Description

Technical Field

[0001] This invention relates to the field of steel profile production and processing, and specifically to a steel profile stacking device and method. Background Technology

[0002] Section steel is a strip of steel with a specific cross-sectional shape and size. Complex section steel (irregular-shaped steel) includes H-beams, channel steel, rails, window frame steel, and bent steel. At the end of the section steel production process, the steel needs to be sawn according to dimensional requirements to remove any defective parts from the ends and obtain the required length.

[0003] Currently, in the production of H-beams or other similar H-beams, single steel sections are conveyed to the sawing station for cutting, resulting in low sawing efficiency. To improve sawing efficiency, before entering the sawing station, the steel sections are discharged from the cold pressing unit and then hoisted to one side of the conveyor line using hoisting equipment. The steel sections are then stacked, bound, hoisted onto the conveyor line, and transported to the sawing station, allowing two steel sections to be sawed simultaneously. Currently, there is a scheme where the hoisting equipment is erected above the conveyor line, clamping and lifting the steel sections before placing them on top of the subsequently conveyed steel sections for stacking. This scheme uses multiple sets of drive components, resulting in a complex structure. Furthermore, the clamping structure design is complex, employing various electrical control components such as electromagnets, electric lifting rods, and motors. The environment inside the steel production and processing plant is harsh, making these electrical control components susceptible to damage and malfunction due to environmental influences. Additionally, the electrical control components pose safety hazards such as electric shock and short circuits, making it difficult to guarantee safe operation over long periods. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a steel section stacking device and method. This method utilizes a parallelogram mechanism combined with a lever mechanism to clamp and lift the steel sections, creating a channel to avoid obstructing the transport of the next steel section. After releasing the steel sections, they are stacked to facilitate subsequent sawing of two steel sections. A single power source is used to achieve the clamping, lifting, releasing, and lowering processes of the stacked steel sections, reducing the structural complexity of the drive components and minimizing safety hazards associated with the use of electronic control components.

[0005] The first objective of this invention is to provide a steel section stacking device, which adopts the following solution:

[0006] The device includes a parallelogram mechanism, a crank, and a clamping mechanism. The clamping mechanism is mounted on a horizontally arranged connecting rod of the parallelogram mechanism. The clamping mechanism includes a fixed push rod and a movable push rod arranged opposite each other. The movable push rod is connected to the connecting rod through a sliding joint. One end of the crank is hinged to a telescopic drive rod, and the other end is connected to the movable push rod. The middle of the crank is rotatably connected to the pivot of a connecting rod in the parallelogram mechanism. The telescopic drive rod drives the crank to drive the clamping mechanism to clamp or release, and drives the connecting rod to swing through the pivot to make the clamping mechanism rise or fall.

[0007] Furthermore, one end of the crank is connected to a movable push rod via a transmission rod, and the end of the movable push rod near the fixed push rod forms a clamping part of variable width with the fixed push rod to clamp or release the steel profile.

[0008] Furthermore, the movable pair includes a sliding support with a guide groove and a guide wheel that cooperates with the guide groove, and a movable push rod is connected to the guide wheel.

[0009] Furthermore, the clamping part of the clamping mechanism is arranged at intervals with the connecting rod, and a channel is formed between the clamping part and the connecting rod for other steel sections to pass through.

[0010] Furthermore, the fixed top rod end is rotatably connected to a first movable block for contacting the steel profile, and the movable push rod end is rotatably connected to a second movable block for contacting the steel profile. The first and second movable blocks can release the steel profile by rotation.

[0011] Furthermore, the crank is provided with three sets of through holes arranged in sequence. One set of through holes is rotatably connected to the telescopic drive rod, another set of through holes is rotatably connected to the movable push rod, and the through hole in the middle is matched with the rotating shaft.

[0012] Furthermore, the parallelogram mechanism includes a connecting rod hinged to the frame and connecting rods connected to the connecting rod at both ends; when the rotating shaft drives the connecting rod to swing, the relative angle between the crank connected to the same rotating shaft and the connecting rod remains unchanged.

[0013] Furthermore, it also includes a conveying mechanism, which comprises multiple conveying rollers arranged at intervals, with the top of the conveying rollers forming a conveying surface that carries and conveys the steel profile, and a parallelogram mechanism, a crank, and a clamping mechanism located between two adjacent conveying rollers.

[0014] A second objective of this invention is to provide a method of operation for using the above-mentioned steel section stacking device, comprising:

[0015] The telescopic drive rod moves the movable push rod via a crank to approach the fixed top rod, contact and clamp the steel section one;

[0016] The telescopic drive rod continues to extend, driving the crank arm to swing the connecting rod through the pivot. The movable push rod keeps clamping the steel section one, and the clamping mechanism and the steel section one are lifted through the connecting rod, forming a channel between the steel section one and the connecting rod.

[0017] After passing through the channel, the second section of steel is located below the first section of steel. The telescopic drive rod retracts, and during the process of lowering the first section of steel, the movable push rod gradually moves away from the fixed top rod until the first section of steel is released and falls above the second section of steel.

[0018] After being stacked, steel section one and steel section two are transported together. The telescopic drive rod retracts, causing the connecting rod and crank arm to return to their initial positions, waiting for the next steel section to be stacked.

[0019] Furthermore, during the process of the telescopic drive rod retracting and lowering the first steel section, the bottom surface of the first steel section contacts the second steel section, the first steel section stops lowering, and the clamping mechanism continues to fall back to the initial position; the second steel section is located directly below the position where the first steel section is released.

[0020] Compared with the prior art, the advantages and positive effects of this invention are:

[0021] (1) In view of the current problems of complex structure of steel section stacking and poor reliability of electrical control components, the steel section is clamped and lifted by a combination of parallelogram mechanism and lever mechanism, forming a channel to avoid the conveying of the next steel section. After the steel section is released and dropped, the steel section is stacked so that the two steel sections can be sawed together in the future. A single power source is used to realize the clamping, lifting, releasing and dropping process of steel section stacking, reducing the structural complexity of the drive components and reducing the safety hazards caused by the use of electrical control components.

[0022] (2) The crank acts as the power source for clamping and releasing the clamping mechanism. It drives the movable push rod to move back and forth, thereby moving closer to or further away from the fixed top rod and changing the size of the clamping part. At the same time, the crank also acts as the power source for the parallelogram mechanism to raise and lower the connecting rod. The crank drives the connecting rod to swing through the rotating shaft, changing the position of the steel section clamped by the clamping mechanism on the connecting rod, so that the steel section can be located above the original conveying position, meeting the requirements for falling and stacking after the clamping mechanism is released. The combined mechanism enables a single power source to complete different actions at different motion trajectories, reducing the complexity of the drive structure.

[0023] (3) A clamping part is formed between the fixed top rod and the movable push rod. The ends of the rods abut against the flanges of the steel section to achieve stable clamping of the steel section. A channel is reserved between the clamping part and the connecting rod for the next steel section to pass through, avoiding the steel section conveying path, facilitating the subsequent conveying and stacking of the steel section, and improving the conveying and stacking efficiency.

Detailed Implementation

[0037] Example 1

[0038] In a typical embodiment of the present invention, such as Figures 1-11As shown, a steel section stacking device is presented.

[0039] Production efficiency can be improved by stacking and sawing steel sections 7, but manual stacking is inefficient. Currently, the equipment used for stacking is quite complex, with clamping and lifting structures, requiring multiple power sources and corresponding frames, resulting in a complex overall structure. Some actions require the use of electrical control components, but the environment inside the steel section 7 production and processing plant is harsh, making the electrical control components susceptible to damage and malfunction. Furthermore, the electrical control components pose safety hazards such as electric shock and short circuits, making it difficult to guarantee safe operation over a long period.

[0040] Based on this, this embodiment provides a steel section stacking device, which realizes the lifting and lowering of the steel section at position 7 through the linkage of a parallelogram mechanism and a lever mechanism. It uses a single power source to meet the action requirements of stacking, reduces the use of drive components, simplifies the mechanism and saves electrical control components, thereby improving the safety of the equipment in harsh environment workshops, reducing safety hazards and improving stacking efficiency.

[0041] The steel stacking device in this embodiment will now be described in detail with reference to the accompanying drawings.

[0042] See Figure 1 The steel section stacking device mainly includes a parallelogram mechanism, a crank 2, and a clamping mechanism. The parallelogram mechanism serves as the main load-bearing element. The crank 2 and the clamping mechanism are respectively installed on the parallelogram mechanism. After the crank 2 is connected to the clamping mechanism, it can drive the clamping mechanism to clamp or release the steel section 7. After the crank 2 is connected to the parallelogram mechanism, it can drive the connecting rod 1 of the parallelogram mechanism to swing, thereby driving the connecting rod 3 to rise and fall.

[0043] The clamping mechanism is mounted on the connecting rod 3, which can rise and fall. The crank 2 can drive the clamping mechanism and the parallelogram mechanism. The movement of the crank 2 is achieved by the extension and retraction of the telescopic drive rod 10, thereby using a single power source to achieve the clamping, rising and releasing of the steel section 7. At the same time, it can drive the parallelogram mechanism to return to its original position, waiting for the next steel section 7 to be placed.

[0044] It is understandable that the steel section 7 is conveyed via the conveying mechanism 11. The conveying mechanism 11 can transport the steel section 7 from upstream to the clamping position, and can also transport the stacked steel section 7 together to the downstream sawing station. Figure 1 , Figure 2 The conveying mechanism 11 is located in the area that does not interfere with the operation of the parallelogram mechanism and the clamping mechanism.

[0045] In this embodiment, the conveying mechanism 11 includes multiple conveying rollers arranged at intervals, and the top of the conveying rollers forms a conveying surface that carries and conveys the steel section 7, such as... Figure 8 As shown, the steel section 7 to be clamped is pushed and clamped by the clamping mechanism on the conveying surface, which can also bear and transport the stacked steel section 7.

[0046] To avoid interference during clamping, lifting and releasing actions, the parallelogram mechanism, crank 2 and clamping mechanism are located between two adjacent conveyor rollers, avoiding the area where the conveyor rollers are located, and can perform corresponding operations on the steel section 7 from between the conveyor rollers.

[0047] A parallelogram mechanism includes a frame, connecting rod 1, and connecting rod 3. It is a typical four-bar linkage and can be implemented using either a double-rocker mechanism or a double-crank mechanism. For example... Figure 4 As shown, the range of motion is limited during the stacking process of the steel section 7. The reciprocating swing motion of the connecting rod 1 can meet the requirements of the entire workflow.

[0048] The clamping mechanism is mounted on the connecting rod 3. In order to facilitate the clamping of the horizontally conveyed steel section 7, the connecting rod 3 is kept in a horizontal state. The connecting rod 3 is driven by the connecting rod 1 to keep it moving horizontally, so that the clamping mechanism mounted on it is kept in a horizontal state. When the clamping part provided on the clamping mechanism can clamp the steel section 7 horizontally, it will drive the steel section 7 to move while keeping it in a horizontal state.

[0049] The clamping mechanism includes a fixed top rod 8 and a movable push rod 6 arranged opposite to each other. The movable push rod 6 is connected to the connecting rod 3 through a sliding joint. Under the constraint of the sliding joint, the movable push rod 6 can move closer to or away from the fixed top rod 8. The end of the movable push rod 6 that is closer to the fixed top rod 8 forms a clamping part with a variable width between it and the fixed push rod to clamp or release the steel section 7.

[0050] One end of the crank 2 is hinged to the telescopic drive rod 10, and the other end drives the movable push rod 6 to move. The middle part of the crank 2 is rotatably connected to the pivot 15 of the connecting rod 3 of the connecting rod 1 in the parallelogram mechanism. Since the crank 2 rotates relative to the pivot 15, the crank 2 drives the movable push rod 6 to move in an arc trajectory. In order to realize the linear trajectory motion of the movable push rod 6 under the movement constraint, a transmission rod 5 is set between the crank 2 and the movable push rod 6. One end of the crank 2 is connected to the movable push rod 6 through the transmission rod 5, thereby converting the arc trajectory motion of the end of the crank 2 into the linear trajectory motion of the movable push rod 6.

[0051] Figure 3 and Figure 4 The image shows the state of the clamping mechanism when it is clamping the steel section 7. The movable push rod 6 moves from the right to the left until the movable push rod 6 and the fixed top rod 8 clamp the steel section 7 together, thus completing the clamping action.

[0052] Both the clamping and releasing actions are achieved through the translational movement of the movable push rod 6. For the sliding pair, a sliding support 4 with a guide groove and a guide wheel that engages with the guide groove are used. The guide wheel slides within the guide groove, which is elongated, thus causing the guide wheel to drive the movable push rod 6 to translate. Figure 6 , Figure 7 As shown. The fixed top rod 8 is installed on the connecting rod 3 through the fixed support 9, so that the fixed top rod 8 and the movable push rod 6 remain opposite each other. In this embodiment, the fixed top rod 8 and the movable push rod 6 are arranged coaxially.

[0053] In other embodiments, the sliding pair can be a slider with a groove structure or a sleeve with a slide rod structure, arranged according to the space on site, to achieve translational drive of the movable push rod 6.

[0054] Understandably, the sliding support 4 is located above the connecting rod 3. To facilitate the arrangement of the crank 2, a clearance hole 14 is provided on the connecting rod 3, allowing the crank 2 to pass through the connecting rod 3 and connect to the transmission rod 5, as shown below. Figure 8 As shown, the opening size of the clearance hole 14 is determined so as not to interfere with the movement of the crank 2.

[0055] For the movable push rod 6 and the fixed push rod 8 that form the clamping mechanism, combined with Figure 8 and Figure 9 Both the movable push rod 6 and the fixed push rod 8 have a gradient section structure on the side of the steel profile 7 that adapts to the clamping part. The top and side are smoothly transitioned, which can reach into the flange plate of the steel profile 7 and reduce the scratch damage of the steel profile 7.

[0056] The telescopic drive rod 10 drives the crank 2 to clamp or release the clamping mechanism, and through the rotating shaft 15, it drives the connecting rod 1 to swing, causing the clamping mechanism to rise or fall. Figure 1 , Figure 6 As shown, the clamping part of the clamping mechanism is arranged at intervals with the connecting rod 3, and a channel is formed between the clamping part and the connecting rod 3 for other steel sections 7 to pass through. After the steel section 7 is lifted, the channel is coaxial with the trajectory of the next steel section 7, so as to avoid collision with the steel section stacking device during the placement of the next steel section 7.

[0057] The fixed push rod end is rotatably connected to a first movable block 16 for contacting the steel profile, and the movable push rod end is rotatably connected to a second movable block 17 for contacting the steel profile. The first movable block 16 and the second movable block 17 can release the steel profile by rotation. The first movable block 16 and the second movable block 17 can rotate, and when the clamped steel profile contacts the lower steel profile and no longer falls, the first movable block 16 and the second movable block 17 rotate to release the clamping action. Figure 4 As shown, rotate upwards to avoid the steel section and then return to the original position, waiting for the next clamping action, as... Figure 3 As shown.

[0058] During the retraction and lowering of section 12 by the telescopic drive rod, the bottom surface of section 12 contacts section 23, section 12 stops lowering, and the clamping mechanism continues to fall back to the initial position; section 23 is located directly below the position where section 12 is released.

[0059] Combination Figure 1 , Figure 3 and Figure 6 The telescopic drive rod 10 drives the clamping mechanism and the parallelogram mechanism to move. The telescopic drive rod 10 can extend or shorten along its axial direction, and the entire stacking process is realized through this telescopic movement. One end of the telescopic drive rod 10 is hinged to the base, and the other end is connected to the crank 2.

[0060] The telescopic drive rod 10 can use a hydraulic cylinder commonly used in the processing plant area and be connected to the hydraulic power source in the plant area. Compared with electric actuators and other electric drive equipment, it can improve the safety of the entire device. At the same time, the output range of the hydraulic cylinder is adjustable, which can meet the needs of various types of steel 7.

[0061] The crank 2, acting as a lever structure, can drive the clamping mechanism when the pivot 15 is used as the fulcrum. After completing the clamping action, it drives the entire parallelogram mechanism to move, using the hinged frame position of the connecting rod 1 as the fulcrum. The crank 2 has three sets of through holes arranged in sequence. One set of through holes is rotatably connected to the telescopic drive rod 10, another set of through holes is rotatably connected to the movable push rod 6, and the through hole in the middle is matched with the pivot 15.

[0062] The structure of crank 2 is as follows Figure 10 and Figure 11 As shown, it includes two sets of lugs and a support rod. One set of lugs is located on one side of the support rod axis and is used to connect the rotating shaft 15 and the transmission rod 5. The other set is located on the other side of the support rod and is used to connect the telescopic drive rod 10. When the rotating shaft 15 drives the connecting rod 1 to swing, the relative angle between the crank 2 connected to the same rotating shaft 15 and the connecting rod 1 remains unchanged.

[0063] The crank 2 serves as the power source for the clamping mechanism to perform clamping and releasing actions. By driving the movable push rod 6 to reciprocate, it moves closer to or further away from the fixed top rod 8, changing the size of the clamping part. At the same time, the crank 2 also serves as the power source for the parallelogram mechanism to perform the rising and falling actions of the connecting rod 3. Through the rotating shaft 15 that cooperates with the crank 2, it drives the connecting rod 1 to swing, changing the position of the steel section 7 clamped by the clamping mechanism on the connecting rod 3, so that the steel section 7 can be located above the original conveying position, meeting the falling and stacking requirements after the clamping mechanism is released. By using the combined mechanism, a single power source can complete different actions at different motion trajectories, reducing the complexity of the drive structure.

[0064] Example 2

[0065] In another typical embodiment of the present invention, such as Figures 1-11 As shown, a working method for using a steel stacking device is presented.

[0066] Combination Figures 1-11 The working method, using the steel stacking device as described in Example 1, includes:

[0067] The telescopic drive rod 10 drives the movable push rod 6 to move closer to the fixed push rod 8 via the crank 2. Figure 2 As shown; contact and clamp section steel 12, as Figure 4 As shown;

[0068] As the movable push rod 6 approaches the fixed top rod 8, the movable push rod 6 pushes the steel section 12 to approach and contact the fixed top rod 8;

[0069] The telescopic drive rod 10 continues to extend, driving the crank arm to swing the connecting rod 1 through the pivot 15. The movable push rod 6 keeps clamping the profile 12, and drives the clamping mechanism and profile 12 to be lifted through the connecting rod 3, forming a channel between profile 12 and connecting rod 3.

[0070] After section 2 (13) passes through the channel, it is positioned below section 1 (12). The telescopic drive rod retracts, and during the lowering of section 1, the movable push rod gradually moves away from the fixed top rod until section 1 is released and falls above section 2. Figure 6 As shown;

[0071] The stacked steel section 12 and steel section 2 13 are transported together. The telescopic drive rod 10 retracts, driving the connecting rod 3 and the crank arm to return to their initial positions, waiting for the next steel section 7 to be stacked.

[0072] It is understandable that by setting up a first movable block and a second movable block, and by enabling the first movable block 16 and the second movable block 17 to rotate, the clamping action is released when the clamped steel section contacts the lower steel section and stops falling. Figure 4 As shown, rotate upwards to avoid the steel section and then return to the original position, waiting for the next clamping action, as... Figure 3 As shown. During the retraction and lowering of section 12 by the telescopic drive rod, the bottom surface of section 12 contacts section 23, section 12 stops lowering, and the clamping mechanism continues to fall back to the initial position; section 23 is located directly below the position where section 12 is released.

[0073] The parallelogram mechanism combined with the lever mechanism is used to clamp and lift the steel section 7, forming a channel to avoid the conveying of the next steel section 7. After the steel section 7 is released and dropped, it is stacked to facilitate the subsequent sawing of two steel sections 7. A single power source is used to realize the clamping, lifting, releasing and dropping process of the stacked steel sections 7, reducing the structural complexity of the drive components and reducing the safety hazards caused by the use of electronic control components.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
