Description

Sinking type helicopter wheel fixing device

Technical Field

The utility model relates to a sinking type helicopter wheel fixing device, and belongs to the technical field of wheel fixing devices.

Background

The existing large ships and offshore platforms are provided with helicopter decks, so that marine transport of materials and manpower transportation are facilitated. Due to the large seaborne storms, after the helicopter falls onto the deck, the helicopter's wheels need to be firmly secured to the deck to prevent the helicopter from moving on the deck, which would otherwise be very dangerous in the case of storm.

However, the existing helicopter decks are all a plane, the helicopter decks are only provided with fastening points and wheel blocks, when the helicopter is stopped, the fastening points on the surfaces of the decks are used for fixing, because the helicopter is high in strength requirement, the number of fastening points is large, the construction cost is high, and meanwhile, many matched parts such as butterfly buckles, tension belts and the like are needed for binding, but due to the fact that the helicopter is urgent in lifting time, improper operation is easily caused, the tethers are unstable, the wheel blocks are needed to be placed in front of and behind the wheels after the tethers, the operation is very troublesome, a large number of ground staff are needed for fixing and releasing the helicopter in lifting, and the risk of cable breakage is also caused in the case of high wind waves.

Disclosure of Invention

The present utility model aims to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

The technical scheme provided by the utility model is as follows: the utility model provides a submerged helicopter wheel fixing device, includes deck, supporting seat, actuating cylinder and layer board, set up the recess on the deck, the supporting seat is located the below of deck, the actuating cylinder includes cylinder body and piston rod, the cylinder body is fixed on the supporting seat, the layer board is horizontal to be installed the piston rod stretches out the one end of cylinder body, drives through the extension of piston rod the layer board is in go up and down in the recess.

Further, a ground lock for locking and securing the wheel to the deck is included, the ground lock being mounted to the deck.

Further, the ground lock is a chain type ground lock.

Further, a sealing ring is arranged in the groove and is close to the upper end face of the deck.

Further, the driving cylinder is a hydraulic cylinder, an air cylinder or an electric cylinder.

Further, the supporting seat is an I-shaped structural beam arranged below the deck.

Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects: the utility model makes a sinking design on the deck, can lead the wheels of the helicopter to be directly fixed in the deck, and simultaneously uses the ground locking device to firmly fix the wheels of the helicopter on the deck, thereby reducing the cost of a fastening point and leading the fixation of the helicopter to be firmer.

in the figure, 1, deck; 2. a support base; 3. a drive cylinder; 4. a supporting plate; 5. a groove; 6. a cylinder; 7. a piston rod; 8. a ground lock; 9. a seal ring; 10. and (3) wheels.

Detailed Description

The principles and features of the present utility model are described below in connection with examples, which are set forth only to illustrate the present utility model and not to limit the scope of the utility model.

As shown in fig. 1, the submerged helicopter wheel fixing device comprises a deck 1, a supporting seat 2, a driving cylinder 3 and a supporting plate 4, wherein a groove 5 is formed in the deck 1, the supporting seat 2 is located below the deck 1, the driving cylinder 3 comprises a cylinder body 6 and a piston rod 7, the cylinder body 6 is fixed on the supporting seat 2, the supporting plate 4 is horizontally arranged at one end of the piston rod 7, which extends out of the cylinder body 6, and the supporting plate 4 is driven to lift in the groove 5 through the expansion and the contraction of the piston rod 7.

In addition, in the present embodiment, the present utility model,

the securing device further comprises a ground lock 8 for locking and securing the wheels 10 to the deck 1, said ground lock 8 being mounted on the deck 1. The ground lock 8 is a chain type ground lock 8.

A sealing ring 9 is arranged in the groove 5, and the sealing ring 9 is arranged close to the upper end face of the deck 1. When the pallet 4 is moved to lie on the same level as the deck 1, the pallet 4 forms a flat deck 1 surface with the deck 1, and the sealing ring 9 prevents water from flowing into the recess 5 from the gap between the pallet 4 and the deck 1.

In this embodiment, the driving cylinder 3 is a hydraulic cylinder, and the driving cylinder 3 may be a cylinder or an electric cylinder. The supporting seat 2 is an I-shaped structural beam arranged below the deck 1, and the structural beam can bear the weight of the helicopter.

The working method of the wheel fixing device of the utility model is as follows:

the deck 1 is provided with a front wheel groove 5 and a rear wheel groove 5, a supporting seat 2, a driving cylinder 3 and a supporting plate 4 are arranged in the groove 5, and when the helicopter is not stopped on the deck 1 at ordinary times, the supporting plate 4 is lifted to be positioned on the same horizontal plane with the deck 1 by the hydraulic cylinder, so that the helicopter is not different from the common deck 1. When the helicopter is required to land and stop on the deck 1, the front wheel and the rear wheel of the helicopter are moved to the respective supporting plates 4, then the hydraulic cylinders are started, the piston rods 7 of the hydraulic cylinders drive the wheels 10 to descend into the grooves 5 through the supporting plates 4, so that the helicopter is in a sinking state after stopping on the deck 1, the wheels 10 can be prevented from moving back and forth and left and right, and then the wheels 10 are locked by the chains on the ground lock 8, so that the helicopter is fixed.

The utility model has the advantages that the sinking design is carried out on the deck 1, the wheels 10 of the helicopter can be directly fixed in the deck 1, and meanwhile, the ground lock 8 device is used for firmly fixing the wheels 10 of the helicopter on the deck 1, so that the cost of a fastening point is reduced, and the helicopter is more firmly fixed.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
