Embodiment Construction

[0020] Such as figure 1 As shown, the present invention discloses a hoisting process of a full-slewing crane, the steps of which are as follows:

[0021] (1) Lifting of components: Use 1600T floating crane double hooks to hang the slewing chassis and the assembly lifting lugs on the top of the herringbone frame. The four assembly lifting lugs on the slewing chassis are integrated by the Q690E high-strength plate with a thickness of 40mm at the hinge point of the slewing chassis , the weighted plate is formed, and the required components are blanked as a whole during the numerical control; the assembly lugs on the top of the herringbone frame are the luffing hinge point lugs and hinge point shafts on the top of the herringbone frame, and the original parts are used as the lifting lugs, which are safe Reliable, without additional processing; hoist the rotary chassis 4 and herringbone frame 5 components, slowly tension the hoisting wire rope, hoist the rotary chassis 4 and herrin...

Abstract

The invention relates to a hoisting process of a full-circle slewing crane. The hoisting process mainly comprises the following steps: component lifting: double hooks of a 1600T floating crane are utilized to hang a slewing chassis and a final-assembled lifting lug at the top of a propeller strut so as to hoist the slewing chassis and a propeller strut component; hoisting in place: the floating crane is utilized to shift the component to the position above a spud leg, and the component is adjusted in place; the component is slowly laid down onto a cylinder body, and all double-end studs can penetrate in place; after some of bolt pairs are pre-tightened, the floating crane can release the hooks, and all the bolt pairs are pre-tightened subsequently; mounting of remaining parts. The hoisting process has the advantages that a slewing bearing and all the slewing parts are mounted in place, integrally hoisted in place on site and connected with the cylinder body, so that the workload of site mounting is greatly reduced, and the mounting progress is accelerated.

Description

technical field [0001] The invention relates to a large hoisting device, in particular to a hoisting process of a full-slewing crane. Background technique [0002] Such as figure 1 As shown, the full-slewing crane mainly includes a jib 1, a jib shelf 2, a cylindrical body 3, a slewing chassis 4, a gable 5 and a supporting connector at the bottom. The supporting connector is provided with a cylindrical body 3, a rotary chassis 4, and a gable frame 5 from bottom to top. The top of the gable frame 5 is connected with an arm frame 11, and the arm frame 1 is inclined to one side of the cylinder body 3 and other components. The shelf 2 is supported at the bottom of the jib. [0003] In the past, the hoisting steps of the full-slewing crane were basically divided into two hoistings according to the order of the arrangement of the components. However, this method has a large amount of on-site installation work and slow installation progress. Contents of the invention [0004] T...
