Description

Technical Field

[0001] This utility model relates to the field of steel plate processing equipment technology, and in particular to a large-size steel plate collection structure. Background Technology

[0002] In modern industrial manufacturing, large-size steel plates are widely used as basic raw materials in key industries such as shipbuilding, pressure vessel production, and large-scale engineering machinery assembly. As industrial products develop towards larger sizes and higher precision, the demand for large-size steel plates continues to grow. The size of a single piece often reaches several meters or even more than ten meters, and the weight ranges from hundreds of kilograms to several tons. This places extremely high technical requirements on the collection and transportation of steel plates after production.

[0003] Currently, after large-size steel plates are processed through rolling, cutting, and other processes, they usually need to be transported to a collection area for stacking and storage via conveying equipment. Traditional collection methods mostly rely on a support-type collection structure, which guides the steel plates to fall through guide components fixed on both sides of the support. However, due to the large weight and uneven rigidity distribution of large-size steel plates, during the vertical fall, the front end of the steel plate is prone to tilting downwards due to the influence of gravity, air resistance, and the conveying speed at the end of the conveying equipment. When the tilted steel plate comes into contact with the already stacked steel plates below, the sharp edge or protruding part of the front end will directly scrape the surface of the steel plate below, causing scratches, dents, and other damage to the processed steel plate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing large-size steel plates. Due to their large weight and uneven rigidity distribution, large-size steel plates are prone to tilting downwards during vertical descent due to gravity, air resistance, and the conveying speed at the end of the conveying equipment. When the tilted steel plate comes into contact with the stacked steel plates below, the sharp edges or protruding parts of the front end will directly scrape the surface of the steel plate below, causing scratches, dents, and other damage to the already processed steel plate. Therefore, this invention proposes a large-size steel plate collection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-size steel plate collection structure includes an installation platform. Guide wheels are fixedly installed at the left and right ends of the top of the installation platform. An installation frame is fixedly connected to the outer wall of the installation platform. A hydraulic cylinder is fixedly installed on the top of the installation frame. The hydraulic cylinder is connected to a fixed plate through an inclined transmission structure. A roller is rotatably connected to the opposite side of the fixed plate. A U-shaped frame is fixedly connected to the outer wall of the inlet side of the installation platform. A blowing and floating component is provided inside the U-shaped frame to keep the front end of the steel plate horizontal.

[0007] Preferably, the tilting transmission structure includes a connecting plate fixedly connected to the telescopic end of the hydraulic cylinder, lifting frames fixedly connected to the bottom of both ends of the connecting plate, a rotating block rotatably connected to the inner wall of the mounting frame, one end of the rotating block being fixedly connected to the outer wall of the fixed plate, and the other end of the rotating block being rotatably connected to the inner wall of the lifting frame.

[0008] Preferably, a fixing block is fixedly connected to the inner wall of the mounting frame, and a stop bar is fixedly connected to the inner wall of the lifting frame. The stop bar is positioned above the fixing block, and when the bottom of the stop bar abuts against the top of the fixing block, the fixing plate is in a parallel state.

[0009] Preferably, the top of the connecting plate is fixedly connected to a limiting post, and two limiting posts are provided and symmetrically distributed on both sides of the hydraulic cylinder. The limiting posts pass through the mounting frame and are slidably connected.

[0010] Preferably, the blowing assembly includes a cylinder fixedly installed on the outer wall of a U-shaped frame. The inner wall of the U-shaped frame has grooves on both sides, and a rectangular frame is slidably connected in the grooves. A collar is fixedly connected to the inner wall of the rectangular frame, and an air diffuser is fitted inside the collar. An air duct is provided below the air diffuser, and a blower is connected to the outside of the air duct.

[0011] Preferably, the telescopic end of the cylinder is fixedly connected to the outer wall of the rectangular frame, one end of the air duct is fixedly connected to the air expansion duct, and the other end of the air duct is fixedly connected to the blower.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When in use, this utility model can be flexibly adjusted by using an inclined transmission structure in conjunction with a hydraulic cylinder: the extension end of the hydraulic cylinder drives the connecting plate and the lifting frames at both ends to move, thereby pushing the rotating block to rotate around the inner wall of the mounting frame, and finally controlling the tilt angle of the fixed plate, so that the large steel plate placed flat on the roller can fall directly below, avoiding the front end of the steel plate from scraping the surface of the steel plate below.

[0014] 2. In use, this utility model can be installed with a blowing and floating component on the inlet side of the mounting frame. The airflow generated by the blower is evenly applied to the front end of the falling steel plate through the air duct and the air diffuser. This can counteract the tilting tendency of the steel plate caused by uneven weight, gravity and air resistance, so that the front end of the steel plate always remains horizontal. This completely solves the problem of scratches, dents and other damage caused by the sharp edges or protrusions of the tilted steel plate scraping the stacked steel plates below during the traditional collection process, and significantly improves the yield and surface quality of the steel plate.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 A large-size steel plate collection structure includes a mounting platform 1, a guide and positioning assembly, an tilting transmission assembly, a receiving assembly, and a blowing and floating assembly 8. The connection relationships and functions of each component are as follows:

[0021] Mounting platform 1 serves as the supporting foundation for the overall structure, constructed from welded steel profiles. Its bottom is secured to the ground with expansion bolts to ensure the stability of the device during operation. Guide wheels 2 are symmetrically mounted on the left and right ends of the top of mounting platform 1. Each guide wheel 2 features a rubber outer layer covering a metal hub, and its axle is rotatably connected to mounting platform 1 via bearings. When the steel plate enters the collection structure from the conveyor line, the guide wheels 2 guide and limit the movement of the steel plate's edges, preventing it from shifting during transport. The rubber outer layer also reduces scratch damage to the steel plate's edges.

[0022] A mounting frame 3 is fixedly connected to the middle of the outer wall of the mounting platform 1 by bolts. The mounting frame 3 has a "door frame" structure, and its top crossbeam is set horizontally for mounting the drive components.

[0023] Specifically:

[0024] A hydraulic cylinder 4 is fixedly installed at the top center of the mounting bracket 3. The cylinder body of the hydraulic cylinder 4 is bolted to the mounting bracket 3 via a flange. The telescopic end of the hydraulic cylinder 4 is vertically downward, and a connecting plate 9 is fixedly connected to the end of the telescopic end by welding. The connecting plate 9 is a rectangular steel plate structure, and its length is adapted to the inner width of the mounting bracket 3 to transmit the driving force of the hydraulic cylinder 4.

[0025] The tilting transmission structure consists of a connecting plate 9, a lifting frame 10, and a rotating block 11. The lifting frame 10 is symmetrically welded to the bottom of both ends of the connecting plate 9. The lifting frame 10 has a "U"-shaped groove structure, with its opening facing the inside of the mounting frame 3. Rotating blocks 11 are rotatably connected to the inner walls of the vertical beams on both sides of the mounting frame 3 via pins. The rotating block 11 has an "L"-shaped structure; one end (the end furthest from the mounting frame 3) is welded and fixed to the outer wall of the fixing plate 5, and the other end (the end closest to the mounting frame 3) is rotatably connected to the inner wall of the lifting frame 10 via a pin.

[0026] The fixed plate 5 is a rectangular steel plate, the length of which is greater than the width of the large-size steel plate. On opposite sides of the fixed plate 5 (along the steel plate conveying direction), rollers 6 are rotatably connected via bearings. The rollers 6 are evenly distributed along the length of the fixed plate 5 (with a spacing of 200-300mm). When the steel plate falls onto the fixed plate 5, the rollers 6 can convert the sliding friction between the steel plate and the fixed plate 5 into rolling friction, reducing the resistance to the movement of the steel plate and facilitating subsequent stacking and sorting.

[0027] To ensure the angular accuracy of the fixing plate 5 during adjustment and avoid excessive tilting, fixing blocks 12 are welded to the inner wall (both vertical beams) of the mounting frame 3, and baffles (long strip steel plates with a length adapted to the height of the lifting frame 10) are welded to the inner wall of the lifting frame 10. When the telescopic end of the hydraulic cylinder 4 is fully extended, the lifting frame 10 drives the rotating block 11 to rotate around the pin until the bottom of the baffle abuts against the top of the fixing block 12. At this time, the fixing plate 5 is in a horizontal state and can serve as the initial receiving position for the steel plate. When the telescopic end of the hydraulic cylinder 4 retracts, the lifting frame 10 pulls the rotating block 11 upward, causing the fixing plate 5 to tilt around the connecting pin between the rotating block 11 and the mounting frame 3, thereby adjusting the receiving angle of the steel plate (tilt angle range is 0°-30°) to accommodate the collection needs of steel plates of different thicknesses.

[0028] In addition, two limiting posts 13 are symmetrically fixedly connected to the top of the connecting plate 9. The limiting posts 13 are respectively set on both sides of the hydraulic cylinder 4, and the limiting posts 13 vertically upward penetrate through the top crossbeam of the mounting frame 3 and are slidably connected to the crossbeam. The setting of the limiting posts 13 can prevent the connecting plate 9 from horizontally shifting during the extension and retraction of the hydraulic cylinder 4, ensuring the stability of the driving force transmission, and at the same time avoiding the piston rod of the hydraulic cylinder 4 from bending and being damaged due to unilateral force.

[0029] To address the issue of sagging and deformation at the front end of the steel plate as it enters the collection structure, a U-shaped frame 7 is welded to the outer wall of the inlet side of the mounting platform 1 (i.e., the starting end where the steel plate enters). The opening of the U-shaped frame 7 faces the steel plate conveying direction. A blowing and floating assembly 8 is installed inside the U-shaped frame 7 to blow air and lift the front end of the steel plate, keeping it horizontal. Specifically:

[0030] The air-blowing assembly 8 includes a cylinder 14, a rectangular frame 16, a collar 17, an air diffuser 18, an air duct 19, and a blower 20. The cylinder 14 is bolted to the outer wall of the U-shaped frame 7 (the side furthest from the mounting platform 1), with the telescopic end of the cylinder 14 pointing horizontally towards the inside of the U-shaped frame 7. On both sides of the inner wall of the U-shaped frame 7, vertical grooves 15 are formed, within which the rectangular frame 16 is slidably connected. The two edges of the rectangular frame 16 are embedded in the grooves 15, and the outer wall of the rectangular frame 16 is welded and fixed to the telescopic end of the cylinder 14. The telescopic movement of the cylinder 14 causes the rectangular frame 16 to move up and down along the grooves 15, thereby adjusting the air-blowing height.

[0031] The inner wall of the rectangular frame 16 is welded with a collar 17, which is a circular metal ring. An air diffuser 18 is fitted inside the collar 17. The air diffuser 18 is made of wear-resistant plastic and has a "trumpet mouth" structure (large opening facing up and small opening facing down) to expand the air blowing area. A duct 19 is installed below the air diffuser 18. One end of the duct 19 is fixedly connected to the small opening end of the air diffuser 18 by a thread, and the other end is connected to the air outlet of the blower 20 by a flange. The blower 20 is fixedly installed on the ground support and can provide a stable high-pressure airflow.

[0032] It should be noted that the specific models and specifications of hydraulic cylinder 4, air cylinder 14 and blower 20 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated. All of them can be powered by external equipment and controlled to open and close.

[0033] Working principle:

[0034] At the start of the process, the steel plate enters the inlet side of the installation platform 1 from the conveyor line, and is guided onto the roller 6 by the guide wheel 2; at the same time, the blowing and floating assembly 8 is activated: the cylinder 14 pushes the rectangular frame 16 down along the slide 15 to the predetermined height, and the blower 20 generates high-pressure airflow that is blown upward through the air duct 19 and the air expansion duct 18 to form a uniform air curtain, which lifts the front end of the steel plate to prevent it from sagging and ensures that the steel plate enters the receiving area smoothly.

[0035] The steel plate is conveyed to the fixed plate 5 with the aid of a buoyancy pump. At this time, the telescopic end of the hydraulic cylinder 4 is in the extended state. The fixed plate 5 is kept horizontal by the lifting frame 10 and the rotating block 11, and the roller 6 reduces friction, allowing the steel plate to slide in smoothly. Subsequently, the hydraulic cylinder 4 retracts, driving the connecting plate 9 and the lifting frame 10 to move upward, pulling the rotating block 11 to tilt the fixed plate 5 around the pin (0°-30°). The steel plate slides towards the stacking area due to gravity, completing the collection. The angle can be adjusted according to the thickness of the steel plate, and the limiting post 13 ensures the stable movement of the connecting plate 9.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
