Description

Technical Field

[0001] This application relates to the field of grab bucket technology, specifically a leak-proof grab bucket for transporting metal particles. Background Technology

[0002] Grab buckets, as important lifting devices, are widely used in various loading and unloading operations. Currently, most grab buckets on the market used for transporting metal granules employ a fully mechanical mechanism. During lifting operations, this mechanism relies primarily on the cooperation of mechanical components to open and close the grab bucket and grasp the material. However, in actual use, these fully mechanical grab buckets exhibit significant sealing problems. When the grab bucket grasps metal granules for lifting, due to limitations in the precision of the mechanical structure and the influence of external forces such as vibration and bumps during lifting, it is difficult to achieve a tight seal at the joints between the grab buckets, resulting in leakage of metal granules through gaps.

[0003] Taking a port using traditional fully mechanical grab buckets to transport metal granules as an example, in a single operation of lifting 5 tons of metal granules, the amount of material leakage caused by poor sealing of the grab bucket is as high as 100-150 kg, with a material loss rate of 2%-3%. This not only wastes materials and increases transportation costs, but also pollutes the working environment. Cleaning up the leaked material also consumes a lot of manpower and time.

[0004] Therefore, it is necessary to provide a leak-proof metal particle transport grab to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a leak-proof transport grab for metal particles to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is: a metal particle leak-proof transport grab bucket, including a left bucket body and a right bucket body arranged symmetrically on the axis. A rotatable connecting unit is coaxially arranged on the top of the left bucket body and the right bucket body. A base is fixedly connected to both outer surfaces of the left bucket body and the right bucket body in the X direction. A connecting column is rotatably connected to the end of each base. An elastic element that can be elastically stretched is fixedly connected between the connecting column of the left bucket body and the connecting column of the right bucket body. The elastic element is arranged on both sides of the connecting column in the X direction.

[0007] Furthermore, the connecting column is L-shaped and has a mounting hole at its end. One end of the elastic element is fixedly connected to the mounting hole of the connecting column on the left bucket body, and the other end is fixedly connected to the mounting hole of the connecting column on the right bucket body.

[0008] Furthermore, the connecting unit includes a left connector, a right connector, and a fastener. The left connector is located on the top of the left bucket, and the right connector is located on the top of the right bucket. The left and right connectors are staggered and are rotatably connected by the fastener.

[0009] Furthermore, both the left and right buckets are welded with buckles in the Y direction. The buckles are located at the center of the outer side of the vertical profile of the left and right buckets, and the height of the base is lower than the buckles.

[0010] Furthermore, one end of the buckle has a protrusion that is away from the left and right buckets.

[0011] Furthermore, a hook is welded to the X-direction surface of the right bucket body, and the hook is located below the right connector.

[0012] Furthermore, a left rubber block and a right rubber block are fixedly connected to the top surfaces of the left and right buckets along the Y direction, respectively, and the left and right rubber blocks are aligned.

[0013] The beneficial effects of this application are: the metal particle leak-proof transport grab provided by this application, by setting up an elastic element, its elasticity will increase the pressure between the joint of the left and right buckets after the left bucket and the right bucket are closed, so that when the grab moves, the joint of the left and right buckets will remain in contact, preventing the metal particles from being lost.

[0014] By incorporating rubber blocks, the left and right buckets can be cushioned and worn when their tops are in contact, thus increasing the lifespan of the grab bucket. At the same time, the left and right buckets can be limited, allowing them to rotate up to a maximum angle of 180 degrees.

[0015] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1-2 As shown, this application provides a technical solution: a leak-proof transport grab for metal particles, comprising a left bucket body 1 and a right bucket body 2 arranged symmetrically on an axis. A rotatable connecting unit is coaxially arranged on the top of the left bucket body 1 and the right bucket body 2. A base 3 is fixedly connected to both outer surfaces of the left bucket body 1 and the right bucket body 2 in the X direction. A connecting post 31 is rotatably connected to the end of each base 3. An elastically retractable elastic element 9 is fixedly connected between the connecting post 31 of the left bucket body 1 and the connecting post 31 of the right bucket body 2. The elastic element 9 is provided on both sides of the connecting post 31 in the X direction. The elastic element 9 includes, but is not limited to, elastic ropes, springs, etc.

[0027] The connecting column 31 is L-shaped and has a mounting hole 311 at its end. One end of the elastic member 9 is fixedly connected to the mounting hole 311 of the connecting column 31 on the left bucket body 1, and the other end is fixedly connected to the mounting hole 311 of the connecting column 31 on the right bucket body 2.

[0028] The connecting unit includes a left connector 6, a right connector 7, and a fastener 8. The left connector 6 is located on the top of the left bucket 1, and the right connector 7 is located on the top of the right bucket 2. The left connector 6 and the right connector 7 are staggered and are rotatably connected by the fastener 8.

[0029] Fastener 8 includes a central shaft, bearings, hexagonal nuts, and washers. Bearings are concentrically arranged on both the left connector 6 and the right connector 7. The central shaft is set inside the two bearings, and the outer end of the central shaft is fixed by washers and hexagonal nuts.

[0030] Both the left bucket body 1 and the right bucket body 2 are welded with buckles 4 in the Y direction. The buckles 4 are located at the center of the outer side of the vertical profile of the left bucket body 1 and the right bucket body 2. The height of the base 3 is lower than that of the buckles 4.

[0031] The end of the buckle 4 has a protrusion 41, which is away from the left bucket 1 and the right bucket 2.

[0032] A hook 5 is welded to the X-direction surface of the right bucket body 2, and the hook 5 is below the right connecting piece 7.

[0033] Left rubber block 11 and right rubber block 21 are fixedly connected to the top surfaces of the left bucket 1 and right bucket 2 along the Y direction, respectively, and the left rubber block 11 and right rubber block 21 are aligned.

[0034] In one embodiment, the transport grab is used.

[0035] Specifically, secure the hoisting rope to buckle 4, and start the hoisting equipment to lift upwards, such as... Figure 3 As shown, at this time, the left bucket 1 and right bucket 2 are centered around the fastener 8, thus opening the bottom of the left bucket 1 and right bucket 2. Due to the weight of the left bucket 1 and right bucket 2 themselves, they overcome the elastic force of the elastic element 9, as shown. Figure 4 As shown, the top surfaces of the left bucket 1 and the right bucket 2 are brought close to each other. Due to the support of the left rubber block 11 and the right rubber block 21, the maximum angle between the left bucket 1 and the right bucket 2 is 180 degrees. The rubber blocks can reduce the impact when the tops of the two buckets are connected, thus enhancing the buffering effect.

[0036] The grab bucket is moved onto the metal pile using the hoisting equipment, so that the bottom openings of the left bucket 1 and right bucket 2 are pressed against the metal pile. The hoisting rope is removed from the clip 4 and connected to the hook 5. When the hoisting rope is lifted upward, the bottoms of the left bucket 1 and right bucket 2 close inward due to gravity. The elastic force of the elastic element 9 is overcome by the gravity of the left bucket 1 and right bucket 2. As the hook 5 gradually rises, the bottoms of the left bucket 1 and right bucket 2 gradually close. The bucket is filled with metal particles. After the left bucket 1 and right bucket 2 close, the hoisting equipment can move the grab bucket. At this time, the elastic element 9 still has elasticity. Its own elasticity strengthens the sealing effect at the connection between the left bucket 1 and right bucket 2, preventing gaps from forming at the connection between the left bucket 1 and right bucket 2 due to vibration or other factors when the grab bucket is lifted, thus preventing the loss of metal particles.

[0037] When the angle between the left bucket 1 and the right bucket 2 changes, the connecting column 31 rotates within the base 3, and the elastic force of the elastic element 9 increases or decreases with the distance between the two bases 3, always remaining horizontal.

[0038] In summary, this device, by incorporating an elastic element 9, increases the pressure at the joint between the left and right buckets 1 and 2 after they close, thus ensuring a tight seal at the joint during bucket movement and preventing metal particle leakage. The rubber block further reduces cushioning and wear when the tops of the left and right buckets 1 and 2 are in contact, increasing the lifespan of the grab bucket. It also limits the rotation of the left and right buckets 1 and 2, allowing a maximum rotation angle of 180 degrees. This solves the technical problem of metal particle leakage at the gaps caused by the difficulty in achieving a tight seal between the buckets during lifting, due to limitations in the mechanical structure's fit precision and the influence of external forces such as vibration and bumps during lifting.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
