Description

Technical Field

[0001] The utility model relates to the field of cable stranding, and specifically relates to a cable clamping device in the production of high-voltage cables. Background Art

[0002] A cable stranding machine, also known as a stranding machine or a winding machine, is a mechanical device that can be widely used in the stranding of various soft / hard conductor wires (such as copper wires, enameled wires, tinned wires, copper-clad steel, copper-clad aluminum, etc.). It twists multiple single-conductor wires into one strand to meet the process requirements of the wire. It has a wide range of applications in the wire and cable industry and is one of the important devices for producing high-quality wire and cable products.

[0003] During the cable stranding and forming process, the wire reel is placed on the basket rack and fixed by a clamping mechanism to prevent the wire reel from shaking or displacing during the stranding process, thereby affecting the stranding quality and the uniformity of the cable. Currently, the main method is still manual clamping. However, in the case of a large and heavier wire reel, manual clamping can no longer meet the usability and safety of the product, which will affect the stability of the cable stranding. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cable clamping device in the production of high-voltage cables, which effectively solves the problem that manual clamping of the wire reel can no longer meet the requirements and causes unstable clamping when the cross-section of the cable is large and heavy during the cable forming process.

[0005] The technical solution of the utility model is as follows:

[0006] A cable clamping device in the production of high-voltage cables includes a large winch and a small winch arranged front and back. A basket rack is provided between the large winch and the small winch. There are connecting components between the basket rack and the large winch and the small winch. Symmetrically arranged on the basket rack are large basket rack clamping sprockets for clamping the wire reel. On one side of the basket rack close to the small winch, symmetrically arranged are basket rack cross-bridge sprocket shafts. Respectively symmetrically arranged on the basket rack cross-bridge sprocket shafts are a first basket rack cross-bridge small sprocket and a second basket rack cross-bridge small sprocket. The first basket rack cross-bridge small sprocket and the large basket rack clamping sprocket are cooperated with each other through a chain. On the inner frame of the basket rack and on the side of the basket rack cross-bridge sprocket shaft far from the large basket rack clamping sprocket, there is a basket rack clamping motor output shaft. A third basket rack cross-bridge small sprocket is provided on the basket rack clamping motor output shaft. The third basket rack cross-bridge small sprocket and the second basket rack cross-bridge small sprocket are also cooperated with each other through a chain. An externally powered basket rack clamping motor is provided on the basket rack clamping motor output shaft. Power rotation components are provided at the front and rear ends of the basket rack.

[0007] Further, the small chain wheel I of the basketball stand cross bridge is arranged at a position near the outer end of the basketball stand cross bridge sprocket shaft, and symmetrically arranged on the basketball stand cross bridge sprocket shaft are basketball stand cross bridge shaft fixing sleeves that fit on the basketball stand.

[0008] Further, the connecting component includes a basketball stand shaft, a winch bearing, and a winch bearing seat. The basketball stand shaft is connected to the front and rear ends of the basketball stand, and the winch bearings are symmetrically installed on the basketball stand shaft.

[0009] Further, an aviation industry plug is provided at the end of the basketball stand shaft connected to the large winch. The aviation industry plug is electrically connected to the basketball stand clamping motor, and a storage battery is provided on the wall of the large winch. The storage battery is electrically connected to the aviation industry plug.

[0010] Further, a connecting winch coupling shaft is provided between the large winch and the small winch. A main gearbox shaft is connected to the winch coupling shaft, and a main gearbox is connected to the main gearbox shaft.

[0011] Further, a main gearbox end cover helical gear is provided on the main gearbox shaft. The main gearbox end cover helical gear is located between the main gearbox and the large winch, and is provided on the main gearbox end cover helical gear.

[0012] Further, a torsion relief helical gear is provided on one side of the basketball stand shaft located at the large winch. A cross bridge helical gear shaft parallel to the winch coupling shaft is provided on the large winch. A cross bridge helical gear is provided on the cross bridge helical gear shaft. The cross bridge helical gear cooperates with the torsion relief helical gear, and the cross bridge helical gear cooperates with the main gearbox end cover helical gear.

[0013] A stranding tube is installed on one side of the small winch away from the winch coupling. A wire dividing board is connected to the head of the stranding tube, and the wire passes through a 12° wire division and enters the die device for overall stranding.

[0014] The advantages of the present utility model are:

[0015] 1. By arranging the output shaft of the basketball stand clamping motor on the basketball stand in the present utility model, driving its rotation causes the small chain wheel III of the basketball stand cross bridge to rotate. With the cooperation of the small chain wheel II and the small chain wheel I of the basketball stand cross bridge, the large chain wheel for clamping the basketball stand rotates, thereby enabling the locking and fixing of the wiring disk on the basketball stand. When manufacturing heavy cables, the electric clamping method is safer than manual clamping, can effectively prevent the situation of wire core shaking, and improves the stability of the stranding process.

[0016] 2. By providing an aviation industry plug on the basket frame shaft and installing a storage battery on the large winch, power can be supplied to the aviation industry plug to provide electricity for the basket frame clamping motor. By using a storage battery, the standby time is long and the maintenance cost is low.

[0017] 3. The utility model meshes the untwisting helical gear and the intermediate helical gear and finally combines with the helical gear on the end cover of the main gearbox. By adopting an internal planetary gear structure, the transmission ratio is guaranteed to be 1:1, which can ensure that the basket frame always runs horizontally with the winch body, improving the stability during the cable stranding process.
