The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0024] like Figures 1 to 6 As shown, this embodiment provides a long-axis industrial television, including a mounting frame 10, a driving device 20 mounted on the mounting frame 10, a baffle device 30 fixed on the mounting frame 10, and a camera body 40 fixed on the driving device 20. Under the action of the driving device 20, the camera body 40 can move along the mounting frame 10, and the camera body 40 pushes against the baffle device 30 and then inserts into the blast furnace. The camera body 40 can monitor the combustion conditions or workpiece heating conditions in the blast furnace in real time. When maintenance is required, the driving device 20 moves the camera body 40 out of the baffle device 30, and the baffle device 30 is closed to block the blast furnace to prevent high-temperature dust in the furnace from escaping. At the same time, the driving device 20 can lock the camera body 40 moved out of the baffle device 30 on the mounting frame 10.

[0025] like Figure 1 As shown, the mounting frame 10 includes a guard plate 110 fixed on the side wall of the blast furnace and a travel frame 120 installed on the side of the guard plate 110 away from the blast furnace. The guard plate 110 is provided with a through hole connected to the inside of the blast furnace, and the through hole is used to allow the camera body 40 to enter the blast furnace. The travel frame 120 is preferably a rectangular empty frame structure, the travel frame 120 is vertically fixed on the guard plate 110, and a travel groove 122 is opened on the travel frame 120, and the travel groove 122 is opened on the side of the travel frame 120 facing the through hole, and a sealing strip 123 is fixedly installed on the notch of the travel groove 122, and the sealing strip 123 can block and block the notch of the travel groove 122, and a plurality of cooling air pipes 121 are fixedly installed on the side of the travel frame 120 away from the guard plate 110, and the cooling air pipes 121 are connected to the compression system, and cooling gas can be injected into the travel frame 120 through the compression system. The sealing of the sealing strip 123 can reduce the loss of cooling gas in the travel frame 120, and the driving device 20 is fixedly installed inside the travel frame 120, and the cooling gas can cool and protect the driving device 20, and the baffle device 30 covers the through hole and is installed on the guard plate 110.

[0026] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the driving device 20 includes a rodless cylinder 210 installed in the travel frame 120, a linkage block 220 fixed on the piston of the rodless cylinder 210, a travel assembly 230 connected to the linkage block 220, a hook block 240 and a locking assembly 250 installed in the travel frame 120.

[0027] The cylinder body of the rodless cylinder 210 is fixed at both ends of the travel frame 120, and the piston of the rodless cylinder 210 can slide along the cylinder body. After the rodless cylinder 210 is started, the piston can drive the linkage block 220 to slide. The linkage block 220 extends to the outside of the travel frame 120 through the travel groove 122. The camera body 10 is fixed on the linkage block 220 extending out of the travel frame 120. Driven by the rodless cylinder 210, the camera body 40 can move in the direction of approaching or moving away from the guard plate, and the guard plate 110 can be inserted or removed during the movement of the camera body 40. The stroke assembly 230 includes a track rod 231 fixedly installed in the stroke frame 120 and a stroke block 232 slidably clamped on the track rod 231. The track rod 231 is arranged parallel to the rodless cylinder 210, and the stroke block 232 is fixed on the linkage block 220. The stroke block 232 supports the linkage block 220 and the camera body 40. The stroke block 232 can share the pressure of the linkage block 220 and the camera body 40 on the piston of the rodless cylinder 210, thereby improving the service life of the rodless cylinder 210. The track rod 231 and the stroke block 232 also limit the movement direction of the linkage block 220 to avoid deviation in the moving direction of the linkage block 220 and scratches on the cylinder body of the rodless cylinder 210.

[0028] like Figure 2 and Figure 3As shown, the hook block 240 is fixed on the side of the linkage block 220 away from the camera body 40, and the end of the hook block 240 is a hook-shaped structure approximately in the shape of a right triangle, and the hook-shaped end of the hook block 240 is arranged toward the end away from the guard plate 110. The locking assembly 250 is arranged corresponding to the hook-shaped end of the hook block 240, and the locking assembly 250 includes an interlaced block 251 fixed in the travel frame 120, a locking cylinder 252 installed in the travel frame 120, a locking block 253 fixed on the locking cylinder 252, and a yielding wheel 254 installed on the locking block 253. The insertion block 251 is arranged at the end of the travel frame 120, and a through groove is opened on the insertion block 251, and the through groove penetrates the insertion block 251. The cylinder body of the locking cylinder 252 is fixedly installed on the travel frame 120, and the locking cylinder 252 is arranged corresponding to the through direction of the through groove, that is, the locking cylinder 252 can be extended and retracted along the through direction of the through groove, and the locking block 253 is fixed on the piston rod of the locking cylinder 252. The locking block 253 can be slidably inserted in the through groove of the insertion block 251. The locking cylinder 252 can drive the locking block 253 to slide in the through groove of the insertion block 251. The locking block 253 is arranged corresponding to the hook-shaped end of the hook block 240. Under the drive of the locking cylinder 252, the locking block 253 can pass through the through groove of the insertion block 251 and extend into the hook inner bend of the hook block 240, thereby preventing the hook block 240 from moving toward the guard plate 110. The yield wheel 254 is installed on the end of the locking block 253 away from the locking cylinder 252. When the hook block 240 moves, the inclined surface of the hook block 240 can squeeze and push the yield wheel 254. When the locking cylinder 252 releases the support against the locking block 253, the hook block 240 can push the yield wheel 254 with the help of its own inclined surface during the movement. The yield wheel 254 converts the sliding friction between the locking block 253 and the hook block 240 into rolling friction, thereby facilitating the movement of the hook block 240. When the hook block 240 moves into place, the locking cylinder 252 is inflated, the locking block 253 and the yield wheel 254 move, and the yield wheel 254 is pushed to the inside of the hook bend of the hook block 240, so that the yield wheel 254 can limit the hook block 240.

[0029] like Figure 1 , Figure 5 , Figure 6 As shown, the baffle device 30 includes a cover tube 310 installed on the guard plate 110 , a bogie 320 inserted into the cover tube 310 , and a baffle 330 fixed on the bogie 320 .

[0030] The cover tube 310 covers the through hole on the protective plate 110. Preferably, the cover tube 310 is connected with a cooling pipe 311, and refrigerant gas can be input into the cover tube 310 through the cooling pipe 311 to cool and protect the camera body 40 extending into the through hole. There are two sets of bogies 320, which are arranged on both sides of the opening of the cover cylinder 310. The bogies 320 are of U-shaped structure. The rods on both sides of the bogies 320 are arranged on the outside of the cover cylinder 310, and the middle rod of the bogies 320 passes through the cover cylinder 310. There are two baffles 330, which are fixedly installed on the middle rod of the bogies 320. The baffles 330 are of fan-shaped structure. After the two baffles 330 are connected, they can form a round pancake structure to block the opening of the cover cylinder 310. A tension spring 340 is connected between the rods on both sides of the two bogies 320. After the baffles 330 are flipped, the tension spring 340 can be pulled to stretch. With the help of elastic potential energy, the baffles 330 can be reset to the initial state of blocking the opening of the cover cylinder 310.

[0031] When the above-mentioned long-axis industrial television is in use, the mounting frame 10 is installed on the side wall of the blast furnace. When the situation in the blast furnace needs to be monitored in real time, the piston shaft of the locking cylinder 252 is retracted, and the locking block 253 and the yield wheel 254 are moved out from the hook bend of the hook block 240. The rodless cylinder 210 is used to drive the linkage block 220 to move in the stroke frame 120. During the movement, the linkage block 220 can drive the hook block 240 and the camera body 40 to move toward the cover tube 310. The camera body 40 pushes the baffle 330 to flip and open the opening of the cover tube 310. The camera body 40 enters the blast furnace through the through holes of the cover tube 310 and the guard plate 110. The camera body 40 extends into the blast furnace. When the camera body 40 needs maintenance after monitoring, The inflation state of the locking cylinder 252 is released, and the rodless cylinder 210 is used to move the camera body 40. When the camera body 40 is moved out of the cover tube 310, after the camera body 40 is withdrawn, under the action of the tension spring 340, the two bogies 320 are relatively folded, thereby driving the baffle 330 to automatically merge, and the cover tube 310 is blocked to prevent the escape of dust and heat. When the linkage block 220 moves into place, the inclined surface of the hook block 240 pushes against the yield wheel 254 and the locking block 253, and the locking block 253 is retracted into the through groove of the interlaced block 251. When the hook block 240 moves into place, the locking cylinder 252 is inflated, so that the yield wheel 254 and the locking block 253 extend into the hook bend of the hook block 240, completing the push-back locking operation.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
