Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting and anti-fall-off device for the insulation cover of a torpedo tanker. Background Technology

[0002] In the steel metallurgical industry, torpedo ladle cars are core equipment for transporting molten iron. Their accompanying insulated covers effectively reduce temperature loss during transport, ensuring the temperature requirements of subsequent smelting processes, and are crucial for energy consumption control and production efficiency in steel production. The hoisting operation of the insulated covers is a key link in the turnover of torpedo ladle cars. Currently, the industry generally adopts a traditional hoisting structure of "hook + simple attachment," which involves using a fixed-size hook to attach to the lugs or rings on the top of the insulated cover to achieve lifting, transfer, and closing of the cover.

[0003] Different sizes of torpedo tank cars require insulated covers of different diameters. However, the existing lifting anti-fall devices have fixed hook sizes and attachment positions, which can only accommodate a single size of insulated cover. When it is necessary to replace the insulated cover with a different size, the original lifting anti-fall device must be disassembled and replaced with a hook or lifting frame of the corresponding size. This not only increases the time required for equipment replacement but also requires the stockpiling of multiple sets of lifting anti-fall accessories of different sizes, resulting in a significant increase in equipment costs and inventory pressure.

[0004] Therefore, there is an urgent need for a lifting anti-fall device that can be applied to insulation covers of different sizes, in order to save time in replacing lifting devices, reduce equipment costs, and reduce inventory pressure. Utility Model Content

[0005] Based on the problems of poor size adaptability, the need to replace the lifting device and spend time, and the need to prepare multiple tools and increase inventory pressure in the existing technology, this utility model provides a lifting and anti-drop device for the insulated cover of torpedo tanker. It can use electromagnetic attraction and clamping devices to adapt to insulated covers of different sizes and increase the versatility of the lifting device.

[0006] This utility model relates to a lifting and anti-falling device for the insulation cover of a torpedo tanker, comprising a support column and a lifting ring fixedly installed on the top of the support column, and further comprising: Clamping mechanism: Fixedly installed at the bottom of the support column, used to clamp and limit the position of the insulation cover; Electromagnetic suction: Installed below the support column, it is used to magnetically attract the heat preservation cover and cooperate with the clamping mechanism to achieve a dual anti-fall-off effect.

[0007] In one embodiment, the clamping mechanism is fixedly installed at the bottom of the support column. The clamping mechanism includes a limiting ring, which is umbrella-shaped and limits the edge of the insulation cover. The clamping mechanism also includes an umbrella frame, which is fixedly installed at the bottom of the support column. The limiting ring is fixedly installed at the other end of the umbrella frame away from the support column. A fixing rod is fixedly installed at the bottom of the umbrella frame. Multiple fixing rods are installed in a ring inside the umbrella frame. A sleeve is fixedly installed at the end of the fixing rod away from the umbrella frame. The sleeve serves as the mounting base for the movable parts and provides support for the diameter adjustment of the clamping mechanism.

[0008] In one embodiment, a movable column is fitted inside the sleeve, the movable column can slide up and down relative to the sleeve, and the bottom of the movable column is exposed; an electromagnetic suction is fixedly installed at the bottom of the movable column, and when the movable column slides, it can trigger a change in the diameter of the clamping mechanism to achieve adaptation to the heat preservation cover of different diameters.

[0009] In one embodiment, a vertical rod is fixedly installed on the top of the movable column. The vertical rod extends vertically through the sleeve, and multiple rectangular grooves are axially spaced on the side of the vertical rod. The rectangular grooves are used to cooperate with the positioning component to lock the sliding position of the movable column, thereby fixing the adjusted diameter of the clamping mechanism.

[0010] In one embodiment, a positioning cylinder is fixedly installed on the side of the sleeve, with the axis of the positioning cylinder perpendicular to the axis of the sleeve. A positioning post is movably fitted inside the positioning cylinder, with one end of the positioning post near the vertical rod passing through the sleeve and abutting against the rectangular groove on the vertical rod. A snap-fit ​​groove is provided on the side of the positioning cylinder, and a handle is fixedly installed on the end of the positioning post away from the vertical rod. The end of the handle away from the positioning post extends out of the positioning cylinder through the snap-fit ​​groove. A spring is fixedly installed on the end of the positioning post away from the vertical rod, and the other end of the spring is fixedly installed on the positioning cylinder. The elastic force of the spring can drive the positioning post to automatically snap into the rectangular groove, achieving rapid positioning and locking.

[0011] In one embodiment, a guide rod is movably mounted on the side of the movable column, and the guide rod is rotatable relative to the movable column; a guide groove is formed through the guide rod, and a sliding rod is sleeved in the guide groove, the sliding rod being perpendicular to the guide rod and fixedly mounted to the umbrella frame; when the movable column slides up and down, it drives the guide rod to rotate around the sliding rod as a fulcrum, thereby converting the sliding action into the opening and closing action of the clamping mechanism, realizing diameter adjustment.

[0012] In one embodiment, a plurality of clamping rods are arranged in a ring around the outer side of the limiting ring. Each clamping rod has a moving groove. A sliding frame is fixedly connected to the end of the guide rod away from the movable column. The sliding frame is slidably connected to the moving groove. When the guide rod rotates, the sliding frame slides in the moving groove, thereby pushing the clamping rod to rotate around the fixed point, thus expanding or shrinking the clamping range.

[0013] In one embodiment, the clamping rod is movably mounted on the umbrella frame, and the clamping rod is rotatable relative to the umbrella frame, with the mounting point on the umbrella frame serving as the fulcrum for rotation of the clamping rod.

[0014] In one embodiment, to prevent the clamping mechanism from damaging the tank or the insulation cover, a telescopic rod is elastically connected to the end of the clamping rod away from the support column, and a lever wheel is movably mounted to the end of the telescopic rod away from the clamping rod. The lever wheel can rotate relative to the telescopic rod. The elastic connection between the telescopic rod and the clamping rod prevents the telescopic rod from having a hard collision with the tank or the insulation cover, while the lever wheel can reduce friction with the tank and protect the surface of the equipment.

[0015] The aforementioned anti-fall-off device for lifting insulated covers of torpedo tankers uses a combination design of electromagnetic adsorption and two different clamping mechanisms. The first basic clamping mechanism can prevent fall-off in simple scenarios, while the second adjustable clamping mechanism can adapt to insulated covers of more sizes, effectively increasing the versatility of the lifting device. This comprehensively solves the problems of long replacement time, high equipment cost, and large inventory pressure in existing technologies. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0024] The following is combined Figures 1-6 This paper describes in detail the specific usage process and principle of two clamping mechanisms for the anti-fall-off lifting device for the insulated cover of a torpedo tanker of this utility model.

[0025] like Figure 6 As shown in one embodiment, this embodiment provides a device for preventing the torpedo tanker's insulation cover from falling off during hoisting.

[0026] See Figure 6 The support column 2 has a circular cross-section, the hanging ring 1 is fixedly installed on the top of the support column 2, the umbrella frame 302 is fixedly installed on the bottom of the support column 2, the clamping mechanism 3 is umbrella-shaped, the end of the umbrella frame 302 away from the support column 2 is fixedly installed with a limit ring 301, and the electromagnetic suction 18 is fixedly installed on the bottom of the support column 2, located inside the clamping mechanism 3, and cooperates with the clamping mechanism 3.

[0027] When it is necessary to clamp the insulation cover, the crane lifts the entire lifting device to the top of the insulation cover through the lifting ring 1, and slowly lowers the device so that the electromagnetic suction 18 is close to the top surface of the insulation cover, while the clamping mechanism 3 naturally fits the edge of the insulation cover. When the electromagnetic suction 18 is energized, it generates a magnetic force to firmly attract the heat preservation cover. The clamping mechanism 3 forms a ring-shaped limit from the outside edge of the heat preservation cover to prevent the heat preservation cover from shifting laterally. During the lifting process, the adsorption force of the electromagnetic suction 18 and the limiting force of the clamping mechanism 3 form a double protection, which can prevent the insulation cover from falling off due to the displacement of the adsorption position of the electromagnetic suction 18 or the excessive wind speed in the external environment. This device can be used directly as long as the diameter of the insulation cover is smaller than the diameter of the limiting ring 301, without the need to replace the hoisting device.

[0028] like Figures 1-5 As shown in one embodiment, this embodiment provides a device for preventing the torpedo tanker's insulation cover from falling off during hoisting.

[0029] See Figure 1 , Figure 2 As shown, a lifting ring 1 is fixedly installed at the top of the support column 2. The lifting ring 1 is used to connect with the hook of the crane to realize the hoisting of the entire device. A clamping mechanism 3 is fixedly installed at the bottom of the support column 2. The clamping mechanism 3 is umbrella-shaped and includes an umbrella frame 302 and a limiting ring 301. The umbrella frame 302 is fixedly installed at the bottom of the support column 2, and the limiting ring 301 is fixedly installed at the end of the umbrella frame 302 away from the support column 2. A fixing rod 4 is fixedly installed at the bottom of the umbrella frame 3, and a sleeve 5 is fixedly installed at the bottom of the fixing rod 4. The sleeve 5 provides a sliding channel for the movable column 6.

[0030] See Figure 1 , Figure 3 As shown, a movable column 6 is fitted inside the sleeve 5. The movable column 6 can slide up and down relative to the sleeve 5. An electromagnetic suction 18 is fixedly installed at the bottom of the movable column 6. A guide rod 14 is movably connected to the side of the movable column 6. The guide rod 14 can rotate relative to the movable column 6. The other end of the guide rod 14 is movably connected to the clamping rod 303 through the sliding frame 17.

[0031] See Figure 1 , Figure 3 As shown, the clamping rod 303 is movably mounted on the umbrella frame 3 in the middle. The clamping rod 303 can rotate around the umbrella frame 3. The end of the clamping rod 303 away from the support column 2 is elastically connected to a clamping rod 305. A rotatable rod wheel 306 is movably mounted at the end of the clamping rod 305.

[0032] See Figure 1 , Figure 2 , Figure 4 As shown, a vertical rod 7 is fixedly installed on the top of the movable column 6. The vertical rod 7 passes through the sleeve 5 axially, and rectangular grooves 8 are provided on the side of the vertical rod 7 at intervals.

[0033] See Figure 1 , Figure 2 , Figure 4As shown, the positioning cylinder 9 is fixedly installed on the side of the sleeve 5. The axis of the positioning cylinder 9 is perpendicular to the axis of the sleeve 5. The positioning post 10 is movably sleeved inside the positioning cylinder 9. The end of the positioning post 10 near the vertical rod 7 passes through the sleeve 5 and abuts against the rectangular groove 8 on the vertical rod 7. The side of the positioning cylinder 9 has a snap-fit ​​groove 11. The end of the positioning post 10 away from the vertical rod 7 is fixedly installed with a handle 12. The end of the handle 12 away from the positioning post 10 extends out of the positioning cylinder 9 through the snap-fit ​​groove 11. The spring 13 is fixedly installed on the end of the positioning post 10 away from the vertical rod 7, and the other end of the spring 13 is fixedly installed on the positioning cylinder 9. The elastic force of the spring 13 can drive the positioning post 10 to automatically snap into the rectangular groove 8, realizing quick positioning and locking.

[0034] See Figure 1 , Figure 3 As shown, multiple clamping rods 303 are arranged in a ring around the outer side of the limiting ring 301. A moving groove 304 is provided on each clamping rod 303. A sliding frame 17 is fixedly connected to the end of the guide rod 14 away from the movable column 6. The sliding frame 17 is slidably connected to the moving groove 304.

[0035] See Figure 1 , Figure 3 As shown, the clamping rod 303 is movably mounted on the umbrella frame 3 in the middle, and the clamping rod 303 can rotate relative to the umbrella frame 3.

[0036] See Figure 1 As shown, a clamping rod 305 is elastically and movably connected to the end of the clamping rod 303 away from the support column 2, and a lever wheel 306 is movably installed at the end of the clamping rod 305 away from the clamping rod 303. The lever wheel 306 can rotate relative to the clamping rod 303.

[0037] When it is necessary to lift insulation covers of different diameters, pull the handle 12 and slide it in the snap-fit ​​groove 11 on the positioning cylinder 9 to make the positioning post 10 disengage from the rectangular groove 8 on the vertical rod 7 and release the position lock of the movable post 6.

[0038] The crane lifts the support column 2 through the lifting ring 1. The support column 2 drives the umbrella frame 3 at the bottom to rise synchronously. The umbrella frame 3 drives the sleeve 5 to move upward through the fixing rod 4. Under the action of gravity, the movable column 6 fitted inside the sleeve 5 slides downward.

[0039] The sliding rod 16 is fixedly installed on the umbrella frame 3 and is movably nested in the guide groove 15 on the guide rod 14. When the movable column 6 slides down, it drives the guide rod 14 to rotate counterclockwise around the sliding rod 16 as the fulcrum. The sliding frame 17 is fixedly installed on the end of the guide rod 14 away from the movable column 6 and is movably nested in the moving groove 304 on the clamping rod 303. The counterclockwise rotation of the guide rod 14 will push the clamping rod 303 to rotate counterclockwise around the umbrella frame 3 through the sliding frame 17, making the diameter of the clamping mechanism 23 larger.

[0040] The crane lowers the hoisting device above the insulation cover, so that the electromagnetic suction 18 at the bottom of the movable column 6 presses against the insulation cover. Under the action of gravity, the sleeve 5 slides downward relative to the movable column 6. The movable column 6 drives the guide rod 14 to rotate clockwise around the sliding rod 16 as the fulcrum, which in turn drives the clamping rod 303 to rotate clockwise around the umbrella frame 3, so that the diameter of the clamping mechanism 23 is reduced until the clamping rod 303 abuts against the edge of the insulation cover.

[0041] Pull the handle 12 to slide in the locking groove 11. Under the elastic reset action of the spring 13, the positioning post 10 is locked into the rectangular groove 8 corresponding to the vertical rod 7, so that the movable post 6 is fixed relative to the sleeve 5, thereby keeping the diameter of the clamping mechanism 23 stable and continuously pressing against the edge of the heat preservation cover.

[0042] When the electromagnetic suction 18 is energized, it generates a magnetic force to attract the heat preservation cover. The clamping rod 303 limits the heat preservation cover from the edge to prevent it from tipping over. When the heat preservation cover is hoisted to the mouth of the tank, the elastic connection between the clamping rod 305 and the clamping rod 303 and the rotation characteristics of the rod wheel 306 can prevent the clamping mechanism 23 from having a hard collision or excessive friction with the tank body, thus protecting the surface of the tank body.

[0043] The vertical rod 7 has multiple rectangular slots 8, each corresponding to a specific diameter of the insulation cover. This allows one hoisting device to be used for insulation covers of various diameters, saving time on changing hoisting devices, reducing equipment costs, and minimizing inventory pressure.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
