The specific embodiment
Below in conjunction with Fig. 3～Fig. 8, describe a preferred embodiment of the present invention in detail.
As shown in Figure 3, inner sleeve rolling wheel for mounting device provided by the present invention is used for inner sleeve 2 is assembled in the evaporator shell 1, and it comprises: some axial roller devices 4 and a circumferential roller devices 5; Some described axial roller devices 4 are fixedly mounted on the small end place of inner sleeve 2, and center on the circle spacing setting of inner sleeve 2; The installation site of each axial roller devices 4 must not arrange support pin 3 along inner sleeve 2 axially extended projected position places, be that axial roller devices 4 is crisscross arranged along inner sleeve 2 axial directions with support pin 3, thereby so that each axial roller devices 4 all can not run into stopping of support pin 3 on the path of carrying vertically inner sleeve 2; Described circumferential roller devices 5 is arranged on the circumferential bottom position between inner sleeve 2 and the evaporator shell 1; The bottom of this circumferential roller devices 5 is curved, is complementary with the inwall of evaporator shell 1.
As shown in Figure 5 and Figure 6, described axial roller devices 4 comprises axial some axial roller 42 with support 41 and longitudinal arrangement; Each axial roller 42 is arranged on axial bottom with support 41 by an axial roller shaft 43 respectively; Each axial roller shaft 43, drives axial roller 42 and rotates with all adopting an axial bolt 44 to be fixedly connected with between the support 41 with axially to prevent axial roller shaft 43 from moving.
In the present embodiment, axially roller devices 4 comprises the axial roller 42 of two longitudinal arrangements.Certainly, the present invention also can be according to the weight of inner sleeve 2, and correspondence arranges more axial rollers 42, to strengthen the bearing capacity of axial roller devices 4.
As shown in Figure 5, described axial top with support 41 arranges a groove 46, and the high wall thickness with inner sleeve 2 of its groove is complementary; As shown in Figure 4, the barrel insertion at inner sleeve 2 small end places is axially used in the groove 46 of support 41, and by bolt 45 axial roller devices 4 is fixedly mounted on the inner sleeve 2.
As shown in Figure 7 and Figure 8, described circumferential roller devices 5 comprises circumferential with support 51 and transversely arranged some all way rollers 52; Each all way roller 52 is arranged on circumferential top with support 51 by a circumferential roller shaft 53 respectively; Each circumferential roller shaft 53, drives all way rollers 52 and rotates with all adopting a circumferential screw 54 to be fixedly connected with between the support 51 with circumferentially to prevent circumferential roller shaft 53 from moving.
In the present embodiment, circumferentially roller devices 5 comprises two transversely arranged all way rollers 52.Certainly, the present invention also can be according to the weight of inner sleeve 2, and correspondence arranges more all way rollers 52, to strengthen the bearing capacity of circumferential roller devices 5.
As shown in Figure 7, described circumferential bottom surface 55 with support 51 is curved, is complementary with the inwall of evaporator shell 1 circumferential bottom position.
According to above-mentioned, below describe the concrete using method of inner sleeve rolling wheel for mounting device provided by the invention in detail.At first, small end place at inner sleeve 2, several axial roller devices 4 are fixed on the inner sleeve 2, and described axial roller devices 4 must be noted that around the circle spacing setting of inner sleeve 2 support pin 3 on each axial roller devices 4 and evaporator shell 1 inwall is crisscross arranged vertically.
Then, first inner sleeve 2 being carried out axial rolling carries, because the axial roller 42 of each axial roller devices 4 contacts with the inwall of evaporator shell 1, therefore, by external force inner sleeve 2 is sent in the evaporator shell 1 vertically, and in travel path, axially roller 42 can not run into stopping of support pin 3 on the evaporator shell 1.
After inner sleeve 2 axial conveyings put in place, again to its adjustment of circumferentially rolling.At this moment, circumferential roller devices 5 is placed on circumferential bottom position between inner sleeve 2 and the evaporator shell 1, because circumferentially the bottom surface 55 of roller devices 5 is curved, and be complementary with the inwall of evaporator shell 1, so it need not to carry out any fixing can use.
Because circumferentially all way rollers 52 of roller devices 5 contact with the outer wall of inner sleeve 2, therefore,, so that moving to adjust its installation site along circumferential direction, ends until the cross axis of inner sleeve 2 and steam generator is aligned to by inner sleeve 2 by external force.
In the process of actual installation inner sleeve 2, can constantly repeat the step that the axial and circumferential position is adjusted so that high-precision requirement is satisfied in the installation site of inner sleeve 2, install and fix complete after, with axial roller devices 4 and circumferentially roller devices 5 remove and get final product.
In view of above-mentioned, inner sleeve rolling wheel for mounting device provided by the present invention is with axial roller devices and circumferentially separately design of roller devices, so that simple in structure, easy to assembly; For the heavier heap type of inner sleeve, its bearing capacity of energy Effective Raise; Simultaneously on the operating path that inner sleeve is installed, can avoid running into stopping of support pin on the evaporator shell inwall, effectively simplify the assembly process of inner sleeve.
Therefore, use inner sleeve rolling wheel for mounting device provided by the present invention, can effectively simplify the installation procedure of inner sleeve, shorten the assembly period of inner sleeve, reduce simultaneously the manufacturing cost of man-hour, human cost and device.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
