Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery technology, and in particular to a cooling cover for metallurgical machinery. Background Technology

[0002] Metallurgical machinery cooling hoods are key pieces of equipment on forging or smelting production lines, used to rapidly cool high-temperature forgings or workpieces to control their microstructure and mechanical properties. During the cooling process, the cooling hood typically uses internal nozzle modules to evenly spray coolant onto the high-temperature forgings.

[0003] The environment at metallurgical sites is relatively harsh. Oxide scale produced by high-temperature forgings, impurities in water, or coking of coolant can easily cause the nozzles on the nozzle module to become clogged or worn. In existing technical solutions, the nozzle module is often integrally welded to the cooling shroud or fixedly connected by bolts and flanges. At the same time, its coolant delivery pipe also uses hard connection methods such as threads or flanges.

[0004] This fixed connection structure makes on-site maintenance and replacement extremely difficult and time-consuming when the nozzle module becomes clogged or damaged. Maintenance personnel must stop the production line and carry tools to disassemble a large number of fixing bolts or pipe joints in order to remove the nozzle module for repair or replacement. This prolongs the equipment downtime, reduces production efficiency, and also increases the cost of spare parts.

[0005] Therefore, this utility model proposes a cooling cover for metallurgical machinery to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of metallurgical machinery cooling hoods, where the nozzle module is fixedly connected to the hood body and pipelines, resulting in difficult maintenance and repair, cumbersome and time-consuming disassembly and assembly, and long downtime, this utility model aims to provide a metallurgical machinery cooling hood with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a cooling cover for metallurgical machinery, including: a shielding mechanism, a nozzle module, an infusion pipe, a locking mechanism, and a quick-release mechanism.

[0008] The shielding mechanism includes a shield body with a locking groove. The nozzle module is detachably mounted on the shield body. The nozzle module has a connecting nozzle with a slot on its outer wall. The locking mechanism, quick-release mechanism, shielding mechanism, nozzle module, and infusion tubing are combined in the following way:

[0009] The locking mechanism is installed on the nozzle module. The locking mechanism includes a handle, a connecting post, a locking tongue, and a second spring. The connecting post is fixedly connected to the handle, and the locking tongue is fixedly connected to the connecting post. The second spring is located between the two locking tongues and its two ends abut against the two locking tongues respectively. The locking tongues are adapted to retractably engage in the locking grooves on the cover. This locking mechanism is used to achieve quick mechanical fixation between the nozzle module and the cover.

[0010] One end of the quick-release mechanism is connected to the infusion tube, and the other end is adapted to detachably connect to the connector. The quick-release mechanism includes a sliding wall and a pivotally mounted clamping plate. A locking plate is provided on the clamping plate, which is adapted to snap into the slot on the connector. This quick-release mechanism is used to realize the rapid fluid connection between the nozzle module and the infusion tube. Through the coordinated setting of the locking mechanism and the quick-release mechanism, the overall quick assembly and disassembly of the nozzle module is realized.

[0011] Preferably, the quick-release mechanism also includes a connecting tube, and the sliding wall is slidably fitted onto the outer wall of the connecting tube. This structure provides reliable guidance and support for the reciprocating sliding or rotation of the sliding wall.

[0012] Preferably, as a further embodiment of the connecting tube arrangement, the clamp is pivotally connected to the end of the connecting tube, so that the clamp can open or tighten with the end of the connecting tube as the pivot center.

[0013] Preferably, in order to achieve control of the clamping plate by the sliding wall, a limit post is provided on the clamping plate, and an L-shaped groove is provided on the inner wall of the sliding wall. The limit post can be slidably and securely accommodated in the L-shaped groove. By rotating and pushing the sliding wall, the groove wall of the L-shaped groove can drive the limit post, thereby driving the clamping plate to achieve precise locking and releasing actions.

[0014] Preferably, the quick-release mechanism further includes a first spring for providing an elastic restoring force or clamping force during the movement of the sliding wall, ensuring the reliability of the connection.

[0015] Preferably, the quick-release mechanism further includes a limiting block, and a first spring is sleeved on the outer wall of the connecting tube and located between the inner wall of the sliding wall and the limiting block, for accumulating or releasing elastic force when the sliding wall slides, making the operation more effortless or automatically resetting.

[0016] Preferably, the shielding mechanism also includes a bracket for providing stable mounting support for the shield.

[0017] Preferably, as a further improvement to the shielding mechanism, the shielding mechanism also includes a conveyor belt, a support bracket for supporting the shield, and the conveyor belt installed on the support bracket and passing through the interior of the shield, for carrying and conveying high-temperature forgings continuously through the cooling area below the shield.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting a locking mechanism and a quick-release mechanism, enables the nozzle module to be quickly mechanically disassembled from the cover as an independent unit and quickly disconnected from the fluid connection with the infusion pipe. This solves the problem in the prior art that the nozzle module is difficult to maintain when it is blocked or damaged due to fixed connection, and requires disassembly of the pipeline or cover, resulting in long downtime. It achieves the technical effect of completely modularizing the nozzle module, enabling on-site replacement in a short time, shortening equipment maintenance downtime and improving production efficiency.

[0020] 2. This utility model, by setting a locking mechanism consisting of a handle, a connecting column, a locking tongue, and a second spring, uses the spring force to achieve automatic locking and squeezes the handle to achieve quick unlocking. This solves the problems of existing technologies where nozzle modules are mostly fixed with bolts, which are cumbersome to install and disassemble, require special tools, and are time-consuming. It achieves the technical effect of extremely simple mechanical fixing operation, stable and reliable locking, and quick installation and removal without tools.

[0021] 3. This utility model, by setting up a quick-release mechanism consisting of a sliding wall, an L-shaped groove, a limiting post, a clamping plate, and a slot in precise cooperation, uses the rotation and sliding of the sliding wall to control the opening and closing of the clamping plate. This solves the problem in the prior art that coolant pipelines mostly use flange or threaded connections, which are prone to leakage and time-consuming and laborious during disassembly. It achieves the technical effect of fast fluid pipeline connection operation, reliable sealing, and further improves the overall replacement efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 4 This utility model provides a cooling cover for metallurgical machinery, which aims to solve the problems in the prior art where the nozzle module 4 is usually fixedly connected to the cover body 101, resulting in difficult maintenance and repair, long downtime and high spare parts costs when the nozzle is blocked or damaged.

[0030] The metallurgical machinery cooling cover includes a shield mechanism 1, a nozzle module 4, a locking mechanism 3, and a quick-release mechanism 2. The shield mechanism 1 provides cooling space and a mounting base. The nozzle module 4 sprays the forgings. The locking mechanism 3 enables quick mechanical fixing and disassembly between the nozzle module 4 and the shield mechanism 1. The quick-release mechanism 2 enables quick fluid connection and disconnection between the nozzle module 4 and the external liquid inlet pipe 201.

[0031] The shielding mechanism 1 includes a shield body 101, on which a locking groove 305 for locking is provided. The shielding mechanism 1 also includes a bracket 102, which supports the shield body 101. The shielding mechanism 1 also includes a conveyor belt 103, which is installed on the bracket 102 and passes through the inside of the shield body 101 for conveying high-temperature forgings. The nozzle module 4 is adapted to be detachably installed on the shield body 101. The nozzle module 4 is provided with a connecting nozzle 209, and a slot 210 is provided on the outer wall of the connecting nozzle 209. The slot 210 is used to cooperate with the quick-release mechanism 2 to achieve rapid fluid connection.

[0032] Please refer to Figure 1 and Figure 4The locking mechanism 3 is installed on the nozzle module 4 to achieve mechanical fixation between the nozzle module 4 and the cover 101. The locking mechanism 3 includes a handle 301, a connecting post 302, a locking tongue 303, and a second spring 304. The connecting post 302 is fixedly connected to the handle 301, and the locking tongue 303 is fixedly connected to the connecting post 302. When the operator squeezes the handle 301, the handle 301 drives the connecting post 302, thereby causing the locking tongue 303 to retract inward. The second spring 304 is located between the two locking tongues 303, and the two ends of the second spring 304 abut against the two locking tongues 303 respectively. The second spring 304 is used to provide elastic restoring force. When the handle 301 is released, the second spring 304 pushes the two locking tongues 303 to extend outward, so that the locking tongues 303 can be retracted and locked into the locking groove 305 on the cover 101, thereby achieving quick fixation and locking between the nozzle module 4 and the cover 101.

[0033] One end of the quick-release mechanism 2 is connected to the infusion tube 201, and the other end is adapted to be detachably connected to the connecting nozzle 209. The quick-release mechanism 2 includes a connecting tube 202, a sliding wall 205, a clamping plate 206, and a first spring 204. The sliding wall 205 is slidably sleeved on the outer wall of the connecting tube 202. The quick-release mechanism 2 also includes a limiting block 203. The first spring 204 is sleeved on the outer wall of the connecting tube 202 and is located between the inner wall of the sliding wall 205 and the limiting block 203. The first spring 204 is used to provide a reset elastic force or a clamping force.

[0034] The quick-release mechanism 2 also includes a pivotally mounted clamping plate 206, which is pivotally connected to the end of the connecting pipe 202. A locking plate 207 is provided on the clamping plate 206. In order to realize the opening and closing control of the sliding wall 205 on the clamping plate 206, a limiting post 208 is provided on the clamping plate 206. An L-shaped groove is provided on the inner wall of the sliding wall 205. The limiting post 208 is slidably and lockingly accommodated in the L-shaped groove. When the operator rotates and slides the sliding wall 205, the groove wall of the L-shaped groove drives the limiting post 208, thereby causing the clamping plate 206 to open or close.

[0035] Meanwhile, the connecting nozzle 209 on the nozzle module 4 is provided with a corresponding slot 210. In the assembled state, the sliding wall 205 drives the clamping plate 206, so that the clamping plate 207 on the clamping plate 206 is adapted to fit into the slot 210 on the connecting nozzle 209, thereby completing the locking and ensuring the speed and sealing reliability of the fluid connection between the infusion tube 201 and the nozzle module 4.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0037] In a preferred embodiment, to refine the internal structure of the quick-release mechanism 2, the quick-release mechanism 2 further includes a connecting tube 202, and a sliding wall 205 is slidably sleeved on the outer wall of the connecting tube 202. As a further preferred embodiment, a clamping plate 206 is pivotally connected to the end of the connecting tube 202. In order to achieve locking control of the sliding wall 205 on the clamping plate 206, a limiting post 208 is provided on the clamping plate 206. An L-shaped groove is provided on the inner wall of the sliding wall 205, and the limiting post 208 is slidably and clampably accommodated in the L-shaped groove. As a further preferred embodiment, in order to provide elastic reset or clamping force, the quick-release mechanism 2 further includes a first spring 204. In addition, the quick-release mechanism 2 also includes a limiting block 203. The first spring 204 is sleeved on the outer wall of the connecting tube 202 and is located between the inner wall of the sliding wall 205 and the limiting block 203.

[0038] In another preferred embodiment, in order to construct a complete cooling shroud structure, the shroud mechanism 1 also includes a bracket 102, which supports the shroud body 101. In addition, in order to realize the automated conveying of the forgings, the shroud mechanism 1 also includes a conveyor belt 103, which is mounted on the bracket 102 and passes through the interior of the shroud body 101.

[0039] The working principle of this metallurgical machinery cooling cover is as follows:

[0040] When installing the nozzle module 4, first operate the locking mechanism 3 by squeezing the handle 301. The handle 301 drives the connecting post 302 fixedly connected to it, and the connecting post 302 drives the locking tongue 303 fixedly connected to it to retract inward and compress the second spring 304 located between the two locking tongues 303. At this time, insert the locking mechanism 3 installed on the nozzle module 4 into the interface of the cover 101. Release the handle 301. The two ends of the second spring 304 abut against the two locking tongues 303 respectively. Under the elastic force of the second spring 304, the locking tongue 303 is pushed out and locked into the locking groove 305 on the cover 101, thus completing the mechanical fixation of the nozzle module 4.

[0041] Subsequently, the quick-release mechanism 2 is connected, and the sliding wall 205, which is slidably fitted on the outer wall of the connecting tube 202, is operated, for example, by rotating and sliding, so that the sliding wall 205 compresses the first spring 204 located between the inner wall of the sliding wall 205 and the limiting block 203. At the same time, the L-shaped groove on the inner wall of the sliding wall 205 drives the clamping plate 206 pivotally connected to the end of the connecting tube 202 to open through the limiting post 208 housed therein. The opened clamping plate 206 is aligned with the connecting nozzle 209 on the nozzle module 4, so that the locking plate 207 on the clamping plate 206 is aligned with the locking groove 210 on the outer wall of the connecting nozzle 209. The sliding wall 205 is operated in the opposite direction. Under the elastic force of the first spring 204 or the locking action of the L-shaped groove, the sliding wall 205 drives the clamping plate 206 to tighten, so that the locking plate 207 is locked into the locking groove 210, thus completing the fluid connection between the infusion tube 201 and the nozzle module 4.

[0042] When the equipment is running, the high-temperature forgings enter the lower part of the cover 101 through the conveyor belt 103 installed on the bracket 102 and passing through the inside of the cover 101. The coolant pump pumps the coolant in through the delivery pipe 201. The coolant flows through the connecting pipe 202 and the connecting nozzle 209 of the quick release mechanism 2 in sequence, enters the nozzle module 4, and is sprayed onto the forgings by the nozzle array on the nozzle module 4 for cooling.

[0043] When the nozzle module 4 needs maintenance or replacement, the operator first reverses the sliding wall 205 of the quick-release mechanism 2 to loosen the clamp 206, disengage the clamp 207 from the slot 210, and disconnect the fluid connection. Then, the operator squeezes the handle 301 of the locking mechanism 3 to disengage the locking tongue 303 from the locking slot 305, allowing the entire nozzle module 4 to be quickly removed for replacement, thus shortening downtime for maintenance. Through the synergistic effect of the locking mechanism 3 and the quick-release mechanism 2, this invention solves the problems of difficult maintenance and long replacement time of the cooling cover nozzle module 4 in the prior art.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
