The pile fixing frame structure constructing process comprises the following processes: blanking and cutting, assembling, rolling a cylinder, welding, prefabricating jig frames, scribing and controlling overall construction precision, constructing a gear rack lifting area structure, performing segmented assembling constructing on a pile fixing frame, and machining the pile fixing frame. The pile fixing frame structure constructing process has the advantages that the constructing process disclosed by the invention is realized through blanking and cutting, assembling, rolling the cylinder, welding, prefabricating the jig frames, scribing and controlling overall construction precision, constructing the gear rack lifting area structure, performing segmented assembling constructing on the pile fixing frame and machining the pile fixing frame in a constructing process of the pile fixing frame; and the construction is reasonable and accurate, rework is avoided, and the segmented making precision of the pile fixing frame is controlled, so that the construction quality is ensured.

Description

technical field [0001] The invention relates to a pile-fixing frame, in particular to a construction technique of a pile-fixing frame structure. Background technique [0002] The solid pile frame is a component closely connected with the pile legs, and is the carrier of the lifting device, which provides guidance for the lifting of the pile legs and plays the role of connecting the pile legs and the main hull. Due to its special purpose, its plates are mostly high-strength thick plates with compact structure and high precision requirements for segmentation. Many places need to be machined, and all of them are full-penetration structures. [0003] At present, the existing manufacturing process of the pile fixing frame usually has the following defects in the process of construction: 1. The accuracy of the cylinder is difficult in the process of rolling; 2. The vertical structure of the rack lifting area 3. It is difficult to control the accuracy of ground sample line scribin...
