Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for steel component processing, and in particular, it is a feeding device for steel components. Background Technology

[0002] In the steel structure processing, the loading of steel components (such as H-beams, angle steel, steel plates, etc.) usually relies on manual labor in conjunction with cranes or forklifts. Operators need to pay close attention to the position of the steel structure at all times. Once a deviation is detected, the machine needs to be stopped for adjustment, which not only interrupts the conveying process but also consumes a lot of time and manpower. When the device is not capable of guiding steel structures of different widths, the steel structure is prone to deviation and skew during the conveying process, affecting the stability of the conveying.

[0003] A search revealed Chinese patent document (authorization announcement number CN218225119U), which discloses a feeding device for steel components, relating to the field of steel component production technology. This utility model, through the arrangement of multiple parallel feeding units and a positioning mechanism, transports the steel components along the feeding mechanism to a lifting mechanism, which then raises the components. Subsequently, the positioning mechanism pushes the steel components to slide along the lifting mechanism and align them to a designated position. Finally, the lifting mechanism places the steel components onto a feeding mechanism, which then transports the components to a designated position on a laser cutting machine, ensuring cutting accuracy. This device can meet basic usage requirements; however, when its guiding capability for steel structures of different widths is insufficient, the steel structures are prone to shifting or tilting during transport, affecting transport stability. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for steel components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for steel components, comprising a base for supporting the steel structure, a fixing frame for providing installation space installed on the top of the base, and fixing plates installed on both sides of the fixing frame;

[0006] Both of the fixed plates have multi-circle guide grooves inside to limit the direction of movement. Multiple springs for adjustment are connected inside the multi-circle guide grooves. One end of each spring is connected to a multi-circle moving plate. The end of the multi-circle moving plate is slidably disposed inside the multi-circle guide groove. A vertical support plate is installed at the end of the multi-circle moving plate away from the spring. A horizontal support plate is installed on the side of the vertical support plate. Multiple vertical rotating columns for contacting the steel structure are rotatably disposed at the bottom of the horizontal support plate. One end of each vertical rotating column is connected to a limiting plate to prevent the vertical rotating column from falling.

[0007] Preferably, the limiting disc is rotatably positioned above the horizontal support plate, and the end of the vertical rotating column completely penetrates the interior of the horizontal support plate.

[0008] Preferably, the side of the vertical support plate away from the horizontal support plate is connected to a plurality of guide posts for limiting the displacement of the vertical support plate, and the guide posts completely penetrate the side of the fixed plate.

[0009] Preferably, a locking plate is connected to the side of the vertical support plate near the guide post, and the locking plate completely penetrates the side of the fixing plate.

[0010] Preferably, the surface of the locking plate is provided with a locking groove for fixing the locking plate, and the top of the fixing plate is rotatably provided with a locking thread post for cooperating with the locking groove.

[0011] Preferably, a power unit for providing driving force is installed on the top of the base, a drive unit is installed at the output end of the power unit, and a conveyor belt for feeding steel components is installed on the movable part of the drive unit.

[0012] Preferably, the top of the fixing frame is equipped with a guide plate to assist the steel structure in entering, and the interior of the fixing frame is rotatably equipped with multiple transverse rotating columns for contacting the bottom of the steel structure.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This steel component feeding device, thanks to its rotating column structure, allows steel components of varying widths to enter the device. The sides of the steel components press against the vertical rotating column, causing the vertical support plate and multi-circular moving plate to slide along the multi-circular guide groove. At this time, the springs extend and retract according to the component width, ensuring the vertical rotating column remains tightly fitted to the component's side through elastic force. Real-time spring force adjustment ensures continuous and effective lateral limiting, preventing component deviation or skewing during transport. Simultaneously, the rotational characteristics of the vertical rotating column convert sliding friction into rolling friction, reducing wear on the component surface. This structure enables adaptive guidance for steel components of different specifications, significantly improving the device's versatility and transport stability.

[0015] This steel component loading device, thanks to the structure of the locking plate, allows operators to quickly release or fix the position of the vertical support plate when adjusting steel components of significantly different widths. This is achieved by simply rotating the locking threaded column to disengage from or engage with the locking groove of the locking plate. Combined with the guide column's restriction on the vertical support plate's displacement direction, the adjustment process eliminates the need for repeated verticality calibration, allowing a single person to complete the width adjustment. Compared to traditional bolt fixing methods, this significantly improves adjustment efficiency. Furthermore, the spaced locking groove design enables precise, graded positioning of the width, ensuring the symmetry of the vertical support plates on both sides and providing a stable reference for subsequent adaptive guidance, balancing ease of operation and adjustment accuracy.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The device shown is a feeding device for steel components, including a base 1 for supporting the steel structure, a fixing frame 2 for providing installation space installed on the top of the base 1, and fixing plates 202 installed on both sides of the fixing frame 2.

[0027] Both fixed plates 202 have multi-circle guide grooves 203 inside to limit the direction of movement. Multiple springs 204 for adjustment are connected inside the multi-circle guide grooves 203. One end of each spring 204 is connected to a multi-circle moving plate 205. The end of the multi-circle moving plate 205 is slidably disposed inside the multi-circle guide grooves 203. A vertical support plate 3 is installed at the end of the multi-circle moving plate 205 away from the springs 204. A horizontal support plate 301 is installed on the side of the vertical support plate 3. Multiple vertical rotating columns 303 for contacting the steel structure are rotatably disposed at the bottom of the horizontal support plate 301. One end of each vertical rotating column 303 is connected to a limiting plate 302 to prevent it from falling. The operator can adjust the position of the vertical support plate 3 to match the size of the component according to the width of the steel component: loosen the locking threaded column 306 at the top of the fixed plate 202 so that it is disengaged from the locking groove 305 on the surface of the locking plate 304, thereby releasing the fixation of the vertical support plate 3. At this time, the vertical support plate 3 can move along the direction of the guide column 206 (the guide column 206 passes through the fixed plate 202, restricting the movement direction of the vertical support plate 3), the multi-circle moving plate 205 slides in the multi-circle guide groove 203, and the spring 204 expands and contracts according to the displacement of the vertical support plate 3, forming an elastic buffer, activating the power unit 101 at the top of the base 1. The power unit 101 drives the conveyor belt 103 to operate through the drive unit 102. The conveyor belt 103 applies frictional force to the steel component, driving the component to move along the conveying direction. During this process, the two sides of the component contact the vertical rotating column 303 at the bottom of the horizontal support plate 301 on the side of the vertical support plate 3: the vertical rotating column 303 reduces the friction on the side of the component by rotating, and at the same time, under the elastic force of the spring 204, the multi-circle moving plate 205 pushes the vertical support plate 3, so that the vertical rotating column 303 always fits against the side of the component, realizing adaptive limiting of components of different widths and preventing deviation during the conveying process. The limiting plate 302 (located above the horizontal support plate 301) prevents the vertical rotating column 303 from falling off the horizontal support plate 301, thus ensuring structural stability.

[0028] The limiting plate 302 is rotatably mounted above the horizontal support plate 301. The end of the vertical rotating column 303 completely penetrates the interior of the horizontal support plate 301. Multiple guide columns 206 for limiting the displacement of the vertical support plate 3 are connected to the side of the vertical support plate 3 away from the horizontal support plate 301. The guide columns 206 completely penetrate the side of the fixed plate 202. For steel components with slight width variations, the spring 204 drives the multi-circle moving plate 205 to slide slightly in the multi-circle guide groove 203 by adjusting the extension amount in real time. This ensures that the vertical support plate 3 and the vertical rotating column 303 always maintain contact with the side of the component, ensuring the stability of the component's posture throughout the entire conveying process, and finally completing the loading operation of the steel component.

[0029] A locking plate 304 is connected to the side of the vertical support plate 3 near the guide post 206. The locking plate 304 completely penetrates the side of the fixing plate 202. The surface of the locking plate 304 is provided with a locking groove 305 for fixing the locking plate 304. The top of the fixing plate 202 is rotatably provided with a locking thread post 306 for cooperating with the locking groove 305. After adjusting to a suitable width, the locking thread post 306 is rotated in the opposite direction to make it snap into the corresponding locking groove 305, thus completing the fixing of the vertical support plate 3.

[0030] A power unit 101 for providing driving force is installed on the top of the base 1. The power unit 101 is composed of an AC asynchronous motor or a servo motor, with a built-in reducer and braking unit. The motor output shaft is connected to the drive unit 102 through a coupling. The bottom is fixed to the mounting base on the top of the base 1 by bolts. After receiving external control signals (such as start / stop commands, speed adjustment signals), the motor rotor rotates to generate torque. The speed is reduced and the output torque is increased by the reducer. The power is transmitted to the drive unit 102 through the coupling. The braking unit can quickly lock the output shaft when the machine stops to prevent the conveyor belt 103 from continuing to run due to inertia. As the power source of the entire conveying system, it provides stable torque and adjustable speed for the operation of the conveyor belt 103. The conveying speed of the conveyor belt 103 can be adjusted by controlling the motor speed to adapt to the conveying needs of steel components of different weights and sizes. The output end of the power unit 101 is equipped with the drive unit 102, which includes a drive roller, a bearing housing, and a transmission gear set (or chain drive mechanism). The drive roller is mounted in bearing housings at both ends via bearings, which are fixed to the base 1. One end of the roller is connected to the output end of the power unit 101 via gears or chains, and the other end is equipped with a fine-tuning mechanism for tension adjustment. The torque output by the power unit 101 is transmitted to the drive roller through gear meshing or chain drive, causing the roller to rotate around its own axis. The fine-tuning mechanism can change the distance between the drive roller and the driven roller (the support roller below the conveyor belt 103) by adjusting the position of the bearing housing, thereby adjusting the tension of the conveyor belt 103. This converts the rotational motion of the power unit 101 into the linear motion of the conveyor belt 103. The conveyor belt is driven by the friction between the drive roller and the conveyor belt 103, while the tension adjustment ensures that the conveyor belt does not slip, guaranteeing power transmission efficiency. The movable part of the drive unit 102 is equipped with a conveyor belt 103 for feeding steel components. The conveyor belt 103 is made of high-strength rubber or metal mesh, with multiple layers of canvas or steel wire cord embedded inside to enhance tensile strength. The surface is covered with a wear-resistant rubber layer (or metal protrusions); the conveyor belt wraps around the drive roller, driven roller and idler group to form a closed loop structure. Driven by the friction of the drive roller, the conveyor belt 103 moves in a loop along the loop track. After the steel component is placed on the surface of the conveyor belt, it moves synchronously with the conveyor belt by relying on the friction between the belt and the component. The idler group provides support under the conveyor belt to prevent the belt from sagging due to the weight of the component. It directly carries and transports the steel component. The linear transport of the steel component is achieved through continuous movement. The wear-resistant structure on the surface reduces friction loss with the component. At the same time, it is suitable for steel components of different shapes (such as flat plates and profiles) to ensure that the transport process is smooth and without deviation. The top of the fixed frame 2 is equipped with a guide plate 104 for assisting the steel structure to enter. The inside of the fixed frame 2 is rotatably equipped with multiple transverse rotating columns 201 for contacting the bottom of the steel structure. The steel component enters the device from the guide plate 104 at the top of the fixed frame 2. The guide plate 104 guides the component to move towards the conveyor belt 103 by tilting.The bottom of the component contacts the transverse rotating column 201 inside the fixed frame 2. The transverse rotating column 201 reduces the frictional resistance between the component and the fixed frame 2 by rotating, and helps the component to smoothly transition to the conveyor belt 103.

[0031] To avoid environmental and maintenance factors affecting the operation of the device, adjustments can be made according to actual usage. For example, retractable dust baffles (made of wear-resistant rubber) can be installed on both sides of the conveyor belt 103, with the bottom of the baffles fitting snugly against the surface of the conveyor belt 103 to prevent dust carried by the steel components from spreading to the power unit 101 and drive unit 102 during conveying. Brush sealing strips can be installed at the opening of the multi-circle guide groove 203 to prevent dust from entering the groove and affecting the sliding of the multi-circle moving plate 205. The multi-circle guide groove 203 consists of 3-5 concentric circular arc grooves. The components are assembled, with a polytetrafluoroethylene coating applied inside the groove to ensure that the sliding resistance of the multi-circular moving plate 205 is ≤5N; a 100mm high waterproof platform is added to the bottom of the base 1, and IP65-rated waterproof covers are installed on the housings of the power unit 101 and the drive unit 102, with nitrile rubber used at the contact points between the covers and the base 1; drainage holes are opened at the bearing seats of the transverse rotating column 201, and lithium-based grease (water-resistant) is injected to prevent water accumulation from causing bearing corrosion; if the device is used in high-temperature environments such as welding workshops, aluminum heat sinks and shafts are added to the outside of the power unit 101 (motor). The fan (temperature-controlled automatic start) ensures the motor operating temperature does not exceed 65℃; the conveyor belt 103 is made of high-temperature resistant aramid canvas with a silicone coating, capable of withstanding ambient temperatures below 150℃; the following components are required to be maintained every 500 hours of operation: ① Horizontal rotating column 201 and vertical rotating column 303: after disassembly, clean the old grease from the bearings and refill with extreme pressure lithium-based grease; ② Multi-circle guide groove 203: blow away internal dust with a high-pressure air gun and apply graphite grease; ③ Locking threaded column 306: apply anti-jamming agent to ensure tight locking. The release operation is smooth; the connection between the vertical rotating column 303 and the limit plate 302 is changed to a quick-release bolt fixation, which allows for the replacement of worn rotating columns without special tools; the two ends of the spring 204 are connected by a snap-fit, which facilitates the batch replacement of fatigued springs; a temperature and humidity sensor and a dust concentration sensor are installed on the top of the fixed frame 2 to monitor environmental parameters in real time; when the detected value exceeds the equipment's tolerance range (such as humidity > 85%, dust concentration > 10mg / m³), the control system will issue an audible and visual alarm to remind the operator to take protective measures.

[0032] Working principle

[0033] This feeding device for steel components operates as follows: First, the operator adjusts the position of the vertical support plate 3 according to the width of the steel component. Then, the locking threaded post 306 on the fixing plate 202 is loosened, disengaging it from the locking groove 305 of the locking plate 304. The vertical support plate 3 moves along the guide post 206, and the multi-circle moving plate 205 slides within the multi-circle guide groove 203. The spring 204 extends and retracts accordingly to provide cushioning. After adjustment, the locking threaded post 306 is rotated in the opposite direction to secure it. The steel component enters through the guide plate 104 at the top of the fixing frame 2 and is guided by the guide plate 104 to move towards the conveyor belt 103. The bottom contacts the transverse rotating post 201 within the fixing frame 2, reducing friction and facilitating the transition. The power unit 101 of the base 1 is activated, driving the conveyor belt 103 via the drive unit 102. The conveyor belt 103 then drives the component to move. During the process, the two sides of the component contact the vertical rotating column 303 at the bottom of the horizontal support plate 301 on the vertical support plate 3. The vertical rotating column 303 rotates to reduce friction, and the spring 204 pushes the vertical support plate 3 to make the vertical rotating column 303 fit against the side of the component. The limiting plate 302 prevents it from falling off. When encountering components with slight changes in width, the spring 204 adjusts the extension and contraction in real time, driving the multi-circle moving plate 205 to slide, ensuring that the vertical support plate 3 and the vertical rotating column 303 are always in contact with the component, ensuring stable conveying and completing the loading.
