Description
Technical field
The utility model technology relates to a kind of column of engineering driller and the novel coupling mechanism that base links, and is particularly a kind of simple to operate, quick, firm, and column is the novel coupling mechanism of 45 ° of maximum inclination backward.
Background technology
In fields such as building, finishing, piping erection, often use engineering driller on stone material, brick body or concrete, to hole.At present the column of the existing engineering driller of China connects with base, mostly adopts simple Bolt Connection mechanism, as shown in Figure 9, with bolt (10) column (1) is fixed on the base (2).Column (1) becomes a firm integral body with base (2), and column (1) is vertical with the bottom surface of base (2).When the stationary plane of engineering driller was vertical with the hole that will bore, it was fairly simple to operate.If but during the stationary plane out of plumb of the hole that will bore and engineering driller, corresponding object on just need be below the base suitable position pad, it is not too convenient to operate.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of column of engineering driller and the novel coupling mechanism that base links are provided, particularly a kind of simple to operate, quick, firm, column is the novel coupling mechanism of 45 ° of maximum inclination backward, for engineering construction provides convenience.
The utility model is achieved through the following technical solutions: the novel coupling mechanism that a kind of column of engineering driller and base link, form by column and base, pass column and base the tapered stud rotating shaft is installed, tapered stud rotating shaft left end is installed with the locking pulling block; The right side of base positioning key with two screw; Thin steel bushing and crude steel cover are housed in the vertical hole of chassis left side, in thin steel bushing and the crude steel cover eccentric lock mandrel are installed.
Described column bottom is provided with a horizontal bellmouth.
Described base is provided with the two through hole of horizontal direction, and two through hole is coaxial; Chassis left side is provided with the through hole and the blind hole of vertical direction, and through hole and blind hole are coaxial; The base right side is provided with keyway, and the keyway two ends respectively are provided with a screwed hole.
Described tapered stud rotating shaft left end is provided with screwed hole, and right-hand member is provided with keyway.
Described locking pulling block left side is provided with slotted hole, and the right side is provided with thread segment.
The hypomere and the epimere of described eccentric lock mandrel are coaxial, eccentric segment and hypomere, epimere disalignment; Eccentric lock mandrel top is provided with six sides section.
The beneficial effects of the utility model: it is inaccurate that the novel coupling mechanism that the column of engineering driller and base link has solved existing engineering driller bore angle, deficiencies such as inconvenient operation, provide a kind of simple to operate, quick, firm, column is the novel coupling mechanism of 45 ° of maximum inclination backward, for engineering construction provides convenience.

The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in Figure 1: the utility model is made up of column 1 and base 2, passes column 1 and base 2 is installed with tapered stud rotating shaft 3, and tapered stud rotating shaft 3 left ends are installed with locking pulling block 4; Positioning key 6 is being fixed with two screws 5 in the right side of base 2; Thin steel bushing 7 and crude steel cover 8 is housed in the vertical hole in base 2 left sides, in thin steel bushing 7 and the crude steel cover 8 eccentric lock mandrel 9 is installed.
As shown in Figure 2: column 1 bottom is provided with a horizontal bellmouth 1a.
As shown in Figure 3 and Figure 4: base 2 is provided with the through hole 2a and the through hole 2b of horizontal direction, and through hole 2a and through hole 2b are coaxial; Base 2 left sides are provided with the through hole 2c and the blind hole 2d of vertical direction, and through hole 2c and blind hole 2d are coaxial; Base 2 right sides are provided with keyway 2e, and keyway 2e two ends respectively are provided with a screwed hole 2f.
As shown in Figure 5 and Figure 6: tapered stud rotating shaft 3 left ends are provided with screwed hole 3a, and right-hand member is provided with keyway 3b.
As shown in Figure 7: locking pulling block 4 left sides are provided with slotted hole 4a, and the right side is provided with thread segment 4b.
As shown in Figure 8: the hypomere 9a and the epimere 9b of eccentric lock mandrel 9 are coaxial, eccentric segment 9c and hypomere 9a, epimere 9b disalignment; Eccentric lock mandrel 9 tops are provided with six sides section 9d.
When the base of column 1 and base 2 was vertical, novel coupling mechanism kept state shown in Figure 1, and eccentric lock mandrel 9 passes the slotted hole 4a of locking pulling block 4; Positioning key 6 is stuck among the keyway 3b of tapered stud rotating shaft 3 right-hand members.At this moment, block the six sides section 9d of eccentric lock mandrel 9 with spanner, rotate eccentric lock mandrel 9, make eccentric segment 9c tightly withstand the left side of the slotted hole 4a of locking pulling block 4, locking pulling block 4 will spur tapered stud rotating shaft 3 and be moved to the left, the bellmouth 1a of column 1 holds the outside conical surface of tapered stud rotating shaft 3 tightly, and it is locked to produce the conical surface.Key 6 blocks because tapered stud rotating shaft 3 is positioned, and can not relatively rotate with base 2, so column 1 can not relatively rotate with base 2.Column 1 has been fixed on base 2.
When needing to rotate column 1, elder generation's backward rotation eccentric lock mandrel 9, make eccentric segment 9c tightly withstand the right side of the slotted hole 4a of locking pulling block 4, locking pulling block 4 will withstand tapered stud rotating shaft 3 and move right, column 1 will be thrown off with the locked place of the conical surface of tapered stud rotating shaft 3, and column 1 just can rotate.After column 1 turns to and is fit to angle, locked again more novel coupling mechanism, engineering driller just can have been started working.
