Abstract
The utility model relates to the field of measuring tools, in particular to a survey marker for a subway horizontal control point. The survey marker for the subway horizontal control point is characterized in that the survey marker is composed of a pre-embedded part and a measuring disk. The pre-embedded part is fixedly connected with the measuring disk, and a measuring device is fixedly connected with an upper surface of the measuring disk. The survey marker for the subway horizontal control point has the advantages that the structure is simple and reasonable, and through embedment of the pre-embedded part, measuring and collecting of various data can be completed promptly on a measuring point; each connecting piece has high machining precision, and the obtained data through measurement also has high precision. According to embedded depth, the structures of an overground U-shaped girder of rail traffic can not be damaged. The lower end of the measuring disk is designed to be of a regular hexagon or threaded structure, and therefore measuring errors caused by rotation of a connecting rod in the process of fieldwork can be effectively avoided.
Description
Technical field
The utility model relates to the survey instrument field, is specifically related to a kind of survey mark that is used for the subway planimetric control point.
Background technology
At present, subway plane control point measurement have that observation station is many, measuring task is heavy, high precision and require characteristics such as operation process high automation.When existing measurement mechanism uses; The web member that the measuring equipment of different model all need be through different size and the built-in fitting of different size are accomplished fixing, do not have unified survey mark, thereby measuring task are heavy; Measuring accuracy is affected, the follow-up maintenance difficulty.
Summary of the invention
The purpose of the utility model is the weak point according to above-mentioned prior art; A kind of survey mark that is used for the subway planimetric control point is provided; This sign can be provided with built-in fitting in measurement point; Thereby simplified the installation and the installation accuracy thereof of measuring equipment equipment, make the measurement operation easy, and measuring accuracy has been high.
The realization of the utility model is accomplished by following technical scheme:
A kind of survey mark that is used for the subway planimetric control point; Relate to measuring equipment required in the plane control point measurement; It is characterized in that: described survey mark is made up of built-in fitting, measurement disk; Said built-in fitting is fixedly connected with said measurement disk, and said measuring equipment is fixedly connected on surface on the said measurement disk.
Has a coupling shaft on the surface under the said measurement disk; Said built-in fitting has a hollow cavity; Said built-in fitting is fixedly connected with said measurement disk and refers to: the said coupling shaft on the said measurement disk is plugged in the hollow cavity of said built-in fitting, and said coupling shaft and described hollow cavity structure are complementary.
The inwall of the hollow cavity of said built-in fitting is provided with internal thread, and said coupling shaft is provided with external thread, the mutual threaded engagement of said internal and external screw thread.
The hollow cavity of said built-in fitting is the regular prism structural cavity body, and said coupling shaft is the regular prism body, and said regular prism structural cavity body and said regular prism body are worked in coordination.
The outer wall of described built-in fitting is provided with the lines that is made up of difference of height.
The utility model has the advantages that: simple and reasonable, can on measurement point, accomplish the measurement collection of different pieces of information rapidly through burying built-in fitting underground; Each web member machining precision is high, and the data precision that measures is high.The built-in fitting buried depth is shallow, does not destroy the structure of track traffic ground epimere U type beam and hypomere section of jurisdiction, ground.Measure the disk lower end and be designed to regular hexagon or threaded structure, can effectively avoid rotating the measuring error that causes because of connecting link in the field operation process.

Embodiment
Through embodiment the utility model characteristic and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-4, mark 1-6 is respectively among the figure: measure disk 1, built-in fitting 2, measuring equipment 3, coupling shaft 4, hollow cavity 5, outer wall 6.
Embodiment 1: as shown in Figure 1, present embodiment is made up of measurement disk 1, built-in fitting 2, and wherein measuring equipment 3 is mounted on the upper surface of measuring disk 1.The built-in fitting 2 that is embedded in the planimetric control point measured place in advance is a tube-in-tube structure, and it has hollow cavity 5, and measuring disk 1 bottom is fixed connection shaft 4, and the inwall of hollow cavity 5 is provided with internal thread, threaded engagement between itself and the coupling shaft 4.Measuring equipment 3 can be plane surveying equipment such as GPS, total powerstation or measuring prism.As shown in Figure 4, built-in fitting 2 is used for the measurement of planimetric control point, for forcing the centering sign, can guarantee the accurate of planimetric position, and outer wall 6 adopts the method for the lines that the difference of height formation is set to guarantee friction force, makes it can be anchored on measurement point.After accomplishing the measurement operation, can accomplish sealing through installing capping additional to the hollow cavity 5 of built-in fitting 2, prevent that other foreign matters from getting into.
Embodiment 2: the difference like Fig. 2,3 present embodiments and embodiment 1 is, what hollow cavity 5 adopted is positive six prismatic cavitys, and what coupling shaft 4 adopted is positive hexagonal prism.
The foregoing description is in the specific implementation: on the inwall of the hollow cavity 5 of built-in fitting 2, screw thread is set; Perhaps its hollow cavity is arranged to the regular prism structure; After its role is to make measurement disk 1 to insert built-in fitting 2, can when measuring, keep under the constitutionally stable situation, to be convenient for measuring.
Measure disk 1 in the foregoing description and adopt high-strength aluminum alloy, the independent machining precision of each parts is 0.02mm.And the miscellaneous part except that measuring disk 1 all adopts the stainless alloy material of 1Cr18Ni9, and the independent machining precision of each parts is 0.02mm, to guarantee the accuracy of measurement data.
Obviously it will be appreciated by those skilled in the art that; For in the present embodiment for the selection of hollow cavity 5 and coupling shaft 4 shapes and structure; Its objective is that avoiding the two to cooperate the back to produce axially relatively rotates; Therefore theoretically, so long as not the matching relationship of right cylinder and column type cavity, can satisfy the requirement of present embodiment between the two.Therefore being chosen in this and not giving unnecessary details one by one for other shapes.
