Description

Technical Field

[0001] This utility model relates to the field of electroslag ingot transfer technology, and in particular to a vertical lifting clamp for electroslag ingots. Background Technology

[0002] Electroslag ingots are columnar structures produced through secondary refining. To ensure safety during transfer, they are often transported vertically. During the transfer, a clamp connected to a crane is moved to the top of the electroslag ingot, and then the clamp wraps around the ingot. Subsequently, the clamp is lifted to hold the top of the ingot. This holding method relies on the frictional force generated by the force exerted by the clamp on the outer periphery of the electroslag ingot to hold it during the lifting and transfer. However, this transfer method has the problem of poor safety. Utility Model Content

[0003] This utility model provides a vertical lifting clamp for electroslag ingots to overcome the shortcomings of the prior art and solve the problem of low safety during the transfer of electroslag ingots, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A vertical lifting clamp for electroslag ingots includes a tray. Multiple protruding plates are formed on the outer periphery of the tray. A pair of strip-shaped holes are formed on each protruding plate, with the length direction of the holes parallel to the length direction of the protruding plates. A moving rod is movably mounted within each strip-shaped hole. A lower moving plate is located at the lower end of the moving rod, below the protruding plates. An upper moving plate is located at the upper end of the moving rod, above the protruding plates. A limiting upper plate is formed on the inner side of the upper moving plate, with a pair of grooves formed on it. A lower end plate is located at the lower side of the limiting upper plate, above the protruding plates. A [missing information - likely a component or material] is welded to the lower end plate. For the vertical plate, a pair of vertical holes are opened at the lower end of the vertical plate. A through rod is moved in the vertical holes. The vertical plate is inserted into the groove. An L-shaped arm is provided on the through rod. Multiple pull rods are provided on the vertical section of the L-shaped arm. A lifting plate is fixed to the upper end of the vertical section of the L-shaped arm by bolts. A lifting ring is welded on the lifting plate. A connecting shaft is provided on the vertical plate. A pair of swing arms are rotatably provided on the connecting shaft. A waist-shaped hole is opened at the outer end of the swing arm. The pull rod is inserted into the waist-shaped hole. An inner shaft is connected to the inner end of each pair of swing arms. An inner top bar is rotatably provided on the inner shaft. An inner top plate is welded to the inner wall of the inner top bar.

[0006] Furthermore, the lower wall of the tray is bolted with multiple concave supports.

[0007] Furthermore, a clamping plate is fixed to the inner wall of the inner top plate by bolts, and clamping teeth are provided on the inner wall of the clamping plate.

[0008] Furthermore, the outer end of the convex plate is provided with an end pin, and an inner top rotating plate is rotatably provided on the end pin. The inner end of the inner top rotating plate abuts against the outer wall of the lower moving plate, and the end pin is axially limited by a cotter pin or nut.

[0009] Furthermore, the lower end of the moving rod is axially limited by a nut threaded onto it.

[0010] Furthermore, the two ends of the through rod, tie rod, connecting shaft, and inner shaft are respectively limited axially by setting cotter pins or nuts.

[0011] The advantages of the above technical solution are:

[0012] This invention uses a pallet to support the lower end of the electroslag ingot, which plays a supporting role during hoisting and transfer, thus improving the safety of the transfer compared to existing technologies.

[0013] This invention utilizes a movable limiting upper plate, which, when moved inward, limits the upper end of the lower plate, thereby connecting the inner top plate and its connected components to a tray. This method facilitates the transfer of electroslag ingots onto the tray, as there are no obstructions above the tray during the transfer process, making it easy to place the ingots. Secondly, to ensure the limiting effect of the upper plate, an inner top rotating plate is also provided. When its length direction is parallel to the length direction of the protruding plate, it prevents the upper plate from moving outward.

[0014] During the hoisting process, this invention enables the lifting plate to move upwards, and as the lifting plate moves, each L-shaped arm moves upwards. During this movement, the pull rod on it acts on the waist-shaped hole, causing the inner end of the swing arm to rotate downwards. This causes the clamping teeth on the clamping plate to act on the outer periphery of the electroslag ingot, thereby constraining the outer periphery of the electroslag ingot and improving the safety of the electroslag ingot transfer.

[0019] Figure 4A magnified view of point B is shown. Detailed Implementation

[0020] like Figures 1-4 As shown, a vertical lifting clamp for electroslag ingots includes a tray 1. Multiple concave supports 10 are bolted to the lower wall of the tray 1. Multiple protruding plates 11 are formed on the outer periphery of the tray 1. A pair of strip-shaped holes 12 are formed on each protruding plate 11, with the length direction of the strip-shaped holes 12 parallel to the length direction of the protruding plate 11. A moving rod 21 is movably mounted within the strip-shaped holes 12. The lower end of the moving rod 21 is axially limited by a nut threaded onto it. A lower moving plate 22 is provided at the lower end of the moving rod 21, located below the protruding plate 11. An upper moving plate 23 is provided at the upper end of the moving rod 21, located above the protruding plate 11. A limiting upper plate 231 is formed on the inner side of the upper moving plate 23, with a pair of grooves formed on the limiting upper plate 231. A lower end plate 230 is provided on the lower side of the limiting upper plate 231, located above the protruding plate 11. A pair of vertical plates 24 are welded onto plate 230. A pair of vertical holes 25 are formed at the lower end of each vertical plate 24. A through rod 26 moves within each vertical hole 25, through which the vertical plates 24 pass. An L-shaped arm 27 is mounted on the through rod 26. Multiple pull rods 28 are mounted on the vertical section of the L-shaped arm 27. A lifting plate 36 is bolted to the upper end of the vertical section of the L-shaped arm 27. A lifting ring 37 is welded onto the lifting plate 36. A connecting shaft is mounted on the vertical plate 24. 29. A pair of swing arms 30 are rotatably mounted on the connecting shaft 29. The outer end of the swing arm 30 is provided with a waist-shaped hole 31. The pull rod 28 passes through the waist-shaped hole 31. The inner end of each pair of swing arms 30 is connected to an inner shaft 32. An inner top bar 33 is rotatably mounted on the inner shaft 32. An inner top plate 34 is welded to the inner wall of the inner top bar 33. A clamping plate 35 is fixed to the inner wall of the inner top plate 34 by bolts. Clamping teeth are provided on the inner wall of the clamping plate 35.

[0021] The outer end of the protruding plate 11 is provided with an end pin 2, and an inner top rotating plate 20 is rotatably provided on the end pin 2. The inner end of the inner top rotating plate 20 abuts against the outer wall of the lower moving plate 22. The end pin 2 is axially limited by a cotter pin or nut.

[0022] The two ends of the aforementioned through rod 26, pull rod 28, connecting shaft 29 and inner shaft 32 are respectively limited axially by setting cotter pins or nuts.

[0023] In this embodiment, the electroslag ingot is first transferred to the tray 1, and during the transfer and placement, the electroslag ingot and the tray 1 should be made as coaxial as possible.

[0024] Then, the lifting plate 36 and other components are transferred to the tray 1 by a crane, so that each lower end plate 230 is located at the protrusion plate 11.

[0025] Then the operator rotates the inner top rotating plate 20 so that it pushes the lower moving plate 22 and the upper limiting plate 231 inward along the length of the strip hole 12, and so that the upper limiting plate 231 is above the lower end plate 230.

[0026] Then, the hoisting rope on the gantry crane pulls the lifting plate 36 upward. During the movement, the L-shaped arm 27 will move upward in the vertical direction. During the movement, the pull rod 28 will act on the waist-shaped hole 31, which will cause the inner end of the swing arm 30 to rotate downward around the axis of the connecting shaft 29. During the rotation, the clamping plate 35 will move inward, and the clamping teeth on its inner wall will abut against the electroslag ingot. When the gantry crane continues to pull the hoisting rope, the electroslag ingot will move upward with the tray 1 and be transferred to the designated location.
