Description

Technical Field

[0001] The utility model relates to the technical field of column positioning detection, in particular to a steel column construction detection device. Background Art

[0002] China has made remarkable progress in the field of solar thermal power generation. Solar thermal projects are gradually showing their huge potential and value. As an important part of renewable energy, solar thermal power generation technology uses a concentrating solar collector system to collect and reflect sunlight, heating molten salt to 565°C, storing heat energy through a molten salt energy storage system, and then generating electric energy through a steam power generation system. The concentrating solar collector system consists of tens of thousands of heliostats that reflect and concentrate sunlight to heat the heat storage medium in the collector. As an important load-bearing unit, the azimuth accuracy requirements of the heliostat column are relatively high during installation. When the orientation of the heliostat column deviates, it will affect the efficacy of the heliostat. The angle deviation of the steel column needs to meet the design requirement of ≤±2°.

[0003] Currently, the positioning and installation of the heliostat column usually first determine fixed installation points, and bury the heliostat column vertically at the installation points. When determining the azimuth accuracy, first, a connecting flange is used to connect to the top of the heliostat column. And a compass for determining the installation azimuth angle of the heliostat column is horizontally arranged on one side of the connecting flange. The staff determines the azimuth angle that the front of the heliostat column should face during installation through the pointing azimuth of the compass.

[0004] However, using a compass can only be used to determine the approximate azimuth angle of the heliostat column installation, and the compass needs to be installed on the top of the steel column by the staff during use. Affected by human operation, the positioning accuracy of the azimuth angle of the heliostat column during installation is not high, affecting the first acceptance pass rate. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the problems in the prior art and provide a steel column construction detection device to accurately detect and determine the azimuth angle of the steel column.

[0006] The utility model provides a steel column construction detection device. The RTK surveying instrument is used to measure the azimuth. The first flange is used to connect to the second flange at the top of the steel column. The RTK surveying instrument is fixed on the top of the first flange. One side of the first flange is fixedly connected with a horizontally arranged main rod, which coincides with the diameter extension line of the first flange. The main rod is detachably connected with a plumb bob.

[0007] Preferably, the plumb bob comprises a magnetic attraction block, a connecting line and a hammer body. The main rod is made of iron. The magnetic attraction block is adsorbed above the main rod. A wire hole for the connecting line to pass through is formed in the main rod. The top end of the connecting line is connected to the magnetic attraction block, and the other end is fixedly connected to the hammer body.

[0008] Preferably, an inclined auxiliary rod is connected to the side of the first flange away from the main rod, and the auxiliary rod is welded to the first flange.

[0009] Preferably, both the auxiliary rod and the main rod are square tubes.

[0010] Preferably, the length of the main rod is greater than 1 m.

[0011] Preferably, the RTK measuring instrument comprises a head, and the RTK measuring instrument is fixedly connected to the top of the first flange.

[0012] Preferably, a plurality of bolt holes are formed in both the first flange and the second flange, and connecting bolts are arranged in the plurality of bolt holes. The first flange and the second flange are connected by the plurality of connecting bolts.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: A steel column construction detection device of the present utility model determines the due east azimuth of the installation hole through the RTK measuring instrument on the first flange and determines it by distance measurement with a steel ruler. The first flange and the second flange are detachably connected, which is convenient for the measurement work. By horizontally arranging the main rod on one side of the first flange and cooperating with the plumb bob to generate a projection on the ground, the plumb bob is detachably installed on the main rod, and it is convenient to separate the plumb bob from the main rod after the measurement is completed, which is convenient for disassembling and moving the whole device. When it is necessary to measure the azimuth angle of the steel column, initially measure 1 m in the due east direction of the steel column through the RTK measuring instrument, and the construction worker makes a mark on the ground and marks it as B. After the steel column is inserted into the column hole, connect the first flange and the second flange. At this time, set the plumb bob at 1 m of the main rod, and the plumb bob will form a projection on the ground as A. If the azimuth angle of the steel column deviates, a distance will be generated between point A and point B, and the generated distance is measured with a steel ruler.

[0014] Since the angle deviation of the steel column needs to meet the design requirement of ≤±2°, point B, point A and the center origin of the steel column form a right triangle. Because , so as long as the length of a is less than 34 mm, it meets the allowable deviation of the steel column angle. The measuring device of the present utility model is convenient, fast and highly accurate, is less affected by human operation, improves the first acceptance pass rate, and avoids the occurrence of the reduction of the efficacy of the heliostat caused by the azimuth deviation of the steel column.

[0021] A steel column construction detection device provided by the present utility model, as Figures 1 to 3As shown, the RTK surveying instrument 4 is used to measure the azimuth. The first flange 2 is connected to the second flange 3 at the top of the steel column 1. The RTK surveying instrument 4 is fixed on the top of the first flange 2. One end is fixedly connected to one side of the first flange 2 with a horizontally arranged main rod 5. The main rod 5 coincides with the extension line of the diameter of the first flange 2. The plumb bob 7 is detachably connected to the main rod 5.

[0022] The azimuth and distance are determined by the RTK surveying instrument 4 on the first flange 2. The detachable connection between the first flange 2 and the second flange 3 facilitates the measurement work. By horizontally arranging the main rod 5 and the plumb bob 7 on one side of the first flange 2 to cooperate, a projection is generated on the ground. The plumb bob 7 is detachably installed on the main rod 5. After the measurement is completed, it is convenient to separate the plumb bob 7 from the main rod 5, which is convenient for disassembling and moving the whole device. When the azimuth angle of the steel column 1 needs to be measured, initially, the RTK surveying instrument 4 measures 1 m in the due east direction of the steel column 1. The construction workers make a mark on the ground and mark it as point B. After the steel column 1 is inserted into the column hole, the first flange 2 is connected to the second flange 3. The plumb bob 7 is installed on the main rod 5. The distance between the plumb bob 7 and the first flange 2 is 1 m. The plumb bob 7 will form a projection on the ground as point A. If the azimuth angle of the steel column 1 deviates, there will be a distance between point A and point B. The generated distance is measured with a steel ruler.

[0023] Since the angle deviation of the steel column 1 needs to meet the design requirement of ≤±2°, point B, point A and the center origin of the steel column 1 form a right triangle. Because , so as long as the length of a is less than 34 mm, it meets the allowable deviation of the angle of the steel column 1. The measuring device of the present invention is convenient, fast and highly accurate, and is less affected by human operation. It is convenient, fast and highly accurate, improves the first acceptance pass rate, and avoids the occurrence of the reduction of the efficiency of the heliostat caused by the azimuth deviation of the steel column 1.

[0024] Preferably, as Figures 1 to 2 shown, the plumb bob 7 includes a magnetic attraction block 71, a connecting line 72 and a weight body 73. The magnetic attraction block 71 is adsorbed above the main rod 5. A wire hole is provided on the main rod 5 to facilitate the connecting line 72 to pass through. The top end of the connecting line 72 is connected to the magnetic attraction block 71, and the other end is fixedly connected to the weight body 73.

[0025] When installing the plumb bob 7, the magnetic attraction block 71 is adsorbed on the main rod 5, and the connecting line 72 is installed at the bottom of the magnetic attraction block 71, so that it passes through the bottom of the wire hole provided on the main rod 5 and is connected to the weight body 73, and the weight body 73 is vertically downward. It is directly adsorbed on the main rod 5 through the magnetic attraction block 71, and the setting is simple and convenient for disassembly and storage.

[0026] Preferably, as Figure 1As shown, on the side of the first flange 2 away from the main rod 5, there is an inclined auxiliary rod 6 connected, and the auxiliary rod 6 is welded to the first flange 2.

[0027] The arranged auxiliary rod 6 is welded to the first flange 2, which is convenient for the user to hold and align the first flange 2 with the second flange 3 on the column.

[0028] Preferably, as Figure 1 shown, the length of the main rod 5 is greater than 1 m, and both the auxiliary rod 6 and the main rod 5 are arranged as square tubes.

[0029] The main rod 5 is made of square steel pipe so that the magnetic attraction block 71 can be adsorbed on the main rod 5. The auxiliary rod 6 is of the same model as the main rod 5, which is convenient for procurement and installation. Moreover, the square tube is convenient for welding, and the welding interface is easy to process.

[0030] Preferably, as Figure 1 shown, the RTK measuring instrument 4 includes a head, and the RTK measuring instrument 4 is fixedly connected to the top of the first flange 2.

[0031] For the detection of the coordinate deviation of the column pile center of the steel column 1, since the center of the fixed position of the RTK measuring instrument 4 coincides with the center of the first flange 2, the coordinates can be directly read and recorded on the hand-held device of the RTK measuring instrument 4 and compared with the designed coordinates to determine whether it meets the requirement of the pile center coordinate deviation of ±30 mm. It effectively saves human resources and improves work efficiency.

[0032] Preferably, as Figures 1 to 2 shown, a plurality of bolt holes are provided on both the first flange 2 and the second flange 3, and connecting bolts are provided in the plurality of bolt holes. The first flange 2 and the second flange 3 are connected by the plurality of connecting bolts.

[0033] By matching the arranged plurality of connecting bolts with the bolt holes on the first flange 2 and the second flange 3, the first flange 2 and the head of the RTK measuring instrument 4 are installed on the second flange 3.

[0034] The usage method of a steel column construction detection device of the present utility model is as follows:

[0035] At first, the steel column 1 is measured 1 m in the due east direction by the RTK measuring instrument 4. The construction worker makes a mark on the ground and marks it as B. After the steel column 1 is inserted into the column hole, the first flange 2 is connected to the second flange 3. The plumb bob 7 is installed on the main rod 5, and the distance between the plumb bob 7 and the first flange 2 is 1 m. The plumb bob 7 will form a projection on the ground as A. If the azimuth angle of the steel column 1 deviates, there will be a distance between point A and point B. The distance generated is measured by a steel ruler. Since the angle deviation of the steel column 1 needs to meet the requirement of the design ≤ ±2°, point B, point A and the center origin of the steel column 1 form a right triangle. Since , so as long as the length of a is less than 34 mm, it is within the allowable deviation of the angle of the steel column 1. The measuring device of the present invention will not be affected by the earth's magnetic field, is convenient and fast to use, and has high accuracy, improving the first acceptance pass rate and avoiding the reduction of the efficiency of the heliostat caused by the azimuth deviation of the steel column 1;

[0036] Since the center of the fixed position of the RTK measuring instrument 4 head coincides with the center of the first flange, the coordinates can be directly read and recorded on the RTK measuring instrument 4 hand-held computer, and compared with the design coordinates to determine whether it meets the requirement of the pile center coordinate deviation of ±30 mm. It effectively saves human resources and improves work efficiency.
