[0002] In power construction, cables have many uses, mainly for control installation, equipment connection and power transmission. With the popularization and improvement of various power facilities, in order to strengthen and expand the coverage of power facilities, it is necessary to lay cables over a large area. Among them, cable pulling devices are one of the common winding and unwinding devices.

[0003] Existing traction devices use take-up rollers to wind up and unwind cables. The end of the take-up roller is equipped with a drive component to rotate it and achieve automatic winding. This has the advantage of simple operation. However, most of the current take-up rollers are fixedly installed on the traction frame and cannot be replaced, which makes it difficult to meet the usage requirements. Utility Model Content

A cross plate is connected to the top of the drive block after passing through the through slot, and a guide cylinder is connected to the top of the cross plate via a support rod.

[0010] Furthermore, the base plate has two sliding grooves below the movable plate, and two sliders that are slidably connected to the sliding grooves are fixed to the bottom of the movable plate.

[0011] Furthermore, the movable plate is fixed to the base plate by bolts.

[0012] Furthermore, a limiting strip is fixed to the side of the positioning cylinder, and a limiting groove adapted to the limiting strip is opened on the inner side of the wire storage roller.

A traction mechanism for pulling cables is installed on the top of the base plate 1 on one side of the clamping mechanism.

[0022] The clamping mechanism includes a fixed plate 4 and a movable plate 5. A central shaft 6 is rotatably mounted through both the fixed plate 4 and the movable plate 5. A limit plate 7 is fixedly connected to one end of each of the two central shafts 6 that is close to each other. A positioning cylinder 8 is fixedly connected to the side of the limit plate 7. The fixed plate 4 is fixedly connected to the base plate 1, and a motor 9 is mounted on its side via a support plate. The output shaft of the motor 9 is connected to the central shaft 6 via a coupling. Two sliding grooves are opened below the movable plate 5 on the base plate 1. Two sliders 20 that are slidably connected to the sliding grooves are fixedly connected to the bottom of the movable plate 5. The movable plate 5 is fixed to the base plate 1 by bolts. A limit strip is fixedly connected to the side of the positioning cylinder 8. A limit groove that matches the limit strip is opened on the inner side of the wire storage roller 2.

[0023] A PLC controller is installed on the side of the fixed plate 4. The fixed plate 4 and the movable plate 5 are clamped and fixed to the wire storage roller 2 by two positioning cylinders 8. The motor 9 drives the central shaft 6 to rotate, which can drive the wire storage roller 2 to rotate. By controlling the forward and reverse rotation of the motor 9, the winding or unwinding of the wire storage roller 2 can be realized.

[0024] The traction mechanism includes a fixed column 13, which is hollow inside and has a through groove at its top. A drive block 14 is slidably connected inside the fixed column 13, and a lead screw 15 is rotatably installed inside the fixed column 13. The lead screw 15 passes through and is threadedly connected to the drive block 14, and one end of the lead screw 15 passes through the side of the fixed column 13 and is connected to the output shaft of the second motor 16 via a coupling. A horizontal plate 17 is connected to the top of the drive block 14 after passing through the through groove. A guide cylinder 19 is connected to the top of the horizontal plate 17 via a support rod 18.

[0025] Motor 2 16 drives lead screw 15 to rotate, causing drive block 14 to move guide cylinder 19, which can realize the adjustment of the position of guide cylinder 19. By controlling the forward and reverse rotation of motor 2 16, guide cylinder 19 can move back and forth along through groove.

[0026] A support base 10 is movably installed on the top of the base plate 1 between the fixed plate 4 and the movable plate 5. The top surface of the support base 10 is an arc-shaped surface adapted to the wire storage roller 2, and an installation groove is opened on its top surface.

A connecting rod 22 connected to the fixed plate 4 / movable plate 5 is fixedly connected to the side of the circular plate 21.

[0027] The support base 10, together with the support roller 11, can support the wire storage roller 2. When the wire storage roller 2 needs to be replaced, remove the bolts on the movable plate 5 and pull it outward so that the two circular plates 21 move to the end face close to the support base 10. At this time, the wire storage roller 2 is located on the support base 10 and separated from the two positioning cylinders 8. Adjust the position of the inclined pad 12 and push the wire storage roller 2 to remove and replace it.

[0028] In practical use, the fixed plate 4 and the movable plate 5 clamp and fix the wire storage roller 2 through two positioning cylinders 8. The motor 1 9 drives the central shaft 6 to rotate, which can drive the wire storage roller 2 to rotate. The motor 2 16 drives the lead screw 15 to rotate, causing the guide cylinder 19 to move back and forth along the through groove, which can realize the winding or unwinding of the wire storage roller 2.

[0029] Remove the bolts on the movable plate 5 and pull it outward so that the wire storage roller 2 is located on the support base 10 and separated from the two positioning cylinders 8. Adjust the position of the inclined pad 12, and push the wire storage roller 2 to remove and replace it. This can be operated by a single person, which is convenient and quick.
