[0026] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the following further describes the present invention in detail in conjunction with the drawings and specific embodiments.

[0027] Refer to Figures 1 to 6An aircraft cabin floor operation protection scaffold as shown, the scaffold has a building guiding part and a bearing part, the top surface of the bearing part is the top surface of the scaffold, and a force unloading flat plate 1 capable of moving vertically relative to the top surface is arranged on the top surface of the bearing part; a buffer supporting structure is arranged on the outer side surface of the scaffold, there are a plurality of the buffer supporting structures, and they are respectively located on one outer side surface of the scaffold, and at the same time all the buffer supporting structures use the top surface of the bearing part as the center to serve as the outer edge of the bearing part; the buffer supporting structure has a free end and a hinged end, wherein the scaffold has a bottom surface, and the bottom surface corresponds to the top surface of the bearing part; the hinged end is hinged and matched with the bottom surface; the free end is detachably connected with the top surface of the bearing part through an abutting structural member; the force unloading flat plate 1 is horizontally laid on the top surface, and an elastic buffer is arranged below the force unloading flat plate 1; an opening 2 penetrating through the force unloading flat plate 1 up and down is arranged on the force unloading flat plate 1, and a locking member always located between the openings 2 is arranged on the top surface of the bearing part, and the locking member is used to limit the vertical upward movement of the force unloading flat plate 1; when a vertical force acts on the upper surface of the force unloading flat plate 1, the force unloading flat plate 1 is pressed downwards, and when the vertical force is released, the force unloading flat plate 1 moves upwards by means of the elastic buffer to force the abutting structural member to fail to realize the separation between the free end and the top surface of the bearing part, and during the separation, the hinged end forces the free end of the buffer supporting structure to turn towards the ground under the action of gravity to realize the unfolded posture.

[0028] When using the protection scaffold, maintenance personnel climb onto the scaffold through the building guiding part and move to the upper part of the force unloading flat plate 1. Before that, the locking member is in the locked state. When the maintenance personnel move onto the force unloading flat plate 1, the locking member is opened so that the locking member no longer locks the force unloading flat plate 1. At this time, the maintenance personnel can start the maintenance work. During the maintenance process, if the maintenance personnel accidentally fall from the scaffold, there will be no external force pressing on the force unloading flat plate 1, and since the locking member is in the opened state and no longer locks the force unloading flat plate 1 at this time, the force unloading flat plate 1 will be pushed upwards by the elastic buffer. When the force unloading flat plate 1 moves upwards, the abutting structural member fails and the free end of the buffer supporting mechanism is separated from the top surface of the bearing part, and it automatically unfolds under the action of gravity. The maintenance personnel who accidentally fall from the scaffold will fall onto the buffer supporting mechanism to prevent personnel from being injured.

[0029] Reference Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the locking member includes a lock block 3 and a bolt 4. The lock block 3 is fixedly connected to the top surface of the bearing part and is located in the opening 2 on the force unloading flat plate 1. The bolt 4 is slidably arranged on the top of the force unloading flat plate 1 and is located beside the opening 2, and the bolt 4 is inserted into the lock block 3.

[0030] When the scaffolding is not in use, insert the bolt 4 into the lock block 3 to lock the load-relieving flat plate 1, so that the load-relieving flat plate 1 will not move upward, thereby separating the free end of the buffer support mechanism from the top surface of the bearing part. When using the scaffolding, pull out the bolt 4 from the lock block 3, no longer lock the load-relieving flat plate 1, and then use the weight of the maintenance personnel themselves to press down and limit the load-relieving flat plate 1.

[0031] Reference Figure 2 、 Figure 3 、 Figure 4 As shown, each of the abutting structural members includes a buckle 5, the buckle 5 is hinged to the free end of the corresponding buffer support structure, and the top surface of the bearing part is provided with a limiting rod 6 corresponding to the buckle 5 for the buckle 5 to be snapped into, and the buckle 5 is detachably connected to the limiting rod 6.

[0032] When installing the scaffolding, connect the corresponding buffer support structure to the limiting rod 6 through the buckle 5, and at the same time limit the buckle 5 through the load-relieving flat plate 1, so that the buckle 5 will not detach from the limiting rod 6 under normal conditions.

[0033] Reference Figure 5 As shown, the elastic buffer member is composed of four positioning columns 7 distributed in a matrix. A return spring 8 is provided on each positioning column 7, and each return spring 8 abuts against the load-relieving flat plate 1 and is located below the load-relieving flat plate 1.

[0034] When using the scaffolding, the maintenance personnel move onto the load-relieving flat plate 1. At this time, the load-relieving flat plate 1 will be pressed downward by the weight of the maintenance personnel themselves. The return spring 8 located below the load-relieving flat plate 1 will be compressed. At the same time, the state of the load-relieving flat plate 1 when moving downward will limit the buckle 5, so that the buckle 5 will not automatically fall off the limiting rod 6. If the maintenance personnel accidentally fall from the scaffolding, the return spring 8 under the load-relieving flat plate 1 will return to its original state from the compressed state due to the absence of external force, and will push the load-relieving flat plate 1 upward. At this time, the load-relieving flat plate 1 will no longer be able to limit the buckle 5.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, each of the buffer support structures includes:

[0036] A protective plate 9, located on the outer side of the scaffolding. The lower end of the protective plate 9 is the hinged end of the above-mentioned buffer support structure, and the above-mentioned buckle 5 is hinged to the upper end of the protective plate 9. The upper end of the protective plate 9 is the free end of the above-mentioned buffer support structure;

[0037] The first spring 10, corresponding to the buckle 5 one by one, is located below the buckle 5. The first spring 10 is fixedly connected to the top of the bearing part and abuts against the buckle 5. The first spring 10 is used to lift the buckle 5 so that the buckle 5 is disengaged from the limiting rod 6;

[0038] The second spring 11, corresponding to the protection plate 9 one by one, is located on one side of the bearing part. The second spring 11 is fixedly connected to the bearing part and abuts against the protection plate 9. The second spring 11 is used to lift the upper end of the protection plate 9 away from the bearing part so that the protection plate 9 automatically unfolds.

[0039] When the protection plate 9 is in use, first hinge the lower end of the protection plate 9 to the ground of the scaffolding, and then connect the free end of the protection plate 9 to the bearing part through the buckle 5. At this time, the first spring 10 corresponding to the buckle 5 and the second spring 11 corresponding to the protection plate 9 are respectively compressed by the buckle 5 and the protection plate 9. When the maintenance personnel fall from the self-unloading flat plate 1, the self-unloading flat plate 1 is lifted upward by the return spring 8 and moves upward. The self-unloading flat plate 1 no longer limits the buckle 5, and the buckle 5 will be lifted by the first spring 10 and disengaged from the limiting rod 6. At the same time, the second spring 11 will return from the compressed state and push the free end of the protection plate 9 away from the scaffolding, and then the protection plate 9 will automatically unfold outward with the hinge as the center under the action of gravity, thereby catching the accidentally fallen maintenance personnel and ensuring the personal safety of the maintenance personnel.

[0040] Reference Figure 1 、 Figure 2 As shown in the figure, a pull rod 12 is provided at the lower end of each protection plate 9, and a tension spring 13 is provided on the pull rod 12. One end of the tension spring 13 is fixedly connected to the pull rod 12, and the other end is fixedly connected to the bottom of the scaffolding.

[0041] When the upper end of the protection plate 9 approaches the bearing part, the tension spring 13 provided on the pull rod 12 is in a stretched state. When the protection plate 9 starts to unfold, the tension spring 13 will retract from the stretched state. The retracting force of the tension spring 13 will assist the protection plate 9 to unfold, making the unfolding speed of the protection plate 9 faster and the reaction more sensitive, ensuring that the protection plate 9 can unfold smoothly within the time from when the maintenance personnel accidentally fall from the scaffolding to landing.

[0042] Reference Figure 4 As shown in the figure, the protection plate 9 is made of a flexible material with a certain elasticity.

[0043] In order to better protect the personal safety of the maintenance personnel, the protection plate 9 needs to be made of a flexible material with a certain elasticity, such as rubber, sponge, etc.

[0044] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
