Description

Technical Field

[0001] This invention relates to the field of steel rolling production equipment technology, specifically to a cooling system for moving gears on a cooling bed. Background Technology

[0002] As one of the important products of the steel industry, rebar bars are widely used in the construction, machinery and metal products industries. In recent years, with economic development, production demand has continued to increase. In the bar rolling production line, the rolled parts after rolling are transported to the skirt plate loading point by roller conveyor, and then loaded onto the cooling bed by the skirt plate of the skirt plate loading system. Through the cooperation between the moving teeth and stationary teeth of the cooling bed, the rolled parts can move continuously on the cooling bed for further cooling until the rolled parts move to the next process.

[0003] However, during the process of moving the rolled piece, the temperature of the cooling bed is too high and it is difficult to ventilate and dissipate heat, which can lead to heat deformation of the equipment, equipment damage and product quality. In addition, the lubricating oil in the lubrication parts melts faster and the lubrication effect is low, which cannot achieve the desired lubrication effect. At the same time, the ambient temperature is high when maintenance personnel are performing maintenance, which can easily cause heatstroke and prevent the maintenance from being carried out normally. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cooling system for moving gears in a cooling bed, which solves the problems of excessively high cooling bed temperature making ventilation and heat dissipation difficult, leading to equipment deformation and damage, product quality issues, accelerated melting of lubricating oil resulting in low lubrication effect, and high ambient temperature preventing maintenance personnel from carrying out maintenance normally.

The connecting rods are all L-shaped.

[0007] Preferably, an inclined platform is fixedly connected to the other side of the maintenance compartment, and multiple evenly distributed ventilation slots are provided on the side of the protective cover close to each other. A controller is fixedly connected to the upper middle part of the rear wall of the maintenance compartment near the ventilation window, and a temperature sensor is fixedly connected to the upper middle part of the rear wall of the maintenance compartment near the inclined platform. The controller is electrically connected to the temperature sensor, the fan, and the stepper motor respectively.

[0008] Preferably, a support frame is fixedly connected to the top of the base, and slide rails are fixedly connected to the four corners of the top of the support frame. A slider is slidably connected to the top of each slide rail. The slider is fixedly connected to both sides of the first side plate near the middle of the base. The first side plate is provided with multiple evenly distributed triangular grooves. Protective pads are fixedly connected to the side walls of each triangular groove. The protective pads are all made of tungsten material.

[0009] Preferably, a support block is fixedly connected to each of the four corners of the top center of the base, and a first bearing seat is fixedly connected to the top center of each support block. A first rotating shaft is rotatably connected to the side of the first bearing seat near the center of the base. A first connecting plate is fixedly connected to the end of the first rotating shaft away from the first bearing seat. A second rotating shaft is fixedly connected to the upper part of the first connecting plate. A second bearing seat is rotatably connected to the end of the second rotating shaft away from the first connecting plate. An oil inlet pipe is fixedly connected to the middle of one side of both the first and second bearing seats. A valve is provided in the middle of the outer periphery of each oil inlet pipe.

[0010] Preferably, the second bearing seat is fixedly connected to both sides of the support plate on the side near the middle of the base. Multiple evenly distributed vertical plates are fixedly connected to the middle of the top of the support plate. A horizontal plate is fixedly connected to the top of the vertical plate. A second side plate is fixedly connected to the front side of the horizontal plate and to the rear side of the horizontal plate. Each of the second side plates is provided with evenly distributed triangular grooves. The second side plates are all arranged between the first side plates.

[0011] Preferably, a driven gear is fixedly connected to one end of the first rotating shaft near the base on one side, and the driven gear is connected to a driving gear via a chain. A servo motor is fixedly connected to the middle of the base, and the driving end of the servo motor is fixedly connected to the driving gear.

[0012] Preferably, air boxes are fixedly connected to both sides of the top center of the base, connecting pipes are fixedly connected to the top center of each air box, ventilation ducts are fixedly connected to the top of each connecting pipe, the ventilation ducts are fixedly connected to the support frame through fixing blocks, and multiple evenly distributed air outlet hoods are fixedly connected to the sides of the ventilation ducts that are close to each other, and filters are fixedly connected inside each air outlet hood, and the filters are all made of tungsten material.

[0013] Working Principle: In actual use, the first side plate receives the steel rod transmitted from the upper-level transmission mechanism. The steel rod can be engaged in the first triangular groove of the first side plate. Because a protective pad is installed in the triangular groove, and the protective pad is made of tungsten material, it can withstand high temperatures, preventing rigid contact between the steel rod and the first side plate. This would prevent deformation of the incompletely cooled steel, affecting the quality of the steel product. The operator controls a servo motor, whose drive end drives the active gear to rotate. The active gear and the driven gear are connected by a chain, allowing them to rotate synchronously. When rotating, it drives the first shaft connected to the driven gear. With the cooperation of the first connecting plate, the second shaft and the second bearing seat can rotate synchronously. Through the cooperation between the first connecting plate, the first shaft, and the second shaft, the rocker arm function can be achieved, enabling the second side plate to move upward. When the triangular groove on the second side plate moves below the steel bar, the steel bar enters the triangular groove on the second side plate. When the second side plate begins to move downward, the steel bar enters the second triangular groove on the first side plate. This process repeats, enabling the steel bar to move on the cooling bed. During the movement of the steel bar, the bellows start working, drawing out the external... Compressed air from the ambient environment is blown into the ventilation duct through a connecting pipe. The compressed airflow from the air box is then evenly directed towards the steel through the exhaust hood. Because the base has evenly distributed ventilation windows, the airflow passing through the cooling bed accelerates the airflow near the steel, facilitating rapid cooling. As the temperature near the steel decreases, the lubricating oil in the bearing housing is not affected by high temperatures, preventing rapid melting and reduced lubrication. Simultaneously, a temperature sensor installed in the maintenance chamber transmits the temperature signal to the controller via a wireless network. Upon receiving the signal, the controller transmits it again via the wireless network. By accessing the internet cloud, staff can rationally schedule maintenance and repair work based on the temperature data. During maintenance, staff can enter the maintenance chamber via a ramp. Once the temperature inside the chamber is suitable, the temperature sensor transmits a signal to the controller, which then sends a signal to the stepper motor and fan. Upon receiving the signal, the fan rotates, and the stepper motor drives the second connecting plate to rotate. With the cooperation of the fixed frame, fixed pin, connecting shaft, and connecting rod, the fan can rotate in all directions within the fixed frame, ensuring even airflow into the maintenance chamber and facilitating the maintenance work.

[0014] This invention provides a cooling system for the moving gears of a cooling bed. It has the following beneficial effects:

[0015] 1. This invention controls the airbox, where an air pump compresses ambient air and blows it into the ventilation duct through a connecting pipe. The compressed air is then evenly directed towards the steel through an exhaust hood. Because the base has evenly distributed ventilation windows, the airflow near the steel accelerates as it passes through the cooling bed, facilitating rapid cooling. As the temperature near the steel decreases, the lubricating oil in the bearing housing is not affected by the high temperature, preventing rapid melting and reduced lubrication. Simultaneously, a protective pad made of tungsten metal is installed in the triangular groove to prevent the hot steel from directly contacting the cooling bed's moving teeth and support, thus avoiding equipment deformation and steel scraping. This increases the equipment's lifespan and collection speed. Furthermore, a filter screen inside the exhaust hood filters impurities from the airflow, preventing them from adhering to the hot steel and affecting its quality.

[0016] 2. This invention uses a temperature sensor installed inside the maintenance chamber to transmit the temperature signal from the chamber to the controller via a wireless network. Upon receiving the signal, the controller transmits it to the internet cloud via the same wireless network. Using the temperature data from the internet cloud, staff can rationally schedule maintenance operations. During maintenance, staff can enter the maintenance chamber via a ramp. Once the temperature inside the chamber is suitable, the temperature sensor transmits the signal to the controller, which then sends the signal to the stepper motor and fan. Upon receiving the signal, the fan rotates, and the stepper motor drives the second connecting plate to rotate. With the cooperation of the fixed frame, fixed pin, connecting shaft, and connecting rod, the fan can rotate in all directions within the fixed frame, ensuring even airflow into the maintenance chamber and facilitating maintenance work.

[0029] Example:

[0030] like Figure 1-10As shown, this embodiment of the invention provides a cooling system for the moving gears of a cooling bed, including a base 1. Multiple evenly distributed ventilation windows 6 are fixedly connected to the center of one side of the base 1. A maintenance chamber 3 is located at the center of the top of the base 1. A base 11 is fixedly connected to one side of the bottom of the maintenance chamber 3. Protective covers 32 are fixedly connected to the center of the front and rear side walls of the maintenance chamber 3. Fixing seats 35 are fixedly connected to the upper center of the front and rear side walls of the maintenance chamber 3. The fixing seats 35 are all located within the center of the protective covers 32. Stepper motors 36 are fixedly connected to the center of the side of the fixing seats 35 that are close to each other. The drive ends of the stepper motors 36 are all fixedly connected to the center of the side walls. A second connecting plate 43 is fixedly connected. A connecting shaft 42 is rotatably connected to the end of the second connecting plate 43 away from the stepper motor 36. A fan 40 is fixedly connected to the end of the connecting shaft 42 away from the second connecting plate 43. When the stepper motor 36 receives a signal, it can drive the second connecting plate 43 to rotate. With the cooperation of the fixed frame 41, the fixed pin 39, the connecting shaft 42 and the connecting rod 37, the fan 40 can rotate in all directions within the fixed frame 41. This allows the fan 40 to deliver air evenly into the maintenance chamber 3, reducing the temperature inside the maintenance chamber 3 and facilitating the maintenance work of the staff.

[0031] Fixed pins 39 are symmetrically arranged on the outer periphery of the fan 40. The ends of the fixed pins 39 that are far apart from each other are rotatably connected to the fixed frame 41. The top and bottom middle parts of the fixed frame 41 are rotatably connected to the connecting rods 37. The ends of the connecting rods 37 that are far away from the fixed frame 41 are fixedly connected to the middle of both sides of the fixed seat 35. The connecting rods 37 are all L-shaped. By setting the fixed pins 39, the firmness of the fan 40 can be increased, and the stability of the fan 40 during rotation can be guaranteed. By setting the connecting rods 37 to be L-shaped, it is beneficial to improve the connection between the fixed seat 35 and the fixed frame 41. At the same time, the lower part of the connecting rods 37 and the fixed frame 41 can rotate relative to each other, which can facilitate the fan 40 to rotate in all directions, which is conducive to the fan 40 to deliver air evenly and to assist the staff in maintenance work.

[0032] An inclined platform 2 is fixedly connected to the other side of the maintenance chamber 3. Multiple evenly distributed ventilation slots 33 are provided on the side of the protective cover 32.

The temperature sensor 34 installed in the maintenance chamber 3 can transmit the temperature signal in the maintenance chamber 3 to the controller 31 through a wireless network. After receiving the signal from the temperature sensor 34, the controller 31 transmits the signal to the Internet cloud through the wireless network. The staff can reasonably arrange the staff to carry out maintenance through the temperature data in the Internet cloud.

[0033] A support frame 9 is fixedly connected to the top of the base 11. Slide rails 7 are fixedly connected to the four corners of the top of the support frame 9.

At the same time, the protective pads 38 are set in the triangular grooves 14. The protective pads 38 are made of tungsten metal. Tungsten is a steel gray or silvery white metal with high hardness, high melting point and resistance to air corrosion at room temperature. It can prevent high-temperature steel from directly contacting the cold bed moving gear and support, which would cause deformation of the equipment and help increase the service life of the equipment.

[0034] Support blocks 17 are fixedly connected to the four corners of the top center of the base 11. A first bearing seat 24 is fixedly connected to the top center of each support block 17. A first rotating shaft 30 is rotatably connected to the side of the first bearing seat 24 near the center of the base 11. A first connecting plate 23 is fixedly connected to the end of the first rotating shaft 30 away from the first bearing seat 24. A second rotating shaft 26 is fixedly connected to the upper part of the first connecting plate 23. A second bearing seat 27 is rotatably connected to the end of the second rotating shaft 26 away from the first connecting plate 23. An oil inlet pipe 44 is fixedly connected to the middle of one side of the first bearing seat 24 and the second bearing seat 27. A valve 45 is provided in the middle of the outer periphery of the oil inlet pipe 44. By setting the first bearing seat 24 and the second bearing seat 27, the smoothness of the rotation of the first rotating shaft 30 and the second rotating shaft 26 can be ensured. By opening the valve 45 on the oil inlet pipe 44, the operator can add lubricating oil into the first bearing seat 24 and the second bearing seat 27, which can ensure the rotational stability of the shaft.

[0035] The second bearing seat 27 is fixedly connected to both sides of the support plate 22 on the side near the middle of the base 11.

By setting the support plate 22, vertical plate 25 and horizontal plate 12, the overall firmness of the second side plate 13 can be ensured, which is conducive to ensuring the normal operation of the second side plate 13. At the same time, with the assistance of the first side plate 4, the purpose of collecting steel can be achieved.

[0036] A driven gear 18 is fixedly connected to one end of the first rotating shaft 30 on one side near the base 1. The driven gear 18 is connected to the driving gear 20 through the chain 19.

With the cooperation of the driving gear 20, the driven gear 18 and the chain 19, the servo motor 21 can provide power to the equipment, so that the equipment can operate stably.

[0037] A bellows 16 is fixedly connected to both sides of the top center of the base 11. A connecting pipe 15 is fixedly connected to the top center of the bellows 16. A ventilation duct 8 is fixedly connected to the top of the connecting pipe 15. The ventilation duct 8 is fixedly connected to the support frame 9 through a fixing block 10. Multiple evenly distributed air outlet hoods 29 are fixedly connected to the sides of the ventilation ducts 8 that are close to each other. A filter screen 28 is fixedly connected inside the air outlet hood 29. The filter screens 28 are all made of tungsten material. During the movement of the steel, the bellows 16 start to work, compressing the air from the outside environment and blowing it into the ventilation duct 8 through the connecting pipe 15. Then, the air compressed by the bellows 16 is evenly blown onto the steel through the air outlet hoods 29. When the airflow passes through the cooling bed, it will accelerate the airflow near the steel, which is conducive to the rapid cooling of the steel. At the same time, the filter screen 28 is set inside the air outlet hood 29, which can filter some impurities in the airflow and prevent impurities from adsorbing on the high-temperature steel, thus affecting the quality of the steel. The filter screen 28 is made of tungsten metal, which can withstand high temperatures and can increase the service life of the filter screen 28.
