Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a building material conveying device. Background Technology

[0002] In modern construction, the efficient and safe transport of materials is crucial for ensuring project progress and quality. I-beams, as important load-bearing components in building structures, are often used as temporary or permanent material transport tracks.

[0003] Currently, material transport on I-beams mainly employs the following methods: Manual handling: Workers walk along the steel beam or use simple lifting devices to move materials. This method is labor-intensive, inefficient, and poses a safety hazard of falls from heights. Electric hoists or monorail cranes: Electric hoists or monorail cranes are installed on the I-beams and moved along the beams to lift materials. While these devices achieve mechanization, they typically only move in a straight line, making it difficult to achieve flexible transport in multiple directions or at multiple workstations, and installation and disassembly are relatively cumbersome. Simple pulleys: Pulleys with rollers slide on the I-beams, relying on manual labor or external traction for movement. This device has poor stability, is prone to derailment or jamming, and lacks effective braking and positioning functions.

[0004] Existing equipment generally suffers from the following shortcomings: Single conveying direction: It can only move in a straight line along the I-beam, unable to adjust the conveying angle or perform circular conveying according to construction needs. Poor stability: The fit with the I-beam is not tight enough, making it prone to swaying or derailment during movement, affecting conveying safety. Insufficient adaptability: It lacks an adaptive clamping mechanism for I-beams of different specifications, requiring manual adjustment. Low automation: The lifting, conveying, and positioning of materials largely rely on manual operation, resulting in low efficiency. Lack of modular design: The connection between the conveying device and the steel beam is complex, making rapid installation and disassembly difficult.

[0005] Therefore, there is an urgent need for an automated material conveying device that can move stably along I-beams, convey materials in multiple directions, is highly adaptable, and is easy to install and disassemble. Summary of the Invention

[0006] The present invention provides a building material conveying device that solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A building material conveying device includes an I-beam with several fixed missing-ring mechanisms on it. Each fixed missing-ring mechanism has a rotating arc plate mechanism. The rotating arc plate mechanism has several mounting sleeves evenly distributed around its circumference.

[0010] As a preferred embodiment of the present invention, the rotating arc plate mechanism includes two motor mounts fixed on the missing ring. The two motor mounts are symmetrically arranged on the missing ring. The motor mounts are fixedly connected to a first motor. The output shaft of the first motor is fixedly connected to a first gear. The first gear meshes with an arc-shaped rack. The inner side of the arc-shaped rack is fixedly connected to a rotating arc plate. The rotating arc plate is located in a movable arc groove. The rotating arc plate and the missing ring are slidably connected. The mounting sleeve passes through the rotating arc plate.

[0011] As a preferred embodiment of the present invention, the reset gear mechanism includes a reset mechanism disposed on a fixed plate, the reset mechanism being connected to a second gear, the reset mechanism including a fixed shaft fixed to the fixed plate, a torsion spring fixedly connected to the outer side of the fixed shaft, a reset sleeve fixedly connected to the end of the torsion spring away from the fixed shaft, the reset sleeve and the fixed plate being rotatably connected, and the reset sleeve and the second gear being fixedly connected.

[0012] As a preferred embodiment of the present invention, the deflecting chuck mechanism includes a slider groove on a fixed plate, an elastic element fixedly connected to the fixed plate within the slider groove, a slider fixedly connected to the end of the elastic element, the slider being located within the slider groove, the slider and the fixed plate being slidably connected, the slider being rotatably connected to a first rotating shaft, the first rotating shaft being coaxially fixedly connected to a third gear, the third gear meshing with a second gear, the first rotating shaft being fixedly connected to a deflecting rod, the upper end of the deflecting rod being rotatably connected to a first chuck, the lower end of the deflecting rod being provided with a second motor, the output shaft of the second motor being fixedly connected to a second chuck, the second chuck and the deflecting rod being rotatably connected, the first chuck and the second chuck contacting an I-beam, and a plurality of ball bearings being provided on the side of the first chuck and the side of the second chuck near the I-beam.

[0013] As a preferred embodiment of the present invention, the positioning frame mechanism includes a positioning sleeve disposed outside the mounting sleeve, the positioning sleeve being threadedly connected to a locking bolt, the end of the locking bolt being in contact with the mounting sleeve, and the positioning sleeve being fixedly connected to the positioning frame.

[0014] As a preferred embodiment of the present invention, the lifting and conveying mechanism includes a conveying slide, a positioning frame passing through the conveying slide, the positioning frame and the conveying slide being slidably connected, a linear motor being fixedly connected between the positioning frame and the conveying slide, a first conveying shaft being rotatably connected to the upper part of the conveying slide, a second rotating shaft being rotatably connected to the lower part of the conveying slide, two first synchronous pulleys being coaxially and fixedly connected to the first conveying shaft, two second synchronous pulleys being coaxially and fixedly connected to the second rotating shaft, a synchronous belt being driven by the first and second synchronous pulleys, and a plurality of storage shells being fixedly connected to the synchronous belt.

[0015] As a preferred embodiment of the present invention, the drive gear mechanism includes a first bevel gear coaxially and fixedly connected to the first conveying shaft, the first bevel gear meshing with a second bevel gear, the second bevel gear coaxially and fixedly connected to the drive shaft, the drive shaft and the conveying carriage being rotatably connected, and a fourth gear fixedly connected to the end of the drive shaft away from the second bevel gear. When the fourth gear rises to its highest point, it meshes with a rack. The rack is located on both sides of the fourth gear. The length of the rack and the relative position of the rack and the fourth gear are selected according to the actual situation. When the second chuck moves and drives the missing ring to move along the I-beam, the fourth gear meshes with the rack and will then rotate.

[0016] The present invention has the following advantages:

[0017] 1. Adaptive clamping and stable movement: The deflecting roller mechanism drives the slider to slide through an elastic element, ensuring that the first and second rollers remain in close contact with the flanges and web of the I-beam. The ball bearings on the sides of the first and second rollers convert sliding friction into rolling friction, ensuring clamping stability and reducing movement resistance. The reset gear mechanism, through a torsion spring, maintains an inward clamping force on both sides of the deflecting roller mechanism, achieving adaptive adjustment to accommodate I-beams of different specifications.

[0018] 2. Multi-directional conveying and flexible repositioning: The rotating arc plate mechanism is driven by a first motor to drive an arc-shaped rack, which in turn drives the rotating arc plate to slide along the moving arc groove with a missing ring, realizing the overall repositioning of the conveying assembly. The conveying assembly can switch in multiple directions on the I-beam to meet the multi-directional material conveying needs in complex construction scenarios.

[0019] 3. Precise drive and reliable positioning: The lifting and conveying mechanism uses a linear motor to drive the conveyor carriage to rise and fall, causing the fourth gear in the drive gear mechanism to mesh with the rack at the bottom of the I-beam. The rack's length and installation position can be selected according to actual needs, enabling the conveying assembly to start, stop, and be precisely positioned at any location.

[0020] 4. Modular design, easy installation: The fixed missing ring mechanism is connected to the I-beam via the missing ring and fixed plate; the rotating arc plate mechanism is installed on the missing ring; and the conveying component is quickly installed on the mounting sleeve via the positioning sleeve and locking bolts of the positioning frame mechanism. Each module is independently designed, facilitating rapid on-site assembly and disassembly.

[0021] 5. Large conveying capacity and continuous operation: The lifting conveyor mechanism uses a synchronous belt to drive multiple storage tanks to move in a circular motion, enabling continuous conveying and storage of materials. The storage tanks can be designed according to the shape of the materials and are suitable for conveying various building materials such as pipes, plates, and small components.

[0022] 6. High safety and anti-derailment: The first and second chucks of the deflection chuck mechanism clamp the flanges of the I-beam from the top and bottom, forming a three-point clamping, which effectively prevents the device from derailing or overturning during the conveying process and ensures the safety of high-altitude operations.

[0023] 7. High degree of automation: By controlling the coordinated work of various motors and linear motors, automatic lifting, conveying, changing direction and positioning of materials can be realized, reducing manual intervention and improving construction efficiency.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0034] For examples, please refer to Figures 1-6 A building material conveying device includes an I-beam 1, on which several fixed missing-ring mechanisms 2 are provided. Each fixed missing-ring mechanism 2 is equipped with a rotating arc plate mechanism 3. Several mounting sleeves 4 are evenly arranged around the circumference of the rotating arc plate mechanism 3. Two symmetrically arranged drive components are provided on the inner side of the rotating arc plate mechanism 3. Each drive component includes a reset gear mechanism 5 and two deflecting roller mechanisms 6, with the two deflecting roller mechanisms 6 respectively located on both sides of the reset gear mechanism 5. A conveying component is provided on each mounting sleeve 4. The conveying component includes a positioning frame mechanism 7 and a lifting mechanism. The conveying mechanism 8 and the drive gear mechanism 9 are located on the outside of the mounting sleeve 4. The lifting and conveying mechanism 8 is located on the positioning frame mechanism 7, and the drive gear mechanism 9 is located on the lifting and conveying mechanism 8. Several racks 10 are provided at the bottom of the I-beam 1. The fixed missing ring mechanism 2 is used to install the rotating arc plate mechanism 3. The reset gear mechanism 5 is used to lock and position the two deflection chuck mechanisms 6. The positioning frame mechanism 7 is used to install on the mounting sleeve 4. The lifting and conveying mechanism 8 is used to control the meshing of the drive gear mechanism 9 and the racks 10. The lifting and conveying mechanism 8 is used to convey building materials.

[0035] The fixed missing ring mechanism 2 includes a missing ring 201, with two symmetrically arranged fixed plates 202 fixedly connected to the inner side of the missing ring 201. The missing ring 201 has a movable arc groove 203 and a driving notch 204. The rotating arc plate mechanism 3 includes two motor mounts 301 fixed to the missing ring 201, symmetrically arranged on the missing ring 201. A first motor 302 is fixedly connected to the motor mounts 301, and the output shaft of the first motor 302 is fixedly connected to a first gear 303. The first gear 303 meshes with an arc-shaped rack 304. A rotating arc plate 305 is fixedly connected to the inner side of the arc-shaped rack 304. The rotating arc plate 305 is located within the movable arc groove 203, and is slidably connected to the missing ring 201. A mounting sleeve 4 passes through the rotating arc plate 305.

[0036] Specifically, when the first motor 302 starts, it drives the arc rack 304 to move through the first gear 303, which in turn drives the rotating arc plate 305 to slide along the moving arc groove 203, thereby realizing the displacement of the mounting sleeve 4 and the conveying assembly, so that the conveying assembly can convey materials at different lateral positions of the I-beam 1.

[0037] The reset gear mechanism 5 includes a reset mechanism 501 disposed on the fixed plate 202. The reset mechanism 501 is connected to the second gear 502. The reset mechanism 501 includes a fixed shaft 5011 fixed on the fixed plate 202. A torsion spring 5012 is fixedly connected to the outside of the fixed shaft 5011. A reset sleeve 5013 is fixedly connected to the end of the torsion spring 5012 away from the fixed shaft 5011. The reset sleeve 5013 and the fixed plate 202 are rotatably connected. The reset sleeve 5013 and the second gear 502 are fixedly connected. The deflecting chuck mechanism 6 includes a slider groove 601 on a fixed plate 202. An elastic element 602 is fixedly connected to the fixed plate 202 within the slider groove 601. A slider 603 is fixedly connected to the end of the elastic element 602. The slider 603 is located within the slider groove 601 and is slidably connected to the fixed plate 202. The slider 603 is rotatably connected to a first rotating shaft 604. The first rotating shaft 604 is coaxially fixedly connected to a third gear 605. The third gear 605 meshes with a second gear 502. The first rotating shaft 604 is fixedly connected to the deflection rod 606. The upper end of the deflection rod 606 is rotatably connected to the first chuck 607. The lower end of the deflection rod 606 is provided with a second motor 608. The output shaft of the second motor 608 is fixedly connected to the second chuck 609. The second chuck 609 and the deflection rod 606 are rotatably connected. The first chuck 607 and the second chuck 609 are in contact with the I-beam 1. Several balls are provided on the side of the first chuck 607 and the side of the second chuck 609 near the I-beam 1.

[0038] Specifically, the torsion spring 5012 provides a continuous torsional force, causing the second gear 502 to tend to rotate back to its initial position, thus ensuring that the deflection roller mechanisms 6 on both sides always generate an inward clamping force. The first roller 607 and the second roller 609 contact the I-beam 1, and their sides near the I-beam 1 are provided with several balls to reduce friction and convert sliding friction into rolling friction. Under the thrust of the elastic element 602, the slider 603 moves towards the second gear 502, thereby achieving stable meshing of the third gear 605 and the second gear 502. When the meshing of the third gear 605 and the second gear 502 is disengaged, the included angle of the two deflection rods 606 can be controlled, thus adapting to the movement and conveying of I-beams with different structures. The second motor 608 drives the second roller 609 to rotate, providing driving force for the device to move along the I-beam 1.

[0039] The positioning frame mechanism 7 includes a positioning sleeve 701 located outside the mounting sleeve 4. The positioning sleeve 701 is threadedly connected to a locking bolt 702, the end of which contacts the mounting sleeve 4. The positioning sleeve 701 is fixedly connected to a positioning frame 703. The lifting and conveying mechanism 8 includes a conveying slide 801. The positioning frame 703 passes through the conveying slide 801 and is slidably connected to it. A linear motor 802 is fixedly connected between the positioning frame 703 and the conveying slide 801. The upper part of the conveying slide 801 is rotatably connected to a first conveying shaft 803, and the lower part is rotatably connected to a second rotating shaft 804. The first conveying shaft 803 is coaxially fixedly connected to two first synchronous pulleys 805, and the second rotating shaft 804 is coaxially fixedly connected to two second synchronous pulleys 806. The first synchronous pulleys 805 and the second synchronous pulleys 806 are driven by a synchronous belt 807, which is fixedly connected to several storage shells 808. The drive gear mechanism 9 includes a first bevel gear 901 coaxially and fixedly connected to the first conveying shaft 803. The first bevel gear 901 meshes with a second bevel gear 902. The second bevel gear 902 is coaxially and fixedly connected to the drive shaft 903. The drive shaft 903 is rotatably connected to the conveying carriage 801. A fourth gear 904 is fixedly connected to the end of the drive shaft 903 away from the second bevel gear 902. When the fourth gear 904 rises to its highest point, it meshes with the rack 10. The rack 10 is located on both sides of the fourth gear 904. The length of the rack 10 and the relative position of the rack 10 and the fourth gear 904 are selected according to the actual situation. When the second chuck 609 moves and drives the missing ring 201 to move along the I-beam 1, the fourth gear 904 meshes with the rack 10 and will rotate.

[0040] Specifically, the end of the locking bolt 702 contacts the mounting sleeve 4, and tightening it fixes the position of the positioning sleeve 701. The positioning sleeve 701 is fixedly connected to the positioning frame 703, providing support for the lifting and conveying mechanism. Several storage shells 808 are fixedly connected to the synchronous belt 807 for holding building materials. When the first conveying shaft 803 rotates, the storage shells 808 are driven to move cyclically through the synchronous belt 807, realizing continuous material conveying. When the linear motor 802 drives the conveyor slide 801 to rise, the fourth gear 904 rises accordingly; when the fourth gear 904 rises to the highest point, it meshes with the rack 10 at the bottom of the I-beam 1.

[0041] Specifically, when the second roller 609 moves, driving the missing ring 201 to move along the I-beam 1, the fourth gear 904 and the rack 10 are engaged. At this time, the fourth gear 904 rotates during the movement. This design utilizes the high-precision characteristics of gear and rack meshing to ensure the accuracy and stability of the device's movement, avoiding the slippage problem of traditional drive wheels. The rack 10 can be selected in length and installation position according to actual needs, and is respectively set on both sides of the fourth gear 904 to control the forward and reverse rotation of the fourth gear 904, thereby controlling the forward or reverse rotation of the synchronous belt 807.

[0042] The workflow of this invention is as follows:

[0043] Device Installation: The missing ring 201 of the fixed missing ring mechanism 2 is fitted onto the I-beam 1, so that the fixing plate 202 is located on both sides of the web of the I-beam 1. The deflecting roller mechanism 6 automatically clamps the flange of the I-beam 1 under the action of the elastic element 602 and the torsion spring 5012. The first roller 607 and the second roller 609 are in close contact with the surface of the I-beam 1, and the ball bearings reduce friction.

[0044] Installation and Direction Adjustment of Conveying Components: Place the positioning sleeve 701 of the positioning frame mechanism 7 onto the mounting sleeve 4 and tighten the locking bolt 702 to secure it. According to the required conveying direction, start the first motor 302, which drives the arc rack 304 through the first gear 303, causing the rotating arc plate 305 to slide along the moving arc groove 203, thereby adjusting the conveying component to the required direction.

[0045] Material loading: The building materials are placed into the storage shell 808. The storage shell 808 can be designed according to the shape of the materials and is suitable for various materials such as pipes and plates.

[0046] Conveying Movement: The linear motor 802 is started, driving the conveyor carriage 801 to rise, causing the fourth gear 904 to mesh with the rack 10 at the bottom of the I-beam 1. The second motor 608 is started, driving the second chuck 609 to rotate, moving the entire device along the I-beam 1. During movement, because the fourth gear 904 remains meshed with the rack 10, the fourth gear 904 rotates. This rotation drives the drive shaft 903 to rotate, which in turn drives the second bevel gear 902, which in turn drives the first bevel gear 901 to rotate. The rotation of the first bevel gear 901 drives the first conveyor shaft 803 to rotate, which in turn drives the storage tank 808 to move cyclically via the synchronous belt 807, continuously conveying the material to the target position.

[0047] Material unloading: After reaching the target position, since there is a rack 10 on the other side of the fourth gear 904, the fourth gear 904 can rotate in the opposite direction, thereby driving the synchronous belt 807 to rotate in the opposite direction, and transporting the material in the storage shell 808 to the unloading point to complete the unloading.

[0048] Through the above design, this invention achieves stable, flexible, and efficient material transport on I-beams, significantly improving the level of automation in material handling at construction sites.

[0049] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
