The vibrating plate is one of the type of equipment necessary for construction work. It is intended for compaction of various surfaces - sand, a mixture of gravel and crushed stone when laying roads, loose soil. Vibrating plates are divided into gasoline - devices that operate on the basis of the operation of the internal combustion engine, as well as electric, which operate by charging from an alternating current source.
The device of an electric vibrating plate
The electric vibrating plate has several main details:
1. The working part is directly the plate tamping the surface.
2. Electromechanical vibrator with circular vibrations. This part is installed in the central part of the stove and is an asynchronous three-phase electric motor. At the ends of the shaft of its squirrel-cage rotor, unbalances are located. It is they, rotating in the same way as the rotor, that create a directed force.
3. The control handle. This element is mounted on the frame using special vibration isolators, and the frame is attached to the plate.
The surface is densified by a vertically directed driving force generated in the vibrator. The translational movement of the electric plate produces due to the horizontally acting force.
To change, if necessary, the force of action of the plate on the surface to be treated, you need to change the angle between the two parts of the unbalance at each end of the shaft. Imbalances consist of two equivalent parts - mobile and motionless. Depending on the distance between them, the force of action of the plate changes.
Vibrating plates are divided into translational and reverse plates - depending on the principle of operation.
Translational vibrating plates
Vibrating plate electric translational action is also called single-pass. She only moves forward. Such devices are used for work on small objects, where there is enough room for maneuvers, that is, the room must be of the correct shape, without protrusions and many turns.
Reversible vibrating plates
The electric reversible vibrating plate has a high resistance to the action of abrasive materials.
With the help of double adjustment, the compaction work can be carried out both when moving forward and backward, as well as in one place. Such a vibrating plate copes well on soils of varying degrees of connectivity. The machine has excellent maneuverability, suitable for working in tight spaces. Another advantage is the low noise level.
Acquisition of a vibrating plate
An electric vibrating plate, the price of which depends on the principle of operation, can be either bought or rented. The acquisition of the plate is advisable for large volumes of construction work, where compaction of the soil is mandatory. This, for example, the work of road services. At enterprises with a different profile of activity, first of all, completely different equipment is used, and electric vibrating plate is additional. Renting this equipment from specialized organizations in this case would be the best option.
