specific Embodiment approach

[0022] Taking the 3500 square cutter suction dredger as an example, the specific implementation method is as follows: including the following steps:

[0023] S1. When the bridge section 1 is built, the main part of the bridge section 1 is installed, and the end of the bridge section 1 is installed with the trunnion sleeve 22 to separate two independent sections 2, and the bridge section 1 is installed with the trunnion sleeve 22 The bottom of the end is vacant, as in figure 1 shown.

[0024] S2. Assemble the two independent sections 2. During the assembly process of the independent section 2, install the trunnion sleeve 22 into the independent section 2. During the assembly process of the independent section 2, install the trunnion sleeve 22 into the independent section. In the section 2, the independent section 2 is assembled separately, the operating space is not limited, the construction environment when the trunnion sleeve 22 is installed is improved, and the construction...

Abstract

The invention discloses a cutter suction dredger bridge trunnion sleeve mounting method, and relates to the technical field of cutter suction dredger machining. The cutter suction dredger bridge trunnion sleeve mounting method comprises the following steps that when a bridge segment is constructed, a main body part of the bridge segment is installed, and the end, provided with trunnion sleeves, ofthe bridge segment is separated into two independent segments; the two independent segments are assembled, and in the independent segment assembling process, the trunnion sleeves are installed in theindependent segments; and the two independent segments and the bridge segment are folded, the two independent segments are installed at the vacant position of the end, provided with the trunnion sleeves, of the bridge segment, and bottom plates of the two independent segments correspond to the bottom of the bridge segment. The cutter suction dredger bridge trunnion sleeve mounting method has theadvantages that the two independent segments are separated from the end part, provided with the trunnion sleeves, of the bridge segment, in the independent segment assembling process, the trunnion sleeves are installed in the independent segments, the independent segments are independently assembled, the operation space is not limited, the construction environment is improved when the trunnion sleeves are installed, construction is convenient, and the requirement for installation precision can be met.

Description

technical field [0001] The invention relates to the technical field of cutter suction dredger processing, in particular to a method for installing a bridge trunnion sleeve of a cutter suction dredger. Background technique [0002] There is a slot in the front half of the cutter suction dredger, and a bridge frame is arranged in the slot, and the front end of the bridge frame is equipped with a reamer head for cutting equipment for digging soil. When dredging, put down the bridge frame, place the reamer on the head at the bottom of the channel to be dug, start the mud pump, and rotate the reamer to loosen the underwater soil to form mixed mud. The bridge trunnion sleeve is the key part connecting the hull and the bridge frame, and the bridge frame is directly installed on the bridge trunnion seat of the hull through the bridge trunnion sleeve. The bridge frame can be rotated around the bridge trunnion to meet the needs of different dredging depths. The installation of bridg...
