Description

Technical Field

[0001] The utility model relates to the technical field of gas application, and particularly to a manual and automatic integrated lifting drive structure for a gas supply terminal. Background Technique

[0002] With the development of technology and the improvement of processes, the frequency of gas application is getting higher and higher, and the application range is getting wider and wider. For example, gases such as oxygen are used in the cutting process, gases such as nitrogen are required in the welding process, and air is used in the pressurization process. Therefore, the reasonable utilization of gases has become the research direction of the industry.

[0003] Currently, the existing gas supply terminals on the market usually directly arrange the main structure on a relatively stable platform, which is convenient for pipeline connection and control, and is easy to install and use. Although the existing structure can already meet the gas usage requirements, for some usage scenarios with limited platform space, the upper space of the platform itself is very limited. Especially when the upper space of platforms such as the decks of transport ships needs to be utilized, when the gas supply terminal is directly installed in the upper space of the platform, although it can provide convenience during gas usage, when the gas is not needed, the gas supply terminal still occupies the upper space of the platform, and the staff cannot utilize the space it occupies anymore, resulting in waste of space. In addition, although there are also structures on the market that install the gas supply terminal below the platform, that is, the gas supply terminal is hidden below the platform and does not occupy the upper space of the platform, and the upper space of the platform can be fully utilized. However, every time the gas supply terminal is used, the operator needs to move to the lower space of the platform for pipeline connection and control. Not only is there a problem of inconvenient installation and use, but it is also difficult to obtain the scene changes in the upper space of the platform during gas usage, which is not conducive to controlling the gas supply terminal, thus affecting the use of the gas supply terminal.

[0004] In summary, the existing gas supply terminals cannot take into account the convenience of use and control and the avoidance of space occupation, and there are problems with usage limitations. Summary of the Invention

[0027] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following embodiments are combined with the attached Figure 1 to the attached Figure 4 to specifically elaborate on the technical solutions provided by the present utility model, but the following content shall not be used as a limitation to the present utility model.

[0028] Figure 1 is a structural diagram of a perspective view of a manual-automatic integrated lifting drive structure of a gas supply terminal of the present utility model; Figure 2 is a structural diagram of another perspective view of a manual-automatic integrated lifting drive structure of a gas supply terminal of the present utility model. As Figure 1 and Figure 2 shown, the manual-automatic integrated lifting drive structure of the gas supply terminal provided in this embodiment is used to install the gas supply terminal 1 on the platform 2 to meet the use requirement that the gas supply terminal 1 makes a lifting movement relative to the platform 2. At this time, a lifting opening 21 is provided on the platform 2, and the manual-automatic integrated lifting drive structure is arranged at the bottom of the platform 2 and is located below the lifting opening 21 in the vertical direction, so that the manual-automatic integrated lifting drive structure can drive the gas supply terminal 1 to perform a lifting movement in the lifting opening 21. In addition, the manual-automatic integrated lifting drive structure of the gas supply terminal 1 provided in this embodiment includes: a lifting frame 3, a push rod 4, and a manual-automatic integrated driver 5.

[0029] Specifically, the lifting frame 3 includes a lifting inner cavity 31, and the top of the lifting frame 3 is fixed to the bottom surface of the platform 2, realizing the stable installation of the lifting frame 3 on the platform 2. After the lifting frame 3 is installed in place, the upper opening of the lifting inner cavity 31 communicates with the lifting opening 21, providing conditions for the gas supply terminal 1 subsequently arranged in the lifting inner cavity 31 to move upward and move out of the lifting opening 21 into the upper space of the platform 2.

[0030] Specifically, the push rod 4 is installed on the lifting frame 3 and located in the lifting inner cavity 31. At this time, the push rod 4 is used as a lifting structure in the lifting inner cavity 31. During installation, the telescopic rod body of the push rod 4 is connected to the gas supply terminal 1, providing conditions for driving the gas supply terminal 1 to lift. At the same time, the input shaft of the push rod 4 extends outside the lifting inner cavity 31, providing conditions for connecting the input shaft of the push rod 4 with the manual-automatic drive 5 in the future. It should be noted that the push rod 4 can be a push rod 4 commonly used in the market that adopts a screw pair, which can be directly purchased and installed for use. In addition, the adopted push rod 4 includes but is not limited to having an outer tube, an inner tube, a screw rod, and a nut. The inner tube and the outer tube are axially slidably sleeved and circumferentially limited to each other. The nut is fixed on the inner tube, and the screw rod is threadedly connected to the nut. One end of the screw rod is rotatably installed on the outer tube, and the end of the screw rod rotatably installed on the outer tube extends out and is used as the input shaft of the push rod 4. When the screw rod rotates, the nut can move along the axial direction of the screw rod, so as to realize the axial sliding of the inner tube relative to the outer tube and meet the telescopic requirements.

[0031] Specifically, the manual-automatic drive 5 is arranged outside the lifting inner cavity 31 and is power-connected to the input shaft of the push rod 4, which facilitates the control operation and also enables the manual-automatic drive 5 to be used as the power structure of the push rod 4. And the manual-automatic drive 5 further includes a reduction gearbox 51, a motor 52, and a handwheel 53. During installation, the output shaft of the reduction gearbox 51 is power-connected to the input shaft of the push rod 4 to realize the power connection between the manual-automatic drive 5 and the push rod 4. In addition, the motor 52 is installed on the reduction gearbox 51 and the electric main shaft is connected to the input shaft of the reduction gearbox 51, so that the motor 52 can input power into the reduction gearbox 51, that is, realize the automatic drive of the push rod 4. At the same time, a handwheel 53 is also power-connected to the input shaft of the reduction gearbox 51, so that the handwheel 53 can also input power into the reduction gearbox 51 to meet the use requirement of manually driving the push rod 4 to move, achieving the purpose of manual-automatic lifting. That is, under normal circumstances, the lifting can be realized through the motor 52, and when an accident occurs and the motor 52 cannot work normally, the operator can realize manual lifting through the handwheel 53, with a more flexible structure and better adaptability.

[0032] Figure 3 This is a power schematic diagram of the manual-automatic lifting drive structure of a gas supply terminal of the present utility model. As Figures 1 to 3As shown, the input shaft of the reduction gearbox 51 includes an input main shaft 511, a first input shaft 512 and a second input shaft 513, and a first gear set 514 is provided between one end of the input main shaft 511 and the first input shaft 512, that is, the input main shaft 511 and the first input shaft 512 are transmitted through the first gear set 514, and at the same time, the first input shaft 512 is connected to the electric main shaft power of the motor 52, that is, the power of the motor 52 is transmitted to the input main shaft 511 through the first input shaft 512 and the first gear set 514, thereby driving the input main shaft 511 to rotate, meeting the use requirements of the motor 52 drive. In addition, a second gear set 515 is provided between one end of the input spindle 511 and the second input shaft 513, that is, the input spindle 511 and the second input shaft 513 are driven by the second gear set 515, and the second input shaft 513 is connected to the hand wheel 53 by power, that is, the power of the hand wheel 53 can be transmitted to the input spindle 511 through the second input shaft 513 and the second gear set 515, thereby driving the input spindle 511 to rotate, meeting the use requirements of manual drive, that is, the motor 52 and the hand wheel 53 can both act on the input spindle 511, and realize the purpose of manual-automatic driving of the input spindle 511 to rotate. At the same time, the other end of the input spindle 511 is used as the output shaft of the reduction box 51 and is connected to the input shaft of the push rod 4 by power, so that when the input spindle 511 rotates, it can drive the input shaft of the push rod 4 to rotate, thereby providing power for the extension and retraction of the push rod 4, that is, realizing the manual-automatic control of the action of the push rod 4.

[0033] More specifically, the first gear set 514 and the second gear set 515 are both bevel gear sets, so that bevel gears rotate between the first input shaft 512 and the input main shaft 511 and between the second input shaft 513 and the input main shaft 511, which can not only meet the needs of stable power transmission, but also change the transmission direction, thereby arranging more structures in the shell of the reduction gearbox 51 with a smaller space, which is beneficial to the miniaturized design of the reduction gearbox 51 and reduces space occupancy.

[0034] More specifically, there is a gear transmission between the electric spindle of the motor 52 and the first input shaft 512, which can achieve stable transmission of power between the electric spindle of the motor 52 and the first input shaft 512, with higher transmission efficiency, more stable power, and can extend the service life of the transmission structure.

[0035] Figure 4 This is a structural diagram of a manual and automatic lifting drive structure of a gas supply terminal of the utility model after the hand wheel is removed. Figure 1 , Figure 2 as well as Figure 4As shown in the figure, the handwheel 53 is detachably connected to the second input shaft 513, that is, the handwheel 53 can be installed on the second input shaft 513 during use and can be removed from the second input shaft 513 after use. This not only meets the need to install the handwheel 53 when it is required, but also enables the storage of the handwheel 53 when it is not in use, avoiding space occupation. At the same time, it can also avoid the safety risks caused by the second input shaft 513 rotating along with the rotation of the input main shaft 511 driven by the motor 52, resulting in the handwheel 53 also rotating, providing higher safety protection.

[0036] More specifically, the end of the second input shaft 513 connected to the handwheel 53 extends outside the housing of the speed reducer 51, facilitating the disassembly and assembly of the handwheel 53 on the second output shaft. Moreover, a protruding spline is axially provided on the side wall of the end of the second input shaft 513 extending outside the housing of the speed reducer 51. At the same time, a keyway 531 matching the spline is axially opened on the wheel shaft sleeve of the handwheel 53. When the handwheel 53 is installed on the second input shaft 513, the wheel shaft sleeve of the handwheel 53 is sleeved outside the second input shaft 513, and the spline is snapped into the keyway 531, realizing the circumferential limit between the handwheel 53 and the second input shaft 513, thus ensuring that the handwheel 53 can stably drive the second input shaft 513 to rotate. In addition, both ends of the keyway 531 on the wheel shaft sleeve of the handwheel 53 penetrate the two end faces of the wheel shaft sleeve. That is, when the handwheel 53 is installed on the second input shaft 513, it can be directly sleeved along the axial direction of the second input shaft 513 and pushed to the end to complete the installation of the handwheel 53 on the second input shaft 513. Conversely, the handwheel 53 can be directly pulled out along the axial direction of the second input shaft 513 to realize the disassembly of the handwheel 53 from the second input shaft 513, making the disassembly and assembly more convenient.

[0037] More specifically, a turning handle 532 is also axially provided on the rim of the handwheel 53. When the operator controls the handwheel 53, the handwheel 53 can be rotated by holding the turning handle 532, making the operation more labor-saving and more convenient to use.

[0038] More specifically, the power transmission between the input main shaft 511 and the input shaft of the push rod 4 is realized by the worm gear 7 and worm 6 transmission method. At this time, a worm 6 is provided at the end of the input main shaft 511 that cooperates with the input shaft of the push rod 4, and a worm gear 7 that cooperates with the worm 6 is provided on the input shaft of the push rod 4. While meeting the power transmission requirements between the input main shaft 511 and the input shaft of the push rod 4, it can also realize the one-way transmission of the transmission direction and reverse self-locking, so that only the input main shaft 511 drives the push rod 4 to act during the action process, and the input shaft of the push rod 4 cannot drive the input main shaft 511 to rotate in the reverse direction, thereby preventing the problem of automatic lifting due to accidental failure during the lifting and lowering of the push rod 4, providing higher safety protection.

[0039] More specifically, an isolation cover 32 is further arranged outside the lifting frame 3. At this time, the lifting inner cavity 31 is located inside the isolation cover 32. At the same time, the manual-automatic integrated driver 5 is arranged outside the isolation cover 32. That is, the isolation between the push rod 4 and the manual-automatic integrated driver is achieved through the isolation cover 32, so that the gas supply terminal 1 arranged in the lifting embedding can be isolated from the motor 52 of the manual-automatic integrated driver 5, thus meeting the electrical isolation requirements and improving the safety. In addition, the input shaft of the push rod 4 extends into the reduction gearbox 51 after passing through the isolation cover 32, ensuring the power connection between the push rod 4 and the manual-automatic integrated driver 5 and meeting the power transmission requirements.

[0040] More specifically, a plurality of guide rails 33 are further arranged in the lifting inner cavity 31 along the vertical direction. At the same time, a pulley is slidably arranged in each guide rail 33, and the pulley is rotatably installed on the side wall of the gas supply terminal 1. When the gas supply terminal 1 is lifted and lowered under the action of the push rod 4, the pulley can guide the lifting of the gas supply terminal 1 by sliding in the corresponding guide rail 33, maintaining the stability of the gas supply terminal 1 during lifting and lowering. At the same time, each guide rail 33 adopts a structure with a cross-section in a "U" shape, so that the guide rail 33 has an open sliding space. And when the pulley is installed in the corresponding guide rail 33, gaps are provided between the two sides of the pulley and the two side groove walls of the guide rail 33, so that there is a floating space between the pulley and the corresponding guide rail 33. That is, after the lifting frame 3 or the guide rail 33 undergoes slight deformation during long-term use or in case of an accident, the pulley can still slide in the guide rail 33, avoiding the problem of the pulley being stuck after slight deformation, extending the service life and reducing the maintenance cost.

[0041] The manual-automatic lifting drive structure of the gas supply terminal provided in this embodiment includes a lifting frame 3, a push rod 4, and a manual-automatic integrated driver 5. By installing the lifting frame 3 with a lifting inner cavity 31 below the lifting opening 21 of the platform 2, arranging the push rod 4 in the lifting inner cavity 31 to lift the gas supply terminal 1, and power-connecting the input shaft of the push rod 4 to the manual-automatic integrated driver 5 arranged outside the lifting inner cavity 31, the lifting and lowering operation of the gas supply terminal 1 in the lifting opening 21 is realized, ensuring that it is located on the platform 2 during use for convenient pipeline connection and control, and can be hidden under the platform 2 when not in use to avoid occupying the upper space of the platform 2. In addition, the input shaft of the reduction gearbox 51 of the manual-automatic integrated driver 5 is connected with a motor 52 and a handwheel 53, which can not only meet the automatic driving requirements of the motor 52 but also meet the manual driving requirements, realizing the manual-automatic driving of the push rod 4. The driving method is diverse, meeting different driving scenarios, with a higher error tolerance and better adaptability.

[0042] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model thereby. For those skilled in the art, it should be realized that all the solutions obtained by equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
