[0002] The molten iron mixing car is an important tool for transporting molten iron in the modern metallurgical industry. During the transportation of molten iron, the fumes emitted from the molten iron in the mixing car not only cause serious pollution to the atmospheric environment, but also cause the overall temperature of the molten iron to drop, increasing energy consumption and affecting subsequent steelmaking processes. Based on this, major steel mills have added a cover device to the original molten iron mixing car. The installation of the cover device effectively solves the problem of excessive heat dissipation of molten iron through the ladle opening and increased environmental pollution.

[0003] The molten iron transported in the mixed-iron car is an ultra-high temperature liquid. To avoid major safety accidents, the mixed-iron car needs to be taken offline for maintenance after two months of operation. The existing cover device does not need to be moved after installation on the mixed-iron car. During the maintenance period of the mixed-iron car, the cover device remains idle, resulting in low utilization of each device.

Detailed Implementation

[0026] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, Figure 1 A schematic diagram of the installation of the on-board hybrid vehicle cover device that can be installed on both the master and slave ends at the slave and master ends; Figure 2 A structural view of the onboard hybrid vehicle cover device that can be installed on the master and slave ends; Figure 3 This is a cross-sectional view of the connection structure between the fixed arm and the telescopic arm.

[0029] The on-board hybrid steel car cover device that can be installed at both the master and slave ends of this utility model includes a frame 1, a fixed arm 2, a telescopic arm 3, a horizontal telescopic hydraulic cylinder 4, and a pitch hydraulic cylinder 5. The frame 1 is set at the driving end 9 or the driven end 8 of the hybrid steel car. The fixed arm 2 is a hollow tubular component. One end of the fixed arm 2 is an output end, which is open. The other end of the fixed arm 2 is an end end, which is closed by an end cap 21. A support roller is set at the bottom of the fixed arm 2 near the output end. The axis of the support roller 22 is perpendicular to the extension line of the fixed arm 2. The support roller 22 is fixedly set on the frame 1. The fixed arm 2 can rotate around the support roller 22. An ear seat groove 24 is set in the middle of the fixed arm 2. One end of the pitch hydraulic cylinder 5 is connected to the ear seat groove 24, and the other end is connected to the... The frame 1 is connected, and the extension and retraction of the pitch hydraulic cylinder 5 can drive the fixed arm 2 to rotate around the support roller 22, thereby realizing the pitch angle swing of the fixed arm 2. The fixed arm 2 is provided with a first fixed shaft 23 near the end. The telescopic arm 3 is provided with a hollow cavity, which is open at the end of the telescopic arm 3 near the fixed arm 2. One end of the horizontal telescopic hydraulic cylinder 4 is connected to the first fixed shaft 23, and the other end is connected to the hollow cavity of the telescopic arm 3. A heat preservation cover 7 is fixedly provided at the end of the telescopic arm 3 away from the horizontal telescopic hydraulic cylinder 4. One end of the telescopic arm 3 extends into the fixed arm 2 from the output end. The extension and retraction of the horizontal telescopic hydraulic cylinder 4 can drive the telescopic arm 3 to move axially within the fixed arm 2, thereby realizing the linear movement of the heat preservation cover 7.

[0030] This utility model has a simple structure and stable and reliable operation: Compared with other covering devices, the horizontal telescopic hydraulic cylinder 4 is set in the cavity of the fixed arm 2 and the telescopic arm 3, which avoids the possibility of smoke and dust emitted from the molten iron ladle after the iron mixing car is opened and entering the horizontal telescopic hydraulic cylinder 4 under actual working conditions, thus improving the overall reliability of the equipment.

[0031] The frame 1 is bolted to the top of the mixing car. Two bearing seats 11 are symmetrically arranged on the side of the frame 1 near the mouth of the mixing car. The two ends of the support roller 22 are respectively connected to the two bearing seats 11.

[0032] A first connecting seat 12 is provided in the middle of the frame 1, and the first connecting seat 12 is connected to the fixed end of the pitch hydraulic cylinder 5; a second connecting seat 14 is provided at the end of the frame 1 away from the mouth of the mixing car, and a rotating ear 13 is provided on the second connecting seat 14. The rotating ear 13 is set as an L-shaped plate, and a connecting hole is provided at each of the three end positions of the rotating ear 13. The connecting hole located in the middle of the rotating ear 13 is hinged to the second connecting seat 14 by a pin, and the other two connecting holes on the rotating ear 13 are respectively hinged to the output end of the pitch hydraulic cylinder 5 and the ear seat groove by pins.

[0033] The power output from the pitch hydraulic cylinder 5 drives the rotating ear 13 to rotate. The rotation of the rotating ear 13 causes the fixed arm 2 to pitch around the support roller 22 within a certain angle. The frame 1 supports the actuator of the entire covering device. The frame 1 is bolted to the mixing car. When it is necessary to move the covering device from the current mixing car to another mixing car, simply remove the fixing bolts and lift the entire device.

[0034] After all the components of this utility model are installed, they form a movable modular unit that can be quickly moved between different mixed-rail cars. When a mixed-rail car needs to be taken offline for maintenance after a certain period of operation, the covering equipment can be quickly moved from the current mixed-rail car to the next mixed-rail car, avoiding the need to add covering equipment to each mixed-rail car, improving the utilization rate of each covering equipment, and reducing installation and maintenance costs.

[0035] Meanwhile, existing mixed-rail cars are all pulled by locomotives, and the driving end near the locomotive is equipped with a drive mechanism for rotating and tilting the torpedo canisters. The available space is relatively small compared to the driven end. Therefore, existing covering devices are all installed on the driven end of the mixed-rail car. Future mixed-rail cars will mostly develop towards self-drive, requiring the driven end to install the power system and transmission system for propulsion. The available space will become even smaller, eliminating the space for the covering device. Therefore, this invention occupies a more compact installation space than existing covering devices, and requires less space to perform the covering action. The entire device can be installed not only on the driven end of the mixed-rail car but also on the driving end, solving the problem of insufficient space for the covering device after the power system and transmission system for self-drive are installed on the driven end of future mixed-rail cars.

[0036] Example 2

[0037] like Figures 4 to 6 As shown, Figure 4 This is a structural view of the telescopic arm; Figure 5 This is a view of the connection structure between the frame and the fixed arm; Figure 6 This is a cross-sectional view of the telescopic arm.

[0038] A guide device 25 is provided at the position of the fixed arm 2 near the output end. The guide device 25 includes a plurality of first guide pulleys 251. The first guide pulleys 251 are provided at the bottom and on both sides of the telescopic arm 3, and a plurality of first guide pulleys 251 are provided along the extension direction of the fixed arm 2. The first guide pulleys 251 are in contact with the outer wall of the telescopic arm 3 to ensure stable linear movement of the telescopic arm 3 within the fixed arm 2.

[0039] Preferably, the telescopic arm 3 is provided with a second guide pulley 252 at its end inside the fixed arm 2, and the second guide pulley 252 is located at the top of the telescopic arm 3. The first guide pulley 251 and the second guide pulley 252 are equipped with oil-impregnated bearings, and the guiding device 25 can be used without maintenance for its entire lifespan once installed.

[0040] The telescopic arm 3 is inserted into the cavity of the fixed arm 2. The left, right and bottom sides of the telescopic arm 3 abut against the first guide pulley 251 of the fixed arm 2, respectively. The second guide pulley 252 at the tail of the telescopic arm 3 abuts against the upper end face inside the fixed arm 2. The telescopic arm 3 can move along the length direction within the cavity of the fixed arm 2. A second fixed shaft 31 is provided in the cavity of the telescopic arm 3. The second fixed shaft 31 is connected to the output end of the horizontal telescopic hydraulic cylinder 4. The horizontal telescopic hydraulic cylinder is located in the cavity of the fixed arm 2 and the telescopic arm 3.

[0041] In this invention, the guide pulleys on the fixed arm 2 and the telescopic arm 3 are equipped with oil-impregnated bearings, and the oil-impregnated bearings are fitted with sealing rings. During equipment operation, dust in the air and fumes and dust emitted by molten iron are prevented from entering, thereby preventing the service life of the guide device 25 from being reduced. The entire guide device can be maintenance-free for life.

[0042] During the extension and retraction of the telescopic arm 3, the guide pulley converts the sliding friction between the telescopic arm 3 and the fixed arm 2 into rolling friction, reducing the frictional resistance when the telescopic arm 3 extends and retracts, reducing the wear of the telescopic arm 3 and the fixed arm 2, and reducing maintenance costs.

[0043] The telescopic arm 3 and the fixed arm 2 are both provided with fixed shafts for installing the horizontal telescopic hydraulic cylinder 4. The two fixed shafts pass through the telescopic arm 3 and the fixed arm 2 respectively, fixing the horizontal telescopic hydraulic cylinder 4 in the cavity of the telescopic arm 3 and the fixed arm 2. This effectively prevents the smoke and dust emitted after the molten iron ladle is opened from entering the horizontal telescopic hydraulic cylinder 4 and causing equipment failure. When the equipment is actually running, the horizontal telescopic hydraulic cylinder 4 serves as a power source to drive the telescopic arm 3 to extend and retract.

[0044] Example 3

[0045] The telescopic arm 3 is provided with a flange 32 at its end, and the insulation cover 7 is detachably connected to the flange 32 by bolts, which facilitates quick replacement of the insulation cover 7 when it reaches the end of its service life.

[0046] When the molten iron ladle of the mixing car needs to be covered, the telescopic arm 3, driven by the horizontal telescopic hydraulic cylinder 4, extends out from the cavity of the fixed arm 2, so that the heat-insulating cover 7 at the front end of the telescopic arm 3 reaches directly above the mouth of the molten iron ladle of the mixing car; then the pitch hydraulic cylinder 5 retracts, driving the fixed arm 2 and the telescopic arm 3 to rotate around the support roller 22 towards the mouth of the ladle by a certain angle, so that the heat-insulating cover 7 at the front end of the telescopic arm 3 is close to the mouth of the molten iron ladle.

[0047] When the molten iron ladle in the mixing car needs to be opened, the pitching hydraulic cylinder 5 extends, causing the fixed arm 2 and the telescopic arm 3 to rotate around the support roller 22 at a certain angle away from the ladle opening, first causing the insulation cover 7 to move away from the ladle opening; then, the telescopic arm 3 is driven by the horizontal telescopic hydraulic cylinder 4 to retract into the cavity of the fixed arm 2, finally causing the insulation cover 7 to move away from the ladle opening.

[0048] Since the telescopic arm 3 can be completely retracted into the cavity of the fixed arm 2 under the drive of the horizontal telescopic hydraulic cylinder 4, the installation space occupied by the cover device is much smaller than that of the existing cover device. It can be installed on both the active end 9 and the driven end 8 of the mixed-rail vehicle, avoiding the situation that there is no space to install the cover device after the driven end 8 of the mixed-rail vehicle is installed with the power system and transmission system for its own drive.

[0049] In actual operation, after the insulation cover 7 is installed above the opening of the molten iron ladle, it is constantly in an ultra-high temperature environment. As the equipment operates for longer periods, the insulation cover 7 inevitably experiences thermal degradation, resulting in a decrease in insulation performance. In this case, simply remove the insulation cover 7 from the flange 32 at the end of the telescopic arm 3 and replace it with a new insulation cover 7.

[0050] Example 4

[0051] like Figure 7 As shown, Figure 7 This is an indicator diagram of the active and driven ends of the mixed-rail car; the frame 1, the fixed arm 2, the telescopic arm 3, the horizontal telescopic hydraulic cylinder 4, the pitch hydraulic cylinder 5, and the heat insulation cover 7 installed at the end of the telescopic arm 3 are connected and integrated into a whole movable module, and the cover device can be quickly replaced between different mixed-rail cars.

[0052] Existing mixed-steel cars require maintenance after a certain period of operation, at which time the cover device installed on the car will be idle. Since all components of the cover device are integrated into a single movable module after installation and connection, the bolts connecting the frame to the mixed-steel car can be removed, and the entire device can be moved to another mixed-steel car. This avoids the need to install a cover device on every mixed-steel car, greatly improving the utilization rate of each piece of equipment and reducing the installation and maintenance costs.

[0053] Example 5

[0054] like Figure 8 As shown, Figure 8 The image shows the installation position of the hydraulic station. The on-board mixed-rail car cover device that can be installed at the master and slave ends also includes a hydraulic station 6. The hydraulic station 6 is installed in the housing of the slave end 8 in the mixed-rail car. The horizontal telescopic hydraulic cylinder 4 and the pitch hydraulic cylinder 5 are connected to the hydraulic station 6 via oil pipes for control.

[0055] It should be noted that when the covering device needs to be moved between mixed-rail cars, the hydraulic station 6 only needs to be moved from the current mixed-rail car to the other mixed-rail car, and the hydraulic station 6 can be connected to the hydraulic cylinder of the covering device using an oil pipe; in addition, the driving method of the covering device is not limited to hydraulic drive. In other embodiments, it can also be a gear drive, ball screw drive, pneumatic drive or other transmission methods.

[0056] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
