Abstract
The invention relates to a stretchable mast for a drilling machine, which mainly solves the technical problems that current mast of the drilling machine is fixed in length which cannot be adjusted so that the mast of the drilling machine is not economical and inconvenient to carry and the like. The key point of the technical scheme is that the stretchable mast for the drilling machine consists of a sliding mast (1), a fixed mast (2) and a pulley block (3) and the like. The sliding mast (1) is installed in a sliding groove in the fixed mast (2), and the pulley block (3) is arranged at the top end of the sliding mast (1). The invention mainly provides the stretchable mast for the drilling machine which is adjustable in length, convenient to use and carry, low in cost, and high in efficiency.
Description
Technical field
The present invention 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 purpose of this invention is to provide the flexible mast of a kind of rig, solve existing complex structure, safeguard inconvenience, the problem such as cost is higher, and efficient is lower, and bore mode is single.
The technical solution adopted for the present invention to solve the technical problems 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 present invention 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 present invention also can arrange at the assembly pulley 3 on slip mast 1 top wire rope or chain or other.
The invention has the beneficial effects as follows: 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 present invention 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 invention.
Fig. 2 is working state figure of the present invention.
Among the figure: 1-slip mast, 2-fixed mast, 3-assembly pulley.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further details.
Embodiment 1, and the present invention is comprised of slip mast 1, fixed mast 2, assembly pulley 3 etc.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 bore operation that applicable different lengths requires.Consult Fig. 1-Fig. 2.
Embodiment 2, and 1 on the sliding tray of fixed mast 2 and slip mast are provided with pulley or lubrication oil or other devices, can reduce resistance, better move up and down, raise the efficiency, and Fig. 1-Fig. 2, all the other are with embodiment 1.
Embodiment 3, and the assembly pulley 3 on slip mast 1 top can arrange wire rope or chain or other and fall or promote the slip mast, finishes the propelling enhancing action of mast, Fig. 1-Fig. 2, and all the other are with above-mentioned embodiment.
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 or other devices 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 or other.
