Title:
SHOT BLAST DEVICE FOR WALL SURFACE
Document Type and Number:
Japanese Patent JPS63260766
Kind Code:
A
Abstract:

PURPOSE: To enable a wall surface to be shot blasted pressing a seal of a shot blasting mechanism to the wall surface and preventing shot material from scattering, by resiliently supporting the shot blasting mechanism to a lift truck, provided in a guide frame, so that the shot blasting mechanism is able to longitudinally move performing a follow-up motion on the wall surface.

CONSTITUTION: A gondola 1 is lifted to a predetermined position on a wall surface S, thereafter if a guide frame is extruded to the front by manual work, the guide frame advances through turning arms 11, 13 while maintaining this condition by a one-way clutch 13. In accordance with the above, a shot blasting mechanism 24 on a lift truck 21 presses a seal 26 and a wheel 28 to the wall surface S by repulsive force of a compression coil spring 23 completely sealing clearance between the wall surface and the shot blasting mechanism 24. under this condition, the shot blasting mechanism 24 is driven blasting shot material to the wall surface S while lowering the lift trunk 21 at a low speed. The mechanism 24, even if the wall surface S provides some ruggedness, performs a follow-up motion of the seal 26 to this ruggedness preventing the slot material from flying to the outside.
