[0028] When the pressure display mechanism of the tensioning oil cylinder of the present invention is in use, the pressure measuring tube 21 is connected to the inner wall of the pressure measuring joint 12, the oil cylinder body 1 is opened, and the oil inlet pipe 11 delivers the hydraulic oil to the inside of the oil cylinder body 1.

[0029] Example 2

[0030] like Figure 5As shown, the agglomeration cleaning device 3 includes a long rod 31, a bottom plate 32, a brush 33, a top plate 34 and an outer pull plate 35. The long rod 31 passes through and is slidably installed at the bottom of the vertical surface of the pressure measuring tube 21. The bottom plate 32 is fixedly installed on the outer wall of the middle end of the long rod 31. The brush 33 is fixedly installed on the outer wall of the long rod 31. The brush 33 contacts the inner wall of the vertical surface of the pressure measuring tube 21, and the brush 33 is made of steel wire. The top plate 34 is fixedly installed on the top of the long rod 31, and the outer pull plate 35 is fixedly installed on the bottom of the long rod 31. After the pressure gauge 25 is installed, the oil installed in the previous stage will remain on the inner wall of the pressure measuring tube 21. The inner wall is not conducive to this measurement, and the outer pull plate 35 is pulled downward. The outer pull plate 35 drives the long rod 31 to move downward, and the long rod 31 drives the bottom plate 32 and the top plate 34 to move downward, and also drives the brush 33 to move downward. The brush 33 cleans the inner wall of the pressure measuring tube 21, and can effectively contact and clean the inner wall of the pressure measuring tube 21, remove the oil or other impurities remaining on the tube wall during previous use, and ensure that the pressure gauge 25 can measure more accurately after installation, avoiding data deviation or misreading due to tube wall contamination, thereby improving the reliability and measurement accuracy of the entire system.

[0031] The agglomeration cleaning device 3 also includes a C-shaped connecting rod 36, a damper 37, a counterweight 38, a traction rope 39 and a scraper 310. The bottom end of the C-shaped connecting rod 36 is fixedly mounted on the bottom of the outer pull plate 35. When cleaning the pipe wall downward, water vapor accumulates on the surface of the pressure gauge 25, resulting in inaccurate readings. The outer pull plate 35 moves downward while driving the C-shaped connecting rod 36 to move downward. The damper 37 is fixedly mounted on the top of the C-shaped connecting rod 36. The C-shaped connecting rod 36 drives the damper 37 to move downward. The counterweight 38 is slidably mounted on the inner wall of the damper 37. The traction rope 39 is fixedly mounted on the outer wall of the counterweight 38. The traction rope 39 is fixedly mounted on the inner wall of the damper 37. The scraper 310 is fixedly mounted on the back of the damper 37. , the scraper 310 contacts the outer wall of the pressure gauge 25, and the damper 37 drives the scraper 310 to move downward. The scraper 310 cleans the water vapor of the pressure gauge 25. At the same time, the cylinder body 1 will vibrate during use, and the vibration will affect the value of the pressure gauge 25. Through the setting of the counterweight 38, when the cylinder body 1 vibrates slightly, the traction rope 39 will drive the counterweight 38 to slide slightly on the inner wall of the damper 37. The traction rope 39 can effectively slow down the sliding speed of the counterweight 38, thereby further reducing the impact of vibration on the pressure gauge 25, ensuring that it can provide stable and accurate readings under various working conditions, which not only further improves the measurement accuracy, but also enhances the stability and reliability of the system.

[0032] When the pressure display mechanism of a tensioning oil cylinder of the present invention is in use, after the pressure gauge 25 is installed, the oil installed in the previous stage will remain on the inner wall of the pressure measuring tube 21, which is not conducive to the current measurement. The outer pull plate 35 is pulled downward, and the outer pull plate 35 drives the long rod 31 to move downward. The long rod 31 drives the bottom plate 32 and the top plate 34 to move downward, and also drives the brush 33 to move downward. The brush 33 cleans the inner wall of the pressure measuring tube 21, can effectively contact and clean the inner wall of the pressure measuring tube 21, and removes the oil or other impurities remaining on the tube wall during previous use, ensuring that the pressure gauge 25 can measure more accurately after installation, avoiding data deviation or misreading due to tube wall contamination, thereby improving the reliability and measurement accuracy of the entire system.

[0033] When cleaning the pipe wall downwards, water vapor accumulates on the surface of the pressure gauge 25, resulting in inaccurate readings. The outer pull plate 35 moves downward while driving the C-shaped connecting rod 36 downward. The C-shaped connecting rod 36 drives the damper 37 to move downward. The damper 37 drives the scraper 310 to move downward. The scraper 310 cleans the water vapor on the pressure gauge 25. At the same time, the cylinder body 1 will vibrate during use, and the vibration will affect the value of the pressure gauge 25. Through the setting of the counterweight 38, when the cylinder body 1 vibrates slightly, the traction rope 39 will drive the counterweight 38 to slide slightly on the inner wall of the damper 37. The traction rope 39 can effectively slow down the sliding speed of the counterweight 38, thereby further reducing the impact of vibration on the pressure gauge 25, ensuring that it can provide stable and accurate readings under various working conditions, which not only further improves the measurement accuracy, but also enhances the stability and reliability of the system.
