Technical Field

[0001] The invention relates to the transportation of molten iron tanks, in particular to a flip-over cover-added molten iron tank car. Background Art

[0002] In the metallurgical industry, the molten iron produced in the ironmaking process is generally stored in a molten iron tank and transported to the next process by tank trucks. During transportation, the molten iron tank is generally open, which can easily cause the heat of the molten iron to dissipate, the molten iron temperature to drop, and increase the energy consumption of the next process; at the same time, if the molten iron tank is open, it may cause safety accidents if the molten iron splashes, especially during long-distance transportation on rainy days. Once the molten iron contacts rainwater, it may explode, causing serious safety accidents. Summary of the invention

[0004] The present invention is achieved in that:

[0005] An embodiment of the present invention provides a flip-up cover for a molten iron ladle truck, comprising a vehicle body having a molten iron ladle placement position, a cover body capable of sealing the opening of the molten iron ladle, and a cover-opening mechanism for controlling the cover body to cover or uncover the opening of the molten iron ladle, wherein the cover-opening mechanism is mounted on the vehicle body, the cover body comprises a left cover and a right cover capable of being spliced ​​with the left cover to seal the opening of the molten iron ladle, the cover-opening mechanism comprises a driving assembly for driving the left cover and the right cover to rotate to seal or open the opening of the molten iron ladle, and the rotation paths of the left cover and the right cover are located on opposite sides of the splicing.

[0006] Furthermore, the driving assembly includes two gears meshing with each other and a driving member driving one of the gears to rotate, wherein one gear is connected and fixed to the right cover, and the other gear is connected and fixed to the left cover, and the rotation axes of the two gears are both horizontally arranged.

[0007] Furthermore, the driving member comprises a hydraulic cylinder, one end of the hydraulic cylinder is hinged to the vehicle body, and the other end of the hydraulic cylinder is hinged to one of the gears.

[0008] Furthermore, two groups of limit blocks are arranged on the vehicle body, corresponding to the right cover and the left cover respectively, and one group of the limit blocks is located at the end of the rotation path when the right cover is opened, and the other group of the limit blocks is located at the end of the rotation path when the left cover is opened.

[0009] Furthermore, the limit blocks all have a support surface which is arranged horizontally and is used to support the right cover or the left cover after opening.

[0010] Furthermore, a rain shield is provided on the right cover, and the rain shield extends along the length direction of the splicing surface of the right cover, and the rain shield is located directly above the splicing surface of the right cover.

[0011] Furthermore, the rain shield includes a supporting portion and a cover portion, the supporting portion extending upward from the upper surface of the right cover, the cover portion being located at the top of the supporting portion and having an inverted U-shaped groove, the inverted U-shaped groove extending along the length direction of the splicing surface of the right cover, and the inverted U-shaped groove being located directly above the splicing surface of the right cover.

[0012] Furthermore, the upper surface of the right cover and the upper surface of the left cover are both inclined surfaces inclined downward in a direction away from the splicing position.

In addition, since the rotation paths of the left cover and the right cover are located on the opposite sides of the joint of the two, it means that after the cover is opened, the left cover and the right cover are respectively located on the opposite sides of the molten iron tank, which is beneficial to the space arrangement on the vehicle body.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 The embodiment of the present invention provides a flip-up lidded molten iron ladle truck, comprising a car body 1, which is the foundation of the molten iron ladle truck, and has a molten iron ladle 2 placement position on it, and a running wheel 11 is arranged below it, and the molten iron ladle truck can be driven to move by the running wheel 11. Usually, the molten iron ladle 2 is located in the middle position of the car body 1, and a support column 12 is arranged at the bottom corresponding to the installation position of the molten iron ladle 2. The support column 12 can adopt a hydraulic cylinder. When the car body 1 moves, these support columns 12 retract, and their bottoms are higher than the bottoms of the running wheels 11. The support columns 12 will not affect the normal movement of the car body 1. When the car body 1 stops, the support columns 12 extend. At this time, the support columns 12 serve as the main supporting components of the car body 1; the molten iron ladle truck also includes a cover body 4 and a lid-uncovering mechanism 3, wherein the cover body 4 is mainly used to flexibly block the opening of the molten iron ladle 2, and the lid-uncovering mechanism 3 is used to control the active blocking action of the cover body 4, and the lid-uncovering mechanism 3 is arranged on the car body 1. The structure of the cover body 4 and the cover-opening mechanism 3 is detailed, wherein the cover body 4 includes a left cover 41 and a right cover 42, the left cover 41 and the right cover 42 can be spliced ​​into a complete cover body 4, and the two can be understood as half of the cover body 4. For example, when the cover body 4 is circular, the left cover 41 and the right cover 42 are both semicircular, and the splicing position of the two is located on one of the diameters of the cover body 4; the cover-opening mechanism 3 includes a driving assembly 31, and the left cover 41 and the right cover 42 are both driven to rotate by the driving assembly 31, and the rotation paths of the left cover 41 and the right cover 42 are located on opposite sides of the splicing. Specifically, when the left cover 41 and the right cover 42 are close to each other, the left cover 41 and the right cover 42 can be spliced ​​into a complete cover body 4, at which time the open mouth of the molten iron tank 2 is blocked, and the covering of the molten iron tank 2 is completed, and when the left cover 41 and the right cover 42 are rotated and separated, the cover-opening action of the molten iron tank 2 is realized. In the present invention, when the molten iron tank 2 is placed on the vehicle body 1, the left cover 41 and the right cover 42 can be controlled by the driving component 31 to rotate relative to each other until the two are spliced ​​into a complete cover body 4, and at this time, the opening of the molten iron tank 2 can be blocked to realize the covering process, and when the molten iron in the molten iron tank 2 needs to be processed, the left cover 41 and the right cover 42 can be controlled by the driving component 31 to rotate back to the specified position, and the molten iron tank 2 is opened to realize the uncovering process. In the above process, the left cover 41 and the right cover 42 both realize the uncovering action by rotating, which is more convenient, and after uncovering, the left cover 41 and the right cover 42 are respectively located on the opposite sides of the molten iron tank 2, which is conducive to the storage space of the cover body 4 after uncovering, and will not increase the structure of the vehicle body 1 additionally.

[0022] See also Figure 2 , the above embodiment is refined, specifically the structure of the driving assembly 31 is refined, which includes two gears 311 and a driving member 312, wherein the two gears 311 are externally meshed, and the driving member 312 can drive one of the gears 311 to rotate, and then the gear 311 drives the other gear 311 to rotate synchronously, and the rotation directions are opposite. In addition, one of the gears 311 is connected and fixed to the right cover 42, that is, the gear 311 can drive the right cover 42 to rotate synchronously around the same rotation axis, and the other gear 311 is connected and fixed to the left cover 41, and the gear 311 can drive the left cover 41 to rotate synchronously around the same rotation axis. In this embodiment, the left cover 41 and the right cover 42 can be controlled to rotate synchronously by the same driving member 312, which is more convenient. The two gears 311 use the same specifications, which can ensure that the left cover 41 and the right cover 42 move synchronously, and the movement speed and angle are the same, ensuring that the left cover 41 and the right cover 42 are always aligned. A hydraulic cylinder can be used for the driving member 312, one end of which is hinged to the vehicle body 1, and the other end of which is hinged to one of the gears 311. Specifically, a cylinder seat 13 is provided on the vehicle body 1, and the cylinder body of the hydraulic cylinder is hinged to the cylinder seat 13. Each gear 311 is installed between two bearing seats 313, and the rotating shaft 314 of each gear 311 is rotatably installed on the two bearing seats 313, and a transmission plate 315 extending in the radial direction is provided on the rotating shaft 314. The piston of the hydraulic cylinder is rotatably connected to the transmission plate 315, and the transmission plate 315 and the rotating shaft 314 can be pushed to rotate around the rotating axis by the extension and contraction of the hydraulic cylinder. For the left cover 41 and the right cover 42, both have a connecting plate 43, and the connecting plate 43 extends from the edge of the left cover 41 or the right cover 42 to the corresponding rotation axis. Specifically, the left cover 41 and the right cover 42 each have two connecting plates 43 arranged opposite to each other, and the above-mentioned molten iron tank 2 is placed between the two connecting plates 43. In addition, the above-mentioned gear 311 and the bearing seat 32 are both located on the same side of the molten iron tank 2 placement position, and the bearing seat 32 should also be provided on the other side of the molten iron tank 2 placement position. One of the connecting plates 43 of the left cover 41 or the right cover 42 extends to The bearing seat 32 is rotatably connected to the bearing seat 32, which is the follower side of the left cover 41 or the right cover 42, and the other connecting plate 43 is connected to the rotating shaft 314 of the corresponding gear 311, which is the driving side of the left cover 41 or the right cover 42. The driving side of the left cover 41 or the right cover 42 drives it to rotate around the rotation axis, and the following side rotates synchronously, which can ensure the stability of the left cover 41 or the right cover 42 during rotation, and after the left cover 41 and the right cover 42 cover the molten iron tank 2, the following side and the active side simultaneously support the left cover 41 or the right cover 42.

[0023] In addition, since the masses of the left cover 41 and the right cover 42 are relatively large, during the rotation process, especially when they are brought together to seal the open mouth of the molten iron tank 3, the collision between the left cover 41 and the right cover 42 should be minimized. Therefore, a displacement sensor is added between the left cover 41 and the right cover 42. For example, a proximity switch 47 is provided on the left cover 41, and a sensing member 48 matching the proximity switch 47 is provided on the right cover 42. The sensing member 48 is an iron stop, and the proximity switch 47 is electrically connected to the drive component, specifically, it is electrically connected to the hydraulic station corresponding to the hydraulic cylinder. When the proximity switch 47 and the sensing member 48 reach the sensing distance, the proximity switch 47 sends a signal to the hydraulic station, and the hydraulic station stops supplying oil to the hydraulic cylinder and locks the hydraulic cylinder, so that the hydraulic cylinder stops moving and keeps the extended length unchanged, thereby avoiding a large collision during the closing process of the left cover 41 and the right cover 42, and at the same time can ensure that the left cover 41 and the right cover 42 are always in a closed state during transportation. Of course, when it is necessary to uncover the molten iron tank 3, the hydraulic station will cancel the signal generated by the proximity switch 47, and the hydraulic station will start to supply oil to the hydraulic cylinder, which will retract and simultaneously drive the left cover 41 and the right cover 42 to rotate in the opposite direction and move away.

[0024] In a preferred embodiment, the hydraulic cylinder also has a buffering function. When the left cover 41 and the right cover 42 rotate relative to each other and move closer, the buffering function of the hydraulic cylinder is activated, and the extension action is slowed down, which can further avoid a large collision between the left cover 41 and the right cover 42.

[0025] See again Figure 1 , the above embodiment is further optimized, and two groups of limit blocks 14 are further provided on the vehicle body 1, corresponding to the right cover 42 and the left cover 41 respectively, one group of limit blocks 14 is located at the end of the rotation path when the right cover 42 is in the open state, and the other group of limit blocks is located at the end of the rotation path when the left cover 41 is in the open state. In the present invention, the rotation paths of the left cover 41 and the right cover 42 correspond to two ends, and the state when the two are spliced ​​into a complete cover body 4 is defined as the beginning of the rotation path. When the two rotate to the end of the rotation path, the corresponding limit blocks 14 of the two will limit their continued rotation, that is, limit the maximum rotation angle of the left cover 41 and the right cover 42, and achieve the purpose of mechanical limit.

[0026] Furthermore, the stopper 14 has a support surface 141, which is horizontally arranged and located on the rotation path of the left cover 41 or the right cover 42. When the left cover 41 and the right cover 42 rotate to the corresponding stopper 14, at least part of the structure of the left cover 41 and the right cover 42 is located on the support surface 141 of the corresponding stopper 14. At this time, the support surface 141 can restrict the left cover 41 or the right cover 42 from continuing to rotate, and can also support the left cover 41 or the right cover 42, so that the state of the left cover 41 and the right cover 42 remains stable after the cover is opened. For this structural form, a displacement sensor should also be arranged between the stopper 14 and the corresponding left cover 41 or the right cover 42. When the left cover 41 or the right cover 42 approaches the corresponding stopper, the retraction action of the hydraulic cylinder slows down, so as to avoid a large collision between the left cover 41 or the right cover 42 when the left cover 41 or the right cover 42 flips to the corresponding stopper 14. In addition, a buffer structure can also be arranged on the support surface 141 to further reduce the collision between the two.

[0027] See 1 again and Figure 2 Furthermore, a rain cover 44 structure is also provided on the right cover 42, and the rain cover 44 extends along the length direction of the splicing surface of the right cover 42, and the rain cover 44 is located directly above the splicing surface of the right cover 42. In the present invention, when the right cover 42 and the left cover 41 are spliced ​​into a complete cover body 4, a splicing seam is formed at the splicing surface of the right cover 42 and the left cover 41. Therefore, in this embodiment, a rain cover 44 structure is provided, and when the right cover 42 and the left cover 41 are spliced, the rain cover 44 is located directly above the splicing seam, thereby forming a shielding effect on the splicing seam. The structure of the rain shield 44 is detailed, and includes a support portion 441 and a cover portion 442. The support portion 441 is formed by extending upward from the upper surface of the right cover 42, or is directly fixed on the upper surface of the right cover 42. The cover portion 442 is located at the top of the support portion 441, and has an inverted U-shaped groove, which extends along the length direction of the splicing surface of the right cover 42, and the inverted U-shaped groove is located directly above the splicing surface of the right cover 42. After the right cover 42 and the left cover 41 are spliced, one end of the inverted U-shaped groove is located on one side of the right cover 42, and the other side extends to one side of the left cover 41, which can cover the entire splicing seam. In addition, the end of the inverted U-shaped groove extends toward the left cover 41 and is close to the upper surface of the left cover 41, so that the gap between the inverted U-shaped groove and the upper surface of the left cover 41 is relatively small, which can further reduce the possibility of rainwater entering the molten iron tank 2 through the splicing seam.

[0028] Continuing to optimize the above embodiment, the upper surface of the right cover 42 and the upper surface of the left cover 41 are both inclined surfaces inclined downward in the direction away from the splicing position, that is, the upper surfaces of the right cover 42 and the left cover 41 have a certain slope, and the splicing surface is the high end. When rainwater falls on the upper surface of the right cover 42 or the left cover 41, it will flow along the corresponding inclined direction in the direction away from the splicing surface, thereby further preventing rainwater from entering the molten iron tank 2 through the splicing seam.

[0029] See also Figure 1 as well as Figure 2 In addition, the cover body 4 has an annular skirt 45 structure, which is formed by extending downward from the outer side of the cover body 4. Specifically, the side surfaces (except the joint surface) of the left cover 41 and the right cover 42 are formed with the skirt 45 structure. When the left cover 41 and the right cover 42 are square, the three sides thereof have the skirt 45 structure, and when the left cover 41 and the right cover 42 are circular, the outer circumferential surface thereof has the skirt 45 structure. The so-called skirt 45 structure is actually the retaining edge provided by the cover body 4. When the cover body 4 covers the molten iron tank 2, the bottom end of the skirt 45 is lower than the opening of the molten iron tank 2 by a certain distance, which can surround the opening of the molten iron tank 2, and then can form a shield for the sealing part between the cover body 4 and the molten iron tank 2, so as to prevent rainwater from entering the molten iron tank 2 from the edge of the cover body 4. In addition, the above-mentioned connecting plate 43 can be used as a part of the skirt structure of the left cover 41 or the right cover 42.

[0030] See again Figure 1 as well as Figure 2 Furthermore, a heat insulating material layer 46 is provided on the inner side of the left cover 41 and the right cover 42, that is, the left cover 41 and the right cover 42 are at least a two-layer structure, the outer layer has a certain strength, and the inner layer is the heat insulating material layer 46, which can not only prevent the outer layer from being overheated and affecting its strength, but also further reduce the heat loss of molten iron.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
