Furnace body replacement auxiliary device

Abstract

This utility model discloses an auxiliary device for furnace body replacement, which includes two U-shaped steels installed on the right lifting end of a manual lifting trolley. Supporting rulers are welded to the bottom of the two U-shaped steels, and movable horizontal steel plates are provided at the top left end of the top of the two supporting rulers. Three bearing steel plates are welded to the top of the horizontal steel plates. This utility model allows the manual lifting trolley to raise the supporting rulers to a suitable height. Then, a drive assembly moves the horizontal steel plates, inserting the three bearing steel plates under the furnace body. The manual lifting trolley then operates, slightly lifting the furnace lining inside the furnace body with the three bearing steel plates. Finally, the drive assembly moves the three bearing steel plates out of the furnace body, thus removing the furnace lining. This achieves the purpose of using a telescopic structure in conjunction with the lifting trolley to form a bridge between the furnace body and the lifting trolley, enabling rapid movement to the lifting trolley for convenient replacement.

Description

Technical Field

[0001] This utility model belongs to the field of furnace body replacement technology, and in particular relates to an auxiliary device for furnace body replacement. Background Technology

[0002] Inside the electric furnace, the high temperature emitted by the electric arc melts the furnace charge and causes a reduction reaction to form an alloy. The furnace body is a cylindrical furnace chamber formed by the furnace lining. The three-phase electrodes are arranged vertically in an equilateral triangle in the upper part of the furnace chamber. The lower part of the electrodes is the main reaction zone. Electrical energy is converted into heat energy through the electric arc and resistance. The geometric dimensions such as the diameter and depth of the furnace chamber and the relative position of the electrodes and the furnace chamber have a great influence on the current distribution and temperature distribution inside the furnace. Since the reaction temperature is as high as 2000℃ or more, the volume of the furnace body is generally larger than the reaction space, so that a layer of furnace charge is left between the reaction zone and the furnace lining to protect the furnace lining.

[0003] The furnace body is in a high-temperature state for a long time during operation. The furnace lining material will crack and peel off due to repeated thermal expansion and contraction, resulting in thinning of the furnace wall. Therefore, it needs to be replaced regularly. Generally, the replacement is assisted by the machine door frame. In order to improve the convenience of furnace body replacement operation, we designed a furnace body replacement auxiliary device. It adopts a telescopic structure and works with a lifting cart to form a bridge between the furnace body and the lifting cart, so that it can be quickly moved to the lifting cart for easy replacement.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A furnace body replacement auxiliary device includes two U-shaped steels installed on the right lifting end of a manual lifting vehicle. Support rulers are welded to the bottom of the two U-shaped steels. A movable horizontal steel plate is provided at the left end of the top of the two support rulers. Three bearing steel plates are welded to the top of the horizontal steel plate. A moving drive assembly is provided between the horizontal steel plate and the two support rulers. The moving drive assembly includes two symmetrical L-shaped steels welded between the two support rulers. A threaded rod is rotatably connected between the two L-shaped steels. A threaded sleeve is threadedly connected to the surface of the threaded rod. The top of the threaded sleeve is fixedly connected to the horizontal steel plate.

[0006] Preferably, a motor is fixedly installed on the left side of the L-shaped steel on the left side, and the output shaft of the motor is fixedly installed with the threaded rod.

[0007] Preferably, two symmetrical support rails are fixedly connected between the two L-shaped steels, and the surfaces of the support rails are slidably connected with sliding sleeves, the tops of which are fixedly connected to the horizontal steel plate.

[0008] Preferably, two symmetrical omnidirectional pulleys are installed on both sides of the bottom of the manual lifting vehicle, and two symmetrical directional pulleys are installed on the right side of the bottom of the manual lifting vehicle.

[0021] Working principle: When using this utility model, the user controls the height of the U-shaped steel 2 and the support ruler 3 by operating the foot pedal on the manual lifting cart 1, so that the supporting steel plate 5 above the support ruler 3 is raised to a suitable height. Then, the motor 63 drives the threaded rod 62 to rotate, and the threaded rod 62 drives the threaded sleeve 64 to move. The threaded sleeve 64 drives the horizontal steel plate 4 and the supporting steel plate 5 to move, so that the three supporting steel plates 5 are moved to the bottom of the furnace lining inside the furnace body. Then, the manual lifting cart 1 operates the support ruler 3 to raise, so that the supporting steel plates 5 slightly lift the furnace lining. Then, the motor 63 reverses, so that the threaded sleeve 64 drives the horizontal steel plate 4 and the supporting steel plate 5 to move, moving the furnace lining out of the furnace body, which is convenient for replacing the furnace lining inside the furnace body.

[0022] In summary: This furnace body replacement auxiliary device, by operating the manual lifting trolley 1 to raise the support ruler 3 to a suitable height, then the moving drive assembly 6 drives the horizontal steel plate 4 to move, so that the three supporting steel plates 5 are inserted under the furnace body. Then, the manual lifting trolley 1 works, driving the three supporting steel plates 5 to slightly lift the furnace lining inside the furnace body. Then, the moving drive assembly 6 drives the three supporting steel plates 5 to move out of the furnace body, thus removing the furnace lining from the furnace body. This achieves the purpose of using a telescopic structure in conjunction with the lifting trolley to form a bridge between the furnace body and the lifting trolley, allowing for quick movement to the lifting trolley for convenient replacement.
