Description

Technical Field

[0001] This invention belongs to the field of shipping container securing technology, and in particular relates to a container non-displacement lashing device and its application method. Background Technology

[0002] As a standardized transport carrier, containers have been widely used in many fields such as modern logistics, special equipment transport, and precision scientific research equipment transport. The reliability of the binding and fixing between the container and the support base directly determines the safety of the transportation process and the stability of the transported equipment.

[0003] Currently, the industry's conventional methods for securing containers to their mounting bases primarily employ traditional fasteners such as manual locks, semi-automatic locks, fully automatic locks, and fully automatic cones. These fasteners achieve locking by engaging with the corner fitting holes of the container; their core principle is to use a mechanical structure to constrain the container to the base. However, according to existing standards and classification society specifications, there are assembly gaps between the corner fitting holes and the fasteners. This results in a certain degree of displacement of the container in three spatial directions: under the influence of shipboard turbulence, sudden stops and accelerations, or wind and wave loads, the container will shift to a certain extent longitudinally, laterally, and vertically, making it impossible to achieve a completely displacement-free binding with the base.

[0004] While this type of lashing method with gaps can meet the industry standards and safety requirements for general freight containers, it has significant limitations in special high-precision application scenarios and can no longer meet the special needs of the market.

[0005] 1. Precision scientific research equipment transportation scenario: When high-precision scientific research instruments (such as gravity measuring instruments, earthquake monitoring equipment, optical experimental devices, etc.) are carried in containers, even a relative displacement of millimeters may cause the core components of the instrument to shift, the optical path to become misaligned, or the zero point of the sensor to drift, which may lead to equipment failure, data distortion, or even directly cause the failure of scientific research projects, resulting in incalculable economic and scientific research losses.

[0006] 2. Special Equipment Stabilization Scenarios: In scenarios such as marine scientific research, emergency communications, and military reconnaissance, containers need to be used as stable operating platforms, requiring them to maintain absolute positional and attitude stability relative to the ship's base. Any displacement will lead to platform attitude deviations, affecting operational accuracy and equipment safety, and may even cause safety accidents.

[0007] 3. Transportation of high-value precision equipment: For high-value goods such as aerospace parts, precision medical equipment, and semiconductor devices, even minor vibrations and displacements during transportation can cause damage to components, affecting product precision and service life, and bringing huge asset risks.

[0008] Currently, the market lacks a binding solution that can achieve zero displacement and zero gap between containers and their supporting bases. The displacement defects of traditional fasteners have become a key bottleneck restricting the development of high-precision mounting. Therefore, developing a binding solution and product that can achieve zero displacement of containers on the base is an urgent need to ensure equipment safety, data reliability, and operational stability in special scenarios, and it is also a core technical problem that urgently needs to be solved in this field. Summary of the Invention

[0009] The main objective of this invention is to propose a container non-displacement lashing device and its application method, which can effectively solve the problems in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A container non-displacement lashing device includes four single-unit bases;

[0012] The single-unit base includes a first support, a first panel, a first cone, a first eye plate, and a second eye plate. The first panel is fixed on the first support, and the first cone, the first eye plate, and the second eye plate are fixed on the upper surface of the first panel. The first cone is used to insert into the bottom hole of the container corner fitting. A first screw is threaded into the first eye plate, and a second screw is threaded into the second eye plate. The first screw and the second screw are arranged perpendicular to each other and are used to press against the lateral and longitudinal sides of the container corner fitting.

[0013] The single-unit base also includes a first vertical locking mechanism, which includes a first lock head, a first stop block, and a third screw. The first lock head is located above the first panel, and its head end is used to insert into the side hole of the container corner fitting. The first stop block is located below the first panel. The tail of the first lock head and the first panel have corresponding through holes for the third screw to pass through. The lower part of the third screw is provided with a threaded section that is threadedly connected to the first stop block, and the upper part has a first pressing part that presses against the upper surface of the first lock head.

[0014] Preferably, the first support base includes a first base substrate, a first support plate, a second support plate, a third support plate, and a fourth support plate. The first support plate, the second support plate, the third support plate, and the fourth support plate are fixed to the upper surface of the first base substrate and connected to each other to form a box-shaped structure. The first panel is fixed to the top of the first support plate, the second support plate, the third support plate, and the fourth support plate.

[0015] Preferably, it also includes at least two double bases and at least two support members;

[0016] The double-jointed base includes a second support base, a second panel, two second cones, a third eye plate, and a fourth eye plate. The second panel is fixed on the second support base, and the second cones, the third eye plate, and the fourth eye plate are fixed on the upper surface of the second panel. The second cones are used to insert into the bottom holes of the container corner fittings. A fourth screw is threaded into the third eye plate, and a fifth screw is threaded into the fourth eye plate. The fourth and fifth screws are arranged in parallel and are used to press against the longitudinal sides of the adjacent corner fittings of the two containers.

[0017] The double base also includes two second vertical locking mechanisms. Each second vertical locking mechanism includes a second lock head, a second stop block, and a sixth screw. The second lock head is located above the second panel, and its head end is used to insert into the longitudinal side holes of the two adjacent end corner fittings of the container. The second stop block is located below the second panel. The tail of the second lock head and the second panel have corresponding through holes for the sixth screw to pass through. The lower part of the sixth screw is provided with a threaded section that is threadedly connected to the second stop block, and the upper part has a second pressing part that presses against the upper surface of the second lock head.

[0018] The support includes a first base, a second base, and a double-ended screw. The threaded sections at both ends of the double-ended screw are threadedly connected to the first base and the second base, respectively. Rotating the double-ended screw can control the first base and the second base to move closer to or further away from each other. When they move away from each other, they are used to press against the lateral sides of the adjacent corner pieces of the two containers.

[0019] Preferably, the outer sides of the first base and the second base have positioning blocks for inserting into the lateral side holes of the container corner fittings.

[0020] Preferably, the second support base includes a second base substrate, a fifth support plate, a sixth support plate, a seventh support plate, and an eighth support plate. The fifth support plate, the sixth support plate, the seventh support plate, and the eighth support plate are fixed to the upper surface of the second base substrate and connected to each other to form a box-shaped structure. The second panel is fixed to the top of the fifth support plate, the sixth support plate, the seventh support plate, and the eighth support plate.

[0021] Preferably, the box-shaped structure has internal reinforcing ribs.

[0022] Preferably, a handle is fixedly connected to the first screw, the second screw, the third screw, the fourth screw, the fifth screw, the sixth screw, and the double-ended screw.

[0023] The present invention also provides a method for applying the above-mentioned container non-displacement lashing device, comprising the following steps:

[0024] S1. Base installation and positioning: The four single bases are firmly fixed to the bearing plane by welding or bolting according to the positions of the four corner pieces at the bottom of the container, forming a stable four-point bearing reference, ensuring that the position of the single bases corresponds precisely to the corner pieces of the container.

[0025] S2. Container positioning guidance: The container is hoisted to the top of the four single-unit bases and slowly lowered so that the bottom holes of the four corner pieces of the container are aligned with the first cones on the four single-unit bases. The bottom hole walls of the corner pieces automatically slide into place along the inclined surface of the first cone, completing the initial positioning of the container.

[0026] S3. Longitudinal freedom limit: Rotate the first screw to make the end of the first screw press against the lateral side of the container corner fitting, that is, the longitudinal position of the container is completely locked by the screw tightening force, thus restricting the longitudinal displacement of the container.

[0027] S4. Lateral freedom limit: Rotate the second screw to make the end of the second screw press against the longitudinal side of the container corner piece, that is, the lateral position of the container is completely locked by the screw tightening force, thus restricting the lateral displacement of the container.

[0028] S5. Vertical freedom limit: Insert the head of the first lock into the side hole of the container corner fitting, pass the third screw through the tail of the first lock and the first panel, then connect the first stop to the threaded section of the third screw and press it against the lower surface of the first panel, then rotate the third screw, the first pressing part presses down on the first lock, so that the first lock tightly locks the side hole of the corner fitting, and the container is completely pressed vertically by the cooperation of the first lock and the first stop, thus limiting the vertical jump and displacement of the container;

[0029] S6. Full constraint completed: The four corners of the container are constrained in three dimensions in the longitudinal, lateral and vertical directions through the above steps. Under the combined action of the four single-unit bases, all three degrees of freedom are restricted, achieving absolute fixation of the single container without displacement.

[0030] The present invention also provides a method for applying the above-mentioned container non-displacement lashing device, comprising the following steps:

[0031] S1. Base installation and positioning: Install two double bases at the adjacent corner joints of the two containers, and then install four single bases at the four outer corners of the two containers.

[0032] S2. Double container placement guide: Hoist the two containers to the top of the base respectively, and slowly lower them so that the bottom holes of the container corner fittings are aligned with the first cone of the single base and the second cone of the double base. The corner fittings will automatically slide into place along the inclined surface of the cone, completing the initial positioning of the double containers.

[0033] S3. Single-unit base limit: Repeat the single-unit binding mode operation for the four single-unit bases at the outer ends of the two containers to limit the longitudinal, lateral and vertical displacement of the containers respectively.

[0034] S4. Double base limit:

[0035] S41. Lateral limit: Rotate the fourth and fifth screws to simultaneously press the screw ends against the longitudinal side of the container corner fittings, locking the lateral displacement of the two containers;

[0036] S42. Vertical limit: Using the same operating method as the first vertical locking mechanism, the corner pieces at the adjacent ends of the two containers are vertically locked by two second vertical locking mechanisms to limit the vertical displacement of the two containers;

[0037] S5. Support component limiting: Two support components are installed between the corner pieces of the two adjacent ends of the containers. The first base of the two support components is inserted between the corner pieces of the two adjacent ends of the containers. The double-ended screw is rotated so that the first base is moved away from each other and clamps the lateral side of the corner pieces of the two adjacent ends of the containers. The longitudinal relative displacement of the two containers is limited by the bidirectional clamping force, which supplements the longitudinal constraint in the middle position.

[0038] S6. Fully constrained: Under the synergistic action of the single-unit base, double-unit base, and support components, the two containers are completely constrained in the longitudinal, lateral, and vertical directions, with no gaps or displacement space, achieving absolute fixation of the two containers without displacement.

[0039] This invention provides a container non-displacement lashing device and its application method, which has the following beneficial effects:

[0040] 1. Compared with traditional tie-down devices such as twist locks and bottom cones, this invention does not use clearance fit locking from the bottom hole of the corner piece. Instead, it achieves displacement-free fixation through a three-dimensional fully enclosed constraint method of tightening with transverse screws, longitudinal screws, and vertical locking mechanism. This ensures that the container does not move under unstable conditions such as dynamic impact and shaking, and guarantees the operating accuracy of internal equipment. It can meet the stringent requirements of high-precision equipment mounting and dynamic operation.

[0041] 2. This invention supports independent binding of a single box and parallel binding of two boxes, which can be flexibly adapted to different operating scenarios. Furthermore, with the addition of double bases and support components, it can also support parallel binding of three or more boxes, which is also within the scope of protection of this invention. The core components of this invention are divided into three categories: single base, double base, and support components. Standardized modules can be quickly assembled and replaced.

[0060] Example 1

[0061] This embodiment uses a single-box binding method.

[0062] Reference Figure 1The present invention provides a container non-displacement lashing device, including four single-unit bases 10. The single-unit base 10 is the basic unit for realizing single-point constraint of the container. In the single-container lashing mode, the container adopts a four-corner independent base support structure. The four corner pieces 1 at the bottom of the container form a complete four-point bearing frame with the four single-unit bases 10 respectively. Under the lashing action of the four single-unit bases 10, the container is completely fixed.

[0063] Reference Figure 2 , Figure 3 The single-unit base 10 includes a first support 101, a first panel 102, a first cone 103, a first eye plate 104, and a second eye plate 105. The first panel 102 is fixed on the first support 101. The first cone 103, the first eye plate 104, and the second eye plate 105 are fixed on the upper surface of the first panel 102. The first cone 103 is used to insert into the bottom hole of the container corner piece 1. A first screw 106 is threaded into the first eye plate 104, and a second screw 107 is threaded into the second eye plate 105. The first screw 106 and the second screw 107 are arranged perpendicular to each other and are used to press against the lateral side 11 and the longitudinal side 12 of the container corner piece 1.

[0064] Reference Figure 2 , Figure 4 The single-unit base 10 further includes a first vertical locking mechanism 108, which includes a first lock head 1081, a first stop block 1082, and a third screw 1083. The first lock head 1081 is located above the first panel 102, and its head end is used to insert into the side hole of the container corner piece 1. The first stop block 1082 is located below the first panel 102. The tail of the first lock head 1081 and the first panel 102 have corresponding through holes for the third screw 1083 to pass through. The lower part of the third screw 1083 is provided with a threaded section that is threadedly connected to the first stop block 1082, and the upper part has a first pressing part 1084 that is pressed against the upper surface of the first lock head 1081.

[0065] The container non-displacement lashing device of this embodiment includes the following steps when in use:

[0066] S1. Base installation and positioning: The four single bases 10 are firmly fixed to the bearing plane by welding or bolting according to the positions of the four corner pieces 1 at the bottom of the container, forming a stable four-point bearing reference, ensuring that the position of the single base 10 corresponds precisely to the container corner piece 1.

[0067] S2. Container placement guidance: The container is hoisted to the top of the four single-unit bases 10 and slowly lowered so that the bottom holes of the four corner pieces 1 at the bottom of the container are aligned with the first cones 103 on the four single-unit bases 10 respectively. The bottom hole wall of the corner piece 1 automatically slides into place along the inclined surface of the first cone 103, completing the initial positioning of the container.

[0068] S3. Longitudinal freedom limit: Rotate the first screw 106 so that the end of the first screw 106 presses against the lateral side 11 of the container corner piece 1, that is, the longitudinal position of the container is completely locked by the screw tightening force, thus restricting the longitudinal displacement of the container.

[0069] S4. Lateral freedom limit: Rotate the second screw 107 so that the end of the second screw 107 presses against the longitudinal side 12 of the container corner piece 1, that is, the lateral position of the container is completely locked by the threaded tightening force, thus restricting the lateral displacement of the container.

[0070] S5. Vertical freedom limit: Insert the head of the first lock head 1081 into the side hole of the container corner fitting 1, pass the third screw 1083 through the tail of the first lock head 1081 and the first panel 102, then connect the first stop 1082 with the threaded section of the third screw 1083 and press it against the lower surface of the first panel 102, then rotate the third screw 1083, and the first pressing part 1084 presses down on the first lock head 1081, so that the first lock head 1081 tightly locks the side hole of the corner fitting 1. Through the cooperation of the first lock head 1081 and the first stop 1082, the container is completely pressed vertically, limiting the vertical jump and displacement of the container.

[0071] In this embodiment, the first vertical locking mechanism 108 can be placed alongside the first eye plate 104 or alongside the second eye plate 105. That is, the first lock head 1081 can restrict the lateral side hole of the container corner piece 1 or restrict the longitudinal side hole of the container corner piece 1, depending on the specific needs.

[0072] S6. Full constraint completed: The four corners of the container are constrained in three dimensions in the longitudinal, lateral and vertical directions through the above steps. Under the combined action of the four single-unit bases 10, all three degrees of freedom are restricted, achieving absolute fixation of the single container without displacement.

[0073] As a preferred implementation scheme, refer to Figure 2The first support base 101 includes a first base plate 1011, a first support plate 1012, a second support plate 1013, a third support plate 1014, and a fourth support plate 1015. The first support plate 1012, the second support plate 1013, the third support plate 1014, and the fourth support plate 1015 are fixed to the upper surface of the first base plate 1011 and are connected to each other to form a box-shaped structure. The box-shaped structure has excellent bending and shear resistance and can withstand the heavy load and dynamic impact load of the container. The first panel 102 is fixed to the top of the first support plate 1012, the second support plate 1013, the third support plate 1014, and the fourth support plate 1015.

[0074] Example 2

[0075] This embodiment uses a double-box binding mode.

[0076] Reference Figure 5 Based on Embodiment 1, the present invention further includes two double-linked bases 20 and two support members 30. In the double-container binding mode, the two containers are placed side by side along the length direction. The four corner pieces 1 on the outer sides of both ends of the double-container are fixed to the four single-linked bases 10 respectively. The corner pieces 1 at adjacent ends form a load-bearing frame of "independent support at both ends and common support in the middle" by using two double-linked bases 20 and two support members 30. Under the action of the four single-linked bases 10, two double-linked bases 20 and two support members 30, the two containers are completely fixed.

[0077] Reference Figure 6 , Figure 7 The double-jointed base 20 includes a second support 201, a second panel 202, two second cones 203, a third eye plate 204, and a fourth eye plate 205. The second panel 202 is fixed on the second support 201. The second cones 203, the third eye plate 204, and the fourth eye plate 205 are fixed on the upper surface of the second panel 202. The second cones 203 are used to insert into the bottom hole of the container corner piece 1. A fourth screw 206 is threaded into the third eye plate 204, and a fifth screw 207 is threaded into the fourth eye plate 205. The fourth screw 206 and the fifth screw 207 are arranged in parallel and are used to press against the longitudinal side 12 of the two adjacent end corner pieces 1 of the container.

[0078] Reference Figure 6 , Figure 8The double base 20 also includes two second vertical locking mechanisms 208. The second vertical locking mechanism 208 includes a second lock head 2081, a second stop block 2082, and a sixth screw 2083. The second lock head 2081 is located above the second panel 202, and its head end is used to insert into the longitudinal side holes of the two adjacent end corner pieces 1 of the container. The second stop block 2082 is located below the second panel 202. The tail of the second lock head 2081 and the second panel 202 have corresponding through holes for the sixth screw 2083 to pass through. The lower part of the sixth screw 2083 is provided with a threaded section that is threadedly connected to the second stop block 2082, and the upper part has a second pressing part 2084 that is pressed against the upper surface of the second lock head 2081.

[0079] Reference Figure 9 , Figure 7 The support member 30 includes a first base 301, a second base 302, and a double-ended screw 303. The threaded sections at both ends of the double-ended screw 303 are threadedly connected to the first base 301 and the second base 302, respectively. Rotating the double-ended screw 303 can control the first base 301 and the second base 302 to move closer or further away from each other. When they move away from each other, they are used to press against the lateral side 11 of the adjacent corner pieces 1 of the two containers.

[0080] The container non-displacement lashing device of this embodiment includes the following steps when in use:

[0081] S1. Base installation and positioning: Install two double bases 20 (one at the front and one at the back) at the adjacent corner joints of the two containers, and then install four single bases 10 at the four corners of the outer ends of the two containers. All bases are fixed to the bearing plane by welding or bolting.

[0082] S2. Double container placement guide: hoist the two containers to the base respectively, and slowly lower them so that the bottom hole of the container corner piece 1 is aligned with the first cone 103 of the single base 10 and the second cone 203 of the double base 20. The corner piece 1 automatically slides into place along the inclined surface of the cone, completing the initial positioning of the double container.

[0083] S3. Single-unit base 10 limit (outer four corners): Repeat the single-container binding mode operation for the four single-unit bases 10 at the outer ends of the two containers to limit the longitudinal, lateral and vertical displacement of the containers respectively.

[0084] S4. Double base 20 limit switch (common middle end):

[0085] S41. Lateral limit: Rotate the fourth screw 206 and the fifth screw 207 so that the screw ends simultaneously press against the longitudinal side 12 of the container corner piece 1, locking the lateral displacement of the two containers;

[0086] S42. Vertical limit: The corner pieces 1 at the adjacent ends of the two containers are vertically locked by two second vertical locking mechanisms 208 in the same way as the first vertical locking mechanism 108, thereby limiting the vertical displacement of the two containers.

[0087] S5. Support 30 limiting (middle longitudinal): Two support 30s (one at the front and one at the back) are installed between the corner pieces 1 of the two adjacent ends of the containers. The first base 301 of the two support 30s is inserted between the corner pieces 1 of the two adjacent ends of the containers. The double-headed screw 303 is rotated so that the first base 301 moves away from each other and presses against the lateral side 11 of the corner pieces 1 of the two adjacent ends of the containers. The longitudinal relative displacement of the two containers is limited by the bidirectional pressing force, which supplements the longitudinal constraint in the middle position.

[0088] S6. Fully constrained: Under the synergistic action of the single base 10, the double base 20, and the support 30, the two containers are completely constrained in the longitudinal, lateral, and vertical directions, with no gaps or displacement space, achieving absolute fixation of the two containers without displacement.

[0089] Compared with traditional tie-down devices such as twist locks and bottom cones, this invention does not use clearance fit locking from the bottom hole of corner piece 1. Instead, it achieves displacement-free fixation through a three-dimensional fully enclosed constraint method of tightening with transverse screws, longitudinal screws, and vertical locking mechanism. This ensures that the container does not move under unstable conditions such as dynamic impact and shaking, and guarantees the operating accuracy of internal equipment. It can meet the stringent requirements of high-precision equipment mounting and dynamic operation.

[0090] This invention supports independent binding of a single box and parallel binding of two boxes, which can be flexibly adapted to different operating scenarios.

8. A method for applying the container non-displacement lashing device as described in claim 1, characterized in that, Includes the following steps: S1. Base installation and positioning: The four single bases are firmly fixed to the bearing plane by welding or bolting according to the positions of the four corner pieces at the bottom of the container, forming a stable four-point bearing reference, ensuring that the position of the single bases corresponds precisely to the corner pieces of the container. S2. Container positioning guidance: The container is hoisted to the top of the four single-unit bases and slowly lowered so that the bottom holes of the four corner pieces of the container are aligned with the first cones on the four single-unit bases. The bottom hole walls of the corner pieces automatically slide into place along the inclined surface of the first cone, completing the initial positioning of the container. S3. Longitudinal freedom limit: Rotate the first screw to make the end of the first screw press against the lateral side of the container corner fitting, that is, the longitudinal position of the container is completely locked by the screw tightening force, thus restricting the longitudinal displacement of the container. S4. Lateral freedom limit: Rotate the second screw to make the end of the second screw press against the longitudinal side of the container corner piece, that is, the lateral position of the container is completely locked by the screw tightening force, thus restricting the lateral displacement of the container. S5. Vertical freedom limit: Insert the head of the first lock into the side hole of the container corner fitting, pass the third screw through the tail of the first lock and the first panel, then connect the first stop to the threaded section of the third screw and press it against the lower surface of the first panel, then rotate the third screw, the first pressing part presses down on the first lock, so that the first lock tightly locks the side hole of the corner fitting, and the container is completely pressed vertically by the cooperation of the first lock and the first stop, thus limiting the vertical jump and displacement of the container; S6. Full constraint completed: The four corners of the container are constrained in three dimensions in the longitudinal, lateral and vertical directions through the above steps. Under the combined action of the four single-unit bases, all three degrees of freedom are restricted, achieving absolute fixation of the single container without displacement.

9. A method for applying the container non-displacement lashing device as described in claim 3, characterized in that, Includes the following steps: S1. Base installation and positioning: Install two double bases at the adjacent corner joints of the two containers, and then install four single bases at the four outer corners of the two containers. S2. Double container placement guide: Hoist the two containers to the top of the base respectively, and slowly lower them so that the bottom holes of the container corner fittings are aligned with the first cone of the single base and the second cone of the double base. The corner fittings will automatically slide into place along the inclined surface of the cone, completing the initial positioning of the double containers. S3. Single-unit base limit: Repeat the single-unit binding mode operation for the four single-unit bases at the outer ends of the two containers to limit the longitudinal, lateral and vertical displacement of the containers respectively. S4. Double base limit: S41. Lateral limit: Rotate the fourth and fifth screws to simultaneously press the screw ends against the longitudinal side of the container corner fittings, locking the lateral displacement of the two containers; S42. Vertical limit: Using the same operating method as the first vertical locking mechanism, the corner pieces at the adjacent ends of the two containers are vertically locked by two second vertical locking mechanisms to limit the vertical displacement of the two containers; S5. Support component limiting: Two support components are installed between the corner pieces of the two adjacent ends of the containers. The first base of the two support components is inserted between the corner pieces of the two adjacent ends of the containers. The double-ended screw is rotated so that the first base is moved away from each other and clamps the lateral side of the corner pieces of the two adjacent ends of the containers. The longitudinal relative displacement of the two containers is limited by the bidirectional clamping force, which supplements the longitudinal constraint in the middle position. S6. Fully constrained: Under the synergistic action of the single-unit base, double-unit base, and support components, the two containers are completely constrained in the longitudinal, lateral, and vertical directions, with no gaps or displacement space, achieving absolute fixation of the two containers without displacement.
