Abstract
The utility model discloses a height fine-adjustment structure of a level, which is characterized in that the height fine-adjustment structure is a threaded sleeve structure which is longitudinally arranged, a level body is supported at the top part of an external threaded sleeve in the threaded sleeve structure, the internal threaded sleeve in the threaded sleeve structure is supported at the top part of the foot stool of the level, and the external threaded sleeve and the internal threaded sleeve are in threaded matching. According to the utility model, the height of the level can be more quickly and accurately adjusted; and when the height fine-adjustment structure is applied in the levelling of a pier body, the levelling process is more convenient, quicker and safer, the levelling accuracy is high, and the third levelling precision requirements of the highway are met.
Description
Technical field
The utility model relates to a kind of spirit-leveling instrument height accurate adjustment structure.
Background technology
Spirit-leveling instrument is highly being measured generally use, and the height of spirit-leveling instrument is regulated and only can be utilized levelling tripod adjustment repeatedly on three feets in the prior art, and this adjustment mode wastes time and energy, and can not guarantee to adjust precision.
There are many projects in the road ditch crossing or bridge projects, including the construction process of high-Dun leveling is particularly important, the current standard of measurement for the high pier methods include: Level down ruler France, Common Total triangle Elevation France, GPS measured directly access or use long emulated tape directly measured, these measurements require high Dun surveyors boarded top, top in the high pier supporting legislation Front leveling rod, thus not only increase due to vertical feet while climbing resulting measurement difficulty, but also to bring a greater measure of security personnel risks.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of spirit-leveling instrument height accurate adjustment structure being provided, so that the height control of spirit-leveling instrument is quick more, precision is higher.Make it can be applied to high pier shaft measurement of the level, make the convenient safety of measuring process, measuring accuracy height, can satisfy the third-class measurement of the level accuracy requirement of highway.
The utility model adopts following technical scheme for the technical solution problem:
The characteristics of the utility model spirit-leveling instrument height accurate adjustment structure are that said height accurate adjustment structure is one to be the screw shell structure of vertical setting; The top of the external thread tube of spirit-leveling instrument body supports in the screw shell structure, the internal thread tube in the screw shell structure is supported on the top of spirit-leveling instrument foot rest; Between said external thread tube and internal thread tube, carry out threaded engagement.
The utility model is applied to high pier shaft measurement of the level to be undertaken by following process:
1, the place that the elevation of top surface of selection and tested member is suitable is set up spirit-leveling instrument and backsight levelling pole respectively; Require the apical side height of tested member and the chi face reading of backsight levelling pole all to be in the scope surveyed of spirit-leveling instrument; The sight line length of spirit-leveling instrument tested member of distance and backsight levelling pole is more or less the same in 1m;
2, utilize the height of the utility model adjustment spirit-leveling instrument, make the end face of tested member and the level mark silk thread height flush in the spirit-leveling instrument;
3, keep the height of adjusted spirit-leveling instrument, transfer spirit-leveling instrument towards the backsight levelling pole to, the respective heights position of level mark silk thread on the backsight levelling pole is backsight point A in definition spirit-leveling instrument this moment;
4, utilize the elevation of the backsight point A on the known water B measurement on schedule backsight levelling pole, the elevation of said backsight point A is the elevation of top surface of tested member.
Compared with present technology, the utility model beneficial effect is embodied in:
1, spirit-leveling instrument height accurate adjustment structure makes the height of spirit-leveling instrument can access adjustment fast, accurately in the utility model, has thoroughly taken on a new look and only can utilize levelling tripod on three feets, to adjust the situation that wastes time and energy and can not guarantee to adjust precision repeatedly in the prior art.
2, the utility model can make high pier shaft measurement of the level need not prop up upright forward sight levelling pole at the end face of tested member, and difficulty and the insecurity avoiding survey crew to ascend a height bringing are very effective.
Description of drawings
Fig. 1 is applied to the reconnaissance position view in the high pier shaft measurement of the level for the utility model;
Fig. 2 is the utility model structural representation;
Label among the figure: 1 spirit-leveling instrument body; 2 external thread tubes; 3 internal thread tubes; 4 spirit-leveling instrument foot rests; 21 backsight levelling poles; 22 tested members; 23 spirit-leveling instruments.
Embodiment
Referring to Fig. 2; Can adjust rapidly and accurately in order to make spirit-leveling instrument 23; Improve the measuring accuracy of spirit-leveling instrument 23, it is as shown in Figure 2 to provide spirit-leveling instrument height accurate adjustment structure in the present embodiment, and height accurate adjustment structure is one to be the screw shell structure of vertical setting; Spirit-leveling instrument body 1 is supported on the top of the external thread tube 2 in the screw shell structure, and the internal thread tube 3 in the screw shell structure is supported on the top of spirit-leveling instrument foot rest 4; In the use, at first adjust spirit-leveling instrument foot rest 4, accurately locate the precise height of spirit-leveling instrument 23 again through the careful adjustment of threaded engagement between double thread sleeve China and foreign countries' thread barrel 2 and the internal thread tube 3 with the coarse adjustment of quick completion to spirit-leveling instrument 23 height.
