Abstract
The invention belongs to the technology of a horizontal tail of a helicopter, in particular to a horizontal tail connection device for the helicopter. The horizontal tail connection device is provided with a fuselage connection joint, one side of the fuselage connection joint is combined and connected to a rear fuselage structure through a bolt, and double fork ears used for being connected with the horizontal tail are arranged at the top of the other side of the fuselage connection joint. The double fork ears are connected with mounting holes preformed in a girder of the horizontal tail through connecting bolts, connecting nuts and adjusting gaskets. The connection device capable of quickly dismounting and mounting the horizontal tail of the helicopter can dismount the horizontal tail only by manually dismounting the bolts without a large tool and is convenient to maintain the horizontal tail of the helicopter.
Description
Technical field
The invention belongs to helicopter horizontal tail technology, be specifically related to a kind of helicopter horizontal tail connecting device.
Background technology
Helicopter horizontal tail is generally the level of state and is arranged on tail, is horizontal stabilizer, plays the stable effect of pitching.Current most of helicopter all have employed to be arranged on tail boom by horizontal tail, and by tail boom being reserved the position, hole of horizontal tail aerofoil profile, the mode that then both sides respectively fill a bolt pinning fixes horizontal tail.This mounting means manufacture difficulty when the position, hole of reserved horizontal tail aerofoil profile is very large, and once almost can not dismantle after installing, necessary depot repair, manufactures maintenance cost high.Or by horizontal tail for becoming two parts, be riveted on the mode of vertical fin both sides respectively.This mounting means horizontal tail is a fuselage part inherently, non-dismountable.Must factory be returned during maintenance, must safeguard vertical fin structure simultaneously, waste time and energy.
Particularly be different from fixed wing machine horizontal tail, smaller and the space-closed of helicopter horizontal tail size, lowered in field environment is difficult to when damaging by external force ensure that original resonance frequency does not change by maintenance, therefore very easily produces potential safety hazard, causes adverse effect to flight safety.
Summary of the invention
The object of the invention is: provide a kind of can the connecting device of fast assembling-disassembling helicopter horizontal tail.
Technical scheme of the present invention is: a kind of helicopter horizontal tail connecting device, it has a fuselage jointing, this fuselage jointing side uses bolt combination to be connected in rear fuselage structure, opposite side top is provided with two pitch ear for what be connected with horizontal tail, and this pair of fork ear tie bolt, coupling nut, adjustment pad are connected with the mounting hole that horizontal tail girder is reserved.
A triangular support configurations is formed between this pair of fork basal part of the ear portion fuselage jointing.
Described triangular support configurations is hollow structure.
Bolt combination forms 3 strong points at fuselage jointing top, forms 2 strong points in fuselage jointing two bottom sides.
Advantage of the present invention is: helicopter horizontal tail connecting device of the present invention connects horizontal tail, during dismounting, do not need huge tool, by means of only artificial unloading's bolt and detachable horizontal tail, thus effectively avoid the error that Complex Assembly causes, and installation accurate positioning, type of attachment is simple, and the horizontal tail greatly facilitating helicopter is safeguarded.

Detailed description of the invention
Below the present invention is described in further details.
Refer to Fig. 1, helicopter horizontal tail connecting device of the present invention has a fuselage jointing 1, this fuselage jointing 1 side uses bolt combination 5 to be connected in rear fuselage structure, opposite side top is provided with two pitch ear for what be connected with horizontal tail, this couple of fork ear tie bolt 2, coupling nut 3, regulates pad 4 to be connected with the mounting hole that horizontal tail girder is reserved.Thus realize horizontal tail plug and play, avoid the error because Complex Assembly causes, and install accurate positioning, type of attachment is simple.
This fuselage jointing two fork is formed with a triangular support configurations between basal part of the ear portion, gains in strength to greatest extent.
Described triangular support configurations is hollow structure, effectively can alleviate structural weight.
Bolt combination 5 forms 3 strong points at fuselage jointing top, forms 2 strong points in fuselage jointing two bottom sides.Connect fuselage with bolt combination 5 be connected with helicopter fuselage rear beam by these 5 strong points.
During installation, extract tie bolt 2 out and tailplane inserted in the horizontal direction in two fork ears of fuselage jointing 1, plug tie bolt 2,2 tie bolts 2 be now inserted in the mounting hole that horizontal tail girder reserves play the effect of the pin of fixing horizontal tail, by behind the gap that regulates pad 4 elimination of level empennage and fuselage jointing 1, lock with coupling nut 3.
During dismounting, unload coupling nut 3, extract tie bolt 2 out, and tailplane is oppositely extracted in the horizontal direction, can tailplane be unloaded.
Helicopter horizontal tail connecting device of the present invention connects horizontal tail, during dismounting, does not need huge tool, by means of only artificial unloading's bolt and detachable horizontal tail, thus effectively avoid the error that Complex Assembly causes, and accurate positioning is installed, type of attachment is simple, and the horizontal tail greatly facilitating helicopter is safeguarded.
