Description

Technical Field

[0001] This utility model belongs to the field of metallurgical steel rolling technology, and specifically relates to a structure for preventing billet displacement in a bar and wire hot conveying traveling machine. Background Technology

[0002] In metallurgical enterprises, processes such as sintering, ironmaking, steelmaking, and rolling are involved. Especially in the steelmaking and rolling processes, the finished products (square billets, plates, and round bars) need to be transported using relatively stable conveying devices to enter the next process for other production. In order to ensure that the temperature of the hot steel billet meets the rolling requirements, the hot steel billet is first passed into a heating furnace for heating and homogenization during the hot steel billet conveying process, and finally sent to the rolling mill for rolling. However, during the movement of the hot steel billet with the roller conveyor, a large amount of heat is lost from the hot steel billet, which requires the heating furnace to provide a large amount of heat for the hot steel billet. This leads to the heating furnace consuming a large amount of gas to generate heat, making it difficult to reduce the cost of heating furnace consumption.

[0003] A search of Chinese patents revealed a heat preservation device for hot conveying rollers, with publication number CN220387480U. This device includes an outer casing and an inner casing, with an insulation layer between them. End plates are commonly installed on the end walls of both the outer and inner casings, and the insulation layer is located between the end plates. A set of base plates is commonly installed at the bottom of both the outer and inner casings, with the bottom walls of the end plates fixedly connected to the base plates. The insulation layer is located above the base plates. This device effectively reduces heat loss from steel billets, increases the hot conveying rate of steel billets, and reduces the consumption cost of the heating furnace. However, its overall protective cover is relatively large, making transportation and installation relatively inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for preventing billet displacement in a bar and wire hot conveying machine. Its advantages are that the bellows heat insulation cover can be easily folded during transportation and placement, and it can prevent the billet from shifting left and right during transportation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a billet displacement prevention structure for a bar and wire hot conveying machine, comprising a conveying roller table, wherein a first mounting frame and a second mounting frame are detachably installed at both ends of the top of the conveying roller table, and a bellows heat insulation cover for heat insulation is installed between the first mounting frame and the second mounting frame, wherein an anti-deviation mechanism is installed on the conveying roller table between the gaps of the conveying rollers, and two lugs are installed at one end of the conveying roller table, wherein a feeding guide roller for guiding the billet feeding is rotatably installed between the two lugs.

[0006] The above technical solution is adopted: by setting up a bellows heat insulation cover, the heat loss of steel billet can be reduced and the hot delivery efficiency of steel billet can be improved. In addition, the bellows heat insulation cover can be easily folded and transported before installation, reducing the space occupied, and it is also easy to unfold during installation. The anti-deviation mechanism can prevent the steel billet from shifting during the hot delivery process.

[0007] The present invention is further configured such that the accordion heat insulation cover is made of heat-resistant stainless steel.

[0008] The above technical solution uses a heat-resistant stainless steel bellows heat insulation cover that can reflect most of the heat radiation, directly reflecting the heat from the heat source back. It also has a large heat capacity and good thermal conductivity, which can quickly diffuse the locally absorbed heat to the entire cover.

[0009] The present invention is further configured such that the anti-deviation mechanism includes a mounting frame, a support roller, a side mounting plate, and an anti-deviation roller. Two mounting frames are installed on the bottom inner wall of the conveyor roller platform between the gaps of its conveyor rollers. A support roller is rotatably connected between the two mounting frames. A side mounting plate that cooperates with the two mounting frames is installed on the side inner wall of the conveyor roller platform between the gaps of its conveyor rollers. An anti-deviation roller that cooperates with the support roller is rotatably connected between the side mounting plate between the gaps of the conveyor rollers and its adjacent mounting frame.

[0010] The above technical solution is adopted: the support roller is used in conjunction with the conveying roller of the conveying roller table to heat-transfer the steel billet, and the anti-deviation rollers on both sides of the support roller can limit the steel billet from shifting in the left and right directions during the transportation process.

[0011] The present invention is further configured such that the anti-deviation roller is inclined, and the support roller and the anti-deviation rollers on both sides are V-shaped as a whole.

[0012] The above technical solution involves tilting the anti-deviation roller and placing it on the side of the support roller, which can limit the steel billet transported by the support roller and prevent the steel billet from shifting to the left or right.

[0013] The present invention is further configured such that mounting cylinders are fixedly installed at the four corners of the top of the conveying roller table, the top of the mounting cylinder is provided with a screw hole, the outer wall of the mounting cylinder is provided with a notch communicating with the screw hole, and mounting posts that can pass through the screw hole and the notch are installed on the side of the first mounting frame and the second mounting frame that are far apart from each other. The screw hole is threadedly connected to a clamping stud that can press and limit the mounting post.

[0014] Using the above technical solution: When installing the first mounting frame, the second mounting frame, and the bellows heat insulation cover, the first mounting frame and the second mounting frame are placed at the top two ends of the conveyor roller table, and the bellows heat insulation cover is unfolded. Then, the mounting posts on the first mounting frame and the second mounting frame are passed through the screw holes and notches on the corresponding mounting cylinders. Afterwards, the mounting posts are pressed by connecting the screw holes with the threaded clamping studs, thereby completing the installation of the first mounting frame and the second mounting frame, and fixing the bellows heat insulation cover.

[0015] The present invention is further configured such that the top front side and the top rear side of the conveying roller table are integrally provided with flanges, and positioning holes are provided on the flanges. Positioning posts that can pass through the positioning holes are fixedly connected to the bottom of the first mounting frame and the second mounting frame.

[0016] By adopting the above technical solution, the positioning holes and positioning posts can facilitate the installation and positioning of the first and second mounting frames during installation.

[0017] The present invention is further configured such that an annular guide groove is provided on the feed guide roller.

[0018] Using the above technical solution: When the steel billet is fed, it enters the conveying roller table through the guide chute of the feed guide roller.

[0019] The present invention is further configured such that the guide trough is V-shaped as a whole.

[0020] The above technical solution uses a V-shaped guide chute, which allows the transported steel billets to pass through the anti-deviation mechanism relatively stably.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model can reduce heat loss from steel billets and improve the efficiency of hot billet delivery by setting up a bellows heat insulation cover. In addition, the bellows heat insulation cover can be easily folded and transported before installation, reducing the space occupied.

[0022] 2. This utility model, by combining the support roller with the anti-deviation rollers inclined on both sides, can limit the left and right deviation during the anti-deviation transportation process, so as to ensure the relatively stable transportation of the steel billet.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: refer to Figure 1 , Figure 3 , Figure 6 A structure for preventing billet displacement in a bar and wire hot conveying machine includes a conveying roller table 1. A first mounting frame 2 and a second mounting frame 3 are detachably installed at both ends of the top of the conveying roller table 1. A bellows heat insulation cover 4 for heat insulation is installed between the first mounting frame 2 and the second mounting frame 3. Two lugs 17 are installed at one end of the conveying roller table 1. A feed guide roller 18 for guiding the billet feeding is rotatably installed between the two lugs 17.

[0027] By setting up the bellows heat insulation cover 4, the heat loss of the steel billet can be reduced and the hot delivery efficiency of the steel billet can be improved. In addition, the bellows heat insulation cover 4 can be easily folded and transported before installation, reducing the space occupied, and it is also easy to unfold during installation.

[0028] The roller frame of the conveyor roller table 1 is U-shaped, and the conveyor roller is rotatably installed inside the U-shaped roller frame. The first mounting frame 2, the second mounting frame 3, and the bellows heat insulation cover 4 are installed on the roller frame of the conveyor roller table 1.

[0029] refer to Figure 3 The accordion heat shield 4 is made of heat-resistant stainless steel.

[0030] The heat-resistant stainless steel bellows heat shield 4 can reflect most of the heat radiation, directly reflecting the heat from the heat source back. It also has a large heat capacity and good thermal conductivity, which can quickly diffuse the locally absorbed heat to the entire shield.

[0031] refer to Figure 1 , Figure 4Mounting cylinders 10 are fixedly installed at the four corners of the top of the conveyor roller table 1. The top of the mounting cylinder 10 is provided with screw holes 11, and the outer wall of the mounting cylinder 10 is provided with notches 12 that communicate with the screw holes 11. Mounting posts 13 that can pass through the screw holes 11 and notches 12 are installed on the side of the first mounting frame 2 and the second mounting frame 3 that are far apart from each other. The screw holes 11 are threadedly connected to clamping screws 14 that can clamp and limit the mounting posts 13.

[0032] When installing the first mounting frame 2, the second mounting frame 3, and the bellows heat insulation cover 4, place the first mounting frame 2 and the second mounting frame 3 at the top ends of the conveyor roller table 1 respectively, unfold the bellows heat insulation cover 4, and then pass the mounting posts 13 on the first mounting frame 2 and the second mounting frame 3 through the screw holes 11 and notches 12 on the corresponding mounting cylinders 10. Then, by threading the clamping studs 14 into the screw holes 11, the mounting posts 13 are clamped, thereby completing the installation of the first mounting frame 2 and the second mounting frame 3, and fixing the bellows heat insulation cover 4.

[0033] refer to Figure 1 , Figure 4 and Figure 5 The top front and rear sides of the conveyor roller table 1 are integrally provided with flanges 20, and positioning holes 15 are provided on the flanges 20. The bottom of the first mounting frame 2 and the second mounting frame 3 are fixedly connected with positioning posts 16 that can pass through the positioning holes 15.

[0034] When installing the first mounting frame 2 and the second mounting frame 3, the positioning hole 15 and the positioning post 16 cooperate to facilitate the installation and positioning of the first mounting frame 2 and the second mounting frame 3.

[0035] Brief description of the usage process: The first mounting frame 2 and the second mounting frame 3 are respectively installed at the top two ends of the conveyor roller table 1, and the bellows heat insulation cover 4 is unfolded. The bellows heat insulation cover 4 blocks the space above the conveyor roller table 1, which can reduce the heat loss during the transportation of steel billets and play a heat insulation role.

[0036] Example 2: refer to Figure 1 , Figure 2 A structure for preventing billet displacement in a bar and wire hot conveying machine includes a conveying roller table 1, on which an anti-deviation mechanism 5 is installed between the conveying rollers.

[0037] refer to Figure 5The anti-deviation mechanism 5 includes a mounting frame 6, a support roller 7, a side mounting plate 8, and an anti-deviation roller 9. Two mounting frames 6 are installed on the bottom inner wall of the conveyor roller platform 1 between the gaps of its conveyor rollers. The support roller 7 is rotatably connected between the two mounting frames 6. The side mounting plate 8 that cooperates with the two mounting frames 6 is installed on the side inner wall of the conveyor roller platform 1 between the gaps of its conveyor rollers. The anti-deviation roller 9 that cooperates with the support roller 7 is rotatably connected between the side mounting plate 8 located between the gaps of the conveyor rollers and its adjacent mounting frame 6.

[0038] The support roller 7 is used in conjunction with the conveying roller of the conveying roller table 1 to heat-transfer the steel billet. The anti-deviation rollers 9 on both sides of the support roller 7 can limit the steel billet from shifting in the left and right directions during the transportation process.

[0039] refer to Figure 5 The anti-deviation roller 9 is set at an angle, and the support roller 7 and the anti-deviation rollers 9 on both sides are V-shaped as a whole.

[0040] The anti-deviation roller 9 is tilted and located on the side of the support roller 7, which can limit the steel billet transported by the support roller 7 and prevent the steel billet from shifting to the left or right.

[0041] refer to Figure 1 , Figure 6 The feed guide roller 18 has an annular guide groove 19, which is V-shaped in general.

[0042] When the steel billet is fed, it enters the conveying roller table 1 through the guide groove 19 of the feed guide roller 18, so that the steel billet can pass through the anti-deviation mechanism 5 relatively stably.

[0043] The height of the bottom inner wall of the guide trough 19 is on the same horizontal line as the top height of the conveying roller of the conveying roller table 1 and the top height of the support roller 7.

[0044] Brief description of the usage process: The transported steel billet is guided by the feed guide roller 18 and enters the conveyor roller table 1. Then, the steel billet is supported and conveyed by the conveyor roller and support roller 7 on the conveyor roller table 1. The anti-deviation rollers 9 on both sides of the support roller 7 can limit the displacement of the steel billet in the left and right directions, so that the steel billet is transported relatively stably and avoids deviation.

[0045] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
