Description

Technical Field

[0001] The utility model relates to the technical field of special equipment detection and measuring tools, in particular to a clamping type detection ruler. Background Art

[0002] Boilers often have high pressure when working and are common pressure vessels. In order to ensure the safe operation of boiler pressure vessels, it is often necessary to inspect various dimensional parameters such as the wall thickness of the boiler and the wall thickness of the connecting pipes. A measuring ruler is often required to measure the inner and outer diameters of the connecting pipes.

[0003] At present, when using existing measuring rulers, the surveyor needs to use the ruler with both hands to measure. During this process, there may be a certain gap in the measurement, which will lead to certain errors in the measurement results. At the same time, when using the measuring ruler for inspection, the surveyor usually needs to operate with both hands and cannot hold the measuring ruler with one hand for measurement. It is inconvenient for workers to record by themselves. Based on this, a clip-on inspection ruler is proposed. Utility Model Content

[0021] like Figures 1 to 4 As shown, the clamping detection ruler of this embodiment includes a fixed plate 1 and a rotating plate 2. The rotating plate 2 is rotatably mounted on the front end of the fixed plate 1. The rotating plate 2 can rotate at the front end of the fixed plate 1. A mounting groove 3 is arranged at the front end of the rotating plate 2. A moving block 4 is slidably mounted on one side of the mounting groove 3. An elastic spring 5 is installed between one end of the moving block 4 and one end of the mounting groove 3. The elastic spring 5 pushes the moving block 4 to realize automatic clamping of the measuring pipe. By rotating the rotating plate 2, the direction in which the elastic spring 5 automatically pushes the moving block 4 can be changed, which is convenient for realizing the measurement of the inner diameter of the pipe. And automatic clamping measurement of the outer diameter, a connecting plate 6 is detachably installed under the movable block 4, and a movable measuring plate 7 is installed at the lower end of the connecting plate 6. A fixed measuring plate 8 is installed at the lower end of the fixed plate 1 on one side of the movable measuring plate 7. When the movable measuring plate 7 and the fixed measuring plate 8 are used in conjunction with each other, the outer diameter of the boiler pipe can be clamped and measured, and a fixed measuring plate 2 9 is installed at the upper end of the fixed plate 1 on one side of the movable measuring plate 7. The fixed measuring plate 2 9 and the movable measuring plate 7 are used in conjunction with each other to clamp and measure the inner diameter of the boiler pipe. A scale 10 is arranged at the front end of the rotating plate 2 above the mounting groove 3.

[0022] Specifically, a rotating rod 11 is installed at the rear end of the rotating plate 2. The rotating rod 11 is rotatably installed on the fixed plate 1 through the mounting hole. The rotating plate 2 can be rotated on the fixed plate 1 through the rotating rod 11, so as to change the pushing direction of the elastic spring 5 on the moving block 4.

[0023] Furthermore, fixing screw holes 12 are symmetrically arranged at the rear end of the rotating plate 2 on both sides of the rotating rod 11, and a limiting screw 13 is installed at the rear end of the fixing plate 1 through the screw hole. One end of the limiting screw 13 extends into the interior of the fixing screw hole 12. By rotating the limiting screw 13, the limiting screw 13 is rotated into the interior of the fixing screw hole 12, thereby achieving the fixation of the rotating plate 2 after rotation.

[0024] Furthermore, sliding grooves 14 are provided at both ends of the moving block 4, and a sliding block 15 is installed inside a sliding groove 14. A guide groove 16 is provided at the lower end of the rotating plate 2, and the lower end of the sliding block 15 extends to the outside of the guide groove 16. The connecting plate 6 is installed at the lower end of the sliding block 15, and the connecting plate 6 is installed on the moving block 4 through the sliding block 15. When the connecting plate 6 is at the bottom, the sliding block 15 is installed inside the left sliding groove 14. When the connecting plate 6 is at the top, the sliding block 15 is installed inside the right sliding groove 14 to prevent the elastic spring 5 from pushing the movable measuring plate 7 on the moving block 4 from being pushed out from the inside of the sliding groove 14.

[0025] Furthermore, the sliding groove 14 and the sliding block 15 are both T-shaped, and the sliding block 15 is installed in the sliding groove 14 with an interference fit.

The movable measuring plate 7 compresses the elastic spring 5 through the connecting plate 6 and the movable block 4, so that the boiler pipe is located between the fixed measuring plate 8 and the movable measuring plate 7, and then release the movable measuring plate 7. Under the push of the elastic spring 5, the movable measuring plate 7 and the fixed measuring plate 8 automatically clamp the boiler pipe. The measuring personnel only need to apply appropriate support force to the fixed plate 1 with one hand, and the boiler needs to be measured. When measuring the inner diameter of the furnace pipe, the plate 2 is rotated so that the guide groove 16 is located at the top, and the rotating plate 2 is fixed with the limit screw 13. Then the sliding block 15 is installed inside the sliding groove 14 on the right, and then the movable measuring plate 7 is pushed to make the movable measuring plate 7 approach the fixed measuring plate 2 9. At the same time, the movable measuring plate 7 compresses the elastic spring 5 through the connecting plate 6 and the moving block 4, and the fixed measuring plate 2 9 and the movable measuring plate 7 are placed inside the boiler pipe to be measured. Under the action of the recovery of the elastic spring 5, the fixed measuring plate 2 9 and the movable measuring plate 7 are in contact with the inner diameter of the boiler pipe. The measurement personnel only need to apply appropriate support force to the fixed plate 1 with one hand and take readings.
