the inner container 101 is lifted by the crane 200, one end of the inner container 101 is placed on the moving vehicle 2, and the cylinder of the inner container 101 is supported by the support plate 21 of the moving vehicle 2;
the moving vehicle 2 moves towards the inner part of the outer cylinder 102 along the guide rail 1, and the inner container 101 is sleeved in the outer cylinder 102 by lifting the other end of the inner container 101 in cooperation with the travelling crane 200.
Further, reinforcing rings 1022 are annularly arranged on the inner wall of the outer cylinder 102 at intervals;
the registration method further includes, before installing the guide rail 1 in the outer cylinder 102:
the bottom of the plurality of reinforcing rings 1022 close to one end of the outer cylinder 102 is provided with an avoidance hole 1023, and the avoidance holes 1023 of the reinforcing rings 1022 are opposite;
when the guide rail 1 is mounted in the outer cylinder 102, the guide rail 1 is mounted in the escape hole 1023 and engaged and fixed with the reinforcing ring 1022.
Further, after the inner container 101 is nested in the outer cylinder 102, the method further comprises the following steps:
the inner container 101 is lifted up at both ends by the crane 200, and the guide rail 1 and the traveling vehicle 2 are removed.
According to the technical scheme, the embodiment of the invention at least has the following advantages and positive effects:
in the embodiment of the present invention, as can be seen from the above technical solutions, the embodiment of the present invention has the following advantages and positive effects:
in the registration device 300 of the embodiment of the invention, the registration device 300 is used for nesting the inner container 101 into the outer cylinder 102, the outer cylinder 102 is kept in a static state, and the inner container 101 is nested into the outer cylinder 102 under the driving of the registration device 300. The guide rail 1 can be detachably arranged in the outer cylinder 102, the roller 232 of the moving vehicle 2 is movably connected with the guide rail 1, the supporting plate 21 can support the cylinder of the inner container 101 and is matched with the travelling crane 200 for lifting the end socket of the inner container 101, the distance between the supported parts in the inner container 101 is shortened, and therefore the nesting stroke of the inner container 101 and the moving stroke of the moving vehicle 2 are shortened, the length of the guide rail 1 is reduced, the rigidity is improved, the guide rail 1 is arranged in the outer cylinder 102, the rigidity and the load capacity are improved under the support of the outer cylinder 102, the nesting device 300 can bear a tank body with a large specification, the universality and the simplicity of the nesting device 300 are high, and the manufacturing cost is low.
In addition, the support plate 21 is in an arc shape which is downwards concaved from two sides to the center, and the roller 232 is movably connected with the guide rail when in use and can be separated when not in use, so the nesting device 300 can be separated from the outer cylinder 102 after the inner container 101 is nested in the outer cylinder 102, for the inner container 101 which is adhered with the composite paper for heat insulation, the winding process of the inner container 101 for the heat insulation composite paper is that before the nesting process, the moving vehicle 2 and the inner container 101 are in a relative static state during the use, therefore, the moving vehicle 2 can not cause the damage of the heat insulation composite paper, and the outer layer protection of the inner container 101 is realized.
In the internal container 101 insulated by the pearlite sand, the filling of the pearlite sand is performed after the nesting step, and the internal container 101 is separated from the nesting device 300 in the pearlite sand filling step, and the nesting device 300 does not affect the filling of the pearlite sand in the internal container 101, so the nesting device 300 is not limited by the filling of the pearlite sand in the internal container 101 and the winding of the heat insulation composite paper.
The roller 232 is provided with a clamping groove 2321, and the clamping groove 2321 is fittingly clamped with the guide rail 1, so that the roller 232 is prevented from being separated from the guide rail 1 during the movement process.
While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
