Pile holding system of underwater pile foundation construction platform

Abstract

The invention discloses a pile holding system of an underwater pile foundation construction platform, and relates to parts of a pile driver. The pile holding system of the underwater pile foundation construction platform comprises a mounting frame, a guide frame and a clamping anti-collision mechanism, the guide frame is connected to the upper end of the mounting frame, the guide frame is connected with an imaging sonar and a laser transmitter, the clamping anti-collision mechanism comprises a plurality of connecting rod assemblies, each connecting rod assembly comprises a triangular connecting rod, a connecting rod, a roller, a hydraulic cylinder and an anti-collision plate, one corner of each triangular connecting rod is hinged to the mounting frame, the corner, close to a foundation pile, of each triangular connecting rod is connected with the corresponding roller, the corner, away from the foundation pile, of each triangular connecting rod is hinged to a piston rod of the corresponding hydraulic cylinder, a cylinder barrel of each hydraulic cylinder is hinged to the mounting frame, the anti-collision plates are arranged above the rollers and between the hydraulic cylinders andthe foundation pile, one ends of the anti-collision plates are hinged to the mounting frame, the other ends of the anti-collision plates are hinged to the connecting rods, and the other ends of the connecting rods are hinged to the triangular connecting rods. The pile holding system can adapt to different foundation pile diameters, the foundation pile can be placed into the pile holding system ata time, the perpendicularity of the foundation pile is guaranteed, and the service life of the pile holding system is long.

Description

technical field [0001] The invention relates to components of a pile driver, in particular to equipment for positioning and guiding foundation piles. Background technique [0002] The main problems of existing pile holding systems for underwater pile foundation construction platforms are as follows: (1) Only single-diameter foundation piles can be constructed. When constructing foundation piles with different diameters, the corresponding diameter must be replaced. For the pile-holding system, the replacement process is very complicated and time-consuming, resulting in a great waste of manpower and resources; (2) There is no position indicating device for the pile-holding system, because the underwater pile foundation construction platform is located tens of meters below sea level On the seabed, there is no position indicating device for the pile holding system. When the foundation piles are lowered into the pile holding system through the pile hanging system, it is difficult...

[0002] The main problems of existing pile holding systems for underwater pile foundation construction platforms are as follows: (1) Only single-diameter foundation piles can be constructed. When constructing foundation piles with different diameters, the corresponding diameter must be replaced. For the pile-holding system, the replacement process is very complicated and time-consuming, resulting in a great waste of manpower and resources; (2) There is no position indicating device for the pile-holding system, because the underwater pile foundation construction platform is located tens of meters below sea level On the seabed, there is no position indicating device for the pile holding system. When the foundation piles are lowered into the pile holding system through the pile hanging system, it is difficult to put the foundation piles into the pile holding device at one time. It must be adjusted many times, which takes a long time. Causes a waste of manpower and resources; (3) There is no protection device for the pile-holding system, and it is easy to cause impact damage to the mechanical structure of the pile-holding system when the foundation pile is lowered to the pile-holding system through the pile-hanging system; (4) The foundation pile cannot be constructed when its verticality compared to the horizontal plane is adjusted
