Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation, in particular to a turnable manned platform for special tunnel equipment. Background Technique

[0002] Special tunnel equipment is special equipment for tunnel excavation. Common special tunnel equipment includes rock drilling jumbo, charging jumbo, wet spraying jumbo, etc. Due to the narrow space in the tunnel, strict requirements are imposed on the size of the special equipment. During the actual tunnel excavation process, operators often need to perform relevant operations on the platform of the special equipment.

[0003] The existing manned platforms of special tunnel equipment generally include fixed type and lifting type. Among them, if the fixed platform is designed with too large a size, it will cause certain difficulties for the special equipment to enter and exit the tunnel. If the design size is small, the operating space for the operator is too small, resulting in inconvenient operation. The lifting platform usually adopts a scissor type and is powered by an oil cylinder. Its structure is relatively complex. Due to the limitations of the oil cylinder pipeline, etc., the occupied space is also relatively large. The flip platform is more common in other scenarios. For example, the patent CN221135826U, an easy-to-operate load-bearing flip platform, is a manual flip platform with relatively limited load-bearing capacity and cannot adapt to the use scenario of special tunnel equipment. The patent CN116905780A, an automatic platform flip mechanism, uses an oil cylinder to achieve flipping, with a complex structure and larger occupied space for related accessories, making it difficult to be applicable to tunnel construction. Summary of the Utility Model

[0004] The utility model provides a turnable manned platform for special tunnel equipment to solve the technical problem that the existing turnable manned platform of special tunnel equipment occupies a relatively large space.

[0005] According to one aspect of the utility model, a turnable manned platform for special tunnel equipment is provided, including a main platform and a platform mounting seat; the platform mounting seat is used for fixedly connecting with the special equipment, and a sleeve is fixed at the top of the platform mounting seat; one end of the main platform close to the platform mounting seat is provided with an extending end, an articulated block is hinged on the extending end, and a ladder is connected to the end of the main platform far from the platform mounting seat; the extending end and the articulated block are in sliding fit with the sleeve in the horizontal direction. By sliding the extending end and the articulated block, the main platform can be switched between the storage state and the unfolded state. In the storage state, the articulated block is located inside the sleeve and is in a horizontal state, and the main platform naturally droops around the hinge point under the action of gravity; in the unfolded state, the extending end is located inside the sleeve, making the main platform in a horizontal state, and the articulated block naturally droops around the hinge point under the action of gravity.

[0006] Optionally, a locking member is provided on the sleeve for locking the articulated block and the extending end.

[0007] Optionally, the locking member includes a limiting sleeve and a limiting pin. The limiting sleeve is fixed on the sleeve. The limiting pin is U-shaped and includes two insertion ends. Limiting holes are formed in both the hinge block and the protruding end. One insertion end of the limiting pin is used for insertion into the limiting sleeve, and the other insertion end is used for insertion into the limiting hole of the hinge block or the protruding end.

[0008] Optionally, an armrest mounting seat is fixed on the main platform. A movable armrest and a locking structure for fixing the armrest are connected to the armrest mounting seat. When the main platform is in the unfolded state, the armrest is parallel to the main platform. When the main platform is in the retracted state, the armrest is parallel to the main platform.

[0009] Optionally, the locking structure includes a locking pin and a second limiting plate. A sliding groove is formed in the armrest mounting seat. The bottom end of the armrest is slidably inserted into the sliding groove. The second limiting plate is installed at the end of the sliding groove to limit the rotation of the armrest. The locking pin is fixed on the armrest. A kidney-shaped groove is formed in the armrest mounting seat, and the locking pin is slidably engaged with the kidney-shaped groove.

[0010] Optionally, the armrest includes a first armrest and a second armrest on both sides of the main platform, and a third armrest on the side of the main platform away from the protruding end.

[0011] Optionally, a first limiting plate is provided at one end of the hinge block away from the protruding end. The first limiting plate is used to abut against the end face of the sleeve when the hinge block slides into the sleeve to limit the hinge block from passing through the sleeve completely.

[0012] Optionally, the ladder is connected to the main platform by a horizontally arranged bolt, so that when the bolt is loosened, the ladder can be flipped to a state parallel to the main platform with the bolt as the rotation axis.

[0013] Optionally, the ladder and the third armrest are arranged side by side on the side of the main platform away from the protruding end, so that the ladder and the third armrest do not interfere with each other.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. By flipping the main platform, the armrest and the ladder, the space in the height and length directions of the platform is effectively saved, so that the special equipment has better passability in the tunnel. At the same time, the platform flipping structure is simple, and the operator can quickly flip the platform.

[0016] 2. The main platform is set as a movable hinge structure. In the working state, the inner sleeve bears the force completely. Compared with the hinge point fixed structure with the pin bearing the force, it has stronger bearing capacity under the same size. At the same time, this structure enables the platform to be kept in the same vertical plane as the mounting seat after flipping, further reducing the occupied space.

[0017] 3. The armrest is set as an adjustable and retractable structure. By designing the maximum retractable stroke, each armrest can be stacked on top of each other, further reducing the occupied space.

[0026] The following will provide a detailed description of the embodiments of the present utility model with reference to the drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0027] The following combines the attached Figures 1-4 to further describe this application in detail.

[0028] The embodiments of this application disclose a retractable manned platform for special tunnel equipment.

[0029] Refer to Figure 1 and Figure 2, the retractable manned platform for tunnel special equipment includes a main platform 6 and a platform mount 14; the platform mount 14 is used for fixedly connecting with the special equipment, and a sleeve 5 is fixed at the top of the platform mount 14; one end of the main platform 6 close to the platform mount 14 is provided with an extended end, and a hinge block 2 is hinged on the extended end, and a ladder 12 is connected to the end of the main platform 6 far from the platform mount 14; the extended end and the hinge block 2 are slidably matched with the sleeve 5 in the horizontal direction, and by sliding the extended end and the hinge block 2, the main platform 6 is switched between the storage state and the unfolded state. In the storage state, the hinge block 2 is located in the sleeve 5 and is in a horizontal state, and the main platform 6 naturally droops around the hinge point under the action of gravity; in the unfolded state, the extended end is located in the sleeve 5, making the main platform 6 in a horizontal state, and the hinge block 2 naturally droops around the hinge point under the action of gravity.

[0030] Specifically, this application includes a main platform 6 and a platform mount 14. The platform mount 14 is fixed on the tunnel special equipment, and a sleeve 5 is installed at its top. One end of the main platform 6 is close to the platform mount 14 and is provided with a slidable extended end, which is connected to the sleeve 5 through a hinge block 2. The hinge block 2 can slide horizontally in the sleeve 5. When the platform is not in use, the hinge block 2 slides into the sleeve 5, and the entire main platform 6 naturally droops around the hinge point to the vertical position under the action of gravity, thus realizing storage and reducing space occupation. When the platform needs to be used, the extended end and the hinge block 2 slide out of the sleeve 5, making the main platform 6 return to the horizontal position to form a stable working platform. At this time, the hinge block 2 naturally droops under the action of gravity to ensure the stability of the platform. The function of this design is that when the platform is in the storage state, components such as the main platform 6 and the ladder 12 can be placed vertically, greatly reducing the occupied space of the equipment and enabling the special equipment to pass through narrow tunnels more easily. When in the unfolded state, the platform can provide a stable and spacious operation space for the operator to carry out various operations. This design not only realizes the effective utilization of space but also maintains the convenience and safety of operation.

[0031] A locking member is provided on the sleeve 5 for locking the hinge block 2 and the extended end. Its main function is to ensure that during the unfolding or storage process of the platform, the hinge block 2 and the extended end can be firmly fixed in the required positions, preventing accidental sliding or loosening of the platform during use or storage, thereby ensuring the stability of the platform and the safety of operation. By locking the positions of the hinge block 2 and the extended end, the locking member enables the platform to maintain a horizontal state during use and to be firmly placed vertically during storage, avoiding potential safety risks caused by accidental movement.

[0032] The locking member includes a limit sleeve 3 and a limit pin 4. The limit sleeve 3 is fixed on the sleeve 5. The limit pin 4 is U-shaped and includes two insertion ends. Limit holes are provided on both the hinge block 2 and the extending end. One insertion end of the limit pin 4 is used to be inserted into the limit sleeve 3, and the other insertion end is used to be inserted into the limit hole of the hinge block 2 or the extending end. Through the cooperation of the limit sleeve 3 and the U-shaped limit pin 4, this structure can stably lock the positions of the hinge block 2 and the extending end, preventing them from accidentally moving or loosening during the unfolding or storage process of the platform, thereby ensuring the safety and stability of the platform. In addition, since the limit pin 4 is designed to be U-shaped and has two insertion ends, the operator only needs to simply insert or pull out the pin to complete locking or releasing. The whole process is fast and does not require complex tools, greatly improving the operation efficiency. At the same time, this structure occupies a small space and is suitable for tunnel special equipment with limited space.

[0033] Referring to Figure 3 , a handrail mounting seat 10 is fixed on the main platform 6. A movable handrail and a locking structure for fixing the handrail are connected to the handrail mounting seat 10. When the main platform 6 is in the unfolded state, the handrail is parallel to the main platform 6. When the main platform 6 is in the stored state, the handrail is parallel to the main platform 6. By keeping the handrail parallel to the main platform 6, regardless of whether the platform is in the unfolded or stored state, the space can be saved to the greatest extent, while ensuring the convenience and safety of operation. In the unfolded state of the platform, the handrail is parallel to the main platform 6, providing necessary support and safety protection for the operator. In the stored state of the platform, the handrail is fixed at a position parallel to the main platform 6 through the locking structure, so that the handrail can be closely attached to the platform, reducing the overall occupied space and avoiding being disturbed or damaged in the tunnel or during equipment movement.

[0034] The locking structure includes a locking pin 11 and a second limit plate 13. A chute is provided on the handrail mounting seat 10. The bottom end of the handrail is slidably inserted into the chute. The second limit plate 13 is installed at the end of the chute to limit the rotation of the handrail. The locking pin 11 is fixed on the handrail. A waist-shaped slot is provided on the handrail mounting seat 10, and the locking pin 11 is slidably engaged with the waist-shaped slot. The bottom end of the handrail is connected to the handrail mounting seat 10 through the chute, and the handrail can slide in the chute. The second limit plate 13 is located at the end of the chute and is used to limit the rotation angle of the handrail to ensure that the handrail remains on a predetermined track during the unfolding or storage process. The locking pin 11 is fixed on the handrail and is slidably engaged with the waist-shaped slot on the handrail mounting seat 10. Through the sliding of the locking pin 11, the handrail can be fixed at different positions. When the handrail needs to be stored, first slide it to the maximum stroke position. Through the design of the waist-shaped slot, the handrails can move one by one in an orderly manner and be stacked under the action of the locking pin 11, so that multiple handrails can be closely stacked, reducing the occupied space. This design strategy ensures that the handrails will not interfere with each other when folded, while maximizing the space utilization efficiency of the equipment.

[0035] The handrails include a first handrail 7, a second handrail 8 located on both sides of the main platform 6, and a third handrail 9 located on the side of the main platform 6 away from the protruding end. Its advantage is to provide comprehensive operation protection and support, ensuring the safety and stability of the operator on the platform. By setting handrails on both sides and one end of the platform, the operator can obtain a firm grip point during operation to prevent accidental falls.

[0036] One end of the hinge block 2 away from the protruding end has a first limit plate 1. The first limit plate 1 is used to abut against the end face of the sleeve 5 when the hinge block 2 slides into the sleeve 5 to limit the hinge block 2 from passing completely through the sleeve 5. When the hinge block 2 slides into the sleeve 5, the first limit plate 1 abuts against the end face of the sleeve 5, thereby restricting the continuous sliding of the hinge block 2 and preventing it from passing completely through the sleeve 5. This design ensures that the hinge block 2 can be accurately positioned during the sliding process, enabling the main platform 6 to maintain a stable position in both the deployed and stowed states, avoiding platform position deviation or functional failure caused by excessive sliding of the hinge block 2, thus ensuring the reliability and safety of the platform.

[0037] The ladder 12 is connected to the main platform 6 by horizontally arranged bolts, so that when the bolts are loosened, the ladder 12 can be flipped to a state parallel to the main platform 6 with the bolts as the rotation axis. This design connects the ladder 12 to the main platform 6 by horizontally arranged bolts. When the bolts are loosened, the ladder 12 can be flipped to a state parallel to the main platform 6 with the bolts as the rotation axis. Its function is to facilitate the folding and storage of the ladder 12 when it is not in use and place it parallel to the main platform 6, thereby reducing the overall occupied space of the equipment and improving the passability of the tunnel special equipment in narrow spaces. This design not only simplifies the operation and storage process of the ladder 12 but also ensures that the ladder 12 can be quickly restored to the working state when needed, providing a convenient operation experience.

[0038] Refer to Figure 1 and Figure 4 As shown in, the ladder 12 and the third handrail 9 are arranged side by side on the side of the main platform 6 away from the protruding end, so that the ladder 12 and the third handrail 9 do not interfere with each other. This design connects the ladder 12 to the main platform 6 by horizontally arranged bolts. When the bolts are loosened, the ladder 12 can be flipped to a state parallel to the main platform 6 with the bolts as the rotation axis. Its function is to facilitate the folding and storage of the ladder 12 when it is not in use and place it parallel to the main platform 6, thereby reducing the overall occupied space of the equipment and improving the passability of the tunnel special equipment in narrow spaces. This design not only simplifies the operation and storage process of the ladder 12 but also ensures that the ladder 12 can be quickly restored to the working state when needed, providing a convenient operation experience.
