Universal vibrator for concrete

Abstract

The invention discloses a universal vibrator for concrete. The universal vibrator comprises a vibrator shell, wherein one or more groups of bidirectional vibration electromagnets are arranged in the vibrator shell; each group of bidirectional vibration electromagnets comprises three bidirectional vibration electromagnets; and in each group, every two of the three bidirectional vibration electromagnets are vertical to each other on different horizontal planes, two ends of each of the two transversely arranged bidirectional vibration electromagnets are vertical to the wall of the vibrator shell respectively, and two ends of the longitudinally arranged bidirectional vibration electromagnet are vertical to the bottom of the wall of the vibrator shell; and the bidirectional vibration electromagnets are all connected with a power supply through a control circuit for generating different pulse signals. A worker can input pulse voltages with different frequencies and magnitudes into bidirectional vibration electromagnetic coils arranged in the vibrator shell to drive the bidirectional vibration electromagnets to work, so that the vibrator can vibrate and move towards an impact direction by using friction force of concrete; and furthermore, the concrete compactness can be improved, a higher vibration effect is achieved, and the work efficiency is improved remarkably.

Description

technical field [0001] The invention relates to a vibrator, in particular to a concrete universal vibrator. Background technique [0002] Concrete is a building material widely used in the construction industry. Since concrete contains a lot of gas and water after mixing, in order to make concrete reach its design strength, its compactness must be guaranteed. Equipment for improving the density of concrete. At present, the vibrator driven by the motor is widely used in the construction industry. It uses the alternating current power supply to drive the motor to rotate periodically, so that the concrete vibrating rod generates periodic vibration force to work, and its work is in the form of a stable rotating torque. Vibration requires a non-uniform periodic motion, so the existing vibrators cannot efficiently convert electrical energy into vibrating force, and cannot move by themselves during the vibrating process of large volumes of concrete, and rely entirely on manual ope...

AI Technical Summary

Problems solved by technology

At present, the vibrator driven by the motor is commonly used in the construction industry. It uses the AC power to drive the motor to rotate periodically, so that the concrete vibrating rod can generate periodic vibrating force to work, and its work form is a stable rotational torque. Vibration requires a non-uniform periodic motion, so the existing vibrator cannot efficiently convert electrical energy into vibrating force, and cannot move by itself during the vibrating process of large-volume concrete, relying entirely on manual operation Mobile, so the vibrating effect is poor, the work efficiency is low, and it is inconvenient to use

In addition, most of the existing vibrators work on the principles of planetary and eccentric, both of which will cause a large eccentric load on the rotating parts of the motor and reduce the service life of the equipment

[0003] The invention patent "A Plug-in Electromagnetic Vibrator" with the publication number CN2353829 and the "An Electromagnetic Vibrator" with the publication number CN2570378 respectively propose a vibrator and a vibrator that work on the electromagnetic principle, but Since the above two patents also use the periodic principle of alternating current to drive the electromagnet to work, they cannot efficiently convert electrical energy into vibrating force, and cannot move by themselves during the vibrating process of large-volume concrete, and can only rely on manual operation. Moving, the vibrating effect is poor, the work efficiency is low, and it is inconvenient to use
