[0001] The invention relates to the technical field of molten iron transportation, and in particular to a molten iron transportation device with high stability. Background Art

[0002] It is usually composed of a molten iron ladle and a tractor. The molten iron ladle is a container for loading molten iron, which is required to have properties such as high temperature resistance and corrosion resistance. The tractor is used to tow the molten iron ladle, which is required to have sufficient traction and stability. The molten iron transfer equipment needs to improve transportation safety and reduce risks and accidents during transportation, so the molten iron ladle needs to be effectively sealed. The existing molten iron transfer equipment cannot adjust the molten iron ladle sealing device according to the size of the molten iron ladle, has poor applicability, and poor sealing effect.

[0003] The patent with patent number CN217452112U discloses a molten iron transfer device for castings. The setting of the protective cap of the patent can realize the limiting effect on the molten iron ladle, improve the stability of the molten iron ladle during transportation, and avoid splashing of molten iron, thereby improving the safety of the transportation process; the mutual cooperation between the molten iron ladle and the moving component and the rotating component realizes the flexibility of the molten iron ladle to pour the molten iron, facilitates the injection and pouring of molten iron, improves the production efficiency, has strong overall practicality, a wide range of applications, and is suitable for the transportation of various materials. Although the patent solves the above problems, there is still the problem that the sealing device of the molten iron tank cannot be adjusted according to the size of the molten iron tank, the applicability is poor, and the sealing effect is not good. Therefore, a molten iron transfer equipment with high stability is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a molten iron transfer device with high stability in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a molten iron transfer equipment with high stability, including a tractor, a wheel is rotatably connected to the bottom of the tractor, a molten iron tank is fixedly connected to the upper surface of the tractor, a linear motor is fixedly connected to the upper surface of the tractor, a gantry is slidably connected to the upper surface of the linear motor, a support plate is fixedly connected to the bottom of the inner surface of the gantry, a hydraulic cylinder is fixedly connected to the upper surface of the support plate, a sliding seat is slidably connected to the inner surface of the gantry, a sealing half cover is fixedly connected to the side of the sliding seat close to the molten iron tank, a fixed block is fixedly connected to the upper surface of the sealing half cover on the left side, a semicircular head pin is slidably connected to the right inner surface of the fixed block, and the semicircular head pin is slidably connected to the inner surface of the fixed block. The circumferential surface of the pin is sleeved with a movable sleeve lock, the upper surface of the sealing half cover on the right side is fixedly connected with a positioning cylinder, the inner wall of the positioning cylinder is fixedly connected with a return spring, and the end of the return spring away from the inner wall of the positioning cylinder is fixedly connected with a locking pin, a clamping device for preventing the molten iron tank from tipping over is arranged above the tractor, and supporting devices for preventing the tractor from shaking when inverting the molten iron are arranged on the front and rear sides of the tractor, the top surface of the hydraulic cylinder and the lower surface of the sliding seat are in contact with each other, the locking pin and the inner wall of the positioning cylinder are slidably connected, the molten iron tank is fixed to the tractor, and then the molten iron is poured into the molten iron tank, the linear motor is started, the linear motor drives the gantry to approach the molten iron tank, and the gantry then drives the sliding seat and the sealing half cover to the molten iron tank When the sealing half covers on both sides of the molten iron tank fit together, the molten iron tank can be sealed. The hydraulic cylinder is started, and the hydraulic cylinder drives the sliding seat and the sealing half covers to rise and fall, so as to adjust the sealing half covers to a suitable position according to the height of the molten iron tank. After the sealing half covers on the left and right sides of the molten iron tank fit together, the positioning cylinder on the right side of the fixed block on the left side is driven to contact each other, and the fixed block drives the semicircular head latch and the movable sleeve lock to insert into the positioning cylinder. When the semicircular arc surface on the right side of the semicircular head latch contacts the inclined surface on the left side of the locking latch, the locking latch is pushed to the end close to the reset spring through the guide between the arc surface and the inclined surface, thereby contracting the reset spring, and then the locking latch is ejected by the elastic reset action of the reset spring and inserted between the semicircular head latch and the movable sleeve lock, from The semicircular head pin is fixed in the positioning cylinder. When the sealing half cover needs to be opened, the semicircular head pin is pushed to the right for a distance. At this time, the inclined surface on the right side of the movable lock contacts the inclined surface on the left side of the locking pin, and the locking pin is pushed out to the surroundings through the guidance of the inclined surface, so that the movable lock moves to the right side of the locking pin. At this time, the linear motor is started, and the linear motor drives the sealing half cover away from the molten iron ladle. The fixed block and the semicircular head pin are pulled away from the positioning cylinder by the pulling force of the sealing half cover. At this time, the inclined surface on the left side of the movable lock contacts the inclined surface on the right side of the locking pin. Because the semicircular head pin moves to the left, the movable lock pushes the locking pin to contract again, and makes the semicircular head pin break away from the limit of the locking pin, thereby completely separating the fixed block and the positioning cylinder.

[0006] The locking plate is secured to the bottom of the support rail and is adapted to engage with the locking plate to engage with the locking plate, the locking plate being secured to the bottom of the support rail and to the locking plate. The upper and lower connecting plates are respectively driven by the lower supporting arc plates and the upper supporting arc plates to move toward the molten iron tank. When the lower supporting arc plates and the upper supporting arc plates are in contact with the outer surface of the molten iron tank, the lower supporting arc plates and the upper supporting arc plates on both sides clamp the molten iron tank, and the lower supporting arc plates and the upper supporting arc plates respectively drive the movable arc plates on both sides of the molten iron tank to move toward the molten iron tank. The movable arc plates stop after contacting the molten iron tank. During transportation, the molten iron inside the molten iron tank shakes and the shaking force is transmitted to the movable arc plates through the molten iron tank to the movable arc plates. After being affected by the force, the movable arc plates on both sides respectively move toward the lower supporting arc plates and the upper supporting arc plates, thereby driving the sliding rod and the limiting ring to move away from the molten iron tank. When the limiting ring moves away from the molten iron tank, the adjusting spring is pulled, and then the elastic reset effect of the adjusting spring pulls the limiting ring toward the molten iron tank again, thereby offsetting the shaking force. In this process, the sliding rod slides back and forth on the inner surfaces of the lower supporting arc plates and the upper supporting arc plates, and the shaking force is converted into friction and eliminated.

[0007] The L-shaped support rod is fixedly connected to the front and rear sides of the tractor, and the L-shaped support rod is hinged on the circumferential surface of the limit shaft. The reinforcing diagonal rod is fixedly connected to the side of the L-shaped support rod away from the tractor, and the adjusting support screw is threadedly connected to the bottom of the L-shaped support rod. The support device also includes a transmission rod, a transmission slot block, an L-shaped fixing piece, and a fixing screw. The transmission rod is fixedly connected to the side of the lower connecting plate away from the lower supporting arc plate, the transmission slot block is fixedly connected to one end of the transmission rod away from the lower connecting plate, the L-shaped fixing piece is fixedly connected to the front and rear sides of the tractor, the fixing screw is threadedly connected to the inner surface of the L-shaped fixing piece, and a positioning hole is opened on the side of the bottom of the L-shaped support rod close to the tractor, the L-shaped support rod and the front and rear sides of the tractor are in contact with each other. When the vehicle is parked on the rails and molten iron is poured into the molten iron tank, the L-shaped support rod is rotated along the limit axis to make the L-shaped support rod perpendicular to the ground, and then the adjusting support screw is rotated, and the adjusting support screw moves downward through the thread spiral and contacts the ground, so that the tractor can contact the ground through the L-shaped support rod and the adjusting support screw, and the reinforcing diagonal rod can reinforce the L-shaped support rod and form a triangular stable area with the L-shaped support rod. When the molten iron is loaded, the gantry drives the lower connecting plate to approach the molten iron tank, and the lower connecting plate drives the transmission rod and the transmission slot block to approach the molten iron tank. When the inner surface of the transmission slot block contacts the top of the L-shaped support rod, it can drive the L-shaped support rod to rotate, so that the L-shaped fixing piece is finally parallel to the ground. After the L-shaped support rod is parallel to the ground, it is stuck in the L-shaped fixing piece. At this time, the fixing screw can be rotated to insert the fixing screw into the positioning hole opened on the L-shaped support rod.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects:

[0009] 1. This molten iron transfer equipment has high stability. The sealing half covers on both sides of the molten iron tank can seal the molten iron tank after being fitted together to prevent the molten iron from splashing during transportation. The sliding seat and the sealing half cover are raised and lowered. The sealing half cover is adjusted to a suitable position according to the height of the molten iron tank, so that the sealing half cover can seal molten iron tanks of different heights, thereby improving the applicability of the device. The semi-circular head pin is fixed in the positioning cylinder, thereby better fixing the sealing half cover and improving the stability during sealing. The fixing block and the positioning cylinder are completely separated, and then the sealing half cover is quickly opened to load and unload the molten iron.

[0010] 2. This highly stable molten iron transfer equipment has a lower supporting arc plate and an upper supporting arc plate that clamp the molten iron tank when they are in contact with the outer surface of the molten iron tank, making the molten iron tank more stable during transportation and will not be affected by the shaking of the molten iron and thus tip over and fall away from the tractor, making transportation safer. The slide bar slides back and forth on the inner surface of the lower supporting arc plate and the upper supporting arc plate, converting the shaking force into friction and eliminating it, thereby greatly reducing the shaking of the molten iron in the molten iron tank during transportation and further improving transportation safety.

[0011] 3. The molten iron transfer equipment with high stability has the tractor in contact with the ground through the L-shaped support rod and the adjusting support screw, which improves the supporting force. The strengthening of the oblique rod and the L-shaped support rod forms a triangular stable area to further improve the supporting force, making the tractor more stable when stopped, preventing the tractor from deviating on the rails and causing the molten iron tank to deviate, thereby preventing the molten iron from splashing around and causing harm and waste. The transmission slot block drives the L-shaped support rod to rotate, so that the L-shaped fixing part is parallel to the ground, so that the L-shaped support rod can be quickly retracted without affecting the transportation, which improves the convenience of use. After the L-shaped support rod is parallel to the ground, it is stuck in the L-shaped fixing part. At this time, the fixing screw can be rotated to insert the fixing screw into the positioning hole opened on the L-shaped support rod to improve the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

A locking pin 411 is fixedly connected to one end. The sealing half covers 45 on both sides of the molten iron tank 3 can seal the molten iron tank 3 after being fitted together to prevent the molten iron from splashing during transportation. The sliding seat 44 and the sealing half cover 45 are raised and lowered, and the sealing half cover 45 is adjusted to a suitable position according to the height of the molten iron tank 3, so that the sealing half cover 45 can seal the molten iron tanks 3 at different heights, thereby improving the applicability of the device. A clamping device 5 for preventing the molten iron tank 3 from tipping over is arranged above the tractor 1, and a supporting device 6 for preventing the tractor 1 from shaking when inverting the molten iron is arranged on the front and rear sides of the tractor 1. The top surface of the hydraulic cylinder 43 and the lower surface of the sliding seat 44 are in contact with each other, the locking pin 411 and the inner wall of the positioning cylinder 49 are slidably connected, and the semicircular head pin 47 is fixed in the positioning cylinder 49, thereby better fixing the sealing half cover 45 and improving the stability during sealing. The fixing block 46 and the positioning cylinder 49 are completely separated, and then the sealing half cover 45 is quickly opened to open and then load and unload the molten iron.

[0023] Working principle: Fix the molten iron tank 3 to the tractor 1, then pour the molten iron into the molten iron tank 3, start the linear motor 4, the linear motor 4 drives the gantry 41 to approach the molten iron tank 3, the gantry 41 then drives the sliding seat 44 and the sealing half cover 45 to approach the molten iron tank 3, when the sealing half covers 45 on both sides of the molten iron tank 3 fit together, the molten iron tank 3 can be sealed to prevent the molten iron from splashing during transportation, start the hydraulic cylinder 43, the hydraulic cylinder 43 drives the sliding seat 44 and the sealing half cover 45 to rise and fall, so as to adjust the sealing half cover 45 to a suitable position according to the height of the molten iron tank 3, so as to make the sealing The half cover 45 can seal the molten iron tank 3 at different heights, thereby improving the applicability of the device. After the sealing half covers 45 on the left and right sides of the molten iron tank 3 are fitted together, the positioning cylinder 49 on the right side of the fixed block 46 on the left side is driven to contact each other. The fixed block 46 drives the semicircular head latch 47 and the movable sleeve lock 48 to insert into the positioning cylinder 49. When the right semicircular arc surface of the semicircular head latch 47 contacts the left inclined surface of the locking latch 411, the locking latch 411 is pushed toward one end of the reset spring 410 through the guide between the arc surface and the inclined surface, thereby contracting the reset spring 410, and then the locking latch 41 The semicircular head latch 47 is popped out and inserted between the semicircular head latch 47 and the movable sleeve lock 48 by the elastic restoring effect of the restoring spring 410, so that the semicircular head latch 47 is fixed in the positioning cylinder 49, thereby better fixing the sealing half cover 45 and improving the stability during sealing. When it is necessary to open the sealing half cover 45, the semicircular head latch 47 is pushed to the right for a distance. At this time, the inclined surface on the right side of the movable sleeve lock 48 contacts the inclined surface on the left side of the locking latch 411, and the locking latch 411 is pushed out to the surroundings by the guidance of the inclined surface, so that the movable sleeve lock 48 moves to the right side of the locking latch 411.

The fixed block 46 and the semicircular head pin 47 are pulled by the sealing half cover 45 and thus move away from the positioning tube 49. At this time, the left inclined surface of the movable lock sleeve 48 contacts the right inclined surface of the locking pin 411. Because the semicircular head pin 47 moves to the left, the movable lock sleeve 48 pushes the locking pin 411 to contract again, and makes the semicircular head pin 47 disengage from the limit of the locking pin 411, so that the fixed block 46 and the positioning tube 49 are completely separated, and then the sealing half cover 45 is quickly opened to open and then the molten iron is loaded and unloaded.

The lower connecting plate 51 is fixedly connected to one side of the gantry 41 close to the molten iron tank 3, the lower supporting arc plate 52 is fixedly connected to one end of the lower connecting plate 51 close to the molten iron tank 3, the upper connecting plate 53 is fixedly connected to one side of the gantry 41 close to the molten iron tank 3, and the upper supporting arc plate 54 is fixedly connected to one end of the upper connecting plate 53 close to the molten iron tank 3. When the lower supporting arc plate 52 and the upper supporting arc plate 54 are in contact with the outer surface of the molten iron tank 3, the lower supporting arc plates 52 and the upper supporting arc plates 54 on both sides clamp the molten iron tank 3, so that the molten iron tank 3 is more stable during transportation, and will not be affected by the shaking of the molten iron and thus fall off the tractor 1, making transportation safer. The clamping device 5 It also includes a movable arc plate 55, a slide bar 56, a limit ring 57, and an adjusting spring 58. The sliding ring of the slide bar 56 is connected to the inner surface of the lower supporting arc plate 52, and the limit ring 57 is fixedly connected to the end of the slide bar 56 circumferential surface away from the molten iron tank 3. The movable arc plate 55 is fixedly connected to the end of the slide bar 56 close to the molten iron tank 3, and the adjusting spring 58 is fixedly connected to the side of the limit ring 57 close to the molten iron tank 3. The slide bar 56 is slidably connected to the inner surface of the upper supporting arc plate 54, and the end of the adjusting spring 58 close to the molten iron tank 3 and the upper connecting plate 53 are fixedly connected to the side of the upper supporting arc plate 54 away from the molten iron tank 3. The slide bar 56 slides back and forth on the inner surfaces of the lower supporting arc plate 52 and the upper supporting arc plate 54, converting the shaking force into friction and eliminating it, thereby greatly reducing the shaking of the molten iron in the molten iron tank 3 during transportation, and further improving transportation safety.

[0025] Working principle: Gantry 41 drives lower connecting plate 51 and upper connecting plate 53 to approach molten iron tank 3, and lower connecting plate 51 and upper connecting plate 53 respectively drive lower supporting arc plate 52 and upper supporting arc plate 54 to approach molten iron tank 3, and when lower supporting arc plate 52 and upper supporting arc plate 54 contact with outer surface of molten iron tank 3, lower supporting arc plate 52 and upper supporting arc plate 54 on both sides clamp molten iron tank 3, so that molten iron tank 3 is more stable during transportation, and will not be affected by shaking of molten iron and thus tip over and detach from tractor 1, so that transportation is safer, and lower supporting arc plate 52 and upper supporting arc plate 54 respectively drive movable arc plates 55 on both sides of molten iron tank 3 to approach molten iron tank 3, and movable arc plates 55 stop after contacting molten iron tank 3, so that molten iron tank 3 is in transportation. 3 After the molten iron inside shakes, the shaking force is transmitted to the movable arc plate 55 through the molten iron tank 3. After being affected by the force, the movable arc plates 55 on both sides move closer to the lower supporting arc plate 52 and the upper supporting arc plate 54 respectively, thereby driving the sliding rod 56 and the limiting ring 57 away from the molten iron tank 3. When the limiting ring 57 moves away from the molten iron tank 3, it pulls the adjusting spring 58. Then, the elastic reset effect of the adjusting spring 58 pulls the limiting ring 57 towards the molten iron tank 3 again, thereby offsetting the shaking force. During this process, the sliding rod 56 slides back and forth on the inner surfaces of the lower supporting arc plate 52 and the upper supporting arc plate 54, converting the shaking force into friction and eliminating it, thereby greatly reducing the shaking of the molten iron in the molten iron tank 3 during transportation, further improving transportation safety.

The tractor 1 contacts the ground through the L-shaped support rod 62 and the adjusting support screw 64, thereby improving the supporting force. The reinforcing inclined rod 63 and the L-shaped support rod 62 form a triangular stable area to further improve the supporting force, making the tractor 1 more stable when it stops, preventing the tractor 1 from deviating on the rails and causing the molten iron tank 3 to deviate, thereby splashing the molten iron around and causing harm and waste. The support device 6 also includes a transmission rod 65, a transmission slot block 66, and an L The L-shaped fixing piece 67 and the fixing screw 68 are fixedly connected to the side of the lower connecting plate 51 away from the lower supporting arc plate 52, and the transmission slot block 66 is fixedly connected to the end of the transmission rod 65 away from the lower connecting plate 51.

The strengthening diagonal rod 63 can reinforce the L-shaped support rod 62 and form a triangular stable area with the L-shaped support rod 62 to further improve the supporting force, making the tractor 1 more stable when it stops, preventing the tractor 1 from deviating on the rail and causing the molten iron tank 3 to deviate so that the molten iron moves to the four sides. The splashing around causes harm and waste. After the molten iron is loaded, the gantry 41 drives the lower connecting plate 51 to approach the molten iron tank 3, and the lower connecting plate 51 drives the transmission rod 65 and the transmission slot block 66 to approach the molten iron tank 3. When the inner surface of the transmission slot block 66 contacts the top of the L-shaped support rod 62, it can drive the L-shaped support rod 62 to rotate, so that the L-shaped fixing piece 67 is finally parallel to the ground, so that the L-shaped support rod 62 can be quickly retracted without affecting the transportation, thereby improving the convenience of use.
