Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine dummy bar storage technology, specifically to a novel continuous casting machine dummy bar storage device. Background Technology

[0002] The dummy bar is one of the important devices in continuous steel casting. It mainly consists of a dummy bar head, a transition piece, and a bar body. Before casting, the dummy bar head and part of the transition piece need to be placed into the crystallizer to form a movable "inner bottom" of the crystallizer. After casting begins, the molten steel solidifies and solidifies together with the dummy bar head. The dummy bar is pulled by the straightening machine to continuously pull the billet out of the crystallizer.

[0003] Currently, existing dummy bar systems are mainly divided into two categories: chain dummy bars and rigid dummy bar systems. Chain dummy bars are also known as flexible dummy bars. Flexible dummy bars are mainly used in large-scale continuous casting machines for producing billets, such as slabs and large square billets. When storing flexible dummy bars, overhead cranes are often used for hoisting. However, directly using vertical hoisting will occupy a lot of space and has certain requirements on the height of the plant and the installation height of the hoisting equipment. In some plant heights, the flexible dummy bar is too close to the ground when hoisting, which can affect the operating space of other equipment.

[0004] Therefore, there is an urgent need to design a new type of dummy bar storage device for continuous casting machines to solve the problems of complex storage conditions, high storage difficulty, and improper storage affecting the operation of other equipment, thus reducing work efficiency and posing safety hazards. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a new type of continuous casting machine dummy bar storage device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a novel continuous casting machine dummy bar storage device, including an installation plate, an adjustment component and a lifting rod. The installation plate has a two-layer structure, with a connecting plate on the upper layer and a hollow frame-shaped fixing plate on the lower layer. The connecting plate and the fixing plate have the same external dimensions. The adjustment component is located inside the installation plate and is connected to the connecting plate and the fixing plate. A lifting rod is provided below the adjustment component.

[0007] Specifically, the mounting plate is divided into an upper connecting plate and a lower fixing plate, and the top of the connecting plate is provided with four lifting blocks.

[0008] Specifically, the adjustment assembly includes a displacement block, a limiting ring, and a threaded rod. The displacement block is installed at both ends of the fixed plate, and the middle of the displacement block is sleeved on both ends of the threaded rod. A drive shaft is provided on the threaded rod, and a lifting rod is movably connected to the lower part of the displacement block through a bearing. A positioning bolt is provided on the lifting rod, and the limiting ring is sleeved inside the positioning bolt. Both ends of the limiting ring are connected to the displacement block.

[0009] Specifically, the displacement block is divided into a front displacement block, a middle displacement block, and a rear displacement block. The front displacement block is located near both sides of the mounting plate, and the rear displacement block is located near the center of the mounting plate. Each displacement block is equipped with a guide rail. The displacement blocks are fixedly connected as one unit by connecting blocks. An electric push rod is provided between the rear displacement block and the lifting rod.

[0010] Specifically, the drive shaft is located in the middle of the threaded rod, and the drive shaft is equipped with a drive wheel and a motor. There are two drive wheels, which are respectively connected to the threaded rod and the motor, and a belt is wrapped around the drive wheel.

[0011] Specifically, there are four lifting rods, symmetrically distributed on both sides of the mounting plate, and each lifting rod is equipped with a hook pointing towards the center of the mounting plate.

[0012] This utility model has the following beneficial effects:

[0013] This invention relates to a novel continuous casting machine dummy bar storage device. By designing a lifting rod and an electric push rod, the tilt angle of the lifting rod is adjusted to hook and lift the connecting rods at the quarter-thickness of both sides of the dummy bar. This lifting method can greatly save storage space for the dummy bar and avoid affecting other equipment.

[0014] This utility model designs a novel continuous casting machine dummy bar storage device. Through the design of the threaded rod, the position of the lifting rod is adjusted, which facilitates the hook under the lifting rod to quickly connect to the connecting rod on the dummy bar, avoiding the influence of the side plate of the dummy bar and improving the convenience of equipment use. At the same time, this collection method, compared with directly lifting the dummy bar vertically, can distribute the weight of the dummy bar and avoid the deformation of the dummy bar.

[0020] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Example 1:

[0022] like Figures 1-4 As shown, a novel continuous casting machine dummy bar storage device includes a mounting plate 1, an adjusting component 2, and a lifting rod 3. The mounting plate 1 has a two-layer structure, with a connecting plate 1.1 on the upper layer and a hollow frame-type fixing plate 1.2 on the lower layer. The connecting plate 1.1 and the fixing plate 1.2 have the same external dimensions. The adjusting component 2 is located inside the mounting plate 1 and is connected to the connecting plate 1.1 and the fixing plate 1.2. The lifting rod 3 is located below the adjusting component 2.

[0023] Mounting plate 1 is used to install this device. Mounting plate 1 consists of two layers: an upper connecting plate 1.1 and a lower fixing plate 1.2. The connecting plate 1.1 has a lifting block 1.3 on its upper part for connection. The fixing plate 1.2 is used to install the adjustment component 2 and is fixed together with the connecting plate 1.1. The adjustment component 2 includes a displacement block 2.1, a threaded rod 2.4, and a limiting ring 2.3. The displacement block 2.1 is divided into three parts: front, middle, and rear. Each displacement block 2.1 is fitted with a guide rail 2.2. The displacement blocks 2.1 are connected together by connecting blocks and can move within the guide rails 2.2. The threaded rod 2.4 is located in the threaded hole in the middle displacement block 2.1 and is used to adjust the displacement block 2.1 by rotation. The threaded rod 2.4 is equipped with a drive shaft 2.6, which is powered by a motor and conveyed to the drive wheel via a belt. The rotation of the threaded rod 2.4 provides the power for the drive wheel. A limiting ring 2.3 is located below the displacement block 2.1. The two ends of the limiting ring 2.3 are connected to the front and rear displacement blocks 2.1 respectively. The bottom end of the limiting ring 2.3 is mounted on the lifting rod 3 via a pin. The limiting ring 2.3 is used for limiting. An electric push rod 2.5 is provided between the limiting ring 2.3 and the rear displacement block 2.1. The electric push rod 2.5 controls the angle of the lifting rod 3 to facilitate connection with the guide rod. The lifting rod 3 is located below the adjustment assembly 2. The lifting rod 3 is equipped with a hook 3.1. The lifting rod 3 and the hook 3.1 are used to connect the guide rod.

[0024] Example 2: Specific implementation steps using the structural form of Example 1.

[0025] In use, a lifting rope can be connected via the lifting block 1.3. After moving the mounting plate 1 above the derrick, the drive shaft 2.6 drives the drive wheel, which in turn drives the belt, causing the drive wheel to move the center displacement block 2.1. This adjusts the lifting rod 3 to a position close to the middle of the derrick, facilitating the hooking of the connecting rod in the middle of the derrick. Then, the electric push rod 2.518 is activated to rotate the lifting rod 3. By adjusting the height of the mounting plate 1, the hooks 3.1 under the lifting rod 3 hook the connecting rods at the left and right ends of the derrick at the quarter-point. The equipment is then started, causing the hooks 3.1 to move to both ends of the connecting rod in the middle of the derrick, and the equipment is then started to lift and store the derrick.
