the installation crawler 4 is a piece for installing large pieces of tippler equipment, and the installation crawler 4 does not enter the area defined by the column 3 of the tippler factory building due to site reasons;
the lengthened seat 5 of the maintenance bridge crane II is a piece arranged on a crane cart and used for supporting the distance between two adjacent cranes, and is provided with a buffer 7 on the bridge crane 2 and a rotatable hinged connecting rod hinge point 6 on the maintenance bridge crane 2;
the hinged point 6 of the rotatable hinged connecting rod on the maintenance bridge crane 2 is arranged above the lengthened seat 5 of the maintenance bridge crane 2, and can be hinged or opened with the rotatable hinged connecting rod 9 on the maintenance bridge crane 1 to realize separation or combination of the cranes;

the lengthened seat 8 on the maintenance bridge crane I is a piece arranged on the crane cart and used for supporting the distance between two adjacent cranes, providing a buffer surface for the buffer 7 on the bridge crane II 2 and installing the rotatable hinged connecting rod hinge point 10 on the maintenance bridge crane I1;
the rotatable hinged connecting rod 9 on the maintenance bridge crane I1 is arranged above the lengthened seat 8 of the maintenance bridge crane I1 and hinged with the hinged point 10 of the rotatable hinged connecting rod on the maintenance bridge crane I1;
the hinged point 10 of the rotatable hinged connecting rod on the maintenance bridge crane I1 is arranged above the lengthened seat 8 of the maintenance bridge crane I1, and the rotatable hinged connecting rod 9 on the maintenance bridge crane I1 is hinged with the hinged point and can rotate around the hinged point by power;
in another connection mode, a coupler I11 and a coupler II 12 are respectively arranged on the lengthened seat 5 of the maintenance bridge crane II and the lengthened seat 8 of the maintenance bridge crane I, and the two couplers can be connected and opened.
Working principle:
moving a maintenance bridge crane II 2 covering the CD3 and the CD4 into a factory building span covering the CD1 and the CD2 maintenance bridge crane I1;
the state of the same-span maintenance bridge crane I1 and maintenance bridge crane II 2 working respectively (see figures 3 and 4):
the rotatable hinged connecting rod 9 on the maintenance bridge crane I1 rotates around the hinged point 10 of the rotatable hinged connecting rod on the maintenance bridge crane I1 and turns over to be positioned above the lengthened seat 8 of the maintenance bridge crane I1 shown in figure 3; or, the coupler I11 or the coupler II 12 on the bridge crane I1 and the bridge crane II 2 are maintained to be opened;
when two adjacent maintenance bridge cranes I and II are close to each other, a buffer 7 on the bridge crane II 2 contacts with the end face of an extension seat 8 on the maintenance bridge crane I1, the distance between the two cranes is controlled, the distance between the two adjacent bridge cranes and the center line of the wheel distance C between the two closest wheels on the inner side of the adjacent bridge crane is ensured, and the sum of the distance between the two closest wheels on the outer side of each maintenance bridge crane and the center line of the wheel distance C between the two closest wheels is larger than the distance A between the two adjacent factory building upright posts; and the distance B between the nearest two wheels on the inner side of the same-span adjacent bridge crane is larger than the wheel tread C of the innermost side of each maintenance bridge crane.
Therefore, in the moving process of the maintenance bridge crane I1 and the maintenance bridge crane II 2, the pressure born by each plant upright 3 is basically not larger than the pressure of the maintenance bridge crane I1 or the maintenance bridge crane II 2 to each plant upright 3, so that the plant upright 3 does not need to be increased.
The state of simultaneous operation of the maintenance bridge crane I1 and the maintenance bridge crane II 2 (see FIGS. 4 and 6):
the rotatable hinged connecting rod 9 on the power-driven maintenance bridge crane I rotates around the rotatable hinged connecting rod hinge point 10 on the maintenance bridge crane I1, turns over to be positioned above the lengthened seat 5 of the maintenance bridge crane 2 shown in fig. 4 and is hinged with the rotatable hinged connecting rod hinge point 6 on the maintenance bridge crane II 2;
after hinging, the two-part maintenance crane forms a large bridge crane through a rotatable hinging connecting rod hinging point 6 on a maintenance bridge crane II 2, a rotatable hinging connecting rod 9 on a maintenance bridge crane I and a rotatable hinging connecting rod hinging point 10 on the maintenance bridge crane I;
due to the adoption of the hinge mechanism, the wheel pressures generated by hoisting of the maintenance bridge crane II and the maintenance bridge crane I are basically not mutually influenced; in the running process of the maintenance bridge crane II and the maintenance bridge crane I, the problem of asynchronism can not cause the stress deflection of the hoisted object.
After the bridge cranes are combined, the distance between the distance B between the nearest two wheels on the inner sides of adjacent bridge cranes and the center line of the wheel tread C on the outermost sides of the bridge cranes is larger than the distance A between the adjacent plant columns; after the bridge cranes are combined, the distance B between the nearest two wheels on the inner sides of adjacent bridge cranes which are same across is larger than the wheel distance C on the innermost side of each maintenance bridge crane, so that the pressure born by each factory building upright post 3 is basically not larger than the pressure born by each maintenance bridge crane 1 or each factory building upright post 3 by each maintenance bridge crane 2 in the process of moving the cart of the bridge crane consisting of the maintenance bridge crane 1 and the maintenance bridge crane 2, and the factory building upright posts 3 do not need to be increased.
Thus, after the large piece is transferred to the near CD1 equipment accessory through the crawler crane 4, the large piece can be transferred to the middle CD2 line accessory by the bridge crane consisting of the maintenance bridge crane I1 and the maintenance bridge crane II 2, and all large piece hoisting operations are completed; in the same span, the maintenance bridge crane I1 and the maintenance bridge crane II 2 can be controlled to work respectively, and the load of the upright post of the factory building can be ensured to be basically unchanged when the maintenance bridge crane I and the maintenance bridge crane II work respectively.
After the large part is lifted, the maintenance bridge crane connecting rod 5 is removed, and the maintenance bridge crane II 2 is moved into the span of the dumper CD3 and CD4, so that the purpose of lifting the overweight parts is achieved without increasing the specification and the number of the lifting crawler crane and the maintenance bridge crane and reinforcing a factory building.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
