Abstract

The present invention relates to a bush structure for guiding a pipe, which surrounds the outer circumferential surface of a vertically elevating pipe (5) in order to guide the elevation of the pipe (5). The bush comprises: an inner pipe body (10) which surrounds the outer circumferential surface of the pipe (5) in order to perform a lubrication function; and an outer pipe body (20) which closely surrounds the outer circumferential unit of the inner pipe body (10). The bush structure for guiding a pipe, capably of guiding the elevation of the pipe by surrounding the outer circumferential surface of the vertically elevating pipe, is separated into the inner pipe body which surrounds the outer circumferential surface of the pipe and the outer pipe body which closely surrounds the outer circumferential unit of the inner pipe body. The inner pipe body is formed of a copper material and the outer pipe body is formed of a steel material. Therefore, the bush structure can save costs by replacing only the inner pipe body which may wear by friction with the pipe.

[0001] Bush structure for guiding of pipe [0002]

[0001] The present invention relates to a bushing structure for a pipe guide, and more particularly, to a bushing structure for a pipe guide, which comprises a pipe for guiding the lifting and lowering of the pipe around an outer circumferential surface of a pipe moved up and down, The inner tube is made of a copper material and the outer tube is made of a steel material so that only the inner tube consumed by the friction with the pipe can be replaced and replaced with the outer tube, So that the cost can be reduced.

Generally, the bush for a pipe guide is a part for guiding the smooth ascending and descent of the pipe by wrapping around the outer peripheral surface of the pipe which is moved up and down.

Such a bush is a short pipe structure having a constant thickness, and a copper material or the like having excellent lubrication function is used in order to minimize frictional force with a pipe vertically lifted and lowered along the inner circumferential surface thereof.

However, since the conventional bush structure for a pipe guide is made of a single material such as a copper material, if the bush is to be replaced by a new bush due to friction with the pipe for a long time, the whole bush must be replaced There was a problem of cost burden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the bush structure for a pipe guide according to an embodiment of the present invention includes a pipe guide bushing 5 for guiding the up and down movement of the pipe 5 by wrapping the outer peripheral surface of the pipe 5, The bushing comprises an inner tube 10 that lubricates the outer circumferential surface of the pipe 5 and functions as a lubricant and an outer tube 20 that closely surrounds the outer circumference of the inner tube 10. [

A hooking jaw 11 is provided at the lower end of the outer circumferential surface of the inner tubular body 10 and a lower end of the inner tubular body 20 corresponding to the hooking jaw 11 ) Are provided.

Here, the catching jaw 11 is formed over the entire outer periphery of the lower end of the outer peripheral surface of the inner tubular body 10, and the corresponding receiving jaw 21 is formed over the entire inner circumference of the lower end inner peripheral surface of the outer tubular body 20 have.

A portion where the outer peripheral surface of the inner tubular body 10 meets the engagement protuberance 11 has a sloped surface 12 and a portion where the outer peripheral surface of the outer tubular body 20 and the corresponding base 21 meet, (22) so that the inclined surfaces (12, 22) are in close contact with each other.

The upper end of the inner circumference of the inner tube 10 is provided with an upper inclined surface 13 for smooth entry of the pipe 5.

A lower end slope 14 is provided at the lower end of the inner circumferential surface of the inner tubular body 10 to facilitate the entry of the pipe 5. [

The inner tube 10 may be made of a copper material and the outer tube 20 may be made of a steel material.

In the process of inserting the inner tube 10 into the outer tube 20, it is possible to apply cold filling.

The inner tube 10 having a tubular structure is firstly provided, and the outer peripheral surface of the lower end of the tubular body 10 is formed with the engagement protrusion 11 and the inclined surface 12 And the upper and lower inclined surfaces 13 and 14 for smooth entry of the pipe 5 are formed on the inner circumferential surface of the upper and lower ends thereof.

The inner peripheral surface of the lower end of the outer tube 20 corresponding to the inner tube 20 has a receiving step 21 and a sloping surface 22 corresponding to the engaging step 11 and the inclined surface 12.

In this state, the inner tubular body 10 is pressed downward through the upper end of the outer tubular body 20 to complete the insertion of the inner tubular body 10.

At this time, the inserting operation of the inner tube 10 is performed by applying cold stamping to each other so as to securely engage with each other.
