Description

Technical Field

[0001] The present application relates to the technical field of horizontal container installation, and in particular to a movable end base of a horizontal container. Background Art

[0002] Horizontal container is a common equipment in petrochemical plants. The equipment is generally installed on the ground or floor and uses a pier foundation as support. Due to the large thermal expansion and contraction of horizontal containers, their foundations are mostly composed of a fixed seat and a movable seat. Article 6.1.3 of the current "Petrochemical Cooling Equipment and Container Foundation Design Code" SH / T3058-2016 stipulates: When the medium temperature of the container is greater than 80°C, the influence of friction or elastic force caused by the temperature change of the medium should be considered; the standard value of the friction should be calculated according to the following provisions: F tk =μ(G BK +G jk ). Where μ represents the friction coefficient between the container base and the foundation, G BK , G jk They represent the standard values ​​of the permanent load of the container and the medium load in the container under normal operating conditions. It can be seen from the formula that, when the container and the medium are determined, the friction force generated by the container on the top surface of the foundation due to thermal expansion increases with the increase of the friction coefficient, and decreases with the decrease of the friction coefficient.

[0003] At present, the common practice of using movable end foundation is to support the horizontal container support by embedding the movable end pier of the steel plate on the top surface. The specification stipulates that when the support surface is a steel plate, the friction coefficient μ is 0.3. It is found in the project that when the container and the medium are heavy, such as the electric desalination tank, the total weight of the equipment is more than 1000t, the friction force generated by the temperature rise deformation will form a thrust of more than 100t on the foundation, often causing the foundation to crack and deform, which brings safety hazards to the normal use of the equipment. Summary of the invention

[0004] The present application provides a horizontal container movable end foundation seat, which adds a special graphene layer between the container base and the foundation steel pad, which not only reduces the friction but also does not increase the construction difficulty too much. According to calculations, the foundation thrust can be reduced by more than 2 / 3, which not only increases the foundation reliability but also reduces the amount of foundation steel bars and concrete, saving foundation costs. The construction is also relatively simple, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a base seat for the movable end of a horizontal container, comprising a horizontal container, a foundation and a pressure plate; an embedded steel plate is installed on the upper surface of the foundation, a stud one is provided on the embedded steel plate, a connecting plate is installed on the stud one, and a graphene coating is provided between the lower surface of the connecting plate and the upper surface of the embedded steel plate.

[0006] A saddle is provided on the upper surface of the connecting plate, and the saddle includes a support frame. An arc-shaped support plate is provided on the upper surface of the support frame. Ear plates are provided at the outer side edges of the pressure plate and the arc-shaped support plate. The ear plates symmetrically arranged up and down are connected together by two studs.

[0007] Preferably, a pre-load nut and a drag-reducing gasket are connected to the stud.

[0008] Preferably, the lower surface of the drag reducing gasket is evenly distributed with spherical protrusions.

[0009] Preferably, a strip hole is provided on the upper surface of the connecting plate, and a stud is arranged through the strip hole.

[0010] Preferably, a clamping nut is provided on the second stud, a spring is sleeved on the second stud, and the spring is arranged on the lower surface of the clamping nut.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] 1. A special graphene layer is added between the container base and the foundation steel plate. Graphene is a new type of material with excellent thermal stability, chemical stability and strength far higher than steel. More importantly, compared with other materials, graphene has an extremely low friction coefficient and is a very excellent lubricating material. This method reduces friction without increasing the difficulty of construction. According to calculations, the foundation thrust can be reduced by more than 2 / 3, which increases the reliability of the foundation, reduces the amount of foundation steel bars and concrete, saves foundation costs, and is relatively simple to construct.

[0013] 2. When the horizontal container is heated or pre-cooled and deformed, the horizontal container pushes the connecting plate to slide on the upper surface of the embedded steel plate along the direction of the strip hole. Since the upper surface of the embedded steel plate is covered with a 0.1 mm thick graphene coating, the foundation is subjected to less thrust, which can effectively protect the foundation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 this field without creative work are within the scope of protection of this application.

[0021] In the description of this application, when a feature is referred to as being "set", "fixed" or "connected" to another feature, it may be directly set, fixed or connected to the other feature, or indirectly set, fixed or connected to the other feature.

[0022] See also Figure 1-5 The present application provides the following technical solutions: a horizontal container movable end base, comprising a horizontal container 1, a foundation 3 and a pressure plate 21; an embedded steel plate 9 is installed on the upper surface of the foundation 3, a stud 6 is provided on the embedded steel plate 9, a connecting plate 8 is installed on the stud 6, and a graphene coating 5 is provided between the lower surface of the connecting plate 8 and the upper surface of the embedded steel plate 9.

[0023] Specifically, a graphene coating 5 is added between the embedded steel plate 9 and the connecting plate 8. Graphene is a new type of material with excellent thermal stability, chemical stability and strength far higher than that of steel. More importantly, compared with other materials, the friction coefficient of graphene is extremely low (friction coefficient μ≤0.1), and it is a very excellent lubricating material. This method reduces friction without increasing the difficulty of construction too much. According to calculations, the foundation thrust can be reduced by more than 2 / 3, which increases the reliability of the foundation, reduces the amount of foundation steel bars and concrete, saves foundation costs, and is relatively simple to construct.

[0024] More specifically, the thickness of the graphene coating 5 is 0.01 mm.

[0025] The upper surface of the connecting plate 8 is provided with a saddle 2, and the saddle 2 includes a support frame 26. The upper surface of the support frame 26 is provided with an arc-shaped support plate 25. The outer side edges of the pressure plate 21 and the arc-shaped support plate 25 are both provided with ear plates, and the ear plates symmetrically arranged above and below are connected together by studs 22.

[0026] Specifically, the saddle 2 is fixed together with the horizontal container 1, and the arc-shaped support plate 25 is close to the outer surface of the horizontal container 1. At the same time, the stud 22 can be adjusted according to the specific usage scenario to change the pressure applied by the pressure plate 21 to the horizontal container 1, which can further improve the stability of the connection.

[0027] Furthermore, the stud 1 6 is connected with a pre-loaded nut 7 and a drag-reducing gasket 4 .

[0028] Specifically, the pressure applied by the pre-load nut 7 should not be too large to prevent the position of the connecting plate 8 from being locked.

[0029] Furthermore, the lower surface of the drag reducing gasket 4 is evenly distributed with spherical protrusions.

[0030] Specifically, the provision of the spherical protrusions can effectively reduce the contact area, thereby reducing the friction force.

[0031] Furthermore, a strip hole 81 is provided on the upper surface of the connecting plate 8 , and the stud 1 6 is arranged through the strip hole 81 .

[0032] Specifically, the arrangement of the strip-shaped hole 81 allows the connecting plate 8 to have a certain displacement relative to the stud 1 6 .

[0033] Furthermore, a clamping nut 23 is provided on the second stud 22 , and a spring 24 is sleeved on the second stud 22 . The spring 24 is arranged on the lower surface of the clamping nut 23 .

[0034] Specifically, when the horizontal container 1 is deformed during production, the pressing plate 21 can be pushed upward. Due to the presence of the spring 24 , the pressing plate 21 can always be pressed tightly against the outer surface of the horizontal container 1 .

[0035] During use: When the horizontal container 1 is heated or pre-cooled and deformed, the horizontal container 1 pushes the connecting plate 8 to slide on the upper surface of the embedded steel plate 9 along the direction of the strip hole 81. Since the upper surface of the embedded steel plate 9 is covered with a 0.1 mm thick graphene coating, the foundation 3 is subjected to less thrust, which can effectively protect the foundation 1.

[0036] When the horizontal container 1 is deformed due to collision, the spring 23 will be squeezed. The synchronized spring 23 can effectively ensure that the pressure plate 21 and the arc-shaped support plate 25 can be closely attached to the outer side surface of the horizontal container 1 .

[0037] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
