That is, the frame-side driven gear 300 may be rotated by receiving the rotational force transmitted from the drive gear 200.

An operating bar 400 is installed at an upper end of the frame 100, and the operating bar 400 is a long plate-shaped member, and a handle H is formed at one side thereof, and the operating bar 400 is operated according to the operation of the handle H. 400 is moved while pushing to the right in the drawing. More specifically, the fitting plate 410 is inserted into one side of the upper end of the frame 100 and a through hole is formed in the center of the fitting plate 410. In addition, a cylindrical auxiliary bar 430 coupled to one end of the operation bar 400 is disposed to have the female screw part 420 on the left side of the through hole in the drawing so as to pass through the through hole. In particular, the auxiliary bar 430 is partially formed with a male screw to be coupled to the female screw portion 420 and to couple the handle (H) to the auxiliary bar 430. As the handle H is operated, the operation bar 400 is moved to the right. Accordingly, the rotation bracket 500 to be described later may be changed to be in a vertical state or inclined inclinedly.

That is, the operation bar 400 is sufficient to be able to move left and right as needed, and as shown in the present embodiment to be moved to the right side in the drawing by the handle (H) operation, and to return the handle (H) After turning to the original position will be able to push the operation bar 400 to the left by hand. However, the operation bar 400 may be configured to move left and right at the same time according to the handle (H) operation.

The operating bar 400 is provided with the number of rotation brackets 500 of the number of frame-side driven gear 300, in this embodiment it is to have four rotation brackets (500). The rotating bracket 500 has a pair of two, the upper end of the rotation bracket 500 is connected to the operation bar 400 and the lower end is in the shaft (sh) in which the frame-side driven gear 300 is inserted The connection is made. The operation bar 400 has a predetermined width, and thus, each of the rotation brackets 500 has two plate members spaced apart by the width of the operation bar and connected to the pin 530.

In order to allow the rotation bracket 500 to be rotated with respect to the frame-side driven gear 300, a rotation bracket 500 may be inserted into the shaft sh by drilling a hole in the lower end of the rotation bracket 500. So that they are combined together.

A bracket side driven gear 600 is disposed to be engaged with an upper side of the frame side driven gear 300. The bracket side driven gear 600 is rotatably connected between the pivoting brackets 500. Use (sh). Both ends of the shaft (sh) are inserted into the rotation bracket 500, the bracket side driven gear 600 is installed on the shaft (sh) via a means such as a bearing.

The bracket side driven gear 600 is also a structure that can be assembled and disassembled by a combination of the second gear 610, the second feeder 620 and the second fastening plate 630, the second gear 610 is a frame Rotation is made by engaging with the first gear 310 constituting the side driven gear 300 and the second feeder 620 is rotated in a state in which the steel wire to be supplied together with the first feeder 320 rotates up and down, Will be provided. The more detailed structure of the bracket-side driven gear 600 is the same as the frame-side driven gear already mentioned, and thus a detailed description thereof will be omitted.

When the hydraulic motor M installed in the frame 100 operates, the drive gear 200 connected to the rotary shaft S rotates, and the frame side driven gear 300 connected to the drive gear also rotates, and at the same time, the bracket side driven The gear 600 also rotates. In addition, the steel wire inserted into the steel wire groove wh may be transferred in the rotation direction due to the frictional force as the frame-side driven gear 300 and the bracket-side driven gear 600 are rotated.

The diameter of the steel wire to be transferred using the wire insertion device according to the present invention can be changed at any time, and thus it is necessary to configure to enable smooth use regardless of the wire diameter change.

That is, when the diameter of the steel wire is reduced, it is necessary to narrow the interval between the steel wire groove wh formed in the frame-side driven gear 300 and the bracket-side driven gear 600. In order to cope with this, the present invention allows the position of the bracket-side driven gear 600 connected to the operation bar 400 to be varied so that the distance between the wire grooves wh can be adjusted.

As shown in FIG. 10, when the operation bar 400 is moved to the right in the drawing by turning the handle H provided in the operation bar 400, the rotation bracket 500 is inclined to the right side. When the rotation bracket 500 is inclined, the bracket-side driven gear 600 engaged with the frame-side driven gear 300 is rotated to move to a slightly low position. Accordingly, the spacing between the wire grooves (wh) is narrowed and can provide an appropriate friction force to the steel wire.

In the present invention, since the frame-side driven gear 300 and the bracket-side driven gear 600 are rotated by the gear teeth, the power transmission can be surely performed, and also by adjusting the spacing of the steel wire groove wh according to the steel wire diameter. Optimal friction can be provided to prevent slippage of steel wires.

On the other hand, it is necessary to easily change the rotational direction of the hydraulic motor (M) because it is necessary to push or pull out the steel wire using this apparatus. To this end, it is preferable to place the adjustment lever 700 to adjust the rotational direction of the hydraulic motor (M) on one side of the frame 100. The connection between the adjustment lever 700 and the hydraulic motor (M) itself can be achieved by a known hydraulic technology, which will not be described in detail.

Preferably the hollow pipe (P) to protrude to the left and right sides of the frame 100, one side is to be an inlet for the steel wire is introduced and the other side is to be the discharge port discharged. The steel wire fed into the hollow pipe (P) enters between the steel wire groove (wh) provided in the frame-side driven gear 300 and the bracket-side driven gear 600, and the frame-side driven gear is rotated by the hydraulic motor (M). When the 300 and the bracket-side driven gear 600 is engaged and rotated, the steel wire is gradually transferred and exits through the hollow pipe in the discharge direction.

The wire inserting device according to the present invention has an advantage in that it can be smoothly transported while preventing slip in the steel wire because the ease of use is excellent and the rotational force is surely made.

In addition, even if the diameter of the steel wire changes, it can cope appropriately, and the moving direction of the steel wire can also be adjusted in the forward and reverse directions.

In addition, the frame-side driven gear and the bracket-side driven gear used in the steel wire insertion device can be continuously used by replacing only the feeder part where wear occurs by using a modular feeding assembly. It is expected technology.
