Description

Technical Field

[0001] This utility model belongs to the field of torpedo tanker insulation technology, specifically relating to an automatic torpedo tanker opening device. Background Technology

[0002] Torpedo-type ladle cars are key equipment for transporting molten iron in steel enterprises. Their open ladle design causes severe heat loss during transportation, resulting in a rapid drop in the temperature of the molten iron and the generation of a large amount of harmful fumes, which pollutes the environment.

[0003] Patent application number 202210229793.9 discloses a torpedo tank car cover opening and closing device, including a drive mechanism and a sliding lifting mechanism. In this device, the linkage assembly is a linkage mechanism driven by a drive arm. One end of the linkage assembly connected to the tank cover can be raised and lowered, allowing the tank cover connected to the linkage assembly to be lifted off the tank opening or lowered to cover it. This eliminates the need for manual opening and closing, saving manpower and resources, increasing efficiency, and eliminating the safety hazards associated with manual cover application.

[0004] However, in the existing technology, the can lid is only flipped on one side by a hinged linkage mechanism. This opening and closing method requires a large vertical space to ensure that the can lid is far away from the can opening, which is difficult to implement in areas where the height of the factory is limited. In addition, the center of gravity of the can lid shifts significantly during the opening process of the rotary opening structure, which can easily cause uneven stress on the structure, and may cause the can lid to shake or even overturn, affecting the stability of the equipment. Utility Model Content

[0005] Based on the above-mentioned technical problems, the purpose of this utility model is to provide an automatic torpedo tank car opening device. This device uses a combination of lifting hydraulic cylinder, support base and electro-hydraulic push rod to realize the horizontal opening and closing operation of the tank cover. It can operate stably in the factory without vertical flipping space. Moreover, the guide component and clamping component guide and limit the structure of the tank cover, thereby avoiding the risk of tipping due to the center of gravity shift, thus ensuring the stability of the device.

[0006] The specific technical solution is as follows: An automatic lid-opening device for a torpedo tanker includes: a lifting hydraulic cylinder, a support base, a mounting shell, an electro-hydraulic actuator, a tank cover structure, a guide assembly, and a clamping assembly. The lifting hydraulic cylinder and the support base are both located on one side of the torpedo tanker, and the telescopic end of the lifting hydraulic cylinder and the top of the support base are rotatably connected to the mounting shell. An electro-hydraulic actuator is installed inside the mounting shell and connected to the tank cover structure. The guide assembly is located inside the mounting shell on both sides of the electro-hydraulic actuator and is in contact with the bottom surface of the tank cover structure. The clamping assembly is located on both sides of the mounting shell and is in contact with the top surface of the tank cover structure.

[0007] In addition, the automatic torpedo tanker opening device in the above-mentioned technical solution provided by this utility model may also have the following additional technical features: In the above technical solution, the can cover structure includes: a can cover, a sliding cover, and a reinforcing plate; one end of the sliding cover is connected to the telescopic end of the electro-hydraulic actuator, the other end of the sliding cover is connected to the can cover, and the top and bottom surfaces of the sliding cover are respectively attached to the guide assembly and the clamping assembly; both ends of the reinforcing plate are connected to the can cover and the sliding cover respectively.

[0008] In the above technical solution, the guide assembly includes six guide wheels, which are respectively arranged on both sides inside the mounting housing, and the bottom of the sliding cover is in contact with the guide wheels.

[0009] In the above technical solution, the clamping assembly includes six clamping rollers, which are respectively disposed on both sides of the top of the mounting housing, and the clamping rollers are in contact with the top of the sliding cover.

[0010] In the above technical solution, there are two lifting hydraulic cylinders and two support seats.

Detailed Implementation

[0017] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0018] An automatic lid-opening device for torpedo tank cars, such as Figure 1-5 As shown, the system includes: a lifting hydraulic cylinder 12, a support base 13, a mounting shell 14, an electro-hydraulic actuator 15, a tank cover structure, a guide assembly, and a clamping assembly. The lifting hydraulic cylinder 12 and the support base 13 are both located on one side of the torpedo tank car 10, and the telescopic end of the lifting hydraulic cylinder 12 and the top of the support base 13 are rotatably connected to the mounting shell 14. The mounting shell 14 contains the electro-hydraulic actuator 15, which is connected to the tank cover structure. The guide assembly is located inside the mounting shell 14, on both sides of the electro-hydraulic actuator 15, and is in contact with the bottom surface of the tank cover structure. The clamping assembly is located on both sides of the mounting shell 14 and is in contact with the top surface of the tank cover structure.

[0019] With the above structure, the lifting hydraulic cylinder 12 and the support base 13 form a double support structure, and with the horizontal telescopic drive of the electro-hydraulic push rod 15, the can cover 16 can be moved to open and close in a horizontal manner. No vertical flipping space is required, and it can operate stably in the factory without manual operation, thus avoiding the risks of burns and falls that may occur during manual opening and closing of the can.

[0020] When it is necessary to open the lid structure, the lifting hydraulic cylinder 12 lifts one end of the mounting shell 14 and the lid structure, so that the lid structure is separated from the mouth 11 of the torpedo tank car 10. The electro-hydraulic push rod 15 retracts the lid structure, so that the lid structure is away from the mouth 11 of the torpedo tank car 10, thereby facilitating the torpedo tank car 10 to receive molten iron.

[0021] When it is necessary to cover the can lid structure, the can lid structure is extended by the electro-hydraulic push rod 15, and the housing 14 and one end of the can lid structure are smoothly lowered by the lifting hydraulic cylinder 12, so that the can lid structure covers the can mouth 11 of the torpedo tank car 10, thereby sealing the can mouth 11 and preventing heat loss and harmful dust emission during the transportation of molten iron.

[0022] During the opening and closing of the lid, the guide component fits tightly against the bottom surface of the lid structure, ensuring smooth operation of the lid structure during retraction and extension. The clamping component dynamically constrains the top surface of the lid structure, preventing the lid structure from tipping over due to center of gravity shift during extension or retraction, thus ensuring the stability of the operation process.

[0023] Specifically, ground pole electronic tags are installed at key work points along the torpedo tank car 10's route, such as the blast furnace tapping point, the steelmaking workshop, and the entrance to the casting workshop. Card readers are also installed on the torpedo tank car 10. When the torpedo tank car 10 travels to a work point, the card reader automatically scans the electronic tag and transmits a signal through the control system to send instructions to the lifting hydraulic cylinder 12 and the electro-hydraulic push rod 15, thereby achieving automatic cover opening.

[0024] Specifically, the torpedo tanker 10 can be opened by manually operating the control button during maintenance.

[0025] Specifically, a ground charging pile is installed under the blast furnace to enable the torpedo car 10 to charge its onboard lithium battery when it is receiving iron in the blast furnace.

[0026] In an embodiment of this utility model, the can lid structure includes: a can lid 16, a sliding cover 17, and a reinforcing plate 18; one end of the sliding cover 17 is connected to the telescopic end of the electro-hydraulic push rod 15, the other end of the sliding cover 17 is connected to the can lid 16, and the top and bottom surfaces of the sliding cover 17 are respectively attached to the guide assembly and the pressing assembly; both ends of the reinforcing plate 18 are respectively connected to the can lid 16 and the sliding cover 17.

[0027] By ensuring that the bottom surface of the sliding cover 17 is tightly fitted with the guide assembly, the electro-hydraulic actuator 15 drives the cover plate to extend or retract smoothly. By ensuring that the top surface of the sliding cover 17 is tightly fitted with the clamping assembly, a dynamic limiting constraint is formed on the cover plate, which effectively suppresses the risk of tipping over due to the shift of the center of gravity during the extension process and ensures the stability of the equipment.

[0028] The connection strength between the can lid 16 and the sliding cover 17 is strengthened by reinforcing plate 18, thereby improving the overall rigidity and deformation resistance of the can lid structure.

[0029] In an embodiment of this utility model, the guide assembly includes six guide wheels 19, which are respectively disposed on both sides inside the mounting housing 14, and the bottom of the sliding cover 17 is in contact with the guide wheels 19.

[0030] By adopting a layout design with six guide wheels 19, the sliding cover 17 is subjected to uniform force during movement, avoiding the jamming and vibration problems caused by uneven force in the traditional two-point guiding method, and ensuring the smooth operation of the electro-hydraulic actuator 15 driving the cover plate to move.

[0031] In an embodiment of this utility model, the pressing assembly includes six pressing rollers 20, which are respectively disposed on both sides of the top of the mounting shell 14, and the pressing rollers 20 are in contact with the top of the sliding cover 17.

[0032] By setting six clamping rollers 20 and ensuring that the clamping rollers 20 are in close contact with the top of the sliding cover 17, a stable pressure is applied evenly by the clamping rollers 20 during the extension and retraction of the cover, effectively suppressing the risk of tipping over due to the shift of the center of gravity.

[0033] In the embodiments of this utility model, there are two lifting hydraulic cylinders 12 and two support seats 13.

[0034] By providing two lifting hydraulic cylinders 12 and two support bases 13, the stability of the support for the mounting shell 14 is improved.

[0035] In an embodiment of this utility model, two clamping rollers 20 are located at the front end of the mounting shell 14, and the remaining four clamping rollers 20 are located at the rear end of the mounting shell 14.

[0036] By arranging the six clamping rollers 20 such that two clamping rollers 20 are provided at the front end of the mounting housing 14 and four clamping rollers 20 are provided at the rear end of the mounting housing 14, this arrangement applies stronger stabilizing pressure to the rear end of the sliding cover 17, thereby avoiding the risk of the sliding cover 17 tipping over due to excessive extension of the area of ​​the sliding cover 17 beyond the mounting housing 14, which could cause the center of gravity to shift.

[0037] In an embodiment of this utility model, the mounting shell 14 is provided with a relief groove, and the pressing roller 20 is embedded in the relief groove.

[0038] By providing a clearance groove on the mounting housing 14, the pressure roller 20 is given clearance, thus avoiding interference between the mounting housing 14 and the pressure roller 20.

[0039] Implementation process: When it is necessary to open the lid structure, the lifting hydraulic cylinder 12 raises the mounting shell 14 and one end of the lid structure, disengaging the lid structure from the mouth 11 of the torpedo ladle car 10. The electro-hydraulic actuator 15 then retracts the lid structure, moving it away from the mouth 11 of the torpedo ladle car 10, thus facilitating the receiving of molten iron by the torpedo ladle car 10. When it is necessary to close the lid structure, the electro-hydraulic actuator 15 extends the lid structure, and the lifting hydraulic cylinder 12 smoothly lowers the mounting shell 14 and one end of the lid structure, sealing the mouth 11 and preventing heat loss and harmful dust emissions during molten iron transportation.

[0040] During the opening and closing of the lid, the guide component fits tightly against the bottom surface of the lid structure, ensuring smooth operation of the lid structure during retraction and extension. The clamping component dynamically constrains the top surface of the lid structure, preventing the lid structure from tipping over due to center of gravity shift during extension or retraction, thus ensuring the stability of the operation process.
