Description

Technical Field

[0001] The invention relates to a steel-running prevention system for a steel-rolling workshop of a steel-making plant, and in particular to a steel-running prevention system for a steel-rolling workshop of a steel-making plant. Background Art

[0002] In the rolling mill of a steel mill, steel should be continuously rolled and deformed according to the established rolling route and process requirements, under the guidance and action of equipment such as rollers and guide devices. If the steel accidentally deviates from the normal rolling route, it is called "steel running", which causes material waste and may endanger the safety of operators and cause work-related accidents.

[0003] Because the steel on the production line is conveyed at a very high speed and is at a high temperature, it is necessary to urgently cut off the conveyed steel strip to reduce losses when steel slips. The existing technology requires manual and timely operation of the flying shear to cut off the front and rear steel strips to facilitate the restoration of normal conveying of subsequent steel strips. However, manual operation is affected by many factors such as worker experience and status, and there are major safety hazards. In addition, the existing flying shear structure will block the subsequent steel strips during the cutting process, which will hinder the conveying of the subsequent steel strips and easily deviate from the normal conveying track under the action of conveying inertia.

[0004] To this end, technical personnel in this field have proposed a steel-leaking prevention system for the rolling mill workshop of a steel mill. A flying shear operating structure is set on the rolling production line, which can automatically start in time according to the status of the production line, instead of manual labor to promptly reflect and safely handle the steel leakage problem, thereby reducing production losses. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a system for preventing steel from running away in a rolling mill of a steelmaking plant. A movable pressure roller is arranged at a certain distance above the conveying track to sense the movement changes of the steel strip, thereby triggering the cutting blade arranged on the inner side of the roller to advance and follow the rotation of the roller to cut the steel strip, thereby avoiding the problem that the existing flying shear that moves vertically and requires a return stroke easily obstructs the moving steel strip. In addition, a demolition hammer is provided to ensure the separation of the front and rear ends of the steel strip, which helps to break the steel strip at the cutting point to reduce losses.

[0006] To achieve the above objectives, the present invention is implemented through the following technical scheme: a steel mill rolling shop anti-steel escape system, including a conveyor track and rollers, the conveyor track is provided with rollers to roll the steel strip, the upper and lower rollers squeeze the steel strip toward the middle to achieve extrusion molding of the steel strip, and the molded steel strip continues to move along the conveyor track to the winding end.

[0007] However, steel strip rolling accidents may occur in the existing steel strip rolling process. When an accident occurs, experienced workers are required to operate the flying shears in time to cut off the front and rear steel strips, and throw out the leaked steel parts to ensure that the subsequent steel strips continue to work, reduce production losses and avoid safety hazards caused by steel slippage to workers. However, this manual operation is extremely dependent on manual operation experience, and disordered steel slippage poses a huge safety hazard. The accident losses are difficult to control and can easily cause greater safety accidents. Therefore, more intelligent automatic risk elimination equipment is needed to assist production.

[0008] In order to help avoid the risk of accidents, technical personnel in this field have installed an intelligently controlled flying shear mechanism on the steel rolling production line. The flying shear mechanism includes a pressure roller, which is tightly arranged above the conveying track behind the rolling roller. The height between the pressure roller and the conveying track is suitable for the passage of the steel strip. When a steel strip runs away, the steel strip flies out of the predetermined route on the conveying track under the action of inertia and causes a thrust to the pressure roller, causing the pressure roller to displace a certain distance upward. The occurrence of this displacement automatically triggers the flying shear mechanism in time to cut the steel strip.

[0009] A cutting blade is slidingly arranged on the inner side of the roller, and a driving member is arranged on the inner side of the roller corresponding to the cutting blade. The pressure roller is electrically connected to the driving member. Under the action of steel running, the pressure roller advances and connects the driving member control power supply. The driving member controls the cutting blade to advance and protrude from the roller. As the two rollers rotate, the steel strip is squeezed and cut in time within one rotation cycle. As the rollers rotate, the cutting blade will not hinder the moving steel strip, and can automatically start the cutting blade to cut the steel strip in time by sensing the occurrence of steel running.

[0010] The steel strip cut by squeezing the two cutting blades may not necessarily be disconnected at the front and back ends. Therefore, a demolition hammer is provided on the side of the pressure roller close to the rolling roller. The side of the demolition hammer is meshed with a retarder gear. As the pressure roller triggers the driving member, the demolition hammer is simultaneously triggered to fall. Under the action of the retarder gear, the steel strip moves and hits the cutting position of the steel strip, thereby ensuring that the cut steel strip is disconnected at the front and back ends, thereby preventing the inertia of the running steel section from affecting the normal production of subsequent steel strips.

[0011] Preferably, columns are symmetrically fixed on both sides of the conveying track, the pressure roller is slidably arranged between the two columns parallel to the conveying track, a first slider is slidably arranged inside the column, and an electrical spring is arranged between the first slider and the column corresponding to the driving member.

[0012] The distance between the pressure roller and the upper surface of the conveying track is adjusted so that the normally rolled steel strip can pass smoothly. When a steel slip accident occurs, the steel strip leaves the conveying track under the action of inertia and exerts a thrust on the pressure roller. The pressure roller moves upward along the column and connects the control circuit of the drive component, and then the driving component drives the cutting blade to advance the steel strip, so that the cutting blade of the protruding roller cuts the steel strip as it rolls.

[0013] Preferably, a feed groove is provided on the side of the roller, and the cutting blade is slidably engaged in the inner side of the feed groove. A first spring is also tightly arranged on the side of the cutting blade away from the feed end, and the end of the first spring away from the cutting blade is meshed with the driving member.

[0014] The driving member drives the cutting blade to cut the steel strip along the feed groove and protrude from the roller through meshing action. The first spring provides the cutting blade with a tight cutting pressure on the steel strip. At the same time, when encountering obstacles that prevent smooth cutting, the cutting blade can be protected by compressing the first spring.

[0015] Preferably, a carry-in cross plate is also slidably provided on the inner side of the roller, and a first rack is symmetrically fixed on the side of the carry-in cross plate. The carry-in cross plate is meshed and connected with the driving member through the first rack on one side, and the cutting blade is pressed and driven by the carry-in cross plate. While providing sufficiently large cutting pressure, it can also avoid severe structural wear caused by excessive movement between the driving member and the carry-in cross plate. After the cutting blade moves into place, it is disengaged from the driving member through the deformation of the first rack.

[0016] Preferably, a first sleeve is fixedly provided at one end of the first rack on both sides away from the carry horizontal plate, and a second spring is tightly provided on the inner side of the first sleeve corresponding to the first rack. The second spring is tightly installed on the inner side of the first gear through the first sleeve, and the first rack is pressed against the driving member by the second spring to maintain the meshing state.

[0017] Preferably, a fixing rod is fixedly connected between the first racks on both sides, and the first sleeve is fixedly connected to the fixing rod extending to the end of the first rack away from the carry cross plate, and a mounting structure for the first sleeve is formed between the two first racks through the fixing rod, and the deformation capacity of the ends of the two first racks is not affected.

[0018] A second sleeve is also fixedly connected to the inner side of the first rack corresponding to the second spring, and the second spring is stably and tightly mounted against the inner wall of the first rack through the second sleeve.

[0019] Preferably, one end of the second spring extending into the inner side of the first sleeve is fixedly connected to a second slider, and a side surface of the second slider is fixedly connected to a protrusion. The second slider is slidably engaged with the inner side of the first sleeve through the protrusion. The second slider slidably arranged on the inner side of the first sleeve can adjust the elastic force of the second spring on the first rack, so that while ensuring that the first spring has a sufficiently large tightening force on the cutting blade, the first rack can be disengaged from the meshing drive of the driving member by compressing the second spring.

[0020] Preferably, a fixing block is fixedly connected to the middle position of the inner side of the first sleeve, and a tightening bolt is penetrated through the side of the fixing block and the bearing is provided with the tightening bolt, and the tightening bolt penetrates the second slider and is threadedly connected thereto. The tightening bolt drives the second slider to be slidably installed inside the first sleeve through the threaded connection relationship between the tightening bolt and the second slider, thereby changing the position of the starting end of the second spring, thereby achieving the purpose of changing the magnitude of the elastic force applied by the second spring to the first rack.

[0021] Preferably, a knob is inserted into the side of the first sleeve, and the knob is meshed with the tightening bolt through a bevel gear. The meshing directions of the second sliders on both sides and the tightening bolt are opposite. Rotating the knob drives the tightening bolt to rotate, and the rotating tightening bolt drives the two second sliders to move in opposite directions, while equidistantly changing the elastic force of the two second springs on the first rack.

[0022] Preferably, slide rails are fixedly connected to both sides of the conveying track, and a second rack is provided on the inner side of the slide rail through a retarder gear. The demolition hammer is fixedly connected to the second rack. When the pressure roller advances due to steel running, the advancement of the demolition hammer is simultaneously triggered. Under the meshing control of the retarder gear, the demolition hammer contacts the cutting point of the steel strip at a certain speed to help disconnect the steel strips on both sides, thereby ensuring that the subsequent steel strips will not be affected by the inertia of the running steel and leave the conveying track.

[0023] A limit pin is hingedly provided on one side of the slide rail close to the pressure roller corresponding to the second rack. The pressure roller moves upward to push the limit pin to deflect, so that the second rack is separated from the limit of the limit pin and slides downward under the action of gravity.

[0024] The present invention discloses a steel mill rolling workshop anti-steel escape system, which has the following beneficial effects:

[0025] 1. The anti-slip system of the steel mill's rolling workshop is to set a pressure roller at a certain height above the conveyor track to sense the slipping of the steel strip, and trigger the cutting blade set on the inner side of the roller to roll and cut the steel strip. On the one hand, when the slipping of the steel strip occurs, the steel strip will exert a force on the pressure roller under the action of inertia to push it to move, and the carry control circuit of the cutting blade is connected through the displacement of the pressure roller. This method has higher accuracy and stronger stability than manual control. On the other hand, the cutting blade set on the inner side of the roller cuts as the steel strip rolls, and will not hinder the continuous movement of the steel strip. Combined with the associated demolition hammer, it ensures that the two ends of the cut steel strip are disconnected, avoiding the problem of incomplete cutting causing the subsequent steel strip to be deflected by the inertia of the slipping steel section.

[0026] 2. The steel mill's rolling mill workshop anti-slip system has a pressure roller that is set at a certain height above the conveyor track through a sliding column. When a steel strip slips above the conveyor track, the steel strip will leave the conveyor track and exert a thrust on the pressure roller to make it move forward. The moved pressure roller connects to the control circuit of the driving part, thereby driving the cutting blade set on the inner side of the roller to move forward and protrude from the roller. The cutting blade protruding from the roller squeezes and cuts the steel strip as the roller rotates, and the rolling cutting blade will not hinder the conveyed steel strip, thus avoiding the cutting blade that moves up and down in the prior art from affecting the normal conveying of the steel strip during the cutting process.

[0027] 3. The steel mill's rolling mill workshop has an anti-slip steel system. The cutting blade is pressed forward by the first spring against the advancement cross plate. When the pressure roller is pushed forward by the slipping steel strip, the drive circuit is connected, and the advancement cross plate pushes the cutting blade to slide forward along the advancement groove. Under the action of the first spring, the cutting blade is pressed against the steel plate with a certain pressure for cutting. While ensuring the cutting effect on the steel strip, the cutting blade can be protected by compressing the first spring when encountering too great an obstacle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present invention discloses a steel-running prevention system for a steel-making plant rolling workshop;

[0039] According to the attached Figure 1 As shown, it includes a conveying track 1 and rollers 2. The rollers 2 are arranged on the conveying track 1 to roll the steel strip. The upper and lower rollers 2 squeeze the steel strip toward the middle to achieve extrusion forming of the steel strip. The formed steel strip continues to move along the conveying track 1 to the winding end. Usually, a manually controlled flying shear is installed on the conveying track 1 to manually cut the steel strip to reduce losses when a steel running accident occurs.

[0040] However, steel strip rolling accidents may occur in the existing steel strip rolling process. When an accident occurs, experienced workers are required to operate the flying shears in time to cut off the front and rear steel strips, and throw out the leaked steel parts to ensure that the subsequent steel strips continue to work, reduce production losses and avoid safety hazards caused by steel slippage to workers. However, this manual operation is extremely dependent on manual operation experience, and disordered steel slippage poses a huge safety hazard. The accident losses are difficult to control and can easily cause greater safety accidents. Therefore, more intelligent automatic risk elimination equipment is needed to assist production.

[0041] According to the attached Figure 1 , Attachment Figure 2 Attached Figure 3 and attached Figure 4 As shown, in order to help avoid the risk of accidents, technicians in this field set up an intelligently controlled flying shear mechanism 3 on the steel rolling production line. The flying shear mechanism 3 includes a pressure roller 301. The pressure roller 301 is tightly arranged above the conveying track 1 behind the rolling roller 2. The height between the pressure roller 301 and the conveying track 1 is suitable for the passage of the steel strip. When the steel strip runs away, the steel strip flies out of the predetermined route on the conveying track 1 under the action of inertia and causes a thrust to the pressure roller 301, causing the pressure roller 301 to move upward a certain distance. The occurrence of this displacement automatically triggers the flying shear mechanism 3 in time to cut the steel strip.

[0042] A cutting blade 302 is slidingly arranged on the inner side of the roller 2, and a driving member 303 is arranged on the inner side of the roller 2 corresponding to the cutting blade 302. The pressure roller 301 is electrically connected to the driving member 303. Under the action of steel running, the pressure roller 301 advances to connect the driving member 303 to control the power supply, and the driving member 303 controls the cutting blade 302 to advance and protrude from the roller 2. As the two rollers 2 rotate, the steel strip is squeezed and cut in time within one rotation cycle. As the roller 2 rotates, the cutting blade 302 that cuts will not hinder the moving steel strip, and can automatically start the cutting blade 302 to cut the steel strip in time by sensing the occurrence of steel running.

[0043] The steel strip cut by squeezing with two cutting blades 302 may not necessarily be disconnected at the front and back, so a demolition hammer 4 is also provided on the side of the pressure roller 301 close to the rolling roller 2, and the side of the demolition hammer 4 is meshed and connected with a retarder gear 5. As the pressure roller 301 triggers the driving member 303, the demolition hammer 4 is simultaneously triggered to fall, and under the action of the retarder gear 5, the steel strip moves and hits the cutting position of the steel strip, ensuring that the cut steel strip is disconnected at the front and back, thereby avoiding the inertia of the running steel section affecting the normal production of subsequent steel strips.

[0044] According to the attached Figure 4 As shown, columns 6 are symmetrically fixed on both sides of the conveying track 1, and the pressure roller 301 is slidably set between the two columns 6 parallel to the conveying track 1. A first slider 7 is slidably set on the inner side of the column 6, and an electrical spring 8 is set between the first slider 7 and the column 6 corresponding to the driving member 303.

[0045] The distance between the pressure roller 301 and the upper surface of the conveying track 1 is adjusted so that the normally rolled steel strip can pass smoothly. When a steel running accident occurs, the steel strip leaves the conveying track 1 under the action of inertia and exerts a thrust on the pressure roller 301. The pressure roller 301 moves upward along the column 6 and connects the control circuit of the driving member 303, and then drives the cutting blade 302 to advance the steel strip through the driving member 303. The cutting blade 302 of the protruding roller 2 cuts the steel strip as it rolls.

[0046] According to the attached Figure 5 As shown, a feed groove 9 is provided on the side of the roller 2, and the cutting blade 302 is slidably engaged in the inner side of the feed groove 9. A first spring 10 is also tightly arranged on the side of the cutting blade 302 away from the feed end, and the end of the first spring 10 away from the cutting blade 302 is meshed and connected with the driving member 303.

[0047] The driving member 303 drives the cutting blade 302 to protrude from the roller 2 along the feed groove 9 to cut the steel strip through the meshing action. The first spring 10 provides the cutting blade 302 with a tight cutting pressure on the steel strip. At the same time, when encountering obstacles that prevent smooth cutting, the cutting blade 302 can be protected by compressing the first spring 10.

[0048] A carry-in cross plate 11 is also slidably provided on the inner side of the roller 2, and a first rack 12 is symmetrically fixed on the side of the carry-in cross plate 11. The carry-in cross plate 11 is meshed and connected with the driving member 303 through the first rack 12 on one side, and the cutting blade 302 is pressed and driven by the carry-in cross plate 11. While providing sufficiently large cutting pressure, it can also avoid excessive movement between the driving member 303 and the carry-in cross plate 11 to cause serious wear of the structure. After the cutting blade 302 moves into place, it is disengaged from the driving member 303 through the deformation of the first rack 12.

[0049] According to the attached Figure 6 As shown, a first sleeve 13 is fixedly provided at one end of the first racks 12 on both sides away from the carry horizontal plate 11, and a second spring 14 is provided on the inner side of the first sleeve 13 corresponding to the first rack 12 to press against it. The second spring 14 is installed to press against the inner side of the first gear 12 through the first sleeve 13, and the first rack 12 is pressed against the driving member 303 by the second spring 14 to maintain the meshing state.

[0050] A fixing rod 15 is fixedly connected between the first racks 12 on both sides, and the first sleeve 13 is fixedly connected to the fixing rod 15 and extends to one end of the first rack 12 away from the carry cross plate 11. The fixing rod 15 forms a mounting structure for the first sleeve 13 between the two first racks 12 without affecting the deformation capacity of the ends of the two first racks 12.

[0051] A second sleeve 16 is also fixedly connected to the inner side of the first rack 12 corresponding to the second spring 14 , and the second spring 14 is stably and tightly mounted against the inner wall of the first rack 12 through the second sleeve 16 .

[0052] One end of the second spring 14 extending into the inner side of the first sleeve 13 is fixedly connected to a second slider 17, and a protrusion 18 is fixedly connected to the side of the second slider 17. The second slider 17 is slidably clamped to the inner side of the first sleeve 13 through the protrusion 18. The second slider 17 slidingly arranged on the inner side of the first sleeve 13 can adjust the elastic force of the second spring 14 on the first rack 12, so that while ensuring that the first spring 10 has a sufficiently large tightening force on the cutting blade 302, the first rack 12 can be disengaged from the meshing drive of the driving member 303 by compressing the second spring 14.

[0053] A fixing block 19 is fixedly connected to the middle position of the inner side of the first sleeve 13, and a tightening bolt 20 is penetrated through the side surface of the fixing block 19 and the bearing is provided. The tightening bolt 20 penetrates the second slider 17 and is threadedly connected thereto. The tightening bolt 20 drives the second slider 17 to slide and install inside the first sleeve 13 through the threaded connection relationship between the tightening bolt 20 and the second slider 17, thereby changing the position of the starting end of the second spring 14, thereby achieving the purpose of changing the elastic force applied by the second spring 14 to the first rack 12.

[0054] A knob 21 is inserted into the side of the first sleeve 13, and the knob 21 is meshed with the tightening bolt 20 through a bevel gear. The meshing directions of the second sliders 17 on both sides are opposite to the tightening bolt 20. Rotating the knob 21 drives the tightening bolt 20 to rotate, and the rotating tightening bolt 20 drives the two second sliders 17 to move in opposite directions, while equidistantly changing the elastic force of the two second springs 14 on the first rack 12.

[0055] According to the attached Figure 7 As shown, slide rails 22 are fixedly connected to both sides of the conveying track 1, and a second rack 23 is provided on the inner side of the slide rail 22 through a meshing retarder gear 5. The demolition hammer 4 is fixedly connected to the second rack 23. When the pressure roller 301 advances due to steel running, the advancement of the demolition hammer 4 is triggered at the same time. Under the meshing control of the retarder gear 5, the demolition hammer 4 contacts the cutting point of the steel strip at a certain speed to help break the steel strips on both sides, ensuring that the subsequent steel strips will not be affected by the inertia of the running steel and leave the conveying track 1.

[0056] A limit pin 24 is hingedly provided on one side of the slide rail 22 close to the pressure roller 301 corresponding to the second rack 23. The pressure roller 301 moves upward to push the limit pin 24 to deflect, so that the second rack 23 is free from the limit of the limit pin 24 and slides downward under the action of gravity.

[0057] The anti-slipping steel system of the rolling mill of the steel mill is realized by setting a pressure roller 301 at a certain height above the conveying track 1 to sense the slipping steel, and triggering the cutting blade 302 set on the inner side of the rolling roller 2 to roll and cut the steel strip. On the one hand, when the slipping steel occurs, the steel strip will exert a force on the pressure roller 301 under the action of inertia to push it to move, and the displacement of the pressure roller 301 connects the carry control circuit of the cutting blade 302. This method has higher accuracy and stronger stability than manual control. On the other hand, the cutting blade 302 set on the inner side of the rolling roller 2 cuts as the steel strip rolls, and will not hinder the continuous movement of the steel strip. Combined with the associated demolition hammer 4, it ensures that the two ends of the cut steel strip are disconnected, so as to avoid the problem of incomplete cutting causing the subsequent steel strip to be deflected by the inertia of the slipping steel section.

[0058] Furthermore, the pressure roller 301 is slidably arranged at a certain height above the conveying track 1 through the column 6. When the steel strip slips above the conveying track 1, the steel strip will leave the conveying track 1 and exert a thrust on the pressure roller 301 to make it move forward. The moved pressure roller 301 connects to the control circuit of the driving component 303, thereby driving the cutting blade 302 arranged on the inner side of the rolling roller 2 to move forward and protrude from the rolling roller 2. The cutting blade 302 protruding from the rolling roller 2 squeezes and cuts the steel strip as the rolling roller 2 rotates. The rolling cutting blade 302 will not hinder the conveyed steel strip, thereby avoiding the cutting blade 302 moving up and down in the prior art from affecting the normal conveying of the steel strip during the cutting process.

[0059] Furthermore, the cutting blade 302 is pressed forward by the first spring 10 pressed against the advancement cross plate 11. When the pressure roller 301 is pushed forward by the running steel strip, the circuit of the driving member 303 is connected, and the advancement cross plate 11 pushes the cutting blade 302 to slide forward along the advancement groove 9. Under the action of the first spring 10, the cutting blade 302 is pressed against the steel plate with a certain pressure for cutting, which ensures the cutting effect on the steel strip. When encountering too large an obstacle, the cutting blade 302 can be protected by compressing the first spring 10.
