Specific embodiment
The specific embodiment of the present invention is illustrated with reference to accompanying drawing.
A kind of drill carriage drill boom rock drill holds out against special universal three-jaw top pricker, and by pedestal 1, holder 2, localizer 3 are constituted, its
Middle pedestal 1 is arranged on the mechanical arm of drill carriage drill boom rock drill end, and the center portion thereof position is hollow, is available for the drill bit of rock drill to stretch
Cross, one semicircular localizer 3 of back-off on pedestal 1, localizer 3 are fixed on pedestal 1 by holder 2.Drill carriage drill bit from
The centre of sphere of universal three-jaw top pricker passes through, and is so achieved that containing of the three-jaw top pricker to drill bit.
Pedestal 1 supports hemisphere 1-2, base threaded bore 1-3, pedestal to hold drilling 1-4 compositions by fixed seat 1-1.Wherein, Gu
Reservation 1-1 is mainly used to realize that drill carriage drill boom rock drill is held out against special universal three-jaw top pricker and is connected with drill carriage mechanical arm, fixed seat
1-1 is arranged on the end of drill carriage drill boom, and a hemispheric support hemisphere 1-2 is arranged at its top, has one at the centre of sphere for supporting hemisphere
The individual pedestal through fixed seat 1-1 and the cylinder for supporting hemisphere 1-2 holds drilling 1-4, and pedestal holds drilling 1-4 and is mainly used to realize
Containing of the pedestal 1 to drill carriage drill bit, the heart is passed freely through wherein can to make drill bit, and then realizes bag of the three-jaw top pricker to drill carriage drill bit
Hold, to strengthen overall stability.Several base threaded bore 1-3s, base threaded bore are evenly arranged around hemisphere 1-2 supporting
1-3 is used for realizing installation of the holder 2 on pedestal 1.
Holder 2 is by holder pedestal 2-1, fixed mount 2-2, holder unthreaded hole 2-3 composition.Wherein, holder pedestal
The upper intrinsic fixed mount 2-2 of 2-1, fixed mount 2-2 are one section of hollow hemispheres, the external diameter phase of hemispheroidal internal diameter and place kick 3-1
Together, its centre of sphere with support hemisphere 1-2 the centre of sphere overlap, fixed mount 2-2 localizer 3 can be fixed on pedestal 1 and guarantee its
1 cofree rotation of pedestal.It is evenly arranged around fixed mount 2-2 and base threaded bore 1-3 number identical holder unthreaded holes
2-3, to realize the fixation between holder 2 and pedestal 1.
Localizer 3 is that, by place kick 3-1, locating detent 3-2, localizer hold drilling 3-3 compositions.Wherein place kick 3-1 is one
Individual hollow hemisphere, its sphere internal diameter are identical with the external diameter for supporting hemisphere 1-2, and external diameter is identical with the internal diameter of fixed mount 2-2, so fixed
Position ball 3-1 can be buckled on support hemisphere 1-2 and is fixed on pedestal 1 by holder 2.As place kick 3-1 is one empty
The hemisphere of the heart, therefore localizer 3 can be freely rotated relative to pedestal, and the angle for rotating can pass through the hemisphere of place kick 3-1
Size is determining.Equally, a cylindrical localizer also holds drilling 3-3 in the end of place kick 3-1, the diameter in its hole is omited
Hold drilling 1-4 more than pedestal, for realizing the containing to drill bit and localizer 3 and drill bit being prevented when localizer 3 is freely rotated
Interfere.On place kick 3-1, there are three uniform locating detent 3-2, locating detent 3-2 that drilling can be held out against when rock drill works
The work surface of operation, and then ensure the compression and positioning of drilling rod.
In work, universal three-jaw top pricker is arranged on the drill boom end of drill carriage drill boom rock drill first, and drill bit is put
Such as accompanying drawing 8 in appearance drilling 1-4.Drill boom is run to the place specified, and progressively holds out against section.The now locating detent of three-jaw top pricker
3-2 starts from section contact.Due to the shape of section it is uneven, it is thus possible to can first have a locating detent 3-2 to contact first
Section, drill boom continue to hold out against forward.With holding out against for drill boom, place kick 3-1 can produce a rotation relative to pedestal 1, this
Sample second locating detent 3-2 in the state of previous locating detent 3-2 holds out against section moves forward until hold out against section, with
In the presence of drill boom pressure, place kick 3-1 continues rotation afterwards, until the 3rd locating detent 3-2 holds out against section, thus realizes
Drill bit is surrounded and holds out against the work of section by three locating detent 3-2.
A plane is in when the front end of the locating detent 3-2 of universal three-jaw top pricker is initial, when section is plane, three fixed
Position pawl 3-2 can be contacted with section simultaneously and be held out against, and when section is uneven, universal three-jaw top pricker as noted above progressively can be pushed up
Tight section.When the hump of section is big with trench phase declinate, universal three-jaw top pricker is to guarantee the precision for positioning and give up automatically meeting
Produce the locating detent 3-2 of larger deflection and adopt two pawl top pricker positioning, can also be manually adjusted certainly, by universal three-jaw top pricker
Around bit, select suitable position location to improve overall positioning precision.
