Description

Technical Field

[0001] This utility model relates to the field of gas storage tanks, specifically a gas storage tank that is easy to move. Background Technology

[0002] A gas storage tank is a device specifically used to store gas and also serves to stabilize system pressure. Based on the pressure it can withstand, gas storage tanks can be classified as high-pressure, low-pressure, and atmospheric-pressure tanks. Based on the material, they can be classified as carbon steel, low-alloy steel, and stainless steel tanks. A gas storage tank (pressure vessel) generally consists of a cylinder, end caps, flanges, connecting pipes, sealing elements, and supports, among other parts and components. In addition, it is equipped with safety devices, gauges, and internal components that perform different production processes.

[0003] In the prior art, such as in CN217899542U, a conveniently movable anti-collision gas tank is disclosed. It includes a base plate with several casters underneath. A push plate is fixedly connected to one end of the base plate, and several shock-absorbing springs are fixedly connected to the top of the base plate. The top of each shock-absorbing spring is fixedly connected to a partition. A limiting block is provided on one side above the partition, and a lead screw is connected inside the limiting block. A crank handle is provided at one end of the lead screw, and a movable seat is sleeved on the outside of the lead screw. A pad is provided on the adjacent side of the movable seat, located at the center above the partition. A screw rod is provided above the pad, and a locking seat is provided above the movable seat. A top rod is connected inside the locking seat, and the top of the top rod is connected to a second locking seat. This utility model, by setting a support rod and other mechanisms that can adjust the direction and center of the gas tank, allows the gas tank to be laid flat during transfer. Furthermore, the shock-absorbing springs and casters on the base plate make the movement of the gas tank more stable and safe.

[0004] Although the aforementioned patent achieves stable transportation through the use of shock-absorbing springs, relying solely on the compression deformation of the springs to absorb energy results in the springs rebounding, which can cause the objects above to sway, leading to poor shock absorption. Furthermore, the lack of structural protection against potential collisions makes the gas tank susceptible to impact damage. Therefore, this paper proposes a gas tank that is easy to move to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, when energy is absorbed solely by the compression deformation of the spring, the subsequent rebound of the spring can cause the object above to sway, resulting in poor shock absorption. At the same time, the lack of structural protection against potential collisions makes the gas storage tank prone to impact damage. This utility model proposes a gas storage tank that is easy to move.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The gas storage tank that is easy to move according to this utility model includes a base, a groove is provided on the top surface of the base, a protective component is fixedly connected inside the groove, a connecting seat is fixedly connected on the top surface of the protective component, a gas storage tank is sleeved on the top surface of the connecting seat, a buffer component is fixedly connected on the bottom surface of the base in an axially symmetrical manner, a caster wheel is fixedly connected on the bottom surface of the buffer component, a bracket is fixedly connected on one side of the base, and a handrail is fixedly connected to the top of the bracket.

[0007] The protective component includes symmetrically formed grooves on the inner walls of both sides of the groove. Rollers are slidably connected inside the two grooves. Rubber sleeves are fitted on the surface of the rollers. A connecting block is sleeved at one end of the rollers through a bearing. A slider is fixedly connected to the side of the connecting block. A sliding rod is fixedly connected to the back of the slider. A sleeve fixed to the inner wall of the groove is connected to the side of the sliding rod through a spring.

[0008] The buffer assembly includes side plates symmetrically fixed to the bottom surface of the base. A positioning rod is fixedly connected between the two side plates. A long spring is sleeved on the surface of the positioning rod. Slip rings that are slidably sleeved on the positioning rod are connected to both ends of the long spring. A clamping plate is connected to the bottom end of the slip ring through an extension rod. The back of the slip ring is connected to the side plate through a hydraulic buffer rod. A caster wheel is fixedly connected to the bottom surface of the clamping plate.

[0009] Preferably, the outer surface of the rubber sleeve has anti-slip texture and its thickness is less than the diameter of the roller.

[0010] Preferably, the bracket has a linear vertical structure, and its connection point with the base is located on one side of the base.

[0011] Preferably, the two ends of the long spring are fixed to the opposite sides of the slip ring, and there is a sliding gap between the slip ring and the positioning rod.

[0012] Preferably, the surface of the handrail is covered with an anti-slip material layer, and a reinforcing rib is provided at the connection between its bottom and the support.

[0013] Preferably, the connection between the connecting seat and the gas storage tank is an annular contact surface, and the annular contact surface is interference-fitted with the outer surface of the gas storage tank.

[0014] The advantages of this utility model are:

[0015] 1. This utility model utilizes the synergistic effect of the positioning rod and the long spring in the buffer assembly, combined with the dual energy-absorbing structure of the slip ring and the hydraulic buffer rod. When encountering bumps during movement, the caster wheel drives the clamping plate to push the slip ring along the positioning rod through the extension rod. The long spring is compressed and deformed to absorb vibration energy. At the same time, the hydraulic buffer rod suppresses the spring rebound through damping, effectively reducing the shaking of the gas tank caused by the reciprocating motion of the spring, and significantly improving the stability of movement.

[0016] 2. This utility model utilizes the sliding fit structure between the roller and the rubber sleeve in the protection component, combined with the elastic buffering mechanism of the slide rod and the spring. When the gas tank is subjected to a side impact, the connecting seat drives the slider to slide along the slide groove, the roller rotates through the bearing to reduce frictional resistance, the slide rod pushes the spring to compress and deform to absorb impact energy, and the rubber sleeve further reduces rigid collisions, forming a multi-level buffer protection to prevent structural damage to the gas tank caused by external impacts.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a portable gas tank includes a base 1. The top surface of the base 1 has a groove, and a protective component 2 is fixedly connected inside the groove. A connecting seat 3 is fixedly connected to the top surface of the protective component 2. A gas tank 4 is sleeved on the top surface of the connecting seat 3. A buffer component 5 is fixedly connected to the bottom surface of the base 1 in an axisymmetric manner. A caster wheel 6 is fixedly connected to the bottom surface of the buffer component 5. A bracket 7 is fixedly connected to one side of the base 1, and a handrail 8 is fixedly connected to the top of the bracket 7. The buffer component 5 includes side plates 51 symmetrically fixed to the bottom surface of the base 1. A positioning rod 52 is fixedly connected between the two side plates 51. A long spring 53 is sleeved on the surface of the positioning rod 52. The two ends of the long spring 53 are connected to slip rings 54 that are slidably sleeved on the positioning rod 52. The bottom end of the slip ring 54 is connected to a clamping plate 56 through an extension rod 55. The back of the slip ring 54 is connected to the side plate 51 through a hydraulic buffer rod. The caster wheel 6 is fixedly connected to the bottom surface of the clamping plate 56.

[0025] During operation, when the gas tank 4 encounters bumps during movement, the caster wheel 6 drives the clamping plate 56 to move upward. The extension rod 55 pushes the slip ring 54 to slide along the positioning rod 52 and compress the long spring 53. At the same time, the hydraulic buffer rod on the back of the slip ring 54 generates damping resistance as the slip ring 54 moves. The elastic deformation of the long spring 53 absorbs the vertical vibration energy. The hydraulic buffer rod suppresses the rebound speed of the long spring 53 through the flow of oil, forming a composite buffer mechanism that effectively reduces the impact force transmitted from the base 1 to the gas tank 4.

[0026] Furthermore, the protective component 2 includes symmetrically opened grooves on the inner walls of both sides of the groove. Rollers 21 are slidably connected inside the two grooves. A rubber sleeve 22 is fitted on the surface of the roller 21. A connecting block 24 is fitted to one end of the roller 21 through a bearing 23. A slider 25 is fixedly connected to the side of the connecting block 24. A sliding rod 26 is fixedly connected to the back of the slider 25. A sleeve 28 fixed to the inner wall of the groove is connected to the side of the sliding rod 26 through a spring 27.

[0027] During operation, when the gas tank 4 is impacted from the side, the connecting seat 3 drives the slider 25 to slide laterally along the groove. The roller 21 rolls in the groove through the bearing 23 to reduce frictional resistance. The slide rod 26 moves with the slider 25 and squeezes the spring 27. The spring 27 is compressed and deformed in the sleeve 28 to absorb the impact energy. At the same time, the rubber sleeve 22 on the surface of the roller 21 buffers the rigid contact through its own elastic deformation. The multi-level protection structure reduces the risk of deformation of the gas tank 4 caused by collision.

[0028] Furthermore, the bracket 7 has a straight vertical structure, and its connection point with the base 1 is located on one side of the base 1;

[0029] During operation, when the operator holds the handle 8 and pushes the gas tank 4 to move, the vertical structure of the straight support 7 makes the direction of the thrust consistent with the direction of movement of the base 1, reducing the torque offset caused by structural bending. The design of the connection point located on one side of the base 1 makes the support 7 and the base 1 form a stable triangular support, avoiding the base 1 from tilting due to uneven force during the pushing process. At the same time, the straight support 7 reduces the overall structural complexity and facilitates processing and assembly. This structure enhances the stability of the movement operation and reduces the risk of tipping by optimizing the force transmission path and support layout.

[0030] Furthermore, the two ends of the long spring 53 are respectively fixed to the opposite sides of the slip ring 54, and there is a sliding gap between the slip ring 54 and the positioning rod 52.

[0031] During operation, when the caster wheel 6 moves upward due to bumps and impacts, the extension rod 55 pushes the slip ring 54 to slide along the positioning rod 52. The two ends of the long spring 53 are simultaneously compressed and contract towards the center, ensuring that the force on both sides of the slip ring 54 is balanced, avoiding stress concentration on one side that could lead to spring deformation and failure. The small gap between the slip ring 54 and the positioning rod 52 limits the lateral displacement of the slip ring 54, ensuring that the slip ring 54 slides smoothly along the axial direction of the positioning rod 52 and reducing unexpected frictional losses. This design improves the durability and energy absorption efficiency of the buffer assembly 5 through symmetrical force constraints and gap control.

[0032] Working principle: When the operator moves the gas tank 4 by pushing it with the handle 8, the casters 6 at the bottom of the base 1 are subjected to vertical impact force due to ground bumps. The clamp 56 drives the slip ring 54 to slide along the positioning rod 52 through the extension rod 55 and compress the long spring 53. At the same time, the hydraulic buffer rod on the back of the slip ring 54 suppresses the rebound speed of the long spring 53 through oil damping, forming a composite energy absorption mechanism to reduce the intensity of vibration transmitted to the base 1. When the gas tank 4 is subjected to a side collision, the connecting seat 3 drives the slider 25 to move laterally along the groove. The roller 21 rolls in the groove through the bearing 23 to reduce frictional resistance. The slide rod 26 pushes the spring 27 to compress and deform in the sleeve 28 to absorb the impact energy. At the same time, the rubber sleeve 22 on the surface of the roller 21 buffers the rigid contact through elastic deformation, realizing multi-level collision protection. Finally, through the synergistic effect of the buffer component 5 and the protection component 2, the stability and impact resistance of the gas tank 4 are ensured during movement.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
