Description

Small-resistance spline gun barrel impactor

Technical Field

The utility model relates to an strike drilling equipment technical field, especially relate to low resistance spline gun barrel impacter.

Background

The impacter gun barrel is basic equipment needed to be used in drilling engineering, but the excircle structural shapes of the conventional impacter gun barrels in the current market are uniform and are all cylindrical structures, the cylindrical structure is single, and the cylindrical gun barrel has large contact area with a rock stratum and large resistance in the rock drilling process, so that the smooth drilling work is not facilitated, and the difficulty is increased for the operation; and the sealing performance is poor, so that the impact efficiency is reduced, and certain energy is wasted in the stamping process.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a small resistance spline gun barrel impacter can solve the problems of large drilling resistance, low impact force and energy waste.

In order to solve the technical problem, the utility model provides a following technical scheme:

the small-resistance spline gun barrel impactor comprises an impactor body, wherein the impactor body comprises a front joint, a spline gun barrel and a rear joint, the front joint is arranged at the bottom of the spline gun barrel, the rear joint is arranged at the top of the spline gun barrel, and a spline groove is formed in the outer wall of the spline gun barrel.

As a preferred technical scheme of the utility model, the vertical evenly distributed in spline groove is in spline barrel outer wall, spline groove quantity sets up to eight, spline groove size equals.

As a preferred technical scheme of the utility model, the front connection passes through threaded connection with the spline gun barrel, the back connects the bottom and passes through threaded connection with the spline gun barrel, back connects the inner wall top and is provided with internal thread and recess, recess evenly distributed is on the front connection.

As an optimal technical scheme of the utility model, front connector, spline gun barrel, rear joint are the cavity structure, front connector, spline gun barrel, rear joint are made by high strength steel material.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is: the utility model has novel structure, light weight and strong impact force, and is suitable for large-area popularization and use; by the spline grooves formed in the spline gun barrel, the contact area between the spline gun barrel and a rock stratum can be reduced, the resistance is reduced, the impact efficiency is improved, and the manufacturing cost is reduced; and the groove and the internal thread arranged on the rear joint enable the sealing performance of the impactor to be better. Thereby improving the impact strength and avoiding energy waste.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

As shown in fig. 1-3, the utility model provides a low resistance spline barrel impacter, including impacter body 2, impacter body 2 includes front joint 7, spline barrel 1, rear joint 3, and front joint 7 sets up in spline barrel 1 bottom, and rear joint 3 sets up in spline barrel 1 top, has seted up spline groove 6 on the 1 outer wall of spline barrel.

The vertical evenly distributed in spline barrel 1 outer wall of spline groove 6, spline groove 6 quantity sets up to eight, and 6 size of spline groove equals, reduces the resistance of probing in-process through spline groove 6.

The front connector 7 is in threaded connection with the spline gun barrel 1, the bottom end of the rear connector 3 is in threaded connection with the spline gun barrel 1, internal threads 4 and grooves 5 are arranged at the top end of the inner wall of the rear connector 3, and the grooves 5 are uniformly distributed on the front connector 7, so that the sealing performance is improved.

The front joint 7, the spline gun barrel 1 and the rear joint 3 are all of a cavity structure, the front joint 7, the spline gun barrel 1 and the rear joint 3 are all made of high-strength steel materials, and an airflow channel with impact force is formed in the cavity.

Specifically, the impactor comprises a front joint 7, a spline gun barrel 1 and a rear joint 3, wherein the front joint 7, the spline gun barrel 1 and the rear joint 3 are connected through threads, cavity structures are formed among the front joint 7, the spline gun barrel 1 and the rear joint 3, and a ventilation channel can be formed inside the cavity structures; through being connected back connector 3 with the drill bit, front connector 7 is connected with the wind pressure equipment through internal thread 4 of upper end, forms sealed airflow channel to accomplish the work of punching press drilling, recess 5 that sets up on the internal thread 4 of back connector 3 can make wind pressure equipment be connected with the impacter more stable, thereby has ensured airflow channel's gas tightness, makes the punching press effect better.

The embodiments of the present invention are not limited to the above embodiments, and according to the contents of the above embodiments of the present invention, the above preferred embodiments can also make modifications, replacements or combinations of other forms by using conventional technical knowledge and conventional means in the field without departing from the basic technical idea of the present invention, and the obtained other embodiments all fall within the scope of the present invention.
