Description

Technical Field

[0001] This application relates to the field of steelmaking equipment technology, and in particular to a stopper rod placement and transport device. Background Technology

[0002] A stopper rod is a refractory material rod installed inside a steel ladle, controlling the opening and closing of the nozzle and the flow rate of molten steel through its lifting and displacement. It is also known as a ceramic stopper rod. It consists of a core, sleeve bricks, and a stopper head brick. The core is typically made of plain carbon steel round bars with a diameter of 30–60 mm.

[0003] The utility model patent with announcement number CN218080389U discloses a stopper rod mechanism, including a mounting box and a stopper rod. A closing door is movably installed at the front end of the mounting box, and a movable box is fixedly installed at the top of the mounting box. A stopper rod extending into the mounting box is movably installed inside the movable box. A lifting cross arm is installed on the stopper rod, and the stopper rod body is screwed onto the bottom of the lifting cross arm through a threaded sleeve.

[0004] The stopper rod is cylindrical. Ordinary stopper rods have no protrusions or depressions on their outer walls. After the stopper rods are manufactured, they are usually placed horizontally and transported by stacking. A buffer material layer is placed between adjacent stopper rods to prevent wear.

[0005] Regarding the aforementioned technologies, the inventors believe that after the stopper rod is installed, it is in a vertical position, which requires the horizontally placed stopper rod to be erected. This process is completed by hoisting equipment and manual assistance. Because the stopper rod is heavy and has a large inertia, it swings during the process of rotating to a vertical position, and the bottom of the stopper rod will also be displaced. The stopper rod is prone to colliding with foreign objects or being worn, which needs to be improved. Utility Model Content

[0006] This application provides a stopper rod placement and transportation device, in which the stopper rod is placed vertically inside the device, which can effectively limit and protect the stopper rod, and facilitate the subsequent hoisting and installation of the stopper rod.

[0007] This application provides a stopper rod placement and transportation device, which adopts the following technical solution: A stopper rod placement and transport device includes a housing and multiple partitions, with adjacent partitions for the entry of stopper rods. The front and rear side walls of the housing are provided with horizontally arranged sliding grooves. Both ends of each partition are fixed with screws, which are slidably disposed within the sliding grooves. The ends of the screws located outside the sliding grooves are threaded with nuts. Multiple left-right extending partitions are fixed in the middle of the housing, with adjacent partitions for the entry of stopper rods.

[0008] By adopting the above technical solution, the stopper rod is placed vertically inside the housing. After the stopper rod is placed between adjacent partitions, the two opposing clamping plates clamp the stopper rod by sliding the partitions. Then, the nut is rotated to lock the position of the partitions. Through the cooperation of the first partition, displacement of the stopper rod is prevented. When it is necessary to remove the stopper rod, the partition is moved to loosen the stopper rod. The stopper rod is still confined between the adjacent partition and the adjacent first partition, so the stopper rod will not tip over, facilitating subsequent hoisting.

[0009] Optionally, a slider is fixed to the end of the spacer near the screw, and a guide groove is provided on the inner wall of the housing, with the slider slidably connected to the guide groove.

[0010] By adopting the above technical solution, the stability of the partition sliding is improved through the cooperation between the slider and the guide groove.

[0011] Optionally, a screwdriver is fixed to the nut.

[0012] By adopting the above technical solution, the screwdriver allows personnel to easily rotate the nut by hand, making it more convenient to use.

[0013] Optionally, multiple front-to-back extending partitions are fixed in the middle of the housing, and the space between adjacent partitions is used for the insertion of a stopper rod.

[0014] By adopting the above technical solution and by setting up the second partition, even if the upper part of the stopper rod loses the limiting effect of the partition, the stopper rod will not tip over.

[0015] Optionally, the first partition and the second partition are perpendicular to each other, the distance between adjacent first partitions is greater than the diameter of the stopper rod, and the distance between adjacent second partitions is also greater than the diameter of the stopper rod.

[0016] By adopting the above technical solution, partition one and partition two form a rectangular grid structure. The stopper rod can sway slightly within the grid formed by partition one and partition two, but will not tip over, which facilitates the hoisting of the stopper rod.

[0017] Optionally, a rubber layer is fixed to the surface of the first partition and the second partition.

[0018] By adopting the above technical solution, the rubber layer plays a buffering role, preventing the contact between the first and second partitions from damaging the outer surface of the stopper rod.

[0019] Optionally, a rubber clamp is fixed to one side of each adjacent spacer facing each other, and an arc-shaped groove is provided on the side of the clamp away from the spacer.

[0020] By adopting the above technical solution, the clamping plate contacts the outer wall of the stopper rod through the arc groove, which improves the stability of clamping the stopper rod, and the rubber clamping plate will not damage the stopper rod.

[0021] Optionally, a rubber base plate is fixed to the inner bottom wall of the box, and a groove is provided on the base plate corresponding to the position of the stopper rod.

[0022] By adopting the above technical solution, the bottom end of the stopper rod is contacted by a rubber base plate to avoid wear on the bottom end of the stopper rod, and the bottom end of the stopper rod is limited by a groove to prevent the bottom end of the stopper rod from moving, thereby improving the stability of placement.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. It can ensure the stability of the stopper rod position during transportation and avoid collision and wear on the outer wall of the stopper rod; 2. The stopper rod is stored in a vertical position to avoid flipping during installation, thus preventing the stopper rod from swinging or shifting during hoisting, making it safer and preventing the surface of the stopper rod from being worn. 3. The stopper rod will not tip over inside the housing, making it easy to hoist the stopper rod in and out of the housing. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 This embodiment discloses a stopper rod placement and transportation device, including a box body 1 and multiple partitions 2. The length direction of the partitions 2 is along the front-rear direction of the box body 1. The space between adjacent partitions 2 is used for the stopper rod to enter. The partitions 2 are located at the top of the box body 1 and are used to limit the upper sides of the side wall of the stopper rod.

[0028] Multiple left-right extending partitions 31 are fixed in the middle of the housing 1. The space between adjacent partitions 31 is used for the insertion of the stopper rod. In a top view, the length direction of the partition 31 is perpendicular to the partition 2. The partition 2 prevents the stopper rod from tilting in the left-right direction, and the partition 31 prevents the stopper rod from tilting in the front-back direction. Therefore, the combination of the partition 2 and the partition 31 can prevent the stopper rod from tipping over.

[0029] Multiple front-to-back extending partitions 32 are fixed in the middle of the housing 1, with space between adjacent partitions 32 for the insertion of a stopper rod. Partitions 31 and 32 are perpendicular to each other, forming a rectangular grid structure, with one stopper rod passing through each grid. It should be noted that the distance between adjacent partitions 31 is greater than the diameter of the stopper rod, and the distance between adjacent partitions 32 is also greater than the diameter of the stopper rod. This means the stopper rod can sway slightly within the grid formed by partitions 31 and 32, but will not tip over. By using partitions 32, even if the upper part of the stopper rod loses the limiting effect of partition 2, the stopper rod will not tip over. A rubber layer is fixed to the surface of partitions 31 and 32, which acts as a buffer to prevent damage to the outer surface of the stopper rod from contact with partitions 31 and 32.

[0030] A rubber base plate 4 is fixed to the inner bottom wall of the housing 1. A groove 41 is provided on the base plate 4 corresponding to the position of the stopper rod. The rubber base plate 4 contacts the bottom end of the stopper rod to prevent wear on the bottom end of the stopper rod. The bottom end of the stopper rod is inserted into the groove 41, which limits the bottom end of the stopper rod to prevent it from moving and improves the stability of the placement.

[0031] Spacer 2 can slide left and right, and its specific structure is as follows: (Refer to...) Figure 1 and Figure 2 The front and rear side walls of the housing 1 are provided with horizontally arranged sliding grooves 11. Screws 21 are fixed to both ends of the partition 2, and the screws 21 are slidably disposed within the sliding grooves 11. A nut 5 is threadedly connected to the end of the screw 21 outside the sliding grooves 11, and a locking plate 51 is fixed to the nut 5. The locking plate 51 allows personnel to manually rotate the nut 5. Tightening the nut 5 presses it against the outer side wall of the housing 1, thus locking the position of the partition 2. Loosening the nut 5 allows the screw 21 to slide along the sliding grooves 11, thereby moving the partition 2 left and right.

[0032] Reference Figure 3 A slider 22 is fixed to the end of the spacer 2 near the screw 21. A guide groove 12 is provided on the inner wall of the housing 1, and the slider 22 is slidably connected to the guide groove 12. The slider 22 is a rectangular block, and the screw 21 passes through the slider 22 and is fixed to the slider 22. The cooperation between the slider 22 and the guide groove 12 improves the sliding stability of the spacer 2 and prevents the spacer 2 from rotating.

[0033] Reference Figure 1 A rubber clamp 23 is fixed on the side of the adjacent spacer 2 facing each other. An arc groove 24 is opened on the side of the clamp 23 away from the spacer 2. The clamp 23 contacts the outer wall of the stopper rod through the arc groove 24.

[0034] The implementation principle of a stopper rod placement and transportation device according to an embodiment of this application is as follows: the stopper rod is placed vertically inside the box 1. After the stopper rod is placed between adjacent partitions 2, the two opposing clamping plates 23 are clamped by sliding the partitions 2. Then, the position of the partitions 2 is locked by rotating the nut 5, which can prevent the stopper rod from shifting. After all the stopper rods are locked, the box 1 can be transported. During the transportation process, the stability of the stopper rod position can be guaranteed, and collision and wear on the outer wall of the stopper rod can be avoided.

[0035] When it is necessary to remove the stopper rod, loosen the nut 5, and the sliding spacer 2 will release the clamping state of the stopper rod. At this time, the stopper rod is still limited between the adjacent spacer 2 and the adjacent partition 31, so the stopper rod will not tip over. Then, use hoisting equipment to lift the stopper rod out of the housing 1 for installation.

[0036] By using this stopper rod placement and transportation device, the stopper rod is stored in a vertical position, avoiding the stopper rod from flipping during installation. Therefore, it can prevent the stopper rod from swinging or shifting during hoisting, making it safer and preventing the surface of the stopper rod from being worn.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
