Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, specifically to a hanging device for the furnace door of a smelting furnace. Background Technology

[0002] In the aluminum alloy production and processing, the smelting furnace is an indispensable piece of equipment, and the normal opening and closing of the furnace door depends on its suspension equipment. Specifically, one end of the suspension component is detachably connected to the furnace door, and the other end is connected to a chain, which is then connected to lifting equipment such as a hydraulic cylinder.

[0003] Currently, most smelting furnace doors use screw-type hangers, which engage with the furnace door's slot via a square gasket at the bottom of the hanger and are then secured with bolts. However, this structure has significant drawbacks:

[0004] 1. When the hanging components are damaged, the disassembly and replacement operations are cumbersome, requiring a lot of time and manpower, which seriously affects production efficiency.

[0005] 2. The existing connection method between the hanging parts and the mounting base is relatively simple. During the frequent raising and lowering of the furnace door, loosening is likely to occur, resulting in insufficient connection stability. This may not only affect the normal operation of production, but also pose certain safety hazards.

[0006] 3. The hanging components are exposed to high-temperature baking environment for a long time, and the screw is prone to breakage, which may cause the furnace door to fall and thus affect production safety. Utility Model Content

[0007] The purpose of this utility model is to provide a hanging device for the furnace door of a smelting furnace, which solves the problems mentioned in the background art that the existing hanging parts are inconvenient and the connection is not stable enough.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a hanging device for a furnace door of a smelting furnace, comprising a mounting base disposed at the upper end of the furnace door and a hanging component disposed on the mounting base, wherein the mounting base is rectangular and has a T-shaped slot through one side; the hanging component consists of a connecting base and a T-shaped slot disposed at the bottom of the connecting base; the bottom of the slot is located in the slot and is adapted to the slot.

[0009] Furthermore, insertion holes are provided through the two side walls of the mounting base, and a groove is provided at the bottom of the slot.

[0010] Furthermore, a protrusion is vertically slidably connected to the lower part of the card holder, and sliding rods located inside the card holder are horizontally slidably connected to both sides of the bottom of the card holder. A push plate is vertically slidably connected to the upper part of the card holder. A first spring is connected between the protrusion and the lower part of the card holder. A second spring is sleeved on the sliding rod, and the two ends of the second spring are respectively connected to the sliding rod and the card holder. A third spring is sleeved on the upper part of the push plate, and the two ends of the third spring are respectively connected to the push plate and the upper part of the card holder.

[0011] Furthermore, a vertical groove is provided above the card holder, and a push rod that slides in cooperation with the groove is horizontally connected to the upper end of the push plate. A positioning block located outside the card holder is provided at the bottom of the push rod, and positioning holes are provided on both the positioning block and the outer wall of the card holder.

[0012] Furthermore, the connector has a connection hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Convenient and efficient disassembly and assembly: The hanging component adopts a structural design where the T-shaped bracket and the mounting base are matched with a T-shaped slot. Simultaneously, through the linkage mechanism of components such as push rods, push plates, slide rods, and protrusions, the hanging component and mounting base can be quickly installed and disassembled. When it is necessary to disassemble the hanging component, simply move the push rod upwards, causing the slide rod and protrusion to retract into the bracket, allowing the bracket to be easily removed from the slot. No complex tools are required, shortening disassembly and replacement time and improving production efficiency.

[0015] 2. Stable and Reliable Connection: During installation, after releasing the push rod, the second spring extends, causing the push plate to move downwards, allowing the protrusion to engage with the groove at the bottom of the slot. Simultaneously, the sliding rods engage with the insertion holes on both sides of the mounting base, forming a multi-directional limiting and fixing structure. This increases the contact area and friction between the hanging component and the mounting base, and also prevents the hanging component from loosening or falling off during furnace door raising and lowering through mechanical limiting, improving the stability and reliability of the connection and ensuring the safety and smooth operation of the production process.

[0016] 3. The hanging component of this utility model consists of a connecting seat and a clamp seat welded to it. By changing the screw structure of the traditional hanging component to a plate structure and increasing the cross-sectional area of ​​the clamp seat, the safe load-bearing capacity of the hanging component is improved, thereby further ensuring production safety.

[0025] Please see Figures 1 to 6 A hanging device for a smelting furnace door comprises mounting seats 2 symmetrically welded to both sides of the upper end of the furnace door 1 and hanging components 3 mounted on the mounting seats 2. The mounting seats 2 are rectangular with a T-shaped slot 4 extending through one side, and insertion holes 7 extending through both side walls of the mounting seats 2. A groove 8 is formed at the bottom of the slot 4. The hanging component 3 comprises a connecting seat 5 and a T-shaped bracket 6 located at the bottom of the connecting seat 5, with the bottom of the bracket 6 positioned within and fitted into the slot 4. A connecting hole 19 is formed on the connecting seat 5.

[0026] Specifically,

[0027] The card holder 6 has a first cavity and a second cavity sequentially formed from bottom to top inside, with the bottom of the first cavity located on the outer side of the bottom of the card holder 6; the cross-sections of both the first cavity and the second cavity are T-shaped. Positioning rods are welded to both sides of the bottom of the first cavity, and T-shaped protrusions 9 are slidably connected to the two positioning rods. A first spring 12 is fitted onto the positioning rod, with its two ends connected to the bottom of the first cavity and the upper part of the protrusion 9, respectively. Sliding holes are formed on both sides of the bottom of the card holder 6, and sliding rods 10 are horizontally slidably connected to both sliding holes. The sliding rods 10 are splined rods, and the sliding holes are adapted to them. The opposite ends of the two sliding rods 10 are wedge-shaped, and second springs 13 are fitted onto the two sliding rods 10, with their two ends connected to the upper part of the first cavity and one end of the sliding rod 10, respectively. A push plate 11 is vertically slidably connected to the second chamber. The bottom of the push plate 11 is also wedge-shaped. A third spring 14 is sleeved on the upper part of the push plate 11. The two ends of the third spring 14 are respectively connected to the upper part of the second chamber and the lower part of the push plate 11.

[0028] A vertical slide groove 15 communicating with the second chamber is provided above the card holder 6. A push rod 16 is horizontally connected to the upper end of the push plate 11. The push rod 16 slides with the slide groove 15 and one end of it extends to the outside of the card holder 6. A positioning block 17 located outside the card holder 6 is provided at the bottom of the push rod 16. Positioning holes 18 are provided on both the positioning block 17 and the outer wall of the card holder 6.

[0029] The hanging component 3 is composed of two vertically connectable parts joined together by bolts.

[0030] The working principle of this utility model is as follows: In the initial state, the first spring 12 and the second spring 13 are contracted, and the third spring 14 is in the extended state. At this time, the bottom of the push plate 11 is located in the first chamber, the two sliding rods 10 are pushed away by the push plate 11, move away from each other and extend out of the sliding hole, and the protrusion 9 moves down to the outside of the first chamber.

[0031] The hanging component 3 is installed in the mounting seat 2 on the furnace door 1 for connection with the hydraulic system to control the raising and lowering of the furnace door 1. First, the push rod 16 is moved upward, which in turn drives the push plate 11 to move upward. The third spring 14 retracts, at which point the protrusion 9 and the two sliding rods 10 are unrestrained. The first spring 12 and the second spring 13 extend, driving the protrusion 9 and the two sliding rods 10 back into the retaining seat 6. Then, the retaining seat 6 is placed in the retaining groove 4, so that the insertion hole 7 and the groove 8 on the retaining groove 4 are aligned with the sliding rods 10 and the protrusion 9. Then, the push rod 16 is released, the third spring 14 is unrestrained and extends, which in turn drives the push plate 11 to move downward. While pushing the protrusion 9 out into the groove 8, the two sliding rods 10 are pushed into the two insertion holes 7 respectively, and screws are screwed into the corresponding positioning holes 18 on the outer wall of the positioning block 17 and the retaining seat 6. Finally, a chain is connected to the connecting hole 19 on the connecting seat 5, and then the chain is connected to the hydraulic cylinder and other equipment to control the raising and lowering of the furnace door.
