Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a casting ladle with safe operation. Background Art

[0002] The ladle is a special container for transporting molten steel. Its structural design includes the outer shell, insulation layer, pouring gate, supporting structure and control facilities. The design and manufacture of the ladle need to meet strict standards and requirements to ensure that the molten steel can be transported safely and reliably under high temperature, high pressure and corrosive environment.

[0003] At present, after the existing ladles are loaded with molten steel, they are transported by hoisting them from the top with a crane, which causes shaking when pouring, easily causing the molten steel to splash out, posing a certain risk, and failing to ensure smooth unloading of the ladles, thus having certain defects. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a casting ladle with safe operation, which has the advantages of being able to improve the stability and safety of ladle unloading, and solves the problem that at present, when the ladle is unloaded, the ladle is lifted by a crane from above, which causes the ladle to shake, easily causing molten steel to splash out, and posing a certain risk.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting ladle with safe operation, comprising a ladle assembly and a stabilizing assembly, wherein the ladle assembly comprises a ladle body, a connecting rod is fixed on the side of the ladle body, a driver is fixed on one end of the connecting rod, and a stabilizing ring is movably hinged on the side of the connecting rod, a connecting rod is fixed on the stabilizing ring, a transverse beam is fixed on the connecting rod, a lifting ring is fixed on the transverse beam, and a mounting hole is opened on the side of the ladle body, the ladle body is used as a container for transferring and transporting molten steel, and is hung on the lifting ring by a hook of a crane to lift the ladle, and the driver is operated so that its output end drives the connecting rod to rotate, so that the ladle body tilts forward and the molten steel loaded inside is poured out.

[0008] The stabilizing component includes a stabilizing bottom plate movably connected to the bottom of the ladle body, a supporting block is fixed on the stabilizing bottom plate, an arc rod is movably sleeved in the supporting block, a mounting rod is fixed to one end of the arc rod, an L-shaped plate is threadedly connected to one end of the mounting rod, an arc plate is fixed to one end of the L-shaped plate, a mounting rod is fixed on the arc plate, one end of the mounting rod is threadedly connected to the mounting hole, the mounting rod and the connecting rod are located on the same horizontal line, and during the pouring process of the ladle, the stabilizing bottom plate is attached to the platform at the edge of the material cylinder, and the arc rod slides in the supporting block, so that the ladle can rotate smoothly, thereby improving the stability of pouring.

[0009] As a further improvement of the above solution, a suction cup is fixed to the bottom of the stable bottom plate, and a vacuum pump is fixed to the stable bottom plate, and the suction cup is communicated with the vacuum pump.

[0010] Through the above technical solution, when the device as a whole descends to unload materials, the stable bottom plate is attached to the edge of the unloading device or the workbench, the suction cup is attached to the contact surface, and the vacuum pump is used to evacuate air to completely adsorb the suction cup on the contact surface to fix the stable bottom plate. When the vacuum pump is supplying air, the suction cup is separated from the contact surface, and the device as a whole can be transferred at this time.

[0011] As a further improvement of the above scheme, the side of the supporting block is movably connected with a rotating knob, an adjusting screw is fixed to one end of the rotating knob, an extension rod is movably sleeved on one end of the adjusting screw, and an arc block is fixed to one end of the extension rod.

[0012] Through the above technical solution, by turning the rotating knob clockwise or counterclockwise, the front end of the regulating screw moves forward or backward, so that the arc block at the front end fits against the side of the arc rod to limit the speed.

[0013] As a further improvement of the above solution, a protective plate is fixed inside the arc block, and the protective plate is attached to the side of the arc rod.

[0014] Through the above technical solution, the side of the protective plate is smooth, which reduces the friction resistance between the contact surface with the arc rod and avoids the large resistance generated when the speed of the arc rod is limited, which leads to the wear of the arc rod.

[0015] As a further improvement of the above solution, a tension spring is movably sleeved on the side of the extension rod, and the tension spring is fitted between the regulating screw and the arc block.

[0016] Through the above technical solution, the tension spring has the function of expanding and pushing the arc block so that it can fit into the side of the arc block. By adjusting the screw to move forward, after the tension spring is tightened, one end pushes the arc block, increasing the pressure between the arc block and the arc rod, thereby playing a role in speed limiting.

[0017] As a further improvement of the above solution, a limit button is fixed to one end of the arc rod, and the limit button is fitted on the supporting block.

[0018] Through the above technical solution, the limit button is used to limit the rotation angle of the arc rod to avoid separation from the supporting block.

[0019] As a further improvement of the above solution, a spring rod is movably sleeved on the side of the arc rod, and the spring rod is fitted between the L-shaped plate and the supporting block.

[0020] Through the above technical solution, the spring rod has the function of expanding and pushing the supporting block, so that the other end of the supporting block fits against the side of the limit button. At this time, the supporting block and the stable bottom plate at the bottom are in the initial position, located directly below the ladle body.

[0021] As a further improvement of the above solution, a stabilizing slide groove is provided at the bottom of the arc-shaped plate, and the top of the supporting block is slidably connected in the stabilizing slide groove.

[0022] Through the above technical solution, when the ladle body is pouring, the arc plate rotates on the supporting block, and the supporting block slides in the stable slide groove, thereby improving the stability of the rotation and preventing the arc plate from detaching from the supporting block.

[0023] Compared with the prior art, the utility model provides a casting ladle with safe operation and has the following beneficial effects:

[0024] 1. The safe-to-operate casting ladle has a stabilizing component installed at the bottom of the ladle body. Before the ladle is unloaded, the crane is used to lay out the line so that the stabilizing bottom plate at the bottom of the ladle body fits the edge of the material cylinder or the workbench and is fixed by suction cups. When the ladle is tilted to unload, the arc plate and the arc rod slide on the supporting block, thereby effectively improving the stability of the ladle unloading.

[0025] 2. The safe-to-operate casting ladle is connected with a regulating screw through a threaded connection on the side of a supporting block. The length of the regulating screw in the supporting block is adjusted by rotating it clockwise or counterclockwise to control the pushing force of the tension spring so that the arc block at the front end is tightly attached to the side of the arc rod, thereby playing a speed limiting role and further improving the stability of the ladle body unloading.

[0037] The stabilizing component 2 includes a stabilizing bottom plate 201 movably connected to the bottom of the ladle body 101, a supporting block 204 is fixed on the stabilizing bottom plate 201, an arc rod 210 is movably sleeved in the supporting block 204, a mounting rod 213 is fixed at one end of the arc rod 210, an L-shaped plate 214 is threadedly connected to one end of the mounting rod 213, an arc plate 215 is fixed at one end of the L-shaped plate 214, a mounting rod 217 is fixed on the arc plate 215, one end of the mounting rod 217 is threadedly connected to the mounting hole 108, the mounting rod 217 and the connecting rod 102 are on the same horizontal line, during the pouring process of the ladle, the stabilizing bottom plate 201 is attached to the platform at the edge of the material cylinder, and the arc rod 210 slides in the supporting block 204, so that the ladle can rotate smoothly, thereby improving the stability of pouring.

[0038] The working principle of the safe casting ladle proposed in this embodiment is as follows: when in use, molten steel is conveyed into the ladle body 101. After loading, the ladle body 101 is transferred to the side of the cylinder container where the material is to be poured by a crane, and the crane is used to release the line so that the stable bottom plate 201 at the bottom is attached to the workbench at the edge of the cylinder container. At this time, the vacuum pump 203 is operated to pump air outward so that the suction cup 202 at the bottom is adsorbed on the table. At this time, the driver 103 is controlled to operate so that its output end drives the connecting rod 102 to rotate, so that the ladle body 101 gradually moves forward. Tilt, and at the same time, under the connecting action of the mounting rod 217, the arc plate 215 is fitted on the supporting block 204 and rotates, and the arc rod 210 slides in the supporting block 204, gradually and stably discharges the molten steel in the ladle body 101. After the discharge is completed, the vacuum pump 203 is controlled to deflate, and the device is lifted as a whole under the action of the crane line reeling. At this time, under the pushing force of the spring rod 211, the supporting block 204 drives the stable bottom plate 201 to return to the initial position (located at one end of the arc rod 210 and directly below the arc plate 215), waiting for the second discharge.

[0039] Furthermore, a suction cup 202 is fixed to the bottom of the stable base plate 201 , and a vacuum pump 203 is fixed to the stable base plate 201 , and the suction cup 202 and the vacuum pump 203 are interconnected.

[0040] More specifically, when the device as a whole descends to unload materials, the stable base plate 201 is attached to the edge of the unloading device or the workbench, and the suction cup 202 is attached to the contact surface. The vacuum pump 203 is used to evacuate air, so that the suction cup 202 is completely adsorbed on the contact surface to fix the stable base plate 201. When the vacuum pump 203 supplies air, the suction cup 202 is separated from the contact surface, so that the device as a whole can be transferred.

[0041] Furthermore, a rotating knob 205 is movably connected to the side of the supporting block 204 , an adjusting screw 206 is fixed to one end of the rotating knob 205 , an extension rod 207 is movably sleeved on one end of the adjusting screw 206 , and an arc block 208 is fixed to one end of the extension rod 207 .

[0042] More specifically, by rotating the rotating knob 205 clockwise or counterclockwise, the front end of the regulating screw rod 206 moves forward or backward, so that the arc block 208 at the front end fits against the side of the arc rod 210 to limit the speed.

[0043] In addition, it should be further explained that the side of the arc block 208 is semicircular and matches the diameter of the side of the arc rod 210 , thereby improving the stability of the arc rod 210 sliding in the arc block 208 .

[0044] Furthermore, a protective plate 2081 is fixed inside the arc block 208 , and the protective plate 2081 is attached to the side of the arc rod 210 .

[0045] More specifically, the side of the protection plate 2081 is smooth, which reduces the friction resistance between the contact surface with the arc rod 210 and avoids the large resistance generated when the speed of the arc rod 210 is limited, resulting in the wear of the arc rod 210.

[0046] Furthermore, a tension spring 209 is movably sleeved on the side of the extension rod 207 , and the tension spring 209 is fitted between the regulating screw 206 and the arc block 208 .

[0047] More specifically, the tension spring 209 has the function of expanding and pushing the arc block 208 so that it can fit against the side of the arc block 208. By adjusting the screw 206 to move forward, the tension spring 209 is tightened, and one end pushes the arc block 208, increasing the pressure between the arc block 208 and the arc rod 210, thereby playing a speed limiting role.

[0048] Furthermore, a limit button 212 is fixed to one end of the arc rod 210 , and the limit button 212 is attached to the supporting block 204 .

[0049] More specifically, the limit button 212 is used to limit the rotation angle of the arc rod 210 to prevent it from being separated from the supporting block 204.

[0050] Furthermore, a spring rod 211 is movably sleeved on the side of the arc rod 210 , and the spring rod 211 is fitted between the L-shaped plate 214 and the supporting block 204 .

[0051] More specifically, the spring rod 211 has the function of expanding and pushing the supporting block 204 so that the other end of the supporting block 204 is attached to the side of the limit button 212. At this time, the supporting block 204 and the stable bottom plate 201 at the bottom are in the initial position, located directly below the ladle body 101.

[0052] Furthermore, a stabilizing groove 216 is formed at the bottom of the arc-shaped plate 215 , and the top of the supporting block 204 is slidably connected in the stabilizing groove 216 .

[0053] More specifically, when the ladle body 101 is being poured, the arc plate 215 rotates on the support block 204 , and the support block 204 slides in the stable slide groove 216 , thereby improving the stability of the rotation and preventing the arc plate 215 from detaching from the support block 204 .

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
