Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a protective cover for charging and unloading in a stable annular furnace. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A protective cover for loading and unloading a stable annular furnace includes a furnace wall 1, with a furnace cavity 3 inside the furnace wall 1. The furnace cavity 3 is arranged in multiple rows and columns, and a protective mechanism 2 is installed on the top of the furnace wall 1.

[0026] The protective mechanism 2 includes a protective cover body 201, which is located on the top of the furnace wall 1. The bottom of the protective cover body 201 is in contact with the top of the furnace wall 1. Two symmetrically arranged track grooves 206 are provided in the inner cavity of the protective cover body 201. Four rotating wheels 211 are slidably connected to the inner cavity of the track grooves 206. A protective base 203 is fixedly connected to the top of each rotating wheel 211. Lifting lugs 202 are fixedly connected to the four corners of the top of the protective base 203. The rotating wheels 211 are distributed at the four corners of the bottom of the protective base 203. Protective railings 204 are fixedly connected to both sides of the top of the protective base 203. Support shafts 216 are fixedly connected to the front and back sides of the top of the protective base 203. A limit plate 215 is fixedly connected to the top of the support shaft 216. A protective door stop 205 is rotatably connected to the surface of the support shaft 216. The bottom of the protective cover 205 contacts the top of the protective base 203, and one side of the protective door stop 205 contacts the surface of the protective fence 204. The inner cavities of the protective base 203, the protective fence 204, and the protective door stop 205 are all equipped with protective nets. The operator first places the protective cover body 201 on the top of the furnace wall 1. After the protective cover body 201 is placed, the operator holds the protective door stop 205 and rotates it to open it. Then the operator moves to the top of the protective base 203. After the operator is in position, the operator holds the protective door stop 205 again and rotates it to reset it and readjust it to the closed position. The operator's position can be determined by the combined use of the protective base 203, the protective fence 204, and the protective door stop 205, thus ensuring the safety of the operator during movement.

[0027] Reference Figure 3 and Figure 4 Positioning seats 214 are fixedly connected to the front and back sides of the inner cavity of the track slide 206. The inner cavity of the wheel 211 is provided with a positioning groove 212. The inner cavity of the positioning groove 212 is slidably connected to the surface of the positioning seat 214. The positioning seat 214 is used to position the wheel 211 and prevent the wheel 211 from falling off during the sliding process inside the track slide 206, thereby affecting the stability of the protective base 203 during the movement process.

[0028] Reference Figure 2 , Figure 3 and Figure 6The protective cover body 201 has fixed bases 207 on both the front and back sides. There are several fixed bases 207 arranged in multiple rows. A guide rod 222 is fixedly connected to the bottom of the inner cavity of the fixed base 207. A positioning plate 213 is fixedly connected to one end of the guide rod 222. A positioning ring 210 is fixedly connected to both the front and back sides of the protective base 203. The surface of the positioning plate 213 is inserted into the inner cavity of the positioning ring 210. The fixed bases 207 are used to position the positioning plate 213. The guide rods 222 are used to support the position of the positioning plate 213. When the positioning plate 213 is not under force, it can be stably inserted into the interior of the positioning ring 210. This can fix the position of the protective base 203 and prevent the protective base 203 from shifting during use.

[0029] Reference Figure 6 A spring 223 is slidably connected to the inner cavity of the positioning plate 213. The bottom of the spring 223 is fixedly connected to the bottom of the inner cavity of the fixed seat 207. The spring 223 guides the movement of the positioning plate 213, keeps the positioning plate 213 moving vertically, improves the stability of the positioning plate 213 during movement, and prevents the positioning plate 213 from getting stuck during movement.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The protective base 203 has a support seat 220 fixedly connected to both the front and back sides. A connecting rod 217 is slidably connected to the inner cavity of the support seat 220. A handle 221 is fixedly connected to the top of the connecting rod 217. The bottom of the handle 221 fits against the top of the support seat 220. A movable seat 219 is fixedly connected to one side of the protective door stop 205. The inner cavity of the movable seat 219 is inserted into the surface of the connecting rod 217. The position of the connecting rod 217 is positioned by the support seat 220. When the support seat 220 and the movable seat 219 are at the same horizontal position, the surface of the connecting rod 217 can be inserted into the interior of the movable seat 219, thereby fixing the position of the protective door stop 205 and keeping the protective door stop 205 in a closed state. This prevents the protective door stop 205 from rotating again after it is in place, which would result in the front and back sides of the protective base 203 lacking effective protection, making it easy for command personnel to fall from the front and back sides of the protective base 203.

[0031] Reference Figure 5A limiting ring 218 is fixedly connected to the surface of the connecting rod 217. The bottom of the limiting ring 218 contacts the top of the movable seat 219, and the top of the limiting ring 218 contacts the bottom of the support seat 220. By setting the limiting ring 218, the position of the connecting rod 217 is limited, preventing the connecting rod 217 from detaching from the inside of the support seat 220 during the sliding process, which would cause the connecting rod 217 to fall to the ground without support, affecting the fixing effect of the protective door stop 205.

[0032] Reference Figure 1 and Figure 2 The protective cover body 201 is fixedly connected to the front and back sides of the connecting seat 208. The inner cavity of the connecting seat 208 is threaded with a bolt 209. The surface of the bolt 209 is inserted into the inner cavity of the furnace wall 1. By setting the connecting seat 208, when the surface of the bolt 209 is inserted into the furnace wall 1 and the interior of the connecting seat 208, the position of the protective cover body 201 can be fixed, so that the protective cover body 201 is stably attached to the top of the furnace wall 1, preventing the protective cover body 201 from shifting position during use.

[0033] Working principle: Before the protective cover body 201 is loaded into the annular furnace, the operator first places it on top of the furnace wall 1. The movement of the protective cover body 201 moves the connecting seat 208, causing the bottom of the protective cover body 201 to fit against the top of the furnace wall 1, and one side of the connecting seat 208 to fit against the surface of the furnace wall 1. Bolts 209 are then inserted into the connecting seat 208 and the furnace wall 1 respectively, thus fixing the position of the protective cover body 201 and preventing it from shifting during use. After the protective cover body 201 is placed, the operator pulls the handle 221... Move upwards, and the movement of the handle 221 will move the connecting rod 217, removing it from the inside of the movable seat 219. Then, grasp the protective door stop 205 and rotate it from the closed to the open state. Afterwards, the commanding personnel move to the top of the protective base 203. Once in position, grasp the protective door stop 205 again and rotate it to reset it, readjusting it to the closed state. Then, re-insert the connecting rod 217 into the movable seat 219 to fix the position of the protective door stop 205. To prevent the protective door stop 205 from shifting during use, the protective base 203, protective fence 204, and protective door stop 205 work together to position the commanding personnel. When the commanding personnel's position needs to be adjusted, the positioning plate 213 is pushed downwards. The positioning plate 213 retracts into the fixed seat 207 under force, allowing it to be removed from the positioning ring 210. This releases the fixation of the protective base 203, allowing the operator to move the protective base 203. The movement of the protective base 203 drives the rotating wheel 211 to move on the rail. The sliding groove 206 slides inside to improve the stability of the protective base 203 during movement. At the same time, when the sliding groove 206 slides, the positioning seat 214 slides inside the positioning groove 212, which can restrict the position of the rotating wheel 211 and prevent the rotating wheel 211 from disengaging from the inside of the sliding groove 206 during movement. After the protective base 203 is fully adjusted, the surface of the positioning plate 213 can be re-inserted into the inside of the positioning ring 210 to fix the position of the protective base 203 and prevent the protective base 203 from shaking during use, thereby ensuring the safety of the command personnel during movement.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
