[0002] Aircraft maintenance tooling platforms are specialized equipment designed specifically for aircraft maintenance and repair, providing a safe and stable operating space for personnel. They typically possess lifting, moving, or fixing functions, allowing for flexible adjustment of height and position according to the maintenance area (such as fuselage, wings, engines, etc.). Equipped with safety guardrails, non-slip surfaces, tool storage devices, and other safety and auxiliary facilities, they can support personnel, tools, and parts, ensuring the standardization and safety of maintenance operations while improving efficiency. Their design must comply with aviation maintenance safety standards and ergonomic requirements.

[0003] During aircraft maintenance, when employees are pressed for time and need to speed up the work, they may fail to lock their safety latches to avoid frequent unlocking that could affect efficiency, or due to a lack of prior accidents. In such cases, the platform may suddenly move or tilt due to shaking, misoperation, or mechanical failure, causing employees to fall from a height, resulting in serious injury or death, posing a significant safety hazard.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 5 An aircraft maintenance tooling platform includes: a base plate 1, a column 2 fixedly installed on the base plate 1, a lifting platform 3 slidably connected to the side wall of the column 2, a motor 4 fixedly connected to the top of the base plate 1, a lead screw 5 fixedly connected to the output end of the motor 4, a slider 6 slidably connected to the side wall of the lead screw 5, and the slider 6 fixedly connected to one side of the lifting platform 3.

[0027] The slider 6 is provided with a threaded locking assembly 7, which is used to control the threaded connection between the slider 6 and the lead screw 5. The threaded locking assembly 7 includes a mounting groove 71 opened in the slider 6, and a first threaded locking block 72 and a second threaded locking block 73 are slidably connected in the mounting groove 71.

[0028] A drive assembly 8 is provided on one side of the threaded locking assembly 7, and a key assembly 9 is provided on one side of the drive assembly 8. Two sets of threaded locking assemblies 7, drive assemblies 8, and key assemblies 9 are arranged symmetrically.

[0029] The symmetrical design requires operators to insert both key components 9 into the key slots 86 to control the lifting platform 3. This repetitive operation forces maintenance personnel to ensure their own safety before carrying out maintenance work, thus further guaranteeing their safety.

[0030] The first threaded locking block 72 is connected to the mounting groove 71 via the first spring 77, and the second threaded locking block 73 is connected to the mounting groove 71 via the second spring 78.

[0031] The design of spring 77 and spring 78 allows the first threaded locking block 72 and the second threaded locking block 73 to disengage from the screw 5 when maintenance is completed and the lifting platform 3 descends to the bottom, so as to facilitate the next locking restriction.

[0032] The No. 1 threaded locking block 72 and the No. 2 threaded locking block 73 are connected by the No. 1 rack 74, the No. 2 rack 75 and the gear 76. The No. 1 rack 74, the No. 2 rack 75 and the gear 76 are set in the mounting groove 71, and the gear 76 meshes with the No. 1 rack 74 and the No. 2 rack 75.

[0033] Rack 74, rack 75, and gear 76 are configured to control the synchronous connection of threaded locking block 72 and threaded locking block 73 with lead screw 5.

[0034] The drive assembly 8 includes a horizontal groove 81 formed in the slider 6 and a vertical groove 82 formed in the lifting platform 3. A wedge rod 83 is slidably connected in the horizontal groove 81. One side of the wedge rod 83 abuts against a drive rod 84. The drive rod 84 and the vertical groove 82 are connected by a No. 3 spring 85. A key slot 86 is formed in the lifting platform 3. A key assembly 9 is installed in the key slot 86. The No. 3 spring 85 is used to control the reset of the drive rod 84.

[0035] The key assembly 9 includes a key block 91 inserted into a key slot 86. Locking slots 92 are provided on both sides of the key block 91. A locking slide rod 93 is slidably connected in the locking slot 92 by a locking spring 94. The other end of the locking slide rod 93 is inserted into a fixing slot 99, which is located in the lifting platform 3.

[0036] The top of the locking slide bar 93 is provided with an unlocking wedge groove 95. The inclined surface of the unlocking wedge groove 95 abuts against the unlocking press block 96. The unlocking press block 96 is slidably connected in the unlocking groove 97. The unlocking groove 97 is opened in the key block 91. The unlocking groove 97 and the unlocking press block 96 are connected by an unlocking connecting spring 98.

[0037] Specifically: This solution uses a linkage design between the key assembly and the threaded locking assembly to force employees to insert the key block that is bound to the safety buckle in order to unlock the platform lifting function. This ensures that employees must fasten the safety buckle properly, preventing falls from heights due to unlocked buckles and significantly improving the safety of maintenance operations.

[0038] The working principle of this utility model is as follows: When maintenance personnel enter the lifting platform 3, they need to insert the key block 91, which is bound to their own safety belt, into the key slot 86. When the key block 91 is inserted into the key slot 86, the locking slide rod 93, which is slidably connected inside the key block 91, is inserted into the fixing slot 99 under the action of the locking spring 94. Through this insertion, the key block 91 can be fixed inside the lifting platform 3, thereby ensuring the fixed connection between the employee and the lifting platform 3 and ensuring the safety of the employee.

[0039] Simultaneously, as key block 91 is inserted, it abuts against drive rod 84, causing drive rod 84 to slide downwards and press the bottom wedge rod 83, causing wedge rod 83 to move towards screw rod 5. At this time, the second threaded locking block 73, which is fixedly connected to the other end of wedge rod 83, moves synchronously towards screw rod 5. At this time, the second threaded locking block 73 and the first threaded locking block 72 are connected by a gear and rack, so that while the second threaded locking block 73 moves towards screw rod 5, the first threaded locking block 72 moves synchronously towards screw rod 5. At this time, the first threaded locking block 72 and the second threaded locking block 73 are precisely connected to screw rod 5. When motor 4 is restarted, it can drive slider 6 to slide.

[0040] If the key block 91 is not inserted, the first threaded locking block 72 and the second threaded locking block 73 cannot be tightly connected to the lead screw 5. When the motor 4 starts, it will only control the lead screw 5 to rotate. Since there is no tight threaded connection between the slider 6 and the lead screw 5, the lead screw 5 will spin freely. This design effectively restricts employees to control the lifting platform 3 to move up and down only when they lock their own key block 91, thus effectively ensuring the safety of the employees.

[0041] When unlocking is required, press the unlocking press block 96 to drive the bottom of the unlocking press block 96 to abut against the unlocking wedge groove 95 above the locking slide bar 93, causing the locking slide bar 93 to retract into the locking groove 92. At this time, the key block 91 can be pulled out. After being pulled out of the key block 91, under the reset action of the third spring 85, the first spring 77 and the second spring 78, the drive rod 84 resets upward, and the first threaded lock block 72 and the second threaded lock block 73 disengage from the lead screw 5.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
