Abstract
The utility model discloses a guider, which comprises a supporting base (1), wherein an upper pedestal (2) and a lower pedestal (3) are arranged on the supporting base (1); one end of the upper pedestal (2) is connected with one end of the lower pedestal (3) through a rotary pin (4); at least two bearing frames (5) are respectively arranged in the upper pedestal (2) and the lower pedestal (3); and the circle centres of the bearing frames (5) are at the same periphery. The guider has the advantages of ingenious structural design, safety and reliability and plays a role of positioning and guiding; the frictional factor is reduced; and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of directional orientation tool, particularly a kind of rig, rod guide that is used under the coal mine.
Background technology
At present, general rig or the drilling rod of adopting carries out the exploitation of coal under coal mine, when exploiting, because the length of the drilling rod of rig is longer, for the drilling rod to rig positions and leads, adopted guider, existing guider mainly comprises sleeve and pony sill, sleeve is fixed on the pony sill, drilling rod passes sleeve, though do the effect that can play location and guiding like this, owing to be sliding friction between drilling rod and the sleeve, caused friction factor excessive, sleeve damages easily.
The utility model content
The purpose of this utility model just provides the little guider of a kind of friction factor.
The purpose of this utility model is to realize by such technical scheme, a kind of guider, described guider comprises supporting seat, supporting seat is provided with upper bed-plate and lower bottom base, one end of described upper bed-plate is connected with an end of lower bottom base by rotational pin, be respectively arranged with at least two bearing bracket stands in upper bed-plate and lower bottom base, the center of circle of described bearing bracket stand is that the center of circle is positioned on the same circumference with the center of guider.
Wherein, the cross section of described upper bed-plate and lower bottom base is the U type, and the described bearing bracket stand that is positioned at upper bed-plate all passes upper bed-plate and lower bottom base with the bearing bracket stand that is positioned at lower bottom base.
Further, the structure of described bearing bracket stand is such: described bearing bracket stand comprises bearing shaft, on the two ends of bearing shaft and be positioned at upper bed-plate or lower bottom base is respectively arranged with jacket casing, bearing shaft is provided with the bearing shell, and an end of described bearing shaft is provided with lubricating cup.
In order to lock upper bed-plate and lower bottom base, described junction at upper bed-plate and lower bottom base is provided with locking device.
Wherein, described locking device comprises locking bed, and locking bed is provided with lock bolt, and lock bolt is provided with locking member.
Owing to adopted technique scheme, the utlity model has ingenious, the safe and reliable advantage of structure design, adopt it not only can play the effect of location and guiding, but also reduced friction factor, improved application life.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, a kind of guider, described guider comprises supporting seat 1, supporting seat 1 is provided with upper bed-plate 2 and lower bottom base 3, one end of described upper bed-plate 2 is connected with an end of lower bottom base 3 by rotational pin 4, be respectively arranged with at least two bearing bracket stands 5 in upper bed-plate 2 and lower bottom base 3, the center of circle of described bearing bracket stand 5 is that the center of circle is positioned on the same circumference with the center of guider.
Further, the cross section of above-mentioned upper bed-plate 2 and lower bottom base 3 is the U type, and the described bearing bracket stand 5 that is positioned at upper bed-plate 2 all passes upper bed-plate 2 and lower bottom base 3 with the bearing bracket stand 5 that is positioned at lower bottom base 3.
Wherein, above-mentioned bearing bracket stand 5 comprises bearing shaft 6, and on the two ends of bearing shaft 6 and be positioned at upper bed-plate 2 or lower bottom base 3 is respectively arranged with jacket casing 7, bearing shaft 6 is provided with bearing shell 8, and an end of described bearing shaft 6 is provided with lubricating cup 9.
Wherein, be provided with locking device in the junction of upper bed-plate 2 and lower bottom base 3.Described locking device comprises locking bed 10, and locking bed is provided with lock bolt 11, and lock bolt 11 is provided with locking member 12.
The utility model is to use like this: at first, unclamp locking member, pull upper bed-plate 2, upper bed-plate 2 is upwards opened along rotational pin 4, then the drilling rod of rig is put into the centre of four bearing bracket stands 5, last, with upper bed-plate 2 returns, locking upper bed-plate 2 and lower bottom base 3 get final product.The drilling rod of rig is when rotating, and bearing bracket stand 5 rotates along with the friction of the drilling rod of rig, so just can control the track of drilling rod axiality, has reduced the drilling rod of rig and the frictional resistance of guider.
