Technical Field

The application relates to the field of industrial measurement, in particular to a permanent reference point sampling auxiliary tool.

Background

Before the initial installation of the production line equipment, a permanent reference point is generally buried in the ground to establish an installation reference of the equipment. The variable quantity of the equipment installation precision can be calculated by collecting the three-dimensional coordinate value of the permanent datum point and the characteristic value of the measuring equipment, and the equipment precision maintenance is realized. However, since the permanent installation standard is buried in the ground and covered with a floor tile, and some are higher than the ground and protected by a protective cover, the height of the standard from the ground varies. When the total station or the laser tracker is used for measuring the datum point, the matched datum point acquisition tool is a triangular disc special for measurement, and the problem that the adjustment range of the datum point in height exceeds the maximum adjustment amount easily occurs in the actual measurement process. The existing common solution is to adopt a cushion block and other articles to cushion a triangular plate temporarily, and the method has two problems that firstly, the height of the cushion block is not easy to match, secondly, the cushion block is easy to shake on uneven ground, and errors are easy to occur in the process of repeatedly acquiring permanent datum points, so that the subsequent calculation is directly influenced.

Disclosure of Invention

One of the objectives of the present application is to provide a permanent reference point sampling auxiliary tool, which aims to improve the problem of inaccurate measurement of the existing permanent reference point.

The technical scheme of the application is as follows:

a permanent reference point sampling aid, comprising:

the annular base is of an annular structure, and three conical grooves are formed in the upper surface of the annular base at intervals;

a plurality of bolts mounted at intervals on the bottom of the annular base; (ii) a

The adjusting support is in threaded connection with the bottom of each bolt respectively, and the bottom end of the adjusting support is of a conical structure.

As a technical scheme of the application, the opening direction of the conical groove is perpendicular to the upper surface of the annular base.

As a technical scheme of the application, the distances among the three conical grooves are the same.

As a technical scheme of this application, a plurality of the interval between the bolt is the same.

As a technical scheme of this application, the bolt is three.

The beneficial effect of this application:

in the auxiliary sampling tool for the permanent datum point, the device is of an annular symmetrical structure, when the triangular disc is placed on the device, three adjusting knobs on the triangular disc just fall into three conical grooves of the annular base, and then the triangular disc is installed on the annular base; meanwhile, three bolts are arranged at intervals at the bottom of the annular base, and the axle center points of the three bolts form an equilateral triangle; each adjusting support is in threaded connection and matching with each bolt in a one-to-one correspondence mode, so that the height of the whole device can be adjusted by adjusting the relative height between the bolts and the adjusting supports, and the adjustable height range is 0-60 mm; in addition, the end of the adjusting support, which is in contact with the ground, is of a conical structure, so that the stability of the whole tool in installation and use is guaranteed. Placing a triangular disc with a positioning needle on the device and erecting the triangular disc above a datum point of equipment to be tested; and then, respectively rotating the three adjusting supports until the horizontal bubbles on the triangular disc are positioned at the middle position, namely the triangular disc is leveled, drawing out the positioning needle and placing the reflecting ball on the positioning hole of the triangular disc, wherein the projection of the center position data of the reflecting ball collected by the instrument on the ground is the position of the reference point. Therefore, the heights of the three directions of the triangular disc can be independently and linearly adjusted by respectively adjusting the three adjusting supports at the bottom of the device, so that the adjusting precision is effectively improved, and the adjusting time is greatly reduced. Secondly, the bottom ends of the three adjusting supports of the device are in a conical structure, so that the device can ensure the stability even if the measurement is carried out on uneven ground. Finally, the tapered groove in the upper surface of the annular base of the device effectively improves the stability of the triangular disc mounted thereon. Therefore, the device can effectively improve the sampling accuracy and the measurement efficiency of the permanent reference point, can enlarge the adjustment range of the permanent reference point acquisition tool and ensure the acquisition stability, thereby indirectly improving the accuracy of equipment information acquisition and facilitating the maintenance of equipment.

In the description of the present application, it should be noted that the terms "upper", "lower", and the like refer to orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the products of the present invention are conventionally placed in use, and are used for convenience in describing the present application and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.

Further, in the present application, unless expressly stated or limited otherwise, the first feature may be directly contacting the second feature or may be directly contacting the second feature, or the first and second features may be contacted with each other through another feature therebetween, not directly contacting the second feature. Also, the first feature being above, on or above the second feature includes the first feature being directly above and obliquely above the second feature, or merely means that the first feature is at a higher level than the second feature. A first feature that underlies, and underlies a second feature includes a first feature that is directly under and obliquely under a second feature, or simply means that the first feature is at a lesser level than the second feature.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present application, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
