Abstract
The utility model discloses a lower supporting seat for a drill pipe of a drilling machine. The lower support seat comprises a horizontal plate (1), a vertical plate (2) and a sleeve (4); the horizontal plate (1) is fixed with the vertical plate (2) to form into an L-shaped structure; a mounting hole is formed on the horizontal plate (1), wherein the mounting hole on the horizontal plate (1) is provided with a fixing sleeve (5) for fixing the sleeve (4); the sleeve (4) is mounted in the fixing sleeve (5); flange plates (3) are installed on the upper and lower surfaces of the fixing sleeve (4) through bolts; the flange plates (3) consist of two semicircular sub-flange plates (3a); the sleeve (4) is packed by the flange plates (3); the upper part of the sleeve (4) extends out of the above flange plate (3); and the length of the sleeve (4) extending out of the flange plate (3) is 5-10 cm.
Description
Technical field
The utility model relates to a kind of hydraulic high-speed drill member, especially relates to the drilling rod lower support seat on a kind of rig.
Background technology
The lower support seat is installed on the drill boom, passes for drilling rod, and drilling rod is played supporting and guiding; Traditional drilling rod lower support seat is made up of level board, vertical plate and sleeve; Wherein level board and vertical plate fix, and form L shaped structure, on level board, establish installing hole; Sleeve is located in this installing hole, establishes bearing between supporting base and the sleeve.Above structure, vertical plate is fixed through bolt and drill boom, and sleeve is passed in the lower end of drilling rod, and then rotation of sleeve in the time of the drilling rod rotation.Adopt this mode, because the operating mode of rig work is abominable, bearing lubrication is not good, and is fragile, and it is inconvenient to change bearing.And sleeve follows drilling rod to rotate together, and polarization is poor.The sleeve of existing in addition lower support seat is very short, and its upper end can not be stretched out flange or only stretched out flange 1-2 centimetre, and such structure is inconvenient to locate, and guide effect is bad.
The utility model content
The utility model technical problem to be solved is the borer drill rod lower support seat that provides a kind of polarization good.
The technical scheme of the utility model is following: a kind of borer drill rod lower support seat; Comprise level board (1), vertical plate (2) and sleeve (4); Wherein level board (1) fixes with vertical plate (2); Form " L " shape structure, said level board offers installing hole on (1), is provided with the fixed cover (5) of fixed muffle (4) in the installing hole on the said level board (1); The interior installing sleeve of this fixed cover (5) (4); The upper and lower surface of said fixed cover (5) is installed flange (3) and lower flange (3-1) respectively through bolt, and said upper flange plate (3) and lower flange (3-1) are by two semicircular minute flange (3a) compositions, said upper flange plate of said sleeve (4) outerwrap (3) and lower flange (3-1); Upper flange plate (3) is stretched out on the top of said sleeve (4), and the length that said sleeve (4) stretches out the outer part of upper flange plate (3) is 5-10 centimetre.
Adopt technique scheme, adopt the axle sleeve location, drilling rod rotates in axle sleeve, and axle sleeve wearing and tearing back is directly changed, and it is convenient to change.Adopt the axle sleeve of lengthening in addition, guide effect is better.
In technique scheme; The bottom of said level board (1) is welded with mud cover (6); Said mud cover (6) is a conical structure, and lower flange (3-1) cover is gone into wherein, and sleeve pipe (7) is set in said mud cover (6); The axis of axis of this sleeve pipe (7) and sleeve (4) point-blank, mud cover (6) is stretched out in the lower end of this sleeve pipe (7).Adopt above structure, around the dust that mud cover can will drill produces presses to, prevent that dust to the boring falling, adopting obconic mud cover, it extrudes the better effects if of dust.Sleeve pipe combines with sleeve, to strengthen the guided bearing effect to drilling rod.
In technique scheme: be welded with two stiffeners that are parallel to each other (8) between said level board (1) and the vertical plate (2).
Beneficial effect: the utility model is reasonable in design, simple in structure, easy to assembly, guide effect is good, deslagging is effective.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As illustrated in fig. 1 and 2; The utility model is made up of parts such as level board 1, vertical plate 2, upper flange plate 3, lower flange 3-1, sleeve 4, fixed cover 5, mud cover 6, sleeve pipe 7 and stiffeners 8; Wherein level board 1 welds with vertical plate 2 mutually; Form " L " shape structure, and between level board 1 and vertical plate 2, be welded with two stiffeners that are parallel to each other 8, to increase bonding strength.Central authorities at said level board 1 offer installing hole; In this installing hole, be welded with fixed cover 5, installing sleeve 4 in the fixed cover 5 is installed flange 3 and lower flange 3-1 on the upper and lower surface of said fixed cover 5 respectively through bolt; Said upper and lower flange 3,3-1 form by two semicircular minute flange 3a; Said upper flange plate of said sleeve 4 outerwrap 3 and lower flange 3-1, during installation, the gap between two branch flange 3a seals with glass cement.Stretch out outside the upper flange plate 3 on the top of said sleeve 4, and the length that said sleeve 4 stretches out the part outside the upper flange plate 3 is 5-10 centimetre, to increase guide effect.The bottom of said level board 1 is welded with mud cover 6; Said mud cover 6 is a conical structure; And lower flange 3-1 covered into wherein, in said mud cover 6, sleeve pipe 7 being set, the axis of the axis of this sleeve pipe 7 and sleeve 4 is point-blank; And said sleeve pipe 7 welds with said mud cover 6 mutually, and stretch out outside the mud cover 6 lower end of this sleeve pipe 7.
