Description

Technical Field

[0001] The invention relates to the technical field of container installation devices, in particular to a stable transportation structure for LNG storage tanks. Background Art

[0002] LNG storage tanks are key equipment for the storage of liquefied natural gas (LNG). The main function of small storage tanks is to meet daily needs, such as civil gas supply, automobile gas stations, etc. LNG tank transport brackets are usually composed of metal frames, including crossbeams, longitudinal beams and support structures connecting these beams. These brackets are fixed to the transport vehicle or ship by welding or bolting to form a stable support platform. The main function of the bracket is to provide sufficient support for the LNG storage tank to prevent the tank from shifting or tipping over due to bumps and vibrations during transportation, and ensure the safe transportation of LNG.

[0003] Traditional brackets are often directly attached to the outer wall of the LNG tank. During transportation, the vibration of the vehicle or ship is easily transmitted directly to the tank through the bracket, causing a collision between the tank and the bracket, which may damage the tank surface.

[0004] The support structure is usually set at the bottom of the support to fix the storage tank. This design makes the support not connected from top to bottom, forming a "closed" support space. Although this structure enhances the stability of the storage tank, it brings inconvenience to the loading and unloading of the storage tank. Especially for the storage tank located deep in the support, the loading and unloading operation is difficult due to its limited space.

[0005] When designing the bracket, the focus is often only on supporting and fixing the entire tank, while ignoring the protection of the tank valve. During transportation, the valve, as one of the key components of the tank, is easily eroded and damaged by external factors such as collision, rain, and debris. Once the valve is damaged, it will directly affect the storage and transportation safety of LNG.

[0006] LNG tank transport brackets have many deficiencies in structural design and functional realization, which makes it difficult to meet the modern LNG transportation industry's requirements for efficiency, safety, and flexibility. Therefore, it is necessary to develop a new type of LNG tank stable transportation structure to overcome the defects of existing brackets and improve the overall level of LNG transportation. Summary of the invention

[0007] To achieve the above object, the present invention provides the following technical solution: a stable transportation structure of an LNG storage tank, comprising:

[0008] A bracket, wherein a plurality of slide grooves are arranged in the horizontal direction and the vertical direction inside the bracket, and a connecting shaft is fixed to the inner walls on both sides of each slide groove;

[0009] A front plate and a rear plate are rotatably connected above the front and rear ends of the slideway, respectively, wherein the front plate and the rear plate are both provided with lock buckles that are fastened to the slideway;

[0010] A plurality of evenly distributed partitions are rotatably connected above the slide slot between the front end plate and the rear end plate to separate the space;

[0011] A storage tank, wherein a valve is provided in front of the storage tank, and hoops are provided at the front and rear of the tank body of the storage tank, and sleeve rings with C-shaped openings are provided on both sides of the hoops;

[0012] Reinforcement rods are fixed to the upper and lower parts of the two hoops, and the front ends of the reinforcement rods extend to a position flush with the valve;

[0013] The collars on both sides of the storage tank are sleeved on the connecting shafts on both sides of the slide slot, thereby allowing multiple storage tanks to be slidably connected in the slide slot.

[0014] Furthermore, preferably, a valve cap is fixed to the middle of the front end plate and each partition plate facing the rear end.

[0015] Furthermore, preferably, a buffer sleeve is fixed to the upper and lower sides of the front end plate and each partition plate facing the rear end, a slider is slidably arranged in the buffer sleeve, and a front spring is further arranged between the slider and the buffer sleeve.

[0016] Further, as a preference, a rotating shaft is fixed above the partition, the rotating shaft is rotatably connected to the slide slot, and a torsion spring is provided in the rotating shaft, and the torsion spring rotates the partition to a horizontal position in a natural state.

[0017] Furthermore, as a preference, a through slot is provided on the slider in each upper buffer sleeve, a linkage pull wire is fixedly connected to the slider, and the other end of the linkage pull wire is fixed to a subsequent partition adjacent thereto.

[0018] Further, preferably, a rear spring is fixed to the rear end plate and a side of each partition plate facing the front end.

[0019] Further, preferably, a one-way device is connected between each of the rotating shafts and the slide slot, the housing of the one-way device is fixedly connected to the slide slot, a ratchet is fixed to one end of the rotating shaft, a ratchet is rotatably connected inside the one-way device, and the ratchet is fitted with the ratchet.

[0020] Furthermore, as a preference, it also includes the unlocking pull wire, which passes through each of the one-way devices in the same slide groove and is fixed above each ratchet tooth.

[0021] Further, as a preference, one end of the unlocking wire close to the rear end plate is connected to a wire puller.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention separates multiple storage tanks into independent spaces through built-in partitions, effectively preventing collisions between storage tanks and reducing potential risks caused by transportation vibrations. The valve cap ensures that the storage tank valve is protected from bumps and erosion by the external environment during transportation, ensuring the safety and functionality of the valve. The front and rear springs provide additional protection for the storage tank, reducing damage to the storage tank and the LNG inside it caused by vibration or impact.

[0024] The design of the slide and connecting shaft in the present invention makes the installation and removal of the storage tank quick and easy, without the need for complex fixing devices or time-consuming preparation work, greatly improving the transportation efficiency. The automatic drop mechanism of the partition simplifies the loading process and reduces manual operation, so that each storage tank can be automatically separated into an independent space, further improving the loading efficiency. The reinforcing rod facilitates the lifting and fixing of the storage tank, making the transportation operation smoother.

[0025] The unlocking pull wire and the one-way device in the present invention enable the partition to be unlocked quickly during unloading, making it easy to remove the storage tanks one by one. The unobstructed upper and lower layer design makes the loading and unloading of the storage tanks easier and also saves transportation space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] See also Figure 1~Figure 5 In an embodiment of the present invention, a stable transportation structure for an LNG storage tank includes:

[0035] A bracket 1, wherein a plurality of slide grooves 2 are arranged in the horizontal direction and the vertical direction inside the bracket 1, and a connecting shaft 21 is fixed to the inner walls of both sides of each slide groove 2;

[0036] A front plate 4 and a rear plate 5 are rotatably connected above the front and rear ends of the slide 2, wherein the front plate 4 and the rear plate 5 are both provided with a lock 6 that is fastened to the slide 2;

[0037] A plurality of evenly distributed partitions 7 are rotatably connected above the slide slot 2 between the front end plate 4 and the rear end plate 5 to separate the space;

[0038] A storage tank 3, wherein a valve 31 is provided in front of the storage tank 3, and a hoop 32 is sleeved on the front and rear of the tank body of the storage tank 3, and sleeve rings 33 with C-shaped openings are provided on both sides of the hoop 32;

[0039] Reinforcement rods 34 are fixed to the upper and lower parts of the two hoops 32, and the front ends of the reinforcement rods 34 extend to a position flush with the valve 31;

[0040] The collars 33 on both sides of the storage tank 3 are sleeved on the connecting shafts 21 on both sides of the slide slot 2, thereby allowing multiple storage tanks 3 to be slidably connected in the slide slot 2.

[0041] Rotating the front plate 4 and the rear plate 5 downward can close the front and rear of the chute 2, and rotating the partition 7 downward can separate multiple storage tanks 3 in the same chute 2 into independent spaces through the partition 7 to avoid collision between the storage tanks 3 during transportation;

[0042] The reinforcing rod 34 not only enhances the structural strength of the storage tank 3, but also facilitates the lifting and fixing operations during transportation;

[0043] The design of the chute 2 and the connecting shaft 21 allows for quick and easy installation and removal of the storage tank 3, thereby improving transportation efficiency and flexibility;

[0044] Since the storage tanks 3 are connected to the connecting shafts 21 on both sides through the collars 33 , there is no supporting structure at the bottom of the chute 2 , so that there is no obstruction between the upper and lower storage tanks 3 , so that the storage tanks 3 can be easily loaded and unloaded in the bracket 1 .

[0045] In this embodiment, a valve cap 72 is fixed to the middle of the front end plate 4 and each partition plate 7 facing the rear end.

[0046] When the storage tank 3 is placed between the partitions 7, the valve cap 72 can cover the valve 31 of the corresponding storage tank 3, thereby protecting the valve 31 from being bumped and eroded by rain and debris.

[0047] See also Figure 6 In this embodiment, a buffer sleeve 73 is fixed to the upper and lower sides of the front end plate 4 and each partition plate 7 facing the rear end, a slider 74 is slidably arranged in the buffer sleeve 73, and a front spring 76 is also arranged between the slider 74 and the buffer sleeve 73.

[0048] When the storage tank 3 is placed between the partitions 7, the front end of the reinforcing rod 34 is inserted into the buffer sleeve 73, and the slider 74 is pushed to compress the front spring 76, so that the front end of the storage tank 3 and the corresponding front end plate 4 or partition 7 have a buffering effect;

[0049] When the front end of the reinforcing rod 34 of the storage tank 3 is inserted into the buffer sleeve 73, the partition 7 is restricted from rotating, and the vibration force and torque at the front end of the storage tank 3 are applied to the reinforcing rod 34 to prevent the valve 31 from being damaged or loosened due to collision.

[0050] In this embodiment, a rotating shaft 71 is fixed above the partition 7, the rotating shaft 71 is rotatably connected to the slide slot 2, and a torsion spring is provided in the rotating shaft 71, and the torsion spring rotates the partition 7 to a horizontal position in a natural state;

[0051] A through slot is formed on the slider 74 in each buffer sleeve 73 at the top, and a linkage wire 9 is fixedly connected to the slider 74 , and the other end of the linkage wire 9 is fixed to the next partition plate 7 adjacent thereto.

[0052] When no storage tank 3 is placed between two adjacent partitions 7, the rear partition 7 is in a horizontal state; when the storage tank 3 is placed between the two partitions 7, the front end of the reinforcing rod 34 of the storage tank 3 is inserted into the buffer sleeve 73, pushing the slider 74 to slide forward. At this time, the linkage pull wire 9 pulls the rear partition 7 to rotate downward, so that the rear partition 7 is in a vertical state to facilitate the placement of the next storage tank 3.

[0053] That is to say, every time a storage tank 3 is placed forward in the chute 2, the rear partition 7 will automatically fall down, thereby separating into an independent space.

[0054] In this embodiment, a rear spring 75 is fixed to the rear end plate 5 and the front end side of each partition plate 7 .

[0055] When the rear end plate 5 or the partition plate 7 is in a vertical state, the rear spring 75 can play a buffering and supporting role on the rear end of the storage tank 3 .

[0056] In this embodiment, a one-way device 8 is connected between each rotating shaft 71 and the slide slot 2, the shell of the one-way device 8 is fixedly connected to the slide slot 2, a ratchet 83 is fixed to one end of the rotating shaft 71, a ratchet 84 is rotatably connected inside the one-way device 8, and the ratchet 84 is in contact with the ratchet 83.

[0057] The one-way device 8 prevents the partition plate 7 from rotating in the reverse direction after rotating downward, thereby preventing the storage tank 3 from sliding back.

[0058] In this embodiment, the unlocking pull wire 81 is also included. The unlocking pull wire 81 runs through each of the one-way devices 8 in the same slide slot 2 and is fixed above each ratchet tooth 84;

[0059] One end of the unlocking wire 81 close to the rear end plate 5 is connected to a wire puller 82 .

[0060] When the wire puller 82 is relaxed, the ratchet 84 fits with the ratchet wheel 83. When the wire puller 82 is tightened, the unlocking wire 81 pulls the ratchet 84 to rotate upward, and the ratchet 84 is separated from the ratchet wheel 83, so that each of the one-way devices 8 in the same slide 2 is unlocked, so that the partition 7 can rotate upward during unloading.

[0061] The specific implementation includes:

[0062] The loading process is carried out from bottom to top;

[0063] Turn the front end plate 4 downward and use the lock buckle 6 to fasten it to the slide slot 2;

[0064] Align the storage tank 3 with the connecting shafts 21 on both sides of the chute 2 through the collars 33 on both sides thereof, and slowly push them in until the collars 33 are completely sleeved on the connecting shafts 21;

[0065] During placement, the reinforcing rod 34 of the storage tank 3 will first contact the buffer sleeve 73 at the rear end of the front plate 4 or the partition 7, pushing the slider 74 to compress the front spring 76, thus playing a buffering role;

[0066] As the storage tank 3 is pushed in, the linkage pull wire 9 will be triggered, automatically rotating the next partition 7 to a vertical position, preparing for the placement of the next storage tank 3;

[0067] Repeat this step until all storage tanks 3 are placed in the chute 2 as required;

[0068] The rear end plate 5 is rotated downward and fastened to the chute 2 using the lock 6 to close the front and rear ends of the chute 2. At this time, the partition 7 is also in a vertical state, separating the multiple storage tanks 3 in the same chute 2 into independent spaces.

[0069] The front and rear ends of each storage tank 3 are buffered and protected by a front spring 76 and a rear spring 75, and the valve 31 of each storage tank 3 is covered by a valve cap 72 on the front end plate 4 or the partition plate 7 to protect it from collision and erosion by the external environment.

[0070] The unloading process is carried out from top to bottom;

[0071] Use the wire puller 82 to tighten the unlocking wire 81, so that the ratchet teeth 84 in all the one-way devices 8 in the same slide 2 rotate upward and separate from the ratchet wheel 83, thereby releasing the lock on the partition 7;

[0072] Unlock and open the lock 6 of the rear end plate 5, rotate the rear end plate 5 upward, and open the rear end of the slide 2;

[0073] Starting from the rear end of the slide 2, the storage tanks 3 are pulled out one by one. When the storage tanks 3 are pulled out, the reinforcing rods 34 thereof will be separated from the buffer sleeve 73, the front spring 76 will return to its original position, and the slider 74 will return to its initial position;

[0074] As the storage tank 3 is removed, the rear partition 7 automatically rotates back to the horizontal position under the action of the torsion spring.

[0075] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
