Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, specifically a furnace bottom roller replacement device for a heat treatment furnace. Background Technology

[0002] A heat treatment furnace refers to an electric or fuel-fired furnace used for heating furnace charge for heat treatment. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces, and salt bath furnaces. Continuous furnaces are typically used, with workpieces continuously loaded through the charging door, passing through the furnace chamber, and continuously discharged through the discharging door. The furnace bottom rollers are key components in continuous annealing production lines, primarily used to support and convey steel coils, ensuring uniform heating and cooling of the steel under high-temperature conditions.

[0003] During use, furnace bottom rollers often bulge or break. Replacing furnace bottom rollers is a frequent maintenance item for heat treatment furnaces. Currently, when replacing furnace bottom rollers, they are usually disassembled and installed manually, and they also need to be transported. Generally, there are many furnace bottom rollers in heat treatment furnaces, which is very physically demanding for workers. In addition, during installation, the sides of the furnace bottom rollers may be damaged, which may affect subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a furnace bottom roller replacement device for a heat treatment furnace to solve the problems mentioned in the background art.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0022] Please refer to Figure 1-4 This utility model discloses a furnace bottom roller replacement device for a heat treatment furnace, comprising a mounting base 1 and a furnace bottom roller body 11. The furnace bottom roller body 11 is the furnace bottom roller of the heat treatment furnace, and the device is used to replace the furnace bottom roller body 11. The mounting base 1 is the main mounting structure of the device, used to install other structures and replace the furnace bottom roller body 11. The mounting base 1 is provided with a placement groove 12, and the furnace bottom roller body 11 is placed on the placement groove 12 on both sides, thereby being supported by the mounting base 1. A limiting plate 13 is provided on the rear side of the placement groove 12, which is used to limit the two sides of the furnace bottom roller body 11. A mounting plate 14 is provided above the mounting base 1. The mounting plate 14 is a mounting structure. Limiting rods 22 are provided on both sides of the placement groove 12, and the top of the limiting rods 22 are connected to the mounting plate 14, that is, the mounting plate 14 is supported by the limiting rods 22.

[0023] The mounting plate 14 has a fixing mechanism at its bottom for fixing both sides of the furnace bottom roller. The fixing mechanism includes a fixing plate 2, with an arc-shaped groove 21 on the bottom inner side of the fixing plate 2. Limiting ports 24 are provided on both sides of the fixing plate 2, and the limiting ports 24 are slidably connected to the limiting rods 22. A threaded opening 32 is provided on the inner side of the mounting plate 14, and a threaded rod 3 is provided inside the threaded opening 32. The threaded rod 3 is threadedly connected to the threaded opening 32. A first movable block 31 is provided at the bottom of the threaded rod 3. A first movable groove 23 is provided on the top inner side of the fixing plate 2. 1 is movably connected to the first movable groove 23, that is, the first movable block 31 is locked in the first movable groove 23 and rotates, that is, the threaded rod 3 rotates in the threaded opening 32, thereby causing the threaded rod 3 to rise and fall in the threaded opening 32, and the first movable block 31 moves in the first movable groove 23, thereby driving the fixed plate 2 to rise and fall, and the limiting rod 22 limits the limiting opening 24, thereby keeping the fixed plate 2 stable when rising and falling, so that the arc groove 21 is above the furnace bottom roller, that is, by tightening the threaded rod 3, the furnace bottom roller is fixed.

[0024] A base plate 4 is provided below the mounting base 1, and wheels 44 are provided at the bottom of the base plate 4. The base plate 4 serves as the bottom structure of the device, supporting the overall structure and moving the device via the wheels 44, thus facilitating the disassembly and replacement of the furnace bottom roller. An electric push rod 41 is provided on the upper inner side of the base plate 4, and a second movable bolt 42 is provided at the top of the electric push rod 41. A second movable groove 43 is provided at the bottom of the mounting base 1, and the second movable bolt 42 is movably connected to the second movable groove 43. That is, the second movable bolt 42 connects to the second movable groove 43, thereby connecting the base plate 4 to the mounting base 1. The base plate 4 supports the mounting base 1, and the second movable bolt 42 moves in the second movable groove 43, allowing the top of the mounting base 1 to rotate, thus facilitating the placement of the groove 12 to align with the side of the furnace bottom roller. The electric push rod 41 drives the mounting base 1 to rise and fall, thus facilitating the disassembly and installation of the furnace bottom roller.

[0025] The working principle of this utility model is as follows: The device is moved by the wheel 44, which facilitates the disassembly and replacement of the furnace bottom roller. When disassembling the furnace bottom roller, the second movable bolt 42 moves in the second movable groove 43, thereby rotating the top of the mounting base 1. This facilitates the placement groove 12 to align with the side of the furnace bottom roller. The mounting base 1 is raised and lowered by the electric push rod 41, so that the two sides of the furnace bottom roller are placed on the two side placement grooves 12 respectively. The two sides of the furnace bottom roller are limited by the limiting plate 13. The threaded rod 3 rotates in the threaded opening 32, thereby raising and lowering the threaded rod 3 in the threaded opening 32. The first movable block 31 moves in the first movable groove 23, thereby raising and lowering the fixing plate 2. The limiting opening 24 is limited by the limiting rod 22, so that the fixing plate 2 remains stable when it is raised and lowered, so that the arc groove 21 is above the furnace bottom roller. The furnace bottom roller is fixed by tightening the threaded rod 3. After the furnace bottom roller is fixed, it is supported by the electric push rod 41 for replacement. The reverse is to install it.

[0026] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
