Description

Technical Field

[0001] This invention relates to the field of aircraft fixing devices, and more particularly to a wind-resistant fixing system for take-off and landing pads. Background Technology

[0002] Currently, commonly used landing pad wind-resistant fixing systems include concrete landing pad structures and mooring rings. During the landing pad pouring process, the mooring rings are pre-embedded in the landing pad to form a fixed structure integrated with the ground. Once the mooring rings are installed, their position is fixed and cannot be adjusted according to the parking requirements of different aircraft models, resulting in poor adaptability. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a wind-resistant fixing system for take-off and landing pads with good adaptability.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a landing pad wind-resistant fixing system, including a landing pad and at least one mooring ring. The landing pad includes a concrete base, a fixed steel plate base, a track steel plate base and a concrete counter-pressure fixing base. The cross-sectional dimension of the track steel plate base is smaller than that of the fixed steel plate base. The fixed steel plate base is set on the concrete base. The track steel plate base is set in the middle of the fixed steel plate base. The concrete counter-pressure fixing base is set on the fixed steel plate base and is set on the outside of the track steel plate base. The track structure is provided on the track steel plate base. The track structure includes at least one circular track groove and at least one radial straight track groove. Multiple circular track grooves are arranged at the same center and are spaced apart from the inside to the outside. The radial straight track groove passes through the center of the circular track groove and connects all the circular track grooves together. Multiple radial straight track grooves are arranged to cross each other. Both the annular track groove and the radial straight track groove have an inverted T-shaped structure. The annular track groove includes a first card slot and a first connecting rod slot that are connected. The cross-sectional dimension of the first connecting rod slot is smaller than that of the first card slot. The first connecting rod slot is located in the center of the first card slot and is located above the first connecting rod slot. The radial straight track groove includes a second card slot and a second connecting rod slot that are connected. The cross-sectional dimension of the second connecting rod slot is smaller than that of the second card slot. The second connecting rod slot is located in the center of the second card slot and is located above the second connecting rod slot. The machine ring includes a movable card seat, a fixed ring, and a connecting rod. The connecting rod is vertically set in the center of the movable card seat, and the fixed ring is set on the connecting rod. The tethering ring is movably installed in the track structure and can move along the track structure to any position on the track structure. The movable card seat is installed in the first card seat groove or the second card seat groove, and the connecting rod is installed in the first connecting rod groove or the second connecting rod groove. The fixed ring is installed above the circular track groove and the radial straight track groove. The first connecting rod groove and the second connecting rod groove limit the movable card seat.

[0005] Furthermore, the cross-sectional shape of both the fixed steel plate base and the track steel plate base is circular.

[0006] Furthermore, the track structure includes 10-15 circular track grooves, with a diameter difference of 1m between adjacent circular track grooves.

[0007] Furthermore, the length of the radial straight track groove is equal to the diameter of the outermost annular track groove.

[0008] Furthermore, the track structure includes 4-8 radial straight track grooves, all of which are evenly distributed around the circumference of the annular track groove.

[0009] Furthermore, the fixing ring and the connecting rod are integrated into one structure.

[0010] Furthermore, the connecting rod is vertically mounted on the movable bracket via a thread.

[0011] Furthermore, each end of one of the circular track grooves is equipped with a tethering ring that is inserted into the groove.

[0012] Furthermore, the movable card holder is shaped like a cuboid or a cylinder.

[0013] Furthermore, the connection and fit between the movable card slot and the first card slot and the second card slot are both clearance fits; The connection between the connecting rod and the first connecting rod groove and the second connecting rod groove is a clearance fit.

[0014] The beneficial effects of this invention are as follows: By setting a track structure on the track steel plate base of the landing pad, the mooring rings are movably installed in the track structure and can move to any position along the track structure. This allows the mooring rings to meet the needs of different aircraft models for different fixing points. Furthermore, they can be flexibly combined and replaced according to the size, weight, and other parameters of the aircraft model, achieving fixing for multiple aircraft models and significantly improving the adaptability of the landing pad wind-resistant fixing system. In addition, the landing pad of this invention includes a concrete base, a fixed steel plate base, a track steel plate base, and a concrete counter-pressure fixing base. The fixed steel plate base and the track steel plate base are first processed in the factory and then installed on-site, facilitating the construction of the landing pad. The concrete counter-pressure fixing base reinforces the track steel plate base with counter-pressure, improving the overall strength of the landing pad and effectively enhancing its stability and durability, thus facilitating large-scale use.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the landing pad wind-resistant fixing system of the present invention includes a landing pad and at least one mooring ring 5. The landing pad includes a concrete base 1, a fixed steel plate base 2, a track steel plate base 3, and a concrete counter-pressure fixing base 4. The cross-sectional dimension of the track steel plate base 3 is smaller than that of the fixed steel plate base 2. The fixed steel plate base 2 is set on the concrete base 1. The track steel plate base 3 is set in the middle of the fixed steel plate base 2. The concrete counter-pressure fixing base 4 is set on the fixed steel plate base 2 and is set on the outside of the track steel plate base 3. The track steel plate base 3 is provided with a track structure, which includes at least one circular track groove 31 and at least one radial straight track groove 32. The multiple circular track grooves 31 are concentric and arranged alternately from the inside to the outside. The radial straight track groove 32 passes through the center of the circular track grooves 31 and connects all the circular track grooves 31 together. The multiple radial straight track grooves 32 are arranged to cross each other. Both the annular track groove 31 and the radial straight track groove 32 are inverted T-shaped structures. The annular track groove 31 includes a first card slot groove 311 and a first connecting rod groove 312 that are connected to each other. The cross-sectional dimension of the first connecting rod groove 312 is smaller than that of the first card slot groove 311. The first connecting rod groove 312 is located in the middle of the first card slot groove 311 and is located above the first connecting rod groove 312. The radial straight track groove 32 includes a second card slot groove 321 and a second connecting rod groove 322 that are connected to each other. The cross-sectional dimension of the second connecting rod groove 322 is smaller than that of the second card slot groove 321. The second connecting rod groove 322 is located in the middle of the second card slot groove 321 and is located above the second connecting rod groove 322. The machine ring 5 includes a movable card seat 51, a fixed ring 52 and a connecting rod 53. The connecting rod 53 is vertically arranged in the center of the movable card seat 51, and the fixed ring 52 is arranged on the connecting rod 53. The tethering ring 5 is movably installed in the track structure and can move along the track structure to any position. The movable card seat 51 is installed in the first card seat groove 311 or the second card seat groove 321. The connecting rod 53 is installed in the first connecting rod groove 312 or the second connecting rod groove 322. The fixed ring 52 is installed above the ring track groove 31 and the radial straight track groove 32. The first connecting rod groove 312 and the second connecting rod groove 322 limit the movable card seat 51.

[0018] The fixed steel plate base 2 mainly serves a connecting and fixing function. The cross-sectional dimension of the track steel plate base 3 is smaller than that of the fixed steel plate base 2, meaning that the length of the track steel plate base 3's cross-section is larger than the length of the fixed steel plate base 2's cross-section, and the width of the track steel plate base 3's cross-section is larger than the width of the fixed steel plate base 2's cross-section. For example... Figure 1As shown, to improve the performance of the fixed steel plate base 2, it is horizontally positioned on the concrete base 1, and the concrete counter-pressure fixing base 4 is horizontally positioned on the fixed steel plate base 2. The fixed steel plate base 2 and the track steel plate base 3 have the same cross-sectional shape, which can be rectangular, square, circular, etc. When both the fixed steel plate base 2 and the track steel plate base 3 are circular, the diameter of the circular cross-section of the fixed steel plate base 2 is larger than the diameter of the circular cross-section of the track steel plate base 3. The track steel plate base 3 is positioned in the exact center of the fixed steel plate base 2, and the outer side of the track steel plate base 3 is where the concrete counter-pressure fixing base 4 is located. This arrangement ensures that both the fixed steel plate base 2 and the track steel plate base 2 are equipped with the concrete counter-pressure fixing base 4, effectively improving the performance of the concrete counter-pressure fixing base 4.

[0019] The track structure provides an installation position for the tethering ring 5, allowing it to move to any position along the track structure, thus meeting the different fixing point requirements of different aircraft models. The track structure of this invention consists of a circular track groove 31 and a radial straight track groove 32, enabling the tethering ring 5 to move to most positions on the track steel plate base 3, thus meeting the different fixing point requirements of different aircraft models. For example... Figure 1 As shown, in order to improve the performance of the track structure, the preferred parameters of the track structure are as follows: the track structure includes 10-15 circular track grooves 31, the diameter difference between adjacent circular track grooves 31 is 1m, and also includes 4-8 radial straight track grooves 32, all of which are evenly distributed around the circumference of the circular track grooves 31; and the length of the radial straight track grooves 32 is equal to the diameter of the outermost circular track groove 31.

[0020] The limiting effect of the first connecting rod groove 312 and the second connecting rod groove 322 on the movable bracket 51 means that the size of the first connecting rod groove 312 and the second connecting rod groove 322 is smaller than the size of the movable bracket 51, so the movable bracket 51 cannot move into the first connecting rod groove 312 and the second connecting rod groove 322, so that the tethering ring 5 can be firmly fixed in the track structure and ensure the safety of the tethering ring 5 in use.

[0021] To facilitate the movement of the tethering ring 5 within the track structure and to improve the securing effect of the tethering ring 5, for example... Figure 2 As shown, the movable card holder 51 is connected to the first card holder groove 311 and the second card holder groove 321 by clearance fit; the connecting rod 53 is connected to the first connecting rod groove 312 and the second connecting rod groove 322 by clearance fit.

[0022] To facilitate the movement of the tether ring 5 within the track structure, for example... Figure 4As shown, the movable card holder 51 is in the shape of a cuboid or a cylinder, and its material is preferably alloy steel.

[0023] To facilitate the processing and manufacturing of the tethering ring 5, the fixed ring 52 and the connecting rod 53 are integrated into one structure. During processing and manufacturing, the upper half of a steel bar is bent into a ring to form the fixed ring 52, and the lower half of the steel bar forms the connecting rod 53.

[0024] To facilitate the use of the machine tie ring 5, the connecting rod 53 is vertically mounted on the movable bracket 51 via a thread. This arrangement allows the fixed ring 52 and the connecting rod 53 to be replaced according to different machine models, ensuring the effectiveness of the machine tie ring 5.

[0025] To facilitate the installation of the tethering ring 5 in the track structure, for example... Figure 1 As shown, one of the circular track grooves 31 has a tethering ring at each end, which is placed into the circular groove 313.

[0026] In summary, by setting a track structure on the track steel plate base 3 of the landing pad, the tethering ring 5 is movably installed in the track structure and can move to any position along the track structure. This allows the tethering ring 5 to meet the needs of different aircraft models for different fixing points. It can also be flexibly combined and replaced according to the size, weight and other parameters of the aircraft model, realizing the fixing of multiple aircraft models and significantly improving the adaptability of the landing pad wind-resistant fixing system. Furthermore, the landing pad of this invention includes a concrete base 1, a fixed steel plate base 2, a track steel plate base 3 and a concrete counter-pressure fixing base 4. The fixed steel plate base 2 and the track steel plate base 3 are first processed in the factory and then installed on site, which facilitates the construction of the landing pad. The concrete counter-pressure fixing base 4 reinforces the track steel plate base 2 with counter-pressure, improving the overall strength of the landing pad and effectively improving the stability and durability of the landing pad, which is conducive to large-scale use.
