Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for steel smelting, and particularly relates to a scrap iron transfer bucket. Background Art
[0002] As a source of coolant and iron-containing materials, scrap steel plays an important role in both electric arc furnace and converter steelmaking. In electric arc furnace production, the usage amount of scrap steel can reach 100%, while in converter production, it usually contains 15%-25% of scrap steel. The use of scrap steel not only improves the energy efficiency of the steelmaking process but also helps to reduce greenhouse gas emissions, and it is an indispensable part of the steel production process.
[0003] The scrap iron transfer hopper is a container used to load and transport scrap steel, and it adds scrap steel into the converter or electric furnace during the steelmaking process. Generally, a flatbed truck is used to transport the scrap iron transfer hopper and scrap iron to the side of the converter or electric furnace. There are generally two groups of hanging ears, front and back, on the scrap iron transfer hopper. The hanging ears on the transfer hopper are connected to the hooks of the overhead crane, and the scrap iron transfer hopper is lifted. Then, the hanging ear in front of the transfer hopper is lifted to tilt the scrap iron transfer hopper and pour the scrap iron into the converter or electric furnace for smelting. There are hanging ears on both the left and right sides of the scrap iron transfer hopper. When the overhead crane hooks up the scrap iron transfer hopper, the operator needs to assist in connecting the hanging ear of the scrap iron transfer hopper to the hook of the overhead crane. During the connection process, relative position movement is likely to occur, resulting in the hook not being easily hooked to the hanging ear, and the manual auxiliary operation is time-consuming and laborious. In addition, during the flipping process of the existing scrap iron transfer bucket, the rotation between the scrap iron transfer bucket and the hook on the overhead crane is not smooth, and it is easy to get stuck, leading to the risk of the hook detaching during the hoisting process, seriously affecting the construction safety and the personal safety of the operator.
[0004] In summary, there is an urgent need for a scrap iron transfer bucket to solve or at least partially solve the problems existing in the prior art. Content of the Utility Model
[0005] The purpose of the utility model is to provide a scrap iron transfer bucket, aiming to solve the problem that during the connection process of the existing scrap iron transfer bucket, the relative position between the hook and the hanging ear is likely to move, resulting in the hook not being easily hooked to the hanging ear. The specific technical solution is as follows:
[0006] A scrap iron transfer bucket includes a transfer bucket body, two main hanging ears, and two secondary hanging ears. The two main hanging ears are respectively arranged on both sides of the front end of the transfer bucket body, and the two secondary hanging ears are respectively arranged on both sides of the rear end of the transfer bucket body. The main hanging ear includes a main fixing pin, a main limiting member, and a magnetic attracting member. The main fixing pin is fixedly connected to the transfer bucket body and is cantilevered outwards. The main limiting member is fixedly connected to the end of the main fixing pin far from the transfer bucket body. The magnetic attracting member is installed on the main limiting member, and there is a gap between the main limiting member and the transfer bucket body.
[0007] Further, it also includes a sleeve and a bearing ring. The bearing ring is sleeved and rotatably connected to the main fixing pin, the sleeve is sleeved and rotatably connected to the outside of the bearing ring, and the sleeve and the bearing ring are located within the gap.
[0008] Further, the main limiting member includes two integrally formed limiting arms. The two limiting arms are arranged crosswise, and reinforcing ribs are arranged on both of the two limiting arms. The reinforcing ribs are fixed to the limiting arms by welding.
[0009] Further, the secondary hanging ear includes a secondary fixing pin and a secondary limiting member. The secondary fixing pin is fixedly connected to the transfer hopper body and is arranged to protrude outward, and the secondary limiting member is fixedly connected to one end of the secondary fixing pin away from the transfer hopper body.
[0010] Further, the secondary limiting member is arranged in a strip shape.
[0011] Further, rounded corners are arranged at the bottom of the transfer hopper body, and there are two rounded corners, which are respectively arranged on both sides of the bottom of the transfer hopper body.
[0012] Further, U-shaped reinforcing plates are arranged on the outside of the transfer hopper body. The U-shaped reinforcing plates cover the transfer hopper body, and a plurality of U-shaped reinforcing plates are arranged along the length direction of the transfer hopper body.
[0013] Further, an extension frame is arranged below the transfer hopper body. The extension frame is arranged along the width direction of the transfer hopper body, and the extension frame extends toward both sides of the transfer hopper body.
[0014] Further, a chamfer is arranged above the transfer hopper body.
[0015] Further, both the U-shaped reinforcing plates and the extension frame are fixed to the transfer hopper body by welding.
[0016] Applying the technical solution of the present utility model has the following beneficial effects:
[0017] When the hook of the overhead crane is hooked to the main hanging ear, under the attraction of the magnetic component, it has a guiding effect on the hook, causing the hook of the overhead crane to move along the gap between the main limiting component and the transfer bucket body and be hooked to the main fixing pin, thus facilitating the hooking of the hook and the main hanging ear and making the operation convenient. By hooking the hook of the overhead crane to the main fixing pin and preventing the hook of the overhead crane from slipping under the blocking effect of the main limiting component. It should be noted that after the hook on the left side of the overhead crane is hooked to the main fixing pin, a magnetic attraction force is generated on the hook of the overhead crane by the magnetic component, causing the hook of the overhead crane to be pressed against the limiting arm under the action of the magnetic attraction force, thus generating a static friction force between the hook of the overhead crane and the limiting arm, so as to prevent the hook on the left side of the overhead crane from falling off when hooking the hook on the right side of the overhead crane. On the one hand, it reduces the trouble of rehooking after the hook falls off, and on the other hand, it prevents the problem that the transfer bucket body overturns during hoisting due to the failure to detect in time after the hook falls off.
[0018] In addition, through the setting of the sleeve, the sleeve can rotate with the main fixing pin, so that during the hoisting process, the sleeve rotates with the lifting hook, preventing the hook from getting stuck with the main fixing pin. In addition, through the setting of the bearing ring, the friction between the sleeve and the main fixing pin can be reduced, thus improving the service life of the sleeve and the main fixing pin. In addition, through the arrangement of the bearing ring, the friction force between the sleeve and the main fixing pin is smaller and the rotation is smoother.

[0026] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below, and preferred embodiments of the present utility model are given. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present utility model more thorough and comprehensive.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
[0028] Embodiment:
[0029] See Figures 1-4 , this embodiment provides a scrap iron transfer bucket, including a transfer bucket body 1, two main hanging ears 2 and two sub-hanging ears 3. The two main hanging ears 2 are respectively arranged on both sides of the front end of the transfer bucket body 1, and the two sub-hanging ears 3 are respectively arranged on both sides of the rear end of the transfer bucket body 1. The main hanging ear 2 includes a main fixing pin 21, a main limiting part 22 and a magnetic part 23. The main fixing pin 21 is fixedly connected to the transfer bucket body 1 and is arranged to project outwards. The main limiting part 22 is fixedly connected to the end of the main fixing pin 21 away from the transfer bucket body 1, and the magnetic part 23 is installed on the main limiting part 22. There is a gap between the main limiting part 22 and the transfer bucket body 1.
[0030] Specifically, the upper and rear sides of the transfer bucket body 1 are open to facilitate the feeding of scrap iron materials from above and pouring out from the rear. The two main hanging ears 2 are respectively arranged on both sides of the front end of the transfer bucket body 1, and the two sub-hanging ears 3 are respectively arranged on both sides of the rear end of the transfer bucket body 1. The two main hanging ears 2 and the two sub-hanging ears 3 are simultaneously hooked and lifted by four hooks on the overhead crane, so as to conveniently move the transfer bucket body 1 on the transport vehicle to near the converter or electric furnace, and pour the scrap iron in the transfer bucket body 1 into the converter or the electric furnace.
[0031] Understandably, when the hook of the overhead crane is hooked to the main hanging ear 2, under the attraction of the magnetic component 23, it has a guiding effect on the hook, causing the hook of the overhead crane to move along the gap between the main limiting component 22 and the transfer bucket body 1 and be hooked to the main fixing pin 21, thus facilitating the hooking of the hook and the main hanging ear 2. By hooking the hook of the overhead crane to the main fixing pin 21 and preventing the hook of the overhead crane from slipping under the blocking effect of the main limiting component 22. It should be noted that after the hook on the left side of the overhead crane is hooked to the main fixing pin 21, the magnetic component 23 generates a magnetic attraction force on the hook of the overhead crane, causing the hook of the overhead crane to be pressed against the limiting arm 221 under the action of the magnetic attraction force. Therefore, a static friction force is generated between the hook of the overhead crane and the limiting arm 221, thereby preventing the hook on the left side of the overhead crane from falling off when the hook on the right side of the overhead crane is hooked. On the one hand, it reduces the trouble of rehooking after the hook falls off. On the other hand, it prevents the transfer bucket body 1 from tipping over during hoisting due to the hook falling off and not being discovered in time. In this embodiment, the magnetic component 23 is a magnet.
[0032] Furthermore, it further includes a sleeve 24 and a bearing ring 25. The bearing ring 25 is sleeved and rotatably connected to the main fixing pin 21, and the sleeve 24 is sleeved and rotatably connected to the outside of the bearing ring 25. The sleeve 24 and the bearing ring 25 are in the gap.
[0033] Understandably, during the flipping process of the existing scrap iron transfer bucket, the rotation between the scrap iron transfer bucket and the hook on the overhead crane is not smooth, and it is easy to get stuck, resulting in the risk of the hook detaching during the hoisting process, seriously affecting construction safety and the personal safety of operators. Through the setting of the sleeve 24, the sleeve 24 can rotate with the main fixing pin 21, so that during the hoisting process, the sleeve 24 rotates with the hook together, preventing the hook from getting stuck with the main fixing pin 21. In addition, through the setting of the bearing ring 25, the friction between the sleeve 24 and the main fixing pin 21 can be reduced, thereby improving the service life of the sleeve 24 and the main fixing pin 21. In addition, through the arrangement of the bearing ring 25, the friction force between the sleeve 24 and the main fixing pin 21 is smaller and the rotation is smoother.
[0034] Furthermore, the main limiting component 22 includes two integrally formed limiting arms 221. The two limiting arms 221 are arranged crosswise, and reinforcing ribs 222 are arranged on both of the two limiting arms 221. The reinforcing ribs 222 are fixed to the limiting arms 221 by welding.
[0035] Specifically, the magnetic component 23 is detachably installed on the two limiting arms 221.
[0036] Understandably, after the overhead crane hooks onto the main hanging ear 2, the main blocking member blocks the hook of the overhead crane, preventing the hook of the overhead crane from falling off the main hanging ear 2 and causing the transfer bucket body 1 to tilt uncontrollably. This further ensures the safety of the transfer bucket body 1 during the hoisting process.
[0037] Further, the secondary hanging ear 3 includes a secondary fixing pin 31 and a secondary limiting member 32. The secondary fixing pin 31 is fixedly connected to the transfer bucket body 1 and is arranged to project outwards, and the secondary limiting member 32 is fixedly connected to the end of the secondary fixing pin 31 away from the transfer bucket body 1.
[0038] Understandably, through the arrangement of the secondary hanging ear 3, the overhead crane lifts the main hanging ear 2, causing the transfer bucket body 1 to rotate around the secondary hanging ear 3, tilting the transfer bucket body 1, and thus pouring out the scrap iron in the transfer bucket body 1.
[0039] Further, the secondary limiting member 32 is arranged in a strip shape.
[0040] Specifically, a vertically arranged long hole is arranged on the hook of the overhead crane. When the hook is hooked onto the secondary hanging ear 3, the hook is put over the secondary limiting member 32 and the hook is hooked onto the secondary fixing pin 31. When putting the hook over the secondary limiting member 32, the hook needs to be rotated horizontally so that the long hole on the hook corresponds to the long strip of the secondary limiting member 32. When the hook moves to the secondary fixing pin 31, the long hole on the hook intersects with the long strip of the secondary limiting member 32, thus preventing the hook from falling off the secondary hanging ear 3.
[0041] Further, two rounded corners 11 are arranged at the bottom of the transfer bucket body 1, and the two rounded corners 11 are respectively arranged on both sides of the bottom of the transfer bucket body 1.
[0042] Understandably, through the arrangement of the rounded corners 11, the scrap iron in the transfer bucket body 1 can be poured out more conveniently, preventing the scrap iron from getting stuck at the corners. In addition, the arrangement of the rounded corners 11 makes the shape of the rear discharge port of the transfer bucket body 1 become round, making it convenient to dock with a converter or an electric furnace and facilitating the pouring of the scrap iron in the transfer bucket into the converter or the electric furnace.
[0043] Further, a U-shaped reinforcing plate 4 is arranged on the outside of the transfer bucket body 1. The U-shaped reinforcing plate 4 is arranged to cover the transfer bucket body 1, and a plurality of U-shaped reinforcing plates 4 are arranged along the length direction of the transfer bucket body 1.
[0044] Understandably, the rigidity of the transfer bucket body 1 is strengthened by the U-shaped reinforcing plate 4, improving the anti-deformation ability of the transfer bucket. When the scrap iron is put into the transfer bucket, an impact will be generated, and the impact resistance ability of the transfer bucket body 1 strengthened by the U-shaped reinforcing plate 4 is enhanced, improving the anti-deformation ability of the transfer bucket body 1.
[0045] Furthermore, an extension frame 5 is arranged below the transfer hopper body 1. The extension frame 5 is arranged along the width direction of the transfer hopper body 1 and extends towards both sides of the transfer hopper body 1.
[0046] Specifically, the bottom of the extension frame 5 is supported on the transfer hopper body 1. A plurality of extension frames 5 are arranged along the length direction of the transfer hopper body 1. By means of the extension frames 5, the supporting area is increased, thereby reducing the pressure of the transfer hopper body 1 on the transport vehicle and preventing local damage to the hopper of the transport vehicle. On the other hand, increasing the supporting area can improve the stability of the transfer hopper body 1 placed on the transport vehicle.
[0047] Furthermore, a chamfer 12 is arranged above the transfer hopper body 1.
[0048] It can be understood that when the scrap iron in the transfer hopper needs to be dumped into the converter or the electric furnace, the furnace mouth of the converter is relatively small. After the upper part of the transfer hopper body 1 passes through the chamfer 12, it can adapt to the size of the furnace mouth of the converter or the electric furnace, enabling the transfer hopper body 1 to partially extend into the furnace mouth of the converter or the electric furnace and preventing the scrap iron from falling out of the transfer hopper body 1 when adding the scrap iron into the converter or the electric furnace.
[0049] Furthermore, both the U-shaped reinforcing plate 4 and the extension frame 5 are fixed to the transfer hopper body 1 by welding.
[0050] It can be understood that fixing by welding makes the U-shaped reinforcing plate 4 and the extension frame 5 more reliably fixed to the transfer hopper body 1, making the overall strength of the transfer hopper body 1, the U-shaped reinforcing plate 4 and the extension frame 5 higher.
[0051] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
