Description

Technical Field

[0001] This utility model relates to the field of electroslag ingot transfer technology, and in particular to a hollow electroslag ingot horizontal lifting device. Background Technology

[0002] Electroslag ingots are columnar billets produced through secondary refining, exhibiting a columnar structure, some with a central hole. These ingots are typically transferred using vertical lifting equipment. In actual production, some ingots lie flat, posing a challenge for transfer. Ingots with a central hole are relatively easier to transfer; for example, an operator inserts a steel cable through the hole, with a hanging ring at each end, and the crane hook is attached to the rings. However, threading the steel cable is difficult, and prolonged use can cause wear and significant deformation of the cable due to the edges of the central hole, increasing safety risks. Furthermore, significant cable deformation makes inserting the cable through the central hole even more difficult. Utility Model Content

[0003] This utility model provides a horizontal lifting device for hollow electroslag ingots to overcome the shortcomings of the prior art, solve the problems of inconvenient operation and safety hazards during the transfer of hollow electroslag ingots, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A hollow electroslag ingot horizontal lifting device includes a concave part with a lifting lug fixed at the middle position along its length. The lifting lug is connected to a hook on a crane. Long slots are opened on both sides of the two ends of the concave part, and waist-shaped holes are opened at the bottom of both ends of the concave part. A horizontal bar is movably installed in the long slots. Concave fasteners are fitted on both ends of the horizontal bar. Locking nuts are threaded to both ends of the horizontal bar. The inner end of the locking nut is pressed against both sides of the concave fastener. The locking nut can lock the position of the concave fastener to prevent the electroslag ingot from moving back and forth along the length of the concave part when transferring the electroslag ingot. A vertical rod is threaded through a concave fastener, with its upper end passing through a slotted hole. A limiting nut is located at the upper end of the vertical rod, positioned on the upper side of the concave fastener. A concave head is welded to the lower end of one vertical rod, and a connecting rod passes through the lower end of the concave head. An inner extension rod is rotatably mounted on the connecting rod. A horizontal plate is welded to the lower end of the other vertical rod, with one end of the horizontal plate vertically forming a vertical plate. The lower end of the vertical plate is bent into an arc plate, and the inner extension rod is located within the arc plate. The inner extension rod passes through the central hole of the electroslag ingot, with its other end resting on the arc plate. Compared to existing technologies, this solution replaces the steel cable with an inner extension rod, which offers the advantage of convenient installation. Furthermore, this solution allows for the transfer of hollow electroslag ingots of different lengths by adjusting the distance between the two vertical rods, thus expanding its applicability.

[0005] Furthermore, the lugs have a V-shaped structure.

[0006] Furthermore, a pair of strip-shaped holes are provided on the outer end of the horizontal plate, and a moving rod is movably installed within the strip-shaped holes. An upper moving plate is provided at the upper end of the moving rod, which is located on the upper side of the horizontal plate. A T-shaped seat is threadedly connected to the upper end of the moving rod, which is located on the lower side of the horizontal plate. An upper rotating seat is rotatably installed at the lower end of the T-shaped seat via a connecting shaft. A pair of pull rods are threadedly connected to the lower end of the upper rotating seat, and a lower top plate is provided at the lower end of the pull rods. An outward protrusion is bent at the other end of the arc plate, and a pair of U-shaped grooves are provided on the outward protrusion. The pull rods pass through the U-shaped grooves. The lower top plate is located on the lower side of the outward protrusion. The upper rotating seat plays a role in shielding the opening space between the outward protrusion and the horizontal plate. While improving the connection strength between the outward protrusion and the horizontal plate, it also prevents the inner through rod from moving outward from between the outward protrusion and the horizontal plate, thus avoiding safety issues.

[0007] Furthermore, a limiting block is welded to the lower wall of the outward-extending convex plate. The limiting block is located on the outside of the lower top plate and plays a limiting role in the lower top plate, preventing the lower top plate from moving outward and losing its limiting function for the inward-extending through rod.

[0008] Furthermore, the two ends of the connecting shaft are axially limited by cotter pins or nuts, thereby improving the stability of the connecting shaft after connection.

[0009] The advantages of the above technical solution are: This invention replaces the existing steel cable with an inner extension rod, which improves safety and facilitates the installation process. Attached Figure Description

[0013] Figure 3 A magnified view of point A is shown. Detailed Implementation

[0014] like Figures 1-3As shown, a hollow electroslag ingot horizontal lifting device includes a concave part 1. A lifting lug 10 is fixed at the middle position along the length of the concave part 1. The lifting lug 10 has a V-shaped structure. Long strip holes 11 are opened on both sides of the two ends of the concave part 1. Waist-shaped holes 12 are opened at the bottom of both ends of the concave part 1. A horizontal bar 2 is movably installed in the long strip holes 11. Concave fasteners 20 are sleeved on both ends of the horizontal bar 2. A vertical bar 21 is passed through the concave fasteners 20. The upper end of the vertical bar 21 passes through the waist-shaped hole 12. A limiting nut 22 is provided at the upper end of the vertical bar 21. The limiting nut 22 is located on the upper side of the concave part 1.

[0015] One of the vertical rods 21 has a concave head 3 welded to its lower end, and a connecting rod 30 is inserted through the lower end of the concave head 3. An inner extension rod 31 is rotatably provided on the connecting rod 30.

[0016] Another vertical rod 21 has a horizontal plate 32 welded to its lower end. One end of the horizontal plate 32 is vertically formed into a vertical plate 33. The lower end of the vertical plate 33 is bent into an arc plate 34. The inner through rod 31 is located inside the arc plate 34.

[0017] A pair of strip-shaped holes 37 are provided on the outer end of the horizontal plate 32. A moving rod 38 is movable within the strip-shaped holes 37. An upper moving plate 39 is provided at the upper end of the moving rod 38. The upper moving plate 39 is located on the upper side of the horizontal plate 32. A T-shaped seat 40 is threadedly connected to the upper end of the moving rod 38. The T-shaped seat 40 is located on the lower side of the horizontal plate 32. An upper rotating seat 42 is rotatably provided at the lower end of the T-shaped seat 40 via a connecting shaft 41. A pair of pull rods 43 are threadedly connected to the lower end of the upper rotating seat 42. A lower top plate 44 is provided at the lower end of the pull rods 43. An outward protruding plate 35 is bent at the other end of the arc plate 34. A pair of U-shaped grooves 36 are provided on the outward protruding plate 35. The pull rods 43 pass through the U-shaped grooves 36. The lower top plate 44 is located on the lower side of the outward protruding plate 35. A limit block is welded to the lower wall of the outward protruding plate 35. The limit block is located on the outer side of the lower top plate 44. The two ends of the connecting shaft 41 are axially limited by cotter pins or nuts.

[0018] In this embodiment, during operation, the operator first adjusts the distance between the two vertical rods 21 according to the length of the electroslag ingot. During the adjustment process, it is necessary to ensure that the vertical rods 21 move equal distances so that the lifting lug 10 is always located at the midpoint of the line connecting the vertical rods 21, so as to avoid the problem of tilting and moving when the electroslag ingot is not directly below the lifting lug 10 during hoisting by the crane.

[0019] Then, the operator inserts the inner extension rod 31 into the central hole of the electroslag ingot. During insertion, the inner extension rod 31 can be rotated so that the concave part 1 is located at one end of the electroslag ingot. After insertion, the operator rotates the concave part 1 around the axis of the connecting rod 30 so that it is located above the electroslag ingot. During the movement, the vertical rod 21 where the horizontal plate 32 is located can be moved outward first. After the rotation is completed, the inner extension rod 31 is first inserted into the arc plate 34, and then the vertical rod 21 is moved inward so that it is equal to the distance between the vertical rod 21 and the lifting lug 10. Then, the electroslag ingot is transferred by the crane.

[0020] In another implementation, the operator can rotate the concave part 1 around the vertical rod 21. After the inner through rod 31 is inserted, the concave part 1 can be rotated inward so that the inner through rod 31 passes between the outer protruding plate 35 and the horizontal plate 32. Then, the upper rotating seat 42 is rotated downward. During the rotation, the pull rod 43 is inserted into the U-shaped groove 36, and the lower top plate 44 is located inside the limiting block and below the outer protruding plate 35. Then, the upper wall of the lower top plate 44 and the lower wall of the outer protruding plate 35 are abutted by screwing the pull rod 43.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
