Technical Field
[0001] The utility model belongs to the field of aviation equipment, and particularly relates to an anti-skid deck for an apron. Background Art
[0002] The apron deck is an important facility for aircraft take-off, landing and docking, and its anti-skid performance is directly related to flight safety. Traditional anti-skid methods for apron decks mainly rely on coatings or anti-skid materials. However, these methods have problems such as unstable anti-skid effect, easy wear, and high maintenance costs. Therefore, it is of great practical significance to develop an anti-skid deck for apron decks that has good anti-skid effect, is durable, and is easy to maintain. Utility Model Content
[0003] The utility model aims to solve the above problems in the prior art and proposes an anti-skid deck for a helipad.
[0004] In order to achieve the purpose of the innovative utility model, the following technical solutions can be used:
[0005] A helipad anti-skid deck comprises a plate-like main body, wherein the plate-like main body is fixedly connected to the helipad via a supporting seat, and the plate-like main body is provided with a toothed structure and a hole-digging structure for anti-skid.
[0006] The upper end surface of the plate-like body of the utility model is formed with a bearing surface for bearing the helicopter, and the toothed structure and the hole-digging structure are arranged on the bearing surface, which are used to increase the friction between the plate-like body and the helicopter, improve the anti-skid performance, and ensure the stable take-off and landing of the helicopter; and compared with traditional anti-skid treatment methods such as coating anti-skid paint or applying anti-skid layer, the plate-like body is directly fixed on the apron through a support seat to achieve stable installation, which is convenient to install and also helps to reduce subsequent replacement and maintenance costs.
[0007] In the above-mentioned anti-skid deck of the helipad, the toothed structure includes a plurality of anti-skid protrusions arranged on the plate-like body, and the anti-skid protrusions are distributed on the plate-like body at intervals in a matrix.
[0008] The tooth structure is realized by anti-skid convex bodies, which are arranged at intervals on the bearing surface of the plate-like body and are used to directly contact the landing gear of the helicopter, which is equivalent to forming rough lines on the plate-like body, increasing the friction between the landing gear and the landing gear, and having a good anti-skid effect. The specific distribution form can be matrix distribution, uniform distribution, and of course other suitable distribution methods can also be used.
[0009] In the above-mentioned anti-skid deck of the apron, the anti-skid protrusions are in a straight line shape, and their cross sections are in one or more combinations of triangles, rectangles, trapezoids, etc.
[0010] The anti-slip convex body is straight and easy to process. The cross section can be set to various shapes that are conducive to increasing friction. The setting forms are diverse. Among them, the triangular cross section is preferred. While ensuring the increase in friction, the shape of small on the top and large on the bottom increases its load-bearing stability and is not easy to tip to one side.
[0011] In the above-mentioned anti-skid deck of the apron, the anti-skid convex body is integrally formed on the plate-shaped body;
[0012] Alternatively, the anti-slip protrusion is welded and fixed on the plate-shaped body;
[0013] Alternatively, the anti-slip protrusion is arranged on the plate-like body through a detachable structure.
[0014] As for the specific connection method between the anti-skid protrusion and the plate-like main body, the main purpose is to fix and stabilize; as a first setting method, the anti-skid protrusion is integrally formed on the plate-like main body by other feasible methods such as die-casting, and the overall structural strength is large; as a second setting method, the anti-skid protrusion is subsequently welded and fixed to the plate-like main body, which is conducive to setting the corresponding density according to specific needs and is flexible in implementation; as a third setting method, the anti-skid protrusion is detachably arranged on the plate-like main body. On the basis of having a good fixing effect, the detachable connection method is conducive to replacing the anti-skid protrusion of suitable shape and parameters at any time, and is also conducive to timely replacement of severely worn anti-skid protrusions. It is highly practical and ensures a good anti-skid effect.
[0015] In the above-mentioned anti-skid deck of the helipad, the detachable structure includes a plug-in column vertically fixed to the lower end of the anti-skid protrusion and a plug-in hole vertically opened on the plate-like body, and the plug-in column is inserted in the plug-in hole.
[0016] The plug-in column extending downward from the anti-skid convex body is inserted into the plug-in hole to achieve plug-in installation. It is detachable and easy to disassemble and assemble. As an optimization, the inner diameter of the plug-in hole and the outer diameter of the plug-in column are adapted to each other, that is, the plug-in column and the plug-in hole are tightly fitted and fixed, eliminating or almost eliminating unnecessary deviation of the anti-skid convex body. Furthermore, an external thread can be provided at the lower end of the plug-in column, and a nut is engaged with the external thread to form a vertical limit.
[0017] In the above-mentioned anti-skid deck of the apron, the hole-digging structure includes a plurality of anti-skid holes evenly distributed on the plate-like body, the anti-skid holes are vertically opened on the plate-like body, the anti-skid holes include through holes and / or blind holes; the anti-skid holes include one or more combinations of circular, elliptical, and polygonal shapes.
[0018] The hole-digging structure achieves an anti-skid effect by setting an anti-skid hole on the plate-like body. The anti-skid hole is concave, which increases the roughness of the bearing surface and has a good anti-skid effect on the helicopter landing gear. The anti-skid hole can be a through hole or a blind hole. Of course, the through hole is preferred. On the one hand, it is easy to process. On the other hand, the depth is greater and the roughness is higher. The specific shape of the anti-skid hole can be set in a variety of ways, and the setting is flexible. Among them, the circular shape is preferred for easy processing.
[0019] In the above-mentioned anti-skid deck of the helipad, the anti-skid hole is a through hole, a water guide structure is arranged below the anti-skid hole, and the water guide structure is located between adjacent support seats.
[0020] When the anti-skid hole is set through, rainwater or other debris will fall onto the apron below through the anti-skid hole. Since most of the apron area is covered by the plate-like body, water vapor is not easy to dissipate, and equipment corrosion and other problems are prone to occur. The water guide structure is docked and set below the anti-skid hole to discharge the flowing rainwater in time and increase the service life of the equipment.
[0021] In the above-mentioned anti-skid deck of the apron, the water guide structure includes an inclined water guide trough plate, the water guide trough plate is placed on a transversely arranged support rod, the support rod is arranged below the plate-like body, and the arrangement path is inclined toward one end; the support rod is inserted into the connecting hole of the support seat; or, the support rod is connected to the plate-like body through a vertically arranged connecting rod, the upper end of the connecting rod is fixedly connected to the plate-like body, and the lower end is fixedly connected to the end of the support rod.
[0022] The water guide trough plate is arranged below the plate-shaped body through a support rod, and is inclined, which is conducive to timely drainage of rainwater. Moreover, the water guide trough plate is arranged on the support rod by placing, and can be easily pulled out, which is convenient for timely replacement of the water guide trough plate or timely cleaning of debris accumulated on the water guide trough plate, and maintenance, repair and replacement are very convenient. As for the arrangement of the support rod, the support rod can be fixed to the lower end surface of the plate-shaped body through a connecting rod, that is, the connecting rod and the support rod form a U-shaped or Π-shaped structure, and the water guide trough plate is arranged in its opening, and the connection is stable; as another solution, a connecting hole is opened on the support seat, and the support rod is inserted into the connecting hole to achieve stable fixation, which is convenient to implement.
[0023] As a feasibility optimization of the connecting hole, the connecting hole is a blind hole, and the end of the supporting rod is inserted into the blind hole; as another feasibility optimization of the connecting hole, the connecting hole is a through hole, and the supporting rod is arranged through the connecting hole.
[0024] As an optimization, at least one U-shaped limiter with an opening downward is provided at the lower end of the water guide plate, and the U-shaped limiter and the connecting rod cooperate to form a limit in the length direction of the water guide plate. The U-shaped limiter is connected to the connecting rod to achieve a limit effect, thereby avoiding the problem of the water guide plate falling out due to vibration and other reasons.
[0025] In the above-mentioned anti-skid deck of the helipad, the support seat is straight and has an inverted T-shaped cross-section. The upper end of the support seat is fixedly connected to the lower end surface of the plate-like body, and the mounting portion extending laterally at the lower end is fixedly connected to the mounting surface of the helipad through a mounting structure.
[0026] The support seat is fixed to the lower end of the plate-shaped body, and the lower end surface of its mounting portion is attached to the mounting surface of the apron, and is fixed therebetween through the mounting structure. The mounting portion is horizontally extended, that is, has a certain width, which is conducive to the setting of the mounting structure and also to increasing the contact area with the mounting surface. The mounting structure is common knowledge and will not be elaborated here.
[0027] In the above-mentioned anti-skid deck of the apron, the surface of the plate-like main body and the anti-skid convex body of the tooth-like structure are sprayed with an anti-corrosion and wear-resistant coating. Another purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a.
[0028] An anti-cover and wear-resistant coating is sprayed on the plate-like main body and the outer surface of the anti-skid convex body to improve corrosion resistance and wear resistance and extend the service life of the equipment. As an optimization, the main part of this anti-skid deck is made of aluminum profiles, which itself has good corrosion resistance and wear resistance.
[0029] Compared with the prior art, the utility model mainly has the following advantages:

[0045] Specifically, the tooth structure 2 is realized by the anti-skid protrusion 21, which is arranged at intervals on the bearing surface of the plate-like body 1, and is used to directly contact the landing gear of the helicopter, which is equivalent to forming rough lines on the plate-like body 1, increasing the friction between the landing gear and the landing gear, and has a good anti-skid effect. The anti-skid protrusion 21 is integrally formed on the plate-like body 1 by other feasible methods such as die casting, and the overall structural strength is large. The specific distribution form can be a matrix distribution, which is evenly distributed. The anti-skid protrusion 21 is linear, easy to process, and has a triangular cross-section. On the basis of ensuring the increase of friction, the shape of small on the top and large on the bottom increases its load-bearing stability and is not easy to tip to one side.

[0047] Specifically, the hole-digging structure 3 achieves the anti-slip effect by setting anti-slip holes 31 on the plate-like main body 1. The anti-slip holes 31 are concave, which increases the roughness of the bearing surface and has a good anti-slip effect for the helicopter landing gear.
