a leveling bolt, a ball prism and threading screws. The two line pendant bodies are connected in parallel through the connecting frame (1), the level bubble (7) is arranged in the middle of the connecting frame (1), the reference base (3) is arranged on the upper portion of the connecting frame (1), and the ball prism (9) is arranged on the reference base (3). By using of an industrial-grade total station instrument and the ball prism, the double-connection line pendant can be hung on the erected reference line at a close range, calibrates the reference line directly and accurately, and prevents accumulative error from being produced. Erection accuracy of the reference line (4) is improved by using the industrial-grade total station instrument and the ball prism in combining mode.

Description

A kind of duplex line pendant

Technical field

The utility model belongs to equipment field engineering field, particularly provides a kind of duplex line pendant, the survey instrument when being the datum line calibration.The calibration of datum line when being applicable to cooperate technical grade total powerstation and prismosphere to carry out the equipment installation.

Background technology

In classic method, all fall a calibration by line setting up the datum line calibration, because self there is stochastic error in accurate reference point, manually-operated line pendant to some the time also have a stochastic error, the datum line that particularly hangs is higher and when wind is arranged, more can produce the accumulation of error, make the measurement result deviation larger.The utility model can closely be suspended on and set up on the datum line by the use in conjunction with technical grade total powerstation and prismosphere, directly to the datum line calibration, has avoided the generation of accumulated error.

Summary of the invention

The purpose of this utility model is to provide a kind of duplex line pendant, with the direct measuring basis line of total powerstation, has solved the problems such as the datum line precision is low of setting up.By the use in conjunction with technical grade total powerstation and prismosphere, can closely be suspended on and set up on the datum line, directly to the datum line calibration, avoided the generation of accumulated error.Comprehensive to industry and total powerstation location measurement method.

The utility model comprises: link 1, line pendant 2, reference seat 3, datum line 4, knot cover 5, viewport 6, air level 7, leveling bolt 8, prismosphere 9, threading screw 10.Two line pendants 2 connect side by side by link 1, establish air level 7 in the middle of the link 1, and reference seat 3 is established on top, and prismosphere 9 is placed on the reference seat 3, gets point observation.

Threading screw 10 upper surfaces on prismosphere 9 geometric centers and the line pendant 2 are contour, can accurately record datum line vertical projection position; Change center of gravity by leveling bolt 8 and carry out leveling; Two hanging wires of line pendant are isometric, and two knot covers 5 are contour, thereby so that two lines fall 2 contour, reference seat 3 levels.

Change center of gravity by leveling bolt (8) and carry out leveling.

The utility model is a kind of duplex line pendant, and advantage is that by being combined with technical grade total powerstation and prismosphere, directly accurate calibration datum line 4 has improved datum line 4 and set up precision.

Description of drawings:

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.

Fig. 1 is working state figure of the present utility model.Wherein, link 1, line pendant 2, reference seat 3, datum line 4, knot cover 5, viewport 6, air level 7, leveling bolt 8, prismosphere 9, threading screw 10.

Fig. 2 is vertical view of the present utility model.Wherein, link 1, line pendant 2, reference seat 3, leveling bolt 8.

Embodiment

Using method of the present utility model is:

1, datum line 4 and preliminary the adjustment have at first been set up.

2, a kind of duplex line pendant is hung over as shown in Figure 1 an end of datum line 4.

3, place first prismosphere 9 again by leveling bolt 8, leveling air level 7.

5, read prismosphere 9 coordinates.

6, adjust datum line one end according to coordinate figure, and then adjust as stated above the other end and get final product.
