An alloy storage and transportation container for steelmaking

Abstract

This invention proposes an alloy storage and transportation container for steelmaking, comprising a box body, an openable and closable lid on the top surface of the box body, and an openable and closable unloading base plate on the bottom surface of the box body. A locking pin is provided on the side of the base plate. A rotating arm is rotatably mounted on the side of the box body via a first pin, and one end of the rotating arm is provided with a locking hook that engages with the locking pin. The rotating arm is configured such that when the rotating arm is rotated in the forward direction, it causes the locking hook to rotate and disengage from the locking pin, allowing the base plate to rotate and open around the hinge under its own weight. When the base plate is closed and the rotating arm is rotated in the reverse direction, it causes the locking hook to rotate and lock with the locking pin. This invention achieves a labor-saving and rapid bottom unloading structure by using the rotating arm to engage the locking hook with the locking pin on the side of the base plate, effectively replacing the traditional manual pin-type unloading method, significantly reducing operational intensity and improving unloading efficiency. Simultaneously, the design of the base plate automatically opening under gravity ensures thorough unloading and low residue.

Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and in particular to an alloy storage and transportation container for steelmaking. Background Technology

[0002] In steel smelting and production, various alloys (such as ferromanganese, ferrosilicon, and metallic chromium) are generally stored and transported in block or granular form. Existing alloy storage containers are mostly open pallets or flat boxes, which have the following drawbacks:

[0003] Inefficient unloading and high residue: Most containers rely on "top unloading (residual materials need to be manually removed)" or "overall tilting unloading (requires additional equipment and is cumbersome to operate)", which cannot meet the "fast and low residue" unloading requirements of steelmaking stations;

[0004] Poor compatibility of unloading structure: Traditional bottom unloading devices are mostly "manual pin direct opening type", which is laborious to operate and occupies bottom space;

[0005] Therefore, there is an urgent need for a storage and transportation container specifically designed for steelmaking alloys to solve industry pain points such as "difficult unloading and high residue" in order to improve the unloading efficiency of alloys and reduce the intensity of manual labor. Utility Model Content

[0006] This utility model proposes an alloy storage and transportation container for steelmaking, which solves the problems of difficult unloading and high residue in existing alloy storage and transportation containers.

[0007] The technical solution of this utility model is implemented as follows:

[0008] This utility model provides an alloy storage and transportation container for steelmaking, including a box body. The top surface of the box body is provided with an openable and closable box cover, and the bottom surface of the box body is provided with an openable and closable unloading base plate. The side of the base plate is provided with a locking pin. A rotating arm is rotatably mounted on the side of the box body via a first pin shaft. One end of the rotating arm is provided with a locking hook that cooperates with the locking pin. The rotating arm is configured such that: when the rotating arm is rotated in the forward direction, the rotating arm drives the locking hook to rotate and disengage from the locking pin, and the base plate rotates around the hinge under its own gravity to open; when the base plate is closed and the rotating arm is rotated in the reverse direction, the rotating arm drives the locking hook to rotate and lock with the locking pin.

[0009] Specifically, the side of the box is also provided with a rocker arm. The rocker arm is rotatably mounted on the side of the box via a second pin. A sliding groove is provided on the short arm of the rocker arm. A sliding pin is slidably installed in the sliding groove. The sliding pin is fixedly connected to the end of the rotating arm away from the locking hook. By pulling the long arm end of the rocker arm to rotate around the second pin, the rotating arm is driven to rotate around the first pin.

[0010] Furthermore, a return spring is connected between the long arm end of the rocker arm and the side of the housing. The return spring is used to provide tension to force the rocker arm to rotate in the positive direction, thereby causing the rotating arm to rotate in the opposite direction to reset the lock hook.

[0011] Specifically, the base plate is a double-opening door panel, and both base plates are provided with locking pins on their sides. The end of the rotating arm is provided with two locking hooks that respectively cooperate with the locking pins on the two base plates.

[0012] Furthermore, each of the base plates is provided with a support base at its bottom.

[0013] Furthermore, guide wheels are rotatably mounted on the bottom of the opposite side of the support base.

[0014] Furthermore, the bottom side of the support base has a slot for the forks of a forklift to pass through.

[0015] Specifically, the top of the box is equipped with a lifting ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) This utility model achieves a bottom unloading structure that is labor-saving and quick to open and close by using a rotating arm to drive the locking hook to cooperate with the locking pin on the side of the bottom plate. This mechanism effectively replaces the traditional manual pin-type unloading method, significantly reduces the operating intensity, and improves the unloading efficiency; at the same time, the design of the bottom plate automatically opening under the action of gravity ensures thorough unloading and low residue, perfectly meeting the process requirements of steelmaking site for fast and clean unloading;

[0018] (2) This utility model, by setting a rocker arm on the side of the container and utilizing the lever ratio between its long and short arm ends, allows the operator to apply only a small force to the long arm end, which can drive the rotating arm through the sliding groove and sliding pin mechanism to complete the unloading action of a large load. This design greatly reduces the operating intensity and realizes labor-saving operation; at the same time, arranging the main operating components on the side of the container avoids interference with the bottom handling structure, optimizes the spatial layout, and makes the unloading operation safer and more convenient, especially suitable for steelmaking operation scenarios that require frequent opening and closing;

[0019] (3) This utility model sets a reset spring to automatically reset the rocker arm and rotating arm when not in operation, ensuring that the locking hook is always in a locked state, which enhances the safety and sealing during storage and transportation.

[0020] (4) By adopting a double-opening unloading gate panel and symmetrically arranged locking hooks and locking pins, this utility model achieves rapid and uniform unloading, further reduces material residue, and improves the thoroughness of unloading;

[0021] (5) By setting a support base under each bottom plate, this utility model enhances the stability and load-bearing capacity of the overall structure and extends the service life of the container; by setting guide wheels at the bottom of the support base, the bottom plate is forced to rotate and close when the container is lowered by the weight of the container itself; the guide wheels effectively reduce the frictional resistance between the support base and the ground, which not only makes the bottom plate closing process smoother and avoids jamming, but also significantly reduces the wear on the support base and the ground, protects the integrity of the equipment structure, extends the service life, and ensures that the unloading door can be reliably sealed.

[0022] (6) By reserving forklift fork slots on the side of the support base, this utility model achieves seamless connection with the forklift handling system, meeting the needs of short-distance and efficient transfer operations in the workshop; at the same time, by setting lifting rings on the top of the box, it is convenient for overhead cranes or cranes to carry out lifting operations, meeting the needs of long-distance and high-height handling, and enhancing the multi-scenario applicability of the container.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Reference Figures 1 to 3 This utility model provides an alloy storage and transportation container for steelmaking, including a box body 1. The top surface of the box body 1 is provided with an openable and closable box cover 2, and the bottom surface of the box body 1 is provided with an openable and closable unloading base plate 3. The side of the base plate 3 is provided with a locking pin 4. A rotating arm 6 is rotatably mounted on the side of the box body 1 via a first pin 5. One end of the rotating arm 6 is provided with a locking hook 7 that cooperates with the locking pin 4. The rotating arm 6 is configured such that when the rotating arm 6 is rotated in the forward direction, the rotating arm 6 drives the locking hook 7 to rotate and disengage from the locking pin 4, and the base plate 3 rotates and opens around the hinge under its own weight. When the base plate 3 is closed and the rotating arm 6 is rotated in the reverse direction, the rotating arm 6 drives the locking hook 7 to rotate and lock with the locking pin 4.

[0031] This invention utilizes a rotating arm 6 to engage a locking hook 7 with a locking pin 4 on the side of the base plate 3, achieving a bottom unloading structure that is labor-saving and quick to open and close. This mechanism effectively replaces the traditional manual pin-type unloading method, significantly reducing operational intensity and improving unloading efficiency. Simultaneously, the automatic opening design of the base plate 3 under gravity ensures thorough unloading with minimal residue, perfectly meeting the process requirements of rapid and clean unloading in steelmaking operations.

[0032] In this embodiment, the main body of the box 1 is a frame structure made of carbon steel or stainless steel, roughly rectangular in shape, with dimensions of approximately 1238mm (length) × 800mm (width) × 850mm (height). The frame of the box 1 is a closed three-dimensional grid support structure formed by fully welded vertical and horizontal bars supplemented with reinforcing ribs to ensure sufficient strength to bear the heavy load of the alloy. The box 1 is covered with sealed side panels, forming a closed cavity with an open top and bottom. A hinged lid 2 (not shown in the figure) is installed at the top opening of the box 1. A sealing strip can be provided at the contact edge between the lid 2 and the box 1 for moisture prevention, dust prevention, and oxidation prevention.

[0033] like Figures 1 to 3As shown, in order to achieve labor-saving operation, a rocker arm 8 is also provided on the side of the box 1. The rocker arm 8 is rotatably mounted on the side of the box 1 via a second pin 9. A groove 10 is provided on the short arm of the rocker arm 8. A sliding pin 11 is slidably installed in the groove 10 (the cooperation between the groove 10 and the sliding pin 11 can avoid mechanical interference between the movement of the end of the rocker arm 8 and the movement of the end of the rotating arm 6). The sliding pin 11 is fixedly connected to the end of the rotating arm 6 away from the locking hook 7. By pulling the long arm end of the rocker arm 8 to rotate around the second pin 9, the rotating arm 6 is driven to rotate around the first pin 5. By setting the rocker arm 8 on the side of the box 1 and utilizing the lever ratio between its long arm end and short arm end, the operator only needs to apply a small force to the long arm end to drive the rotating arm 6 to complete the release action of a large load through the mechanism of the groove 10 and the sliding pin 11. This design greatly reduces the intensity of operation and achieves labor-saving operation. At the same time, the main operating components are arranged on the side of the container, avoiding interference with the bottom handling structure, optimizing the spatial layout, and making the unloading operation safer and more convenient. It is especially suitable for steelmaking operations that require frequent opening and closing.

[0034] Furthermore, such as Figure 1 , 2 As shown, a return spring 12 is connected between the long arm end of the rocker arm 8 and the side of the box 1. The return spring 12 is used to provide a pulling force to force the rocker arm 8 to rotate in the positive direction, and drive the rotating arm 6 to rotate in the opposite direction to reset the locking hook 7. By setting the return spring 12, the rocker arm 8 and the rotating arm 6 are automatically reset in the non-operational state, ensuring that the locking hook 7 is always in the locked state, which enhances the safety and sealing during storage and transportation.

[0035] In this embodiment, as Figure 3 As shown, both sides of the housing 1 are equipped with components such as rocker arms 8, return springs 12, rotating arms 6, locking hooks 7, and locking pins 4. The long arms of the two rocker arms 8 are connected by a crossbar (not shown in the figure). During operation, pulling the crossbar directly can drive the two rocker arms 8 to rotate simultaneously, thereby driving the rotating arms 6 on both sides of the housing 1 to rotate, so that the two sets of locking hooks 7 on both sides of the housing 1 can release the corresponding locking pins 4 at the same time. The above-mentioned locking and unlocking components are set on both sides of the housing 1, which makes the force more balanced and the service life longer.

[0036] Specifically, such as Figure 1 , 2 As shown, the base plate 3 is a double-opening door panel, and the sides of both base plates 3 are provided with locking pins 4. The end of the rotating arm 6 is provided with two locking hooks 7 that respectively cooperate with the locking pins 4 on the two base plates 3. By adopting a double-opening unloading door panel, and with the symmetrically arranged locking hooks 7 and locking pins 4, fast and uniform unloading is achieved, further reducing material residue and improving the thoroughness of unloading.

[0037] In this embodiment, as Figure 1As shown, the first pin 5 is located directly above the two locking hooks 7. This design allows the weight of the base plate 3 and the alloy material to act on the locking hooks 7 through the locking pin 4, making the locking hooks 7 and locking pin 4 more secure. The locking hooks 7 and locking pin 4 are not easily disengaged by shaking when locked.

[0038] Furthermore, such as Figures 1 to 3 As shown, each of the base plates 3 is provided with a support seat 13 at its bottom. By providing a support seat 13 under each base plate 3, the stability and load-bearing capacity of the overall structure are enhanced, and the service life of the container is extended.

[0039] Furthermore, such as Figure 1 , 2 As shown, guide wheels 14 are rotatably mounted on the bottom of the opposite side of the support base 13. By setting guide wheels 14 at the bottom of the support base 13, the bottom plate 3 is forced to rotate and close when the container is lowered by the weight of the box body 1. The guide wheels 14 effectively reduce the frictional resistance between the support base 13 and the ground, which not only makes the closing process of the bottom plate 3 smoother and avoids jamming, but also significantly reduces the wear on the support base 13 and the ground, protects the structural integrity of the equipment, extends its service life, and ensures that the unloading door can be reliably sealed.

[0040] Furthermore, such as Figure 3 As shown, the bottom side of the support base 13 has a slot 15 for the forklift forks to pass through (usually arranged symmetrically front and back, located on the adjacent side of the locking hook 7). The slot 15 is designed to be about 250mm wide and about 60mm high to accommodate standard forklift forks. By reserving the forklift fork slot 15 on the side of the support base 13, seamless docking with the forklift handling system is achieved, meeting the needs of short-distance and efficient transfer operations within the workshop.

[0041] Specifically, such as Figures 1 to 3 As shown, the top of the container 1 is provided with a lifting ring 16. By setting the lifting ring 16 on the top of the container 1, it is convenient for overhead cranes or cranes to carry out lifting operations, meet the needs of long-distance and high-altitude handling, and enhance the multi-scenario applicability of the container.

[0042] The working process of this utility model's alloy storage and transportation container mainly includes two stages: storage and transfer, and unloading.

[0043] (1) Storage and transfer process:

[0044] Loading: Open the top cover 2, load the block or granular alloy (such as ferromanganese, ferrosilicon, etc.) into the box 1, and then close the cover 2 to ensure a seal.

[0045] Short-distance transport: The forklift can lift the entire box 1 by inserting its forks into the slots 15 at the bottom of the support base 13 and transport it to the designated location in the steelmaking workshop.

[0046] Lifting and transport: When long-distance transport or transport across obstacles is required, use an overhead crane or hoist to lift the container 1 through the lifting ring 16 on the top of the container 1 for transport.

[0047] (2) Unloading process:

[0048] Positioning: Transport container 1 to the unloading point (e.g., above the hopper in front of the steelmaking furnace) using a forklift or overhead crane and place it stably. At this time, the gravity of the alloy material inside container 1 acts on the bottom plate 3 and is transmitted to the connection between the locking pin 4 and the locking hook 7, ensuring the stability of the connection between the locking hook 7 and the locking pin 4. The bottom plate 3 is in a reliably closed state, such as... Figure 1 As shown.

[0049] Initiating unloading: The operator stands to the side of the container and pulls down the long end of the rocker arm 8. Through leverage, a small operating force is transmitted and amplified via the rocker arm 8, slide groove 10, and sliding pin 11 mechanism, driving the rotating arm 6 to rotate. This causes the locking hook 7 at the end of the rotating arm 6 to rotate and disengage from the locking pin 4 on the base plate 3. After the locking is released, the two unloading base plates 3 quickly rotate downwards around the hinge under the weight of the material itself, opening as if... Figure 2 As shown, the alloy material is discharged evenly and quickly from the double opening at the bottom, leaving very little residue; at this time, the rocker arm 8, relying on the automatic reset function of the reset spring 12, drives the rotating arm 6 to reverse, causing the locking hook 7 to rotate to the initial position.

[0050] Closing and Resetting: After unloading, use the overhead crane to slightly lift the container, allowing the unloading base plate 3 to naturally droop under gravity. Then, slowly lower the container, with the guide rollers 14 at the bottom of the support base 13 contacting the ground first. As the container 1 continues to lower, the guide rollers 14 roll, and the weight of the container 1 presses against the base plate 3, causing it to rotate upwards around the hinge and close. When the locking pin 4 abuts against the outer bottom surface of the locking hook 7, as the container 1 continues to lower, the locking hook 7, under the action of the locking pin 4, will drive the rotating arm 6 to rotate forward (the bottom of the locking hook 7 is arc-shaped, which can guide the relative movement of the locking pin 4 and the locking hook 7), until the locking pin 4 engages with the locking hook 7 to achieve locking. Figure 1 As shown, the base plate 3 is closed and locked.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
