Description

Technical Field

[0001] The utility model relates to the technical field of molten iron ladle slag cleaning mechanisms, in particular to a hot ladle slag cleaning machine. Background Art

[0002] Large-scale calcium-silicon electric furnace refers to a calcium-silicon electric furnace with a capacity of more than 16,500 kVA. The temperature of the furnace during smelting and tapping is as high as 1900-2100℃. The high-melting-point slag containing SiC and CaC2 is frequently discharged with the molten iron and poured into the ladle. Since the specific gravity of the slag is greater than that of the calcium-silicon solution, the slag quickly sinks to the bottom of the ladle after pouring. After condensing to 1200℃, the slag adheres to the bottom and wall of the ladle. Due to the high hardness of the slag and the high temperature of the operating environment, the labor intensity of manual ladle cleaning is high. If the ladle lining is repeatedly exposed to extreme cold, extreme heat and oxidation when cleaning after cooling, its service life will be reduced. Utility Model Content

[0003] In order to solve the above-mentioned problem that manual slag cleaning is dangerous and difficult, the utility model provides a hot ladle slag cleaning machine.

[0004] The technical solution of this utility model is as follows:

[0005] A hot ladle slag cleaning machine comprises a guide rail arranged along a preset path, and a moving trolley is arranged on the guide rail;

[0006] The upper surface of the mobile trolley is a horizontal plane and is provided with a rotating platform. A multi-stage telescopic beam is provided above the rotating platform. A connecting rod adjustment mechanism is provided between the multi-stage telescopic beam and the rotating platform. The multi-stage telescopic beam can be raised and lowered and tilted on a vertical plane relative to the rotating platform.

[0007] The extended end of the multi-stage telescopic beam is connected to a slag scraper head through a transition rod, and the transition rod is detachably connected to the multi-stage telescopic beam, and the slag scraper head is detachably connected to the transition rod;

[0008] The slag scraping head is arranged obliquely relative to the multi-stage telescopic beam.

[0009] The slag removal head is controlled by a multi-stage telescopic mechanism to extend into the ladle for slag removal. The operator can stay away from the working position, which is safer. The metal structure can extend into the ladle, so slag removal can be performed in a high temperature environment, and there is no need to wait for the cooling process.

[0010] The structure of the multi-stage telescopic beam is that the multi-stage telescopic beam includes an outer beam fixed to a connecting rod adjustment mechanism, the outer beam is telescopically connected to a middle beam, the middle beam is telescopically connected to an inner beam, and the middle beam and the inner beam extend in the same direction. The outer beam as a basic structure can be rotated and lifted on multiple planes to be suitable for various application scenarios, and the telescopic structure can complete the slag cleaning action while occupying less space when the machine is restricted.

[0011] The transition rod is connected to the slag scraper head in such a way that the inner beam extension end is connected to the transition rod through a flange structure, and the end of the transition rod away from the inner beam is connected to the slag scraper head. The transition rod can be replaced with a different length or other specifications as required, and the slag scraper head can also be replaced separately after being damaged.

[0012] The way to achieve the tilting of the scraper head is that the two fixed planes of the transition rod are tilted relative to each other. By selecting transition rods with different specifications, the scraper head can be tilted to a suitable angle, so the degree of freedom is higher and it can be applied to more application scenarios.

[0013] In order to achieve slag removal, the lower end of the slag removal head is arranged below the inner beam, so as to ensure that the inner beam can contact the bottom surface of the ladle and remove slag after it extends into the ladle.

[0014] In order to prevent the moving trolley from moving during operation, the moving trolley is provided with a locking mechanism arranged opposite to the guide rail, and the locking mechanism can clamp the guide rail.

[0015] The specific structure of the locking mechanism is that the locking mechanism includes two clamping members located on both sides of the guide rail, and the two clamping members are driven to rotate by the telescope, and the rotation direction is the direction of approaching or moving away from the guide rail.

[0016] The specific structure of the above connecting rod adjustment structure is that the connecting rod adjustment mechanism includes a reference seat fixed to the rotary platform, and the reference seat is provided with a tilting electric cylinder and a lifting electric cylinder respectively connected to the multi-stage telescopic beam through connecting rods.

[0017] The structure of the telescopic connection between the outer beam and the middle beam is that the outer beam includes a rail beam, the middle beam can move along the rail beam, and a driving motor and a gear are arranged at both ends of the rail beam, a transmission belt is arranged between the driving motor and the gear, the rail beam is connected to the transmission belt, and a plurality of guide wheels are arranged around the circumference of the middle beam on one side of the rail beam close to the extension end of the middle beam. The setting of the guide wheels can prevent the middle beam from deviating from the preset path, and the driving method of the transmission belt can achieve full telescopic movement.

[0018] As a preferred solution, the multi-stage telescopic beam is provided with an inclination sensor, so that the actual inclination can be known during remote operation, which is convenient for control.

[0019] The beneficial effects of the utility model are as follows: the utility model is a hot ladle slag cleaning machine, which can replace the existing manual slag removal operation, and the device is made of metal material, can directly extend into the molten iron ladle at high temperature to remove slag, and the device has a multi-stage telescopic function, which can effectively extend the slag removal range, and in conjunction with the use of a rotating platform and a connecting rod adjustment mechanism, it can rotate and lift in multiple planes, and thus can complete the slag removal operation in a variety of application scenarios, and the slag removal head of the device is connected by a transition rod, which can be replaced separately, and can also be selected according to actual needs. Transition rods of different specifications are selected for connection to meet various application requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1-5 A hot ladle slag cleaning machine shown in the figure includes a guide rail 1 arranged along a preset path, and the guide rail 1 is arranged in two parallel groups to ensure that a supporting effect can be achieved. Afterwards, a mobile trolley 2 is arranged on the guide rail 1, and the mobile trolley 2 can move along the length direction of the guide rail 1, and can then switch between multiple positions. It can be moved to the ladle position when working, and can be moved to a position that does not affect other operations in other time periods.

[0032] It should be noted that if Figure 1 As shown, the upper surface of the mobile trolley 2 is a horizontal plane, and a rotating platform 4 is provided. The rotating platform 4 can rotate, so it can drive the structure above the rotating platform 4 to rotate relative to the mobile trolley 2 on the horizontal plane. For this purpose, a multi-stage telescopic beam is provided above the rotating platform 4, so the multi-stage telescopic beam can rotate in the horizontal direction. However, for the operation of different equipment, height and angle are issues that need to be considered. In order to improve applicability, it is necessary, such as Figure 6 As shown, a connecting rod adjustment mechanism 5 is provided between the multi-stage telescopic beam and the rotating platform 4. The purpose of providing the connecting rod adjustment mechanism 5 is to enable the multi-stage telescopic beam to be lifted and lowered relative to the rotating platform 4 and to be tilted on a vertical plane.

[0033] The specific structure of the connecting rod adjustment structure is that the connecting rod adjustment mechanism 5 includes a reference seat 51 fixed to the rotating platform 4, and the reference seat 51 is provided with a tilting electric cylinder 52 and a lifting electric cylinder 53, which are respectively connected to the multi-stage telescopic beam through a connecting rod. The multi-stage telescopic beam can be controlled to change its angle in the vertical direction by controlling the tilting electric cylinder 52, and the multi-stage telescopic beam can be changed in height position by controlling the lifting electric cylinder 53. The above two adjustment methods are combined with the rotating platform 4 to enable the multi-stage telescopic beam to rotate in the horizontal and vertical planes and change its height, so it can be applied to most application scenarios. The above connecting rod adjustment mechanism 5 has a specific structural introduction in the patent previously applied for and authorized by the company, so it will not be repeated here. The purpose is to obtain the adjustment function.

[0034] Afterwards, in order to complete the slag removal operation, the extended end of the multi-stage telescopic beam is connected to a slag removal head 10 through a transition rod 9, and the transition rod 9 is detachably connected to the multi-stage telescopic beam, and the slag removal head 10 is detachably connected to the transition rod 9, and in the above structure, the slag removal head 10 is tilted relative to the multi-stage telescopic beam. It should be noted that the slag removal head 10 needs to perform slag removal operations in a high temperature environment and needs to be docked with the slag. Therefore, after long-term use, the slag removal head 10 is prone to damage. If most of the parts are replaced only by the damage of the slag removal head 10, the cost is high. For this reason, the slag removal head 10 needs to be set as a separately detachable structure.

[0035] like Figure 6 As shown, the transition rod 9 is connected to the slag scraper head 10 in the following manner: the extending end of the inner beam 8 is connected to the transition rod 9 through a flange structure, and the end of the transition rod 9 away from the inner beam 8 is connected to the slag scraper head 10. The transition rod 9 can be replaced with a length specification or other specifications as required, and the slag scraper head 10 can also be replaced separately after being damaged.

[0036] In order to facilitate the adjustment of the structure according to the needs, the way to achieve the tilting setting of the slag scraper head 10 is that the two fixed planes of the transition rod 9 are relatively tilted. By selecting transition rods 9 with different specifications, the slag scraper head 10 can be tilted to a suitable angle, so the degree of freedom is higher and it can be applied to more application scenarios. In addition, the length of the transition rod 9 can be set to multiple specifications for free selection, and the angle specifications of the two fixed planes can also be set to multiple specifications for free selection, so as to ensure that the slag scraper head 10 can obtain the best scraping angle and position.

[0037] It should be noted that in the above structure, in order to achieve slag removal, the lower end of the slag removal head 10 is set lower than the inner beam 8. It is ensured that the inner beam 8 can contact the bottom surface of the ladle and remove slag after it extends into the ladle.

[0038] The above structure can be used to control the slag removal head 10 to extend into the ladle for slag removal through the multi-stage telescopic mechanism, so that the operator can stay away from the working position, which is safer, and the metal structure can extend into the ladle, so that slag removal can be performed in a high temperature environment, and there is no need to wait for the cooling process. Compared with the existing manual slag removal method, it is safer and not affected by temperature, and is not affected by the slag removal operation environment. Within a certain range, it can be freely adjusted according to needs.

[0039] As an implementation method, Figure 3 , 4 As shown, the structure of the multi-stage telescopic beam is that the multi-stage telescopic beam includes an outer beam 6 fixed to a connecting rod adjustment mechanism 5, the outer beam 6 is telescopically connected to a middle beam 7, the middle beam 7 is telescopically connected to an inner beam 8, and the middle beam 7 and the inner beam 8 have the same extension direction. The outer beam 6 as a basic structure can be rotated and lifted on multiple planes to be suitable for various application scenarios, and the telescopic structure can complete the slag cleaning action while occupying less space when the machine is restricted.

[0040] In the above structure, the structure of the telescopic connection between the outer beam 6 and the middle beam 7 is that the outer beam 6 includes a rail beam 61, the middle beam 7 can move along the rail beam 61, and a driving motor 62 and a gear are provided at both ends of the rail beam 61, a transmission belt is provided between the driving motor 62 and the gear, the rail beam 61 is connected to the transmission belt, and a plurality of guide wheels 63 are provided around the middle beam 7 on one side of the rail beam 61 close to the extended end of the middle beam 7. The provision of the guide wheels 63 can prevent the middle beam 7 from deviating from the preset path, and the driving mode of the transmission belt can achieve full telescopic movement.

[0041] The connection method between the middle beam 7 and the inner beam 8 can also adopt the above method, the purpose is to achieve multi-level changes.

[0042] As another example, Figure 7 As shown, in order to prevent the moving trolley 2 from moving during the working process, the moving trolley 2 is provided with a locking mechanism 3 arranged opposite to the guide rail 1 , and the locking mechanism 3 can clamp the guide rail 1 .

[0043] The specific structure of the locking mechanism 3 is that the locking mechanism 3 includes two clamping members 32 located on both sides of the guide rail 1 , and the two clamping members 32 are driven to rotate by the telescope 31 , and the rotation direction is the direction of approaching or moving away from the guide rail 1 .

[0044] Finally, due to the influence of high temperature environment, operators are generally unable to operate on site. In order to improve the operating experience, the multi-stage telescopic beam is provided with an inclination sensor 11. During the remote operation, the actual inclination can be understood for easy control.
