Abstract

The utility model provides a dedicated drill stem for a wind power generation bearing hole. The dedicated drill stem for the wind power generation bearing hole comprises a side cutter fixing handle, a cutter handle connecting part, chip grooves, a spotter and an indexable blade. The cutter handle connecting part is arranged on the side cutter fixing handle. The cutter handle connecting part is provided with the ship grooves. The chip grooves are provided with chip groove cooling holes. The chip grooves are provided with the spotters and the indexable blade. The indexable blade surrounds the spotter. Cooling holes are arranged in the indexable blade which surrounds the spotter. Cooling liquid deviding holes are formed between the spotter and the chip grooves. The mechanical strength and the heat dissipation capability of the drill rod are greatly improved by designing the dedicated drill stem for the wind power generation bearing and improving the structure of the existing drill rod for the bearing hole.

Description

A kind of wind-power electricity generation dead eye drill rod special

Technical field

The utility model relates to the drilling rod field, particularly a kind of wind-power electricity generation dead eye drill rod special.

Background technology

The wind-power electricity generation dead eye is very high to the required precision in hole, therefore require very high to the drilling rod mechanics in machining bearing hole, and because requirement on machining accuracy is high, need successively processing, therefore require also very high to the thermal diffusivity of drilling rod, present employed power generating electricity consumption bearing drilling rod is general drilling rod, and the mechanical strength thermal diffusivity is often inadequate.

The utility model content

For above problem, the utility model is by a kind of wind-power electricity generation dead eye drill rod special of design, by existing dead eye jackrod structure is improved, thereby mechanical strength and the thermal diffusivity of drilling rod have greatly been improved, for reaching this purpose, the utility model provides a kind of wind-power electricity generation dead eye drill rod special, described wind-power electricity generation dead eye drill rod special comprises the solid handle of a knife of side, the handle of a knife coupling part, chip area, pilot drill and indexable insert tip, throw away tip, described handle of a knife coupling part is arranged on the solid handle of a knife of side, described handle of a knife has chip area on the coupling part, the chip area Cooling Holes is arranged in the described chip area, pilot drill and indexable insert tip, throw away tip are arranged on the described chip area, described indexable insert tip, throw away tip is around pilot drill, and is described around in the indexable insert tip, throw away tip Cooling Holes being arranged around the pilot drill, and the cooling fluid tap hole is arranged between described chip area and the pilot drill.

As further improvement of the utility model, there is the solid handle of a knife of side that the inclined-plane is installed on the solid handle of a knife of described side, the installation inclined-plane is set can be convenient to the drilling rod installation.

The utility model is a kind of wind-power electricity generation dead eye drill rod special, by existing dead eye jackrod structure is improved, thereby has greatly improved the mechanical strength of drilling rod, and this patent increases Cooling Holes at the drilling rod diverse location in addition, thereby improves the thermal diffusivity of drilling rod.
