Abstract:
A filling apparatus of insulation material, comprising:a vibration means made up of a vibration plate element vibrating buried in the insulation material supplied between the internal and external walls of a super low-temperature storage tank, a lower plate connected to attach and detach the upper part of a shaft of the vibrating plate element, a vibrator for generating the vibration installed on the lower plate and furthermore vibrating the vibrating plate element via the lower plate, and an upper plate for covering the vibrator, connected to the lower plate through a plurality of vibration buffering elements and having a rolling element to enable of rotation by a plurality of support shafts; a lift driving means made up of a winding motor, a drum revolving by the winding motor, and a wire wound up on the drum wherein the lower part of the wire is wound up on the rolling element of the vibrating means so as to drive the vibrating means along with the ratio of winding the wire; a horizontal transporting means wherein a pair of rollers are installed to transport by a transport motor without digression in slide along a guide rail attached on a bracket on a ceiling of the storage tank and rolling at a certain intervals supported by the first, second and third support frames, the first to third support frames working continuously with a connection frame; an automatic winding means interlocked to the second support frame of the horizontal transporting means at one side of the lift driving means, one end of its cable being wound up on a winding roll and the other end of its cable being connected to the vibrating means; a level sensing means connected to the third support frame of the horizontal transporting means on the other side of the lift driving means and controlling the filling amount of the insulation material filled in a spacious part between the internal and external walls of the storage tank; a flux preventing means made up of a bracket attached to the lower and upper plates of the vibrating means to project out and upwardly and a tamping roller shaft-supported to revolve on an end part of the bracket and buffering the collision impact between the internal and external walls of the storage tank as well as maintaining in stability the horizontal flux and verticality of the vibrating means; a descending position sensing means placed lower than the vibrator on both sides of the vibrating means and restricting the descending position of the vibrating means by touching the insulating material; a controlling means for checking the filling amount of the insulation material filled by a signal received from the level sensing means and thereby remote-controlling the driving means, the horizontal transporting means and the vibrator; and a display means made up with a camera integrated with the vibrating means, a lighting lamp and a monitor capable of a direct observation of the inside through the camera from outside of the storage tank.
