Description

Technical Field

[0001] This utility model relates to the field of airport equipment technology, specifically to a structure for an aircraft landing pad cover. Background Technology

[0002] During airport apron construction, openings need to be made to install tethering mechanisms for hooking and securing aircraft. After the aircraft leaves, the openings need to be covered with covers. Chinese patent document application number 201120044282.7 discloses a tethering bolt for an apron, comprising: a panel, a cover plate, a chain, a groove, a crossbar, and hooks. The panel has side plates around its perimeter, and the center of the panel is hollow. A groove, which is an inverted trapezoid, is formed on the hollow structure of the panel. The opening of the groove is larger than the bottom. A crossbar passes horizontally through the opening, and hooks are provided at both ends of the crossbar. One end of the chain is installed on an inner wall of the groove, and the other end is placed on the cover plate. The cover plate has a small hole and covers the opening of the groove. The cover plate of the parking apron is hung on the crossbar by a chain. The chain can only prevent the cover plate from leaving the maximum range of the chain tension, but it cannot prevent the cover plate from being opened. On the one hand, the cover plate may be opened by wind force, causing a safety accident. On the other hand, when an aircraft passes over the cover plate, the cover plate is easy to shake, has poor stability, and is easy to damage the opening. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an airport apron gate cover structure that can improve the wind resistance and stability of the cover plate.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An airport apron mounting hole cover structure includes an installation hole on the apron, a cover plate covering the opening of the installation hole, and a mounting component inside the installation hole. The cover plate has a groove on its inner side, and the mounting component is engaged in the groove. The mounting component has a locking hole, and a locking insert is slidably mounted on the cover plate. A rotating component extends vertically through the cover plate, and a transmission assembly is provided between the rotating component and the locking insert. The rotating component is used to transmit rotational motion to the locking insert through the transmission assembly to make linear motion, so that the locking insert is inserted into or pulled out of the locking hole. The top of the rotating component is flush with or lower than the outer side of the cover plate and has a screwing part.

[0005] As a further improvement to the above technical solution: The transmission assembly includes a meshing gear and a rack, the gear being fixed to a rotating component and the rack being mounted on a locking plate.

[0006] The rotating component is a rotating shaft, and the cover plate has a vertical through hole. The rotating shaft passes through the through hole and rotates with the inner wall of the through hole.

[0007] The rotating shaft and the inner wall of the through hole are rotatably fitted by bearings.

[0008] The end of the lock insert away from the lock hole is provided with a sliding seat, which is slidably mounted on the cover plate, and the rack is mounted on the sliding seat.

[0009] The locking insert is parallel to the cover plate, and the rotating component and the slot are both perpendicular to the cover plate.

[0010] The inner side of the cover plate is provided with two spaced-apart limiting blocks, which are perpendicular to the cover plate. The slot is formed between the two limiting blocks, and the limiting blocks are provided with through holes for the lock to pass through.

[0011] The inner side of the cover plate is provided with a chain, which is attached to the tethering component by a hook.

[0012] The mechanism is an inverted U-shaped anchor rod, the bottom end of which is anchored to the inner wall of the mounting hole, and the locking hole is formed at the top of the inverted U-shaped anchor rod.

[0013] The cover plate has at least one screw hole on its outer side.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model relates to an airport apron cover structure. After the cover plate is installed at the opening of the installation hole, the rotating component is turned to insert the locking plug into the locking hole under the transmission action of the transmission component. Under the limiting action of the locking plug and the locking hole, the cover plate is kept stably installed at the opening of the installation hole. On the one hand, it improves the wind resistance of the cover plate and avoids the cover plate being blown open by the wind, thus preventing safety accidents. On the other hand, it improves stability, so that the cover plate is not easy to shake when the aircraft passes over it, and is not easy to damage the opening. Attached Figure Description

[0022] Figure 1 and Figure 2 This invention illustrates an embodiment of the airport apron aircraft tethering cover structure. The structure includes an installation hole 1 on the apron, a cover plate 2 covering the opening of the installation hole 1, and a tethering component 3 within the installation hole 1. The cover plate 2 has an inner groove 21 into which the tethering component 3 is engaged. The tethering component 3 has a locking hole 31. A locking insert 4 slides onto the cover plate 2. A rotating component 5 extends vertically through the cover plate 2. A transmission assembly 6 connects the rotating component 5 and the locking insert 4. The rotating component 5 transmits rotational motion to the locking insert 4 via the transmission assembly 6, causing the locking insert 4 to insert into or remove from the locking hole 31. The top of the rotating component 5 is flush with or lower than the outer surface of the cover plate 2 and has a screwing portion 51.

[0023] The airport apron has an aircraft access cover structure. Cover plate 2 is installed at the opening of installation hole 1. Tightening the rotating component 5, under the transmission action of the transmission component 6, causes the locking bolt 4 to be inserted into the locking hole 31 (e.g., ...). Figure 2 As shown), under the limiting action of the locking plug 4 and the locking hole 31, the cover plate 2 is kept stably covering the opening of the installation hole 1. On the one hand, it improves the wind resistance of the cover plate 2 and avoids the cover plate 2 being blown open by the wind, which would cause a safety accident. On the other hand, it improves the stability. When the aircraft passes over the cover plate 2, the cover plate 2 is not easy to shake and is not easy to damage the opening.

[0024] Furthermore, in this embodiment, the transmission assembly 6 includes a meshing gear 61 and a rack 62. The gear 61 is fixed on the rotating component 5, and the rack 62 is disposed on the locking insert 4. The rotation of the rotating component 5 drives the gear 61 to rotate, and the gear 61 drives the locking insert 4 to slide through the rack 62 to insert into or pull out of the locking hole 31.

[0025] Furthermore, in this embodiment, the rotating component 5 is a rotating shaft, and a through hole 22 is vertically penetrating the cover plate 2. The rotating shaft passes through the through hole 22 and rotates in cooperation with the inner wall of the through hole 22. Specifically, the rotating shaft and the inner wall of the through hole 22 are rotated in cooperation via a bearing 7.

[0026] Furthermore, in this embodiment, a sliding seat 41 is provided at the end of the lock 4 away from the lock hole 31. The sliding seat 41 is slidably mounted on the cover plate 2, and the rack 62 is mounted on the sliding seat 41. Specifically, the sliding seat 41 and the cover plate 2 are slidably engaged by guide grooves and guide rails (the cross-sections of the guide grooves and guide rails can be adapted to be T-shaped or dovetail-shaped). The rack 62 is fixed on the sliding seat 41 and extends along the sliding direction of the sliding seat 41.

[0027] Furthermore, in this embodiment, the locking insert 4 is parallel to the cover plate 2, and the rotating component 5 and the slot 21 are both perpendicular to the cover plate 2. The locking insert 4, being parallel to the cover plate 2, provides a force to restrict the cover plate 2 from being pulled open after it is inserted into the locking hole 31 on the mechanism 3. The slot 21 is perpendicular to the cover plate 2, so when the cover plate 2 is vertically placed over the mounting hole 1, as long as the slot 21 is aligned with the mechanism 3 below (to facilitate engagement, the chamfer at the bottom of the slot 21 can be formed into a V-shape with a larger outer edge and a smaller inner edge), the mechanism 3 can be engaged in the slot 21. That is, when the cover plate 2 is closed, the mechanism 3 is engaged in the slot 21.

[0028] Furthermore, in this embodiment, the inner side of the cover plate 2 is provided with two spaced-apart limiting blocks 23, which are perpendicular to the cover plate 2. A slot 21 is formed between the two limiting blocks 23, and the limiting blocks 23 are provided with through holes 231 for the locking insert 4 to pass through. Specifically, the locking insert 4 is perpendicular to the limiting block 23 and coaxial with the through hole 231. The through hole 231 on the limiting block 23 near the rotating component 5 passes through the limiting block 23, and the through hole 231 on the other limiting block 23 can be set as a blind hole.

[0029] Furthermore, in this embodiment, a chain 8 is provided on the inner side of the cover plate 2, and the chain 8 is hung on the tethering component 3 via a hook 9. The pulling action of the chain 8 prevents the cover plate 2 from moving away from the mounting hole 1 after it is opened.

[0030] Furthermore, in this embodiment, component 3 is an inverted U-shaped anchor rod, with its bottom end anchored to the inner wall of the mounting hole 1, and a locking hole 31 formed at the top of the inverted U-shaped anchor rod. Specifically, the inverted U-shaped anchor rod is a vertical inverted U-shape, and the locking insert 4 is perpendicular to the vertical plane of the inverted U-shaped anchor rod. After the locking insert 4 is inserted into the locking hole 31, the top arm of the inverted U-shaped anchor rod is limited above the locking insert 4 to prevent the cover plate 2 from opening upwards, thus keeping the cover plate 2 stably covering the opening of the mounting hole 1. Of course, a sleeve can also be provided at the top of the inverted U-shaped anchor rod, allowing the locking hole 31 to be formed in the sleeve.

[0031] Furthermore, in this embodiment, at least one screw hole 24 is provided on the outer side of the cover plate 2. This facilitates the opening and closing of the cover plate 2 by connecting the external cover opening component to the screw hole 24.

[0032] After opening cover 2, the aircraft can be hooked onto tether 3 via a rope hook. After cover 2 is placed over the opening, screw holes 24 can be sealed with a plug to prevent impurities from entering. The plug is then opened when the cover is opened. Other exposed holes can also be sealed in the same way.

[0033] 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.
