Detailed ways

An embodiment of the cable pay-off device of the present invention is shown in Figures 1 to 7, which is a cable pay-off device for secondary wiring of a switch cabinet, including a cable base 10 for supporting a cable reel, a set The bracket on the cable base 10 and the cable reversing mechanism arranged on the bracket are used to change the final drawing direction of the cable 70 .

The top surface of the cable base 10 is a plane extending in the horizontal direction, and the bracket is arranged in the middle of the left and right directions of the cable base 10, adopts a frame structure and the vertical part is a plane structure, and isolates the cable base 10 into left and right sides. part, forming the isolation bracket 20. The position on the left side of the isolation bracket 20 on the cable base 10 forms two I-shaped wheel support structures arranged in front and back, and two I-shaped wheels 50 can be placed at the same time. The position on the right side of the isolation bracket 20 on the cable base 10 forms two disc-shaped cable support structures arranged one after the other, which can place two disc-shaped cables at the same time.

The top of the spacer frame 20 is provided with a circular frame 21 extending left and right, the left and right sides of the circular frame 21 are all overhanging on the spacer frame 20, and the part on the right side of the circular frame 21 is provided with a portal frame 22 with an opening facing downwards. The front and the rear of the gantry 22 are respectively fixed with vertical rings whose axes extend along the horizontal direction to form a cable reversing mechanism. The vertical rings at the front and the rear all include two annular bodies juxtaposed up and down, forming respectively the vertical ring 41 of the I-shaped wheel passing through the cable 70 that is located on the I-shaped wheel 50 and the vertical ring 41 for itself to be formed. The vertical coil 31 through which the cable 70 of the coil passes is used to change the final leading-out direction of the corresponding cable 70 . In order to ensure the structural strength, a diagonal brace 23 is provided between the portal frame 22 and the top of the spacer bracket 20 . The part on the left side of the ring frame 21 is fixed with two horizontal rings whose axes extend in the vertical direction, forming the horizontal ring 40 of the I-shaped wheel for the cables 70 wound on the I-shaped wheel 50 to pass through. Two horizontal rings whose axes extend in the vertical direction are also fixed on the middle crossbeam in the height direction of the spacer bracket 20 , forming a horizontal ring 30 for coiled cables to pass through. The horizontal circular ring 40 of the I-shaped wheel and the horizontal circular ring 30 of the cable form a cable straightening ring, and each cable straightening ring is used to compress the corresponding cable 70 and slide with the cable 70 when the cable 70 is in use. A bend occurs between the cable base 10 and the cable reversing mechanism, forming a friction correction part. Through the cable correction ring, the cable 70 can rely on the friction of the friction correction part to correct the torsional force and control the sliding speed, effectively preventing the cable from being knotted during the cable pay-off process. The isolation bracket 20 adopts a frame structure, which is simple in structure, light in weight, flexible in movement, takes up less space, and is easy to use. In order to avoid interference between the two cable reels, the heights of the vertical ring 31 of the wire coil and the vertical ring 41 of the I-shaped wheel are both higher than the horizontal ring 40 of the I-shaped wheel.

The cable pay-off device also includes an auxiliary pay-off device 80 for the I-shaped wheel. Rotate the rotating rod 83 that is arranged on the top of the spool 50 . The central position of the pressure plate 81 is provided with a step through hole, and a positioning sleeve 82 for inserting into the perforation of the I-shaped wheel 50 and positioned radially along the I-shaped wheel 50 is fixed in the step through hole. A counterweight 84 is fixed to the end passing through the center of the positioning sleeve 82 and protruding out. The counterweight 84 is used to axially limit the rotating rod 83 and enable the pressure plate to be stably supported on the end surface of the I-shaped wheel 50 To prevent the cable 70 from slipping off from the I-shaped wheel 50 when pulling the cable 70.

The ring 88 is used for the cable 70 passing through the cable guide ring 86 to pass through, so that the cable 70 can move upwards smoothly and ensure that the cable 70 on the I-shaped wheel 50 can be uncoiled smoothly.

When in use, place the cable 70 wound with the I-shaped wheel 50 on the I-shaped wheel support structure on the left side of the cable base 10 and adjust the position so that the friction correction part on the I-shaped wheel transverse ring 40 is in the I-shaped wheel. The wheel support structure is on the axis coaxial with the I-shaped wheel 50, and then the end of the cable on the I-shaped wheel 50 passes through the cable guide ring 86, the direction changing ring 88, the I-shaped wheel transverse ring 40 and the I-shaped wheel. The vertical ring 41 of the wheel is finally connected to the off-line machine; meanwhile, the end of the disc-shaped cable is passed through the horizontal ring 30 and the vertical ring of the coil on the right side of the isolation bracket 20 successively. 31. Finally connect to the off-line machine. During the wiring process, the unwinding machine pulls the corresponding cable 70 to move to realize the uncoiling of the two cable reels. When each cable 70 passes through the corresponding horizontal ring 30 of the coil or the horizontal ring 40 of the I-shaped wheel, it can be connected with the corresponding horizontal ring 40. The friction correction part of the ring generates friction, thereby correcting the torsion of the cable 70 and controlling the sliding speed of the cable 70, preventing knotting of the cable during unwinding. The structure is simple and easy to use.

In the above-mentioned embodiment, the support is an isolation support 20, and two cable trays can be arranged on both sides of the isolation support 20, so that four cables 70 can be offline simultaneously, meeting the requirements of most offline machines. In addition, the cable reversing mechanism and the cable correction ring are both composed of a complete circular ring body. In other embodiments of the present utility model, the bracket can also be arranged on one side of the cable base 10, and the cable tray support structure is arranged on the other side of the cable base 10, while the number of cable trays on the isolation bracket 20 It can also be increased or decreased as needed. In addition, the cable reversing mechanism and the cable correction ring can also be replaced with other forms, such as a half ring, an oval ring, and the like.
