[0031] Next, reference is made to Figures 1-4 Describe the feeding hopper 100 according to an embodiment of the present utility model.
[0032] As Figures 1-4 shown, the feeding hopper 100 according to an embodiment of the present utility model includes: a hopper body 10 and two lifting members 20, and the hopper body 10 is used for loading and unloading materials.
[0033] The hopper body 10 has a first direction (such as the left - right direction shown in Figure 1 ) and a second direction (such as the front - rear direction shown in Figure 1 ) that are perpendicular to each other. The two lifting members 20 are respectively arranged on the opposite sides of the hopper body 10 in the first direction (such as the left side and the right side shown in Figure 1 ). Each lifting member 20 has a lug shaft, and the hook of a crane can be hooked on the lug shaft, and the crane can drive the hook to move so as to drive the hopper body 10 to lift through the lifting member 20.
[0034] The two lifting members 20 are in the first direction (such as Figure 1correspond to each other in the left - right direction (as shown), so that the two lifting members 20 are in the same vertical plane extending in the first direction, which is conducive to ensuring that the center of gravity of the hopper body 10 is located on this plane, reducing the probability of the hopper body 10 tilting during lifting, improving the stability of the hopper body 10 during lifting, and enhancing the safety of operation.
[0035] Wherein, a lengthening member can be provided between each lifting member 20 and the hopper body 10. The lengthening member can extend in the first direction (such as Figure 1 the left - right direction as shown), which can extend the distance between the two lifting members 20, thereby extending the distance between the two hanger shafts. Compared with the technical solution of installing a special lifting tool on the hopper body 10, the hook of the crane can directly hook the two hanger shafts, which can simplify the operation process, shorten the time of direct feeding by the traveling crane, improve the operation rate of the traveling crane, and improve the operation rate of the converter, enhancing the production capacity of the converter.
[0036] According to the feeding hopper 100 of the present utility model embodiment, by providing a lengthening member between the lifting member 20 and the hopper body 10, the distance between the two lifting members 20 can be extended, thereby extending the distance between the two hanger shafts. Compared with the technical solution of installing a special lifting tool on the hopper body 10, the hook of the crane can directly hook the two hanger shafts, which can simplify the operation process and improve the operation rate of the converter, enhancing the production capacity of the converter.
[0037] such as Figure 1 shown, according to some embodiments of the present utility model, the hopper body 10 further has a third direction, and the third direction is perpendicular to the first direction (such as Figure 1 the left - right direction as shown) and the second direction (such as Figure 1 the front - back direction as shown). The lifting member 20 can extend in the third direction (such as Figure 1 the up - down direction as shown), and the hanger shaft can be provided at one end of the lifting member 20 (such as Figure 1 the upper end as shown), and the hanger shaft can be located above the hopper body 10 (such as Figure 1 above as shown), which can reduce the probability of interference between the hook of the crane and the hopper body 10, facilitating the hook of the crane to hook the hanger shaft and facilitating operation.
[0038] such as Figure 1 shown, in some examples, the feeding hopper 100 further includes: a lifting assembly 40, and the lifting assembly 40 can be provided on one side of the hopper body 10 in the second direction (such as Figure 1 the front - back direction as shown) (such as Figure 1The rear side shown), the lifting assembly 40 has a lifting ring, and the hook of the crane can be hooked to the lifting ring, and the crane can drive the hook to move, so as to drive the hopper body 10 to rotate around the axis of the lifting lug shaft through the lifting assembly 40, so that the material in the hopper body 10 can be discharged from the side of the hopper body 10 facing away from the lifting assembly 40 (such as Figure 1 The front side shown), so as to realize the discharging of the hopper body 10 and facilitate the operation.
[0039] Such as Figure 1 And Figure 2 As shown, in some examples, the lifting assembly 40 includes: a link fixing bracket 41, a lifting ring support 42 and a link. The link fixing bracket 41 and the lifting ring support 42 are positionally corresponding in the third direction (such as Figure 1 The up and down direction shown), so that the link fixing bracket 41 and the lifting ring support 42 are in the same vertical plane extending in the second direction, and it is beneficial to ensure that the center of gravity of the hopper body 10 is located on this plane, which can reduce the probability of the hopper body 10 tilting during the flipping process, and can improve the stability of the discharging of the hopper body 10 and enhance the safety of the operation.
[0040] Such as Figure 1 And Figure 2 As shown, in some examples, the lifting ring support 42 is located above the link fixing bracket 41 (such as Figure 1 The above shown), one end of the link (such as Figure 1 The lower end shown) is connected to the link fixing bracket 41, the other end of the link (such as Figure 1 The upper end shown) passes through the lifting ring support 42, and the lifting ring can be arranged at the other end of the link, so that the lifting ring is located above the lifting ring support �2, which can reduce the probability of interference between the hook of the crane and the hopper body 10, so as to facilitate the hook of the hook of the crane to the lifting ring and facilitate the operation.
[0041] Such as Figure 1 And Figure 2 As shown, in some examples, the lifting ring support 42 has a limiting hole 421, and the side of the limiting hole 421 facing away from the hopper body 10 (such as Figure 2 The rear side shown) is open to form a guiding opening 422, and the guiding opening 422 extends in the third direction (such as Figure 2 The up and down direction shown) to the two ends of the limiting hole 421 (such as Figure 2 The upper end and the lower end shown), so that a part of the link can enter the limiting hole 421 through the guiding opening 422, which can realize the limiting of the link and prevent the link from falling to the ground due to the link disengaging from the limiting hole 421.
[0042] At the same time, the top end of the limiting hole 421 (such as Figure 2The shape of the upper end shown can match the shape of the lifting ring, enabling the lifting ring to be limited in position, preventing the lifting ring from falling to the ground due to the chain link disengaging from the limiting hole 421, and improving the safety of the operation.
[0043] Among them, by providing a limiting hole 421 in the lifting ring support 42 and making the shape of the top end of the limiting hole 421 match the shape of the lifting ring, the probability of the chain link disengaging from the lifting ring support 42 when the hopper body 10 is not flipped can be reduced, thereby ensuring that the lifting ring is located above the lifting ring support 42, reducing the probability of interference between the crane hook and the hopper body 10, facilitating the crane hook to hook the lifting ring, and at the same time preventing the lifting ring from falling to the ground and improving the safety of the operation.
[0044] It can be understood that the chain link can disengage from the limiting hole 421 through the guiding port 422 when the hopper body 10 is flipped, ensuring that the chain link is in a vertically extended state when the hopper body 10 is flipped, improving the smoothness of the flipping of the hopper body 10, and increasing the maximum flipping angle of the hopper body 10, which is beneficial to the discharging of the hopper body 10.
[0045] As Figure 2 shown, in some examples, in the direction away from the chain link fixing frame 41 of the lifting ring support (such as Figure 2 the direction from bottom to top shown), the cross-section of the guiding port 422 gradually decreases in the third direction (such as Figure 2 the up-down direction shown), which can achieve the guiding of the chain link, improve the guiding effect on the chain link, improve the smoothness of a part of the chain link entering the limiting hole 421, and facilitate the operation.
[0046] At the same time, it can prevent the chain link from disengaging from the limiting hole 421 through the guiding port 422, reducing the probability of the chain link disengaging from the lifting ring support 42 when the hopper body 10 is not flipped, and improving the safety of the operation.
[0047] In some examples, the cross-sectional dimension of the lifting ring in the third direction (such as Figure 2 the up-down direction shown) is larger than the cross-sectional dimension of the limiting hole 421 in the third direction (such as Figure 2 the up-down direction shown), which can prevent the lifting ring from passing through the limiting hole 421 and falling to the ground, improving the reliability of the lifting ring limit, ensuring that the lifting ring is located above the lifting ring support 42, and reducing the probability of interference between the crane hook and the hopper body 10, facilitating the crane hook to hook the lifting ring.
[0048] As Figure 1 、 Figure 3 and Figure 4As shown, according to some embodiments of the present utility model, the lengthening member includes a plurality of support plates 31 and a plurality of reinforcing plates 32. The plurality of support plates 31 can be arranged on the charging hopper 100, which can extend the length of the lengthening member, thereby extending the distance between the two lifting members 20 and the distance between the two hanger shafts. The hook of the crane can directly hook the two hanger shafts, which can simplify the operation process, improve the operation rate of the converter, and increase the production capacity of the converter.
[0049] The plurality of support plates 31 can be sequentially connected to enclose a receiving cavity to ensure the structural strength of the lengthening member. The plurality of reinforcing plates 32 can be arranged on the charging hopper 100, and the plurality of reinforcing plates 32 can be located in the receiving cavity. Each reinforcing plate 32 is respectively connected to two opposite support plates 31, which can improve the structural strength of the lengthening member, reduce the probability of the lengthening member breaking due to load bearing, and is beneficial for the hopper body 10 to load more mass of materials.
[0050] It should be noted that, as Figure 4 shown, the number of the support plates 31 can be four. The four support plates 31 are sequentially connected to enclose a receiving cavity, and the four support plates 31 are grouped in pairs of two support plates 31. The two support plates 31 in each group of support plates 31 are arranged oppositely. The number of the reinforcing plates 32 can be two. The two reinforcing plates 32 are arranged in the receiving cavity. The two ends of each reinforcing plate 32 are respectively connected to the two support plates 31 in a group of support plates 31. On the basis of improving the structural strength of the lengthening member, space can be saved, and at the same time, the reinforcing plates 32 can be hidden, which is beneficial to improving the aesthetics of the lengthening member.
[0051] As Figure 1 and Figure 3 shown, according to some embodiments of the present utility model, the hopper body 10 includes: a bottom plate 13, a first side plate 11 and two second side plates 12. The first side plate 11 can be arranged on one side (such as the rear side shown in Figure 1 in the second direction (such as the front-rear direction shown in Figure 1 )) of the bottom plate 13. The two second side plates 12 can be respectively arranged on both sides (such as the front side and the rear side shown in Figure 1 in the first direction (such as the left-right direction shown in Figure 1 )) of the bottom plate 13. The two second side plates 12 are respectively connected to the first side plate 11. On the basis of ensuring the normal loading and unloading of materials of the hopper body 10, the materials can be blocked to prevent the materials in the hopper body 10 from leaking when the hopper body 10 is not overturned, and the operation safety can be improved.
[0052] As Figure 1 and Figure 4 shown, in some examples, in the direction (such as Figure 4In the direction from the rear to the front as shown, on the side of the second side plate 12 away from the first side plate 11 (such as Figure 4 the front side as shown), the edge extends obliquely towards the bottom plate 13 (such as Figure 4 the direction from top to bottom as shown), that is, in the direction from the rear to the front, the cross-sectional dimension of the front part of the second side plate 12 in the second direction gradually decreases, which is beneficial for a part of the hopper body 10 to extend into the furnace mouth of the boiler, can ensure that the materials in the hopper body 10 smoothly enter the boiler, thereby reducing the probability of the materials falling to the ground during the converter process, improving the operation rate of the converter, and enhancing the safety of operation.
[0053] Such as Figure 1 and Figure 3 shown, in some examples, the hopper body 10 further includes a plurality of ribs 131, the plurality of ribs 131 are respectively arranged on the bottom plate 13, and the plurality of ribs 131 can be arranged at intervals in the first direction (such as Figure 3 the left-right direction as shown), and each rib 131 can extend in the second direction (such as Figure 3 the front-rear direction as shown), which can increase the friction between the materials and the hopper body 10 to prevent the materials from sliding when the hopper body 10 is not overturned, reduce the probability of the materials falling to the ground during the converter process, thereby improving the operation rate of the converter, and enhancing the safety of operation.
