Description

Technical Field

[0001] The utility model relates to the technical field of aircraft maintenance, in particular to an auxiliary tool for removing aircraft cabin carpets. Background Art

[0002] Removing cabin carpet is a critical yet tedious task during aircraft maintenance and scheduled inspections. Because civil aircraft place particular emphasis on safety, economy, and comfort, cabin carpeting is used to enhance the passenger experience. However, carpeting accumulates stains and wears over time, necessitating regular cleaning or replacement. However, carpet removal is not only labor-intensive but also presents numerous technical challenges, making the entire process both time-consuming and labor-intensive. Aircraft cabin carpet removal presents the following challenges: 1. Significant Removal Workload: Aircraft cabin carpets cover a large area and are typically adhered to the floor with special double-sided tape to ensure they remain secure and prevent slippage. During the removal process, each carpet piece must be cleaned individually, requiring not only extensive physical labor but also a high degree of meticulousness and patience. 2. Low Removal Efficiency: Because carpets are so firmly adhered, traditional manual removal methods require engineers to painstakingly pull them off. This is not only inefficient, but also easily leads to damage to the carpet, increasing the workload of subsequent repairs; 3. Engineers are prone to injury: During the demolition process, engineers usually need to squat and kneel on the ground for a long time, which not only increases the risk of occupational diseases such as lumbar muscle strain and knee arthritis, but also easily leads to sprains or strains due to improper operation.

[0026] The following is combined with Figure 1 To the attached Figure 4 The utility model is further described.

[0027] An auxiliary tool for removing aircraft cabin carpets comprises: a chassis 1, with universal wheels 2 respectively installed at the four corners of its lower end; a lower clamping plate 25, arranged at the upper end of the chassis 1, and arranged in the horizontal direction; an upper clamping plate 26, located directly above the lower clamping plate 25, and fixedly connected to the lower clamping plate 25 via a connecting mechanism to clamp the head end of the carpet 30; a synchronous transmission mechanism, driving the lower clamping plate 25 and the upper clamping plate 26 to rotate synchronously in the same direction; a plug-in mechanism I, one end of which is transmission-connected to the synchronous transmission mechanism, and the lower clamping plate 25 is movably plug-connected to the other end of the plug-in mechanism I; and a plug-in mechanism II, one end of which is transmission-connected to the synchronous transmission mechanism, and the upper clamping plate 26 is movably plug-connected to the other end of the plug-in mechanism II. During use, the entire auxiliary tool chassis 1 is rolled onto the universal wheels 2 to the area where the carpet is to be removed. A section of the cabin carpet is manually removed and placed between the lower clamping plate 25 and the upper clamping plate 26. The upper clamping plate 2 is then fastened to the lower clamping plate 25 via the connecting mechanism to secure the carpet. The synchronous transmission mechanism operates by driving the lower clamping plate 25 to rotate via the plug-in mechanism I, and the upper clamping plate 26 to rotate synchronously and in the same direction via the plug-in mechanism II. This separates the carpet from the cabin floor and winds it around the upper clamping plate 26 and lower clamping plate 25 for reeling. After reeling, the carpet can be detached from the plug-in mechanisms I and II, facilitating removal and cleaning. This improves the efficiency of aircraft cabin carpet removal, reduces the workload for engineers, and effectively avoids safety hazards during the removal process.

[0028] In one embodiment of the present invention, the connection mechanism may be configured as follows: screw holes II 37 are provided at the left and right ends of the lower clamping plate 25, and through holes 38 are provided at the left and right ends of the upper clamping plate 26. Bolts 29 pass through the through holes 38 and are screwed into the screw holes II 37. Tightening the bolts 29 clamps the lower clamping plate 25 and the upper clamping plate 26, while loosening the bolts 29 separates the upper clamping plate 26 from the lower clamping plate 25, making operation convenient.

[0029] In one embodiment of the present invention, an armrest 3 is further included which is mounted on the upper front end of the chassis 1. The armrest 3 can be used to conveniently drive the entire auxiliary tooling to move, thereby improving the convenience of operation.

[0031] In one embodiment of the present invention, a disc-shaped baffle plate I 27 is longitudinally disposed on the left side of the lower plate 25, and a disc-shaped baffle plate II 28 is longitudinally disposed on the right side of the upper plate 26. The provision of baffle plates I 27 and II 28 allows the carpet to be regularly wound around the lower and upper plates 25, 26, preventing the carpet from straying.

[0032] In one embodiment of the present utility model, the synchronous transmission mechanism includes a dual-output motor 6 mounted on the chassis 1, a right-angle commutator I 13 mounted on the left end of the chassis 1, a right-angle commutator II 14 mounted on the right end of the chassis 1, a right-angle commutator III 19 mounted on the chassis 1 and located directly above the right-angle commutator I 13, and a right-angle commutator IV 20 mounted on the chassis 1 and located directly above the right-angle commutator II 14. The right end of the transmission shaft I 7 is connected to one output shaft of the dual-output motor 6 through a coupling I 11, and its left end is connected to one end of the right-angle commutator I 13 through a coupling III 15.

The dual-output motor 6 rotates, and simultaneously drives the transmission shaft I 7 and the transmission shaft II 8 to rotate. When the transmission shaft I 7 rotates, it drives the transmission shaft III 9 to rotate after being reversed by the right-angle commutator I 13. When the transmission shaft II8 rotates, it drives the transmission shaft IV 10 to rotate after being reversed by the right-angle commutator II 14. The transmission shaft III 9 rotates, passes through the right-angle commutator III 19, and then drives the lower clamping plate 25 to rotate by the plug-in mechanism I. The transmission shaft IV 10 rotates, passes through the right-angle commutator IV 20, and then drives the upper clamping plate 26 to rotate synchronously in the same direction by the plug-in mechanism II.

[0033] In one embodiment of the present invention, the plug-in mechanism I includes a connector I 23, the left end of which is drivingly connected to the right-angle commutator III 19. A shaft head I 32 with a rectangular longitudinal cross-section is coaxially disposed on the left end of the lower clamping plate 25. A socket I that matches the shaft head I 32 is horizontally disposed on the right end of the connector I 23. The lower clamping plate 25 is inserted into the socket I of the connector I 23 via the shaft head I 32. Because the rectangular shaft head I 32 is inserted into the socket I of the connector I 23, rotation of the connector I 23 drives the lower clamping plate 25 to rotate.

[0034] In one embodiment of the present invention, the plug-in mechanism II includes a connector II 24, the right side of which is drivingly connected to the right-angle commutator IV 20. A shaft head II 33 with a rectangular longitudinal cross-section is coaxially disposed on the right side of the upper clamping plate 26. A socket II that matches the shaft head II 33 is horizontally disposed on the left side of the connector II 24. The upper clamping plate 26 is inserted into the socket II of the connector II 24 via the shaft head II 33. Because the rectangular shaft head II 33 is inserted into the socket II of the connector II 24, rotation of the connector II 24 drives the upper clamping plate 26 to rotate.

[0035] In one embodiment of the present invention, it also includes a connecting shaft 31, the outer diameter of the connecting shaft 31 matches the inner diameter of the socket I, the left end of the connecting shaft 31 is inserted into the socket I, and the right end of the connecting shaft 31 is provided with a socket III 40 that matches the shaft head I 32.

When the carpet is wound and needs to be removed, the lower clamping plate 25 and the upper clamping plate 26 fixed together are moved horizontally to the left. At this time, the screw 39 slides in the slide groove 34 to provide guidance, and the spring 35 is compressed until the shaft head II 33 is completely removed from the connector II 24. Thereafter, the lower clamping plate 25 and the upper clamping plate 26 fixed together are tilted upward and moved to the right to disengage the shaft head I 32 from the socket III 40 of the connecting shaft 31, and the wound carpet is removed. After the carpet is removed as a whole, the shaft head I 32 of the lower clamping plate 25 and the upper clamping plate 26 fixed together are inserted into the socket III 40 of the connecting shaft 31 and the compression spring 35 is moved to the left. Then, the lower clamping plate 25 and the upper clamping plate 26 fixed together are rotated downward to a horizontal state, so that the shaft head II 33 is aligned with the socket II of the connector II 24. After that, the whole is moved horizontally to the right so that the shaft head II 33 is inserted into the socket II of the connector II 24. The installation is completed.
