Description

Technical Field

[0001] The present invention relates to the technical field of AOD furnace displacement, and more particularly to an AOD wheel retainer device. Background Art

[0002] There are two modes for AOD stainless steel smelting, one is a fixed AOD furnace, similar to a converter, and the other is a mobile vehicle-mounted AOD furnace, which has the advantage of convenient and quick maintenance such as replacing the furnace shell. The mobile vehicle-mounted AOD is to install the entire AOD furnace equipment on a mobile frame. The wheel system of the frame adopts a 4X4 structure layout to move on double tracks from the maintenance position to the smelting position. Due to the large impact load and vibration during the smelting process, the wheel system will be damaged. Therefore, after the frame moves to the smelting position, the wheel system is lifted up by the hydraulic lifting device to leave the track, and the entire frame will fall on a separate load-bearing support. The entire wheel system is in a protected state without any load at this time. However, the wheel system is fixed to the telescopic rod of the hydraulic cylinder. During the lifting and lowering process of the wheel system and the vibration during the AOD smelting process, the wheel system will deflect. Because the hydraulic lifting cylinder itself does not have an anti-deflection function, the wheel system may not be able to accurately fall on the track when it falls off the track. The purpose of this equipment is to prevent the wheel system from deflecting and causing the wheel to fall off the track, causing the frame to fail to work properly. During the entire process of lifting and lowering the wheel system, the position of the wheel is kept from deflecting. Summary of the invention

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1

[0030] from Figure 1-2 It can be seen that an AOD wheel cage device of this embodiment includes an AOD frame 1, a wheel assembly 3 and a hydraulic lifting cylinder 4. The hydraulic lifting cylinder 4 is fixed to the inner side of the AOD frame 1, and the output end of the hydraulic lifting cylinder 4 is fixedly connected to the wheel assembly 3. The wheel cage 2 is arranged on the upper part of the axle of the wheel assembly 3. Figure 3 It can be seen that the wheel assembly 3 is lifted and lowered vertically under the action of the wheel holder 2 .

[0031] The outer cylinder sleeve of the hydraulic lifting cylinder 4 is fixed to the AOD frame 1 through a flange, and the end of the inner telescopic rod at the output end of the hydraulic lifting cylinder 4 is fixedly connected to the wheel assembly 3. A single wheel assembly 3 adopts a 2X2 layout of 4 wheels and runs on double tracks.

[0032] from Figure 4-5 It can be seen that the wheel holder 2 is composed of a guide seat 21 , an extension plate 22 , a reinforcing rib 23 , a horizontal limit baffle 24 , and a vertical limit baffle 25 , and the wheel holder 2 is fixedly mounted on the AOD frame 1 .

[0033] The guide seat 21 is detachably assembled with the AOD frame 1 by means of fixing bolts. The extension plate 22 is fixedly connected to the bottom of the guide seat 21 , and a reinforcing rib 23 is welded between the extension plate 22 and the guide seat 21 .

[0034] An L-shaped opening 221 is disposed at the bottom of the extension plate 22 . A horizontal limit baffle 24 and a vertical limit baffle 25 are disposed inside the L-shaped opening 221 . The horizontal limit baffle 24 and the vertical limit baffle 25 are fixed to each other.

[0035] The horizontal limit baffle 24 and the vertical limit baffle 25 are perpendicular to each other, and grease is applied on the plate surfaces of the horizontal limit baffle 24 and the vertical limit baffle 25. A limit abutment column 26 is arranged at the connection between the horizontal limit baffle 24 and the vertical limit baffle 25, and the limit abutment column 26 produces a limiting effect.

[0036] The vertical limit baffle 25 is parallel to the vertical center line of the wheel axle of the wheel assembly 3, and there is a gap of 0.5 mm between the vertical limit baffle 25 and the wheel axle.

[0037] like Figure 1 As shown in the initial installation position, the horizontal limit baffle 24 and the vertical limit baffle 25 at the end of the wheel holder 2 are just flush with the center line of the wheel axle of the wheel assembly 3, and a gap of 0.5mm is retained to prevent rigid contact. Grease is applied to the two limit baffles at the end of the wheel holder 2. When the telescopic rod of the hydraulic lifting cylinder 4 is lifted, the entire wheel assembly 3 is driven to rise. The wheel axle of the wheel assembly 3 will maintain vertical lifting under the action of the horizontal limit baffle 24 and the vertical limit baffle 25 of the wheel holder 2, and will not deflect or shake. When lifted to the specified position, it will remain in a fixed state.

[0038] During the smelting process of AOD, although the frame vibrates severely, the center of the wheel assembly 3 is always consistent with the center line of the track under the limiting effect of the wheel holder 2, and vice versa, during the descent of the wheel assembly 3, the wheel axle is limited by the wheel holder 2, and the wheel of the wheel assembly 3 will fall steadily on the track without deflection, ensuring the normal movement of the wheel on the track. At the same time, when the wheel assembly 3 moves on the track, it can also prevent the wheel from deflecting and derailing.

[0039] from Figure 6-7 It can be seen that a plate surface protrusion 251 is provided on the plate surface of the vertical limit baffle 25, and correspondingly, an axle body positioning groove 31 is provided on the axle body of the wheel axle. The axle body positioning groove 31 and the plate surface protrusion 251 are complementary in shape and have no contact.

[0040] The gap between the axle body positioning groove 31 and the plate surface protrusion 251 can avoid the rigid contact between the vertical limit baffle 25 and the wheel axle. At the same time, the plate surface protrusion 251 can produce a rapid positioning and axial constraint effect on the wheel axle. The relative position of the axle body positioning groove 31 and the plate surface protrusion 251 can be observed to achieve the purpose of daily rapid maintenance, avoid the initial position of the vertical limit baffle 25 from being offset, and ensure its stability and accuracy during operation.

[0041] The plate surface protrusion 251 can also be replaced by a rolling body, and the two sides of the rolling body are in rolling contact with the vertical limit baffle 25 and the wheel axle respectively, so as to achieve the effect of auxiliary lifting.

[0042] It effectively prevents the wheel system from deflecting and causing the wheel to fall off the track, which causes the frame to fail to work properly. During the entire process of raising and lowering the wheel system, the wheel position is kept from deflecting.

[0043] The present invention has the advantages of simple structure, strong rigidity, convenient installation, maintenance-free and strong pertinence, and can effectively target the wheel assembly system of the mobile vehicle-mounted AOD furnace, prevent the wheel assembly 3 from deflecting during the lifting process, prevent the wheel from deflecting when falling off the track, and also prevent the wheel assembly 3 from deflecting during walking or when the track moves, thereby improving the safety of the system, maintaining the long-term reliable operation of the wheel system and avoiding damage to the wheel system.

[0044] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
