Description

  The present invention relates to an electric wire laying device, and more particularly, to a gripper type electric wire laying device installed with a thin, thin and small structure in a place where the accessibility of an operator is inferior, such as a cable tray of a ship.

  Usually, laying wires covered with a multi-core structure is an operation that requires a large number of personnel, but the efficiency has been increasing more and more with the introduction of various laying automation devices. However, the work of laying wires on cable trays installed in narrow spaces like ships and offshore plants still relies on manual work, requires a large number of personnel, and is prone to induce musculoskeletal diseases. This is a fact of low efficiency.

  The electric wire laying device mainly uses an electric / engine / pneumatic winch laying machine, a roller, an endless track, a ball-shaped roller and feeder, and a robot for pulling a guide rope. However, since these devices are heavy and large in size, they are mainly suitable for linear electric circuits. For this reason, it is a situation that is difficult to apply to an electric circuit that has a narrow work space or is connected perpendicularly to a curve.

  In particular, in the case of ships and plants, many electric circuits have many curves and vertical sections, and a new form of cable laying system is required. An apparatus used in such a system requires characteristics of small size, light weight, high speed, and high output.

  Techniques related to this are disclosed in the following patent documents.

  However, according to the following Patent Document 1, since the total length including the pulling portion becomes long, it is difficult to install in a narrow space. Further, according to the following Patent Document 2, since the structure is complicated, there is a great risk of being inferior in reliability and durability.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows a system for laying an electric wire 150 on an electric circuit having a plurality of trays 110, 120, and 130. The electrical path includes a horizontal tray 110, a vertical tray 120, and a corner tray 130. In ships and plants, the electric circuit is narrow or formed in a long length including a large number of straight lines and curves. The curved electrical path is configured at a number of points, including the corner tray 130.

  A gripping means 300 is disposed on the electric path. The gripping unit 300 automatically performs gripping and release of gripping when the driving unit 400 described later reciprocates. The gripping means 300 facilitates installation on a narrow electric circuit. Moreover, in the conventional winch laying machine, it is mainly used when laying a thick power line in a straight electric circuit. When a cable is installed in a very long electric circuit, a roller or the like is mainly used for the purpose of reducing the friction between the cable and the electric circuit. However, the electric wire 150 is still damaged because the electric wire 150 is applied with a very large tension. Probability is high.

  In particular, when a curved circuit and a straight circuit are mixed, a very large force is applied to the curved circuit itself, so there is a high risk of breakage. Use is limited.

  The gripping means 300 uses a combination selected from a car-shaped gripper 331, a U-shaped gripper 333, and a balloon-shaped gripper 335. The car-type gripper 331 interrupts the movement of the electric wire 150 by the rotation of the arm, the U-shaped gripper 333 interrupts the movement of the electric wire 150 by the ascent and descent of the U-shaped band, and the balloon-type gripper 335 The movement of the electric wire 150 is interrupted by inducing expansion and contraction of the band by air pressure. The car-type gripper 331, the U-shaped gripper 333, and the balloon-type gripper 335 can be reduced in size, and can be easily installed on the narrow trays 110, 120, and 130.

  On the other hand, as shown in FIG. 6, the small car gripper 331, U-shaped gripper 333, and balloon gripper 335 are tightly supported on the top and bottom surfaces of the trays 110, 120, and 130 using the respective clamps 227. Can be installed.

  In addition, driving means 400 that draws the electric wire 150 by reciprocating movement of the actuator is disposed at many points on the electric circuit so as to cooperate with the gripping means 300. Since the gripping means 300 has a structure arranged in the middle of the trays 110, 120, and 130, the tension applied to the electric wire 150 is not large, and the drive means 400 can be downsized. When the tension of the electric wire 150 is large, it is possible to cooperate the driving device 400 with a conventional device such as a winch, a puller, or a feeder.

  The driving means 400 adjusts the operation timing between the actuators by a switch 410, an adjustment valve 412, and a time delay valve 415. As the driving means 400, a pneumatic reciprocating actuator is suitable, but a hydraulic cylinder, an electric type, an engine type, or the like can also be used. Such an actuator is operated by a configuration having a switch 410, an adjustment valve 412, and a time delay valve 415 as shown in FIG. The switch 410 uses a lever that is manually operated by an operator, the adjustment valve 412 performs functions such as start, stop, and reset, and the time delay valve 415 is provided between the equipment including the gripping means 300 and the driving means 400. Set the difference between start and stop time. It is also possible to use an electric circuit in combination with the pneumatic circuit as shown in FIG.

  Further, the control unit 500 controls the gripping unit 300 and the driving unit 400 in a distributed manner in the unit controller 510 and the central controller 520. The unit controller 510 is installed in the setting area of the trays 110, 120, and 130, and the central controller 520 is connected to the plurality of unit controllers 510 at a position where operation is easy. A wireless controller 530 may be interposed between the unit controller 510 and the central controller 520.

  FIG. 8 shows an apparatus for laying the electric wire 150 on the set path by applying a laying force. In the case of a ship, the cable tray 100 that supports the electric wire 150 is narrow, complex, and arranged in a horizontal, vertical, and curved shape at a high position. The electric wire laying device 160 of the present invention is intended for shipboards and marine plant cable trays 100 having a poor installation environment, but is not limited thereto.

  The electric wire laying device 160 of the present invention has a moving body 210, a gripping means 300, and a driving means 400 as main components. Below, it demonstrates centering on such main structures, and adds the detailed structure regarding this.

  The moving body 210 according to the present invention includes a link 220 that can move in the forward and backward direction of the electric wire 150. The moving body 210 is based on a frame for fixing to the cable tray 100, and accommodates the link 220 on the frame so as to be able to move forward and backward. The 'backward and forward movement' means a direction in which the electric wire 150 is laid, and thus includes all horizontal, vertical, and curved directions that are paths of the cable tray 100. The forward / backward movement of the link 220 is not limited to linear movement but includes rotation.

  The link 220 in the moving body 210 moves together with the electric wire 150 only when moving in one direction. Accordingly, the link 220 can move together with the electric wire by the action of frictional force during the forward movement, and can move backward separately from the electric wire during the backward movement. Such a one-way laying force is performed by a simple mechanical mechanism, as will be described later, thus simplifying the overall configuration.

  Here, the hinge shaft 223 for connecting the moving body 210 and the link 220 is detachably provided with at least one of a split pin, a snap ring, a screw, and a key. The moving body 210 and the link 220 are provided with a stopper 225 to limit the forward / backward movement range.

  Further, the gripping means 300 has a gripper 310 that grips the electric wire 150 in cooperation with the link 220. The gripper 310 interrupts the laying force on the electric wire 150 together with the link 220 described above. Normally, one gripper 310 is applied to one link 220, but a plurality of grippers 310 may be applied.

  The gripper 310 of the gripping means 300 uses at least one of a wire rod, a belt, a U-shaped bar, and a one-way roller. The wire can be bent flexibly, and is advantageous in terms of attachment / detachment (load / unload) of the electric wire 150. The belt has flexibility such as a wire, has a relatively wide width, and may include unevenness on the inner surface depending on the case. The U-shaped bar is inconvenient for attaching and detaching the electric wire 150, but has high strength and can improve durability. In addition, the one-way roller has a structure in which a roller and a one-way clutch are coupled, and is disadvantageous in terms of light, thin and small side surfaces, but can minimize the frictional force during reverse travel. The wire rod, belt, U-bar and one-way roller of the gripper 310 can be used alone or in combination.

  Here, when the gripper 310 is a wire, at least one of a wire rope, a chain, a fiber, and a resin can be used. The wire rope is preferably steel, but may be fiber or resin. The chain is disadvantageous in lightness, smallness, and smallness, but it is easy to replace parts at the time of cutting. The fiber and the resin can be used as a single core or a coaxial shape having high strength.

  Meanwhile, it is desirable that the gripper 310 further includes at least one of a plurality of blocks, spirals, and meshing irregularities so as to correspond to the diameter of the electric wire 150. When a configuration for adjusting the length is added to the gripper 310, the gripper 310 can be used as it is even if the diameter of the electric wire 150 changes. As the block, it is desirable to use a sphere, a polyhedron, a cone or the like formed of a metal material, but a nut which is a standard product can be replaced at least partially. In any case, the block is coupled to a certain section of the wire, and is coupled to the link 220 by opening a gap at a desired point. In addition, the length of the gripper 310 can be adjusted by a method in which a part of the regions is coupled with a spiral, or the projections and recesses are meshed and pressed on one side with a screw.

  Further, the gripping means 300 includes a lock body 315 for attaching and detaching the gripper 310, and the lock body 315 uses at least one of a pocket, a bracket, and a screw. One end of the gripper 310 is firmly fixed to the link 220, and the other end is fixed to the lock body 315 so as to be disassembled. When a wire rod is used for the gripper 310 and a plurality of blocks are coupled to the wire rod, the link 220 is formed with a pocket that can be engaged with the block. Similarly, a bracket or a screw can be used as the lock body 315 by the gripper 310 and its length adjustment method.

  The gripper 310 of the gripping means 300 further includes a covering material 313 made of at least one of an air hose, vinyl, leather, fiber, and rubber in order to prevent the electric wire 150 from being damaged. When the pressing force of the gripper 310 coupled to the link 220 acts on the electric wire 150, there is a high possibility that the coating of the electric wire 150 is damaged by a high load. In order to prevent this, a coating material 313 having a high friction system number and wear resistance is added to the outer surface of the gripper 310. As the covering material 313, at least one of an air hose, vinyl, leather, fiber, and rubber, which is a resin material, is used. Further, when there is no possibility of damage to the electric wire 150, the covering material 313 may not be used.

  Further, the driving means 400 according to the present invention induces the movement of the link 220 and the gripper 310 to apply a laying force to the electric wire 150. The forward and backward movement of the link 220 and the gripper 310 on the moving body 210 is performed by the driving means 400. As described above, the laying force acts on the electric wire 150 only when the driving unit 400 moves in one direction.

  The control means 500 of the present invention is applied with different circuit configurations depending on the hydraulic / pneumatic method and the electric method.

  In operation, FIG. 10 shows a state in which the link 220 moves forward and tilts backward together with the gripper 310 to maximize the sliding friction force and to apply the laying force to the electric wire 150. FIG. While moving backward, it tilts forward together with the gripper 310, the sliding frictional force is lost, and the electric wire 150 is positioned as it is. The forward and backward inclination of the link 220 is caused by the angle limitation of the stopper 225 described above. The direction in which the laying force is applied when moving forward and backward can also be changed depending on the installation direction of the moving body 210 and the gripping means 300.

  FIG. 12 shows a device for laying the electric wire 150, particularly a gripper type device. When a gripper type device is used, the electric wire 150 can be easily laid on a narrow space electric circuit such as a cable tray of a ship. Although the electric wire 150 is intended for large-diameter and heavy thick wires, it is not limited thereto.

  In the following description, “front”, “front”, “forward”, “back”, “rear”, and “reverse” are based on the direction in which the electric wire is attracted and moved.

  The present invention includes a base 211 having a hinge shaft 223. The base 211 supports a link 220 described later, and is fixed to an actuator (not shown) with a bolt. The hinge shaft 223 for binding the link 220 to the base 211 is provided with a structure that can be easily separated using a snap pin.

  In addition, a link 220 having a wire rope 320 is rotatably provided on the hinge shaft 223 of the base 211 in order to bind the electric wires 150. The link 220 has a semicircular structure whose upper side is open, and is coupled to the hinge shaft 223 of the base 211 on the lower side. The wire rope 320 uses a steel material or a fiber material, and has a coating in a certain section in order to increase the frictional force with the electric wire 150.

  The base 211 includes a stopper 225 that limits the range of motion of the link 220. The stopper 225 is formed as a groove or a protrusion in a portion close to the link 220 in the base 211. The stopper 225 guides the link 220 so as to rotate within a certain angle in the front-rear direction around the vertical line in the process of laying the electric wire.

  The wire rope 320 of the link 220 includes a plurality of spheres 321 that adjust the binding length. The spherical body 321 is connected to a certain section of the wire rope 320 with a slight gap. The gap between the spheres 321 is to be inserted into a cut-out portion on one side of the link 220 and bound. The diameter of the sphere 321 determines the bundling length (diameter) of the wire rope 320 corresponding to the change in the thickness of the electric wire 150.

  The link 220 includes a ball plunger 323 that supports the wire rope 320. The ball plunger 323 is composed of a ball and a spring accommodated in the groove of the link 220 and restrains the temporary detachment of the wire rope 320 by an elastic force acting on the ball. The ball of the ball plunger 323 does not need to be a sphere as a whole, and may be formed so as to have a hemisphere in part.

  Further, the link 220 includes a friction shoe 325 that applies a sliding resistance force in one direction against the electric wire 150. The friction shoe 325 may be coupled to one surface of the link 220 to apply a frictional resistance to the coating of the electric wire 150.

  FIG. 13 is a modification of FIG. 12 and shows an engagement mechanism for attaching and detaching the electric wire of the electric wire laying gripper. Since the gripper type electric wire laying device can be realized with a light, thin and short structure, it is narrow and wide and vertically arranged in a horizontal, vertical, curved shape like a ship's cable tray. It is suitable for. The gripper applies a frictional force in one direction and pulls the gripper forward and backward in the moving direction of the electric wire.

  The base 211 according to the present invention is coupled to an hydraulic / pneumatic cylinder (not shown) to perform forward / backward movement and provide a pulling force against the electric wire.

  A link 220 is provided on the base 211 via a hinge shaft 223. The link 220 is formed with a semicircular cross section for supporting the lower side of the electric wire. The link 220 is connected to the base 211 via a hinge shaft 223 and rotates forward and backward within a set angle range. The link 220 is set such that the rearward inclination angle at the moment of pulling the electric wire in the forward movement is larger than the forward inclination angle at the moment of sliding the electric wire in the backward movement.

  The link 220 includes a fixing groove 231 and a ball pocket 235 to support the wire rope 320. The fixing groove 231 supports one end of the wire rope 320 tightly, and the ball pocket 235 supports the other end of the wire rope 320 in a detachable manner. A fastening groove 233 is formed around the fixing groove 231 and the split pins 318 are coupled to prevent the wire rope 320 from being temporarily detached. The ball pocket 235 is formed in a hemispherical shape so as to tightly accommodate one of the spheres 321 of the wire rope 320. As a result, the wire rope 320 maintains a tightly coupled state with the ball pocket 235 while the link 220 moves forward while being inclined backward.

  The fixing groove 231 and the ball pocket 235 are provided with respective side grooves 232 for the wire rope 320 to enter and exit. The side groove 232 is a groove that is formed in a direction orthogonal to the front and rear and allows the wire rope 320 to pass therethrough. The fixed groove 231 and the lateral groove 232 communicate with each other on one side of the link 220, and the ball pocket 235 and the lateral groove 232 communicate with each other on the other side. Since the wire rope 320 hooks into the ball pocket 235 via the lateral groove 232, the mounting is quick. However, since the wire rope 320 may be detached while being opened by the elastic force, the fastening groove 233 and the division pin described above may be provided.

  The side groove 232 communicating with the ball pocket 235 provides a champ or round at the entrance. This allows the sphere 321 to enter quickly via a champ or a round when the wire rope 320 is attached to the link 220. Champas and rounds are all formed at the part that contacts while the sphere 321 passes. Further, it is desirable to form the champ 238 so that the sphere 321 is seated on the upper surface of the link 220.

  In use, with the other end of the wire rope 320 disassembled, the electric wire is placed on the link 220, the gap between the spheres 321 is opened at the other end of the wire rope 320, and the side groove 232 at the other end of the link 220 is opened. When sandwiched, the lower sphere 321 is seated on the lower ball pocket 235 and the upper sphere 321 is seated on the champ 238. Thereafter, when the base 211 is operated to induce the forward / backward movement of the link 220, the electric wire is drawn in one direction and laid by the cooperation of the wire rope 320, the link 220, and the friction shoe 325.

  FIG. 14 is another modification of FIGS. 12 and 13, and is in the category of identity in the main configuration including the link 220, the fixing groove 231, and the ball pocket 235.

  The fixing groove 231 and the ball pocket 235 include a side groove 232 and an L-shaped groove 236 for entering and exiting the wire rope 320, respectively. The side groove 232 is a groove that is formed in a direction orthogonal to the front and rear and allows the wire rope 320 to pass therethrough. The L-shaped groove 236 has a passage bent in two directions, that is, the front-rear direction and the side direction. The fixed groove 231 and the side groove 232 communicate with each other on one side of the link 220, and the ball pocket 235 and the L-shaped groove 236 communicate with each other on the other side. Since the wire rope 320 reaches the ball pocket 235 via the L-shaped groove 236, a tightly coupled state is maintained after mounting. That is, since the L-shaped groove 236 restrains the opening of the wire rope 320 by the elastic force, the dividing pin 318 is not required.

  Here, the L-shaped groove 236 maintains the angle of the intersecting passage in the range of 70 to 110 °. The front and rear passages and the side passages of the L-shaped groove 236 may cross each other so as to maintain a right angle, but may intersect at an acute angle or an obtuse angle within a set range. When the crossing angle is less than or equal to the appropriate value, it is not easy to attach the wire rope 320.

  16 to 18, the tray clamp 180 includes a main body 200 having a certain length and width, a clamp 227 formed to protrude from one end of an upper end and a lower portion of the main body 200, and a gripper in the middle of the main body 200. Includes a mounting portion 218 on which the main body 200 is mounted and a fixing means 250 for fixing the main body 200 to a cable tray.

  The main body 200 of the tray clamp 180 is configured as a rectangle having a certain length and width. The length of the main body 200 is longer than the distance between the cable trays.

  Moreover, the auxiliary tool 480 is rotatably fixed to the upper end and the lower end of the main body 200, respectively. Such an auxiliary tool 480 not only protects the electric wire by bending the electric wire more loosely when laying the electric wire at the portion where the cable tray is inclined or bent, but also makes the electric wire move more smoothly in the bent section. .

  The main body 200 is formed with a long hole 213 in which the fixing means 250 is mounted at the upper part and the lower part, respectively. The long hole 213 makes the mounting of the fixing means 250 easy by changing the position of the fixing means 250 and being seated on the cable tray. The long hole 213 is provided with a lid 214 that prevents the fixing means 250 from being exposed to the outside.

  The main body 200 is formed with a plurality of fixing holes 215 on both the left and right sides in the length direction. In these fixing holes 215, a reinforcing material 216 having a certain length is fixed.

  That is, the reinforcing material 216 reinforces the strength of the main body 200, thereby preventing deformation and damage of the main body 200 due to the electric wire laying operation.

  A clamp 227 protrudes from the main body 200 so as to be seated on the cable tray. The clamps 227 are formed at the upper end and the lower portion of the main body 200 and project from the both side surfaces of the main body 200 with a certain length.

  The clamp 227 is formed with a plurality of terminal rods 228 so as to be seated regardless of the shape and size of the cable tray. The terminal rod 228 is formed in a step shape from the end of the clamp 227 toward the main body 200.

  A mounting portion 218 is formed on the main body 200. The mounting portion 218 stably mounts a gripper (not shown) at an intermediate position of the main body 200. That is, the mounting part 218 forms a plurality of holes at regular intervals so that the gripper is mounted on the main body 200.
