Description

Technical Field

[0001] The invention relates to the technical field of special equipment detection, in particular to an auxiliary device for special equipment detection. Background Art

[0002] Special equipment pressure pipeline inspection refers to the regular or irregular inspection and testing of pressure pipelines in special equipment to ensure their safe operation. This inspection usually includes inspections of the pipeline's appearance, structure, material, wall thickness, etc., as well as non-destructive testing of possible defects inside the pipeline. Internal defects in special equipment pressure pipelines will cause changes in fluid pressure and velocity in the pipeline. By detecting the state of the fluid, it can be determined whether the special pipeline is operating stably.

[0003] The existing internal inspection of special equipment pressure pipelines requires the use of built-in fluid sensors for auxiliary inspection. The fluid sensor is installed by plugging and unplugging. There is a gap between the position where the sensor is installed and the outside of the pipeline. Long-term friction occurs at the position of the gap, which can easily cause the seal of the gap to fail, which can easily lead to fluid leakage inside the pipeline. The fluid sensor is built into the pipeline. After long-term use, the fluid sensor is easily damaged by the impact of the fluid, and the damaged sensor cannot accurately detect the fluid state, which makes the use of special pipelines dangerous.

After the detection is completed, the rotating shaft 36 is reversed to drive the cylinder 24 to rotate back to its original position, so that the detection hole 26 and the opening 25 are staggered, so that the fluid cannot enter the detection hole 26 and contact the sensor 27, so that the sensor 27 can be protected; The adjusting assembly 3 comprises an upper fixing ring 31, which is embedded on the outer wall of the upper end of the flange pipe 1. An upper sleeve 32 is fixedly sleeved on the inner wall of the upper fixing ring 31. A rotating cylinder 33 is rotatably connected inside the upper sleeve 32. An annular groove 34 is provided on the inner wall of the lower end of the rotating cylinder 33. The annular groove 34 is clamped on the surface of the clamping ring 28. A rotating groove 35 is provided at the center of the upper surface of the rotating cylinder 33. A rotating shaft 36 is inserted into the rotating groove 35.

Pull the limiting bar 46 out of the limiting hole blocks 47, and then rotate the rotating bar 41. When the rotating bar 41 rotates, it is restricted by the slider 43 and the arc groove 44 to rotate ninety degrees, and the rotating bar 41 drives the rotating shaft 36 to rotate ninety degrees.

[0018] Specifically, the sealing assembly 5 includes two sealing sleeves 51, which are fixedly connected to the inner walls of the two ends of the flange pipe 1. A plurality of semicircular sleeves 52 are fixedly connected to the inner wall of the sealing sleeve 51 in an annular shape.

Push rods 55 are fixedly connected to the surfaces of two of the arc-shaped gaskets 53 on both sides of the flange pipe 1. Two slide grooves 56 are symmetrically provided on the outer walls of the two ends of the flange pipe 1. The push rods 55 are fixedly connected to the surfaces of the two arc-shaped gaskets 53 on both sides of the flange pipe 1. 5 is slidably connected inside the slide groove 56, and the two ends of the flange pipe 1 are sleeved on the two special pipes, and then the two push rods 55 are pushed to drive the connecting ring 54 to rotate. When the connecting ring 54 rotates, the arc-shaped pad 53 is driven to rotate. When the arc-shaped pad 53 rotates, it will be squeezed into the semicircular sleeve 52. The arc-shaped pad 53 can push the semicircular sleeve 52 to squeeze the sealing sleeve 51 and the special pipe to have an interference sleeve connection. The sealing sleeve 51 is pulled and fits tightly on the pipe, so that the flange pipe 1 is sealed and connected with the special pipe.

[0019] Specifically, the upper end of the cylinder 24 is fixedly connected to the inner wall of the rotating drum 33 , the surface of the cylinder 24 matches the inner wall of the circular groove 23 , and the cylinder 24 is driven to rotate by the rotating drum 33 , so that the cylinder 24 rotates stably in the circular groove 23 .

[0020] Specifically, the detection hole 26 corresponds to the opening 25 , and the detection hole 26 is located at the center of the flange pipe 1 , so that the sensor 27 in the detection hole 26 is located at the center of the fluid, so that changes in the fluid can be accurately received by the sensor 27 .

[0021] Specifically, the upper end of the socket 37 is connected to the rotating groove 35, the upper end of the inserting strip 39 is clamped in the clamping groove 38, and the rotating shaft 36 is connected to the rotating drum 33 through the inserting strip 39, so that the yellow diamond walk 36 can drive the rotating drum 33 to rotate.

[0022] Specifically, the inner diameter of the semicircular sleeve 52 is shorter than the outer diameter of the arc-shaped gasket 53, and the length of the arc-shaped gasket 53 is shorter than the length of the semicircular sleeve 52. When the arc-shaped gasket 53 is squeezed into the semicircular sleeve 52, the semicircular sleeve 52 squeezes the sealing sleeve 51 to deform, so that the sealing sleeve 51 is pulled by the semicircular sleeve 52. The inner wall of the sealing sleeve 51 is pulled and fits tightly on the pipe.

[0023] When in use, firstly, the two ends of the flange pipe 1 are sleeved on two special pipes, and then the two push rods 55 are pushed to drive the connecting ring 54 to rotate. When the connecting ring 54 rotates, the arc-shaped pad 53 is driven to rotate. When the arc-shaped pad 53 rotates, it will be squeezed into the semicircular sleeve 52. The arc-shaped pad 53 can push the semicircular sleeve 52 to squeeze the sealing sleeve 51 and the special pipe to have an interference sleeve connection, so that the sealing sleeve 51 is pulled by the semicircular sleeve 52. The inner wall of the sealing sleeve 51 is pulled and closely fits the pipe, so that the flange pipe 1 and the special pipe are closely connected. The pipeline is sealed and connected, and then the fluid is controlled to flow in the special pipeline and the flange pipe 1. When the fluid state in the special pipeline needs to be detected, the limit strip 46 is pulled out of the limit hole block 47, and then the rotating strip 41 is rotated. When the rotating strip 41 rotates, it rotates ninety degrees through the limit of the slider 43 and the arc groove 44. The rotating strip 41 drives the rotating shaft 36 to rotate ninety degrees. The rotating shaft 36 drives the inserting strip 39 to rotate ninety degrees through the clamping groove 38. The inserting strip 39 drives the rotating drum 33 to rotate ninety degrees. When the rotating drum 33 rotates, it drives the internal The fixed cylinder 24 rotates, and the cylinder 24 rotates to drive the detection hole 26 to correspond to the opening 25, so that the fluid flowing through the flange pipe 1 contacts the sensor 27 through the detection hole 26, and the fluid state is detected by the sensor 27 to distinguish whether the pipeline state is safe. After the detection is completed, the rotating shaft 36 is reversed to drive the cylinder 24 back to its original position, so that the detection hole 26 and the opening 25 are staggered, so that the fluid cannot enter the detection hole 26 and contact the sensor 27, so that the sensor 27 can be protected. It is only necessary to rotate the cylinder 24 regularly to detect the fluid in the flange pipe 1, and the service life of the sensor 27 can be greatly extended. The fluid inside the flange pipe 1 will enter between the upper sleeve 32 and the rotating cylinder 33 due to pressure, and then the fluid will squeeze the rubber ring 310. After being squeezed, the rubber ring 310 will be more tightly connected to the top of the upper sleeve 32, and the rotating hole at the upper end of the upper sleeve 32 will be blocked by the rubber ring 310 to prevent the fluid from leaking from the upper section of the upper sleeve 32, which can effectively prevent the fluid in the pipeline from leaking.
