[0002] Torpedo ladles are crucial equipment in steel plants for transporting molten iron at high temperatures. During transport, the open ladle opening generates carbon emissions and causes smoke and dust pollution, while also lowering the molten iron temperature and resulting in energy loss. Therefore, most current torpedo ladles are equipped with lids to seal the ladle opening. These lids require specialized drive mechanisms for opening and closing. However, existing drive mechanisms suffer from high failure rates, difficult maintenance, and potential production delays in practical use. Summary of the Invention

[0041] The specific technical solutions of this application will be described in detail below with reference to the accompanying drawings, which are not necessarily drawn to scale.

The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0042] It should be noted that this application is based on the inventor's discovery and understanding of the following facts and problems:

[0043] In existing technologies, the lifting transmission device of torpedo canisters mostly adopts an electro-hydraulic actuator and connecting rod drive, with the connecting rod connecting between the electro-hydraulic actuator and the cover. In use, the extension and retraction of the electro-hydraulic actuator can drive the connecting rod to move, and the moving connecting rod can drive the cover to move up and down, thus meeting the needs of driving the cover to close and open.

[0044] However, due to the harsh working conditions on site, such as high temperatures and dust, the electro-hydraulic actuator is prone to scratches on the hydraulic cylinder rod, which can easily lead to oil leakage and malfunctions during use.

[0045] Secondly, during the driving process, the connecting rod's running trajectory is arc-shaped, meaning the connecting rod swings up and down around the connection point with the electro-hydraulic actuator. This swinging action generates a vertical force component. Under the action of this force component, the mechanical parts of the lifting transmission device often experience damage to the electro-hydraulic actuator, wear and jamming at the hinge position of the connecting rod mechanism, etc. Furthermore, it can easily cause mechanical failures such as damage to the actuator seal. Moreover, due to the relatively complex overall structure, there are no directly replaceable structural parts on site, making overall maintenance and repair very inconvenient and prone to delaying production.

[0046] Based on the above facts and problems, this application provides a torpedo canister cover driving device.

[0047] The following describes an embodiment of the torpedo canister cover driving device (hereinafter referred to as the driving device) of this application.

[0048] like Figure 1 As shown, the drive device of this application includes a base 1, a cover assembly 2, a swing member 3, multiple steering members 4, a flexible member 5, and a driver 6.

[0049] The base 1 is installed on the torpedo canister. For example, as... Figure 1 As shown, the base 1 can be a casting, and the base 1 as a whole can be a block structure. The base 1 can be installed on the tank by fasteners such as bolts. In some other embodiments, the base 1 can also be fixed to the tank by welding, pressure plate fixing, etc. The setting of the base 1 can provide installation points for the installation arrangement of the above-mentioned driver 6, thereby facilitating the installation and fixing of the driver 6.

[0050] The cover assembly 2 is located at the mouth of the can and is used to open and close the mouth of the can. The swinging member 3 is connected to the cover assembly 2. The swinging member 3 is rotatably assembled to the can and is used to drive the cover assembly 2 to open or close the mouth of the can when swinging.

[0051] For example, such as Figure 1As shown, the lid assembly 2 can be a disc-shaped structure. The can opening can be located on the top side of the can. When in use, the lid assembly 2 can be inserted into the can opening to seal it. When the lid assembly 2 is removed from the can opening, it releases the seal.

[0052] It should be noted that each direction in this application can be the corresponding position when the drive device is actually used. The drive device as a whole can be installed on the top side of the tank, with the left side from bottom to top as left, the right side from bottom to top as right, the front side from bottom to top as front, and the rear side from bottom to top as rear.

[0053] The swing component 3 can be a crank structure. The swing component 3 can be pivotally mounted on the can body. One end of the swing component 3 can be directly or indirectly connected to the lid assembly 2. The connection method can be a hinge, pivot, or other rotatable form. This allows the lid assembly 2 to swing freely relative to the swing component 3, enabling it to swing and adjust its own state under the action of gravity. This avoids the lid assembly 2 moving up and down and rotating simultaneously with the swing component 3, thus preventing the lid assembly 2 from being difficult to pull out or insert into the can opening due to swinging, and ensuring the smooth opening and closing of the can opening by the lid assembly 2.

[0054] In use, the swinging member 3 can swing up and down, thereby driving the lid assembly 2 to move up and down, thus fulfilling the functions of sealing and releasing the can opening. Specifically, the front end of the swinging member 3 can be rotatably connected to the lid assembly 2. During the swinging process, the front end of the swinging member 3 can swing up and down. When the front end moves upward, the swinging member 3 can drive the lid assembly 2 to move upward, thereby releasing the seal on the can opening. When the front end moves downward, the swinging member 3 can drive the lid assembly 2 to move downward, thereby allowing the lid assembly 2 to be inserted into the can opening and achieve the sealing of the can opening.

[0055] Multiple steering components 4 are mounted on the tank body and located between the cover assembly 2 and the seat 1, and the multiple steering components 4 include a first steering component 41 arranged adjacent to the seat 1. For example, as Figure 1 As shown, there can be two steering components 4, which can be arranged at intervals in the left and right direction. The steering components 4 can be round shafts, etc., and can be fixed to the tank body 200 by welding or other means. The base 1 can be located on the right side of the two steering components 4, and the steering component 4 located on the right side of the two steering components 4 can be the first steering component 41.

[0056] In some other embodiments, the steering component 4 may also be provided in three, four, or other quantities. The number and specific arrangement position of the steering component 4 can be selectively set according to actual needs.

[0057] The flexible component 5 overlaps with multiple steering components 4 and achieves a change in the extension direction at each steering component 4. The actuator 6 is connected to the base 1, and the flexible component 5 is connected between the swing component 3 and the actuator 6. For example, as Figure 1 As shown, the flexible component 5 can be a structural component with high tensile strength and the ability to bend and deform, such as a steel wire rope. The left end of the flexible component 5 can be connected to the swing component 3, and the right end of the flexible component 5 can be connected to the actuator 6. The flexible component 5 can pass around the two steering components 4 in the left and right directions in sequence.

[0058] The actuator 6 is retractable and is used to pull or release the flexible element 5 during extension or retraction to drive the oscillating element 3 to oscillate. For example, as... Figure 1 As shown, the driver 6 can be a linear drive, the driver 6 can be arranged to extend in the left and right direction, the left end of the driver 6 can be connected to the flexible member 5, and the right end of the driver 6 can be connected to the base 1.

[0059] When the actuator 6 extends, its left end moves to the left, releasing the flexible element 5. Under gravity, the lid assembly 2 falls back to the can opening and seals it. When the actuator 6 retracts, its left end moves to the right, pulling the flexible element 5. The flexible element 5 then drives the swinging element 3 to swing, thus pulling the lid assembly 2 out of the can opening and opening the can.

[0060] The flexible component 5 includes a first flexible segment 51 located between the first steering component 41 and the actuator 6, the extending direction of the first flexible segment 51 being consistent with the extension and retraction direction of the actuator 6. For example, as Figure 1 As shown, the first flexible segment 51 can be the part of the flexible member 5 located between the first steering member 41 and the driver 6, and the extension and retraction directions of the first flexible segment 51 and the driver 6 can both be left and right.

[0061] Therefore, during the extension and retraction of the actuator 6, the force exerted on the actuator 6 by the flexible component 5 is mainly in the left and right direction. That is, the flexible component 5 will not generate a component force perpendicular to the left and right direction applied to the actuator 6, thereby avoiding the situation where the component force can easily damage the actuator 6 and playing a protective role for the actuator 6.

[0062] Secondly, the drive unit 6 and the swing component 3 of the drive device in this application are connected by a steel wire rope and a steering component 4. These components are common parts in the factory, which facilitates maintenance, improves the convenience of operation, and avoids the situation where production is easily delayed due to long maintenance time.

[0063] In some embodiments, the swing member 3 includes a first rod segment 31 and a second rod segment 32. The first rod segment 31 and the second rod segment 32 are connected and arranged at an angle. The connection between the first rod segment 31 and the second rod segment 32 is rotatably assembled with the tank body 200. The second rod segment 32 is arranged adjacent to the flexible member 5 compared to the first rod segment 31. The free end of the first rod segment 31 is connected to the cover assembly 2, and the free end of the second rod segment 32 is connected to the flexible member 5.

[0064] For example, such as Figure 2 As shown, both the first segment 31 and the second segment 32 can be straight rods, and they can be integrally formed by casting. The first segment 31 and the second segment 32 together form a V-shaped structure, with the first segment 31 located to the left of the second segment 32. The top side of the cover assembly 2 can be connected to the first segment 31, and the flexible component 5 can be connected to the second segment 32.

[0065] The connection between the first rod segment 31 and the second rod segment 32 can be rotatably assembled with the tank body 200 via a pivot or the like. In use, the swing member 3 can swing freely around the connection between the first rod segment 31 and the second rod segment 32, and both the first rod segment 31 and the second rod segment 32 can form lever arms. This allows the swing member 3 to be easily driven to swing under the action of the lever arm formed by the first rod segment 31, and also allows the cover assembly 2 to quickly pull the flexible member 5 under the action of gravity, avoiding the situation where the flexible member 5 cannot remain taut, thereby ensuring the structural stability of the assembly of the flexible member 5 and the steering member 4.

[0066] In some embodiments, the swing member 3 is located above the cover assembly 2, and the included angle formed by the first rod segment 31 and the second rod segment 32 is located on the side of the swing member 3 away from the cover assembly 2, and the included angle is an obtuse angle.

[0067] For example, such as Figure 2 As shown, the included angle formed by the first segment 31 and the second segment 32 can be angle α, which can be arranged upwards. The angle of angle α can be 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, etc. This fully meets the usage requirements for driving the cover assembly 2 to move up and down.

[0068] The above-mentioned arrangement of the swing member 3 also allows the first rod segment 31 and the second rod segment 32 to swing above the rotating assembly position of the swing member 3 and the tank body 200 (above the horizontal plane of the rotating assembly), thereby avoiding the situation where the first rod segment 31 and the second rod segment 32 easily interfere with and collide with the cover assembly 2 during swinging, thus improving the convenience and smoothness of operation.

[0069] In some embodiments, the length of the first segment 31 is greater than the length of the second segment 32. For example, as... Figure 2 As shown, the length of the first segment 31 can be regarded as the distance between the free end of the first segment 31 and the connection between the first segment 31 and the second segment 32, and the length of the second segment 32 can be regarded as the distance between the free end of the second segment 32 and the connection between the first segment 31 and the second segment 32.

[0070] The length of the first segment 31 is generally longer than that of the second segment 32. This allows the free end of the first segment 31 to have a larger swing amplitude, thus fully meeting the usage requirements of the drive cover assembly 2. Secondly, the shorter length of the second segment 32 means that the flexible member 5 needs to apply a certain force to drive the swinging member 3, which helps improve the stability of the swinging member 3 driven by the actuator 6.

[0071] In some embodiments, such as Figure 2 As shown, the cover assembly 2 includes a first connector 21, a second connector 22, a cover body 23, and multiple diagonal tie members 24. One end of the first connector 21 is rotatably connected to the first rod segment 31. For example, the first connector 21 can be a rectangular plate structure, and the first connector 21 as a whole can be arranged to extend in the vertical direction. The upset forging of the first connector 21 can be pivotally assembled with the free end of the first rod segment 31.

[0072] The other end of the first connector 21 is rotatably connected to the second connector 22. For example, as Figure 2 As shown, the second connector 22 can be a disc structure, and an ear plate can be provided at the center of the top of the second connector 22. The bottom end of the first connector 21 can be pivotally assembled with the ear plate of the second connector 22.

[0073] Multiple diagonal bracing members 24 are connected between the second connector 22 and the cover 23, and the multiple diagonal bracing members 24 are arranged at intervals along the circumference of the cover 23. For example, as Figure 2 As shown, the diagonal tie 24 can be a chain, and there can be two diagonal tie 24s. The two diagonal tie 24s can be symmetrically arranged on the left and right sides of the second connector 22. The diagonal tie 24 on the left can be arranged at an angle from the lower left to the upper right, and the diagonal tie 24 on the right can be arranged at an angle from the upper left to the lower right.

[0074] The top end of each diagonal brace 24 can be rotatably connected to the second connecting piece 22, and the bottom end of each diagonal brace 24 can be rotatably connected to the top side of the cover 23. This allows for a degree of flexibility in the connection between the cover 23 and the second connecting piece 22, meaning the cover 23 can swing freely relative to the second connecting piece 22. This also creates a lag in force transmission between the cover 23 and the second connecting piece 22, thus providing a certain degree of protection.

[0075] In addition, the symmetrical arrangement of the two diagonal bracing members 24 in the left and right directions helps the cover 23 to quickly achieve balance in the left and right directions. Since the force exerted by the swinging member 3 on the cover assembly 2 is mainly in the left and right directions, the swinging effect of the swinging member 3 on the swinging of the cover 23 can be reduced.

[0076] In some other embodiments, the number of diagonal bracing members 24 may be three, four, five, etc., and multiple diagonal bracing members 24 may be arranged at equal intervals along the circumference of the cover 23.

[0077] In some embodiments, the rotatable connection between the swing member 3 and the tank 200 has a first axis 311, the rotatable connection between the first connector 21 and the first rod segment 31 has a second axis 211, and the rotatable connection between the second connector 22 and the first connector 21 has a third axis 212. The first axis 311, the second axis 211, and the third axis 212 are arranged in parallel and are all orthogonal to the spacing direction of the swing member 3 and the seat 1.

[0078] For example, such as Figure 2 As shown, the first axis 311, the second axis 211, and the third axis 212 can all be arranged to extend in the front-back direction. This allows the first connector 21 and the second connector 22 to swing only in the front-back direction. This satisfies the need for the cover 23 to adaptively adjust its own state according to gravity, and also restricts the swing of the cover 23 in the front-back direction. This makes it easier for the cover 23 to be quickly inserted into the can opening, thus improving the efficiency of operation.

[0079] In some embodiments, the plurality of steering members 4 include a second steering member 42, which is disposed between the oscillating member 3 and the first steering member 41. The second steering member 42 is higher than the first steering member 41. The flexible member 5 also includes a second flexible segment 52 and a third flexible segment 53. The second flexible segment 52 is located between the first steering member 41 and the second steering member 42, and the third flexible segment 53 is located between the second steering member 42 and the oscillating member 3.

[0080] For example, such as Figure 1 and Figure 2As shown, the second steering component 42 can be located between the swing component 3 and the first steering component 41 in the left-right direction, and in the up-down direction, the installation position of the second steering component 42 is higher than the installation position of the first steering component 41.

[0081] The second flexible segment 52 can be the part of the flexible member 5 between the first steering member 41 and the second steering member 42, and the third flexible segment 53 can be the part between the second steering member 42 and the swing member 3. The second flexible segment 52 and the third flexible segment 53 can be V-shaped as a whole, wherein the second flexible segment 52 can be inclined from the upper left to the lower right, and the third flexible segment 53 can be inclined from the lower left to the upper right.

[0082] When the actuator 6 drives the cover 23 to release the seal on the can opening, the extension directions of the third extension section and the second rod section 32 can be kept roughly the same, thereby reducing the influence of the component force and ensuring the structural stability of the cover 23 when it is suspended.

[0083] In some embodiments, such as Figure 1 As shown, the first steering component 41 is located on the upper side of the flexible component 5, and the second steering component 42 is located on the lower side of the flexible component 5. This method of supporting from the top and bottom can improve the structural stability of the flexible component 5 during installation.

[0084] The highest point on the outer periphery of the second steering member 42 is higher than the highest point of the swing trajectory of the free end of the second rod segment 32. For example, the highest point on the outer periphery of the second steering member 42 is the vertex position of the outer periphery of the second steering member 42, and the highest point of the free end of the second rod segment 32 is the highest position that the free end of the second rod segment 32 can reach during the swing.

[0085] The apex of the second steering component 42 is always higher than the highest point of the free end of the second rod segment 32. This satisfies the requirement of suspending and driving the swing component 3 to swing from top to bottom.

[0086] In some embodiments, both the first steering member 41 and the second steering member 42 are pulleys. For example, both the first steering member 41 and the second steering member 42 can be fixed pulleys, which not only meets the arrangement requirements for steering of the flexible member 5, but also reduces the frictional effect of the flexible member 5's movement and traction, thereby improving the smoothness of traction.

[0087] In some embodiments, the driver 6 is rotatably connected to the base 1. For example, as... Figure 1 As shown, the right end of the actuator 6 can be pivotally mounted to the base 1 via a pivot. This allows the actuator 6 to self-adaptively swing in the vertical direction, providing a certain degree of buffering and preventing the rigid connection from being easily damaged by frequent vibrations.

[0088] It should be noted that in actual use, the flexible component 5 can always be kept taut by the gravity of the cover assembly 2, and the driver 6 can also be kept in a horizontal position under the traction of the flexible component 5.

[0089] In some other embodiments, a support structure may also be provided below the driver 6, which can limit the downward swing stroke of the driver 6.

[0090] In some embodiments, the actuator 6 is an electric actuator. This avoids damage and wear to the actuator rod of the hydraulic drive device 100 caused by dust or other contaminants, thereby reducing the overall failure rate.

[0091] The torpedo canister device of this application is described below.

[0092] like Figure 3 As shown, the torpedo canister device of this application includes a canister body 200 and a drive device 100. The drive device 100 can be a torpedo canister cover drive device as described in any of the above embodiments. The base 1, multiple steering components 4, and swing components 3 are all assembled on the canister body 200. For example, there can be two steering components 4, namely a first steering component 41 and a second steering component 42. The base 1, the first steering component 41, and the second steering component 42 can all be fixed to the top side of the canister body 200 by bolts. The swing components 3 can be pivotally mounted on the canister body 200.

[0093] The torpedo canister device of this application has the following beneficial effects:

[0094] 1) Considering the high temperature and dust conditions at the site, the hydraulic transmission (electro-hydraulic actuator) was changed to mechanical transmission (electric actuator), and the power spare part electro-hydraulic actuator was changed to an electric actuator, which improved the stability of the power spare part.

[0095] 2) This transmission structure reduces the vertical component of the electric actuator by decomposing the horizontal tension force through the wire rope, thus protecting the electric actuator more effectively and reducing the failure rate of spare parts.

[0096] 3) The structure adopts wire rope and pulley block. The materials for wire rope and pulley block are common, the cost is relatively low, and spare parts are easy to store.
