Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of float pipe connecting piece, especially relates to a variable angle float pipe connecting accessory for water platform. BACKGROUND

[0002] At present, the construction of the floating water platform mainly adopts the splicing mode of the floating block, however, the activity plane of this kind of platform is the floating body itself, and there are defects such as lack of offshore stability and too low distance from the water surface. In recent years, in order to overcome these limitations, a new type of platform emerges as the times require, which adopts a flexible pipe closed frame as a floating body, and separates the activity plane from the floating body through a support and increases the height of the activity plane.

[0003] With the continuous expansion of the platform application scene, the demand for the shape of the platform is also increasingly diversified. For example, the ship-shaped platform can significantly reduce the influence of the sea wave force due to its unique shape design, thereby improving the stability and safety of the platform. However, neither the traditional floating block splicing platform nor the pipe frame platform can realize the construction of the platform with a special shape. The reason is that the pipe frame platform needs to connect the floating pipes at multiple special angles, but it is limited to the fact that most of the current floating pipe connecting accessories only provide a connection angle of 135° and 90°, which cannot meet the demand of the multi-angle connection of the platform with a special shape.

[0004] At present, the existing technology realizes the connection of non-standard angles by cutting the pipe section at the required angle and then butt joint, but this method has two problems: first, the sectional area after cutting is greatly different, which may cause insufficient heating in the area with larger area and excessive softening in the area with smaller area, thereby affecting the welding strength; at the same time, the inner corner of the welded pipe forms a sharp corner, which is easy to cause stress concentration and affect the service life. Second, the process is complex and tedious, and the professional technical requirements of the cutting and welding personnel are high, which increases the production cost and difficulty.

[0034] The application is described below Figures 1 to 8 A variable angle floating pipe connecting fitting for a water platform is described in the embodiment of the present application, comprising:

[0035] The first connecting member 100 is provided with a first floating pipe joint 110 and two first connecting arms 120, the two first connecting arms 120 are arranged at intervals, and the two first connecting arms 120 are respectively provided with a first inner spline through hole 130, and the centers of the two first inner spline through holes 130 are on the same straight line; at least one of the first connecting arms 120 is provided with a first connecting flange 140, and the first connecting flange 140 is located at the outer periphery of the side end of the first inner spline through hole 130 away from the other first connecting arm 120.

[0036] The second connecting member 200 is provided with a second floating pipe joint 210 and a second connecting arm 220, the second connecting arm 220 is provided with a second inner spline through hole 230, and the spline grooves of the second inner spline through hole 230 are arranged one by one corresponding to the spline grooves of the first inner spline through hole 130; the second connecting arm 220 is detachably connected between the two first connecting arms 120, and the center axis of the second inner spline through hole 230 and the center axis of the two first inner spline through holes 130 are on the same straight line.

[0037] The spline shaft 300 is provided with an outer spline 310, one side end of the spline shaft 300 is provided with a second connecting flange 320, the outer spline 310 of the spline shaft 300 is spline coupled with the first inner spline through hole 130 and the second inner spline through hole 230, and the second connecting flange 320 is detachably fixedly connected with the first connecting flange 140.

[0038] In one specific embodiment of the utility model, the spline grooves of the first inner spline through hole 130 and the second inner spline through hole 230 are all provided with 12, and the 12 spline grooves are arranged in annular array with intervals. The outer spline 310 of the spline shaft 300 is provided with corresponding 12 spline teeth for spline coupling with the first inner spline through hole 130 and the second inner spline through hole 230. Of course, in other optional embodiments, the number of spline grooves can be 10, 11, 13, etc., and the utility model does not make specific limitation.

[0039] Specifically, the two first connecting arms 120 are arranged with intervals to form a structure similar to a hinged seat, and after the second connecting arm 220 is inserted into the interval between the two first connecting arms 120, the first inner spline through hole 130 is opposite to the second inner spline through hole 230. According to actual installation needs, the second connecting member 200 rotates around the central axis of the second inner spline through hole 230 to change the included angle between the first connecting member 100 and the second connecting member 200, so as to change the included angle between the two floating pipes. After the second connecting member 200 rotates, the spline grooves of the first inner spline through hole 130 and the spline grooves of the second inner spline through hole 230 are still arranged one by one in correspondence. Finally, the spline shaft 300 is inserted, so that the spline teeth of the spline shaft 300 are embedded in the spline grooves of the first inner spline through hole 130 and the spline grooves of the second inner spline through hole 230 one by one. Since the spline shaft 300 is spline coupled with the first inner spline through hole 130 and the second inner spline through hole 230, the freedom of rotation between the first connecting member 100 and the second connecting member 200 is limited, and the angle locking of the first connecting member 100 and the second connecting member 200 is realized. When it is necessary to adjust the angle of the floating pipe, the spline shaft 300 can be taken out to adjust the angle. It is worth noting that the spline shaft 300 is connected and fixed with the first connecting flange 140 on the outside through the second connecting flange 320, so as to constrain the freedom of the spline shaft 300 in the axial direction, thereby avoiding the spline shaft 300 from being taken out of the first inner spline through hole 130 and the second inner spline through hole 230 due to external forces such as waves in water, ensuring the stability of the corner position of the water platform, and avoiding the problem of instability of the water platform caused by wave and current fluctuation.

[0040] The variable-angle floating pipe connecting accessory for the water platform provided by the utility model realizes acute angle, right angle, obtuse angle and horizontal connection of the floating pipe through spline coupling, which can greatly enrich the configuration of the existing water platform frame, such as building a ship-shaped platform and a triangular platform, and the rich configuration can reduce the influence of sea waves on the platform according to local conditions, and further improve the stability of the water platform at the present stage. The floating pipe does not need to be cut and welded, so as to effectively avoid the problem of stress concentration existing in the existing welding. In addition, professional cutting and welding personnel are not needed, so as to reduce the production cost and difficulty.

[0041] Further specifically, one side end of the first floating pipe joint 110 is provided with a first blind hole 111, and the side end of the first floating pipe joint 110 away from the opening of the first blind hole 111 is connected with one end of two first connecting arms 120, and the other end of the two first connecting arms 120 is arranged to extend along the depth direction parallel to the first blind hole 111, and the central axis of the first internal spline through hole 130 is perpendicular to the depth direction of the first blind hole 111; one side end of the second floating pipe joint 210 is provided with a second blind hole 211, and the side end of the second floating pipe joint 210 away from the opening of the second blind hole 211 is connected with one end of the second connecting arm 220; the other end of the second connecting arm 220 is arranged to extend along the depth direction parallel to the second blind hole 211, and the central axis of the second internal spline through hole 230 is perpendicular to the depth direction of the second blind hole 211. More specifically, as shown in Figure 1 the first internal spline through hole 130 is arranged at the side end of the first connecting arm 120 away from the first floating pipe joint 110; and the second internal spline through hole 230 is arranged at the side end of the second connecting arm 220 away from the second floating pipe joint 210. In this way, the angle between the first connecting arm 120 and the second connecting arm 220 corresponds to the angle of the two floating pipes, so as to adjust and change the angle of the floating pipe. Specifically, the first internal spline through hole 130 is arranged at the side of the first connecting arm 120 away from the first pipe sleeve, and the second internal spline through hole 230 is arranged at the side of the second connecting arm 220 away from the second pipe sleeve. In some optional embodiments, one end of the floating pipe is inserted into the first blind hole 111 or the second blind hole 211 in an interference fit manner or a hot melt socket manner, so as to realize the connection between the floating pipe and the first floating pipe joint 110 or the second floating pipe joint 210, and the first blind hole 111 and the second blind hole 211 can avoid water from the other end of the floating pipe joint into the interior of the floating pipe to affect the buoyancy of the floating pipe.

[0042] Of course, in still other optional embodiments, one end of the first connecting arm 120 can be connected to the side wall of the first floating pipe joint 110, and one end of the second connecting arm 220 can be connected to the side wall of the second floating pipe.

[0043] Preferably, as shown in Figure 7 the middle part of the spline shaft 300 is provided with a cavity 330. In this embodiment, by arranging the middle part of the spline shaft 300 with the cavity 330, the spline shaft 300 has better buoyancy, which provides buoyancy support for the corner position, thereby improving the stability of the corner position of the build platform.

[0044] Further, the cavity 330 is provided with a reinforcing rib plate 340. In the embodiment, the reinforcing rib plate 340 is arranged in the cavity 330 to strengthen the strength and rigidity of the spline shaft 300, avoid deformation of the corner position due to large underwater pressure strength, and improve the stability of the corner position of the build platform. In an optional embodiment of the utility model, the cavity 330 is cylindrical, the reinforcing rib plate 340 is provided with two pieces, the two reinforcing ribs are cross-distributed, and the two side edges of the reinforcing rib plate 340 are respectively connected with the inner wall of the cavity 330.

[0045] Specifically, the spline shaft 300 is provided with an end cover 350 at one end away from the second connecting flange 320 to cover the opening of the cavity 330. In the actual application embodiment, the side of the cavity 330 close to the second connecting flange 320 is a closed structure, the end cover 350 is inserted into the opening of the cavity 330 in a hot-melt socket connection manner, so that a closed cavity 330 structure is formed inside, the buoyancy support is provided for the corner position, and the stability of the corner position of the build platform is improved.

[0046] Further optionally, the end of the spline shaft 300 provided with the second connecting flange 320 is provided with an ear 360. In the embodiment, the ear 360 provides a force point for extracting and inserting the spline shaft 300. In addition, when the second connecting flange 320 of the spline shaft 300 is fixedly connected with the first connecting flange 140, the ear 360 can also be used as a lifting point to facilitate hoisting and transferring.

[0047] Further optionally, a reinforcing boss 150 is arranged between the two first connecting arms 120, and the two ends of the reinforcing boss 150 are respectively connected with the corresponding first connecting arms 120. Specifically, in an embodiment of the utility model, the reinforcing boss 150 is protrudingly arranged on the bottom wall of the first floating pipe joint 110 away from the opening of the first blind hole 111, and the two sides of the reinforcing boss 150 are respectively connected with the two first connecting arms 120 to strengthen the two first connecting arms 120 and improve the stability of the corner position.

[0048] Specifically, the first connecting flange 140 and the second connecting flange 320 are connected by a threaded member or a rope. In this way, the first connecting flange 140 and the second connecting flange 320 can be disassembled, so that the spindle can be pulled out of the first inner spline through hole 130 and the second inner spline through hole 230, and the included angle between the first connecting arm 120 and the second connecting arm 220 is adjusted. Specifically, the first connecting flange 140 and the second connecting flange 320 are provided with a corresponding through hole, the threaded member includes a bolt and a nut, the shank of the bolt passes through the through hole of the first connecting flange 140 and the second connecting flange 320 and is threadedly connected with the nut, so that the head of the bolt and the nut clamps the first connecting flange 140 and the second connecting flange 320 on both sides to realize fixed connection. Of course, in other embodiments, the rope is tied after passing through the through hole of the first connecting flange 140 and the second connecting flange 320, and the first connecting flange 140 and the second connecting flange 320 are bound to realize fixed connection.
