Description

Technical Field

[0001] This utility model relates to the field of lifting hook technology, specifically a lifting hook for a heating furnace. Background Technology

[0002] Hooks are key components in lifting equipment used for suspending and moving heavy objects, and are widely used in construction, manufacturing, logistics and other fields.

[0003] In industrial production, especially in metallurgy, forging, and heat treatment, workpieces often need to be hoisted into heating furnaces for high-temperature processing. Traditional hoisting methods involve manually operating a hook to suspend the workpiece before placing it into the heating furnace.

[0004] Because the temperature near the heating furnace is extremely high, workers need to be close to the furnace opening when manually hooking or unhooking, which poses risks such as burns and heat radiation damage. Manual operation relies on workers' experience, the hoisting speed is slow, it affects the production cycle, and it is difficult to adapt to the needs of automated production. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting hook for a heating furnace to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hook for a heating furnace, comprising a U-shaped frame, wherein the surface of the U-shaped frame is provided with a gripping component and a limiting component;

[0007] The crawling component includes:

[0008] Through holes are used to stabilize the movement of the I-beam frame;

[0009] The I-beam frame is used to drive the movable plate to rotate.

[0010] Hooks are used for hoisting hot furnaces.

[0011] Preferably, the through hole is formed on the surface of the U-shaped frame, and an I-shaped frame is slidably connected to the inner wall of the through hole. A fixed frame is fixed to the top of the I-shaped frame, and a connecting shaft is fixed to the inner side of the fixed frame. A movable plate is hinged to the bottom of the I-shaped frame, and a hook is hinged to the bottom of the movable plate. When the hook touches the ground, the connecting shaft and the fixed frame drive the I-shaped frame to move down synchronously. The movable plate drives the hooks to move away from each other, and the lifting device moves up. The movable plate brings the hooks closer together for hanging.

[0012] Preferably, the limiting component includes a sliding groove, which is formed at both ends of the I-shaped frame. A locking block is slidably connected to the inner wall of the sliding groove. A spring is fixed to one end of the locking block near the inner wall of the sliding groove, and the end of the spring away from the locking block is fixed to the inner wall of the sliding groove. Fixing blocks are fixed to both sides of the U-shaped frame, and sliding blocks are slidably connected to both sides of the U-shaped frame. Magnets are fixed to both sides of the U-shaped frame, and the magnets are magnetically connected to the sliding blocks. The side of the locking block away from the inclined plane abuts against the side of the fixing block away from the inclined plane, thereby limiting the I-shaped frame. When the locking block is below the sliding block, the connecting shaft, fixing frame, and I-shaped frame are pulled upward by the hoisting device. When the sliding block and the surface of the fixing block are in contact, the locking block moves along the surface of the sliding block to the surface of the fixing block, releasing the limiting.

[0013] Preferably, the movable plate is provided in two sets, and both sets of movable plates are symmetrically arranged with the center line of the U-shaped frame as the axis of symmetry, so that the hooks can move closer or further away from each other synchronously.

[0014] Preferably, the bottom of the end of the locking block away from the spring is set as an inclined surface, which allows the locking block to move into the slide groove when it is pressed, thus avoiding affecting the limiting position.

[0015] Preferably, the ends of the fixed block and the sliding block that are far apart from each other are set as inclined surfaces. When they are in contact, the locking block can move along the surfaces of the sliding block and the fixed block, which facilitates the release of the limit.

[0016] Compared with the prior art, the present invention provides a hook for a heating furnace, which has the following advantages:

[0017] 1. The lifting hook of this heating furnace, through the set gripping component, connects with the connecting shaft through the lifting device during hoisting, so that the hook touches the ground. The connecting shaft and the fixed frame drive the I-shaped frame to move down synchronously. The movable plate flips, which can move the hooks away from each other and put them in the open state. At this time, the hooks can be moved above the workpiece through the lifting device. When the lifting device moves up, the movable plate makes the hooks come closer together for hanging. No manual hoisting is required, avoiding danger.

[0018] 2. The lifting hook of this heating furnace has a limiting component. When the hook is in the open state, the locking block and the fixing block limit each other, which facilitates the hanging of workpieces. When lifting the workpiece, the limiting can be released by the mutual contact of the sliding block and the fixing block, which prevents the hook from moving close to each other and resetting, and the workpiece can be lifted and moved, thus improving the stability of the hook.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a hook for a heating furnace, including a U-shaped frame 1, the surface of which is provided with a gripping component 2 and a limiting component 3; the gripping component 2 includes: a through hole 20, an I-shaped frame 21, a fixing frame 22, a connecting shaft 23, a movable plate 24, and a hook 25.

[0025] A through hole 20 is formed on the surface of the U-shaped frame 1. An I-shaped frame 21 is slidably connected to the inner wall of the through hole 20. A fixed frame 22 is fixed to the top of the I-shaped frame 21. A connecting shaft 23 is fixed to the inner side of the fixed frame 22. A movable plate 24 is hinged to the bottom of the I-shaped frame 21. A hook 25 is hinged to the bottom of the movable plate 24. Two sets of movable plates 24 are provided, and the two sets of movable plates 24 are symmetrically arranged with the center line of the U-shaped frame 1 as the axis of symmetry. When hoisting, the hook 25 touches the ground. At this time, the connecting shaft 23 and the fixed frame 22 drive the I-shaped frame 21 to move down synchronously. At this time, the movable plate 24 flips, which can drive the hook 25 to move away from each other and be in the open state. When the hoisting device moves up, the hook 25 can be brought closer together through the movable plate 24 for hanging. No manual hoisting is required, avoiding danger.

[0026] The limiting component 3 includes a slide groove 30, which is formed at both ends of the I-beam frame 21. A locking block 31 is slidably connected to the inner wall of the slide groove 30. A spring 32 is fixed to one end of the locking block 31 near the inner wall of the slide groove 30, and the other end of the spring 32 away from the locking block 31 is fixed to the inner wall of the slide groove 30. Fixing blocks 33 are fixed to both sides of the U-shaped frame 1, and sliding blocks 34 are slidably connected to both sides of the U-shaped frame 1. Magnets 35 are fixed to both sides of the U-shaped frame 1, and the magnets 35 are magnetically connected to the sliding blocks 34. The bottom of the locking block 31 away from the spring 32 is set as an inclined surface, and the ends of the fixing blocks 33 and sliding blocks 34 that are far apart from each other are also set as inclined surfaces. When the formwork 21 and the locking block 31 move down, and the locking block 31 is below the fixed block 33, the side of the locking block 31 away from the inclined plane abuts against the side of the fixed block 33 away from the inclined plane, which can limit the formwork 21 and make it easier to place the workpiece between the hooks 25. When the locking block 31 is below the sliding block 34, the connecting shaft 23, the fixed frame 22 and the formwork 21 are pulled up by the hoisting device. The locking block 31 drives the sliding block 34 to move closer to the fixed block 33. When the sliding block 34 is in contact with the surface of the fixed block 33, the locking block 31 will move along the surface of the sliding block 34 to the surface of the fixed block 33, which can release the limit and allow the workpiece to be hung.

[0027] In use, the connecting shaft 23 is connected to the lifting device. During lifting, the hook 25 touches the ground. At this time, the connecting shaft 23 and the fixed frame 22 drive the I-shaped frame 21 to move down synchronously. At this time, the movable plate 24 flips, which can drive the hook 25 away from each other and into the open state. Simultaneously, as the I-shaped frame 21 moves down, the locking block 31 moves down synchronously. At this time, the inclined surface of the locking block 31 abuts against the inclined surface of the fixed block 33, which can drive the locking block 31 to move into the slide groove 30. The spring 32 is compressed. When the locking block 31 is below the fixed block 33, the spring 32 is released, which can drive the locking block 31 to return to its original position. At this time, the side of the locking block 31 away from the inclined surface abuts against the side of the fixed block 33 away from the inclined surface, which can limit the I-shaped frame 21. At this time, the hook 25 is moved above the workpiece by the lifting device. Then, the I-shaped frame 21 is moved down again. At this time, the U-shaped frame... The bottom of frame 1 abuts against the top of the workpiece, which will not affect the normal downward movement of the I-beam frame 21. At this time, the inclined surface of the locking block 31 abuts against the top of the sliding block 34, causing the locking block 31 to move into the slide groove 30 again. When the locking block 31 is below the sliding block 34, the connecting shaft 23, the fixed frame 22, and the I-beam frame 21 are pulled upward by the hoisting device. At this time, the locking block 31 drives the sliding block 34 to move closer to the fixed block 33. When the sliding block 34 is in contact with the surface of the fixed block 33, the locking block 31 will move along the surface of the sliding block 34 to the surface of the fixed block 33, and the limit can be released. At this time, the movable plate 24 can normally drive the hooks 25 to move closer to each other, so that the workpiece can be hung. At this time, normal hoisting work can be carried out without manual hoisting, avoiding danger. At the same time, the magnet 35 attracts the sliding block 34 to reset, which is convenient for the next use.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
