Description

Technical Field

[0001] The invention relates to the technical field of automatic dumping large-tonnage molten iron transfer vehicle equipment, and specifically to an automatic dumping large-tonnage molten iron transfer vehicle and a use method thereof. Background Art

[0002] The automatic dumping large-tonnage molten iron transfer car is a special equipment used in the cast iron production process. Cast iron production usually requires the transfer of molten iron from one place to another under high temperature conditions, and this transfer usually requires the handling of large tonnage of molten iron. The automatic dumping large-tonnage molten iron transfer car is designed to complete this task safely and efficiently.

[0003] The molten iron transfer vehicle is a vehicle for transporting molten iron. When dumping molten iron, the existing molten iron transfer vehicle will produce a gap between the inclined rotating shaft on the molten iron ladle and the supporting wall due to long-term wear, which makes the molten iron ladle shake when dumping, making the dumping of molten iron unstable and causing molten iron to splash.

[0012] Furthermore, the locking and limiting mechanism also includes a sliding groove 2 opened on the support arm, a sliding block 1 is slidably connected inside the sliding groove 2, one end of the sliding block 1 is fixedly connected to a vertical rod, a groove is opened on the vertical rod, a movable column is slidably connected to the vertical rod, one end of the sliding block 1 is fixedly connected to a push plate 1, and an end of the push plate 1 away from the sliding block 1 is fixedly connected to a plurality of locking columns.

[0014] The method of using the automatic dumping large-tonnage molten iron transfer vehicle includes the following steps:

[0015] S1: An installation device, wherein the installation base of the installation device is fixedly connected to the lifting platform of the forklift;

[0016] S2: Carrying molten iron, aligning the tipping axis of the side wall of the ladle with the groove on the support arm, thereby realizing the transfer of the ladle;

[0017] S3: lifting the molten iron cover, by using the lifting hydraulic cylinder in the lifting mechanism to pull the molten iron cover at one end of the chain;

[0018] S4: dumping the molten iron, by utilizing the lifting and lowering of the dumping hydraulic cylinder to drive the pull rope on the lifting sleeve to pull the hook, thereby realizing the tilting of the molten iron ladle.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a locking limit mechanism. When the lifting sleeve moves upward, the lifting sleeve drives the slide groove bar to move upward. When the slide groove bar moves upward, the moving column and the tilting rod are squeezed. At this time, the moving column drives the sliding block to move along the groove toward one end close to the tipping axis. In addition, the moving column will also drive the vertical rod to move toward one end close to the tipping axis. The movement of the vertical rod drives the sliding block 1 to move along the slide groove 2 toward one end close to the tipping axis. The movement of the sliding block 1 drives the locking column on the push plate 1 to move toward one end close to the tipping axis. At this time, the locking column will be locked inside the groove on the support arm. This arrangement is beneficial to the fact that the tipping axis on the ladle will not be separated from the support arm when the molten iron is dumped, thereby reducing the risk of the molten iron ladle being separated and improving the safety performance of the device.

[0021] (2) The present invention provides a lifting mechanism for the molten iron cover. After the molten iron ladle is loaded, the lifting hydraulic cylinder is controlled to rise. The lifting hydraulic cylinder drives the chain to rise. At this time, the molten iron cover at the other end of the chain descends under the action of its own gravity. The molten iron cover pulls the fixed roller on the moving rod at one end of the chain to slide along the slide groove. When the molten iron cover descends to the top of the molten iron ladle and fits with the upper end of the molten iron ladle, the lifting hydraulic cylinder stops rising. A plurality of fixed rollers are arranged inside the slide groove so that the moving rod can slide stably in a directional manner. Limiting the moving rod is conducive to the stable descent of the molten iron cover at one end of the chain, avoiding the shaking and dislocation caused by the rapid fall of the molten iron cover. Three chains are arranged above the molten iron cover. The fixed points between the chains and the molten iron cover form a stable triangular structure. Such an arrangement is conducive to reducing the shaking of the molten iron cover as much as possible during the descent.

[0022] (3) The present invention provides a dumping mechanism. When it is necessary to pour out the molten iron in the ladle, the molten iron cover lifting mechanism is started to descend to drive the molten iron cover to rise, and the dumping hydraulic cylinder is started to rise. The dumping hydraulic cylinder rises and drives the lifting sleeve to slide upward along the slide groove rod. The slide groove rod slides upward to drive the lifting rod to move upward. The lifting rod moves upward to drive the pull rope on the lifting wheel to move upward. The pull rope moves upward to drive the pull ring to pull the hook upward. At this time, pulling the hook will cause the molten iron ladle to tilt outward around the dumping axis, so that the molten iron in the ladle is poured out. A limit roller is provided on the lifting sleeve. The limit roller slides on the slide groove rod to make the lifting sleeve rise stably, thereby improving the stability of the dumping of the device. By providing a fixed roller 2 on the lifting sleeve, the fixed roller 2 contacts with the surface of the slide groove rod. When the lifting sleeve rises, the fixed roller 2 rolls, and rolling friction occurs between the fixed roller 2 and the slide groove rod. Since the rolling friction is much smaller than the sliding friction, the lifting sleeve slides more smoothly on the slide groove rod.

[0023] (4) The present invention provides a friction mechanism. When the vertical rod moves, the sliding block 1 moves along the slide groove 2 toward one end of the tipping shaft. The sliding block 1 drives the push plate 1 along the slide groove 2 to squeeze the spring. At this time, the elastic force of the squeezing spring on the push plate 2 gradually increases, and the squeezing force of the push plate 2 on the locking block also gradually increases. The squeezing force between the locking block and the tipping shaft increases, and the friction force increases, so that the tipping shaft is not easy to shake in the groove on the support arm, thereby ensuring that the molten iron ladle remains stable when tipping, which is beneficial to the operator's control of the tilt angle of the molten iron ladle.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of fixed rollers 1 305 are arranged inside the slide groove 1 304, so that the moving rod 306 can slide in a directional and stable manner. Limiting the moving rod 306 is conducive to the stable descent of the molten iron cover 307 at one end of the chain 302, and avoids the molten iron cover 307 from shaking and misalignment due to rapid falling. Three chains 302 are arranged above the molten iron cover 307, and the fixed points between the chains 302 and the molten iron cover 307 form a stable triangular structure. Such an arrangement is conducive to reducing the shaking of the molten iron cover 307 as much as possible during the descent.

[0042] A tipping mechanism 4 is arranged directly above the support arm 14, and the tipping mechanism 4 includes a slide rod 401 fixedly connected directly above the support arm 14, a lifting sleeve 402 is sleeved on the slide rod 401, and a side wall of the lifting sleeve 402 is rotatably connected to a limiting roller 403, and the limiting roller 403 is slidably connected to the slide rod 401.

At this time, pulling the hook 204 will cause the molten iron ladle 203 to tilt outward around the tipping axis 201, so that the molten iron inside the molten iron ladle 203 is poured out, and a limiting roller 403 is arranged on the lifting sleeve 402, and the limiting roller 403 slides on the slide rod 401 to make the lifting sleeve 402 rise stably, thereby improving the stability of the dumping of the device, and by arranging a fixed roller 404 on the lifting sleeve 402, the fixed roller 404 is in contact with the surface of the slide rod 401, when the lifting sleeve 402 rises, the fixed roller 404 rolls, and rolling friction occurs between the fixed roller 404 and the slide rod 401. Since the rolling friction is much smaller than the sliding friction, the lifting sleeve 402 slides on the slide rod 401 more smoothly.

[0044] Embodiment 2 is different from Embodiment 1 in that: Figure 1-Figure 10 As shown, the side wall of the slide rod 401 is provided with a locking and limiting mechanism 5, which includes a slide bar 501 fixedly connected to the side of the lifting sleeve 402 away from the limiting roller 403, a groove 502 is provided on the side of the slide bar 501 away from the lifting sleeve 402, a slider 503 is slidably connected inside the groove 502, a moving column 504 is fixedly connected to the side of the slider 503 away from the groove 502, a plurality of tilting rods 505 are fixedly connected to the top of the fixed rod 16, an inclined groove is provided on the tilting rod 505, and the moving column 504 is slidably connected to the tilting rod 505.

[0045] The locking and limiting mechanism 5 also includes a slide groove 2 507 provided on the support arm 14, a sliding block 1 508 is slidably connected inside the slide groove 2 507, one end of the sliding block 1 508 is fixedly connected to the vertical rod 506, a groove is provided on the vertical rod 506, the moving column 504 is slidably connected to the vertical rod 506, one end of the sliding block 1 508 is fixedly connected to a push plate 1 509, and one end of the push plate 1 509 away from the sliding block 1 508 is fixedly connected to a plurality of locking columns 510. The function of this component is to set the locking and limiting mechanism 5, when the lifting sleeve 402 moves upward, the lifting sleeve 402 drives the slide groove bar 501 to move upward, and when the slide groove bar 501 moves upward, the moving column 504 is squeezed with the tilting rod 505. At this time, the moving column 50 The sliding block 503 is driven to move along the groove 502 toward one end of the tipping axis 201. In addition, the moving column 504 also drives the vertical rod 506 to move toward one end of the tipping axis 201. The movement of the vertical rod 506 drives the sliding block 1 508 to move along the sliding groove 2 507 toward one end of the tipping axis 201. The movement of the sliding block 1 508 drives the locking column 510 on the pushing plate 1 509 to move toward one end of the tipping axis 201. At this time, the locking column 510 locks the locking column 510 in the groove on the support arm 14. This arrangement is conducive to the tipping axis 201 on the ladle 203 not being separated from the support arm 14 when the molten iron is being dumped, thereby reducing the risk of the molten iron ladle 203 being separated and improving the safety performance of the device.

[0046] The support arm 14 is provided with a friction mechanism 6 inside, and the friction mechanism 6 includes an extrusion spring 601 fixedly connected to the side of the push plate 1 509 away from the sliding block 1 508, and the end of the extrusion spring 601 away from the push plate 1 509 is fixedly connected to the push plate 2 602, and the push plate 2 602 is slidably connected to the support arm 14 through the slide groove 2 507, and the support arm 14 is provided with a slide groove 3 603 inside, and the slide groove 3 603 is slidably connected with a locking block 604, and the end of the locking block 604 away from the tipping shaft 201 is fixedly connected to the limit ring 605, and the locking block 604 is sleeved with a pressure spring 606.

At this time, the elastic force of the squeezing spring 601 on the pushing plate 2 602 gradually increases, and the squeezing force of the pushing plate 2 602 on the locking block 604 also gradually increases. The squeezing force between the locking block 604 and the tipping axis 201 increases, and the friction force increases, so that the tipping axis 201 is not easy to shake in the groove on the support arm 14, thereby ensuring that the molten iron ladle 203 remains stable during tipping, which is beneficial for the operator to control the tilt angle of the molten iron ladle 203.

[0047] The method of using the automatic dumping large-tonnage molten iron transfer vehicle includes the following steps:

[0048] S1: Installing the device, fixing the mounting base 1 in the device to the lifting platform of the forklift;

[0049] S2: Carrying molten iron, aligning the tipping axis 201 of the side wall of the ladle 203 with the groove on the support arm 14, thereby realizing the transfer of the ladle;

[0050] S3: lifting the molten iron cover 307, by using the lifting hydraulic cylinder 301 in the lifting mechanism 3 to pull the molten iron cover 307 at one end of the chain 302;

[0051] S4: pouring the molten iron, by utilizing the lifting and lowering of the dumping hydraulic cylinder 15 to drive the pull rope 407 on the lifting sleeve 402 to pull the hook 204, so as to achieve the tilting of the molten iron ladle 203.

[0052] A specific application of this embodiment is:

[0053] When using the device, the mounting base 1 in the device is fixedly connected to the lifting platform of a forklift, and by setting up the transport mechanism 2, firstly, the tipping shaft 201 of the side wall of the iron ladle 203 filled with molten iron is loaded into the groove at one end of the support arm 14, and the limit block 202 is stuck in the side wall of the support arm 14 at this time, and this arrangement is conducive to keeping the iron ladle 203 stable during transportation; by setting up the iron ladle cover lifting mechanism 3, after the iron ladle 203 is loaded, the lifting hydraulic cylinder 301 is controlled to rise, and the lifting hydraulic cylinder 301 rises to drive the chain 302 to rise, and at this time, the iron ladle 307 at the other end of the chain 302 descends under the action of its own gravity, and the iron ladle 307 pulls the chain The fixed roller 305 on the moving rod 306 at one end of the chain 302 slides along the slide groove 304. When the molten iron cover 307 drops to the top of the molten iron ladle 203 and fits with the upper end of the molten iron ladle 203, the lifting hydraulic cylinder 301 stops rising. A plurality of fixed rollers 305 are arranged inside the slide groove 304, so that the moving rod 306 can slide in a directional and stable manner. Limiting the moving rod 306 is conducive to the stable descent of the molten iron cover 307 at one end of the chain 302, and avoids the shaking and misalignment caused by the rapid fall of the molten iron cover 307. Three chains 302 are arranged above the molten iron cover 307, and the fixed points between the chains 302 and the molten iron cover 307 form a stable triangular structure. , such a setting is conducive to reducing the shaking of the molten iron cover 307 as much as possible during the descent process; by setting the dumping mechanism 4, when the molten iron inside the molten iron ladle 203 needs to be poured out, the molten iron cover 307 is driven to rise by starting the molten iron cover lifting mechanism 3 to descend, and the dumping hydraulic cylinder 15 is started to rise. The dumping hydraulic cylinder 15 rises and drives the lifting sleeve 402 to slide upward along the slide rod 401. The slide rod 401 slides upward and drives the lifting rod 405 to move upward. The lifting rod 405 moves upward and drives the pull rope 407 on the lifting wheel 406 to move upward. The pull rope 407 moves upward and drives the pulling ring 408 to pull the hook 204 upward. At this time, pulling the hook 204 will make the molten iron ladle 20 3 tilts outward around the tipping axis 201, so that the molten iron in the ladle 203 is poured out, and a limiting roller 403 is set on the lifting sleeve 402, and the limiting roller 403 slides on the slide rod 401 to make the lifting sleeve 402 rise stably, thereby improving the stability of the device when tipping, and by setting a fixed roller 2 404 on the lifting sleeve 402, the fixed roller 2 404 is in contact with the surface of the slide rod 401, when the lifting sleeve 402 rises, the fixed roller 2 404 rolls, and rolling friction occurs between the fixed roller 2 404 and the slide rod 401. Since the rolling friction is much smaller than the sliding friction, the lifting sleeve 402 slides on the slide rod 401 more smoothly;

[0054] By setting the locking limit mechanism 5, when the lifting sleeve 402 moves upward, the lifting sleeve 402 drives the slide groove bar 501 to move upward. When the slide groove bar 501 moves upward, the moving column 504 is squeezed with the tilting rod 505. At this time, the moving column 504 drives the sliding block 503 to move along the groove 502 toward one end close to the tipping axis 201. In addition, the moving column 504 will also drive the vertical rod 506 to move toward one end close to the tipping axis 201. The vertical rod 506 moves and drives the sliding block 1 508 to move along the slide groove 2 507 toward one end close to the tipping axis 201. The sliding block 1 508 moves and drives the locking column 510 on the pushing plate 1 509 to move toward one end close to the tipping axis 201. At this time, the locking column 510 locks 210 inside the groove on the support arm 14. This arrangement is conducive to the ladle 203 on the ladle 203 when dumping molten iron. The tipping shaft 201 will not be separated from the support arm 14, which reduces the risk of the molten iron ladle 203 being separated and improves the safety performance of the device; by setting the friction mechanism 6, when the vertical rod 506 moves, it drives the sliding block 1 508 to move along the slide groove 2 507 toward one end of the tipping shaft 201, the sliding block 1 508 drives the push plate 1 509 to squeeze the spring 601 along the slide groove 2 507. At this time, the push plate 2 602 is gradually increased by the elastic force of the squeezing spring 601, and the squeezing force of the push plate 2 602 on the locking block 604 also gradually increases. The squeezing force between the locking block 604 and the tipping shaft 201 increases, and the friction force increases, so that the tipping shaft 201 is not easy to shake in the groove on the support arm 14, thereby ensuring that the molten iron ladle 203 remains stable when tipping, which is beneficial to the operator's control of the tilt angle of the molten iron ladle 203.
