Abstract

The invention discloses a lifting assembly and a smelting furnace with the same. The lifting assembly includes a frame, a lift and a lifting beam. The elevator is arranged on the frame, and the elevator includes a power device and a screw rod. The power device is connected with the screw rod to drive the screw rod to rotate. The lifting beam is movably arranged on the frame, and the lifting beam is rotatable relative to the screw rod. According to the lifting assembly of the present invention, by setting the connection relationship between the elevator and the lifting beam, the rotary motion of the screw rod on the elevator can be converted into the linear motion of the lifting beam, so that the lifting beam can move along the axial direction of the screw rod. Low precision, high motion precision and a large speed reduction ratio, can quickly realize the operation. And the spiral movement is a structure capable of completing the self-locking function, and the thread on the screw rod can engage with the thread on the lifting beam, so that the lifting beam can be parked on the screw rod.

Description

technical field [0001] The invention relates to the field of industrial technology, in particular to a lifting component and a smelting furnace with the same. Background technique [0002] In industrial fields such as smelting, non-ferrous metals and foundry equipment manufacturing, it is necessary to spray oxygen into the smelting furnace for heating to accelerate combustion. In the related art, the oxygen lance can inject oxygen at a fixed point, and can have a lifting action, but the oxygen lance cannot move laterally. And the electric motor is hoisted with a steel wire rope, and the steel wire rope itself is a kind of elastic material, the control precision is not high, and the frequency conversion speed regulation range of the motor is narrow. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a lifting assembly, which has the advanta...
