Definitions

  • the present invention relates to a stationary machine for coiling a cable inside a tank.
  • Electric cables manufactured and delivered in very long length in one piece cannot be wound on coils because the dimensions of these would become exorbitant. They are therefore stored in storage tanks by an operation called coiling.
  • This torsion is more or less well supported by the internal constitution of the cable, so that one endeavors to reduce it on the one hand and to distribute it on the other hand.
  • the mean diameter of the turns is increased.
  • we raise the altitude of the starting point of the twist which is generally the exit point of a pulley or a chute with or without hawser, delivering the cable in the vertical axis of the tank.
  • a machine for assisting in the coiling of a cable inside a tank the cable being distributed vertically in the center of the tank having an external wall defining a coiling area, the machine comprising a support rotating around an axis located in the axis of the tank and supporting a cable guide means.
  • the cable guide means consists of several pulleys adjustable in spacing.
  • This machine has drawbacks such as the use of a small number of pulleys which imposes heavy bending stresses on a heavy cable or even collapse between two successive support points, and the obligation to use this machine coiling in coiling because of the permanent presence on the ground, in the center of the tank, of the structure of the machine which hinders the natural coiling of the cable.
  • the object of the present invention is to remedy these drawbacks by proposing a semi-automatic machine providing the cable with a path with numerous support points on a deformable structure enabling the cable to be distributed over turns whose diameter can vary in a ratio of 1 to 3. and allowing the retraction of a cable guide bracket to release the cable at the hatch and thus achieve the natural unwinding of the cable.
  • the machine of the present invention is characterized in that the rotating support consists of a bracket rotating around a bearing placed vertically on the axis of the tank, and in that the guide means comprises a coiling arm oblique attached to the bracket and rolling on the outer wall of the tank, a carriage sliding along the coiling arm to distribute the cable in the coiling area, and a cable guide bracket, the cable passing successively through the cable guide bracket and in the cart.
  • the cable guide bracket is retracted during unwinding and the carriage has at its end on the tank side, a distribution curve.
  • the cable is guided from its exit from a chute to the distribution curve, between four multiple roller paths forming a parallelepiped cage.
  • FIG. 1 there is shown a circular tank 1 having a central portion 2 slightly conical to promote the unwinding of a cable, and an outer portion 3 in the form of a crown on which a drive device 11 is supported.
  • This drive device is provided with a motor 12.
  • the coiling arm 20 is hooked at its upper part to a bracket 70 which rotates around a bearing 90 placed at the vertical to the central axis of the tank by means of a bearing 91.
  • This coiling arm comprises a carriage 30 and a cable guide bracket 60.
  • a cable 4 therefore passes through the bearing 90, then in a chute 80, passes through the retractable cable guide bracket 60, then the carriage 30, leaves the carriage by a distribution curve 31 and finally falls vertically into the tank for form turns.
  • the carriage 30 is moved back and forth which distributes the cable vertically from the point of formation of the turn.
  • the position of the carriage 30 corresponds to the position of formation of the largest turn and the position 30a corresponds to the formation of the smallest turn.
  • Figure 4 shows in more detail the coiling machine mounted on the tank 1 composed of its central part 2 and its outer wall 3. This outer wall has a path 5, allowing an operator to monitor the machine, protected by a barrier 3 '.
  • an operator has platforms 100, 102, 104 and ladders 101, 103, installed on the coiling arm 20, or on the jib 70, all of the platforms and scales rotating with the machine.
  • the coiling arm 20 supports the carriage 30 driven by two chains 24 (24 'not shown) stretched between two pairs of toothed wheels 23 (23' not shown) and 22 (22 'not shown), 22 and 22' being toothed wheels drive wheels driven by a motor 21. Between the two chains 24, 24 ′ and over a certain length, rollers are mounted 25.
  • This carriage 30 also includes horizontal rollers 41 and vertical rollers 42 for guiding the cable. This moving carriage takes an extreme position 30a, which is the formation position of the smallest turn.
  • the end on the tank side of the carriage 30 has a distribution curve 31 making it possible to bring the cable 4 vertically and close to the wall 3 of the tank.
  • the cable guide bracket 60 also includes horizontal rollers 62, 62 'for cable guide and perpendicular rollers 61 (61' not shown) to the previous ones to form a closed cable guide cage. This parallelepiped cage is made over the entire length of the cable guide bracket.
  • the operator has at his disposal a control box 6 supported by a cable 7 fixed to a small hoist 8 which moves on a rail 9, radially to the tank.
  • This rail 9 is obviously liftable (position 9a) by a jack 8 ', so as not to hinder the cable during the unwinding operation.
  • Figure 5 shows the lower end of the coiling arm 20.
  • the carriage 30 is driven by two chains 24 (24 'not shown) rotating on two pulleys 23 (23' not shown). These pulleys are mounted on a spring device 26 which permanently tends these two chains.
  • the carriage 30 carries at its end the distribution curve 31 provided with horizontal rollers 33, vertical rollers 32 supported at their two ends and small rollers 35 supported at one end. All these rollers guide the cable as it leaves the carriage and give it a curvature in the vertical direction and a curvature in the circumferential direction, better visible in FIG. 2.
  • Figure 6 shows more precisely the upper part of the coiling machine where we see the cable guide bracket 60, provided with its rollers 61, 62, 62 '(61' not shown) and a basket 63, articulated along the axis 64 and operated by the jack 65.
  • the release position 60a is shown in broken lines.
  • the bracket 70 is connected to the coiling arm 20 by an articulation 71 which makes it possible to absorb the defects of concentricity or flatness of the external wall 3 of the tank 1 because this bracket 70 and this coiling arm 20 rotate together but according to different guides , the bracket around the bearing 91 (FIG. 1) and the arm 20 resting on a circular crown.
  • the coiling arm 20 supports the carriage 30 which rolls in two guide rails 54 (54 'not shown) by means of rollers 55 (55' not shown).
  • the cable is therefore trapped between the rollers 41, 42, 42 '(not shown) and the rollers 25 mounted between the chains 24, 24' (not shown), thus forming a parallelepiped cage over most of the length of the carriage.
  • Figure 7 shows more clearly the arrangement of all the carriage guiding devices and the different drives.
  • the motor 21 having an output shaft 27, and driving through a chain 28 a shaft 29 on which is mounted the two toothed wheels 22, 22 '.
  • a casing 21 ' hides the chain 28.
  • the coiling arm 20 consists of metal beams 57, 57 ', 58, 58', 59.
  • the shaft 29 is mounted on bearings 49,49 ′ integral with the beams of the coiling arm.
  • These two chains are guided in upper angles 51, 51 'and in lower angles 53, 53', part of which is the guide rail 54, 54 'of the carriage 30.
  • This carriage 30 is guided in the rails 54, 54' by rollers 55, 55 '.
  • the two chains drive the rollers 25, 25 ', and the lower roller 25' produces, in this position, the fourth side of a parallelepiped cage enclosing the cable 4.
  • the other three sides of the cage are, the lower roller 41 of the carriage and the side rollers 42, 42 'fixed to angles 56, 56'.
  • rollers 25, integral with the chains, are of course retracted and do not meet the cable guide bracket 60.
  • This chain comprises links 50 'guided between two upper angles 51' and between the lower angle 53 'and the guide rail 54'.
  • This chain comprises rollers 25, 25 ′ and in this position 25 ′ forms the fourth side of a parallelepipedal cage enclosing the cable.
  • the coiling operation is carried out as follows.
  • the cable leaving the chute 80 passes through the cable guide bracket 60, then through the carriage 30. It leaves the carriage via the distribution curve (31) giving it two different curvatures, one in the direction of the height and the other in a circumferential direction, then it falls into the tank where an operator manually forms the turns.
  • the carriage 30 is moved by a motorization and the operator has at hand a control box. For the unwinding operation. the cable does not pass either through the carriage or through the cable guide bracket which is then retracted.
