Embodiment 1

[0028] Such as Figure 1 to Figure 3 As shown, the present invention provides an offshore platform pile pin insertion control system, including: pile legs 4, pile support brackets 3, a plurality of positioning pin holes 6 are distributed on the pile legs 4, and the control system also includes lateral anti-collision The bolt unit 2, the horizontal anti-collision bolt unit 2 is connected with the pile fixing bracket 3, the horizontal anti-collision bolt unit 2 at least includes the pile fixing pin 11, which is used to cooperate with the positioning pin hole 6 of the pile leg 4; the laser detection device is used for Detect the position of the pile-fixing pin 11 relative to the positioning pin hole 6. When the pile-fixing pin 11 starts to be inserted, the laser detection device detects that the horizontal position of the pile-fixing pin 11 coincides with the positioning pin hole 6. 11 is inserted into the positioning pin hole 6; when the pile-fixing pin 11 is unloaded, the horiz...

Embodiment 2

[0030] Such as Figure 1 to Figure 3 As shown, the present invention provides an offshore platform pile-fixing pin insertion control system, which includes a pile-fixing bracket 3, pile legs 4, and a lifting system. The lifting system includes a vertical lifting hydraulic cylinder 1 and a lifting plunger 5, and two sets of horizontal The anti-collision latch unit 2, each group of transverse anti-collision latch units includes two oppositely arranged transverse anti-collision latch units, which are respectively the first group of transverse anti-collision latch units and the second group of transverse anti-collision latch units. The pile leg 4 moves up and down in the pile-fixing bracket 3, and the longitudinal lifting hydraulic cylinder is suspended in the pile-fixing bracket 3. The horizontal anti-collision bolt unit 2 is connected with the vertical lifting hydraulic cylinder 1 through the lifting plunger 5, and each vertical lifting hydraulic cylinder 1 drives a horizontal a...

Embodiment 3

[0037] Such as Figure 1 to Figure 3 As shown, the present invention provides a method for controlling the insertion and removal of pile-fixing pins on offshore platforms, which includes the following steps: setting a plurality of positioning pin holes 6 on pile legs 4; when the pile-fixing pins 11 are inserted, the laser detects the The pile fixing pin 11 coincides with the horizontal position of the positioning pin hole 6, and the pile fixing pin 11 is inserted into the positioning pin hole 6; when the pile fixing pin 11 is unloaded, adjust the position of the pile fixing pin 11 When the laser detects that the horizontal position of the pile fixing pin 11 coincides with the positioning pin hole 6, the pile fixing pin 11 is pulled out of the positioning pin hole 6.

Abstract

The invention provides an offshore platform pile fixing pin insertion and extraction control system and a control method thereof. The control system comprises a pile leg provided with positioning pinholes, a pile fixing support and a transverse anti-collision pin insertion unit. The transverse anti-collision pin insertion unit at least comprises pile fixing pins and a laser detection device. The laser detection device is used for detecting positions of the pile fixing pins relative to the positioning pinholes. Through the adjustment on the positions of the pile fixing pins, relative to the pile leg, of the transverse anti-collision pin insertion unit, the transverse anti-collision pin insertion unit inserts the pile fixing pins into the positioning pinholes or pulls the pile fixing pins out of the positioning pinholes when the laser detection device detects that the horizontal positions of the pile fixing pins coincide with the horizontal positions of the positioning pinholes. By employing the system and the method, the friction between the pile fixing pins and the pile leg positioning pinholes during a pile fixing insertion and extraction process is prevented, the collision between the pile fixing pins and the pile leg during a pin insertion process is prevented, and the service lifetimes of the pile fixing pins and the pile leg positioning pinholes are prolonged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an offshore platform pile fixing pin insertion control system and a control method thereof. Background technique [0002] With the aggravation of energy shortage and the increasing shortage of wind farm land resources, offshore wind power generation has become a new direction for the development of wind power generation in the world today. Compared with the installation of onshore wind turbines, the installation of offshore wind turbines is more technically difficult. The manufacture of offshore installation platforms is one of the key technologies for the construction of offshore wind farms. [0003] Pile insertion and pile extraction are the most complicated actions on offshore platforms. Using pin-hole cooperation to realize the rise and fall of pile legs is the most common method of pile extraction and pile insertion. There is clearance fit between the pile fixing pin an...
