Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to a lifting device for transferring refractory bricks after stacking. Background Technology

[0002] After refractory bricks are sintered, they are usually stacked as follows: Figure 1 The structure shown is used for transportation. Its stacking packaging structure consists of a refractory brick stack body 1, which is composed of multiple stacked bricks. An outer cushioning layer is wrapped around the stack body, and the outer side of the cushioning layer is wrapped with a plastic film. A base plate 10 is provided at the lower end of the refractory brick stack body 1, and multiple padding strips 11 are provided at the lower end of the base plate 10. The padding strips 11 are parallel to each other, and the refractory brick stack body 1 is fixed to the base plate 10 by multiple binding straps. The base plate 10 is used to facilitate the stacking operation of the refractory bricks. Generally, forklifts are used for loading, but this method has limitations. Therefore, overhead cranes are also used for loading. During loading, two ropes are looped around the base plate 10 before transfer. However, during the transfer, due to the uncertainty of the rope loop position, the refractory brick stack body 1 is prone to tilting and falling, causing safety accidents. Furthermore, the looping is inconvenient. Utility Model Content

[0003] This utility model provides a lifting device for transferring refractory brick stacks, which solves the shortcomings of the prior art and addresses the safety issues that exist when lifting and transferring refractory brick stacks. It has strong practicality.

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

[0005] A refractory brick stack transfer lifting device includes an upper concave part with a hanging ring welded on it. A crane hook is attached to the hanging ring to facilitate the transfer of the refractory brick stack. Multiple vertical rods are threaded through the upper concave part, with a limiting plate at the upper end of each rod and a lower concave part welded to the lower end. A pair of parallel guide rails are bolted to the lower wall of the lower concave part. Sliding sleeves are fitted at both ends of the guide rails, and a lower plate is bolted to the lower end of each sliding sleeve. A vertical plate is bent at the inner end of the lower plate, and a lifting claw is bent inward at the lower end of the vertical plate. The lifting claw can move inward and lock onto the underside of the bottom plate. This method facilitates the fixing and transfer of the refractory brick stack.

[0006] Furthermore, the hanging ring has a V-shaped structure, which provides strong structural stability and ensures the balance of the entire refractory brick stack during hoisting and transfer.

[0007] Furthermore, reinforcing plates are welded to the outer walls of the bends in the lifting claw and vertical plate to enhance the structural strength of the lifting claw.

[0008] Furthermore, side plates are welded to both sides of the lower plate and the vertical plate to enhance the connection strength between the lower plate and the vertical plate, thereby improving safety during transfer.

[0009] Furthermore, to prevent the lifting claws from moving outwards during transfer and thus improve safety, a pair of oblong holes are provided at both ends of the recessed part. A pull rod passes through these holes, and a horizontal plate is welded to the lower end of the pull rod at the same end. Extending shafts are provided at both ends of the horizontal plate, and a swing plate rotatably mounts on these shafts. A pair of rollers are connected to the inner end of the swing plate via rollers, and the outer circumference of the rollers is tangent to the outer wall of the vertical plate. A rotating seat is hinged to the outer end of the swing plate via an end shaft, and the upper end of the rotating seat is bolted to the end of the guide rail. The upper end of the pull rod is welded... There is a horizontal column with horizontal shafts welded to both ends. An actuating wheel is mounted on the horizontal shaft. A limit nut is threaded to the outer end of the horizontal shaft and is located outside the actuating wheel. Slot holes are opened at both ends of the upper concave part, and the actuating wheel passes through the slot holes. When the upper concave part moves upward due to the upward traction force, it will pull the pull rod upward, thereby causing the inner end of the swing plate to rotate upward. Then, the actuating wheel on the swing plate acts on the outer wall of the vertical plate, thus ensuring the connection effect of the lifting claw to the refractory brick stack and improving the safety during transfer.

[0010] Furthermore, a limiting ring is welded onto the pull rod. The limiting ring is located on the lower side of the concave part. The limiting ring can prevent the pull rod from moving upward a long distance, which would cause the swing plate to rotate excessively, thereby reducing the effect on the vertical plate.

[0011] Furthermore, a top plate is welded to the upper end of the outer wall of the vertical plate, and the lower end of the top plate abuts against the upper wall of the swing plate. The top plate limits the upper wall of the swing plate to prevent the swing plate from rotating excessively.

[0012] The advantages of the above technical solution are:

[0013] This invention ensures safety during the transfer and hoisting of refractory brick stacks and also facilitates connection operations during hoisting. Attached Figure Description

[0018] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0019] like Figures 1-4 As shown, a refractory brick stacking and transfer lifting device includes an upper concave part 2, on which a hanging ring 21 is welded. The hanging ring 21 has a V-shaped structure. Multiple vertical rods 22 are threaded through the upper concave part 2. A limiting plate 23 is provided at the upper end of the vertical rods 22. A lower concave part 24 is welded to the lower end of the vertical rods 22. A pair of parallel guide rails 26 are bolted to the lower wall of the lower concave part 24. Sliding sleeves 27 are respectively fitted at both ends of the guide rails 26. A lower plate 28 is bolted to the lower end of the sliding sleeves 27. A vertical plate 29 is bent at the inner end of the lower plate 28. Side plates 30 are welded to both sides of the lower plate 28 and the vertical plate 29. A lifting claw 31 is bent inward at the lower end of the vertical plate 29. A reinforcing plate 32 is welded to the outer wall of the lifting claw 31 and the bent part of the vertical plate 29.

[0020] In this embodiment, the crane hook is connected to the hanging ring 21, and then the crane is used to transfer the lifting device to the placement location of the refractory brick stack 1. Then the operator moves the lifting claw 31 inward so that the lifting claw 31 is located under the bottom plate 10. After completion, the crane drives the lifting device and the refractory brick stack 1 to move. After moving into the carriage, the lifting claw 31 is moved outward.

[0021] In some embodiments, a pair of oblong holes 25 are respectively opened at both ends of the recessed part 24 of a refractory brick stacking transfer hoist. A pull rod 40 is inserted into the oblong hole 25. A horizontal plate 39 is welded to the lower end of the pull rod 40 located at the same end. An outward shaft 38 is respectively provided at both ends of the horizontal plate 39. A swing plate 35 is rotatably mounted on the outward shaft 38. A pair of rollers 36 are connected to the inner end of the swing plate 35 through rollers. The outer periphery of the rollers 36 is tangent to the outer wall of the vertical plate 29. A rotating seat 33 is hinged to the outer end via an end shaft 34. The upper end of the rotating seat 33 is bolted to the end of the guide rail 26. A horizontal column 42 is welded to the upper end of the pull rod 40. Horizontal shafts 43 are welded to both ends of the horizontal column 42. An actuating wheel 44 is rotatably mounted on the horizontal shaft 43. A limit nut is threaded to the outer end of the horizontal shaft 43. The limit nut is located outside the actuating wheel 44. Slot holes 20 are respectively opened at both ends of the upper concave part 2, and the actuating wheel 44 passes through the slot holes 20. A limit ring 41 is welded to the pull rod 40, and the limit ring 41 is located below the lower concave part 24. A top plate 37 is welded to the upper end of the outer wall of the vertical plate 29, and the lower end of the top plate 37 abuts against the upper wall of the swing plate 35.

[0022] In this embodiment, when the lifting claw 31 is located on the lower side of the base plate 10, and then the trolley pulls the upper concave part 2 upward, the upper concave part 2 will first move upward along the length direction of the vertical rod 22, and during the movement, it will drive the horizontal column 42, the pull rod 40 and the horizontal plate 30 to move upward. When the above components move upward, the inner end of the swing plate 35 will swing upward. During the swing, the roller 36 will push the vertical plate 29 to move inward until the upper end of the swing plate 35 contacts the lower wall of the top plate 37, and the limiting ring 41 contacts the lower side of the lower concave part 24. After that, the refractory brick stack 1 will be transferred by the trolley, thus ensuring safety during the transfer.
