DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 1 and Figure 3As shown, in this embodiment, a cable production unwinder includes a base plate 1, a mounting groove 3 is opened on the top outer wall of the base plate 1, a support assembly 4 is installed inside the mounting groove 3, the support assembly 4 includes two movable rods 401 placed inside the mounting groove 3, the tops of the two movable rods 401 are rotatably connected to two support rods 402, one end of the top of the four support rods 402 is rotatably connected to the same receiving plate 403, a hydraulic cylinder 404 is fixedly installed on the outer walls at both ends of the base plate 1, and the output ends of the two hydraulic cylinders 404 are fixedly connected to the two movable rods 401 respectively.

[0025] The top outer wall of the receiving plate 403 is provided with a plurality of placement grooves 406 distributed at equal distances, and the plurality of placement grooves 406 are all arranged in an inverted triangle shape.

[0026] The body of the wire reel is placed in the two placement grooves 406. Since the placement grooves 406 are in the shape of an inverted triangle, it can be ensured that the position of the wire reel will not change arbitrarily when it is in the placement grooves, and it is located in the middle of the receiving plate 403. Then the two hydraulic cylinders 404 are started. The hydraulic cylinders 404 respectively drive the two moving rods 401 away from each other, and the bottom end of the support rod 402 connected to them will also be driven to move synchronously. Since the top position is fixed, the support rod 402 will gradually turn in the vertical direction, and the receiving plate 403 and the wire reel position thereon will also be gradually lifted up until they reach a height suitable for installation. The adjustment process is convenient and stable enough.

[0027] like Figure 2 and Figure 4 As shown, a positioning plate 2 is fixedly connected to both sides of the top outer wall of the base plate 1, and a same rotating component 5 is installed between the two positioning plates 2.

[0028] The rotating assembly 5 includes the same rotating shaft body 501 that is slidably inserted between the two positioning plates 2. A limiting groove 502 is opened in the middle of the rotating shaft body 501. Two moving blocks 503 are slidingly connected inside the limiting groove 502. A plurality of connecting rods 504 are rotatably connected inside the two moving blocks 503. The same moving plate 505 is rotatably connected relative to the two connecting rods 504.

[0029] A bidirectional screw rod 506 is rotatably connected inside the rotating shaft body 501 , and the two moving blocks 503 are respectively threadedly sleeved on the threads at both ends of the bidirectional screw rod 506 , and one end of the bidirectional screw rod 506 is fixedly connected to a handle.

[0030] Pass the rotating shaft body 501 through the two positioning plates 2 and the hole of the wire drum, then connect one end of the rotating shaft body 501 to the external transmission device, and then use the handle to drive the bidirectional screw rod 506 to rotate in the limit groove 502. The two moving blocks 503 restricted by the limit groove 502 will be driven closer to each other, and the moving block 503 can drive the moving plate 505 to move out of the limit groove 502 through the connecting rod 504 until the moving plate 505 is tightly attached to the inner ring of the wire drum, and the fixation is completed.

[0031] like Figure 1 As shown, two limit rods 405 are fixedly connected to the inner walls at both ends of the installation groove 3, and the two moving rods 401 are slidably sleeved outside the two limit rods 405, which can increase the stability of the overall state of the moving rod 401 and prevent its position from changing arbitrarily.

[0032] like Figure 2 As shown, the lead angles of the threads at both ends of the bidirectional screw 506 are smaller than the equivalent friction angle, making it self-locking, thereby ensuring that the position of the moving block 503 will not change arbitrarily.

[0033] The utility model provides a cable production pay-off device, the specific working principle of which is as follows:

[0034] When the device is working, first use the lifting equipment to place the wire drum on the top of the receiving plate 403, and make the wire drum body be in the two placement grooves 406. Since the placement grooves 406 are in the shape of an inverted triangle, it can ensure that the position of the wire drum will not change arbitrarily when it is in the grooves, and it is in the middle of the receiving plate 403. Then start the two hydraulic cylinders 404, which respectively drive the two moving rods 401 away from each other, and the bottom end of the support rod 402 connected to it will also be driven to move synchronously. Because the top position is fixed, the support rod 402 will gradually turn towards the vertical direction, and the receiving plate 403 and the upper part thereof will be moved vertically. The position of the wire drum will also be gradually lifted up until it reaches a height suitable for installation. The adjustment process is convenient and stable enough. Then, the shaft body 501 is passed through the two positioning plates 2 and the wire drum hole, and then one end of the shaft body 501 is connected to the external transmission device. The bidirectional screw rod 506 is driven to rotate in the limit groove 502 by the handle, and the two moving blocks 503 restricted by the limit groove 502 will be driven closer to each other. The moving block 503 can drive the moving plate 505 to move out of the limit groove 502 through the connecting rod 504 until the moving plate 505 is tightly attached to the inner ring of the wire drum, and the fixation is completed.
