Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment, and specifically to a heat treatment transfer and hoisting system. Background Technology

[0002] Currently, cast automotive parts require heat treatment in a furnace. These parts are placed in a basket and then lifted into the furnace by an overhead crane at the factory. Existing baskets can only lift one at a time, requiring multiple lifts, which is inefficient. There is a lack of heat treatment baskets that can be stacked and multiple baskets lifted simultaneously. The overhead crane hook needs to use a specialized lifting hook to lift the baskets, ensuring stability during lifting while also allowing for easy assembly and disassembly. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a heat treatment transfer and hoisting system.

[0004] This utility model includes a suspended platform and a hoisting hook.

[0005] The hanging basket includes a set of baskets stacked in sequence, with a hanging frame inside each basket. A set of hooks are arranged in a ring on the hanging frame, with the hooks on the lower baskets hanging on the bottom of the upper baskets.

[0006] The lifting hook includes a lifting platform and a set of outriggers. The top of the lifting platform is equipped with a lifting ring, and the set of outriggers is evenly distributed in a ring on the lifting platform. The ends of the outriggers are equipped with U-shaped forks.

[0007] During hoisting, the U-shaped fork is dragged under the hoisting frame.

[0008] The bottom of the basket consists of a set of vertical support bars and a set of horizontal support plates, with the horizontal support plates located above the vertical support bars.

[0009] The frame of the basketball hoop consists of a set of circular fences and three connecting posts. The set of circular fences is arranged from bottom to top, and the three connecting posts are evenly distributed in a ring inside the circular fences. The two ends of the vertical support rod and the horizontal support plate are respectively installed on the inner wall of the bottom circular fence.

[0010] The hanger consists of three suspension rods connected end to end, forming a triangular hanger; the hanger is installed on the top of the connecting column; the hook consists of a U-shaped claw body and a pair of hooks, with a baffle plate on the U-shaped claw body, and the U-shaped claw body is fitted onto the upper part of the connecting column; three pin rings are evenly distributed in a ring on the lower outer wall of the basket, and the pin rings are located below the corresponding hooks.

[0011] When the hook flips up and hooks onto the bottom of the upper basket, the baffle is located below the pin ring. Insert the locking pin into the pin ring and press the baffle into position using the locking pin.

[0012] The outrigger is an L-shaped outrigger, which is installed at an angle on the lifting platform; the U-shaped fork is installed horizontally at the end of the outrigger; a reinforcing bar is installed between two adjacent outriggers; the reinforcing bar is welded between two adjacent outriggers.

[0013] A set of outriggers consists of three arms.

[0014] The end of the outrigger is welded to the top of the U-shaped fork tail.

[0015] The lifting ring is welded to the center of the top of the lifting platform.

[0016] A set of outriggers are welded in a ring to the outer wall of the lifting platform.

[0017] The advantages of this invention are: multiple baskets are stacked and simultaneously hoisted into the heating furnace for heat treatment. The baskets have good stability, improving heat treatment efficiency. The hooks offer fast hoisting speed, good hoisting stability, and convenient assembly and disassembly.

[0028] As shown in the attached diagram, this utility model includes a suspended platform and a lifting hook.

[0029] The hanging basket includes a set of baskets 1 stacked in sequence. A hanging frame 2 is provided inside the basket 1. A set of hooks 3 are arranged in a ring on the hanging frame 2. The hooks 3 located on the lower basket 1 are hung on the bottom of the upper basket 1.

[0030] The lifting hook includes a lifting plate 11 and a set of support arms 12. The top of the lifting plate 11 is provided with a lifting ring 13, and the set of support arms 12 are evenly distributed in a ring on the lifting plate 11. The ends of the support arms 12 are provided with U-shaped forks 14.

[0031] During hoisting, the U-shaped fork 14 is dragged under the lifting frame 2.

[0032] The bottom of the basket 1 consists of a set of vertical support rods 4 and a set of horizontal support plates 5, with the horizontal support plates 5 located above the vertical support rods 4.

[0033] The frame of the basket 1 consists of a set of ring fences 6 and three connecting posts 7. The set of ring fences 6 are arranged from bottom to top, and the three connecting posts 7 are evenly distributed in a ring inside the ring fences 6. The two ends of the vertical support rods 4 and the horizontal support plates 5 are respectively installed on the inner wall of the bottom ring fence 6.

[0034] The hanger 2 consists of three suspension rods connected end to end, forming a triangular hanger; the hanger 2 is installed on the top of the connecting column 7; the hook 3 consists of a U-shaped claw body and a pair of hooks, with a baffle 8 on the U-shaped claw body, and the U-shaped claw body is fitted onto the upper part of the connecting column 7; three pin rings 9 are evenly distributed in a ring on the lower outer wall of the basket 1, and the pin rings 9 are located below the corresponding hook 3.

[0035] When the hook 3 flips up and hooks onto the bottom of the upper basket 1, the baffle 8 is located below the pin ring 9. The locking pin 10 is inserted into the pin ring 9, and the baffle 8 is pressed and positioned by the locking pin 10.

[0036] The outrigger 12 is an L-shaped outrigger, which is installed at an angle on the lifting plate 11; the U-shaped fork 14 is installed horizontally at the end of the outrigger 12; a reinforcing rod 15 is provided between two adjacent outriggers 12; the reinforcing rod 15 is welded between two adjacent outriggers 12.

[0037] There are three outriggers in a set of 12.

[0038] The end of the support arm 12 is welded to the top of the tail of the U-shaped fork 14.

[0039] The lifting ring 13 is welded to the center of the top of the lifting plate 11.

[0040] A set of support arms 12 are evenly welded in a ring on the outer wall of the lifting platform 11.

[0041] Example 1: The automotive parts requiring heat treatment are placed in basket 1. After stacking, multiple baskets are stacked sequentially from bottom to top. The hooks 3 on the lower baskets are flipped upwards and hooked onto the annular railing 6 of the upper basket. Then, the locking pins 10 are inserted into the pin rings 9, pressing and positioning the baffle 8 to prevent the hooks 3 from falling off. The gantry crane uses a special lifting hook to hook onto the uppermost lifting frame 2, lifting multiple baskets together and transporting them to the heating furnace for heat treatment.

[0042] When the baskets are stacked, the lower basket supports the upper basket via the hanger 2. The frame of the basket 1 is composed of a set of ring rails 6 and three connecting posts 7, which reduces the overall weight of the basket 1.

[0043] As shown in the attached diagram, after the car parts are loaded into the basket, the lifting hook moves to the top of the basket under the drive of the overhead crane. The workers rotate the lifting hook forward so that the U-shaped fork 14 is coupled with the top frame of the basket. The overhead crane lifts the basket through the lifting hook and then transfers it to the heating furnace for heat treatment.

[0044] The top suspension frame of the suspended basket is triangular. The suspension frame 2 is fixedly connected to the connecting column 7 on the basket. The U-shaped fork 14 is fitted onto the connecting column 7. During hoisting, the top surface of the U-shaped fork 14 contacts the bottom surface of the suspension frame 2, and the three U-shaped forks 14 simultaneously lift the suspended basket upward.

[0045] When it is necessary to remove the lifting hook, rotate the lifting hook in the opposite direction to disengage the U-shaped fork 14 from the basket, and then lift the lifting hook upwards.

[0046] The reinforcing rod 15 enhances the overall strength of the lifting hook, making it less prone to deformation and extending its service life.
