Description
Technical field
A kind of straight line catapult-launching gear of the utility model, belongs to catapult-launching gear technical field.
Background technology
Ejector is mainly used for military aspect at present, and the ejector of comparative maturity is steam catapult, and the cylinder that cracks is close
Envelope is core technology, which requires traction shuttle freely movable at cylinder place of cracking, and can seal in time
The shortcomings that high steam in cylinder, steam catapult, is more, mainly there is, standard too big in the forward and backward stage acceleration difference of ejection
The standby time is too long, and air accumulator and control system are too complicated, and volume is too big, weight is too big, energy utilization rate is too low, fresh water consumption
Too big, maintaining maintenance load is too big, and the cycle of operation is longer, and Braking system mechanism is complicated and needs to occupy longer distance
Etc..
Electromagnetical ejector is more advanced than steam catapult, but since technical barrier is too many, also fails to input practical application, it is said that
95.36 meters of linear electrical captain, latter end have 7.6 meters of deceleration buffer braking area；Using flywheel and large-scale generator rotor energy storage.
The shortcomings that Electromagnetical ejector is also that energy is stored in a manner of mechanical energy it will be apparent that be to need powerful power supply first,
It needs in the very short time of electric energy, huge electric energy is converted mechanical energy by dynamotor, then utilize linear motor will be electric
It can be converted into mechanical energy, this series of conversion, not only technical sophistication, corollary equipment is numerous and jumbled, bulky, and cost is very high, and
And it is uneconomical, for example, being intended to reach maximum 490,000,000 burnt ability of ejection energy involved in the present invention, 2.1 seconds time is launched, is needed
The power supply of 400000 kw of power, followed by electric energy will produce a large amount of heat during being converted into mechanical energy, not only handle
It bothers, itself is also the performance of inefficiency, and on human body and electronic equipment there is great influence in magnetic field actually, it is also necessary to put into practice
It examines, mover shuttle inertia is huge, and not only braking is difficult, and after need to resetting, and follow-up aircraft can be in place, in war conditions
Under, how the reliabilities of a large amount of electronic components ensures etc., many problems need to solve, existing steam catapult and electromagnetism
Ejector manufacturing expense is too high, and use cost is too high, it is difficult to accomplish something at civilian aspect.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of simple in structure, at low cost, using effect
Good straight line catapult-launching gear.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of straight line catapult-launching gear, including
Ejection platform and power unit, power unit are arranged below ejection platform, and power unit includes that three groups of staggered parallels are arranged
Chain drive, chain drive include fixed seat, are provided with transmission shaft in fixed seat, on transmission shaft from left to right successively
It is provided with sprocket wheel, a pair of of gear-box, brake block, multiple motors is provided with by the gear-box, is provided with below gear-box solid
Fixed board is provided with chain on sprocket wheel, and ejection sliding block is provided in ejection platform, and ejection sliding block is connected with three groups of chains.
The gear-box is symmetrical above and below to be provided with multigroup motor.
Branch sleeve is provided between the gear-box, the motor is uniformly arranged on sleeve outer surface.
The straight line catapult-launching gear further includes controller, and controller is connected with motor, brake block.
The utility model has the advantages that compared with prior art：The use of chain drive is main power source, knot
Structure is simple, and power source is stablized, and transmission mechanism is run with rotating manner, is conducive to the transmission of energy, the inertia of geartrain components
It is limited to rotate, there is no linear inertia is cut down, is conducive to the braking of system, is substantially shorter ejection and occupies distance, letter
Changed drive mechanism, mitigated mechanism weight, reliability is high, and power is transmitted ratio and answered, and small, manufacturing cost is low, efficient, run at
This is low, safeguards simply, can be widely applied to military, civilian aspect.
