Description

Technical Field

[0001] The present application relates to the technical field of deep-sea steel pipe processing, and in particular to a fiber cloth winding device for deep-sea steel pipes. Background Art

[0002] Deep-sea steel pipes are mainly used in marine projects. Due to their special usage scenarios, a layer of fiber cloth is wrapped around the outer surface of the deep-sea steel pipe during production, and then a layer of anti-corrosion coating is applied to the fiber cloth to improve the corrosion resistance of the deep-sea steel pipe.

[0003] In the related art, two groups of support rollers are placed at intervals on the ground at the workstation for winding the fiber cloth. When winding the fiber cloth onto the deep-sea steel pipe, the deep-sea steel pipe is moved to the top of the two groups of support rollers by a gantry crane and the deep-sea steel pipe is placed on the two groups of support rollers. The two groups of support rollers are located on both sides of the deep-sea steel pipe in the axial direction to support the deep-sea steel pipe and drive the deep-sea steel pipe to rotate, and then the fiber cloth is spirally wound on the deep-sea steel pipe. However, since the two groups of support rollers support and drive both sides of the deep-sea steel pipe respectively, in order to ensure the stability of the deep-sea steel pipe during rotation, the fiber cloth will not be wound at the position where the support rollers are located.

[0004] Regarding the above-mentioned related technologies, due to the setting of the supporting roller group, the deep-sea steel pipe cannot be completely wrapped with fiber cloth, and the position of the deep-sea steel pipe without fiber cloth is less corrosion-resistant than the position of fiber cloth, which in turn affects the quality of the entire deep-sea steel pipe. Utility Model Content

[0005] In order to enable the entire deep-sea steel pipe to be wrapped with fiber cloth, the present application provides a deep-sea steel pipe fiber cloth winding device.

[0006] The present application provides a deep-sea steel pipe fiber cloth winding device, which adopts the following technical solution:

[0007] A deep-sea steel pipe fiber cloth winding device comprises a steel pipe support mechanism and a fiber cloth winding mechanism, wherein the steel pipe support mechanism comprises a support assembly inserted into the steel pipe and a movable trolley for driving the support assembly to move, and the fiber cloth winding mechanism comprises a fiber cloth mounting frame and a walking trolley for driving the fiber cloth mounting frame to move along the axial direction of the steel pipe.

[0008] In order to enable the support assembly to stably support the steel pipe after being inserted into the steel pipe, the support assembly includes a cantilever rod inserted into the steel pipe and a hydraulic cylinder installed on the outer wall of the cantilever rod for abutting the inner wall of the steel pipe. The hydraulic cylinders are provided in plurality and are circumferentially spaced apart on the cantilever rod.

[0009] In order to better fit with the inner wall of the steel pipe to form a stable support, the support assembly also includes an abutment arc plate, and the abutment arc plate is arranged on the telescopic rod of the hydraulic cylinder.

[0010] In order to enable the support assembly to drive the steel pipe to rotate so as to wrap the steel pipe with fiber cloth, a mounting base is provided on the mobile cart, the cantilever rod is inserted into and rotatably mounted on the mounting base, and a high-torque motor is provided on the mobile cart to drive the cantilever rod to rotate.

[0011] In order to conveniently install the fiber cloth roll on the fiber cloth installation frame, the fiber cloth installation frame includes a vertical plate installed on the walking trolley and a supporting force arm installed on the vertical plate for placing the fiber cloth roll.

[0012] The top of the supporting force arm is provided with an arc-shaped groove for placing the reel of the fiber cloth roll.

[0013] In order to enable the fiber cloth to be tightly wrapped around the steel pipe, the fiber cloth mounting frame further includes a tensioning shaft located below the supporting force arm for tensioning the fiber cloth.

[0014] The vertical plate is provided with a side plate for mounting the tensioning shaft, and the side plate is provided with a downward pressure spring for driving the tensioning shaft to always have a downward movement tendency.

[0015] In order to make the whole steel pipe suspended in the air to facilitate the winding of the fiber cloth, two groups of steel pipe support mechanisms are provided, and the two groups of steel pipe support mechanisms are symmetrically arranged at both ends of the steel pipe.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] Two sets of steel pipe support mechanisms are located at both ends of the steel pipe, and the support mechanisms are inserted into the steel pipe without occupying the position on the outer surface of the steel pipe, so that the fiber cloth winding mechanism can wrap the entire steel pipe with fiber cloth;

[0018] The hydraulic cylinder drives the abutting arc plate to press against the inner wall of the steel pipe to stably support the steel pipe. When the driving motor drives the cantilever rod to rotate, the steel pipe will also rotate synchronously with the cantilever rod under the action of the hydraulic cylinder and the abutting arc plate. The fiber cloth roll will move along the axial direction of the steel pipe under the action of the walking trolley, and then automatically wrap the fiber cloth around the steel pipe, reducing manpower.

[0019] When the fiber cloth is wound around the steel pipe, the tensioning shaft can exert a tensioning force on the fiber cloth under the action of the downward pressure spring, so that the fiber cloth can wrap the steel pipe tightly after being wound around it;

[0020] When replacing the fiber cloth roll, it is only necessary to use a crane to lift the fiber cloth roll so that the reel on the fiber cloth roll is placed in the arc-shaped groove in the supporting arm, thereby making the replacement of the fiber cloth roll more convenient.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The present application embodiment discloses a deep-sea steel pipe fiber cloth winding device.

The steel pipe support mechanism 1 is provided with two groups, and the two groups of steel pipe support mechanisms 1 are symmetrically arranged, and the two groups of steel pipe support mechanisms 1 are respectively located at both ends of the steel pipe. Some parts of the steel pipe support mechanism 1 can be inserted into the steel pipe, thereby not occupying the space on the outer wall of the steel pipe, so that the fiber cloth winding mechanism 2 can wind the entire steel pipe.

[0028] Since the two groups of steel pipe supporting mechanisms 1 have the same structure, one group of supporting mechanisms is taken as an example for explanation below.

[0029] Reference Figure 1 and Figure 2The steel pipe support mechanism 1 includes a support assembly 11 and a mobile cart 12. The support assembly 11 is mounted on the mobile cart 12 and is in a cantilevered state. The support assembly 11 can be inserted into the steel pipe and support the steel pipe by abutting against the inner wall of the steel pipe through telescopic movement. The mobile cart 12 drives the support assembly 11 to move, so that the support assembly 11 can be completely inserted into the steel pipe during the movement, and can drive the support assembly 11 to move out of the steel pipe after the fiber cloth is wound.

[0030] The support assembly 11 includes a cantilever rod 13, a hydraulic cylinder 14 and an abutting arc plate 15. The cantilever rod 13 includes a cylindrical portion 131 and a square column portion 132, wherein the square column portion 132 is located at one end of the cylindrical portion 131 and the square column portion 132 is integrally formed with the cylindrical portion 131. The cylindrical portion 131 is connected to the mobile flatbed truck 12, and the square column portion 132 is inserted into the interior of the steel pipe. The cylinder body of the hydraulic cylinder 14 is fixedly mounted on the square column portion 132. The abutting arc plate 15 is fixedly mounted on the telescopic rod of the hydraulic cylinder 14, and the arc top of the abutting arc plate 15 is located on the side of the abutting arc plate 15 close to the interior of the steel pipe, and the arc surface of the abutting arc plate 15 can fit the inner wall of the steel pipe. A plurality of hydraulic cylinders 14 are provided, and the plurality of hydraulic cylinders 14 are evenly spaced and arranged along the circumference of the steel pipe in the square column portion 132. A plurality of abutting arc plates 15 are also provided, the number of the abutting arc plates 15 is consistent with the number of the hydraulic cylinders 14 , and the plurality of abutting arc plates 15 correspond one to one to the plurality of hydraulic cylinders 14 .

[0031] Reference Figure 1 and Figure 2 When the support assembly 11 is inserted into the steel pipe, the hydraulic cylinder 14 first drives the contact arc plate 15 to contract, so that a gap is generated between the contact arc plate 15 and the inner wall of the steel pipe; then the moving cart 12 moves to drive the square column 132, the hydraulic cylinder 14 and the contact arc plate 15 to insert into the steel pipe; then the hydraulic cylinder 14 drives the contact arc plate 15 to extend and press against the inner wall of the steel pipe, thereby propping up the entire steel pipe. In addition, in order to increase the friction force after the contact arc plate 15 contacts the inner wall of the steel pipe so that the steel pipe and the contact arc plate 15 are not prone to slipping, a friction pattern is provided on the side of the contact arc plate 15 close to the inner wall of the steel pipe.

[0032] The top of the mobile cart 12 is fixedly installed with a mounting base 16, and the cylindrical portion 131 is inserted into the mounting base 16 and rotated on the base. Then, the cylindrical portion 131 is driven to rotate, which will enable the abutting arc plate 15 to drive the steel pipe to rotate. In order to automatically drive the steel pipe to rotate, a large torque motor 17 is fixedly installed on the top of the mobile cart 12. A chain is sleeved on the motor shaft of the large torque motor 17, and the other side of the chain is sleeved on the cylindrical portion 131, so that the large torque motor 17 can drive the steel pipe to rotate.

[0033] Reference Figure 1 and Figure 3The fiber cloth winding mechanism 2 is located outside the steel pipe, and the fiber cloth winding mechanism 2 can move between the two moving pallets 12 along the axial direction of the steel pipe, and then wind the fiber cloth on the entire steel pipe in coordination with the rotation of the steel pipe.

[0034] The fiber cloth winding mechanism 2 includes a fiber cloth mounting frame 21 and a walking plate trolley 22. The fiber cloth mounting frame 21 is fixedly mounted on the top of the walking plate trolley 22. The walking plate will move along the axial direction of the steel pipe, and the fiber cloth mounting frame 21 is used to place the fiber cloth roll (that is, the rolled fiber cloth, and each roll of fiber cloth has its own reel).

[0035] Reference Figure 1 and Figure 3 The fiber cloth mounting frame 21 includes a vertical plate 23, a support arm 24, a tensioning shaft 25 and a side plate 26. The vertical plate 23 is welded to the top of the walking trolley 22, the support arm 24 is located on the side of the vertical plate 23 close to the steel pipe, and the support arm 24 is welded on the vertical plate 23 for placing the fiber cloth roll. The side plate 26 and the support arm 24 are located on the same side of the vertical plate 23, and the side plate 26 is located below the support arm 24. The side plate 26 is welded to the vertical plate 23, and the tensioning shaft 25 is installed on the side plate 26 to tension the fiber cloth wound on the steel pipe.

[0036] There are two support arms 24, which are arranged at intervals along the axial direction of the steel pipe, and the fiber cloth roll is located between the two support arms 24; the reel on the fiber cloth roll is rotatably installed on the two support arms 24. Among them, the tops of the two support arms 24 are provided with semicircular arc grooves 241 for the reel of the fiber cloth roll to be embedded, and the reel of the fiber cloth roll is limited after being located in the arc groove 241, so that the fiber cloth roll is not easy to roll off the support arms 24 during the process of winding the fiber cloth on the steel pipe.

[0037] Reference Figure 3 and Figure 4 There are also two side plates 26 , which are spaced apart along the axial direction of the steel pipe. The tensioning shaft 25 is located between the two side plates 26 . Connectors 27 are installed at both ends of the tensioning shaft 25 , and the tensioning shaft 25 is installed on the side plates 26 through the connectors 27 .

[0038] Reference Figure 3 and Figure 4The connecting member 27 includes a threaded rod 271, a through rod 272 and abutment block 273. The through rod 272 is located between the threaded rod 271 and the abutment block 273, and the threaded rod 271, the through rod 272 and the abutment block 273 are welded and fixed, and the size of the abutment block 273 is larger than the size of the through rod 272. A threaded hole is provided at the end of the tensioning shaft 25, and the threaded rod 271 is inserted into the threaded hole and threadedly connected to the tensioning shaft 25. An adjustment hole 261 for the through rod 272 to pass through is provided on one side of the side plate 26 close to the tensioning shaft 25. The extension direction of the adjustment hole 261 is the vertical direction, and the hole diameter of the adjustment hole 261 in the horizontal direction is larger than the width of the through rod 272. The abutment block 273 is located on the side of the side plate 26 away from the tensioning shaft 25 and is in a cantilevered state. An abutment plate 28 is welded to the side of the side plate 26 away from the tensioning shaft 25. The abutment plate 28 is located above the abutment block 273. A downward pressure spring 29 is welded to the bottom of the abutment plate 28. The other end of the downward pressure spring 29 is welded to the top of the abutment block 273. Therefore, the tensioning shaft 25 can slide in the adjustment hole 261 under the action of the downward pressure spring 29 and give the fiber cloth a downward tensioning force.

[0039] The implementation principle of the fiber cloth winding device for deep-sea steel pipes in the embodiment of the present application is as follows: before winding the fiber cloth on the steel pipe, the steel pipe is first lifted by the gantry crane, and then the mobile trolley 12 is driven to move and insert the support assembly 11 into the interior of the steel pipe, and then the hydraulic cylinder 14 drives the abutment arc plate 15 to extend and abut against the inner wall of the steel pipe, and then the lifting structure on the gantry crane is removed. Since the support mechanism is inserted into the steel pipe and does not occupy the position on the outer surface of the steel pipe, the entire outer surface of the steel pipe can be wrapped with the fiber cloth.

[0040] When wrapping the fiber cloth, the large torque motor 17 drives the cantilever rod 13 to rotate; and then drives the entire steel pipe to rotate. While the steel pipe is rotating, the walking plate drives the fiber cloth mounting frame 21 to drive the fiber cloth roll to move along the axial direction of the steel pipe, so that the fiber cloth is spirally wound on the steel pipe.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
