Description
Technical field
The utility model is related to workover rig field, more particularly, to a kind of well workover self-balancing derrick.
Background technology
In production process, some failures often occur for oil, gas and water well, cause the underproduction of well, or even stop production.In order to tie up
Holding the normal production of well must place under repair to it.Well workover refers to the normal production to recover well or the production energy of raising well
Power, to it release operation and the implementing measure of failure, also known as underground work.The purpose and task of well workover seek to protect
The normal work of well is demonstrate,proved, various underground work are completed, the utilization rate and production efficiency of well are improved, to increase the production of well to greatest extent
Amount.
Domestic main oilfield has been enter into mid-later development phase, and oil gas water well fault rate is continuously increased, light maintenance work operations amount
Increasingly increase, it is necessary to a kind of workover rig rapidly and efficiently, the country is being the structure that leans forward with workover rig derrick at present, leans forward
Angle is generally 3 °~5 °, and the rope system steel wire rope quantity before and after derrick is different, therefore derrick is inevitably born in operation
Tilting moment forward, needs to need pre- digging ground anchor pit before operation, pre-buried earth anchor for this, beats outer guy wire, it is necessary to more cars
Coordinate.Simultaneously with the continuous urbanization in oily area, part oil-water well adjoins living area, and well site land used constantly reduces, and this also leads
Conventional well workover machine operation has been caused to have received increasing restriction.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provide a kind of well workover self-balancing derrick.
The new technical scheme of the utility model is：A kind of well workover self-balancing derrick, including steel wire, derrick, day kickstand, after
Assembly pulley, front wheel group, combination hook-block, fixed pulley group, dead line end, described derrick are vertically mounted on base or vehicle-mounted chassis, its
There is overhead traveling crane derrick upper end, and overhead traveling crane is made up of day kickstand, front wheel group, rear wheel group, described front wheel group, rear wheel group position
In the two ends of day kickstand, wherein front wheel group is located at side, rear wheel group and steel wire rope, fixed pulley group, dead line end with combination hook-block
Positioned at side；Described steel wire rope is reached the fast line in front wheel group by winch drum by the fast line wheel in rear wheel group first
Wheel, the dead line sheave in front wheel group is reached after combination hook-block and combination hook-block pulley, the dead line sheave in rear wheel group is then back to, rear sliding
Dead line sheave, transition pulley and fixed pulley group and dead line end composition dead line train balance weight on hook in wheel group.
Described front wheel group forms advancing slip train with combination hook-block, and rear wheel group forms rear wheel with fixed pulley group, dead line end
System, front and rear pulley system is formed for same Wirerope reeving.
The rope number of pulley system is equal before and after described derrick.
The beneficial effects of the utility model are：The utility model provides a kind of self-balancing derrick without tilting moment, can be with
Workover treatment is completed under conditions of without outer guy wire, operating efficiency is improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is derrick wire rope handling figure of the present utility model.
Wherein：1 it is steel wire rope, 2 be derrick, 3 be a day kickstand, 4 be rear wheel group, 5 be front wheel group, 6 is combination hook-block, 7
For fixed pulley group, 8 be dead line end, 9 be fast rope sheave, 10 be transition pulley, 11 be dead line sheave, 12 be dead line sheave, 13 be combination hook-block slide
