Abstract

The utility model provides a three-dimensional coordinate sampling device for an arc dam model. A bottom sea with adjustable level and a supporting tray which is vertical to a guide post are connected into a whole through a guide post with graduations, and the supporting tray can slide up and down along the guide post; small holes are drilled on the supporting tray, and wire pendants penetrate through the small holes; a semicircle instrument is put with the small holes as a center of circle, and simultaneously, a flexible rule is placed along the radial direction of the semicircle instrument. Height, an angle and a curve radius are simultaneously measured, and the problem that a sampling complex process in the process of making the arc dam model is complex is effectively solved. The device is applied to the sampling processing of the model of the large-sized arch dam and is also suitable for the sampling processing of other complex shape bodies.

Description

Arch dam model three-dimensional coordinate laying out apparatus

The utility model relates to a kind of laying out apparatus of complicated shape object.

Before large-scale water conservancy arch dam is built, need to make earlier an arch dam model, so that provide relevant mechanical property reference experiment data for the formal construction of arch dam.But because arch dam model is the space shell structure, shape is very complicated, when model is amplified sample, the past people complicated grid plan of all will drawing earlier, the sectional making template, also will position by means of level gauge and transit, whole setting-out operation is very numerous and diverse, take a lot of work, time-consuming, still do not have special laying out apparatus at present.

The purpose of this utility model is that a kind of special arch dam model laying out apparatus will be provided, so that large-scale arch dam space shell structure model construction lofting position fixing process obtains simplifying.

The purpose of this utility model is achieved in that the guide pillar vertical with a band scale is installed on the base of a horizon adjustable, be equipped with on the guide pillar and can slide up and down and the pallet vertical along guide pillar with guide pillar, base position below guide pillar is equipped with determines height gauge target benchmark plug, on pallet, be provided with the stringing seat, one stringing screw is arranged in the middle of the stringing seat, in the middle of the stringing screw, bore an aperture, penetrate cotton rope in the aperture, the cotton rope lower end is wired bob, also being equipped with one on the pallet is the graphometer at center with the aperture, along graphometer radially locate to be placed with tape measure, the scale start position of tape measure is at the aperture place.

Because the utility model will be determined the function of height, angle and sweep and roll into one, arch dam model is being carried out in the setting-out process, have simple to operate, easy to use, save time, the characteristics of saving of labor, material-saving, solved the setting-out of large-scale arch dam model complex curve effectively, the problem of a difficulty is looked in space orientation.This device also is applicable to the setting out survey of other complicated shape things except the setting out survey that is applied to large-scale arch dam model.

Fig. 1 is a structure principle chart of the present utility model.

Fig. 2 is the sectional drawing of base among Fig. 1.

Fig. 3 is the sectional drawing of pallet among Fig. 1.

1-guide pillar wherein, 2-base, 3-reinforcing sleeve, 4-benchmark plug, 5-heightens screw, 6-air level, 7-pallet, 8-guide pin bushing, 9-strengthens gusset, 10-keyway, 11-key, the 12-hold-down screw, 13-stringing seat, 14-stringing screw, the 15-cotton rope, the 16-line weighs down, the 17-filler, the 18-graphometer, 19-tape measure, 20-wheel.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

The guide pillar 1 of one band scale is inserted in the reinforcing sleeve 3 that welds or cast on the base 2, base 2 is vertical mutually with guide pillar 1 position, is equipped with guide pillar 1 contacted base 2 positions (be reinforcing sleeve 3 below position) below guide pillar 1 and is used for definite height gauge target benchmark plug 4; Base 2 is shaped as " ∧ " shape, finding out not three points on same straight line on the base 2, be equipped with two at these three some places respectively and heighten the horizontal plane that screw 5 and air level 6 are used for adjusting base 2, side at two end points of " ∧ " shape base 2 is equipped with two wheels 20 respectively, when base 2 contacted with ground, the position that should make these two wheels 20 was a little more than ground; Pallet 7 is passed guide pillar 1 by the guide pin bushing on pallet 78, pallet 7 surfaces are perpendicular with guide pillar 1, guide pin bushing 8 on the pallet 7 is by strengthening gusset 9 and 7 stable connections of pallet, guide pillar 1 side has keyway 10 from top to bottom, stud with the square key 11 that is fixed together with guide pin bushing 8 in the keyway 10, pallet 7 is slided up and down along guide pillar 1; Also be provided with the stringing seat of fixing by hold-down screw 12 13 on the pallet 7, stringing seat 13 middle positions are screwed with stringing screw 14, in the middle of stringing screw 14, be drilled with aperture, penetrating cotton rope 15 in the aperture, is wired bob 16 on the cotton rope 15, makes filler 17 with soft rubber in the stringing seat 13, so that cotton rope 15 has enough friction when pulling, also being equipped with one on the pallet 7 is the graphometer 18 at center with the aperture, radially is placed with invar tape 19 along graphometer 18, and the position of aperture is exactly the start position of invar tape 19 scales.
