Abstract
The utility model discloses a movable bayonet device of an angle square. The movable bayonet device of the angle square comprises a angle square bracket, and is characterized in that a transmission tension arm rod is in sliding connection with the angle square, one end of the transmission tension arm rod is in rotary connection with one end of a folding rod through a first bearing, and the folding rod is in rotary connection with the angle square bracket through a second bearing. The movable bayonet device of the angle square has the advantages that a higher measuring precision and operating space are provided for measuring a contracted pipe diameter in a big well chamber, the operating efficiency is greatly improved, and the effectiveness of data is enhanced.
Description
Technical field
The utility model device relates to rain sewer line fields of measurement, is specifically related to a kind of rain sewer line and measures the movable bayonet socket device of the angle square of manually touching use when surveying.
Background technology
The rain sewer line is measured, and is an indispensable part in the engineering survey.Its work purpose is in order to satisfy the Drainage Design needs, existing unwatering system to be carried out absolute altitude, and the detailed measurements of caliber is the measurement achievement that design and unit in charge of construction provide the most accurate caliber, absolute altitude, the draining flow direction.
Because the rain sewer line all is underground laying, since approving and initiate a project since then, all be that to drive a well with the scene that lid uses the inspection shaft angle square manually to touch and survey be that main metering system is (though there is geophysical prospecting method, but can't reach the high precision of manually touching survey), so angle square is very important as the important tool of manually touching survey to its improvement.
In rotating detection process, in the inspection shaft measuring process to little well lid (general Cover of inspection well all is a fixed measure), Da Jing chamber, common angle square can't record desirable data, and its reason is: pipe is embedded in edge, well chamber, with the well lid projected position very big distance is arranged, and angle square leading portion size is subjected to the well lid size restrictions (if the leading portion size is oversize, angle square can't stretch into inspection shaft inside), so run into such situation usually, can only mark: the draw, reference data is provided, can't submits accurate measurement achievement to.This is the limitation that reason caused of survey instrument.
Summary of the invention
The purpose of this utility model is to provide a kind of angle square movable bayonet socket device, can improve the Da Jing chamber, the measurement accuracy of the sewer pipe caliber of little well lid.
In order to realize this purpose, the technical solution of the utility model is as follows: the movable bayonet socket device of a kind of angle square, comprise the angle square frame, it is characterized in that driving force armed lever and this angle square frame are slidingly connected, one end of this driving force armed lever is rotationally connected by an end of clutch shaft bearing and folding rod, and folding rod also is rotationally connected by second bearing and angle square frame.
In use, folding rod is folding, the sectional area of angle square is reduced to minimum angle square and stretches into inspection shaft, when the well in-house operation, drive folding rod and rotate, thereby the bayonet socket device is opened, workbench is expanded to maximum by the driving force armed lever, be the draw and little well lid, the inspection shaft investigation of Da Jing chamber provides the condition of accurate measurement, promotes operating efficiency, guarantees the validity of data.Advantage of the present utility model is to provide higher measuring accuracy and operating space to the indoor draw Calibration of big well, has improved operating efficiency greatly, has increased the validity of data.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
The movable bayonet socket device of a kind of angle square, comprise angle square frame 1, it is characterized in that driving force armed lever 2 and this angle square frame 1 are slidingly connected, an end of this driving force armed lever 2 is rotationally connected by the end of clutch shaft bearing 3 with folding rod 4, and folding rod 4 also is rotationally connected with angle square frame 1 by second bearing 5.According to an embodiment of the present utility model, driving force armed lever 2 is positioned at angle square frame 1 top, is provided with a chute 6 in the driving force armed lever 2, is provided with a set bolt 7 in the chute 6, set bolt bottom screw rod is threaded with the angle square frame, and set bolt head projection is positioned at driving force armed lever 2 tops.
During use, the movable bayonet socket device of the angle square that folds is stretched into inspection shaft, when the well in-house operation, driving force armed lever 2 relative angle square framves 1 are pulled outwardly, under the drive of driving force armed lever 2, the end that folding rod 4 is attached thereto also moves upward thereupon, this folding rod 4 rotates around second bearing 5, thereby just the angle square front end is opened fully.Then set bolt 7 is tightened, made driving force armed lever 2 and angle square frame 1 relative fixed, the angle square of expansion can reach 1.5M～2.0M, can carry out conventional caliber then and touch survey work.After finishing using, earlier set bolt is unscrewed, driving force armed lever 2 is pushed away toward angle square frame 1 inside, under the promotion of driving force armed lever 2, the end that folding rod is attached thereto is also drawn back thereupon, and this folding rod is folded between driving force armed lever 2 and the angle square frame 1.
According to an embodiment of the present utility model, driving force armed lever 2 adopts the aluminium alloy rod of a 2000mmX40mmX20mm, and folding rod 1 adopts the steel pole of a 1500mmX40mmX10mm.The utility model is compared with traditional measurement angle square, bigger operating space is arranged and measure radius, can carry out high-precision Calibration to the draw of 1.5M～2.0M, and precision can reach 1～2CM.
Another bolt 8 is to open the excessive guaranteeing role that plays for angle square among the figure.
