Description

Technical Field

[0001] This invention belongs to the field of steelmaking machinery technology, and specifically relates to a horizontal push-pull and front-and-back flipping type converter slag-blocking mechanism transportation and storage device for online replacement, transportation and storage of converter slag-blocking mechanism installed at the converter tapping port. Background Technology

[0002] The converter slag-blocking tapping process involves molten steel flowing through the tapping hole brick, the slag-blocking mechanism's sliding plate brick, and the outer nozzle brick before being injected into the ladle. When infrared slag detection is activated, the hydraulic cylinder is driven to quickly close the sliding plate brick, completing the entire tapping hole slag-blocking operation.

[0003] To ensure the safety of the converter slag-blocking mechanism, the tapping brick, sliding plate brick, and outer nozzle brick must be replaced after a certain number of uses. Currently, the common practice is to replace the entire converter slag-blocking mechanism online. This means that the used slag-blocking mechanism is removed and immediately transported away and replaced with a new one, in order to minimize the replacement time and reduce the impact on steelmaking production.

[0004] When replacing a horizontally installed slag-blocking mechanism online, the hot, intact machine, freshly removed from the tapping flange, is lifted using a crane and placed smoothly and quickly on a transport and storage device for transport. The replacement of the new slag-blocking mechanism is then completed smoothly and quickly by lifting it from the transport and storage device. This is a crucial step in the online replacement of slag-blocking mechanisms. Therefore, designing a simple, reliable, easy-to-operate, and safe transport and storage device for slag-blocking mechanisms is essential for shortening online replacement time, reducing worker labor intensity, improving the quality of slag-blocking mechanism replacement, and ensuring the continuity of steelmaking production. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a horizontal push-pull and front-and-back tilting converter slag-blocking mechanism transportation and storage device.

[0006] The technical solution of this invention is: a horizontal push-pull and front-and-back tilting converter slag-blocking mechanism transportation and storage device, comprising a base assembly, a storage panel assembly, supporting side plates, and a storage locking assembly. The storage panel assembly mainly consists of a storage panel and positioning columns arranged side-by-side at the bottom of the storage panel. The storage panel is inclined above the base assembly. Supporting side plates are provided between the two sides of the storage panel and the two ends of the base assembly, connecting the storage panel and the base assembly together. The storage locking mechanism assembly mainly consists of a horizontal plate and two locking components, and is equipped with... The horizontal plate is placed on top of the storage panel and connected to the storage panel and two supporting side plates. Two locking components are arranged at both ends of the horizontal plate. The locking components mainly consist of hook iron, inner vertical plate, outer vertical plate, push-pull sleeve, rotating pin, and push-pull handle. The inner vertical plate and outer vertical plate are fixed between the horizontal plate and the storage panel. The rotating pin passes through the outer vertical plate, hook iron, and inner vertical plate in sequence, rotatably connecting the hook iron between the inner vertical plate and the outer vertical plate. The push-pull sleeve is fixed to the outer vertical plate with screws. The push-pull handle is slidably fitted inside the push-pull sleeve.

[0007] Preferably, the base assembly is a rectangular frame composed of rectangular steel tubes and channel steel, and the rectangular steel tubes are provided with rectangular fork holes inside.

[0008] Preferably, the supporting side plate is a steel plate and is trapezoidal in shape.

[0009] Preferably, the storage panel is provided with a fully enclosed waist-shaped hole or a semi-open U-shaped hole above it, and the waist-shaped hole or U-shaped hole is symmetrically arranged and located above the positioning post.

[0010] Preferably, both ends of the hook are L-shaped, the inner side of the front hook body is the hook locking surface, the outer side of the rear hook body is the push-pull locking surface, a flipping stop surface is provided at the corner above the push-pull locking surface, and a rotating hole C is provided at the lower end of the rear hook body.

[0011] Preferably, the push-pull sleeve mainly consists of a connecting flange and a sleeve, with a through push-pull hole C in the middle, threaded holes around the connecting flange, and an L-shaped push-pull groove on the upper side wall of the sleeve. The push-pull handle consists of a push-pull rod and a handle connected as one piece. When the handle is at the end of the push-pull groove, the push-pull rod retracts to the outer vertical plate, and the hook iron rotates freely along the rotating pin. When the handle is at the beginning of the push-pull groove, the push-pull rod extends to the inner vertical plate and blocks behind the push-pull locking surface, locking the hook iron.

[0012] Preferably, the inner upright plate is provided with a rotating hole A and a push-pull hole A, and the outer upright plate is provided with a rotating hole B, a push-pull hole B, and a fixing bolt hole. The fixing bolt hole and the threaded hole of the push-pull sleeve are arranged concentrically. The rotating holes A, B, and C are the same size and correspond in position. The rotating pin is T-shaped and passes through the outer upright plate, the hook iron, and the inner upright plate in sequence, so that the hook iron flips back and forth along the rotating pin. The push-pull holes A, B, and C are the same size and correspond in position, so that the push-pull handle slides between the push-pull holes.

[0013] Preferably, the outer vertical plate and the push-pull sleeve of the two locking components are completely symmetrical, and the hook, inner vertical plate, rotating pin and push-pull handle are completely identical.

[0014] Preferably, the included angle E between the storage panel and the rectangular steel pipe is 90° to 120°.

[0015] 1. The locking assembly is equipped with a push-pull sleeve, a push-pull handle, a hook, and a horizontal plate. When the push-pull handle is pulled back to the end of the push-pull groove, the push-pull rod is fully retracted. The hook is flipped backward until the flipping stop surface touches the support surface of the horizontal plate, at which point it automatically stops rotating. The rotation angle of the hook is controlled within 160°. When the hook needs to lock the slag-blocking mechanism, push the hook forward with a little force so that it presses down and hooks the slag-blocking mechanism under gravity. At the same time, push the handle forward to the beginning of the push-pull groove so that the push-pull rod is fully extended and the hook is locked. Throughout the process, the push-pull handle is always inside the push-pull sleeve and slides horizontally, which greatly facilitates on-site operation, improves work efficiency, and reduces the labor intensity of workers.

[0016] 2. The locking assembly is positioned directly behind the fixed claw of the slag-blocking mechanism. It rotates using a back-and-forth flipping method. During the replacement of the slag-blocking mechanism, whether placing the used mechanism on the transport and storage device or lifting the new mechanism from it, the side lifting rings of the slag-blocking mechanism are located on the left and right sides of the locking assembly and are a certain distance away, avoiding any interference from the lifting tools and hooks on the locking assembly's operation. The slag-blocking mechanism can be locked or loosened first using the hooks, and then the corresponding lifting tools can be operated. The lifting tools can be removed from the side lifting rings or hung on them, allowing the slag-blocking mechanism to be quickly and smoothly placed on the transport and storage device for transport, or quickly and smoothly lifted from the transport and storage device for replacement. The entire process is completed in about ten seconds, greatly improving the efficiency of lifting the slag-blocking mechanism on the transport and storage device, reducing the labor intensity of workers, and shortening the online replacement time of the slag-blocking mechanism.

[0017] 3. The locking assembly is arranged at a position right behind the fixing claw of the slag stopping mechanism on the top of the storage panel, so that the width of the storage panel is the same as that of the base assembly, which solves the problem of excessive width of the storage panel, improves the accuracy and working efficiency of the forklift when transporting the storage device for the front centering mechanism of the furnace. Meanwhile, the hook iron locks the slag stopping mechanism from the rear, which prolongs the service life of the hook iron and increases the reliability of locking the slag stopping mechanism, solves the influence of the flipping of the hook iron on the arrangement of the lifting rings on the side of the slag stopping mechanism, makes the position arrangement of the lifting rings on the side of the slag stopping mechanism more flexible and reliable, and allows more free selection of the size of the lifting rings.

[0018] 4. An included angle E between the storage panel and the rectangular steel pipe is set to 90° to 120°, preferably 100° to 110°. After the slag stopping mechanism with extremely high temperature is disassembled and lifted, the inclination angle and lifting height of the mechanism are basically close to the inclination angle and height of the storage panel, ensuring that the lifting posture and height of the slag stopping mechanism are basically unchanged, so that the slag stopping mechanism can be quickly and stably placed on the transportation and storage device and closely attached to the storage panel, which shortens the online replacement time of the slag stopping mechanism.

[0019] 5. An included angle E between the storage panel and the rectangular steel pipe is set to be between 90° and 120°. When replacing the slag stopping mechanism online, refractory mortar can be spread on the slide boss of the slag stopping mechanism to be replaced (which has been locked on the transportation and storage device) in advance, which saves the time for spreading refractory mortar on the slide boss before lifting and installing the slag stopping mechanism during online replacement, and shortens the online replacement time of the slag stopping mechanism by 10% to 20%.

[0020] 6. A horizontal transverse plate is arranged behind the storage panel, so that the horizontal transverse plate and the supporting side plates are connected to form a "冂"-shaped support behind the storage panel, and a locking assembly is arranged above the horizontal transverse plate, so that the inner vertical plate and the outer vertical plate are respectively connected with the storage panel and the horizontal transverse plate, which improves the structural firmness of the mechanism transportation and storage device and the safety during transportation.

[0021] The present invention completes the locking or releasing operation of the slag stopping mechanism on the transportation and storage device through horizontal pushing and pulling of the push-pull handle in the push-pull sleeve and forward and backward flipping of the hook iron. The locking assembly is arranged right behind the fixing claw of the slag stopping mechanism on the top of the storage panel, which avoids the influence of the spreader and hook on the flipping operation of the hook iron during the hoisting of the slag stopping mechanism, solves the influence of the flipping of the hook iron on the arrangement of the lifting rings on the side of the slag stopping mechanism, makes the position arrangement of the lifting rings on the side of the slag stopping mechanism more flexible and reliable, and allows more free selection of the size of the lifting rings. A waist-shaped hole is opened above the storage panel, and the horizontal transverse plate, the supporting side plates and the storage panel are connected to form a "冂"-shaped structure, which improves the structural strength of the mechanism transportation and storage device and the safety during transportation. The invention has simple operation, is safe and reliable, greatly improves the working efficiency of hoisting the slag stopping mechanism on the transportation and storage device and the safety during transportation, reduces the labor intensity of workers, and shortens the online replacement time of the slag stopping mechanism.

[0025] Example 1, see appendix to the instruction manual. Figure 1-9 A horizontal push-pull and front-and-back tilting converter slag-blocking mechanism 40 transport and storage device includes a base assembly, a storage panel 20 assembly, supporting side plates 30, and a storage locking assembly. The storage panel 20 assembly mainly consists of a storage panel 20 and positioning columns 21 arranged side by side at the bottom of the storage panel 20. The storage panel 20 is inclinedly positioned above the base assembly. Supporting side plates 30 are provided on both sides of the storage panel 20 and between the two ends of the base assembly, connecting the storage panel 20 to the base assembly. The storage locking mechanism mainly consists of a horizontal plate 31 and two locking components, and is located on top of the storage panel 20. The horizontal plate 31 connects the storage panel 20 and the two supporting side plates 30. The side plates 30 are connected together, and two locking components are respectively arranged at both ends of the horizontal plate 31. The locking components mainly consist of hook 63, inner vertical plate 60, outer vertical plate 61, push-pull sleeve 65465, rotating pin 64, and push-pull handle 62262. The inner vertical plate 60 and outer vertical plate 61 are respectively fixed between the horizontal plate 31 and the storage panel 20. The rotating pin 64 passes through the outer vertical plate 61, hook 63, and inner vertical plate 60 in sequence, rotatably connecting the hook 63 between the inner vertical plate 60 and the outer vertical plate 61. The push-pull sleeve 65465 is fixed to the outer vertical plate 61 with screws. The push-pull handle 62262 is slidably fitted inside the push-pull sleeve 65465.

[0026] The base assembly is a rectangular frame composed of rectangular steel pipes 10 and channel steel 11. The rectangular steel pipes 10 have rectangular fork holes 101 inside, which facilitates the lifting and transportation of the mechanism's transport and storage device by forklifts.

[0027] The supporting side plate 30 is made of steel plate or other profiles, and is trapezoidal or other types in shape. It is preferred to be a trapezoidal steel plate to increase the structural strength of the transport and storage device.

[0028] The storage panel 20 is provided with a fully enclosed waist-shaped hole 201 or a semi-open U-shaped hole above it. Preferably, the shape is a fully enclosed waist-shaped hole 201, which is symmetrically arranged and located above the positioning post 21.

[0029] Both the front and rear ends of the hook iron 63 are L-shaped, and the whole is in a "冂" shape. The inner side surface of the front hook body of the hook iron 63 serves as the locking surface 634 of the hook iron 63, the outer side surface of the rear hook body serves as the push-pull locking surface 633, a turning stop surface 632 is provided at the edge above the push-pull locking surface 633, and a rotating hole C 631 is provided at the lower end of the rear hook body; the slag stopping mechanism 40 is hooked by the locking surface 634 of the hook iron 63, and the push-pull rod 621 is pushed to the rear of the push-pull locking surface 633, then the slag stopping mechanism 40 can be locked for storage or transportation. The hook iron 63 is rotated backward, and it automatically stops when the turning stop surface 632 touches the horizontal transverse plate 31, so that the rotation angle of the hook iron 63 is controlled within a range of 160°.

[0030] The push-pull sleeve 65465 is mainly composed of a connecting flange 651 and a sleeve 654, a through push-pull hole C 652 is arranged in the middle, threaded holes 653 are arranged around the connecting flange 651, an L-shaped push-pull groove is arranged on the upper side wall of the sleeve 654. The push-pull handle 62262 is composed of a push-pull rod 621 and a handle 622 which are connected integrally. When the handle 622 is located at the end position 655 of the push-pull groove, the push-pull rod 621 retracts into the outer vertical plate 61, and the hook iron 63 rotates freely along the rotating pin shaft 64. When the handle 622 is located at the starting position 656 of the push-pull groove, the push-pull rod 621 extends out to the inner vertical plate 60 and blocks behind the push-pull locking surface 633 to lock the hook iron 63.

[0031] A rotating hole A 601 and a push-pull hole A 602 are arranged on the inner vertical plate 60, a rotating hole B 611, a push-pull hole B 612 and a fixing bolt hole 613 are arranged on the outer vertical plate 61, the fixing bolt hole 613 and the threaded hole 653 of the push-pull sleeve 65465 are arranged concentrically, the rotating hole A 601, the rotating hole B 611 and the rotating hole C 631 have the same size and corresponding positions, the rotating pin shaft 64 is T-shaped and passes through the outer vertical plate 61, the hook iron 63 and the inner vertical plate 60 in sequence, so that the hook iron 63 turns back and forth along the rotating pin shaft 64. The push-pull hole A 602, the push-pull hole B 612 and the push-pull hole C 652 have the same size and corresponding positions, so that the push-pull handle 62262 always slides between the push-pull holes, which greatly facilitates on-site operation, improves work efficiency and reduces the labor intensity of workers.

[0032] In the two locking assemblies, the outer vertical plates 61 and the push-pull sleeves 65465 are completely symmetrical left and right, and the hook irons 63, the inner vertical plates 60, the rotating pin shafts 64 and the push-pull handles 62262 are completely identical left and right, which reduces the number of spare parts for the locking assemblies and lowers the production cost.

[0033] The included angle E between the storage panel 20 and the rectangular steel pipe 10 is 90° to 120°, which ensures that the hoisting posture and height of the slag stopping mechanism 40 are basically unchanged, so that the slag stopping mechanism 40 can be quickly and stably placed on the transportation and storage device and closely attached to the storage panel 20, shortening the on-line replacement time of the slag stopping mechanism 40.

[0034] The usage process and principle of this invention are as follows: The converter uses a sliding plate slag-blocking process for tapping steel. After a certain service life, the slag-blocking mechanism 40 must be replaced as a whole. When replacing the slag-blocking mechanism 40 in the horizontal converter online, (1) the used slag-blocking mechanism 40 is removed and transported away from the site: After removing the red-hot slag-blocking mechanism 40 that has just been blocked from the tapping port, the slag-blocking mechanism 40 is quickly lifted and moved above the transport and storage device. After aligning the mechanism pin hole 412 with the positioning column 21 on the transport and storage device, the slag-blocking mechanism 40 is quickly lowered and pushed hard so that the bottom surface 401 of the mechanism is pressed tightly against the transport and storage device. Place the slag-blocking mechanism 40 on the storage panel 20 of the storage device, then gently push the hook 63 forward to flip it and hook it onto the slag-blocking mechanism 40. Push the handle 622 to the initial position 656 of the push-pull sleeve 65465 so that the push-pull rod 621 is fully extended and the hook 63 is locked. This will quickly lock the slag-blocking mechanism 40 onto the transport and storage device. At the same time, the male end of the slag-blocking mechanism 40 slide plate falls into the closed waist-shaped hole 201 of the storage panel 20. Finally, remove the lifting device from the side lifting ring 50 and use a forklift to transport the slag-blocking mechanism 40 and the transport and storage device away from the site. (2) Transporting and installing the new slag-blocking mechanism 40: After the forklift transports the new slag-blocking mechanism 40 to the transport and storage device and places it in place, install the new slag-blocking mechanism 40. After hanging the lifting device on the side lifting ring 50 of the slag-blocking mechanism 40, pull the handle 622 to the end position 655 of the push-pull groove of the push-pull sleeve 65465 so that the push-pull rod 621 is fully retracted. Move the hook iron 63 to make it flip backward, and the slag-blocking mechanism 40 can be quickly released. Finally, lift the lifting device to lift the slag-blocking mechanism 40 from the transport and storage device and move it to the steel outlet position to complete the replacement operation of the new slag-blocking mechanism 40. The online replacement of the entire slag-blocking mechanism 40 can be completed. (3) During the dismantling and replacement of the above-mentioned slag-blocking mechanism 40, the hooking and unhooking operation of the lifting tool on the side lifting ring 50 has no effect on the operation of the hook iron 63 and the push-pull handle 62262 in the locking assembly. The slag-blocking mechanism 40 is locked or released on the transport and storage device by the horizontal push and pull of the push-pull handle 62262 and the forward and backward flipping of the hook iron 63. The horizontal push and pull action of the push-pull handle 62262 is always completed inside the push-pull sleeve 65465, which greatly facilitates the on-site operation. The process of locking or releasing the slag-blocking mechanism 40 only takes more than ten seconds, which improves work efficiency and reduces the labor intensity of workers.
