The invention discloses a mounting method for a quay crane upper component. The mounting method comprises the steps that a jig frame is provided, and a rear girder is arranged on the jig frame; a sea-side upper cross beam and a land-side upper cross beam are provided and are mounted in the corresponding positions of the rear girder respectively; the levelness of the rear girder is adjusted with the center lines of the sea-side upper cross beam and the land-side upper cross beam as the horizontal reference; welding is performed after it is ensured that the distance between the central lines of the sea-side upper cross beam and the land-side upper cross beam meets the design requirement; a trapezoidal frame is mounted on the sea-side upper cross beam of the rear girder; welding is performed after it is ensured that the perpendicularity of the trapezoidal frame relative to the ground, the perpendicularity of the trapezoidal frame relative to the center line of the rear girder and the perpendicularity of the trapezoidal frame meet design requirements; a rear supporting rod is mounted to be connected with the trapezoid frame and the rear girder; a rear girder pull rod system is mounted; a front girder is connected with the rear girder, and the center line of the front girder and the center line of the rear girder are adjusted to meet the design requirements; a front girder pull rod system is mounted; and the quay crane upper component is integrally hoisted to a quay crane door frame structure.
Description
technical field [0001] The invention relates to the field of container hoisting, in particular to a method for installing an upper component of a shoreside container crane. Background technique [0002] The upper assembly of the quayside container crane mainly includes components such as the front girder, the rear girder, the ladder frame, the rear strut, the machine room, the front girder tie rod system, and the rear girder tie rod system. , welding or high-strength bolts and other methods of assembly. [0003] In the existing technology, due to the errors in the structural manufacturing and assembly process of each component, the accumulation of various errors may cause the reinforcement plate of the support of the machine room to not correspond to the main girder partition, and the centering deviation of the front girder and the rear girder , Over-tolerance of girder track height difference and over-tolerance of tie rod stress, etc. These problems will increase the diffi...
