Motor-driven tipping device of slag pot car and working procedure thereof

Abstract

The invention discloses a motor-driven tipping device of a slag pot car and a working procedure thereof. The motor-driven tipping device comprises a worm reduction gear, a moment idler wheel, a guiding rail, a planet cycloid pinwheel reduction gear and a chain and sprocket device, wherein the worm reduction gear is connected with a trunnion of a slag pot supported frame by a retaining plate and suspended on the trunnion; the planet cycloid pinwheel reduction gear is arranged at the upper part of the worm reduction gear and is connected with the worm of the worm reduction gear by the chain and sprocket device; and the moment idler wheel is fixed at the lower part of the worm reduction gear and is arranged in a guide rail. The method comprises two steps of deslagging and returning. Since the invention adopts the worm reduction gear and the moment idler wheel for replacing two parallel screws and nut skid frame driving devices, transmission mechanisms are simplified and the transmission efficiency is increased. The electromotor of the 24m<3> motor-driven tip-over slag pot car only needs 11kw power; compared with the power of the original motor-driven tip-over slag pot car, the power is reduced by 19kw, thus greatly reducing the energy consumption.

Description

technical field [0001] The invention relates to a slag tank transport vehicle in the field of iron and steel metallurgy, in particular to an electric tilting device and a working method of the slag tank transport vehicle. Background technique [0002] For many years, steel mills have used electric tipping devices for slag tankers driven by two parallel lead screws and nut carriages. Such as Figure 3-4 As shown, the electric tipping device of the existing slag tank car includes a motor 8, a reducer 9, a pinion 10, a lower large gear 11, an upper large gear 12, a lower screw 13, an upper screw 14, a carriage 15, and a support 16 , the torque of the motor 8 of the electric tilting device of the slag tanker is transmitted to the lower large gear 11 through the reducer 9 and the pinion 10, and the lower large gear 11 is transmitted to the upper large gear 12, and the lower large gear 11 drives the lower lead screw 13 rotates, the upper large gear 12 drives the upper lead screw ...

AI Technical Summary

Problems solved by technology

Due to the low efficiency of the device and the large axial force of the screw, a 16m 3 The electric dumping slag tank truck requires a motor power of 16kW, and a 24m 3 The electric dumping slag tanker requires a motor power of 30kW; due to its complex structure, the device requires a large amount of maintenance work, and the production cost and maintenance cost are relatively high
