Description

Technical Field

[0001] The utility model relates to the technical field of airport manhole covers, in particular to a heavy-duty load-bearing continuous manhole cover used in airports. Background Art

[0002] In modern transportation, airplanes have become an important means of mainstream rapid transportation. Taking an airplane or transporting goods by airplane can achieve the transportation purpose in a short time. Airports are necessary supporting facilities for airplanes and are important places for aircraft operation, maintenance, repair, passenger transfer and cargo transfer. Usually, airports require a large area for passengers and cargo to stay, as well as for airplane parking, takeoff and landing.

[0003] In rainy weather, whether the runway can drain water quickly is an important part of ensuring the safety of aircraft takeoff and landing. Once the weather conditions are bad and the precipitation is heavy, if water accumulates on the runway, flights will be affected. In order to ensure the drainage efficiency of the runway, the drainage outlet on the airport runway is usually built longer, thereby increasing the size of the drainage outlet to improve the drainage efficiency of the runway. However, when the length of the drainage outlet is lengthened, the bearing capacity of the manhole cover will be weakened, and the service life of the manhole cover will be reduced. Utility Model Content

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a heavy-duty load-bearing continuous manhole cover for airports.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a heavy-duty load-bearing continuous manhole cover for airports, including a manhole cover group, the manhole cover group includes a manhole cover plate, the front and rear sides of the manhole cover plate are respectively detachably equipped with support seats, the bottom of the manhole cover plate is provided with a plurality of groups of drainage grooves, and the top of the drainage grooves is provided with drainage holes.

[0006] Furthermore, a first wedge-shaped surface is provided on the front and rear sides of the manhole cover, the bottom end of the first wedge-shaped surface is inclined toward the inner side of the manhole cover, and a second wedge-shaped surface matching the first wedge-shaped surface is provided on the side of the support seat close to the manhole cover, and a support platform is provided at the bottom of the second wedge-shaped surface.

[0007] Furthermore, a threaded hole is opened in the middle of the support platform, and a countersunk hole corresponding to the position of the threaded hole is opened on the manhole cover plate. A fastening bolt is installed in the countersunk hole, and the manhole cover plate is fixedly connected to the support seat by the bolts.

[0008] Furthermore, a groove is provided on the side of the support seat away from the manhole cover plate, connecting holes are provided on the left and right side walls of the support seat, and a plurality of groups of reinforcing ribs are provided between the top wall and the side walls of the groove.

[0009] Furthermore, the manhole cover groups are spliced ​​together to form a drainage manhole cover.

[0010] The beneficial effect of the utility model is that the design scheme of the utility model is designed to open a plurality of groups of drainage grooves at the bottom of the manhole cover, and grid-like reinforcing ribs are formed between the side walls of the drainage grooves, thereby improving the compressive strength of the manhole cover. In addition, the manhole cover is supported by a support seat. When a heavy object presses over the manhole cover, the vibration of the manhole cover is reduced, and the stability of the manhole cover on the ground is improved, thereby reducing the impact force on the manhole cover, and further increasing the service life of the manhole cover.

DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0019] according to Figure 1-5As shown, a heavy-duty load-bearing continuous manhole cover for airports includes a manhole cover group 1, which includes a manhole cover plate 11, and support seats 12 are detachably installed on the front and rear sides of the manhole cover plate 11. A plurality of drainage grooves 111 are provided at the bottom of the manhole cover plate 11, and drainage holes 112 are provided at the top of the drainage grooves 111.

[0020] In this embodiment, a first wedge-shaped surface 113 is provided on the front and rear sides of the manhole cover 11, and the bottom end of the first wedge-shaped surface 113 is inclined toward the inner side of the manhole cover 11. A second wedge-shaped surface 121 matching the first wedge-shaped surface 113 is provided on the side of the support seat 12 close to the manhole cover 11, and a support platform 122 is provided at the bottom of the second wedge-shaped surface 121. When the manhole cover 11 is installed on the support seat 12, the bottom surface of the manhole cover 11 is supported by the support platform 122, and the first wedge-shaped surface 113 and the second wedge-shaped surface 121 squeeze each other to eliminate the installation gap between the support seat 12 and the manhole cover 11, thereby improving the stability of the manhole cover 11 installed on the support seat 12.

[0021] In this embodiment, a threaded hole 123 is opened in the middle of the support platform 122, and a countersunk hole 114 corresponding to the position of the threaded hole 123 is opened on the manhole cover 11. A fastening bolt 2 is installed in the countersunk hole 114, and the manhole cover 11 is fixedly connected to the support seat 12 by bolts.

[0022] In this embodiment, a groove 124 is provided on the side of the support seat 12 away from the manhole cover 11, and connecting holes 125 are provided on the left and right side walls of the support seat 12. By providing the groove 124 on the side of the support seat 12, the materials required for the production of the support seat 12 are reduced, and the splicing between the support seats 12 is facilitated. A plurality of groups of reinforcing ribs 126 are provided between the top wall and the side wall of the groove 124. The preferred number of reinforcing ribs 126 is three groups. By arranging the reinforcing ribs 126 in the groove 124, the compressive strength of the support seat 12 is improved.

[0023] In this embodiment, the manhole cover groups 1 are spliced ​​together to form a drain outlet manhole cover 3. When installing the drain outlet manhole cover 3, the manhole cover groups 1 of different lengths are spliced ​​together according to the length of the drain outlet, so that they are suitable for drain outlets of different lengths, thereby improving the versatility of the product.

[0024] The specific usage process of the utility model is as follows. First, support seats of different lengths are spliced ​​and installed on both sides of the drain outlet according to the length of the drain outlet. Then, the bolts are passed through the connecting holes 125 and tightened by nuts to fix the adjacent support seats together. Then, the manhole cover 11 is installed on the corresponding support seats 12 respectively and fixed by tightening the bolts 2. The support platform 122 supports the bottom surface of the manhole cover 11. The first wedge surface 113 and the second wedge surface 121 squeeze each other to eliminate the installation gap between the support seat 12 and the manhole cover 11, thereby improving the stability of the manhole cover 11 installed on the support seat 12. When a heavy object presses over the manhole cover 11, the vibration of the manhole cover 11 is reduced, and the stability of the manhole cover 11 on the ground is improved, thereby reducing the impact force on the manhole cover 11 and thereby improving the service life of the manhole cover 11.
