Abstract
An electric workover rig without guy ropes comprises a load car chassis, a working derrick, an electric control cabinet, and an electric drive winch, wherein the working derrick, the electric control cabinet, and the electric drive winch are installed on the load car chassis. The working derrick further comprises a front support frame on the front portion of the load car chassis, a rear support frame on the rear portion of the load car chassis, and a lifting oil cylinder arranged between the front support frame and the rear support frame. The front portion of the working derrick is movably connected with the front support frame, and the rear portion of the working derrick is hinged with the rear support frame. One end of the lifting cylinder is fixed on the load car chassis, and the other end of the lifting cylinder is connected with the working derrick. The electric workover rig without the guy ropes has the advantages of being fast in lifting speed, short in installation time, high in working efficiency, and convenient to move. Compared with the prior art, the electric workover rig without the guy ropes has the advantages that control is easy, performance is reliable, motive power cost is greatly reduced with net electricity as a motive power source, the external guy ropes are not needed when the electric workover rig works, work preparation time is reduced, and working efficiency is improved.
Description
Technical field
The utility model belongs to the petroleum well servicing rig field, specifically a kind of no guy wire electric workover rig.
Background technology
In every construction of petroleum natural gas exploration, workover treatment is an important step.The oil gas well can break down in blowing, oil pumping or water filling gas injection process at any time, causes the oil well underproduction even stopping production.After breaking down, have only by underground work and fix a breakdown, change underground equipment, adjust oilwell parameter, recover the ordinary production of oil well.The exploitation of present domestic main oilfield all enters the middle and later periods, the demand that underload, simple work operations amount increase.Such job execution promotes low, the activity duration weak point of loading, the implement that movement is convenient, installation rate is fast, operating speed is fast.
The workover rig of present domestic use is Diesel Driven, and the stability when guaranteeing the workover rig operation needs earth anchor is installed, and connects outer guy wire, causes operation to prepare big leap ahead, can't satisfy the requirement that has operation now.Therefore developing a kind of present workover treatment equipment of guy wire electric workover rig replacement that do not have, improve operating efficiency, is very necessary.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of no guy wire electric workover rig to replace traditional workover rig, solving present workover rig the defective that positioning time is long, operating efficiency is low is installed.
Its technical scheme is: comprise that the workover derrick, electrical control cubicles and the electricity that carry chassis and go up installation drive winch, described operation part also comprises the lift oil tank that arranges between the fore-stock that carries the chassis front portion, the after-poppet that carries the chassis rear portion and the front and back support; Described workover derrick is anterior to be hinged on the after-poppet with fore-stock flexible connection, rear portion, and an end of described lift oil tank is fixed on year chassis, the other end is connected with workover derrick.
Such scheme can further be improved to
The chassis rear portion was provided with H type telescopic outrigger in described year, rear support leg withdrawal in the movement process, and supporting leg stretches out in the workover treatment process, can overcome rollover moment.
Described workover derrick is single-stage derrick or twin-stage derrick, and crown is provided with overhead traveling crane.
Described H type telescopic outrigger is by hydraulic pressure or manually control is flexible.
The utlity model has that hoisting velocity is fast, set-up time weak point, operation timeliness height, the characteristics easily of migrating, compared with prior art, the beneficial effects of the utility model are:
1, simple, the dependable performance of control.
2, adopt net electrical actuation power source, make power cost reduce greatly.
3, need not outer guy wire during operation, shorten operation time, improved the operation timeliness.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
The state diagram of H type telescopic outrigger when Fig. 3 is operation;
Among the figure, 1, overhead traveling crane, 2, workover derrick, 3, carry chassis, 4, fore-stock, 5, electrical control cubicles, 6, electricity drives winch, 7, lift oil tank, 8, H type telescopic outrigger, 9, operating room, 10, after-poppet, 11, Hydraulic Station.
The specific embodiment
Below come further the utility model to be described by specific embodiments and the drawings.
With reference to Fig. 1-3, a kind of no guy wire electric workover rig, comprise that the workover derrick 2, electrical control cubicles 5 and the electricity that carry chassis 3 and upward install that traditional workover rig is provided with drive winch 6, also comprise the lift oil tank 7 that arranges between the fore-stock 4 that carries chassis 3 front portions, the after-poppet 10 that carries chassis 3 rear portions and the front and back support; Workover derrick 2 front portions flexibly connect with fore-stock 4, the rear portion is hinged on the after-poppet 10 and can and supports the location around its rotation, and an end of lift oil tank 7 is fixed on year chassis 3, the other end is connected with workover derrick 2.Carry chassis 3 rear portions and also be provided with by hydraulic pressure or the flexible H type telescopic outrigger 8 of manual control, rear support leg withdrawal in the movement process, supporting leg stretches out in the workover treatment process, can overcome rollover moment.Workover derrick 2 is single-stage derrick or twin-stage derrick, and crown is provided with overhead traveling crane 1.
During movement, with a side of workover derrick 2 bottoms and the dismounting that is connected of after-poppet 10, pack up lift oil tank 7, the time workover derrick 2 around the hinge point rotation of its bottom opposite side and after-poppet 10, recline also fastening until the nearly level of workover derrick 2 main bodys and fore-stock 4.Otherwise, during operation, gets final product according to opposite step, and before operation, H type telescopic outrigger 8 is stretched out, and the branch supporting leg of both sides is firm with ground supports respectively.
