A cabinet shipping vehicle

Abstract

This invention relates to the field of cabinet transportation technology, specifically a cabinet transport vehicle. An elliptical block, which can be inserted into and rotated into an elliptical hole, is provided on an internally threaded rod. A T-shaped rod extending to the outside of the elliptical block and pressed against a piston assembly is elastically installed in an open rod. A locking nut that compresses the T-shaped rod is provided on the externally threaded rod. The beneficial effect is that by providing a fixing assembly with a locking nut for further limiting, after the elliptical block rotates and shifts, the threaded rotation of the locking nut not only restricts the rotation of the threaded rod but also uses its compression to drive the T-shaped rod to compress the tee pipe, driving the top rod to compress the elliptical block. This ensures the elliptical block fits tightly against the inner wall of the locking cavity of the cabinet, thereby fixing the elliptical block, avoiding gaps, and greatly improving the stability of the fixed connection.

Description

Technical Field

[0001] This invention relates to the field of cabinet transportation technology, specifically a cabinet transport vehicle. Background Art

[0002] Large cabinet products are inconvenient to ship, and there are no special standard shipping tools, which causes many inconveniences in actual work.

[0003] Existing containers are usually transported using devices such as trolleys, so the containers need to be installed on the trolleys. Common installation methods are often found on shipping containers, which usually involve setting up elliptical mounting holes and interlocking elliptical blocks. By utilizing the rotation and misalignment of the elliptical blocks, a fixed connection is formed.

[0004] However, several problems exist in the actual installation and connection process. The cabinet is usually flush with the ground, while the traction trolley is often equipped with rollers, making it difficult to adapt the installation height. Additional hoisting and adaptation of containers and other cabinets is required, which is cumbersome and inefficient. Furthermore, the single elliptical mounting hole and the locking fit of the elliptical block will leave a rotation gap. Therefore, the fasteners are not fixed and are very easy to fall off due to vibration, deflection and other reasons during installation and transportation, resulting in insufficient connection stability. Summary of the Invention

This makes the elliptical block fit tightly against the inner wall of the locking cavity of the cabinet, thereby fixing the elliptical block, avoiding gaps, and greatly improving the stability of the fixed connection.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 11 The present invention provides a technical solution:

[0036] A cabinet transport vehicle includes a transport vehicle composed of multiple interconnected movable support assemblies 2. One end of the transport vehicle connected to the multiple movable support assemblies 2 is connected to a traction device via a pull rod 8. Each movable support assembly 2 includes a fixed column 12 fixedly connected to a cabinet body 1. An upper rotating arm 14 and a lower rotating arm 15, parallel to each other, are rotatably mounted on the fixed column 12. The other ends of the upper rotating arm 14 and the lower rotating arm 15 are rotatably connected to a support column 16. A roller 6 is provided at the lower end of the support column 16. Adjacent movable support assemblies 2... The upper and lower crossbeams 10 and 11 are fixedly connected to each other. The lower end of the fixed column 12 is fixed to the cabinet 1 by the fixed component 7, and the upper end of the fixed column 12 is fixed to the cabinet 1 by the strap 5. The lower end of the side wall opposite to the adjacent fixed column 12 is provided with a support corner seat 22. The lower crossbeam 11 is fixedly installed on a pair of support corner seats 22 by bolts. The adjacent top blocks 3 are fixedly connected to each other by the upper crossbeam 10. The side wall of the top block 3 is provided with a strap buckle 13, and the end of the strap 5 is fixedly tied to the strap buckle 13.

[0037] The mobile support assembly 2 is moved easily by using the rollers 6, and a rigid and stable connection is achieved between adjacent mobile support assemblies 2 by the upper crossbeam 10 and the lower crossbeam 11. The lower end of the mobile support assembly 2 is fixedly connected to the cabinet 1 by the fixing assembly 7, and the upper end of the mobile support assembly 2 is fixedly connected to the cabinet 1 by the straps 5, thereby stably installing the transport vehicle on the cabinet 1.

[0038] A jack 4 is provided on the fixed column 12 to pull the lower rotating arm 15 to rotate. A top block 3 is provided at the upper end of the fixed column 12. The upper end of the jack 4 is rotatably mounted on the top block 3. A limit groove 24 is provided on the upper rotating arm 14. The telescopic end of the jack 4 passes through the limit groove 24 and is fixedly connected to the lower rotating arm 15.

[0039] During installation, the retraction of jack 4 first drives the upper rotating arm 14 and the lower rotating arm 15 to rotate upward. At this time, the support column 16 moves upward, making the roller 6 flush with the lower end of the cabinet 1. Then, the movable support assembly 2 is installed on the cabinet 1 by pushing. After installation and fixing, the extension of jack 4 drives the upper rotating arm 14 and the lower rotating arm 15 to rotate downward, pulling the support column 16 downward for support. With the support of the roller 6, the cabinet is driven to be suspended in the air, supported by the roller 6, which facilitates subsequent traction, movement and transportation.

[0040] A connecting seat 17 is provided on the supporting column 16. A detachable push rod 20 is rotatably mounted on the connecting seat 17. A rotating seat 23 is provided in the middle section of the lower crossbeam 11. A connecting rod 9 is connected to the rotating seat 23. The other end of the connecting rod 9 is connected to a pull rod 8. A traction device is externally connected to the pull rod 8. A pair of mounting seats 19 are provided at the lower end of the connection position between the connecting rod 9 and the pull rod 8. A swing arm 18 is rotatably mounted on the upper end of the connecting seat 17 through a bearing 21. The other end of the swing arm 18 is connected to the mounting seat 19.

[0041] By setting up a rotatable swing arm 18, a connecting rod 9, and a tie rod 8, it is adapted to the steering and transportation of the traction device, and the push rod 20 is used to realize the movement and installation of the individual moving support assembly 2.

[0042] The fixing component 7 includes a threaded rod assembly inserted into the fixing post 12 and an elliptical mounting hole 35 provided on the cabinet 1. The cabinet 1 has a locking cavity 36 with an inner diameter larger than the major diameter of the elliptical mounting hole 35 located inside the mounting elliptical hole 35. A three-way pipe 54 is provided in the locking cavity 36. The middle port of the three-way pipe 54 is directly opposite the mounting elliptical hole 35, and a piston assembly is elastically installed in the middle port. The other two ports of the three-way pipe 54 are inserted with top rods 55 that are offset from the mounting elliptical hole 35. The threaded rod assembly includes an internal threaded rod 38, an external threaded rod 26, and an open rod 43. An elliptical block 37 is provided on the internal threaded rod 38, which can be inserted into the mounting elliptical hole 35 and rotated offset. A T-shaped rod 44 extending to the outside of the elliptical block 37 and pressed against the piston assembly is elastically installed in the open rod 43. A locking nut 27 that compresses the T-shaped rod 44 is provided on the external threaded rod 26.

[0043] The movable support assembly 2 is positioned and installed by inserting the elliptical block 37 into the mounting elliptical hole 35. The rotation of the threaded rod assembly drives the rotation of the elliptical block 37, thereby creating a misalignment with the mounting elliptical hole 35 and achieving the purpose of limiting the connection. At this time, the threaded rotation of the locking nut 27 limits the rotation of the threaded rod assembly. During its rotation and screwing, the T-shaped rod 44 is squeezed. The T-shaped rod 44 is pressed against the piston assembly of the three-way pipe 54, thereby driving the push rod 55 to extend in the opposite direction, thereby squeezing the elastically installed elliptical block 37. This makes the elliptical block 37 fit tightly against the inner wall of the locking cavity 36, avoiding connection gaps, thereby achieving the purpose of stable and fixed connection and preventing loosening of the connection caused by vibration and deflection.

[0044] Working principle: First, the retraction of jack 4 drives the support column 16 to move upward, making the roller 6 flush with the lower end of the cabinet 1. Then, the movable support component 2 is installed on the cabinet 1 by pushing. The movable support component 2 is positioned and installed by inserting the elliptical block 37 into the mounting elliptical hole 35. The rotation of the threaded rod component drives the rotation of the elliptical block 37, thereby creating a misalignment with the mounting elliptical hole 35 and achieving the purpose of limiting the connection. At this time, the threaded rotation of the locking nut 27 presses against the bushing 28, thereby limiting the rotation of the threaded rod component and driving the top rod 55 to extend in the opposite direction, thereby compressing the elastically installed elliptical block 37. This makes the elliptical block 37 fit tightly against the inner wall of the locking cavity 36, avoiding connection gaps, thereby achieving the purpose of stable and fixed connection and preventing loosening of the connection caused by vibration and deflection.

[0045] The upper crossbeam 10 and lower crossbeam 11 achieve a rigid and stable connection between adjacent mobile support components 2. The lower end of the mobile support component 2 is fixedly connected to the cabinet 1 using the fixing component 7. The upper end of the mobile support component 2 is fixedly connected to the cabinet 1 using the straps 5. This allows the transport vehicle to be stably installed on the cabinet 1. After installation and fixing, the extension of the jack 4 is used to pull the support column 16 downward for support. With the support of the rollers 6, the cabinet is driven to suspend in the air. The rollers 6 provide support, which facilitates subsequent traction, movement and transportation.

[0046] Example 2: Based on Example 1, in order to facilitate the transportation and movement of the mobile support component 2, the transport vehicle also includes a storage rack 30. The lower end of the storage rack 30 is provided with a mounting base beam 32, and the lower end of the mounting base beam 32 is provided with a forklift base 31. Multiple storage elliptical holes 34 with the same size as the mounting elliptical holes 35 are provided on both sides of the mounting base beam 32. The mobile support component 2 can be installed in the storage elliptical holes 34 by inserting the fixing component 7. The upper end of the storage rack 30 is provided with a lifting ring for hoisting and an ear seat for bolting to the top block 3 in the mobile support component 2. The storage rack 30 is provided with a hanging bracket for storing the push rod 20.

[0047] By setting up the storage rack 30, it is easy to store and attach the mobile support component 2 of a single module. The forklift base 31 facilitates the overall transportation of the storage rack 30, thereby increasing its applicability.

[0048] Example 3: Based on Example 1, a bushing 28 is provided at the lower end of the fixed column 12. A threaded hole 39 is provided at one end of the bushing 28 near the fixed column 12, and a stepped inner hole 40 is provided at the other end of the bushing 28. One end of the stepped inner hole 40 connects to the threaded hole 39, and the inner diameter of the stepped inner hole 40 is larger than the inner diameter of the threaded hole 39. An internally threaded rod 38 is threadedly rotatably installed in the threaded hole 39. A through slot is provided in the open rod 43, and the through slot is directly opposite the stepped inner hole 40. One end of the externally threaded rod 26 is located in the stepped inner hole 40, and the other end of the externally threaded rod 26... One end extends to the outside of the bushing 28, and the outer end of the external threaded rod 26 is inserted through a rotating locking rod 29. A T-shaped rod 44 is inserted into the open rod 43. The crossbar of the T-shaped rod 44 extends along the through slot of the open rod 43 into the stepped inner hole 40. The longitudinal bar of the T-shaped rod 44 slides through the internal threaded rod 38 and the elliptical block 37. A first spring 45 is provided in the stepped inner hole 40. The first spring 45 is sleeved on the open rod 43, and one end of the first spring 45 abuts against the stepped surface of the stepped inner hole 40, while the other end of the first spring 45 abuts against the crossbar of the T-shaped rod 44.

[0049] The T-shaped rod 44 is elastically installed by setting the first spring 45, and the extension and retraction range of the T-shaped rod 44 is limited by the stepped inner hole 40. Then, the piston assembly is squeezed by driving the T-shaped rod 44.

[0050] A locking nut 27 is rotatably mounted on the threaded rod 26. The outer diameter of the locking nut 27 is larger than the inner diameter of the stepped inner hole 40. The other end of the locking nut 27 is provided with a compression collar 41, which is inserted into the annular gap between the stepped inner hole 40 and the threaded rod 26. The outer diameter of the compression collar 41 is equal to the inner diameter of the stepped inner hole 40. The end of the compression collar 41 is rotatably pressed onto the crossbar of the T-shaped rod 44. The inner diameter of the middle section of the compression collar 41 is smaller than the inner diameter of the stepped inner hole 40. A bearing ring 42 is sleeved on the arc outer wall of the middle section of the compression collar 41. A locking bolt 25 is rotatably mounted on the arc outer wall of the bushing 28. The end of the locking bolt 25 is pressed onto the bearing ring 42.

[0051] By setting the compression collar 41 and the locking nut 27 to cooperate, the locking nut 27 drives the compression collar 41 to press against the crossbar of the T-shaped rod 44 during the thread rotation, so that the first spring 45 is compressed, the end of the T-shaped rod 44 is pressed against the piston assembly, and the locking nut 27 is pressed against the end face of the bushing 28, restricting the further rotation of the threaded rod assembly. The locking bolt 25 further limits the position of the compression collar 41.

[0052] The end of the internally threaded rod 38 is provided with a telescopic inner cavity 51. One end of the telescopic inner cavity 51 is provided with a retaining ring 52. The elliptical block 37 is located outside the telescopic inner cavity 51. The inner wall of the telescopic inner cavity 51 is provided with a side groove. The other side of the elliptical block 37 is provided with a connecting pipe that passes through the retaining ring 52 and extends into the telescopic inner cavity 51. The end of the connecting pipe is provided with a linkage block 50 that is slidably inserted into the side groove. A second spring 47 is pressed between the linkage block 50 and the inner wall of the telescopic inner cavity 51.

[0053] By setting the linkage block 50 and the second spring 47, the elliptical block 37 can be elastically extended and retracted at the end of the internal thread rod 38, so that the internal thread rod 38 can drive the elliptical block 37 to rotate synchronously, and the elliptical block 37 can slide along the telescopic inner cavity 51. Under the reverse compression of the top rod 55, the elliptical block 37 is driven to slide in the opposite direction. At this time, the second spring 47 is compressed, and the elliptical block 37 is pressed against the inner wall of the locking inner cavity 36.

[0054] The piston assembly includes a piston rod 49 and a telescopic block 46. The telescopic block 46 is slidably installed in the middle port of the three-way pipe 54. One end of the telescopic block 46 extends to the outside of the middle port, and the other end of the telescopic block 46 is connected to the piston rod 49. The inner cavity of the middle port of the three-way pipe 54 is set in a stepped shape. A third spring 48 is pressed between the telescopic block 46 and the stepped surface of the middle port. A pair of limiting blocks 33 facing the top rod 55 are provided on the inner wall of the locking inner cavity 36. The elliptical block 37 is provided with a limiting hole 53 that cooperates with the limiting block 33.

[0055] The telescopic block 46 is elastically installed by setting a third spring 48. Then, under the compression of the T-shaped rod 44, the telescopic block 46 and the piston rod 49 slide into the three-way pipe 54. The pressure inside the three-way pipe 54 increases, which drives the top rods 55 on both sides to extend and press against the end face of the elliptical block 37. This causes the elliptical block 37 to press against the inner wall of the locking cavity 36, thereby allowing the limiting hole 53 to engage with the limiting block 33, forming a further limiting and fixing, preventing the elliptical block 37 from deflecting, and greatly improving the stability of the connection.

[0056] During disassembly, first remove the locking bolt 25 to stop the compression ring 41. Then, rotate the locking nut 27 in the opposite direction to reset the T-shaped rod 44 and the piston assembly, thereby releasing the compression between the push rod 55 and the elliptical block 37. The elliptical block 37 is reset under the action of the second spring 47. Then, rotate the threaded rod assembly in the opposite direction to align the elliptical block 37 with the mounting elliptical hole 35, thereby pulling out the movable support assembly 2 to achieve the purpose of disassembly.
