Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of strip steel production, and more specifically, to a disc-type looper cooling and lubrication device. Background Technology

[0002] In the strip steel rolling process, the disc looper, as a key device for storing and regulating strip steel tension, directly affects the surface quality of the strip steel and the service life of the equipment through its cooling and lubrication effect. However, in practical applications, traditional disc looper cooling and lubrication devices generally suffer from problems such as uneven cooling and lubrication and inconvenient spray angle adjustment. They are unable to form an effective lubrication layer on the strip steel surface through water spraying, resulting in increased friction between the strip steel and the looper rolls, severe wear between adjacent strip steel layers, and seriously restricting the strip steel production quality and equipment operating efficiency.

[0003] Existing cooling and lubrication devices mostly employ fixed-angle spray structures with single-position nozzles, resulting in a very small coverage area. This makes it impossible to adjust the spray angle in real-time according to the strip's running status and the position of the looper rolls. When the strip is stacked in the looper, the fixed spray angle struggles to cover the entire surface of the strip, especially at the contact points between the inner strip and the looper rolls. Insufficient lubrication can lead to severe friction, causing scratches or wear on the strip surface. For example, in high-speed rolling operations, changes in strip speed as it passes through the looper cause tension fluctuations. The fixed spray angle cannot adapt to these strip position shifts, making it difficult to accurately spray the liquid onto the contact area between the strip and the looper rolls. This not only wastes water resources but also fails to effectively reduce friction.

[0004] With the increasing demand for high-end strip steel products, traditional disc-type looper cooling and lubrication devices can no longer meet the needs of high-precision rolling production due to problems such as "fixed spray angle, poor lubrication effect, and low adjustment efficiency". Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a disc-type looper cooling and lubrication device, which solves the technical problems of uneven cooling and lubrication and inconvenient spray angle adjustment that are common in the practical application of traditional disc-type looper cooling and lubrication devices in the prior art.

[0006] According to one aspect, at least one embodiment of this disclosure provides a disc-type looper cooling and lubrication device, comprising: A vertical panel and a shield, wherein the shield is disposed on the vertical panel; A spray assembly is disposed on the vertical plate; A support and recycling assembly is disposed at the bottom of the upright plate; The spray assembly includes a pair of telescopic rods, which are fixed at both ends of the top of the upright plate. The output end of the telescopic rod is connected to a lifting frame. A connecting groove is provided at the bottom of the lifting frame. A swing rod is rotatably connected to the connecting groove through a pin. A spray pipe is provided on the lifting frame.

[0007] As a further technical solution, a connecting block is provided at the upper end of the swing rod, the shield is rotatably connected to the side end face of the connecting block by a pin, the spray pipe is fixed to the inner wall of the shield, and a number of nozzles are provided on the surface of the spray pipe.

[0008] As a further technical solution, an inlet pipe is provided at the top of the spray pipe, and bolts are threadedly connected to the side end face of the connecting block and the side end face of the lifting frame. One end of the bolt is provided with an anti-slip block. An upper spray pipe is provided at the top of the spray pipe, and a connecting seat is provided at the top of the shield. A swing frame is rotatably connected to the connecting seat through a pin. One end of the swing frame is fitted onto the upper spray pipe, and a nut is screwed onto one side of the swing frame. The nut is pressed against the surface of the connecting seat.

[0009] As a further technical solution, the supporting recycling component includes a collection box, a pair of slots are provided on the side surface of the collection box, the slots are opened vertically on the side surface of the collection box, and a pair of inserts are provided on the side surface of the upright plate.

[0010] As a further technical solution, the insert is inserted into the slot, the slot and the insert have a T-shaped cross-section, the bottom surface of the collection box is an inclined surface, and a drain pipe is provided on one side of the collection box.

[0011] As a further technical solution, the spray pipe has an overall U-shaped structure, and the nozzles are arranged in two rows on the surface of the spray pipe.

[0012] As a further technical solution, stabilizing rollers are rotatably connected to both ends of the side surface of the shield.

[0013] As a further technical solution, a pair of notches are provided on the top of the collection box.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, the spray assembly achieves precise spraying through a multi-dimensional adjustment structure, solving the problem of uneven cooling and lubrication in traditional devices. The telescopic rod uses an electric actuator to drive the lifting frame, allowing for vertical adjustment of the nozzle height. Combined with scale markings, the spraying distance is controlled within the optimal range, and the self-locking function of the electric actuator ensures height stability. The hinged design of the swing rod and the shield allows for adjustment of the spray angle within a certain range. The U-shaped spray pipe, paired with double-row fan-shaped nozzles, can uniformly cover the entire surface of the strip, conforming to its running trajectory. During adjustment, the anti-loosening bolts and anti-slip blocks are engaged to prevent vibration-induced loosening. The corrosion-resistant material and quick-connect pipe facilitate maintenance, effectively reducing friction between the strip and the looper rollers, improving surface quality, and extending equipment life.

[0015] 2. In this disclosure, the supporting recycling component achieves stable installation and convenient maintenance through a detachable structure of T-shaped slots and inserts. The inclined bottom design quickly collects the spray water into the drain pipe, where it is recycled after three-stage filtration, increasing water resource utilization to over 85%. The opening at the top of the collection box avoids the protective railing, ensuring no dead corners in the collection. The bottom drain outlet allows for regular removal of impurities, preventing sedimentation from affecting water circulation. This design solves the problem of incomplete spray water recycling in traditional devices, reduces corrosion of the looper rollers, extends equipment maintenance cycles, lowers industrial water consumption and maintenance costs, meets energy-saving standards, and promotes green and efficient strip steel production.

[0024] like Figures 1-4 As shown, it illustrates a disc-type looper cooling and lubrication device according to an embodiment of the present disclosure, comprising: A vertical plate 1 and a shield 2, wherein the shield 2 is disposed on the vertical plate 1; Spray assembly 3, wherein the spray assembly 3 is disposed on the vertical plate 1; A support and recycling assembly 4 is provided at the bottom of the upright plate 1; The spray assembly 3 includes a pair of telescopic rods 3-1, which are fixed to the top ends of the upright plate 1. A lifting frame 3-2 is connected to the output end of each telescopic rod 3-1. A connecting groove 3-3 is provided at the bottom of the lifting frame 3-2. A swing rod 3-4 is rotatably connected to the connecting groove 3-3 via a pin. A spray pipe 3-5 is mounted on the lifting frame 3-2. A connecting block 3-6 is provided at the upper end of the swing rod 3-4. A shield 2 is rotatably connected to the side face of the connecting block 3-6 via a pin. The spray pipe 3-5 is fixed to the inner wall of the shield 2. Several nozzles 3-7 are provided on the surface of the spray pipe 3-5. An inlet pipe 3-8 is provided at the top of the spray pipe 3-5. Bolts 3-9 are threadedly connected to the inner end face of the connecting block 3-6 and the inner end face of the lifting frame 3-2. An anti-slip block 3-10 is provided at one end of the bolt 3-9. An upper spray pipe 3-11 is provided at the top of the spray pipe 3-5. A connecting seat 3-12 is provided at the top of the shield 2. A swing frame 3-13 is rotatably connected to the connecting seat 3-12 through a pin. One end of the swing frame 3-13 is fitted onto the upper spray pipe 3-11. A nut 3-14 is screwed onto one side of the swing frame 3-13. The nut 3-14 is pressed against the surface of the connecting seat 3-12.

[0025] In some examples, a spray assembly 3 is designed to achieve the effect of adjusting the angle and height of water spraying lubrication on the strip surface. This assembly uses telescopic rods 3-1 fixed at both ends of the top of the vertical plate 1 as lifting supports. The lifting frame 3-2 connected to its output end can be adjusted vertically to adapt to strips of different specifications. The telescopic rods 3-1 are electric push rods, and the extension length can be precisely controlled by a controller. The connecting groove 3-3 in the lifting frame 3-2 is rotatably connected to the swing rod 3-4 through a pin. The connecting block 3-6 at the upper end of the swing rod 3-4 is hinged to the shield 2, allowing the shield 2 to swing around the pin within a range of ±15°, precisely adjusting the spray angle to conform to the running trajectory of the strip. The upper spray pipe 3-11 can spray downwards from the top for further coverage. The upper spray pipe 3-11 can be adjusted downwards by the swing frame 3-13 and the connecting seat 3-12 for support, and can also be locked at a fixed angle by tightening the nut 3-14. The sprinkler pipe 3-5 is made of corrosion-resistant PVC material and fixed to the inner wall of the shield 2. The fan-shaped nozzles 3-7, which are evenly distributed on the surface, face the steel strip. The top access pipe 3-8 is connected to the external water source through a quick connector for easy disassembly and maintenance.

[0026] When adjustment is required, loosen the anti-loosening bolts 3-9 of the connecting block 3-6 and the lifting frame 3-2, manually fine-tune the tilt angle of the shield 2, tighten the bolts 3-9, and then fix it by the toothed engagement of the anti-slip block 3-10 with the surface of the lifting frame 3-2 to prevent vibration from loosening; at the same time, the millimeter-level scale markings on the surface of the telescopic rod 3-1 can help to accurately adjust the height of the lifting frame 3-2, ensuring that the nozzle 3-7 and the strip surface maintain the optimal spraying distance of 10-15cm. The self-locking function of the electric push rod can maintain the stability of the height position and avoid displacement deviation after long-term operation.

[0027] Through precise height adjustment of telescopic rod 3-1, multi-angle adjustment of swing rod 3-4 and connecting block 3-6, and double anti-loosening fixing structure, spray assembly 3 can flexibly adapt to the strip lubrication needs under different working conditions.

[0028] like Figures 1-4 As shown in the figure, the supporting recycling component 4 in this embodiment includes a collection box 4-1. A pair of slots 4-2 are opened on the side surface of the collection box 4-1. The slots 4-2 are opened vertically on the side surface of the collection box 4-1. A pair of inserts 4-3 are provided on the side surface of the upright plate 1. The inserts 4-3 are inserted into the slots 4-2. The slots 4-2 and the cross-section of the vehicle are T-shaped. The bottom surface of the collection box 4-1 is an inclined surface. A drain pipe 4-4 is provided on one side of the collection box 4-1.

[0029] In some examples, a supporting recycling component 4 is designed to achieve efficient collection and recycling of sprinkler water. This component centers on a collection box 4-1, whose vertically opened T-shaped slots 4-2 on its side surface precisely engage with inserts 4-3 on the side surface of the upright plate 1. The anti-slip ridges on the inner wall of the slot 4-2 interlock with the grooves of the inserts 4-3, ensuring the collection box 4-1 is firmly installed at the bottom of the upright plate 1 while also providing shock resistance. The inner bottom surface of the collection box 4-1 features a steeply sloping design with a smooth surface to reduce water flow resistance, quickly guiding the water flowing from the sprinkler to a drain pipe 4-4 on one side. This water can then be connected to a water tank for filtration and reuse.

[0030] The detachable design of the T-shaped slot 4-2 and the plug 4-3 ensures that the collection box 4-1 can be quickly disassembled when cleaning is required. The sloping bottom guide design effectively improves the water recycling rate and reduces maintenance costs.

[0031] Through scientifically designed inclined bottom surface for water diversion, a stable T-shaped installation structure, and a comprehensive water circulation and filtration system, the support and recycling component 4 achieves sustainable utilization of spray water, meeting industrial energy-saving design standards.

[0032] For example, such as Figure 1 As shown, the spray pipe 3-5 has an overall U-shaped structure, and the nozzles 3-7 are arranged in two rows on the surface of the spray pipe 3-5.

[0033] In some examples, a U-shaped structure is used to distribute the spray pipes in two rows, resulting in more thorough and even spray coverage and better lubrication.

[0034] For example, such as Figure 1 As shown, stabilizing rollers 5 are rotatably connected to both ends of the side surface of the shield 2.

[0035] In some examples, the stabilizing roller 5 can support the surface of the strip during transport, improving stability while further ensuring even water coverage.

[0036] For example, such as Figure 1 As shown, the top of the collection box 4-1 has a pair of notches 6.

[0037] In some examples, the opening 6 can bypass the protective fence around the equipment, increase the height of other parts of the collection box 4-1, and improve the collection effect.

[0038] In practical use: the upright plate 1 is fixed to the equipment base next to the disc-type looper with expansion bolts. The shield 2 is hinged to the lifting frame 3-2 through the connecting block 3-6 and the swing rod 3-4. The spray pipe 3-5 is made of corrosion-resistant stainless steel and welded to the inner wall of the shield 2. The evenly distributed fan-shaped nozzles 3-7 face the running trajectory of the strip steel. The inlet pipe 3-8 is connected to the external water source pipe through a quick-connect connector for easy disassembly and maintenance. The telescopic rod 3-1 is fixed to the top beam of the upright plate 1 by an electric push rod. Its output end is rigidly connected to the lifting frame 3-2 through a flange. The collection box 4-1 supporting the recovery component 4 is installed at the bottom of the upright plate 1 through the T-shaped slot 4-2 and the plug 4-3. The end of the drain pipe 4-4 is connected to the filter water tank of the water circulation system. When in use, first start the electric push rod to adjust the height of the lifting frame 3-2. Control the distance between the nozzle 3-7 and the strip surface to 10-15cm using the scale markings. Then, move the swing rod 3-4 to adjust the tilt angle of the shield 2 so that the spray direction of the nozzle 3-7 is at a 45° angle to the running direction of the strip. After tightening the bolt 3-9, the position is locked by the anti-slip block and the toothed structure. The water source enters the spray pipe 3-5 through the inlet pipe 3-8 and is evenly sprayed onto the strip surface through the nozzle 3-7. The stabilizing roller 5 provides support and guidance for the strip. The inclined bottom surface in the collection box 4-1 quickly collects the sprayed water into the drain pipe 4-4. After three-stage filtration, it is recycled. The notch 6 precisely avoids the equipment guardrail to ensure that there are no dead corners in the collection.
