Description

Technical Field

[0001] The invention relates to the technical field of hot rolling of steel, in particular to a steel rolling cooling bed transmission structure. Background Art

[0002] my country is a major steel producer in the world, and the steel rolling cooling bed is an important production equipment that is indispensable to the production of most steel enterprises. The moving parts of the existing steel rolling cooling bed (including counterweight) and the steel being cooled on the steel rolling cooling bed are all borne by two drive shafts with eccentric wheels. The product of all the weight and the eccentricity of the eccentric wheel is the torque that needs to be transmitted. The torque in the steel rolling cooling bed transmission structure is provided by two mutually connected and synchronized speed change transmission boxes. The steel rolling cooling bed rises and steps once for each rotation of the drive shaft. For example, in the production of 200 mm size steel, the maximum stepping distance of the steel rolling cooling bed is 160 mm, and the eccentricity of the eccentric wheel is 80 mm. At this time, the steel rolling cooling bed needs to step twice to reach the required distance. Since the stepping distance of the steel rolling cooling bed is 160 mm, Meters. If the eccentricity of the eccentric wheel is too large, the torque will increase sharply, and the steel rolling cooling bed can only step several times to reach the required step distance, which increases energy consumption; the steel rolling cooling bed transmission structure bears a large weight, and the eccentric wheel and the load-bearing wheel above it rotate and rub against each other, and the friction and lubrication of the eccentric wheel are exposed, so the eccentric wheel, the load-bearing wheel, and the transmission shaft that transmits torque are often damaged; in order to reduce the damage and failure rate, the only option is to increase the shaft diameter and transmission mechanism, which increases the weight of the steel rolling cooling bed; due to the increase in the weight of the steel rolling cooling bed and the need to work under heavy load during production, the power consumption increases and the weight of each steel rolling cooling bed is generally around 200 to 300 tons, which increases the investment cost of the enterprise. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned problems, thereby providing a rolling mill cooling bed transmission structure with a simple and reasonable structure and clear force, which reduces the weight of the rolling mill cooling bed and can realize the lifting and stepping motion of the rolling mill cooling bed while reducing the force borne by the transmission structure. Compared with existing products, the equipment weight is reduced, the operation failure rate is reduced, the energy-saving effect is significant, the enterprise equipment investment is reduced, and the green and low-carbon development of the steel industry is better.

[0004] The present invention solves the above problems by adopting the following technical solutions:

[0005] The transmission gear of the present invention is connected with the transmission gear of the present invention one end is connected with the transmission gear of the present invention, and the transmission gear of the present invention is connected with the transmission gear of the present invention to the transmission gear of the present invention.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] The present invention has essentially outstanding advantages over the traditional rolling mill cooling bed transmission structure. The structure is simple and reasonable, the driving structure is subjected to small and clear force, and the driving part does not bear weight. In this way, a motor with smaller power can be used for driving. Most of the supported weight is transmitted to the base through the arc-shaped slide base and dispersed, which reduces the weight of the rolling mill cooling bed. While reducing the force borne by the transmission structure, the lifting and stepping motion of the rolling mill cooling bed can be realized. Compared with existing products, the equipment weight is reduced, the operation failure rate is reduced, and a larger stepping distance and a larger lifting height can be designed. Since most of the weight is directly transferred to the base, the weight of the rolling mill cooling bed will not be increased and the force will not be increased. In this way, there is no need to step several times continuously to waste energy. The energy-saving effect is significant, the enterprise equipment investment is reduced, and the steel industry develops in a green and low-carbon way.

[0009] A third transmission arm is also provided on the transmission shaft, and a first counterweight is hinged on the third transmission arm.

[0010] A connecting rope is hinged on the first sliding rod, a fixed pulley is provided on one end of the highest point of the first arc top slide base, and the connecting rope passes through the fixed pulley and is hinged to the second counterweight block.

A second arc-shaped skateboard base 17 slidably connected to the second sliding rod 16 is fixedly installed on the base 2. Pulleys adapted to the first arc-shaped skateboard base 14 and the second arc-shaped skateboard base 17 are respectively installed on the bottom of the first sliding rod 13 and the second sliding rod 16. The first sliding rod 13 and the second sliding rod 16 are respectively hinged with the movable tooth beam 7.

[0021] A third transmission arm 24 is fixedly mounted on the transmission shaft 10, to which the first counterweight 18 is hingedly connected, and a connecting rope 20 is hingedly connected to the first sliding rod 13.

The first vertical beam 51 and the second vertical beam 52 are respectively welded vertically on the base 2 at intervals. The transverse connecting beam 53 is respectively welded to the middle of the first vertical beam 51 and the second vertical beam 52 to form an H-shaped structure. The first step control seat 61 and the second step control seat 62 are respectively in a side concave shape. The grooves on the first step control seat 61 and the second step control seat 62 are arc-shaped.

[0023] The movable tooth beam 7 includes a cross beam 71, and a transmission seat 72 is welded on both sides of the upper end surface of the cross beam 71. The transmission seat 72 is hinged to the steel rolling cooling bed 1 respectively.

The first step control wheel 81 and the second step control wheel 82 are respectively installed on the first step control seat 61 and the second step control seat 62. The first step control wheel 81 and the second step control wheel 82 respectively make circular motion along the arc grooves on the first step control seat 61 and the second step control seat 62. The diameter of the circle formed by the circular motion of the first step control wheel 81 and the second step control wheel 82 is the stepping distance of the steel rolling cooling bed 1. The first step control wheel 81 is hinged to the second sliding rod 16. The connecting seat 73 hinged to the first sliding rod 13 is welded on the lower bottom surface of the cross beam 71. The steel rolling cooling bed 1 is driven to rise and fall by the movable tooth beam 7 to realize the stepping motion.

[0024] Second embodiment: When a stepping control wheel is welded on the lower bottom surface of the crossbeam of the movable tooth beam 7, two connecting seats 73 are welded on both sides of the lower bottom surface of the crossbeam 71, and the two connecting seats 73 are respectively hinged to the first sliding rod 13 and the second sliding rod 16.

The first step control seat 61 and the second step control seat 62 limit the steel rolling cooling bed 1 to prevent the steel rolling cooling bed 1 from moving too far left and right.

[0025] The working principle of this device is as follows: the power output by the motor 3 is transmitted to the transmission rod 9 through the output shaft of the reduction gear box 4, and drives the transmission rod 9 to make a circular motion, and the transmission rod 9 drives the transmission arm and the transmission shaft 10 to move, thereby causing the first connecting rod 12 to drive the first sliding rod 13 and the second sliding rod 16 to slide on the first arc-shaped skateboard base 14 and the second arc-shaped skateboard base 17, and the first sliding rod 13 and the second sliding rod 16 drive the rolling cooling bed 1 to rise and fall through the movable tooth beam 7 to achieve stepping; when the first sliding rod 13 and the second sliding rod 16 slide toward the highest point of the first arc-shaped skateboard base 14 and the second arc-shaped skateboard base 17 respectively, the third transmission arm 24 is driven downward by the first counterweight block 18, and the first sliding rod 13 is driven by the second counterweight block 19 Slide toward the highest point of the first curved skateboard base 14 to achieve the effect of saving effort; at this time, the first step control wheel 81 and the second step control wheel 82 make circular motions along the first step control seat 61 and the second step control seat 62 respectively. The first step control seat 61 and the second step control seat 62 can prevent the steel rolling cooling bed 1 from moving too far left and right during the stepping process and play a limiting role, and at the same time can control the stepping distance of the steel rolling cooling bed 1; when the first sliding rod 13 and the second sliding rod 16 slide toward the lowest point of the first curved skateboard base 14 and the second curved skateboard base 17 respectively, the gravity of the first counterweight block 18 and the second counterweight block 19 are offset by the gravity of the steel rolling cooling bed 1 itself and the gravity of the steel, thereby reducing the output power of the motor 3.

[0026] The present invention has essentially outstanding advantages over the traditional rolling mill cooling bed 1 transmission structure. The structure is simple and reasonable, the driving structure is subjected to small and clear force, and the driving part does not bear weight. In this way, a motor 3 with smaller power can be used for driving. Most of the supported weight is transmitted to the base 2 through the arc-shaped slide base and dispersed, which reduces the weight of the rolling mill cooling bed 1. While reducing the force borne by the transmission structure, the lifting and stepping motion of the rolling mill cooling bed 1 can be realized. Compared with existing products, the equipment weight is reduced, the operation failure rate is reduced, and a larger stepping distance and a larger lifting height can be designed. Since most of the weight is directly transferred to the base 2, the weight of the rolling mill cooling bed 1 will not be increased and the force will not be increased. In this way, there is no need to step continuously several times to waste energy. The energy-saving effect is significant, the enterprise equipment investment is reduced, and the steel industry develops in a green and low-carbon manner.
