Abstract
A mast of a rotary drilling rig comprises a mast body and guide rails mounted on the two sides of the mast body, and is characterized in that the mast body includes three steel plates, and the cross section of the mast body is triangular; and the guide rails formed by bending a whole steel plate are mounted on the two sides of the mast body. The utility model has the advantages of simple manufacturing, low manufacturing cost, as well as easy, convenient and speedy operation; the triangular mast not only saves materials, but also is light in weight, so that a large amount of energy can be saved during the mast rising and falling; and the guide rails formed by bending the whole steel plate can be conveniently and accurately fixed on the same horizontal plane for higher welding efficiency, so that the working efficiency and quality can be greatly improved.
Description
Technical field
The utility model relates to a kind of rotary drilling rig mast.
Background technology
Rotary drilling rig mast commonly used at present is made up of mast body and the guide rail that is welded on the mast body both sides, the cross section of mast body mostly is square, mast body need consume more material when welding like this, and weight is big, in the process of rising and falling of mast, consume the more energy, and tetragonal mast body less stable, guide rail is at first distinguished the postpone of relative mast body corrective positioning when welding, weld again, the required precision height of welding, otherwise two guide rails influence the operate as normal of mast not on same horizontal plane.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and reduce the material that the welding mast body needs, and reduce mast body weight, rotary drilling rig mast simply and easily during the guide rail welding.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary drilling rig mast, comprise mast body and the guide rail that is installed in the mast body both sides, it is characterized in that: described mast body is made up of three block plates, its cross section is a triangle, described guide rail is that a monoblock steel plate curves, and is installed in the both sides of mast body.
Guide rail is that a formation of lots square steel curves, and is simple to operate, and can buy easily from the market.
By the triangle mast body that three block plates are welded into, in light weight, Stability Analysis of Structures, the guide rail of mast body both sides is that a monoblock steel plate curves, and can easily guide rail be fixed on the same horizontal plane.
The beneficial effect that the utility model had is: make simple, cost is low, simple, convenient when practical operation, quick, the triangle mast is not only saved material, and in light weight, can save a large amount of energy in the process of rising and falling of mast, the guide rail that curves by a monoblock steel plate, can make things convenient for to be fixed on accurately on the same horizontal plane, efficient is higher during welding, increases work efficiency greatly and work quality.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, mast body; 2, guide rail;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1: a kind of rotary drilling rig mast, comprise mast body 1 and the guide rail 2 that is installed in mast body 1 both sides, described mast body 1 is made up of three block plates, and its cross section is a triangle, described guide rail 2 is that a monoblock steel plate curves, and is installed in the both sides of mast body 1.Guide rail 2 is that a formation of lots square steel curves, and is simple to operate, and can buy easily from the market.
By the triangle mast body 1 that three block plates are welded into, in light weight, Stability Analysis of Structures, the guide rail 2 of mast body 1 both sides is that a monoblock steel plate curves, can easily guide rail 2 be fixed on the same horizontal plane, efficient is higher during welding, increases work efficiency greatly and work quality.
