[0032] Example

[0033] The present invention provides a tunnel construction device, which may be a crane, an excavator, or a loader. The tunnel construction device includes a boom and a construction platform device, wherein the boom and the operating platform are connected and cooperate with each other to complete various construction tasks.

[0034] Specifically, the boom, as a flexible and adjustable mechanical structure, is commonly used for various operations in tunnel construction, while the construction platform device, as a fixed or mobile working platform, provides a safe and stable working environment for construction workers.

[0035] It should be emphasized that while ensuring that tunnel construction equipment pursues versatility and high integration, the above-mentioned construction platform device can also ensure construction safety, that is, it can achieve the beneficial effect of balancing safety and functionality.

[0036] Specifically, the construction platform device includes an operating platform and a foldable guardrail 10, with the operating platform connected to the foldable guardrail 10. The operating platform is used to support construction workers' safe operations. The foldable guardrail 10 allows for adjustment according to construction needs to accommodate different work scenarios, effectively eliminating interference with other construction components and ensuring the safety of operators.

[0037] The specific structures of the various components of the foldable guardrail 10 provided in this embodiment and the corresponding relationships between them will be described in detail below. Figure 1 This is a schematic diagram of the foldable guardrail 10 provided in an embodiment of the present invention in an unfolded state. Figure 2 This is a schematic diagram of the foldable guardrail 10 provided in an embodiment of the present invention in a folded state.

[0038] See also Figure 1 and Figure 2 The present invention provides a foldable guardrail 10, which includes a guardrail base 100 and a guardrail assembly 300. The guardrail base 100 is used to connect to an operating platform, and the guardrail assembly 300 is rotatably connected to the guardrail base 100 to facilitate dynamic adjustment of the foldable guardrail 10 relative to the operating platform.

[0039] Specifically, if Figure 3 and Figure 4 As shown, the guardrail base 100 is provided with a first limiting groove 111 and a second limiting groove 113. Furthermore, when the guardrail assembly 300 is in the unfolded state, the guardrail assembly 300 engages with the first limiting groove 111; when the guardrail assembly 300 is in the folded state, the guardrail assembly 300 engages with the second limiting groove 113.

[0040] Applied to actual working scenarios, that is, when the parts in the equipment need to rotate or swing, such as Figure 1 and Figure 3 As shown, the guardrail assembly 300 cooperates with the first limiting groove 111 and is in an unfolded state, thereby providing the operator with a larger movement space and avoiding the operational inconvenience caused by the limitation of the foldable guardrail 10.

[0041] When personnel are working at heights or in dangerous areas, Figure 2 and Figure 4 As shown, the guardrail assembly 300 cooperates with the second limiting groove 113 and is in a folded state, thereby effectively preventing accidental falls, significantly reducing the risk of work-related accidents, and protecting the personal safety of construction workers.

[0042] Based on the dynamic adjustment of the above-mentioned protective components, the foldable guardrail 10 can flexibly switch between multiple operating modes, adapt to different work scenarios, effectively solve the interference problem with other construction components, and ensure the safety protection of operators.

[0043] Please refer again Figure 3 and Figure 4 As an optional embodiment, the foldable guardrail 10 further includes a pin 510 and a cotter pin 530. The guardrail assembly 300 is rotatably connected to the guardrail base 100 via the pin 510; the pin 510 has a mounting hole, and the cotter pin 530 engages with the mounting hole.

[0044] It should be noted that the pin 510 is used to connect the guardrail assembly 300 and the guardrail base 100 so that the two can be accurately docked, and can serve as a rotation axis to allow relative rotational movement between the two connected components, thereby realizing various functions.

[0045] The cotter pin 530 is typically used to lock or unlock the pin shaft 510, preventing the pin shaft 510 or its mating parts from moving or loosening during operation. Specifically, the cotter pin 530 is inserted into the mounting hole and has both ends bent outward to form a simple but effective locking mechanism, preventing the pin shaft 510 from moving along its axis or falling off.

[0046] To facilitate rapid stabilization of the guardrail assembly 300 after dynamic adjustment to the working position, the guardrail assembly 300 includes a connecting plate 310, a protrusion 330, and a guardrail rod 350. The connecting plate 310 is rotatably connected to the guardrail base 100 and to the guardrail rod 350, and engages with the first retaining groove 111. The protrusion 330 is connected to the connecting plate 310 and engages with the second retaining groove 113.

[0047] It can be understood that when the connecting plate 310 and the first limiting groove 111 are in cooperation, the guardrail rod 350 rotates along with the connecting plate 310 and flips over to be in an unfolded state to avoid construction components; when the protrusion 330 and the second limiting groove 113 are in cooperation, the connecting plate 310 also flips over with the guardrail rod 350 accordingly and is in a folded state to protect construction personnel.

[0048] Moreover, based on the arrangement of the connection plate 310 and the first limiting groove 111, and the protrusion 330 and the second limiting groove 113, rapid clamping and fixing between the corresponding matching parts can be achieved, thereby simplifying the assembly process, improving the dynamic adjustment efficiency, and thus improving the construction efficiency.

[0049] In some embodiments, the guardrail base 100 is configured as a standpipe structure 110. Standpipe structure 110 is provided with a first retaining groove 111 and a second retaining groove 113 disposed opposite each other along a first direction 910. This facilitates rapid state switching of the guardrail assembly 300, reducing alignment and adjustment time. Accordingly, one side of the connecting plate 310 engages with the first retaining groove 111, while the other, opposing side is connected to the protrusion 330.

[0050] It should also be noted that the notches of the first limiting groove 111 and the second limiting groove 113 can both be provided with chamfered guides to facilitate the smooth entry of the corresponding connecting plate 310 and the protrusion 330. Furthermore, it should also be noted that the first limiting groove 111 can be configured to transitionally fit with the connecting plate 310, and the second limiting groove 113 can also be configured to transitionally fit with the protrusion 330, to ensure that the above-mentioned mating parts will not easily slip off when clamped and fixed.

[0051] Considering the hollow structure of riser structure 110, drain grooves 115 are provided at the bottom of riser structure 110. This facilitates the rapid drainage of accumulated water and prevents it from stagnating for extended periods within riser structure 110. This helps reduce corrosion caused by water stains and moisture on riser structure 110, thereby extending the service life of riser structure 110.

[0052] To enhance safety, the projection of the connecting plate 310 on a predetermined plane overlaps the projection of the second retaining groove 113 on a predetermined plane perpendicular to the first direction 910. It is understood that when the protrusion 330 and the second retaining groove 113 engage, the riser structure 110 is retained by the connecting plate 310, maintaining a vertical orientation of the connecting plate 310 and the guardrail 350. Furthermore, based on the positional relationship between the connecting plate 310 and the protrusion 330, the connecting plate 310 rotates 90 degrees under the action of an external force, engaging the first retaining groove 111, and the guardrail 350 is now positioned horizontally.

[0053] This means that, in the present application, the guardrail assembly 300 can be switched between the deployed and folded states by rotating it forward or backward 90 degrees. Specifically, when the guardrail assembly 300 is in the deployed state, the guardrail rod 350 is placed horizontally to avoid obstructing the rotation or swinging of construction components, thereby improving construction efficiency. When the guardrail assembly 300 is in the folded state, the guardrail rod 350 is placed vertically to effectively protect workers and improve safety.

[0054] Please refer again Figure 1 and Figure 2In some embodiments, there are two riser structures 110, which are spaced apart along a second direction 930 perpendicular to the first direction 910. Accordingly, the connecting plates 310 and the protrusions 330 each correspond one-to-one with the riser structures 110. It should be noted that the one-to-one correspondence here refers to a one-to-one correspondence in both position and quantity.

[0055] In addition, the two connecting plates 310 are respectively connected to the opposite ends of the guardrail bar 350 along the second direction 930, thereby ensuring the balance and stability of the guardrail bar 350 during the flipping process when flipping from the unfolded state to the folded state, or from the folded state to the unfolded state.

[0056] In addition to the above, the foldable guardrail 10 also includes a baffle 700 connecting the two riser structures 110. As will be appreciated, the baffle 700 effectively prevents tools, building materials, or other small items from falling from the platform during construction, reducing the likelihood of accidents. Furthermore, the baffle 700 prevents workers from accidentally extending their feet over the edge of the platform, thereby improving the safety of construction workers.

[0057] Furthermore, the baffle 700 is located on the side of the riser structure 110 where the second retaining groove 113 is formed, and the projection of the baffle 700 on the predetermined plane overlaps the projection of the protrusion 330 on the predetermined plane. This means that when the protrusion 330 engages with the second retaining groove 113, the baffle 700's restraining action on the protrusion 330 enables the connecting plate 310 and the guardrail 350 to be positioned vertically. Similarly, when the connecting plate 310 is rotated 90 degrees by an external force, i.e., it engages with the first retaining groove 111, the guardrail 350 is now positioned horizontally. This will not be further described here.

[0058] Taking this embodiment as an example, the present application provides a foldable guardrail 10, whose working principle and workflow are as follows: when the components in the equipment need to be rotated or swung, the connecting plate 310 cooperates with the first limiting groove 111, and the guardrail rod 350 is placed horizontally, thereby providing the operator with a larger space for movement and avoiding the operational inconvenience caused by the limitation of the foldable guardrail 10; when personnel are performing construction at high places or in dangerous areas, the protrusion 330 cooperates with the second limiting groove 113, and the guardrail rod 350 is placed vertically, which can effectively prevent accidental falls, significantly reduce the risk of work-related accidents, and protect the personal safety of construction workers.

[0059] In summary, the present invention provides a foldable guardrail 10, a construction platform device, and tunnel construction equipment, which includes a guardrail base 100 and a guardrail assembly 300. The guardrail base 100 is connected to the operating platform, and the guardrail assembly 300 is rotatably connected to the guardrail base 100 to facilitate dynamic adjustment of the foldable guardrail 10 relative to the operating platform.

[0060] Based on the above, the guardrail base 100 is provided with a first limiting slot 111 and a second limiting slot 113. Furthermore, when the guardrail assembly 300 is in the deployed state, it engages with the first limiting slot 111; when the guardrail assembly 300 is in the folded state, it engages with the second limiting slot 113. Due to the dynamic adjustment of the guardrail assembly described above, the foldable guardrail 10 can flexibly switch between multiple operating modes to adapt to different work scenarios, effectively eliminating interference with other construction components and ensuring the safety of operators.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
