Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1-6 As shown, a pile frame jacking device of a piling ship includes a slideway 2 arranged on the pile frame 1, one end of the slideway 2 is arranged at the junction of the rear side bar 3 and the lower side bar 4 of the pile frame 1, and the sliding The other end of the road 2 is arranged near the piling surface of the pile frame 1. When the pile frame 1 stands up, the end of the slideway 2 close to the piling surface of the pile frame 1 is higher than the other end; the slideway 2 is provided with a movable block 5; A main oil cylinder 6 is hinged, and the main oil cylinder 6 is a double-acting oil cylinder. The end of the piston rod of the main oil cylinder 6 is hinged with the movable block 5. One end of the slideway 2 at the piling surface is provided with an upper fixed point 21 for fixing the movable block 5, and the...

Abstract

The invention discloses a pile frame jacking device of a pile driving barge, and a related pile frame jacking and lying method. The pile frame jacking device comprises a slideway arranged on a pile frame; one end of the slideway is arranged at the joint of a rear side rod and a lower side rod of the pile frame, and the other end of the slideway is arranged at the position close to a pile driving surface of the pile frame; one end, close to the pile driving surface of the pile frame, of the slideway is higher than the other end of the slideway when the pile frame is erected; a movable block isarranged in the slideway; a main oil cylinder is hinged to a barge body; the end part of a piston rod of the main oil cylinder is hinged to the movable block; an upper fixing point for fixing the movable block is arranged at one end, positioned at the pile driving surface, of the slideway; a lower fixing point for fixing the movable block is arranged at the other end of the slideway; when the movable block on the pile frame is fixed to the lower fixing point, the piston rod of the main oil cylinder stretches out to enable the pile frame to be in an upright state; two auxiliary pushing oil cylinders for assisting in pushing the pile frame at the front half section of the pile frame erecting process and then are separated from the pile frame are hinged to the barge body in parallel; and theincluded angle between the pile frame and a vertical plane is less than 45 degrees when piston rods of the auxiliary pushing oil cylinders extend out completely.

Description

technical field [0001] The invention relates to a piling ship, in particular to a pile frame jacking device of the piling ship and a method for jacking up and laying down the pile frame. Background technique [0002] At present, the pile frame of the piling ship is lifted and lowered from the rest frame of the pile frame, and the main oil cylinder is generally used to change the twist jacking method twice. However, when the pile frame is initially lifted, the position of the main oil cylinder for jacking the pile frame is not good. The moment arm is very small, so the main cylinder must have a large jacking force to lift the pile frame from the rest frame or drop it to the rest frame. The main cylinder pushes the pile frame at a single point, and the local load of the pile frame is large. The jacking force required by the oil cylinder is much greater than that required for the piling operation of the piling barge. Contents of the invention [0003] The technical problem t...
