What are the mechanisms?
Nowadays there are three types of opening of street gates:
- swinging;
- recoiling;
- garage.
Swing - it's a classic look. The gates consist of two gates, which are attached to the vertical base on the hinges, a deep and firmly installed steel frame. To manually or automatically open the doors, you need space in front of them.
If you want to make automatic swing gates to give yourself, we recommend you watch this video:
Roll-back on rollers, usually one leaf, a technically simple design, as the weight of the gate is distributed to the rollers, and to withstand wind and lateral loadsadditional guides are installed. Such mechanisms are difficult to operate, but at the same time it is quite easy to make a mechanical part with your own hands.
If you are interested in this option of automatic gates for fencing, we recommend you review this video review:
. The garage shuttle type is a set of figured rails made of metal-plastic, linked by a movable lock, placed in guide grooves and connected in one structure. Moving through the grooves, they break through the ceiling in the castle, thereby overcoming the right angle, and the gate rails go under the ceiling, freeing the entrance to the garage.
The garage lifting and turning type makes a complex maneuver, going up and clearing the passage. The automatic lifting mechanism is difficult to install and operate.
Principle of operation
The mechanism for opening swing gates is a set of two motors and an automation system that monitors the position of the wings and the sequence of their opening / closing. The leaf with the groove profile-groove must start the movement first, with the automatic opening of the gate and finish the movement of the last when closing. Also, the movement should stop at the extreme points of the position of the leaflets. The power of the motors depends directly on the weight of the wings - the heavier, the more powerful the motor and gearbox are needed to manage them. It is also worth considering the area of the canvas, the effect of wind on them. This will add extra load to the motors. It is better to provide and make an emergency opening of the street gate, in case of a breakdown or lack of electricity, in manual mode, removable.
In both factory and homemade drives, the actuator is mainly used, which is depicted in the photo below:
It is a threaded pin with a screw coupling on it. Due to the rotation of the pin, the coupling is wound on the thread, thereby moving along the stud.
The reduction ratio depends on the thread pitch, the smaller the step, the more force the actuator can transmit. As an electric motor, you can use a motor reducer for car wipers or window lifters.
The mechanism of automatic sliding gates is quite simple in implementation. One motor, one reducer. The transfer of linear motion can be on the rack with the teeth, or the motorcycle chain. Automatics monitors the extreme positions of the sash, closed or open. The main highlight is the rigid design of the leaf and the system of rollers holding this structure during closing and opening. It also provides side load resistance during the wind. The main task is to make sure that the balanced leaf easily and effortlessly goes along the rollers and guides. During the development of the gate, emergency opening should be provided, in the event of a breakdown or power outage. As an el. It is also possible to use the engine from the window regulator or wipers.
Garage automatic gates, in turn, are divided into roller shutters( they can also be called sectional) and lifting and turning. This type of problematic to do yourself because of the complexity of production technology. Their plus is that the manufacturing takes place on an individual order in the shop, and the installation is carried out by the whole unit, therefore it does not take much time.
The result of
Now the market offers a wide range of mechanisms and elements so that you can make automatic gates with remote opening and closing yourself.
In our article, we tried to introduce the reader to the existing types of mechanisms and suggest an idea for self-selection of the appropriate option for a country house, indicating the points to which you need to pay more attention:
- Sailing. Resistance to wind.
- Weight. Load on the opening mechanism.
- Emergency opening in manual mode. Ease of implementation.
- Suitability of repair and ease of maintenance.
We hope, now you know how to make automatic gates with your own hands and what the mechanism should consist of. If you liked the material, why not share it with your friends in social networks?
