Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for transporting storage tanks, and specifically to a protective device for transporting natural gas storage tanks. Background Technology

[0002] The main component of liquefied natural gas (LNG) is methane, with small amounts of ethane and propane. LNG is colorless, odorless, non-toxic, and non-corrosive. LNG storage is one method of natural gas storage.

[0003] Protective devices are required for the transportation of natural gas storage tanks. However, most existing protective devices for transporting natural gas storage tanks rely on ropes for securing them. During transportation, natural gas storage tanks are often transported horizontally to lower the center of gravity and reduce the risk of tipping over. However, traditional transportation protective devices suffer from insufficient cushioning and shock absorption, making them prone to impacts and scratches. Road bumps during transportation can cause vibrations and displacement of the storage tanks. Traditional protective devices often use rigid supports and lack elastic cushioning structures. Direct contact and collision between the storage tank and the supporting components can easily cause impacts and scratches to the outer wall of the storage tank, damaging the anti-corrosion layer, shortening the service life of the storage tank, and in severe cases, potentially leading to leakage risks. Utility Model Content

[0004] In view of this, the present invention provides a protective device for transporting natural gas storage tanks. It can achieve efficient and stable support for the storage tank by using elastic elements in conjunction with supporting arc plates and arc-shaped clamping plates. This solves the problems of insufficient buffering and shock absorption, and easy collision and scratching of traditional transportation protective devices in practical applications: During transportation, road bumps will cause the storage tank to vibrate and shift. Traditional protective devices mostly use rigid supports and lack elastic buffer structures. The storage tank and the supporting components directly contact and collide, which can easily cause collisions and scratches on the outer wall of the storage tank, damage the anti-corrosion layer, shorten the service life of the storage tank, and may even cause leakage risks in severe cases.

[0005] To solve the above-mentioned technical problems, this utility model provides a protective device for transporting natural gas storage tanks, including a support frame. The support frame is equipped with protective components, which are divided into two groups. A support arc plate adapted to the outer wall of the storage tank is set between the two groups of protective components. The storage tank is located between the two groups of protective components and placed on the support arc plate. The protective components include a support plate set on the outside of the support frame, an elastic element set on the support plate, a vertical plate set on the upper part of the elastic element, and an arc-shaped clamping plate adapted to the outer wall of the storage tank set on the upper part of the vertical plate. This utility model can achieve a firm and stable support for the storage tank by using the support arc plate in conjunction with the arc-shaped clamping plate. The elastic element facilitates the elastic support of the arc-shaped clamping plate, which can reduce the risk of the storage tank being bumped and scratched by bumpy roads during transportation, and greatly improve the safety performance during transportation.

[0006] The support plate is L-shaped, and the horizontal part of the support plate is welded to the outer wall of the bracket. The elastic element is located on the upper part of the horizontal part of the support plate.

[0007] The elastic element includes a fixed cylinder located on the upper part of the horizontal section of the support plate, with a spring inside the fixed cylinder and a vertical plate located on the upper part of the spring. This utility model can achieve a firm support operation for the storage tank between the various arc-shaped clamping plates of the chain through the upward support force of the spring, the vertical plate, and the arc-shaped clamping plate. At the same time, it can also provide good buffering and shock absorption during bumpy transportation and reduce mechanical wear.

[0008] The support includes a pair of slide rails, with sliders slidably mounted at both ends of the slide rails. Slide plates are positioned between the two sliders, which are located on the same straight line as the two slide rails. The two slide plates have threaded through holes with opposite threads. A bidirectional screw is threaded into the threaded through holes on the two slide plates. Each slide plate has a supporting arc plate. This invention allows the slide plate to rotate by turning the bidirectional screw. Due to the threaded connection between the slide plate and the bidirectional screw, as well as the guiding and limiting effect of the slide rails on the sliders and the fixing effect of the sliders and slide plates, the rotating bidirectional screw drives the slide plate to slide along the slide rails. This facilitates adjustment of the distance between the supporting arc plates on the two slide plates, enabling secure support for storage tanks of different heights and enhancing its applicability.

[0009] There are two supporting arc plates, located at both ends of the bracket. A pair of fixed arc plates are set between the two supporting arc plates, located at both ends of the vertical line where the midpoint of the bracket is located.

[0010] The end of the bidirectional screw is equipped with a force-applying component.

[0011] The force-applying component has an internal hexagonal screw hole, and this utility model can achieve the rotation of the force-applying component with the help of an internal hexagonal power tool or an internal hexagonal wrench.

[0012] The highest point of the arc-shaped pallet is less than or equal to the horizontal height of the axis of the storage tank after it is laid horizontally, which facilitates the horizontal laying operation of the storage tank.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. High stability due to multiple arc plates surrounding the fixed structure: This utility model can form a ring-shaped fixed structure by supporting the arc plates to bear the weight, fixing the arc plates in the middle to constrain them, and using arc-shaped clamping plates for lateral positioning. This can effectively prevent the storage tank from sliding and rotating during sudden braking and turning, solving the problems of unstable fixing and easy displacement of storage tanks in traditional devices, and ensuring safety during transportation.

[0014] 2. Ample elastic cushioning to prevent bumps and scratches: This utility model can effectively absorb the vibration energy generated by transportation bumps through the spring steel spring in the elastic component. Combined with the fitting constraint of the arc-shaped clamp, it avoids rigid collisions between the storage tank and the supporting components, protects the outer wall and anti-corrosion layer of the storage tank, solves the problem of insufficient cushioning of traditional devices and easy to cause bumps and scratches to the storage tank, extends the service life of the storage tank, and reduces the risk of leakage.

[0015] 3. Adjustable support spacing and strong adaptability: This utility model can flexibly adjust the distance between the support arc plates by using the reverse thread of the bidirectional screw and the sliding plate, combined with the guide limit of the slide rail and the slider. It can adapt to natural gas storage tanks of different diameters and lengths, solving the problem of fixed support spacing and poor adaptability of traditional devices, reducing equipment replacement costs and improving the versatility of the device.

[0016] 4. Comprehensive protection range, protecting key components: This utility model can achieve overall surround protection of the storage tank by cooperating with two sets of protective components, supporting arc plates and fixed arc plates. At the same time, the fixed cylinder protects the spring and the supporting plate protects the slide rail slider, preventing impurities from entering and affecting the function of the components. This solves the problem of incomplete protection range and exposure of key parts in traditional devices, and improves the durability of the device itself. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-4 As shown: This embodiment provides a protective device for transporting natural gas storage tanks, including a support 100. The support 100 is equipped with protective components 200, which are divided into two groups. A supporting arc plate 300 adapted to the outer wall of the storage tank is disposed between the two groups of protective components 200. The storage tank is located between the two groups of protective components 200 and rests on the supporting arc plate 300. The protective component 200 includes a supporting plate 210 disposed on the outside of the support 100. An elastic element 220 is disposed on the supporting plate 210. A vertical plate 230 is disposed on the upper part of the elastic element 220. An arc-shaped retaining plate 240 adapted to the outer wall of the storage tank is disposed on the upper part of the vertical plate 230. Specifically, the supporting arc plate 300 is made of 304 stainless steel, and its inner wall curvature is adapted to the outer wall of the storage tank. Two plates are provided and welded to the top of two sliding plates 103 respectively to support the weight of the storage tank. The retaining arc plate 400 is also made of 304 stainless steel. Made of stainless steel, the inner wall curvature is adapted to the outer wall of the storage tank. A pair of plates are welded to both ends of the vertical line where the midpoint of the support 100 is located, i.e., at the middle position of the support 100 between the two supporting arc plates 300. Together with the supporting arc plates 300, they form a ring-shaped fixation around the storage tank, enhancing stability. The vertical plate 230 is made of Q235 steel plate and is vertically welded to the upper part of the spring 222 for connecting the arc-shaped clamping plate 240; the arc-shaped clamping plate 240 is made of 304 stainless steel. Made of stainless steel, the inner wall conforms to the curvature of the outer wall of the natural gas storage tank. The arc-shaped clamping plate 240 is welded to the upper part of the vertical plate 230, and the highest point of the arc-shaped clamping plate 240 is less than or equal to the horizontal height of the axis of the storage tank after it is laid horizontally, ensuring that the storage tank can be laid horizontally stably and does not detach from the constraint of the arc-shaped clamping plate 240. This utility model can achieve a firm and stable support operation for the storage tank through the support arc plate 300 in conjunction with the arc-shaped clamping plate 240. The elastic element 220 facilitates the elastic support of the arc-shaped clamping plate 240, which can reduce the risk of the storage tank being bumped and scratched by the road surface during transportation, and greatly improve the safety performance during transportation.

[0021] According to one embodiment of the present invention, such as Figure 1-4 As shown, the support plate 210 is L-shaped. The horizontal part of the support plate 210 is welded to the outer wall of the bracket 100. The elastic element 220 is located on the upper part of the horizontal part of the support plate 210. The support plate 210 is made of Q235 steel plate. The horizontal part of the support plate 210 is fixed to the outer wall of the bracket 100 by bolts to provide stable support for the elastic element 220.

[0022] The elastic element 220 includes a fixed cylinder 221 disposed on the upper part of the horizontal section of the support plate 210, a spring 222 disposed inside the fixed cylinder 221, and a vertical plate 230 disposed on the upper part of the spring 222. The fixed cylinder 221 is made of 304 stainless steel and welded to the upper part of the horizontal section of the support plate 210. The inner wall is smooth to reduce friction. The spring 222 is made of 65Mn spring steel. The free length is adapted according to the specifications of the storage tank. One end of the spring 222 is welded to the bottom of the fixed cylinder 221, and the other end is connected to the vertical plate 230. It has good elastic restoring ability and can realize buffering and shock absorption. This utility model can realize the firm support of the storage tank between the various arc-shaped clamps 240 through the upward supporting force of the spring 222, the vertical plate 230, and the arc-shaped clamp 240. At the same time, it can also provide good buffering and shock absorption in bumpy transportation conditions and reduce mechanical wear.

[0023] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the support 100 includes a pair of slide rails 101, with sliders 102 slidably mounted at both ends of each slide rail 101. Slide plates 103 are respectively positioned between the two sliders 102 located on the same straight line as the two slide rails 101. The two slide plates 103 have threaded through holes with opposite threads, and bidirectional screws 104 are internally threaded into these through holes. Each slide plate 103 is equipped with a supporting arc plate 300. Specifically, the support 100 serves as the basic load-bearing structure of the device. The slide rails 101 are made of Q235 carbon structural steel, possessing good strength and toughness, and are set parallel to the load-bearing platform of the transport vehicle. The sliders 102 are made of 45# steel and are slidably fitted onto the slide rails 101, with a clearance fit to ensure smooth sliding. The slide plates 103 are made of Q235 steel. Made of steel plates, the tops of two sliders 102 are vertically welded to the same straight line, connecting the sliders 102 at corresponding positions on the two slide rails 101 with a connecting plate 103. Both sliding plates 103 have threaded through holes with opposite threads. The bidirectional screw 104 is made of 40Cr alloy structural steel with a galvanized anti-corrosion treatment. Its threaded section is adapted to the threaded through holes of the two sliding plates 103, and it passes through the two sliding plates 103 via a threaded connection, driving the sliding plates 103 to move in opposite directions along the slide rails 101. This invention allows the bidirectional screw 104 to rotate. Due to the threaded connection between the sliding plates 103 and the bidirectional screw 104, the guiding and limiting effect of the slide rails 101 on the sliders 102, and the fixing effect of the sliders 102 and sliding plates 103, the rotating bidirectional screw 104 drives the sliding plates 103 to slide along the slide rails 101. This facilitates adjustment of the distance between the supporting arc plates 300 on the two sliding plates 103, enabling secure support for storage tanks of different heights and enhancing its applicability.

[0024] There are two supporting arc plates 300, which are located at both ends of the bracket 100. A pair of fixed arc plates 400 are provided between the two supporting arc plates 300. The fixed arc plates 400 have through holes that are coaxial with the threaded holes on the slide plate 103. The diameter of the through holes is larger than the diameter of the threaded holes on the slide plate 103. The fixed arc plates 400 are located at both ends of the vertical line where the midpoint of the bracket 100 is located.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a force-applying component 105 is provided at the end of the bidirectional screw 104. The force-applying component 105 has an internal hexagonal screw hole. The force-applying component 105 is a hexagonal prism structure, made of No. 45 steel, and welded to the end of the bidirectional screw 104. The center of the force-applying component 105 has an internal hexagonal screw hole, which can be used with the DL2606 type internal hexagonal wrench produced by Zhejiang Deli Tools Co., Ltd. or the DCPB298 type internal hexagonal electric screwdriver produced by Jiangsu Dongcheng Electric Tools Co., Ltd., so as to facilitate the effortless rotation of the bidirectional screw 104. This utility model can achieve the rotation of the force-applying component 105 with the help of internal hexagonal electric tools or internal hexagonal wrenches.

[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the highest point of the arc-shaped pallet 240 is less than or equal to the horizontal height of the axis of the storage tank after it is laid horizontally, which facilitates the horizontal laying operation of the storage tank.

[0027] Working principle and usage of this utility model: First, it should be clarified that the protective device involved in this utility model is mainly used for supporting and protecting cylindrical objects during transportation. Taking the protection of natural gas storage tanks during transportation as an example, this utility model will explain its working principle and usage method in detail. The working principle is as follows: This utility model achieves adjustable support, cushioning and shock absorption, firm fixation, and comprehensive protection for natural gas storage tanks through the synergistic effect of its various components. The specific working principle is as follows: Adjustable support adapts to different storage tanks: When transporting storage tanks of different specifications, use an Allen wrench or an electric Allen screwdriver to insert into the Allen screw hole of the force-applying component 105 and rotate the bidirectional screw 104; since the bidirectional screw 104 and the threaded through holes of the two sliding plates 103 are connected by reverse threads, and the slider 102 slides and is limited on the slide rail 101, when the bidirectional screw 104 rotates, it will drive the two sliding plates 103 to move towards or away from each other along the slide rail 101, thereby adjusting the distance between the two support arc plates 300, so that the support arc plates 300 can fit the bottom of storage tanks of different diameters and lengths, realizing the adaptable support for storage tanks of different specifications, and solving the problem of the non-adjustable support spacing of traditional devices. Elastic buffer to prevent bumps and scratches: The storage tank is placed horizontally on the supporting arc plate 300 and the fixed arc plate 400, and the arc-shaped clamping plate 240 fits against the outer wall of the storage tank. When encountering bumpy roads during transportation, the vibration generated by the storage tank will be transmitted to the arc-shaped clamping plate 240. The arc-shaped clamping plate 240 pushes the vertical plate 230 downward to compress the spring 222. The spring 222 is compressed and undergoes elastic deformation, absorbing the vibration energy. At the same time, the fixed cylinder 221 limits the extension and contraction direction of the spring 222 to prevent the spring 222 from deviating. Through the elastic buffering effect of the spring 222, the rigid collision between the storage tank and the supporting components can be greatly reduced, preventing bumps and scratches on the outer wall of the storage tank, protecting the anti-corrosion layer of the storage tank, and solving the problem of insufficient buffering in traditional devices. Multi-arc plate coordinated fixation to prevent displacement: The supporting arc plate 300 bears the main weight of the storage tank, the fixed arc plate 400 constrains the storage tank from both sides of the middle, and the arc-shaped clamping plate 240 limits the storage tank laterally from both sides of the bracket 100. The three form a ring-shaped fixing structure. When the transport vehicle brakes suddenly or turns, the supporting arc plate 300 prevents the storage tank from sliding along the slide rail 101, and the fixed arc plate 400 and the arc-shaped clamping plate 240 prevent the storage tank from rotating or shifting laterally, ensuring that the storage tank always maintains a stable position during transportation and solving the problem of unstable fixation of traditional devices. Comprehensive protection covering key parts: Two sets of protective components 200 are symmetrically distributed on both sides of the support 100. The arc-shaped clamping plate 240 covers the outer walls of both sides of the storage tank, and the supporting arc plate 300 and the fixed arc plate 400 cover the bottom and middle outer walls of the storage tank, forming a surrounding protection for the entire storage tank. At the same time, the fixed cylinder 221 wraps the spring 222, which can prevent impurities from entering the gap of the spring 222 during transportation and affecting the elastic performance. The cooperation structure between the slide rail 101 and the slider 102 is also protected by the support plate 210 on the outside of the support 100 to prevent impurities from entering and affecting the sliding. This achieves comprehensive protection for the storage tank and the key components of the device itself, solving the problem of incomplete protection range of traditional devices. The usage method is as follows: The protective device of this utility model has clear usage steps and is easy to operate. The specific usage method is as follows: Installation and Spacing Adjustment: First, fix the slide rail 101 of the bracket 100 to the carrying platform of the transport vehicle with bolts, ensuring that the slide rail 101 is parallel and stable; according to the length and diameter of the natural gas storage tank to be transported, use an Allen wrench or an electric Allen screwdriver to insert into the Allen screw hole of the force application component 105, and turn the double-ended screw 104 clockwise or counterclockwise to drive the two slide plates 103 to move along the slide rail 101, adjust the distance between the two support arc plates 300 so that the spacing of the support arc plates 300 matches the length of the storage tank, and the inner wall of the support arc plates 300 can fit the curvature of the bottom of the storage tank. Tank Placement and Fixing Inspection: Slowly lay the natural gas storage tank horizontally on the two supporting arc plates 300, ensuring that the middle of the tank is aligned with the position of a pair of fixed arc plates 400, and that the inner wall of the fixed arc plates 400 is in contact with the outer wall of the middle of the tank; observe the position of the arc-shaped clamping plate 240, ensuring that the inner wall of the arc-shaped clamping plate 240 is in contact with the outer walls on both sides of the tank, and that the highest point of the arc-shaped clamping plate 240 does not exceed the axial height of the tank after it is laid horizontally; gently push the tank to check whether the supporting arc plates 300, fixed arc plates 400 and arc-shaped clamping plates 240 can effectively restrain the tank and that there is no obvious looseness. Transportation process monitoring: Before starting the transport vehicle, check again whether the double-ended screw 104 is tightened and whether each welded part is firm; during transportation, observe whether the storage tank has displacement or abnormal vibration through the vehicle monitoring system. If encountering severely bumpy road sections, reduce the vehicle speed appropriately to reduce the vibration amplitude of the storage tank. Device disassembly and maintenance: After transportation to the destination, use an Allen wrench to reverse the double-ended screw 104 to increase the distance between the two supporting arc plates 300, and slowly lift the storage tank off the device; clean the impurities from the inner walls of the supporting arc plate 300, the fixed arc plate 400, and the arc-shaped clamping plate 240; check the spring 222 for deformation or corrosion; if the spring 222's elasticity is weakened or damaged, replace it with a steel spring of the same specification; check the sliding performance of the slide rail 101 and the slider 102; if there is jamming, apply lubricating oil. 7019-1 extreme pressure industrial gear oil produced by Great Wall Lubricating Oil Co., Ltd. can be used to ensure smooth operation next time.

[0028] This utility model can achieve efficient and stable support for the storage tank through the elastic element 220 in conjunction with the support arc plate 300 and the arc-shaped clamping plate 240. It solves the problems of insufficient buffering and shock absorption, and easy collision and scratching of traditional transportation protection devices in practical applications: During transportation, road bumps will cause the storage tank to vibrate and shift. Traditional protection devices mostly use rigid support and lack elastic buffer structure. The storage tank and the support components directly contact and collide, which can easily cause collision and scratches on the outer wall of the storage tank, damage the anti-corrosion layer, shorten the service life of the storage tank, and may cause leakage risk in severe cases.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
