Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment technology, specifically relating to an auxiliary device for loading and unloading materials in a vacuum furnace. Background Technology

[0002] Vacuum furnaces are widely used in metal heat treatment, ceramic sintering, semiconductor processing, and other fields. Their working environment typically requires high cleanliness, no oxidation, and low pollution. During the loading and unloading process of a vacuum furnace, auxiliary equipment is usually needed to smoothly and efficiently feed or remove materials (such as trays, workpieces, etc.) into or out of the furnace chamber.

[0003] Currently, common auxiliary equipment for loading and unloading materials in vacuum furnaces mainly uses forklifts or similar handling devices. Traditional forklift equipment is typically equipped with a fixed pallet or fork structure for carrying and transporting materials. However, existing technology has the following drawbacks:

[0004] Large space occupation: The pallet or fork of traditional forklifts is usually fixed and cannot be folded when not in use, resulting in a large space occupation when storing the equipment, which is not conducive to the optimization of workshop layout.

[0005] To address the aforementioned issues, there is an urgent need for a vacuum furnace loading and unloading auxiliary device that is simple in structure, foldable, and occupies little space.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary device for loading and unloading materials in a vacuum furnace, so as to solve the problems of the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An auxiliary device for loading and unloading materials in a vacuum furnace includes a front lifting plate fixed to the front of a forklift via a lifting drive device. Two symmetrically arranged vertical plates are fixed to the front side wall of the front lifting plate. Each vertical plate has a support plate with an L-shaped vertical cross-section rotatably connected to its outer side near its bottom end via two rotating shafts. Each support plate has an opening near the rotating shaft. A dual-purpose fixing component is installed on the front side wall of each vertical plate. The dual-purpose fixing component is used to fix the unfolded support plate and the folded support plate.

[0010] Preferably, the dual-purpose fixing assembly includes a sliding groove opened on the front side wall of the vertical plate, a sliding seat with a convex cross-section slidably connected in the sliding groove, and an insertion part with an isosceles trapezoidal cross-section integrally formed at the front end of the sliding seat.

[0011] Preferably, the tray has a first insertion groove at one end near the rotating shaft that mates with the bottom end of the insertion part, and a second insertion groove at the front end of the tray that mates with the bottom end of the insertion part. The depth of the second insertion groove is the same as the depth of the first insertion groove.

[0012] Preferably, a positioning post is movably inserted through the sliding seat, and the front end of the positioning post extends movably into a groove opened in the front side wall of the insertion part, and is fixedly connected with a pull ring.

[0013] Preferably, the rear end of the positioning post extends movably to the back of the sliding seat and is movably inserted into the first positioning hole opened in the inner wall of the sliding groove. Above the first positioning hole, a second positioning hole is also provided in the inner wall of the sliding groove, and the second positioning hole is close to the top of the vertical plate.

[0014] Preferably, the top of the positioning post is fixedly connected to a slider with an inverted convex structure in the vertical section. The slider is slidably connected to a groove opened at the top of the sliding seat, and the front end of the slider is also fixed to the inner wall of the groove by a spring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The auxiliary equipment for loading and unloading materials in a vacuum furnace of this utility model can be folded by first manually pulling the pull ring and pushing the sliding seat up to a position close to the top wall of the sliding groove. Then, the pallet is flipped and folded parallel to the vertical plate through two rotating shafts. After that, the sliding seat is manually pushed down so that the insertion part at the front end of the sliding seat can be inserted and fixed in the second insertion groove opened at the front end of the pallet, thereby fixing the pallet after folding. Then, the positioning pin is inserted into the second positioning hole under the reverse action of the spring to fix it. When unfolding, the pallet is flipped to a 90-degree angle with the vertical plate and the sliding seat is manually pushed down so that the insertion part at the front end of the sliding seat is inserted into the first insertion groove. At this time, the positioning pin is manually inserted into the first positioning hole, thereby fixing the pallet after unfolding. This allows the pallet to be folded when not in use, avoiding the problem of occupying a large space when storing the equipment, which is not conducive to the optimization of the workshop layout. At the same time, it can also further fix the unfolded pallet to prevent the material from moving up and down during loading and unloading, thus avoiding safety hazards. Attached Figure Description

[0028] See attached document Figure 1-5 An auxiliary device for loading and unloading materials in a vacuum furnace includes a front lifting plate 11 fixed to the front side of a forklift device 1 via a lifting drive device 111. Two symmetrically arranged vertical plates 12 are fixed to the front side wall of the front lifting plate 11. Each vertical plate 12 has a support plate 14 with an L-shaped vertical cross section rotatably connected to its outer side near its bottom end via two rotating shafts 13. Each support plate 14 has an opening 141 near the rotating shaft 13. A dual-purpose fixing component 2 is installed on the front side wall of each vertical plate 12. The dual-purpose fixing component 2 is used to fix the unfolded support plate 14 on one hand and to fix the folded support plate 14 on the other hand.

[0029] Furthermore, such as Figure 1-5 As shown, in order to fix the folded or unfolded tray 14, a dual-purpose fixing component 2 is provided, including a sliding groove 211 opened on the front side wall of the vertical plate 12. A sliding seat 21 with a convex cross-section is slidably connected in the sliding groove 211. The front end of the sliding seat 21 is integrally formed with an insertion part 22 with an isosceles trapezoidal cross-section. A first insertion groove 23 is opened on the tray 14 near the pivot 13, which mates with the bottom end of the insertion part 22. A second insertion groove is opened on the front end of the tray 14, which mates with the bottom end of the insertion part 22. The depth of the second insertion groove is the same as the depth of the first insertion groove 23. A positioning device is movably inserted through the sliding seat 21. The front end of the positioning post 24 extends movably into the groove 28 opened on the front side wall of the insertion part 22 and is fixedly connected to the pull ring 27. The rear end of the positioning post 24 extends movably to the back of the sliding seat 21 and is movably inserted into the first positioning hole 29 opened in the inner wall of the sliding groove 211. Above the first positioning hole 29, there is also a second positioning hole 210 opened in the inner wall of the sliding groove 211. The second positioning hole 210 is close to the top of the vertical plate 12. The top of the positioning post 24 is fixedly connected to the slider 25 with an inverted convex structure in the vertical section. The slider 25 is slidably connected to the sliding groove opened at the top of the sliding seat 21. The front end of the slider 25 is also fixed to the inner wall of the sliding groove by a spring 26.

[0030] Appendix Figure 4 The inner wall of the movable opening 141 shown in the diagram facing the front side wall of the vertical plate 12 is movably attached to the front side wall of the vertical plate 12, thus ensuring that the support plate 14 and the vertical plate 12 are in a 90-degree perpendicular state.

[0032] In actual use, when folding the tray 14, first, manually pull the pull ring 27 and push the sliding seat 21 upward to a position close to the inner top wall of the sliding groove 211. Then, flip and fold the tray 14 parallel to the vertical plate 12 using the two pivots 13. After that, manually push the sliding seat 21 downward so that the insertion part 22 at the front end of the sliding seat 21 can be inserted and fixed in the second insertion groove opened at the front end of the tray 14, thereby fixing the tray 14 after folding. Then, the positioning post 24 is inserted into the second positioning hole 210 under the reverse action of the spring 26 to achieve fixation. When unfolded, Flip the pallet 14 to a 90-degree angle with the vertical plate 12, and manually push down the sliding seat 21 so that the insertion part 22 at the front end of the sliding seat 21 is inserted into the first insertion slot 23. At this time, the positioning post 24 is manually inserted into the first positioning hole 29, thereby fixing the pallet 14 after it is unfolded. This allows the pallet 14 to be folded when not in use, avoiding the problem of occupying a large space when storing equipment, which is not conducive to optimizing the workshop layout. At the same time, it can also further fix the unfolded pallet 14 to prevent the material from moving up and down during loading and unloading, which could cause safety hazards.
