The utility model discloses simple structure, low cost, simple to operate can realize the effect of braking to the active cell of low-speed motion, to the active cell of high-speed motion, can play auxiliary brake and protection active cell and orbital effect.
Description
Technical Field
The utility model relates to a buffering protection device for bilateral rail mounted catapult, the catapult that is particularly useful for high-speed motion is to active cell and orbital protection when the quick braking.
Background
The unmanned aerial vehicle catapult is driven by the rotor to accelerate to realize short-distance take-off of the fixed-wing unmanned aerial vehicle, the high-speed rotor after acceleration needs to realize short-distance braking, and a hydraulic buffer or a rubber pad is usually installed at the tail part of the catapult to serve as a tail end braking buffer device. However, the energy absorbed by the hydraulic buffer and the rubber buffer is limited, when the kinetic energy of the rotor is large, the buffer device at the tail end is not enough to brake the rotor, and at the moment, the rotor easily collides with the rail, so that the ejector is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem of improving the defects of the prior art, provides a buffer protection device for a bilateral track type ejector with simple structure and strong applicability,
the utility model adopts the following technical scheme:
the utility model provides a bilateral rail mounted catapult active cell buffering protection device, includes the catapult support body, the inside both sides of catapult support body are provided with active cell buffering protection device, active cell buffering protection device is including fixing two relative elastic buffer layer in the inside both sides of catapult support body.
The elastic buffer layer is of a structure with a narrow front part and a wide back part.
The elastic buffer layer is made of rubber.
The outer side surface of the elastic buffer layer is fixed with a plurality of bolts, and the elastic buffer layer is fixed on the mounting hole on the side surface of the ejector rack body through the bolts.
The distance between the front ends of the two opposite elastic buffer layers is larger than the width of the rotor, and the distance between the rear ends of the two opposite elastic buffer layers is smaller than the width of the rotor.
The inner side surfaces of the two opposite elastic buffer layers are rough surfaces.
The utility model has the advantages that:
current buffer adopts the positive mode that directly strikes and inhale the ability, causes the damage to the catapult active cell easily, compares with current buffer, the utility model discloses increase the mode of both sides rubber slab, carry out the buffering of slowing down to the active cell in advance to when the active cell strikes terminal buffer, protect active cell and catapult support body. The utility model discloses simple structure, characteristics such as low cost, simple to operate can realize the effect of braking to the active cell of low-speed motion, to the active cell of high-speed motion, can play auxiliary brake and protection active cell and orbital effect.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a bilateral rail mounted catapult active cell buffering protection device, this buffering protection device include catapult support body 9, and catapult support body 9 is inside to have the motion slide that makes active cell 5 pass through, and the both sides of catapult support body 9 internal slide set up active cell buffering protection device, and active cell buffering protection device includes first elastic buffer layer 6 and second elastic buffer layer 7, and two elastic buffer layers set up the end at catapult support body 9 internal slide relatively.
In one or more possible embodiments, the elastic buffer layer is a structure with a narrow front part and a wide back part, the structure is preferably a right trapezoid structure or a right triangle structure, the elastic buffer layer structure comprises an outer side 2 and an inner side 3, the outer side 2 is attached to the inside of the ejector frame body 9, the inner side 3 is arranged oppositely, and in order to ensure the effect, the side surface of the inner side 3 can be arranged as a rough surface.
The interval of two relative elastic buffer layer front ends 1 is greater than the width of active cell 5, and the rear end interval is less than the width of active cell, and from front end 1 promptly, two elastic buffer layer slowly become thick, and the interval slowly diminishes, guarantees that the active cell enters into two elastic buffer layer, reaches the purpose that the buffering slows down through elastic buffer layer's structure.
In order to ensure the reliable connection of the elastic buffer layer and the ejector frame body 9, a plurality of bolts 4 are fixed on the outer side 2 of the elastic buffer layer, a plurality of connecting holes 10 are formed in the side face of the ejector frame body 9, and the bolts 4 penetrate through the connecting holes 10 and then are fixed through nuts 8 to fix the elastic buffer layer and the ejector frame body 9 together.
The elastic buffer layer is made of the existing elastic material, such as the existing rubber material. The length, the thickness and the material of the elastic buffer layer can be adjusted according to different requirements of the ejection task. Bolt fastener and elastic buffer layer mounting hole adopt standardized design, are convenient for change elastic buffer layer.
The utility model discloses at the during operation:
the mover 5 impacts the buffer protection layers at a certain speed, and after the mover 5 enters the space between the two buffer protection layers, the mover 5 is extruded by the buffer protection layers on the two sides because the distance between the buffer protection layers is smaller than the width of the mover 5, so that deceleration braking is started. Because the buffering protective layer material is softer, consequently, can not cause the damage to active cell 5 at buffering braking in-process, simultaneously, when active cell 5 and catapult support body bump, play the cushioning effect, protection active cell and slide.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the present invention should be covered by the protection scope of the present invention.
