Description

Technical Field

[0001] The utility model relates to the technical field of helicopters, in particular to a wooden supporting platform for a side door. Background Art

[0002] The helicopter side door is an important part of the helicopter fuselage and an indispensable component. During storage, special attention should be paid to force balance and safety to prevent stress deformation and falling. In order to facilitate the protection of the side door during maintenance, assembly, turnover and production, a wooden support platform is required.

[0003] After searching, the Chinese patent with the announcement number CN216332706U discloses a light helicopter fuselage. There is no special storage design for the side door of this helicopter. When the on-site staff stores it, there is a risk of storage disorder and damage to the side door.

[0004] The above-mentioned helicopter side door still has some shortcomings when in use. When the aircraft is repaired or assembled, there is usually a lack of a wooden support platform for storing the side door, which makes it inconvenient to repair or assemble the aircraft. If the stability of the supporting surface of the wooden support platform is low, the door may shift and become unbalanced during the storage process. It is not convenient to flexibly adjust the height of the platform's footing according to the terrain conditions when the platform is used. As a result, the platform may shake due to the instability of the supporting surface, which reduces the safety of the platform. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] As attached Figure 1-4 As shown, the utility model provides an embodiment: a side hatch wooden support platform, including two chassis main beams 1, both ends of the two chassis main beams 1 are fixedly connected to the chassis main beam 2, the top of the chassis main beam 1 is fixedly connected to two columns 3, the interior of the two chassis main beams 1 is fixedly installed with two reinforcing connecting beams 4, the outer side of the chassis main beam 1 is fixedly connected to two ground support threaded sleeves 7, the internal threads of the ground support threaded sleeves 7 are connected to the ground support screw rod 8, one end of the ground support screw rod 8 is fixedly connected to the ground support universal chassis 9, the other end of the ground support screw rod 8 is fixedly connected to the ground support hand wheel 10, the bottom of the chassis main beam 1 is fixedly installed with two universal casters with brakes 11, the chassis main beam 1 and the chassis main beam 2 are The steel is welded, and the combination of the chassis main beam 1 and the chassis main beam 2 2 and the reinforced connecting beam 4 is conducive to forming a relatively stable bottom platform, and the ground support screw rod 8 rotates inside the ground support threaded sleeve 7, which is convenient for driving the ground support universal chassis 9 at one end of the ground support screw rod 8 to move, so as to adjust the position according to needs. The universal caster 11 with brakes is convenient for moving the platform. Four adjustable ground supports are used under the bracket, and two ground support threaded sleeves 7 and ground support screw rods 8 and ground support handwheels 10 are provided on the left and right. The ground support screw rod 8 is adjusted by the internal thread to facilitate rapid height adjustment, so that the bracket can always remain level during storage, while improving the overall stability, which is conducive to avoiding displacement or falling during the storage of the hatch.

[0029] As attached Figure 2As shown, the other ends of the two columns 3 on both sides are fixedly connected with wooden support channel steels 5, and the interior of the wooden support channel steels 5 is fixedly connected with wooden supports 12 that match the hatch. The bottom of the wooden support channel steels 5 and the tops of the chassis main beam 1 and the chassis main beam 2 2 are fixedly connected with two triangular stiffening plates 6. The wooden supports 12 that match the hatch are fixedly connected to the wooden support channel steels 5 by bolts. The two wooden supports 12 that match the hatch are symmetrically distributed. The two wooden supports 12 that match the hatch facilitate the placement of the hatch, and the triangular stiffening plates 6 facilitate strengthening the stability of the platform structure.

[0030] As attached Figure 1 As shown, the number of columns 3 is set to four, the number of ground support threaded sleeves 7 is set to four, the two base frame main beams 1 are symmetrically distributed, the columns 3 play a supporting role, and the number of ground support threaded sleeves 7 is set to four to facilitate the adjustment of the ground support screw rods 8 on both sides of the platform.

[0031] As attached Figure 4 As shown, a cotton pad 13 is provided on the top of the wooden support 12 that matches the cabin door, and a canvas 14 is provided on the outside of the wooden support 12 that matches the cabin door. A special cotton pad 13 is used to cover the wooden support surface of the wooden support 12 that matches the cabin door, and the cotton pad 13 and the outer side of the wooden support are covered with canvas 14, which is pressed tightly with a pressure strip. The wooden support surface changes according to the change of the cabin door shape. After laying the cotton pad 13 and the canvas 14, it is convenient to fit closely with the aircraft cabin door, which is conducive to the stable placement of the cabin door without warping, and at the same time it is convenient to reduce the deformation of the cabin door surface caused by uneven stress during placement.

[0032] Working principle: When using the wooden support platform, push the wooden support platform through the universal brake caster 11 and move it to the position of the side hatch door to be used. According to the terrain conditions at the side hatch door, turn the ground support handwheel 10 that needs to be adjusted, so that the ground support handwheel 10 drives the ground support screw rod 8 to rotate inside the ground support threaded sleeve 7, so that it is convenient to adjust the height of the corresponding ground support screw rod 8 under the action of the ground support threaded sleeve 7, so that it is convenient for the ground support screw rod 8 to drive the chassis main beam 1 to rise, so that the chassis main beam 1 drives the chassis main beam 2 2 to rise, and support is provided under the action of the ground support universal chassis 9, which is conducive to reducing the displacement phenomenon caused by the loose fixation of the universal brake caster 11, improving the stability of the platform, and facilitating the storage and use of the hatch door.
