Abstract
Provided is a telescopic mast of a drilling machine. The technical problem that an existing telescopic mast is fixed in length, unadjusted, uneconomical and inconvenient to transport and the like is mainly solved. The technical scheme is that the telescopic mast consists of a sliding mast (1), a fixed mast (2), a pulley group (3) and the like. The sliding mast (1) is installed in a sliding groove in the fixed mast (2), and the top end of the sliding mast (1) is provided with the pulley group (3). The telescopic mast is mainly used for the drilling machine and is adjustable in length, convenient to use and transport, low in cost and high in efficiency.
Description
Technical field
The utility model relates to the flexible mast of a kind of drilling machine mast frame for movement, particularly a kind of rig.
Background technology
Rig all needs rapidly and accurately weight shift of mast for realizing the needs of transportation, steady machine, transition etc., changes mast length, thereby is convenient to transportation and the Installation and Debugging of rig.At present, mostly the mast of domestic existing rig is the folding form of employing gyroaxis.Wherein, the length of mast is larger, and the radius of gyration is also larger, and the mast deadweight is also heavier, and when conversion mast state, the rotary space that needs is also larger, and because all need manual operation, labour intensity is larger, and efficient is also low.
Li Liming, the Qiu Jianzhang of Beijing Cortech Drilling Equipment Co., Ltd. are the utility model of a CN201120327882 Telescopic device of drilling machine mast in the application number of declaring 2012.05.09 day recently, comprise: a upper mast of coaxial setting and mast once, the section radius of described upper mast is less than the section radius of described lower mast, and described lower mast inside is provided with and can holds described upper mast retraction cavity wherein; One oil cylinder is arranged on this common axle, in the cavity of described lower mast, and its axial stretching drives that described upper mast stretches out or the cavity of the described lower mast of retraction, and its two ends are separately fixed on described upper mast and the lower mast.It makes the drilling machine mast quick-expansion, and the effect that changes length is really comparatively outstanding.But still there is complex structure in it, inconvenient maintenance, the single deficiency that waits of bore mode.
Summary of the invention
The problems such as the purpose of this utility model provides the flexible mast of a kind of rig, solves existing complex structure, safeguards inconvenience, and cost is higher, and efficient is lower, and bore mode is single.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises slip mast 1, fixed mast 2, assembly pulley 3.Slip mast 1 is installed in the sliding tray in the fixed mast 2, and slip mast 1 top is provided with assembly pulley 3.
The utility model also can be provided with pulley or lubrication oil or other devices at sliding tray and 1 on the slip mast of fixed mast 2.
The utility model also can arrange at the assembly pulley 3 on slip mast 1 top wire rope or chain or other.
The beneficial effects of the utility model are: in the flexible mast that provides, slip mast 1 slides at fixed mast 2, thereby realize the drilling machine mast change in length, satisfy the requirement of rig transition transportation, the debugging of realization Fast Installation, the utility model takes into full account the needs of each state of drilling machine mast, lifting that can be by assembly pulley 3 control masts and falling, finish mast and advance lifting operation, the labour intensity that has alleviated the operator is convenient to again repair and is safeguarded, simultaneously simple and reliable structure design has guaranteed the convenience of safety and the use of product, reduced service working time, made efficient higher
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is working state figure of the present utility model.
Among the figure: 1-slip mast, 2-fixed mast, 3-assembly pulley.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Claims (3)
1. the flexible mast of a rig, it is characterized in that: it comprises: slip mast (1), fixed mast (2), assembly pulley (3), slip mast (1) is installed in the interior sliding tray of fixed mast (2), and slip mast (1) top is provided with assembly pulley (3).
2. according to the flexible mast of claims 1 described rig, it is characterized in that: be provided with pulley or lubrication oil between the sliding tray of fixed mast (2) and slip mast (1).
3. according to the flexible mast of claims 1 described rig, it is characterized in that: the assembly pulley (3) on slip mast (1) top can arrange wire rope or chain.
