Utility model content
The purpose of this utility model is to provide a kind of ocean exploration ship hydraulic lifting door type derrick well system, solves existing
Have that the ocean exploration ship rig of technology is unreasonable in structure setting, the volume that takes up room is big, weight weight, integration degree be not high
This utility model be employed technical scheme comprise that, a kind of ocean exploration ship hydraulic lifting door type derrick well system,
In the postmedian of ocean exploration ship, derrick is installed, in derrick inside casing along being provided with slide rail, is provided with top in slide rail and drives, in derrick
The every side in top is mounted on two fixed pulleys, is separately installed with one group of basal disc stretcher outside upper derrick two；After derrick
Facade is hinged with elevating ram, and elevating ram cylinder body lower end is hinged with the ear mount on deck；The deck of derrick both sides is installed
There is basal disc winch；
The basal disc steel wire rope that basal disc winch from every side is drawn bypasses the basal disc stretcher of this side and two fixed pulleys successively
It is connected with the seabed basal disc in investigation vessel moon pool afterwards；After the boom hoist cable that dead line anchor is drawn bypasses the guide wheel of this side successively with
Top is driven and is connected.
Ocean exploration ship hydraulic lifting door type derrick well system of the present utility model, is further characterized in that:
Dead line anchor, dynamic catwalk and grab pipe machine are respectively arranged with the deck in front of derrick, the bottom of derrick both sides is respectively
Liquid gas tong is installed, derrick is provided with video monitor.
Derrick is supporting to be provided with driller house, and the controlling organization in driller house is connected with the control of each action component.
The beneficial effects of the utility model are, including the following aspects:
1) elevating ram of door type derrick configuration instead of the supporting well drilling hoist of conventional derrick and overhead traveling crane, using hydraulic oil
Cylinder and sliding system match and drive top to drive up and down motion, realize the put-on and delegated function of drill string；Door type derrick and routine simultaneously
It is obvious that derrick compares weight reduction effect.
2) supporting hydraulic power supply provides power for the equipment such as most of drilling equipment and passive compensation system, thus dropping
Low number of devices, reduces the overall dimensions of equipment.
3) door type derrick structure is simple, is more suitable for the well-sampling operation of shallow water area, disclosure satisfy that surveying of 500 meters of depth of waters
Examine and sampling demand it is not necessary to supporting conventional derrick need overhead traveling crane, the equipment such as winch.Meanwhile, the lift cylinder of door type derrick
There is lifting/decentralization, passive compensation function, without passive compensator being separately configured it is only necessary to configure Hydraulic Station, thus reducing
Number of devices, reduces the overall dimensions of equipment, and whole system is few for quantity, and electrical equipment quantity is low, safeguards and use cost
It is greatly lowered, improve working performance.

With reference to the accompanying drawings and detailed description this utility model is described in detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, structure of the present utility model is to be provided with derrick 2 in the postmedian of ocean exploration ship,
Derrick 2 comprises the parts such as bearing, lift rail, guide wheel；In derrick 2 inside casing along being provided with slide rail 9, in slide rail 9, it is provided with top drive 3
(containing elevator), is mounted on two fixed pulleys 1 in the every side in derrick 2 top, is separately installed with one group of base outside derrick 2 top two
Disk stretcher 13；After derrick 2, facade is hinged with elevating ram 5, and elevating ram 5 cylinder body lower end is hinged with the ear mount on deck；
On the deck in derrick 2 front, it is respectively arranged with dead line anchor 8, dynamic catwalk 15 and grab pipe machine 14, grab pipe machine 14 is located at power cat
The side of road 15 longitudinal direction, is separately installed with liquid gas tong 7 in the bottom of derrick 2 both sides, is provided with the deck of derrick 2 both sides
Basal disc winch 11；
The basal disc steel wire rope 16 that basal disc winch 11 from every side is drawn bypasses the basal disc stretcher 13 of this side and two successively
Be connected with the seabed basal disc 12 in investigation vessel moon pool after fixed pulley 1, realize seabed basal disc 12 on put and put and transfer steel wire rope
Tensioning；Drive 3 with top after the boom hoist cable 4 that dead line anchor 8 is drawn bypasses the guide wheel of this side successively to be connected, realize the upper of drilling rod
Refer to decentralization.In the suitable level locations of derrick 2, video monitor 6 is installed, supporting near derrick 2 is provided with driller house
10, the controlling organization in driller house 10 is connected with each action component aforesaid control.
Work process of the present utility model is,
Derrick 2 is put in place by elevating ram 5 raising after being completed, and the steel wire rope of basal disc winch 11 is through basal disc stretcher
13 and the fixed pulley 1 at derrick 2 top seabed basal disc 12 is put in investigation vessel moon pool.Drilling rod is put into dynamic catwalk by grab pipe machine 14
15, drilling rod one end is lifted and is delivered to pithead position by dynamic catwalk 15.Now boom hoist cable 4 one end is fixed on dead line anchor 8, and one
End is driven 3 by the guide wheel of derrick 2 and top and is connected.Top drives 3 under boom hoist cable 4 effect, is fallen by the slide rail 9 on derrick 2
To above well head, its elevator apparatus is caught drilling rod and drilling rod is risen to certain altitude, makees in the erection device of dynamic catwalk 15
With under, drilling rod is transferred to rotating disk well head and fixing.Now, 3 recompounding are driven on grab pipe machine 14, dynamic catwalk 15 and top, will
Second drilling rod is lifted and transfers and be connected with first drilling rod, and the liquid gas tong 7 being equipped with by derrick 2 completes to connect thribble operation.
Finally, along 9 times brills of slide rail of derrick 2, drilling rod end is transferred to sea through investigation vessel moon pool with seabed basal disc 12 for top drive 3
Bottom, starts operation.
