Description

Technical Field

[0001] The present application relates to the technical field of steel processing, and in particular to a multi-line conveying device for steel billets. Background Art

[0002] After heating, the billet needs to be quickly transported to the next processing step, such as hot pressing, to maintain its surface temperature and ensure processing quality. This efficient and continuous production method is particularly important in the field of modern metal processing, not only improving production efficiency but also reducing energy waste.

[0003] Existing steel billet conveying equipment mainly adopts a single steel billet conveying method. This conveying equipment relies on the rotation of the conveying wheel to realize the movement of the steel billet, so as to deliver it to the next processing position. However, the existing single-bill conveying method is difficult to maintain the simultaneous conveying of a large number of steel billets, resulting in low conveying efficiency, which in turn causes the temperature of the steel billet to drop, affecting the smooth progress of the subsequent processing process. Summary of the Invention

[0004] In order to improve the above-mentioned problems, the present application provides a multi-line conveying device for steel billets.

[0005] The present application provides a multi-line steel billet conveying device that adopts the following technical solutions:

[0006] A multi-line conveying device for steel billets, comprising several groups of first conveying mechanisms, second conveying mechanisms, first mounting rails and second mounting rails; the first conveying mechanisms and the second conveying mechanisms are spaced apart along the length direction of the first mounting rail or the second mounting rail; the several first conveying mechanisms on the first mounting rail and the several second conveying mechanisms on the second mounting rail respectively form a conveying line; wherein, the first conveying mechanism comprises a first conveying member, a first driving member and a first driving shaft; the first driving member is parallel to the extension direction of the first mounting rail and is installed at a preset distance, the first driving shaft is connected to the driving end of the first driving member and extends toward the first mounting rail; the first conveying member is installed on the first mounting rail and is pivotally connected to the first driving shaft; the second conveying mechanism comprises a second conveying member, a second driving member and a second driving shaft; the second driving member is installed between the two first driving members; the second driving shaft is connected to the driving end of the second driving member and extends away from the second driving member, extending to the second mounting rail, and the second conveying member is installed on the second mounting rail and is pivotally connected to the second driving shaft.

[0007] By adopting the above technical solution, when conveying the steel billets, the multiple conveying lines formed by the first mounting rail and the second mounting rail synchronously convey the steel billets in multiple groups and lines, so as to improve the conveying efficiency and realize efficient and stable conveying of the steel billets.

[0008] Optionally, at least two conveying lines are provided.

[0009] By adopting the above technical solution, more than two conveying lines can be set up, further increasing the number of conveying lines to further improve the conveying capacity of multi-line conveying.

[0010] Optionally, the first conveying member includes a bearing portion and a rolling portion; the first driving shaft passes through the bearing portion and is pivotally connected to the bearing portion; the rolling portion is mounted on the first driving shaft and rotates with the first driving shaft.

[0011] By adopting the above technical solution, the steel blank contacts the surface of the rolling part. Under the drive of the first drive member or the second drive member, the first drive shaft pivots along the bearing part, so that the rolling part is synchronously driven to rotate, thereby driving the steel blank to move along the surface of the rolling part.

[0012] Optionally, the rolling portion is provided with an annular inner groove, and the steel blank is located in the inner groove.

[0013] By adopting the above technical solution, the moving trajectory of the steel billet will not deviate when it moves, and it will enter another inner groove from one inner groove and move accurately along the path of the inner groove, thereby improving the accuracy of transportation.

[0014] Optionally, the second conveying member has the same structure as the first conveying member.

[0015] By adopting the above technical solution, the steel blanks of another conveyor line can also move along the conveying path of the second conveyor member, and the second conveyor member is staggered with the installation position of the first conveyor member during transportation. Therefore, when the steel blanks need to be lifted, picked up, rolled, etc., it will not affect the transportation of the steel blanks of another conveyor line.

[0016] Optionally, a heat conducting portion is provided below the second driving shaft; the heat conducting portion covers the second driving shaft.

[0017] By adopting the above technical solution, a heat-conducting part is set up to shield the second drive shaft, so that heat is transferred to the second drive shaft. Most of the heat will be transferred to the heat-conducting part, and then transferred to the ground or other installation platform through the heat-conducting part, thereby preventing the second drive shaft from being affected by excessive heat.

[0018] Optionally, the conveying speeds of the first conveying mechanism and the second conveying mechanism are different.

[0019] By adopting the above technical solution, different conveying speeds can be conveniently used to switch the steel billet to other conveying lines using external lifting equipment.

[0020] Optionally, both the first driving member and the second driving member are provided with a heat insulation cover, and both the first driving shaft and the second driving shaft pass through the heat insulation cover and extend outward.

[0021] By adopting the above technical solution, the heat insulation cover is used to separate the first driving member and the second driving member toward the steel billet to prevent the heat emitted from the surface of the steel billet from affecting the first driving member and the second driving member, thereby extending the service life of the first driving member and the second driving member.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When conveying steel billets, the multiple conveying lines formed by the first mounting rail and the second mounting rail simultaneously convey the steel billets in multiple groups and lines, thereby improving the conveying efficiency and achieving efficient and stable steel billet conveying;

[0025] 3. The steel billets on the other conveyor line can also move along the conveying path of the second conveyor member. During the conveying process, the second conveyor member is staggered with the installation position of the first conveyor member. Therefore, when the steel billets need to be lifted, taken, rolled, etc., it will not affect the conveying of steel billets on the other conveyor line.

[0026] 4. The heat conducting part is provided to shield the second drive shaft so that heat is transferred to the second drive shaft. Most of the heat will be transferred to the heat conducting part, and then transferred to the ground or other installation platform through the heat conducting part, which can prevent the second drive shaft from being affected by excessive heat.

Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0036] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0037] The embodiment of the present application discloses a multi-line conveying device for steel billets.

[0038] A multi-line conveying device for steel billets is provided at the discharge end of the heated steel billets, and is used to provide conveying of high-temperature steel billets. The device also provides multi-end and multi-line conveying to improve conveying efficiency and realize efficient and stable conveying of steel billets.

[0039] refer to Figure 1 , including several groups of first conveying mechanisms 1, second conveying mechanisms 2, first mounting rails 3 and second mounting rails 4; several groups of first conveying mechanisms 1 and several groups of second conveying mechanisms 2 are arranged at intervals along the length direction of the first mounting rails 3 or the second mounting rails 4, that is, after a group of first conveying mechanisms 1 are spaced apart by a preset distance, a group of second conveying mechanisms 2 is arranged, and they are spaced apart in sequence until they are transported to a predetermined delivery location. The preset distance of the interval and the number of the first conveying mechanisms 1 and the second conveying mechanisms 2 are determined according to the distance from the actual delivery location to the initial end of the steel billet delivery.

[0040] The plurality of first conveying mechanisms 1 on the first mounting rail 3 and the plurality of second conveying mechanisms 2 on the second mounting rail 4 respectively form a conveying line, so that the steel blanks can be synchronously conveyed through the conveying line of the first conveying mechanism 1 and the conveying line of the second conveying mechanism 2, so as to achieve the effect of multi-section and multi-line conveying, further improving the conveying efficiency, and ensuring the independent operation and mutual coordination between the conveying lines.

[0041] Among them, reference Figure 2 As shown, the first conveying mechanism 1 includes a first conveying member 11, a first driving member 12 and a first driving shaft 13. The first driving member 12 can adopt a driving motor. The first driving member 12 is parallel to the extension direction of the first mounting rail 3 and is installed on the ground or a mounting plane such as a machine at a preset distance. The first driving shaft 13 is connected to the driving end of the first driving member 12 and extends toward the first mounting rail 3. The first conveying member 11 is installed on the first mounting rail 3, and is supported by the first mounting rail 3. It is pivotally connected to the first driving shaft 13, so that the first driving shaft 13 can provide drive to the first conveying member 11 through the first driving member 12. The steel blank is placed on the first conveying member 11. When the rotating end of the first conveying member 11 rotates with the first driving shaft 13, the steel blank moves synchronously to achieve the conveying effect.

[0042] The second conveying mechanism 2 includes a second conveying member 21, a second driving member 22 and a second driving shaft 23. The second driving member 22 is installed between the two first driving members 12, and is set on the same side and at the same distance. The second driving member 22 can use a driving motor. The second driving shaft 23 is connected to the driving end of the second driving member 22 and extends away from the second driving member 22 to the second mounting rail 4. Therefore, the length of the second driving shaft 23 is longer than the first driving shaft 13. After passing through the first mounting rail 3, it extends to the second mounting rail 4. The second conveying member 21 is installed on the second mounting rail 4 and is pivotally connected to the second driving shaft 23, so that the second driving member 22 can drive the rotating end of the second conveying member 21 to contact the steel billet through the second driving shaft 23, and convey the steel billet synchronously.

[0043] When conveying the steel billets, the multiple conveying lines formed by the first mounting rail 3 and the second mounting rail 4 synchronously convey the steel billets in multiple groups and lines, so as to improve the conveying efficiency and realize efficient and stable conveying of the steel billets.

[0044] For further reference, Figure 1 As shown, there are at least two conveyor lines, that is, more than two conveyor lines can be set, such as setting a first mounting rail 3, a second mounting rail 4, and a conveying mechanism on the first mounting rail 3 and the second mounting rail 4, further increasing the number of conveyor lines to further increase the conveying capacity of multi-line conveying. This application takes four conveyor lines as an example, and please refer to the attached drawings for details.

[0045] Further, refer to Figure 2 As shown, the first conveying member 11 includes a bearing portion 111 and a rolling portion 112. The first driving shaft 13 passes through the bearing portion 111 and is pivotally connected to the bearing portion 111. The rolling portion 112 is installed on the first driving shaft 13. The bearing portion 111 may include two sets of bearings. After the first driving shaft 13 passes through the two bearings, the two sets of bearings are respectively located on both sides of the rolling portion 112 to provide stable support for the rolling portion 112. The rolling portion 112 may adopt a metal roller. The metal roller can be wear-resistant and pressure-resistant. The steel billet rolling on the surface of the metal roller will not affect it, so that the rolling portion 112 can stably drive the steel billet to roll along the surface of the rolling portion 112 when following the rotation of the first driving shaft 13.

[0046] Specifically, the steel blank contacts the surface of the rolling portion 112. Driven by the first driving member 12 or the second driving member 22, the first driving shaft 13 pivots along the bearing portion 111, so that the rolling portion 112 is synchronously driven and rotated, thereby driving the steel blank to move along the surface of the rolling portion 112. When multiple sets of first conveying mechanisms 1 are set at the same time, multiple sets of first conveying members 11 are contained therein, so that the steel blank is supported at multiple points, ensuring that the steel blank is stably stressed and will not fall from the first conveying member 11 due to uneven stress.

[0047] Among them, reference Figure 2 As shown, the rolling portion 112 is provided with an annular inner groove 1121, and the steel blank is located in the inner groove 1121. The width of the inner groove 1121 is adapted to the width of the steel blank, so that when the steel blank moves, the moving trajectory will not deviate, and it will enter another inner groove 1121 from one inner groove 1121 and move accurately along the path of the inner groove 1121, thereby improving the accuracy of transportation.

[0048] In some embodiments, reference Figure 2 As shown, the second conveying member 21 has the same structure as the first conveying member 11, so that the steel billet of another conveying line can also move along the conveying path of the second conveying member 21, and the second conveying member 21 is staggered with the installation position of the first conveying member 11 during transportation. Therefore, when the steel billet needs to be lifted, picked up, rolled, etc. during the process, it will not affect the transportation of the steel billet of another conveying line.

[0049] For further reference, Figure 2 As shown, a heat conducting portion 231 is provided below the second drive shaft 23, and the heat conducting portion 231 covers the second drive shaft 23. The heat conducting portion 231 can adopt a heat conducting cover, which does not contact the second drive shaft 23 but covers the second drive shaft 23. A heat conducting platform can be provided at the bottom to connect with the ground or the first mounting rail 3 and the second mounting rail 4.

[0050] The main function of setting up the heat conducting part 231 is that, because the second drive shaft 23 needs to cross the conveying line of the first mounting rail 3 and then extend to the second mounting rail 4, and when the corresponding conveying line of the first mounting rail 3 conveys the steel billet, the excessively high temperature on the steel billet will be transmitted to the second drive shaft 23, and affect the second drive member 22 through the second drive shaft 23. Therefore, a heat conducting part 231 is set on the surface of the second drive shaft 23, which can shield the second drive shaft 23 and transfer heat to the second drive shaft 23. Most of the heat will be transferred to the heat conducting part 231, and then transferred to the ground or other mounting platforms through the heat conducting part 231, so as to avoid the second drive shaft 23 being affected by excessive heat.

[0051] In some embodiments, the conveying speeds of the first conveying mechanism 1 and the second conveying mechanism 2 are different, that is, the conveying speed of the first conveying mechanism 1 is faster than that of the second conveying mechanism 2 .

[0052] At the end of some conveying equipment, a lifting device will be used to lift the steel blank to a high processing point, and the lifting device will be set along the edge of the floor. Therefore, the conveyor line of the first mounting rail 3 on the periphery can generally be directly transported to the lifting device, while the conveyor line of the second mounting rail 4 on the inside can only use the lifting device to lift the steel blank on the second mounting rail 4 and place it on the conveyor line of the first mounting rail 3. Therefore, the speed is different. After the steel blank on the conveyor line of the first mounting rail 3 is lifted, the lifting device can be used to lift the steel blank on the conveyor line of the second mounting rail 4 to the first mounting rail 3, completing the intermittent switching of the steel blank for lifting to ensure improved conveying efficiency.

[0053] In some embodiments, reference Figure 1 or Figure 2 As shown, the first driving member 12 and the second driving member 22 are both provided with a heat insulation cover 5, and the first driving shaft 13 and the second driving shaft 23 both extend outward through the heat insulation cover 5. The heat insulation cover 5 is used to separate the first driving member 12 and the second driving member 22 toward the steel billet to prevent the heat emitted from the surface of the steel billet from affecting the first driving member 12 and the second driving member 22, so as to extend the service life of the first driving member 12 and the second driving member 22.

[0054] In some embodiments, the first driving member 12 may adopt a driving motor, and the second driving member 22 may include a driving bearing, a sprocket and a driving chain. The sprockets are divided into two groups, which are respectively installed on the first driving shaft 13 and the second driving shaft 23. The second driving shaft 23 is pivotally connected to the driving bearing, and the two sprockets are directly sleeved with a driving chain. The driving motor is used to drive the first driving shaft 13 to rotate, and the second driving shaft 23 can be driven to rotate along the driving bearing through the sprocket and the driving chain to complete the linkage drive, which is not shown in the figure.

[0055] This method can reduce the number of driving sources, lower power loss and reduce equipment consumables, but is suitable for steel billets with smaller weight and size. Steel billets with larger weight and size still require a separate driving source as in the above embodiment.

[0056] Furthermore, when this embodiment is adopted, a transmission 6 is also provided in the middle of the drive chain. Figure 3The transmission 6 structure shown in the figure includes a support bearing, a speed change shaft, a first speed change gear and a second speed change gear. The speed change shaft is pivotally connected to the support bearing, and the first speed change gear and the second speed change gear are both installed on the speed change shaft. The drive chain is divided into two, one is respectively connected to the sprocket on the first drive shaft 13 and the first speed change gear, and the other is respectively connected to the sprocket on the second drive shaft 23 and the second speed change gear. The diameters of the first speed change gear and the second speed change gear are different. For example, if the ratio of the first speed change gear to the second speed change gear is 1:2, the first speed change gear rotates one circle and the second speed change gear rotates half a circle, thereby achieving the effect of speed change. Through this structure, the different conveying speeds of the first conveying mechanism 1 and the second conveying mechanism 2 can be adapted.

[0057] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
