Background technology
In the wellbore construction operation process, drilling rod butt joint is important comb operation wherein, and each comb quantity is 3, needs butt joint 2 times.At present, generally adopt single station rat hole to finish the butt joint of drilling rod, after finishing butt joint for the first time, the drilling rod that butt joint need be finished takes out, and temporarily places on other equipment, and then put into 1 drilling rod in single station hydraulic pressure rat hole, the drilling rod that has connected is fetched, finished butt joint.In docking operation, the drilling rod centralizer is to keep the upright device of drilling rod, avoids being difficult in the process of stacks the appearance of centering phenomenon.This device, production efficiency is low, because a comb station only is provided, so must after butt joint finishes for the first time, drilling rod be taken out, vacate station and carry out next operation, need to set interim storing unit, and increase handling process, in addition, the drilling rod centralizer is positioned on the offshore boring island plane in the former scheme, must dismantle when cat road machine need be crossed it.
The utility model content
Technical problem to be solved in the utility model is to solve to utilize single station rat hole to finish the low problem of drilling rod butt joint production efficiency.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of multistation rat hole device, comprise top supporting frame, at least two rat hole bodies and with rat hole body drilling rod centralizer, lifting hydraulic cylinder, drilling rod buffer and the lifting pulley group of corresponding one by one configuration respectively, described top supporting frame is used for fixing on offshore boring island; Described rat hole body is arranged side by side respectively below top supporting frame and with it fixedlys connected, and has the through hole that leads to the rat hole intracoelomic cavity on the described top supporting frame, and this through hole is used for interspersed drilling rod; Described drilling rod centralizer is separately fixed on the top supporting frame and central axis overlaps with the central axis of rat hole body; Its underpart of described lifting hydraulic cylinder is fixed on respectively on the outer wall of rat hole body bottom; Described drilling rod buffer is slidingly arranged in respectively in the inner chamber of rat hole body; Fixed pulley group in the described lifting pulley group is fixed on respectively on the outer wall on rat hole body top, running block is connected with the top of lifting hydraulic cylinder respectively, wire rope one end in the lifting pulley group is fixed, the other end is walked around fixed pulley group and movable pulley and drilling rod buffer respectively and is fixed, and the flexible drive drilling rod buffer of lifting hydraulic cylinder is done elevating movement in the opposite direction.
In the such scheme, this multistation rat hole device is provided with two rat hole bodies.
Be provided with two fixed pulleys and two movable pulley in the described lifting pulley group.
The utility model has adopted multistation rat hole apparatus structure, and at least two comb stations are provided, and can simultaneously two single tubes be arranged in the rat hole, and after the 3rd single tube connects, can directly be connected with the single tube that is left, and enhances productivity greatly.Simultaneously, original independent drilling rod centralizer is arranged in the rat hole, makes the drilling rod centralizer be positioned at the below on offshore boring island plane, drive when needing cat road machine to carry single drilling rod when the top, can directly cross rat hole, made things convenient for time single work flow, save the space, make things convenient for other equipment operations.
Description of drawings
Fig. 1 is the structural representation of the utility model multistation rat hole device;
Fig. 2 is the lateral view of multistation rat hole device among Fig. 1;
Fig. 3 is the drilling rod buffer enlarged drawing of the utility model multistation rat hole device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises top supporting frame 1, two rat hole bodies 4,5 and with rat hole body 4,5 drilling rod centralizer 2, lifting hydraulic cylinder 6, drilling rod buffer 7 and the lifting pulley group 3 of corresponding one by one configuration respectively, described top supporting frame 1 is used for fixing on offshore boring island; Described rat hole body 4,5 be arranged side by side respectively below top supporting frame 1 and with its bolt, have two through holes that lead to rat hole body 4,5 inner chambers on the top supporting frame 1, this through hole is used for interting drilling rod; Described drilling rod centralizer 2 lays respectively at the below of top supporting frame 1, and central axis fixing with top supporting frame 1 overlaps with the central axis of rat hole body 4,5 respectively; The cylinder body of described lifting hydraulic cylinder 6 is separately fixed on the outer wall of rat hole body 4,5 bottoms, and piston rod upwards is slidingly arranged in respectively on the outer wall of rat hole body 4,5; Described drilling rod buffer 7 is slidingly arranged in respectively in the inner chamber of rat hole body 4,5; Be provided with two fixed pulleys and two movable pulley in the described lifting pulley group 3, wherein fixed pulley is separately fixed on the outer wall on rat hole body 4,5 tops, movable pulley is connected with the piston rod of lifting hydraulic cylinder respectively, wire rope one end in the lifting pulley group 2 is fixed, and it is fixing that the other end is walked around two fixed pulleys and two movable pulley and drilling rod buffer 7 respectively.
