Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of vacuum furnace technology, specifically to a protective structure for a high-temperature vacuum furnace. Background Technology
[0002] When heat treating workpieces in a high-temperature vacuum furnace, it is generally advisable to use multi-layer pallets to stack the workpieces inside the furnace. When taking the workpieces out, a forklift can be used to remove the stacked pallets from the furnace. During this process, it is necessary to avoid the forklift forks damaging the inner wall of the furnace.
[0003] The inventors proposed a protective structure for a high-temperature vacuum furnace. A cantilever crane is added to the outside of the high-temperature vacuum furnace to provide suspension support and protection for the pallets pulled out from inside the furnace. This moves the forklift's material handling area from inside the furnace to the outside, avoiding potential interference between the forklift and the furnace due to limited space, and improving the safety of material handling operations in the high-temperature vacuum furnace.

[0040] The support column 4 has a support 41 welded to its top. The top of the support 41 is movably connected to a rotating frame 5. A suspension 6 is fixed to the outside of the rotating frame 5.
[0041] In this embodiment, limiting holes 21 are fixed on the top and bottom left and right sides of the bracket 2. The two limiting holes 21 located on the top and bottom of one side of the bracket 2 are detachably snapped into the top and bottom of the limiting rod 22. Multiple slide rails 23 are fixed in pairs on the left and right sides of the inner wall of the bracket 2.
[0042] The limiting rod 22 is assembled on the left and right sides of the bracket 2 through the limiting hole 21 to maintain the distance between the left and right sides of the bracket 2 and the inner wall of the high temperature furnace 1.
[0043] In this embodiment, a slide 31 is fixedly provided on both the left and right sides of the bottom of the tray 3. The bottom of the slide 31 is slidably connected to the top of the slide rail 23. A weight reduction hole is fixedly provided in the middle of the tray 3.
[0044] The slide rail 31 at the bottom of the pallet 3 can slide above the slide rail 23, allowing the pallet 3 to slide in and out of the high-temperature furnace 1. This makes it convenient for users to place loose parts directly on the pallet 3 or use a forklift to place framed workpieces on the pallet 3.
[0045] In this embodiment, a drive motor 42 is fixedly mounted on the rear side of the support 41, a first spur gear 43 is fixedly mounted on the top output end of the drive motor 42, a second spur gear 51 is fixedly mounted on the bottom of the rotating frame 5, and the rear side of the second spur gear 51 meshes with the front side of the first spur gear 43.
[0046] The drive motor 42 drives the first spur gear 43 to rotate.
