modified tower

[ector]

Hey, guys.
my daily problem is the design of a sort of telescope that I need to connect to a vehicle and command via remote control from within the same.This telescope must rotate in azimut and zenit performing complete movements of one or more corners turn.
a little like the theodolites, but all controlled with a system (electric, electromechanical, electrohydraulic....boo) remote of the interior of the car by remote control.
Do you have any idea how to do this? Some straight? my problem is the cables because if it turns at the end they will cling and it is not good....

Help!

Help!

for example, that in the axis c of 5-axis machine tools are used by rotary distributors that allow continuous rotations while transmitting signals from encoders, motor power, spindle etc.
a thing like thishttp://www.ltn-servotechnik.it/content/collettori-rotanti.htm

Okay, but maybe we'd better get something easier. . . or do you have any material to study? I don't know. .

 

[stefanobruno]

How many signals do you have to carry in rotation and what kind?

Bye.

I think if you don't know anything, you'll have to inform yourself. . I think you have no other solution. See that it is less complex than it seems. If you call a supplier (e.g. wampfler, vahle, sae, etc...) they give you a collar that looks like a flange box on one side to which you have to apply a drag on the rotating part, nothing simpler.
electrical data (number and amperage of electrical channels, number of channels for data).
In several cases I have designed ad hoc for particular applications and it is nothing but.
in this case you need an electric designer to size your contacts.
you will probably also need an axis encoder to control the position and bring it directly into the manifold. . .
In short, we should see the application.

contact someone, if you enter "rotating charges" google find the world.

the simplest you make a splash with some circular lead tracks and some "coal" that crawls over us like those of the blenders; they sell them as exchanges to a few euros...
by force, that if you provide more precise information and form the questions in a clear way maybe someone who helps you find it also, otherwise if we become so we want the crystal peel... :wink:

Hi.

I have seen the answers of others now. but for which arcane mystery bosogna always tear with the big cloths the basic information they serve to understand what caspita they need... help? :redface:

 

[zeigs]

If you use something similar to convoy waves, only contact is enough. or even better via radio: with the contact sends current, the mass does the carcass, the rest is the control unit that receives the commands via radio. But in both cases it takes a power station, I don't know if you're in it with cost and size.
If you don't have to do more than two or three laps you can safely use a couple of untight cable coils, maybe drowned in the fat or wrapped in a morbid protection, it will survive quietly to stress. Obviously in that case it takes something that limits the turns. There are tricks that allow you to do even twenty laps without stressing the cable, but in my opinion you do much earlier to buy something commercial so go on the safe.
However rereading it is not necessary for force an electric drive inside the tower: to transmit the motion of zenit you can think of a ralla that can move along the axis of rotation that commands a lever: moving the raddle along the axis tilts the "telescope", while to rotate, well, turn the axis. but actuators always remain in the same position

Hi.

 

[ector]

How many signals do you have to carry in rotation and what kind?

Bye.

two I believe...one for azimutale rotation and one for zenithal

 

[ector]

Then I could do this:
1-mix the supporting rod (the vertical one) with at the base a conical pair that I connect to a scooter, in the head the telescope and the problem of rotation in azimut is solved.
2-for zenit how do you recommend me to do?

Consider that from the inside of the vehicle I must have the bridge of the comadi always in one position. where I control both rotations.

important!I forgot that on the telescope I also have to put a dot (solidal to the telescope) to turn on and turn on command too.

I thought I'd do the quarry auction and make the contacts pass inside, but cmq the wire tangles after a tot of turns...

What a scratch:::frown::frown::

 

[stefanobruno]

with two signals control nothing unless they are:

1) with variable analog value depending on the position.
2) with data packet transmission.

ps. : I am not an expert on all existing technologies.

it would also be interesting to understand the degree of accuracy you have to get.
In addition, if it is clear that you have to make more spins, do you have the same need or the angle is reduced?

What size and weight are we talking about?

Bye.

 

[ector]

for horizontal to vertical zenit (90°), the weight is at least 50-60 kg only of the turret.
Okay, I understand I'm abandoning the idea of electronics....cmq is the problem I have to solve, maybe I do everything hydraulic? What do you say? an effective, simple and functional slim solution. ....
importantly, I have no cost problems, so whatever proposal for me is fine.

thank you guys for the immense help

 

[stefanobruno]

still lacks the precision value.

to move such a limited zenit you could insert in the rotating hollow shaft a rod with axial stroke, with a toothed top (a sort of round rack ) that fills in a spool.

I understand. ..good idea of the racket and racket. . .

 

[stefanobruno]

I understand. ..good idea of the racket and racket. . .

Do you have to stop in a position with tolerance +/- 0.1° or +/- 3°?
Or are you moving on?

Bye.

( Now let's go to sleep that morning approaches)

ok, only this last info, the accuracy is good also of + or 1° but the important is the game in oscillation (zenit) which must be almost null.. .
Thank you so much again.
start having the clearest ideas

not really, I would like to find something more crude, in the sense with very little electronic and almost all mechanical. .

then you have to go back in time.http://www.aeroplanemonthly.co.uk/aeroarchive/aeronautical_engineering_news_70090.htmlbaulton pauls were the most compact and simple.

the Germans were lovers of electric servo-commands, the Americans departed with the tire the English had arrived to the plumbing.

Regardless of the type of energy the command was always mechanical (pignone crown or chain) with servomotor (electric, hydraulic or pneumatic).

Hydraulic was the easiest to govern at that time, today the electronics makes the electrical control unsurpassed, the tire is only cheap.

for the game there are a number of "trucks" all valid, but you must first decide which drive to use.

the factors are many, the weight of the mass in rotation, the accelerations (inertias), and the environment (temperature, wind etc.).

Everything is possible and remember that all we think is already done, we have to put ourselves in the head that a museum is better than empty years pushed into our university classrooms.

p.s.: one of the greatest builders of turrets made in use was the kelvinator who took the patent from another English, the nash (the one of the frazer nash).
interesting is the fact that the major military builders (American and also Japanese) were also the biggest washing machine manufacturers (ge, philco, kelvinator, etc.).

But how many do you know about this 50-year-old exile?
