[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe small-scale repair machine, and more specifically, it is a product made of a circular pipe as a main shaft among temporary steel equipment used for construction and civil engineering, that is, a single pipe used as a steel pipe scaffold. It is used for repairing.

[0002]

[Prior art]

 Conventionally, this kind of thing is as follows. In many cases, an appropriate number of single pipes are connected and used, and if the small end is deformed, the joint material (single pipe joint, connecting pin, etc.) used for the connection may not fit. The causes of deformation and crushing of the edge are as follows. 1. In the case of drop during assembly or disassembly, 1. In the case of a shock (collision) during work, In transit, 4. When trampled by heavy machinery. As a result, the product value is lost, the aesthetic appearance is deteriorated, and it takes time to repair. Are causing problems. Therefore, the repair is done as follows. 1. Hit it with a hammer to fix it. 2. Insert the tapered rod-shaped metal fitting and hit it with a hammer to correct it. 3. It is repaired using a hydraulic mechanical jig (slide cotter type) (no mobility).

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. 1. The hammer striking method is not efficient for anyone, and it is not efficient because it does not work in a short time. 2. The method of using a hydraulic mechanical jig is not convenient for anyone to use, and it is inconvenient to move because it is a heavy object, and it requires a combined facility such as power.

The present application has been made in view of such problems of the conventional art, and an object of the present application is to provide the following. It is easy to move and can be used for anyone to make small repairs. It can also be used for packaging, transportation, work in high places, etc.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the case of the present application, the repair machine body 5 attached to the tips of the left and right levers 2 and 3 configured to be openable and closable around the first pin 4 provided near the tip portion is the left and right repair machine unit 5A. , 5B, and the repair machine unit 5A on the left side is composed of a semi-cylindrical material with a curved surface 5A1 facing leftward, and the repair machine unit 5B on the right side has a curved surface 5B1 facing to the right. It is made up of a semi-cylindrical shaped cross-section material that has been positioned, and the tips of these left and right repair machines 5A and 5B are openably and closably connected by a second pin 5C parallel to the first pin 4, This is a pipe edge repair machine configured such that the left and right repair tool units 5A and 5B are closed and opened around the second pin 5C in response to opening and closing of the left and right levers 2 and 3. In this case, the repair machine unit 5A on the left side has a curved surface 5A1 directed to the left side, and the repair machine unit 5B on the right side has a curved surface 5B1 directed to the right side. It can be formed in a tapered shape that becomes thinner.

[0006]

【Example】

 Examples will be described with reference to the drawings. 1 is a pipe edge repair machine of the present invention. Reference numerals 2 and 3 denote left and right levers, which are formed with inward projections 2A and 3A having a substantially semicircular shape in plan view and outward projections 2B and 3B at the tips, and at the centers of these inward projections and outward projections. The vertical holes 2A1, 3A1, 2B1, 3B1 are opened in parallel with each other, and the vertical holes 2A1, 3A1 in the inward projections 2A, 3A are connected by a first pin 4. Therefore, the left and right levers are configured to be openable and closable around the first pin 4.

Further, in the vicinity of the tips inside the left and right levers 2 and 3, left and right protrusions 2A2 and 3A2 having a semicircular planar shape are provided so as to face inward. Therefore, when the left and right levers are closed inward, the left and right protrusions 2A2, 3A2 come into contact with each other, and the outer protrusions 2B, 3B of the left and right levers around the first pin 4 are slightly opened outward. Become.

Reference numeral 5 denotes a repair machine body attached to the tips of the left and right levers. The repair machine body is composed of left and right repair machine bodies 5A and 5B, and the left repair machine body 5A has a curved surface 5A1 directed to the left. The repair machine unit 5B on the right side is formed of a substantially semi-cylindrical section material with the curved surface 5B1 facing to the right. The tips of the repair machines 5A and 5B are openably and closably connected by a second pin 5C parallel to the first pin 4, and the rear end of the repair machine 5A on the left is an outer protrusion of the left lever 2. 2B1 is connected to the vertical hole 2B1 by the left pin 6 parallel to the first pin 4, and the rear end portion of the right repair machine unit 5B is connected to the vertical hole 3B1 in the outer protrusion 3B of the right lever 3 and the first hole 3B1. They are connected by a right pin 7 parallel to the pin 4. In this case, the repair machine unit 5A on the left side has a curved surface 5A1 directed to the left side, and the repair machine unit 5B on the right side has a curved surface 5B1 directed to the right side. It has a tapered shape that becomes thinner.

The present invention operates as follows. The pipe edge repair machine of the present application has a mechanism for expanding the left and right levers 2 and 3 simultaneously in the directions a and b at the same time in the directions c and d via the first pin 4 as shown in FIG. Become. The left pin 6 and the right pin 7 are power points for simultaneously inflating the left and right repair machine units 5A and 5B in the directions C and D at the same time. The second pin 5C serves as a fulcrum for the left pin 6 and the right pin 7.

The repair device single unit 5A on the left swells outward (in the direction of the arrow C) by the action of a and b with the second pin 5C as a fulcrum, and the repair device unit 5B on the right fixes the second pin 5C. As a fulcrum, it will swell in the outward direction (direction of arrow D) due to the action of a and b. The second pin 5C serves as a fulcrum for the left and right repair machines 5A and 5B. The first pin 4 is a central fulcrum of the pipe edge repair machine of the present application, and also serves as a fulcrum for transmitting the acting force to the other second pin 5C, the left pin 6, and the right pin 7.

The left pin 6 serves as a force point for moving the left repair machine unit 5A in the direction of C with the second pin 5C as a fulcrum, and the right pin 7 uses the second pin 5C as a fulcrum to move the right repair machine unit 5B. It becomes the point of force to move in the two directions. By manually operating the left and right levers 2 and 3 in the directions of e and f, the left and right repair machines 5A and 5B are returned to the positions shown in FIG.

Therefore, the left and right levers 2 and 3 are opened outward, that is, the left and right repair machine units 5A and 5B are closed, and the left and right repair machine units are deformed or crushed. If the left and right levers 2 and 3 are closed inward after inserting into the small edge portion 8A of the broken pipe 8, the left and right repair machines will be open outward, and this small edge will be corrected and repaired. be able to.

[0013]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. 1. Small edge deformation (crush) of a single pipe can be easily corrected. 2. It can be used for any material regardless of the inner diameter of the single pipe. 3. Anyone can easily operate it by human power. 4. Since it can be easily moved, it can be used for repairs even when working in high places or in the packed or transported condition.
