[0075] combine Figure 4 , the present invention also provides a method for using the above-mentioned closing pipe length measuring device, comprising the following steps:

[0076] Place the spacer 10 respectively on the connection surfaces of the two pipe flanges 40, and make the center of the spacer 10 coincide with the center of the pipe flange 40;

[0077] Insert the fixed probe rod 31 in the fixed tube 12 on one of the spacers 10;

[0078] Adjust the direction of measuring ruler 23, make measuring ruler 23 be perpendicular to the plane that another spacer 10 is in, when the end of measuring ruler 23 can not contact with fixed pipe 12 on another spacer 10, by making measuring ruler 23 and The movable probe rod 32 pre-inserted on the fixed pipe 12 is contacted and overlapped and kept on the same straight line for positioning;

[0079] The position of measuring ruler 23 on semicircle angle plate 21 is fixed by fastening nut 26;

[0080] Measure the distance between the ce...

Abstract

The invention relates to a folded pipe length measuring device and a using method thereof, the folded pipe length measuring device is used for measuring the length of a folded pipe connected to a pipe flange, and the folded pipe length measuring device comprises a supporting seat and a fixed seat connected to the supporting seat; a rotating assembly is movably connected to the interior of the fixing seat, and the rotating assembly comprises a flange positioning part used for fixing the flange and an angle gauge connected to the flange positioning part; and a fastening assembly which can be used for fixing the rotating assembly on the fixing seat. According to the folded pipe length measuring device, the connecting surface of the pipe flange is positioned through the positioning frame, and the probe rods on the angle adjusting assembly are respectively perpendicular to the plane where the other positioning frame is located, so that the distance between the center of the angle adjusting assembly and the contact surface of the positioning frame and the pipe flange can be measured by taking the central point of the angle adjusting assembly as a starting point, the measuring procedure is effectively simplified, and the measuring accuracy of the folding pipe is guaranteed.

Description

technical field [0001] The present application relates to the technical field of pipe connection, in particular, to a closed pipe length measuring device and a method for using the same. Background technique [0002] During the installation and closure of ship pipelines, due to problems such as accuracy, the closure and connection cannot be carried out according to the pre-design. It is necessary to measure and modify the actual connection pipeline according to the actual situation on site. [0003] During the production process of the closed pipe, it is necessary to measure the relative angle between the two pipe flanges, and calculate the length between the two pipe flanges and the pipe fitting based on the standard specification length of the corresponding corner elbow or pipe fitting. [0004] At present, ship closing pipes will appear in all stages of ship construction, and the existing closing pipes are mainly produced by using a closing pipe reproduction machine. How...
