Description

Technical Field

[0001] This utility model belongs to the technical field of hook equipment, and in particular relates to a temperature-controlled automatic unhooking device. Background Technology

[0002] In engineering production processes, samples often need to be suspended by hooks for physical or chemical treatment, especially in the case of high-temperature quenching. Quenching generally involves heating the sample to a certain temperature using high-temperature equipment, followed by gas quenching or liquid quenching. For liquid quenching, the high-temperature sample is often allowed to fall freely into a liquid-filled quenching tank. Therefore, ensuring the safe and stable descent of the heated object into the quenching tank at the required heating temperature to successfully complete the quenching process has always been a key consideration for various high-temperature quenching devices.

[0003] Currently, hooks on the market are generally divided into manual unhooking and automatic unhooking. However, in the high-temperature environment of quenching, manual unhooking is basically impossible. Although there are many types of automatic unhooking devices, the existing automatic unhooking devices are relatively complex in structure. And most of the devices that use electric devices to achieve unhooking still require manual operation of some buttons to complete. This means that in the high-temperature quenching device, before the sample reaches the temperature that needs to be quenched, someone needs to be present to observe and wait. This is not only time-consuming, but also prone to causing delays, making the manually controlled unhooking time lag behind the optimal quenching time. Utility Model Content

[0004] The purpose of this invention is to provide a temperature-controlled automatic unhooking device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A temperature-controlled automatic unhooking device includes a flange chuck four-way, the upper part of which is provided with a thermocouple blind plate and a thermocouple hole is provided on the thermocouple blind plate, the left part of which is provided with an observation piece, and the right part of which is provided with a bushing chuck, and the bushing chuck is provided with an unhooking component.

[0007] The unhooking assembly includes an electromagnet, which is fixed to the bushing chuck by a connecting plate. A rotating shaft fixed at one end of the electromagnet is located inside the bushing chuck. A hook is fixed to one end of the rotating shaft by bolts. The hook is located at the center of the flange chuck four-way.

[0008] Preferably, the observation element includes a closed plate fixed to the left side of the flange chuck four-way, and the closed plate is provided with an observation window.

[0009] Preferably, the flange chuck four-way lower part is sealed to the furnace tube.

[0010] The beneficial effects are as follows: The electromagnet set in this utility model is connected to the control panel through wires. The temperature measuring thermocouple can transmit the heating temperature to the screen of the control panel in real time. The control panel can be programmed. When the temperature reaches the set value, the electromagnet is energized and rotates. The hook and the rotating shaft also rotate synchronously, which can make the sample unhooking process timely and accurate, prevent lag in quenching or other test processes, and improve the applicability and flexibility of the overall device.

[0018] The technical solution of this utility model will be further explained below with reference to the accompanying drawings:

[0019] like Figures 1-4As shown, a temperature-controlled automatic unhooking device includes a flange chuck four-way connector 4. A thermocouple blind plate 5 is fixed to the upper part of the flange chuck four-way connector 4. A thermocouple hole 10 is provided on the thermocouple blind plate 5. An observation element is provided on the left part of the flange chuck four-way connector 4. The observation element includes a closed plate 6 fixed to the left side of the flange chuck four-way connector 4. An observation window 9 is provided on the closed plate 6. The observation window 9 can observe the suspension status of the hook 8 at any time and adjust the set temperature value at any time to ensure its accuracy. Once an abnormality is detected, such as a broken suspension wire, the test can be terminated immediately to ensure safety.

[0020] The right-hand side of the flange chuck four-way 4 is equipped with a bushing chuck 3, and a release assembly is provided on the bushing chuck 3. The release assembly includes an electromagnet 1. One end of the electromagnet 1 is connected to the control panel via an electric wire. The electromagnet 1 is fixed to the bushing chuck 3 via a connecting plate 2. A rotating shaft 7 fixed at one end of the electromagnet 1 is located inside the bushing chuck 3. A hook 8 is fixed to one end of the rotating shaft 7 via bolts. The hook 8 is located at the center inside the flange chuck four-way 4. The lower part of the flange chuck four-way 4 is sealed to the furnace tube.

[0021] Both the rotating shaft 7 and the hook 8 are made of stainless steel, which has high strength and good heat resistance. The shape of the rotating shaft 7 is cleverly designed. When it is not rotating, its end can effectively suspend the wire, and the raised end can prevent the wire from slipping off the hook 8. When it needs to be released, the hook 8 rotates 90° counterclockwise, and the wire can smoothly slide off the arc end of the hook 8, thus entering the liquid quenching tank in free fall to complete the quenching. This hook 8 structure will not cause a large horizontal deviation of the sample during the fall, preventing the sample from hitting the furnace wall or other parts of the equipment during the fall.

[0022] Working principle: During use, the connecting plate 2, bushing chuck 3, flange chuck four-way 4, thermocouple blind plate 5, and observation window 9 are connected by clamps and sealing rings, ensuring connection strength and structural sealing. This prevents air or dust from entering the pipeline during sample heating and quenching, thus preventing impurities from affecting the test results. The thermocouple blind plate 5 has thermocouple holes for installing thermocouples, allowing real-time temperature measurement of the furnace interior. The sealing plate 6 has a quartz observation window 9, allowing real-time observation of the hooks 8 inside.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
