Technical Field

[0001] The utility model relates to the technical field of gas utilization, in particular to a lifting structure of a gas supply terminal. Background Art

[0002] Gases are used in many scenarios in production and life, such as oxygen, air, nitrogen and other gases. Therefore, the reasonable installation of gas supply terminals has become a research focus.

[0003] For gas-using equipment with a platform, the space above the platform is usually used as an activity and operation space, and the space below the platform is used as a storage and equipment installation space. Since the space above the platform is limited, reasonable planning is required during the design. However, since gas-using equipment is usually used on the platform, for ease of use, the gas supply terminal is usually installed directly on the platform, resulting in it occupying more space above the platform. Especially for comprehensive gas-using equipment, it is necessary to arrange multiple gas supply terminals on the platform, resulting in a serious waste of space above the platform, which is not conducive to the use of the space above the platform when gas is not in use. In addition, although there are some solutions to install the gas supply terminal below the platform, at this time, although it can avoid occupying the space above the platform and facilitate the use of the space above the platform, when gas is needed in the space above the platform in the future, it is necessary to connect the pipeline to the bottom of the platform, which is inconvenient to use.

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 4 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0027] Figure 1 A structural diagram of a lifting structure of a gas supply terminal according to an embodiment of the present invention from one perspective; Figure 2 This is a structural diagram from another perspective of an embodiment of a lifting structure of a gas supply terminal of the present utility model. Figure 1and Figure 2 As shown, the lifting structure of the gas supply terminal provided in this embodiment is arranged between the platform 1 and the gas supply terminal 2. At this time, a lifting hole 11 is opened on the platform 1, and the upper space and the lower space of the platform 1 are connected through the lifting hole 11 to lift the gas supply terminal 2 onto the platform 1 or retract it to the bottom of the platform 1. Figure 3 This is a diagram showing the state of a lifting structure of a gas supply terminal of the utility model when it is extended; Figure 4 This is a diagram showing the state of the lifting structure of a gas supply terminal of the present invention when it is retracted. Figure 3 and Figure 4 As shown, when the gas supply terminal 2 is extended onto the platform 1, it is convenient for users to use gas on the platform 1, improving the convenience of use. When the gas supply terminal 2 is retracted below the platform 1, it can be temporarily hidden, thereby avoiding occupying the space above the platform 1 and facilitating the utilization of the space above the platform 1. For example, when the platform 1 is the deck of a ship, the gas supply terminal 2 can be raised above the deck when gas is needed to facilitate gas supply. When the gas supply terminal 2 is retracted below the deck, it can avoid occupying the space above the deck when gas is not needed.

[0028] Specifically, the lifting structure includes a lifting frame 3, a guide assembly 4, and a lifting drive assembly 5. During installation, the lifting frame 3 is mounted in the lower space of the platform 1, directly below the lifting hole 11. It serves as a mounting support for the subsequent guide assembly 4 and lifting drive assembly 5, and also provides a concealed space for the gas supply terminal 2. The upper end of the lifting frame 3 is fixedly mounted on the platform 1, ensuring stable installation of the lifting frame 3. Furthermore, the lifting frame 3 itself has a mounting cavity that is vertically connected to the corresponding lifting hole 11, facilitating subsequent passage of the gas supply terminal 2 through the lifting hole 11, thereby concealing it within the mounting cavity. Furthermore, the mounting cavity of the lifting frame 3 is provided with a vertically movable lifting plate 21. When the gas supply terminal 2 is mounted on the lifting plate 21, the gas supply terminal 2 is lifted and lowered within the mounting cavity of the lifting frame 3, thereby meeting the requirements of raising the gas supply terminal 2 to the platform 1 or retrieving it from the platform 1.

[0029] Furthermore, the guide assembly 4 is disposed on the lifting frame 3, and in this case, the guide assembly 4 further comprises a guide rail 41 and a roller 42. During installation, the guide rail 41 is mounted on the lifting frame 3 in a vertical direction, ensuring stable vertical installation of the guide rail 41. Simultaneously, the roller 42 is mounted on the lifting platform 21, and the roller 42 can slide along the guide rail 41. This allows the lifting platform 21 to be guided by the sliding of the roller 42 relative to the guide rail 41 when it is subsequently raised or lowered on the lifting frame 3 under the action of the lifting drive assembly 5. This maintains the stability of the lifting platform 21 during its raising or lowering, thereby improving the stability of the gas supply terminal 2 during the raising or lowering process and ensuring smooth raising or lowering of the gas supply terminal 2.

[0030] Furthermore, the lift drive assembly 5 is installed on the lifting frame 3 and below the lifting plate 21, facilitating the subsequent connection between the lift drive assembly 5 and the lifting plate 21. After installation, the lift drive assembly 5 is configured to move vertically, and the upper end of the lift drive assembly 5 is connected to the lifting plate 21. This allows the lift drive assembly 5 to move the lifting plate 21 upward and downward within the lifting frame 3, thereby lifting or retracting the gas supply terminal 2 and serving as a power source for moving the gas supply terminal 2.

[0031] More specifically, the guide assembly 4 is provided with four guide rails 41. At this time, the four guide rails 41 are distributed in a rectangular shape and arranged around the outside of the lifting plate 21, so that guide rails 41 are provided on all four sides of the lifting plate 21, and each guide rail 41 corresponds to a roller 42, and the rollers 42 are respectively installed on the lifting plate 21, so that there are corresponding guide structures for guidance in the four directions around the lifting plate 21, which further improves the stability of the gas supply terminal 2 during lifting and lowering, and the structural design is more reasonable.

[0032] More specifically, the cross-section of each guide rail 41 in the guide assembly 4 is arranged in a "U" shape. In this case, the opening of the guide rail 41 is a guide groove 411. That is, the two sides of the guide rail 41 are bent toward the same side to form a rib, and the space between the two ribs is set as the guide groove 411. The corresponding roller 42 is installed in the guide groove 411. As the roller 42 moves within the corresponding guide groove 411, the guide groove 411 can guide the movement of the roller 42, thereby limiting the movement direction of the roller 42 and providing stable guidance for the lifting and lowering of the gas supply terminal 2. In addition, the opening of each guide groove 411 is arranged to face one side of the lifting carrier 21, so that the roller 42 installed on the lifting carrier 21 can smoothly extend into the corresponding guide groove 411, resulting in a simpler structure and lower manufacturing costs.

[0033] More specifically, when the roller 42 is engaged with the corresponding guide groove 411, the side of the roller 42 extends into the guide groove 411, facilitating the cooperation and guidance of the roller 42 and the guide groove 411. Preferably, after the side of the roller 42 is extended into the guide groove 411, a gap is provided between the two sides of the roller 42 and the two side walls of the corresponding guide groove 411. That is, the preset gap provides a certain amount of deflection margin for the movement of the roller 42 in the guide groove 411. This ensures that even if the lifting frame 3, guide rail 41, and other structures deform after long-term use, thereby affecting the trajectory of the roller 42 when the air supply terminal 2 is raised or lowered, the roller 42 can still meet the requirements of cooperation and guidance with the guide groove 411, thereby enhancing structural flexibility and adaptability.

[0034] More specifically, each roller 42 includes a wheel body 421 and a mounting seat 422. During installation, the upper end of the mounting seat 422 is mounted on the side or bottom surface of the lifting platform 21, thereby connecting the mounting seat 422 to the lifting platform 21. At the same time, the lower end of the mounting seat 422 is extended downward, preventing the mounting seat 422 from occupying the space on the lifting platform 21 used to arrange the gas supply terminal 2, thereby making more reasonable use of space. In addition, clamping plates are provided on both sides of the lower end of the mounting seat 422. In this case, there is a gap between the two clamping plates. The wheel body 421 is arranged between the two clamping plates and is rotatably mounted on the two clamping plates via a rotating shaft. This provides support on both sides of the wheel body 421, maintaining the force balance after the wheel body 421 is installed, thereby ensuring the stability of the wheel body 421 when moving within the guide groove 411, and making the structural design more reasonable.

[0035] More specifically, a cover plate 12 is provided on the platform 1 at the lifting hole 11. At this time, the cover plate 12 can be a flip cover or a detachable cover plate 12, so that when the gas supply terminal 2 is recovered under the platform 1, the lifting hole 11 on the platform 1 can be covered by the cover plate 12, thereby ensuring the flatness of the upper surface of the platform 1 and facilitating the utilization of the upper space of the platform 1.

[0036] More specifically, the lifting carrier plate 21 that performs lifting movement in the lifting frame 3 can directly use the base plate of the gas supply terminal 2, that is, the lifting drive component 5 and the roller 42 in the guide component 4 are directly installed on the base plate of the gas supply terminal 2, reducing the intermediate transfer structure, reducing the manufacturing cost, and also reducing the workload of the lifting drive component 5.

[0037] More specifically, the air inlet of the air supply terminal 2 is set at the bottom. At this time, the air inlet of the air supply terminal 2 is connected to the air inlet pipe 6, and the air storage equipment is connected through the air inlet pipe 6. During installation, one end of the air inlet pipe 6 is located in the installation cavity and is a hose, which realizes the arrangement of the air inlet pipe 6 in the installation cavity of the lifting frame 3, meets the connection requirements of the air supply terminal 2, and can also adapt to the lifting movement of the air supply terminal 2 through its own deformation, and the structural design is more reasonable.

[0038] More specifically, the lifting drive assembly 5 includes a telescopic rod 51 and a driver 52. At this time, the telescopic rod 51 is arranged in the installation cavity and the top end is connected to the lifting carrier 21 to realize the direct connection between the lifting driver 52 assembly and the lifting carrier 21. At the same time, the driver 52 is arranged outside the installation cavity and is connected to the telescopic rod 51 power. Preferably, a reducer is arranged between the driver 52 and the telescopic rod 51, and the reducer is located at the cavity wall of the installation cavity to connect the telescopic rod 51 and the driver 52 located on the inside and outside of the installation cavity respectively, which can not only meet the power transmission requirements, but also isolate the driver 52 outside the installation cavity, so that even if the driver 52 uses electrical equipment such as a motor, the operation of the driver 52 will not interfere with the gas supply terminal 2, thereby avoiding the safety hazards when flammable and explosive gases exist in the gas supply terminal 2, and the safety protection is higher. It is worth noting that the lifting drive assembly 5 including the telescopic rod 51 and the driver 52 includes but is not limited to conventional electric push rods on the market, which can meet the linear telescopic movement. There are many structures on the market that can realize this process. In this embodiment, one of them can be selected and used directly. Therefore, its specific structure will not be repeated here.

[0039] The lifting structure of the gas supply terminal provided in this embodiment includes a lifting frame 3, a guide assembly 4 and a lifting drive assembly 5; by arranging the lifting frame 3 with an installation cavity under the platform 1 with a lifting hole 11, and the upper end of the lifting frame 3 is installed on the platform 1 and the installation cavity is connected to the lifting hole 11, the guide assembly 4 and the lifting drive assembly 5 are both provided with an installation cavity, the gas supply terminal 2 is installed on the lifting drive 52 assembly and cooperates with the lifting frame 3 through the guide assembly 4, so that the gas supply terminal 2 can stably rise to the platform 1 or be retracted to the bottom of the platform 1 through the lifting hole 11, realizing the lifting movement of the gas supply terminal 2 relative to the platform 1, and facilitating gas supply when the gas supply terminal 2 rises to the platform 1, improving the convenience of use, and can also be temporarily hidden when the gas supply terminal 2 is retracted to the bottom of the platform 1, avoiding the problem of occupying the upper space of the platform 1 when no gas is supplied, thereby facilitating the utilization of the upper space of the platform 1.

[0040] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention.
