Description

{Simple feeder apparatus for installing fine cable bundle}

The present invention relates to a device for installing a bundle of thin wires, and more specifically, to a simple feeder device for installing a bundle of thin wires for installing a small diameter wire in a narrow space such as a ship.

The feeder currently used for cable installation is a large-sized one, usually placed on the deck of a ship, and a dedicated seat is installed to generate power and install it using air pressure. This makes it impossible to install it between power lines or in narrow spaces, and the target wire size is 50SQ (O.D: 35mm) or more, which corresponds to a large wire. Since there is no feeder that can install fine cables of 35mm or less, manual work is largely relied on, and the number of strands is limited to one for installation.

Therefore, equipment capable of simultaneously laying multiple strands of thin cable (O.D.: 35 mm or less) in narrow spaces such as between power lines is required.

In this regard, prior art documents that can be referenced include Korean Patent Publication No. 1664802 (prior art document 1) and Korean Patent Publication No. 1744639 (prior art document 2).

Prior art document 1 includes a gripper having a rotating body and a tightening band that are reciprocally connected to an actuator of a driving device and that holds a wire; and a pressure block that is arranged on one end of the gripper to induce forced rotation. Accordingly, it is expected that the gripper, which is compact and lightweight, can be used for work in narrow spaces and that 2 to 4 thin wires having similar diameters can be pulled and laid at the same time.

Prior art document 2 includes a pressurizing unit having a pressurizing roller on the upper side of the casing and applying a pressurizing force by contacting the upper surface of the fine wire; a transfer unit having a transfer roller inside the casing and generating a frictional force by contacting the fine wire; and a control unit providing a driving force set to the pressurizing unit and the transfer unit. Accordingly, it is expected that the effect of reducing safety accidents or musculoskeletal diseases by simultaneously laying a plurality of fine wires is achieved.

Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings.

The present invention proposes a simple feeder device for laying a bundle of thin wires on a power line. It is intended for a device for installing a small-diameter wire in a narrow space such as a ship, but is not necessarily limited thereto. The thin wire, which is the object of laying, refers to a power/communication/control cable with an outer diameter of 35 mm or less.

Referring to Figure 1, the device of the present invention is shown as being closely mounted on a circuit (10). The circuit (10) is a structure in which a plurality of rungs (13) are connected at regular intervals between opposing pipes (11).

The main body (20) according to the present invention has a structure having a guide plate (25) and a lock hook (26) on one side of the frame (21).

Referring to FIGS. 1 and 2, a frame (21), a guide plate (25), a lock hook (26), etc., which constitute a main body (20) are shown. The frame (21) is configured in a shape that is bent roughly in an "L" shape to maintain structural simplicity and rigidity. The guide plate (25) and the lock hook (26) are connected to an upper roller (31) of a roller member (30) described below and are required in the process of inserting a thin cable (15), which is an installation target.

According to the detailed configuration of the present invention, the main body (20) is characterized by having a clamp (22) that is horizontally fixed to a pipe (11) and a clamp (23) that is vertically fixed to a rung (13).

In FIG. 1 and FIG. 2, a clamp (22) on one side and a clamp (23) on the other side constituting the main body (20) are shown. The clamp (22) on one side of the frame (21) is configured by horizontally fastening a butterfly bolt to a curved block that is in close contact with a pipe (11) of an electric circuit (10). The clamp (23) on the other side of the frame (21) is configured by vertically fastening a butterfly bolt to a “ㄷ” shaped plate that is in close contact with a rung (13) of an electric circuit (10). When the main body (20) is configured with two-point support by horizontal and vertical clamps (22)(23), it is easy to quickly change the position on the electric circuit and work.

According to the detailed configuration of the present invention, the main body (20) is characterized in that it rotatably supports a C-shaped lock hook (26) on a guide plate (25) having a U-shaped groove, and interposes an elastic body (28) to control the rotation of the upper roller (31).

Referring to FIGS. 2 and 3, a guide plate (25), a lock hook (26), an elastic body (28), etc., which constitute a main body (20) are shown. The guide plate (25) has an approximately “U” shaped groove so as to be engaged with a lever (33) of an upper roller (31). The lock hook (26) is formed in an approximately “C” shape so as to engage or disengage the lever (33) in conjunction with the guide plate (25). The lock hook (26) has a hinge portion indicated by reference numeral 26a, a sliding portion indicated by reference numeral 26b, a biting portion indicated by reference numeral 26c, and a pressing portion indicated by reference numeral 26d. The hinge portion rotatably supports the lock hook (26) on the guide plate (25). The sliding portion is formed as a curved surface so that the lever (33) slides and descends. The biting portion is curved in the sliding portion so as to grip the lever (33) in conjunction with the guide plate (25). The pressing part protrudes in a cantilever shape at the top so that the worker can forcefully rotate the lock hook (26). An elastic body (28) in the form of a torsion spring is mounted on the hinge part. As shown in Fig. 3(a), the elastic body (28) causes the lock hook (26) to rotate in one direction, thereby keeping the lever (33) in a locked state. To release the lever (33) when the installation is completed, the pressing part is pressed as shown in Fig. 3(b) to rotate the lock hook (26) in the opposite direction.

In addition, according to the present invention, a roller member (30) having an upper roller (31) and a lower roller (35) on the frame (21) forms a structure in which the upper roller (31) is rotatably supported on the lower roller (35).

In FIGS. 1 and 2, an upper roller (31), a lever (33), a lower roller (35), etc., which constitute a roller member (30) are shown. The lower roller (35) is formed based on wear-resistant rubber, resin, or a composite thereof, and is rotatably supported at both ends of the frame (21). The upper roller (31) is formed based on rubber or resin, and is rotatably supported by interposing a hinge (32) at one end of the lower roller (35). The upper roller (31) also has a rotatable structure like the lower roller (35), but can be configured in a passive state that does not directly receive power. The lever (33) extending to one side of the upper roller (31) is preferably formed as a circular bar with a structure that can be folded in the middle, considering the narrow space of the electric circuit.

According to the detailed configuration of the present invention, the roller member (30) is characterized by having a plurality of auxiliary rollers (37) adjacent to the upper roller (31) and the lower roller (35) in the main body (20).

In Fig. 2, a plurality of auxiliary rollers (37) are shown adjacent to the upper roller (31) and the lower roller (35). In the installation state where the upper roller (31) and the lower roller (35) are closely opposed, two auxiliary rollers (37) are positioned forward and two auxiliary rollers (37) are positioned backward. The auxiliary rollers (37) are rotatably connected to the frame (21) through their respective holders (38), and the thin cable (15) is prevented from being biased or interfered with to the left or right of the opposing rollers (31) (35) during the installation process.

In addition, according to the present invention, the movable member (40) assists the functions of the main body (20) and the roller member (30) and has a structure that applies laying power to the roller member (30).

In Fig. 1, the movable member (40) basically applies power to the lower roller (35) by means of a driving motor (41) and a reducer (43). The driving motor (41) and the reducer (43) are mounted on the frame (21) and connected to the driving shaft of the lower roller (35) on one side. The movable member (40) is connected to the main body (20) and the roller member (30) to assist in the function during the laying process. The movable member (40) assists in the work before and after laying and also assists in the response according to the thickness of the fine cable (15).

According to the detailed configuration of the present invention, the movable member (40) is characterized by having an adjustment rod (45) connected to induce up-and-down movement of the lock hook (26), an adjustment nut (46) fastened to the adjustment rod (45) to induce height change of the lock hook (26), and an elastic body (48) mounted on the adjustment rod (45) to apply elastic force to the lock hook (26).

In FIGS. 2 and 3, a control rod (45), a control nut (46), an elastic body (48), etc., which constitute a movable member (40) are shown. The control rod (45) is vertically supported on one side of the frame (21) so as to be able to move up and down. It is preferable that the upper end of the control rod (45) be connected to the hinge portion (26a) of the lock hook (26). An elastic body (48) and an adjustment nut (46) are sequentially and concentrically mounted on the lower area of the control rod (45). When the control nut (46) is tightened, the elastic body (48) contracts and at the same time, the lock hook (26) is lowered, thereby increasing the force with which the upper roller (31) presses the fine cable (15). Conversely, when the elastic body (48) is loosened, the upper roller (31) rises, thereby reducing the force with which the fine cable (15) is pressed. The tightening state of the adjusting nut (46) can be changed by considering the standard (thickness) of the thin cable (15) and the wear state of the roller (31) (35).

Referring to Fig. 4, an example of a laying operation is schematically explained. As in Fig. 4(a), after fixing a simple feeder device to a circuit (10), the lever (33) is raised to rotate the upper roller (31) upward. As in Fig. 4(b) and Fig. 3(a), the thin cable (15), which is an object to be laid, is hung on the lower roller (35), and then the lever (33) is lowered, so that the cable slides along the slide portion (26b) of the lock hook (26) and is interlocked with the guide plate (25), thereby maintaining an interlocked state. As in Fig. 4(c), when power is applied to the drive motor (41), the lower roller (35) rotates and moves the thin cable (15) onto the circuit (10) in conjunction with the upper roller (31), thereby performing laying.

The present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should fall within the scope of the claims of the present invention.
