Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a fixing bracket for a ballast water GRE pipe. Background Art

[0002] GRE pipes are mostly used in ship ballast water systems. Due to the high pressure and large pipe diameter of the ballast water system, the thrust of the water flow blind plate at the pipe elbow is huge. Since there is no standard design criteria, the piping system designers design the bracket based on their own experience, which may result in insufficient or excessive strength of the fixed bracket.

[0003] The existing device does not solve the problem that when replacing the bracket of the GRE pipe, the old bracket is deformed due to long-term use and the old bolts are not removed. The required installation position of the bracket is easily corroded due to being in a wet state for a long time, and the surface is prone to impurities, which affect the installation of the new bracket. When replacing the bracket of the GRE pipe, the bracket needs to be installed upstream of the GRE pipe elbow, and an incorrect installation position may easily cause the bracket to deform or even damage the GRE pipe. The existing bracket form has weak strength and rigidity and is not suitable for use in GRE pipelines. Therefore, the present application provides a fixed bracket for ballast water GRE pipes to meet the needs. Utility Model Content

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] In the above scheme, the GRE tube is clamped by the provided left clamping plate and the right clamping plate. After clamping, the old bolt is moved upward by rotating the grip. After the old bolt is separated from the old bracket, the slider is moved downward by the telescopic spring rod to reset the grip, and then the push plate is moved backward along the GRE tube by rotating the limit bolt to push the old bracket away from the desired bracket position, thereby solving the problem that the old bracket is deformed due to long-term use and the old bolt is not removed when the bracket of the GRE tube is replaced. The device can be fixed on the front end of the old bracket, and the old bolt can be removed by rotating the grip, and the old bracket can be pushed away from the desired bracket position for subsequent installation of the new bracket, which greatly reduces the time required for bracket replacement. The cleaning shaft and the cleaning roller can be rotated to grind and clean the desired bracket position of the GRE tube, and the rust remover can be sprayed on the surface of the GRE tube through the nozzle, thereby solving the problem that the surface of the desired bracket position is easily rusted due to being in a wet state for a long time and impurities are easily present on the surface, which affects the installation of the new bracket. The rust remover can be sprayed on the desired bracket position and its surface can be polished and cleaned at the same time, which greatly enhances the bracket installation efficiency.

[0020] The zinc block can be used to protect the installed new bracket to reduce the rust of the new bracket after installation. After cleaning, the gear bolt is rotated to separate the upper gear and the lower gear from the GRE pipe. The fixed shaft is passed through the left fixed shaft seat, the rotating shaft seat, and the right fixed shaft seat at the same time, and then the fixed shaft is rotated to prevent it from falling off. After cleaning the mounting bracket on the surface of the GRE pipe, the fixed shaft is rotated to dock the upper clamp with the mounting bracket required for the GRE pipe. After docking, the clamp bolt is rotated to clamp the GRE pipe with the lower clamp to fix the new bracket. This solves the problem that when the bracket of the GRE pipe is replaced, the bracket needs to be installed upstream of the GRE pipe elbow, and the installation position is wrong, which may cause the bracket to deform or even damage the GRE pipe. The effect of fixing the upper clamp above the GRE pipe by pressing the left and right clamps against the front end of the old bracket, pushing the old bracket away from the installation position, and then rotating the fixed shaft to fix the upper clamp above the GRE pipe and then installing the bracket is achieved, which greatly enhances the service life of the bracket.

[0021] By separating the rotating shaft seat from the upper clamp and then rotating the fixing bolts, the left and right clamps can be separated from the GRE pipe. By keeping the model and specifications of the angle steel unchanged, the span between the rib plate three and the rib plate four is reduced, and the rib plate one and the rib plate two under the pipe clamp are aligned with the rib plate three and the rib plate four of the bracket respectively, so that the force on the pipe is directly transmitted to the upper rib plate. The thrust angle steel is added in the reverse direction of the water flow and arranged on the back of the upper rib plate. This structure can directly resist the axial thrust of the pipe. In order to reduce the space occupied by the bracket, the thrust angle steel can be arranged at an angle greater than or equal to 20 degrees with the upper rib plate, which solves the problem that the existing bracket form has weak strength and rigidity and is not suitable for use in the GRE pipeline. The thrust angle steel can offset the deformation influence of the blind plate force on the bracket and the upper and lower rib plates can be aligned to enhance the strength of the bracket, thereby greatly enhancing the service life of the bracket.

[0022] In summary, the utility model has the advantages of being easy to dismantle the old bracket and being able to locate the required installation position of the new bracket, as well as enhancing the strength and rigidity of the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] By placing the left clamping plate 1 at the front end of the old bracket, the left clamping plate 1 and the right clamping plate 3 are clamped together with the GRE tube 32 by rotating the fixing bolt 2. After clamping, the handle 17 is moved upward to make the docking structure dock with the upper end of the bolt of the old bracket. The old bolt is moved upward by rotating the handle 17.

The rust remover can be supplied to the water distributor 29 through the water outlet pipe 28, and then the rust remover can be sprayed on the surface of the GRE pipe 32 through the nozzle 30, thereby solving the problem that the surface of the required installation bracket position is easily rusted due to being in a wet state for a long time and the surface is prone to impurities, which affects the installation of the new bracket. The rust remover can be sprayed on the required installation bracket position and its surface can be polished and cleaned at the same time, which greatly enhances the bracket installation efficiency.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, a fixing bolt 2 is threadedly penetrated at the lower end of the left side of the left clamping plate 1, and a right clamping plate 3 is threadedly penetrated by the left clamping plate 1 through the fixing bolt 2.

The right end surface of the fixed rotating shaft 4 is threaded, and a left fixed shaft seat is provided on the upper surface of the left clamping plate 1. The left clamping plate 1 is rotatably connected with the fixed rotating shaft 4 through the left fixed shaft seat. The right end thread of the fixed rotating shaft 4 penetrates the limiting block 5, and the surface of the fixed rotating shaft 4 is rotatably connected with a rotating shaft seat 6, and the upper surface of the rotating shaft seat 6 is clamped with an upper A clamp 7, a clamp bolt 8 is threadedly penetrated through the left side of the upper clamp 7, a lower clamp 9 is threadedly penetrated through the clamp bolt 8 on the upper clamp 7, an upper rib plate 10 is fixedly connected to the lower surface of the lower clamp 9, and the upper rib plate 10 is provided with rib plate one and rib plate two from left to right, a lower rib plate 11 is fixedly connected to the lower surface of the upper rib plate 10, and the lower rib plate 11 is provided with rib plate four and rib plate five from left to right, a thrust angle steel 12 is fixedly connected to the front end of the upper rib plate 10, an angle between the thrust angle steel 12 and the upper rib plate 10 is twenty degrees, and a docking bolt 13 is penetrated through the internal thread of the lower rib plate 11.

After the surface mounting bracket of the GRE tube 32 is cleaned, the upper clamp 7 is docked with the mounting bracket required for the GRE tube 32 by rotating the clamp bolt 8. After docking, the upper clamp 7 and the lower clamp 9 are clamped to fix the GRE tube 32, which solves the problem that when the bracket of the GRE tube 32 is replaced, the bracket needs to be installed upstream of the elbow of the GRE tube 32.

The problem is achieved by pressing the left clamp 1 and the right clamp 3 tightly against the front end of the old bracket, pushing the old bracket away from the installation position, rotating the fixed shaft 4 to fix the upper clamp 7 above the GRE tube 32, and then installing the bracket. This greatly enhances the service life of the bracket. After the new bracket is installed, the left clamp 1 and the right clamp 3 can be separated from the GRE tube 32 by separating the rotating shaft seat 6 from the upper clamp 7 and then rotating the fixing bolt 2.

[0042] By keeping the model and specifications of the angle steel unchanged, reducing the span between the rib plate three and the rib plate four, and aligning the rib plate one and the rib plate two under the pipe clamp with the rib plate three and the rib plate four of the bracket respectively, the force on the pipe is directly transmitted to the upper rib plate 10, and the thrust angle steel 12 is added in the reverse direction of the water flow and arranged on the back of the upper rib plate 10. This structure can directly resist the axial thrust of the pipe. In order to reduce the space occupied by the bracket, the thrust angle steel 12 can be arranged at an angle greater than or equal to 20 degrees with the upper rib plate 10, which solves the problem that the existing bracket form has weak strength and rigidity and is not suitable for use in the GRE pipeline 32. The thrust angle steel 12 can offset the deformation effect of the blind plate force on the bracket and align the upper rib plate 10 with the lower rib plate 11 to enhance the strength of the bracket, thereby greatly enhancing the service life of the bracket.

The upper gear 23 and the lower gear 25 can be driven to rotate by the rotation of the cleaning shaft 26 and the cleaning roller 27, so that the position of the GRE tube 32 required for mounting the bracket can be polished and cleaned. At the same time, the valve is connected to the external rust remover supply device, and the rust remover can be supplied to the water distributor 29 through the outlet pipe 28, and then the rust remover is sprayed on the surface of the GRE tube 32 through the nozzle 30, so that the problem that the position of the required mounting bracket is easily rusted due to being in a wet state for a long time and impurities on the surface are easy to affect the installation of the new bracket is solved, and the rust remover can be sprayed on the position of the required mounting bracket at the same time. The effect of grinding and cleaning the surface is greatly enhanced, and the bracket installation efficiency is greatly enhanced. The zinc block 31 can protect the installed new bracket and reduce the rust of the new bracket after installation. After cleaning, the gear bolt 24 is rotated to separate the upper gear 23 and the lower gear 25 from the GRE tube 32. The fixed shaft 4 passes through the left fixed shaft seat, the rotating shaft seat 6, and the right fixed shaft seat at the same time, and then the fixed shaft 4 is rotated to prevent it from falling off. After the mounting bracket on the surface of the GRE tube 32 is cleaned, the fixed shaft 4 is rotated to make the upper clamp 7 dock with the mounting bracket of the GRE tube 32. After docking, the clamp bolt 8 is rotated to clamp the GRE tube 32 with the lower clamp 9 to fix the new bracket.The problem that when replacing the bracket of the GRE pipe 32, the bracket needs to be installed upstream of the elbow of the GRE pipe 32, and the wrong installation position may cause the bracket to deform or even damage the GRE pipe 32 is solved. The effect of installing the bracket by pressing the left clamping plate 1 and the right clamping plate 3 against the front end of the old bracket and then pushing the old bracket away from the installation position, rotating the fixed shaft 4 to fix the upper clamp 7 above the GRE pipe 32, and then installing the bracket greatly increases the service life of the bracket. After the installation of the new bracket is completed, the rotating shaft seat 6 is separated from the upper clamp 7, and then the fixing bolt 2 is rotated to separate the left clamping plate 1 and the right clamping plate 3 from the GRE pipe 32. By keeping the model and specifications of the angle steel unchanged, the three and three rib plates are reduced. The span between the four is set, and the ribs 1 and 2 under the pipe clamp are aligned with the ribs 3 and 4 of the bracket respectively, so that the force on the pipe is directly transmitted to the upper rib 10, and the thrust angle steel 12 is added in the reverse direction of the water flow and arranged on the back of the upper rib 10. This structure can directly resist the axial thrust of the pipe. In order to reduce the space occupied by the bracket, the thrust angle steel 12 can be arranged at an angle greater than or equal to 20 degrees with the upper rib 10, which solves the problem that the existing bracket form is weak in strength and rigidity and is not suitable for use in the GRE pipeline 32.
