Description

Technical Field

[0001] The utility model relates to the technical field of helicopter landing deck, and more specifically, to a spliced double-layer helicopter landing deck. Background Art

[0002] With the increasing status of helicopters in the national economy and national defense construction, the prosperity of public utilities will surely drive the development of the helicopter industry. At the same time, the development of the helicopter industry can also promote the progress of public utilities. To make the mobility of helicopters play more perfectly, more and more standardized helicopter pads are needed.

[0003] For example, the existing patent CN201420458943.4 discloses a spliced helicopter landing deck. By forming a snap-fit relationship between the flanges of adjacent two panels and the circular arc-shaped concave ring, on the basis of completing the connection of two panels, the circular arc-shaped concave ring provides a buffer margin, so that the deck has the ability to buffer the impact of helicopter landing on the basis of splicing, and the setting of heating cables forms the ability to melt snow, improving the adaptability of the deck to the helicopter landing environment. However, for this spliced helicopter landing deck, the snow on the anti-slip strips can be melted into snow water by the heating cables. Part of the snow water will drip from the edge of the deck, and the other part of the snow water will remain on the top of the deck, affecting the parking stability of the helicopter.

[0007] A spliced double-layer helicopter landing deck includes a frame and a support plate located at the inner top end of the frame. A transverse beam is arranged below the support plate. A number of uniformly distributed supporting blocks are arranged between the cross beam and the support plate. A drainage groove is formed at the top end of the supporting block. A drainage through hole axially arranged with a number of the drainage grooves is formed at the top end of the support plate.

[0008] Preferably, a receiving cavity is arranged in the frame and below the support plate. A hot air blower is arranged in the receiving cavity. An air outlet pipe of the hot air blower communicates with an air outlet pipe passing through the supporting block.

[0009] Preferably, a number of uniformly distributed supporting blocks are arranged in the receiving cavity. The top end of the supporting block is connected to the supporting block.

[0010] Preferably, positioning holes and positioning rods are respectively provided on both sides of the supporting block.

[0011] Preferably, clamping blocks and docking blocks are respectively provided on both sides of the frame.

[0012] Preferably, a first clamping groove and a second clamping groove are respectively formed on one side of the clamping block and the docking block close to each other, and the first clamping groove and the second clamping groove are clamped and spliced with each other.

[0013] Preferably, a hole is formed between the first clamping groove and the second clamping groove, and a self-tapping screw matched with the hole is provided on the frame.

[0014] The beneficial effects of the present utility model are as follows: Through the cooperative design of the hot air blower and the air outlet pipe, the hot air is gathered between the cross beam and the support plate, so that the snow on the top of the support plate can be melted into snow water, and the snow water enters the drainage groove through the drainage through hole and is discharged outwards, improving the stability of the helicopter landing; and through the cooperative design of the clamping block and the docking block, multiple groups of frames can be spliced, and are fixed by screwing the self-tapping screw into the hole.
