Description
Technical field
This utility model belongs to technical field of petroleum machinery, is related to a kind of telescope pole raising auxiliary device.
Background technology
For telescope pole, the structure of jack up unit often determines the space layout of derrick, and a kind of good derrick rises
Rising device can not only optimize the structure of telescopic derrick, and can improve rig and carry out the effect of derrick lifting during lower a bite well operations
Rate, reduces the non-drilling activity duration.
At present jack up unit mostly is tripod form during routine telescope pole raising, monolateral to adopt steel cable, though
So the structure of tripod form is firm, but during for the telescopic derrick raising for being provided with top drive, it is impossible to directly using top drive apparatus
Derrick lifting is completed, is susceptible to swim the collision of crane system and overhead traveling crane；And the device does not have interchangeability, for different manufacturers
Trip hang equipment and may cause that derrick geometry and jack up unit need to be redesigned；In addition, top need to be removed in derrick telescoping driving, weight
It is new that trip crane system and raising tripod are installed, so not only install complicated, derrick lifting efficiency is reduced, cause the non-drilling time
Increase.
Utility model content
The purpose of this utility model is to provide a kind of telescope pole raising auxiliary device, solves prior art raising dress
Put and do not have versatility, install complicated, derrick lifting efficiency is low, cause the problem that the non-drilling time increases.
The technical scheme that this utility model is adopted is, a kind of telescope pole raising auxiliary device, including mounting bracket,
Mounting bracket upper surface is welded with drilling rod upper connection；Two groups of power blocks are installed mounting bracket internal cavities are parallel, two
Group power block is supported and fixed on the side wall of mounting bracket together by bearing pin；
Supporting, in bottom, upper derrick or so inner side is respectively arranged with an otic placode, in top derrick lower end left and right sides
A leading block is respectively arranged with, the steel wire rope from the otic placode extraction of bottom derrick left side is up around in two groups of power blocks
One power block, bypasses still further below the leading block on right side, then slides up around another power in two groups of power blocks
Wheel, bypasses still further below the leading block in left side, then takes back left side otic placode, constitutes a closed-loop path.
Telescope pole raising auxiliary device of the present utility model, is further characterized in that：
The two ends of bearing pin are mounted on lubricating cup and clamp.
The beneficial effects of the utility model are the versatility of suspension ring, elevator and tool joint to be driven using top, by elevator
With the direct locking of tool joint, realize that providing power by top drive on the premise of top drive and suspension ring are not removed is rapidly completed derrick
Raising and decentralization work；Meanwhile, the jack up unit adopts two groups of pulley structures, hoist rope one end elder generation and hoist rope ear
Plate connects, and the corresponding power block in jack up unit is bypassed through the leading block on derrick, with good power transitivity,
Derrick lifting required drive can to a certain extent be reduced；The jack up unit generally symmetrical structure, the raising of derrick both sides
Steel wire rope one end can symmetrically be connected to jack up unit, with preferable stability.

Specific embodiment
This utility model is described in detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1, Fig. 2, structure of the present utility model is, including mounting bracket 3, and the upper surface of mounting bracket 3 is welded with brill
Bar upper connection 1；Two groups of power blocks 2 are installed the internal cavities of mounting bracket 3 are parallel, two groups of power blocks 2 pass through together
Bearing pin 4 is supported and fixed on the side wall of mounting bracket 3, and at the two ends of bearing pin 4 lubricating cup 5 and clamp 6 are mounted on, and is easy to whole dress
Putting carries out the dismounting and maintenance in later stage.
Supporting with reference to Fig. 3, in bottom, upper derrick or so inner side is respectively arranged with an otic placode, under the derrick of top
End left and right sides is respectively arranged with a leading block 9, and the steel wire rope 8 drawn from bottom derrick left side otic placode is dynamic up around two groups
A power block in power pulley 2, bypasses still further below the leading block 9 on right side, then up around in two groups of power blocks 2
Another power block, bypasses still further below the leading block 9 in left side, then takes back left side otic placode, constitutes a closed-loop path.
With reference to Fig. 3, occupation mode of the present utility model is,
When rig is when completing a bite well drillng operation and needing removal of home, using jack up unit of the present utility model, can be without
Remove top and drive 7 and its auxiliary device (suspension ring, elevator).When rig movement is to lower mouth well, during derrick telescoping, by steel wire rope 8 one
End is connected with the otic placode of bottom upper derrick, and steel wire rope 8 is passed through into the leading block 9 of top derrick lower end, and bypasses this practicality
Two groups of power blocks 2 in new jack up unit.During derrick telescoping, drilling rod upper connection 1 drives 7 tool joints pair with top upwards
Connect, top is driven 7 and drives mounting bracket 3 to rise by drilling rod upper connection 1, it is raising of the present utility model dress that top drives 7 by winch
Offer power is put, this plays transmission of the lift by two groups of power blocks 2, make steel wire rope 8 that there is enough power by top derrick
Directly lift from below, the locking point of retaining mechanism and bottom derrick near upper end is passed through after top derrick reaches desired height
Locking, it is fixed.See Fig. 3, the position that top derrick is lifted, otic placode of the leading block 9 upwards near bottom derrick is attached
Closely, i.e., top derrick has arrived at the highest order of rising.
