Description

Technical Field

[0001] The present application belongs to the field of ship engineering technology, and specifically relates to a guide support device. Background Art

[0002] Valves are commonly used in pipe systems on ships. For emergency operation needs, the valve stem needs to be extended and passed through the top deck. After the valve stem passes through the top deck, the crew can operate the valve disc installed at the end of the valve stem to switch the valve. In an emergency, the crew can manually close or open the valve without entering the cabin where the valve is located. When the valve stem needs to be extended a long distance, when the crew controls the movement of the valve stem, the valve stem is prone to shaking and interfering with the ship's equipment.

[0003] Currently, a support block is provided to support the valve stem, but the supporting effect on the valve stem is limited, and the valve stem is still prone to interference and shaking, affecting the normal operation of the valve. Summary of the invention

[0004] The present application provides a guide support device, which aims to solve the problem that the valve stem is extended too long and affects the normal operation of the valve to at least a certain extent.

[0005] In a first aspect of the present application, a guide support device is provided, which is used to guide and support a valve stem extending to a ship deck, comprising:

[0006] A supporting structure and a pad, wherein the supporting structure is connected to the deck through the pad, and the supporting structure is provided with a mounting hole;

[0007] A guide sleeve is connected to the support structure and is interference-fitted with the assembly hole, and an inner hole of the guide sleeve is used for clearance fit with the valve stem.

[0008] In some embodiments, at least one end of the guide sleeve is provided with a chamfer.

[0009] In some embodiments, the surface accuracy of the inner hole is greater than the surface accuracy of the valve stem.

[0010] In some embodiments, at least one end of the guide sleeve is provided with an annular flange, and the annular flange abuts against the support structure.

[0011] In some embodiments, the support structure comprises:

[0012] a bottom plate connected to the deck via the spacers;

[0014] In some embodiments, the support structure further comprises:

[0015] At least two ribs are respectively connected to the bottom plate and the bearing ring, and the connection between the ribs, the bottom plate and the bearing ring is rounded.

[0016] In some embodiments, the axial length of the bearing ring is greater than the inner diameter of the bearing ring.

[0017] In some embodiments, a diameter of the inner hole is larger than an axial length of the support structure along the assembly hole.

[0018] In some embodiments, the guide support device may further include at least one cushion block.

[0019] In some embodiments, the guide support device further comprises:

[0020] The fasteners are inserted and connected in sequence to the supporting structure, the cushion block and the deck, and the supporting structure and the cushion block are provided with connecting holes corresponding to the fasteners.

[0030] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] Figure 1 FIG. 1 shows a schematic diagram of the use state of the guide support device in one or more embodiments of the present application, with reference to FIG. Figure 1 In a first aspect of the present application, a guide support device is provided, which is used to guide and support a valve stem 20 extending to a ship deck 10, comprising:

[0032] The supporting structure 1 and the pad 2 are connected to the deck via the pad 2 , and the supporting structure 1 is provided with an assembly hole 11 .

[0033] The guide sleeve 3 is connected to the support structure 1 and has an interference fit with the assembly hole 11 . The inner hole of the guide sleeve 3 is used for clearance fit with the valve stem 20 .

[0034] The support structure 1 of the guide support device is connected to the deck through the cushion block 2. The support structure 1 and the cushion block 2 can adjust the height relative to the deck to provide a height-appropriate support for the valve stem 20. The support structure 1 is provided with an assembly hole 11, and the assembly hole 11 is interference-fitted with the guide sleeve 3. The inner hole of the guide sleeve 3 is clearance-fitted with the valve stem 20, so that the guide sleeve 3 can be sleeved on the valve stem 20 and then uniformly assembled on the support structure 1. It is convenient to adjust the position of the guide support device relative to the valve stem 20 and the ship deck 10, and it can also ensure that the guide sleeve 3 is sleeved on the valve stem 20, and then the valve stem 20 is stably guided and supported through the inner hole of the guide sleeve 3. The hole-shaped structure can largely limit the radial degree of freedom of the valve stem 20 and stably support the valve stem 20. The valve stem 20 extending to the ship deck 10 can also be guided and supported to reduce the shaking of the valve stem 20 and the possible interference with other ship equipment. To a certain extent, the problem of the valve stem 20 extending too long to affect the normal operation of the valve is solved.

[0035] It should be noted that Figure 1 The presence of a ship deck 10 connected to the pad 2 is shown in FIG. Figure 1 The ship cabin where the valve stem 20 is located is omitted, and both ends of the valve stem 20 can be connected to the valve body and the operating rod respectively, and the inner hole of the guide sleeve 3 is a hole formed by the peripheral wall with a smaller diameter of the guide sleeve 3. This application does not limit this.

[0036] In some embodiments, at least one end of the guide sleeve 3 is provided with a chamfer 31. The chamfer 31 facilitates the matching between the valve stem 20 and the guide sleeve 3, and also facilitates the disassembly and assembly between the valve stem 20 and the guide sleeve 3.

[0037] In some embodiments, the surface accuracy of the inner hole is greater than the surface accuracy of the valve stem 20. The friction resistance between the guide sleeve 3 and the valve stem 20 is reduced, and the working efficiency of the valve structure where the valve stem 20 is located is improved.

[0038] In some embodiments, at least one end of the guide sleeve 3 is provided with an annular flange 32, and the annular flange 32 abuts against the support structure 1. The annular flange 32 and the support structure 1 can play an effective supporting role, facilitating the assembly support between the guide sleeve 3 and the support structure 1.

[0039] In some embodiments, the annular flange 32 on the guide sleeve 3 may be in the shape of an annular plate or other cross-sectional shapes, which is not limited in the present application.

[0040] In some embodiments, the chamfers 31 may not be provided at both ends of the guide sleeve 3, the surface accuracy of the inner hole may be equal to or less than the surface accuracy of the valve stem 20, and the guide sleeve 3 may not be provided with the annular flange 32, and it can also play a good guiding and supporting role for the valve stem 20. The present application does not impose any restrictions on this.

[0041] In some embodiments, the wall thickness of the guide sleeve 3 may be about 5 mm, and Q235B steel or equivalent material may be used, and the linear dimension tolerance of the machined surface is in accordance with the m grade of GB / T1804-2000, which is convenient for preparation and acquisition.

[0042] In some embodiments, the support structure 1 comprises:

[0043] The bottom plate 12 is connected to the deck through the spacers 2.

[0044] The bearing ring 13 is connected to the base plate 12 , and the bearing ring 13 is configured as the assembly hole 11 .

[0045] The supporting structure 1 includes a base plate 12 and a bearing ring 13 which are connected to each other. The supporting structure 1 has a simple structure and is easy to prepare and connect with the valve stem 20 .

[0046] In some embodiments, the support structure 1 further includes at least two ribs 14. The at least two ribs 14 are respectively connected to the bottom plate 12 and the bearing ring 13, and the connection between the ribs 14 and the bottom plate 12 and the bearing ring 13 is rounded.

[0047] The strength of the supporting structure 1 can be increased and the implementation is also convenient.

[0048] In some embodiments, at least two ribs 14 may surround the bearing ring 13 and connect the bearing ring 13 and the bottom plate 12 , thereby effectively increasing the overall strength of the support structure 1 .

[0049] In some embodiments, the axial length of the bearing ring 13 is greater than the inner diameter of the bearing ring 13. This ensures the supporting effect on the valve stem 20 while reducing the manufacturing cost.

[0050] In some embodiments, the diameter of the inner hole is larger than the axial length of the support structure 1 along the assembly hole 11. The support effect on the valve stem 20 is better.

[0051] In some embodiments, the guide support device may further include at least one cushion block 2. The at least one cushion block 2 may effectively adjust the support position and effect of the guide support device as a whole on the valve stem 20.

[0052] In some embodiments, the thickness of at least one spacer block 2 may be inconsistent, so as to facilitate height adjustment.

[0053] In some embodiments, the length and width of the pad 2 may be consistent with the length and width of the base plate 12. In this embodiment, the thickness value may be 130 mm x 100 mm. If the thickness value is not enough, a thin copper gasket may be added. If the pad 2 is too thick, it may be appropriately thinned. This application does not limit this.

[0054] In some embodiments, the guide sleeve 3 can be pressed into the bearing ring 13, and the inner hole of the guide sleeve 3 can be processed according to the diameter of the valve stem 20. After processing, the valve stem 20 passes through the bearing ring 13 and the guide sleeve 3, and the guide support device is fixed to the nearby hull structure through the bolt fastener 4. The distance between the assembly and the hull structure is measured, and the adjustment pad 2 is processed according to the value. After the adjustment pad 2 is processed, it is drilled with the valve stem 20 support and fastened with bolts. It is beneficial to improve the guiding and supporting effect of the valve stem 20.

[0055] In some embodiments, the guide support device further comprises: a fastener 4, which is sequentially inserted into and connected to the support structure 1, the cushion block 2 and the deck, and the support structure 1 and the cushion block 2 are provided with connection holes corresponding to the fastener 4. This facilitates adjusting the position of the guide support device.
