Background

In the construction of offshore wind power pile foundations, each drill rod of the independent rock-socketed drilling machine is 4.5 meters high and weighs 6-7 tons, and in the drilling process, a plurality of sections of drill rods need to be assembled to lengthen a drilling tool so as to realize the continuous expansion of the drilling depth. After drilling is finished, the drilling tool needs to be lifted and taken out by disassembling one section of the drilling rod, so that the assembling and disassembling of the drilling rod is an important link with high repetition rate in drilling construction.

In the conventional loading and unloading method, a drill rod to be loaded or unloaded is hoisted to an operation platform by a crane to be placed horizontally, the crane increases the occupied space of the crane, and the direction of the drill rod is mutually converted from horizontal direction to vertical direction, so that time and labor are wasted, and the operation effect is not improved; meanwhile, after the drill rod is transversely placed, the drill rod is easy to roll when encountering wind waves, and risks are increased.

The existing dispatching equipment for the drill rod also has the following defects due to unreasonable structure: 1. the fixing and the separation of each oil cylinder and the tray can not be realized. 2. The drill rod cannot be accurately, conveniently and reliably placed on the tray. 3. The tray is unstable and prone to toppling when moving.

The action process of the invention is as follows: 1. a manipulator of the independent rock-socketed drilling machine takes down a drill rod on a tray of a station to be taken, and the tray is driven to an initial vacant position by a double-rod transverse pulling cylinder (the tray moves one station from front to back). 2. The front side pulling and feeding cylinder pulls a row of trays on the front side rail to move to the positions to be taken (the row of trays moves from right to left by one position). 3. The front side pushing cylinder pushes the tray close to the position of the station to be taken to move to the station to be taken (one tray moves to the left by half from the right). 4. The double-out-rod transverse pull cylinder drives the tray on the right-side track to move forwards (the tray moves one station from back to front). 5.

When the eccentric block moves towards the opposite direction, the eccentric block cannot rotate due to the blocking of the horizontal section of the eccentric block, and the upper inclined plane of the vertical section is higher than the center frame of the tray, so that the tray is hooked. Namely, the piston rod of the front side pushing cylinder, the piston rod of the front side pulling cylinder and the piston rod of the rear side pulling transposition cylinder can hook or loosen the tray.

3. The center of tray upper surface is equipped with initial toper guide post, has played the effect of centering in advance at the manipulator in-process of putting the drilling rod to the tray.

The guide rotating hook further comprises a roller, the roller is connected to the horizontal section of the eccentric stop block, and the roller rolls on the oil cylinder mounting beam. The sliding friction of the eccentric stop block and the oil cylinder mounting beam is changed into rolling friction, so that the abrasion is reduced.
