Embodiment Construction
[0016] Such as figure 1 As shown, the utility boiler cold-bent pipe diagonal measuring tool of the present invention includes an end cover 1, and one side of the end cover 1 is provided with a bayonet, and the bayonet is preferably arranged as a groove 2, and the groove 2 is connected to the cold pipe to be tested. The nozzle of the bent pipe is suitable; the center of the end cover 1 is vertically connected with the adjustment rod 3, the center line of the adjustment rod 3 is consistent with the center line of the nozzle part of the cold bent pipe to be checked, and the direction of the adjustment rod 3 is away from the concave One side of slot 2 sticks out. The adjustment rod is consistent with the center line of the end cap, and the end cap is consistent with the center line of the cold-bent pipe at the nozzle when in use.
[0017] The free end of the adjusting rod 3 is a tapered end 4 , and the tip of the tapered end 4 is the tip 5 of the adjusting rod 3 , and the tip 5 i...

The invention discloses a diagonal line measuring tool of a power boiler cold bend pipe. The diagonal line measuring tool comprises an end cover, wherein one side of the end cover is provided with a bayonet, and the bayonet is matched with a pipe port of the cold bend pipe to be detected; the centre of the end cover is vertically connected with adjustment rods, and the adjustment rods deviating from one side of the bayonet stretch out; two pipe ports of the cold bend pipe to be detected respectively correspond to one diagonal line measuring tool of the power boiler cold bend pipe provided by the invention, and each pipe port of the cold bend pipe to be detected is respectively inserted into a groove of the end cover; and working personnel can use measuring tools such as rulers to measure the distance of rod tops of the two adjustment rods, the measured value is compared with the theory corrected value, and the conclusion that whether the quality of the cold bend pipe is qualified to be obtained. The diagonal line measuring tool of the power boiler cold bend pipe provided by the invention does not needs to carry out complicated operation such as working site staking out, and the detection efficiency is improved; and the labour intensity is reduced in detection, thereby accelerating production flow, reducing the production cost, avoiding casual inspection (staking out measurement), causing unacceptable product leave factory phenomenon, and improving ex factory pass rate.
Description
technical field [0001] The invention relates to a quality detection device for a cold-bent pipe of a power station boiler. Background technique [0002] The cold-bent pipes of power plant boilers have small pipe diameters, a large number of bends, and most of them have space rotation angles. At present, the method of judging whether the quality of the bent pipe is qualified is to compare the curvature of the bent pipe and the distance between the two nozzles (the distance between the two nozzles under the state of looking down on the bent pipe) with the Compared with the theoretical value, it can be judged whether the quality of the bent pipe is qualified. The disadvantage of this method is that it is more complicated, it is more troublesome to set out the wire and measure, and the work efficiency is very low. Generally, it is a random inspection in proportion, which may easily cause unqualified products to leave the factory. When the number of bent pipes is large, testing...
