Description

Technical Field

[0001] This utility model relates to the technical field of lifting tools for nickel anode plate insulation boxes, and in particular to a self-unloading lifting tool for nickel anode plate insulation boxes. Background Technology

[0002] In the non-ferrous metal smelting industry, nickel anode plates are an important production material, and their production and transportation directly affect quality. Nickel anode plate insulation boxes are used to maintain temperature and ensure product quality.

[0003] The nickel anode plate insulation boxes in the nickel smelting and casting workshop of the nickel smelter are mainly used for the slow cooling and storage of nickel anode plates. They need to be transported to the reverberatory furnace workshop in turn, and after being filled with anode plates, they are transported to the slow cooling workshop by flatbed trucks. The insulation boxes are then hoisted and stored using lifting lugs.

[0004] Currently, the lifting device for nickel anode plate insulation boxes is a four-limb chain. Using this device for frequent handling is not only labor-intensive and cumbersome, but also can damage the lifting lugs of the insulation box. The lifting and lowering of the insulation box poses a great safety risk. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a self-unloading lifting device for nickel anode plate insulation boxes, which solves the problems of large workload and cumbersome operation of existing four-limb chain lifting devices for transportation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A self-unloading lifting device for a nickel anode plate insulation box includes a supporting connecting rod. The top of the supporting connecting rod is connected to a crane hook via a lifting component. Clamping components are installed at both ends of the bottom surface of the supporting connecting rod. Each clamping component consists of a rotating connecting rod and a rotating clamping arm. There are two rotating connecting rods. One end of each rotating connecting rod is hinged and rotatably mounted on the end of the supporting connecting rod. A rotating clamping arm is hinged to the other end of each rotating connecting rod. The two opposing rotating clamping arms are staggered and have clamps on their free ends. The jaws of the clamps are facing each other. A supporting inverted ladder frame is installed at the bottom of the supporting connecting rod. A cylinder is inverted at the bottom of the supporting inverted ladder frame. The telescopic end of the cylinder is connected to a limit connecting plate. The four corners of the limit connecting plate are rotatably connected to the inner sides of the four rotating clamping arms. When the cylinder extends, the limiting connecting plate pushes the inner side of the rotating clamping arm downward, forcing the rotating clamping arm to rotate around the hinge point with the limiting connecting plate. The clamps at its free end close relative to each other due to the staggered arrangement, completing the circumferential clamping of the side of the insulation box. When the cylinder retracts, the limiting connecting plate pulls the rotating clamping arm upward, and the clamps open simultaneously to release, completing the self-unloading of the insulation box.

[0008] Limit plates are installed on the outer sides of the two adjacent rotating clamping arms, and fixed inclined plates are installed on the limit plates. When the clamps hold the insulation box, the limit plates fit against the side of the insulation box to counteract the swing torque of the insulation box during the lifting process.

[0009] The lifting component includes a fixed plate, with connecting lifting rings rotatably mounted at both ends of the fixed plate. The two connecting lifting rings are connected by a hook lifting ring, which is connected to the overhead crane hook. The overhead crane hook connects the two connecting lifting rings via the hook lifting ring. The two ends of the connecting lifting rings and the fixed plate rotate, allowing the lifting force to automatically adjust its angle according to the direction of the crane's movement. This prevents torque caused by horizontal deviation of the lifting device and ensures that the lifting device remains in a vertically stressed state during the lifting process.

[0010] The jaws of the clamps are fitted with anti-slip pads.

[0011] The hinge points of adjacent rotating links and rotating clamping arms are connected by rotating shafts.

[0012] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a cylinder as the core power source and achieves automatic clamping and release of the insulation box through a mechanical transmission path of cylinder extension / retraction, limit connecting plate transmission, and rotating clamping arm linkage. In use, the cylinder extends, and the limit connecting plate pushes the inner side of the rotating clamping arm downwards, forcing the rotating clamping arm to rotate around the hinge point with the limit connecting plate. The clamps at its free end close relative to each other due to their staggered arrangement, completing a wraparound clamping of the insulation box's side. When the cylinder retracts, the limit connecting plate pulls the rotating clamping arm upwards, and the clamps simultaneously open to release the insulation box, completing its self-unloading. Compared with existing four-limb chain lifting devices, this invention greatly simplifies the handling process, reduces the workload, and lowers the complexity of the operation. Meanwhile, the lifting device uses clamps to hold the insulated box, avoiding the frequent hooking and unhooking of the lifting lugs of the insulated box that is common with traditional lifting devices. This effectively reduces damage to the lifting lugs and significantly lowers the safety risks during the lifting and transport of the insulated box. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] A self-unloading lifting device for a nickel anode plate insulation box includes a support connecting rod 1. The top of the support connecting rod 1 is connected to a crane hook via a lifting component 2. Clamping components are installed at both ends of the bottom surface of the support connecting rod 1. The clamping components consist of rotating connecting rods 3 and rotating clamping arms 4. There are two rotating connecting rods 3. One end of the two rotating connecting rods 3 is hinged and rotatably installed at the end of the support connecting rod 1. Rotating clamping arms 4 are respectively hinged to the other end. The two opposing rotating clamping arms 4 are staggered and their free ends are equipped with clamps 5. The jaws of the clamps 5 are arranged opposite each other. A support inverted ladder frame 6 is installed at the bottom of the support connecting rod 1. A cylinder 7 is invertedly installed at the bottom of the support inverted ladder frame 6. The telescopic end of the cylinder 7 is connected to a limit connecting plate 8. The four corners of the limit connecting plate 8 are rotatably connected to the inner sides of the four rotating clamping arms 4. When the cylinder 7 extends, the limiting connecting plate 8 pushes the inner side of the rotating clamping arm 4 downward, forcing the rotating clamping arm 4 to rotate around the hinge point with the limiting connecting plate 8. The clamps 5 at its free end close relative to each other due to the staggered arrangement, completing the circumferential clamping of the side of the insulation box. When the cylinder 7 retracts, the limiting connecting plate 8 pulls the rotating clamping arm 4 upward, and the clamps 5 open simultaneously to release, completing the self-unloading of the insulation box.

[0018] Limiting plates 9 are installed on the outer sides of the two adjacent rotating clamping arms 4, and fixed inclined plates 10 are installed on the limiting plates 9. When the clamps 5 clamp the insulation box, the limiting plates 9 fit against the side of the insulation box to counteract the swing torque of the insulation box during the lifting process.

[0019] The lifting component 2 includes a fixed plate 201, with connecting lifting rings 202 rotatably mounted at both ends of the fixed plate 201. The two connecting lifting rings 202 are connected by hook lifting rings 203, which are connected to the crane hook. The crane hook connects the two connecting lifting rings 202 via the hook lifting rings 203. The rotation of the connecting lifting rings 202 and the two ends of the fixed plate 201 allows the lifting force to automatically adjust its angle according to the direction of crane movement, preventing torque caused by horizontal deviation of the lifting device and ensuring that the lifting device remains in a vertically stressed state during the lifting process.

[0020] Anti-slip pads 11 are installed on the jaws of the clamp 5.

[0021] The hinge points of adjacent rotating links 3 and rotating clamping arms 4 are connected by rotating shafts 12.

[0022] When using:

[0023] The crane moves the lifting device above the nickel anode plate insulation box. The telescopic end of cylinder 7 extends, and the limiting connecting plate 8 pushes the inner side of the rotating clamping arm 4 downwards, forcing the rotating clamping arm 4 to rotate around its hinge point with the limiting connecting plate 8. The clamps 5 at its free end close relative to each other due to their staggered arrangement, completing a wraparound clamping of the insulation box's side. At this time, the limiting plate 9 adheres to the side of the insulation box, counteracting the swing torque of the insulation box during lifting and providing additional fixed support. After clamping, the crane lifts and transports the insulation box to the designated location. When it is necessary to unload the insulation box, the telescopic end of cylinder 7 retracts, causing the rotating clamping arm 4 to rotate in the opposite direction, releasing the clamps 5 and achieving self-unloading.

[0024] Cylinder 7 provides precise power, the four-bar linkage converts linear motion into clamping action, the limiting components enhance structural stability, and the lifting component 2 achieves flexible force transmission. This collaborative mechanism enables the lifting device to not only meet the lifting requirements of insulated boxes but also reduce manual intervention through automated operation, achieving comprehensive benefits such as improved efficiency, reduced safety accidents, and lower maintenance costs.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
