Abstract
The utility model provides a vertical shaft type drill capable of mechanically screwing down a drill stem. A pair of gears installed in a rotation box body can transmit rotation power of an output shaft of a speed change box connected with a motor to a vertical shaft, a pair of cylindrical gears can transmit rotation of a slide shaft sleeve to a drill stem spindle parallel to the vertical shaft, a chuck for clamping the drill stem is fixed under the spindle, the chuck can driven the drill stem and the spindle to rotate together, a clamp capable of clamping the drill stem is fixed on the rotation box body under the chuck, and a drill stem connector between two sections of drill stems is positioned between the chuck and the clamp. When the chuck clamps the drill stem and the clamp loosens, the drill stem can forwards rotate to drill. When the chuck and the clamp simultaneously clamp the drill stem, the chuck reversely rotates to screw down the drill stem connector. The vertical shaft type drill has the advantages of being capable of using a long drill stem to drill and a short drill stem to drill, being suitable for being used on the ground and in underground tunnels, being suitable for drilling in a multi-angle mode and being capable of screwing down the drill stem in a non-manual mode in non-vertically drilling. When the drill stem is screwed down, a drill stem column in a hole cannot rotate so as to be small in friction resistance.
Description
Technical field
The utility model belongs to the rig field in engineering machinery.Relate in particular to a kind of spindle-type drill that can mechanical unloading drilling rod for the earth-borings such as geological prospecting, tunnel probing constructions.
Background technology
The geological prospecting rig is mainly spindle-type drill and all-hydraulic drill, and the integral layout of all-hydraulic drill is more flexible, complete function, and machine automatization unloading drilling rod has replaced manpower unloading drilling rod, and is time saving and energy saving.Spindle-type drill is because structure limits, machine automatization unloading drilling rod is more difficult, existing method one is to adopt hydraulic casing screwing machine, but this method is only applicable to vertical drilling and inapplicable level or other angular hole-borings, method two is to adopt three chuck rigs, forward unloading drilling rod, the problems such as drill string frictional resistance is too large in the hole when also having the oversize and unloading drilling rod of chuck string.
The utility model content
For overcoming the above defective of prior art, the utility model provides a kind of spindle-type drill of simple in structure, easy to use and reliable mechanical unloading drilling rod.
other parts of spindle-type drill that can mechanical unloading drilling rod of the present utility model are identical with common spindle-type drill, realization can mechanical unloading drilling rod structure be: with a pair of gear that is arranged in the revolution casing, the rotary power of the output shaft of the gearbox that will be connected with motor passes to vertical shaft, be set with the slide-bar cover that can slide up and down along vertical shaft on vertical shaft, the slide-bar cover can be with vertical shaft rotary, by a pair of roller gear, the rotation that slide-bar overlaps is passed to the drilling rod main shaft parallel with vertical shaft, the drilling rod main shaft is interior hollow shaft of overlapping stacks, drilling rod main shaft below is fixed with the chuck for the chucking drilling rod, chuck can drive drilling rod and rotate together with main shaft.Such setting makes drilling rod and vertical shaft not on same straight line, the installation site is provided for mechanical unloading device; Simultaneously drilling rod is parallel with vertical shaft, has also realized in the prior art drilling rod and the vertical shaft function of synchronous rotary in the same way.Have below chuck be fixed on the gyrator casing can holding drill pipe clamper.Tool joint between two sections drilling rods is between chuck and clamper.
The motion mode of this mechanism is: motor drives shaft coupling, gearbox, and by the train of gearbox inside, power is exported from output shaft of gear-box, is passed to chuck through gear, vertical shaft, roller gear, and chuck is clamped drilling rod and is rotated.See from top to bottom, drilling rod clockwise rotates and is forward, rotates counterclockwise to be counter-rotating.Chuck clamps drilling rod, and clamper unclamps, and the drilling rod forward is crept into; Chuck and clamper clamp drilling rod simultaneously, the chuck counter-rotating, and tool joint is unscrewed.
As preferred version, the sliding sleeve axle is hollow shaft, and endoporus is hexagonal hole or other non-circular holes, and vertical shaft and sliding sleeve axle the match cross section of part is for corresponding six side's or other non-circular shapes.
As preferred version, motor, gear-box and output shaft thereof are arranged horizontally, and being arranged on a pair of gear of revolution in casing is conical gear, and the rotary power of the output shaft of horizontal direction is passed to the vertical shaft vertical with output shaft.
Its beneficial effect is: 1, can adopt long drill pipe to creep into, also can adopt short drill pipe to creep into, be adapted at using in ground and tunnel, be fit to multi-angle drilling.2, can be with unartificial mode unloading drilling rod when non-perpendicular boring.3, during the unloading drilling rod, in the hole, drill string does not rotate, and frictional resistance is little.
