Abstract
The utility model provides a drill winch capable of being lifted by a helicopter. The drill winch comprises a mounting base, two alternating-current variable-frequency motors, two speed-changing gear boxes, and a single drum shaft, wherein the alternating-current variable-frequency motors is connected with the speed-changing gear boxes by a ball cage type synchronous universal shaft coupler; the speed-changing gear boxes are respectively connected with the two ends of the single drum shaft by the ball cage type synchronous universal shaft coupler; and the mounting base is provided with locating blocks adapted with the alternating-current variable-frequency motors, two speed-changing gear boxes and the single drum shaft. The winch structure is subjected to scientific and reasonable modularization design for strictly controlling the weight of each of lifting unit modules to be within the specified range, so that the weight requirements of helicopter lifting units can be satisfied, and quick field mounting can be realized to meet the normal drilling operation.
Description
Technical field
the utility model belongs to technical field of petroleum extraction; Relate to a kind of petroleum drilling and mining lifting means; Relate in particular to a kind of boring winch that supplies the helicopter lifting, be mainly used in as installing and using under the specific environments such as virgin forest, innerland, desert, marsh beach.
Background technology
winch is as the core component of rig, and its performance indicators the quality of rig performance.Land and marine communication means are all adopted in existing land and the transportation of marine rig winch; Installation for ease of the scene; Structure design generally all adopts one-piece construction; General split also is no more than three bulks for especially big overweight ultra wide split winch, and every weight all do not have the strict restriction requirement, but is containing virgin forest, innerland, desert, the marsh beach that enriches oil resources for those; Can't rig be transported to the destination with the land transport vehicle, have only the helicopter of employing to carry out handling.And the weight that helicopter transports hanging unit has strict upper limit control, because weight issue, if winch structure adopts unit design can't realize the helicopter handling.
The utility model content
The purpose of
the utility model provides a kind of boring winch that supplies the helicopter lifting.
the utility model can supply the boring winch of helicopter lifting; Comprise mounting seat and about two ac variable-frequency electric motors, about two speed-changing gear boxs and a single drum shaft, said left and right sides ac variable-frequency electric motor connects through synchro-nizing universal coupling with ball and sacker with the left and right tooth wheel-speed regulating change box; Said left and right tooth wheel-speed regulating change box connects through synchro-nizing universal coupling with ball and sacker with the two ends of single drum shaft respectively.Said mounting seat is provided with and said left and right sides ac variable-frequency electric motor, left and right tooth wheel-speed regulating change box, the suitable locating piece of single drum shaft.Said locating piece is a wedge locating block.
The cylinder two ends of
said single drum shaft are provided with assist brake, and this assist brake adopts hydraulic disc brake.Main brake adopts the alternating-current variable frequency motor resistance braking.
The principle of work of
the utility model: the ac variable-frequency electric motor by two high speeds, wideband, high pulling torque provides active force; Respectively through direct drive list drum shaft after the single speed speed-changing gear box speed change, adopt the AC frequency conversion vector control technology to control main motor and realize the rising of rig, drilling operation and automatic bit feed function such as drilling tool down.
The relative prior art of the utility model has the following advantages:
(1) the utility model carries out scientific and reasonable modular design to winch structure; Each lifting elements module weight is strict controlled within the specialized range; Can not only satisfy the weight requirement of helicopter trolley units; And can also realize on-the-spot Fast Installation, satisfy normal well-digging operation.
(2) the utility model transports number of times, reduces traffic cost, is convenient to on-site installation with minimizing in design is that general principle carries out split to winch; Winch is divided into 5 modules; Adopt the high strength bolt nut to connect between piece and the piece closing; And join locating piece or locating dowel pin is located, guaranteed the reliability and stability of on-the-spot Fast Installation.
Synchro-nizing universal coupling with ball and sacker has all been adopted in being connected between
(3) roller device and electric machine and the left and right gear case.Ball cage universal coupling can be completely achieved the constant speed transmission; Can suppress effectively because vibration and the impact that the variation of motor speed and torque produces the gear case that links; And can compensate the two between centers relative displacement errors that connect mutually, and have mounting or dismounting conveniently, safeguard simple; Low cost and other advantages can realize the Fast Installation and the dismounting of field module.
Description of drawings
Fig. 1 is the fundamental diagram of the utility model;
Fig. 2 is a winch partitioned organization scheme drawing.
The specific embodiment
further specify below in conjunction with the transmission principle and the branch body structure of accompanying drawing to the utility model winch.
are with reference to Fig. 1; A kind of boring winch that supplies the helicopter lifting; Comprise mounting seat 2, about the ac variable-frequency electric motor 4,5 of two high speeds, wideband, high pulling torque, left gear change speed gear box 1; Right gear change speed gear box 8 and single drum shaft 3 be totally five lifting modules, and each lifting module weight all is controlled in nine tons.Wherein left and right sides ac variable-frequency electric motor 4,5 connects through synchro-nizing universal coupling with ball and sacker 6 with left and right speed-changing gear box 1,8 respectively; Left and right tooth wheel-speed regulating change box 1,8 connects through synchro-nizing universal coupling with ball and sacker 6 with the two ends of single drum shaft 3 respectively.Main brake is by the alternating-current variable frequency motor resistance braking.Be provided with assist brake 7 at the two ends of single drum shaft 3, this assist brake adopts hydraulic disc brake.Mounting seat 2 is provided with and left and right sides ac variable-frequency electric motor 4,5; Left gear change speed gear box 1, right gear change speed gear box 8, left gear change speed gear box wedge locating block 10, right gear change speed gear box wedge locating block 11, single drum shaft wedge locating block 12 that single drum shaft 3 is suitable.
When installed
