Abstract
The utility model discloses a rock drilling machine flower disc device relates to rock drilling machine technical field, it include with the flower disc that has the coaxial setting of open -ended protective shroud, the flower disc is equipped with a plurality of breachs, the breach by the outer fringe of flower disc is inwards seted up the protective shroud with the drilling rod has been placed in the breach, the inner wall of breach has the drive the drive lateral wall of drilling rod, its characterized in that: the drive lateral wall is close to one section of flower disc center have can with the concave part that the drilling rod contacted, the concave part is close to the one end of flower disc outer fringe forms and prizes the convex part of drilling rod. The utility model provides a present rock drilling machine's drilling rod during with the ground out of plumb, the flower disc can't drive the drilling rod brill and move and produce from the pintle hook lock problem of phenomenon extremely.
Description
Technical field
This utility model relates to rock drilling machine component technology field, a kind of device for clamping rock drilling machine drilling rod.
Background technology
Existing a kind of rock drilling machine is that the floral disc by being coaxially disposed and guard ring coordinate to come holding drill pipe, floral disc offers multiple breach for placing drilling rod, these breach lap-ups disk center circular array is arranged, and breach uncovered outwardly, guard ring stacks with floral disc, guard ring has an opening, in addition to guard ring opening part, remaining breach of floral disc is all surrounded by guard ring, thus clamping drilling rod, when changing lever apparatus and carrying out filling bar or unloading bar, floral disc drives drilling rod to rotate, when the floral disc breach at drilling rod place goes to guard ring opening part, drilling rod can be picked and placeed.The shape (i.e. floral disc breach) of floral disc is determined by the movement locus of mechanical hand, and therefore, floral disc breach is misaligned with floral disc center with the seal face of drilling rod (i.e. drive surface), but one angle of deviation.As it is shown in figure 1, when drilling rod 3 and ground out of plumb, drilling rod 3 is in the position shown in figure, due to the effect of drilling rod 3 gravity so that drilling rod 3 is in a wedge gap.Now, floral disc 1 drives drilling rod 3 to rotate counterclockwise, and drilling rod 3 is by the pressure of floral disc 1 drive surface, and the frictional force of guard ring 2 inner cylinder face, and these power create self-locking effect so that drilling rod 3 is stuck, it is impossible to rotate.In order to avoid this situation occurs, it is necessary to reasonably design floral disc breach so that when drilling rod becomes any angle with ground, floral disc drives drilling rod all to occur without locking phenomenon, it is ensured that drilling rod normal rotation.
Utility model content
The purpose of this utility model is to provide a kind of rock drilling machine floral disc device, and when this device can solve the drilling rod of existing rock drilling machine with ground out of plumb, floral disc cannot drive drilling rod to bore problem that is dynamic and that be produced from lock stuck phenomenon.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: this rock drilling machine floral disc device includes the floral disc being coaxially disposed with the guard ring with opening, described floral disc is provided with multiple breach, described breach is inwardly offered by the outer rim of described floral disc, it is placed with drilling rod in described guard ring and described breach, the inwall of described breach has the driving sidewall driving described drilling rod, near a section of described floral disc center, there is the recess that can contact with described drilling rod at described driving sidewall, described recess forms the protuberance prizing described drilling rod near one end of described floral disc outer rim.
In the technical scheme of above-mentioned rock drilling machine floral disc device, more specifically technical scheme is it may also is that the inwall of described recess is arcwall face.
Further, described protuberance is corner angle.
Further, when described drilling rod contacts with described guard ring inwall and described protuberance simultaneously, now the angular range between these two contact points is arrived at the center through the cross section of the described drilling rod of these two contact points respectively is 0 DEG C～90 DEG C.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, the driving sidewall at floral disc arranges recess, and the outer end of recess forms protuberance, and this protuberance produces the effect prized to drilling rod, and under the counteracting force of guard ring inwall, produces the trend to recess motion, thus avoid the phenomenon that self-locking is stuck.
2, the inwall of recess is arcwall face, preferably can fit with drilling rod, increase the contact area driving sidewall and drilling rod during floral disc drives drilling rod transfer, makes driving more equalize, laborsaving.
3, protuberance is corner angle, is conducive to prizing drilling rod.
4, drilling rod axis to guard ring inwall line segment and axis to the angular range between the line segment of protuberance.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing rock drilling machine floral disc device.
Fig. 2 is the structural representation of this utility model embodiment.
Detailed description of the invention
The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings:
Rock drilling machine floral disc device shown in Fig. 2 mainly includes floral disc 4 and the guard ring 5 being coaxially disposed, wherein, floral disc 4 is uniformly provided with the breach 4-1 that multiple shape is identical around center, these breach 4-1 is inwardly offered by the outer rim of floral disc 4, guard ring 5 has an opening matched with breach 4-1, it is placed with drilling rod 6 in the breach 4-1 of floral disc 4, drilling rod 6 is held between guard ring 5 inwall and breach 4-1 inwall, the inwall of breach 4-1 has the driving sidewall driving drilling rod 6, sidewall is driven to have, near a section of floral disc 4 center, the recess 4-4 that can contact with drilling rod 6, recess 4-4 forms the protuberance 4-3 prizing drilling rod 6 near one end of floral disc 4 outer rim.The driving sidewall of the present embodiment is made up of the first straightway 4-2 and recess 4-4, the corner angle that the intersection of the first straightway 4-2 and recess 4-4 is formed are the protuberance 4-3 for prizing drilling rod 6, the other end of recess 4-4 is connected with segmental arc 4-5 and the second straightway 4-6 in turn, the outer end of the second straightway 4-6 extends to the outer rim of floral disc 4, the first straightway 4-2 and the second straightway 4-6 center with floral disc 4 all in eccentric setting.It is noted that when drilling rod 6 contacts with guard ring 5 inwall and protuberance 4-3 simultaneously, now the angle α scope between these two contact points is arrived at the center through the cross section of the drilling rod 6 of these two contact points respectively is 0 DEG C < α < 90 DEG C.
In the work process of this rock drilling machine floral disc device, when drilling rod 6 and ground at an angle time, the effect of the component of gravity suffered by drilling rod 6, drilling rod 6 is pressed on corner angle, when floral disc 4 drives drilling rod 6 to rotate counterclockwise, guard ring 5 inwall produces frictional force to drilling rod 6, drilling rod 6 is hindered to rotate, and produce the tendency of self-locking, and the corner angle of floral disc 4 produce the effect prized to drilling rod 6, and under the counteracting force of guard ring 5 inwall, produce the trend to recess 4-4 motion, thus avoid the phenomenon that self-locking is stuck, it is ensured that drilling rod normal rotation.
