Description

Technical Field

[0001] This application belongs to the field of nuclear power hose braiding angle measurement technology, and particularly relates to a device for measuring the braiding angle of nuclear power hoses. Background Technology

[0002] Nuclear power hoses refer to a specific type of hose or piping system used in nuclear power plants. These hoses are typically used to transport coolants, gases, or other fluids, ensuring the safe and efficient operation of nuclear reactors. Nuclear power hoses play a crucial role in the safe and efficient operation of nuclear power plants. To improve the service life and performance of the hoses, one or more layers of steel wire braided tubing are usually wrapped around the outer layer of the hose during processing.

[0003] During the processing of steel wire braided hoses, the braided layers are typically woven at a balanced angle. Within a certain angle range, a larger braiding angle results in better pressure resistance of the braided layers, leading to better pressure resistance, bending performance, and higher material utilization in nuclear power hoses. In actual processing, operators use calipers to measure the reinforced hoses formed on the production line. However, due to the unique structure of reinforced hoses, the measurement error obtained with general-purpose calipers is relatively large. Furthermore, this process limits the ability to stop production, as the hoses experience continuous and severe vibration and movement during forming, making measurement even more difficult. Summary of the Invention

[0004] The purpose of this application is to provide a measuring device for the braiding angle of nuclear power hoses, which solves the problem that it is inconvenient to measure the braiding angle of steel wires during hose processing in the prior art.

[0020] The following detailed description provides further details on specific implementation methods.

[0021] like Figures 1 to 7 As shown, this application provides a measuring device for the braiding angle of a nuclear power hose, including a first connecting plate 1, a second connecting plate 2, a sector plate 3, and a measuring caliper 4. The first connecting plate 1 and the second connecting plate 2 are located on both sides of the sector plate 3, and the first connecting plate 1 and the second connecting plate 2 are connected by a connecting strip 11. Both the first connecting plate 1 and the second connecting plate 2 are provided with fixing components for fixing the hose.

[0022] The measuring caliper 4 is rotatably connected to the center position of the sector plate 3. The first connecting plate 1 and the second connecting plate 2 are provided with adjustment components for adjusting the position of the sector plate 3. The adjustment components include adjustment blocks 6 installed on the first connecting plate 1 and the second connecting plate 2, and the other side of the adjustment blocks 6 is connected to the sector plate 3.

[0023] The fixing assembly includes a locking block 5 slidably mounted on the first connecting plate 1 and the second connecting plate 2, and a first sliding groove 12 disposed on the first connecting plate 1 and the second connecting plate 2. The locking block 5 can stably position the device on the hose to be tested, better keeping it stationary during the hose forming process, facilitating the operator to measure the wire braiding angle and ensuring the accuracy of the measurement results.

[0024] When measuring the angle of the steel wire braid on a flexible hose, place the device on the hose to be tested and fix the device to the hose using the locking block 5. Move the adjusting block 6 so that the position of the straight scale line on the sector plate 3 is parallel to the axis of the hose to be tested. Rotate the measuring caliper 4 so that the measuring caliper 4 is consistent with the angle of the steel wire braid on the hose. Read the corresponding degree on the sector plate 3 at this time, which is the angle of the steel wire braid.

[0025] The locking block 5 is provided with a first slider 51, which is adapted to the first slide groove 12. The first slider 51 is connected to the first slide groove 12 through an elastic element 54, which is preferably a spring. A limit baffle is provided on the edge of the first slide groove 12 to prevent the first slider 51 from disengaging from the first slide groove 12. The first connecting plate 1 and the second connecting plate 2 are provided with an elongated groove 13. The locking block 5 is provided with a fixing screw 52. A first wing nut 7 is installed at one end of the fixing screw 52 that passes through the elongated groove 13. The first wing nut 7 is adapted to the fixing screw 52.

[0026] It should be noted that the part of the first connecting plate 1 and the second connecting plate 2 that contacts the hose is the first arc segment 14, and the locking block 5 is provided with the second arc segment 53. The central axes of the first arc segment 14 and the second arc segment 53 coincide on the projection plane of the sector plate 3. When fixing the device to the hose, pull the locking block 5 backward and place the hose between the locking block 5 and the first connecting plate 1 and the second connecting plate 2. Move the locking block 5 to keep the hose stable on the first connecting plate 1 and the second connecting plate 2. Rotate the first butterfly nut 7 to keep the locking block 5 fixed to the first connecting plate 1 and the second connecting plate 2 respectively. At this time, the first arc segment 14 and the second arc segment 53 are respectively in contact with the hose, thereby ensuring the stability of the first connecting plate 1 and the second connecting plate 2 and the hose to be tested, and improving the accuracy of the test results.

[0027] The device is easily installed onto the hose via the elastic element 54, and the locking block 5 automatically engages with the hose, making it convenient for the operator to install and fix.

[0028] The adjustment assembly includes a second slide groove 15 disposed on the first connecting plate 1 and the second connecting plate 2. An adjusting block 6 is adapted to the second slide groove 15. A connecting bolt 61 extends outward from the adjusting block 6. A mounting hole 31 is disposed on the sector plate 3. The connecting bolt 61 is adapted to the mounting hole 31. A second wing nut 8 is installed on the end of the connecting bolt 61 extending outside the sector plate 3. An angle scale 32 is disposed on the sector plate 3. A first through groove 33 is formed on the horizontal scale of the sector plate 3. A second through groove 41 is formed on the measuring caliper 4. When measuring the angle of the steel wire braid, the caliper 4 is used to measure the angle of the steel wire braid. The first through groove 33 detects that the horizontal scale of the sector plate 3 is at the same height as the axis of the hose, and adjusts it so that the horizontal scale line below the first through groove 33 is parallel to the axis of the hose. If the two are not parallel, the adjusting block 6 drives the sector plate 3 to move a certain distance on the first connecting plate 1 and the second connecting plate 2 to make them parallel. After adjustment, rotate the measuring caliper 4 to align the second through groove 41 with the steel wire, and make the straight section of the measuring caliper 4 parallel to the deflection angle of the steel wire. At this time, fix the measuring caliper 4 and read the corresponding angle on the angle scale 32, which is the angle of deflection of the steel wire on the hose.

[0029] A hand handle 16 is provided on the side of the first connecting plate 1 away from the second connecting plate 2, so that the inspector can hold the handle for inspection.

[0030] Preferably, the outer edges of the first connecting plate 1, the second connecting plate 2, the card block 5, etc. are all provided with rounded corners to avoid scratching the operator.

[0031] In use, the device is connected to the first connecting plate 1 and the second connecting plate 2 via the locking block 5, thus fixing the device to the hose to be tested. The adjusting block 6 is moved so that the horizontal scale of the first through-groove 33 detecting the sector plate 3 is at the same height as the hose's axis, and adjusted so that the lower horizontal scale line of the first through-groove 33 is parallel to the hose's axis. After adjustment, the measuring caliper 4 is rotated to align the second through-groove 41 with the steel wire, making the straight section of the measuring caliper 4 parallel to the deflection angle of the steel wire. At this point, the measuring caliper 4 is fixed, and the corresponding angle on the angle scale 32 is read, which is the angle of deflection of the steel wire on the hose. The locking block 5, the first arc segment 14, and the second arc segment 53 are respectively attached to the hose, allowing the device to be stably positioned on the hose to be tested. This better maintains stillness with the hose during the tube forming process, facilitating the operator's measurement of the steel wire braiding angle and ensuring the accuracy of the measurement results. The elastic element 54 facilitates the installation of the device onto the hose, with the locking block 5 automatically attaching to the hose, making installation and fixation convenient for the operator.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application.
