Description

Technical Field

[0001] This utility model relates to the field of roasting furnace climbing technology, specifically a roasting furnace unloading ladder suspension mechanism. Background Technology

[0002] Prebaked anodes are the most important and advanced anode type in the current aluminum electrolysis industry. They are carbon blocks that have undergone high-temperature roasting in a specialized roasting furnace to achieve the desired physicochemical properties. They are typically rectangular in shape with a groove at the top for connecting a guide rod. During the electrolysis of alumina to produce primary aluminum, current flows through the anode into the electrolytic cell and participates in the electrochemical reaction (carbon combines with oxygen to produce carbon dioxide). Therefore, the anode is continuously consumed and needs to be replaced periodically.

[0003] The roasting process in prebaked anodes is a crucial step in production. Its purpose is to heat-treat the formed "green anodes" (made from a mixture of petroleum coke, pitch, etc.) at high temperatures. The green anode blocks enter the roasting workshop for pre-furnace preparation. The loading of the carbon blocks is done manually, using steel wire ropes to tie them together. After roasting, the filling material in the furnace chamber is placed into the material pool via a multi-functional suction trolley. Then, workers climb ladders into the furnace chamber and tie the materials together with steel wire ropes. The trolley then lifts the materials out of the furnace chamber and places them into the next automatic carbon block cleaning process for cleaning, ultimately yielding the final product.

[0004] To facilitate inspection, maintenance, and material loading / unloading operations, fixed ladders are typically installed on the outer wall of the furnace. However, because the furnace temperature is very high during production, the fixed ladders directly connected to the furnace absorb a large amount of heat, causing the ladder body temperature to become excessively high, posing a risk of burns to personnel. Furthermore, prolonged exposure to heat may also affect the ladder's structural strength.

[0005] To address the aforementioned issues, existing technologies often employ detachable suspended ladders, which suspend the ladder above the furnace opening using a horizontal bar. However, the lack of securing the horizontal bar to the furnace wall makes it easy for workers to slide left or right or even fall during the climb, posing a safety hazard. Utility Model Content

[0006] This utility model addresses the aforementioned shortcomings of existing technologies by providing a suspension mechanism for a roasting furnace unloading ladder. A detachable anti-slip mechanism is fitted onto the crossbeam, which effectively prevents axial sliding of the crossbeam. This fundamentally solves the problem of ladder slippage during use, greatly improving safety and making the machine safer and more reliable to use. To achieve the above objectives, this utility model provides the following technical solution: A suspension mechanism for a roasting furnace exit ladder includes a crossbeam for suspending the ladder. Both ends of the crossbeam are fitted with detachable anti-slip mechanisms. The suspension mechanism includes a sleeve that cooperates with the crossbeam. The sleeve is provided with a locking plate to prevent the sleeve from sliding on the crossbeam. A spring clip for fixing the locking plate is provided below the sleeve.

[0007] Preferably, a positioning rod is vertically connected to one end of the crossbeam. Preferably, the upper and lower ends of the sleeve are provided with clearance holes that cooperate with the locking plate. The lower end of the locking plate extends out from the clearance hole below, and the elastic clamp rests on the locking plate. The upper end of the locking plate is provided with a locking hole that cooperates with the crossbeam. The side wall of the locking plate is provided with an ear plate, which is connected to the sleeve through a first rotating shaft.

[0008] Preferably, the upper end of the crossbeam is uniformly provided with locking grooves that mate with the upper end of the lock hole. Preferably, the lower end of the sleeve is connected to a positioning ring, and the elastic clamp includes a first grip and a second grip connected by a second rotating shaft. The first grip is fixed to the inner wall of the positioning ring, and the side wall of the second grip abuts against the lower end of the locking plate. A torsion spring connecting the first grip and the second grip is provided on the second rotating shaft.

[0009] Preferably, the side wall of the first grip is provided with a locking bolt for fixing the second grip.

[0010] Preferably, the end of the positioning ring closest to the furnace wall is flush with the sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a detachable anti-slip mechanism fitted on the crossbeam. With the obstruction of the anti-slip mechanism, the crossbeam can be effectively prevented from sliding axially, which fundamentally solves the problem of slippage during the use of the ladder, greatly improves safety, and makes it safer and more reliable to use.

[0012] 2. This utility model utilizes a spring clip to push the lock plate, achieving automatic reset and locking of the lock plate. During disassembly, simply press the second handle to overcome the spring force and disengage the lock plate from the lock groove, thus easily removing the sleeve from the crossbeam. The entire operation can be completed with one hand, requiring no tools, saving time and effort, and greatly improving work efficiency.

[0013] 3. The locking bolt provided on the first grip of this utility model can be tightened after the lock plate is in place to fix the second grip, preventing it from being accidentally pressed and causing the lock plate to unlock accidentally, thus playing a double insurance role.

[0014] 4. Multiple locking grooves evenly arranged on the crossbeam allow the suspension mechanism to be fixed at multiple positions on the crossbeam, adapting to different working requirements.

[0015] 5. The design of the positioning ring not only provides an installation base for the elastic clamp, but its structure, with one end close to the furnace wall flush with the sleeve, also makes the entire mechanism more stable when installed close to the furnace wall and less prone to shaking.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, a roasting furnace outlet ladder suspension mechanism includes a crossbeam 1 for suspending the ladder 6. Both ends of the crossbeam 1 are fitted with detachable anti-slip mechanisms. The suspension mechanism includes a sleeve 2 that cooperates with the crossbeam 1. The sleeve 2 is provided with a locking plate 3 to prevent the sleeve 2 from sliding on the crossbeam 1. A spring clip 5 for fixing the locking plate 3 is provided below the sleeve 2.

[0019] A positioning rod 101 is vertically connected to one end of the crossbeam 1. After the crossbeam 1 is placed, the positioning rod 101 can prevent the crossbeam 1 from rotating.

[0020] like Figure 2 As shown, both the upper and lower ends of the sleeve 2 are provided with clearance holes 201 that mate with the locking plate 3. The lower end of the locking plate 3 extends out from the lower clearance hole 201, and the spring clip 5 rests against the locking plate 3. Figure 3As shown, the upper end of the locking plate 3 is provided with a locking hole 301 that cooperates with the crossbeam 1, and the side wall of the locking plate 3 is provided with an ear plate 302. The ear plate 302 is connected to the sleeve 2 through the first rotating shaft 303.

[0021] The upper end of the crossbeam 1 is evenly provided with locking grooves 102 that mate with the upper end of the locking holes 301, preventing the anti-slip mechanism from sliding and improving the reliability of use. The multiple locking grooves 102 evenly provided on the crossbeam 1 allow the suspension mechanism to be fixed at multiple positions on the crossbeam 1, adapting to different working requirements. like Figure 4 As shown, the lower end of the sleeve 2 is connected to a positioning ring 4. The elastic clip 5 includes a first handle 504 and a second handle 505 connected by a second rotating shaft 502. The first handle 504 is fixed to the inner wall of the positioning ring 4 by bolts. The side wall of the second handle 505 presses against the lower end of the lock plate 3. A torsion spring 503 is provided on the second rotating shaft 502 to connect the first handle 504 and the second handle 505. The torsion spring 503 pushes the second handle 505 open, so that the second handle 505 presses against the lock plate 3. When the second handle 505 is gripped, it moves closer to the first handle 504. The lock plate 3 will rotate under the action of gravity and remain vertical. The upper end of the lock plate 3 will disengage from the lock groove 102 to unlock. After releasing, under the action of the torsion spring 503, the second handle 505 will push the lock plate 3 to rotate, so that the upper end of the lock plate 3 will cooperate with the lock groove 102 to lock and fix it.

[0022] The side wall of the first grip 504 is provided with a locking bolt 501 for fixing the second grip 505. When the second grip 505 is opened, that is, after the lock plate 3 is engaged with the lock groove 102, rotating the locking bolt 501 can fix the second grip 505. A positioning hole is provided on the second grip 505 to mate with the locking bolt 501, ensuring the reliability of locking. The locking bolt 501 provided on the first grip 504 can be tightened after the lock plate 3 is in place to fix the second grip 505, preventing it from being accidentally pressed and causing the lock plate 3 to be accidentally unlocked, thus providing a double safety function.

[0023] The end of the positioning ring 4 closest to the furnace wall is flush with the sleeve 2, which allows the positioning ring 4 to be placed closer to the furnace wall, making the entire mechanism more stable and less prone to shaking when installed close to the furnace wall.

[0024] like Figure 5As shown, in use, the anti-slip mechanism and the ladder 6 (with a sleeve at the upper end that mates with the crossbeam 1) are fitted onto the crossbeam 1. The distance between the two anti-slip mechanisms is adjusted according to the size of the furnace opening so that the positioning ring 4 is just against the inner wall of the furnace, and the locking groove 102 faces upward when the crossbeam 1 is placed. The spring clip 5 is used to push the locking plate 3, realizing the automatic reset and locking of the locking plate 3. During disassembly, simply press the second handle 505 to overcome the spring force and disengage the locking plate 3 from the locking groove 102, thereby easily removing the sleeve 2 from the crossbeam 1. The entire operation can be completed with one hand, without any tools, saving time and effort and greatly improving work efficiency.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
