AI Technical Summary
The traditional chain transmission hot-sending roller has the effect of equipment failure chain, the motor reducer is easily affected by high temperature, and the roller body is easily stuck in the casting blank, affecting the push of the casting blank.
Using parallel-moving force transmission, each hot-sending roller is driven by an independent motor and reducer, which avoids the chain effect of equipment failure and designs the motor reducer to the opposite side of the casting blank, reducing the impact of high temperature. At the same time, the roller end chamfer and guide roller edge are designed at the end of the roller body to facilitate the push and transport of the casting blank.
Each roller is able to run independently, and even if several rollers fail, it will not affect the overall hot transfer, reducing the fault of the motor reducer, and the casting billet is pushed smoothly.

Abstract
Description
Technical Field
[0001] The utility model relates to a hot charging roller table for continuous casting billets with horizontal power transmission, belonging to the technical field of continuous casting and rolling mill equipment in the metallurgical industry. Background Art
[0002] The hot charging roller table of the billet continuous caster is a casting billet transportation channel connecting the billet continuous casting production line and the rolling line. The continuous casting billets produced by the continuous caster are pushed from the billet unloading area of the continuous caster to the hot charging roller table by a transverse steel shifting car, and then transported to the rolling line by the hot charging roller table for rolling. The traditional hot charging roller table is driven by a motor and a reduction gearbox, and all the rollers are driven centrally through a chain transmission device. The characteristics of this transmission mode are:
[0003] (1) The space required for equipment installation is not too large, and the consumed spare parts are not many;
[0004] (2) This transmission mode has a simple structure and is convenient for installation.
[0005] However, this transmission mode with many advantages has the following defects:
[0006] (1) This chain transmission adopts a typical series drive. As long as one device in the series breaks down, the subsequent devices will be paralyzed, which will affect the hot charging of continuous casting billets;
[0007] (2) The motor reducer is installed on the side where the transverse steel shifting car pushes the casting billets. The motor reducer is baked by the high-temperature casting billets and is prone to failure;
[0008] (3) When the continuous casting billets are pushed from the billet unloading area of the continuous caster to the hot charging roller table by the transverse steel shifting car, the roller body of the hot charging roller table is prone to jamming the casting billets, which is not conducive to the pushing of the casting billets. Content of the Utility Model
[0009] The purpose of the utility model is to provide a hot charging roller table for continuous casting billets with horizontal power transmission. Each hot charging roller has an independent power source. Even if several rollers fail, it will not affect the overall hot charging of the hot charging roller table, and it also avoids the baking of the motor reducer by the high-temperature casting billets, facilitates the transportation of the casting billets, and solves the problems existing in the background art.
[0010] The technical solution of the utility model is:
[0011] A hot charging roller table for continuous casting billets with horizontal power transmission includes several rollers arranged in parallel. Each roller is driven by a motor and a reducer. One end of the roller body of each roller is provided with a roller end chamfer, and the other end is provided with a guide roller edge. The motor and the reducer are drivingly connected to the end of the roller body with the guide roller edge.
[0012] One end of the roller body with a roller end chamfer is fixed with a right end cover, and a right shaft is fixed on the right end cover. The right shaft is rotatably connected to the right bearing seat; one end of the roller body with a guiding roller edge is fixed with a left end cover, and a left shaft is fixed on the left end cover. The left shaft is rotatably connected to the left bearing seat, and the motor and the speed reducer are drivingly connected to the left shaft.
[0013] The left bearing seat is fixed on the left roller path support, and the right bearing seat is fixed on the right roller path support.
[0014] The roller body is of a hollow structure.
[0015] The guiding roller edge is fixedly connected to the end of the roller body to form an integral structure, and its height is matched with the outer dimension of the continuous casting billet.
[0016] The beneficial effects of the present utility model are as follows:
[0017] (1) For the hot charging roller path of continuous casting billets with flat power transmission, each hot charging roller has an independent power source and is driven in parallel. Even if several rollers fail, it will not affect the hot charging of the overall hot charging roller path, and the faulty hot charging rollers can be repaired during scheduled maintenance.
[0018] (2) For the hot charging roller path of continuous casting billets with flat power transmission, the motor and the speed reducer are designed on the opposite side of the transverse steel transfer car pushing the continuous casting billet, avoiding the baking of the high-temperature continuous casting billet and reducing the failures of the motor and the speed reducer.
[0019] (3) When the continuous casting billet is pushed from the billet unloading area of the continuous casting machine to the hot charging roller path by the transverse steel transfer car, the roller end chamfer is conducive to the transverse steel transfer car pushing the continuous casting billet onto the hot charging roller path, and the guiding roller edge facilitates the guiding function of the hot charging roller path during the transportation of the continuous casting billet.
