Description

Technical Field

[0001] This utility model relates to the field of coal mine support engineering technology, and more specifically, to a system for producing I-beam shed beams. Background Technology

[0002] In underground coal mine working faces, layered mining is a widely used coal mining method. It involves mining coal seams in layers of a certain thickness, layer by layer, to achieve effective utilization of coal resources and control ground pressure. Layered mining allows coal mines to manage roof pressure more precisely, thereby improving mining safety and efficiency. However, layered mining also brings complexity to roof management, especially during tunnel excavation, where the reliability of roof support is one of the key factors in ensuring safe production.

[0003] To ensure the reliability of roof support, coal mines typically use trapezoidal metal supports made of mining I-beams for roof support. These trapezoidal metal supports are constructed using I-beams, which are usually cut to specific lengths and have welded beams at both ends to secure the support legs and prevent displacement under roadway pressure. This support structure design provides sufficient support to resist the pressure of surrounding rock and soil, while also adapting to the irregular shape of the roadway, ensuring the stability and safety of the coal mine roadway.

[0004] However, the traditional manufacturing process of I-beam shed beams relies heavily on manual operation. Currently, the use of manual gas cutting and welding of I-beam shed beam claws has the following problems: 1. The workload is heavy and the labor intensity is high; 2. There are errors in the position and size of manual welding, and the welding quality decreases with the intensity of work, which affects the support operation of underground roadways; 3. High-intensity and long-term welding operations pose hazards to the occupational health of workers (welding fumes, arc light, high temperature, etc.).

[0005] There is currently no effective solution to the above problems. Utility Model Content

[0006] The main objective of this invention is to provide a system for producing I-beam shed beams, in order to solve the problem of low work efficiency caused by manual welding of I-beam shed beams in the prior art.

[0007] To achieve the above objectives, according to one aspect of the present invention, a system for producing I-beam girders is provided, comprising: a girder welding device, the girder welding device including a welding platform and a base frame, the base frame being connected to the welding platform, the base frame having a first bearing area for bearing the girder to be welded and the beam claw to be welded, a first positioning device for positioning the girder to be welded on the base frame, a second positioning device for positioning the beam claw to be welded on the base frame, and a first roller being provided on at least one of the welding platform and the base frame, the first roller being used to drive the girder to be welded and the beam claw to be welded to be movably positioned relative to at least one of the welding platform and the base frame.

[0008] Furthermore, the basic frame extends along the first direction, and multiple feeding troughs are provided on the basic frame. The multiple feeding troughs are spaced apart along the first direction, and each feeding trough is a sink trough. Each feeding trough extends along the second direction, and each feeding trough forms a reserved working space for the fork teeth.

[0009] Furthermore, the first positioning device includes a horizontal positioning device, which is located on the top of the foundation frame. The horizontal positioning device includes: two side plates, which are respectively located on both sides of the foundation frame along the second direction; and multiple spacers, which are spaced apart between the two side plates along the second direction. Adjacent spacers and adjacent spacers and side plates form beam channels. During the process of the first roller driving the beam to be welded to move, the beam to be welded is located in the beam channel.

[0010] Furthermore, the first positioning device also includes a lifting limit device, which is located on the side of the foundation frame away from the welding platform. The lifting limit device includes a power component and a lifting plate connected to the power component. The power component is used to drive the lifting plate to move in the vertical direction. The lifting plate has a limit position that moves to a predetermined distance protruding from the top plane of the foundation frame. When the lifting plate is in the limit position, the end of the beam to be welded abuts against the lifting plate.

[0011] Furthermore, the second positioning device includes an infrared positioning instrument, which is disposed on one side of the foundation frame along the second direction and is used to position the beam claws to be welded.

[0012] Furthermore, the first direction and the second direction are perpendicular.

[0013] Furthermore, the I-beam shed beam production system includes an oxy-fuel cutting device, which includes an oxy-fuel cutting loading platform and an oxy-fuel cutting robot. The oxy-fuel cutting robot is used to cut the material to be cut on the oxy-fuel cutting loading platform into at least one of beam claws and stiffening plates.

[0014] Furthermore, the gas cutting loading platform has a second carrying area for carrying materials, and a second roller is provided on the gas cutting loading platform. The second roller is used to move the materials from the second carrying area to the processing position.

[0015] Furthermore, the gas cutting loading platform includes a rib cutting mold, which is located on the side of the gas cutting loading platform near the gas cutting robot. When the second roller drives the material to abut the rib cutting mold, the material is in the rib processing position.

[0016] Furthermore, the gas cutting loading platform includes a beam claw cutting mold, which is detachably connected to the rib plate cutting mold. When the second roller drives the material to abut against the beam claw cutting mold, the material is in the beam claw processing position.

[0017] By applying the technical solution of this utility model, the precise alignment of the components to be welded is ensured through the first and second positioning devices, reducing manual intervention. The rotation of the first roller enables automatic feeding and positioning of the beam and beam claws to be welded, allowing them to move relative to the welding platform or foundation frame during the welding process, achieving automated welding. This design significantly improves welding efficiency and accuracy while reducing the labor intensity of operators and enhancing welding safety and reliability. It solves the problem of low work efficiency in the existing technology of manually welding I-beam beams. Attached Figure Description

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0029] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a system for producing I-beam roof beams is provided.

[0030] Specifically, the system for producing I-beam girders includes: a girder welding device, which includes a welding platform 1 and a base frame 2. The base frame 2 is connected to the welding platform 1. The base frame 2 has a first bearing area for bearing the girder 3 to be welded and the beam claw 4 to be welded. The base frame 2 has a first positioning device for positioning the girder 3 to be welded and a second positioning device for positioning the beam claw 4 to be welded. At least one of the welding platform 1 and the base frame 2 is provided with a first roller 5, which is used to drive the girder 3 to be welded and the beam claw 4 to be welded to be movably positioned relative to one of the welding platform 1 and the base frame 2.

[0031] By applying the technical solution of this utility model, the precise alignment of the components to be welded is ensured through the first and second positioning devices, reducing manual intervention. The rotation of the first roller 5 enables automatic feeding and positioning of the beam 3 and the beam claw 4 to be welded, allowing them to move relative to the welding platform 1 or the base frame 2 during the welding process, achieving automated welding. This design significantly improves welding efficiency and accuracy while reducing the labor intensity of operators and enhancing welding safety and reliability. It solves the problem of low work efficiency in the existing technology of manually welding I-beam beams.

[0032] Specifically, the basic frame 2 extends along a first direction, and multiple feeding troughs 6 are provided on the basic frame 2. These feeding troughs 6 are spaced apart along the first direction, and each feeding trough 6 is a settling trough. Each feeding trough 6 extends along a second direction, and each feeding trough 6 forms a reserved working space for the forklift teeth. The layout of the feeding troughs 6 optimizes the material conveying process, improves the flexibility and efficiency of the production line, and allows for rapid adjustments, especially when handling I-beams of different lengths, to meet diverse production needs. Through the design of reserved working space for the forklift teeth, the production line can easily adapt to the operation of various forklifts and automated handling equipment, not only increasing the speed of material handling 18 but also ensuring the safety of the handling process and reducing material damage and production delays caused by improper handling.

[0033] like Figure 3 As shown, the first direction is the length direction. In this embodiment, the dimensions of the basic frame 2 are designed to be 5200mm long, 1550mm wide, and 800mm high to meet the working requirements. The frame is welded from high-strength 11# I-beams and 12# channel steel to ensure the stability and load-bearing capacity of the structure. The upper part of the basic frame 2 is covered with a 4mm thick steel plate to form the platform cover, which serves as the welding platform 1.

[0034] Two loading troughs 6 are installed on the base frame 2, spaced apart along the length of the base frame 2. Each loading trough 6 is 220mm wide, and the distance between the two loading troughs 6 is 800mm. Each loading trough 6 is a recessed structure, meaning the opening is lower than the surface of the base frame 2. This design facilitates the placement and removal of materials and reduces shaking and displacement of materials during transportation. A second direction is perpendicular to the first direction, which is the width direction of the base frame 2. Each loading trough 6 extends along the second direction, meaning it runs through the width of the base frame 2, allowing forklift forks to accurately insert into these reserved spaces, thus enabling rapid and safe loading of the I-beam steel beams.

[0035] It should be further explained that multiple mounting slots are set on the welding platform 1, with the multiple mounting slots spaced apart along the first direction and each mounting slot extending along the second direction. The dimensions of the mounting slots are 1450mm in length and 138mm in width, and they are used to install the first roller 5. The first roller 5 is a roller with a length of 1420mm and a diameter of 138mm. The distance between two adjacent first rollers 5 in the first direction is 650mm. The pin holes of each first roller 5 must be ensured to be on the same horizontal level, with an error not exceeding ±1mm. The precise horizontal alignment of the pin holes can ensure that the first roller 5 is in a completely horizontal state after installation, which is a prerequisite for achieving smooth movement and accurate positioning of the workpiece.

[0036] Specifically, the first positioning device includes a horizontal positioning device 7, which is disposed on the top of the base frame 2, such as... Figure 4 As shown, the horizontal positioning device 7 includes: side plates 8 and spacers 9. There are two side plates 8, respectively positioned on both sides of the base frame 2 along the second direction; there are multiple spacers 9, spaced apart along the second direction between two side plates 8. Adjacent spacers 9 and adjacent spacers 9 and side plates 8 form beam channels 10. During the movement of the beam to be welded 3 driven by the first roller 5, the beam to be welded 3 is located within the beam channels 10. The structural design of the side plates 8 and spacers 9 of the horizontal positioning device 7, combined with the automated drive of the first roller 5, achieves high-precision positioning and high-efficiency processing of the beam to be welded 3 during the welding process, significantly improving welding quality and production efficiency, while reducing the labor intensity and safety hazards of manual operation.

[0037] The horizontal positioning device 7 is set on the top of the base frame 2, ensuring that the beam 3 to be welded can be accurately positioned on the top of the base frame 2 before welding, thereby providing a stable welding reference for the welding robot.

[0038] The length of the side plate 8 matches the length of the foundation frame, and its height is sufficient to prevent lateral displacement of the beam 3 to be welded during the welding process. The design of the side plate 8 not only defines the lateral boundary of the beam 3 to be welded, but also provides support to ensure the stability of the beam 3 to be welded during the welding process.

[0039] The beam channel 10 is formed by adjacent partitions 9 or by partitions 9 and side plates 8. The size and position of the partitions 9 are carefully calculated to ensure that they can work together with the side plates 8 to form multiple beam channels 10. The width and length of each beam channel 10 are matched with the size of the beam 3 to be welded, which ensures the smooth passage of the beam and provides precise positioning, preventing unnecessary movement of the beam during welding, which would affect welding quality and production efficiency. Driven by the first roller 5, the beam 3 to be welded moves along the beam channel 10 until it reaches the welding position, ensuring the stability and positioning accuracy of the beam 3 to be welded during the welding process.

[0040] Furthermore, the first positioning device also includes a lifting and limiting device 11, which is located on the side of the base frame 2 away from the welding platform 1. The lifting and limiting device 11 includes a power component and a lifting plate 12 connected to the power component. The power component drives the lifting plate 12 to move vertically. The lifting plate 12 has a limiting position that moves to a predetermined distance protruding from the top plane of the base frame 2. When the lifting plate 12 is in the limiting position, the end of the beam 3 to be welded abuts against the lifting plate 12. Through the precise control of the lifting and limiting device 11, the vertical positioning of the beam 3 to be welded before welding is achieved, avoiding displacement during the welding process and improving welding quality and production efficiency.

[0041] The lifting and limiting device 11 is installed below the welding platform 1. Before the end of the beam 3 to be welded reaches the welding position, the lifting and limiting device 11 vertically positions and limits it. The lifting plate 12 is driven vertically by a power component to ensure the vertical positioning accuracy of the beam 3 to be welded. When the lifting plate moves to the limiting position, its upper surface protrudes from the top plane of the base frame by a preset distance. This preset distance is not fixed and is preset according to the size of the workpiece. It is necessary to ensure that when the first roller 5 drives the end of the beam 3 to be welded to abut against the lifting plate 12, it can provide sufficient abutment force to prevent vertical displacement of the beam 3 during the welding process.

[0042] The power component of the lifting limit device 11 can be an electric motor, a pneumatic cylinder, or a hydraulic cylinder, which provides the power for the vertical movement of the lifting plate 12. The power component is connected to the lifting plate 12 through a connecting component (such as a connecting rod or a gear and rack mechanism), which can precisely control the vertical movement of the lifting plate 12 and ensure that it can be accurately positioned at the limit position when needed.

[0043] In this embodiment, the precise control and stable positioning function of the lifting limit device 11, combined with the automated components of the horizontal positioning device 7 and the first roller 5, together constitute a high-precision welding positioning for the beam 3 to be welded.

[0044] Specifically, the second positioning device includes an infrared positioning device 13, which is positioned on one side of the foundation frame 2 along the second direction. The infrared positioning device 13 is used to position the beam claws 4 to be welded. The application of the infrared positioning device 13 makes the positioning of the beam claws 4 to be welded more accurate and faster, reduces welding defects caused by inaccurate positioning, improves the overall quality of the I-beam truss beam, and also reduces the energy consumption of the production line. Precise positioning reduces material waste and rework, significantly improving production speed and reducing labor costs.

[0045] like Figure 1 As shown, three infrared positioning device 13 mounting bases are welded to one side of the welding platform 1 along the second direction using steel plates. The infrared positioning device 13 is fixed on the required mounting base, which is suitable for welding requirements of beam claws 4 of different sizes. The height of the infrared positioning device 13 is aligned with the upper edge of the beam claw 4 to be welded, ensuring that the infrared positioning device 13 can accurately detect the position of the beam claw 4 to be welded.

[0046] The infrared positioner 13 detects the position of the beam claw 4 to be welded by emitting infrared beams and receiving reflected signals, ensuring accurate alignment between the beam claw 4 and the welding point of the beam 3 during welding. Typically, the infrared positioner 13 is connected to a control system, which adjusts the welding robot's posture and welding trajectory by providing real-time feedback on the position information of the beam claw 4, ensuring welding accuracy.

[0047] In an optional embodiment, when the beam 3 to be welded is driven to the limit position by the first roller 5, the infrared positioning device 13 starts working, emitting an infrared beam to detect the beam claw 4 to be welded on the beam. The infrared positioning device 13 can detect the edge of the beam claw 4 to be welded and calculate the precise position of the beam claw 4 relative to the welding platform 1 based on the reflected signal. After obtaining the position information of the beam claw, the infrared positioning device 13 transmits the data to the welding robot or control system wirelessly or via wired means, ensuring that the welding robot can adjust the posture of the welding gun and the welding trajectory according to the real-time position information of the beam claw 4 to be welded. After completing the position adjustment, the welding robot begins to perform the welding task, performing precise welding according to the adjusted welding trajectory, ensuring welding quality and production efficiency.

[0048] Specifically, the first direction and the second direction are perpendicular. By setting the first direction as the length direction of the base frame 2, i.e., the feed or movement direction of the workpiece, and the second direction as a positioning reference perpendicular to the feed direction, it can be ensured that the workpiece is accurately positioned and guided in multiple dimensions. The first roller 5 in the first direction drives the workpiece forward, while the positioning device in the second direction (such as the horizontal positioning device 7 and the infrared positioning device 13) accurately positions the workpiece along the width direction. This vertical arrangement can improve the positioning accuracy and stability of the workpiece on the production line.

[0049] The perpendicular setting of the first and second directions allows positioning and guidance to be performed independently. Different workpieces on the production line may have differences in length and width. The positioning device in the second direction can be flexibly adjusted according to the width of the workpiece without affecting the normal feeding of the workpiece along the first direction. This allows the equipment to adapt to workpieces of different sizes and shapes, improving the flexibility and production capacity of the production line.

[0050] In this embodiment, the entire welding process consists of a STEP / SA-1800 robot, an inverter-type pulsed gas shielded welding machine, an SRC2.7S electrical control box, and a Spad-k8 teach pendant. The welding robot is mounted on the base of welding platform 1 and reliably fixed. Communication between the robot and the welding machine is achieved through digital I / O and analog I / O connections to the welding machine's input / output terminals. The welding configuration interface of the teach pendant is used to associate welding signals such as gas supply, wire feeding, and arc stabilization, and to configure the proportional relationship between the physical and logical values ​​of welding current and voltage. The robot will automatically adjust the welding torch's posture and welding speed based on the signal transmission information to perform precise welding operations.

[0051] Furthermore, the I-beam beam production system includes an oxy-fuel cutting device, which comprises an oxy-fuel cutting loading platform 14 and an oxy-fuel cutting robot. The oxy-fuel cutting robot is used to cut the material 18 to be cut on the oxy-fuel cutting loading platform 14 into at least one of beam claws and stiffening plates. Automated cutting using an oxy-fuel cutting robot can significantly improve cutting speed and accuracy, reduce manual intervention, reduce material waste, and improve cutting efficiency.

[0052] The gas cutting loading platform 14 is the initial stage of the I-beam girder production line. Its main function is to receive the I-beam girder to be processed, providing a stable working platform for the gas cutting robot. The gas cutting robot first needs to position the material 18 to be cut placed on the loading platform 14. This is usually accomplished through a vision system or sensors, ensuring that the material 18 is in the correct position before cutting for precise cutting. After positioning, the gas cutting robot automatically executes the cutting action according to the preset cutting program (which includes information such as cutting trajectory, speed, and gas cutting parameters). The gas cutting robot can flexibly adjust the position and posture of the cutting head, cutting the material 18 into beam claws and stiffening plates.

[0053] like Figure 2 As shown, based on the overall mechanical rigid frame design, the foundation frame 2 of the gas cutting loading platform 14 is constructed by welding 11# I-beams and 12# channel steel. The frame dimensions are 2250mm in length, 910mm in width, and 800mm in height. A 4mm thick steel plate is laid on top of the foundation frame 2 to form the platform cover for the gas cutting loading platform 14. A groove 460mm long and 100mm wide is cut from the steel plate using gas cutting for installing the second roller 16.

[0054] Specifically, the gas cutting loading platform 14 has a second carrying area for carrying materials 18, and a second roller 16 is provided on the gas cutting loading platform 14. The second roller 16 is used to move the materials 18 from the second carrying area to the processing position. The setting of the second roller 16 optimizes the material conveying process, reduces manual handling, and improves the automation level and safety of the production line.

[0055] The surface of the second bearing area is typically covered with wear-resistant steel plates or materials to improve the platform's service life and load-bearing capacity. In this embodiment, the gas cutting loading platform 14 is equipped with six second rollers 16, which are spaced apart along the processing direction. The second rollers 16 are driven by an electric drive device connected to the bottom of the gas cutting loading platform 14. The electric drive device can adjust the rotation speed and direction of the second rollers 16 according to a preset program or real-time control signal. When the material 18 is placed in the second bearing area, the second rollers 16 begin to rotate under the control of the electric drive device, smoothly moving the material 18 along the length of the second bearing area to the processing position of the gas cutting robot.

[0056] Optionally, the installation of the second roller 16 must ensure alignment with the first roller 5 to enable smooth movement of the workpiece on the production line. Simultaneously, the surface treatment of the second roller 16 must be designed to prevent workpiece slippage or damage, ensuring the safety and integrity of the workpiece during movement.

[0057] Furthermore, the gas cutting loading platform 14 includes a rib cutting mold 15, which is positioned on the side of the gas cutting loading platform 14 closest to the gas cutting robot. When the second roller 16 drives the material 18 to abut against the rib cutting mold 15, the material 18 is in the rib processing position. Through the customized rib cutting mold 15, efficient cutting of ribs of different specifications can be achieved, meeting the diverse design needs of I-beam shed beams.

[0058] The rib cutting mold 15 is made of high-strength steel and is designed as a fixed straight-mouth mold. The width of the straight mouth matches the width of the ribs of the I-beam beam, ensuring that the material remains stably in the preset processing position during the cutting process. Three positioning buckles are designed on both sides of the straight mouth of the mold to further fix the position of the material 18 when it comes into contact with the mold, preventing lateral or longitudinal displacement of the material 18 during cutting, thus ensuring cutting accuracy and consistency. The angle between the straight mouth of the mold and the horizontal direction is 16°. This design ensures that the I-beam beam can stably enter the mold at a preset angle when it moves to the mold via the second roller 16, facilitating subsequent cutting operations.

[0059] Specifically, the gas cutting loading platform 14 includes a beam claw cutting mold 17, which is detachably connected to the rib plate cutting mold 15. When the second roller 16 drives the material 18 to abut against the beam claw cutting mold 17, the material 18 is in the beam claw processing position. This detachable design allows the production line to quickly adapt to the production needs of different products, improving equipment utilization and production flexibility.

[0060] The beam-claw cutting mold 17 is made of high-strength steel and designed as a slanted mold with a 70° slant angle to ensure that the I-beam beam is stably positioned on the mold. Buckles on both sides of the slant are used to secure the workpiece and prevent displacement during cutting. Driving the second roller 16 ensures that the material 18 is positioned in the beam-claw processing position. At this time, the gas cutting robot performs precise beam-claw cutting operations using the material 18 positioned by the mold according to the preset cutting program. After cutting, the second roller 16 restarts, smoothly moving the cut material 18 (such as the beam claw) out of the processing position for subsequent processing. This combination of automated cutting and movement not only improves cutting accuracy and efficiency but also optimizes the management of the material 18 on the production line, reduces manual intervention, and lowers production costs.

[0061] It should be further explained that a fixing buckle is installed at the top of the gas cutting loading platform 14. Its functions are twofold: first, to ensure the front and rear positions are on the same horizontal line to prevent cutting errors; and second, to prevent material 18 from falling off if there is a gap after the beam claws and stiffeners have been cut in the previous stage. A set screw is installed on the fixing buckle; the set screw applies a certain force to lift the material 18, ensuring that the unprocessed material 18 is on a horizontal line.

[0062] In this embodiment, the entire gas cutting process consists of a TR6 / 1400 gas cutting robot, an LGK-200HD plasma gas cutting machine, an SRC2.7S electrical control box, and a Spad-k8 teach pendant, all of which are mounted on the gas cutting loading platform 14. Communication between the robot and the plasma gas cutting machine is achieved through digital I / O and analog I / O connections to the machine's input / output terminals. The teach pendant's gas cutting configuration interface then associates gas delivery, electrode, and other cutting signals, and the control circuit generates a plasma flame. The robot automatically adjusts the cutting nozzle's posture and cutting speed based on the signal transmission information to perform precise gas cutting operations.

[0063] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0064] 1. By using robotic automatic gas cutting and welding technology, the processing of I-beam shed beam claws and stiffening plates has been fully automated, which has greatly improved the speed of cutting and welding, reduced reliance on manual labor, and made the production process more efficient. It can significantly increase the annual output of I-beam shed beams to meet the high production needs of coal mines.

[0065] 2. The first and second positioning devices ensure the precise alignment of the parts to be welded, reducing manual intervention. The rotation of the first roller 5 enables the automatic feeding and positioning of the beam 3 and the claw 4 to be welded, thereby allowing them to move relative to the welding platform 1 or the base frame 2 during the welding process, achieving the purpose of automated welding. This design significantly improves welding efficiency and accuracy.

[0066] 3. Replacing manual labor with robots in high-intensity welding and gas cutting operations reduces health risks to workers, such as minimizing exposure to welding fumes, arc light, and high temperatures. Simultaneously, automated production reduces material waste and labor costs, improving both economic efficiency and safety.

[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
