Description

Technical Field

[0001] The utility model relates to the technical field of construction measurement, in particular to a multi-angle visual control point device. Background Art

[0002] Survey control points refer to a series of points that are laid out within the area to be measured before surveying to complete the surveying of the entire area. Survey control points include triangulation points, buried stone points, leveling points, independent astronomical points, etc. In construction projects, triangulation and traverse methods are usually used to arrange control points and then conduct surveying and setting.

[0003] The center of the benchmark stone in plane control measurement is the actual position of the control point. All control measurement results, including coordinates, distances, angles, azimuths, etc., are based on the center mark of the benchmark stone. Any displacement of the benchmark stone will make the control measurement results ineffective or greatly affect the accuracy. However, the control measurement of dense and special-shaped construction projects usually requires the first and second level wires to meet the accuracy requirements. If it still does not meet the requirements, the second level wire points can be encrypted. In actual operation, this method has a certain impact on the measurement results due to human factors or equipment factors when setting up instruments and centering poles. The layout results may have cumulative errors due to multiple station setting. During the surveying process, the station setting and point transfer should be reduced as much as possible. When multiple groups of surveyors need to use the same control point, unnecessary manpower and time waste will be caused. Therefore, it is urgent to solve it.

[0030] Example 1

[0031] See also Figure 1-6 As shown:

[0032] The utility model provides a multi-angle visualized control point device, comprising: an operating platform 10, a column 20, a prism observation part and a leveling part.

[0033] Considering that the visualization control point generally needs to be used for a long time, the operating platform 10 is generally buried in the ground, and the column 20 is vertically connected to the center of the operating platform 10; the prism observation part is used for the visualization control point, and the prism observation part and the center of the top of the column 20 form a detachable connection. Since the operating platform 10 has a certain gravity and is used for a long time, considering the geological influence, a slight settlement phenomenon will occur. The leveling part is located at the connection between the prism observation part and the column 20, and is used to adjust the horizontality of the prism observation part.

[0034] By setting up the leveling part, the entire measurement control point can automatically cope with the problem of slight tilt of the column 20 caused by ground subsidence during long-term use, so that the horizontality of the prism observation part is not affected, thereby improving the accuracy of the entire measurement.

[0035] A connection groove 21 is provided at the top of the column 20; the leveling part and the connection groove 21 at the top of the column 20 form a plug-in fit; the prism observation part and the leveling part form a plug-in fit. This connection method is not only convenient for installing and using the leveling part and the prism observation part, but also convenient for replacing the prism observation part according to measurement requirements, thereby improving the use efficiency of the device.

[0036] The prism observation part includes a common prism and a 360° prism. In actual use, the operator can install a common prism or a 360° prism on the top of the column 20 according to the observation requirements. When multi-angle measurement is required, the use of a 360° prism allows multiple groups of measurement personnel to use the same control point, thereby reducing measurement errors, saving manpower and time, and improving the efficiency of the entire measurement.

[0037] The leveling part is mainly composed of a horizontal plate 31 , a connecting block 32 , a connecting tube 35 and an adjusting foot 33 .

[0038] A connecting threaded rod 322 is provided at the top of the connecting block 32; a threaded hole 311 is provided at the center of the lower surface of the horizontal plate 31, and the connecting threaded rod 322 and the threaded hole 311 form a threaded connection, so that the top of the connecting block 32 and the center of the lower surface of the horizontal plate 31 form a detachable connection.

[0039] In actual use, the connection groove 21 is set as a square groove or a round groove; the connection block 32 is set as a square block or a round block, and the bottom end of the connection block 32 is inserted into the connection groove 21. Through such a setting, the operator can replace the connection block 32 in time according to the shape of the reserved connection groove 21 on different columns 20, ensuring that the leveling part is installed more stably on the top of the column 20.

[0040] The bottom end of the connecting tube 35 is vertically connected to the center of the upper surface of the horizontal plate 31; the bottom of the prism or 360° prism is inserted into the connecting tube 35. Bubble levels 34 are provided at the centers of the four sides of the upper surface of the horizontal plate 31; the adjusting feet 33 are distributed at the four corners of the lower surface of the horizontal plate 31, and the adjusting feet 33 can be extended and retracted in the vertical direction. When used in real time, the operator adjusts the length of the adjusting feet 33 and observes the bubble level 34 to make the horizontal plate 31 in a horizontal state, so as to correct the slight deviation of the column 20 caused by ground settlement, and ensure the accuracy of the control point device.

[0041] The adjusting foot 33 is composed of an upper support rod and a lower sleeve rod. The top end of the upper support rod is vertically connected to the lower surface of the horizontal plate 31, the bottom end is nested in the lower sleeve rod and threadedly connected with the lower sleeve rod, and the bottom of the lower sleeve rod is in contact with the top surface of the column 20, and the bottom of the lower sleeve rod is provided with an anti-skid rubber pad 331.

[0042] In actual use, playground personnel adjust the overall length of the adjusting foot 33 by rotating the lower sleeve rod, and the entire adjustment process is simple and convenient.

[0043] A sponge cover 321 is provided on the outside of the connecting block 32, and the connecting block 32 provided with the sponge cover 321 can just form a nested fit with the connecting groove 21, so that the entire leveling part will not shake due to wind at the top of the column 20, and the sponge cover 321 itself has a certain elastic deformation ability, so when the adjusting foot 33 is adjusted, it can also withstand a certain amount of extrusion as the horizontal degree of the horizontal plate 31 is adjusted, and will not affect the adjustment of the horizontal degree of the horizontal plate 31 by the adjusting foot 33.

[0044] The system also includes a fence; the fence is enclosed along the four sides of the operating platform 10, thereby forming a protection around the operating platform 10 to prevent it from being damaged, and a locked opening is provided on the railing to facilitate entry by measurement personnel.

[0045] The device provided by the utility model can achieve excellent results in actual use when the building area is relatively large or the special-shaped building requires multiple groups of surveyors to survey and design.

[0046] By measuring the coordinates of the buried points with known points, each group of surveyors only needs to set up a station at will, and use methods such as rear intersection to look back at the 360° control points to obtain the coordinates and azimuth orientation of the total station. It should be noted that the total station is not set up on the same circle drawn by several backsight control points. The 360° visual control points can save people from setting up prisms at the control points, increasing efficiency. Since orientation can be achieved without setting up prisms, the centering error of the prism pole can be eliminated, increasing the accuracy of measurement and installation.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
