Embodiment Construction

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below in conjunction with the drawings in the embodiments of the present invention.

[0024] Such as figure 1 As shown, the plug-in helicopter maintenance pedal of the present invention includes two parts of the support pedal 10 and the left and right slide rails. The left and right slide rails are fixed on the load-bearing structure of the fuselage (such as the bulkhead 40, the beam 50, and the fuselage skin 11) by riveting, and the support pedal 10 is inserted and removed according to maintenance requirements along the left and right slide rails by pulleys.

[0025] Such as figure 2 As shown, the left slide rail 10 includes a left rail 13 composed of a lower limit rib 11 and an upper limit rib 12 parallel to each other, and a left limit portion 14 is provided at the ...

Abstract

The invention relates to a plug-type helicopter maintenance pedal and belongs to helicopter structural designs. The plug-type helicopter maintenance pedal comprises a first slide rail, a second sliderail and a supporting footboard, wherein the first slide rail is provided with a first track consisting a first limiting rib and a second limiting rib that are mutually parallel, and a first limitingpart is arranged at one end part of the first limiting rib to restrict rollers from sliding; the second slide rail is provided with a second track consisting of a third limiting rib and a fourth limiting rib that are mutually parallel, a second limiting part is arranged at one end part of the third limiting rib to restrict the rollers from sliding, and the second slide rail and the first slide rail are symmetrical; and the supporting footboard is of an arc-shaped structure, a skin is arranged on an arc-shaped side, a diametral plane is a pedal face, not less than two roller sets are arranged on two sides of the pedal face, a certain distance is kept between the roller sets, and axes of the rollers are parallel to the pedal face. The internal space is fully utilized, the pedal is plugged and maintained according to maintenance requirements, defects of a conventional fixed pedal are avoided, and aerodynamic configuration is not influenced.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and in particular relates to a plug-in type helicopter maintenance pedal. Background technique [0002] The maintenance pedal is an integral part of the helicopter structure, and its main function is to provide boarding access for on-board equipment maintenance. The pedals are required to provide maintenance personnel with a convenient boarding channel, make full use of the space inside the aircraft, and meet the maintenance requirements of the equipment. When the pedal adopts a fixed form, it needs to be installed on the outside of the skin, and it will affect the aerodynamics, the layout space of the external equipment, and the appearance. The use of plug-in maintenance pedals, which can be plugged and unplugged from the inside of the fuselage according to maintenance requirements, can make good use of the space inside the aircraft and maintain the beautiful and complete ae...
