Description

Technical Field

[0001] This invention relates to the field of logistics transportation equipment technology, specifically to a vertical tank integrated transportation frame. Background Technology

[0002] In modern multimodal transport and supply chain systems involving road, sea, and rail, small vertical tanks, as flexible and standardized medium-sized bulk liquid containers, offer advantages such as small capacity and vertical storage, saving more floor space compared to horizontal tanks. They are widely used for the safe transfer of small batches of high-value liquids or liquids with special physicochemical properties. Currently, to ensure their stability and safety during transportation, there are two main solutions for mobile frame technology surrounding small vertical tanks.

[0003] The most common solution currently is to use a tail-mounted mobile frame based on standard container dimensions. During loading and unloading operations, individual small vertical tanks are transported into the frame's interior space through the tail opening using forklifts or other handling equipment. The tanks are then manually adjusted and secured using a combination of manual and mechanical methods. This process requires operators to enter the frame and, within a limited space, repeatedly intervene manually to move and lock the tanks to prevent displacement during transport. Each operation is performed individually, making batch or synchronized operations impossible. The entire process is cumbersome and relatively inefficient. Furthermore, due to the heavy reliance on manual intervention, there are inherent deviations in the positioning and securing of different tanks, making it difficult to guarantee locking reliability during transport, especially under the dynamic load conditions of shipping.

[0004] To overcome the shortcomings of tail-end loading and unloading methods, the industry has designed a top-lifting frame solution. The main frame is a three-dimensional enclosure structure with an open or operable top. Small vertical tanks are lifted as a whole using vertical lifting equipment such as cranes or gantry cranes and vertically placed into pre-designated container positions through an opening at the top of the frame. Personnel and equipment do not need to enter the frame for operation. However, loading and unloading operations heavily rely on fixed heavy-duty lifting equipment, placing high demands on the site infrastructure and making it unsuitable for all logistics nodes. Furthermore, the structural design of such frames often focuses on fulfilling loading and unloading functions, but the top structure or overall strength may not be conducive to safe and stable multi-layer stacking, thus affecting space utilization efficiency and hindering large-scale transportation. Especially during shipping, there is no flexibility compared to land transportation. Ships are continuously subjected to waves, wind loads, and other forces during navigation, resulting in multi-degree-of-freedom swaying, pitching, rolling, and periodic impacts. Existing solutions struggle to meet the comprehensive requirements of shipping for fixed reliability, displacement resistance, and space utilization.

[0005] Therefore, there is an urgent need for an integrated transportation framework that can be adapted to the loading, unloading, securing and transporting of small vertical tanks. Summary of the Invention

[0006] The purpose of this invention is to provide a vertical tank integrated transport frame to solve the above-mentioned problems.

[0007] The technical solution adopted in this invention is as follows:

[0008] A vertical tank integrated transport frame for loading and transporting vertical tanks, the vertical tank integrated transport frame including a transport frame and multiple movable frames; The conveying frame is a box-type frame including a top, bottom and side walls. Box inlets are respectively provided on the two side walls of the conveying frame that extend along the length direction. An isolation frame is provided between the box inlets on both sides. Multiple mounting positions are formed between the isolation frame and the box inlet on either side. Box inlet channels extending along the width direction of the conveying frame are respectively provided between the box inlet and each mounting position. The mobile frame is used to load vertical tanks. The mobile frame can enter or exit the installation position from the tank inlet along the tank inlet channel. The installation position corresponds one-to-one with the mobile frame. A locking structure is provided at the bottom of the conveying frame, which is used to cooperate with the moving frame to limit the position of the moving frame.

[0009] As a further improvement of the present invention, the locking structure includes a second locking tongue and a driving mechanism. The driving mechanism can drive the second locking tongue to rotate and move axially. The horizontal cross-section of the second locking tongue has a shape with a major axis and a minor axis. A slot is provided at a corresponding position at the bottom of the moving frame, and the slot cooperates with the second locking tongue. A sensing mechanism and a limiting member that changes state or position according to the signal of the sensing mechanism are provided in the mounting position. The limiting member can control the driving mechanism to maintain the initial state or enter the operating state. Before the moving frame is fully inserted into the mounting position, the limiting member restricts the drive mechanism to remain in its initial state. When the drive mechanism is in its initial state, the second locking tongue is away from the bottom of the moving frame. When the moving frame is fully inserted into the mounting position, the sensing mechanism is triggered, and the limiting member controls the drive mechanism to enter the operating state. When the drive mechanism is in the operating state, the drive mechanism drives the second locking tongue to move axially through the slot and then rotate. After rotation, the second locking tongue and the inner wall of the slot form an interference abutment in the width direction of the conveying frame to restrict the moving frame from exiting along the box entry channel.

[0010] As a further improved technical solution of the present invention, the driving mechanism includes a second base, a spring and a second rotating shaft. A second through hole extending vertically is provided in the second base, and the second rotating shaft passes through the second through hole. The second rotating shaft is connected to the second base by the spring. The second locking tongue is provided at the end of the second rotating shaft that extends out of the second through hole. A positioning protrusion is provided on the second rotating shaft, and a sliding groove is provided on the inner wall of the second through hole. The positioning protrusion is provided in the sliding groove and can slide along the sliding groove. The sliding groove includes a first groove segment and a second groove segment that are connected. The first groove segment extends axially, and the second groove segment is an arc-shaped groove that extends axially away from the first groove segment. The limiting member can restrict the axial position of the second rotating shaft or release the second rotating shaft. When the limiting member restricts the axial position of the second rotating shaft so that the spring is in a pre-compressed state, the drive mechanism remains in the initial state; when the limiting member releases the second rotating shaft, the drive mechanism is in the operating state.

[0011] As a further improvement of the present invention, a third groove segment is formed by extending axially away from the end of the second groove segment in a direction away from the first groove segment, and the length of the third groove segment is less than the axial length of the second groove segment.

[0012] As a further improvement of the present invention, the sensing mechanism is a proximity switch mounted on the conveying frame, and the limiting member is an electromagnetic locking pin mounted on the second base. The proximity switch and the electromagnetic locking pin are both electrically connected to a control unit. A slot that cooperates with the electromagnetic locking pin is provided on the second rotating shaft. When the electromagnetic locking pin is de-energized, the electromagnetic locking pin can be locked into the slot. When the moving frame is fully in the installation position, the proximity switch sends a signal to the control unit, and the control unit controls the electromagnetic locking pin to be energized, so that the electromagnetic locking pin exits the slot and releases the second rotating shaft.

[0013] As a further improvement of the present invention, a second handle is provided at the end of the second rotating shaft away from the second locking tongue, and the second handle extends radially along the second rotating shaft.

[0014] As a further improvement of the present invention, two rows of elastic guide members are arranged along the width direction of the conveying frame in the installation position, forming an inlet channel between the two rows of elastic guide members. The elastic guide members are arranged on the conveying frame and are used to guide the moving frame into the inlet channel.

[0015] As a further improvement of the present invention, the elastic guide is a rubber guide block. The side of the rubber guide block facing the adjacent mounting position includes a guide surface and a limiting surface arranged in sequence. The guide surface is arranged close to the adjacent box inlet, and the limiting surface is arranged away from the adjacent box inlet and smoothly connected to the guide surface. The limiting surfaces of the two opposing rubber guide blocks are in contact with the outer surface of the moving frame to limit the position of the moving frame in the length direction of the conveying frame. Along the box inlet direction, the distance between the two opposing guide surfaces gradually decreases until it is equal to the distance between the two opposing limiting surfaces.

[0016] As a further improvement of the present invention, at least two rubber guide blocks are provided on each side of each of the mounting positions.

[0017] As a further improvement of the present invention, two adjacent inlet channels share a row of rubber guide blocks located in the middle of them.

[0018] The beneficial effects of this invention are as follows: The above structure, employing a large conveyor frame and an independent mobile frame, simplifies the on-site loading and unloading process; the conventional tail-entry method is changed to side-entry, with multiple installation positions set along the length, shortening the loading and unloading path and eliminating the need to penetrate deep into the conveyor frame, thus improving operational efficiency and safety; a locking structure is added to fix the mobile frame, ensuring reliability and stability during land and sea transportation.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0022] If the description of this invention involves orientation (e.g., up, down, left, right, front, back, outside, inside, etc.), then the orientations involved need to be defined. For example, "To clearly express the positions and directions described in this invention, the operator of the device is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not necessary.

[0023] A vertical tank integrated transport frame, such as Figure 1 , 3 As shown, the vertical tank integrated transport frame is used to load and transport vertical tank 1. The vertical tank integrated transport frame includes a transport frame and multiple mobile frames 3. The mobile frames 3 are used to carry a single vertical tank 1. The transport frame 2 is used to carry and transport multiple mobile frames 3. After the vertical tank 1 is loaded, the mobile frames 3 are moved into the transport frame 2 for transport. The conveying frame 2 is a box-type frame including a top, a bottom, and side walls. The top of the conveying frame 2 includes multiple top crossbeams, multiple top longitudinal beams, and multiple inclined reinforcing beams. The bottom of the conveying frame 2 includes multiple bottom crossbeams, multiple bottom longitudinal beams, and multiple inclined reinforcing beams. The side walls of the conveying frame 2 include multiple side wall crossbeams, multiple side wall longitudinal beams, and multiple inclined reinforcing beams. The moving frame 3 is a box-type frame. The integrated transport frame breaks down the conventional transport frame into a large conveying frame 2 for transporting multiple vertical tanks 1 and multiple small mobile frames 3 for independently loading a single vertical tank 1. This allows the process of adjusting the posture of the vertical tank 1 to be transferred to the process of loading and unloading into the conveying frame 2, thus simplifying the loading and unloading process. like Figure 1 As shown, open box inlets are respectively provided on the two side walls of the conveying frame 2 extending along the length direction. An isolation frame 201 is provided between the box inlets on both sides. Multiple mounting positions 202 arranged along the length direction of the conveying frame 2 are formed between the isolation frame 201 and the box inlet on either side. The mounting positions 202 are used to accommodate the movable frame 3. A box inlet channel extending along the width direction of the conveying frame 2 is respectively provided between the box inlet and each mounting position 202. By adjusting the conventional tail inlet to the side wall along the length of the conveying frame 2, and in conjunction with the multiple mounting positions 202 arranged along the length, a single vertical tank 1 can directly enter the mounting position 202 from the length direction along with the moving frame 3, shortening the loading and unloading path. Since the mounting position 202 is close to the inlet, it is also convenient to operate and adjust without having to go deep into the transport frame, thus improving convenience. At the same time, the conveying frame 2 is divided into two independent spaces with a single-sided inlet, and the moving frame 3 can enter and exit from either side of the conveying frame 2 to load and unload the vertical tank 1 independently, simultaneously and without interference, making it easier to meet the size requirements of conventional transportation. In another embodiment, an inlet can be provided on one of the side walls extending along the length of the conveying frame 2. While the single-sided inlet is simpler and easier to manage the vertical tanks 1, it may lead to an excessively long conveying frame 2 when there are many vertical tanks 1, exceeding the load-bearing capacity of conventional transport vehicles. Therefore, it is suitable for scenarios with a small number of vertical tanks 1. The double-sided inlet solution provided in this embodiment shortens the length of the conveying frame 2. When carrying the same number of vertical tanks 1, the length of the double-sided conveying frame 2 is only about half that of the single-sided layout, resulting in higher loading and unloading efficiency and suitability for scenarios with a large number of vertical tanks 1. In practical applications, the choice between a single-sided or double-sided inlet solution is made based on the specific dimensions of the vertical tanks 1, the conveying frame 2, and the moving frame 3, or the dimensions of the conveying frame 2 and the moving frame 3 are designed according to the requirements of single-sided or double-sided inlet.

[0024] The "length direction of conveyor frame 2" is defined as: the extension direction of the longest sidewall of conveyor frame 2; the "sidewall extending along the length direction of conveyor frame 2" is defined as: the longest sidewall of conveyor frame 2; the "width direction of conveyor frame 2" is defined as: the horizontal direction perpendicular to the length direction of conveyor frame 2; the "height direction of conveyor frame 2" is defined as: the direction from the bottom to the top of conveyor frame 2; the direction of movement from the box inlet along the box inlet channel towards the mounting position 202 is defined as the "box inlet direction". To avoid lengthy statements, the "length direction" will be referred to as the length direction of conveyor frame 2, the "width direction" as the width direction of conveyor frame 2, and the "height direction" as the height direction of conveyor frame 2. like Figures 2-4 As shown, the movable frame 3 is used to load the vertical tank 1. The movable frame 3 has a positioning support structure inside that is adapted to the bottom / side wall of the vertical tank 1 to securely load the vertical tank 1 therein. The movable frame 3 can enter or exit the installation position 202 through the inlet channel. The installation position 202 corresponds one-to-one with the movable frame 3. That is, the movable frame 3 can be sent into the installation position 202 from the inlet of the conveying frame 2 along the inlet channel, thereby loading the vertical tank 1 into the conveying frame 2, or the movable frame 3 can be exited from the installation position 202 along the inlet channel, thereby unloading the vertical tank 1 from the conveying frame 2.

[0025] The conveying frame 2 is provided with a limiting and fixing structure at the corresponding installation position 202. The limiting and fixing structure is used to lock the moving frame 3 that enters the installation position 202, so as to restrict its movement within the conveying frame 2. This achieves quick and reliable fixing of the moving frame 3 within the conveying frame 2, effectively preventing the risk of displacement, shaking and collision during transportation.

[0026] A guide and limiting structure is provided at the bottom of the conveying frame 2 to cooperate with the inlet channel. This structure guides the movement of the moving frame 3 and restricts its horizontal position when it reaches the installation position 202. The guide and limiting structure ensures smooth and unobstructed linear movement of the moving frame 3 from the inlet to the installation position 202, reducing the intensity of manual pushing or the adjustment requirements during mechanical loading. Furthermore, the horizontal constraint on the moving frame 3 upon reaching the installation position 202 allows it to quickly and accurately align and fix with the limiting and fixing structure, simplifying the loading and unloading process.

[0027] It should be noted that the "moving frame 3" described in this invention is not limited to an independent frame structure. It can also be a support base, tray, or skirt structure that is integrated into the bottom of the vertical tank 1. As long as it has the feature of cooperating with the conveying frame 2 and the structure on it, it falls within the protection scope of this invention.

[0028] A locking structure 5 is provided at the bottom of the conveying frame 2. The locking structure 5 cooperates with the moving frame 3 to restrict the position of the moving frame 3 in the height and horizontal directions, thereby maintaining the stability of the moving frame 3 during the conveying process.

[0029] The locking structure 5 includes a locking tongue and a driving mechanism. The driving mechanism can drive the locking tongue to rotate around its axis and move along the axial direction. The horizontal cross-section of the locking tongue is a non-circular structure with directionality, that is, it has a major axis and a minor axis, such as a rectangle or an ellipse. A slot 301 is provided at the corresponding position at the bottom of the moving frame 3, and the slot 301 cooperates with the locking tongue.

[0030] In this embodiment, the bottom of the movable frame 3 includes a bottom surface 302 and a bottom plate 303. The bottom surface 302 is the surface where the lowest point of the movable frame 3 is located in the vertical direction, that is, the surface used to contact the bottom of the conveying frame 2. The slot 301 is provided on the bottom plate 303. There is a height difference between the bottom plate 303 and the bottom surface 302. The height difference is used to make way for the locking structure 5 and to provide space for the locking tongue to rise and fall.

[0031] This invention provides two embodiments of the locking structure 5. Among them, such as... Figure 5 , 6 The diagram shows a first embodiment of the locking structure 5 of the present invention.

[0032] One embodiment of the locking structure 5 includes a first base 5021, a first rotating shaft, and a first locking tongue 5011. A first through hole extending vertically is provided in the first base 5021. The first rotating shaft passes through the first through hole. The first locking tongue 5011 is provided at the end of the first rotating shaft that extends out of the first through hole. A first handle that rotates synchronously with the first rotating shaft is provided at the end of the first rotating shaft away from the first locking tongue 5011. The first handle and the first rotating shaft cooperate to form a driving mechanism. By rotating the first handle, the first rotating shaft and the first locking tongue 5011 located on the first rotating shaft can be driven to rotate synchronously around the axis of the first rotating shaft.

[0033] In the first embodiment, the movable frame 3 needs to be placed into the box using a lifting and lowering method. During the placement of the movable frame 3 into the box, it is gently lifted and fed along the box-entry channel above the mounting position 202. When the slot 301 is above the first locking tongue 5011, the movable frame 3 is lowered so that the first locking tongue 5011 is inserted into the slot 301. Therefore, sufficient lifting space needs to be provided in the height direction of the mounting position 202; that is, the height of the mounting position 202 needs to be at least greater than the sum of the heights of the movable frame 3 and the first locking tongue 5011, so that the movable frame 3 can be lifted and lowered from above. Before locking, the spatial orientation of the first locking tongue 5011 matches the shape of the slot 301 to facilitate entry into the slot 301. After the moving frame 3 moves down into place, the first locking tongue 5011 completely passes through the slot 301. At this time, rotating the first handle changes the spatial orientation of the first locking tongue 5011, causing the first locking tongue 5011 to interfere with the inner wall of the slot 301 and become unable to exit the slot 301.

[0034] like Figures 7-11 The diagram shows a second embodiment of the locking structure 5 described in this invention.

[0035] In the second embodiment, the locking structure 5 includes a second locking tongue 5012 and a driving mechanism. A sensing mechanism and a limiting member that changes state or position according to the signal of the sensing mechanism are provided in the mounting position 202. The limiting member can control the driving mechanism to maintain the initial state or enter the operating state. Before the movable frame 3 is fully inserted into the mounting position 202, the limiting member restricts the drive mechanism to remain in its initial state. When the drive mechanism is in its initial state, the second locking tongue 5012 is away from the bottom of the movable frame 3. When the movable frame 3 is fully inserted into the mounting position 202, the sensing mechanism is triggered, and the limiting member controls the drive mechanism to enter the operating state. When the drive mechanism is in the operating state, the drive mechanism drives the second locking tongue 5012 to move axially through the slot 301 and then rotate. After rotation, the second locking tongue 5012 and the inner wall of the slot 301 form an interference abutment in the width direction of the conveying frame 2 to restrict the movable frame 3 from exiting along the box entry channel. Thus, automatic locking can be achieved after the movable frame 3 is moved into the mounting position 202, realizing the limiting and fixing between the movable frame 3 and the conveying frame 2.

[0036] The second embodiment of the locking structure 5, through the cooperation of the sensing mechanism and the limiting component, can automatically lock and limit the moving frame 3 and the conveying frame 2 after the moving frame 3 is moved into the installation position 202. It has a high degree of automation and eliminates the need for conventional locking operations.

[0037] As an embodiment of the driving mechanism in the second embodiment of the locking structure 5 of the present invention, the driving mechanism includes a second base 5022, a spring 503 and a second rotating shaft 504. A second through hole 5023 extending vertically is provided in the second base 5022. The second rotating shaft 504 passes through the second through hole 5023 and is connected to the second base 5022 by the spring 503. A second locking tongue 5012 is provided at the end of the second rotating shaft 504 that extends out of the second through hole 5023. A positioning protrusion 505 is provided on the second rotating shaft 504. A sliding groove 506 is provided on the inner wall of the second through hole 5023. The positioning protrusion 505 is provided in the sliding groove 506 and can slide along the sliding groove 506. The sliding groove 506 includes a first groove segment 5061 and a second groove segment 5062 that are connected. The first groove segment 5061 extends axially, and the second groove segment 5062 is an arc-shaped groove that extends axially away from the first groove segment 5061. The limiting member can restrict or release the axial position of the second rotating shaft 504. When the limiting member restricts the axial position of the second rotating shaft 504 so that the spring 503 is in a pre-compressed state, the drive mechanism remains in its initial state, the positioning protrusion 505 is located in the first groove 5061, and the second locking tongue 5012 does not contact the moving frame 3. When the limiting member releases the second rotating shaft 504, the drive mechanism is in operation, and the positioning protrusion 505 slides along the first groove 5061 into the second groove 5062. At this time, the second locking tongue 5012 has passed through the slot 301. Subsequently, the positioning protrusion 505 makes a spiral upward movement along the second groove 5062. That is, the positioning protrusion 505 rotates at a certain angle during the upward movement, and the second locking tongue 5012 rotates at a certain angle to interfere with the slot 301.

[0038] Specifically, the angle between the projections of the two ends of the second groove segment 5062 onto the axial direction of the second rotating shaft 504 is α, where 0° < α < 180°, and preferably α is 90°.

[0039] Furthermore, a third groove segment 5063 extends axially away from the end of the second groove segment 5062, away from the first groove segment 5061. The length of the third groove segment 5063 is less than the axial length of the second groove segment 5062. The third groove segment 5063 is a groove segment with a shorter axial length. The third groove segment 5063 is used to provide tolerance space for the second locking tongue 5012. Since the second locking tongue 5012 is driven by the spring 503, it may get stuck due to manufacturing assembly deviations or slight deformation during locking or unlocking. By adding the third groove segment 5063, the spring force can reliably push the second locking tongue 5012 to the set position, achieving stable locking or unlocking and ensuring the reliability of the locking or unlocking action.

[0040] Furthermore, a baffle 508 is provided at the bottom of the second base 5022, and a third through hole is provided on the baffle 508. The diameter of the third through hole is smaller than that of the second through hole 5023 and larger than that of the second rotating shaft 504. A limiting step 5041 is provided on the second rotating shaft 504. One end of the spring 503 is connected to the limiting step 5041 and the other end is connected to the baffle 508.

[0041] Furthermore, a receiving groove 5024 is provided in the second base 5022. The receiving groove 5024 extends from the upper surface of the second base 5022 into the interior of the second base 5022. In the initial state, the second locking tongue 5012 is located in the receiving groove 5024 to avoid collision with the moving frame 3 during the box loading process.

[0042] As an embodiment of the sensing mechanism and limiting member of the locking structure 5 of the present invention, the sensing mechanism is a proximity switch 6 disposed on the conveying frame 2, and the limiting member is an electromagnetic locking pin 7 disposed on the second base 5022. The proximity switch 6 and the electromagnetic locking pin 7 are both electrically connected to a control unit. A slot 507 that cooperates with the electromagnetic locking pin 7 is provided on the second rotating shaft 504. When the electromagnetic locking pin 7 is de-energized, the electromagnetic locking pin 7 can be locked into the slot 507. When the moving frame 3 is fully inserted into the mounting position 202, the proximity switch 6 sends a signal to the control unit, and the control unit controls the electromagnetic locking pin 7 to be energized, and the electromagnetic locking pin 7 exits the slot 507 to release the second rotating shaft 504.

[0043] Furthermore, a second handle 509 is provided at the end of the second rotating shaft 504 away from the second locking tongue 5012, rotating synchronously with the second rotating shaft 504. The second handle 509 extends radially along the second rotating shaft 504. When it is necessary to remove the movable frame 3, force can be applied to the second handle 509 to cause the second rotating shaft 504 to rotate in the opposite direction. This reverse rotation refers to the opposite movement to the spiral upward movement of the aforementioned positioning protrusion 505, that is, the movement of the second rotating shaft 504 corresponding to the spiral downward movement of the positioning protrusion 505. After the second rotating shaft 504 reverses, the second locking tongue 5012 also rotates accordingly, exiting the slot 301 and moving away from the movable frame 3, thereby unlocking the movable frame 3 from the conveying frame 2. Subsequently, the movable frame 3 can be removed from the conveying frame 2.

[0044] Furthermore, during use, an insertion hole can be provided on the second rotating shaft 504, which cooperates with the second handle 509. Thus, when the moving frame 3 is installed, the second handle 509 does not need to be inserted into the insertion hole. When the moving frame 3 is removed, the second handle 509 is then inserted into the insertion hole to separate the moving frame 3 from the conveying frame 2.

[0045] Through the second embodiment of the locking structure 5 and its corresponding sensing mechanism and limiting component, the loading and unloading of the movable frame 3 can be made more convenient and the degree of automation is higher. When this structure is adopted, it can be lifted and pushed by a forklift or transported by electric equipment. During the process of the movable frame 3 sliding into the mounting position 202 along the box inlet channel, the movable frame 3 can be directly and automatically locked with the conveying frame 2. As an embodiment of the present invention, the locking tongue (both the first locking tongue 5011 and the second locking tongue 5012) is provided with a guide slope 5013 to facilitate smoother insertion into the slot 301.

[0046] As an embodiment of the present invention, at least two locking structures 5 are arranged along the length of the conveying frame 2 within the mounting position 202 to enhance the limiting ability and holding force, and maintain the stability of the moving frame 3 during the conveying process.

[0047] As one embodiment of the present invention, such as Figure 1 As shown, two rows of elastic guide members are arranged along the width direction of the conveying frame 2 in the installation position 202, forming an inlet channel between the two rows of elastic guide members. The elastic guide members are set on the conveying frame 2 and are used to guide the movement of the moving frame 3, guiding the moving frame 3 into the inlet channel to prevent deviation. Moreover, the elastic structure can avoid rigid collisions and wear of the moving frame 3 during the entry and exit process.

[0048] In this embodiment, the elastic guide can be a rubber structure, an airbag structure, or a magnetic structure for positioning and guidance, as long as it can meet the requirements of guidance, initial limiting, and flexible contact.

[0049] As a preferred embodiment of the present invention, such as Figure 12 As shown, the elastic guide is a rubber guide block 4. The side of the rubber guide block 4 facing the adjacent mounting position 202 includes a guide surface 401 and a limiting surface 402. The guide surface 401 is located near the inlet, while the limiting surface 402 is located away from the inlet and smoothly connected to the guide surface 401. When the moving frame 3 is moved into position, the limiting surfaces 402 of the two opposing rubber guide blocks 4 abut against the outer surface of the moving frame 3 to limit the position of the moving frame 3 along the length of the conveying frame 2, thus initially positioning the moving frame 3. Simultaneously, due to the elasticity and deformation allowance of the rubber material, the effective distance between the two opposing limiting surfaces 402 can accommodate moving frames 3 of different sizes within a certain range, thereby improving compatibility with various specifications of the moving frame 3. Along the inlet direction, the guide surfaces 401 and 402 of the two opposing rubber guide blocks 4... The spacing between the guide surfaces 401 of the two opposing rubber guide blocks 4 near the entrance of the box is gradually reduced until it is equal to the spacing between the two opposing limiting surfaces 402. In other words, the spacing between the guide surfaces 401 of the two opposing rubber guide blocks 4 near the entrance of the box is large, thus relaxing the width restriction of the moving frame 3 entering the box passage, allowing the moving frame 3 to enter comfortably and smoothly. The spacing between the guide surfaces 401 of the two opposing rubber guide blocks 4 near the limiting surface 402 is small, and the spacing gradually decreases as the moving frame 3 moves deeper, causing the moving frame 3 to gradually center and be gradually confined between the two opposing limiting surfaces 402. Specifically, the guide surface 401 is an inclined surface or an arc surface.

[0050] Specifically, at least two rubber guide blocks 4 are provided on each side of each mounting position 202, arranged along the width direction of the conveying frame 2. The combined action of multiple rubber guide blocks 4 can provide a more continuous and stable guiding effect. In addition, multiple limiting surfaces 402 are provided on one side of the moving frame 3. The combined action of multiple limiting surfaces 402 can provide a more reliable limiting effect, avoiding displacement of the moving frame 3 due to vibration, bumps, etc. during the conveying process when only a single limiting surface 402 is used, thus improving the stability and safety of the positioning.

[0051] Furthermore, in order to further improve space utilization, two adjacent inlet channels share a row of rubber guide blocks 4 located in the middle of them. Both sides of the rubber guide blocks 4 are provided with guide surfaces 401 and limiting surfaces 402, which can be used by both sides for inlet channels at the same time. While not affecting the limiting and guiding effect of a single inlet channel, the overall structure of the conveying frame 2 is more compact and cost-saving.

[0052] Furthermore, such as Figure 5 , 7 As shown, when the locking structure 5 adopts the scheme of Embodiment 1, since this embodiment requires lifting the movable frame 3 to lock with the locking structure 5, the upper surface of the rubber guide block 4 needs to be higher than the upper surface of the first locking tongue 5011. This is to avoid the side wall of the movable frame 3 separating from the limiting surface 402 of the rubber guide block 4 during the lifting of the movable frame 3, thus losing the limiting and guiding effect, or to avoid the need to lift the movable frame 3 again during the locking operation, so that it can be put into the box in one go. When the locking structure 5 adopts the scheme of Embodiment 2, a guide beam 203 is provided in the conveying frame 2 to support the weight of the movable frame 3 during the box entry process. After lifting the movable frame 3, the movable frame 3 is placed on the upper surface of the guide beam 203 and sent into the installation position 202. Therefore, there are no restrictions on the height of the rubber guide block 4. The rubber guide block 4 only needs to be higher than or placed on the guide beam 203.

[0053] In one embodiment of the present invention, a clamping structure for limiting the axial position of the moving frame 3 is provided on the conveying frame 2. The clamping structure can be incorporated into the aforementioned limiting and fixing structure. Specifically, the clamping structure is a clamping bolt provided on the top of the conveying frame 2.

[0054] As one embodiment of the present invention, such as Figure 1 , 13As shown, standardized top corner pieces 204 are provided at the four corners of the top of the conveying frame 2, and standardized bottom corner pieces 205 are provided at the four corners of the bottom of the conveying frame 2. The top corner pieces 204 and bottom corner pieces 205 are mutually cooperating concave-convex stacking structures. In this embodiment, the top corner piece 204 adopts a groove structure, and the bottom corner piece 205 adopts a protruding structure. The protrusion of the bottom corner piece 205 can be inserted into the groove of the top corner piece 204. The two cooperate with each other to realize the vertical stacking and positioning of multiple conveying frames 2, resulting in high space utilization. The external dimensions of the conveying frame 2 and the spatial distribution and spacing of the top corner pieces 204 and bottom corner pieces 205 conform to the standard container specifications, enabling the vertical tank 1 integrated transport frame to be mixed and stacked with standard containers or loaded and unloaded using general container spreaders.

[0055] As an embodiment of the present invention, a reinforcing plate 206 is provided at the connection between the isolation frame 201 and the conveying frame 2 to enhance the connection strength between the two and ensure the stability and reliability of the overall structure during load and transportation.

[0056] The vertical tank 1 integrated transport frame provided by this invention adopts a modular design, disassembling the traditional integral transport frame into a large conveying frame 2 and an independent moving frame 3. This allows the posture adjustment and fixing processes of the vertical tank 1 to be moved forward, simplifying the on-site loading and unloading process on the transport vehicle. By changing the conventional rear-entry box to a side-entry box and setting multiple installation positions 202 along the length direction, the loading and unloading path of each vertical tank 1 is shortened to a short-distance straight movement, without needing to go deep into the conveying frame 2, improving work efficiency and operational safety. The setting of box entry from both sides shortens the length of the conveying frame 2, improving the overall structure's compatibility with existing conveying equipment. The rubber guide block 4 and locking structure 5 work together to reliably limit the entry and positioning of the moving frame 3 from all directions, providing good resistance to lateral displacement. The automatic locking structure 5 and its cooperating sensing mechanism and limiting components eliminate the need for conventional locking operations, ensuring reliability and stability during land and sea transportation, and improving the efficiency of transport assembly. The internal layout is expandable and highly flexible.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.

All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
