Description

Technical Field

[0001] This utility model relates to the field of heating furnace protection technology, specifically a safety protection device for steel heating furnaces. Background Technology

[0002] Steel heating furnaces are equipment used in the steel production process to heat steel billets or finished steel products. During operation, steel is directly fed into the furnace through the filling inlet, the furnace door is closed, and the steel is heated. After heating, the steel is removed through the discharge outlet on the other side. In existing technology, for safety reasons, a protective structure is typically installed on the outside of the furnace door to prevent personnel from approaching and causing safety hazards when the furnace door is opened for filling. However, the fixed protective structure in existing technology is always located at the furnace door. High temperatures can affect the protective structure, and the structure itself also maintains a high temperature. Therefore, if someone accidentally touches it, there is still a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection device for steel heating furnaces to solve the problem of high temperature hazards in existing protection structures.

[0004] To achieve the above objectives, the basic solution provided by this utility model is: a safety protection device for a steel heating furnace, comprising:

[0005] A protective installation support assembly, comprising a furnace door, a first side plate and a second side plate disposed on both sides of the furnace door;

[0006] The linkage protection assembly includes a concave frame fixed inside the first side plate, a protective door inserted into the concave frame, a first rack fixed to the surface of the protective door, a first gear meshing with the first rack, a round shaft connected to the first gear, a second gear fixed to the round shaft, a second rack connected to both sides of the furnace door, a third gear meshing with the second rack, a rotating shaft connected to the third gear, and an L-shaped rod connected to the rotating shaft.

[0007] Furthermore, a heating furnace body is provided on the side of the furnace door, and a cylinder is provided on the top of the heating furnace body, with the piston rod of the cylinder connected to the furnace door.

[0008] Furthermore, the heating furnace body is provided with a packing inlet, and the protective door is provided with a packing port.

[0009] Furthermore, the L-shaped rod is fixed to the outer wall of the heating furnace body, and the third gear rotates via a shaft.

[0010] Furthermore, a first baffle and a second baffle are fixed on the circular shaft, and the first side plate is located between the first baffle and the second baffle.

[0011] Furthermore, it also includes an adjustment assembly, which includes a threaded rod penetrating the protective door partition and a triangular disc fixed to the top of the threaded rod.

[0012] Furthermore, the adjustment assembly also includes a baffle that passes through the threaded rod and a bolt connected to the threaded rod, with the two bolts pressing the baffle together.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. Through the cooperation of the protective installation support components and the linkage protective components, the protective structure is linked with the furnace door during use. When the furnace door is opened and the filling is applied, the protective structure automatically falls and a filling port is reserved. When the furnace door is closed, the protective structure moves upward in linkage. This way, the protective door stays in the furnace door position for a short time, avoiding the protective door from being constantly at a high temperature. In case of accidental contact, it will prevent workers from being burned and improve the safety of use.

[0015] 2. The size of the filling port can be adjusted by the set adjustment components, which ensures the smooth filling of the packing while protecting the device, making it convenient to use. Attached Figure Description

[0023] The present invention will be further described in detail below through specific embodiments.

[0024] like Figures 1 to 6 As shown: A safety protection device for a steel heating furnace includes a protective installation support assembly and a linkage protection assembly. The protective installation support assembly is used to support the installation of the linkage protection assembly. Specifically, the protective installation support assembly includes a furnace door 14, a first side plate 15 and a second side plate 16 on both sides of the furnace door 14. A heating furnace body 11 is provided on the side of the furnace door 14, and a cylinder 13 is provided at the top of the heating furnace body 11. The piston rod of the cylinder 13 is connected to the furnace door 14. A filling inlet 12 is provided on the heating furnace body 11, and a filling port 211 is provided on the protective door 21.

[0025] In practical use, steel is fed in through the filling inlet 12, and the cylinder 13 drives the furnace door 14 to move down to cover the filling inlet 12. The first side plate 15 and the second side plate 16 provide installation support for the linkage protection components, thereby completing the linkage protection.

[0026] The linkage protection component is used for the flexible use of the protective door 21 to improve the safety of use. Specifically, the linkage protection component includes a concave frame 23 fixed inside the first side plate 15, a protective door 21 inserted into the concave frame 23, a first rack 22 fixed on the surface of the protective door 21, a first gear 24 meshing with the first rack 22, a round shaft 25 connected to the first gear 24, a second gear 26 fixed to the round shaft 25, a second rack 27 connected to both sides of the furnace door 14, a third gear 210 meshing with the second rack 27, a rotating shaft 29 connected to the third gear 210, and an L-shaped rod 28 connected to the rotating shaft 29.

[0027] In practical use, as the furnace door 14 moves upward, the second rack 27 is also driven to move upward. At this time, the second rack 27 drives the third gear 210 to rotate through the rotating shaft 29. The second gear 26 is also driven. The second gear 26 is connected to the first gear 24 through the round shaft 25, so the first gear 24 is also driven. The first gear 24 meshes with the first rack 22, so the first rack 22 also moves synchronously, thereby driving the protective door 21 to move downward. When the furnace door 14 moves upward and opens, the protective door 21 moves downward synchronously along the concave frame 23. Steel can be put in through the filling port 211. After the steel is put in, when the furnace door 14 moves downward and closes, the protective door 21 moves upward and releases the protection. This provides protection while avoiding the problem of the protective door 21 being too hot.

[0028] Furthermore, a first baffle 241 and a second baffle 242 are fixed on the round shaft 25, and the first side plate 15 is located between the first baffle 241 and the second baffle 242.

[0029] In practical use, the first side plate 15 is located between the first baffle 241 and the second baffle 242, thus ensuring that the round shaft 25 passes through the first side plate 15 and rotates along the hole on the first side plate 15.

[0030] Furthermore, the size of the filling port 211 can be adjusted by the set adjustment components, thereby ensuring the smooth filling while providing protection and facilitating use;

[0031] Specifically, it also includes an adjustment component, which includes a threaded rod 32 that penetrates the partition of the protective door 21 and a triangular disc 31 fixed to the top of the threaded rod 32;

[0032] The adjustment assembly also includes a baffle 33 that passes through the threaded rod 32 and bolts 34 connected to the threaded rod 32, with the two bolts 34 pressing the baffle 33 together.

[0033] In actual use, the user rotates the threaded rod 32 through the triangular disk 31. The threaded rod 32 advances in the threaded hole on the frame of the protective door 21, thereby adjusting the length of the threaded rod 32. When adjusted to the required position, the user uses two bolts 34 to lock the baffle 33 in the required position, thereby controlling the size of the filling port 211.

[0034] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
