Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A transmission structure of a walking beam heating furnace, comprising a frame 1, a stepping collecting mechanism 2 is provided on one side of the frame 1, a heat dissipation component 3 is provided on one side of the frame 1, and a circulation component 4 is provided on one side of the stepping collecting mechanism 2;

[0031] The stepping collection mechanism 2 includes a fixed plate 201, a motor 202, a rotating column 203, a transmission column 204, a belt 205, a fixed ring 206, a pushing block 207, an extension plate 208, a stepping beam 209 and a collection box 210. The multiple fixed plates 201 are fixedly connected to one side of the frame 1, the motor 202 is bolted to one side of the frame 1, the rotating column 203 is fixedly connected to the output end of the motor 202, the transmission column 204 is rotatably connected to one side of the frame 1, the belt 205 is arranged on the outer wall of the rotating column 203 and the transmission column 204, the multiple fixed rings 206 are respectively fixedly connected to the outer walls of the rotating column 203 and the transmission column 204, the multiple pushing blocks 207 are respectively hinged to one side of the multiple fixed rings 206, the multiple extension plates 208 are respectively fixedly connected to one side of the multiple pushing blocks 207, the multiple stepping beams 209 are respectively fixedly connected to the top of the multiple extension plates 208, and the collection box 210 is arranged on one side of the frame 1.

[0032] Specifically, Figure 1 As shown, a plurality of extension columns 5 are fixedly connected to one side of the frame 1 , and a limit plate 6 is hinged to the outer wall of the extension column 5 .

[0033] Specifically, Figure 1 As shown, a protrusion 7 is fixedly connected to the top of the walking beam 209, and the number of the protrusions 7 is several and evenly arranged.

[0034] Specifically, Figure 2 As shown, one side of the pushing block 207 is fixedly connected to the supporting block 10 .

[0035] Specifically, Figure 1 As shown, a hook ring 11 is fixedly connected to one side of the collection box 210 .

[0036] When in use, the motor 202 is started to rotate the rotating column 203, and then the transmission column 204 is driven to rotate through the belt 205. When the rotating column 203 and the transmission column 204 rotate, the fixed ring 206 is synchronously driven to rotate, and then the push block 207 and the extension plate 208 are rotated and displaced, so that the stepping beam 209 is raised and lowered in a circle according to the rotation direction of the fixed ring 206. When the stepping beam 209 is raised, it is higher than the fixed plate 201, and can form a step to move the blank. When the blank contacts with oxygen in the air during the heating process, a layer of oxide is formed on its surface. After continuous lifting and falling, the oxide will fall off, and the residue after falling will fall into the collection box 210, and the fixing ring 206 and the pushing block 207 are arranged under the fixing plate 201, and will not be affected by the oxide residue and can be used continuously. Subsequent staff can pull out the collection box 210 through the hook ring 11 for easy cleaning. The extension column 5 and the limiting plate 6 are used in conjunction to limit the collection box 210. The protrusion 7 can increase the friction between the blank and the stepping beam 209, making the blank more stable during the movement, and the support block 10 can increase the stability of the pushing block 207.

[0037] Specifically, Figure 3 As shown, the heat dissipation component 3 includes a water tank 301, a support plate 302, a water pump 303, a transmission pipe 304, a first hose 305 and a transmission hole 306. The multiple water tanks 301 are respectively fixedly connected to the two sides of the frame 1, the multiple support plates 302 are respectively fixedly connected to the two sides of the frame 1, the multiple water pumps 303 are respectively arranged on the top of the multiple support plates 302, the multiple transmission pipes 304 are respectively arranged on one side of the multiple water pumps 303, the multiple first hoses 305 are respectively arranged on one side of the multiple transmission pipes 304, and the multiple transmission holes 306 are respectively opened in the inside of the multiple stepping beams 209.

[0038] Specifically, Figure 3 As shown, the circulation component 4 includes a second hose 401 and an injection pipe 402, and the multiple second hoses 401 are respectively arranged at the bottom of the multiple stepping beams 209, and the multiple injection pipes 402 are respectively arranged on one side of the multiple second hoses 401, and the other sides of the multiple injection pipes 402 are respectively fixedly connected to one side of the water tank 301.

[0039] Specifically, Figure 1 As shown, a water injection pipe 8 is fixedly connected to the top of the water tank 301 , and a dust cap 9 is clamped on the top of the water injection pipe 8 .

[0040] When in use, the staff injects water into the water tank 301 through the water injection pipe 8. When the walking beam 209 starts to work, the water pump 303 is started synchronously to pump out the water in the water tank 301, and the water is injected into the transmission hole 306 after passing through the transmission pipe 304 and the first hose 305, so as to dissipate heat for the walking beam 209 in use to prevent it from being damaged by overheating due to continuous contact with the heated blank. The residual water flow after passing through the transmission hole 306 can return to the water tank 301 through the second hose 401 and the injection pipe 402, so as to facilitate reuse and improve heat dissipation efficiency.

[0041] By adopting the above technical solution, a problem of an existing hydraulically driven stepping mechanism of a walking-beam heating furnace is solved. When the blank is in use and comes into contact with oxygen in the air during the heating process, a layer of oxide will be formed on its surface. In the process of continuous stepping, the blank will continue to rise and fall, and then the oxide will fall off. If it is not collected, it will continue to accumulate and affect the parts of the stepping mechanism.

[0042] Working principle: When the present application is in use, the motor 202 is started to rotate the rotating column 203, and then the transmission column 204 is driven to rotate through the belt 205. When the rotating column 203 and the transmission column 204 rotate, the fixed ring 206 is synchronously driven to rotate, and then the push block 207 and the extension plate 208 are rotated and displaced, so that the stepping beam 209 is circularly raised and lowered according to the rotation direction of the fixed ring 206. When the stepping beam 209 is raised, it is higher than the fixed plate 201, and can form a step to move the blank. When the blank contacts with oxygen in the air during the heating process, a layer of oxide will be formed on its surface. After continuous rising and falling, the oxide will fall off, and the residue after falling will It falls into the collection box 210, and the fixing ring 206 and the pushing block 207 are arranged under the fixing plate 201, and will not be affected by the oxide residue and can be used continuously. The water pump 303 is started to pump out the water in the water tank 301, and the water is injected into the transmission hole 306 after passing through the transmission pipe 304 and the first hose 305, so as to dissipate heat for the stepping beam 209 in use to prevent it from being damaged by overheating due to continuous contact with the heated blank. The residual water flow after passing through the transmission hole 306 can return to the water tank 301 through the second hose 401 and the injection pipe 402, so as to facilitate reuse and improve the heat dissipation efficiency. The subsequent staff can pull out the collection box 210 through the hook ring 11 for easy cleaning.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
