Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber component products, and in particular to a steel ladle cover plate for a nano-level high-temperature heat-insulating ceramic fiber component product. Background Technology

[0002] Nanoscale high-temperature insulating ceramic fiber components are a high-performance material designed specifically for insulation and protection needs in extreme high-temperature environments. Combining the advantages of nanotechnology and ceramic materials, they possess excellent high-temperature resistance, insulation, and mechanical properties, and are widely used in aerospace, industry, energy, and other fields.

[0003] The ladle cover is an important piece of equipment used to cover the top of the molten steel ladle during the steel smelting process. It is mainly used for heat preservation, reducing heat loss, preventing oxidation and splashing of molten steel, and improving production efficiency and steel quality.

[0004] Currently, cover plates are commonly used to insulate molten steel ladles. However, existing molten steel ladle cover plates are usually fixed to the molten steel ladle with bolts and nuts, and there is no way to quickly remove the cover plates. Therefore, opening and closing the cover plates requires manual removal of bolts and nuts, which consumes a lot of time and reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a steel ladle cover plate for a molten steel tank made of nano-level high-temperature heat-insulating ceramic fiber components. This solves the problem that the existing technology does not have a convenient way to quickly remove the cover plate, so the bolts and nuts need to be removed manually when opening and closing the cover plate, which consumes a lot of time.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixing mechanism is installed on the body of the molten steel tank. The fixing mechanism includes a fixing plate. The cover plate body is installed on the fixing plate. Several fixing clips are provided on the outside of the molten steel tank body. The fixing clips are matched with the molten steel tank body. Several sliding strips are slidably installed inside the fixing plate. The fixing clips are connected to the sliding strips. A first gear is provided on the fixing plate.

[0008] The installation of the fixing plate facilitates the fastening with the molten steel ladle body, ensuring a secure fixation. The installation of the fixing clip facilitates the closing action with the molten steel ladle body, ensuring that the cover plate covers the molten steel ladle body for heat preservation while also ensuring a tight connection. The installation of the sliding strip facilitates the control of the movement of the fixing clip, enabling it to clamp the molten steel ladle body. The installation of the first gear facilitates rotational movement, allowing the limiting rod to slide when in motion.

[0009] As an improvement, a limiting rod is fixedly installed on the sliding bar, the limiting rod passes through the first gear, and the first gear has a limiting groove that matches the limiting rod.

[0010] The installation of the limit rod facilitates the sliding action according to the rotation of the first gear, thereby making it easier to control the sliding action of the sliding bar.

[0011] As an improvement, a support rod is installed on the fixed plate, the first gear is rotatably mounted on the support rod, and a second gear is provided on the fixed plate.

[0012] The support rod provides support, thus facilitating the installation of the first gear and enabling it to rotate. The second gear, on the other hand, drives the first gear to rotate during rotation.

[0013] As an improvement, the second gear meshes with the first gear, and a bracket is fixedly mounted on the fixed plate.

[0014] The bracket provides support, protects the mechanism on the fixed plate, and facilitates the installation of the motor.

[0015] As an improvement, an electric motor is mounted on the bracket, and the electric motor passes through the bracket and is connected to the second gear.

[0016] The installation of the electric motor facilitates the conversion of electrical energy into mechanical energy, thereby facilitating the rotation of the second gear.

[0017] As an improvement, the auxiliary mechanism is mounted on the fixed mechanism. The auxiliary mechanism includes a first protective pad, which is mounted on a fixed clamp. A first slot matching the first protective pad is cut into the body of the molten steel ladle.

[0018] The installation of the first protective pad facilitates the buffering of the contact force on the molten steel ladle body when the fixing clamp comes into contact with it, making the clamping clamp and the molten steel ladle body more securely engaged.

[0019] As an improvement, a pair of shock absorbers are fixedly installed on the fixing clamp, and a second protective pad is installed on the shock absorber. A second groove matching the second protective pad is cut into the body of the molten steel tank, and a spring is provided on the outer sleeve of the shock absorber.

[0020] The installation of the shock absorber facilitates the movement of the fixing clamp, which allows the second protective pad to match the body of the molten steel ladle. This causes the spring to rebound, resulting in a tighter seal between the second protective pad and the second slot.

[0021] The beneficial effects of this utility model are as follows: the corresponding mechanism allows workers to open the cover without manual removal, enabling the cover to be opened quickly and safely, thereby significantly shortening the removal time, reducing labor intensity, and also reducing potential safety hazards caused by improper manual operation.

Detailed Implementation

[0028] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] like Figure 1 and Figure 2 As shown, a fixing mechanism 2 is installed on the steel tank body 1. The fixing mechanism 2 includes a fixing plate 201. The cover plate body 101 is installed on the fixing plate 201. Several fixing clips 202 are provided on the outside of the steel tank body 1. The fixing clips 202 are matched with the steel tank body 1. Several sliding strips 203 are slidably installed inside the fixing plate 201. The fixing clips 202 are connected to the sliding strips 203. A first gear 204 is provided on the fixing plate 201.

[0030] The installation of the fixing plate 201 facilitates the fastening with the molten steel ladle body 1, thus ensuring a secure fixation. The installation of the fixing clip 202 facilitates the closing action with the molten steel ladle body 1, ensuring that the cover plate body 101 covers the molten steel ladle body 1 for heat preservation while also ensuring a tight connection with the molten steel ladle body 1. The installation of the sliding bar 203 facilitates the control of the movement of the fixing clip 202, enabling the fixing clip 202 to clamp the molten steel ladle body 1. The installation of the first gear 204 facilitates the rotational movement, and when the first gear 204 moves, it facilitates the sliding action of the limit rod 205.

[0031] A limiting rod 205 is fixedly installed on the sliding bar 203. The limiting rod 205 passes through the first gear 204, and a limiting groove matching the limiting rod 205 is carved on the first gear 204.

[0032] The installation of the limiting rod 205 facilitates the sliding action according to the rotation of the first gear 204, thereby facilitating the control of the sliding action of the sliding bar 203.

[0033] A support rod 206 is installed on the fixed plate 201, a first gear 204 is rotatably installed on the support rod 206, and a second gear 207 is provided on the fixed plate 201.

[0034] The support rod 206 provides support, thus facilitating the installation of the first gear 204 and enabling it to rotate. The second gear 207, on the other hand, drives the first gear 204 to rotate during rotation.

[0035] The second gear 207 meshes with the first gear 204, and a bracket 208 is fixedly installed on the fixing plate 201.

[0036] The bracket 208 provides support, protects the mechanism on the fixing plate 201, and facilitates the installation of the motor 209.

[0037] An electric motor 209 is mounted on the bracket 208, and the electric motor 209 passes through the bracket 208 and is connected to the second gear 207.

[0038] The installation of the electric motor 209 facilitates the conversion of electrical energy into mechanical energy, thereby facilitating the rotation of the second gear 207.

[0039] like Figure 2 and Figure 3 As shown, the auxiliary mechanism 3 is installed on the fixed mechanism 2. The auxiliary mechanism 3 includes a first protective pad 301, which is installed on the fixed clamp 202. A first slot matching the first protective pad 301 is cut on the steel tank body 1.

[0040] The installation of the first protective pad 301 facilitates the buffering of the contact force on the molten steel tank body 1 when the fixing clip 202 comes into contact with it, making it easier for the fixing clip 202 to be more firmly engaged with the molten steel tank body 1.

[0041] A pair of shock absorbers 302 are fixedly installed on the fixing clamp 202. A second protective pad 303 is installed on the shock absorber 302. A second slot matching the second protective pad 303 is cut on the steel ladle body 1. A spring 304 is installed on the outer sleeve of the shock absorber 302.

[0042] The installation of the shock absorber 302 facilitates the movement of the fixing clip 202 to match the second protective pad 303 with the steel ladle body 1, thereby causing the spring 304 to rebound, which can make the second protective pad 303 and the second slot close more tightly.

[0043] During use, when the cover plate body 101 needs to be opened, the motor 209 can drive the second gear 207 to rotate. The rotation of the second gear 207 will drive the first gear 204. Therefore, when the first gear 204 rotates, it will drive the limiting rod 205 to slide in the limiting groove. When the limiting rod 205 slides, it will push the fixing clamp 202 to slide in the fixing plate 201. As a result, the sliding bar 203 will drive the fixing clamp 202 away from the steel tank body 1. When the fixing plate 201 is away from the steel tank body 1, the first protective pad 301 and the second protective pad 303 will disengage from the steel tank body 1. Therefore, the steel tank body 1 is no longer fixed. Thus, the fixing mechanism 2 can be pulled to remove the cover plate body 101 from the steel tank body 1, so that the operator does not need to remove it manually.

[0044] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
