Title:
HAMMERING DEVICE
Document Type and Number:
Japanese Patent JP2018124064
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hammering device 1 for performing a hammering inspection on a concrete wall or the like 61 by moving a ferromagnetic body 12 inserted into a solenoid coil 14 and by controlling the electricity flowing through the solenoid coil 14 so as to move the ferromagnetic body 12.SOLUTION: The hammering device 1 is characterized in that the ferromagnetic body 12 is supported at a position of a central axis 16 of the solenoid coil 14 by an elastic body 18. Since the ferromagnetic body 12 does not contact an inner wall of the solenoid coil 14 by the elastic body 18, no sliding sound is generated as compared with the case where the ferromagnetic body 12 slides in contact with the inner wall of the solenoid coil 14. In addition, the impact when the ferromagnetic body 12 hits the concrete wall or the like does not generate an impact sound that transmits directly to the inner wall of the solenoid coil 14.SELECTED DRAWING: Figure 1
