Description

Technical Field

[0001] This utility model belongs to the field of aviation technology, and in particular relates to an engine storage and transport box with lifting function. Background Technology

[0002] The engine is the primary moving component of a helicopter. Engine power is transmitted through the transmission system to the rotor system, hydraulic system, lubrication system, and power generation system, ultimately providing the helicopter with lift for the main rotor, counter-torque for the tail rotor, electricity from the generator, power for the hydraulic pumps, and power for the lubrication pumps. Due to its large size, weight, and complex structure, the engine is generally only disassembled in a few cases, such as when it is returned to the factory for repairs, scheduled maintenance, or when disassembling its connected transmission system components. Disassembly requires lifting, moving, and lowering using large equipment such as cranes, hoists, gantry cranes, or spider cranes. Therefore, engine disassembly work generally needs to be carried out in a repair shop.

[0003] Currently, missions require helicopters to be used in covert, field environments for extended periods. This leads to a shortage of tools, equipment, and spare parts for helicopter maintenance. In particular, large tools and equipment are essential. If a helicopter engine malfunctions or requires scheduled maintenance and replacement, the lack of large tools and equipment, or their inability to reach the site quickly, could ground the helicopter and impact mission completion. Utility Model Content

[0004] This utility model provides an engine storage and transport box with lifting function, proposing a deformable box design. Using a box as the basic structure, the device can be unfolded into a lifting structure through the nesting, extension, rotation, and fastening of various components of the box structure. This enables the lifting of heavy objects such as engines to high places. By modifying the basic box structure, a simple box acquires the function of a crane, not only improving the box's functionality and economic efficiency but also reducing the amount of protective equipment, and providing a degree of deception and concealment—truly achieving multiple benefits. The technical solution is as follows:

[0005] In a first aspect, an engine storage and transport box with lifting function is provided, comprising: a front wall panel 1, a rectangular slide rail 2, a front wall panel telescopic plate 4, a hanging pulley 5, a sling 6, a bottom plate telescopic plate 9, a bottom plate 10, a lifting device 11, a side wall panel 12, a rear wall panel 13, a rear wall panel telescopic plate 14, an upper wall panel 15, a stay cable 17, an upper wall panel telescopic plate 18, and a connecting pulley 19.

[0032] The features and illustrative embodiments of various aspects of this utility model will now be described in detail. In the following detailed description, numerous specific details are set forth in order to provide a comprehensive understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. This utility model is by no means limited to any specific arrangements and methods set forth below, but covers any improvements, substitutions, and modifications to the structure, method, and apparatus without departing from the spirit of this utility model. In the accompanying drawings and the following description, well-known structures and techniques are not shown to avoid unnecessarily obscuring this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other, and the various embodiments can be referenced and cited from each other.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] This utility model provides an engine storage and transport box with lifting function, mainly composed of: front wall panel 1, rectangular slide rail 2, T-bolt 3, front wall panel telescopic plate 4, hanging pulley 5, sling 6, upper wall panel fixing pin 7, fixing pin 8, bottom plate telescopic plate 9, bottom plate 10, lifting device 11, side wall panel 12, rear wall panel 13, rear wall panel telescopic plate 14, upper wall panel 15, upper wall panel telescopic plate fixing pin 16, inclined cable 17, upper wall panel telescopic plate 18, and adapter pulley 19.

[0036] This device is a deformable rectangular box structure. Through the nesting, extension, rotation, and fastening of the various components of the box structure, the device has the function of lifting heavy objects such as engines to high places.

[0037] Side wall panels 12 form the two sides of the box, bottom plate 10 forms the bottom surface of the box, upper wall panel 15 forms the top surface of the box, front wall panel 1 forms the front of the box, and rear wall panel 13 forms the rear of the box.

[0038] The base plate telescopic plate 9 can be pulled outward or retracted inward from the internal cavity of the base plate 10 to maintain the balance of the front side of the device. The front wall plate telescopic plate 4 can be pulled outward or retracted inward from the internal cavity of the front wall plate 1. The rear wall plate telescopic plate 14 can be pulled outward or retracted inward from the internal cavity of the rear wall plate 13. The upper wall plate telescopic plate 18 can be pulled outward or retracted inward from the internal cavity of the upper wall plate 15.

[0039] The rear ends of the left and right sidewall panels 12 are vertically hinged to the left and right sides of the rear wall panel 13 via hinges. The left and right sidewall panels 12 can be extended 180° backward around the vertical hinges to maintain the balance of the rear side of the device. The rear end of the upper wall panel 15 is horizontally hinged to the upper end of the rear wall panel telescopic plate 14 via a hinge. The upper wall panel 15 can be extended 90° backward around the horizontal hinge. The front wall panel 1 is perpendicular to and fixed to the upper wall panel telescopic plate 18. The rear wall panel 13 is perpendicular to and fixed to the bottom plate 10.

[0040] After the left and right side panels 12 are extended 180° backward around the vertical hinge, they are connected to the rear upper corner and the rear end of the front panel 1 by a diagonal cable 17. This is to enhance the stability of the device after deformation. When the device deforms, the base plate telescopic plate 9 also needs to be fully pulled out of the base plate 10 to enhance the stability of the device after deformation. The upper panel 15 can be extended 90° backward around the horizontal hinge, and the upper panel 15 is flush with the rear panel telescopic plate 14. The upper panel fixing pin 7 is used to fix the flushness of the upper panel 15 and the rear panel telescopic plate 14.

[0041] When the rear wall panel telescopic plate 14 is pulled outward from the internal cavity of the rear wall panel 13 to its limit position, the limit position of the rear wall panel telescopic plate 14 and the rear wall panel 13 is fixed by the fixing pin 8. When the upper wall panel telescopic plate 18 is pulled outward from the internal cavity of the upper wall panel 15 to its limit position, the limit position of the upper wall panel telescopic plate 18 and the upper wall panel 15 is fixed by the upper wall panel telescopic plate fixing pin 16.

[0042] A rectangular slide rail 2 is installed at the upper end of the internal cavity of the front wall panel 1. A T-bolt 3 is screwed into the front wall panel telescopic plate 4 from the upper end of the rectangular slide rail 2. After the front wall panel telescopic plate 4 is pulled outward or retracted inward from the internal cavity of the front wall panel 1 to the desired position, the T-bolt 3 is tightened to press the front wall panel 1, so that the front wall panel telescopic plate 4 can be fixedly limited to the desired position.

[0043] A hanging pulley 5 is installed at the middle of the inner side of the front telescopic plate 4, and a transition pulley 19 is installed at the middle of the inner side of the front wall plate 1. A lifting device 11 is installed at the corner where the bottom plate 10 and the rear wall plate 13 meet. The lifting device 11 can be manual or automatic. The sling 6 is sent from the lifting device 11, passes through the transition pulley 19 and the hanging pulley 5 respectively, and is finally tied to the engine mounting structure.

[0044] The first stage of device deployment: The left and right side panels 12 extend 180° backward around the rear panel 13 via vertical hinges to maintain the balance of the rear side of the device. The base plate telescopic plate 9 is pulled outward from the internal cavity of the base plate 10 to maintain the balance of the front side of the device.

[0045] The second stage of device deployment: The upper wall panel 15 unfolds 90° backward around the upper horizontal hinge of the wall panel telescopic plate 14. The front wall panel telescopic plate 4 is pulled outward from the internal cavity of the front wall panel 1. The T-bolt 3 is screwed into the front wall panel telescopic plate 4 from the upper end of the rectangular slide rail 2. After the front wall panel telescopic plate 4 is pulled outward from the internal cavity of the front wall panel 1 to the desired position, the T-bolt 3 is tightened to press the front wall panel 1, so that the front wall panel telescopic plate 4 can be fixed and limited in the desired position. The sling 6 is issued from the lifting device 11, passes through the adapter pulley 19 and the hanging pulley 5 respectively, and is finally tied to the engine mounting structure.

[0046] The third stage of device deployment: The upper wall panel telescopic plate 18 is pulled outward from the internal cavity of the upper wall panel 15. After the upper wall panel telescopic plate 18 is pulled outward from the internal cavity of the upper wall panel 15 to the limit position, the upper wall panel telescopic plate 18 and the upper wall panel 15 are fixed at the limit position by the upper wall panel telescopic plate fixing pin 16.

[0047] The fourth stage of device deployment: The rear wall panel telescopic plate 14 is pulled outward from the internal cavity of the rear wall panel 13. When the rear wall panel telescopic plate 14 is pulled outward from the internal cavity of the rear wall panel 13 to its limit position, the limit position of the rear wall panel telescopic plate 14 and the rear wall panel 13 is fixed by the fixing pin 8. At this point, the device is fully deployed.

[0048] After the device is fully deployed, the upper rear corners of the left and right side wall panels 12 and the rear end of the front wall panel 1 are connected by cable 17 to enhance the stability of the device after deformation.

[0049] The lifting device 11 begins operation, lifting heavy objects such as the engine. After the engine or other heavy objects are lifted to a suitable height, the T-bolts 3 can be loosened. Then, the wall panel telescopic plate 4 can be adjusted to be pulled outward or retracted inward from the internal cavity of the front wall panel 1 to the desired position. Finally, the T-bolts 3 are tightened to press the front wall panel 1, so that the front wall panel telescopic plate 4 can be fixedly limited to different positions as needed.

[0050] The folding procedure of the device is the exact opposite of the unfolding procedure, and will not be described in detail here.

[0051] The key features of this utility model are as follows:

[0052] (1) The base plate telescopic plate 9 can be pulled outward or retracted inward from the internal cavity of the base plate 10. The front wall plate telescopic plate 4 can be pulled outward or retracted inward from the internal cavity of the front wall plate 1. The rear wall plate telescopic plate 14 can be pulled outward or retracted inward from the internal cavity of the rear wall plate 13.
