Embodiment Construction
[0033] Below in conjunction with accompanying drawing, the utility model is described in further detail.
[0034]When measuring the steel pipe, first set the opening clamp base 1 on the position of the steel pipe to be measured, fix the opening clamp base through three fixing screws 5, and make the steel pipe at the geometric center of the jaws of the clamp base as much as possible. There are several sizes and specifications for the open clamp base to choose from according to the needs of measuring steel pipes. Install the measurement base 3 on the open clamp base 1, and fix the two with screws. By adjusting the position of the screw in the screw groove 6, and adjusting the position of the round hole 13 of the measuring base and the position of the screw, the mutual position of the measuring base and the open clamp seat can be adjusted, and the steel pipe is in the geometrical position of the measuring base. center. An annular guide rail 7 is housed on the measuring base, an...

The invention discloses a steel pipe circular cross section contour detection apparatus of an electric power steel pipe tower and a detection method thereof. The apparatus comprises an opening clamp seat, a measure pedestal and a measure arm, wherein the opening clamp seat connects the measure pedestal, and the measure pedestal connects the measure arm. The whole apparatus is fixed on a steel pipe to be measured by the opening clamp seat. The measure pedestal is provided with an annular guide rail. The measure arm rotates around the steel pipe to be measured along the annular guide rail, wherein rotation angle exceeds 120 DEG. The measure arm is provided with three distance sensors uniformly distributed with 120 DEG to respectively measure and record contour curve information of steel pipes to be measured which exceeds 120 DEG. The detection apparatus can be simply and conveniently installed at any place of a steel pipe to be measured. The three distance sensors uniformly distributed with 120 DEG are utilized to rotate more than 120 DEG along the steel pipe to be measured to detect three contours of the steel pipe. Then the three contours data is processed and the three contours are connected to synthetize to complete the contour measurement of the steel pipe cross section to be measured.
Description
technical field [0001] The invention relates to a detection device and a detection method for a steel pipe circle section profile of a steel pipe tower of an electric power iron tower. Background technique [0002] The power transmission process requires a large number of power towers, which are divided into angle steel towers and steel pipe towers. Angle steel towers are mainly used in mountainous areas where transportation is inconvenient. A large number of steel pipe towers with simple structure are used in plain areas. The main structure of the steel pipe tower is a steel pipe, and the tower body uses bolts to connect the steel pipes one by one to erect. The steel pipe is processed by flat cutting, bending, gap welding of the pipe body, welding of the port, the end and the flange, and hot-dip galvanizing on the surface of the steel pipe. The steel pipe is processed by bending, and the rectangular flat plate is bent into a round tube. The specific processing process i...
