Description

Technical Field

[0001] This invention belongs to the technical field of metallurgical steel ingot conveying equipment, specifically relating to a non-impact conveying device and method for steel ingots, which is suitable for automated and stable transfer, non-impact material dropping, and continuous roller conveying of high-temperature steel ingots after tapping from the heating furnace. Background Technology

[0002] In the metallurgical steel ingot forging and rolling production process, after the steel ingot is heated in the heating furnace, it needs to be transferred to the roller conveyor line by the conveying equipment, and then transported to the subsequent processing station by the roller conveyor. Multiple steel ingot heating furnaces are set up in parallel in front of a roller conveyor line. The outlet height of the multiple steel ingot heating furnaces is different. The steel ingot is transported to the furnace mouth by the high temperature resistant roller conveyor in the furnace, and falls onto the roller conveyor in front of the furnace by gravity. The maximum drop is about 1 meter. Figure 5 This is a schematic diagram of the existing furnace and the furnace front roller conveyor. In the existing technology, a furnace front roller conveyor is set in front of the furnace opening. Since there is a roller conveyor pit below the furnace front roller conveyor, it is not possible to set up a steel ingot receiving device inside the roller conveyor. In order to facilitate the control of rotation and stopping, the roller 11 of the furnace front roller conveyor is supported by a support frame 17 to support the bearing seat 15 at the end of the roller. Each roller end is equipped with a small motor 16 to drive the roller 11 to rotate. Multiple small motors 16 are controlled by a controller to rotate synchronously.

[0003] Existing technologies have several shortcomings in actual production: First, traditional conveying mechanisms suffer from severe rigid contact during material unloading. Given the large weight of the steel ingots, the falling process easily generates impact loads on the roller conveyor rollers, leading to roller deformation, roller surface wear, and bearing damage over time. This significantly reduces equipment lifespan and increases maintenance costs and downtime. Second, after completing the ingot unloading operation, the conventional conveying structure has a single exit method, making it prone to rubbing and interference with the roller conveyor and steel ingots. This can easily cause scratches on the bottom of the ingots, equipment jamming, and affect production continuity. Third, the furnace-front operating conditions are characterized by high temperatures and strong radiant heat. Existing equipment lacks effective heat insulation structures, leaving guide rails, drives, and lifting mechanisms in a high-temperature environment, prone to component deformation, transmission failure, and aging and damage to electrical components. Fourth, traditional equipment exhibits strong independence in each action, poor linkage with the heating furnace and roller conveyor system, low positioning accuracy, insufficient automation, and low production stability and efficiency, failing to meet the demands of large-scale, continuous, and high-precision steel ingot production.

[0004] Therefore, there is an urgent need to design a steel ingot conveying device and method that is structurally stable, can achieve impact-free material dropping, interference-free return, high temperature resistance, and high degree of automation, in order to solve the technical problems of impact damage, interference jamming, high temperature damage, and poor linkage in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a non-impact steel ingot conveying device and method, which solves the technical problems of existing steel ingot conveying equipment, such as large impact during material drop, easy interference during retraction, easy damage at high temperatures, poor automation linkage, and high equipment failure rate. It achieves smooth, non-impact, interference-free, automated, and continuous operation of the entire process of steel ingot receiving, translation, dropping, retraction, resetting, and roller conveying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A non-impact conveying device for steel ingots includes paired guide rails, a movable trolley, a lifting device, steel ingot receiving components, a counterweight, supporting columns, and a conveying roller conveyor composed of several rollers. One end of each guide rail is fixed to an embedded part of the steel structure in front of the heating furnace, and the other end of the guide rail is supported by the supporting columns, the bottom of which is fixed to the ground with anchor bolts. The movable trolley is slidably mounted on the paired guide rails. The lifting device is fixedly installed on the movable trolley, and its output end is connected to the steel ingot receiving components, which are paired shovel-type structures. Each steel ingot receiving component is narrower than the gap between the rollers of the conveyor and is located directly above the gap. The counterweight is configured to cooperate with the output end of the steel ingot receiving component or the lifting device to balance the lifting load. When the device performs the conveying operation, the controller stops the conveyor rollers in front of the furnace, and the ingot receiving component moves to the furnace opening to receive the ingot. The moving trolley moves the ingot receiving component carrying the ingot horizontally to directly above the conveyor rollers. The lifting device drives the ingot receiving component to slowly descend, and the ingot receiving component descends into the corresponding gap between the rollers, so that the ingot is smoothly placed on the top surface of the rollers. After the weight of the ingot is completely borne by the conveyor rollers, the ingot receiving component continues to descend slightly, so that the ingot receiving component separates from the ingot. Then the moving trolley drives the ingot receiving component to move horizontally backward and completely detach from the bottom of the ingot. After it moves into place, the lifting device drives the ingot receiving component to rise and reset. Finally, the conveyor rollers rotate to complete the continuous conveying of the ingot. The thickness of the shovel head is less than the gap width between adjacent rollers, so that there is no mechanical interference when the shovel head retracts horizontally within the roller height range, realizing the steel ingot placement without impact and the exit operation without interference; Furthermore, the guide rail is made of heavy-duty I-beam steel or high-temperature resistant linear guide rail, and the surface of the guide rail is hardened by quenching, giving it wear resistance, deformation resistance and high-temperature resistance. Furthermore, the mobile trolley includes a trolley body, traveling wheels, and a drive mechanism; the traveling wheels are matched and assembled with the guide rail, and the lifting device is a turbine lifter or a hydraulic lifter mechanism. The lifting rod of the turbine lifter or the piston rod of the hydraulic cylinder is fixedly connected to the steel ingot receiving part as the output end. Vertical precision guidance is achieved through the lifting rod or guide rod to ensure that the lifting action is stable and without shaking. Furthermore, the steel ingot receiving component includes a connecting arm and a shovel head; the connecting arm is fixedly connected to the output end of the lifting device, the shovel head is made of high-temperature resistant and wear-resistant steel and the surface is polished; a heat-insulating buffer layer of high-temperature resistant ceramic fiber material is provided between the shovel head and the connecting arm, the edge of the shovel head is provided with a guide chamfer, and a counterweight is provided at the opposite end of the shovel head; Furthermore, the steel ingot non-impact conveying device also includes a heat insulation protection device. The heat insulation protection device adopts a water-cooled heat insulation cover or a high-temperature resistant heat insulation board. The heat insulation protection device is fixedly arranged on the side of the guide rail, the moving trolley and the lifting device facing the heating furnace to block the high temperature radiation of the furnace body and protect the equipment components. Furthermore, the steel ingot non-impact conveying device also includes a control system, which is electrically connected to the drive mechanism of the moving trolley and the lifting device, and the control system is linked with the heating furnace control system and the roller conveyor control system to realize the fully automated interlocked control of the entire process of receiving, moving, releasing, retreating and conveying ingots. Furthermore, the counterweight is used to balance the weight of the steel ingot receiving component and the shovel head, as well as the unloaded lifting load, reduce the driving pressure of the lifting device, and make the steel ingot descend at a uniform speed and slowly, thus completely eliminating the impact load of the steel ingot on the roller conveyor. Furthermore, the drive mechanism is connected to the walking wheel drive and is used to drive the mobile trolley to move reciprocally in a straight line along the guide rail; the drive mechanism is equipped with a position encoder and a travel limit switch to achieve precise positioning and overtravel protection. A method for conveying steel ingots without impact based on any of the above-mentioned steel ingot non-impact conveying devices includes the following steps: S1. The control system links and controls the moving trolley to move precisely along the guide rail to the ingot receiving position at the furnace opening of the heating furnace. The lifting device drives the steel ingot receiving part to descend and adjust it to the preset ingot receiving height. S2. After the heating furnace finishes tapping the steel, the paired shovel-type steel ingot receiving parts smoothly lift the steel ingot, completing the impact-free ingot receiving. S3. The moving trolley moves smoothly along the guide rail, conveying the steel ingot to the position directly above the conveyor roller table; S4. The lifting device drives the steel ingot receiving component to descend at low speed. The steel ingot receiving component descends to the corresponding roller gap and slowly places the steel ingot on the roller of the conveyor. After the steel ingot is fully supported by the roller, the steel ingot receiving component drives the shovel head to continue to descend slightly. The shovel head is located within the roller gap and roller height range. S5. The moving trolley drives the steel ingot receiving component, the shovel head, and the counterweight to move backward. The shovel head completely leaves the bottom area of ​​the steel ingot. After moving backward, the lifting device drives the steel ingot receiving component to rise and reset to the safe position. S6. The control system is activated in conjunction with the roller conveyor control system, causing the conveyor rollers in front of the furnace to rotate and drive the steel ingots to complete the subsequent conveying operation.

[0007] The present invention has the following positive effects: 1. The present invention sets up a counterweight structure to balance the self-weight and load of the lifting mechanism. After the steel ingot is completely placed on the roller conveyor, the steel ingot is lowered slowly and uniformly. The shovel head moves down slightly and embeds itself into the gap between the rollers, which completely eliminates the impact load of traditional rigid material dropping, effectively protects the core components such as roller conveyor rollers and bearings, greatly reduces equipment wear and failure rate, extends equipment service life, and reduces production and maintenance costs. 2. The invention features a unique roller gap avoidance and retraction process. After the steel ingot is placed and supported, the steel ingot receiving component moves slightly within the roller gap and roller surface height range of the front roller table, and then completes the horizontal retraction action. This completely solves the problem of interference and scratches between the receiving structure and the roller table and steel ingot, avoids scratches on the surface of the steel ingot and equipment jamming failures, and ensures production continuity. 3. The guide rail of this invention adopts a quenched heavy-duty structure, combined with a gear rack or chain heavy-duty transmission structure, which is suitable for high-temperature heavy-duty steel ingot conveying conditions. It has strong structural stability and high positioning accuracy. The drive mechanism is equipped with an encoder and limit switch to achieve precise positioning and overtravel protection, which greatly improves the safety and stability of operation. 4. This invention is equipped with a dedicated heat insulation and protection device, which can effectively block the high-temperature heat radiation of the heating furnace and avoid problems such as deformation, aging, and malfunction of guide rails, trolleys, lifting mechanisms, and electrical components due to high temperatures. It is suitable for the harsh high-temperature working environment in front of the furnace and the equipment has higher operational reliability. 5. This invention adopts an integrated shovel-type receiving structure, equipped with a heat insulation buffer layer and guide chamfer, which not only ensures the stable receiving of steel ingots without deviation or shaking, but also blocks the transmission of high temperature and buffers the stress, while facilitating the alignment and receiving of ingots; the paired shovel-type structure distributes the stress evenly and is suitable for the transportation needs of heavy steel ingots. 6. This invention achieves full-process electrical interlocking and linkage of heating furnace, conveying device and roller system, with a high degree of automation, no need for manual intervention, orderly closed-loop operation process, greatly improves the efficiency of steel ingot conveying operation, and is suitable for the needs of large-scale continuous metallurgical production.

Detailed Implementation

[0014] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] This embodiment provides a non-impact conveying device for steel ingots, referring to... Figures 1-4 The non-impact conveying device for steel ingots includes paired guide rails 1, moving trolleys 2, lifting devices 3, steel ingot receiving components 4, counterweights 7, supporting columns 5, and a conveying roller conveyor composed of several rollers 11. One end of the guide rail 1 is fixed to the embedded part of the steel structure in front of the heating furnace, and the other end is supported by the supporting column 5. The bottom of the supporting column 5 is fixed to the ground with anchor bolts, and the overall installation is stable and can withstand heavy conveying loads.

[0016] The mobile trolley 2 is slidably mounted on the paired guide rails 1. The mobile trolley 2 consists of the trolley body, traveling wheels and drive mechanism 6. The traveling wheels 14 are precisely matched with the guide rails 1. The drive mechanism 6 adopts a gear and rack transmission structure on the guide rail, which has a large load-bearing capacity and smooth transmission. It is also equipped with a position encoder and a travel limit switch, which can accurately control the traveling position of the mobile trolley 2, realize the precise alignment of the furnace mouth ingot receiving station and the roller conveyor ingot placement station, and also have an overtravel power-off protection function to avoid equipment collision damage.

[0017] The lifting device 3 is fixedly installed on the mobile trolley 2 and uses a turbine lift. The output end of the lifting rod 8 of the turbine lift is connected to the steel ingot receiving component 4. The meshing of the turbine and gear in the turbine lift prevents lifting offset, ensuring that the vertical lifting of the steel ingot receiving component 4 is stable and without swaying or offset, with high lifting accuracy and smooth operation. The counterweight 7 is set at the end opposite the rear winding head of the steel ingot receiving component 4 to balance the self-weight of the receiving structure and the unloaded load, as well as the working pressure of the turbine lift, ensuring uniform and stable descent and placement.

[0018] The steel ingot receiving component 4 is a paired shovel structure, consisting of a connecting arm and a shovel head 9. The shovel head 9 is made of high-strength, high-temperature resistant, and wear-resistant steel with a polished surface to reduce friction damage to the steel ingot. A high-temperature resistant ceramic fiber heat insulation buffer layer is set between the shovel head 9 and the connecting arm to block the high-temperature conduction of the furnace body and buffer the impact force of receiving the ingot. The edge of the shovel head 9 is provided with a guide chamfer to facilitate the connection with the furnace opening for steel tapping and improve the smoothness of ingot alignment.

[0019] A high-temperature resistant heat insulation board is installed on the side of the device facing the heating furnace as a heat insulation and protection device, effectively blocking the high-temperature heat radiation of the furnace body and protecting the guide rail 1, moving trolley 2, lifting device 3 and electrical components, preventing high-temperature aging, deformation and failure. The device is equipped with an independent control system, which is linked with the drive mechanism 6, lifting device 3, heating furnace system and roller conveyor system to realize fully automated interlocked operation.

[0020] This embodiment also provides a method for non-impact conveying of steel ingots, the specific operation process of which is as follows: In the initial stage of operation, the equipment is in the standby reset position. After receiving the steel tapping signal from the heating furnace, the control system starts the conveying process. First, the control system controls the moving trolley 2 to move precisely along the guide rail 1 to the position of the furnace opening 12. The lifting device 3 drives the ingot receiving part 4 to descend to the preset ingot receiving height, waiting for steel to be tapped.

[0021] After the furnace body 13 has finished heating, the high-temperature steel ingot 10 is pushed out through the furnace opening 12. Pairs of shovels 9 smoothly support the bottom of the steel ingot 10, completing the impact-free ingot receiving operation. After receiving, the ingot is horizontally reversed or the lifting device 3 slightly raises the steel ingot receiving component 4, causing the steel ingot 10 to detach from the furnace opening contact surface and rise to a safe height, avoiding scraping or collision during the translation process. After a slight lift, the drive mechanism 6 drives the moving trolley 2 to move smoothly along the guide rail 1, conveying the steel ingot 10 to the designated work position directly above the conveyor roller table.

[0022] Once in position, the lifting device 3 drives the ingot receiving component 4 downwards at a low, constant speed. The ingot receiving component 4 descends into the corresponding gap between the rollers 11, slowly placing the ingot 10 onto the top surface of the rollers 11. After the bottom of the ingot 10 is fully in contact with the rollers 11 and all its weight has been transferred to the roller conveyor, the lifting device 3 continues to descend a small, preset distance, positioning the shovel head 9 entirely within the height range of the rollers 11, completing the avoidance preparation.

[0023] Then, the moving trolley 2 moves the ingot receiving component 4 and the shovel head 9 horizontally backward, so that the shovel head 9 is completely separated from the bottom of the ingot 10 and the roller conveyor area, without any mechanical interference or scraping or jamming throughout the process. After retracting to the correct position, the lifting device 3 drives the ingot receiving component 4 to rise as a whole and reset to the safe standby height.

[0024] Finally, the control system is linked with the roller conveyor control system to start the conveyor rollers. The rollers 11 rotate and drive the steel ingots 10 forward to complete a single steel ingot non-impact conveying operation. Then the equipment stands by and waits for the next steel output command, and the cycle continues.

[0025] In this embodiment, two movable trolleys 2 are provided. The moving mechanism 6 of each movable trolley 2 includes four geared motors on both sides, driving rollers or gears to move on guide rails on both sides. The four geared motors on the movable trolley 2 move synchronously under the control of the controller. Similarly, four identical lifting devices 3 are provided on one movable trolley 2. Each lifting device 3 includes a geared motor. During operation, the geared motors on the four lifting devices run synchronously under the control of the controller. The aforementioned geared motors are equipped with encoders for feeding back position information to the controller.

[0026] The present invention has the following positive effects: 1. This invention adds a counterweight 7 structure to balance the self-weight of the lifting mechanism and the load-bearing capacity. The lifting device 3 drives the lifting rod 8 and the steel ingot receiving part 4 to work. After the steel ingot 10 has completely fallen into the roller 11 roller track, it can achieve uniform and slow descent. The shovel head 9 sinks slightly and embeds into the roller gap, completely abandoning the traditional rigid material dropping method, eliminating impact load, effectively protecting key components such as roller 11 and bearings, reducing equipment wear and failure frequency, extending equipment service life, and reducing production and maintenance costs. 2. The invention pioneers a roller gap avoidance and retraction process: After the steel ingot 10 is placed in position to bear the load, the steel ingot receiving part 4 first makes a small avoidance within the roller gap and roller surface height range of the roller 11, and then performs a horizontal retraction action to completely avoid interference and scratches between the steel ingot receiving part 4 and the roller table and the steel ingot 10, prevent damage to the surface of the steel ingot 10 and equipment jamming, and ensure the continuous and stable operation of the production line. 3. The equipment guide rail 1 adopts a quenched heavy-duty structure, equipped with a gear and rack or chain heavy-duty transmission mechanism, and driven by the drive mechanism 6, which can meet the high temperature and heavy load conveying conditions of steel ingot 10. The moving trolley 2 slides smoothly along the guide rail 1, with a stable overall structure and precise positioning; the drive mechanism 6 integrates an encoder and limit switch to achieve precise motion control and overtravel safety protection, significantly improving the safety and stability of equipment operation; 4. The equipment is equipped with a dedicated heat insulation protection device, which can effectively block the high-temperature heat radiation emitted by the furnace body 13 and furnace opening 12, and prevent the guide rail 1, moving trolley 2, lifting device 3 and various electrical components from deforming, aging and failing due to high temperature. It is suitable for the harsh high-temperature working conditions in front of the furnace and further improves the reliability of equipment operation. 5. The steel ingot receiving component 4 of this invention adopts an integrated shovel structure with a shovel head 9 at the end, equipped with a heat insulation buffer layer and guide chamfer. It can not only stably support the steel ingot 10 and prevent displacement and shaking, but also block the transmission of high temperature and buffer the impact load, while facilitating precise alignment and receiving of the ingot. The paired shovel structures are evenly stressed and, together with the supporting column 5, provide overall support, which can meet the requirements for the transfer of large-tonnage steel ingots 10. 6. This device is installed stably by relying on the support column 5. The walking wheels 14 and guide rails enable the whole machine to move flexibly. It realizes the electrical interlocking and linkage of the furnace body 13 heating furnace, conveying equipment and roller 11 roller system throughout the process. It has a high level of automation, no manual intervention is required throughout the process, the operation process is closed and orderly, and the conveying efficiency of steel ingot 10 is greatly improved. It is suitable for large-scale and continuous production scenarios in the metallurgical industry.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
