Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a crane for brake disc annealing. Background Technology

[0002] During the production of brake discs, annealing improves their mechanical properties. The brake discs are stored in baskets, and during annealing, the baskets are fed into a continuous annealing furnace together. Using a continuous annealing furnace increases production efficiency; therefore, in the annealing workshop, brake discs and baskets need to be constantly moved, for both pre-annealing transfer to the production line and post-annealing transport.

[0003] When transferring brake discs in the decommissioning workshop, the existing cranes do not have special lifting tools, so the brake discs can only be moved one basket at a time, which is relatively slow. Moreover, only one basket of brake discs can be moved at a time, especially for long-distance transport, resulting in low crane efficiency and wasted energy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crane for annealing brake discs, which solves the problems of low handling efficiency and high energy consumption caused by the lack of specialized lifting tools in existing annealing workshops for transferring brake discs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A crane for annealing brake discs includes a crane body and a lifting device. A winding trolley is provided below the horizontal arm of the crane body. The winding trolley is connected to a hook via a steel cable. The lifting device includes a lifting cable suspended on the hook. A lifting frame is fixed at the lower end of the lifting cable. Vertical side frames that are symmetrical on both sides and front and back are movably hinged to both sides of the lifting frame. A longitudinal connecting frame is fixed at the bottom of the side frames on both sides. Multiple support frames inserted into a tray are fixed on the opposite sides of the two connecting frames. Baskets equipped with brake discs are stacked on the tray. Positioning rods inserted into the grid holes of the baskets are fixed on the opposite sides of the side frames on both sides. A rotatable adjusting screw is vertically installed on the top of the hanger. A handwheel is fixed on the adjusting screw, and an adjusting frame is threadedly connected to the adjusting screw. The adjusting frame is movably hinged to the upper end of the side frames on both sides through a movable connecting rod.

[0006] Preferably, there are two suspension cables, and the ends of the two suspension cables are fixed at diagonal positions on the top of the gantry, and the middle parts of the two suspension cables are crossed and suspended on the hook.

[0007] Preferably, the side frame, connecting frame, support frame, and positioning rod are an integral fixed structure.

[0008] Preferably, the distance between the two side frames is equal to twice the lateral length of the basket.

[0009] Preferably, multiple positioning rods are equidistantly arranged on the opposite surfaces of the side frames on both sides in the vertical direction, and each corresponds to a multi-layered basket being stacked.

[0010] Preferably, the adjusting screw is located at the center of the top of the hanger, and the movable connecting rod is symmetrically arranged left and right and front and back.

[0011] Preferably, the movable link is inclined, and the height of the end of the movable link corresponding to the adjusting frame is greater than the height of the end of the corresponding side frame.

[0012] Preferably, the handwheel is located below the adjustment bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model uses a pallet to stack multiple frame brake discs and uses a special lifting tool to clamp the side frame. It can move multiple frame brake discs on a pallet at one time, which is highly efficient. It avoids unnecessary energy waste caused by frequent low-load and no-load operation of the crane, reduces total energy consumption, and solves the problem of low handling efficiency and high energy consumption caused by the lack of special lifting tools for the existing cranes used to transfer brake discs in the return workshop.

[0014] (2) The height of the adjustment frame can be adjusted by handwheel and adjustment screw. When the adjustment frame moves upward, the bottom of the side frame is pulled to swing open to both sides by the movable connecting rod. The support frame and positioning rod are respectively aligned with the pallet and the basket with brake disc stacked on the pallet. Adjusting the adjustment frame to move downward can drive the side frame to clamp the pallet and the basket. The design is specifically for the stacked baskets, which can be positioned to effectively prevent the stacked baskets from tipping over during hoisting and improve hoisting safety.

[0018] like Figure 1-6 As shown, this utility model provides a technical solution: a crane for brake disc annealing, including a crane body and a lifting device. A winding trolley 2 is provided below the horizontal arm 1 of the crane body. The winding trolley 2 is connected to a hook 3 via a steel cable. The lifting device includes a lifting cable 4 suspended on the hook 3. A lifting frame 5 is fixed to the lower end of the lifting cable 4. There are two lifting cables 4, and the ends of the two lifting cables 4 are respectively fixed at diagonal positions on the top of the lifting frame 5. The middle parts of the two lifting cables 4 are crossed and suspended on the hook 3. Both sides of the hanger 5 are movably hinged with vertical side frames 6 that are symmetrical in the left and right and front and back. The distance between the two side frames 6 is equal to twice the horizontal length of the basket 11. Multiple positioning rods 12 on the opposite sides of the two side frames 6 are equidistantly arranged in the vertical direction and correspond to the stacked multi-layer baskets 11 respectively. The bottom of the two side frames 6 is fixed with a longitudinal connecting frame 7. Multiple support frames 9 are fixed to the opposite sides of the two connecting frames 7 and inserted into the tray 8. Baskets 11 equipped with brake discs 10 are stacked on the tray 8. Positioning rods 12 inserted into the grid holes of the baskets 11 are fixed to the opposite sides of the side frames 6. The side frames 6, connecting frames 7, support frames 9 and positioning rods 12 are a fixed structure. A rotatable adjusting screw 13 is vertically installed on the top of the hanger 5.
