Description

Technical Field

[0001] This utility model relates to the technical field of steel processing equipment, specifically to a hanging rail feeding device for large-size steel. Background Technology

[0002] In the production of steel and other metal components, raw metal materials are typically rolled into the desired shape, and then painted according to the steel's intended use and specific requirements. This process enhances the steel's durability and aesthetics. After painting, the steel usually undergoes a drying process to ensure the paint is completely dry. To improve the efficiency of steel transfer between processing stages, overhead rails are commonly used for transporting the steel throughout the various production steps.

[0003] For example, patent document CN107745929A discloses a steel plate aerial transport device. An elevated track is installed above the factory building, and a fixed loading and unloading mechanism is installed on the elevated track to install the steel plate. A cutting rail frame is installed on the factory floor, and a cutting machine is installed on the cutting rail frame. The steel plate is moved from the elevated track to the cutting rail frame, and then cut by the cutting machine. This invention provides a steel plate aerial transport device that uses an elevated track to transport steel plates, and also includes a projector to improve worker safety.

[0004] While the above-mentioned technical solutions can efficiently and safely transport steel plates at high altitudes, the steel production process often involves the production of many long steel products. In order to ensure that these steel products can be hoisted and transferred smoothly, the track is usually positioned at a high height. Furthermore, due to the length of the steel products, it is easy for the steel to be difficult to rotate during loading, and the steel is prone to collisions or scratches with surrounding equipment after loading, resulting in scratches or dents on the surface of the steel and affecting the quality of the steel. Utility Model Content

[0005] The present invention aims to provide a hanging rail feeding device for large-size steel materials, so as to solve the technical problems in the prior art where it is difficult to rotate steel materials and steel materials are prone to collision or scratching with surrounding equipment after being fed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a large-size steel loading device with a conveying rail, comprising a loading section, a loading platform provided in the loading section, and a lifting rail provided above one end of the loading platform; a hanger is provided on the lifting rail, the hanger being movable along the extension direction of the lifting rail; the loading platform is used to place steel, and the hanger is used to lift the steel on the loading platform; multiple drive chains are laid on the surface of the loading platform, the multiple drive chains are evenly distributed on the loading platform, and the extension direction of the drive chains is parallel to the extension direction of the lifting rail; the drive chains surround the circumference of the loading platform, and the drive chains are movable along the circumference of the loading platform.

[0007] The principle and advantages of this scheme are as follows: When feeding steel onto the hanging rail, the hanging rail is laid on the feeding platform along the direction perpendicular to the extension of the hanging rail, and one end of the steel is connected to the hanger on the hanging rail. The hanger drives the steel to move along the extension direction of the hanging rail. At the same time, the steel moves on the feeding platform along the extension direction of the hanging rail. When the steel moves outside the feeding rack, the steel layer is suspended above the hanging rail, thus completing the feeding operation of steel onto the hanging rail.

[0008] In this solution, a loading platform supports the steel during loading, ensuring its stability and preventing swaying or even collapse of the steel when it is hoisted onto the lifting rails due to its excessive length. Furthermore, the loading platform supports the end of the steel furthest from the lifting rails to prevent swaying during loading, ensuring stability and preventing collisions, thus guaranteeing the safety of the steel.

[0009] Furthermore, by laying a drive chain on the loading platform, the steel can move under the drive of the drive chain when it moves on the loading platform. This ensures that the position of the steel relative to the drive chain is stationary during the movement of the steel, and avoids sliding friction between the steel and the loading platform during the movement of the steel, which would cause wear on the surface of the steel and reduce the quality of the steel.

[0010] Preferably, as an improvement, the width of the top of the loading platform is greater than the width of the bottom of the loading platform, and both sides of the loading platform are designed as inclined surfaces. This allows the steel to be gradually raised or lowered under the influence of the slope on both sides of the loading platform when it is being transported to or from the loading platform, ensuring the stability of the steel as it moves on the loading platform and ensuring that the overall center of gravity of the loading platform is lower, thus ensuring the overall stability of the loading platform after the steel is placed on it.

[0011] Preferably, as an improvement, the area of ​​the lifting rail near the loading platform along the feeding direction extends downwards along the height direction; the area of ​​the lifting rail away from the loading platform along the feeding direction extends upwards along the height direction. This reduces the height of the area where the lifting rail loads materials, facilitating the loading operation and avoiding the need to lift the steel to a high position when loading the steel due to an excessively high loading platform, thus reducing the difficulty of the steel loading operation.

[0012] Preferably, as an improvement, the drive chain has multiple evenly distributed partition bars, which extend along the height direction away from the drive chain. These partition bars are used to separate the steel pieces on the drive chain. This allows the multiple steel pieces to be distributed orderly on the drive chain, preventing collisions between adjacent steel pieces. At the same time, the partition bars limit the position of the steel pieces on the drive chain, preventing slippage between the steel pieces and the drive chain, which could cause the end of the steel piece away from the hanger to fail to move synchronously with the drive chain, thus affecting the normal feeding of steel.

[0013] Preferably, as an improvement, a guide frame is provided on one side of the feeding section. One end of the guide frame is connected to the end of the feeding platform away from the hanging rail, and the other end extends towards the bottom of the hanging rail along the feeding direction. The guide frame is used to support the bottom of the steel. This ensures that from the time the steel is fed until it is completely suspended vertically, the end of the steel away from the hanging rail is supported by the guide frame, preventing the steel from swaying due to insufficient support at the bottom after leaving the feeding platform, thus ensuring the safety of steel feeding.

[0014] Preferably, as an improvement, the guide frame is provided with multiple rollers, which are evenly distributed on the surface of the guide frame. This allows the steel to slide on the guide frame via the rollers as it moves, reducing friction between the steel surface and the guide frame. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of the overhead rail loading device for large-sized steel materials in this embodiment of the present invention.

[0016] Figure 2 This is a top view of the loading platform in an embodiment of this utility model. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation methods: The reference numerals in the accompanying drawings include: feeding section 1, feeding rack 101, feeding platform 102, hanging rail 2, hanging frame 201, drive chain 3, dividing rod 301, guide frame 4, and roller 401.

[0018] As attached Figure 1As shown, a large-size steel loading device with a lifting rail 2 includes a loading section 1, and a lifting rail 2 is provided above the loading section 1. The lifting rail 2 is used for lifting and transferring steel, and the loading section 1 is used for connecting the steel to the lifting rail 2 for loading.

[0019] The loading section 1 includes a loading rack 101, with a loading platform 102 on top of the loading rack 101. The loading platform 102 is trapezoidal, meaning the width of the top of the loading platform 102 is greater than the width of the side of the loading platform 102 closest to the loading rack 101. Both sides of the loading platform 102 are inclined surfaces. The loading platform 102 is used to place the steel to be loaded. When the steel is conveyed to or exited from the loading platform 102, it can be gradually raised or lowered by the slope on both sides of the loading platform 102, ensuring the stability of the steel movement on the loading platform 102 and ensuring that the overall center of gravity of the loading platform 102 is lower, thus ensuring the overall stability of the loading platform 102 after the steel is placed on it.

[0020] The hanging rail 2 is located above one end of the loading platform 102, and the area of ​​the hanging rail 2 near the loading platform 102 along the feeding direction extends downwards along the height direction; the area of ​​the hanging rail 2 away from the loading platform 102 along the feeding direction extends upwards along the height direction, that is, the hanging rail 2 is U-shaped on one side of the loading platform 102. This allows the height of the area where the hanging rail 2 is used for loading to be lowered, which facilitates the loading operation of steel and avoids the loading platform 102 being too high, which would require lifting the steel to a higher position when loading steel, thus reducing the difficulty of the steel loading operation. Multiple hangers 201 are slidably connected to the hanging rail 2. The multiple hangers 201 are evenly distributed on the hanging rail 2, and the hangers 201 can move along the extension direction of the hanging rail 2. The specific structure of the hanging rail 2 and the hangers 201 is existing technology and will not be described in detail here.

[0021] As attached Figure 2As shown, multiple drive chains 3 are laid on the surface of the loading platform 102. These drive chains 3 are evenly distributed on the loading platform 102, and their extension direction is parallel to the extension direction of the hanging rail 2. The drive chains 3 surround the circumference of the loading platform 102 and can move along the circumference of the loading platform 102. The direction of movement of the drive chains 3 on the loading platform 102 is consistent with the direction of movement of the hanging rail 2. Specifically, drive wheels are rotatably connected to the corresponding positions of the drive chains 3 on both sides of the loading platform 102 via rotating shafts. The drive wheels are connected to the output shaft of a motor via a transmission shaft. The motor drives the drive wheels to rotate, and the drive wheels drive the transmission chains to move on the surface of the loading platform 102. The drive chains 3 are used to move the steel on the surface of the loading platform 102. This ensures that when the steel moves on the loading platform 102, it can move under the drive of the drive chain 3, ensuring that the position of the steel relative to the drive chain 3 remains stationary during the movement, and preventing sliding friction between the steel and the loading platform 102 during the movement, which would cause wear on the surface of the steel and reduce the quality of the steel.

[0022] Multiple separator bars 301 are provided on the side of the drive chain 3 away from the loading platform 102. These separator bars 301 are spaced apart along the extension direction of the drive chain 3. One end of each separator bar 301 is fixed to the drive chain 3 with bolts, and the other end extends along the height direction away from the drive chain 3. The separator bars 301 are used to separate the steel pieces on the drive chain 3. This allows the steel pieces to be distributed in an orderly manner on the drive chain 3, preventing collisions between adjacent steel pieces. At the same time, the separator bars 301 limit the position of the steel pieces on the drive chain 3, preventing slippage between the steel pieces and the drive chain 3. This would prevent the end of the steel piece away from the hanger 201 from moving synchronously with the drive chain 3, thus affecting the normal loading of the steel.

[0023] A guide frame 4 is provided on one side of the loading section 1. One end of the guide frame 4 is connected to the top of the loading platform 102 away from the hanging rail 2, and the other end extends towards the bottom of the hanging rail 2 along the feeding direction of the hanging rail 2. The guide frame 4 is used to support the bottom of the steel during loading, so that the end of the steel away from the hanging rail 2 can be supported by the guide frame 4 after loading until it is completely vertically suspended. This prevents the bottom of the steel from not being effectively supported after leaving the loading platform 102, which would cause the steel to sway and ensure the safety of steel loading. Multiple rollers 401 are rotatably connected to the guide frame 4 via rotating shafts. The rollers 401 are evenly distributed on the surface of the guide frame 4. The rollers 401 are inclined along the height direction on the surface of the guide frame 4, and the specific inclination angle of the rollers 401 matches the inclination angle of the steel on the guide frame 4 during loading. This allows the steel to slide on the guide frame 4 via the rollers 401 when moving on the guide frame 4, reducing the friction between the steel surface and the guide frame 4.

[0024] The specific implementation process is as follows: When feeding steel onto the hanging rail 2, the hanging rail 2 is laid on the loading platform 102 along the direction of its vertical extension. One end of the steel is connected to the hanger 201 on the hanging rail 2. The hanger 201 drives the steel to move along the direction of its extension. At the same time, the steel moves along the direction of its extension on the loading platform 102. When the steel moves outside the loading platform 101, the steel layer is suspended above the hanging rail 2, thus completing the feeding operation of steel onto the hanging rail 2.

[0025] Compared to existing technologies, this solution utilizes a loading platform 102 to support the steel during loading. This ensures the steel remains stable during loading, preventing excessive length from causing swaying or even collapse during hoisting onto the lifting rail 2, which could lead to damage. Furthermore, the loading platform 102 supports the end of the steel furthest from the lifting rail 2, preventing swaying during loading and ensuring stability and safety.

[0026] It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
