Description

Technical Field

[0001] This utility model relates to a long-distance, high-drop lifting and transfer device for high-temperature aluminum liquid ladle in the aluminum smelting and aluminum processing industry, and particularly to a guide-type aluminum liquid ladle transfer hoist. Background Technology

[0002] In the aluminum electrolysis production process, molten aluminum needs to be continuously transported from the aluminum electrolysis workshop to the casting workshop for the next process. When there is a large height difference between the aluminum electrolysis workshop and the casting workshop, special lifting equipment is required, along with overhead cranes, to lift and transfer the molten aluminum ladle.

[0003] A lifting and transferring device for an aluminum ladle is disclosed in Chinese patent CN222249814U. In this device, a hook is hinged to a hanger, and an electric or hydraulic drive device is installed on the hanger to open and close the hook, thereby clamping or releasing the ladle holder. However, while solving the problem, this lifting and transferring device for an aluminum ladle has the following drawbacks: It can only clamp and fix a ladle rack of one width. For narrower ladle racks, the lifting hook cannot stably hook onto the bottom of the ladle rack. For wider ladle racks, the bottom of the lifting hook is tilted and cannot stably hook onto the bottom of the ladle rack. Therefore, the lifting device in this aluminum ladle lifting and transfer device has a narrow range of applications. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0005] Therefore, one objective of this utility model is to propose a guide-type aluminum liquid ladle transfer lifting device, which aims to solve the problem that the lifting devices in the existing aluminum liquid ladle lifting and transfer devices have a narrow range of applications and cannot be used for aluminum liquid ladles of different sizes.

[0006] To achieve the above objectives, one embodiment of this utility model provides a guide-type aluminum liquid platform transfer hoist, including a grid-shaped guide frame, a Y-axis adjustment mechanism fixed below the grid-shaped guide frame, and X-axis adjustment mechanisms installed on both sides of the Y-axis adjustment mechanism; the grid-shaped guide frame includes a grid frame, the top of which is fixed with four pulleys by bolts, and a crossbeam welded to the middle of the grid frame; the Y-axis adjustment mechanism includes a housing, inside which two sets of Y-axis telescopic rods are slidably connected, each set including two Y-axis telescopic rods, and a first transmission assembly for driving the extension and retraction of the Y-axis telescopic rods is installed on the Y-axis adjustment mechanism; the X-axis adjustment mechanism includes two housings, inside which two X-axis telescopic rods are slidably connected, and the ends of the X-axis telescopic rods are fixed with hooks, and a second transmission assembly for driving the extension and retraction of the X-axis telescopic rods is installed on the top of the housings.

[0007] The beneficial effects are: the Y-axis adjustment mechanism can adjust the distance between the two X-axis adjustment mechanisms, and the two X-axis adjustment mechanisms can adjust the distance between the two relative hanger hooks. Thus, the cooperation of the Y-axis adjustment mechanism and the X-axis adjustment mechanism can clamp and fix aluminum liquid ladles of different sizes, so it has a wide range of applications.

[0008] In a preferred embodiment, L-shaped guide plates are fixedly connected to each of the four corners of the grid frame, and guide wheels are installed on the inner walls of both sides of the L-shaped guide plates, with at least two guide wheels installed on the inner wall of each side of the L-shaped guide plates.

[0009] The beneficial effects are as follows: During the lifting process, firstly, the four L-shaped guide plates are fitted inside the four guide rails, which can limit the movement of the lifting device and ensure the stability of the aluminum liquid platform lifting; secondly, the guide wheels on the inner wall of the L-shaped guide plates allow the L-shaped guide plates to lift and lower along the guide rollers, which can avoid the problem of large noise caused by static metal friction between the L-shaped guide plates and the guide rails.

[0010] Furthermore, the crossbeam and the housing are fixed together by multiple Z-shaped plates, thereby fixing the Y-axis adjustment mechanism below the grid-shaped guide frame.

[0011] Furthermore, the first transmission assembly includes two vertical transmission shafts, which are rotatably connected to the housing through bearings. Each transmission shaft is located between the two Y-shaped telescopic rods in each group. A gear is fixed on the outer surface of the transmission shaft, and a rack that meshes with the gear is fixed on the opposite side of the two Y-shaped telescopic rods in each group.

[0012] Furthermore, a first geared motor is installed at the bottom of the housing, and the output shaft of the first geared motor is connected to one of the transmission shafts via a coupling. The bottom ends of both transmission shafts are keyed to sprockets, and the two sprockets are driven by chains.

[0013] Furthermore, the end of the Y-direction telescopic rod is fixed with a Y-shaped fixing frame by bolts, and the inner walls on both sides of the Y-shaped fixing frame are respectively fixed to the two side walls of the housing.

[0014] Furthermore, the second transmission assembly includes two ball screws, the screws of the two ball screws are rotatably connected to the top of the housing two through bearing seats, the nut structure of the ball screws is fixed together with the top of the X-direction telescopic rod, and a dual output shaft reduction motor is installed in the middle of the upper part of the housing two, the two output shafts of the dual output shaft reduction motor are respectively connected to the screws of the two ball screws.

[0015] Furthermore, a third housing is installed on the top of the second housing to cover the ball screw and prevent dust.

[0016] In a preferred embodiment, a proximity switch is installed on the inner side of the hanger hook.

[0017] The beneficial effect is that when clamping the table bag frame, the proximity switch is triggered after it comes into contact with the table bag frame, causing the dual output shaft geared motor to stop driving, thereby avoiding the problem of the hanger hook excessively clamping the table bag frame, which could lead to deformation of the hanger hook or overload damage to the dual output shaft geared motor.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides a guide-type aluminum liquid platform transfer hoist. Example 1:

[0028] like Figure 1 As shown, it includes a grid-shaped guide frame 1, a Y-axis adjustment mechanism 2, and an X-axis adjustment mechanism 3.

[0029] like Figure 2 As shown, the grid-shaped guide frame 1 includes a grid frame 11, four pulleys 12 fixed to the grid frame 11 by bolts, a crossbeam 13 welded to the middle of the grid frame 11, and L-shaped guide plates 14 welded to the four corners of the grid frame 11. Guide wheels 15 are installed on the inner walls of both sides of the L-shaped guide plate 14, and at least two guide wheels 15 are installed on the inner wall of each side of the L-shaped guide plate 14.

[0030] like Figure 1 and Figure 3 As shown, the Y-axis adjustment mechanism 2 includes a housing 21, a crossbeam 13, and multiple Z-shaped plates 6 welded to both sides of the housing 21. The Z-shaped plates 6 fix the grid-shaped guide frame 1 and the Y-axis adjustment mechanism 2 together. A partition is fixed inside the housing 21, dividing the housing 21 into two cavities. Two Y-axis telescopic rods 22 are slidably connected in each cavity. A vertical transmission shaft 4 is rotatably connected in each cavity through a bearing. Each transmission shaft 4 is located between the two Y-axis telescopic rods 22 in the cavity. A gear 41 is fixed on the outer surface of the transmission shaft 4. A rack 42 that meshes with the gear 41 is fixed on the opposite side of the two Y-axis telescopic rods 22 in each cavity. By rotating the transmission shaft 4, the two Y-axis telescopic rods 22 can be extended or retracted into the housing 21 in opposite directions. like Figure 5As shown, a geared motor 43 is installed below the housing 21, and the output shaft of the geared motor 43 is connected to one of the transmission shafts 4 via a coupling. The bottom ends of the two transmission shafts 4 are keyed to sprockets 44, and the two sprockets 44 are driven by chains 45.

[0031] like Figure 3 As shown, the X-axis adjustment mechanism 3 includes two housings 31. The ends of the Y-axis telescopic rod 22 are fixed with Y-shaped fixing brackets 23 by bolts. The inner walls on both sides of the Y-shaped fixing brackets 23 are fixed to the two side walls of the housing 31 respectively. Two X-axis telescopic rods 32 are slidably connected inside the housing 31, and the ends of the X-axis telescopic rods 32 are fixed with hanger hooks 33. like Figure 4 As shown, two ball screws 5 are connected to the top of housing 2 31 via bearing seats. Housing 3 34 is installed on the top of housing 2 31 to cover the ball screws 5 and prevent dust. The two ball screws 5 are located above the two X-direction telescopic rods 32 inside housing 2 31, and the nut structure of the ball screw 5 is fixed to the top of the X-direction telescopic rod 32. A dual-output shaft geared motor 51 is installed in the middle of the top of housing 2 31. The two output shafts of the dual-output shaft geared motor 51 are connected to the screws of the two ball screws 5, so that the dual-output shaft geared motor 51 can drive the screws of the ball screws 5 to rotate, so that the nuts of the ball screws 5 drive the X-direction telescopic rods 32 to perform telescopic movement.

[0032] The working principle of this embodiment is as follows: In use, four pulleys 12 are connected to the wire rope of the winch for raising and lowering the lifting device. The Y-axis adjustment mechanism 2 is driven by the first transmission component, causing the Y-axis telescopic rod 22 to extend and retract, thereby adjusting the distance between the two X-axis adjustment mechanisms 3. The X-axis adjustment mechanism 3 is driven by the second transmission component, causing the X-axis telescopic rod 32 to extend and retract, thereby adjusting the distance between the two relative lifting hooks 33. Thus, the cooperation of the Y-axis adjustment mechanism 2 and the X-axis adjustment mechanism 3 can clamp and fix aluminum liquid platform ladles of different sizes. Example 2:

[0033] like Figure 3 As shown, based on Embodiment 1, a proximity switch 35 is installed on the inner side of the hanger hook 33. When clamping the table bag frame, the proximity switch 35 is triggered after it comes into contact with the table bag frame, causing the dual output shaft geared motor 51 to stop driving. This avoids the hanger hook 33 from excessively clamping the table bag frame, which could lead to deformation of the hanger hook 33 or overload damage to the dual output shaft geared motor 51.
