Description

Technical Field

[0001] This utility model relates to the field of oxygen-free copper casting technology, and in particular to a lifting device for an upward continuous casting furnace used in oxygen-free copper production. Background Technology

[0002] The upward continuous casting technology is the core process for oxygen-free copper production. It uses a traction mechanism to vertically draw the solidified billet upwards from the crystallizer, forming high-purity, low-oxygen copper. In this process, the stability and continuity of the lifting device directly determine the billet quality and production efficiency. However, existing technologies mostly use a single motor to drive the lifting of a single continuous casting rod, which is not only inefficient but also requires the entire production line to be shut down for repairs should the drive motor fail.

[0003] To address this, we designed an upward lifting device for oxygen-free copper production continuous casting furnaces that has redundant driving capability and can simultaneously drive two continuous casting rods. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses an upward continuous casting furnace lifting device for oxygen-free copper production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hoisting device for an upward continuous casting furnace used in oxygen-free copper production includes:

[0007] Continuous casting rods, consisting of two spaced-apart rods;

[0008] A drive chain is located between two continuous casting rods; the drive chain has a vertical section on the side near the continuous casting rod, and the upper end of the continuous casting rod is connected to the vertical section at a nearby position.

[0009] A drive sprocket engages with the drive chain;

[0010] The drive motor has two motors, and the output ends of both drive motors are driven and connected to the drive sprocket shaft.

[0011] When one drive motor fails, the other drive motor takes over the operation.

[0012] Furthermore, it also includes a drive frame, wherein the top and bottom of the end of the drive frame near the continuous casting rod are provided with transmission sprockets, and the drive chain is wound around the two transmission sprockets to form the vertical state section.

[0013] Furthermore, the top of the drive frame is provided with a vertical slide groove, and a tension sprocket that can slide up and down is installed in the vertical slide groove to press against the drive chain and keep it in a tensioned state.

[0014] Furthermore, the continuous casting rod and the drive chain are fixedly connected by fasteners to ensure that the continuous casting rod moves up and down synchronously with the vertical movement of the chain.

[0015] Furthermore, the bottom of the drive frame is provided with a support base for fixing the frame to the upper continuous casting furnace.

[0016] Furthermore, the vertical slide groove is equipped with a spring or hydraulic damper for dynamically adjusting the downward pressure of the tension sprocket.

[0017] Furthermore, the drive motor is a three-in-one motor that integrates a brake and a reducer.

[0018] Furthermore, the two drive motors are symmetrically arranged on both sides of the drive frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The system adopts a symmetrical layout of two drive motors. When one drive motor fails, the other drive motor can take over the operation, solving the problem of production stoppage caused by single point failure and ensuring the continuous operation of the oxygen-free copper continuous casting production line.

[0021] 2. The arrangement of the drive chain and transmission sprocket enables the simultaneous lifting and lowering of two continuous casting rods (one rising and the other falling) via the drive chain, thus improving continuous casting efficiency;

[0022] 3. The drive chain forms a vertical section through the transmission sprocket. The tension of the drive chain is dynamically adjusted in conjunction with the tension sprocket to eliminate transmission gaps, ensure the verticality of the continuous casting rod's lifting trajectory, and avoid traction deviation.
