Description

Technical Field

[0001] This utility model relates to the field of molten iron ladle capping technology, specifically to a gantry-type capping device. Background Technology

[0002] The torpedo-type molten iron ladle car is a specialized transport vehicle for carrying molten iron at high temperatures to steelmaking and foundries. The component carrying the molten iron on the torpedo-type ladle car is the molten iron ladle, which is traditionally transported open. During transportation, the majority of the heat loss from the molten iron is due to heat dissipation from the ladle, causing significant air pollution. Adding an insulated cover to the molten iron ladle can significantly reduce this radiative heat loss; reduce the temperature drop of the molten iron; reduce air pollution; and simultaneously reduce the precipitation of cold slag inside the ladle. Furthermore, the temperature of the ladle lining is stabilized, saving on the amount of heating alloys and oxygen required for heating the molten iron during steelmaking, ultimately achieving energy conservation and emission reduction, and improving economic efficiency.

[0003] In the existing technology, the heat insulation cover is generally an integral structure with the molten iron ladle. When adding or removing the cover, the heat insulation cover has a large range of movement, and the integral structure is not convenient for subsequent operations such as moving the molten iron ladle and pouring liquid. Therefore, a gantry-type cover device with separate ladle and cover is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a gantry-type cover device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gantry-type cover-adding device, comprising a gantry frame and a heat-insulating cover placement rack, a guide rail mounted on the gantry frame, a transverse traveling mechanism slidably mounted on the guide rail, a lifting mechanism mounted on the transverse traveling mechanism, a lower frame connected to the extended end of the lifting mechanism, a gripping mechanism connected to the lower end of the lower frame for picking up and placing the heat-insulating cover, and a longitudinal traveling mechanism mounted at the lower end of the gantry frame.

[0006] Preferably, the insulation cover placement rack is positioned between two longitudinal traveling mechanisms. The longitudinal traveling mechanisms drive the gantry frame to move so that it aligns with the insulation cover placement rack. Then, the transverse traveling mechanism drives the lifting mechanism and the gripping mechanism to move to the upper end of the insulation cover placement rack. Finally, the lifting mechanism drives the gripping mechanism to descend, so that the gripping mechanism can grip the insulation cover on the insulation cover placement rack and perform the covering operation.

[0007] Preferably, the lower frame is connected to the gripping mechanism by a hinge.

[0008] Preferably, a distance sensor for detecting the distance between the lower frame and the gripping mechanism is installed at the bottom of the lower frame, and a mechanical proximity switch is installed at the bottom of the lower frame for braking the lifting mechanism in the event of a malfunction of the distance sensor, thereby limiting the descent of the lower frame.

[0009] Preferably, a mobile trolley is slidably mounted on the guide rail, and an electric hoist is installed on the mobile trolley to suspend and grab the grabbing mechanism via the hook of the electric hoist.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: A gantry-type lid-adding device, through the lateral walking mechanism, lifting mechanism, lower frame, and gripping mechanism set on the gantry, can not only ensure the temperature loss inside the molten iron ladle after lid-adding, but also facilitate the pouring out of the molten iron after the lid is removed. The distance sensor set between the lower frame and the gripping mechanism can detect the distance between the lower frame and the gripping mechanism to determine whether the gripping mechanism has descended to the correct position, so as to grab the insulation lid on the insulation lid placement rack, separate the ladle from the lid, and store the insulation lid on the insulation lid placement rack for easy storage or retrieval. When removing the insulation lid from the molten iron ladle, the lower frame and the gripping mechanism are connected by a hinge, so that when there is an obstruction at the mouth of the molten iron ladle, the insulation lid is tilted, and the gripping mechanism can also land on the tilted insulation lid and grab it, so that it can adapt to different tilt states of the insulation lid and increase the convenience of use.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a gantry-type cover-adding device, including a gantry frame 1 and an insulation cover placement rack 2. A guide rail 3 is installed on the gantry frame 1, a transverse traveling mechanism 4 is slidably installed on the guide rail 3, a lifting mechanism 5 is installed on the transverse traveling mechanism 4, a lower frame 6 is connected to the extended end of the lifting mechanism 5, a gripping mechanism 7 is connected to the lower end of the lower frame 6 for picking up and placing insulation covers 8, and a longitudinal traveling mechanism 9 is installed at the lower end of the gantry frame 1.

[0018] The insulation cover placement rack 2 is set between two longitudinal traveling mechanisms 9. The longitudinal traveling mechanism 9 drives the gantry frame 1 to move so that it corresponds to the insulation cover placement rack 1. Then, the transverse traveling mechanism 4 drives the lifting mechanism 5 and the gripping mechanism 7 to move to the upper end of the insulation cover placement rack 2. Then, the lifting mechanism 5 drives the gripping mechanism 7 to descend so that the gripping mechanism 7 can grip the insulation cover 8 on the insulation cover placement rack 2 to perform the covering operation.

[0019] like Figure 1 As shown, there can be two heat insulation cover placement racks 2. The length of the gantry crane beam is 21.1 meters. The gantry cranes 1 are connected by three rails for transporting molten iron ladles. The heat insulation cover placement racks 2 are distributed between the three molten iron ladles. The transverse walking mechanism 4, the lifting mechanism 5, the lower frame 6, and the grabbing mechanism 7 are set into two sets.

[0020] like Figure 2 As shown, the number of heat preservation cover placement racks 2 can be one, where the length of the gantry crane beam is 20.3 meters. Two rails are used to transport molten iron ladles between the gantry cranes 1. The heat preservation cover placement rack 2 is located between two molten iron ladles, and the transverse walking mechanism 4, lifting mechanism 5, lower frame 6 and grabbing mechanism 7 are set as two sets.

[0021] like Figure 3 As shown, the number of heat preservation cover placement racks 2 can be one, where the length of the gantry crane beam is 18.5 meters. Two rails are used to transport molten iron ladles between the gantry cranes 1. The heat preservation cover placement rack 2 is located on the side near the longitudinal end of the gantry crane 1, and the transverse walking mechanism 4, lifting mechanism 5, lower frame 6 and grabbing mechanism 7 can be set as one group.

[0022] The lateral translation mechanism 4 is a track-walking mechanism that moves laterally within the guide rail 3. This is a well-known technical means in the prior art, so it will not be described in detail here.

[0023] The longitudinal traveling mechanism 9 is a track traveling mechanism that drives the gantry 1 to move longitudinally on the track.

[0024] The lifting mechanism 5 includes an upper frame, a motor, a commutator, a coupling, and a screw jack. The motor is mounted on the upper frame, and the output end of the motor is connected to the screw jacks mounted at the four corners of the upper frame through couplings and commutators. The motor controls the lifting of the four screw jacks simultaneously, and the extended end of the screw jack is connected to the lower frame.

[0025] A backup motor is also installed on the upper frame. The backup motor is connected to the commutator of the motor and is used to start the backup motor for use when the motor is not working.

[0026] The minimum spacing between the upper frame and the lower frame 6 is 10mm.

[0027] The gripping mechanism 7 includes a mechanical claw, a telescopic mechanism, a mechanical claw guide rail, wheels, and a frame. The mechanical claw guide rail is mounted on the frame, and the wheels are mounted on both longitudinal sides of the mechanical claw and slide within the mechanical claw guide rail. The telescopic mechanism is installed between the two mechanical claws. When the telescopic mechanism is activated, it controls the mechanical claw to move linearly within the mechanical claw guide rail, causing the two mechanical claws to move closer to each other to grip or move away from each other, thereby performing the removal and addition of the insulation cover 8.

[0028] The lower frame 6 is connected to the gripping mechanism 7 by a hinge 10. The hinge 10 is used here to allow the lower frame 6 to continue descending after the gripping mechanism 7 and the upper end of the gripping mechanism 7 are in contact with the upper end of the gripping mechanism 8, depending on the number of gripping covers 8 stacked on the gripping cover placement rack 2 and the different descent height of the lifting mechanism 5. Moreover, since molten iron blocks are prone to form at the filling port of the molten iron ladle, the gripping cover 8 may be tilted due to the restriction of the molten iron blocks. The hinge 10 connection will not prevent the gripping mechanism 7 from being unable to descend due to the obstruction of the molten iron blocks. If a straight rod connection is used, the gripping mechanism 7 is prone to collision with the gripping cover 8.

[0029] The bottom of the lower frame 6 is equipped with a distance sensor 11 for detecting the distance between the lower frame 6 and the gripping mechanism 7, and a mechanical proximity switch 12 is also installed at the bottom of the lower frame 6 to brake the lifting mechanism in the event of a malfunction of the distance sensor 11, thereby limiting the descent of the lower frame 6.

[0030] A mobile trolley 13 is slidably mounted on the guide rail 3. An electric hoist 14 is installed on the mobile trolley 13. The hook of the electric hoist 14 is used to suspend the grabbing mechanism 7 through the hinge. This is used for emergency handling after the lifting mechanism 5 and the grabbing mechanism 7 malfunction, so as to promptly remove or cover the heat preservation cover 8 from the molten iron ladle filling port.

[0031] A gripping seat is installed at the upper end of the heat insulation cover 8, and the gripping seat is lower than the upper surface of the heat insulation cover 8 to avoid affecting the stacking of the heat insulation cover 8.

[0032] Working principle: When this utility model is in use, if a cover needs to be added, the horizontal walking mechanism 4 is activated. The horizontal walking mechanism 4 drives the lifting mechanism 5 and the gripping mechanism 7 to move to the upper end of the heat preservation cover placement rack 2. Then, the lifting mechanism 5 is activated, causing the lower frame 6 to descend, so that the gripping mechanism 7 connected by the hinge 10 fits against the uppermost heat preservation cover 8 placed on the heat preservation cover placement rack 2. The distance between the lower frame 6 and the gripping mechanism 7 is monitored by the set distance sensor 11 to ensure that the gripping mechanism 7 can fall smoothly onto the heat preservation cover 8. Then, the gripping mechanism 7 grips the heat preservation cover 8. Then, the lifting mechanism 5 is controlled to rise, driving the gripping mechanism 7 and the gripped heat preservation cover 8 to rise. Then, the horizontal walking mechanism 4 and the vertical walking mechanism 9 are controlled to adjust the position of the heat preservation cover 8 so that it corresponds to the filling mouth of the molten iron ladle for the cover addition operation.

[0033] When it is necessary to remove the cover, the horizontal traveling mechanism 4 and the vertical traveling mechanism 9 are activated so that the lifting mechanism 5 and the gripping mechanism 7 are aligned with the upper end of the heat preservation cover 8. Then, the lifting mechanism 5 is controlled to descend, which drives the lower frame 6 and the gripping mechanism 7 to descend until the gripping mechanism 7 is in contact with the heat preservation cover 8. The gripping mechanism 7 is controlled to grip the heat preservation cover 8. Then, the lifting mechanism 5 is raised to drive the gripping mechanism 7 to lift the heat preservation cover 8 at the mouth of the molten iron ladle, thereby performing the cover removal operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
