Abstract
A rope medium-length hole drilling tool locking device is characterized by being composed of an external spline drilling pipe, a locking unit, a position stopping device and a reamer. The taper extrusion expansion principle is adopted, when a drilling tool works, rising thrust producedby the external spline drilling pipe is converted into transverse tension through the locking device, a locking device spring piece enters a reamer groove, rising thrust produced by the external spline drilling pipe is effectively stopped, the purpose of locking is attained, and thus the drilling tool is protected from being damaged by the rising thrust produced by the external spline drilling pipe.
Description
Technical field
The present invention relates to a kind of engineering machinery (rig, drilling tool), especially relate to a kind of rope medium-length hole drilling tool locking device.
Background technology
At present, rope medium-length hole drilling tool is made up of internal spline drilling tool, external splines drilling tool and interior pipe assembly at home, the rising thrust produced when this drilling rod deficiency is that external splines drilling tool works is single is kept off by the bullet jam on interior pipe assembly, thus bullet card and associated member damage too fast, the defects such as drilling tool accident is occurred frequently, efficiency is low.
Summary of the invention
The object of the invention is: a kind of locking device is provided, effectively improve drilling tool application life.
Technical scheme of the present invention is: comprise the part compositions such as reamer, T-shaped position-arresting device, locker and external splines drilling rod, the rising thrust produced by external splines drilling rod, promotes locker and converts horizontal tension to realize work.
Reamer: reamer belongs to internal spline drill section, and lower end is provided with external screw thread, and upper end is provided with internal thread, outside is provided with reaming sheet, and inside is provided with matrix circle.
T-shaped position-arresting device: pipe assembly parts in T-shaped position-arresting device belongs to, upper end is provided with bullet card installation portion, and inside, lower end is provided with internal thread, and T stage rank place is provided with matrix circle, and outside is evenly distributed with tank.
Locker: upper clamp ring, a sheet, lower clamping composition, fixed by bolt or riveting method activity, be provided with groove above a sheet, O type spring fitting opens sheet at groove internal fixtion.
External splines drilling rod: external splines drilling rod belongs to external splines drill section, and lower end is provided with internal thread, and outside is provided with external splines, and upper end is provided with locating ring, locating ring inside is provided with salvaging ring, and top is provided with scrobicular ring.
Locker working method: external splines drilling rod, locker are connected with T-shaped position-arresting device, external splines drilling rod rising thrust and T-shaped position-arresting device stop up, locker is subject to bidirection press, locker is opened sheet and is outwards expanded and enter the inner matrix circle of reamer, thus external splines drilling rod produces rising thrust is reached by locker conversion kinetic energy and laterally lock object, locker can be arranged on T-shaped position-arresting device or external splines drilling rod form and integrally realize locking work.
The invention has the beneficial effects as follows: the present invention adopts tapered squeezing dilating principle; during drilling tool work, external splines drilling rod produces the thrust risen and is converted into horizontal tension by locker; locker shell fragment enters reamer groove; the rising thrust that effective stop external splines drilling rod produces reaches locking object; thus protection damages drill tool life because external splines drilling rod produces rising thrust; extend drilling tool application life, improve business efficiency.

Detailed description of the invention
From location view of the present invention shown in Fig. 1, T-shaped position-arresting device 2, locker 3 are connected with external splines drilling rod 4, and reamer 1 is mounted externally.
From reamer 1 half sectional view of the present invention shown in Fig. 2, reamer 1 belongs to internal spline drill section, and lower end is provided with external screw thread, and upper end is provided with internal thread, and outside is provided with reaming sheet, and inside is provided with matrix circle.
From T-shaped position-arresting device half sectional view of the present invention shown in Fig. 3, Fig. 4, T-shaped position-arresting device 2 belongs to interior pipe assembly parts, and upper end is provided with bullet card installation portion, and inside, lower end is provided with internal thread, and T stage rank place is provided with matrix circle, and outside is evenly distributed with tank.
From external splines drilling rod half sectional view of the present invention shown in Fig. 5, external splines drilling rod 4 belongs to external splines drill section, and lower end is provided with internal thread, and outside is provided with external splines, and upper end is provided with locating ring, and locating ring inside is provided with salvaging ring, and top is provided with scrobicular ring.
From locker view of the present invention shown in Fig. 6, Fig. 7, upper clamp ring 5, a sheet 6, lower clamping 7 form, and fixed by bolt or riveting method activity, be provided with groove above a sheet 6, O type spring fitting opens sheet 6 at groove internal fixtion.
From the present invention shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, locker 3 working method: external splines drilling rod 4, locker 3 are connected with T-shaped position-arresting device 2, external splines drilling rod 4 produces rising thrust and T-shaped position-arresting device 2 stops up, locker is subject to bidirection press, sheet outwards expands and enters the inner matrix circle of reamer, thus external splines drilling rod produces rising thrust is reached by locker conversion kinetic energy and laterally lock object.Locker 3 can be arranged on T-shaped position-arresting device 2 or external splines drilling rod 4 form and integrally realize locking work.
