Description

Technical Field

[0001] This invention relates to an on-site adjustment device, specifically an on-site adjustment device for palletized cargo. Background Technology

[0002] In ground handling operations for air logistics, there is a critical "last mile" between when goods are palletized in the warehouse and when they are loaded onto the aircraft. This process mainly involves transporting palletized goods to the apron by trailer. However, there is a significant operational pain point in the transportation and handover process: according to on-site operational statistics, approximately 20% of the goods tilt during trailer transport, with an average of 1,200 such abnormal pallets needing to be handled annually.

[0003] For tilted palletized cargo, the current routine handling mainly relies on two intervention methods: for slightly tilted cargo, on-site workers usually manually push and straighten it; for severely tilted cargo, it is necessary to temporarily call in heavy forklifts in the yard and use the forklifts' forks to push the bottom edge of the pallet to forcibly adjust it.

[0004] In long-term practical operation, the above two conventional methods of manual intervention have revealed many insurmountable defects, specifically in the following aspects: First, the operational efficiency is extremely low. Whether it's organizing manual pushing or waiting for forklifts on the vast tarmac, the entire tilting adjustment process is time-consuming. Especially during peak periods with heavy flight takeoffs and landings, this inefficient approach can easily cause delays and directly impact flight punctuality.

[0005] Secondly, there are significant safety hazards. On the one hand, on-site operators directly intervene in pushing and lifting heavy goods, posing an extremely high risk to personal safety; on the other hand, when the forklift performs a rough and forceful pushing operation, the force is concentrated at the point of impact, which can easily cause irreversible physical damage to the ULD (Unified Container Floor) itself.

[0006] Third, it significantly increases overall operating costs. The frequent occurrence of cargo tilting necessitates frequent manpower deployment for on-site sorting, which also occupies normal forklift resources, indirectly increasing the labor and equipment maintenance costs for logistics companies.

[0007] Fourth, it can easily lead to serious cargo safety risks. The tilting of cargo itself, as well as the forceful pushing by forklifts, often causes the cargo inside the pallet to be squeezed and collapse, especially for soft-packaged goods with poor pressure resistance, which can easily cause cargo damage and lead to high economic claims.

[0008] In addition, airport aprons are special outdoor working environments where power is often unavailable, which limits the introduction of conventional electric auxiliary equipment.

[0009] In summary, existing methods for tilting palletized cargo are severely incompatible with the overall intelligent and efficient development strategies of modern logistics companies. Therefore, there is an urgent need in this field to innovate through technological means and develop a dedicated palletized cargo adjustment device that can operate safely in power-free environments on the tarmac, effectively solving the aforementioned technical challenges. Summary of the Invention

[0010] To address the aforementioned shortcomings in existing technologies, the present invention aims to provide a palletized cargo on-site adjustment device. This invention seeks to solve the problems of low efficiency, significant safety hazards, easy cargo damage, and indirectly increased operating costs associated with existing manual sorting and forklift pushing methods. More importantly, this invention aims to overcome the environmental limitations of airport tarmacs where power is unavailable, providing a purely physical mechanical righting device that requires no external power input, generates substantial thrust with single-person operation, and seamlessly integrates with existing trailers.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: A palletized cargo on-site adjustment device, comprising: A mobile chassis is used to support the entire device and enable movement and fixation. The mobile chassis includes frames on both sides, and a hollow structure for accommodating container plates is formed between the frames on both sides. Mechanical force-multiplying mechanisms are respectively installed on the frame on the corresponding side; The bidirectional adjustable jacking arm system is connected to the mechanical force amplification mechanism on the corresponding side; The bidirectional adjustable jacking arm systems on both sides are configured to extend into the hollow structure to perform jacking operations on the container plates respectively.

[0012] Furthermore, horizontal beams are respectively provided on the frame on both sides, and the mechanical force amplification mechanism is respectively installed at the center of the horizontal beam on the corresponding side.

[0013] Furthermore, the mobile chassis adopts a rigid frame and is equipped with heavy-duty swivel wheels with brakes at the bottom.

[0014] Furthermore, the rigid frame includes a front frame and a rear frame that are separated front and rear, with the hollow structure formed between the front frame and the rear frame, so that the rigid frame can accommodate the container plate from both sides.

[0015] Furthermore, at least two heavy-duty casters with brakes are independently installed at the bottom of both the front frame and the rear frame; the mechanical force amplification mechanism and the bidirectional adjustable jacking arm system are symmetrically installed on the front frame and the rear frame, respectively.

[0016] Furthermore, the mechanical force amplification mechanism is a helical gear transmission mechanism, which is independently set on both sides of the device. Each side of the helical gear transmission mechanism includes a large helical gear and a small helical gear that mesh with each other.

[0017] Furthermore, each side of the mechanical force-amplifying mechanism also includes an extended ratchet wrench lever. The operator drives the gear by moving the ratchet wrench lever up and down, converting the rotational motion of the gear into a linear thrust of the single-sided push arm, thereby achieving independent retraction and straightening operations.

[0018] Furthermore, the device integrates a mechanical self-locking or ratchet mechanism, which allows the gear mechanism to apply force intermittently and lock automatically, preventing the cargo from tipping back and causing danger.

[0019] Furthermore, the end of the bidirectional adjustable push arm system is provided with a contoured pad for close contact with the side frames of the container plate.

[0020] Furthermore, the bidirectional adjustable push arm system is pre-tightened using a simple ratchet or screw mechanism to eliminate gaps. This invention has the following beneficial effects: 1. Purely physical force amplification, perfectly adapted to the power-free environment of the tarmac: This device does not contain any components requiring external power, such as electric, pneumatic, or hydraulic pumps. Based on a clever helical gear transmission mechanical structure, it amplifies the operating force of a single person, achieving a maximum pushing weight of several tons under the core constraint of no power source on the outdoor tarmac site. This completely eliminates dependence on energy supply and is extremely beneficial for subsequent equipment maintenance.

[0021] 2. Significantly Increased Operational Efficiency: The structure of this device facilitates rapid movement and positioning. Simultaneous operation of the pre-tightening mechanisms on both sides allows for clamping of pallets in a very short time. Compared to waiting for forklift dispatch or manual pushing, this significantly reduces the time required for single cargo adjustment, substantially lowering the average processing time and effectively ensuring on-time performance of flights.

[0022] 3. Achieving separation of man and machine, ensuring the safety of personnel and goods: This invention replaces manual pushing with mechanical force enhancement, minimizing the operator's labor intensity and effectively avoiding the safety risks associated with direct human intervention. Simultaneously, the contoured pads of the push arm prevent physical damage to the ULD (Understanding Floor Plane) body caused by forcibly pushing with forklift forks, and the internal mechanical self-locking structure ensures stability during the pushing process, preventing heavy goods from tipping back and comprehensively reducing the risk of damage claims.

[0023] 4. Effective control of overall operating costs: This device is mainly operated by a single person, which significantly reduces the frequent use and scheduling pressure of high-cost heavy forklift resources on site. Under reasonable manufacturing costs, it brings a direct return on investment to logistics companies by reducing reliance on manpower and equipment wear and tear. Attached Figure Description

[0038] Example

[0039] I. Specific structural layout of the device

[0040] like Figures 1 to 3 As shown, the device mainly consists of a mobile chassis 7, a dual-sided independent mechanical force-increasing mechanism 5, and a bidirectional adjustable jacking arm system 6.

[0041] A mobile chassis 7 with an openable hollow structure: The mobile chassis 7 employs a rigid frame and is equipped with heavy-duty swivel wheels 4 with brakes at the bottom, facilitating easy movement to the work site by one person. To handle tilted goods without obstruction, the rigid frame does not have a crossbar physical obstruction in the middle; instead, it forms a large hollow structure 3 to accommodate pallets. The net width of this internal hollow structure 3 is configured to exceed the maximum width of a standard pallet and a carrying trailer. Horizontal beams 8 are installed inside the frames of the front frame 1 and the rear frame 2, serving as mounting references for the respective side mechanisms and not crossing the hollow structure 3.

[0042] Dual-sided independent jacking and force-enhancing system: On the aforementioned front frame 1 and rear frame 2, there are symmetrically distributed sets of horizontally telescopic, bi-directional adjustable jacking arm systems 6. Each jacking arm is equipped with a contour pad and can be pre-tightened via a simple ratchet or screw handle. In terms of power transmission, the mechanical force-enhancing mechanism 5 is independently installed at the center of the corresponding horizontal beam 8 on the front frame 1 and rear frame 2. Each side is individually equipped with a meshing helical gear set and an extended ratchet wrench lever 51.

[0043] In terms of power transmission, this device abandons the central synchronous transmission and independently sets the mechanical force amplification mechanism 5 on the front and rear sides of the device. Each side's force amplification mechanism adopts a helical gear transmission scheme, including a meshing large helical gear and a small helical gear. At the power input end, each side is equipped with an extended ratchet wrench lever 51. At the same time, to ensure operational safety, the device integrates a mechanical self-locking or ratchet mechanism.

[0044] II. Working Process and Operating Procedures of the Device

[0045] Based on the aforementioned chassis design, which allows for splitting in the middle and independent movement on both sides, the specific operational procedures for handling cargo with complex and asymmetrical tilt on the apron are as follows: Step 1: Separation, Integration, and Assembly. In the initial stage of operation, the operator first separates the adjustment device into two independent parts: a front frame 1 and a rear frame 2. Then, the separated front and rear parts are moved to the front and rear ends of the trailer carrying the tilted pallet, integrating the pallet and trailer together into the hollow structure 3 inside. Next, the front and rear parts are pushed towards the center and assembled, reforming the device into a rigid frame that encloses the cargo. After assembly, the position is fine-tuned so that the centers of the two push arms are aligned with the center of gravity of the pallet, and the brakes on all casters 4 are engaged to secure the chassis.

[0046] Step Two: Independent Pre-tensioning. Due to the varying sizes of the tilt gaps on both sides of the cargo, the operator needs to manually adjust the bidirectional adjustable push arm system 6 on both sides independently. At this time, the extension of the push arms is completely independent, and the operator can flexibly adjust it according to the actual gap until the contour pads on both sides are tightly fitted to the side frames of the container plate to eliminate the gap.

[0047] Step 3: Independent Push-Up. After pre-tightening, the operator uses the corresponding ratchet wrench levers 51 on both sides to drive the mechanical force amplification mechanisms 5 on both sides to apply a pushing force in the opposite direction of the tilt. This pushing-up method allows the operator to apply a larger pushing force on one side according to the eccentricity of the cargo, achieving asymmetrical straightening.

[0048] Step 4: Safety Locking. During the pushing process and after adjustment, the independent mechanical self-locking or ratchet mechanisms on both sides allow intermittent force application and automatic locking, resolutely preventing the cargo from tipping back and ensuring the safety of personnel and goods.

[0049] Combination Figure 4 As shown, this embodiment demonstrates a practical working scenario where the pallet cargo adjustment device is used in conjunction with the trailer 9. When the pallet cargo on the trailer 9 tilts and needs adjustment, the operator first separates the front frame 1 and rear frame 2 of the mobile chassis 7 in the middle. Then, the front frame 1 and rear frame 2 are pushed to both ends of the trailer 9, so that the trailer 9 and the pallet it carries are completely incorporated into the hollow structure formed by the merging of the front frame 1 and rear frame 2. After the merging is completed, the operator depresses the brakes on the bottom casters 4 to firmly support the entire device. Next, the operator adjusts the bidirectional adjustable push arm system 6 located on both sides, causing the contoured pads at their ends to extend inward and tightly fit against the side edges of the pallet, completing the pre-tightening step to eliminate gaps. Finally, the operator moves the ratchet wrench lever 51 mounted on the horizontal beam 8 up and down to drive the mechanical force-adding mechanism to apply a huge linear thrust in the opposite direction of the cargo tilt, thereby safely and efficiently completing the asymmetrical straightening operation of the container pallet.

[0050] The embodiments described above are merely further illustrations of the present invention and are not intended to limit the present invention in any other way. The present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding modifications and changes based on the present invention, but all such modifications and changes should fall within the protection scope of the present invention.
