Control method of pile holding machine

Abstract

The invention provides a control method of a pile holding machine. The pile holding machine comprises a base, a pile holding device, an oil cylinder device and a locking device are arranged on the base, the pile holding device comprises a holding arm, a bearing seat and an open arm oil cylinder, the bearing seat is installed on the base, the holding arm is connected with the bearing seat, and theopen arm oil cylinder is connected with the holding arm and the base; and the locking device comprises a locking oil cylinder, a fixing base, a lock pin, a locking fixing plate and a movable fixing plate, the locking oil cylinder is installed on the locking fixing plate through the fixing base, and a piston rod of the locking oil cylinder is arranged in the fixing base and connected with the lockpin. According to the structure, when the holding arm is closed, a pile is pre-fixed through idler wheels of the oil cylinder device, meanwhile, the pile holding device is locked through the locking pin, the movable fixing plate and the locking fixing plate by driving the locking oil cylinder, so that the pile is surrounded, the holding arm is closed firstly and then locked, and the operation method is simple while the stability is ensured.

Description

technical field [0001] The invention relates to the technical field of offshore operations, in particular to a control method for a pile holding machine. Background technique [0002] One of the difficulties in offshore construction is the installation of piles. Using a pile hammer to forcefully strike the piles and insert them into the underwater mud, that is, the so-called "pile driving". To ensure the verticality of the pile, therefore, it is necessary to use a pile holder to balance the verticality of the pile during the piling process. [0003] In the patent document with the Chinese patent application number 201710038038.1 and the publication date of 2017.05.10, an offshore wind power operation platform is disclosed, which includes a positioning pipe frame, and an operation console is installed on the positioning pipe frame, and at least A group of pile-holding mechanisms are installed; the pile-holding mechanism includes two positioning plates symmetrically arranged,...

Problems solved by technology

[0004] However, when the pile-holding mechanism of this invention is holding the pile pipe tightly, there is a large gap between the pile-holding mechanisms. Therefore, in the process of piling, the pile pipe will vibrate. If the swing oil cylinder breaks down and the swing arm Loosening will cause the pile pipe to break away from the pile holding mechanism, which may cause serious harm
