Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature container manufacturing, in particular to a pressure container and a support thereof. Background Art

[0002] In today's society, pressure vessels, as commonly used equipment, have been widely used in various production links in petrochemical, metallurgical, shipbuilding and other industries.

[0003] At present, the lifting lugs of pressure vessels are all arranged on the outer shell of the vessel. These standard lifting lugs have simple structures and are easy to manufacture. When the pressure vessel needs to be lifted and transported, a crane or a crane is used to lift and transport the pressure vessel in cooperation with the lifting lugs on the outer shell of the vessel.

[0004] However, for large horizontal containers, due to their heavy weight, large local stress will be generated at the connection between the lifting lug and the container shell during lifting, and even the shell material may be torn. Therefore, it is usually necessary to design a lot of reinforcement structures for the container shell, resulting in a high production cost of the pressure vessel. Moreover, such large horizontal containers are generally used abroad, and the cost of using cranes or hoists in some developed countries is high, which is also a problem that needs to be solved for customers urgently.

[0040] See also Figure 1 As shown, the support of the pressure vessel of the embodiment of the utility model comprises a support body 100, a lifting lug structure 200 and an additional hanging seat 300. The support body 100 is used to support the bottom of the pressure vessel. The support body 100 has two opposite ends, and the two ends of the support body 100 correspond to the two sides of the axial center line of the pressure vessel respectively.

[0041] The ear structure 200 is disposed on the support body 100 and includes a plurality of ear holes 210 symmetrically distributed at both ends of the support body 100. The additional hanger 300 is disposed on the support body 100 and includes a plurality of ear seats 310 symmetrically distributed at both ends of the support body 100.

[0042] like Figure 1As shown, the support body 100 is roughly saddle-shaped. The support body 100 is used to support the bottom of the tank body of the pressure vessel. In the embodiment of the present application, the pressure vessel mainly refers to a large horizontal container. The support is a saddle support. However, the present application is not limited to this. In other embodiments, the pressure vessel can also be a small storage tank structure. The support can also be a support seat of other structural forms.

[0043] The lifting lug structure 200 includes a plurality of lifting lug holes 210, and the plurality of lifting lug holes 210 can be used with equipment such as a crane or a hoist to lift and transport the pressure vessel. The additional lifting seat 300 includes a plurality of lifting lug seats 310, and the plurality of lifting lug seats 310 can be shaft-type lifting lugs or plate-type lifting lugs. The plurality of lifting lug seats 310 can be used with portable lifting equipment such as a jack to lift, unload or transport the pressure vessel.

[0044] In the support of the pressure vessel of the embodiment of the present application, the support body 100 is provided with a lifting ear structure 200 and an additional lifting seat 300, and the lifting ear structure 200 and the additional lifting seat 300 can be used separately to lift the pressure vessel. Therefore, there is no need to design a traditional lifting ear on the container shell, which effectively reduces the cost and meets the customer's needs for lifting in various ways.

[0045] Specifically, considering that the pressure vessel is relatively heavy, a lifting eye hole 210 is provided on the support body 100 to make the lifting reliability higher. The lifting eye hole 210 is directly provided on the support body 100, which has a simple structure and low cost. At the same time, it also avoids the problem of increasing the outer dimensions of the equipment caused by providing the lifting eye structure 200 at other positions, thereby helping to reduce the freight cost.

[0046] By arranging an additional hanging seat 300 on the support body 100, it is possible to meet the needs of customers to directly use equipment such as jacks to lift the additional hanging seat 300 to achieve unloading on site, avoiding the high cost of cranes or hoists, and greatly saving costs; it can also meet the needs of customers who cannot use cranes and hoists on site and can only use small and easy-to-carry equipment such as jacks to lift and transport pressure vessels.

[0047] See also Figure 1 In one embodiment of the present application, the support body 100 includes a support base plate 110, a support pad 120, a support web 130 and a plurality of support ribs 140. The support base plate 110 can be used to be fixed to the foundation. The length direction of the support base plate 110 is perpendicular to the axial direction of the pressure vessel. That is, the two ends of the support body 100 are distributed along the length direction of the support base plate 110.

[0048] The support pad 120 is arranged above the support bottom plate 110 at intervals. The support pad 120 is used to fit the outer peripheral surface of the pressure vessel. For example, the support pad 120 is an arc-shaped pad, which is suitable for wrapping and setting on the outer peripheral surface of the bottom of the tank body of the pressure vessel. For example, the center of the arc-shaped pad can be located on the axial center line of the pressure vessel.

[0049] like Figure 1 As shown in FIG. 1 , in one embodiment, along the direction in which the length of the support base plate 110 extends, the projection length of the support pad 120 on the support base plate 110 is greater than the length of the support base plate 110. Figure 1 From the perspective shown, in the length direction of the support base plate 110, the outer edge size of the support body 100 is that the top length is greater than the bottom length. The longer top length of the support body 100 can increase the contact area between the support body 100 and the pressure vessel, and improve the support stability of the pressure vessel. The shorter bottom length of the support body 100 can save materials to a certain extent and reduce the production cost while ensuring that the overall support strength of the support is sufficient, and at the same time, space can be left to set up the additional hanger 300.

[0050] In the embodiment of the present application, the support web 130 is connected between the support base plate 110 and the support pad 120. Figure 1 As shown, in one embodiment, along the direction in which the length of the support base plate 110 extends, the projection length of the support web 130 on the support base plate 110 is greater than the projection length of the support pad 120 on the support base plate 110. That is, in the length direction of the support base plate 110, the support web 130 is arranged to protrude outward relative to the support pad 120. The outer edge size of the support body 100 is the largest at the support web 130. Therefore, the support web 130 can protect the two ends of the support pad 120 from being easily impacted, thereby protecting the two sides of the pressure vessel on the support pad 120 from being easily impacted.

[0051] It should be noted that, along the direction of the length extension of the support base plate 110, the outer edge size of the support body 100 as a whole needs to be controlled within the required range of the equipment transportation size. In the embodiment of the present application, in the length direction of the support base plate 110, the outer edge size of the support body 100 is the largest at the support web 130. Therefore, when designing the support body 100, it is only necessary to control the length size of the support web 130 within the required range of the equipment transportation size, so that the overall transportation size of the equipment can meet the requirements.

[0052] like Figure 1As shown, a plurality of lifting ear holes 210 may be provided on the support web 130. Specifically, the plurality of lifting ear holes 210 are respectively provided at both ends of the support web 130. For example, the number of the lifting ear holes 210 may be two, and the two lifting ear holes 210 are symmetrically provided at both ends of the support web 130. In this embodiment, the lifting ear holes 210 are provided at both ends of the support web 130, which can facilitate the connection between the lifting ear holes 210 and the sling.

[0053] See also Figure 2 As shown, in one embodiment, the ear structure 200 further includes an ear reinforcement plate 230, which is arranged on at least one side surface of the support web 130 at each ear hole 210. The ear reinforcement plate 230 is provided with through holes corresponding to the ear holes 210. In this embodiment, by providing the ear reinforcement plate 230, the structural strength of the ear hole 210 of the support web 130 can be increased, and the plate body tearing caused by excessive stress at the lifting position can be avoided.

[0054] like Figure 2 As shown, there may be two lifting ear reinforcement plates 230, and the two lifting ear reinforcement plates 230 may be disposed on both side surfaces of the support web 130. Each lifting ear reinforcement plate 230 may be welded and fixed to the surface of the support web 130.

[0055] In other embodiments, there may be one lifting eye reinforcement plate 230 , which may be disposed on any side surface of the support web 130 .

[0056] See also Figure 3 and Figure 4 In one embodiment, the ear structure 200 further includes a reinforcing tube 220 disposed in the ear hole 210, and the outer circumferential surface of the reinforcing tube 220 is arranged to fit the inner wall surface of the ear hole 210. The reinforcing tube 220 can be welded and fixed to the ear hole 210. By providing the reinforcing tube 220, the structural strength of the circumferential side wall of the ear hole 210 can be increased, and the occurrence of tearing of the plate body due to excessive stress at the lifting position can be avoided.

[0057] like Figure 4 As shown, when both side surfaces of the support web 130 are provided with lifting ear reinforcement plates 230, the reinforcement tube 220 extends into the through hole of the lifting ear reinforcement plates 230. For example, the end surface of the reinforcement tube 220 can be flush with the surface of each lifting ear reinforcement plate 230. By extending the reinforcement tube 220 into the through hole, the reinforcement tube 220 plays an integral reinforcement role on the side wall around the lifting ear hole 210 and the side wall around the through hole, thereby further enhancing the structural strength at the lifting ear hole 210, which is conducive to improving the hoisting stability of the equipment.

[0058] See also Figure 1In the embodiment of the present application, a plurality of support ribs 140 are arranged between the support base plate 110 and the support pad 120 at intervals, and each support rib 140 is vertically connected to the support web 130 .

[0059] like Figure 1 As shown, among the plurality of support ribs 140, two of the support ribs 140 are respectively connected at the two ends of the support base plate 110. A plurality of lug seats 310 may be arranged on the two support ribs 140. The number of the lug seats 310 may be two, and the two lug seats 310 are symmetrically arranged on the two support ribs 140.

[0060] like Figure 1 As shown, the support rib plate 140 located at the end of the support base plate 110 has its top end connected to the end of the support pad 120, and its bottom end connected to the end of the support base plate 110. Since the support pad 120 is longer than the support base plate 110, the support rib plate 140 located at the end of the support base plate 110 is arranged obliquely between the support base plate 110 and the support pad 120. For example, when the support pad 120 is an arc-shaped pad, the support rib plate 140 located at the end of the support base plate 110 can be arranged along the tangent direction of the support pad 120.

[0061] like Figure 1 As shown, except for the two support ribs 140 disposed at both ends of the support base plate 110, the remaining plurality of support ribs 140 may be disposed perpendicular to the support base plate 110. And the plurality of support ribs 140 may be disposed between the support base plate 110 and the support pad 120 at equal intervals.

[0062] like Figure 1 As shown, a triangular space can be formed between the support rib plate 140 and the support web plate 130 at the end of the support bottom plate 110, and the triangular space can be used as the installation space of the ear seat 310. The ear seat 310 can make full use of the installation space and be connected to the support body 100.

[0063] See also Figure 1 In one embodiment, along the direction of the length extension of the support base plate 110, the projection of the lug seat 310 on the support base plate 110 does not exceed the upper projection of the support web 130 on the support base plate 110. In this embodiment, when the lug seat 310 is installed on the support body 100, the outer edge of the lug seat 310 does not exceed the outer edge of the end of the support web 130. Therefore, the provision of the additional hanging seat 300 does not increase the length dimension of the support body 100, ensuring that the length dimension of the support body 100 can be controlled within the required range of the transportation dimension of the equipment.

[0064] See also Figure 1 and Figure 5As shown, in one embodiment, the ear seat 310 includes a mounting plate 311 and an ear 312, the ear 312 is protrudingly arranged on the surface of the mounting plate 311, and the mounting plate 311 is fixedly mounted on one side of the support rib plate 140. The ear 312 can be welded to the mounting plate 311.

[0065] For ease of description, it is now stipulated that the side of the support rib plate 140 located at the end of the support base plate 110 facing the middle of the support base plate 110 is defined as the inner side, and the ear seat 310 is installed on the outer side of the support rib plate 140.

[0066] For example, the lifting lug 312 may be a plate type lifting lug. Figure 6 As shown, the lifting lug 312 may be an I-shaped lifting lug formed by splicing a plurality of plates. Alternatively, in other embodiments, the lifting lug 312 may also be an axial lifting lug.

[0067] See also Figure 1 and Figure 6 As shown, in one embodiment, each ear seat 310 is detachably connected to the support body 100. Specifically, each ear seat 310 is detachably connected to the support rib plate 140 located at the end of the support bottom plate 110.

[0068] like Figure 6 As shown, the mounting plate 311 may be provided with a plurality of connection holes 313. The support rib plate 140 may be provided with fixing holes corresponding to the connection holes 313. By using fasteners such as bolts to penetrate through the connection holes 313 and the corresponding fixing holes in sequence, the hanging ear seat 310 can be detachably fixed to the support rib plate 140.

[0069] By making the lifting lug seat 310 and the support body 100 detachable, the lifting lug seat 310 can be removed in some cases where the additional lifting seat 300 is not needed. For example, when hoisting a storage tank, if the bottom size is limited, the lifting lug seats 310 of the additional hanging seat 300 can be temporarily removed to make the overall size of the equipment meet the hoisting and transportation requirements.

[0070] See also Figure 1 In one embodiment, the additional hanger 300 further includes an ear seat reinforcement plate 320, which is arranged on the other side of the support rib plate 140 in correspondence with the mounting plate 311. The ear seat reinforcement plate 320 is fixedly connected to the outer side of the support rib plate 140 at the end of the support base plate 110. By providing the ear seat reinforcement plate 320, the structural strength of the connection between the hanging ear seat 310 and the support rib plate 140 is increased, and the plate body is prevented from being torn due to excessive local stress at the connection when a force is applied to the hanging ear seat 310.

[0071] like Figure 1As shown, the ear seat reinforcement plate 320 can be detachably fixed to the support rib plate 140. For example, through holes can be provided on the ear seat reinforcement plate 320 corresponding to each fixing hole. When installing the ear seat 310, the bolts are passed through the connection hole 313, the fixing hole and the through hole in sequence, so that the ear seat 310 and the ear seat reinforcement plate 320 can be detachably fixed to the support rib plate 140.

[0072] The support for the pressure vessel of the embodiment of the utility model can be used for large horizontal containers. The customer can use a crane or a crane to lift the equipment by means of the lifting ear holes 210 on the support body 100. The customer can also use the additional lifting seat 300 on the support body 100 to lift the equipment with a portable tool such as a jack for unloading or transportation.

[0073] In addition, when hoisting the equipment, if the bottom size is limited, the additional suspension base 300 can be temporarily removed to make the equipment meet the transportation requirements.

[0074] The support for the pressure vessel of the embodiment of the utility model has low cost and can meet the needs of customers for lifting in various ways.

[0075] See also Figure 1 As shown, an embodiment of the utility model further provides a pressure vessel, comprising a tank body 10 and a support for the pressure vessel as described in any of the above embodiments.

[0076] The support body 100 is supported and arranged at the bottom of the tank body 10. Specifically, the support pad 120 of the support body 100 is arranged in contact with the outer peripheral surface of the bottom of the tank body 10. The support base plate 110 of the support body 100 can be placed on the foundation and fixed by anchor bolts.

[0077] Since the support body 100 is provided with a lifting ear structure 200 and an additional lifting seat 300, the lifting ear structure 200 and the additional lifting seat 300 can be used for lifting and transportation in different scenarios, respectively. Therefore, the pressure vessel of the present application is more convenient to use and can meet the needs of customers for lifting and transportation of pressure vessels in various ways.

[0078] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0079] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
