Description

Technical Field

[0001] This utility model relates to the field of steel smelting equipment technology, and in particular to a quenching lifting tool for steel smelting. Background Technology

[0002] In the fields of steel smelting or large-scale machining, workpieces typically require quenching after high-temperature treatment to improve their hardness and mechanical properties. The quenching process involves using a lifting device to hoist the high-temperature workpiece, transport it above the quenching tank, and slowly and steadily immerse it in the quenching liquid.

[0003] Existing lifting devices, such as ordinary electric hoists or chain lifting devices, often struggle to achieve precise and smooth fine-tuning when controlling the descent speed of workpieces (especially at the moment of immersion in water). Excessive speed or jerking can lead to uneven cooling of the workpiece, causing cracks or deformation, which seriously affects the quenching quality. At the same time, excessive speed may also cause the workpiece to impact the quenching tank, posing a safety hazard.

[0004] Furthermore, in continuous production operations, it is often necessary to handle workpieces of different shapes and sizes, which requires the lifting equipment to be able to quickly change hooks of different specifications. However, the hooks of traditional lifting equipment are usually fixed or connected by bolts, making the replacement process cumbersome, time-consuming, and labor-intensive, which greatly reduces the overall operating efficiency and flexibility of the production line.

[0005] Therefore, this utility model proposes a quenching lifting tool for steel smelting to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the steel smelting quenching lifting tool, such as the difficulty in achieving stable and precise lifting control when the workpiece is immersed in water for quenching, and the cumbersome and time-consuming operation when changing different hooks, this utility model aims to provide a steel smelting quenching lifting tool with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a quenching lifting tool for steel smelting, including a lifting assembly, a quick-release assembly, a lifting rod, and a lifting hook.

[0008] The lifting assembly includes a telescopic outer rod and a telescopic inner rod slidably disposed inside the telescopic outer rod; wherein, the inner wall of the telescopic outer rod is fixedly connected with a sliding tooth, and the top of the telescopic inner rod is rotatably connected with a gear, the gear meshing with the sliding tooth; the lifting assembly also includes a rocker arm, the rocker arm being fixedly connected to one side of the gear, and the rocker arm passing through a hand groove on one side of the telescopic outer rod.

[0009] The quick-release assembly is located at the bottom of the telescopic inner rod. The quick-release assembly includes a connector fixedly connected to the bottom of the telescopic inner rod. The bottom of the connector is provided with a groove, and a retaining plate is fixedly connected to the bottom of the groove.

[0010] A locking seat is fixedly connected to the top of the boom, and the locking seat cooperates with the connector of the quick-release assembly. The locking seat can be inserted into the groove and engaged with the locking plate. The hook is connected to the bottom of the boom.

[0011] Preferably, the bottom of the boom is provided with a rotating groove, and a rotating shaft is fixedly connected to the inner side of the rotating groove. The hook is rotatably connected to the outer periphery of the rotating shaft. This structure allows the hook to rotate freely, which is convenient for aligning with the workpiece during hoisting.

[0012] Preferably, the quenching hanger for steel smelting further includes a suspension beam, a hanging ring, and a fixing plate; one end of the hanging ring is fixedly connected to the bottom of the suspension beam, and the top of the fixing plate is fixedly connected to the other end of the hanging ring, for suspending the entire device on the supporting structure.

[0013] Preferably, to enhance structural stability, the quenching hanger for steel smelting further includes a reinforcing bar, the top of which is fixedly connected to the fixing plate, and the bottom of which is fixedly connected to the top of the telescopic outer rod. Preferably, the reinforcing bar is fixedly connected to opposite sides of the top of the telescopic outer rod to form a stable symmetrical support.

[0014] Preferably, the sliding teeth in the lifting assembly are arranged on opposite sides inside the telescopic outer rod. This arrangement ensures that the gears are subjected to balanced forces during meshing and transmission, guaranteeing a smooth and stable lifting process for the telescopic inner rod.

[0015] Preferably, the locking plate in the quick-release assembly is fixedly connected to the opposite sides of the bottom of the groove to achieve stable locking and quick positioning of the locking seat.

[0016] This utility model has the following beneficial effects:

This symmetrical layout makes the gear 204 evenly stressed during meshing transmission, thereby ensuring that the telescopic inner rod 203 can move up and down smoothly.

[0040] As a preferred embodiment, in order to achieve a fast and secure snap-fit ​​effect, the snap-fit ​​plate 303 inside the groove 302 of the connector 301 is specifically fixedly connected to the opposite sides of the bottom of the groove 302.

[0042] The working principle of this utility model of a quenching lifting tool for iron and steel smelting is as follows:

[0043] Connect and fix the hook 9 of the workpiece to the connector 301 by using the quick-release assembly 3. Then, rotate the rocker arm 206 to adjust the extension length of the telescopic inner rod 203 so that the hook 9 is lowered to a suitable height to hook the quenching workpiece. Then, rotate the rocker arm 206 in the opposite direction to lift the workpiece to the required height. Move the lifting device to transfer the workpiece to the top of the quenching tank. Adjust the lifting assembly 2 again to slowly put the workpiece into the quenching tank for quenching. After quenching, lift the workpiece and transfer it to the designated position. If it is necessary to change the type of workpiece, the hook 9 can be quickly replaced by using the quick-release assembly 3.

[0044] The overall device uses the cantilever beam 1 as the top foundation support structure. One end of the hanging ring 6 is fixedly connected to the bottom of the cantilever beam 1.

The rocker arm 206 extends to the outside through the hand groove 205 on one side of the telescopic outer rod 201. Rotating the rocker arm 206 drives the gear 204 to rotate synchronously. Under the meshing and limiting action of the sliding teeth 202, the gear 204 drives the telescopic inner rod 203 to move up and down inside the telescopic outer rod 201.

[0046] When the hook 9 needs to be replaced, the quick-release assembly 3 is set at the bottom of the telescopic inner rod 203. The connector 301 of the quick-release assembly 3 is connected to the bottom of the telescopic inner rod 203. The bottom of the connector 301 is provided with a groove 302. The bottom of the groove 302 is fixedly connected with a locking plate 303 located on opposite sides. The locking seat 305 fixedly connected to the top of the rod 304 can be inserted into the groove 302 and cooperate with the locking plate 303 to achieve the connection between the rod 304 and the connector 301.
