Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a conveying device for arc-shaped I-beams. Background Art

[0002] The steel arch is a rigid skeleton made of I-beams or rails. It has the characteristics of high rigidity and large bearing capacity. It can be used as a temporary support and withstand large surrounding rock pressure alone. It can also be set in concrete as part of the permanent lining. It is often used together with anchor rods, shotcrete, etc. in soft and broken or soil tunnels.

[0003] In the existing conventional process for manufacturing steel arch frames, I-beams need to be manually transported and placed at welding stations after cutting, which leads to low production efficiency and safety risks, affecting production efficiency and posing safety hazards. In the "Automated Production Line for Steel Arch Frames" disclosed in publication number CN109128853B, a raw material bracket transports the steel arch frame to an automatic welding unit for welding. After welding is completed, a welding ejection device places the welded workpiece on a conveyor chain and transports it to the next station. However, after cutting the I-beam, the steel shearing equipment needs to align the I-beam through multiple balanced ejection guide devices so that the cut I-beam can be docked with the automatic welding unit. This increases the complexity of the operation and requires many preparatory operations before welding, affecting the efficiency and consistency of the entire production line. Utility Model Content

DETAILED DESCRIPTION

[0033] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0034] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0035] like Figures 1 to 3 As shown, the arch bender 6 bends the unbent I-beam into shape, the sawing machine 7 cuts the bent and formed curved I-beam 5, and the conveyor is used to transport the cut curved I-beam 5 to the welding station of the conveyor for welding. The conveyor allows arch bending, cutting, and welding to be performed simultaneously, eliminating the need to clear space after cutting before welding, thereby improving the production efficiency of the curved I-beam 5.

[0036] The aforementioned conveying device for curved I-beams comprises a mechanical support frame 1 and an output guide assembly 2. The mechanical support frame 1 serves as the basic structure of the entire device, providing support and fixation. The output guide assembly 2 is responsible for transporting the cut curved I-beams 5 from the receiving position to the subsequent welding point.

[0037] A receiving device 3 is mounted on one side of the mechanical support frame 1. This device consists of a mechanical roller 31 and a lifting cylinder 32. Several mechanical rollers 31 are mounted on the mechanical support frame 1 via the lifting cylinder 32 and arranged along the length of the mechanical support frame 1, forming a continuous support and transmission chain. This ensures smooth and continuous movement of the curved I-beam during transport, reducing resistance and friction during transport and improving efficiency.

[0038] The mechanical roller 31 transfers the cut arc-shaped I-beam 5 from the sawing machine 7 to the position of the receiving device 3 through the mechanical roller 31. When the arc-shaped I-beam 5 moves as a whole to the receiving device 3, the motor drives the lifting cylinder 32 to lower the height of the mechanical roller 31, so that the arc-shaped I-beam 5 is placed above the output guide rail assembly 2. The motor drives the guide rail 22 in the output guide rail assembly 2 to move the arc-shaped I-beam 5 toward the end of the guide rail 22. When the arc-shaped I-beam 5 is transported to the area outside the receiving device 3, the two sides of the arc-shaped I-beam 5 are suspended in the air, which is convenient for welding operations.

[0039] The output guide rail assembly 2 is mounted on the mechanical support frame 1, aligned with the orientation of the mechanical rollers 31. Because the output guide rail assembly 2 and the mechanical rollers 31 are aligned, the curved I-beam 5 maintains a smooth transmission path when being transferred from the receiving device 3 to the output guide rail assembly 2. This reduces resistance and jolting during transmission, ensuring smooth transfer of the curved I-beam 5. Furthermore, mounting the output guide rail assembly 2 directly on the mechanical support frame 1 avoids the need for additional space. This compact design makes the entire conveyor more compact and efficient, improving space utilization.

[0040] The mechanical support frame 1 is further divided into a roller support frame 11 and a guide rail support frame 12. The roller support frame 11 is used to support the receiving device 3 and the output guide rail assembly 2, ensuring their stability and reliability. The guide rail support frame 12 is specifically used to support the output guide rail assembly 2, allowing it to smoothly transport the curved I-beam 5.

[0041] The output guide rail assembly 2 consists of a support column 21 and a guide rail 22. The guide rail 22 is fixed to the mechanical support frame 1 through the support column 21 and is aligned with the arrangement direction of the mechanical roller 31, thereby ensuring that the curved I-beam 5 can be smoothly transferred from the receiving device 3 to the welding position.

[0042] Furthermore, in order to facilitate the fixing of the lifting cylinder 32 and the support column 21, the mechanical support frame 1 is further provided with fixing grooves 10. These fixing grooves 10 make the assembly process more simple and efficient.

[0043] The conveyor also includes a side positioning assembly 4, which supports one end of the curved I-beam to prevent it from shifting during transport. This assembly consists of a side support frame 41, a positioning mechanical roller 42, and a positioning lift cylinder 43. The side support frame 41 is positioned on one side of the roller support frame 11. The positioning mechanical roller 42 is assembled to the side support frame 41 via a positioning lift cylinder 43 and positioned along the arrangement of the mechanical rollers 31. The side positioning assembly 4 rises and falls in sync with the receiving device 3, improving the stability of the conveyor.

[0044] A buffer device is also provided at the end of the output guide rail assembly 2. The buffer device can reduce the impact force of the curved I-beam 5 when it is transmitted to the end, protecting the curved I-beam 5 and the conveying device from damage.

[0045] In order to improve the anti-skid performance of the mechanical roller 31, anti-skid grooves are provided on its surface, which can increase the friction between the mechanical roller 31 and the curved I-beam 5 and prevent the curved I-beam 5 from sliding during the transmission process.

[0046] Furthermore, to improve the stability and reliability of the conveyor, a rubber shock-absorbing structure is installed at the lower end of the mechanical support frame 1. The rubber shock-absorbing structure can effectively absorb the vibration and impact generated during the conveying process, protecting the stability of the conveyor and the surrounding environment, and extending the service life of the device.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
