Description

Technical Field

[0001] The present invention relates to the field of torpedo tanks, and in particular to a transportation system. Background Art

[0002] Torpedo tank cars are currently key equipment for transporting molten iron between the blast furnace and the steelmaking plant in steel plants. However, due to the lack of a cap on the torpedo tank mouth, smoke and dust escape and the molten iron loses its temperature, polluting the on-site environment and causing the molten iron to lose its temperature. Therefore, the existing practice is to add a cap to the filling port of the torpedo tank. However, the temperature of the tank mouth is relatively high, making manual capping inconvenient.

[0003] For example, the torpedo tank cover opening and closing device with application number 202210229793.9 includes a driving mechanism and a sliding lifting mechanism. The driving mechanism includes a mounting column and a driving arm arranged on the mounting column; the sliding lifting mechanism is used to be arranged on the torpedo tank truck; the sliding lifting mechanism includes a fixing seat arranged on the torpedo tank truck and a connecting rod assembly arranged on the fixing seat, one end of the connecting rod assembly is connected to the tank cover of the torpedo tank truck, and the driving arm is connected to the connecting rod assembly to drive the connecting rod assembly to drive the tank cover to lift and detach from the torpedo tank truck; the above-mentioned torpedo tank truck cover opening and closing device, the connecting rod assembly is a connecting rod mechanism, which is driven by the driving arm, and the end connected to the tank cover can be lifted and detached, so that the tank cover connected to the connecting rod assembly can be lifted up and detached from the tank mouth, or brought down to cover the tank mouth, without the need for manual opening and closing of the cover, which not only saves manpower and material resources but also eliminates the safety hazards caused by manual covering;

[0004] Due to the different production capacities of factories, the specifications of torpedo tanks vary. For example, small ones include 1.5 cubic meters and 2 cubic meters, while large ones include 2.5 cubic meters and even 3 cubic meters. Large torpedo tanks have larger mouth diameters and the corresponding tank covers are heavier (about 1.5 tons). Therefore, when the torpedo tank cover opening and closing device is applied to large tank covers, the reliability is lower due to the overall weight of the tank covers. Summary of the Invention

DETAILED DESCRIPTION

[0031] To facilitate those skilled in the art to understand the present invention, specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0033] First, the application scenario of this application is introduced: in the metallurgical field, molten iron is generally transported by torpedo tank trucks 4. Since the torpedo tank mouth is not covered, smoke and dust are emitted and the molten iron temperature is lost, which not only pollutes the on-site environment, but also causes the molten iron temperature to lose; the large tank cover is heavy and the torpedo tank mouth temperature is high, so it is impossible to manually cover it; Figure 1 As shown, the present invention provides a transportation system, comprising a covering unit 1 arranged in the iron-casting area and a uncovering unit 2 arranged in the iron-receiving area, and a torpedo tank unit 3 arranged between the iron-casting area and the iron-receiving area for transporting molten iron, wherein a track is provided between the iron-casting area and the iron-receiving area, and the torpedo tank unit 3 moves between the iron-casting area and the iron-receiving area via the track to transport the molten iron; the torpedo tank unit 3 comprises an existing torpedo tank car 4 and a lifting tank cover 5, and the torpedo tank car 4 is provided with a torpedo tank; in the iron-casting area, molten iron is added to the torpedo tank, and the lifting tank cover 5 is lifted by the covering unit 1 and then covered on the tank mouth of the torpedo tank; in this way, smoke is not leaked during the entire transportation process and a heat preservation effect is achieved; after the torpedo tank car 4 transfers the molten iron to the iron-receiving area, the lifting tank cover 5 is lifted by the uncovering unit 2 to uncover it; as shown Figure 2As shown, the covering unit 1 includes a first suspension arm 6 and a lifting member 7 arranged at the lifting part of the first suspension arm 6, wherein the first suspension arm 6 is arranged beside the track in the iron-making area, and its column part is fixed to the ground; the installation of the first cantilever crane must be allowed to take the installation position into consideration and must not interfere with the operation and safety of the vehicle. At the same time, when excavating civil engineering, it is also necessary to consider whether there are underground pipelines and cables at the currently selected location; the weight of a large-scale lifting tank cover 5 is generally above 1.5 tons, so the first cantilever crane cantilever adopts a maximum lifting weight of 2.8 tons, a turning radius of 5 meters, and a control mode of cable and remote control that is convertible; at the same time, the uncovering unit 2 includes a second suspension arm and a lifting member 7 arranged at the lifting part of the second suspension arm, wherein the second suspension arm is arranged beside the track in the iron-receiving area, and its column part is fixed to the ground; the large-scale lifting tank cover 5 is hoisted by the first cantilever crane and the second suspension arm, and the structure is more reliable than the existing hydraulic push rod method.

[0034] The lifting member 7 can be a hook, which is used to take and put the cover during the lifting process; the tank cover is lifted by the hook, and the simple hook lacks a locking structure, which poses a safety hazard during the lifting process; at the same time, the torpedo tank is filled with molten iron, and the temperature of its tank mouth is relatively high; manual operation is carried out in a relatively poor operating environment; Figure 4As shown, the lifting member 7 includes a positioning member 9 with an inverted U-shaped cross-section, and a pressure plate 10 is fixed to the lower side of the positioning member 9 through a locking member, and a channel is formed in the center of the pressure plate 10; grooves 11 are provided on the left and right sides of the positioning member 9, and the linkage block 12 is a square plate structure, with sliding columns 14 corresponding to the grooves 11 on both sides, and the sliding columns 14 slide in the grooves 11; the linkage block 12 is provided with a receiving groove 13 with a circular cross-section, and a linkage shaft is vertically provided in the center of the receiving groove 13; the linkage The shaft passes through the channel of the pressure plate 10 and is welded to the lifting hook 15. A compression spring 16 is passed through the sliding column 14. An ear plate 17 is provided on the opposite side of the pressure plate 10 and the lifting hook 15. An ear plate shaft 18 is welded and fixed between the ear plates 17. The rotating rod 19 rotates with the ear plate shaft 18 through a torsion spring. The rotating rod 19 is linear and has a rotating channel on it. A rope rod 20 is provided on one side of the two rotating rods 19. One end of the wire rope 21 is fixed to the rope rod 20. The other end of the wire rope 21 passes through The rotating guide wheel 22 is fixed to the upper side of the linkage block 12. The guide wheel 22 is located on the upper side of the linkage block 12 and rotates with both sides to play the role of reversing and transmitting tension. A clamping rod 33 is provided on the other side of the rotating rod 19. When in use, the lifting hook 15 is hooked on the upper side of the lifting tank cover 5. The linkage block 12 slides toward the side close to the pressure plate 10, the wire rope 21 pulls the rope rod 20, and the rotating rod 19 rotates along the ear plate shaft 18. When the linkage block 12 contacts the pressure plate 10, the clamping rod 33 is in contact with the lifting hook 15. The hooks 15 contact to form a closed space; adaptive locking is performed; the safety hazard in the lifting process is solved. After the tank cover is placed at the tank mouth position, the linkage block 12 slides to the side away from the pressure plate 10, and under the action of the torsion spring, the rotating rod 19 rotates along the fixed axis away from the lifting hook 15 to restore the initial state; after the lifting tank cover 5 is lowered, the clamping rod 33 contacts the lifting hook 15 to form a closed space that opens; that is, the safety hazard in the lifting process is solved; at the same time, the manual locking process is omitted.

[0035] like Figure 8As shown, the torpedo tank car 4 is provided with a torpedo tank, which includes a tank body 23, an elliptical tank mouth provided on the upper side of the tank body 23, and a flange 24 extending outwardly on the tank mouth; an arc-shaped platform 25 is provided on the outer side of the tank mouth, and the upper side of the arc-shaped platform 25 is a flat structure; the lower side of the arc-shaped platform 25 is formed with an arc surface corresponding to the torpedo tank, and the lower arc surface of the arc-shaped platform 25 is used to fix the torpedo tank, and the arc-shaped platform 25 has a platform opening 26 corresponding to the tank mouth, and the flange 24 extends from the platform opening 26; the flange 24 of the tank mouth adopts an elliptical shape, which is convenient for collecting molten iron during pouring; but in the process of hoisting the tank cover 5 and closing it with the flange 24, if an elliptical structure corresponding to the shape is adopted, it is inconvenient to align the hoisting tank cover 5 with the flange 24, and manual alignment is required (that is, the length direction of the elliptical hoisting tank cover 5 needs to be aligned with the length direction of the tank mouth); in order to solve this problem, as Figure 11 As shown, the lifting tank cover 5 adopts a circular structure, so that no matter what angle the lifting tank cover 5 is at, it can be consistently covered with the flange 24 of the elliptical structure; a hanging ring 8 is provided on the upper side of the lifting tank cover 5, and the outer edge of the lifting tank cover 5 is turned inward toward the lower side; the height of the outer edge is consistent with the flange 24, and a plurality of hooks 27 are provided on the inner side of the lifting tank cover 5. A fire-resistant layer 28 with a thickness of 50-60 mm is provided on the inner side of the lifting tank cover 5 to ensure that the fire-resistant layer 28 is firmly fixed; when the lifting tank cover 5 is covered on the flange 24, the lower side of the outer edge is in contact with the upper side of the arc platform 25; the lifting tank cover 5 is sealed to prevent the overflow of smoke;

[0036] The torpedo tank car 4 has a torpedo tank. The temperature of the part of the torpedo tank near the tank mouth is relatively low. When pouring out the molten iron, part of the molten iron cools down at the tank mouth and forms a wall. Over time, the wall and iron slag continue to accumulate, causing the pouring side of the tank mouth to be uneven. This makes it easy for the molten iron to not be able to gather or splash when pouring out. Figure 10 As shown, a mounting notch 29 is provided on one side of the flange 24, and a mounting seat 30 is provided on the outer edge of the mounting notch 29; a detachable replacement part 31 is provided on the cut surface notch; the replacement part 31 includes a horizontal section and a vertical section, the vertical section is an arc-shaped extension, and corresponds to the structure of the flange 24; an arc-shaped crescent-shaped recess 32 is formed on the upper side of the vertical section; the horizontal section of the replacement part 31 is fixed to the mounting seat 30 by a locking part; the rotation of the torpedo tank is controlled to discharge the molten iron in the torpedo tank along the crescent-shaped recess 32; after a long time, the wall hanging and iron slag continue to accumulate, causing the crescent-shaped recess 32 to be uneven; that is, the replacement part 31 is replaced as a whole; thereby solving the problem of molten iron splashing caused by the uneven discharge side.

[0037] Unless otherwise specified above, the fixing methods generally used by those skilled in the art include welding, nesting, or threaded fixing.
