Description

Technical Field

[0001] This utility model relates to the field of liquid storage tank technology, and in particular to a cryogenic liquid storage tank installation device. Background Technology

[0002] Cryogenic liquid storage tanks are essential equipment for storing cryogenic liquefied gases such as liquid oxygen, liquid nitrogen, and liquefied natural gas (LNG), and are widely used in chemical, energy, medical, and aerospace industries. Due to the extremely low temperature characteristics of the stored media (typically below -160°C), stringent safety and stability requirements must be met in structural design, material selection, and installation processes. The installation quality of the storage tank directly affects its operational safety, sealing performance, and service life. Ensuring stable placement, precise positioning, and robust support of the tank is particularly crucial during transportation and on-site installation.

[0003] Specifically, existing installation methods for cryogenic liquid storage tanks mostly employ traditional gantry frames supported by manual jacks or simple brackets, lacking adjustable support structures and failing to flexibly adapt to tank size, weight distribution, and installation height. For example, utility model patent CN203211817U discloses a storage tank for cryogenic transport equipment. This tank has an axially installed vapor phase pipe, one end of which is connected to an external safety relief device. The other end of the vapor phase pipe has a splash-proof elbow at its inlet, with the free end of the elbow opening upwards and positioned above the maximum liquid level, effectively preventing cryogenic liquid from entering the vapor phase pipe and ensuring the normal operation of the safety relief device. While this structure improves the safety of the internal gas passage of the tank, it does not solve the technical challenges faced during the installation phase.

[0004] Currently, existing equipment commonly suffers from the following problems during actual installation: First, it lacks an adjustable support mechanism, making it difficult to adapt to tanks of different diameters and heights; second, the support structure lacks rigidity, making it prone to tilting or slippage during hoisting, posing significant safety hazards; third, installation efficiency is low, with most operations relying on repeated manual calibration and auxiliary support, resulting in long construction cycles and high labor intensity. These problems not only significantly increase construction costs and operational risks but may also affect the sealing and stability of the tank's subsequent operation due to installation deviations, thereby threatening the safe operation of the entire system. Therefore, given the numerous shortcomings of existing technologies, we urgently need an innovative cryogenic liquid storage tank installation equipment to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a cryogenic liquid storage tank installation device, which solves the problems of existing technologies that lack adjustable support mechanisms, are difficult to adapt to storage tanks of different diameters and heights, have low installation efficiency, and rely on manual repeated calibration and auxiliary support for most operations, resulting in long construction cycles and high labor intensity.

[0006] To achieve the above objectives, this utility model provides a cryogenic liquid storage tank installation device, including a frame, a bearing plate slidably connected to the inner side of the frame, and a hydraulic cylinder fixedly connected to the bottom side of the frame by bolts.

[0007] The output shaft of the hydraulic cylinder passes through the bottom of the frame and is fixedly connected to the bottom of the support plate. A support frame is slidably connected to the top of the support plate. A hydraulic pipe is slidably connected to one side of the frame, and a piston pipe is connected to one side of the hydraulic pipe. A piston is provided inside the piston pipe. A piston rod is fixedly connected to one side of the piston, and one end of the piston rod passes through the piston pipe and is fixedly connected to one side of the support frame. A hydraulic pump is fixedly connected to one side of the frame by bolts, and the connection of the hydraulic pump is connected to one side of the hydraulic pipe through an adjusting pipe.

[0008] The bottom of the support frame is fixedly connected to a sliding block, and the sliding block is slidably connected to the top of the bearing plate through a sliding groove.

[0009] The support plate has sliders fixedly connected to both sides, and the sliders are slidably connected to the side wall of the frame through a groove.

[0010] One side of the bearing plate is fixedly connected to an inclined plate.

[0011] The support frame is fixedly connected to telescopic rods on both sides, and one end of each telescopic rod is fixedly connected to one side of the hydraulic pipe.

[0012] The hydraulic pipe has protrusions fixedly connected to both sides, and the two protrusions are slidably connected to the side wall of the frame through vertical grooves.

[0013] This utility model discloses a cryogenic liquid storage tank installation device. Through the linkage between the hydraulic cylinder and the support plate, it achieves flexible adjustment of the tank installation height, solving the problem of traditional installation equipment lacking an adjustable support mechanism and being unable to adapt to different specifications of storage tanks, thus improving the equipment's versatility and applicability. Secondly, through a hydraulic drive system composed of a hydraulic pump, hydraulic pipe, piston pipe, piston, and piston rod, the support frame can achieve precise horizontal displacement control, effectively addressing the installation deviation problem caused by the non-adjustable support structure of existing installation equipment, and improving installation accuracy and docking efficiency. Thirdly, the overall structure uses a rigid frame as the basic support platform, combined with a sliding connection between the support plate and the support frame, enhancing the stability and safety of the equipment during hoisting, avoiding the risk of tilting or slippage caused by insufficient rigidity of the support structure, and reducing construction safety hazards.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A cryogenic liquid storage tank installation device includes a frame 1, and a support plate 2 slidably connected to the inner side of the frame 1. A hydraulic cylinder 18 is fixedly connected to one side of the bottom of the frame 1 by bolts. The output shaft of the hydraulic cylinder 18 passes through the bottom of the frame 1 and is fixedly connected to the bottom of the support plate 2. A support frame 3 is slidably connected to the top of the support plate 2. A hydraulic pipe 8 is slidably connected to one side of the frame 1, and a piston pipe 10 is connected to one side of the hydraulic pipe 8. A piston 16 is provided inside the piston pipe 10. A piston rod 11 is fixedly connected to one side of the piston 16, and one end of the piston rod 11 passes through the piston pipe 10 and is fixedly connected to one side of the support frame 3. A hydraulic pump 12 is fixedly connected to one side of the frame 1 by bolts, and the connection of the hydraulic pump 12 is connected to one side of the hydraulic pipe 8 through an adjusting pipe 13.

[0023] During the installation of the cryogenic liquid storage tank, the tank to be installed is first placed stably inside the support frame 3, ensuring that the bottom of the tank is in uniform contact with the support frame 3. Then, the hydraulic cylinder 18, fixedly connected to one side of the bottom of the frame 1, is activated. Its output shaft pushes the bearing plate 2 to slide up and down along the inner side of the frame 1, thereby adjusting the height of the support frame 3 and the tank on it to meet different installation height requirements. Simultaneously, after the height adjustment is completed, the hydraulic pump 12, fixedly connected to one side of the frame 1, is activated. The hydraulic pump 12 delivers hydraulic oil to the hydraulic pipe 8 through the regulating pipe 13, and the oil continues to flow into the piston pipe 10, pushing the piston 16 towards the tank, thereby driving the piston 16... The fixedly connected piston rod 11 moves synchronously. One end of the piston rod 11 passes through the piston tube 10 and is fixedly connected to one side of the support frame 3, thereby driving the support frame 3 to slide horizontally along one side of the frame 1, realizing fine adjustment of the lateral position of the storage tank. Through the coordinated action of the hydraulic cylinder 18 and the hydraulic pump 12, the height adjustment and lateral displacement adjustment of the storage tank are completed respectively, so that the storage tank can be accurately positioned to the target installation position, ensuring the docking accuracy between it and the supporting equipment or foundation structure. Throughout the process, the support frame 3 and the bearing plate 2 are slidably connected, which facilitates flexible adjustment of the support position according to the actual installation requirements. At the same time, the hydraulic system has good load capacity and response speed, ensuring the stability and controllability of the operation process.

[0024] Furthermore, a sliding block 9 is fixedly connected to the bottom of the support frame 3, and the sliding block 9 is slidably connected to the top of the bearing plate 2 through the sliding groove 17. This makes the support frame 3 more stable and precise when it moves laterally under the drive of the hydraulic system, ensuring that the tank can be finely adjusted in the horizontal direction without obstruction. This avoids positional deviation problems caused by friction or jamming, and improves the accuracy and reliability of equipment operation.

[0025] Furthermore, sliders 5 are fixedly connected to both sides of the support plate 2, and the sliders 5 are slidably connected to the side wall of the frame 1 through the sliding groove 6. During the process of the hydraulic cylinder 18 pushing the support plate 2 up and down, it can effectively prevent the support plate 2 from shifting or tilting, thus enhancing the stability of the entire device during vertical adjustment. This design not only ensures the accuracy of height adjustment but also extends the service life of the equipment and reduces maintenance costs.

[0026] Furthermore, an inclined plate 4 is fixedly connected to one side of the support plate 2. This design of the inclined plate 4 provides operators with an easy-to-access and supportive operating platform for the side of the storage tank, increasing the safety and convenience of the operation. Especially during the installation of the storage tank, when additional support or auxiliary operations are required, the inclined plate 4 can serve as a temporary support point or operating interface, improving overall work efficiency.

[0027] Furthermore, telescopic rods 7 are fixedly connected to both sides of the support frame 3, and one end of each telescopic rod 7 is fixedly connected to one side of the hydraulic pipe 8. When the piston rod 11 drives the support frame 3 to make horizontal displacement, the telescopic rods 7 can extend or retract synchronously, providing additional support and guidance for the support frame 3. This not only enhances the stability of the support frame 3 during movement, but also further ensures the safety of the storage tank when adjusting its position, reducing potential risks.

[0028] Furthermore, both sides of the hydraulic pipe 8 are fixedly connected to protrusions 14, and both protrusions 14 are slidably connected to the side wall of the frame 1 through vertical grooves 15. This ensures that the hydraulic pipe 8 maintains the correct trajectory as it moves with the piston rod 11, preventing any possible shaking or deviation from the path. This design helps maintain the normal working condition of the hydraulic system, ensuring smooth flow of hydraulic oil and efficient pressure transmission, thereby improving the overall performance and response speed of the equipment. At the same time, it also enhances the safety and stability of equipment operation, ensuring that every operation is completed accurately.

[0029] In summary:

[0030] During the installation of the cryogenic liquid storage tank, the tank to be installed is first placed stably inside the support frame 3, ensuring that the bottom of the tank is in uniform contact with the support frame 3. Then, the hydraulic cylinder 18, fixedly connected to one side of the bottom of the frame 1, is activated. Its output shaft pushes the bearing plate 2 to slide up and down along the inner side of the frame 1, thereby adjusting the height of the support frame 3 and the tank on it to meet different installation height requirements. Simultaneously, after the height adjustment is completed, the hydraulic pump 12, fixedly connected to one side of the frame 1, is activated. The hydraulic pump 12 delivers hydraulic oil to the hydraulic pipe 8 through the regulating pipe 13, and the oil continues to flow into the piston pipe 10, pushing the piston 16 towards the tank, which in turn moves the piston rod 1, fixedly connected to the piston 16. 1. Synchronous movement: One end of the piston rod 11 passes through the piston tube 10 and is fixedly connected to one side of the support frame 3, thereby driving the support frame 3 to slide horizontally along one side of the frame 1, achieving fine adjustment of the lateral position of the storage tank; through the coordinated action of the hydraulic cylinder 18 and the hydraulic pump 12, the height adjustment and lateral displacement adjustment of the storage tank are completed respectively, enabling the storage tank to be accurately positioned to the target installation position, ensuring the docking accuracy between it and the supporting equipment or foundation structure; throughout the process, the support frame 3 and the bearing plate 2 are slidably connected, which facilitates flexible adjustment of the support position according to actual installation requirements. At the same time, the hydraulic system has good load capacity and response speed, ensuring the stability and controllability of the operation process; in addition, a sliding block 9 is fixedly connected to the bottom of the support frame 3, and through... The sliding groove 17 forms a sliding fit with the top of the support plate 2, making the support frame 3 move more smoothly and steadily in the lateral direction, effectively avoiding jamming or displacement caused by frictional resistance; both sides of the support plate 2 are fixedly connected to sliders 5, which form a sliding connection with the side wall of the frame 1 through the sliding groove 6. During the process of the hydraulic cylinder 18 pushing the support plate 2 to rise and fall, this structure enhances the guidance and stability of the support plate 2, prevents tilting or shaking, and improves the adjustment accuracy of the device in the vertical direction; one side of the support plate 2 is also fixedly connected to an inclined plate 4, which serves as an auxiliary operating platform, making it easier for operators to approach the side of the storage tank for observation or auxiliary support, improving the safety and convenience of the installation process; both sides of the support frame 3 are fixedly connected to The telescopic rods 7, with one end of each of the two telescopic rods 7 fixedly connected to one side of the hydraulic pipe 8, extend or retract synchronously when the piston rod 11 pushes the support frame 3 to make horizontal displacement. This not only enhances the structural strength of the support frame 3 but also provides additional guiding support, improving stability and safety during movement. Both sides of the hydraulic pipe 8 are fixedly connected to protrusions 14, which form a sliding fit with the side wall of the frame 1 through the vertical groove 15. This ensures that the hydraulic pipe 8 always runs along a predetermined trajectory during the movement of the piston rod 11, avoiding shaking or deviation from the path caused by uneven force on the hydraulic pipe 8. This helps maintain the normal working state of the hydraulic system and improves the hydraulic oil flow efficiency and pressure transmission stability.First, the linkage between the hydraulic cylinder 18 and the bearing plate 2 enables flexible adjustment of the tank installation height, solving the problem of traditional installation equipment lacking an adjustable support mechanism and being unable to adapt to tanks of different specifications, thus improving the equipment's versatility and applicability. Second, the hydraulic drive system composed of the hydraulic pump 12, hydraulic pipe 8, piston pipe 10, piston 16, and piston rod 11 enables precise horizontal displacement control of the support frame 3, effectively addressing the installation deviation problem caused by the non-adjustable support structure of existing installation equipment, and improving installation accuracy and docking efficiency. Third, the cooperation between the sliding block 9 at the bottom of the support frame 3 and the sliding groove 17 at the top of the bearing plate 2 makes the support frame 3 move more smoothly and steadily in the lateral direction, avoiding positional deviation problems caused by friction or jamming, and improving the accuracy and reliability of equipment operation. Furthermore, the structural design of the sliders 5 on both sides of the bearing plate 2 and the sliding grooves 6 on the side wall of the frame 1 effectively prevents the bearing plate 2 from shifting or tilting during lifting, enhancing the stability of the entire device during vertical adjustment and extending the service life of the equipment. At the same time, the inclined plate 4 on one side of the bearing plate 2 provides operators with a convenient operating platform, improving the safety and efficiency of installation work. The telescopic rods 7 on both sides of the support frame 3 not only enhance the structural strength of the support frame 3 during movement but also provide good guiding support, ensuring the safety of the storage tank when adjusting its position. The sliding connection structure of the protrusions 14 on both sides of the hydraulic pipe 8 and the vertical groove 15 ensures that the hydraulic pipe 8 maintains the correct trajectory during operation, preventing the hydraulic pipe 8 from affecting the normal operation of the hydraulic system due to shaking or deviation from the path, thus improving the overall performance and response speed of the equipment.
