In the prior art, the transport chain and rollers transport wires during movement, which may result in thinner wires being unable to be transported, while thicker wires may come into contact and cause wear. The distance between each receiving seat is a fixed value, and a "one-to-one" mode is usually adopted, that is, one wire diameter corresponds to one model of step transport structure, which is difficult to apply in production processes where the wire diameter varies.

[0003] Therefore, a wire stepping transport chain structure is needed to improve upon the above-mentioned shortcomings. Utility Model Content

[0011] Preferably, the gear transmission assembly comprises a main gear connected to the transmission shaft by a key, a driven gear coaxial with the driving sprocket and connected by a key, and a chain connecting the two gears;

[0012] The torque output by the power motor is delivered to the drive sprocket via a transmission shaft connected by a rigid coupling and then transmitted through the chain of the gear transmission assembly.

[0013] The chain tension in the gear transmission assembly is adjusted by a tensioning wheel, which is installed perpendicular to the chain and has a slot in the installation direction. It can move in the direction perpendicular to the chain to tighten or loosen the chain.

A power motor is installed on one side of the bottom of the chain bed body, and a transmission shaft is installed at the output end of the power motor.

[0017] Preferably, rollers are installed inside the outer and inner links, and a copper sleeve is installed in the middle of the rollers.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This utility model provides a wire stepping transport chain structure.

[0020] 1) Place the wire on the V-groove transport chain, start the power motor to drive the main gear to rotate, the rotation of the main gear drives the driven gear to rotate, the rotation of the chain drives the driven gear to rotate, the rotation of the driven gear drives the drive sprocket to rotate, the rotation of the drive sprocket drives the outer chain link, inner chain link and drive sprocket to rotate, during the rotation process, the wire is transported through the outer chain link and inner chain link, the V-groove transport chain installed on the inner chain link and drive sprocket has a V-shaped structure;

[0021] For the three types of wire diameters (50-100mm, 100-180mm, and 180-400mm) placed on the V-groove transport chain, one diameter is selected respectively. Among them, the transport mode of the small diameter wire (50-100mm) corresponding to the 80mm wire can transport one wire in each V-groove unit of the V-groove transport chain.

[0022] For 168mm wire, the transportation mode for medium-diameter wires of 100-180mm is to transport two wires using three V-groove units;

[0023] For 230mm wire, the transportation mode for large diameter wires of 180-400mm involves multiple V-groove units between two wires. This structure can accommodate wires of various thicknesses and lengths, increasing the range of applications while allowing for cyclical transportation and effectively preventing slippage during transport.

[0024] 2) By starting the power motor, the main gear is driven to rotate, which in turn drives the driven gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the drive sprocket to rotate. At least one set of drive shafts and rigid couplings connected to the shaft of the drive sprocket and gear transmission assembly can synchronously link multiple chain bed bodies to achieve the function of multi-group linkage to reduce energy consumption, and can also be adapted to wires of more lengths.

[0025] 3) Rollers support and roll inside the outer and inner links; the rollers are connected to their mounting pins by copper sleeves; spacers are added between the rollers and the inner walls of the outer and inner links to prevent mechanical wear caused by direct contact; the mounting pins pass through both sides of the outer and inner links and are limited by cotter pins.

[0026] 4) The chain tension adjusting screw can adjust the tension of the V-groove transport chain. A nut corresponding to the chain tension adjusting screw is rigidly connected to the axle of the driven sprocket. When the chain tension adjusting screw is rotated, the nut drives the driven sprocket to move along the axial direction of the chain tension adjusting screw. By changing the distance between the driven sprocket and the driving sprocket, the V-groove transport chain composed of outer and inner chain links sleeved on the driven sprocket and the driving sprocket is tensioned and loosened, so as to realize the function of easy tensioning.

The V-groove transport chain 2 installed on the inner link 203 and drive sprocket 204 has a V-shaped structure.

[0043] For the three wire diameters (50-100mm, 100-180mm, and 180-400mm) placed on the V-groove conveyor chain 2, one diameter is selected respectively. Figure 3 As illustrated in the diagram, the transportation mode for small-diameter wires (50-100mm) corresponding to 80mm wires is such that each V-groove unit of the V-groove transportation chain 2 can transport one wire.

[0044] For 168mm wire, the transportation mode for medium-diameter wires of 100-180mm is to transport two wires using three V-groove units;
