Embodiment Construction

[0015] like figure 1 , 2 , 3, the central part of the plane bottom plate 1 of the present invention is provided with an electromagnetic device, which is composed of a "Π" shaped magnetic core 2 and parallel coil turns 21 wound on the two columns of the magnetic core. An upper cover plate 3 is arranged on the upper part of the electromagnetic device, and a spring column 4 is arranged on the outer four corners. The spring column is centered on the guide rod 41 connecting the upper cover plate 3 and the plane bottom plate 1, and the guide rod sleeve 42 and its sleeve seat 43 are arranged on the outside. The spring 44 is sleeved outside the sleeve 42 and stands upright on the sleeve seat 43. superior. The magnetic core of the electromagnetic device is made of silicon steel sheet material with high magnetic flux, and its upper part is clamped by channel steel 22 on both sides and connected to the upper cover plate. The lower part of the permeable core 2 and the plane bottom plat...

Abstract

The invention discloses a plate type electromagnetic vibration compacting machine. The tamping machine overcomes the shortcomings of the existing diesel engine and electric motor as the power device that the tamping machine is prone to failure, short working life, and heavy weight. The electromagnetic device is composed of parallel coil turns on the two columns of the permeable core, and the electromagnetic device is controlled by an electric circuit mainly controlled by a single-chip microcomputer to control the frequency conversion of the thyristor. Under the action of the controlled electric circuit, the magnetic core of the electromagnetic device will attract and detach with the flat bottom plate at a frequency to achieve the purpose of compaction. The invention can adjust the frequency, amplitude and impact force of the compaction vibration, so it is suitable for construction under different working conditions, and is especially suitable for the compaction of road and bridge subgrade concrete and the maintenance of road surfaces. It has the advantages of high host energy utilization rate, no pollution, simple structure, low failure rate, low noise, small weight of the whole machine, quick and light transition, etc.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a flat-plate electromagnetic vibrating compactor used in engineering construction. Background technique [0002] As we all know, the construction of roads, ports, municipal administration, water conservancy or national defense construction is inseparable from tamping machines. For the construction medium, such as: earth-rock filling and laying layer mixture materials need to be compacted. Therefore, the tamping machine is an essential mechanical equipment for handling the foundation of buildings or structures. In the prior art, the power device of the impact tamping machine or the vibrating tamping machine is mostly driven by an internal combustion engine or an electric motor to drive the rotation of the eccentric wheel, and the exciting force generated by the eccentric wheel is used to transmit it to the bottom plate through the wheel shaft to realize the constructio...
