Description

Technical Field

[0001] This utility model relates to the field of aviation materials and equipment technology, and in particular to a hoisting device for aircraft maintenance. Background Technology

[0002] During the maintenance of some large aircraft, it is necessary to install fuselage accessories such as tail gun turrets and ensure that the installation is stable and reliable. However, there is no suitable equipment in the aviation materials and equipment department to carry out the hoisting, and the turret weighs more than 300 kg. Currently, the hoisting is usually carried out using cloth straps: first, the turret is tied to the ground with cloth straps and connected to the crane. Then, the turret is slowly hoisted up, and the turret is aligned with the vertical plane of the fuselage. Finally, the turret is fixed to the fuselage with bolts. After checking that everything is correct, the installation is completed.

[0003] Using conveyor belts for hoisting lacks stable anchor points, making the turret prone to movement and posing safety risks. Furthermore, the connection point between the turret and the fuselage is vertical; if the turret is uneven, it cannot align properly with the vertical plane, resulting in torque during bolt connection and potential bolt deformation or damage. Even if not damaged, this increases rework and impacts installation efficiency. On the other hand, using conveyor belts for high-altitude work requires constant supervision and leveling to prevent displacement, posing safety hazards to workers and increasing labor costs, requiring 4 to 5 people to complete the installation.

[0028] Figures 1 to 3 This invention illustrates an embodiment of a hoisting device for aircraft maintenance. The hoisting device for aircraft maintenance in this embodiment includes a lifting ring 1 and three adjustable slings 2. One end of each sling 2 is connected to the lifting ring 1, and the other end of each sling 2 is provided with a connecting component 3 for connecting the object to be hoisted.

[0029] The hoisting equipment for aircraft maintenance in this embodiment, taking the hoisting of turret 4 as an example, firstly, turret 4 is placed on a support. The connecting components 3 of the three slings 2 are connected to different parts of turret 4 respectively. Then, the lifting ring 1 is connected to the crane. A leveling device is placed on turret 4, and the lengths of each sling 2 are adjusted to keep turret 4 horizontal. Finally, turret 4 is vertically hoisted upwards, close to the fuselage, and the bolt holes 41 on turret 4 are used to complete the installation and fixation of turret 4 to the fuselage. During the hoisting process, the three slings 2 can keep turret 4 stable and prevent displacement. At the same time, it can keep turret 4 horizontal, eliminating the need for personnel to supervise and adjust the horizontal position of turret 4 throughout the process, avoiding the risks of high-altitude operations, saving manpower, and also helping to prevent deformation and damage to the fixing bolts of turret 4. The structure is simple and easy to use. See details. Figure 3 The three slings 2 can keep the turret 4 stable. Of course, in other embodiments, the number of slings 2 can be further increased, but this will lead to a more complex equipment structure and higher cost. The slings 2 are made of steel cables, which have high strength and good reliability, and avoid breakage. Of course, in other embodiments, the slings 2 can also be made of other materials, as long as they can match the weight of the object being lifted.

[0030] See details Figure 2 In this embodiment, the connecting component 3 includes a connecting block 31. One end of the connecting block 31 is provided with a first receiving groove 32 and a detachable first locking member. The end of the sling 2 away from the lifting ring 1 is located in the first receiving groove 32 and connected to the first locking member. The other end of the connecting block 31 is provided with a second receiving groove 34 and a detachable second locking member. In use, the end of the sling 2 away from the lifting ring 1 is placed in the first receiving groove 32, and then the first locking member is locked to connect the sling 2 to the connecting block 31. The lifting part of the turret 4 is placed in the second receiving groove 34, and then the second locking member is locked to connect the connecting block 31 to the turret 4. The structure is simple and the operation is convenient. Preferably, the first locking member and the second locking member are bolts (only the bolt holes are shown in the figure, the bolts are not shown), which occupy little space, have reliable locking, and are easy to disassemble. Of course, in other embodiments, the first locking member and the second locking member can also be locking pins, buckles, etc.

[0031] In a preferred embodiment, the first receiving groove 32 is a U-shaped groove, and the end of the sling 2 away from the lifting ring 1 is provided with a first annular portion 21, through which the first locking member passes. This connection structure allows the sling 2 and the connecting block 31 to rotate relative to each other, facilitating adjustment to a stable stress state.

[0032] Furthermore, in this embodiment, a sling loop 22 is provided between the inner side of the first annular portion 21 and the first locking member. Providing the sling loop 22 prevents the first annular portion 21 of the sling 2 from directly contacting the first locking member, thus avoiding wire or strand breakage and further improving reliability.

[0033] In a preferred embodiment, the end of the sling 2 away from the lifting ring 1 is bent and fixed by the rope clamp 23 to form a first loop portion 21. When it is necessary to adjust the length of the sling 2, the length of the bent portion is changed first, and then the bent portion is fixed to the main body portion again by the rope clamp 23, which is convenient to operate.

[0034] Furthermore, in this embodiment, the second receiving groove 34 is a U-shaped groove and faces the opposite direction to the first receiving groove 32, which can make full use of the length of the connecting block 31, avoid the components at both ends of the connecting block 31 from affecting each other, and make the operation more convenient.

[0035] In a preferred embodiment, one end of the sling 2 is bent and fixed by the rope clamp 23 to form a second annular portion 24, which is connected to the lifting ring 1. This structure is simple and reliable. Preferably, a sling loop 22 is also provided between the inner side of the second annular portion 24 and the lifting ring 1. This can prevent the second annular portion 24 of the sling 2 from directly contacting the lifting ring 1, thus avoiding breakage of the steel cable wires and strands, and further improving reliability.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
